The playfield is a rectangular pit viewed from an angled top-down perspective. Pieces fall into the pit, and the player moves or rotates them so that each layer is filled without gaps.

Completed layers disappear and increase the available space. The game becomes progressively more difficult as pieces fall faster and the player must judge depth, rotation, and the shape of the existing stack. The objective is to survive as long as possible and achieve a high score.

Plan several placements ahead instead of reacting only to the falling piece. Keep the surface of the stack as level as possible and avoid creating deep holes that can accept only a few shapes.

Use rotations to preserve flexible spaces near the center of the pit. When the stack becomes uneven, prioritize clearing a layer over setting up a risky combination.
