Sale Season

Rules

1. A 3-second countdown, then the GO signal.
2. Shop percentages and fractions: «25% of 80», «half of 46», «price with 20% off».
3. Each question comes with three answers.
4. You answer with the 1, 2 and 3 keys or by clicking the answer.
5. You get 1 min from the signal.

How scoring works

Every right answer scores, more the faster you answer, and every wrong one costs you.

Levels

• Gold level1,900 points
• Silver level1,300 points
• Bronze level700 points

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

Tips

• 10% is just moving the decimal point: from there, 20% is double and 5% is half.
• When in doubt, rule out: the last digit is often enough to tell which one it is not.
