 2 contestants, 1 a returning champion competed in this general knowledge quiz married to elements of casino-style slot machines. Host Barry (later Peck, Cullen & Finn) announced a series of 5 categories from which the questions were taken. In turn, each contestant pulled a huge lever, setting into motion for the 3 reels containing the category names and jokers. The dollar values of each category depended on what category was chosen and how many times it appeared in the windows {From the Debut: $25 for 1 Category, $50 for a Pair & $100 for a Triple. Early in the Run: $50 for 1 Category, $100 for a Pair & $150 for a Triple & Late in the Run: $50 for 1 Category, $100 for a Pair & $200 for a Triple.} The "Jokers," however, served as wild cards and could be used with any category that appeared in the windows; a player could also elect to go "off the board" with any of the other categories in play. Correct answers to questions won cash, while an wrong answer gave the player s opponent a chance to answer and pick up the cash value of the question. Any player spinning a "triple Joker" at any time meant an automatic win, provided he/she answered one question from any of the five categories in play. The first player to $500 won the game and played a bonus round for a prize package; the loser got nothing. During the CBS run, The Champion spin for Prizes and 1 Circle Car to win & Later the champion spun the Joker Machine up to three times for prizes each time risking what had already won on the chance he/she might cause a devil to appear in the windows and lose what had been won. Three-time winners won a Joker s Jackpot, which began at $2500 and increased in value until someone won it; the Jackpot grew by defeated champions  depositing their cash winnings into the jackpot and the Limit is $25,000 In 1973-1975 The New Bonus Game called Play against the Devil for winning $1000 plus the Prize Package added to the Champion s Winnings (see below). During the 1977-86 syndicated run, the Joker Machine contained dollar amounts (in multiples of $25, valued between $25 and $200) and devils. Contestants reaching $1000 won the cash and a prize package while a devil forfeited everything accumulated during that bonus round. Also during the syndicated version, some categories had special rules, which could be used to help contestants win a game or play catch-up while spinning a natural triple won an assortment of prizes which grew in dollar value until claimed.
