Easy to learn. Hard to master.
Three rules are all you need — the depth comes from your nerve.
- Tap to drop. A block glides across the sky — tap anywhere to release it onto the tower.
- Land it perfect. A flawless landing keeps your full platform and builds big combos.
- Mind the overhang. Every miss trims the block. Precision keeps your tower alive.
