Through my intense research, I've come to realize that Tic-Tac-Toe is really, really, REALLY, pointless.
In theory, there are only 362,880 (or 9 factorial) unique possible combinations of Tic-Tac-Toe games. In reality, the number is much smaller, being only 125,168 because of most games ending after a player gets three in a row.
125,168 different moves sound big on paper, but when compared to an actual game, this number is pathetically and laughably small. In comparison, there are over 121 million different possibilities after the third pair of moves (so 6 moves total) in chess.
Additionally, Tic-Tac-Toe is classified as a Zero-Sum Game. This means if your opponent knows what they're doing, you will never win and if you know what you're doing, you will never lose.
What this equates to is nobody ever wins at Tic-Tac-Toe unless they're genuinely careless and do random moves. This is why if you go to Google and play the bot on Impossible, you will always tie or lose.
