Amazon has enhanced its GameCircle service and released a study showing games that incorporate it monetize signficantly better than those that don’t.

GameCircle is now able to sync game data such as game play progress, achievements and leaderboards across devices using Android operating systems, not just Amazon’s Kindle line. The service works when offline, saving data for games that are compatible with GameCircle in the app on the device in use, then syncing through an internet connection to update data for access by other devices. This means a game saved during play on an Android device such as the Galaxy Tab will pick up where the player left off if they start playing on another Android device, including Amazon’s Kindles. There are currently more than 500 apps that work with GameCircle, with popular games such as Temple Run and Doodle Jump among them.

The service is modeled after Apple’s GameCenter for iOS.  It also competes with Google Play’s Game Services, although Google’s service also offers a platform for multiplayer gaming and works with iOS.

Amazon conducted a study looking at GameCircle’s engagement and monetization rates from November 2012 to January 2013. The three-month period showed games that integrated GameCircle produced 38 percent higher conversion rates and 33 percent more in-app orders than games that didn’t integrate it. When those stats are combined, Amazon says that GameCircle enabled games drive 83 percent more average revenue per user.
