Gaming Realms has signed an exclusive UK licensing deal with Seattle-based media distribution service provider RealNetworks to develop real-money gaming products using the Slingo brand.

It will use the brand to launch a real-money gaming product on its newly-launched Spin Genie offering, which is hosted on its proprietary gaming platform.

The operator explained that the Slingo brand, which through a partnership with Zynga attracted 50m monthly active users as a free-to-play game at its peak, would offer strong opportunities for cross-sell from the social casino space.

It has agreed the deal as part of its strategy to launch new gaming formats as it looks to grow its business, with the Gaming Realms board noting that such licensing agreements gives it confidence that there are “significant market opportunities ahead to achieve further progress in 2015 and beyond.”

Atul Bali, who serves as president of RealNetworks’ games division, also sits on the Gaming Realms board as a non-executive director.

First launched in 1995, Slingo combines slots and bingo mechanics, and moved into the casual gaming space through channels such as AOL, as well as becoming a popular land-based gambling title.

It then became a major hit in social casino with the launch of Zynga Slingo, though after reaching its peak of 54m monthly active users in September 2012 it declined sharply, with around 1m monthly actives left when it was removed in August last year.

Slingo was acquired by RealNetworks last year in a $15.6m deal, with a new free-to-play app, Slingo Adventure, released earlier this year.
