Free Online Reaction Time Test Game

Test your reaction with this online reaction time tester and try to set a high score. In this game you test your reaction time to a visual color change by clicking or tapping the screen once you see the change. The average human reaction time to visual stimuli is about 0.26 seconds, so if you can get under than, you are doing well. On the other side, the lowest possible human reaction time (without cheating and trying to anticipate the change) is about 0.11 seconds. So if your time is below that your results are disqualified. Practicing your reaction time with a game like this can be useful for training your brain and improving your overall health and well-being.
