## Introduction to Sudoku

Sudoku is a number puzzle game that involves filling a 9×9 grid with numbers from 1 to 9. The goal is to fill the grid with numbers so that each row, column, and 3×3 square contains all the numbers from 1 to 9 without repeating any digit. It may sound simple, but as the grid fills up, it becomes more challenging to find the next number to place.

The origins of Sudoku can be traced back to late 18th century France, where it was known as “Number Place.” However, the modern version of the game that we know today was created in the late 1970s by a puzzle designer named Howard Garns. It wasn’t until the 1980s when Sudoku became popular in Japan, and from there, it spread throughout the rest of the world.

Today, Sudoku is one of the most popular puzzle games in the world, with millions of players enjoying it on a daily basis. It’s a game that requires focus, strategy, and patience, making it the perfect pastime for those looking for a mental challenge.

### The Rules of Sudoku

Before we dive into the strategies and tips, let’s go over the basic rules of Sudoku.

Rule Description
9×9 Grid The game is played on a 9×9 grid.
Numbers 1-9 The grid is filled with numbers from 1 to 9.
No Repeating Digits Each row, column, and 3×3 square must contain all the numbers from 1 to 9 without repeating any digit.
Starting Numbers Some numbers will already be provided in the grid to give you a starting point.

## How to Play Sudoku

Now that we’ve covered the basics let’s dive into how to play Sudoku.

### Step 1: Understand the Grid

The first step in playing Sudoku is understanding the grid. As we mentioned earlier, the game is played on a 9×9 grid, which is divided into 3×3 squares. Each square, row, and column must contain all the numbers from 1 to 9 without repeating any digit.

### Step 2: Look for Clues

Some numbers will already be provided in the grid to give you a starting point. These numbers are known as “clues,” and they are essential in solving the puzzle. Look for rows, columns, and squares that already have several numbers filled in, as these will help you determine which numbers are missing.

### Step 3: Use Logic to Determine Missing Numbers

Once you have some clues to work with, it’s time to start using logic to determine which numbers are missing. Start with the rows, columns, and 3×3 squares that have the least number of numbers filled in. Look for numbers that are missing and try to eliminate possibilities using the clues already provided.

### Step 4: Keep Track of Possibilities

As you start filling in numbers, keep track of the possibilities for each cell. This will help you avoid repeating digits and narrow down the choices for remaining cells.

### Step 5: Use Strategic Guessing

Once you’ve filled in as many cells as you can using logic, it’s time to start guessing. However, be strategic in your guessing. Look for cells that have two or three possible numbers and make an educated guess based on the surrounding cells. If your guess is correct, it will lead to a chain reaction of numbers, helping you fill in more cells. If your guess is incorrect, backtrack and try again.

### Step 6: Repeat the Process

Keep repeating steps 3-5 until you’ve filled in the entire grid. Sudoku is all about trial and error, so don’t be afraid to make mistakes and learn from them.

### Step 7: Check Your Work

Once you’ve filled in the entire grid, double-check your work to make sure there are no repeating digits in any row, column, or 3×3 square. If everything checks out, congratulations! You’ve solved the Sudoku puzzle.
