Pick an age and click Generate new for a kid-sized sudoku with a fresh arrangement every time. Ages 6–9 get a 4×4 grid with 8 empty cells — small enough to teach the core rule (every row, column and box uses each number exactly once) without tears. From age 10 the puzzle grows to a 6×6 grid with 16 blanks: a genuine challenge that still fits comfortably on one page.
Every puzzle prints with its completed solution grid, so you can check answers or hand a stuck solver one honest hint. Click Print and choose A4 or US Letter — the bold box borders stay clear in black and white. Sudoku is a brilliant quiet-time logic workout: no reading required, just careful elimination, and because every grid is freshly generated there is always another puzzle waiting.
