Here is another easy puzzle with 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.

V: Digits in cells joined by a V sum to 5. Not all 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.
