'Catch 21' situation for GSN

Alfonso Ribeiro hosts the game show

GSN is ready to play "Catch 21." The cable network has ordered 40 episodes of a game show hosted by Alfonso Ribeiro to premiere July 21.

The series, executive produced by creator Merrill Heatter and Scott Sternberg, blends pop trivia with the card game 21. Ribeiro will quiz contestants as they compete to win playing cards and try to build the closest hand to 21 for a cash prize.

An online game, created by WorldWinner, also is available at GSN.com.
