LOS ANGELES--(BUSINESS WIRE)--March 2, 2004

Wireless entertainment publisher JAMDAT Mobile Inc., announced today it has signed a worldwide publishing agreement with GameHouse(R) Studios, a division of RealNetworks(R), Inc., and leading provider of mass-market Internet games, to bring popular game titles Collapse!(R), Collapse! Strategy, Bounce Out(TM) and TextTwist(R) to mobile phones.

"These GameHouse titles expand JAMDAT's robust slate of casual products," said Mitch Lasky, CEO of JAMDAT Mobile Inc. "The easy-to-use gameplay is well suited for mobile users who enjoy casual puzzle games, anytime, anywhere."

"By collaborating with JAMDAT, who provides a strong carrier network and seamless gameplay experience, we are excited to create a completely new mobile community of Collapse! fans," said Garr Godfrey, General Manager of GameHouse Studios. "Collapse! is the most popular game download franchise on the Internet with over 15 million downloads worldwide. Now, players will be able to experience mobile versions of Collapse!, Collapse! Strategy, TextTwist and Bounce Out games on their mobile phones, which will be similar to the gameplay of the online and PC versions."

Collapse! is the first title to be released. It's currently available from AT&T Wireless and Verizon Wireless. JAMDAT anticipates that it will be launching soon on Cingular Wireless, Midwest Wireless, Sprint and US Cellular.

GAME DESCRIPTIONS

Collapse! is a race against an ever-growing foundation of blocks. Players must clear the blocks and collect points before they reach the top of the screen. Game pace accelerates as players progress to new levels.

Collapse! Strategy requires game players to think strategically about each block they remove because new blocks will appear after each move. There's no time limit, but the wrong strategy will lead to blocks reaching the top of the screen faster than they can be cleared.

TextTwist challenges players to use a set of 6 letters to form as many words as possible within a time limit before moving to the next level. When the player gets stuck they can always get a hint by pushing the "Twist" button.

Bounce Out tests players' ability to swap balls to create rows of three or more. Players move the balls to line-up as large a combination as possible to score points before time runs out.
