The main game is viewed from the front of a three-dimensional playing well. Pieces descend into the space, and the player moves or rotates them so that completed layers or lines are formed and cleared.

Modes include 3-D Tetris, a conventional 2-D Tetris-style mode, and Puzzle mode. Progression is based on clearing formations and surviving the increasing demands of the selected mode rather than on a story or character system.

Plan the piece's final position before it reaches the lower part of the well. Check depth as well as the visible front face, because a placement that looks correct from one angle can leave gaps behind it.

Keep the stack as level as possible, avoid isolated holes, and use the simpler 2-D mode to become familiar with the game's piece handling before attempting more complex three-dimensional placements.
