YoHU Sky Stack
Free · no download · phone, tablet & desktopYoHU Sky Stack is a one-tap stacking arcade game. A building floor slides back and forth at the top of the tower — tap to drop it. Land it perfectly aligned to keep your full width and build a combo; any overhang gets sliced off, so the tower gets narrower with every miss.
Climb through level after level as the speed ramps up and the sky shifts from day to sunset, night, aurora and outer space. Simple to pick up, hard to put down — chase that perfect run and a new high score on desktop or mobile.
