UK-listed online gaming operator Gaming Realms has boosted its social gaming business with the acquisition of RealNetworks’ social casino brand Slingo.

The deal will see Gaming Realms acquire the Slingo brand and patents, as well as the US and Canadian development studios of RealNetworks’ GameHouse division, plus its social and mobile publishing network.

Gaming Realms also gets the Soduko.com and Mahjong.com online domains, the entire issued share capital of social casino studio Backstage Technologies, a short-term license to the GameHouse brand and a perpetual license to the GameHouse Promotion Network.

In exchange, RealNetworks will receive a total consideration of $18m, with $10m in cash upon completion of the transaction, which expects to be done sometime in Q3. Two additional payments of $4m will be payable on the first and second anniversaries of the deal’s consummation. RealNetworks has the option of taking up to 50% of the latter two payments in Gaming Realms stock.
