This free printable offers a 6x6 Sudoku grid, divided into six smaller 2x3 boxes. About half the numbers, from 1 to 6, are already filled in, giving your child a satisfying head start. The goal is to complete each row, column, and 2x3 box so that every number from 1 to 6 appears exactly once, with no repeats. There’s a quiet satisfaction in scanning the grid and slotting in that final correct number.
To tackle this puzzle, encourage your child to start with a row, column, or 2x3 box that has the most numbers already filled in. For instance, if a row already has five numbers (like 1, 2, 3, 4, 5), it’s easy to see that the missing number must be 6. This strategy helps build confidence and provides quick wins before moving on to trickier sections of the grid.
A practical tip for this page is to print a few copies and laminate one for reusability. Your child can then use a dry-erase marker to solve the puzzle, wipe it clean, and try again later, or even pass it to a sibling. This not only saves paper but also reinforces the logic as they practice, strengthening their number sense and problem-solving skills.

Frequently asked questions
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.
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.
