Inside Facebook

You could say Playfish is on a roll. The company’s fourth title, Pet Society, has landed at #12 on the latest Inside Social Games Top 25 Facebook Games charts in its first month after release. Pet Society nearly joins the company’s three other titles in the Facebook Games Top 10.

Meanwhile, Lil Green Patch, Texas HoldEm, Owned!, and Friends For Sale continue to sit atop the charts. Holding strong are Zynga and SGN, with SGN’s newly acquired (fluff)Friends hanging tough at #22 and Zynga’s newly acquired YoVille showing staying power at #10.
