Certain kinds of questions were "off-limits", such as name, age, occupation, and income.
When the original format returned to the syndicated revival in 1997, these rules were readopted but there was more of a variety between bachelors and bachelorettes.
Typically, a bachelorette would question three bachelors, who were hidden from her view; at the end of the questioning period, she would choose one to go out with on a date paid for by the show.
Occasionally, the roles would be reversed with a man questioning three ladies; other times, a celebrity would question three players for a date for themselves or for a co-worker or a relative of theirs.
Before becoming famous, Farrah Fawcett, Suzanne Somers, Yvonne Craig, Lindsay Wagner, Leif Garrett, Tom Selleck and Lee Majors appeared as contestants on the show in the 1960s and early 1970s.
