You Don't Know Jack is a series of quiz show-inspired computer games which combine trivia and comedy. The games are known for their humor and challenge, as well as simple presentation. The games rarely use graphics, relying heavily on voice acting and text.

The games have recently been revived at the YDKJ official website, where new episodes are released every weekday. These are developed in Flash and are available to play for free within your web browser.
