Television game network GSN and Cellufun, an ad-supported mobile games community, partnered to bring Catch 21 to mobile.

Catch 21, which premiered on GSN yesterday, is already available on GSN.com as a free Flash game hosted by WorldWinner, as well as on AOL's Games.com. There is also a cash competition version on WorldWinner.com and GSN.com.

"This is an opportunity for Worldwinner and GSN to promote their new show and generate brand awareness in a nontraditional, effective way," Keith Katz, vice president of marketing for Cellufun.

"GSN will be able to leverage the audience's engagement with both the Web and their mobile handsets to promote the Catch 21 show," he said.

Catch 21, a game that combines pop-trivia with the card game 21, is now being aired on GSN, a network that broadcasts game show series. Cellufun will provide the mobile platform to take the game from the television and computer screens to the mobile screen.

The partnership is a great example of how brands are moving towards a three-screen strategy in their marketing efforts, Mr. Katz said. With the mobile component in place, Catch 21 will be launched concurrently on the PC, TV and mobile platforms.

Users can access the Catch21 game on their mobile web browsers at http://gsn.cellufun.com or text Catch to 95495.

In order to play, users must have a data plan. Additional data charges may apply.

WorldWinner hosts online competitions for popular games such as Solitaire, Bejeweled 2, Family Feud, Scrabble Cubes and Cubis. Players compete for cash and various other prizes.

Cellufun, the mobile gaming community, provides free games in a social networking atmosphere. People can play their favorite games, while chatting to people from all over the world.

Game content provider GSN distributes competition programming to its estimated 66 million viewers and to its online gaming audience. GSN features classic game show programming, as well as original content.

"This is a great opportunity for Cellufun to demonstrate how it can create customizable, integrated marketing solutions for a variety of brands," Mr. Katz said.
