I am happy to present another challenging entropic-polarity duo :-)
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.
Entropic: Any sequence of 3 adjacent digits along a peach line must have a low digit (123), a medium digit (456) and a high digit (789).
Entropic Line Explanation:
Basically, if one digit on the line is low, then every third digit will also be low; same applies for the remaining groups.
