Reaction Time · ChrisSoft Games
Wait for the screen to turn green, then tap as fast as you can. Three rounds, measured in milliseconds. Free, no ads, plays in your browser.
How to play
- Tap to start, then wait — the screen is red.
- The instant it turns green, tap (or press Space) as fast as possible.
- Tapping too early (while red) restarts that round — no anticipating.
- Play 3 rounds; a faster average reaction time ranks higher.
