Hex: A Hexagonal Chaos Construction
(Published on 7. June 2022, 05:19 by mathpesto)
Rules:
Place the digits 1–9 in the grid so that no digit repeats along the horizontal axis, the two diagonals, nor within a region. A region is a collection of nine connected cells. Regions do not overlap and are to be determined. One boundary between regions is given.
A white dot connects adjacent digits that are consecutive and in the same region. A black dot connects adjacent digits that are in a 1:2 ratio and in separate regions. All possible dots are given. (Adjacent cells can have consecutive digits without a white dot between them, so long as they’re in separate regions. Adjacent cells can be in a 1:2 ratio without a black dot, so long as they’re in the same region.)
Puzzle:
Example:
The digit in the red hex cannot be repeated on any of the red lines. Same goes for the green hex and the green lines.
Solution code: Type the digits (no spaces) of the region containing R7C3 as follows: The digits of the region's topmost row (left to right), the digits of the region's second row (left to right), etc.

Interesting variant to spice things up a little. I got stuck at one point and then realised a different tack was the way to go.

Spent far too long scratching my head at the end, there's always some subtle rule I forget about. Really love this hex style, thought I would try this one out after seeing Zetamath solving your other one on stream. Many thanks, lovely puzzle!

while not a hard puzzle, it took a while to wrap my head around how the hex-grid worked

That was fun. It was easier than I expected. I gave it 3 stars out of 5 for difficulty.

By horizontal axis, do you mean each row?

@wildbush7 that's correct!

@robals: What's wrong with this? It is the solution.

Fun puzzle, took a bit to get started but everything resolves very nicely.

Very nice. Not too hard, but always challenging.
