As previously announced, the Finnish game manufacturer Rovio has now released a Christmas edition of Angry Birds for Android, iPhone and iPad.

The iOS version is free for those who already bought Angry Birds Halloween, if not the game will cost you $1.99. The Android version of Angry Bird Seasons, however, is available for free from the Market.

New features include 25 days of angry birds, where you must complete a level to advance to the next, similar to an Advent calendar. In total there are 69 levels where the pigs are hiding among Christmas presents and ice blocks.

New in the iPad and iPhone version is support for Apple’s Game Center, which is a service that allows you to play against your friends over the internet and try to beat each others score. Game Center is available on every iPhone and iPad as long as they are running the latest version of iOS.
