You Don't Know Jack Sports is a trivia party game co-developed by Jellyvision (now Jackbox Games) and Berkeley Systems and originally published by Sierra in 1996 for PC and Macintosh. It is framed as a quiz game show in which one to three players can compete to earn virtual cash by answering a series of trivia questions. The series is notable for its comedic presentation and dialogue, most of which is delivered by an unseen host who provides the questions as well as his own commentary.
This edition of You Don't Know Jack contains eight hundred sports-themed questions and is emceed by fictional host "Guy Towers" (voiced by Jellyvision writer/audio designer Andy Poland).
Released just over a year after the original You Don't Know Jack, the Sports edition follows its predecessor's established format with an all-new set of trivia questions covering a variety of sports-related topics. The "Screw Your Neighbor," "Don't Be A Wimp" and "Burned" features are all carried over from the original game, as well as the "Gibberish Question" and "Fiber Optic Field Trip" special question types. As with every edition of YDKJ, the final round is the Jack Attack.
