In this post I want to give you a brief insight into Google Play Game Services (GPGS). GPGS was announced on the Google I/O 2013. It consists of different services, which provide features like leaderboards, real-time multiplayer, achievements and cloud save for cross-platform games. The APIs are available for Android, iOS and Web through the Play Games services SDK. Some features require an authentication of the player, which is done via G+ login. To us this service a new game must be created in the Google Play Developer Console so that the supported platforms with their credentials could be added.
