Play in Sudokupad
Normal sudoku rules apply.
Parity lines: Digits on a red line alternate parity (odd/even).
Red lines are also product arrows. The product of the digits on a red arrow outside the cage (multiply all digits) equals the two digit number on the red line inside the cage (read left to right or top to bottom).
Digits in a cage sum to the total given.
Lösungscode: Column 1 top to bottom

Just after finishing I realized that I might have used the parity of the line. Works also without it. I love novel ideas like this.

Very clever! The parity line rule did make some things about it very easy, though I'm not complaining. Always nice to flex my factoring skills.
It does make me wonder after a variant where the arrows *aren't* parity, though...
Not entirely sure why this is voted 2*. Great puzzle, but not that hard.

Very cool, but I totally forgot the parity rule, still solved but required a bit of math. Thanks!

Very nice! I didn't need to use the parity constraint tho.
