Reaction Time Test

How it works

Start the test, wait for green and click or press Enter or Space as quickly as possible. Complete five rounds to add a run to your session history. A false start repeats the current round; restarting discards the unfinished run. Nothing is uploaded and no account is required.

A quick reflex game for gamers and everyday breaks

Try a five-round run before your next gaming session, during a study break or whenever you have a moment to spare. Play again to challenge your own average. Your runs stay in order on this page, with a percentage comparison after each completed run. This is a personal reflex challenge, not a prediction of your performance in any game.

Useful to know

Lower averages are faster. Runs stay in completion order, with new runs added at the bottom and the best average marked. Each percentage compares with the immediately preceding completed run. Improvement = (previous average − current average) ÷ previous average × 100. Up to 50 runs stay only in page memory and are cleared on reload, navigation or closing the page. No reaction times are uploaded. Results vary with your display, browser, input device and attention. Use the same setup when comparing runs.
