Hello. This time I have a simple puzzle with the negative Kropki constraint.
Have a good time solving!
Solve on SudokuPad
Normal sudoku: Every row, column and 3x3 box must have all numbers from 1 to 9 exactly once.
Palindrome line: Digits appear along a gray line in the same order when read forward or backwards.
Kropki dots: A white dot between two cells indicates that the neighbouring digits are consecutive. A black dot between two cells indicates that one of the digits is twice as big as the other digit.
ALL possible dots are given.
Solution code: Row 9, 9 digits left to right.

I didn't use the palindrome or the negative constraint. Despite that, the puzzle is almost solvable, and I could get the solution code as well.

i used the palindrome, but not the negative constraint.
negative constraint is "hard" to keep track of, because it has no visual indicators, so i generally ignore it.

I did not use the palindrome line, it's not necessary, overall a good puzzle
