Unlike later quiz shows, where the host asked questions to the contestants, it was the exact opposite: the contestants asked questions to the host. If the host couldn't give the correct answer, the contestant won $25.
Later broadcasts used a different format: six contestants were selected from the studio audience, and the winner of the session received, $25, with $15 given to the runners-up. On these broadcasts, listeners would send in six questions, and if they were used, they also won $25.
