 Invitations to audition were awarded by postcard drawings and other types of contests.A 10-question pre-test was first devised when contestant coordinators conducted a two-week East Coast search at Merv Griffin's Resorts Atlantic City hotel and casino.In order to test as many people as possible, hopefuls were invited to take the screener pre-test as often as once per day, and those with a passing score of 7 were invited to return to take the 50-question full test.
