Miniclip has announced the acquisition of Supersonic Software and its publishing subsidiary, Appynation. The terms of the acquisition were not disclosed. Supersonic will be Miniclip's fourth UK studio, based in Leamington Spa. Supersonic Software was founded in 1988 and worked on franchises such as Micro Machines. It has been focusing exclusively on mobile games since the 2010s and is known for titles such as One Clue Crossword and Picture Cross. The studio was a founding investor in mobile publisher Appynation, and it later bought the remaining shares in the company, making it a wholly owned subsidiary. Co-founder Andy Williamson said he's confident Miniclip will "respect [Supersonic's] culture and indeed enhance it."
