Localized-Connect 4

This project is a TCP-based multiplayer version of the classic Connect 4 game, written in Go. It allows players to connect and play over a network in various game modes. The server handles communication between players, broadcasting moves, and determining game outcomes.

Features

• Multi-Player Support: Supports multiple game modes including:
  • Server vs. Client
  • Client vs. Client
  • Server vs. Computer
  • Client vs. Computer
• Customizable Board Size: Choose between predefined sizes (8x6, 6x7, 9x14) or define a custom board size.
• Graceful Networking: The game utilizes TCP for smooth client-server communication and handles client disconnections gracefully.
• Real-time Gameplay: Players can make moves in real time, and the server broadcasts updates to all connected clients.

How to Play

Game Modes

1. Server vs. Client: The server plays against one connected client.
2. Client vs. Client: Two clients can connect and play against each other.
3. Server vs. Computer: The server plays against an AI opponent.
4. Client vs. Computer: A single client plays against an AI opponent.

You can choose from the following board sizes:

• 8x6: Standard 8 columns, 6 rows.
