Sudoku

This Sudoku game is a project written in Python. This project implements Python GUI, Object-Oriented Programming principles, and backtracking.

Python

As this project is written in Python, I have chosen Pygame to enable user interaction.

Object-Oriented Programming

This project uses multiple principles of Object-Oriented Programming to help simplify the code, including abstraction, inheritance, and polymorphism.

Backtracking

The solve method of this project utilized a backtracking algorithm to recursively test for correct choices for each available spot.

How to play

• At the main menu screen, select your difficulty.
• To input a number, select the square you want and input a number.
• To remove a number, select a square and hit the DELETE key.
• The check button will show you if there are any conflicting inputs.
• The solve button will show the program using backtracking to test different inputs.
• The new game button will send you back to the main menu screen.
