# Sudoku Game Code in C with Source Code

You will learn how to create your own puzzles and how to solve existing ones by using computer programs with this sudoku game in C language source code. The puzzle game Sudoku is among the most well-known traditional games.

The playing grid for the game of Sudoku is made up of 99 individual squares. The first part of the game consists of 9 squares that have both rows and columns in them. Each of these nine squares is a unique grid consisting of thirty-three square areas.

In each row and column, there are a total of 9 squares. The game can be played by either one or two people, and the objective is for the players to complete the boxes in the shortest amount of time possible.

The objective of the game is to complete the squares by placing numbers in the boxes that range from 1 to 9. The fact that no number can appear more than once in any given column, row, or square is what makes the game of Sudoku so exciting.

The Sudoku game code is written in the C programming language, and it comes with a free download of the source code. Simply look for the source code that can be downloaded below, and then click the “Download Now” button.

Make sure that you have Code Blocks or another platform that supports C installed on your computer before you begin developing a calculator using the C programming language.

## Sudoku game code in C language Steps on How to Create a Project

Time needed: 5 minutes

The following is a step-by-step guide that will teach you how to create a Sudoku game code in the C programming language using source code.

• Step 1: Create a new project.

First open the code blocks IDE and click “create a new project“.

• Step 2: Choose console application.

Next, click the “console application” and after that click “next“.

• Step 3: Choose C language.

Then , choose “C language” and click “next“.

• Step 4: Name your project.

Lastly, name the project you’ve created and click “next” after that click “finish“.

• Step 5: The actual code.

Finally, we will now start adding functionality to our C Framework by adding some functional codes.

## This Sudoku Game in C Language was build and run under Code::Blocks IDE.

• This is the code to fill the board.
```for (row = 0; row < 36; row++)
for (col = 0; col < 36; col++)
data[row][col] = 0;
```
• This is the function to check if default board is broken.
```if (copy[row][col] != 0)
{
if (checkinvalid(copy, row, col) == 1)
return -1;
}```
• Function to fill in the empty space.
```for (space = 1; space <= boardrow; space++)
{```
• Function to check if it is duplicates.
`invalidflag = checkinvalid(copy, row, col);`
• The Function for determining whether a value should go into a position(Sudoku Programming in C)
```int i, j, k;
int nonetrow, nonetcol;

for (i = 0; i < boardrow; i++)```
• Function to check to check row and columns for invalid
```if ((i == row));
else if (copy[row][col] == copy[i][col])
return 1;

if ((i == col));
else if (copy[row][col] == copy[row][i])
return 1;```
• Function to actually print data into square(Sudoku Programming in C)
```if (board[row-1][col-1] != 0)
{
if ((board[row-1][col-1]) > 9)
printf(" %d", board[row-1][col-1]);
else
printf(" %d ", board[row-1][col-1]);
}```
• The Function if it has passed or go to next level
```if (invalidflag == 0)
{
status = solver(copy, 0);

if ( status > 0)
{
return status;
}

else if ( status == -1 )
return -1;
}```
• Function to start at two after the end of “rows”(Sudoku Programming in C)
```for (i = 5; i < strlen(command); i++)
boardrow = 10*boardrow + (command[i] - '0');

switch(boardrow)
{
case 4: nonetsize = 2; break;
case 9: nonetsize = 3; break;
case 16: nonetsize = 4; break;
case 25: nonetsize = 5; break;
case 36: nonetsize = 6; break;
default:
printf("Rows/columns number must be the square of an integer.\n");
boardrow = temp;
}```

## Conclusion

In a conclusion, developers have an insatiable appetite for the production of video games. It helps the developer develop their creativity while also aiding in the exploration of the fundamental notions of the language being developed.

Game designers typically limit themselves to just a few programming languages, despite the fact that there are hundreds of different languages that can be used to create games. Game designers frequently suggest C Language in order to provide players with a superior experience.
