Tic Tac Toe (also called Noughts and crosses, Xs and Os, XOX Game, 3 in a row) is a very popular children’s pencil and paper board game, which is often played and enjoyed by many adults, as well. Because of its simplicity, this 3 row per 3 row board game may seem trivial at first, however, Tic Tac Toe involves its share of analytics and rapidity. The game is a lot of fun for players of all ages and provides one with a great brain workout too!
