In an attempt to follow-up the overwhelming success of Angry Birds, Rovio has released Bad Piggies, which is now available on Android and iOS devices. Focusing on the egg-thieving pigs, the new game relies the pigs' engineering and building skills to create devices and contraptions needed to reach specific goals. Bad Piggies shares some elements with Rovio's second but less successful game Amazing Alex. While it doesn't offer the instant gratification of Angry Birds, it does require other parts of your brain to work and is fun in the puzzle sense.
