Dutch Sum Box
(Published on 26. March 2023, 01:56 by yttrio)
This is the second puzzle in a series exploring lines that act as both Dutch Whispers and region sum lines. Based on previous feedback, the difficulty is likely somewhere between 3 and 4 stars, so I'm listing it as 4 for now. The first puzzle in the series (which should serve as an easier introduction to this constraint combination) can be found here.
Rules:
Normal Sudoku rules apply.
All lines act as both Dutch Whispers lines and region sum lines.
Consecutive digits along Dutch Whispers lines must differ by at least 4.
Digits along a region sum line must add to the same total in each region the line enters.
Solution code: Row 3 followed by row 7 (18 digits no spaces)
