Let's dive in and master the art of Sudoku!

Understanding the Sudoku Grid

The Sudoku grid consists of a 9x9 square divided into nine smaller 3x3 squares. To solve the puzzle, you must fill in each cell with a number from 1 to 9. The goal is to ensure that each column, each row, and each of the nine 3x3 subgrids contains all numbers from 1 to 9 without repetition.

Step 1: Analyze the Clues

Begin by analyzing the initial clues provided in the puzzle. These are numbers already filled in the grid. Take a moment to scan the entire grid and identify any numbers that are given as clues. These clues will serve as your starting point.

Step 2: Look for Single Candidates

Once you've analyzed the clues, examine each row, column, and subgrid to identify cells with only one possible candidate. These are cells that are surrounded by numbers that have already been placed. When you find a cell with a single candidate, confidently fill in that number. Repeat this process until no more single candidates can be found.

Step 3: Use Crosshatching and Elimination

If there are still empty cells after filling in the single candidate cells, it's time to employ crosshatching and elimination techniques. Start by focusing on one number at a time. Examine each row and column within a subgrid and identify the missing numbers. By eliminating numbers already present in the same row, column, and subgrid, you can determine the possible locations for the missing number.

For example, if a row already contains the numbers 1, 2, 4, 6, 8, and 9, and there is only one empty cell remaining in that row, you can confidently determine that the missing number must be a 3 or a 7.

Repeat this process for each number until no more eliminations can be made. It may take some practice to become comfortable with this technique, but with time, you'll develop a stronger sense of logic and pattern recognition.

Step 4: Apply the "Only Choice" Rule

The "Only Choice" rule comes into play when a number can only be placed in one particular cell within a row, column, or subgrid. Look for situations where a number is missing from a particular row, column, or subgrid and can only fit in one location based on what is already present. Place the number in that cell and continue solving.

Step 5: Repeat and Refine

Continue repeating Steps 2 to 4 until the puzzle is complete or until progress stalls. Sudoku puzzles often require a combination of techniques to solve. As you gain more experience, you'll become familiar with different patterns and logical deductions that can be applied to various situations.
