Tower Stack is a one-tap timing game about building the tallest skyscraper you can. A crane swings a block back and forth above your tower — tap to drop it. Land it flush and the tower grows clean; land it off-center and the overhang is sliced off and tumbles away, leaving you a narrower block for every floor after. Miss completely and the run is over.

The magic is in the perfect-drop streak: align within a hair's width and you keep your full block, build a combo, and — from two perfects in a row — your block actually grows back wider. Skilled players recover from a sliver-thin tower to a full-width one, which is where the high scores live.

How to play

Tap anywhere (or press Space) to drop the block from the swinging crane.
Only the overlapping part of your block survives. The rest is sliced off.
Perfect drops ring gold, chain a streak, and regrow your block up to full width.
The crane swings faster and wider as you climb. Every 10 floors, the sky changes color.
Your score is your floor count — one number, straight onto the global leaderboard.

Tips from the leaderboard

Watch the dashed guide lines falling from the tower's edges — drop when the crane block is between them.
Tap when the block crosses the center of its swing, where its horizontal speed feels most predictable.
If your block gets thin, stop rushing. Two calm perfects rebuild your width faster than five hasty drops lose it.
