From their site: Many APIs for gaming: (1) With the Nonoba Multiplayer API, any Flash game developer can easily create a multiplayer flash game. (2) With the Highscores API, we want to encourage competition with our simple yet powerful API for highscores and rankings. (3) Achievements API - achievements are one-time awards that you can give to players whenever they reach a milestone or achieve something difficult within your game. (4) Save the game state with our Data API and we will make sure it's always accessible for your players, even if they play from another computer.
