My experience with using LLMs for things like MIT Mystery Hunt is touch and go.
On most of them I've tried it doesn't seem to do much, but I do now use them to try and get crossword clues where I know bits that are often too abstract for crossword solvers.
e.g. "a word that is six letters, is related to royalty, and has a state abbreviation in it" (this isn't a real clue, just an example of a clue that an LLM is much better suited than something like Nutrimatic or a crossword solver)
I would be curious to hear if / how others us LLMs for abstract riddles/puzzles like that though.
