On this page, you’ll find a 6x6 Sudoku grid, specially designed for kids. Half the numbers, from 1 to 6, are already filled into the grid. Your child’s task is to complete each row, column, and the six 2x3 boxes by placing the remaining numbers 1 through 6, ensuring no number repeats within any of these sections. There’s a quiet satisfaction in seeing the grid gradually fill up, with each correct placement bringing them closer to the completed puzzle.
To tackle this Sudoku, encourage your child to start by looking for a row, column, or 2x3 box that has the most numbers already filled in. For example, if a 2x3 box only has one empty square, they can easily figure out the missing number by seeing which number from 1-6 is not yet present in that box. This simple elimination strategy helps build confidence and provides quick wins.
A practical tip for parents and teachers is to laminate this page after printing. This allows children to use a dry-erase marker, making the puzzle reusable for multiple attempts or for different children. It’s also a great way to introduce the concept of logical reasoning and spatial awareness in a fun, low-pressure format.

Frequently asked questions
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.
Should kids solve sudoku in pencil?
Definitely pencil, with an eraser nearby. Guessing and backtracking are part of learning the game, and being able to erase keeps it playful. Writing tiny "candidate" numbers in a corner of a square is a real solver technique kids enjoy discovering.
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.
