How to play

Work it out. Each question is an everyday sum: a discount, a tip, a split bill, a unit price or the change from a note.
Answer. Tap one of the four amounts, or press 1 to 4.
Level up. Every 3 right answers in a row, the sums get harder. A wrong answer costs 2 seconds, sends you back to level 1 and shows how to work it out.
Score. 10 points a right answer at level 1, then 15, 20 and 25 at levels 2, 3 and 4.

Quick tips

Find 10% first. Move the decimal point one place: 10% of £45 is £4.50. Double it for 20%, halve it for 5%.
Use quarters and halves. 25% off is a quarter off; 50% off is half price. Easy fractions beat long multiplication.
