Tip: rest your finger on the mouse and watch the box, not the timer.

How to use

Press Start, wait for green, then click as fast as you can. Everything runs in your browser.

How does it work?

Click when the box turns green — 5 rounds, then your average. Clicking too early voids the round.

What is a good score?

Under 250ms is solid; under 200ms is excellent.
