Real-Time and Turn-Based Multiplayer Support

Felgo Multiplayer supports both real-time and turn-based gameplay, so you can use it to make many different types of multiplayer games. It's perfect for making player-vs-player games like 'Words with Friends' or games for a large amount of players, such as 'Clash of Clans'.

With Felgo Multiplayer, you can now rival these games and make whatever kind of multiplayer game you like.

Matchmaking and ELO Rating System

Felgo Multiplayer includes a matchmaking feature that allows you to play with your friends or join already running games. It also includes an ELO Rating System that matches players against opponents of a similar skill level to ensure competitive gameplay.

Friend System and Social Features

Felgo Multiplayer lets you add your friends or make new friends with players you meet in-game. You can also compare your highscore with your friend’s in a dedicated Friends leaderboard.

These leaderboards are sure to increase your retention and engagement rates as players compete against friends and international players to reach the top of the rankings.

Interactive Chat & Push Notification

Felgo Multiplayer features a messaging system so you can chat with your friends, even if they’re not online. This makes it easy to discuss games or arrange future matches. Best of all, Felgo Multiplayer sends Push Notifications to players when they receive new messages or game invites.

In-Game Chat

Felgo Multiplayer allows players to communicate during gameplay with an in-game chat feature. Players can use it to discuss game results with one another, message their friends or chat about the latest news with people from all over the world, right in a running game.

This feature adds a strong social element to any multiplayer game and creates an engaging experience for young and old players alike.

Example Implementation

This is an example of a minimum QML implementation of a turn-based multiplayer game. It features the default matchmaking UI and players take turns in clicking one button.


The default matchmaking UI allows you to create games, join games and even invite other players and friends.

Turn-Based Gameplay

Only one player is active at a time. The server is notifying each player when it's their turn.
