$10,000 Pyramid (1973)

The object of the game is simple...to get to the top of the Pyramid (aka "Winner's Circle") in the shortest time possible. But to do so, contestants must face celebrities (and vice versa) by naming as many answers in a particular category as possible within 30 seconds. If a contestant wins the main game, they get the right to go to the Winner's Circle to try for the grand prize, which throughout the series has ranged from $10,000 to $25,000. The most popular incarnation of the series has been "The $100,000 Pyramid", where three top contestants who have gone to the pyramid in the shortest amount of time return for a Tournament Of Champions, which the grand prize is $100,000.
