How to Play Sudoku
Sudoku is a logic-based number puzzle. The goal is to fill a 9×9 grid with digits so that each column, row, and 3×3 section contains all numbers from 1 to 9.
Basic Rules:
- Each row must contain the digits 1-9 with no repetition
- Each column must contain the digits 1-9 with no repetition
- Each 3×3 box must contain the digits 1-9 with no repetition
Pro Tips:
- Start with rows, columns, or boxes that have the most numbers filled in
- Use pencil marks to track possible candidates for each cell
- Look for "hidden singles" - cells where only one number can fit
