Normal Sudoku rules apply.
For accessibility, lines have been marked with an abbreviation to distinguish them as an alternative to the line's colour.
Cells connected by a pink Renban [RN] line form a set of consecutive digits, in any order, without repeats.
Adjacent digits along a green German Whisper [GW] line must differ by at least 5.
Adjacent digits along an orange Dutch Whisper [DW] line must differ by at least 4.
Box borders divide a blue Region Sum [RS] line into segments with the same sum.
Digits in cells joined by an X sum to 10. Digits in cells joined by a V sum to 5.
Digits in cells joined by a white dot are consecutive.
Not all Xs, Vs or dots are necessarily given.

Well, I for one did use all of the constraints. Happy Christmas. ;)

Nice snack but I was a little bit surprised that the region sum line was not needed for the whole puzzle

Nice puzzle pagedo! Thanks for sharing. I just wanted to mention that not all of the constraints seem to be required to solve the puzzle (unless this was intentional, which in all cases I don't mind as I have done the same myself before, but I thought I would let you know).

I really enjoyed this one. Occasionally a deduction would sneak up on me that I wasn’t expecting and I didn’t remember encountering a similar pattern with other puzzles.
