How to Play Sudoku: The Basic Rules

If you are new to the game, the rules of Sudoku are straightforward, making it highly accessible yet deeply engaging.

The game is played on a 9x9 grid, which is divided into nine smaller 3x3 subgrids. Some cells are already filled with numbers at the start of the game. Your goal is to fill the remaining empty squares so that:

• Each horizontal row contains the numbers 1 through 9 without repetition.

• Each vertical column contains the numbers 1 through 9 without repetition.

• Each of the nine 3x3 subgrids contains the numbers 1 through 9 without repetition.

The key to solving a puzzle is logical deduction. No math or calculation is required—only patience and observation.
