Today’s AppData list of the fastest-growing Facebook games by daily active users is all about City of Wonder, the new Playdom game referenced in this post’s headline. The city-building game has been leading both our monthly active user and DAU lists for a couple weeks now, and shows no sign of stopping yet.

However, the top 20 list shows a strong challenger:

Coming in right behind City of Wonder is The Price Is Right Game, by Ludia. This game is based on the classic game show of the same name; we’ll have our review for it out later this morning.

Pet Society, Ninja Saga, Sorority Life and other older games on the list seem interesting at first, but they’re not doing anything new; larger old games often produce temporary changes in their stats over the period of a few days without ultimately growing or shrinking much.

The games that are worth looking at today are MMA Pro Fighter, from Digital Chocolate, and Bubble Island and Monster World from Wooga. These two mid-sized developers are both in the process of breaking into the top 10 developers by DAU with their slow-growing hits; Digital Chocolate is at number 10, while Wooga is close behind at number 11.
