Round 1 of 5

Test how fast you can react. Five rounds, lower is better.

How to play
  • Click the big area to start a round, then wait.
  • The panel turns red — do not click yet.
  • The instant it turns green, click (or tap, or press Space) as fast as you can.
  • Click too early and the round resets — patience pays off.
  • After five rounds you get your average and a rating.
