How challenges work

5 rounds · A false start or a missed green ends the whole run. Lower average wins.

20 rounds · 12 green, 8 orange · 1 second to respond. More correct rounds wins; speed breaks ties. Each run has a new random order.

Results include device and browser latency. Compare sessions on the same setup. For fun, not a clinical assessment.

Links contain unverified scores and a nickname, readable by anyone with the link. No login, live syncing, or automatic notifications.
