Television shows based on tic-tac-toe

Tic-Tac-Dough is an American television game show based on the paper-and-pencil game of tic-tac-toe. Contestants answer trivia questions to put up their respective symbol, X or O, on a tic-tac-toe board. Four versions were produced: the initial 1956–1959 run on NBC, a 1978–1986 run initially on CBS and then in first-run syndication, a syndicated run in 1990, and a 2025 revival on Game Show Network. The show was produced by Barry & Enright Productions. However, the rights to the format are controlled by NBCUniversal.
