This time diagonal was introduced to Erica series :-)
I hope you will enjoy and I would be really grateful for all the comments and ratings.
Normal sudoku rules apply.
German whisper: Neighbouring/adjacent digits along a green line have a difference of at least 5.
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 given.
Diagonal: Digits along the marked blue diagonal must not repeat.
If you liked this puzzle, I recommend trying out my other puzzles: The Erica Series:Lösungscode: First (1st) column of the grid from top to bottom.

Odd, I found figuring out the polarity the easy part

Excellent puzzle. Once you figure out the polarity of the German Whisper line, it's manageable to solve. Thanks for the puzzle.

Not sure if I concur with VitP'S assessment, but I'd say figuring out polarity and one other step is probably 2 stars, the rest only one. I tend to veer to the harder rating since people looking for a real one star might have a problem.
