Tromp

Tromp is a clone of Tetris for the 1989 Obfuscated C Code contest. Like most versions of the game, the objective is to orient falling blocks of four squares so that they form an unbroken horizontal line in the playfield. When a line is formed, that row is removed from the board. If the board is filled to the top, the game is over. The objective is to survive as long as possible and earn a high score.
