Guess Who — with times tables

The classic deduction game where every question is a maths question. Ask YES/NO questions about divisibility, multiples and times tables to find the secret number before your opponent finds yours.

How times tables are woven in

In Guess Who, the maths isn't a gate you have to get through — it IS the game. Every question your child asks is a maths question: "Is your number divisible by 3?" "Is it a multiple of 4?" They're thinking about multiplication, divisibility and number properties with every single turn.

1

Pick a secret number

Your child secretly picks a number from the board — this is the number their opponent has to guess.

2

Ask a YES/NO maths question

"Is your number divisible by 3?" "Is it greater than 15?" Champion answers yes or no — honestly.

3

Flip down & narrow in

Based on the answer, your child taps to flip down the numbers that can't be correct. The board shrinks with every question until they can guess.

Every question earns coins

3 coins per question asked, 15 coins per win. Coins are spent in the reward shop on avatars, themes and accessories — or redeemed for real-world rewards you set up as a parent.

"Show me how" — our most powerful feature

When your child isn't sure how to answer a question, they tap "Not sure? I can help" and Champion walks them through it step by step — explaining the maths trick (like the 3× table digit trick), checking it against their secret number, and helping them say YES or NO with confidence. Try it yourself below.

Two ways to play

Your child can play against Champion any time, or challenge a friend or sibling. Both are always available.

Champion

Play against Champion

Champion picks a secret number, answers your child's YES/NO questions honestly, and asks its own questions back. A real game of deduction — always ready, always beatable.

Play with friends

Challenge siblings, schoolmates and friends. Chat is locked during your turn so the focus stays on the deduction. Every chat message is visible to parents.

How we track progress

Every game is logged. We track which questions your child asked, how many turns it took to find the answer, and which number properties — divisibility, multiples, odd/even — they're getting confident with.

Adaptive engine

How adaptive learning works in Guess Who

The engine does not sit behind a separate dashboard. It runs inside Guess Who, shaping what happens next based on what your child needs.

Revision disguised as play

The questions children answer to narrow down their opponent are drawn from the facts the engine knows they need to practise. Playing a game is also doing targeted revision, without it feeling like it.

How it works: Every question in every game is an opportunity for the engine to reinforce a fact. Children never realise they are practising exactly what they need.

Not ready yet?

Guess Who asks children to think about divisibility, multiples and number properties — which is easier if they already know their times tables. If your child isn't there yet, our 12 learning levels build that understanding step by step.

Great for these learning types

Guess Who works particularly well for children with these learning needs.
