This free printable Sudoku puzzle for kids features a neat 6x6 grid, perfect for beginners. Each puzzle has 2x3 boxes outlined in bold, and about half the numbers from 1 to 6 are already filled in. Your child's job is to complete every row, column, and each of those six boxes using the numbers 1 through 6, ensuring no number repeats within any of them. It's incredibly satisfying to see the grid slowly fill up and click into place as you find each missing number.
To tackle this puzzle, encourage your child to start by scanning for a row, column, or 2x3 box that already has many numbers filled in. If a section is missing only one or two numbers, it’s often easier to figure out what those missing digits are. For example, if a row has 1, 3, 4, 5, and 6, the missing number must be 2. This strategy helps build confidence before moving to more complex areas.
For a practical tip, consider printing several copies and laminating one for repeated use with a dry-erase marker. This allows your child to try different approaches without wasting paper, or even to share the laminated puzzle with a sibling or friend as a collaborative problem-solving activity. This puzzle helps build logical thinking and number recognition in a fun, visual way.

Frequently asked questions
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.
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.
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.
