Inside Facebook

Top social game developer Playfish announced today that it has raised a $17 million round of financing from Accel Partners and Index Ventures. Along with Zynga and SGN, Playfish becomes the third social game developer to have raised over $20 million for the creation of a new wave of social games.

Playfish will use the money to build out its game studios around the world.  It already has offices in San Francisco, Beijing, and Norway.

As we noted last week, Playfish sports 4 of the top 10 applications on Facebook. Collectively, the company has over 10 million monthly active users on Facebook alone, though it will be moving onto other platforms soon. Playfish released its first games on MySpace in recent weeks.
