DIFFICULTY
How to play
Drop: tap the tower, the ⬇ DROP button, or press Space. The block falls straight down from the crane.
Any part hanging over the block below is sliced off and falls away — your tower gets narrower with every sloppy drop.
Land within a hair of perfect and the block snaps into place: your combo grows, you bank bonus points, and the next block regrows a little. Miss entirely and the run ends.
Watch for pattern beats as you climb: gold bonus blocks arrive wider, and every tenth floor is a moving platform that slides while you aim.
On Architect and Skywright, high-altitude wind gusts push the falling block sideways — read the wind arrow at the top and drop early into the gust.
Score = blocks stacked, plus combo bonuses for perfect drops. One miss ends the run.
About Tower Stacker
Tower Stacker is the purest test of timing in the arcade: one sliding block, one button, and gravity. Every drop is a small negotiation between greed and safety — the overhang you leave is sliced away forever, so a tower is really a record of every mistake you made on the way up, narrowing as it climbs.
The perfect-drop combo is what separates a decent tower from a great one. Perfects don't just bank bonus points — they regrow the block, buying back the width your earlier mistakes cost you. Higher tiers add high-altitude wind that shoves falling blocks off line, and pattern beats like bonus-wide blocks and moving floors keep the climb from ever becoming a metronome.
Quick tips
Drop a fraction early — the block keeps drifting with the crane's momentum in your head, not on screen. Trust the aim guides.
After a slice, take one safe centered drop to reset your rhythm before chasing perfects again.
On windy tiers, aim upwind: let the gust carry the block onto the tower instead of fighting it.
