RULE SET:

Normal Sudoku rules apply. Place the digits 1 through 9 in each row, column, and box.

GERMAN WHISPER (GREEN): Adjacent digits along a green German Whispers line must differ by at least 5. Digits may repeat if other rules allow.

RENBAN (PURPLE): Digits along a purple Renban line must be a set of consecutive non-repeating digits, and may appear in any order.

X-pairs. Cells separated by a "X" must sum to 10. Not all X-pairs are given.

For our color blind friends:
German Whisper lines are thick and Renban lines are thin.
