Tetris Variants
Several Tetris variants exist. Some feature alternate rules and pieces, and others have completely different gameplay.
A popular variant called "The Grand Master" eventually becomes so fast players have to use every second of time optimally, and it even has a mode dubbed "Invisible Tetris", where the blocks are only shown when falling – then finally revealed when the game is over.
Because of its popularity and the relatively simple code required to produce the game, a game with nearly the same rules as Tetris is often used as a hello world project for programmers coding for a new system or programming language. This has resulted in the availability of a large number of ports for different platforms. For instance, µTorrent and GNU Emacs contain similar shape-stacking games as easter eggs.
