This printable Sudoku puzzle features a 6x6 grid, perfect for introducing kids to the logic of number puzzles. About half the numbers are already filled in, giving a solid starting point within the six 2x3 boxes. The goal is to place the numbers 1 through 6 into every empty square, ensuring that each row, each column, and each of the six smaller boxes contains every number exactly once. There’s a quiet satisfaction in seeing all the numbers fall into place as you solve each section.
To tackle this Sudoku, encourage your child to look for rows, columns, or 2x3 boxes that already have many numbers filled in. If a row, for example, only has one empty square, they can easily figure out which number from 1 to 6 is missing and place it. This strategy of finding the 'easiest' spots first helps build confidence and provides quick wins, making the puzzle feel less daunting.
A practical tip for parents and teachers is to laminate this page after printing. Using a dry-erase marker allows your child to complete the puzzle multiple times, erase mistakes easily, and practice without wasting paper. This also makes it a great resource for small group work, where children can take turns solving sections or collaborate on finding the missing numbers, boosting both their problem-solving and communication skills.

Frequently asked questions
What does sudoku teach besides numbers?
Logic, mostly — sudoku needs no arithmetic at all. Kids practice deduction ("this is the only place a 3 can go"), process of elimination, and the patience to check their own work. It's one of the best focus-builders that still feels like a game.
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.
Is this too babyish for my 8-year-old?
Try it before assuming — kids this age still love a good puzzle or coloring session, especially with "grown-up" tools like gel pens or fine-tip markers. Adding a self-set challenge (a timer, a color pattern, beating a sibling's time) refreshes any page.
