Gameplay
The game can be played by one, two, or three players. (The game can be played with up to four players on the tabletop version and the console versions of "YDKJ-2011". The 2011 PC version is limited to two 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, Mock 2), and others offer only 13 questions (The Ride) or 11 questions (HeadRush, "YDKJ-2011"). 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.
