Normal Sudoku rules apply. Each row, column and 3x3 box contains each number from 1 to 9 exactly once.
German Whisper Sudoku rules apply. Two cells connected by a grey line must have a difference of five or more between their digits.
Note: The cross shape in box 3 contains two separate straight German whisper lines (R1C8-R2C9 and R3C7-R2C8-R1C9), which do not affect each other.
The puzzle is also available online.
Solution code: Row 4 and column 9

Description here says the lines are palindromes. The description in the f-puzzles link says it is a German Whisper ruleset. Please clarify.

Are the gray line segments in cages 3 and 7 also palindrome? Did not see any killer dotted cage, please confirm the rules and pictures, thank you!
