Indivisible
(Published on 9. August 2026, 22:32 by NotSoMagnifique)
You may have seen a recent puzzle from sujoyku and me where the concept of indivisible killer cages was introduced. What you may not know if you didn't see the testing channels on Discord is that I actually kicked off the indivisible rule set with the puzzle you see below - hope you like it!
----
Rules:
- Normal sudoku rules apply.
- Indivisible Renban - along a hollow purple line, digits form a consecutive set in some order. Additionally, no set of two digits in any combination on the line can divide evenly to a whole number. For example, a 3-length line containing the digits 2, 3, 4 would be invalid, but a 3-length line with the digits 3, 4, 5 would fulfill the rule.
- Ratio Kropki - two digits separated by a black Kropki dot have a ratio of 2:1. No negative constraint.----
Puzzle:
Solution code: Row 9 digits left to right

Very nice. I got focused on the indivisible sets and forgot they were also consecutive, which made it much simpler!

I like the rule set, enjoyed the puzzle, but before this becomes entrenched: can we find a different way to render the indivisible renban lines?
I found it very hard to read my center pencil marks. In fact it took me a few times scanning the puzzle to even figure out where my remaining marks were.
