How high can you climb?
Sky Stack is a one-tap 3D tower-stacking game built for quick, addictive play. Tap to drop each sliding block onto the tower. Land it flush and you score a PERFECT combo with a rising musical note and a burst of particles. Miss, and the overhang gets sliced off - your tower gets narrower and the challenge climbs with you.
The higher you go, the more the sky shifts through a ladder of colors, turning every run into a little journey upward.
