FastStair+

FastStair+ is a hyper-casual Chrome extension that dares you to climb 100 stairs with full effort — no breaks allowed. Tap the control button to climb a step; repeat 100 times. Simple controls, brutal timing: push too hard and you’ll fall. The whole run is built for ultra-short, intense play sessions — amazing under 10 seconds for top players.

Perfect for quick challenges and friendly competitions, FastStair+ includes global leaderboards so you can aim for the #1 spot. It’s easy for anyone to pick up but tough to master: one-button gameplay, instant restarts, and addictive risk-versus-reward pacing. Take the challenge, improve your run, and see how you stack up against players around the world.
