Does anyone know of a puzzle which only requires naked singles and hidden singles but is still very difficult, i would be interested to know

There was a fiendish in The Times a few days ago that could be done entirely with hidden singles. I didn't study it in-depth, but there must have been something to it to warrant a label of Fiendish (Pappocom Hard) I suppose. Presumably there was only a small number of moves that could be made at each point in the puzzle.

I have analised that puzzle and i did notice that it was noticably harder than a "Difficult". I wondered if there was a super hard one with only a couple of possible moves at each point
