Duplication
(Published on 28. July 2023, 00:00 by Xenonetix)
• Normal Sudoku & Yin-Yang rules apply.
• Unshaded cells are doubled for all arrow clues.
• Digits along arrow lines sum to the corresponding circled value.
• Yin-Yang: Shade some cells, so these conditions are all fulfilled:
◦ ◦ All shaded cells are orthogonally connected.
◦ ◦ All unshaded cells are orthogonally connected.
◦ ◦ No 2x2 area is fully shaded or fully unshaded.
Here's an example puzzle to demonstate the rules:
Hope you enjoy the puzzle! 😄 - Any feedback or comments welcome!
Solution code: Row 2 (left to right) with dashes when switching between shaded to unshaded cells. (e.g. 123-4-56-789)

I really liked this one. Very hard (for me), and took me 3.5 hours, but at the same time it never felt frustrating; there was always something to tweak or some options to narrow down until they revealed something. I'm very pleased, and somewhat surprised, that I didn't manage to break it at any point :-)

Wow, that's a good one ♥️
I gotta say:why would you double the UNshaded cells. That seems weird to me ^_^
X: Seems to be the standard for YY variant puzzles, which I agree is a bit weird, but the way I see it is that the shaded cells are the darker cells, so the lighter ones are the 'highlighted' ones. :)

This is equal parts stunning and insanity. Thank you so much!

This looks like a puzzle that invites a lot of mistakes, but miraculously I've managed to solve it without making any.

So, am I understanding correctly, in the example, the long arrow is 4 doubled = 8, which is 1 + 3 + 2 + 1doubled?
The top right is 3doubled = six, which is 1 doubled + 2 doubled,
And the bottom right is 4 doubled = 8, which is 1 doubled + 2 + 4...
Was very confused till i realized the number in the circle can also be doubled.
X: This is all correct :)
