**Understanding Sudoku**
Sudoku is a popular logic-based puzzle game that has captivated puzzle enthusiasts around the world. The game is played on a 9×9 grid, which is divided into nine 3×3 subgrids, called regions. The objective is to fill the grid with numbers so that each row, each column, and each region contains all of the digits from 1 to 9. Here’s a basic overview of how to play Sudoku.
**How to Start**
1. **Grid Layout**: Begin by looking at the grid. Some cells may already contain numbers. These are called givens and provide clues for solving the puzzle.
2. **Place Numbers**: Use logic to determine which numbers can be placed in the empty cells. Remember that each row, column, and region must contain all digits from 1 to 9 without repetition.
3. **Process of Elimination**: If a cell has only one possible number, place it in the cell. Continue this process for all empty cells until the grid is filled.
