The Great Divide

(Eingestellt am 8. August 2026, 14:04 Uhr von marty_sears)

A 2nd puzzle featuring the 'Isofill' format that I introduced in 'Homogeneous', this time in collaboration with the legend sujoyku,.

    Rules:

    ISOFILL: Divide the grid into 10 regions, each with 10 orthogonally connected cells. Every cell in a region should contain the same digit. All of the digits 0-9 must appear in the grid.

    NABNERS: No two digits on a yellow line may be the same or consecutive.

    ZIPPERS: The two digits at either end of a lavender line sum to the digit on the central spot.

Lösungscode: Row 1 from left to right

I feel like a total buzzkill for giving this just nice, but I just think this ruleset would work better on an 8x8 grid. There was just quite a bit of counting how far each number could reach.

Now with that out of my system, this was really fun ruleset and I did quite enjoy the puzzle. I'd go with 3*, but as Marty said it's just LMD being LMD.

Thanks for setting these up Marty!

Wonderful puzzle as always. But I'm with the other commenters here, I'm baffled by the 2* rating, I'd easily give this a 3 or a 4, whereas the previous puzzle was easily a 2* instead of the 3* that it got.

Marty: I am also baffled by the 2* rating, but that's LMD for you :D

Wow. Found the break-in fairly quickly, but still found this a very tough solve. 4* for me. Loved it though.

Whew...
Who gave this 2 stars?? 4 stars for me, closer to 5 than to 3.
I got all (I think) the major deductions pretty quickly, but still, no break-in, there seemed to be many possible ways to fulfil the requirements.
After sleeping over it, I gave it another try. I finally found something I was pretty sure about (and later found a much easier way to prove that). After that, I gradually chipped away until it was done.
Beautiful puzzle, though!
Edit: after a re-solve, I realize that it _was_ a pretty obvious thing that I missed. If I had spotted that, I could have been halfway in no time. 3 stars for me now.

Wonderful! I found it much easier after seeing Simons recent video on the other one. I thought there were some interchangeable digits after the first two thirds of the puzzle, and had to stare at it for a good ten minutes before it clicked! Other than that it was a steady march.

Nice twist, I found it slightly harder than a 2* but that might be since I wasn’t familiar with the concept.

Fabulous! Easier than the last isofill, perhaps because of what I learned doing that one.

The interactions between the isofill and the nabners are so powerful! Gave it 2*, I found it significantly easier than the previous one

This was a great puzzle. I found it to be more of a 3 star puzzle. Thanks for setting!

Hmm, I wonder how long it will be before Simon solves this one…?! :P

Brilliant! Having never done a puzzle like this, I found it significantly harder than a typical 2*

More like these, please! Thanks :)

Thank you both very much for creating and sharing another lovely puzzle featuring this funny new ruleset. Wonderful stuff!

Very fun and approachable, thanks!

Interesting puzzle, the isofill mechanic requires some different thinking, but the puzzle is quite approachable once you get your thinking straight.

Thank you for introducing this new variant and the fun collab, Marty!
