Bad Piggies Free

The free version of Bad Piggies was released on December 12th, 2012 (the day after Angry Birds Star Wars Free was released). It features 30 levels, 12 levels in Ground Hog Day, and 4 others in other episodes. The Field of Dreams sandbox could also be purchased, with an upgrade to unlock all the levels added at a later date. In 2016, the game was updated to include all of the levels for free, but most of them can be unlocked by watching in-game ads.



Discontinuation
The app was discontinued following the addition of the Cake Race into the game.
