Editorial team · Published July 13, 2026
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 spaces for your child to complete. The larger 2x3 boxes help them visually break down the puzzle. It's incredibly satisfying to fill in the last missing number, knowing every row, column, and box now holds each digit from 1 to 6 exactly once.
A good way to start this puzzle is to look for rows, columns, or 2x3 boxes that already have many numbers filled in. For example, if a row is missing only one number, your child can quickly figure out what it must be by seeing which number from 1 to 6 is absent. This strategy makes the puzzle feel less overwhelming and builds confidence early on.
Parents and teachers can extend the fun by laminating this page after it's printed. Then, children can use a dry-erase marker to complete the puzzle again and again. This offers endless opportunities for practice without needing to print multiple copies and helps reinforce logical thinking and number recognition skills.

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.
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.
What age is the Sudoku for Kids #25 for?
It's aimed at kids ages 5–8 — enough detail to be interesting without being fiddly. Younger siblings can join in with help, and the range is a guide, not a gate: match the child, not the label.
