Multiple versions of Tetris

This paper investigates different versions of the game Tetris on their playability. It does so by utilising an automated Tetris controller ‘TetNet’ that uses Genetic Algorithm to create an evolving Tetris AI (Artifical Intelligence). Using ‘TetNet’ several hypotheses will be formed on the playability of different Tetris games. By making use of existing theorems and newly defined theorems, a handful of proofs will be given for the hypotheses formed earlier. This will be done by creating infinitely playable strategies for each version of a Tetris game, and drawing out cycles according to the playing strategies.
