ON EDGE: Yellow & Lavender
(Published on 26. February 2025, 02:19 by marty_sears)
RULES (for part A):
- Normal 6x6 sudoku rules apply.
- Each spot along a coloured edgeline has a value, found by performing a calculation using the two digits it sits between:
- Sum (+) spots: The value of a spot with a plus sign equals the sum of the two digits it sits between.
- Difference (-) spots: The value of a spot with a minus sign equals the larger digit minus the smaller digit.
- Product (x) spots: The value of a spot with a multiplication sign equals the product of the two digits.
- Ratio ( / ) spots: The value of a spot with a forward slash equals the larger digit divided by the smaller digit. (The value will always be an exact integer.)
- Yellow lines are 'edge nabners'. No two spot values anywhere on the same edge nabner may be equal or consecutive.

That 9x9 had me rewiring my math neurons, but when I found that first break-in, I couldn't look away! What a fun journey and beautifully built!

After Brown & Green, as well as Blue & Pink… this was much more challenging! The final 9x9 was so difficult in the first 3rd… I could not wrap my head around the logic, nor how to mark it. This whole series was very cool, and I do love the edgeline mechanic!

Brilliant!
A really nice flow and never any chance to be complacent. Very satisfying when it all works out.
I think the yellow training grid is almost as difficult as the 9x9!

Thank you for this awesome edition, Marty! I love "normal" Nabner and Zipper lines, and their edge relatives were no less fun. Admittedly, I needed some help for the 9x9. But after the nudge, it all flowed incredibly well. Thank you very much for setting and sharing these gems!

Loved it. I think this is my favorite in the series so far, because of how it all fit together. Thanks for another great one!
