Normal sudoku rules apply.
German whisper: Adjacent digits along a green line have a difference of at least 5.
Odd/Even: Along a single line, digits must be all odd or all even.
X/V: Digits in cells joined by an X sum to 10. Digits in cells joined by a V sum to 5. Not all Xs and Vs are necessarily given.

Pro tip: reading the rules helps a lot. I was wondering how in the world this was a 1 star until I noticed I missed the odd/even
