Rovio has recently released a free edition of Angry Birds for both the iPhone and iPad, complete with 12 brand new levels with full Game Center functionality. This version is ad supported, so you may experience annoying video or text pop-ups, but hey, it’s free. If you already own the full game, this version is still a worthwhile download just for the handful of new levels.
The full version of Angry Birds on Android uses the same ad supported model, so Rovio could be planning on fleshing out this free iOS version into a full game, as an alternative option for users who can’t spare $.99.
Angry Birds HD Free features challenging physics-based demolition gameplay, and lots of replay value. The 12 levels, set in 4 mini episodes, have been created specifically for Angry Birds HD Free. Each of the levels requires logic, skill, and brute force to crush the enemy.
