Stream Crossing
(Eingestellt am 20. April 2022, 12:34 Uhr von Jreg)
The rules are as follows:
Normal Sudoku rules apply.
There are two streams which may cross and uncross at any point.
One of them is the given grey line. Digits along the grey line form a palindromatic sequence, which means it reads the same from either end. The palindrome goes through every number 5 that is in the grid.
The second stream must be deduced: it is formed entirely by orthogonally connected odd digits, and it connects the four corner digits in the grid. Not all odd digits must necessarily be contained within this stream.
Furthermore, the digits marked with a small square are NOT orthogonally adjacent to any digit of the same parity, and all such squares are given.

Lösungscode: The seven digits in column 6 which lie on the palindrome, read from top.

As another solver said, you may want to specify that the second stream can branch. Given that the first stream is a single long line, it is not obvious at first glance that this is the case.
I'd also put the difficulty higher than 1 star, if for no other reason than very long palindromes are hard to keep track of.

Lovely puzzle, I love how it flows through the solve. I am biased towards palindrome puzzles lol so it was great fun, and congratulations on your first publish!
As a small aside, I'd clarify in the rules that the second stream can branch - it didn't hinder my solve but just to make it super clear.
(Btw not sure if your name references it but I'm a fan of Jreg also! I wouldn't have expected to find someone else here with those two kinda niche interests overlapping haha)

I can't do HTML so the reupload is caused by initial coding mistakes.
