Traps are a common mechanism in Survival Multiplayer (SMP) built by players to kill other players or mobs automatically. The following is a list of basic traps with a short tutorial that often assumes the reader has a working understanding of the basic concepts required to build the trap. Traps are considered a subset of mechanisms.
Traps are devices designed to trap or damage a entity or entities, also known as "the target."
Explosive traps
The traps here primarily use TNT to cause harm to the target.
A good idea when testing Explosive Traps is to use a block such as a Redstone Lamp, which, like TNT, triggers with Redstone Power, but has less explosive results, so you don't lose an intricate trap due to careless TNT ignition.
The landmine
A simple landmine
The landmine by itself is very inefficient and non-lethal. It damages the landscape and deals little if any damage to players. To make it more efficient, there are several variations you can use:
If you want to protect the landscape, you can place water at the bottom of the hole. It will reduce the dealt damage, however.
By digging a pit underneath this, the player might fall into it.
Try to camouflage the landmine by making it less noticeable, e.g. grow tall grass around it.
Instant landmine
Side view
If you are getting annoyed of wasted TNT because people run away from your landmine filled with tons of TNT, you should build a landmine that explodes instantly.
First, dig a 3x3x3 hole in the ground, jump in then stand on a corner. On the bottom center, place a block of dirt then place a rail on top of it. On the rail, place a minecart with TNT (Be careful not to accidentally push the minecart!). Destroy the block under the rail to derail the minecart. The minecart will fall one block lower, this won't really cause any damage unless you accidentally pushed the minecart. Dig the block below you then place a dispenser facing downwards which makes it face the minecart, load the dispenser with flint and steel. Surround the minecart with 8 TNT blocks, after this, surround the dispenser with 8 TNT blocks, too. You should be above ground by now, cover the TNT-filled hole with dirt, remember where the dispenser is. Finally, place a pressure plate on top of the block above the dispenser.
Redstone mine
The redstone mine. Replace the glowstone with redstone ore.
Dig down 2 blocks
Place down a redstone ore (silk touch pickaxe required)
Then place a daylight sensor or BUD under the redstone ore
Place as much TNT as you want under the redstone ore connect it using redstone dust
Wait for someone or something to step on the redstone and boom watch what ever set it off explode in to nothing but bone and rotten flesh.
Hopefully if properly done, an unsuspecting player will trip the trip wire and get blasted by the TNT.
C4 trap
Dubbed so by Bannablarg, the first to use this with success, this "C4" is a vertical or horizontal stack of TNT with a dispenser wired to a button with a fire charge in it. The dispenser is placed one block above or below the stack (vertical) or one block next to the stack (horizontal). This usually works better for demolition than for a trap, if you want that, you can wire a pressure plate to the dispenser. This works like a flaming arrow hitting a stack of TNT from above. This is another way to remotely detonate the TNT, via flaming arrow. This works better than a dispenser shooting TNT, because the "C4" stays in one place. Also, if only two TNT blocks are used, it works well as a disposable cannon, even better on obsidian blocks, but not in a tube. All evidence of the trap is usually destroyed. Note: C4 trap from below does not work very well.
The hidden house
This trap is the opposite of a TNT door trap: The TNT is obvious, while the house is hidden. Make a field of TNT extending about 5 blocks into the ground. Place signs all over the field saying: "Find my hidden house." It lures people in twice: the TNT danger, and the hidden house challenge. The problem is that there is no house! Beneath the field are pressure plates which ignite the TNT, leaving no time to escape, as you are in a field of TNT 6 blocks under.
TNT house
This trap is obvious... too obvious. It's a house of TNT. It obliterates everything near it: blocks, buildings, mobs, players, you name it. People will go around it and within it because they think it's only activated when someone goes in. The more layers, the more obliteration and the larger range. Now follow one of these versions:
Suicide: You activate manually from inside.
Murder: Activate it from a distance with a redstone trail.
Genocide: Make the house very thick and activate it from a distance.
The Man: Build a Player-Sized copy of the character. Surround it in TNT armor.
Automatic variations:
Try putting a metal door on the TNT house. If the player is new or just distracted they'll hit the button to open the metal door, igniting the house.
Make a house with a table using a pressure plate by the wall as the top. If the player starts to confidently loot it, they likely will forget about the table.
Blow and burn
Griefers love blowing and burning people's houses up. This trap turns the grief onto the griefer.
Make a decoy house out of wood or wool (preferably wool).
Fill the area under it with TNT and make some "rays" of TNT extend from the house.
If a griefer happens to burn the house down, they will probably get a bit more of a bang than they expected!
Defuse me landmine
Use MCEdit or some other method to get a bunch of floating sand with a pressure plate under it. Then underneath the sand place a bunch of TNT with pressure plates on top. If a player breaks the pressure plate, they will fall onto the pressure plates just to go flying back up.
Piston trap
Piston trap
Build what is shown in the schematic and make sure a roof over it so that when your target hits the pressure plate it cannot escape. This trap is best for small 1x2 passage-ways, perhaps inside a friend’s mine. When the pressure plate is stepped two pistons push up, blocking the "happy" miners escape and ignites TNT. This trap can alternatively be used as an above ground mob trap, just make sure to remove the TNT.
This is a very simple and rather obvious trap that is made by putting a pressure plate in the middle of 4 open doors so that the victim is trapped inside when they enter. You may also decide to put a roof to prevent the victim jumping out. This is a very quick and easy to set up trap, making it ideal if you are new to Minecraft or simply in a hurry. This trap more useful against mobs, such as zombie villagers, so you don’t always have to use iron doors.
Pitfall traps
Pitfall traps usually use fall damage to harm the target. Sometimes the pitfall is used as an area the target can't escape before fatal damage has been dealt. Different players prefer to use fire, lava, and/or cactus to deal damage.
General improvements
Some minor variation can make a simple pit much more deadly.
Make checkardboard of cacti at the bottom of a pit. Cacti do destroy items though.
To effectively improve the size of your pit without digging a larger area, dig a shallow ring around the top layer of your pit. Fill this area with water so that mobs will be dragged to the center. If necessary, water can be stopped by placing signs or Stone Pressure Plate. Note that this will reduce fall damage.
Fence trap
Construct a hallway with a sand, or gravel, floor for an unsuspecting player to walk through. A diagonal hallway works best. Place fence posts underneath the path and drop the material for the floor on the fences. Below the fences, you can have a pit.
This works because when a gravity-affected block falls on a fence post, the block stays as an entity. As a result, a player walking between the fence posts will fall through the sand entities, causing them to plummet. Diagonal hallways make it more likely to fall through the sand without landing safely on a fence post. Keep in mind that the sand is going to look half a block higher than a normal block, but this can easily be covered up. The best part: it does not need to be reset!
TNT pitfall
Build the basic landmine and dig a pit under it. When the TNT ignites, the sand or gravel will fall and the target will be trapped until the TNT explodes.
Shallow pitfall
Dig a pit 1-block deep hole at least 5x5 blocks. Place fences on the inside edge. Since fences count as one and one half blocks in height, mobs can walk in but can not jump out. Alternatively, line the outside with half-slabs.This can also be combined with a mob grinder, via water currents leading to it. Zombies and Skeletons will take damage from sunlight during the day if the pit is uncovered, making this an effective way to sort out creepers. This design does not capture spiders.
Fake water pitfall
Dig a hole (2x2 works best) at least 30 blocks deep, the deeper the better. At the bottom place lapis lazuli or other blue blocks. Add a false corridor at the bottom to make it look like it goes somewhere. When an unsuspecting player comes across the hole, they may think that there is water at the bottom, jump down and die. Experienced players are less likely to fall for this particular trap but it generally works quite well.
Snowball knock back
Load a dispenser with snowballs (or other knockback item), and connect it to a pressure plate. When the target walks across the plate, the dispenser, if aimed correctly, shoots a snowball and knocks the target into the pit.
Piston pit
Automatic piston pitfall
Place the piston so it pushes the block the signs are on. You can make up to twelve rows using one piston. Make sure there is a block of empty space at the end of where the piston pushes. Connect the piston to a trigger, such a pressure plate or lever, and when the piston moves it should break the signs and cause the sand to fall along with the target!
Block pitfall
Beside the classic pressure plate activated pit fall trap, you can also trigger the mechanism with a block - when removed the block will cause the pit to collapse.
A compact & fast design, can kill the target by any type of damage. Cheap & fast to build, yet does the job right and is almost undetectable. The victim is walking in a tunnel, there are no pressure plates, just a tripwire hanging at the target's head level. Once the victim touches the tripwire, a block is pushed up preventing the target from escaping and the pistons below quickly open up a hole and the target falls down in a pitfall. From there, you can do anything with the target.
Make what is shown in the schematic, like an water elevator with water only at the top. Make sure the hole is 30-40 blocks deep, which is enough to kill the player. It could help to place a lure sign near the 'elevator' saying something like "Do not enter!" You can also make the signs' text something like a floor countdown like "35", "34", "33", etc. so players are more likely to fall for the trap. If you want, you can place hoppers and with chests so you can gather the loot from the victims, but if you really want the drops, you need a secret passage to the bottom of the pit for collection.
Floating sand pitfall
Floating sand pitfall. Replace vines with double tall plant.
If you make the shown pitfall, when you break the grass, the sand should remain floating. If you touch the string, it will cause a block update which causes the sand to fall.
Proximity Trap
A proximity trap is a player detector paired with an output.
A false-floor trap is a variation of a pitfall trap. It works by creating a concealed safe route through the pitfall (which is usually very big) to allow authorized players to pass, while catching unauthorized players or mobs and killing them. It generally works best when there is no way around, forcing the player to pass through the trap.
Dig a pit. The deeper and longer the better.
Place use TNT to build a bridge across the pit. It should be at least 2 blocks wide, preferably more as someone could cheat otherwise.
Replace some of the TNT with torches. Read the next step to understand which ones to replace.
On top of the torches, place sand or gravel. Try to get across the bridge now by only stepping on the sand. Make sure you can do it, because it will be even harder at the end as you must stay off the edges of the sand.
Once you have picked a satisfactory path, cover up the TNT.
If anyone steps on one of the pressure plates with TNT under it, the TNT will explode causing the whole bridge to collapse! Note: You will need to have something under the TNT, perhaps more TNT or something easily destructible to make sure the TNT doesn't fall and fail to ignite the rest of the TNT.
Triggers
The traps here are most notable for their trigger and can be connected to many different mechanisms of harm.
Trapped ore
Trapped ore. Replace the cobblestone with ore.
When someone mines the ore the TNT will explode! Be sure to place the torches before the TNT and to not place any TNT next to a lit torch.
Trapped ore 2
Use a piston to push a TNT next to a redstone torch when a block is mined. The advantage of this method is that the trapped block does not need have wires right next to it and that it can cover a wider area.
Normally people would expect chests to explode, so this trigger will surprise them as soon as they loot your furnace.
Fill a furnace with coal, iron and food (you decide).
Put a comparator leading away from the furnace. It should turn on.
Place a block in front of the comparator.
Place a redstone torch on the block, it should turn off.
Create a redstone line from the torch to TNT.
If a griefer loots the furnace the comparator will deactivate and the torch will turn on, blowing the victim to bits!
Wrong lever
Place several levers on a wall and put TNT behind it. Place a sign saying something along the lines of, "Which one...," "Don't pull these!," or "Passcode entry >." Eventually a player with too much curiosity will come along and pull a lever.
SCR trap
The SCR trap
This trigger detects when a redstone circuit is broken, such as when a griefer is destroying your house.
If someone puts something inside the chest, it will go into the hopper, turn on the comparator, and I think you know the rest. You could attach the comparator directly to the chest, but it would be more obvious as you can see over chests.
Fishing trap
It is possible to detonate TNT that has a pressure plate on it using a fishing rod. This method is undetectable; however, it is unstable and prone to premature detonation if you don't have patience.
Note that this trap seldom works on players, as they will most likely avoid the pressure plate. For maximum effect, it is suggested that you place the trap in front of an iron door, as they are usually paired with pressure plates for easy opening.
Exploding bed
Connect a bed next to a BUD, the bud to some TNT, and cover the whole thing in cobblestone. Then just wait for the player to sleep in it and get blasted sky-high!
Fundamental traps
All traps in here only catch newer players, but are fundamental ideas that capture the essence of branches of trap creation.
Anti-Totem Trap
Most trap effects can be negated with a Totem of Undying, which will save the player if a fatal hit is taken. This design takes into account the possibility of the player thinking it's a trap and bringing strong armor and a totem of undying.
Self Operating Pitfall
This trap is simplicity itself. No redstone, no commands, no manual activation, just good old fall damage!
Materials: 1 Chest, 25 Gravel, 24 Carpet (Optional), and 25 2 block high Flowers.
Dig a 5x5 hole to a desired depth, leaving one layer of dirt 3 blocks from the surface.
Place the flowers on the layer of dirt, and the gravel/sand on top of the flowers.
Place a chest in the center, and the carpet around the chest.
Remove the dirt holding up the flowers. The gravel should not fall.
Wait until a careless player opens the chest, and watch them fall to their doom!
Tips:
Consider building a decoy house around the trap to fool players into thinking they're raiding a base, this makes the carpet much more inconspicuous.
Consider adding hoppers at the bottom of the trap to collect the loot.
Trick Trap-The concept of confidence
This trap may include loss of precious items, such as golden apples, so only use this if you are very rich.
Set a chest (not trapped) and put diamonds or other valuable stuff in it.
Then put TNT on the walls, making your raiders think it will blow up in certain situations.
Then put another room with a iron door, but don't put a pressure plate behind it, and put two spawners or more (with any hostile mob) and hide them. However, spawners are only available in creative mode, so if you want to make this in survival, you must find a naturally generated dungeon and build your trap around it.
Put another chest (again not trapped) and put more valuable stuff in it.
The raider will think they are safe and go for the chest but the mobs spawned by spawner will very likely kill them.
Noob + Pro Chest drop trap
Dig a 2x2 hole until you reach bedrock, or a reasonable drop.
Place 4 hoppers, one per block on the 2x2 hole, pointing into chests.
At the top of the hole, place 4 double chests (so 8 chests in total) around the hole.
The player may try to sneak to the edge of the chest to look down the hole. Because the chest is smaller than a regular block, the sneak function will not prevent you falling. They will die of fall damage and their items will fall into the hoppers and chests, where you can collect them.
Fake chunk error
Dig a 16 by 16 hole (preferably in line with real chunks) at least 23 blocks deep. Some inexperienced players may think it is a chunk error and walk in, but they will fall to the hole and very likely die from fall damage. If they for some reason don't die from fall damage (maybe they use feather falling boots or strong armor), you can be waiting in the bottom equipped with at least iron sword and armor so you can kill everybody who falls to the hole.
Digging your own grave - tricking with trust
Ask someone if they could dig down at a spot because you lost many diamonds there and they could take half. When they get far enough, you can cover them with gravel or sand. You can also use lava for a more dramatic death, however, this will destroy their drops as well. Please note that only very inexperienced players will be fooled by this trap.
Hide the pit with sand, supported by signs, like in the diagram.
(Optional) Make a house around the Sand. If you do this, you will probably want to put in carpet.
(Optional) Attach a Piston to the bottom block of sand. You can use this to automate the trap. If you want to retract the piston when a Pressure Plate is pressed, use a not gate.
Wait for an unsuspecting player and break the bottom block.
Make sure you aren't underneath the sand or have cover when it falls.
Make a 2 block high hallway that is a length of your choice and build the floor out of obsidian.
Place the Pressure Plate somewhere in the middle.
Place four Pistons underneath the floor surrounding the pressure plate, so that when they extend, they will trap the player.
Run Redstone Dust underneath the floor so it will turn on the Piston when the Pressure Plate is touched.
(Optional) Place signs or other lures to try to get a player to go into the tunnel.
When an unsuspecting player or mob hits the Pressure Plate, the Piston will push the floor up trapping the player. This trap will not work on players with diamond pickaxes, as they can easily just break the floor or dig out. Also, a stone pressure plate is fairly easy to spot in the obsidian floor, so you can replace the obsidian with stone or cobblestone to make a harder to spot but easier to escape variant of this trap.
Create a Minecart track and place a Minecart on it.
Somewhere on the track, place the Detector Rail.
It might help to diguise the detector as doing something else, like switching tracks, opening a Door, etc.
Underneath the rail, place either TNT or run Redstone to another trap, eg. Pit Trap.
Somehow get players to ride the Minecart:
Place a sign saying something like, "Village this way -->", or "Private Mine Entrance; DO NOT ENTER!"
Make it look like a fun roller coaster.
A sticky situation - the concept of quirks as trap mechanics
You will need (for 1 trap, you might want more for better results):
Soul Sand- 15 blocks
First, make a 1x3 hole in the ground. On the edge, build 3 blocks high (later you will destroy these).
Now make an outline of it, but on the level you just created. If you are on a flying server, you might want to add a roof, which is an extra 3 to 12 blocks of Soul Sand. When your trap is complete, human-sized mobs - such as zombies and skeletons - or other people will walk into your trap and can't walk out. Also, if you place ice under the soul sand, mobs and people will move even slower due to the properties of ice.
Make a box home from planks, with a door and a pressure plate outside.
Under the pressure plate, put as much TNT as you wish, just like in the exploding door.
Place a sign outside that says something like "please don't grief my home thx."
Griefers or robbers can't stand not griefing a house like this. They will likely walk through the door, trigger the TNT, and blow themselves to the moon!
Using trapped chests are also good, especially if the griefers can't tell it is one.
Painting Trap
A Painting Trap. Place Painting(s) instead of vines.
Materials: A Painting, 2 Signs, (Optional) Hopper, (Optional) Chest
This is a very easy to make trap which plays on the old secret passage behind the painting trick.
Make a pit off of the side of your house.
Place the two signs at the end of the hallway leading to the hole.
Place paintings on the signs, so when someone walks through the painting, they fall to their death.
At the bottom you could have some means of collecting items.
Instead of a fall, you could use lava or some other form of death.
Facebreaker trap - the concept of obscure damage
What you need: Five blocks of any kind, and as many gravel blocks as possible.
This is one of the most simple traps in Minecraft history, although it would be easily noticed by intelligent players. Works more effectively on new players. First, make a tower that is five blocks high. It doesn't matter which kind of block you use. Then, on the very surrounding area on the tower you made, dig holes three blocks deep and three blocks wide to make a pit surrounding your tower. Dig another hole close to your tower, just one block deep for you to hide in. When an unsuspecting target comes too close to the tower, he would fall in the pit. After that place several Gravel blocks beside the 5th block on your tower, aiming downwards on the target. If done correctly, the gravel blocks should fall on your target's head, thus trapping or killing him. Hence the name facebreaker.
Note: You will need to use atleast two blocks of gravel to kill a player, and this can actually be used as a convenient elevator. Placing more gravel blocks is advised, and it is also advised that you place them quickly. Otherwise, if you take too long, the player may jump up from the first gravel block (their feet will be in it), and not be suffocated by the second.

This is a simple trap that can be made without too much work.
1. Build a large wooden rectangle resting on its side.
2. At the top of the rectangle build a large cobblestone box.
3. Break a hole in the bottom of box.
4. Place a chest at the bottom of the rectangle.
5. Place sand from the hole in the cobblestone box.
6. Fill the cobblestone box completely with lava.
7. Add some leaves. Make sure it looks just enough like a tree to blend with the forest, but not so much that people will not notice it.
The person will be fascinated with the tree and will enter. The person will see the chest, and, thinking there is loot in it, will break the sand blocks in order to open the chest. As he breaks the sand blocks, the hole in the box of lava is unplugged, causing lava to flow onto the victim. This will definitely NOT work on experienced players.
This trap relies on fall damage to damage the enemy and the pressure plate must be replaced after every use. NOTE: This trap does not work on Chickens, Ocelots or Magma cubes.
Don't run - The concept of curiosity killing the cat
Please note that only really inexperienced players will be fooled by this.
This is a very easy trap to build. Go into a cave and dig at least 36 blocks down. Dig a 4 block deep pit and put water in its second topmost layer. Have blue wool, signs/ladders, a pickaxe and a chest ready. Also build what looks like an entrance to a base at the bottom of the trap. Now get a player and tell him that he's found someone's secret base. Jump into the water and quickly submerge yourself in the pit. Put the signs/ladders to give you air bubbles to breathe. Tell the player on top that you'll put water on top of the pit so he and you can escape. Instead of water, use the blue wool to cover up the pit. Signal the player to jump and when you see his death-message, dig your way out and collect all the loot.
Greed
Traps that exploit a player's natural desire for riches in order to lead him or her to their downfall.
"Villagers giving you the Finger"
Find a blacksmith villager house. Replace the chest with a trapped chest. Put lots of tnt underneath so that they cannot outrun the explosion. When they open the chest, the sound of TNT will make them run. The TNT will completely destroy the blacksmith house, and mostly everything around it for at least 20 more blocks. This will either kill or greatly injure them. If you want to sacrifice most or some of a village for this, then do it. Take all items out of the chest first.
DIAMONDS!!
(This trap may not work on experienced players; they might know the difference between trapped chests and chests.)
Make a wood house, and put 2 signs outside saying DIAMONDS INSIDE! COME IN! Make chest full of diamonds if you make this on creative or are really rich. Make a door that leads to another room with a chest. Put a sign above the first chest saying MORE AHEAD! Then put a trapped chest down in the other room. Put some TNT uder the chest. Put another sign saying: DON'T OPEN THIS CHEST! or something like that. When griefers open the chest, they'll blow up!
Note: You can vary with other expensive items.
The house of death
This is a very simple trap, but is very effective. It requires redstone dust, redstone torches, glass, redstone repeaters, a trapped chest, lots of cobblestone, and lava. First dig a 5x5, 4 block hole in the ground and fill it with lava. Cover the next layer with glass. Put pressure plates everywhere connected to dispensers filled with lava buckets. on the top layer, cover it in cobblestone. Build a cobblestone house around it. In the middle, put a trapped chest. Put some pistons under the floor and wire them to pull back the floor when the chest is opened. Put a sign above the chest saying "Diamonds/Emeralds in there-if you take them I will kill you!!!!". Make an entrance with an iron door with a pressure plate outside, and ONLY on the outside. Then the trap is set. How it works: the players will see the chest and get curious. They walk in the one way entrance and open the chest. The chest makes them fall into the underground lava area. They fall on the pressure plates and cause the dispensers to unload the lava-they'll be dead in the snap of a finger.
Note: You will not be able to collect your loot as it will incinerate in the lava.
EDIT: If you place signs under the lava. then they will fall through the lava, but unless they are quick thinking and have a water bucket, they'll still burn to death, but you can keep their stuff.
Build a 3 block deep hole. Surround it with burning netherrack on all but one side. Put a block of diamond on top WHILE INSIDE. Continue digging downwards until you are at least 24 blocks deep to ensure death. Make a square room with torches and wait inside. When someone steps onto the diamond and breaks it, he will fall. If he dies when he hits the ground, the trap is a success. Collect the loot and leave. If not, the hole isn't deep enough. In this case, quickly kill the surprised player and claim their loot.
However, one may see the ruse and disarm the trap, possibly by filling your trap with lava, water, gravel, or sand, or by covering the hole with obsidian. They may also return with a friend to help attack you when you come out.
Optional: Put more diamond blocks below the visible diamond block, so your victims think it is not a trap.
This trap depends on people's natural greed, and the fact that sometimes people just don't think.
Another way is to put the diamond block over one and put down two. On the bottom one, put a torch and put a block of gravel on top of the torch. On the bottom of the hole, put a pressure plate so the gravel gets destroyed.
Optional: Use blocks instead of rare ore, because ore looks natural.
Build a straight line and put TNT behind glass and some redstone so people think they've activated the TNT. They'll see a redstone repeater and go activate it, so it locks and stops it.
The trick is to put a fake redstone line and make a new line behind stone before the redstone repeater so it actually doesn't go off. It sets off without them knowing and the whole cavern blows up!
If you want to keep it, I suggest hiding it under the redstone repeater latch activation switch so a bit blows up, but the contraption is safe.
Fake mine
You need: Lots of TNT, a structure that looks convincingly like a mine or an abandoned mine, a trigger, an iron door, and some redstone.
Preparation:
1. Put your TNT below the layer on which the victim will be standing.
2. Place an iron door for players to "enter" the mine.
3. Wire the trigger to the TNT, but make sure the trigger is near the door.
4. Place a sign near your "mine" saying "Diamond Mine".
5. Wait for your first unfortunate victim.
Execution of trap
1. Victim notices your "mine" and thinks you might have diamonds or other valuables stored inside.
2. Victim sees trigger and assumes that it's for the door.
3. Victim activates trigger and gets blown sky-high.
Inexpensive greed trap
Materials needed: Chest, TNT, Pressure Plate and redstone(optional).
Place a chest at the end of a long, 2 block tall hole made of stone or dirt. In front of the chest, dig a hole 1 block wide and two blocks deep. Place a TNT block at the bottom, a normal looking block on top of that, and finally a pressure plate on top. You can place more TNT underground along the length of the passageway ( but make sure to cover them all inconspicuously because when the player hears the TNT igniting they will probably run back).Whoever steps in front of the empty chest will ignite the TNT. You will need to rebuild the entire trap after each ignition. To ensure death at the cost of more resources, place redstone wire under all of the TNT so that it all ignites at once.
Curiosity trap
Make a chamber that has one entrance and an iron door that is opened only by a pressure plate on the outside, so that once the player is in, they are trapped. This trap can be escaped in three ways, and all of them can be anticipated. To prevent the victim from digging out, put lava behind the walls and beneath the floor. To prevent him from using their own lever or pressure plate to escape, place TNT underneath him or behind the walls or use glass on the wall. To stop him from destroying the iron door, place lava above that too.
Advanced Version:
Since it is somewhat obvious if you can see through the door or if you look in through the open door before entering the chamber (say chamber instead of room so it's more ominous sounding), there is a better version. Build the trap, but with another iron door. When you place the second door, make sure you place it with the alignment so the door is naturally open and the pressure plate or button visible. Then, place a lever outside next to the door and flip it so that the door closes. If a powered door receives a second signal, it has no effect. This will trick even the smartest players, thinking the other door openable and that if TNT lies under the floor linked to the "exit" door, they can run out and if they step on the entry door plate and don't enter to test if it links to that one. Optionally, you can make a "Blast Chamber" version by placing one or more TNT blocks beneath the floor that would be set off by the "exit" door's plate.
Dispensers in disguise
This is a very fun trap.
It will require:
Dispensers
Arrows
Tripwire hooks
Stone pressure plate
Lava
Build a long hallway, preferably 20 blocks long. Replace the sides of the wall with dispensers, and fill them up ( should be done in creative mode ). Then, make a curtain of lava to hide the dispensers. Add a chest with valuables. Then, place obvious tripwire hooks. The enemy player should disable the tripwires, but forget that the floor is pressure-plated. Arrows, set afire by the lava, should start impaling the player. Even if they turn back, they'd get hit by flaming arrows and burned to death.
Greedy rails
Make a long Powered Rail, powering all but the first rail. Put a Minecart on the first rail and a switch to make the cart move. Put a sign nearby that says "(your name)'s diamond cave, do not enter".
Building the track
Make a long track uphill with a drop-off at the top. Where the minecart drops, make a 4x4 hole 2 blocks deep and fill it with lava, so that the player will fall suddenly into lava and lose all of their fortunes. You may use a bucket of water to get rid of the lava.
Note: Make sure the lava isn't visible prior to the drop-off to prevent the player from jumping off. Also, because of the lava, you won't be able to collect the victim's drops.
Another way is to make a long tunnel down, with regular rails, and when the rails turn a corner, put lava. Best if you have torches all along the tunnel so the person doesn't get wind of what is about to happen. You could also have a vertical tunnel straight down and have the minecart drop the victim there. That way, you could be able to collect the drops.
Failed mine
This simple yet effective trap requires an ore (any kind will do), and at least 2 blocks of sand or a stream of lava above it. You may want stone around the ore for a natural look. Just hide the sand. Now set the ore where you want it above the victim. It HAS to be above the victim. Otherwise this is useless. Now climb up above the ore and put your sand or lava. Cover it with dirt, or even better, stone. Now remember to NEVER mine the ore. This also has to be on a server (mobs don't mine). Beware! Creepers can blow it up! This also works on any version of Minecraft.
An alternate version would be to use anvils rather than sand to deal massive amounts of damage to the player before suffocating him.
Simple ore trap
A very easy, cheap, but effective trap. Put iron or other ore anywhere. Place a redstone torch on back. Now, place another redstone torch, on the side of a block. Put wires connecting the torch to the top of that block. Make it activate any kind of killing mechanism, such as retracting pistons.
There is another trap that you put water 4x4 three blocks down then lilypads on top ,place sand on the lilypads and string on the sand then place any block where the water is so it is being replaced by the block then break the replaced block and vōila when a player walks on the string or breaks the string they fall end of story .
Fiery floor trap
This is a somewhat expensive trap with varying success rates. The larger the trap, the higher the success rate. First, dig a hole two blocks deep (size doesn't matter but does affect price). Next, cover the bottom of the hole with Dispensers, leaving a one block area on each edge to be filled with two blocks of your choice. Place a chest or Diamond Block on top of one of these stacks. This will serve as bait. Leave the other space filled, but do nothing else to it. Fill each Dispenser with Fire Charges and cover with Wood Planks or Stone and then cover the solid block with a Wood or Stone Pressure Plate depending on which block you used. Next, build a wall around the now-covered hole and place an Iron Door opposite from the bait with a Wooden Pressure Plate in front of it. Leave the block behind the door uncovered. A roof is recommended but not required. When an enemy enters the trap, they will go for the bait and walk on the Pressure Plates, activating the dispensers underneath, which will launch Fire Charges at them. The victim will be unable to leave due to the absence of a pressure plate to open the door from inside.
You can also, with this same concept, create an extremely effective mob trap. place a 3 by 3 square of pressure plates. Connect these via redstone to three dispensers filled with fire charges. Then all you have to do is build a shelter and watch the fun. Note: this trap relies on huge amounts of luck and is very expensive. Also, take care when retrieving the mob drops, as it is easy to fall victim to your own trap.
Pond of death
You will need: wood pressure plates, water buckets and TNT.
First, dig a 9x9 hole (size varies) that is 4 blocks deep. Then, place TNT on the bottom, place some blocks on top of the TNT, place the pressure plates and apply water. Voila!
Execution of trap:
1. Victim will see trap.
2. Victim will fish, causing the plates to be triggered.
3. Victim will be blown up.
The exploding diamond
Yes, this trap is the mother lode. Once they break the diamond, it will explode almost instantly, unlike any other TNT trap (when TNT ignites, it will have a 4 second cooldown timer). This will guaranteed it will grief players and see their bloody guts splattered on the walls of the crater.
You will need:
A lever
9 Minecarts with TNT
A piece of redstone
A diamond block
A Dispenser
Flint and steel
A redstone torch
A rail
Here's what the trap will look like on the side:
First, dig a hole three blocks deep and 6x1 blocks wide. Look at the picture above to help you see what it is look like. Place a diamond block on top of the hole so it is covering it, but sticking out. You must place the lever underneath the diamond block and switch it on. Place a block 1 block below the lever and place redstone on top of the block. Place a redstone torch on the side of the block. It should turn off when placed. After that, place a dispenser facing the direction of the torch and put flint and steel inside it. Then, place a rail next to the face of the dispenser and place 9 Minecarts with TNT onto the rail. Carefully break the rail and your trap is done! When someone tries to mine the diamond block, they will get an explosive surprise!
Semi-Advanced Traps
Many traps require some redstone wiring, but these take a significant amount and require a basic understanding of redstone circuitry. Explosive traps, those that use TNT, may destroy sections of redstone wire if the explosion occurs too close.
Invisible tripwire
This trap relies on the fact that like end portal, trip wire is invisible from the bottom. Make a room or hallway at least 3 blocks high, and put trip wire in a layer on the third layer up. If the victim jumps, they will trigger the trap. How they are captured or killed is up to the player.
Arrow dispenser
A simple arrow dispenser
By connecting this to a trigger, you can rapidly fire arrows at the target.
Some variations:
Place lava in front of the dispenser to catch the target on fire.
You can adjust the repeater which will change the speed. You can also completely change the clock if you don't have quartz.
You could use this to knock the target into a pit.
Attach this to a RS-Latch to keep it on until a button is pressed.
Crushing trap
A piston suffocation trap
This is ideal at the end of a water flow mob grinder as it minimizes drop losses. The design can be expanded to make a long row.
Dig a pit under it. It should be at least 5 block deep.
Place cobweb or something for the spiders to spawn on.
Break the torch and allow the pit to fill with spiders. You need to be withing 15 block for this to work.
Get a player to go into the pit somehow.
Water traps
Water traps generally use water to slow, drag, or drown the target. They sometimes also use water to prevent TNT from damaging the landscape. The traps here use water as the main component to trap or harm the target.
Fake water elevator [upcoming:Lua error in Module:Version_link at line 112: attempt to concatenate local 'text' (a nil value).]
You need: 1.13+, water, a hard block, and soul sand (pistons optional)
Step 1: Create a 4x3 outline of your block of choice on the ground, preferably tough blocks (hay bales work well on op factions due to being unaffected by efficiency). Put fill in the middle with soul sand (you need 2 water spaces to work the bubble column). Now build the rest as if it were a normal 1x2 water elevator, BUT you cap off the top (no exit). A locked iron door can be added at the top if you want the loot.
Step 2: Add in water at the top. When it reaches the bottom, it will trigger the upwards bubble column of the soul sand blocks. The way this trap kills is the player steps in, believing it is a path to the top of your base, and is drowned since they can't escape the current. Obviously, a lone water tower is suspicious. You will need to add a fake skybase up in the air, high enough that the player will not attempt to pillar up.
Step 3 (optional): To make it possible to kill high-end players, or do something on an op factions server, you need to hook up pistons to the top 5 blocks of the system (1 air block between a piston and a block), excepting the cap blocks right above the water sources, and provide a fast pulsing current. This resets the block's damage, so players cannot bust out without very high levels of efficiency. Add a lever to stop the current so you can loot your trap.
Pros:
Hard to spot until it is too late
Silent until the top
Requires a player who wised up to break it, doesn't need resetting
Medium investment to kill early-mid game players
Fast set-up
Cons:
Takes a long time to kill
Hard to loot
Can be like a high-tier version of landmines (being treated like a pressure plate in the middle of a desert).
Players may tower up to skybase anyway
Whirlpool trap [upcoming:Lua error in Module:Version_link at line 112: attempt to concatenate local 'text' (a nil value).]
You need: 1.13+, deep water, magma blocks, and a lot of kelp
Step 1: Choose a watery area which has reasonable player/mob traffic
Step 2: Dig out a 2 deep hole where you want your trap, put hopper collection system on bottom layer. The space where the magma blocks will be should be at least 7 blocks below sea level.
Step 3: Put magma blocks at least 7 blocks below sea level (depends on your capability to swim up and down). There is no known maximum distance (tested with deep ocean ravines), however there is a sweet spot around 10-15 since you can get enough kelp to hide it well while also preventing them from swimming out.
Step 4: Place a border made of blocks that blend in with the seafloor (you can go for something like stone or something you can put kelp on). Make it at least 2 blocks high, as there is a bug allowing the player to jump while on bubble columns (tested in creative), 3 if you have enough space. These are to trap the player/squid/fish in the trap while the magma blocks kill them. If you have the capability to do so, store an Elder Guardian nearby to prevent players with good gear from breaking out.
Step 5: Now blend in the trap. Make your walls look slightly more natural (like a small incline underwater) first. Then, smother the area with kelp. I mean choke the life out of it. There shouldn't be a space within 7 blocks that doesn't have a kelp seedling. Then disguise the area temporarily while you wait for the kelp to grow.
Pros:
More or less silent
Minimal resources
Automatic killing and collection, gathers food
Larger sized traps can kill boats
Players without water equipment can't see it easily until they are over it
Cons:
Requires a lot of time
Needs to be deep and well-cloaked to hide well, night vision can still spot it easily
Doesn't work well on most op faction servers, unless you are in a deep ocean, due to high quality pickaxes
Takes long enough to kill for people to obtain coordinates
Relies on target being somewhat unaware
Accidental self-harm
Slime trap
This simple trap targets slimes. All you need is some water buckets. Dig a 4x4 hole three blocks deep. Fill the bottom layer with water, so that it is all still water on the bottom. When any sized slime wanders around, it may fall into the hole. Since slimes cannot jump in water, it will not be able to escape. You can come by later and kill all the slimes, however, you must jump in then get the drops. If you are not interested in the drops, just leave them in to lower slime population. This trap is recommended on Superflat survival worlds where you can get water from village farms and easily make the hole and slimes spawn a lot.
Drowning room
Make a small room, preferably 5x5x2. Place a chest in the center of the back wall. Then put 2 blocks of sand above the chest with water behind it. As soon as they break the sand to enter the chest, the water will pour out. If you want, you could have an airlock instead of the one-way door. Have torches supporting sand in the hallway to the trap. As soon as the water comes out it will flood the hallway and burn out the torches, causing the sand to fall and trap the player even more.
Trapdoor drowning
This trap is made by digging a 2x2x3 hole in the ground, filling the middle of the hole in with water, and putting trapdoors at the top. Place pressure plates a block away from the trap in a square pattern so that, at the moment, they can't open the trap doors. Between the pressure plates and the trap, place redstone wire to open all the doors at once. When a mob walks over the pressure plates he can fall down the water, and the trapdoors will shut, forcing him to drown. At the lowest level of the trap you can make a 1x1 tunnel of water to retrieve the loot. Generally these are the most efficient types of traps because there is no lava involved to burn any loot.
Retrieval trap
A trap made with water and dirt which can kill any mob.
Create a water current that drags the mobs down under a solid block. The current will hold the mobs under until they drown. The loot from the mobs will sink, which can be collected below.
This trap is used as a water barrier to keep the mobs from swimming into another area. This requires that the floor of the body of water be easily accessible. The trap is extremely effective, but it's rather large, sucking in a 6x6 area of water.
Dive down to the bottom of the pool of water. Build up a hollow tower out of a weak material, ideally sand. The basic template is a square hole, at least 2x2. The air gap will be this size.
x = sand O = empty
O X X O
X O O X
X O O X
O X X O
Make the top flush with the surface, then empty the tower of water using a bucket. Set four TNT blocks as low as possible, then light the TNT and run.
The TNT does not have to be on the bottom. The result will be a 2x2 tower of air going from the surface to the bottom with waterfalls on all sides.
Trapping pool
This trap is designed to trap skeletons and zombies, not to kill them!
Dig out a 5x5 square.
Dig a 3x3 square 2 layer deep in the center.
Place water in each of the corners and in the middle of each side on the top, where the water isn't flowing along the top.
Lava traps
Lava traps use lava to slow, trap, or burn the target. Usually they use lava for the later, as not many mobs are fire proof. The traps here use lava as the primary component to harm the target.
Trapped Chest Lava Pitfall Trap
Build the 2 rows sticky pistons such that are facing each other and the rows are 4 blocks apart.
Attach solid blocks to the rows of sticky pistons.
If an unaware player doesn't look before climbing, they will go into the lava and burn.
Door lockdown
An emergency lock down trap ensures players can't bypass the trap redstone lock system by breaking the door. It uses an iron door as support for the initial sand block. A diagram for the completed section of the corridor can be found below.
Place the iron door in the middle of a tunnel with adequate space. Connect the iron door to a redstone lock system. Dig above the door until the area above the hall is a hollow 5x3 area. Place sand on top of the door, then place torches on the side of the sand. Repeat until the sand touches the wall. Place lava in the empty space above the sand. The only way to get through would be to unlock the redstone lock system. If someone destroyed the door, the sand would be unsupported allowing the lava to fall on them. To stop players from simply mining around the device, place lava behind the walls.
Since lava spreads slowly, it may be possible for the thief to destroy the door then quickly run to safety on the far side. To counteract this, include an airlock style sand pillar to block the path. If the thief tries to break it down, the lava will have enough time to spread and ignite him. Also, lava spreads more quickly in the Nether.
Lava door
Make a house, and right inside the front door make a pit with lava. A careless player may wander in and, whoops, lava trap.
Place a piston so it will push the target off the ledge.
Connect the piston to the pressure plate.
If the target happens to wander onto the pressure plate, the piston will come out of nowhere and push them into the lava. It is recommended to place iron bars or glass panes[upcoming] so the drops will be saved.
Lava bed
Possibly the most evil trap ever made is a bed based one. After sleeping in a bed you appear in one of the blocks immediately next to the bed (including diagonal). Sometimes though it's through a wall. If you can't imagine how that would happen, imagine a bed in the corner of a simple 3x3 house in which the corners of the exterior of the house are missing. The blocks beside the left of the bed and top of the bed are blocked because of the walls but the corner one (to the left and up at the same time) isn't blocked it's just outside. Someone sleeping here could find themselves standing in that missing outside corner in the morning. Now imagine an underground house with a lava chamber hidden behind the corner of the room like that and half slabs everywhere beside the bed on the safe side. Lava doesn't count as an obstruction but slabs do, so as far as the game is concerned that lava block is the only spot available. It looks harmless enough since you can't see the lava hidden behind the corner of the room. But after their sleep finishes they wake up in flames. The worst part is that upon dying they will respawn back at this bed...in the only block beside the bed that is open. Yes, the lava again. They're stuck. They need either water, creative mode, op's help, or to go find another server to play on.

Other traps and parts
Noob Traps
These traps work best on noobs. This is because they stand out the most.
4 Doors
This noob trap has 2 forms, basic and advanced. All you need is 4 iron doors, a pressure plate, and bedrock. If you choose the advanced form, also use a command block. To make the basic form, put a pressure plate down in the center, put iron doors on the rim (make sure they close when powered), and place bedrock above the pressure plate, high enough so the victim can go in, but not high enough for the victim to jump. When the victim goes in, he will trigger the pressure plate, which closes the doors. The bedrock is there to stop the victim from jumping. If the victim jumps, the pressure plate will deactivate. For the advanced form, do the same as above, but place a command block under the pressure plate, far enough to be unseen, but close enough to be triggered. Set the command to "/gamemode 2 @p[r=4]", which will change the game mode of the closest player that is within 4 blocks to adventure. The player is always the victim, unless the trap is triggered by a mob. If a mob triggers the trap, then the game mode of the closest player within 4 blocks is still changed. You can also use a redstone repeater to set off another command block. The second command block should have this command: "/effect @p[r=4] minecraft:slowness 60 100000", which will give the victim the "Slowness" status effect at level 60, which will completely immobilize the victim, for 100000 ticks, which will give the effect permanently, unless the victim has some milk, or has access to the "/effect" or "/gamemode" command. Also, the victim will need access to the "/gamemode" command to escape the trap, because the victim's game mode will be set to "Adventure", which will stop the victim from placing or breaking blocks. This will stop the victim from ever escaping, unless he has access to the "/gamemode", "/give", or "/tp", and "/kill", "/effect", or, if the server has the mod, "/punish". The punishment must be a one which moves the player.
(Note: If the victim sprints, he can escape this trap, unless you use the advanced form with the slowness effect)
The 4 doors trap, triggered and untriggered, basic and advanced.
The Cake Is A Lie
You need pressure plates, a cake you are willing to lose, sticky pistons, stone, obsidian, and redstone. Dig 2 blocks down in a flat area, place a sticky piston facing up, put a stone block on the sticky piston, put a ring of pressure plates around it, dig 2 blocks down and put sticky pistons facing up in a ring just outside the pressure plates, connect the pressure plates to the sticky pistons, put obsidian on the third block above the ground over the outer sticky pistons, put cake in the center, and cover the sticky pistons with obsidian. If someone tries to get the cake, the sticky pistons trap them and destroy the cake.
House of Horror (useful for griefers)
Make a fake base with walls and an attractive outside to attract potential griefers. Trap the door so through attempted exit, the victim might die through lava. If the victim tries to get out of the house early, he will realize that a dispenser revealed by a sticky piston compartment with a released lava bucket has blocked his escape through the iron door.
If the victim blunders up the stairs, he hears a small but foreboding sound and realizes that he's standing on a pressure plate hidden from his view which sets off a TNT trap. He is forced to go further up and realizes that the stairs are very long. From here on continue torturing the victim in this manner. As soon as your test subject goes in, they will get the terror of their lives!
Note: Any person entering this trap can simply break out of the house if it is made of weak materials(dirt etc.). Use materials such as obsidian or find some other way to prevent the griefer from exiting. It is best to find some way to keep him going higher and higher up and not trying to leave.
The KILL land mine
Sick of rebuilding land mines? Not any more as the land mine NEVER explodes. Plus, it can kill a player when he/she steps on the pressure plate.
You will need:
1 wooden pressure plate
1 command block.
17 cobblestone.
Always set the command to /effect @e[r=2] 7 4 7. Dig 2 blocks down and 3x3 blocks wide. Place the command block in the middle of the hole like this:
Cover the hole with cobblestone. Place the wooden pressure plate in the middle of the cobblestone square. So when a player lands on it, it will kill them!
Pros (Advantages)
They can kill a player in ONE hit.
You don't have to build a landmine again.
Cons (Disadvantages)
You may get killed when you are near (not on) the landmine by items flying down onto the pressure plate. (This can be avoided by using a stone pressure plate.)
Some servers may change the command from /effect @p 7 4 6 to /effect @p 11 1000000 5.
Alternately you can use the code /tp @p ~0 -3 ~0 which teleports them into the void.
Command Block Traps
These are quite effective traps that use command blocks.
1. Proximity Mine
Place a command block connected to a redstone clock, faster the better, and use this command /kill @e[r=10] ~ ~ ~
Any entity within 10 blocks will be destroyed. This is also good for preventing primed TNT from getting near or arrows from flying at you.
Entry Alarm
This is not so much as a trap but an alarm. If a person or entity walks over a pressure plate or tripwire which activates turns on a redstone wire which triggers a note block. You could use different sounding note block for different entries/exits if you have more than one.
Proximity Detector
There is a way to detect if someone is within a certain proximity (17-20 blocks) in Minecraft. This is extremely useful for traps. Here is a video tutorial on how to do that:
Mob-spawning-based:
This player sensor is the smallest stable silent player detector that isn't glitch based.
Put down a BUD switch made out of a sticky piston, slime block and redstone block. Next to the piston, put a diamond block, and above where the Noob will be standing and next to,(but on the same side as the diamond block) but above the redstone block, put a redstone line leading up to about 5 dispensers full of TNT. When the Noob tries to break the block with his iron pickaxe(silly Noob!) the BUD switch will activate, and you can come back to see a room full of broken gadgetry, dirt, and wool dye. Specifically, rose red. Please note that this will only work on the most inexperienced of people. We're talking first day levels of ignorance.
In the ground, alternate netherrack and sand. Ignite the netherrack and plant cactus on the sand. This very simple trap acts as a wall against hostile mobs. Passive mobs only spawn in light (They are NOT attracted to light in any way and will often despawn in the dark) and will sometimes wander into the fire. Generally the mob will then ricochet off the cactus preventing any drops from being destroyed by the fire.
Players enter from red, the turn helps hide the soul sand.
Soul sand slightly sinks the player or mobs. Using this unique property, it is possible to capture a tall mob or player. The corridor to the right will trap a player that moves onto the soul sand. The top half shows the floor setup and the bottom half shows the ceiling. Note the open block above the soul sand. Players are caught until they place a block above them or destroy a block around them. Generally the rest of the trap will have triggered by the time they react. Pressure plates can be placed on soul sand to help hide them and to provide a redstone signal. NOTE:For a kill during this process, place lava by the soul sand. May not always work if placed incorrectly.
If a repeater is in a 2 block high space, like a tunnel, you will crouch automatically as you walk over it. However, you will not crouch if the repeater is blocking the entrance of a tunnel.
Side view of tunnel entrance.
Make a 1x2 tunnel. On the floor of the entrance place a repeater. To punish players for destroying the repeater, have it as part of an inverter connected to TNT, such that when the repeater is destroyed, it activates nearby TNT.
Minecart Fall Damage Trap
There is a way to 'store' fall damage in a minecart and later have someone take that damage even though they don't actually fall a distance that would make them take damage. Here is a video explaining how to set the trap up and showing it in use:
In certain cases it may be helpful to mask the sound of TNT* or hostile mobs by creating a noisy machine. The function of the machine itself isn't important. Pistons create a fair amount of noise that doesn't travel far, however it should look like it is doing something useful. Doors can be quickly toggled making a lot of noise. You can also group many animals together to make noise. A simple BUD that uses Redstone blocks, a repeater and a sticky piston, when the normal piston is built and then removed will also constantly trigger after being updated (be warned about the lag caused by a piston that moves every 2 Redstone ticks.)
Forcefield Trap
This trap is based on the forcefield, that the mine carts create when stacked together in a small amount of space. It is possible to hide this design behind walls to push players off and kill them from fall damage / lava damage. However, this trap is very iron-costly, for it to be efficient you will need around 250 iron, and the number increases, depending on how powerful you want the forcefield to be. This does NOT work with Modloader in Minecraft or Bukkit MP servers.
Simply set up two pressure plates in front of two large iron doors. Make this entrance as ornate as possible, to fool the victim into thinking this is the entrance to your house. Place the doors sideways and place torches under them so they appear closed but are actually locked open. By doing this the pressure plates won't work. Run redstone lines from underneath the plates onto the roof of your porch to trigger two pistons. The redstone lines should have an inverter in so the pistons are extended by default. Put an anvil on each extended piston arm, and make sure there is a hole through the porch roof down to the entrance where the player stands. When the player stands on the pressure plates, the doors won't open and while they are confused the anvils will fall on them. They will either be killed or if the anvils don't fall from high enough they get injured. This trap is useful to stop thieves from staling valuable goods, and exploits the fact that people don't look up.

Next fire a ton of arrows at the dirt and tnt and build a staircase from the room to the tunnel hide the stairwell with plain stone but dig one space below the hidden doorway and one behind that into the starwell. place a pressure plate next to the hidden door and run redstone from it to the tnt in the top room. Now, when a player sets off this plate it causes the tnt to explode with the dirt, (not blasting the arrows away because of a patch) with the dirt no longer there to hold the arrows they will free-fall down at the intruder at the same power as a fully charged arrow.
P.S. It helps to have the intersecting tunnel wider then the hole itself as to reduce chance of arrows sticking into walls.
Fire Arrow Trap
This trap will rain down flaming arrows on an unfortunate player. First, make a long hallway with lava walls which look like decoration (Leave the lava open to the hallway).
Next put a pressure plate, button, lever, or whatever activation device you want. Connect it to a pulser, then to a line of dispensers filled with arrows. When the player activates the trap, they will be showered with flaming arrows coming out of the walls!
Perfect Player/Mob Trap
Dig four 1x1 holes (as shown below) into the ground and in the holes place a piston and in the middle place a pressure plate. Now all you have to do is occasionally check the trap for players and or mobs.
Key: S=piston P=pressure plate

The Trap of Eternal Imprisoning
If your mate activates this trap successfully, he is as good as banned, unless he has ender pearls.
The trap consists of any switch (pressure plate is probably the best one) and two sticky pistons. Upon activation the pistons start to repeatedly move after one another with the victim being between them. This causes the player to move so fast that even with a diamond pickaxe he/she won't be able to break free. Make sure that the space is closed.
The harder the material you use is, the better, but do note that pistons can't move obsidian.
NOTE: It is not confirmed if you can break free from a stone made trap with a diamond pickaxe enchanted with efficiency, however with 3 ender pearls, you can spam two, glitching you halfway through the block and using the last one, escape far away.
NOTE: The player will eventually starve to death, and if not, the trap may create extreme lag.
Tripwire Traps
This video is an example of several traps you could make with tripwires. There are many more ways you could sneak tripwire in to kill your victim, just think of the basic actions you would do in Minecraft, and try to sneak a tripwire somewhere in it.
Probably the simplest trap in Minecraft. Dig 1x1 holes 2 blocks deep; wait for a player or mob to fall in, and then suffocate him with gravel. Get their items out of the hole. Or, make an entire redstone contraption with pistons that release to drop the gravel!
Murder Holes
Note: This trap is designed for player sized mobs like zombies. It also does not work well on other players. Nevertheless, when done en masse in a ring around the structure being protected, it works relatively well.
Dig many 1x1 holes four blocks into the ground.. Then, make a two block high tunnel along one of the edges of the holes that runs ONE BLOCK DEEPER than the bottom of the holes. Then, put signs on the top of the holes to fool mobs into falling in. Go into your tunnel and kill the mobs by yourself while they stand in the hole helplessly.

Suffocation Tower
(Note: Only suitable for 1 block wide mob. However, a two block variant can also be created)
Make a 3 by 3 by 5 tower out of cobblestone. It should have a 1 block space inside, with walls that are 5 blocks high. Make a trapdoor floor for getting out of the tower later. You need to place an iron door in a doorway. Then place a pressure plate in front of the iron door. The mob will step on the pressure plate and will open the door for a time, long enough to let him in, but not long enough to let him out. Get to the top of the tower and suffocate the mob inside with your gravity-affected blocks. Make a tunnel outside with a staircase. Remember to close the trapdoor floor! You should be able to get up to the top of the tower, and drop sand or gravel on the mobs. Then dig the sand or gravel out, and go through your tunnel to the outside.

The Top of Hell
Warning: This trap works ONLY in the nether.
For noobs
Get a noob to go with you to the nether. Explode the nether portal. Go to the top of the nether (one block below void). Find an opening to the void and tell him the only way out is to use enderpearls. Give him a stack and make him teleport there. He will never be able to get back down.
For non-noobs
Dig underneath your nether portal and put a command block there. Place a pressure plate next to it. Type the command "tp @p[name=!<your name>] ~ 130 ~". Now wait for someone to enter!
Capture Trap
This trap can be used to capture mobs like zombies, skeletons, endermen, creepers, cows, sheep, pigs, horses and other players without completely killing them. You can then hit them without getting hurt yourself. This is how it works: Dig a 5 block deep hole in the ground, then use a sticky piston and a dirt block to close the top of your trap so nobody suspects you. The sticky piston will be very visible, so place one dirt block, and grow a tree on top of it. At the base of your hole, dig a ten block long corridor. Exit your hole. Then dig a 5 block deep trench that is parallel to your corridor, and fill in the walls and floor with obsidian or bedrock (in creative). Then, place an extra layer of obsidian/bedrock so that your corridor's wall has one block missing on the top layer. When mobs or players fall into the trench, they won't be able to escape. If you want, you can put ladders on one side, to make it look like it isn't a trap, and then once a player climbs down the ladder, you can use a sticky piston to bush one block with the ladders on it out of the wall, to that nobody can come out again, or you could use a row of sticky pistons to close off the top of the hole. Once a player/mob is trapped in the trench, you can hit their feet with a sword, a bow or your fists. You may want to include a chest with a tempting reward inside the trench, or a sign saying 'Diamonds/Emeralds Below!. You could even convince a player to trap themselves, by making a redstone switch that expels the ladder, and pushes/destroys the switch so that the player cannot flick it a second time. WARNING! THIS TRAP WILL NOT WORK ON MOBS THAT ARE 1 BLOCK HIGH, for example, spiders, chickens and small slimes.
Disarming Traps
When faced with a trap, the safest course of action is often to leave the way you came, or disarm the trigger by destroying the trap's components. Note that disarming a trap could be griefing, but if they are trying to kill you, you should defend yourself.
You can dispatch active redstone wires with the use of two redstone torches:
X = torch Y = redstone wire B= Any block
Front view:
XYX
BBB
Top view:
Layer 1:
B B
BBB
Layer 2:
X X
YYY
And then destroy the center redstone:
X X
Y Y
It will keep the positive input for both ends, but cutting the two ends off, keeping the current
on forever.
Note: Some traps make use of the 15-block redstone signal limit. Trying to dispatch active redstone wire this way may trigger traps that use this concept.
Consider the fact that the creator may be nearby. Oftentimes, the builder of a trap will be near the trap, waiting to collect his victim's possessions. If you encounter a trap, be ready for a fight.
Some texture packs may make traps easier to disarm than others. While you might accidentally walk across a pressure plate and activate a trap while using one texture pack, you may spot it instantly with a different one. It may also help to use an x-ray texture pack to spot parts of the trap that you may not have been able to see before, which should help you better understand how the trap works.
To fool the person who laid the trap in SMP, try subtle sabotage, but make sure you know the wiring absolutely. Therefore, if you want revenge unto the person who tricked you into the trap, you can leave a trace and then the person will want to fix it. Kill him once that happens.
Signs, Pressure Plates, Diamond Blocks, and Chests usually mean traps. Avoid these things in the open, in houses(Except your own) and in caves.
Aside from those tips, here are the most important rules of trap disarming survival, assuming you know where the trigger is. If you follow these rules, you may not break the trap, but in your reaction to it, you will not die.
Do not ever trigger the trap the expected way and attempt to outrun it. If that was possible, then the trap would be useless to begin with. Do not trigger it, log out and come back! You may fall in a pit or other measures designed to prevent logging out and surviving.
In the event of suspecting a trap or finding one, the first priority is to retreat the way you came. Although efficient traps just wrap around the kill zone, some traps take huge amounts of space and so are very hard to escape.
Never attempt to dig around a trap. There are many ways to wire redstone and any path you choose may or may not trigger fail-safes.
Destroying pressure plates cannot trigger a trap unless there is an update block in an inactive state next to it. This is the correct way to disarm Mojang's desert temple trap (more than a few youtubers don't seem to know about this and will creep about the chamber looting the boxes without disarming the bomb first).
Only destroy redstone that is inactive and that you safely find if you are sure there is not some kind of occasional pulse that flashes through to check that the line is functioning.
Destroy the components of the trap designed to kill you, if they are reachable and safe to destroy.
Most traps will not be simple pure redstone, instead having a complicated array of redstone or an obscure minecraft feature as a component. These have the downside of causing delay generally, but are hard to disarm.
Do not mess around with anything you are not completely sure about. This basically means that unless you have found the entire trap, do not attempt to jinx it or sabotage it.
Never attempt disarming while you are within "Danger Zone(s)" of the trap.
Lastly, keep in mind that in the real world if you were walking thru the park and you found a tripwire attached to a pipe bomb set up by some maniac you wouldn't try to disarm it yourself. You'd tell someone in authority, who would then send in a specialist wearing explosive resistant armor to disarm it. The minecraft equivalent would be informing the ops so they can send someone in full Blast Protection IV armor to deal with it. But then...where's the fun in that?...
Villager trap
A villager trap is a way to move villagers. Once they get far enough they can't go back. The villagers should walk from the right to the left:
This trap takes advantage of the feature where you can't walk through a two-high archway with soulsand in front of it.

Death on Impact
You will need these: Staple blocks, sand, cactus, signs, and a valuable block.
First create a 1-block thin wall, then make a small tunnel on the wall one block higher than the ground, this is where the valuable block goes. Then create a 3x3x24 pit right in front of the wall. Then on the opposite side, dig down 3 blocks so there is enough space for a cactus to be placed inside. Then place sand and cactus in the hole you dug, and place a sign on the top of the cactus. After that, dig another tunnel directly leading to the 3x3x24 pit and place signs on the sign on the cactus so that it goes through the tunnel leading to the pit. And then place signs so that they cover the pit. Then place sand on top of the signs so that it is level with the ground. Then behind the wall, place the valuable block in the small tunnel in the wall. Then place signs on the valuable block. Then place sand on a sign, so that its shadow is beside the cactus. then cover the behind of the wall. The result is a small building with a patch of sand in front of it, the victim will see the valuable block, break it, then is surprised that sand fell in front of him, and then falls on the ground and dies of fall damage, allowing you to take the loot.
House of mobs
This is a really simple trap to make. This can work on PE LITE, or for more danger, PE (not lite, but instead the paid version). All you need to do is make a fairly large house (doesn't matter how high), and then make a pit 3 blocks deep. Now, just block up the top with the material around on the ground (or wool, if you prefer), and when someone goes to your house, it is likely that due to the dark pit below, they won't be able to sleep in their bed, or will be blown sky high by creepers.
Diamond death tower
This is another easy trap to make. Create a 3x3 tower at least 24 blocks high out of cobblestone. At the top, grab loads of diamond ore, block or it could just be some other rare and valuable material. You need to make this a 4x4 area, so that there is a little ledge for you to stand on. Then, at the bottom, make a pit 3 blocks deep and about 5 blocks from the tower. You now need to put out a chest and fill it with the dirt you just got from the pit. Then get yourself some sand/gravel and wait at the top.
The result:
Now, when your victim sees your precious diamond, he can't help but run into the pit, finding himself stuck, and will see a sign, next to the chest saying: use these blocks to get to the top. He will grab the blocks and go in, starting to hop up, and up, and up. At the top, you will then start dropping your sand/gravel down the chute, and then it will fall on him, and they will suffocate.
An alternative is to fill the chest with sand, and you stand at the bottom, and when they hop up, you destroy the sand and the pile comes down, preventing him from reaching the top, and when he runs out of material, kill him with a sword.
Simple Hole Trap: The Pocket Edition concept of imprisonment
This is the simplest trap of all time: Dig a hole 2-3 blocks down. Mobs or players will fall into the hole. Players might dig out, but you can detain and kill them while they are trying to kill them. Mobs cannot dig at all, so you can hit them from above and kill them.
Feet Hitter: Kill your enemies with impunity!
Build a structure, but with NO BOTTOM BLOCKS!! That way, when mobs try to get to you, their feet are exposed, and you can feet-hit them to death. Easy peasy. Players are more difficult, but you can still deal significant damage.
Dungeon Death
Locate a dungeon. Then stay there. when your friend finds you, they will find an empty dungeon- filled with zombies !! Your friend's death, 100% accurate.
What the [expletive]?
This is a weird trap. Build a house of TNT, and make a TNT line to some unseen distance. Put a wood block, light it on fire. ( Wood substitute redstone )> After a while, the TNT ignites, and BOOM!! TNT ignites. The person inside the house should think "____" and die. Even if they escape, the amount of TNT blows them sky-high.
Death Temple
First,make a 5x5 area made with some kind of sandstone,chiseled works well. Then,add a 3 block high wall. In the wall that is opposite to the entrance,put a diamond block. Then put a sign behind that diamond block and stack a bunch of other signs up to the top of the wall to hold up sand. (Make sure to cover most of the signs behind the Diamond Block so nobody sees it!) When the player mines the block,they will suffocate and die. This way you can get their loot AND your diamond block. Pretty good,huh? You could always use Gold or Lapis Lazuli blocks.
Tower o' Ore
ATTENTION! VALUABLE ORES WILL BE LOST. THIS IS GOOD FOR RICH PEOPLE!!
First make a tower about 3 by 3 about 20 blocks high with a watchtower at the top and TNT in the middle and ladders on the side.
Then you put a block of any ore at the top and say,"Go get it, I'll be up there watching you."
Then you watch him go up the tower and right when he is about to mine it you light the TNT and run.
