Growing YY in the Fog Puzzle Pack
(Eingestellt am 29. Mai 2026, 20:13 Uhr von SennyK)
Today, after around half a year since I started, I am very happy to share with you puzzle pack which consists of 9 chapters, after solving one of them you will get a link to the next one in the completion message :-)
Firstly, I would really like to thank DubiousMobius who has grately helped me with the visuals for the whole pack!
Secondly, a huge thank you to my wonderful Testers: NicoD, Suntanman3 - Ben, FIT7Y, Kafkapharnaum and Aletheia!
This puzzle pack is given 5* difficulty not only because there are 9 puzzles, they are also very hard.
gdc has created a script, which can be installed via Tampermonkey. It allows to check in SudokuPad if centermarks/cornermarks are correct, but it also allows setters to create a solution for Yin-Yang. If you install this script, you will be able to check during your solve if your colors for Yin-Yang are correct. Here is the link to his script: Extended Checks
If you need a nudge, feel free to reach me on Discord (SennyK7) or ask in the hidden comment, I will answer by editing it :-)
I hope you will enjoy and I would be really grateful for all the comments and ratings.
There are different rules in each chapter, however some of them are common and you can see them below:
Dynamic Fog of War: The grid is partially covered in fog. Placing correct digits reveals their own cell and may also lift fog elsewhere in the grid. No guessing is required.
Yin-Yang: Shade some cells in the grid so that all shaded cells are orthogonally connected, all unshaded cells are orthogonally connected, and no 2×2 region is entirely shaded or entirely unshaded.
Values: A shaded cell containing digit x has value ??? (differs between chapters); an unshaded cell has value equal to its digit.
Golden Clues (GC): In each puzzle, you are going to get one new clue inside a golden cage with the number of the current chapter in the top left corner. A clue consists of a digit and its shading. Each clue is going to exist somewhere in the grid in all of the following chapters. Every time you find a golden cage with the number of the one of the previous chapters in the top left corner, you can fill it right away with the digit and shade it accordingly. Every time you find a golden cage with the number of the current chapter in the top left corner, it is a new clue to be used in the following chapters.

Fabulous pack with too many highlights to mention them all. Every time I was in awe with a puzzle, the next was even better. A well worthy 5 star rating for the final 4 or 5 puzzles and so for the pack. Now there is just one more thing to do... Thanks!

I would rate this if I could beat it lol
Stuck on chapter 8 but I'm ok with that
Very very nice

Note for the solution code: There is a symbol "/" between 2nd row and the golden clues. I doubted whether my efforts are in vain when I failed first try.
SK: Thank you for the comment, there is "/" there because shading is different

Very difficult, but never unfair. Amazing series.

Very well done! Extremely tough at times but exceptionally rewarding. I don't want to spoil anything but I especially liked the puzzles with circles/squares.
I will say that chapter 8 is absolutely brutal in some of the deductions you have to make. Almost made me give up, but after taking a break and coming back to it I was able to break through and boy am I glad I stuck with it

A bit late to the testers’ party, but here I am, finally! Many thanks for having included me in that most ambitious project, full of really unique YY logic, so much so that even its most well known (non)secrets themselves feel original when they finally come up.
I don’t want to spoil anything with my comment, so I will just confirm what wuc’s has touched on, which is that for sure, the difficulty ramps up significantly after the first few, tutorial-like puzzles, but it is all really worth it to hang on all to way to the last one. Well done in all regards!

Some very satisfying deductions and logic steps. Definitely worth a go even if the difficulty level intimidates. I was able to do this, and I consider myself a 4/5 solver.
