Yin Yang Masyu Permaculture
(Published on 26. March 2024, 09:00 by Agent)
Divide the grid into two areas of orthogonally connected cells. The first area is a Yin Yang, the other is a Masyu (Full).
Yin Yang: Shade some cells in the Yin Yang area such that all shaded cells are connected and all unshaded cells are connected. No 2x2 box may be fully shaded or fully unshaded. Black circles must be shaded. White circles must be unshaded.
Masyu (Full): Draw a non-intersecting loop through the centers of all cells in the Masyu area. The loop must turn on black circles and travel straight through the cells on either side. The loop must go straight through white circles, and turn in at least one of the cells on either side.
Puzzle links
Solution code: Column 9 (3rd-to-last) from top to bottom. S for a shaded cell, U for an unshaded cell, L for a turn of the loop, I for a straight segment of the loop.

My first permaculture! Wonder why I felt the urge to try one of these...

Masyu and YY definitely get along pretty well! This was a great way to renew the old YY habits, thanks

Really fun! This is the first permaculture I've solved, and I loved every minute of it.

bizarre (in a good way) combination of rules! i really enjoyed this, gave a fascinating new flavour to the yinyang ruleset.

Updated German rules.

Very nice.
A mistake in the German version: "Weiße Kreise müssen nicht schattiert sein." must be changed to "Weiße Kreise dürfen nicht schattiert sein."

I really enjoyed this! Lots of fun interactions, and I think accessible to people who are not very experienced with the genres. Thank you!

Wonderful puzzle! Quite easy if experienced in both rulesets, but still very original, interesting and rewarding.
