Angry Birds Gets 15 New Levels

An Angry Birds update for iPhone and iPad just went live in the App Store, bringing 15 new levels and a new golden egg that, according to Rovio, is “as mad as a bag of hammers”.

The update, version 1.5.1, also adds compatibility for the secret code that will be given away during a Super Bowl commercial, which will let users  unlock another additional level which, once completed, will give every Angry Birds fan a chance to win a ticket to Fox’s premiere of the animated film “Rio” in Rio de Janeiro.

A special version of Rovio’s game, Angry Birds Rio, will be released in March.
