Reaction Time Test
Test your reflexes — wait for green, then click as fast as you can. Measures your reaction time in milliseconds with best and average stats.
Press the button, then wait for green
Hit the button, wait for it to turn green, then slam it as fast as you can. Average human reaction is around 250 ms.
Reaction Time Test measures how quickly you respond to a visual signal, reported in milliseconds. Press the launch button to arm a round, wait through a random delay, and slam it the instant the button turns green. It tracks your best and average times so you can see your reflexes sharpen over repeated attempts.
How to use the Reaction Time Test
- Press the red button to start a round and arm the timer.
- Keep watching and wait while the button stays red — do not press early.
- The moment it turns green, hit the button as fast as you can.
- Read your reaction time in milliseconds, then go again to beat your best.
Frequently asked questions
- What is a good reaction time?
- The average person clicks in roughly 250 milliseconds. Anything under 250 ms is quick, and times below 200 ms are excellent and typical of practiced players.
- Why did it say I clicked too soon?
- If you press while the button is still red, the round counts as a false start. Wait for the green signal before pressing — the delay before green is randomized so you cannot predict it.
- What affects my reaction time?
- Sleep, caffeine, focus, screen refresh rate, and input lag from your mouse or touchpad all play a part. Testing several times and reading your average gives a more reliable picture than a single attempt.
- Does it save my best score?
- Your best and average times are tracked for the current session in the browser. Refreshing or closing the page clears them, so the test always starts fresh.
