Stack Tower is a one-touch precision arcade game built on a single, instantly satisfying idea: a block slides left and right above your tower, and a single tap drops it. The overlapping part becomes the new floor; everything that hangs over the edge is sliced off and tumbles away. Each sloppy drop trims the block narrower, so the higher the tower climbs, the less room for error remains. Nail a perfect drop — block dead-center — and width is regained while a perfect streak grows. A live combo multiplier rewards focus: 5, 10, and 20 perfect drops in a row push the coin multiplier up through ×2, ×3, and ×5. Every five floors the tower shifts into a new color tier, and blocks speed up as height increases.
A block slides horizontally above the top of your tower. Tap to drop it — the slice that overlaps the block below becomes the new floor, and the overhang is cut off and falls away. A perfect drop (dead-center) loses no width, regains a little, and extends the perfect streak. Miss the tower entirely with no overlap at all and the run ends.
Two modes are available. Classic is endless — climb as high as possible, one full miss ends the run. Daily Challenge is a seeded run identical for every player on the same date, with its own separate best score. Three Daily Missions refresh each day; clearing all three fires an extra +50 coin bonus. Coins can be spent in the Shop to unlock four extra themes — Sunset, Candy, Mono+, and Magma — each restyling the tower's palette and background.

Chaining perfect drops — landing the block dead-center — builds a streak that raises the coin multiplier to ×2 at 5 perfect drops, ×3 at 10, and ×5 at 20. A non-perfect drop resets the streak.

Three Daily Missions roll over at midnight each day. Clearing all three awards an extra +50 coin bonus on top of the normal payout.
