What is Sudoku?
Sudoku is a grid-based, number-placement puzzle game that is played on a 9x9 grid. The objective of the game is to fill the grid with digits so that each column, each row, and each of the nine 3x3 subgrids that compose the grid (also called "boxes", "blocks", or "regions") contain all of the digits from 1 to 9.
How to Play Sudoku:
-
Familiarize yourself with the Sudoku grid: The grid is divided into 9 rows, 9 columns, and 9 3x3 subgrids. Ensure that you can quickly identify these subgrids to apply the rules effectively.
-
Fill in the given numbers: Sudoku puzzles are often provided with some numbers already filled in. Your task is to fill in the remaining empty cells by following the rules of the game.

Follow the Sudoku rules:
- Each row must contain the digits 1-9, with no repetitions.
