Guess the hidden sum in six tries. One puzzle a day for everyone, at three levels.
12+3=15
Numbers cannot start with 0, division must work out exactly, and × and ÷ are done before + and −.
Swaps teal and gold for blue and orange.
Each day there is one hidden sum at each level. Your guesses must be true sums, so every guess is real arithmetic practice: you check number facts, think about the order of operations and reason about which numbers could fit. After each guess the colours narrow down the answer, like Wordle but with numbers and signs.
| Level | Boxes | Uses | Example | Good for |
|---|---|---|---|---|
| Easy | 7 | + and − | 12+3=15 | Ages 7 and up (KS2), and families playing together |
| Classic | 8 | + − × ÷ | 4×7−8=20 | Ages 11 and up (KS3 and GCSE), adults and teachers |
| Hard | 10 | + − × ÷ and brackets | (3+5)×4=32 | Confident solvers who like a challenge |
