What is it?
Your runner goes on its own — one button makes it jump. Like Geometry Dash, it is all about rhythm and timing.
Everyone runs the same course each day, racing the ghosts of the #1 player and your own best. Open a friend’s challenge link to race their ghost.
One-Button Dash is an auto runner game: you start at 7 m/s and speed up every 140 m, and how long you hold sets how high you jump. Spikes, saws, pits and walls are built from a seed, so courses never end, and after a crash you can practise that section. It suits anyone browsing jumping games online for a quick run.
One-Button Dash is an auto-runner with a single input. The runner moves on its own at 7 m/s and gains 1 m/s every 140 m until it hits 14 m/s at 980 m; the ⚡ figure at the top left is that speed over the starting speed. A press starts a jump, and holding keeps gravity weak for up to a quarter of a second, so each jump's height depends on how long you hold. Distance is the score, kept to 10 cm.
Spikes, saws (low, high and moving), pits, walls, stairs and one-way platforms are generated from a seed, so a course never runs out and a seed always builds the same course. Today's Course takes its seed from the UTC date, so everyone gets the same layout that day. After 150 m the current rules group obstacles into themed zones that end in a short rest, with stars where a higher or more exact jump is needed.

How to play
- Pick 'Practice Run' to start without an account. Retry the same course or challenge a friend’s ghost.
- When you see 'Press to start!', press Space, ↑ or W, or tap the screen.
- Use the same button to jump. Hold for a higher jump; give a quick tap to pass under saws.
- You speed up as you go. Touching spikes, saws or the side of a wall, or falling, ends the run.
- After a run, press Space, R or Enter to retry the same course. Friend challenges need no account; saving a world ranking on Today’s Course requires GameNow sign-in.
Modes
- Today's Course
- One course per UTC day, the same for everyone, with a world ranking and a reset countdown. The #1 run, if someone else holds it, races you as a gold ghost and your own best as a sky-blue one.
- Practice Run
- A random seed each start. 'Same course again' keeps it, 'New course' rolls another, and your best on that course runs as a ghost. Not ranked.
- Friend challenge
- A finished run sent as a link. Your friend runs the same course against your pink ghost and a pink line at your distance; no account needed, valid for 7 days.
- Ranking challenge (⚔)
- The ⚔ beside a ranking entry, or the link shared after saving, loads that record as a ghost. On today's course your run is still ranked; older days are not.
- Practice last section
- Offered after a crash: after a 3-second count you restart on ground before that obstacle, from a near or earlier point. It never changes records, rankings or goals.
Good to know
- Today's Course is the same worldwide each UTC day; ghosts of the #1 player and your own best run with you.
- Retrying a practice run keeps the same course. Starting a new practice run from the menu creates a new course. Practice scores do not enter the world ranking.
- The run pauses by itself when you switch windows or open this controls window.
- A/× or RT/R2: jump (hold for height); START: pause/resume.
