# Sudoku: Sharpen Your Brain with This Classic Puzzle

Sudoku is a popular logic-based number-placement puzzle. The objective is to fill a 9×9 grid with digits so that each column, each row, and each of the nine 3×3 subgrids contains all of the digits from 1 to 9.

Sudoku is a great way to exercise your brain and improve your problem-solving skills. It is also a fun and relaxing activity that can be enjoyed by people of all ages.

## How to Play Sudoku

To play Sudoku, you need a 9×9 grid with some numbers already filled in. These filled-in numbers are called clues. The goal is to fill in the rest of the grid by using logic and deduction.

Here are the basic rules of Sudoku:

• Each row must contain the numbers 1 through 9.
• Each column must contain the numbers 1 through 9.
• Each of the nine 3×3 subgrids must contain the numbers 1 through 9.

To solve a Sudoku puzzle, you can use a variety of techniques. One common technique is to look for numbers that can only go in one possible square. For example, if a row has the numbers 1, 2, 3, 4, 5, 6, 7, and 8, then the remaining square in that row must contain the number 9.

Another technique is to look for numbers that are missing from a row, column, or subgrid. For example, if a row is missing the numbers 2 and 5, then you know that those numbers must go in the remaining two squares in that row.
