Test de réflexes en ligne

This test measures the time between the visual signal and your response. Start the test, wait for the signal and react as quickly as possible.

Your best time is saved locally so you can try to improve it. Clicking too early counts as a false start rather than a valid reaction.

How to get a consistent result

Use the same device and keep your finger still until the signal appears. Try several rounds if you want to compare results because individual reactions can vary.

Then try Odd One Out to combine speed with visual attention.

Un autre défi vous attend. Try memory, sequences, or the daily challenge.

GUIDE PRATIQUE

How to interpret your reaction time

The result measures the interval between the game’s visual signal and your tap. This is a recreational test, not a medical assessment or laboratory measurement.

Make your test more consistent

Place the device on a stable surface, keep your finger ready without touching the screen, and wait for the green signal. Do not click early: an early start is not a valid reaction. Try several rounds and compare the overall pattern, not only your best result.

What can affect the result?

Display latency, mouse or touchscreen response, browser, attention and tiredness can all affect the measured time. For comparisons, use the same device under similar conditions.
