Block Stack
Move and rotate falling blocks to fill and clear lines!
←/→ move, ↑ rotate, ↓ soft drop, Space hard drop — or use the touch buttons. Filling the top ends the run.
How to Use
Rotate and move falling colorful blocks to fill complete rows. Clearing multiple rows at once scores more. The run ends when a new piece cannot spawn. Best score is saved locally.
