Sudoku for Kids
A tiny 4×4 grid with just four numbers to place makes the friendliest introduction to Sudoku for children and first-time players. There's no maths and barely any reading involved.

A 4×4 Sudoku uses only the numbers 1 to 4 in a grid of four 2×2 boxes. The rule is the same as the big version (each row, column and box holds every number once), but with far fewer cells a child can finish a whole puzzle and get that "aha!" moment quickly.
- Small, quick puzzles that build confidence.
- Tap a square, tap a number — that's the whole control scheme.
- Gentle on-screen highlights show where numbers can go.
- Free, browser-based, with nothing to install.
Growing into bigger grids
Once 4×4 feels easy, try a 6×6 grid, then move up to the classic 9×9 Sudoku on Easy. Parents and new players can read the quick how to play Sudoku guide to help explain the rules.
Frequently asked questions
What age is Sudoku for kids suitable for?
The 4×4 grid works well for children from about age 4 or 5 who can recognise the numbers 1 to 4. It builds focus and pattern-spotting in short, winnable puzzles.
Do kids need to be good at maths to play Sudoku?
No. Sudoku involves no arithmetic at all — the numbers are just four different symbols. A child only needs to notice which symbol is missing from a row, column or box.
What size Sudoku is best for children?
Start with 4×4, which most kids can finish in a minute or two. When that feels easy, a 6×6 grid is the natural next step before the full 9×9.
