What is Sudoku?

Sudoku is a logic-based number-placement puzzle that has gained immense popularity worldwide. The objective is simple: fill a 9x9 grid so that each column, each row, and each of the nine 3x3 subgrids contain all the digits from 1 to 9. This game not only provides entertainment but also promotes critical thinking and problem-solving skills.

How to Play Sudoku

Playing Sudoku involves understanding its basic structure and rules. Here’s how to start:

1. Familiarize yourself with the 9x9 grid layout, which is divided into 3x3 boxes.
2. Identify the given numbers in the puzzle. These numbers serve as your starting point.
3. Use logic to determine where the remaining numbers belong, ensuring that each number from 1 to 9 appears only once per row, column, and box.

Basic Sudoku Rules

• Each number must appear only once in each row.
• Each number must appear only once in each column.
