Moblyng, a developer of games using HTML5 for mobile devices, is looking to raise about $10.9 million and has raised about $7.5 million of that so far, according to a recent filing with the Securities and Exchange Commission.

Moblyng began life as FlipTrack in 2007, when it ported Flash slide shows to mobile operating systems. It then changed direction to help developers of mobile games quickly port them to other mobile operating systems.

The company’s site now indicates that it is looking to become the top developer of HTML5 games on social networking sites and mobile devices. HTML5 is seen as a large competitor for Flash, which most casual games are built on. Most websites that host videos also use Flash to play them. But Flash is lacking on some mobile devices — most notably the iPhone and iPad — while HTML5 is available in most mobile browsers.

The Redwood City, Calif.-based company teamed up with casual game developer Playdom earlier this year to publish Playdom games such as Mobsters and Sorority Life on mobile platforms such as the WebOS, Symbian, BlackBerry and Android. Moblyng has also teamed up with social game maker LOLapps, which makes lighthearted apps such as Roses for You on Facebook.

Moblyng also publishes its own games and is a top game publisher on the Android Marketplace. It made games like Dungeon Quest, M:Mafia and M:Racing. It also charges development fees when it co-publishes partner titles and gets a percentage of that revenue. Moblyng has had more than 5 million downloads of its games in the past year.

Moblyng has raised $10.65 million before this recent fundraising round. Moblyng is funded by Mohr Davidow Ventures and Deep Fork Capital. The company also received another $500,000 from unnamed angels.
