CrowdStar‘s Top Girl mobile game is one of the top-grossing titles on Apple’s iOS platform. Now it is moving over to Google’s Android platform and will debut exclusively on the Amazon App Store. That means it will be available on the new Amazon Kindle Fire tablet, which features a 7-inch touch screen.

CrowdStar said Top Girl will be sold exclusively on the Amazon App Store for two weeks after the launch. The title is the first major mobile hit from Burlingame, Calif.-based CrowdStar, which is making a big push in mobile as part of a strategy it calls Project Trident. With that plan, CrowdStar aims to be a big play on mobile and Facebook as well as expand into foreign markets.

“CrowdStar is entirely focused on Project Trident this year and Top Girl’s Android launch is representative of that,” said Blair Hamilton, head of studios at CrowdStar. “Now our ‘Girl’ social gaming franchise is thriving on Facebook, iOS, and Android.”

Top Girl was released on iOS in May and surpassed 10 million downloads after 10 days. Three days after launching, it became the top-grossing game in the App Store, beating out Angry Birds and Zynga Poker. In the game, players create their own characters and engage in virtual shopping. They create fashionable avatars who can climb the fashion social ladder, collecting money by doing modeling jobs, buying new outfits, and going to popular clubs. The game also has a dating feature, where users can flirt and snag a boyfriend who will give them gifts.
