Initially released for the iOS operating system ( iPhone and iPad ), then on Android, Symbian, Windows PC / Phone and even Mac OS, the popular Angry Birds game is now available on Facebook too, where you can access it just like you access a regular application.
Precisely, we are talking about the Beta version of the Angry Birds game, and major differences compared to the rest of the platforms are Facebook exclusive levels and the right column, which was redesigned for sharing on Facebook. You can invite your friends to play and you can also compare your points with other Angry Birds players.
The game starts in a regular Facebook window and can be played in full screen too.
The biggest problem right now is optimization. Angry Birds for Facebook does not run smoothly and the graphics needs improvement as the developers have not implemented anti-aliasing optimization,but hopefully this will be fixed in the future.
