Because so many people liked this game, Rovio Mobile released special editions of "Angry Birds" called "Angry Birds Seasons", "Angry Birds Rio" and "Angry Birds Magic". The special versions are basically the same game with some differences. In "Angry Birds Seasons" there are levels inspired by holidays or seasons. "Angry Birds Rio" is set in Rio de Janeiro and instead of pigs and wingless birds there are monkeys and birds from the movie "Rio". "Angry Birds Magic" is just a special edition for Nokia and for more levels you have to use NFC.
