Alpha v1.1.1, also known as Seecret Saturday, is the tenth and final seecret update, which is added sneaking, new paintings and fishing rods. It was released with server 0.2.1 on September 18, 2010, and is the only Seecret Saturday update; all other nine seecret updates were released on Fridays. This version is notable for the gray screen bug. This code would set the display's gamma and contrast values to zero, resulting in the screen going completely gray. This version also took a very long time to download due to a sudden influx of players attempting to access the download server at once, and was available for just 205 minutes.
- Have no use.
- Are stackable.
- Added the ability to change mouse sensitivity
- Added sliders to change volume of sound and music
- Two paintings have had their textures changed to their modern versions.
- Option to toggle the debug menu in the options has been replaced with the F3 key. F3 + S reloads all web-loaded resources.
- Smoother day-to-night and night-to-day transitions.
- 2 bugs fixed
- Infinite snowball exploit fixed where snow blocks (requiring 4 snowballs) would be crafted then broken, producing 4–6 snowballs back.
- Solid snow blocks now only drop four snowballs.
- Despite this version being available for several hours, considerably longer than other archived versions such as pre-reuploads of Beta 1.1, there were no known archives of it. An archived copy was not found until June 25, 2021, when Twitter user LunaSorcery provided an archived jar file.
- There was a bug with crouching that caused the outer layer of custom skins render as if the player wasn't crouching. 
- This version is identical to Alpha v1.1.2, with the exception of the grey screen. The grey screen was caused by one line of code, and this one line was removed in a1.1.2.
