View Project
Project Details

This project is an interactive Checkers game powered by an AI opponent. This project features a sleek user interface with turn-based gameplay, where users can challenge an AI opponent that makes optimal moves based on implemented strategies. The project is developed using a React frontend and Flask backend, making use of AI algorithms to simulate intelligent gameplay.

Key Features
  • Interactive Gameplay: A visually appealing Checkers board with drag-and-drop functionality for piece movement.
  • AI Opponent: An AI player that computes optimal moves using alpha-beta pruning, ensuring challenging gameplay.
  • Real-time Game State Updates: The board state is updated after every move, keeping track of player pieces and remaining moves.
  • Minimax Search with Alpha-Beta Pruning: Uses the minimax algorithm with alpha-beta pruning to optimize move choices by systematically evaluating game states and trimming unnecessary branches, minimizing search time.
  • State Evaluation and Node Ordering: Implements heuristics for efficient state evaluation and reordering of nodes, helping the AI prioritize promising moves and explore the game tree effectively.
  • Caching and State Reuse: Caches evaluated states to avoid redundant calculations, allowing faster game responses and reducing overall memory usage.
  • Interactive and Responsive User Interface: Features a visual board that updates in real-time with user and AI moves, allowing players to play against the AI and observe optimal moves in the endgame. UI is optimized for desktop and mobile devices.
  • Cross-Platform Compatibility: Designed with a Flask backend and React frontend, ensuring smooth interaction and enabling deployment across various environments.
Technologies Used
  • Frontend Development: The game interface is crafted using React and Vite, providing a fast and optimized development environment with real-time UI updates. React’s component-based architecture enables modular design, making it easy to manage game states and interactivity. Styling is done using CSS for a polished, accessible interface that adapts smoothly to user inputs.
  • Built with Flask and Flask-CORS, the backend handles game logic and AI computations, ensuring secure cross-origin requests for frontend-backend communication. Flask’s lightweight framework enables quick data processing, while Flask-CORS manages secure requests between client and server.
  • Frontend-Backend Communication: Data exchange between the frontend and backend is handled asynchronously via fetch requests, enabling real-time communication. The use of asynchronous JavaScript and WebSockets ensures seamless data flow, allowing immediate user feedback on moves and updates from the AI.
  • API Design and Endpoints: A set of RESTful API endpoints facilitates structured communication between the frontend and backend.
    • POST /user_move: Fetch available moves for the user on the current turn.
    • POST /apply_user_move: Apply the user’s selected move and update the board state.
    • POST /ai_move: Fetch and apply the AI’s optimal move based on the current board state.
