Reaction Time Test
The Reaction Time Test measures how fast you respond to a visual cue, in milliseconds, and tracks your best score so you can try to beat it.
How fast are your reflexes?
Wait for the screen to change, then click as quickly as you can. The test records the milliseconds between the cue and your click. It is a simple, addictive measure of reaction time - and clicking too early counts as a false start, so you have to genuinely react, not guess.
What the numbers mean
Average human visual reaction time is around 200–250 milliseconds; gamers and athletes often score lower. Your result varies with focus, tiredness, and screen and mouse lag, so try several rounds and take your best. It is a fun way to compare reflexes with friends.
Frequently Asked Questions
What is a good reaction time?
Average visual reaction time is about 200-250 milliseconds. Faster than 200 ms is quick; well-trained gamers can go lower.
What happens if I click too early?
Clicking before the cue counts as a false start, so you have to genuinely react rather than anticipate.
Why do my results vary?
Focus, tiredness, and screen or mouse lag all affect the reading, so take several attempts and use your best.
Does it save my best score?
