Chaos Construction: Region Sums

(Eingestellt am 7. April 2022, 20:42 Uhr von KNT)

Place the numbers from 1 to 9 exactly once in every row, column, and region. One number is already given. Each region is orthogonally connected and must be located by the solver.

Region borders divide the blue lines into segments with the same sum. Every line must visit at least two regions. In the bottom two rows, there is an instance of two lines crossing; these are different lines. A number in a colored cell indicates the total count of numbers on the segment of the blue line within that region.

A black circle indicates that it is possible to form a consecutive sequence using the four touching numbers.

Thanks KNT, I certainly did enjoy it. I wonder if you had as much fun setting it as I did solving it. We shall probably never know ...

Very nice use of the region sum lines gere ! The geometry at the bottom is just amazing, and I loved how the big line helped to define regions so precisely in the mid solve.

Great construction! For me the first half was very smooth, and then I spent forever on the ending, which I found very intricate, although in the end rewarding.

very nice puzzle. thanks.
Logical path was very clear, at least for the first half of the solve :-)

Another great puzzle as always! Though to be honest this one is harder than all of your other CC puzzles with the break-in kinda tedious for me (at least)

---

I'm glad you're enjoying these! You think it was tedious though? Maybe it's possible to "grind" through the start with trial and error, but I think there's a very elegant way to do every part of this puzzle. Do you mind mentioning more details in a hidden comment? I can explain my thought process there.

That was a fun puzzle. I loved the break in.

Clarified rules.

Is there a diamond hidden behind the two crossing lines at the center bottom of the grid? There seems to be a diamond there.
Also, I'm assuming the crossing lines are two different lines. Is that correct? Or is it a single branching line?

------

The CTC link should make it clear, but yes there is a diamond behind the intersection of the cross. And I will update the rules to say where lines intersect, they cross. There are no branching lines. Sorry for the confusion.
