Download Kids 6 × 6 sudoku (PDF)How do you play sudoku?
Fill every empty square so that each row, each column and each outlined box contains every number exactly once — 1 to 9 on a 9 × 9 grid, 1 to 6 on a 6 × 6 grid. The printed numbers are clues and never change.
- Start with a row, column or box that is missing only one or two numbers.
- For each empty square, rule out the numbers already in its row, column and box.
- Write small pencil marks for the numbers that are still possible, and rub them out as you go.
What makes these sudoku puzzles large print?
Each 9 × 9 puzzle fills the 7.5 in width inside half-inch margins, so every square is about 0.83 in wide and the clues are printed at about 41 pt bold. Thick lines mark the 3 × 3 boxes and thin lines the squares, which leaves plenty of room for pencil marks. Print at actual size on US Letter, or choose Fit on A4.
How are the difficulty levels different?
Easy puzzles here start with 39–40 clues, medium with 33–34 and hard with 28–32. Fewer clues means more steps before each number is certain. Every puzzle can be solved by logic alone; none need guessing. The 6 × 6 kids set uses numbers 1–6 and 2 × 3 boxes.
Can I make my own sudoku book?
Yes. These puzzles were made with the DT Labs sudoku generator, which also makes 4 × 4, 16 × 16, Sudoku X and Samurai puzzles, ramps difficulty through a book and exports a KDP-ready PDF with answers and a commercial licence. Our guide how to make a sudoku book for KDP covers page count, trim size and pricing.
