Tic-Tac-Dough

Tic-Tac-Dough is an American television game show. It is based on the paper-and-pencil game of tic-tac-toe. Contestants answer questions in various categories to put up their respective symbol, X or O, on the board. Three versions were produced: the initial 1956–59 run on NBC, a 1978–86 run initially on CBS and then in syndication, a syndicated run in 1990, and returned back in 2025.
