Here’s an extended version of the README.md file with more detailed descriptions of the gameplay, AI logic, and setup.

Tic-Tac-Toe Game

This project is a Python-based Tic-Tac-Toe game built with Pygame. It provides a simple, fun way to experience classic gameplay with options for both single-player and two-player modes. The game offers basic AI to play against in single-player mode and is structured for easy customization or further development.

Features

• Single Player: Play against an AI with basic decision-making.
• Two Players: Play with a friend on the same computer.
• Simple UI: A clean, interactive user interface built with Pygame for easy gameplay.
• Replay Option: Option to replay after each game.
• Cross-platform Support: Works on Windows, macOS, and Linux with Pygame.

Game Modes

1. Single-Player Mode:

   • In this mode, you play against the computer's AI.
   • The AI makes moves to block the player and attempts to win, but uses basic logic rather than advanced strategies, making it accessible and enjoyable for casual players.

2. Two-Player Mode:

   • Play against a friend, taking turns on the same computer.
   • A great way to enjoy Tic-Tac-Toe in a classic face-to-face setting.

Installation

To get started, ensure Python and Pygame are installed on your system.

Step 1: Clone the repository

Clone this repository to your local machine:

git clone https://github.com/proutkarsh3104/Tic-Tac-Toe.git
cd Tic-Tac-Toe

Step 2: Install dependencies

Install Pygame using pip:

pip install pygame

Step 3: Run the game

Run the game with the following command:

python main.py

Usage

• Run the game: After installation, use python main.py to start the game.
• Choose a mode: The game will prompt you to select either single-player or two-player mode.
• Exit: Close the game window or follow in-game prompts to exit.

How to Play

• Objective: The objective is to align three of your marks (either "X" or "O") in a row, column, or diagonal on a 3x3 grid.
• Gameplay:
  • In two-player mode, players alternate turns.
  • In single-player mode, the player goes first, then the AI takes its turn.
• Winning and Draws:
  • A player wins by completing a row, column, or diagonal with their marks.
  • If the grid is completely filled with no winner, the game is a draw.

Project Structure

• main.py: The main script that initializes the game, handles user input, and manages the game loop.
• assets/: (Optional) A folder for any images, sound files, or other assets used in the game.
• README.md: This documentation file.
• LICENSE: License information for the project.

AI Logic

The AI in this game uses basic decision-making logic to determine its moves. It follows these steps:

1. Win Checking: If there’s an immediate winning move available, the AI takes it.
2. Blocking: If the player is about to win in the next move, the AI will block them.
3. Random Move: If no immediate win or block is required, the AI picks an available spot randomly.

This makes the game AI relatively simple and beginner-friendly, without being overly predictable.
