The Sims Social has over 36m monthly active players on Facebook

"Game publishing company Electronic Arts‘ newest social game, The Sims Social, has passed social gaming supergiant Zynga’s Farmville and now has 36 million monthly active users just under a month after its launch, according to AppData.
The Sims Social has held the top spot as the fastest growing application on Facebook for more than a week. The game picked up more than 1.7 million new users on Sunday, and picked up a total of about 8.3 million new users last week. It’s seen enough growth to knock off FarmVille and become the fourth most popular social game on Facebook, behind Zynga’s own Empires & Allies, Cityville and Texas HoldEm Poker. Zynga’s Farmville now has 35.7 million monthly active users."
