STACKO

STACKO is a fast, hypnotic 3D stacking game. One tap drops the moving plate onto the tower — line it up clean and keep climbing. The twist: in VANISH mode the plate gets a little smaller with every floor. The higher you go, the tighter the target. No chopping, no second chances — miss the edge and the whole tower topples. And every day, DAILY gives the entire world the exact same tower. Same speeds, same rhythm, three tries. Post your score and settle it — your friends play the identical run, so there are no excuses. FEATURES • One-tap, one-more-try arcade gameplay • VANISH mode — the shrinking-plate challenge that gets harder the higher you climb • DAILY challenge — one shared tower for everyone, 3 tries, a brand-new tower at midnight • 8 unlockable neon themes — Neon, Holo, Magma, Glacier, Royal, Zen, Abyss & Cosmos, from Rare to Legendary • Earn coins as you stack and spend them in the shop • Beat your best and climb the leaderboards • Smooth, glowing 3D visuals with a satisfying stack-and-snap feel • Plays offline — no connection needed Simple to pick up. Nearly impossible to put down. How high can you stack before it all comes down? STACKO is free to play and supported by ads. You can watch an optional ad to continue a run or double your coins, and a one-time "Remove Ads" purchase turns off the banner and between-game ads.
