Amazon introduced Whispersync for Games last year alongside its updated Kindle Fire hardware, promising game syncing and leaderboards that worked across multiple Kindle Fire devices. However, standard Android devices were left out, until now — a post on Amazon's mobile developer blog indicates that the GameCircle technology that powers Whispersync for Games can now be built into any game, not just ones built specifically for the Kindle Fire. We're not sure how many developers will choose to work with the more limited Amazon-only solution instead of Google's recently-announced Play game services, but it's yet another option to help people get more from their mobile games. Of course, the service could also be a selling point against Google's solution as well as Apple's Game Center if Amazon ever rolls out its long-rumored Kindle smartphone.
Update: This story originally stated that Whispersync for Games would only work on apps from the Amazon app store. Amazon has since let us know that GameCircle and Whispersync for Games can be incorporated into apps on both Amazon's own store as well as games in the Google Play store.
