Here's a 6x6 Sudoku grid designed especially for younger puzzlers. About half the numbers, from 1 to 6, are already filled in, leaving plenty of blank spaces for your child to complete. The goal is simple: fill in every empty square so that each row, each column, and each of the six 2x3 shaded boxes contains all the numbers from 1 to 6, with no repeats. There’s a quiet satisfaction in seeing all the numbers slot perfectly into place and completing the entire grid.
To help your child start, suggest they look for a row, column, or 2x3 box that has the most numbers already filled in. For example, if a row is only missing one number, they can quickly figure out which number from 1 to 6 is needed to complete it. This strategy of finding the "easiest" nearly complete sections first can build confidence and provide a solid starting point for tackling the rest of the puzzle.
To get more use from this Sudoku, print a few copies and have siblings or classmates race to see who can finish their grid first. This adds a fun, competitive element and encourages quick thinking. Alternatively, laminate a single copy and provide a dry-erase marker; this allows for repeated attempts, error correction without needing new prints, and lets your child practice until they've mastered the logic and number placement.

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.
My child says the puzzle is impossible. Now what?
It isn't — every grid starts from a fully valid solution, so a way through always exists. The trick is to hunt for the most-filled row, column or box and ask what's missing there. If a wrong number went in early, a fresh printed copy is often kinder than untangling the error.
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.
