How to play

• A block slides back and forth above the tower. Tap anywhere to drop it; on a computer, click or press Space or ↑.
• Whatever hangs over the edge is cut off, so the tower gets narrower. Drop it right on top and it snaps into place and wins back a little width.
• Build 25 floors to clear the level. A block that misses the tower completely costs a life; three misses end the run.

Each level gets one run a day, and everyone gets the same blocks, so you can compare scores. Hard starts narrower and slides faster. P pauses. New runs arrive at midnight.
