This free printable Sudoku puzzle features a 6x6 grid, perfect for kids ready to step up from smaller puzzles. You’ll find about half the numbers (1-6) already filled into the squares. Your goal is to complete each row, each column, and each of the six 2x3 boxes so that every number from 1 to 6 appears exactly once, with no repeats. There’s a quiet satisfaction in placing each number correctly and seeing the grid fill up perfectly.
To tackle this puzzle, try focusing on a single 2x3 box first. Look for a box that has only one or two numbers missing. For example, if a box has 1, 2, 3, and 5 already in it, you know the missing numbers must be 4 and 6. Then, check the rows and columns that intersect that box to figure out where the 4 and 6 should go. This strategy helps break down the larger puzzle into smaller, more manageable steps.
A great 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 again and again. It’s perfect for car trips, quiet time in the classroom, or as a quick mental warm-up, and helps build logical reasoning and number sense in an engaging way.

Frequently asked questions
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.
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.
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.
Why does the page look cut off when I print?
That's almost always a scaling setting. In the print dialog choose "Fit to page" (or 100% if your printer handles margins well) and make sure the paper size is set to US Letter. Printing from the downloaded PDF, rather than the browser preview, also gives the cleanest result.
