Rather than moving your piece back and forth, Torus is played by rotating the ring-shaped base that your piece will fall upon. The [left] and [right] arrow keys rotate the base, while the [up] and [space] keys rotate the piece, and the [down] keys drop the piece faster ([WASD] can be used as an alternative). As in "old-fashioned" Tetris, your goal is to drop pieces that form complete lines, which are removed from play. Unlike old-fashioned Tetris, Torus likes to sneak in irregularly-shaped pieces, like the tetrominoes you're used to with an extra or missing -omino. Traditional mode lets you play at increasing speeds until you reach the top of the level. Time Attact [sic] mode challenges you to score as many points as you can in three minutes, and Garbage mode requires you to reduce the random stack of blocks to a height of three as quickly as possible.
