Not Tetris is a variation of Tetris plays rather similarly to Alexey Pajitnov's classic puzzle game, but instead of making complete horizontal lines with the tetrominoes the objective here is to fit as many blocks as you can into the well before it reaches the top of the screen. Players can rotate blocks with the A and S key, but when one tetromino touches another it will then be at the mercy of physics and gravity.

Only the Windows version is available for download, but if you are a Linux or OS X user you can try downloading the LÖVE engine (used to develop Not Tetris) for your operating system and try running the source code. There are a couple of audio issues in this build, but Maurice is already hard at work on a sequel that resolves all of the problems and will include the cutting of pieces when a line is ninety-percent full.
