[Every other week, we examine 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.]
The most popular title on Facebook, Zynga's Farmville, shrunk by 800,000 monthly users in the past two weeks, but at a total of 61.6 million players, it still has double the audience of the second biggest app, and that loss is much less than what it's suffered in recent weeks since the social network's app notification changes.
Texas HoldEm Poker at #2, another Zynga app (get used to seeing that developer's name in this week's tally), lost around half a million players and now has a total of 27.9 million users. Treasure Isle, also from the FarmVille studio, dropped from #3 to #5 after losing 1.1 million islanders -- its total is now at 19.2 million.
Taking Treasure Isle's spot is Zynga's FrontierVille, which has managed to climb to #3 on the chart and pick up 20.7 million gamers, almost 4 million more than its count two weeks ago, in just six weeks since its launch.
Zynga has three other titles in the top ten: Cafe World at #4, minus 243,623 patrons with a 20 million total; Mafia Wars Game at #6, less 226,066 mobsters with a 17.9 million total; and PetVille at #10, giving up 353,581 virtual pet owners with a 14 million total.
The only non-Zynga titles in the top ten are MindJolt Games at #7, losing 933,681 players for a 17.6 million total; Electronic Arts' Pet Society, less 192,318 users for a 14.1 million total; and RockYou's non-game Birthday Cards at #10, which parted with more than 2 million celebrators for a 14 million total.
