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.
