You Don't Know Jack is a series of party video games developed by Jackbox Games (formerly known as Jellyvision Games) and Berkeley Systems. The series began with You Don't Know Jack (1995), and combines trivia and comedy within a game show framing device.

While it is primarily a Windows and Mac-based franchise with over two dozen releases and compilations for those platforms, there have been a few entries released for consoles: two for the original PlayStation, and the 2011 release which had versions for the Xbox 360, PlayStation 3, Nintendo DS and Wii. In 2012, Jackbox Games developed and published a social version of the 2011 game on Facebook with cross-platform versions subsequently released for Roku, iOS, and Android. On November 5, 2013, Jackbox reissued the majority of the franchise's many volumes and spinoffs onto Steam.

On November 18, 2014, You Don't Know Jack 2015 was released as part of The Jackbox Party Pack on Windows, macOS, Xbox 360, Xbox One, PlayStation 3, PlayStation 4, and later Nintendo Switch, iPad, Amazon Fire TV, Android TV, Nvidia Shield, Apple TV, and Xfinity X1. On October 17, 2018, You Don't Know Jack: Full Stream was released as part of The Jackbox Party Pack 5 for the same platforms as You Don't Know Jack 2015, with the exception of PlayStation 3 and Xbox 360.

History In 1991, Jellyvision's former identity, Learn Television, released the award-winning film The Mind's Treasure Chest, which featured lead character Jack Patterson. When Learn Television sought to use new multimedia technologies to create a more active learning experience, the company teamed up with Follett Software Company and developed "That's a Fact, Jack!", a reading motivation CD-ROM game show series covering young adult fiction, targeted to 3rd through 10th graders. The game would give a title for a child to read, and then ask questions related to that title.

The idea for You Don't Know Jack began while That's a Fact, Jack! was still in development. The game's title comes from the more vulgar version of the phrase: "You don't know jack shit".

Gameplay The game can be played by up to eight players, depending on the version. All versions of the game feature the voice of an off-screen host, who reads questions aloud, provides instructions regarding special question types, and pokes fun at the players. The game usually opens with a green room segment, in which the players are prompted to enter their names and given instructions for play. Each game lasts for a number of questions, commonly 11 in later games.

The category of the questions may be pre-determined, or selected by one of the players. Most questions are multiple choice and must be answered within a time limit. Depending on the game, players answer separately or buzz in to give an answer. Correct answers award money while incorrect answers (or sometimes not answering) deduct money. The money value of each question varies across a game. There are occasionally other question types offered (see below).

Players are also given the opportunity to "screw" other players, which forces them to answer the question or make the question harder to answer. Players choosing to "screw" receive additional money if the "screwed" players answer incorrectly, but may be penalized if otherwise.

Question types The majority of You Don't Know Jack questions are multiple choice, with four possible choices. Some questions are fill-in-the-blank, requiring a typed response.

Special questions are also played during the game. Each version of You Don't Know Jack has its own different types of special questions. Some of the most common are the "DisOrDat", in which players must determine which of two categories the given subjects fall under (such as if Jay Leno was a daytime or a nighttime talk show host, if orecchiette is a type of pasta or a parasite) and the "Gibberish Question", involving a nonsensical phrase whose syllables rhyme with a more common phrase or title (for example, "Pre-empt Tires, Like Crack" could be the gibberish to The Empire Strikes Back).

Jack Attack The final round of the game, called the Jack Attack in most versions, is a word association question. A word, phrase, or name appears in the middle of the screen, to which the player must find associated words or phrases that fit the overall category. For example, Star Wars might be the associated word, and the correct answer fitting "movie stars" could be Harrison Ford. For each associated subject, several potential matches appear and the players win money by buzzing in when the correct match appears, or by selecting the correct matches.

In all versions of the game, the running total of each player's score is not shown anywhere on the screen during Jack Attack, and this part of the game is usually accompanied by ominous music or ambient sounds. This creates tension between players because of the uncertainty of ranking, and the unsettling atmosphere.

Game show theme Throughout the You Don't Know Jack franchise, there has been a running theme of You Don't Know Jack taking place on a self-titled televised game show where the players are the contestants. This idea is shown by satirical fake commercials that can be heard while starting the game, and in most games, after the game has finished.
