Sudoku puzzles are played on a 9×9 grid, divided into nine 3×3 subgrids called “boxes.” The objective is to fill the grid with numbers 1 to 9, ensuring that each row, column, and box contains unique numbers. - Rules and Guidelines:
To solve Sudoku puzzles, you must adhere to the following rules:

c. Each box must have the numbers 1 to 9 without repetition. - Basic Strategies for Solving Sudoku:
Here are some essential strategies to help you solve Sudoku puzzles effectively:
a. Look for missing numbers: Scan rows, columns, and boxes to identify empty cells and determine which numbers are still missing.
b. Use crosshatching: Examine rows and columns that intersect at a specific cell to eliminate numbers that cannot go in that cell.
c. Employ “naked pairs” and “hidden pairs”: Look for pairs of numbers that can only go in two cells in the same row, column, or box. If a number can only be placed in one cell, it’s a “hidden pair.”
d. Utilize “x-wings” and “swordfish”: These advanced techniques involve finding patterns in three or more rows or columns to eliminate numbers in specific cells.

Once you’ve mastered the basic strategies, you can move on to more challenging techniques such as “XY-wings,” “coloring,” and “Turbotriplets.” These methods require advanced logical reasoning and are best suited for experienced Sudoku players. - The Big Book of Sudoku:
