Most active Facebook games over the past 4 weeks

(All rights reserved - Zynga)

A Facebook game currently needs just over 6 million regular users to break into the top 20 most active Facebook games. FarmVille rule the roost and will do for a long time to come, with a gap of over 40 million players separating it from nearest competitor and fellow Zynga stablemate Café World. Zynga are responsible for 7 of the top 10 games.

Most of these games have experiences no growth or even a slight drop-off in usage since half-way through December, apart from Happy Island, Happy Aquarium, and Texas HoldEm Poker which continue to pull in fresh players.

Roller Coaster Kingdom appears to be in free fall, shedding 6 million theme park managers in the last month, and even hot new game PetVille has tailed off since the New Year. How long can those resolutions last?
