Though last month displayed growth for the top Facebook applications, February appears to be singing a different tune. This time around, 16 of the top 25 Facebook games have experienced loses. Of those, however, half still managed to keep the monthly active user decline under 1 million players.

Despite the negatives, a number of newer games have shown significant growth. As one might expect, CityVille continues its tremendous incline (at least for the month, as it’s fallen in recent weeks) but the top 25 also shows a bit of staying power with its “girls-only” titles. Both It Girl and Mall World continue on their upward trends for the second month in a row, with the former gaining over 1.2 million users. This month also has two newcomers and a returning app to the list in the form of Boyaa’s 德州撲克(中文版) or Texas Hold’em (Chinese Version), LOLapps’ Ravenwood Fair, and wooga’s Bubble Island.

It’s also important to note that the trends for the largest apps are not the same as the trends for smaller apps. In a detailed article last week, we examined data showing that dozens of smaller social games have had a great 2010.

Here are the highlights for the Top 25 Facebook Games for February 2011:

• As noted, Zynga remains on top with the astounding growth of CityVille, having gained over 18.4 million MAU for a total of over 98 million.
• Other Zynga games, however, drop dramatically, with most loosing well over one million MAU. The only two to grow is the classic Texas HoldEm Poker (#3), who gains 1.9 million users, and YoVille (#21), who gains a bit over 200,000.
• Digital Chocolate’s popular Millionaire City has also slowed in its growth, having lost approximately 400,000 MAU.
• It Girl, from CrowdStar, moves up significantly this month, changing from #18 to #13. It’s MAU totals out at just shy of 8.1 million.
• Car Town also grows, moving up from #17 to #14 as the Cie Games title gains around 741,000 new users.
• A newcomer to the list, Chinese app 德州撲克(中文版) from Boyaa makes its appearance at #15 with 7,756,670 MAU.
• LOLapps makes its first appearance on the top 25 this month with their popular title Ravenwood Fair. Having gained nearly 2.3 million MAU, the title caps out at just over 7.2 million.
• Playdom’s City of Wonder sees a significant drop (#13 to #23) as the city-builder declines by nearly 2.3 million MAU.
• Making a reappearance on the list at #25 is wooga with its simple puzzle app, Bubble Island. The game racks in an MAU count of approximately 5.9 million.
