Editorial team · Published July 23, 2026
Here’s a 6x6 Sudoku grid, specially designed for kids, where you'll complete each row, column, and 2x3 box using the numbers 1 through 6, ensuring no number repeats in any line or section. Roughly half the numbers are already filled in, giving you a great head start on solving the puzzle. There’s a satisfying click when you place that last number and see a perfectly completed grid, all by your own clever thinking. This particular layout provides a great balance of challenge and achievement for young minds.
To begin, look for a row, column, or 2x3 box that already has most of its numbers filled in. If a section only needs one or two more numbers, it's often easiest to figure out which ones are missing there first. For example, if a row has 1, 2, 4, 5, and 6, you know the missing number must be 3. Filling in these simpler sections can then reveal clues for the more complex parts of the puzzle, helping you progress step by step.
A great way to reuse this puzzle is to print it once and then slip it into a clear plastic sleeve. Your child can then use a dry-erase marker to fill in the numbers. When they're done, simply wipe it clean, and it's ready for another attempt or for a sibling to try. This method saves paper and offers repeated practice in logical thinking and number recognition, building valuable problem-solving skills in an eco-friendly 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.
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 #28 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.
Will it print okay in black and white?
Yes — the printable itself is black line art on a white background, so any printer handles it, including basic laser printers. Set your printer to grayscale or "black ink only" to save color ink; the page will look exactly the same.
