How to Play
This is Ultimate Tic-Tac-Toe: a big 3×3 board where each of the 9 cells is its own small tic-tac-toe board. Win three small boards in a row to win the whole game.
The twist: whichever cell you play in sends your opponent to the matching small board for their next move. Play the top-right cell of a board, and your opponent must play somewhere in the top-right board next.
House rule for finished boards: if that board has already been won, the player who won it gets to pick which board their opponent must play in next. If it ended in a draw, the opponent is free to play anywhere.
A small board that ends in a draw counts for nobody - it just can't be used to complete a line on the big board.
If all nine boards are decided and nobody has three in a row: whoever won more boards overall takes the game. Still tied on boards won? Then it's a draw.
