Naughty piggies has nothing to do so they started building strange vehicles.
Bad Piggies is very interesting mix of logic and platformer gaming where you see the map in the beginning of every level. The goal is getting a pig in the end of every level using various parts and creations. You have always limited number of pieces and tools. Use boxes, wheels, fans, flying thingies. Some of the can be turned on or off so you can decide when to use them.
