"You Don't Know Jack" (commonly abbreviated "YDKJ") is a series of computer games developed by Jellyvision and Berkeley Systems, as well as the title of the first game in the series. "YDKJ", promoted as the games "where high culture and pop culture collide", combine trivia with comedy. The series' title is based on the phrase, "You don't know jack shit", which means "you don't know anything/everything".

The games are known for their humor and challenge, as well as simple presentation. The games are presented as if they are a television game show, complete with an emcee who is heard, but not seen. Players compete for a monetary score by answering trivia questions. With some rare exceptions, the games never use graphics, and instead rely only on animated text art for visual content. This was not a purely stylistic choice; the game was designed to minimise the amount of disc accessing needed by keeping files small.


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.

With "That's a Fact, Jack!" in development, Jellyvision decided to test the waters of mainstream interactive entertainment by beginning a partnership with Berkeley Systems and developing the game You Don't Know Jack, with first title released in the fall of 1995. [ [ Company History] ] Jellyvision's website has this explanation as to why You Don't Know Jack was made:

"Way back in the early-90s, Jellyvision decided to test the waters of mainstream interactive entertainment by beginning a partnership with Berkeley Systems, of "Flying Toasters" fame. Berkeley Systems asked us if we could apply the concepts of a game show to an adult trivia game. Since no one at Jellyvision at the time actually liked trivia games, we tried to figure out how to make trivia questions fun and engaging to us. When we realized that it was possible to ask about both Shakespeare and Scooby Doo in the same question, YOU DON'T KNOW JACK was born." [ [ YDKJ Information Page] ]


The game can be played by one, two, or three players. 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. The audio during this segment includes rehearsing singers, a busy producer, and a harassed studio manager/host. The only graphics are a large "On Air/Stand By" sign in the middle of the screen, visual representations of the players' button assignments, and a box for name entry.

Most versions of "YDKJ" offer the choice of playing a 7- or 21-question game; some versions offer only 15 questions ("Netshow", "LFF", "5th Dementia"), and others offer only 13 questions ("The Ride") or 11 questions ("HeadRush"). The latest games are now only 7 questions ("The Lost Gold", online game). In a 21-question game, there is a brief intermission after the tenth question. Most questions are multiple choice, with some occasional free-entry questions, or mini-games.

Before each question, one player is given a choice of three categories. Each has a humorous title that has some connection to the topic of the corresponding question. After a short animated introduction, which is often accompanied with a sung jingle about the question number, the host asks the question. Typically, the question is multiple choice, and the first player to "buzz in" and give the correct answer wins the money for that question and gets to choose the next category. If a player answers incorrectly, he or she loses money, but not before the host wisecracks about it. There are occasionally other question types offered (see below).

In multi-player games, each player is allowed one chance to "screw" an opponent in each half of a full game, or once in an entire short game. Using the "screw" forces the opponent to give an answer to a question within ten seconds. If the player who is "screwed" answers correctly, he or she wins the money while the player who "screwed" him or her loses money. This basic design has changed slightly in some versions of the game. For example, in the teen spinoff "HeadRush", the screws are replaced by pairs of false teeth, so players "bite" their opponent instead, and in "The Ride," instead of just forcing an opponent to answer, players engage in "FlakJack", where they launch multiple screws into the screen (partially or totally obscuring the question), then force another player to answer the question, even though it may be unreadable.

In the previous games, different category options were worth differing amounts of money, which was revealed after a category was chosen. This amount indicated how difficult the question would be. Amounts included $1,000, $2,000, & $3,000, and were doubled during the second round of questions. However, early volumes of the series occasionally featured questions hosted by guests spawned from Fiber Optic Field Trips and Celebrity Collect Calls; these were worth $5,000 and appeared as the first question of the second round. Later games in the series opted not to give players three randomly generated questions; now giving a set amount of questions in a set order. Instead of random questions, players 'buzz in' to set the amount of money the question is worth. Some questions may only be worth a few hundred dollars, while some may be over $10,000.

Some of the volumes have a feature called "Don't Be a Wimp", which is activated if one player has a very large lead. If no one answers a question, the host may deride the leading player, calling on the audience to shout "Don't be a wimp!", and forcing the leader to answer the question.

In some volumes, the host also punishes a player who buzzes in too early; the question and possible answers disappear, leaving the player with ten seconds to type the answer. For "The Ride", this is replaced by a different punishment: the player is forced to pick from a list of four answers, all of which are wrong. This punishment is only triggered if a player buzzes in at the very instant that the question appears on the screen. In both instances, the player that buzzed in CANNOT "screw" the other players.

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 "YDKJ" has its own different types of special questions, but some of the most common are:
* DisOrDat: Featured in all versions except "Vol.1" and "Sports", the DisOrDat is only played by one player, with a 30-second time limit. The player is given two categories and seven different subjects, and it is up to the player to determine which category the subject falls under (or, in some cases, whether the subject fits both categories). For example, a player might have to determine if Jay Leno was a daytime or a nighttime talk show host, or if orecchiette is a type of pasta or a parasite.
* Gibberish Questions: Featured in all PC versions except "HeadRush". Players are given a mondegreen: a nonsensical phrase that rhymes with a more common phrase or title. For example, "Pre-empt Tires, Like Crack" could be the gibberish to "". The first player to buzz in and type the correct answer wins the money. Clues are given as time passes, but the amount of money the player can win decreases by 5% of the initial starting value with every 1.5 seconds that elapse.
* Anagram Questions: These exist only in "5th Dimentia" and "The Lost Gold", and follow the same rules as the Gibberish Questions; however, instead of trying to figure out a rhyme, players must rearrange the letters given into a saying, name, or other group (as in the famous example of "genuine class" being an anagram of "Alec Guinness").
* HeadButt: Only existing in "HeadRush", these also follow the rules of the Gibberish Questions. Players are given a word equation such as "color of pickles + opposite of night" and have to put it together to form a name or other group (in this case, the color of pickles is "Green", and the opposite of night is "Day", so the answer would be "Green Day").
* Fiber Optic Field Trip: These only exist in "Vol.1", "Sports", "Vol.2", and "Movies", and only appear in full-length (21-question) games. A random person is called from out of the phonebook and asked to come up with a trivia question. Fiber Optic Field Trips are initiated during the first half of the game, and the trivia question hosted by the special guest is the first question of the second half.
* Celebrity Collect Call: These exist in "Vol.2" only and follow the same basic format as the Fiber Optic Field Trips. The host calls a celebrity who is asked to come up with a question. Celebrities include Tim Allen, Florence Henderson, and Vanessa A. Williams. Sometimes, the conversation between the host and the celebrity lasts a very long time.
* Pub Quiz: This replaces the Fiber Optic Field Trips and Celebrity Collect Calls in the British edition of the game. Instead of calling a random person in a city, the host calls a bartender in a random pub within the UK to host the question.
* Trash Talkin' with Milan: Only existing in "HeadRush", "Milan the Janitor" (voiced by Igor Gasowski) hosts a standard multiple choice question about grammar.
* Bug Out: This exists only in "5th Dementia". The goal is simple: Bugs will crawl and display a choice. When you see a choice that doesn't match the clue, buzz in. If you're right, your opponents pay you money. If you're wrong, you pay your opponents.
* Fill in the Blank: Instead of having four answers to choose from, you have to type the answer out.
* Pissed About A Question: This exists in both "Offline" volumes. Jellyvision creates new questions about angry letters they've received from irritated players.
* Road Kill/Coinkydink: Exists in "The Ride" (as RoadKill) and "Mock 2" (as Coinkydink). In this fast-paced question type, you're given two clues. A series of words fly by and you have to buzz in when the word that connects the two is on the screen. A bonus is given at the end if the commonality of all the answers is selected.
* Jack BINGO: This exists only in "The Ride". Here, you are given a five-letter word followed by a series of clues. Your job is to buzz in when the first letter of the answer is lit up. If you collect all five letters, you get the bonus prize.
* ThreeWay: Found only in "Vol.3" and the first PlayStation version. Players are given three words that have something in common and several clues that only relate to one of the words. Players must match the clues to the proper words.
* Wendithap'n: This only exists in "Louder! Faster! Funner!" and "Mock 2" and follow the same rules as the ThreeWay. In this question type, you are given an event, followed by several more events which you have to decide when it happened in relation to the main event: Before, after, or if it never happened at all.
* Guest Host Question: Someone else hosts and gives a question.
* Impossible Questions: Only appearing in "Vol.3" and the first PlayStation version, Impossible questions are worth very large amounts of money, but as the name implies, they are very, very difficult. An example of an impossible question is one which asks the players what the word 'pyrrhic' means: even if answered correctly, the player still loses that amount of money, in keeping with the meaning of the word "Pyrrhic".
* Super Audio Question: A sound will play, and you'll be asked questions about it.
* Whatshisname Question: In this question, the host is trying to remember a certain someone's name. They'll give you a bunch of clues and you have to buzz in and type in the name. In "HeadRush", this question type is known as Old Man's Moldy Memories and the character of "Old Man", voiced by Andy Poland, hosts the question.
* Picture Question: In this question, you are shown a picture and then asked a question about it.

The Final Round

The final round of the game, called the HeadRush in "HeadRush" and known as the Jack Attack in all other "YDKJ" volumes, is a word association question. A clue is given, which generally describes the desired correct answers (such as "movie stars") and after that a word, phrase, or name appears in the middle of the screen, to which the contestant must find an associated word or phrase that fits the overall category. For example, "Star Wars" might be the associated word, and the correct answer fitting "movie stars" could be Harrison Ford. Other possibilities offered might include actors not in that film, or other objects or concepts related to the film but which are not stars of the movie. Potential matches appear on screen one-at-a-time for only a few seconds each before disappearing, and only one is correct. The topics and/or potential answers are sometimes humorous.

Players win money ($2,000 in most "YDKJ" volumes; $5,000 in "HeadRush") if they buzz in when the correct match is displayed on the screen. An incorrect guess deducts money from the player's score...not just once, but "every" time the player buzzes in incorrectly. Multiple players play simultaneously, playing to the same words.

The winner of the game is crowned after the seventh word is matched, or the contestants take too long to reach that point.


One of the unique features of the game takes place after it has ended. Before you start a new game, you can choose to listen to YDKJ staff performing parodies of various radio commercials. The commercials vary in absurdity, selling products such as scented suppositories or foreign language cassettes to help you learn how to speak American.

They also featured phony news stories about everyday things. Examples: "Oxygen: Gas of Life? or Secret Military Death-Vapor?" or "People are falling unconscious for 8 hours every night. What is the 'sleeping disease'? Do you have it? Find out tonight."

Most "YDKJ" games feature recurring characters like "Chocky the Chipmunk", a breakfast cereal mascot with the catchphrase "Gotta motor!" or "Xenora: Queen of Battle", a parody of Xena, Warrior Princess that gets involved in overtly erotic situations.

The First CD-ROM for "The Ride" features a CD of a selection of these commercials from the previous games in the series. The Disk was titled "You Don't Hear Jack" and has since been released as a separate product on CD.


There have been many different hosts of You Don't Know Jack over the years. The following is a list of hosts and the games they appear in.

* Nate Shapiro, voiced by Harry Gottlieb: Nate Shapiro was the first host of the series. He hosts "Vol. 1", "the Netshow", the tabletop game, and hosts for part of "YDKJ: The Ride". He is not to be confused with "Nate the Intern" from the current Flash incarnation (voiced by Production & SQA Coordinator Nathan Fernald).

He hosts "Movies", "Vol. 3", "the Netshow", the first Playstation version, part of "The Ride", and "Offline". He also was the announcer for the "YDKJ" TV show in 2001. He also hosts the newer webshows and daily DisOrDats that started appearing on the YDKJ website in December 2006.

Rumored for the Wii

On 16 June 2008, it was leaked that You Don't Know Jack is all but confirmed for a new release on the Nintendo Wii video game system. While no date has been released, a price of $40 was part of the leak. [ [ Rumor: You Don't Know Jack Probably Announced For The Wii ] ]

Other media

During the 2000 presidential election, Sierra On-Line president David Grenewetzki challenged the presidential candidates to play a political version of YDKJ. The game had been distributed to a few radio stations, and was described as a "litmus test" of the candidates' political knowledge.

YDJK also appeared as two books: "You Don't Know Jack: The Book" and "You Don't Know Jack: The TV Book". Both were published in 2001.

"You Don't Know Jack" was briefly aired as an actual television game show in 2001 on ABC. [imdb title|0287898 (2001 television game show)] Starring Paul Reubens (best known for his role as Pee Wee Herman) as over-the-top game show host Troy Stevens, with 'Cookie' as the announcer. The show lasted only six episodes.

After the "You Don't Know Jack" TV show ended, another show from the makers of YDKJ called Smush aired on USA Network. It was a game of taking two or more words and combining them into one long word. The show started late at night, but was later pushed to later and later times, even up to 3:00 A.M.; until it was eventually canceled.

In 2001, AMC released "You Don't Know Jack about MonsterFest", an online game on their website hosted by Schmitty, and the MonsterFest movie marathon was hosted by Clive Barker and Carmen Electra, who gave clues for the game.


There are three particular cheat codes for YDKJ.

Demo mode: if you push the letter D at the beginning of the game when it says "Press Esc for volume control and other options", you will see the words "Demo Mode Activated".

Gibberish Question Cheat: if you answer by typing in "Fuck You" on any Gibberish Question, the host will get very mad. Volume one is the only edition where the host curses back. The host will sometimes take away $50,000 or $100,000. He may also change your name to something insulting like "Jerk". If you do it again the host will do nothing with your score and say that typing it in is not original anymore and will only take away your turn. If you do it for a third time, the host will get so mad he will make the game close and you will return to your desktop.

At the end of the game, if you press the letter B during the credits, you unlock bloopers during the recordings of the booth.


The hosts of YDKJ have never shown their faces on-screen, and even upon reaching 'The Bottom' in YDKJ: The Ride, the hosts only reveal the bottom half of their faces.
