Every other week, Gamasutra examines the most popular Facebook games according to monthly active users, looking at the top titles and developers on the social network to see who's attracting or losing players. After several weeks of rapid audience growth, Zynga's FarmVille 2 is the most popular game on Facebook with nearly 62 million monthly active users. The original FarmVille is doing pretty well, too -- it's the eighth most popular game and has 17 million players. But FarmVille 2's popularity is such that it has nearly double the user count of its closest competitor, Texas HoldEm Poker/Zynga Poker, which has 33 million players. The card game's numbers had been stable for some time now -- unusual for Zynga titles at the top of Facebook's games leaderboard -- but it's lost 6.3 million users in the last month. In fact, while FarmVille 2 is doing pretty great, the audiences for all of Zynga's other titles are shrinking. Bubble Safari has lost 4.3 million users in the last four weeks, ChefVille 14.9 million, Zynga Slingo 14.4 million, and The Ville 8.2 million. Those declines have allowed non-Zynga titles to rise up on the leaderboards. Wooga's Diamond Dash, for example, is now at #6 with 19.8 million players, even though it's shed 700,000 users. And King.com's puzzlers, Bubble Witch Saga and Candy Crush Saga, have also jumped up to the #7 and #9 spots respectively, despite both losing a considerable amount of players in the last month. You can see the full list of the top 20 Facebook games below:
