Double Dare (1976)
Two contestants are placed in soundproof isolation booths. A subject is shown to the studio and home audiences. Clues are now shown one at a time to the contestants. The contestant ringing in closes off his/her opponent from sight and sound and tries to identify the subject. If wrong, the opponent's booth is reopened and play continues. If correct, the player scores $50 and now dares the opponent to identify the subject on the next clue for $100. If the dare is successful, the player can double dare the opponent to identify the subject on the next clue for $200. The opponent scores the money if he/she identifies the subject on the dare or double dare.
The contestant reaching $500 first wins the game and plays for $5000 against a team of Ph.D.'s in isolation booths called "The Spoilers." The contestant is shown a subject and then selects five of ten clues to pose to the Spoilers. Each Spoiler earns $100 if they get the subject correct. If the contestant can stump at least one Spoiler in 5 clues, he/she wins $5000.
