Zynga confirms four mobile game studio acquisitions in late 2011

We knew that Zynga bought four companies in Q3 2011, but today the company reveals to Reuters the names of four companies it acquired throughout the end of 2011: GameDoctors, Page44 Studios, HipLogic and AstroApe.

German developer GameDoctors appeared on our radar late last week as its older game, Zombie Smash, suddenly reappeared in the App Store rankings. We also heard about the AstroApe acquisition back in August 2011 when the developer’s top employees all updated their LinkedIn profiles with Zynga positions.

Page44 Studios — acquired in September, according to Zynga’s head of mobile, David Ko — is a bit of a surprise as the San Francisco-based developer is only really known as collaborating with indie darling 2D Boy on hit downloadable game, World of Goo. Zynga also acquired San Francisco-based developer HipLogic around the same time; that developer is best known for its mobile UI platform services.

Ko didn’t provide Reuters with any additional details on Zynga’s mobile strategy. Its latest mobile title is Scramble With Friends, released this month.
