How to play — Reaction Tap
- Tap Start, then wait. The box will turn green after a short delay.
- Tap as soon as it turns green — your reaction time is measured in ms.
- If you tap too early (while waiting), that round is a false start.
- Play 5 rounds. Your average time is the final score (lower is better).
- Best average is saved on this device. Use New game to retry.
