Logic Masters Deutschland e.V.

This is basically the child of my puzzles "Lovely Runes" and "Roundabout"! Thanks to sujoyku for testing and for the name.

Rules:

- Normal Sudoku rules apply.

- German Whispers - digits along a green German Whisper line must differ in value from their neighbors on the line by at least 5.

- XV sums - digits separated by X sum to 10; digits separated by a V sum to 5. No negative constraint.

- Kropki dots - digits separated by a black Kropki dot have a value ratio of 1:2; digits separated by a white Kropki dot have a difference in value of 1. No negative constraint.

- Palindrome - digits along a thin gray palindrome line read the same backwards and forwards.
