Its beta app on the social-networking site launched Wednesday with seven games that players can try for free. The games available: Saints Row - The Third, Dead Rising 2 - Off the Record, Magicka, Sniper - Ghost Warrior, The Witcher 2 - Assassins of Kings, Orcs Must Die! and Farming Simulator 2011.

"People don't want to leave Facebook to play games – Zynga's phenomenal success is proof of that," said Gaikai CEO David Perry in a statement. "Cloud Gaming means that the game doesn't need to be downloaded and run on your computer, it literally means the game runs out on the Internet, in the cloud, with the experience being streamed to the players. Most video game publishers are now seeking to grow their digital customer base and unlike movie and music services like Netflix and Spotify, Gaikai gives the game publishers relationships with the customers."
