That's just one of many impressive stats CEO Mark Pincus shared in his presentation at Web 2.0 Summit in San Francisco today.
Pincus also said a mind-boggling 320 million people have played a Zynga game. And at any given time during the day, at least four of your friends are playing, says Pincus. The latter stat goes hand-in-hand with what Pincus refers to as the company's "dog activated" strategy, meaning users know that when they see the Zynga dog, their friends are there.
Here's another unique stat indicative of extreme gameplay on the platform: Users of Zynga's FrontierVille game have created 650,000 same-sex marriages.
Pincus also shared that the company has 10 major games being produced by 13 studios in six different countries. Plus, Zynga has made six acquisitions in as many months and now has 400 people working on new games slated for future release.
