Using matrices to store board, a $3\times 3$ board $A$ can be converted to a number by computing $$\begin{bmatrix}1000000 & 1000 & 1\end{bmatrix} A \begin{bmatrix}100 \\ 10 \\ 1\end{bmatrix}.$$ (This simply concatenates the entries of $A$ as digits, which saves all the information you need assuming that each entry is either $0$, $1$, or $2$. Player 1: Computer. }`NErc +D/Z`IT?ri/dQ\Jr +Jkfjw-a d Since I am not good at combinatorics, I thouggt I would ask here: How many unique gameboards are there in tic-tac-toe which contain 1, 3, 5, or 7 moves and no winning pattern? It is not optimized, but gets you what you need. Below is a proof of concept in Python, but first the output of time when run on the process sending output to /dev/null to show how fast it is: As one commenter has pointed out, there is one more restriction. Let $B$ be the matrix $$B = \begin{bmatrix}0 & 0 & 1 \\ 0 & 1 & 0 \\ 1 & 0 & 0\end{bmatrix}.$$ Then the eight rotations and reflections of $A$ can be computed (easily, in TI-Basic) as $A$, $A^{\mathsf T}$, $BA$, $BA^{\mathsf T}$, $AB$, $A^{\mathsf T}B$, $BAB$, $BA^{\mathsf T}B$. (You'll have to do some work to take the move we obtain this way and rotate it back to the original board, but it is worth it.). Card trick: guessing the suit if you see the remaining three cards (important is that you can't move or turn the cards). Boards with 1 non-winning move: ${9 \choose 1} = 9$, Boards with 3 non-winning moves: ${9 \choose 2} {7 \choose 1} = 252$, Boards with 5 non-winning moves: ${9 \choose 3} {6 \choose 2} - 8 {6 \choose 2} = 1140$, Boards with 7 non-winning moves: ${9 \choose 4} {5 \choose 3} - 8 {6 \choose 1} {5 \choose 3} - 2 {6 \choose 4} - 6 {3 \choose 2} {3 \choose 2} = 696$. If there is a sequence of K neighbors, separated by a constant displacement vector, then these K points are "in-a-line".
