Andrograde is a new Flash game portal and monetization service that just launched late last year. Founded by William Perone (formerly an early employee at social mobile service Loopt), the consumer side of the service is a casual/social site with a collection of Flash games, and developers can submit their games to be added to the library. Most of the games on the site today are simple and easy to learn.

Andrograde offers basic social features as well, including a live chat system integrated into all the game pages. Many titles also have leaderboards for user generated content, like levels.

However, the core of the service is its virtual goods platform. Developers offer their game for free to Andrograde and create features in their game that costs “Andrograde Points” (which can be used in any game containing the Andrograde API). Every time a player purchases something in your game, you get paid for it at the end of each month.  Developers are responsible for making the bonus features seem compelling enough to merit a purchase.

Andrograde says it offers developers an average $1 for ever 550 plays, and claims better performance than services like Kongregate, Game Jacket, and MochiAds offer.  Developers can check out an API demo game here.
