Google continued its acquisition spree this week by purchasing app developer Jambool.

Jambool has been around since 2006, but in 2008, it launched Social Gold, a platform intended to help developers monetize their virtual currencies.

"Our vision is to build world-class products that help developers manage and monetize their virtual economies across the globe," Jambool founders Vikas Gupta and Reza Hussein wrote in a blog post. "When the opportunity arose to join forces with Google to execute against this vision, we couldn't pass it up."

Google will "bring the Social Gold platform to Google's global users," they wrote.

The duo did not have many details about what's in store for their company, but said they "aim to deliver the most frictionless, seamless transaction experience inside applications and games on every platform."

In the first half of 2010, Social Gold processed more than double the payment volume it processed in all of 2009, Gupta and Hussein said. The company has also opened its platform to hundreds of developers.

"The fact that our highest revenue day was in the last week attests to the continued growth of online gaming," they said.

Last month, it was reported that Google invested $100 million in online gaming giant Zynga, creator of FarmVille and Mafia Wars. This, according to TechCrunch, is part of a planned Google Games platform. Several weeks later, The Wall Street Journal said that Google is in talks with a number of game producers, including Playdom, Electronic Arts, and Zynga regarding the new service. Google has not confirmed these plans.
