GameHouse and Mattel Take UNO™ Live on Facebook® Platform

SAN FRANCISCO — March 25, 2009 — From the Game Developers Conference® in San Francisco, GameHouse®, the casual games development studio of RealNetworks®, Inc. (NASDAQ: RNWK), and Mattel, Inc. today announced the availability of UNO™ BETA on Facebook. This social game adaptation of America's number one card game was developed as part of Real and Mattel's exclusive multi-year agreement, following the release of SCRABBLE® Worldwide on Facebook Platform last year.

"Through our partnership with Real, we're able to bring popular brands like UNO to longstanding fans in a new way, while also reaching new players around the globe," said Cynthia Neiman, vice president of marketing for the Mattel Digital Network. "UNO for Facebook offers a new, interactive experience that people will love, combined with the addictive fun that's been attracting players to the game for nearly 40 years."

Since it was introduced by Mattel in 1971, more than 200 million UNO® games have been sold, in more than 80 countries. Launched by GameHouse just a few weeks ago, the UNO™ Facebook application is a digital adaptation of this popular card game that lets Facebook users around the world connect for a little friendly competition and fun. To date, GameHouse has served more than 250,000 games of UNO to players in 134 countries, with someone new trying their first game every 30 seconds.

In the game of UNO™, players use a deck of 112 playing cards featuring four different suits in four bright colors that include moves like "Draw Two," "Skip" or "Draw Four Wild." These simple commands can move a player to the top of the winner's circle or to the bottom of the deck. In the Facebook application, four players compete to be the first to use up all the cards in their hands. Points are won based on the cards left in all your opponents' hands, and every player has a best round score that they constantly strive to beat. While the Facebook application tracks player progress over time and names a winner after each round, in the original card game players compete in back to back games to be the first to reach 500 points and claim victory.

"Who doesn't have fond memories of playing UNO?" asks Matt Turetzky, vice president of RealGames. "With the perfect balance of fun and simplicity, UNO has the essential ingredients of a great casual game, and we're excited to partner with Mattel in taking this family favorite to the social space for Facebook users."

RealGames is a leader in the casual games industry worldwide and develops games for multiple platforms, with a vertically integrated development, publishing, licensing, distribution and retail business.

Facebook users can find UNO™ on Facebook at http://apps.facebook.com/liveuno/. GameHouse's other offerings on Facebook include SCRABBLE® and TextTwist®.
