If you’ve ever played a puzzle game, you’ve undoubtedly reached the terrible point where you don’t know how to solve it. Sometimes you erase and begin again, or perhaps you give up. Regardless of your skill level with Sudoku, you’ve probably wondered if there are ways to increase your performance.

Fortunately, there are tactics you can employ to boost your odds of solving free sudoku puzzle games. It only requires practice and research to determine how the techniques function. If you want to improve your performance and give yourself some well-deserved pats on the back, you’re in excellent hands here. We discuss the top advanced Sudoku strategies. Let’s get started!

1. X-Wing strategy

The X-Wing approach is one of the most efficient ways to solve the Sudoku. It is also crucial to note that this strategy can be applied to several intermediate sudoku levels despite being uncommon in certain circumstances.

With this strategy, the player will focus on parallel columns and rows. As a gamer, you will not pay much attention to squares. The purpose of the X-Wing method is to eliminate probable numbers and erase some of the initial pencil traces you made while solving the puzzle.

Examine the rows carefully for pencil marks that appear twice. Next, couple this row with a row that runs parallel to it. Please note that the pencil marks in the two places should be identical.

The X-Wing strategy requires a great deal of consideration. Yet, it functions exceptionally well. But it is not the most effective strategy for beginners. Nonetheless, it is the best way to improve your Sudoku-solving skills. Instead of focusing solely on one column, row, and square, you will acquire the information and skills necessary for progression. This strategy may allow you to view things more clearly.

2. Swordfish strategy

The Swordfish Method derives its name from its appearance. Occasionally, the swordfish technique produces a pattern that resembles a swordfish. The Swordfish can be a very effective method, but it can be difficult to locate. Like the X-Wing Strategy, the Swordfish aims to reduce the prospective population. The X-Wing Method examines two rows, whereas the Swordfish Technique examines three rows.

Begin by identifying a number that appears twice in a single row and three times in the same three columns. Then, visualize lines traversing the rows and columns. You may eliminate the potential number from any square containing only one line but not both.

The Swordfish strategy is one of the most sophisticated and difficult methods for completing free Sudoku puzzle games. It is best suited for experienced Sudoku players who thoroughly understand how grid patterns function. This strategy may not work if you are a beginner at Sudoku because you cannot recognize patterns fast, which will hinder you from solving the puzzle. Considering how beginner-friendly the X-Wing approach is, you may consider using it.

3. The XY-Wing/ Y-Wing strategy

The XY-Wing/ Y-Wing strategy is a method for eliminating possible integers (just like the X-Wing and Swordfish strategies). The XY-Wing technique necessitates three blocks containing a pair of numbers partially shared by all three blocks. Sounds strange? Indeed, it is. If your pairs consist of AB, BC, and CA, then the middle block will have one number from every one of the other two pairs.

After locating your three blocks, you can link them using a single line. This is where the Y in XY-Wing comes from, as the line often resembles the top of a Y. You must now use logic to determine which rows, columns, and squares have potential integers that can be eliminated.

4. The Forcing Chain

This is one of the most effective and straightforward methods for solving free Sudoku puzzle games. Yet, its implementation can be rather challenging. This is due to the high focus level required and the outcome’s unpredictability. If successful, this strategy will supply the player with the solution to a single cell.

The grid must have cells with only two digits for this method to work. You select one and begin comparing the differences in the puzzle when both digits are applied to that particular cell. This strategy aims to identify a cell that can deliver the same result regardless of the digit used. Then, it will be the solution to the issue.
