About F1 Reaction Test

The F1 Reaction Test simulates the start of a Formula 1 race. Five red lights turn on one by one, and then extinguish after a random delay. Your goal is to click (or tap) as fast as possible the moment the lights go out. This tests your visual reaction time and anticipation skills.
