The three biggest games on Facebook are now all made by Zynga. CityVille (49 million users) is still sitting pretty at the top of the pile. CastleVille (36 million) has overtaken FarmVille (34 million) as the second most popular title.
Texas Hold Em Poker (28 million) is the fourth most popular and The Sims Social (25 million) rolls in at fifth.
The figures, released on AppData show the real extent of Zynga's continued domination on Facebook, and their impressive numbers show no sign of going down.
