Verify a run

Paste a proof code. The game replays every input and checks that it lands on the same distance.

How proof works

A proof code is the course seed plus the exact frame of every press and release. The physics is deterministic, so replaying those inputs has to land on the same distance, to the metre.

Timing tells people from scripts: fingers scatter their release angle and can't re-press in under 60 ms.
