What is Tic-tac-toe?
1.
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".
