The game Tetris is one of the things, every programmer has written (or will write once). And, as you probably guessed, I’m not an exception. However, creating a simple tetris game is not exactly exciting, so I’ve decided to add something unique. My version of Tetris does not have great graphics, sounds or music, interesting bonuses, lemmings, or almost naked girls in it, but it has an evil artificial intelligence. If you have played Tetris for a longer time, you surely had the feeling that the game chose the worst possible pieces, and you were probably wrong. In this version, you would be right.

The principle is simple enough - the game contains an evaluation function that adds “score” for each gap closed from above (and a special bonus for gaps closed from all sides) and chooses pieces that lead to highest scores, with simple planning based on the MiniMax algorithm.
