Berlin-based Wooga, a social gaming company, has closed a round of venture funding from Holtzbrinck Ventures.
Wooga makes Brain Buddies, a popular Facebook game similar to another game called “Who Has the Biggest Brain?” by Playfish, one of the biggest Facebook app developers.
According to Softpedia, the game has reached 2.5 million users a little over a month after it was launched, and is still growing at an average rate of 100,000 users per day.
