Tetris DX

Tetris DX is a Game Boy Color game that is backward compatible with the original Game Boy.
It features battery-saved high scores and three player profiles. It has a new single-player mode against the CPU and also features two new modes of play. In “Ultra Mode”, players must accumulate as many points as possible within a three-minute time period. In “40 Lines”, players are timed on how quickly they can clear 40 lines of play.
