Sudoku is a logic puzzle with numbers.
The rules are simple:
- The game board is a 9×9 grid.
- You need to fill empty cells with numbers from 1 to 9.
- Each number from 1 to 9 must appear only once in each row, column, and 3×3 square.
How to start:
- First, look for rows, columns, or squares that are missing only one number.
- Check which numbers are already nearby and eliminate them.
- Fill in the most obvious cells first, then move on to more complex ones.
