Nothing wrong with that. My idea was to do a vector (or fixed-size array if you prefer) in one dimension. An example would be something like [0, 1, 2, 0, 1, 0, 2, 0, 2] (where O is 1, X is 2 and 0 represents an empty cell). The math to get the index is similar to this:

Might be overkill for a simple tic-tac-toe game, but if you want to rotate the board or whatever, you can just change the math you do to get the index. I’m not at all a math expert, but it seems like a reasonable approach.

A simple vector seems fine. Each item in the vector is an enum representing cell state. You can translate x y coordinates to an index pretty easily.

House will just do both at once.

Counterpoint: it’s indispensable and nothing really fills the same niche.

IANAL but this seems stupid to try in court assuming the footage is under good chain of custody.
