The London-based firm said Tuesday the funds will help boost its chances to become a leading developer of games for connected social gaming networks.
Playfish's titles include Who Has the Biggest Brain, Pet Society, Geo Challenge, Bowling Buddies and Word Challenge.
"Four of our five games are now on Facebook's top-10 games list," said Playfish CEO Kristian Segerstrale.
Playfish claims to have over 10 million monthly active users. The company also has offices in San Francisco, Beijing and Troms.
"Our games are designed around social emotions--people play our games with the same people that they would play cards, play board games or go bowling with in the real world," Segerstrale added.
