Social gaming company RockYou has acquired Ryzing,a developer of the game Bingo by Ryzing. That title has been available since 2010, but RockYou took over as publisher earlier this year.

The Ryzing team has six members, including chief executive Manu Gambhir. The game has more than 75,000 daily active users and it has a unique twist on Bingo that gets around restrictions on cash payouts by awarding users prizes via a sweepstakes method. The company has developed a real-money, proprietary gaming platform. If online gambling is legalized, it would be a simple matter for the Bingo game to be converted to real-money gambling, Gambhir told us earlier this year.

Terms of the deal were not released.

RockYou also said that it plans to move its main headquarters from Redwood City, Calif. to the Potrero Hill district of San Francisco on June 18.
