Building a multiplayer Tic Tac Toe game over a network requires handling real-time communication, synchronizing game states between multiple clients, and ensuring smooth user interaction. Key challenges included designing a robust client-server architecture, managing socket connections, and preventing conflicts when multiple players make moves simultaneously.

A Java-based client-server model was implemented using sockets. The server manages game logic and player turns, while clients connect to the server to send and receive updates. Both GUI and terminal interfaces were supported, allowing real-time multiplayer gameplay. Proper synchronization and error handling were added to ensure consistent game state and a smooth user experience.
