Sudoku rules
Fill the 9×9 grid so that every row, every column and every 3×3 box contains the numbers 1 to 9 exactly once. Some numbers are already given – use logic to find the rest. No maths is needed, and there is never any guessing in a well-made puzzle.
Tips for solving printed Sudoku
- Use a pencil and write small candidate numbers in the corners of empty squares.
- Start with the fullest areas. Rows, columns or boxes with many numbers are the easiest to complete.
- Scan for each number. Pick one number and check where it can still go in each box.
- Check the answer key only when you are finished – or when you are truly stuck.
Great for home, school and travel
