In 2014, King purchased Defold, and in 2015 plans previously made were put into motion to release Defold as a fully free game engine. Their goals with doing this were first to improve Defold by sharing it with a community, second to show the world the technology, and third to be able to hire more developers already familiar with the technology. King uses Defold as one of their three internal game engines (one other major one is for their private use only and is called “Fiction Factory” an older, more 3d focused, C++ cross platform engine (iOS, Android, HTML5, PC, OS X) which powers Candy Crush, Pet Rescue, Farm Heroes, Bubble Witch Saga, and more), and has produced the hit game Blossom Blast Saga with it. The Defold engine team remains separate from the King game or other engine teams. Currently the Defold development team is about ~12 people according to King jobs listings.
