Definition
Tit-tat-toe represents yet another spelling variation for the game more commonly known as tic-tac-toe or ticktacktoe. Despite the slightly different name, the game's essence remains the same: two players marking a 3x3 grid with 'X's and 'O's. The goal is to achieve three in a row—horizontally, vertically, or diagonally. Think of it as a historical predecessor. The game's history predates modern spellings.
