With a makeover of its original hit game on iOS, Crowdstar is ending the year by pulling in 50 percent of its current revenues from mobile while the rest is coming from Facebook and abroad. (This isn’t a cumulative figure over the year. It’s revenue flow now.)

It’s a sign of the times as many of Facebook’s leading game developers have migrated toward more promising fronts on Android and iOS as growth for social games has slowed. Crowdstar, Zynga, Funzio and Booyah have probably had the most noticeable crossover success this quarter. Other Facebook stalwarts like EA Playfish, Wooga and Disney’s Playdom haven’t had as much visibility on the top-grossing charts, however.

This past week, Crowdstar retouched its iOS hit Top Girl by polishing the game’s artwork and relaunching it under the name Social Girl. Crowdstar’s changes underscore an industrywide trend toward higher production and better art, which we’ve seen in other titles like Tap Zoo 2 from Pocket Gems.

The company tweaked the game mechanics by letting players have only one boyfriend throughout the entire game. In the older game Top Girl, you could attract and then dump many boyfriends. (Yes, all of the games in Crowdstar’s Girl franchise are absurdly sexist. They’re so bad they’re practically good.)

Since its launch, the game has racked up 1 million downloads in a week, presumably mostly through the core Top Girl audience and then through other paid acquisition channels.

Crowdstar is pointing out that it’s now deriving half of its revenues through mobile, a jab at Zynga, which it says is probably earning less than 10 percent of its revenues from iOS and Android. (However, it’s worth pointing out that Zynga has six games in the U.S.’s top grossing 100 while Crowdstar has two.)

The company has made a big effort to turn its largely Facebook dependent business into one that has three prongs on mobile and in international markets.
