In the instruction book, I would personally interpret the arrows in the Heterocut example to point from a larger region to a smaller region, while the rules state that "Arrows always point from a smaller to a larger region."

I'm not sure if that's in issue with me, or with the instruction book/example.

I was about to protest the notation for Heterocut, to point out that the arrows look a lot like "greater than" symbols in eg Futoshiki, and that it would be much more logical to have them point from larger regions to smaller ones, rather than from smaller ones to larger ones.
And then I found that the IB also got it wrong, suggesting that the proposed notation is so confusing that even the author may have had trouble sticking with it.

Since the IB will need revision about this: may I suggest that the IB example's notation is much better than the IB text's proposal, and that it would be even better if instead of arrows one had "greater than" symbols?

Also, still on Heterocut, unless I am mistaken the IB example (with notation of the example rather than of the text) seems to have multiple solutions. The I and L tetraminoes at the top can be replaced by L (at top-left) and O (at top-right), while replacing the trimino-domino-O tetromino in the bottom two rows by I tetramino at bottom-left corner, domino horizontally on top of it, L trimino in bottom right corner.

Yeah, you are totally right, the notation used in puzzle and in rules differs. The correct one is used in puzzle, so the rules will be changed to "Greater than symbols always point from a larger to a smaller region."

And yes, there is mistake in the puzzle, it has multiple solution. The example will be fixed.

For the slitherlink regions, do the colored cells have to be inside a loop? Or is it possible to have the region be an outside area?

The colored cells have to be inside a loop.

Thanks a lot for the clarification! I must say I'm pretty excited about the concept of this round -- the IB example was already a lot of fun to solve! Though I will probably do badly, I tend to panic in rounds with heavily linked multiple puzzles, and region division puzzles aren't my strong suit.

This looks super fun, really enjoyed the example.

Question about the booklet: I imagine A3 would be a single page while A4 splits the puzzle across two pages at a similar resolution?

Also some formatting wishes (it will work fine as is, but if you happen to address this, lovely):
- the grid lines are very thick/opaque, making it hard to recognize a wall drawn over it; thinner dashing would be great
- I can make out the difference between blue and red on a grayscale print-out, but they're pretty close; I think if blue were made a bit lighter it would still be recognizable easily and the difference would be more clear

A3 is single page and A4 is 5 pages with same resolution of puzzles (2 puzzles for 1 page)

About thick lines, do you mean boundary lines? Because all other lines inside puzzle are dashed for that reason. I print it several times with different resolution, and everytime the lines was good. The coloring was my issue from the beggining, if use, and in what form,
but I should stick with this version. The actual puzzle will look pretty "similar" so, I belive, that it will be clear.

No, I meant the dashed lines. They're quite dark and thick compared to usual puzzle renderings, so I find myself having to work my pencil hard to see a clear difference between "unused line" and "used line".

(I zoomed in on the booklet earlier and now understand a bit better for why they look the way they do. That's a very creative solution for making dashed lines :p, and I understand how it's difficult to change.)

Anyway, as I said I'll manage, and I promise I'll stop bugging you about that now. :p
