How to Play Sudoku

It is a logic-based number puzzle played on a 9x9 grid. The objective is to fill each row, column, and 3x3 box with the numbers 1 to 9, ensuring that no number repeats within the same row, column, or box.

Here's a step-by-step guide on how to play it:

1. Start with an empty Sudoku grid.
2. Look for clues or numbers already provided in the grid.
3. Begin by analyzing the grid and identifying any numbers that can only fit in one particular cell.
4. Use the process of elimination to fill in the remaining cells, ensuring that each number appears only once in each row, column, and 3x3 box.
5. Continue filling in numbers and making logical deductions until the entire grid is filled.
6. Double-check your solution to ensure that all the rules of Sudoku are followed.

Strategies

1. Single Possibility: Look for cells that have only one possible number based on the numbers already filled in the same row, column, or box.
2. Elimination: Identify numbers that cannot fit in a particular cell based on the numbers already present in the same row, column, or box.
3. Naked Pairs/Triples: If two or three cells in a row, column, or box contain the same two or three possible numbers, those numbers can be eliminated as possibilities from other cells in the same row, column, or box.
4. Hidden Pairs/Triples: If two or three cells in a row, column, or box contain the same two or three possible numbers, those numbers must be present in those cells and can be eliminated as possibilities from other cells in the same row, column, or box.
5. X-Wing: Look for a pattern where two rows (or columns) each have two cells with the same two possible numbers. If these cells form a rectangle, the numbers can be eliminated as possibilities from other cells in the same columns (or rows).
