Using the racing game Angry Birds GO as an example, Google showed how an iPhone can connect to a Chromecast to stream the game to a TV, and use the smartphone itself as a controller. The feature will work on both Android and iPhone games such as WGT Golf and Monopoly Here & Now. That game will also support multiplayer, which will allow up to four gamers to play on one TV with a Chromecast at the same time.
Support for Chromecast Game Casting will be rolled out over the next few months. Stay tuned for more information from Google's Nexus press event.
