Amazon’s GameCircle, the company’s answer to Apple’s Game Center, is receiving a major upgrade that includes the expansion of GameCircle to all Android devices. The service, which at launch had only supported Kindle Fire, already provides support for syncing progress, achievements and leaderboard data between devices, but Monday’s upgrade will also now include conflict resolution. This feature arrives as an improvement to Amazon’s Whispersync technology, which now offers a more simplified interface for quicker integration, and allows for queuing updates to support offline operation. As the company explains in a blog post announcing these changes, these updates mean that customers’ game data will automatically sync across devices, even if they temporarily play offline.
