As promised a few weeks ago, Rovio has launched the Facebook-connected variant of its Angry Birds game, Angry Birds Friends, for iOS devices.
The gameplay is essentially the same as in regular Angry Birds games. The main difference is that in Friends, you can compete against your Facebook friends. The game features tournaments with new levels every week, daily rewards, gifts and challenges.
Most importantly, it automatically syncs with your game on Facebook, so you don't have to start that extra-tough level all over again when you're removed from the computer.
The game is compatible with the iPhone 3GS or later, iPod touch third generation or later and iPad.
You can get the free, ad-supported version of Angry Birds Friends here. Tell us how you like the game in the comments.
