C-Sudoku is a program written in C programming language.

It was created in continuation of another fun project the

Sudoku Solver

C-Sudoku generates sudoku riddles, in four levels of difficulty.

You can solve these riddles in CLI(command-line interface).

From a simple menu, the user can :

• Play the game,

• See the solution of the game,

• Save the riddle in a simple txt file so that it can be printed,

• Generate a new riddle.

Using the terminal interface, after you clone the folder and change directory into it:

	git clone https://gitlab.com/christosangel/c-sudoku.git

	cd c-sudoku

you will need to compile c-sudoku.c:

	gcc c-sudoku.c -Wall -o c-sudoku

After that, all you need to need is run the executable:

	./c-sudoku

You will have to wait a couple of seconds for the machine to calculate a

new riddle (the speed depends on the processing capability of your hardware).

You will be prompted to give your prefered level of difficulty:

After that you can select between playing or saving the riddle, generating

a new one, or exiting:

If you select Play, you can enter the data (row number, column number and value, in a specific format 0-9/0-9/0-9, e.g. 3/5/7:

When you solve the riddle, you will be given your time:

• The colors of the sudoku matrix are customisable:

• The difficulty level is also quite arbitrary, and depends on how many numbers are missing.

  The difficulty levels can also be altered:

ENJOY!
