Games like geo challenge

Playfish, currently a property of Electronic Arts, was a developer of free-to-play social network games. Playfish was founded in 2007 by Kristian Segerstråle, Sebastien de Halleux, Sami Lababidi and Shukri Shammas. It closed in 2013. Playfish in the past had attracted up to 55 million users a month, with over 37 million users coming from Facebook users. In October 2008, they secured US$17 million in venture capital funding from Accel Partners and Index Ventures.

Who has the Biggest Brain? was the company's first release. It was one of the first Facebook games to attract millions of daily players, and allowed the company to raise the funding necessary to produce other games. The company made money by selling virtual goods inside its games.
