The highest scorer won $1,000 and the right to convert a "sweepstakes spare" worth a minimum of $5,000; making all five spares in the main game earned an additional $1,000 bonus. The loser also received a check for a lesser, unspecified "loser's share". In early seasons, the sweepstakes spare was always the 6-7-8-10; this was later changed to a randomly chosen spare. If this spare was not converted on a given program, $1,000 was added for the following week until won. In 1964, making the sweepstakes spare won a Ford Mustang. The winner of each weekly episode also earned the right to return the following week to defend his championship against a new challenger.
