I have been wondering about if there is a synonym for a person who gives clues but does not give away the real answer. These keywords are too extensive for any thesaurus. Can anyone find a synonym for this definition?
Sometimes that activity is called spoonfeeding. In that context, you might use the term "spoonfeeder".
To be more specific, I'm referring to game developers who operate ARG's, which are heavily based on spoonfeeding clues to game players. In some circumstances, they hide these clues, but I refer to that as hiding the spoon, instead of coming up with a new term for it. While it might not be in wide use, it certainly conveys the meaning and does so concisely.
