Playfish, the social network gaming company founded by wireless industry veteran Kristian Segerstrale, announced a series B round worth a very respectable $17m from Accel Partners and Index Ventures. Playfish boasts 10m monthly users and claims that 4 of its 5 games are in Facebook’s top 10. The company also said it recently joined Google’s in-game advertising solution and presumably banks on capitalizing on this success. No word on financials but they surely are getting their slice of it (just how thick that slice is, I’d like to know). No word either on any mobile activities (which might be coming given Kristian’s background as founder of Macromedia).

Playfish’s mantra is to enable people to play games with their real-world friends via the infrastructure provided by social networks, and I can confirm that this works: I am an avid player of their games, particularly “Who has the biggest brain?” (I am no. 5 amongst my friends so far; a list which is topped by Kristian and I cannot help but think that he might possess cheat codes…).
A round of this size by investors of this pedigree raised in these times deserves our unreserved respect. You rock, guys!
