How your score is calculated

Since a single attempt can be a fluke, this test averages five trials to give you a score you can actually trust. Create an account and log in to compete on the leaderboard.

Results of a few hundred milliseconds are common on simple reaction tests like this, but averaging several tests will give a more accurate score. Your result may change based on device, mouse, screen refresh rate, and browser lag, so always test on the same device for consistent tracking.

Tips to react faster

• Watch the box, not your cursor. Your eyes catch the color change before your hand needs to move.
• Don't anticipate. Guessing when green is coming leads to false starts that restart the round.
• Stay relaxed. A loose wrist and steady focus will perform better than a tense, jumpy hand.

Can you improve your reaction time?

Yes. Practicing regularly can improve your times as your brain gets familiar with the task, although training alone will only get you part way. Try checking your reaction time at different times of the day and with and without caffeine to see when you perform best.
