What are Sudoku Puzzles?

Sudoku puzzles are a fun and challenging past time for the enthusiast of brain puzzles. The game involves squares with nine squares inside each square. The squares are boxed together where there is numbers from 1 to 9 in a row as well. Each puzzle only has a few numbers already in place to help you solve the puzzle by filling in the missing numbers. There are many methods to help you solve a sudoku puzzle. The following are the two methods of solving a sudoku puzzle using pairs and singles to solve it.

Using the Pairs Method To Solve a Sudoku Puzzle

One of the methods to solving a Sudoku puzzle is to use the open pairs method. This method involves looking for existing pairs in the puzzle so you know where you can add in another number into the puzzle. This is one of the best things to do first when looking for where numbers can go. Even if you can’t add in another number right away by using this method, you can take note of where you can put a number using this method until you have solved more of the puzzle.

How to Use the Singles Method to Solve a Sudoku Puzzle

The singles method is another way to solve a Sudoku puzzle. This method is a bit more of guesswork compared to the pairs method, but it involves taking educated guesses. This method involves looking at the rows of numbers in the sudoku puzzle and trying to fill the row up with numbers 1 to 9. This can be easy in some instances if enough of the puzzle is filled in. Or it may be a bit challenging and you’ll have to do quite a bit of guesswork on it until you progress farther into the puzzle.

These methods of solving a sudoku puzzle will help you to become a pro at working on these fun brain puzzles. The pairs method is a bit more effective to quickly solve a puzzle and the singles method is good for helping to slowly patch in numbers until you are farther along in the puzzle to fill in more of it. Remember, there are other methods and some methods work better than others for some people. Just choose the method that works best for you to solve the puzzle in an effective way.
