Two well-known professional bowlers attempted to convert five spares with point values that increased according to difficulty. The 2-4-5-8 and 1-2-4-7 scored 25 points, the 4-5 and 1-2-7-10 scored 50 points, and the 5-7 scored 100 points. The winner of the competition was given one opportunity to convert the "sweepstakes spare" (the 6-7-8-10) for a prize of $5,000 or more. In later years, a new Ford Mustang was offered as the prize for converting the sweepstakes spare.
