A simple game using a small 3X3 graph of empty boxes. Players alternate turns by placing a single 'X' or 'O' into an empty box. The first player to get 3 X's or O's lined up horizontally, vertically, or diagonally, wins the game (a line is often drawn through the 3 winning icons). If each player is smart enough the game will always end in a draw, otherwise known as a "cat's-tail".
Guy 1: Dude, stop playin tic-tac-toe.
Guy 2: What are you talking about? I haven't played the game since I was 10?
Guy 1: Oh.......I got this 3X3 graph, wanna play?
Guy 2: I hate you.
