## The Basics of Sudoku

Sudoku is played on a 9×9 grid, divided into nine 3×3 regions. The objective is to fill in the empty cells with numbers from 1 to 9, ensuring that each row, column, and region contains all digits without repetition. Remember these essential rules as you progress through the solving guide.

## Step-by-Step Sudoku Solving Guide

### Step 1: Scanning the Grid

Begin by scanning the entire grid for any numbers that are already filled in. Look for rows, columns, or regions with the most filled cells. These initial placements will provide clues for the rest of the puzzle.

### Step 2: Identifying Naked Singles

Search for cells that have only one candidate left. These are known as “Naked Singles.” Whenever you find a Naked Single, fill in the number immediately. This simple technique can solve a significant portion of the puzzle.

### Step 3: Using Crosshatching Technique

Crosshatching involves checking each row and column to identify potential placements for missing digits. Look for rows or columns with only a few missing numbers. Use the process of elimination to determine the correct numbers for those cells.

### Step 4: Finding Hidden Singles

Look for cells that have a number unique to their row, column, or region, but the number is not obvious at first glance. These are called “Hidden Singles.” Identifying Hidden Singles can help you fill in more numbers and progress further in the puzzle.

### Step 5: Applying Advanced Techniques

If the puzzle becomes more challenging, you can employ advanced techniques like Naked Pairs, Naked Triples, X-Wing, Swordfish, and other strategies. These techniques involve identifying patterns of candidate placements and using them to eliminate possibilities in specific cells.
