How to play Sky Stack 3D

A glowing block slides across the top of your tower. Tap to drop it. Any part hanging over the edge breaks off and tumbles away, so the next block is only as big as the overlap.

Land a block almost exactly on the one below for a Perfect. It keeps its full size.
Three Perfects in a row make your block grow back a little.
Every 10 floors you rise into a new sky: sunset clouds, the aurora, then outer space.
Blocks speed up as you climb. Miss the tower completely and the round ends.
