How to Play
- Click, tap or press Space on the pad to start.
- Wait while the pad is red. After a random delay it turns green.
- Click (or press Space) the moment it turns green.
- Clicking too early does not count — just retry the round. After five rounds you get your average.
Tips & Strategy
- Rest your finger on the button or Space bar so you only need to press.
- Focus on the pad, not on the timer.
- Results vary with your device and screen; compare against your own best on the same device.
