YDKJ is a game show that allows one to three contestants. But it's not your ordinary, run of the mill game show. It's irreverent, funny, and very fast-paced. You'll need a hefty pool of trivia, both classical and pop-cultural, to draw from and quick thinking to buzz in your responses to the unusual questions the host of YDKJ fires at you. You can play 7 or 21 question rounds for virtual cash but the main focus is on having fun. Employing a frenzied pace, YDKJ sacrifices glimmer graphics for a truly interactive gaming experience with original, imaginative categories and questions. Be prepared for wall to wall fun and bring a thick skin -- the host will definitely let you know when You Don't Know Jack. ~ Michael L. House, All Game Guide
