How to play
Pick a game and a level, then answer as many questions as you can in 60 seconds. Every right answer scores points, and answer streaks earn bonus points. A wrong answer in Quick Sums or True or False costs 3 seconds, so speed only helps if you stay accurate.
Quick Sums
A sum appears on the board with four possible answers. Tap the right one, or press 1 to 4 on a keyboard. If you pick wrong, the correct answer is circled in green.
True or False
The board shows a finished sum, like 8 × 7 = 54. Is it right? Tap True or False, or press T or F. It is the fastest of the three games, and a good way to drill times tables.
Add It Up
The board shows a target number and a grid of 16 numbers. Tap numbers that add up to exactly the target. Hit it and those numbers are wiped and replaced, and you gain a second on the clock. Go over and your selection is cleared. Using more numbers scores more points, so do not always reach for the biggest ones.
Levels
| Level | Quick Sums and True or False | Add It Up |
|---|---|---|
| Easy | Adding and taking away with small numbers | Targets 8 to 15, numbers 1 to 6 |
| Medium | Adding and taking away up to 120, times tables to 10 × 10 | Targets 14 to 25, numbers 1 to 9 |
| Hard | Bigger numbers, times tables to 12 × 12 and division | Targets 20 to 36, numbers 1 to 12 |
Tips
- Estimate first. In Quick Sums, rule out answers that are clearly too big or too small, then check the last digit.
- Check the last digit. In True or False, 7 × 8 must end in 6, so 54 is false straight away.
- Build from big to small. In Add It Up, take the biggest number that fits, then fill the gap.
- Keep the streak alive. A long streak is worth more than a few quick guesses.
