25 hottest games on Facebook in 2012

Games can be both a welcome and an annoying diversion on Facebook, the world's most popular online social network. This year, Facebookcrossed a big milestone - reaching 1 billion active users. Game companies such as "FarmVille" creator Zynga and Rovio Entertainment of "Angry Birds" fame seek to tap into that vast base of users to gain more players for their games. 

This week, Facebook issued a list of the 25 top-rated games that launched on Facebook in 2012. The company says the rankings are based on user ratings and engagement with the games. It's the same methodology that Facebook uses to rank apps in its App Center. 
Some of the games are played on Facebook's website, while others are only on Apple's iOS or Google's Android devices using Facebook's app.
