Various game shows have been based on tic-tac-toe and its variants:{{cn|date=September 2020}}
* On ''[[Hollywood Squares]]'', nine celebrities filled the cells of the tic-tac-toe grid; players put symbols on the board by correctly agreeing or disagreeing with a celebrity's answer to a question. Variations of the show include ''[[Storybook Squares]]'' and ''[[Hip Hop Squares]]''. The British version was ''[[Celebrity Squares]]''. Australia had various versions under the names of ''Celebrity Squares'', ''[[Personality Squares]]'' and ''[[All-Star Squares|All Star Squares]]''.
* In ''[[Tic-Tac-Dough]]'', players put symbols up on the board by answering questions in various categories, which shuffle after both players have taken both turns.
* In ''[[Beat the Teacher]]'', contestants answer questions to win a turn to influence a tic-tac-toe grid.
* On ''[[The Price Is Right (franchise)|The Price Is Right]]'', several national variants feature a [[pricing game]] called "Secret X", in which players must guess prices of two small prizes to win Xs (in addition to one free X) to place on a blank board. They must place the Xs in position to guess the location of the titular "secret X" hidden in the center column of the board and form a tic-tac-toe line horizontally (across) or diagonally (no vertical lines allowed). There are no Os in this variant of the game.
* On ''[[Minute to Win It]]'', the game Ping Tac Toe has one contestant playing the game with nine water-filled glasses and white and orange ping-pong balls, trying to get three in a row of either color. They must alternate colors after each successful landing and must be careful not to block themself.
