TETRIS for the Jupiter Ace.
A 16K RAM pack is required to run this game on a standard ACE.
A random sequence shapes composed of four square blocks (called ACERADS) each fall down the playing field. The object of the game is to manipulate these acerads, by moving each one sideways and rotating it by 90 degree units, with the aim of creating a horizontal line of blocks without gaps. When such a line is created, it disappears, and any block above the deleted line will fall. As the game progresses, the acerads fall faster, and the game ends when the stack of shapes reaches the top of the playing field and no new acerads are able to enter.
