Zynga buys more studios in silence

Social games kingpin Zynga has added two more studios to its global fleet, but the company hasn’t revealed who it has bought.

In an updated financial filing, the San Francisco headquartered group said it has “acquired two companies to grow our online social game offerings and our software development and engineering teams”.

It said the buyouts, totalling $4.9 million, was made between October 1st to November 17th.

Zynga had embarked on an unparalleled acquisition spree in the first nine months of 2011, having acquired thirteen studios in that time frame. The Farmville creator spent more than $40 million on these new additions.

Total employee headcount has passed 2,500, according to CEO Mark Pincus.

Zynga is thought to be edging ever closer to its IPO, which is speculated will occur just after the Thanksgiving holiday. The firm had hoped to go public several months ago, but wider market turmoil has hindered progress.
