Sudoku game and solver in one. Backtracking algorithm using pygame.

There is a console version of sudoku backtracking algorithm (sudoku.py) - just a solver.

Second attempt was to create GUI with help of pygame. It is possible to play as well as to see how the backtracking algorithm works in practice.

After pressing SPACE and waiting for a bit we get a solution!

Got insipired by YouTuber Tech with Tim and made my own version.
