Amazon has just announced GameCircle, a new set of APIs for Kindle Fire game developers. GameCircle's offerings include an achievements feature, so you can keep track of the badges and awards you collect within a game, and a leaderboard system for competing against other gamers.

And if the rumors are true that an Amazon smartphone is on the way, it's easy to see why the company is making sure developers have the option to build seamless cross-device game experiences.
