Sky Stack

Build a tower up to the sky, one block at a time!

A block slides back and forth. Tap to drop it on your tower. Any part that hangs over the edge gets cut off, so your next block is smaller. Line it up just right for a Perfect, and get three Perfects in a row to grow your block back.

Easy to learn, hard to master. One tap is all you need. How high can you stack?

• One-tap controls: works with touch, mouse or keyboard
• Bright colors that change as your tower grows
• Quick rounds, great for a short break
