Sudoku Game Development with Python and Pygame

# Introduction

In this project, we will create a Sudoku game using Python and the Pygame library. The game will generate a Sudoku grid of the specified difficulty level and let players solve the puzzle by filling in the empty cells with numbers. The game will provide features like selecting difficulty, highlighting selected cells, and checking if the grid is complete.
