Wait for green and test your reaction speed
How to play
Wait for green, then press. Complete 5 attempts: the leaderboard uses the median (the middle result), not the fastest attempt. A false start or switching tabs resets the series. You have 2 minutes. Old single-attempt records are excluded. This is an entertainment test: device latency affects results; checks discourage cheating but cannot eliminate automation.
No sign-up needed: records stay in this browser and you appear on the shared board as Guest. Sign in with ELMIX ID to show your name there.
