Leading mobile games company, Playtika, announced that it has completed its acquisition of Austria-based developer Supertreat. Financial terms were not disclosed. The announcement comes just a few weeks after the company acquired German puzzle and hidden object specialist, Wooga, and a little more than a year after it acquired Jelly Button Games, both significant steps in the company's strategy to further expand into casual games. As part of the acquisition, Playtika will add the successful "Solitaire Grand Harvest" app to its growing portfolio of casual game titles. "Solitaire is one of the most evergreen single-player games and a very competitive category, but Supertreat cracked it and succeeded in creating one of the highest grossing solitaire games within just a year of its launch," Nir Korczak, Playtika Chief Marketing Officer.
