RULE SET:
Normal Sudoku rules apply. Place the digits 1 through 9 in each row, column, and box.
KROPKI: White dots are consecutive. ALL dots are given.
GERMAN WHISPER (GREEN): Adjacent digits on a green German Whispers line must differ by at least 5. Digits may repeat if other rules allow.
RENBAN (PURPLE): Digits on a purple Renban line must be a set of consecutive non-repeating digits, and may appear in any order.
REGION SUM (BLUE): digits on a blue region sum line have an equal sum N within each box it passes through. Region sum lines must cross box borders.
For our color blind friends:
The Region Sum line is the seven cell line staring in box 3 (R1C7 to R6C7).
The Renban line is the six cell line in the bottom of box 7 and ending in box 8 (R8C4).
All other lines are German Whisper.

Excellent puzzle! Lots of fun. I always love these kind of puzzles, where almost all the digits get filled in in the last 20 seconds of the solve. Thank you

Very nice! Felt more like a 2* when you understand what disambiguates the solution
