6×6 Sudoku for Kids
Ready for a bigger board? Fill every row, column and box with 1 to 6.
Once 4×4 feels easy, the 6×6 grid is the natural next step. The boxes are two rows tall and three columns wide, and you place the numbers 1 to 6. It rewards a little more planning while staying friendly and fun — a great bridge toward full-size sudoku.
How to play 6×6 sudoku
A 6×6 board is divided into six rectangle boxes, each two squares tall and three squares wide. You place the numbers 1 to 6, and the rule stays the same as on a 4×4: every row, every column and every box needs all six numbers exactly once. With more numbers in play, the trick is to look in two directions at once — check what's already in a square's row and its column, and the answer is whatever neither one has yet. Tap to place a number, tap again to clear it.
What it teaches
The bigger grid stretches the same skills a little further. There's more to keep track of, so children practise holding a few clues in mind, working in a sensible order, and not giving up when the first square isn't obvious. That patience and methodical thinking is exactly what schoolwork asks for later. It still feels like a game — no clock, no score to beat — so the focus comes naturally, one square at a time.
When to move up
6×6 sudoku is a good fit once 4×4 feels easy, often around age 7 and up — but every child is different, so follow theirs. If the 6×6 grid still feels tricky, there's no rush: a few more 4×4 puzzles build confidence fast. When your child breezes through 6×6 and wants a real challenge, full-size 9×9 sudoku on the main play hub is the next big step.
