Learn number placement while solving

Start by filling squares with fewer numbers and proceed steadily.

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.
