You Don't Know Jack (Facebook game)

You Don't Know Jack (Facebook game) was a social trivia game available on Facebook, developed by Jellyvision. It was a version of the popular You Don't Know Jack franchise, adapted for the social networking platform. The game retained the series' signature irreverent humor, fast-paced gameplay, and challenging trivia questions covering a wide range of topics.

The Facebook version allowed players to compete against their friends or other online players in real-time trivia matches. Players earned points for answering questions correctly and quickly, and the game featured various question types, including DisOrDat, Gibberish Questions, and the Wrong Answer of the Game.

The game integrated social features such as leaderboards and the ability to challenge friends. Like other Facebook games, it frequently featured in-app purchases, typically for virtual currency used to acquire advantages or cosmetic items.

The Facebook version of You Don't Know Jack is no longer playable, as it was discontinued when Facebook ceased supporting Flash-based games and as Jellyvision shifted its focus to other platforms and business models.
