The Hollywood Squares is an American panel game show in which two contestants play tic-tac-toe to win cash and prizes. The show piloted on NBC in 1965, and the regular series debuted in 1966 on the same network. The board for the game is a 3 × 3 vertical stack of open-faced cubes, each occupied by a celebrity seated at a desk and facing the contestants. The stars are asked questions by the host, and the contestants judge the truth of their answers to gain squares in the right pattern to win the game. In 2013, TV Guide ranked it at No. 7 in its list of the 60 greatest game shows ever.
