For the third week in row, Playdom’s City of Wonder leads our AppData list of fastest-growing Facebook games by monthly active users. But on our sister site Inside Facebook, it’s edged out by a CrowdStar app, Quiz Planet, while multiple CrowdStar games are suddenly racking up big gains.

Happy Pets and Happy Aquarium are the two games that CrowdStar put on the list, with over a million new MAU combined. However, those two don’t give the whole picture. At time of writing, we’re watching CrowdStar’s two brand-new titles, It Girl and Pop Boom, fly up the charts with over half a million new players each.

We reviewed the two titles late last week (here and here), and found them to be both good and original. It’s too early for quality to be driving much player growth, though. CrowdStar has likely pulled out the stops to try to achieve new growth.

Skipping to number six, Madden NFL Superstars is on its way up, although so far it’s growing no faster than EA SPORTS FIFA Superstars did in its early days.

The Price Is Right Game is still doing its part to convince developers that kitschy game shows are a great idea on Facebook; the question at this point is, who will get rights to Jeopardy?

Finally, Digital Chocolate is keeping the pace with MMA Pro Fighter and Millionaire City running neck-and-neck; most of the remaining apps on the list picked up fewer than a quarter of a million new users.
