Additional prizes went to some listeners who sent in questions that were used on the air.^[4] Each winner received $25 in silver dollars, and the runner-up received 15 silver dollars.^[2].By September 1947, more than 2500 contestants had received more than $100,000 on the program.^[5]

In February 1940, a Professor Quiz home game was available with the purchase of a bottle of Teel (a liquid dentifrice). The game included a 52-page book that contained 600 questions from the radio program and a spinner that players used to select questions.^[7]
