This free printable features a 6x6 Sudoku grid, specifically designed for kids. You'll find a sturdy outline that prints clearly, enclosing six rows, six columns, and six larger 2x3 boxes. About half the numbers, from 1 to 6, are already filled in for you. The satisfying challenge is to complete the rest, ensuring that each row, each column, and each of the six 2x3 boxes contains every number from 1 to 6 exactly once, with no repeats.
To solve this particular Sudoku, we recommend starting with the 2x3 boxes that have the most numbers already filled in. Scan these boxes first to see which numbers are missing. Then, look at the rows and columns that intersect those boxes. By checking what numbers are already present in the intersecting rows and columns, you can often deduce the correct missing number for an empty cell within that box.
A great tip for this page is to laminate it after printing. This allows your child to use a dry-erase marker to complete the puzzle again and again, saving paper and offering repeated practice. This Sudoku puzzle helps build critical thinking and logical reasoning skills, perfect for quiet individual work or a fun challenge during a car ride.

Frequently asked questions
Is this sudoku size right for a beginner?
Smaller grids are the on-ramp: 4×4 boards suit first-timers, 6×6 suits kids who've solved a few and want more of a challenge. This 6×6 is a good step up once the 4×4s feel easy.
How long should a kids' sudoku take?
Anywhere from five minutes to half an hour is normal, and speed doesn't matter. If it's over in two minutes, move up a grid size; if it stalls completely, solve the next number together and hand the pencil back.
Can my child do this one alone?
That's the sweet spot of this age — hand it over and let them own it. Resist hovering: figuring out a sticking point solo (or choosing to ask for help) is a bigger win than a perfectly completed page.
