Bad Piggies is a physics game set in the Angry Birds universe. This time, you will be helping the pigs achieve their goals! Place the provided parts in the available slots to create contraptions that will make it possible for the pigs to collect each map piece. Some parts can be activated after the contraption has been built, allowing you to partially control the machine. Like Angry Birds, the game has a three-star system for rating your performance in each level.
