About This Test
A reaction time test measures how quickly you respond to a visual stimulus: watch the screen, and the instant the red square turns green, click anywhere. The time between the color change and your click — measured in milliseconds — is your reaction time.
This tool averages 5 rounds by default (10/15/20 optional) to filter out flukes and reflect your true speed. Timing uses the browser's high-precision timer, accurate to the millisecond. Gamers, athletes and casual users alike can use it to assess and train their reactions.
Clicking before the square turns green counts as a false start and restarts that round — this keeps results honest. Your final score can enter the global Top 100 leaderboard.

FAQ
What is a reaction time test?
It's a test that measures how fast you respond to a visual stimulus. When the red square on screen turns green, you click as fast as possible; the interval between the color change and your click is your reaction time in milliseconds. This test averages 5 rounds by default (10/15/20 optional) for a more stable result.
What's a normal reaction time?
The average visual reaction time for people aged 12–60 is about 250 ms. Elite athletes and esports pros reach 120–180 ms, while most adults fall between 180–350 ms. Anything under 120 ms is near the theoretical limit or a false start.
Why average 5 rounds?
A single round is easily distorted by momentary slips or jitters. Averaging multiple rounds filters out flukes. Five rounds balance accuracy and fatigue — steady but not tiring.
What if I click too early?
Clicking before the square turns green counts as a false start and the round restarts. This prevents jumping the gun and keeps results valid. Wait patiently for the color to change.
How can I improve my reaction time?
Train regularly with reaction tests, play fast-paced competitive games, keep a healthy sleep schedule, and do ball sports for hand-eye coordination. With weeks of practice, reaction times typically improve by 20–50 ms.
Does my score go on the leaderboard?
Your score is submitted automatically when you finish. If it makes the current Top 100, you'll be invited to leave a name — skip it and you'll be recorded as Anonymous. The leaderboard is right below the test area.
