Tap Sprint

How to play

• Pick a race length (10, 30 or 60 seconds) and press Start. Run when the countdown reaches zero.
• Press ← and → one after the other. Each step speeds you up, and you slow down when you stop tapping. A steady 10 steps a second holds about 10 m/s (36 km/h). The top speed is 13 m/s.
• Pressing the same arrow twice in a row is a stumble and costs you speed. Holding a key down doesn't count as steps.
• Your score is the distance in meters when the timer runs out. Your best for each race length is saved in this browser and shown as a yellow flag on the track.
• A run good enough for the Top distances board (one for each race length) asks for a name and an emoji or photo to save it. Names and pictures are shown publicly. You can also save any other run with Save to leaderboard.
• Scores are checked to keep the board fair: every press is timed and sent with the score, and the server replays the race to work out the distance itself. Races run faster than a person can tap (over 20 presses a second), with a rhythm too even to be human, or finished sooner than the clock allows are refused.
• On a phone or tablet, tap the two arrow buttons at the bottom corners with both thumbs.
• Keys: ← → or A D run, Space starts, 1–3 choose the race length, F fills the browser window with the game (Esc to leave).
