It must be computer generated. But some are cleverer than others (and make more money at it – eg the guy in The Daily Telegraph). Is it simply the reverse of solving a sudoku, encoded? (Fiendish is no problem with logic.) Or is it more sophisticated than that?

the medium and easy ones, but i am always relying on an educated guess to complete the hardest ones, and its 50/50 whether i get them right or not.
what is the last piece of the jigsaw i’m not getting strategy-wise, that will enable me to complete all sudoku even the hardest ones?

OK, so from wherever you might be solving Sudoku, I am sure they tell you the level, like easy, medium and hard. So, I just solved an easy Sudoku puzzle and it took me 9 minutes. Is the time I took normal? Or, do easy Sudoku puzzles require even less time than what I used?

P.S. – I am a very new Sudoku player
P.P.S. – I put this question in this category because there was no other category which seemed suitable to me for this question. Moreover, I think Maths people would be playing Sudoku.

easiest method to solve sudoku puzzle

anything i can do randomly would help. that side of my brain is dormant. Im more of a writing person, but enjoy the challenge of math. Oh yeah something challenging would be cool and something like a routine which i can do on a daily basis or as long as i want.
