Gurn is a runner you play with your face. No taps. No swipes. You jump by opening your mouth, change lanes by tilting your head, duck by tucking your chin, and float by puffing your cheeks — all read live by the front camera. The faster it gets, the more contorted your face has to get. And the clip is the point. While you play, Gurn records a split-screen of your face next to the run and auto-edits the wreckage into a clip you can post in one tap — with the game's sound or muted so you can drop your own. The runner is just the excuse to manufacture something worth sharing. What you get - A runner controlled entirely by your expressions — no buttons on screen - One-tap capture and share: face + gameplay, auto-trimmed, ready for TikTok, Reels, or your camera roll - A daily challenge everyone runs on the same seed — honest leaderboards - Clip-visible cosmetics you earn as you play — trails, finales, and outfits - A deadpan voice that calls your runs like nobody asked - Or play with touch — a full touch-control mode, with its own leaderboards The rules we won't break - Your face stays yours. Face tracking runs entirely on your device — nothing biometric is ever stored or sent anywhere. - You can't buy your way up the board. Nothing purchasable touches your score, speed, or rank. Cosmetics are cosmetics. - Sharing is never gated. Every run exports in HD and posts in one tap; clips carry a small Gurn wordmark — that's how people find the game. Free to play — every run exports in HD and shares free. The optional extras are all looks and laughs — cosmetics you can earn with coins or grab in a Starter Pack. Nothing you buy touches the leaderboard. No subscription, ever. Bring a face. Leave with a clip.
