How to Play
- Drop blocks: tap (or press Space) to drop the sliding block onto the tower.
- Trim the overhang: any part hanging past the block below is sliced off and falls away, so the next block is smaller.
- Go for perfect: land it almost exactly on top for a PERFECT bonus. Two or more perfects in a row slightly regrow the block.
- Do not miss: drop a block completely off the tower and it is game over. Tap to restart instantly.
- Speed up: blocks slide faster as the tower grows.

Blocks slide across the top of the tower from alternating sides. Tap the screen, or press Space or Enter, to drop the block. Line it up with the block below to keep it wide.
