Is it me or this puzzle or this puzzle is not rated correctly?

Pappocom rates it as very hard and it is rated as fiendish on

sudokuoftheday.com

I solved it in less than 5! well actually it was more like 3'28 on Simple Sodoku. No Hint, no invalid moves.

There were a couple naked triples at most, but I don`t think naked subsets make a puzzle hard. Or should I seek harder puzzles.

Naked subsets are easy to spot so I dont think this could make a puzzle rated at very hard, dont you think.

Tell me what you think and your times!

I agree with you - nothing difficult about this one. Sadman Sudoku rates it as hard but I'd done it in less than 5 minutes.

Is this three-and-a-half minutes with candidate listing on, or off? Because with no lists, that's highly impressive.

Sorry, should have mentionned, it was with candidate listing on, shame on me.

[PaulIQ164]

It's still a very good time, of course.
