Creative

Creative mode is one of the many Game Modes in Minecraft. It is currently only playable in the Classic version and will be released for the Alpha version some time soon.

Players are given an infinite amount of each block to build and no health or damage to worry about. Taking advantage of this, players can create large constructions such as castles, roads, buildings and skywalks, along with forms of artwork. A chessboard or giant picture rarely goes amiss on a server. Not only have users designed buildings, Pixel Art, and caves, but also mini-sports. Using the current in-game features, users have put them to clever use. An example of a Minecraft sport is Spleef.
