One or Two

Rules

1. A 3-second countdown, then the GO signal.
2. There are 8 rounds.
3. After a wait of 0.8 s to 2.2 s, a 1 or a 2 appears.
4. On a 1, one click; on a 2, a double click (the second click within 0.4 s).
5. The event lasts 40 s at most.

How scoring works

Each round scores more the faster you answer. Getting the number wrong makes the round score 0. All 8 add up. Responding less than 100 ms after the signal counts as jumping the gun: that round scores 0.

Levels

• Gold level5,600 points
• Silver level5,000 points
• Bronze level4,200 points

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

Tips

• Read the number before you move your finger: haste costs you here.
• Have the double click ready: it is the one that eats the most time.
• Watch the centre of the screen, not the mouse.
