Catch Me if You Can was an early version of Hit the Jackpot.
CBS Radio (Weekly): 5/9/1948 – 6/13/1948
On this show, a "climber" answered questions to move up rungs of a ladder. A second contestant, the "challenger", could eliminate the climber by challenging his answer and providing the correct one. A successful challenge meant that the challenger then became the climber, and a new challenger was introduced. Any player who reached the top rung of the ladder reached the Golden Door and the opportunity to unravel a mystery sentence for a merchandise jackpot.
