In short: This reaction time test measures how many milliseconds it takes you to click after the screen turns green, averaged over five rounds. The average human reaction time is around 250 ms; gamers often score 180–220 ms.

How to use

Click to start. The box turns red. Keep your finger ready but don't click yet.
Click on green. After a random delay the box turns green — click immediately. Clicking early means you redo that round.
See your average. After five rounds you get your average in milliseconds and a ranking. Share it as a challenge link or a score card.

FAQ

What is the average human reaction time?

For a simple visual stimulus like this one, most people average 200–300 ms, with about 250 ms being typical.

What is a good reaction time for gaming?

Under 200 ms is excellent and common among competitive gamers. 200–250 ms is good and above average.

Why is my score different on another device?

Screens and mice add their own delay. A 60 Hz monitor alone can add up to 16 ms, and wireless or Bluetooth mice add a little more. High-refresh monitors give lower times.

Can I improve my reaction time?

Yes — sleep, caffeine timing, warm-ups and practice all help a little. Most improvement comes from consistency: fewer slow outliers.

Why five rounds?

A single click is noisy. Averaging five rounds gives a much more reliable number.
