Entropy and Whispers (Sudoku29)
(Published on 16. June 2022, 14:34 by Sumanta(ANU))
===Rules===
Normal Sudoku rules apply.
Entropy: Consider the low digits (1, 2, 3), middle digits (4, 5, 6) and high digits (7, 8, 9) as three different groups. Each 2x2 box in the grid has to contain at least one digit of each group.
X/V: Cells separated by X sum to 10. Cells separated by V sum to 5. All possible V’s are given. All possible X’s are NOT given.
Red lines: Adjacent digits differ at least by 6 or more.(whispers6)
Green lines: Adjacent digits differ at least by 5 or more.(whispers5)
===Notes===
Negative constraint is only on V and NOT on X. There are two different types of Whispers lines. The V in box 5 separets two different red lines.

@chelo, Thanks a lot for the solve and feedback. I am happy that you enjoyed the puzzle.
You can always use other softwares if it's easier there. I don't have the sudoku-pad at present, but I have plans to have it in future. For coloring puzzle it's best with multiple features. Thanks:)

I've tried lots of times before succeeding, the puzzle is apparently easy but it is very risky to make some mistakes. I have converted the link to CTC because the solving is easier with the multiple colouring feature.
Thank you @Sumanta(ANU) for setting and sharing, it was lots of fun!..

There was a issue with the uniqueness of the previous version of the puzzle as pointed by some solvers. Its resolved now. Not much change except the extension of one Whispers line to R4C5. Happy solving!!
