How fast are your reflexes? This reaction time test measures exactly how many milliseconds it takes for your brain to process a visual signal and send a command to your hand. The average human reaction time is about 250ms. Professional gamers often score below 180ms. Athletes in sports like sprinting and Formula 1 can react in under 150ms. Track your progress over multiple attempts and see how you compare! This game is scientifically designed to give accurate readings by using random wait times to prevent anticipation.
Wait for the red box to turn GREEN, then click/tap as fast as you can! Do NOT click during red or the test resets. Your time is measured in milliseconds. Take 5 attempts and your average is calculated.
Stay focused but relaxed - tension actually slows reaction time. Position your finger or cursor directly over the box before the test begins. Try to react to the color change itself rather than anticipating it. Morning tests tend to be slower than afternoon ones due to circadian rhythms.
