Geometry Run is a free online rhythm platformer inspired by classic one-button games. You control a square that auto-scrolls through obstacle courses — all you do is tap to jump. Time your jumps to dodge spikes, leap over gaps, and land on platforms across 10 handcrafted levels that ramp from gentle to nearly impossible.
Each level scrolls at a fixed speed synced to a beat. Your square obeys gravity and can jump once while on the ground. Hit a spike or fall into a gap and you restart instantly. The further you get, the faster levels scroll and the tighter the obstacle spacing becomes. Earn up to 3 stars per level based on how few attempts you need.
Tap the screen, click, or press the Space bar to jump. Your square moves forward automatically — your only job is to time jumps to avoid obstacles. Each level gets progressively harder with new obstacle types and faster speeds.
Yes. Geometry Run is completely free, runs in your browser, and requires no download or account. It works on desktop and mobile devices.
There are 10 levels, each with a unique name and difficulty. Level 1 "First Steps" is beginner-friendly, while Level 10 "Impossible" is an extreme challenge designed to test even the best players.
