How high can you build?
STACK: Tower Builder is a minimalist one-tap arcade game about timing, precision, and the irresistible pull of one more run.
TAP TO STACK
A block moves above your tower. Tap to drop it. Any overhang is sliced away, making the next placement smaller and every decision sharper.
CHASE THE PERFECT DROP
Center a block to keep your full platform and build a perfect streak. Stay calm as the tower rises and the margin for error disappears.
UNLOCK YOUR STYLE
Earn gems as you play, complete 18 awards, and unlock colorful tower skins. Track your best score, perfect drops, play time, and more.
