🎮 How to play
Tap the instant the screen changes — five rounds, measuring your reaction time.
- Tap when the colour flips (Space): Stop the clock
🏆 Scoring & strategy
- Rated on your average reaction time across the five rounds.
Quick tip: Tapping before the change is a foul, so resist the urge to guess the timing. Around 200–250ms is a genuinely good human average.

Try the reaction time test online
Reaction Test measures how quickly you respond to a visual signal. Wait while the screen stays in the ready state, then tap or click the instant it turns green. Your reaction time is recorded in milliseconds, and five attempts give you a more useful average than a single lucky run.
The timer starts only after the green state has actually been rendered, which avoids measuring time before the player can see the signal. That makes this online reflex test better suited for comparing your own attempts across phone and desktop sessions.
