Wait for the screen to light up, then tap it as fast as you can. Too early and you lose a life. Too slow and you lose a life too — the target time shrinks with each successful round. Three misses and the session ends.
What it trains
Reaction trains reaction speed — the time between a signal and your response. Average human visual reaction time is 200–250 ms. With practice, most people get down to 180–200 ms. Faster reaction helps in sports, driving, gaming, and many everyday situations.
Tips to improve your score
Use a keyboard: press Space instead of tapping — often 10–20 ms faster.
Sit still. Movement of the head adds latency.
Look slightly above the screen center — peripheral vision reacts faster than central.
Don't anticipate. If you try to guess the moment, you'll tap too early and lose a life.
Frequently asked questions
What's a good reaction time?
Under 250 ms is average, under 200 ms is fast, under 180 ms is excellent.
