Felgo Multiplayer is officially released.

Following its successful beta release, you can now access Felgo Multiplayer when you update Felgo – even as a free user. This new feature can be integrated into your game with less than 100 lines of code!

Felgo Multiplayer allows you to create real-time and turn-based multiplayer games for all supported Felgo platforms. This includes iOS, Android and Windows Phone, as well as Windows, Linux and Mac OS X. You can also enjoy an intelligent matchmaking system with ELO rating, an interactive chat feature, push notifications, cloud synchronization of player profiles & many social features.

Felgo Multiplayer has already been used to launch a successful 4-player card game, ONU, developed internally by Felgo. ONU has been available on the App Store and Google Play Store since the beginning of July and has garnered 100,000+ downloads within the first 3 weeks of its release. This is thanks to the multiplayer feature and word-of-mouth marketing. The player retention rates and engagement metrics are also way above industry standards, thanks to the multiplayer features.

The full source code for ONU, based on the popular card game UNO, is available for free in the Felgo SDK. As a developer, you can use the full source code as a best practice for multiplayer integration and create your own multiplayer games within a few days.

Real-Time & 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 with a large amount of players, such as ‘Clash of Clans’.

Many of the most successful mobile games are intended for a multiplayer audience, such as ‘Draw Something’ and ‘Hay Day’. With Felgo Multiplayer, you can now rival these games and make whatever kind of multiplayer game you like. It’s also perfect for making games like:

  • Hearthstone: Heroes of Warcraft
  • Quiz Up
  • Pokemon Go
  • NBA Jam
  • Worms 4
  • Modern Combat 4
  • Minecraft: Pocket Edition
  • Muffin Knight

Best of all, your multiplayer game will work on iOS, Android and Desktop devices using a single codebase. You can code your game once and publish it anywhere! See the new feature in action here:

Matchmaking & 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.


The matchmaking system also helps you to create games with specific opponents, like your friends. This feature is sure to boost your player engagement as players can enjoy regular gameplay with their own friends, as well as millions of players worldwide.

ELO Rating System

The ELO rating system ensures you play with opponents of a similar skill level. This is a great tool for improving your games’ retention rates. With this ELO Rating System in place, players of all levels are guaranteed challenging gameplay for as long as possible. This means you can create a game that continues to entertain weeks after a player’s first engagement.

Social Features: Friend System & Leaderboards

Felgo Multiplayer lets you add your friends or make new friends with players you meet in-game. To make playing with friends easier, you see your friends at the top of the players list when starting a new game.

You can also compare your highscore with your friend’s in a dedicated Friends leaderboard. The standard leaderboard shows players from all over the world, even on different platforms.


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.

Messaging: Interactive Chat & Push Notifications

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. Push Notifications are sent when players receive a game invite or a new friend request. This means your players can engage each other at any time, whether they’re online or not. This is a simple but effective way to boost user engagement within your game.

These Push Notifications enable you to use a ‘Late Join’ feature within the matchmaking system. When creating a new game, you can invite your offline friends and begin without waiting. They will receive a Push Notification saying “Let’s Play a Game!” while you play, and they can join you when they’re ready. Once they click the blue play button in the interactive chat, they’ll be brought straight to the game room. Players never need to wait or miss out on the fun again!

Player Profiles & Cloud Synchronization

Felgo Multiplayer lets you create your own player profile. You can upload a profile picture, set a username and decide if your national flag is displayed. It’s simple to do and no additional logins are required.

Furthermore, all player data, such as high scores or earned achievements, get synced across platforms and devices thanks to built-in cloud synchronization. This enables you to use your player profile across as many devices as you like. So you can start playing a game on your iPad and continue where you left off on your Android phone.


The player profile gives users personalization options and leads to a much improved player experience. As a community builds around your game, it allows players to stand out on leaderboards and create their own in-game identity.

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.

Chat Window

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

Cross-Platform Multiplayer Compatibility

Just like all Felgo features, Felgo Multiplayer is a cross-platform solution. Your game will work on both iOS and Android devices, but it also means players on iOS devices can play against Android users and vice versa.


Felgo Multiplayer also works on Windows Phone and Desktop platforms, including Windows, Mac OS X and Linux.

The Felgo Multiplayer component can be included in your game with less than 100 lines of code. This means you can integrate this feature into your game in less than 10 minutes. You can also use this guide to find the best video game fonts to download!
