Facebook has compiled a list of its most popular games for 2011, as well as lists of other games with notable achievements for the year.

The data was compiled primarily using active user counts and user reviews. Facebook adjusted its methods for counting active users in October, which may have had an impact on the final figures used to compile its lists. Facebook also tells us that, of its monthly gamers, 25% play at least ever other day with the average gamer playing more than three different titles per month.

Here’s the list of Facebook’s top 10 most popular:
