Stack

A block slides back and forth above the tower — tap (or press Space) to drop it. Whatever hangs over the edge gets sliced off, and the next block is only as wide as what's left. Land a perfect drop to keep your width, and chain three perfects to grow back. Miss the tower entirely and it's over. How high can you go?

Keyboard: Space/Enter/↓ drop · P pause — or tap anywhere on touch screens
