At the 2011 Consumer Electronics Show, Microsoft announced a mobile version of Game Room for Windows Phone 7.

[2] Asteroids Deluxe was the only game announced, but a show floor demo revealed working prototypes of Centipede and Shao-Lin's Road.

[3] The Game Room front end can be downloaded at no charge from Microsoft's Marketplace online storefront.

When launched, players are presented with a three-story virtual video arcade, each story containing four separate rooms.

While the packs are free to download, individual games must be purchased in order to be played fully.

Also, some games can be played in a special "ranked mode," which allows scores to be posted to online leaderboards while limiting gameplay options to a single variation common to all players, as well as disallowing several Game Room options, seemingly to prevent falsifying rankings or other forms of cheating.

As players earn medals, they can advance in levels, which will unlock new themes and set pieces to be used in their arcades.
