Reaction Time Test

Wait for green, then click as fast as you possibly can. Wait for green, then click as fast as you possibly can. Five goes, and the median is your score — because one slow blink should not define your reflexes.

Reaction time test — how fast are your reflexes?

This free reaction time test measures how quickly you respond, in milliseconds. Wait for the panel to turn green, then click when green as fast as you can. You get five goes, and your score is the median — so one slow blink doesn’t define your reflexes.

Two more tests measure different skills. The Go / No-Go test shows green or red: click on green and keep still on red, which tests how well you can stop as well as start. The aim trainer puts up thirty targets one at a time and measures how fast you can move and react. All free, in your browser.

Why players love it

Why players love Reaction Time Test

Simple to pick up, easy to love.

Classic reaction test

Green means click. The one everybody means by "reaction time".

Go / No-Go

Red means keep still — it tests your brakes as well as your speed.

Aim trainer

Thirty targets, one after another, timed to the millisecond.

A fair score

The median, not the average, so one slow go cannot define the run.

No cheating it

A click faster than human nerves is logged as a false start.

Mouse, key or thumb

Click, tap or press Space — whatever is fastest for you.

What is an average reaction time?

Most people score between 200 and 300 ms on a visual reaction speed test like this one; under 200 ms is excellent. Anything under 100 ms is faster than a nerve signal can travel from eye to hand, which is why it counts as a false start. Your screen and mouse add a little delay too, so your true reflexes are probably a shade quicker than any web test can show. Try it a few times a day and see how consistent you can be.

How to play

How the reaction test works

Click to start, then wait while the panel is blue.
After a random delay of one to four and a half seconds, it turns green — click immediately.
Clicking early, or faster than 100 ms, is a false start.
After five goes, your median time is your score.

Tips & tricks

How to improve your reaction time

Watch, don’t guess. The delay is random. Anticipating only gives you false starts.
Relax your hand. Keep a finger resting lightly on the mouse button or Space bar.
Use a wired mouse and a fast screen. Your devices add a few milliseconds of their own.
Rest and warm up. Reflexes are sharper when you’re awake and have had a few practice goes.
Train with Go / No-Go. Learning to hold back on red sharpens focus for every test.
