Social gaming giant Zynga is reportedly zooming in on a long-awaited switch to real-money gambling, according to a recent report from eGaming Review.

The company, which runs the biggest social poker game on Facebook, has according to the report called for bidders to submit their pitches for a real-money gambling platform.

Zynga has for years nurtured its reputation as a leading free-to-play games developer and provider, but the company has openly been exploring its possibilities for entering the real-money gaming market since the beginning of 2012.

So far, major platform providers like GTECH2, Playtech, and others have shown interest in working with Zynga, in what could be a new power-house partnership.

Additionally, Zynga has also been reported to be one of altogether six companies who are eyeing a takeover of bwin.party's Ongame Network.

The company has also been observed as it has begun detaching itself increasingly from Facebook in recent months, most notably by launching its own stand-alone gaming platform at Zynga.com.

It is likely that a full-scale switch to real-money gaming would be come to this independent platform, while the free-to-play platform continues to operate as part of the very lucrative partnership with Facebook.

Zynga Poker was this week listed by Pokerscout as the world's leading play money website with almost 120,000 active players during peak hours - almost five times as many as the world's biggest real-money site PokerStars.com.
