Reaction Timer

About Reaction Timer

Test your reflexes in a few seconds. It works with a mouse, a keyboard or a tap. Click to start, wait for the screen to turn green, then click as fast as you can. Click too early and the round resets. Most people land somewhere around 200 to 300 milliseconds; under 200 is quick. Your time depends on focus, sleep and even your mouse, so take a few tries and keep your best. The game remembers your best time on this device. Challenge a friend and see who's faster.
