This morning during Apple's iPad Mini event, Zynga employees began taking to Twitter en masse to report on significant layoffs at the troubled social gaming giant. Zynga has yet to make any official announcement and have not yet responded to our request for comment.

Individuals close to the situation are reporting that Zynga Austin bore the majority of cuts, with more than 100 jobs lost at that location. The entire Zynga Bingo and theVille teams have reported been let go, leaving only teams developing mobile products left at the office.

Gamasutra is also reporting layoffs or perhaps the closure of Zynga Boston and Zynga Chicago. TechCrunch reports that the San Francisco office is not seeing any layoffs today.

More Zynga employees have reported that an all-hands meeting has been scheduled for later this afternoon. A more solid picture of the extend and location of the layoffs is likely to follow.

Today's layoffs are the latest in a growing line of bad news for the social game maker. SuperData Research noted today that Zynga has less active players now than it had two years ago. Social game players are increasingly leaving Facebook in favor of mobile play. Most analysts agree that Zynga has failed to make the mobile transition rapidly enough.
