Basic Rules
Sudoku is a number-placement game played on a 9×9 grid, divided into nine 3×3 sub-grids. The goal is to fill each row, column, and 3×3 box with numbers from 1 to 9 without repeating any number within the same row, column, or box.

- Start with the Given Numbers: Identify the numbers already placed in the grid and use them as clues.
- Scan Rows and Columns: Check each row and column for missing numbers and determine where they logically fit.
- Use the Process of Elimination: If a number can only fit in one spot, place it there.

Advanced Solving Techniques
