Includes two modes, Classic Mode and Puzzle Mode. Classic mode resembles gameplay from Tetris (Game Boy). Puzzle mode involves clearing lines to get a professor to the bottom of the playing field before the spiked ceiling comes down to crush him. Also included is Edit mode, which is a level editor for creating Puzzle Mode levels, and VS Mode, which is a two-player version of Puzzle Mode (the Game Boy version requires the Game Link Cable for this mode).
