📖 How to Play Sudoku

Before we dive into the specifics of how to play sudoku, let’s first understand the basics. Sudoku is a puzzle that is played on a grid. The grid is usually 9×9, but it can also be 6×6 or 4×4. The goal of sudoku is to fill the grid with numbers from 1 to 9 (or 1 to 6 or 1 to 4 depending on the grid size) so that each row, column, and 3×3 box contains all the numbers from 1 to 9 (or 1 to 6 or 1 to 4).

Step 1: Understand the Grid

The first step in playing sudoku is to understand the grid. As we mentioned earlier, the grid is usually 9×9. This means that it’s made up of 81 squares that are divided into 9 rows and 9 columns. The rows are numbered from 1 to 9, and the columns are labeled from A to I. Each square is identified by its row and column label. For example, the square in the first row and first column is labeled as 1A.

Step 2: Know the Rules

Now that you understand the grid let’s move on to the rules of sudoku. The rules are pretty simple. You must fill in every square of the grid with a number from 1 to 9 (or 1 to 6 or 1 to 4). Each row, column, and 3×3 box must contain all the numbers from 1 to 9 (or 1 to 6 or 1 to 4). You can only use each number once in each row, column, and 3×3 box.

Step 3: Start Filling in the Grid

Now that you know the rules let’s start filling in the grid. Start by looking for squares that only have one possible number. For example, if a square has rows and columns that are already filled, you can easily identify its value. Once you’ve filled in all the squares that have one possible number, start looking for squares that have a limited number of choices. This process is called “pencil marking.” Use your pencil to write down all the possible numbers in the square.

Step 4: Repeat Until the Grid is Filled

Continue filling in the grid by looking for squares that only have one possible number and using pencil marking to find squares that have limited choices. Repeat this process until the entire grid is filled. And that’s it! You’ve successfully completed a sudoku puzzle.

If you’ve mastered the basics, you can move on to advanced strategies. Some of the most common strategies include:

• Elimination: This involves looking for rows, columns, or 3×3 boxes that only have one possible number.
• Subsets: This involves looking for groups of squares that only contain a limited number of possibilities.
• X-Wing: This strategy involves identifying rows or columns that have only two possible squares for a particular number.

Step 6: Tips and Tricks

Here are some tips and tricks to make playing sudoku easier:

• Take breaks if you get stuck. Coming back to the puzzle with fresh eyes can help you see things you might have missed before.
• Use a pencil so you can easily erase mistakes.
• Focus on one part of the grid at a time.
• Look for patterns in the puzzle.
