Arcade timing
Every block is about timing, not grinding. The challenge comes from staying precise as the tower narrows and your margin for error disappears.

Browser Arcade Game
Mountain Stacker is a simple timing game with real leaderboard pressure.
The rule set is clean: place each moving slab as accurately as possible, keep the tower alive, and push your score higher before the stack gets too thin to recover. It plays instantly in the browser and tracks high scores through the built-in leaderboard.
Leaderboard runs
Set a name, post a run, and compare your height against the best scores on the site. The page also keeps a local best so you can track progress immediately.
No install needed
Mountain Stacker runs in the browser with keyboard controls and fullscreen support, so it works like a fast arcade detour inside the main LetsDecide.games site.
How Mountain Stacker works
- 1. Start the round. Press Enter or click the game to begin the first pass.
- 2. Place each slab. Hit Space when the moving block lines up with the tower.
- 3. Survive the trim. Missed edges fall away, which makes the next placement tighter.
- 4. Chase a higher score. When the run ends, restart and try to beat your best height.
