Bad Piggies is a puzzle video game developed by Finnish video game developer Rovio Entertainment, a spin-off to
Angry Birds. The game launched on iOS, Android, Windows and Mac
on 27 September 2012. Windows Phone and Windows 8 versions are
scheduled to follow later. Unlike previous games in the series, in this
entry the player controls the pigs, building devices that travel on land
and air to find pieces of a map to find and take away the Angry Birds' eggs. As of 7 October 2012,
Bad Piggies is the fastest-selling game on the app store, and the quickest one to reach the top of the list, in just after three hours.
