Reaction Time Test

This simple reaction time test measures how quickly you respond to a visual signal.

Your reaction time can vary depending on your device, screen, focus, and even the time of day. This game is designed for fun and self-challenge, not as a professional cognitive assessment.

Try a few rounds to get your average score. Can you beat your personal best?

How to Play

  1. Tap or click the Start button to begin each round.
  2. Wait patiently for the screen to turn green.
  3. Click as quickly as you can when you see green.
  4. If you click too early (before green), that round is cancelled.
  5. Try several rounds to see your average reaction time.

This game is for entertainment purposes only and does not measure professional cognitive performance. Results may vary by device and screen.
