Click the panel to begin an attempt — it will turn red
Wait patiently. After a random delay (1–3 seconds) the panel turns green
Click as fast as you can once it turns green — your reaction time is shown in milliseconds
If you click while it's still red, the attempt is marked too early — stay patient
Play 5 attempts in a row; your best and average are calculated
Average human reaction time is around 250 ms — under 200 ms is excellent
Your best time is submitted to the leaderboard (lower is better)
