How to play
Updated 2026-09-21How to play
Start and place each moving block when it aligns with the tower. A very small error preserves its width; larger overhangs fall away.
Controls
Click, tap, or press Space to place. Blocks move sideways automatically; no dragging is needed.
Scoring and ending
Each placed layer earns 1 point. No overlap, or a remaining width below 10 pixels, ends the run. Movement gradually speeds up.
Practical tips
Use the tower edge as a reference. Wait for another pass rather than dropping a visibly misaligned block.

Snake
Steer an automatically moving snake toward red food. Each bite makes it longer and gradually faster, leaving less room for mistakes.
