Solve with Sudokupad
After you have solved it, click here
here to see the picture without numbers.
Note: The parity lines (which alternate between odd and even) are red. There is only one palindrome line.
• Normal Sudoku rules apply.
• Digits along a red parity line must alternate between odd and even.
• Digits along the grey palindrome line read the same forwards or backwards.
• Adjacent digits along a green German whisper line must have a difference of at least 5.
• Digits along a dark orange Dutch line must have a difference of at least 4.
• Cells with a filled square must be even.
• A black dot between cells indicates cell values with a 2:1 ratio.
• A white dot between cells indicates cells with consecutive values.
• Not all dots are shown.
• A V between two cells means they add up to 5.
• An X between two cells means they add up to 10.
• The board is covered in fog. Place a digit correctly and the fog will lift around it.
Lösungscode: Enter digits in 3rd row.

It's a nice little puzzle. Not that hard, but still fun!

Very easy if you assume one palindrome line. Impossible otherwise.

Added note that there is only one palindrome line.

Initially, I didn't pay attention to the comments, so the only way I was able to proceed is to assume one palindrome line. After I solved the puzzle, I tried to find a way to proof logically that there can be only one palindrome line but I was not successful. So I assume it should be part of the rules unless I am missing something.

The "only one palindrome exist" should be included in the rules. Other than this a cool puzzle

Your rules are incomplete, the puzzle cannot be solved without reading the comments. Please update the puzzle rules. Apart from that, it's a nice puzzle.

Should have include that statement in edited post rather than in comment

I don't usually read the comments before starting a puzzle, so I got hopelessly stuck at one point. Eventually I looked again at the puzzle page and found the comment about the palindrome line. Is there a reason that that's not in the description?
Except for that, I enjoyed the puzzle.

There is only one palindrome line.
