How to play Pixel Reaction Time
Click or tap to begin, wait for the screen to turn green, then click as soon as you see the change. The result is shown in milliseconds and the best result is saved locally in this browser. Restart when you want another attempt.

Browse quick games, or try Whack-a-Mole for a longer reflex round.
