Check basic rules while solving
Use pencil marks to track possible candidates.
Tips for Solving Sudoku
- Start with squares with fewer numbers: Begin with rows, columns, or blocks that already have more numbers filled; fewer candidates make it easier to solve.
- Pencil marks (notes): For beginners, write possible numbers in small font in empty squares for reference.
- Review: If stuck, check for duplicate numbers or rule violations.
- Basic rule: Do not repeat the same number in the same row, column, or 3x3 block.
