I have created the following killer sudoku, I though it was easy until, Jsudoku said that the following techniques were needed.



Naked Single
Hidden Single
Single Innies & Outies
Unique Pair
Naked Pair
Hidden Pair
Unique Triplet
Odd Pairs
Odd Triplets
Double Innies & Outies
Mandatory Inclusion
Odd Quads
Complex Intersection
Triple Innies & Outies
Double Outies minus Innies
Complex Naked Pair
Complex Hidden Pair
Conflicting Pair
Quadruple Innies & Outies

Could somebody grade this puzzle and tell me what constitutes an easy, Medium, Hard and Extreme killer sudoku puzzle please?

Thank you in advance.

Hi Telkin,

If you think that it is easy then it is easy .... Don't let anyone convince you otherwise because difficulty is subjective.

SudokuSolver gives it 1.25 at the low end of the assassin range. That feels about right to me.

If you found it easy you should be doing the assassins: ... um.php?f=3
