Gameplay
Five contestants, one of them a returning champion (or designate), competed and were spotted $50 at the start of the game. Before each round, they were each given a booklet containing the questions and answers to be used in that round. The time they had to study the material varied per round. Once the study time period elapsed, the show's assistants collected the booklets, and Garagiola began randomly asking questions from the booklet.
The champion – who was seated in the number 1 position – could elect to answer or call out an opponent's number (2 through 5). That player could answer or call any of his/her opponents to answer, and so on until a time's up buzzer sounded. At that time, the player at that moment had to answer. A correct answer was worth $5, a wrong answer lost that amount. Play continued in similar fashion until all the questions were exhausted.
Subsequent rounds were played with increased stakes ($10 in Round 2, $20 in Round 3 and all future rounds). The winner at the end of the show won a $1,000 bonus and returned the next day to meet new challengers. A three-day champion retired undefeated and won a new car.
