BlackBerry® Smartphones Now Playing No. 1 Card Game UNO® Classic 2007

August 31, 2007 – Oasys Mobile, Inc, a leading provider of premium mobile media content, products and services, along with Concrete Software®, a leader in innovative mobile content, today announced the availability of UNO® Classic 2007, an Oasys Mobile game on all color BlackBerry® smartphones including the new BlackBerry® Curve™ and the BlackBerry® Pearl™ models from Research In Motion (RIM) (Nasdaq: RIMM). The game is sold through most carriers and major websites that carry content for BlackBerry smartphones.

UNO®, a game from Mattel, is the No. 1 card game in America. UNO® Classic 2007 offers an experience that reflects the social core of this classic card game. Just like the traditional UNO® game, the mobile version is a race to get rid of all your cards. This easy to pick up game is fun for mobile gamers across all cultural, gender and generational backgrounds.

“We are thrilled to now offer one of our best selling games to Blackberry customers,” said Oasys Mobile CEO, Doug Dyer. “We believe this is an untapped market that has great potential for us and plan to release additional titles throughout 2007.”

With BlackBerry smartphones becoming more popular and attracting more users, there is a natural demand for games like UNO® Classic 2007. The BlackBerry smartphone's larger than average mobile screen size, full keyboard, and easy navigation make playing this type of card game fun and entertaining, no matter where you go.

"We are very excited about being able to bring such a powerful brand to the market on BlackBerry smartphones," said Keith Pichelman, CEO of Concrete Software. "UNO Classic 2007 is a top selling game on many platforms. We have very high expectations for the BlackBerry platform as well."
