About Reaction Speed
Reaction Speed measures pure reflex time in milliseconds. Wait for the red panel to turn green, then tap instantly — tap too early and you'll have to start over. It's simple, brutally honest, and endlessly replayable.
How to play
- Tap Start and wait for the panel to turn green
- Don't tap while it's still red — that resets the round
- The instant it turns green, tap as fast as you can
- Your reaction time in milliseconds is your score — lower is better
