Bad Piggies is a puzzle video game developed by Rovio Entertainment, and was its first spin-off to Angry Birds. The game launched on Android, iOS, Windows and Mac on September 27, 2012. Unlike the Angry Birds games, the player controls the pigs in 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 October 2012, Bad Piggies was the fastest-selling game on the Apple App Store, and the quickest one to reach the top of the list, in just three hours. It was released for BlackBerry 10 in October 2013 and for Windows Phone in April 2014.
The objective of the game is to build a contraption that transports the pig from a starting point to the finish line, usually indicated by a map. Such contraptions are made of wood and iron (similar to Angry Birds), as well as other objects such as wheels, two-liter bottles, umbrellas (to increase air resistance), motors, fans, TNT, balloons, ropes, and rockets.
Similar to Angry Birds, the player can earn up to three stars per level, but stars are not earned by scoring points. Instead, players automatically earn one star for completing the level. For each level, the other two stars can be obtained by:
Completing the level within a certain time limit (e.g. 10 seconds)
Collecting 1 or 2 “star boxes” on the playing field
Not using a certain part (e.g. a wheel, an umbrella, etc.)
Not damaging the contraption
Transporting the King Pig along with the Freckled Pig
Transporting the Egg (this is mandatory in Flight in the Night)
Transporting the Halloween Candy (this is mandatory in Tusk ’til Dawn)
For example, on level 1-1, a player can earn three stars by completing the level, collecting a star on the playing field and by not damaging the vehicle. On some levels, it is impossible to earn all three stars at once, so the player must play the level two or more times in order to obtain three stars. Additionally, “skulls” are placed throughout the levels, in which a player can unlock the skull level in the Sandbox by finding at least 10 out of the over 40 hidden skulls.
After the release of the remaining 30 levels of Rise and Swine, Rovio added a “Feed the King” mini-game, in order to earn power-ups in the game. Whenever the player obtains a dessert during gameplay, which they can use to feed King Pig to receive power-ups such as sticky glue (makes your contraption more durable), motor boost, golden engineer, and super magnet. The King Pig only has a slight chance of giving a power-up. The only other way to get power-ups is by purchasing them in their store.
