Stack Tower
Casual
Stack Tower is a free timing game about building the tallest tower one sliding block at a time. Drop each block on the one below; whatever hangs over the edge is sliced away, shrinking your platform. Perfect drops flash, regrow your block, and chain into rainbow combos as wind, fog, and golden blocks join the climb.

A block slides back and forth above your tower — tap, click, or press Space to drop it. Overhang gets cut off, making the next drop harder. Perfect alignment keeps your full width and builds a combo. The run ends when a block misses entirely.
Tips & tricks
Watch the leading edge of the moving block, not its center, and drop a hair early — reaction time eats the difference. Combos regrow width, so chasing perfects is defense, not vanity. When wind arrives at higher floors, time your drop at the swing's slow turning point.
