Zynga’s FarmVille 2 has been dominating the charts since it launched in October, but it looks like February 2013 is going to be the month known for the game losing its top spot among Facebook apps, both by daily and monthly active users.

During this time frame, FarmVille 2 managed to be the No. 1 spot by DAU (until this month, when it was surpassed by Candy Crush Saga) and was still holding the No. 1 spot by MAU at the time of Zynga’s earnings report last week. Looking at our traffic-tracking service AppData reveals this is no longer the case, as CoasterVille is now the No. 1 app by MAU on Facebook. While we can no longer get an exact user number under Facebook’s revised ranking system, both CoasterVille and FarmVille 2 still have far more than 10 million MAU.

Interestingly, the game’s performance by DAU doesn’t mirror the MAU increase. While CoasterVille still sits in the 1 million DAU tier, it’s apparently dropped 11 spots over the past week. As a result, it now ranks lower than longstanding apps like Social Point’s Dragon City, Wooga’s Diamond Dash and King.com’s Bubble Witch Saga. FarmVille 2, meanwhile, is continuing to perform strongly in terms of DAU, but it has yet to retake the No. 1 spot from King.com’s Candy Crush Saga.
