Tree in Autumn (Herbst) 秋天

(Published on 25. July 2023, 06:17 by Will Power)

Normal Sudoku rules apply. RENBAN LINES- Numbers on brown lines are each a set of non-repeating, consecutive numbers, in any order. ENTROPY LINES- Any 3 consecutive numbers on orange lines contain exactly one high (7,8,9), one middle (4,5,6) and one low (1,2,3) number. VIRTUAL ARROW SUMS- Numbers on red lines act like Sudoku arrows, where three of the numbers add to the fourth number on the line. The solver must determine which END OF THE LINE contains the sum. Numbers do not repeat on any lines. Numbers in cages sum to the number in the top left corner of the cage. Numbers with a black dot between them are in a ratio of 2:1. Not all possible dots are given.

Stumped after an easy first 15 digits - fiendishly difficult now
EDIT - of course 2 minutes after posting this I figure it out...
