Four body problem
(Published on 21. November 2021, 18:11 by filuta)
Normal sudoku rules apply. In addition to that:
-the indicated diagonal contains all digits from 1 to 9,
-cells that are a (1,3)-jump away cannot contain the same digit,
-clues outside the grid indicate the sum along the corresponding diagonal,
-gray lines are palindromes (i.e. read the same from both directions - like 147741),
-circles mean odd digit, squares mean even digit.
A (1,3)-jump is a move like a chess knight, but first jump by 1 in some direction and then jump by 3 in an orthogonal direction. In the example below, 7 in r4c4 means that none of the purple cells can contain 7.
Big thanks to Piatato for his test solve and feedback.
Have fun with the puzzle, I'll be happy to read your comments.

Funny coloring puzzle. High 3 stars, I'd say. Certainly can be bumped to 4 stars considering anticamel is a fairly uncommon ruleset

Phew! This one looked so beautiful, so I had to work on it ... . Especially the first half was exhausting till the diagonals came into play. But then all went smoothly and fast. Great job!

Cool logic, though very hard. 5/5 difficulty for me.

Thank you!

Oh boy, that wasn't easy. I failed and bifurcated. :-(

What a beautiful construction this is, both puzzle-wise and esthetically! :-)
Some nice logic until it finally solves..

Thanks a lot for such a nice comment (and the solve too).

Cool puzzle, with the 1,3 rule really coming into play and leading to some very nice logic. :-)
