A stake in social gaming monolith Bigpoint has changed hands in a deal said to value at $350 million, reports Develop, saying: "The transaction is complex and not all information has been disclosed." Here's word on the deal, which still needs to gain regulatory approval:

In June 2008, General Electric, NBC Universal and private equity firm GMT Communications acquired a 70 per cent controlling share of Bigpoint. That deal was valued at about $100 million.

Now two other private equity firms have acquired a controlling stake from that 70 per cent.

TA Associates and Summit Partners LP – both based in Boston Massachusetts – have obtained a “slight majority” of the company.
