Player soon discovers that best play from both parties leads to a draw(Often referred to as CAT or CAT's Game). Hence, TIC TAC TOE is most often played by Young Players.
Choose center if available, if not choose corner, you will loose if you do not follow this strategy! You should always choose a corner first b'coz mathematically it gives the opponent the least amount of options to avoid you winning.
If both players follow these rules and pay attention during the rest of the game, neither will win and neither will loose.(called a DRAW or CAT's game). However,
most don't pay attention and you will find opportunity to win.
BEST OF LUCK!
