I've tried tic-tac-toe with it (GPT4, web platform - maybe results are different with the API and temp 0?) easily a dozen times using various ways to prompt it over the past few weeks, it only played well once so I'm assuming it was just luck. I usually have it go first and start with X but have tried O. It usually makes no attempts to block 3 in a row, even if I tell it "try to win," "block me from winning," etc. Once it told me I won without having 3 in a row, many times it plays after I've already won and then tells me I've won, though usually it does manage to recognize a win condition. Today I tried asking it "do you know the optimal strategy?" and it explained it but claimed that it hadn't been using it to make the game "more fun for me" (honorable but I'd already told it to try to win) and asked if I wanted it to play optimally. It tried and ended up claiming we had a draw because neither of us achieved a win condition even though I'd won and it just played after the game was over. Various strategies include asking it to draw ASCII, provide moves in symbol-location notation, ex: X5, asking it how to play, telling it to try to win, etc. I do find it very odd that it is so poor at tic-tac-toe, it seems to even handle seemingly novel games better.
