Upblock: Stack Blocks

Tap to stack blocks and build a neon tower. In Upblock, every drop tests your timing: line up the sliding block to keep it whole, or lose the overhang as it is sliced away. Each smaller landing makes the next tap count even more. ONE TAP, ANOTHER FLOOR Drop each moving block onto the one below. Aim for a clean alignment, keep your tower wide and see how high you can climb. Short rounds make it easy to try again and chase your own high score. THREE BOOSTERS FOR THE NEXT DROP Undo takes back your last block, even after a miss. Stacker places perfect floors for you. Slow-mo slows the moving block to help you line it up. Each booster can be used once per game. 14 WAYS TO STYLE YOUR TOWER Choose from 8 classic skins and 6 animated neon skins: Neon, Electric, Hologram, Synthwave, Circuit and Plasma. Earn gems as you stack and spend them on boosters and skins. A FRESH WEEKLY CHALLENGE Compare scores on weekly and all-time leaderboards. Start another run, improve your timing and work towards a higher score. One tap. One more floor. Stack to the neon sky. Contains ads and optional in-app purchases.
