This free printable sudoku offers a fun 6x6 grid, perfect for introducing kids to logic puzzles. About half the numbers, from 1 to 6, are already filled into the squares. Your child’s task is to complete each row, column, and the distinct 2x3 boxes so that every number from 1 to 6 appears exactly once in each section. There's a real satisfaction in placing that last correct number and seeing the completed puzzle.
A good way for a child to start this specific puzzle is to look for rows, columns, or 2x3 boxes that have only one or two missing numbers. For example, if a row has five numbers already filled in, it's easy to deduce the single missing number needed to complete that row. This strategy helps build confidence and provides quick wins as they progress through the grid.
To get more use out of this page, print several copies and laminate one. Your child can then use a dry-erase marker to solve it repeatedly, allowing them to try different strategies or even race against themselves. This reinforces number recognition and critical thinking skills in an engaging, reusable 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.
How do I explain sudoku rules to a child?
One sentence: every row, every column and every box must have each number exactly once. Start by pointing at a nearly-full row and asking "what's missing here?" — kids grasp the rule fastest by finding one forced number, not by hearing the theory.
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.
