How the Reaction Time Test works
Click the box to start. It waits a random amount of time before turning green — click the instant it does, and we measure the exact time between the color change and your click, down to the millisecond.
Click too early, while it's still red, and it counts as a false start rather than a real reaction. You'll get 5 rounds per session, with your average and fastest reaction shown at the end.
