Pedal, lean, build a track, and see how far your rider makes it.
Landing in the middle of a 360, tail whip, bar spin or superman is a crash. On a phone or tablet the buttons on screen do ↑ ↓ ← → and Z (turn round); the two small ones on the left restart from the checkpoint and from the start.
Best = completed every star fastest; otherwise most stars, then furthest right. Hidden ghosts are still recorded, so the replay viewer keeps working.
Off (the original game): any touch of the head on track, platforms, shapes or balls is a crash. On: a touch slower than this speed (relative to what it hit, in units per step; the rider's top speed is around 10) is just a solid bump, so the rider can nudge a ball with their head or rest against a wall. Faster hits still crash. Wheels and the bike are unaffected.
Press R (or the Replay button) in play mode. Space play/pause, ← → step a frame (Shift = 10), Esc close.
The track you have open goes to the server and joins the random rotation on the homepage, where everyone races it. You must finish it yourself first: restart from the start (Shift+Enter) and collect every goal star without editing the track in between. That run is checked by the server, and your ghost and time are submitted with the track as the author time to beat.
Heads up: saving replaces this track for everyone and wipes all of its times and ghosts (the leaderboard reopens with your new run). The play count is kept. This can't be undone.
Like submitting, you must finish the edited track yourself first: restart from the start (Shift+Enter) and collect every goal star without editing in between.
Up to 50 riders race the same track with a synchronised start. Other riders appear as coloured ghosts; nobody can collide with anyone else. The host picks the track (your current Build track by default), vehicle and time limit.
