Social gaming developer Plumbee says its flagship Mirrorball Slots app has exceeded the 10m download mark.

Plumbee launched Mirrorball Slots on Facebook three years ago, which was followed by the release of standalone mobile apps for iOS and Android devices. Since then, Plumbee says players have spent over 107m hours playing the app, which has generated over $50m in lifetime revenue for the company. Plumbee CEO Raf Keustermans said the stats put the title “in the upper tier of game franchises.”

Meanwhile, social casino operator GSN Games has launched its new GSN Grand Casino app. GSN says players can indulge in slots, bingo, card and table games on iPhone, iPad, iPod Touch as well as Android devices. GSN has licensed a number of familiar properties for the app’s slots offering, including Deal or No Deal and Wheel of Fortune.

GSN chief marketing officer Kevin Frisch told VentureBeat that social casino operators were “increasingly moving away from just aspiring to copy the land-based model, and are now developing experiences that can only be offered in a virtual environment.” GSN Grand Casino assigns players a “personal VIP concierge” named Heather who delivers a fully customized experience for each player.
