Multiplayer TicTacToe Game using Flutter, Socket and MongoDB

Build a multiplayer Tic Tac Toe game with Flutter, Socket.IO and MongoDB. This project connects the game interface with a Node.js/Express server, showing how rooms, player state and game events work together across clients.

Connect players through a shared game room

The Flutter setup covers a main menu, responsive layout, named routes and reusable widgets. The server sequence introduces Express, MongoDB Atlas and Socket.IO before creating and joining rooms. Provider and player models then connect room events with the client interface.

• Create the menu and room-creation/joining interfaces.
• Connect Socket.IO clients with server events.
• Model rooms and players and manage their state.
• Build a waiting lobby, scoreboard and game board.
• Track turns, check a winner and implement play-again and end-game behavior.

The course expects basic Dart and Flutter plus introductory Node.js and MongoDB knowledge. It suits learners ready for a project involving more than one running client. A compatible Flutter development setup and separate backend/database access are needed to follow along. Work through the event flow carefully, testing how each player’s action changes the shared game state.

PLR allows you to adapt, rebrand and resell this multiplayer-game training. Its room and event-based structure can support a Flutter project catalog or a practical introduction to real-time client/server applications.
