Sudoku with GUI

A desktop Sudoku puzzle game with its own GUI, different difficulty levels and a tiles detection system. This game also features a Sudoku Solver so the user can input any box and the algorithm will output its solution if it is solvable.

This was the first big project with a UI that I made before tweaking with HTML and CSS. I learned a lot of things creating this, from how backtracking algorithms work to how to create a time counter with Python and Tkinter. This Sudoku took me several weeks to finish and I'm very proud of the result.
