Zynga has announced that more than 100 million unique users now play its social games monthly, “making it the largest online game destination”.

The company says that it has 200 million active monthly users across all its titles, which include FarmVille, Mafia Wars and FishVille, with one million users purchasing virtual goods each month.

Launched in September, Zynga’s Café World has surpassed nine million daily active users, while FishVille, released this month, has surpassed six million.

FarmVille is the company’s largest game with a player base of over 65 million, 26 million of whom play daily. Zynga has just launched FarmVille.com, a new web site that uses Facebook Connect integration to bring the game to a standalone portal.

“Our games continue to delight and connect players as they immerse themselves in their worlds of farming, fishing or running a restaurant,” said Mark Pincus, CEO and founder of Zynga. “With the popularity of virtual goods today, we are in the early stages of a new economy that could grow and shape the future of the web.”

Zynga also says that direct user purchases account for approximately 90 per cent of its revenues. A lawsuit recently launched against Zynga and Facebook over the deployment of offer-based advertising alleges that the social gaming firm makes one third of its revenues from commercial offers such as CPA advertising.
