How scoring works ＋
Round 1 is always 1.000 seconds. Then nine targets from 0.750–3.000 seconds arrive in a random order. Everyone gets the same mix, so longer targets don't make one run harder than another.
Your score is the mean absolute timing error: add up how many milliseconds early or late you were, ignoring the sign, and divide by ten. Lower is better. Zero is perfect. Early and late errors never cancel out. Results show rounded times; scoring uses microseconds. Ties go to the earlier saved best.
Ratings use average error (or a single round's error): perfect = 0; incredible ≤25ms; on point ≤75ms; nice touch ≤150ms; getting warm ≤300ms. A complete run saves your best on this browser. The shared board keeps one best per browser identity.
Tap the big pad, or use Space / Enter. There is no ticking, countdown or regular pulse. Switching apps or hiding the page during timing cancels the run. Timers left running for 30 seconds are canceled, not scored. Timing is measured on your device; this friendly leaderboard is not cheat-proof.
