How high can you stack?
StackUp is a one-tap arcade game. A block slides back and forth: tap to drop it on the tower. Whatever hangs over the edge is sliced off, so your next block gets smaller. Land it perfectly and it keeps its full width.
SIMPLE TO PLAY, HARD TO MASTER
• One tap, nothing else to learn
• Perfect drops keep your block wide and chain into combos
• A live indicator tells you when your best score is within reach
5 DIFFICULTY MODES
• Chill: bigger blocks, slower pace
• Classic: the original balance
• Hard: faster and narrower
• Insane: for experts only
• Zen: no game over, stack forever
Hard, Insane and Zen unlock as you progress.
