 If a contestant did not win the jackpot, but won five games, they played an altered "two-box" game with no bribes – one box contained the jackpot (guaranteed to be at least $3,000), while the other contained the car.The three-box bonus round format resembles the Monty Hall problem, which was made famous on "Let's Make a Deal".Both versions are presumed to be destroyed as per practices at the time.
