# How to Make a Sudoku Puzzle: A Step-by-Step DIY Guide

Sudoku is one of the most intriguing number-based puzzles to solve since it requires a range of approaches and strategies.

You can create a sudoku puzzle in a variety of methods, including with the aid of software that generates sudoku automatically based on algorithms or manually.

Sudoku's mental skills tests are one of the reasons for its widespread appeal. It is, in essence, a basic puzzle with a simple design and clear and straightforward principles that are free of hidden traps. Despite this, children and adults of all ages are enthralled by the fun challenges they pose.

Today, we're going to go over how to make a sudoku puzzle and some tips to ensure it's enjoyable.

## Can You Make Your Own Sudoku?

Sudoku is a pleasant way to spend your morning or to pass the time on your commute to work, and it becomes even more enjoyable once you learn about making your own sudoku. It might be difficult to design your own puzzle, but it will offer you a new appreciation for the game.

When learning how to make sudoku, three crucial criteria should be satisfied. The first and most apparent is that there should only be one solution to the puzzle. While it's possible to create your own sudoku puzzle with multiple resolutions, this detracts from the strategies that sudoku enthusiasts employ and find enjoyable.

The second requirement about making a sudoku we need to satisfy is that all of the problems we post must have a logical solution. Most people dislike the idea of having to guess since it appears to defeat the purpose of a logic puzzle, and we agree with this viewpoint.

Note that the word 'guessing' has a negative connotation attached to it. However, in one sense, guessing is rational since it is algorithmic and therefore deterministic. After all, with enough guesses, you've conducted a form of deductive reasoning. You just took the long way. Despite this reasoning, most players find that guessing is an illogical strategy since it is slow and leads to a lot of erroneous routes. In the end, the problem solver seeks ways that will ensure that a deduction is valid and that they may confidently set a number or eliminate a contender.

The third criterion is one of aesthetics. All of the clues should be symmetrical to some extent, usually in the middle of the board. The distribution of clues should be done strategically.

So, you can certainly make a sudoku puzzle, but you want to keep these guidelines in mind if you hope other puzzle-solvers will enjoy it.

### DIY: How to Make a Sudoku Puzzle

Today, we're going to focus on how to create a sudoku puzzle by hand. While this guide will cover the manual process, don't be afraid to turn to digital means to learn how to make your own sudoku. Use an online generator if tackling a sudoku puzzle by hand becomes too difficult. You'll still be able to adjust the difficulty and quantity of clues, but you won't have to put in nearly as much effort. Several websites may assist you in creating and checking puzzles.

There are millions of possible solutions when developing a sudoku game from scratch. The intriguing part about this is that the challenge is always 'solved' throughout the construction process from the designer's perspective. When you lock the initial number, the rules spread over each square, resulting in a new solution depending on that lock. You're limiting the number of viable solutions (configurations) when you lock a number.

Here are some easy steps on how to make a sudoku puzzle:

### Set up Your Grid

First, to create sudoku puzzle grids, draw a huge square using your pencil and ruler. If you have a sudoku book on hand, tracing an existing problem to establish a consistent form and size is also a good idea.

To begin your grid, nine smaller squares are created by dividing the huge outer square into nine smaller ones. Three squares should be in the top row, three in the middle row, and three in the bottom row, with three evenly spaced lines across the square and three evenly spaced lines down the square. If you want to ensure your lines are straight, use a ruler.

Ensure it's right by comparing it to existing sudoku puzzles. You'll need to divide the square into nine smaller squares, then divide those squares into even smaller grids. Draw three evenly spaced lines across each square using your pencil and ruler, then three equally spaced lines down each square.

**Note:** If you want to create a sudoku without having to recreate the grid, you can do so by making duplicates by scanning or photocopying the board.

### Developing a Solution

Begin working on a solution for your problem with a pencil. Work through each number in order to ensure that your solution is correct. Remember how the game works, or you'll come up with an inaccurate answer.

Keep the rules in mind; to win a game of sudoku, the player must fill the grid with numbers 1-9 in each row, column, and 3x3 box.

Begin by putting in the number '1.' Each 3x3 box, each row, and each column should have a number '1.' Make sure no two numbers '1' appear in the same column, row, or 3x3 box.

Now it's time to move on to number two. Begin by putting a '2' in each column, row, and 3x3 square.

Carry on with each number in order. Continue to add the numbers to each row, column, and 3x3 box. The boxes will get easier to fill as you fill in more numbers since fewer places are available.

### Backtracking

It's possible that coming up with a solution will be difficult. You can quickly get yourself into a situation where you can only fill a row or column with duplicate numbers. If you get stuck, delete a couple of the problematic numbers and restart the section.

### Review Your Solution

Check for duplicate numbers to ensure that your solution is right. It may take some time to check through each 3x3 block, row, and column, but make sure they all include the numbers 1-9 and no duplicates. Use an online sudoku solver if you don't want to do it by hand. You're ready to add the finishing touches after you're certain it's correct.

### Choosing the Level of Difficulty

Now it's time to decide on the difficulty level. Here are a few tips to keep in mind when setting the grade:

For starters, if there are 10 squares that may be answered independently of one another, this problem is plainly easier, at that moment, than one in which each solution is contingent on you obtaining the preceding ones in a particular order. As a result, a measure of difficulty may be derived only by counting the number of possibilities to solve at all stages of the game. The eye and mind can only deal with one chance at a time, and if it is taken, a number is assigned, and the board must be re-checked to discover the consequences. When there are few or just one chance to make a proper deduction, a 'bottleneck' occurs, making the puzzle more complex.

The second metric is the type of strategy required to recognize an opportunity. For example, a basic problem will just require the 'scanning' approach — simply looking for cells with only one potential number. It's certainly a harder problem if you have to start scribbling notes to figure out where a number may belong. Many tactics need a thorough understanding of all remaining candidates.

### Remove Numbers

Now that you have an idea of how hard you want to create your sudoku puzzle, begin deleting one number from each column, row, and 3x3 square with an eraser. The more you delete, the more complex the puzzle becomes to solve, so consider how difficult you want it to be. If you change your mind, you'll be able to regain your hints by softly erasing them. Also, save a duplicate of your solution for future reference.

### Examine Your Puzzle to Ensure There Is Only One Solution

Check to see if your puzzle is solvable. Work through the problem with each digit you remove to ensure it can still be completed. Make that your player can still fill in the gaps with the clues supplied and that there are no spots with inadequate clues. Replace the clues you eliminated and attempt removing others if you find it too challenging.
