British social casino gamemaker Plumbee is launching the iOS version of its Mirrorball Slots game today.

The London-based company makes social casino games, and it has more than 300,000 daily active users on Facebook and 1 million monthly active players. But the iOS game is the company’s first move into the mobile market for social casino games, which are a hot category in the United Kingdom.

The title is a virtual currency game, where you can pay real money for virtual currency but you cannot cash out your winnings. Plumbee launched the Facebook version of the game in March 2012.

Raf Keustermans, the cofounder and chief executive officer of Plumbee, said, “It’s been a tremendous year for Plumbee, with the company achieving eight-digit revenues within its first year since launch. The move on to mobile is the natural next step for the company. We are really excited about the new iOS version. Our Facebook game continues to be a huge hit, and now with the addition of the mobile app, the sky really is the limit.”

Plumbee was founded in July 2011 and has backing from IDInvest Partners. It has a team of 50 developers. Plumbee hopes to differentiate itself from rivals with high-quality gameplay, polished graphics, and animations.
