About

STACKO

Features
Read full description

Tap. Drop. Perfect. STACKO is a satisfying 3D stacking game: one tap drops a glowing block onto your tower, and a clean drop snaps into place with a chime that climbs higher with every perfect in a row. In VANISH, chain perfects and your tower fights back: from your third perfect drop in a row, every perfect grows your block back, so one great streak can rescue a run. THREE WAYS TO PLAY • VANISH: the signature mode. The block gets a little smaller every floor. No chopping: miss the edge and the tower topples. • DAILY: one tower for the whole world, new every day. Same speeds, same rhythm, 3 tries. Compare scores with your friends. • CLASSIC: the timeless chop-and-stack, where whatever overhangs is sliced off. Unlocks at level 3. A REASON TO COME BACK • Level up with every run and unlock the CLASSIC mode and new themes • 3 daily missions, with a bonus for clearing all three • A daily gift that grows across a 7-day calendar • Streak bonus coins for playing day after day • 24 achievements to unlock • A marker on the tower shows your record, so you always know how close you are • Game Center leaderboards 20 THEMES TO COLLECT Every theme changes the blocks, the sky and the mood, from Starter to the new Mythic rarity. Buy themes with the coins you earn, unlock them by levelling up, or get the Mythic Diamond, Aurora, Galaxy and Starlight themes in a pack. MADE FOR QUICK BREAKS • One-tap controls and quick runs • Plays offline, no Wi-Fi needed • Smooth, glowing 3D with sound and haptics that react to every drop • Pause any time; the game also pauses itself when you leave the app • An optional daily reminder, off unless you turn it on • No account or login ADS AND IN-APP PURCHASES STACKO is supported by ads and optional in-app purchases. • Rewarded ads are always your choice, and each offer says exactly what you get: continue a run, double a run's coins, double the daily gift, one more DAILY try, or 40 coins in the shop. • A full-screen ad may appear now and then between games, never during a run. • Remove Ads removes all ads for good; after a reinstall or on a new device, tap Restore Purchases. The rewards that normally need an ad are given without one, and you also get one continue every run, double coins and a double daily gift. In-app purchases (all optional; prices are shown in the app): • Remove Ads: no ads, plus the perks above • Starter Pack: Remove Ads, the Starlight theme and 2,000 coins • Legends Pack: the Diamond, Aurora and Galaxy themes • STACKO VIP: Remove Ads and every theme, including themes added in later updates • Coin packs: 1,000, 6,000 or 15,000 coins Coins are also earned simply by playing, and purchased coins never expire. Nothing for sale is random: there are no loot boxes. Restore Purchases is in the shop and in Settings. How high can you stack before it all comes down?
