Master Key

This game show sees contestants solve word puzzles, similar to those used in Hangman, to win cash and prizes determined by spinning a giant carnival wheel.

A contestant must choose from 26 sealed briefcases containing a marker for various amounts of cash from one penny to $1 million. The player then eliminates the remaining 25 cases one by one. The chosen ones are opened and the amount of money inside revealed. After several cases are opened, the player is tempted by the Banker to accept an offer of cash in exchange for not continuing the game and possibly winning a larger sum of money.

Four panelists must determine guests' occupations - and, in the case of famous guests, while blindfolded, their identity - by asking only "yes" or "no" questions.

America's favorite quiz show where contestants are presented with general knowledge clues in the form of answers, and must phrase their responses in question form.
