Normal sudoku rules apply (Digits 1-9 in each row, column, box without repeats).
Digits separated by red Kropki dots are coprime. That is, their greatest common factor is 1. 1 is coprime with all integers.
If two digits, x and y, are separated by blue Kropki dots, then y = 3x + 1.
No negative constraint.
Lösungscode: Row 7, from left to right

It's a really cool rule set, but there were many redundant red pairs

Minor clarification: There isn't any negative constraint
