Google has accidentally spilled the beans on its yet to be released Google Play Games service. The idea behind Google Play Games is to allow developers to easily integrate a number of cross-platform features into Android-based games. Most of them will apparently be handled by Google's cloud.

The upcoming SDK will add features like cloud save, as well as cloud-based achievements, leadersboards and multiplayer modes. Users will also be able to transfer in-game objects, share gifts and so on.

The kicker is cross-platform support. The service will allow developers and publishers to easily integrate various cross platform features, such as multiplayer on iOS. It should give developers a bit more info on how gamers interact with their apps, thanks to a new Google Analytics interface.

The features were leaked on Google's own blog and it is believes at least some of the new feature will be officially announced at the Game Developers Conference later this week.
