Once more, Zynga (NASDAQ:ZNGA) is getting clobbered. The stock was down more than 6% on Friday after filing a revised partnership agreement with Facebook (NASDAQ:FB) that ensures Zynga's freedom to develop games for other platforms, but at the price of granting its benefactor the right to pursue game development in-house -- should it ever want to. Shares of Facebook were up slightly in Friday morning trading.

Investors' nervousness is understandable. Existing efforts to place games on Facebook competitors such as Google+ have done little to boost growth. Meanwhile, in its latest 10-Q quarterly filing, Zynga disclosed that 80% of its quarterly bookings and 84% of revenue could be traced directly to its relationship with Facebook. The FarmVille creator is risking a lot in seeking to go solo.

Can Zynga make this deal work for shareholders? How about Facebook? Fool contributor Tim Beyers addresses these question and more in the following video.
