Ultimate Tic Tac Toe

How to Play:

Ultimate TicTacToe can be considered as a two-level Tic-Tac-Toe or recursive Tic-Tac-Toe. Each field contains a small Tic-Tac-Toe board yielding a 9x9 board.

In order to win the game, you have to win three inner boards in a row.

You may only play in the small board that corresponds to the last field your opponent played. When you are sent to a small board that is already decided, you can choose freely.
