There are 5 duplicates in this set of 33, and they all have the same rating: 9.2/1.2/1.2. Curious.

these 33 sudoku have been selected from a list of 1200000 sudoku which is the result of multiple generations with different seeds (it can explain the occurences) with my maplet (my own algorithm)
For the rating I used the excellent program by "1 to 9 only" : PGExplainer.
These sudoku are those which have the maximum difficulty of my 1200000 list (9.2)
