Tic-Tac-Toe Game with AI

This is a classic Tic-Tac-Toe game implemented using Python and Pygame, where you can play against an AI opponent. The AI has three difficulty levels: Easy, Medium, and Hard, providing different levels of challenge for players. The game also includes a graphical interface with smooth animations and pop-up messages indicating the game result.

Features:

Single-Player Mode: Play against an AI opponent with varying levels of difficulty.

AI Difficulty Levels:

Easy: The AI makes random moves, providing an easy challenge. Medium: The AI alternates between random moves and optimal moves, making it moderately challenging. Hard: The AI uses the Minimax algorithm to always play optimally, providing the toughest challenge. Graphical User Interface (GUI): Built using Pygame, with clear graphics for the grid, X's, and O's. Result Pop-Up: Displays a message indicating the winner or if the game is a draw. Smooth Animations: Updates the board dynamically after each move.

How to Play:

Choose the Difficulty: When the game starts, a difficulty selection screen allows you to pick between Easy, Medium, or Hard difficulty. Make Your Move: Click on any empty cell to place your 'X'. The AI will then make its move. Win the Game: Try to get three of your marks (X's) in a row—horizontally, vertically, or diagonally—before the AI does. Game Over: The game will display a pop-up message indicating whether you won, lost, or if it was a draw.

Requirements:

Python 3.x , Pygame library

How the AI Works

The AI uses different strategies depending on the difficulty level:

Easy: Makes random moves without any strategy. Medium: Chooses between making a random move or using an optimal strategy. Hard: Uses the Minimax algorithm, which simulates all possible moves to find the best move for the AI, making it unbeatable.

Future Improvements:

Add two-player mode for playing with a friend. Enhance the GUI with sound effects and animations. Add a scoring system to track wins, losses, and draws over multiple rounds. Implement a smarter AI that adapts its strategy over time.
