"Crazy Frog Racer" European Video Game Sensation to Launch in North America by Graffiti Entertainment Subsidiary of Signature Devices

The Outrageously Popular "Annoying Thing's" Video Game Leaps Across the Pond May 22, 2006 as Part of Major Rollout

Signature Devices, Inc. (OTC: SDVI) (www.signaturedevices.com) interactive game publishing subsidiary, Graffiti Entertainment LLC (www.graffitientertainment.com), on May 22, 2006 will launch the PC version of the video game in North America that features Europe's most outrageously popular animated character, "Crazy Frog" (www.crazyfroggame.com). Releases of console versions are scheduled later in the year.

"Crazy Frog Racer" is the third video game the company will market since forming its publishing subsidiary less than two months ago. It previously announced worldwide publishing rights to "Mazes of Fate," a chaotic world of dark dungeons and wicked warfare for the Game Boy® Advance hand-held video game system; and "Strike Force Red Cell," a counter-terrorist game where terrorists are fought in a real world first person shooter environment for the PC and XBOX 360 Console.

The high-speed, high-octane Crazy Frog Racer game (http://www.crazyfroggame.com) is licensed from Mercury Games Ltd. It is based on the phenomenal success of the animated cell phone ring-tone frog-like character "The Annoying Thing(TM)" that is aggravating his way into mainstream popularity -- starting with 12 million ring-tone downloads worldwide. The Crazy Frog Axel F single tune has reached number one in over 20 countries. Its album received 2.5 million pre-orders in the United Kingdom alone. The Crazy Frog Racer video game that is being introduced here was this past Christmas' number one seller in both the Playstation and All Formats in the UK.

According to Mercury games, the licensor, as part of its North American debut, the Cartoon Network will be running the Crazy Frog music video that features the Axel F Tune. It has already been the most requested song on Disney Radio for several weeks. Over 60 merchandise items that range from MP3 players, radios, and plush toys are being launched in May to US retailers, such as Wal-Mart, Best Buy, and Target. Also anticipated during May, Jamster, where the phenomena started, will provide content for the US market.

"Our ability to acquire publishing rights from superior developers, especially those with a franchise character as well known and popular as Crazy Frog, clearly demonstrates how rapidly we have made the transition from developing games for some of the best known publishers, to becoming an integrated developer and publisher of world-class interactive entertainment games for the most popular platforms," says Ken Hurley, CEO of both Signature Devices and Graffiti Entertainment. "We are extremely pleased that Mercury Games selected us to publish its Crazy Frog Racer game throughout North America. We are delighted to work with them to build the Crazy Frog brand franchise by successfully marketing the Crazy Frog Racer game here."

The Crazy Frog Racer game features the wild amphibian and his friends in a madcap ride through cities and underground chaos, blasting opponents while grabbing zany power ups, and super boosts. Its special features include:

--  Over 8 playable characters, including the one and only Crazy Frog and
    unlock many more!

--  Twelve twisting tracks and 3 arenas including the environment from the
    Axel F Crazy Frog video.
