The ball never stops rolling. Tap to jump to the next
platform — but only once it has swung under you.

How hard
The track is built from five shapes. Turn each one up
or down to get more or less of it.

👆 One tap
Tap anywhere to jump to the next platform. That is the only control.
⏱️ Two ways to fall
Too late — the ball is always rolling forward. Wait, and you run
off the end of your platform. Too soon — the next platform has to swing under you first. Jump
before it arrives and the world turns anyway, so you land on nothing.
🛤️ The track changes shape
Every so often the world rearranges itself: a tube you spiral down, an
unrolled ribbon, a half-pipe you rock across, a long rolling road, a
spiral staircase you climb. The jump is timed exactly the same in all
of them — only the view changes.
🔎 What you are looking at
💚 Green platforms
Every tenth one is green. They are landmarks, not checkpoints — nothing
about them is safer. They are there so you can see how far you have come.
🏃 It gets faster
The longer you last the quicker the ball rolls, so each platform gives you
less time to tap: 279 ms at the start, down to
161 ms once it is up to speed. It never becomes
impossible — the window never closes below
140 ms.
If that is still too quick, Settings · How hard has two
easier settings. They stop the ball speeding up as much, which leaves
you more time on every platform.
