Only Green

Rules

1. A 3-second countdown, then the GO signal.
2. There are 8 rounds.
3. The light changes colour every 0.3 s to 0.65 s; 2 to 5 decoy colours show up before green.
4. Click as soon as it turns green.
5. The event lasts 45 s at most.

How scoring works

Each round scores more the sooner you click after green. Every click on another colour takes 300 away. Responding less than 100 ms after the signal counts as jumping the gun: that round scores 0.

Levels

Levels are earned by result; medals are only for the CCI Olympics.

Tips

• Do not trust similar shades: green means traffic-light green.
• A slightly slow green beats a click on yellow.
• Watch the centre of the screen, not the mouse.
