The third bonus round was used for the entire final year of the show's run, from September 2, 1968, to September 26, 1969. Hidden behind spaces 1–3 and 6–8 were five "Go" cards and one "Stop!" sign (spaces 4 and 5 were not used in this format). Prizes of increasing value were awarded after each "Go" card was found. The contestant could stop at any point but lost all the prizes accumulated if the "Stop!" card was revealed. If all five "Go" cards were revealed without finding the "Stop!" card, the contestant won a new car.
