About this tool
Click the box to start. Wait until it turns from red to green, then click as fast as you can. Clicking too early starts the round again. Try several times to get your average and best time. Most people react in 200 to 300 milliseconds.
Frequently asked questions
What is a good reaction time?

Why does the wait time change?
The random wait stops you from guessing the moment.
