4×4 Sudoku for Kids
The friendliest place to start. Fill every row, column and box with 1 to 4.
A 4×4 grid is the perfect first sudoku. There are only four numbers to place, so young players can spot patterns quickly and feel that 'aha!' moment fast. Tap a square, then tap a number — tap it again to clear it. When every row, column and little box has 1, 2, 3 and 4 exactly once, the puzzle is solved.
How to play 4×4 sudoku
The board is split into four little boxes, each two squares by two squares. You only need the numbers 1, 2, 3 and 4. The single rule: every row, every column and every little box must hold all four numbers, with no number repeated. Help your child read along a row first — if three numbers are already there, the empty square has to be the fourth. Tap a square, tap the number, and tap again to change your mind. Nothing breaks, so it's a safe place to guess and check.
What it teaches
A 4×4 grid is small enough to finish in a minute or two, but it's real logic the whole way through. To fill each square your child scans its row and column to see what's missing, then reasons 'if 2 is already here, it can't go there.' That's pattern-spotting, careful looking and step-by-step thinking — the same habits behind early maths and reading. Because there are no timers and no wrong-answer buzzers, children build focus and patience without any pressure.
When to move up
4×4 sudoku suits most children from around age 4 to 8 — younger ones can start with picture sudoku, where animals stand in for numbers. When your child solves a 4×4 grid without much help and starts asking for another, they're ready for more. The 6×6 grid is the natural next step: a bit bigger, a bit more to plan, still gentle. After that comes full-size 9×9 sudoku on the main play hub.
