About F1 Start Reaction Test

GGReflex F1 Start recreates the Formula 1 start sequence. Five red lights go on one by one — the moment they all go out, click as fast as you can. Jump the start and you fail.

How it works

  • Wait for all five lights to go out, then click.
  • Clicking before lights-out is a jump start.

Result: reaction time (ms). Free to play, no signup.
