What is a good reaction time?

Average human reaction time to a visual cue is about 200–250 ms. Competitive gamers often land around 140–160 ms, and the practical human limit is near 100 ms.

How is reaction time measured here?

You click the moment the screen flips from red to green. We measure that gap in milliseconds across 5 rounds and average them.

How can I improve my reaction time?

Stay focused and relaxed, get enough sleep, warm up, and reduce distractions. Consistent practice and good ergonomics help shave off milliseconds.
