The announcement is a sign that Zynga, which went public in December, "is moving from technology investment mode to harvest mode," which should ultimately improve its profit margins, the analyst said. Sebastian said the announcement was expected and is baked into Zynga's guidance. Zynga began talking last fall about its own online playground "Project Z."
Zynga plans to share feedback with developers like Mobscience about players' experiences, including how engaged they are with a particular game or how much they want to continue playing.
"Facebook has been struggling with how to handle two sets of users one set who loves games and one set who doesn't," said Michael Witz, the CEO of online game company Mobscience.
Investors may have interpreted the news as a sign that company is reducing its dependence on Facebook whether or not that is the case. Zynga's stock rose nearly 10 percent to close at $14.48 on Thursday and continued rising after hours, picking up another 76 cents, or 5.3 percent, and climbing to $15.24.
