Dutch Flat Mates: Equal Split Lines
(Published on 22. October 2025, 07:00 by sujoyku)
I am thanking NEWS, Calvinball, DubiousMobius and LMDemasi for testing and wish you joyful solving!
Rules:
1) Normal sudoku rules apply, place the digits 1-9 so that they do not repeat in any row, column, or 3x3 box.
2) Dutch Flats: Every 5 in the grid must have a '1' directly above it or a '9' directly below it. It may have both, but it doesn't need both.
3) Equal Split Lines: Dots split blue lines into segments with equal sums. Digits may not repeat inside a segment. Different lines may have different sums.
Here you can solve the puzzle online:
Solution code: Column 9 from top to bottom (9 digits in total)

Fun puzzle overall, but I missed something during the break in which made things very convoluted. I was able to figure out what I missed by trying the break in again after finishing, which made it a lot more elegant so thats on me.

Thank you for your comment, Norkas! The break-in probably is one of the hardest steps in this one. I am glad that you had a fun solve.
