How to Play Reaction Time Test
- Click to start, then wait for the red screen to turn green.
- Click as fast as you can the instant it goes green.
- Click too early and the round restarts — no jumping the gun.
- Play five rounds to get your average reaction time in milliseconds.
Tips & Strategy
- Keep your finger resting on the mouse button or screen — travel time is pure loss.
- Don't try to predict the timing; reacting to the colour beats guessing.
- Test when alert: sleep, caffeine and time of day visibly move your numbers.
Reaction Time Test — Frequently Asked Questions
What is a good reaction time?
The median human visual reaction time is around 250 ms. Under 220 ms is quick, and under 180 ms is exceptional for a click test.
Why is my phone score different from my computer?
Touchscreens and displays add different input and refresh latency, so compare scores only on the same device.
Can I improve my reaction time?
You can shave off tens of milliseconds with alertness and practice, but most of your baseline is physiology — consistency matters more than one lucky fast click.
