One-Thumb Stunt is a free arcade game you play with a single tap. A bouncy blob on one wheel rolls through an endless gauntlet of gaps. Every few seconds the rules mutate: low gravity, bouncy walls, crosswind, gravity flips, shrinking gaps, speed-ups. A banner warns you one second ahead, so you can adapt. Later the changes get faster and start to stack.
Tap, click or press Space to hop. A tap always pushes against gravity. Skim the edge of a gap for a near-miss combo and bonus points. Tap again right after dying to retry instantly.
The daily run is the same course for everyone that day. After a run you can copy a link that challenges a friend to beat your score on the same course. Everything works without an account.
