Using the "screw" forces the opponent to give an answer to a question within ten seconds. If the player who is "screwed" answers correctly, they win the money while the player who "screwed" them 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. 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. The player being "screwed" must then answer, even though the question may no longer be readable. In German-language versions of the series, the "screw" is replaced by a "nail" which serves the same purpose. In "You Don't Know Jack: Full Stream", either one or two screws (depending on the total number of players in the game, not counting Audience members) could be awarded in one of two ways: (1) they could be given to the player(s) who gave the fewest correct answers in the "Dis or Dat" round; and (2) to the lowest-scoring player(s) at the break starting Round Two. (Several factors—too numerous to name here—determined how many screws would be awarded in each case, and players could only hold one screw at a time.) Unlike previous versions of the game, screws can affect all other players instead of just one (most notably if they have not yet answered before the screw is activated), and they make the question more difficult to answer for the players instead of forcing the them to answer within a short amount of time. Examples include removing all vowels from the answers, flipping the text upside-down on their devices, making the text of the question and the answers on the player's devices extremely small or large, or bouncing the answers around the screen in the style of a screensaver program. Others include forcing the players to enter a password, scroll through an excessively long "Terms of Service" form, or choosing a new screen name before being able to select an answer. 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 initially varied between $1,000, $2,000, & $3,000, and were doubled during the second round of questions.
