Time Guess

How long does a moment feel?

Small rules. Big focus.

1. Six targets each ask for a random 1–5 seconds. Press a target to start it, then press the same target again when you think its time is up. Multiple targets can run together; no live clock is shown.
2. Your score is the sum of your absolute timing errors in milliseconds.
3. Complete all six targets to get a result. Early and late errors never cancel each other. A smaller total error is better; it is not an average.
4. Tap, click or focus a target and use Space or Enter. Completed targets and held-key repeats do not count again. Leaving for the background interrupts the whole game.

No sign-up. Just a little play.
