Ultimate Tic-Tac-Toe

Overview

Ultimate Tic-Tac-Toe is a new spin on the old Tic-Tac-Toe game. In Ultimate Tic-Tac-Toe, each square in the 3×3 grid contains a smaller Tic-Tac-Toe board. In order to put your X in a square on the Ultimate Tic-Tac-Toe grid, you must win the mini-board that square contains.

But there is an additional complication: You don’t get to pick which board in the 3×3 grid you get to play on. That is determined by your opponent’s previous move. Whichever square he played on, that is the board you must play on when it’s your turn. For example, if your opponent chooses the bottom right square, then you must play on the bottom right board. If you then choose the top middle square on that board, your opponent must then play on the top middle board. And so on.

If the next board to be played has already been won or tied, then the player can choose any board to play next.
