tic-tac-toe also tick-tack-toe or tick·tack·toe 
(tĭk′tăk′tō)
(tĭk′tăk′tō)n.
A game played by two people, each trying to make a line of three X's or three O's in a boxlike figure with nine spaces.
[Probably imitative of the sounds of the original children's game, in which players brought pencils down on a numbered slate with their eyes shut.]
