How to Play

Press Space or tap to drop the moving block. Align it perfectly with the block below. Off-center parts get trimmed away!

Objective

A block swings horizontally at the top of the screen. Drop it by pressing Space or tapping. The block is trimmed to match the overlap with the block below. Perfect alignment keeps the full width and builds a combo. The game ends when a block completely misses the one below. Four difficulty levels (Easy/Medium/Hard/Expert) affect block width and speed. Three modes: Classic (endless), Level (clear 30 floors), Precision (95% perfect rate).
