## Introduction

Irregular Sudoku is like the traditional Sudoku game, with one exception: the 9 squares in each row, column, and 3×3 box don’t have to contain all of the different numbers from 1-9.

This makes the game much more difficult, as each square has many more possibilities.

In this blog post, we’ll show you how to solve an Irregular Sudoku puzzle and give you some tips on how to best approach this challenging game.

Irregular Sudoku is one of the toughest variants of the popular logic puzzle.

It presents the solver with a 9×9 grid, but instead of the usual 3×3 squares in each row and column, there are sets of varying sizes and shapes.

The object is to fill in the missing numbers so that each column, row, and set of 3×3 squares contains all of the digits 1-9 exactly once.

## Techniques for Solving Irregular Sudoku

Irregular Sudoku puzzles can be quite daunting, but you can solve them in no time with a few simple techniques.

### Technique 1:

First, try identifying the rows and columns that have the most possible numbers in them.

Once you’ve done that, start by filling in those numbers and work your way out from there.

If all else fails, there’s always the backdoor method!

### Technique 2:

The 2nd thing to do is identify any squares that contain two or more of the same number.

### Technique 3:

The third trick for solving Irregular Sudoku is solving the easy squares and working your way towards the harder ones.

This is a good approach if you are stuck on a particular square and don’t know where to go next.

### Technique 4:

Another technique is to fill in the squares with the most candidates first.

This will often give you a few clues about how to solve the puzzle.

### Technique 5:

You can also use a â€świngâ€ť technique, which is when you fill in a square on one side of the grid based on the information from another square.

### Technique 6:

The most basic and straightforward approach is trial and error – trying different combinations of numbers until the puzzle is solved.

This can be a time-consuming process, but it often works well for only mildly irregular puzzles.

### Technique 7:

Another method that can be used is the ‘cross-hatching’ technique.

This approach involves dividing the grid into smaller sections and solving each section individually.

### Technique 8:

Once all sections have been solved, the individual solutions can be combined to form the complete answer.
