Jeopardy! is a game show created by the game show great Merv Griffin. Contestants pick from six categories, ranging from science, to pop culture, to language puzzles. Each column of categories has five dollar amounts to pick from. Each dollar amount gives a clue in the form of an answer and the player must present a question (Who is?...What is?...etc.) Guessing correctly gives the player that dollar amount but an incorrect guess subtracts it. There are three rounds, Jeopardy, Double Jeopardy, where dollar amounts are doubled, and final Jeopardy, where the players must wager an amount of money and give a correct answer for one clue.
