Chatgpt keeps cheating at hangman and 20 questions

Tried playing hangman with it. It changes the word partway through, and once said a letter wasn't in it when it was. Is this a known weakness? Any way to set up word games so it plays fair?

It isn't cheating on purpose, it just has nowhere to keep a secret. Each reply is generated from the visible chat, so there's no hidden word sitting anywhere - the answer isn't fixed until it gets written down. That's why it drifts to fit your guesses. Works much better the other way round: you think of the word, it guesses. Or make it write the word at the start in a form you won't read, so it's locked in.
