I'll Bet
I'll Bet is an American game show that ran on NBC from March 29 to September 24, 1965. The series was created by Ralph Andrews, and hosted by Jack Narz. The series was a precursor to It's Your Bet.
Gameplay
Two celebrity couples played. Before taping, one member of each couple drew a name of whom they were playing for, but only the TV station of where that person watches the show was revealed until the end.A separating wall first divided the couple so they could not see what the other bet. One half of the couple was told a question through an earpiece. Afterward, he/she made a bet on whether their partner would answer the question right or wrong.
Narz then read the question to the other half of the couple. The amount of dollars won or lost depended on the bet and the number of dollars risked. After this, the other couple went through the same process; the men then took their turns at hearing the question, and so on.
A couple won either by scoring $200 themselves, or if their opponents lost $200.
