Wooga Hits 20M Users, Now Fourth Biggest Facebook Game Dev

German social game maker Wooga (Bubble Island, Monster World) now has 20 million monthly users on Facebook, and is the fourth biggest game developer on the social network in terms of monthly audience size. Wooga entered the social game space 20 months ago, and has expanded its total userbase to overtake Facebook developers like Digital Chocolate, PopCap, and RockYou in recent months. The company's userbase is now larger than that of Playdom, the developer purchased by Disney last year for as much as $763 million. Playdom's monthly user count has plunged from around under 20 million users to 17.8 million in the last couple of weeks. Most of Wooga's recent growth, meanwhile, has been driven by the newly released gem puzzler Diamond Dash, which picked up almost 3 million players just in the past month. According to AppData figures, Wooga's audience numbers are still behind Zynga's (268.7 million users), Electronic Arts/Playfish (36.1 million users), and CrowdStar (27.8 million users), but the ambitious developer says it is "striving to become the second largest developer of social games on Facebook by the end this year." "Capturing 20 million active users in just 20 months and surpassing Playdom to become number four in the world is a stunning accomplishment," says Jens Begemann, founder and CEO of Berlin-based Wooga, which has around 70 employees. Begemann continues, "We will remain focused on producing high quality games with a unique game experience for the future. With our ambitious team, we aim to become number two by the end of this year."
