Double Dare (1976 game show)
Two contestants (players) would compete in a game of knowledge. One was a returning winner from a previous game, the other a new challenger. A contestant was given the chance to answer the question and win money. Or, they could challenge the other contestant to answer the question. If the second contestant answered the question correctly, he or she won the money. If answered incorrectly, the first contestant got double the money. Questions were answered from an isolation booth.
