Sudoku has just three simple rules, but they create endless logical challenges.
Understanding the Concept
Rule 1: Each row must contain the digits 1-9 with no repetition.
Rule 2: Each column must contain the digits 1-9 with no repetition.
Rule 3: Each 3×3 box must contain the digits 1-9 with no repetition.
That's it! These three rules are all you need to know to solve any Sudoku puzzle.
Every valid Sudoku puzzle has exactly one solution that can be reached through logical deduction.
Pro Tips

- •If a number appears in a column, it cannot appear again in that same column
- •If a number appears in a box, it cannot appear again in that same box
