Super Tic Tac Toe

1. X goes first and can play anywhere.
2. The cell you pick sends your opponent to the matching board. Play the top-right cell of any board, and your opponent has to play in the top-right board.
3. Get three in a row on a small board to win that square of the big board. A small board that fills up with no winner counts for nobody.
4. Get three big squares in a row to win the game.

Dead Square

A won board stays open. If you're sent there, you still have to play there, even though the moves can't change who owns it. You only get to play anywhere when the board you're sent to is completely full.

Free Square

A won board is closed. If you're sent to a won or full board, you can play any open cell on any board that hasn't been decided yet.
