How to teach Sudoku to kids
Sudoku is a logic puzzle, so children do not need to add or subtract. Start with a grid they can comfortably read and solve the first puzzle together. If rows and columns are new to them, the optional number activities above can help you introduce those terms.
Find the missing number
Start with a very easy 4×4 worksheet. Explain: “Each row needs 1, 2, 3, and 4.” Point across a row with one empty square and ask which number is missing.
Check the column and box
Trace the column and the small box with a finger. Ask your child to check that their number does not already appear in either one.
“How did you know?”
Ask your child how they chose a number before checking the answer key. Let them try another puzzle at the same level before offering one with fewer clues.
Sudoku rules for kids
Fill each empty square with a number from 1 to 4. A number cannot repeat in the same row, column, or small 2×2 box. The thick lines mark the four boxes. Use this example to check all three rules:
For 6×6 Sudoku, use numbers 1–6. Each row, column, and 2-row by 3-column box must contain all six numbers without repeats.
- Point across the bottom row: “We have 4, 3, and 2. What is missing?”
- Check down the last column: “Does 1 fit here without repeating?”
- Trace the blue box: “Does this box now have 1, 2, 3, and 4?”
On a new worksheet, look for a row, column, or box with just one empty square. Fill it, then look again.

Show the answer and checks
The answer is 1. The bottom row is 4, 3, 2, 1. The last column is 4, 2, 3, 1. The blue box contains 4, 3, 2, 1.
Tips for parents and teachers
When your child gets stuck
Cover the rest of the page and focus on one row. Ask, “Which numbers are already here?” If they make a mistake, check the row, column, and box together. Let them erase and try again. Take a break or choose a puzzle with more filled squares if it feels frustrating.
At home or in the classroom
Model one puzzle aloud, solve the next together, then invite an independent attempt. In pairs, one child can place a number while the other explains why it fits. Praise the checking and explaining, without racing to finish the sheet.
