Irregular sudoku rules apply. Place the digits 1-6 once each in every row, column, and irregular region.
German whispers: digits along a green line must differ from their neighbours by at least 5.
Region sum (blue) lines: box borders divide each blue line into segments. All segments on the same line have the same sum; different lines may have different sums.
Palindrome: digits along a grey line read the same forwards and backwards.
Parity line: adjacent digits along a red line alternate between odd and even.
Solve in VariantDoku (iOS, macOS, Android) or on SudokuPad.
Solution code: Enter the digits of column 6.

Excellent, took me 16 minutes of colouring and less than a minute of filling in the digits which felt magical.
