The amendments change the companies' 2010 contract that gave Zynga special status among Facebook game developers. Zynga relies on Facebook for most of the revenue it generates, but the company has been working to establish its independence — while also maintaining ties with Facebook.

Zynga's titles range from "FarmVille" to "CityVille" to "Words With Friends," the Scrabble-like game made popular on mobile devices.

Zynga shares fell 33 cents, or 12.6 percent, to $2.29 in after-hours trading. The stock closed up 11 cents, or 4.4 percent, at $2.62 in the regular session.

Facebook shares dipped 4 cents to $27.28 in extended trading. Its stock has surged by nearly 30 percent this month on increasing optimism about the company's ability to make money on the traffic visiting its service on smartphones and tablet computers.
