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 feel the "aha!" 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.
