As you can see, so far there are 35 games designed to be played in the web browser, the catch is that not all of the games were designed to support the Xbox One controller, but all the games featured on XboxIE.com are playable in your Xbox One. Also remember that these games do not save any information to Xbox Live, so no achievements or other gold benefits. For more information visit http://xboxie.com/about.
