That’s what I’m doing.

Hi, Thanks for this great puzzle. My code quickly solves all the test cases, but fails at the “super easy” validator after submission. I checked my code but did not find the issue. How could I get some insight on this failing case ?

#44

There isn’t any validator named “super easy”.

#45

My mistake, should be “Very Easy”

#46

I finally found my mistake thanks to the 2x2 sudoku solver. When adding the input numbers to my sudoku, one of these numbers had already been deduced using the previous numbers. Apparently this situation only appeared in the “Very Easy” validator.
