    You can design a small Python game with AI using the pygame library. Below is an example of a simple Tic-Tac-Toe game where the computer uses the Minimax algorithm to play optimally, making it unbeatable.

    Steps to Build

    1. Install Pygame

    pip install pygame

    2. Create the Game Logic with AI

    import math
    import pygame

    # Initialize Pygame
    pygame.init()
    WIDTH, HEIGHT = 300, 300
    LINE_WIDTH = 5
    WHITE, BLACK = (255, 255, 255), (0, 0, 0)
    screen = pygame.display.set_mode((WIDTH, HEIGHT))
    pygame.display.set_caption("Tic-Tac-Toe AI")

    def draw_board():
    screen.fill(WHITE)
