The rule
How to play Sudoku
A standard Sudoku is a 9×9 grid divided into nine 3×3 boxes. Some squares already contain numbers. Your task is to fill every empty square so that each row, each column and each box contains the numbers 1 to 9 exactly once.
Smaller grids follow the same rule. A 4×4 puzzle uses 1 to 4 and four 2×2 boxes; a 6×6 puzzle uses 1 to 6 and six boxes of 2 rows by 3 columns.
Solving tips
How to solve a Sudoku, step by step
- Scan one number at a time. Pick a number and look at each box. If the number is missing from a box, find which squares in that box are blocked by the same number in their row or column. If only one square is left, it goes there.
- Look for nearly full groups. A row, column or box with one or two empty squares is often quick to finish.
- Use pencil marks. On medium and hard puzzles, write the possible numbers small in each square and cross them off as the grid fills up.
- Never guess blindly. Each PaperKind Printables puzzle has exactly one solution, so there is always a logical next step — even if it takes a while to spot.
- Check at the end. Compare with the solution sheet. If something is wrong, look for the first number that repeats in a row, column or box.
