 Nine celebrities, seated in a three-by-three tier as in a tic-tac-toe board, joined two contestants one of them a champion in a game known best for the celebrities  witty answers to questions. The object was to win an otherwise standard game of tic-tac-toe by determining whether a celebrity was giving a correct answer to a general knowledge question or bluffing ("agree" or "disagree"). Contestants selected a celebrity, for which host Marshall read a question; a correct decision to agree or disagree by the player allowed him/her to place their mark in that box, while the opponent s mark was placed there if said decision was incorrect (unless it led to tic-tac-toe, in which case the contestant had to earn the box). During the first complete game of a show, a "Secret Square" game offered the contestants a bonus prize package for a correct answer. The contestant winning the best-of-three match was champion and returned to face a new challenger. Five-time champions retired un-defeated with a $2,000 bonus and a prize package (containing such things as cars, trips, furs, jewelry and furniture). In later years, daily winners were allowed to select a celebrity, and won a bonus prize concealed inside an envelope.
