Sudoku Solver with a very simple GUI.
GUI is coded with Tkinter. App uses recursive algorithm with backtracking to solve Sudoku.
Fill board with numbers and click a "SOLVE" button to get the result.
To clear the whole board of Sudoku click a "RESET" button.
In the future I am going to improve this project by adding an option to solve Sudoku from the photo using OpenCV library in Python and making a better looking and more sophisticated GUI.
