Once, they forgot to change the slides, and the contestant, on his first spin, got three JOKERS, and an obvious stop tape happened, leaving Jack to explain that they NEVER had a person spin three jokers on a first spin so the challenger was invited back to play again if the champion answered correctly.
GSN aired that episode, and it looked as if they had never considered that could occur. They didn\'t seem to have a rule for it at that time. By mid-1973, if that happened they asked the challenger to play the next game, rather than coming back later. By spring-74, they switched positions so that the challenger spun last.
