Thank you and I apologize in advance for how few facts I can remember.
I'm looking for the title of a book. I think it may be the first in a series of perhaps 3 or more books. I read it around 1990 but got it from the library so it is likely older than that.
What I can remember is there is a man that travels from planet to planet and he has to figure out the problems / how that planet works to acquire the skills to move on to the next planet. I believe he was on one planet where he hops from stone to stone because the ground is toxic. I think (but can't remember) if he is trying to get back to Earth. Of course he is clever, resourceful and always somehow figures out the patterns.
If it helps I think it had an orange-ish cover, some sort of desolate landscape. Any help would be appreciated and I realize this may fit many narratives.
Finally I think I would probably categorize this as both sci-fi and fantasy.
