TicTacToe9*9 play online

TicTacToe9*9 takes the classic game of Tic-Tac-Toe and adds a strategic layer to it.
Tic-tac-toe is terminally dull. Theres no room for creativity or insight. Good players always tie.

1.Each turn, you mark one of the small squares.
2.When you get three in a row on a small board, youve won that board.
3.To win the game, you need to win three small boards in a row.
4.You dont get to pick which of the nine boards to play on. Thats determined by your opponents previous move. Whichever square he picks, thats the board you must play in next.

What if my opponent sends me to a board thats already been won? In that case, congratulations you get to go anywhere you like, on any of the other boards. (This means you should avoid sending your opponent to an already-won board!)
