Normal Sudoku Rules Apply. Place the digits 1-9 in each row, column, and box.
Ying Yang: shade some cells so that all shaded and unshaded cells form 2 form orthogonally connected areas such that no 2x2 area is entirely shaded or unshaded, and all the digits values in the shaded area are negative values.
Killer Cages: VALUES in cages add up to the total in the corner.
Kropki Dots: consecutive VALUES between 2 cells are indicated by a white dot, not all dots are given.

Brilliant puzzle! A more challenging break in than the first one but still very approachable. Definitely one of the best puzzles out of the few that I've solved!

Thank you for the great compliment. I know I have a lot of competition so that means a lot.

Same rulset as the first but a nice different set of clever ideas. Break in a bit tougher. Very much fun to play thx.
~~
I am glad you enjoyed the puzzle, I wanted to keep the same theme but make it a little more interesting and challenging. Can’t make these too easy.

Very enjoyable. My first yin-yang. The break-in felt obvious once I saw it, but that took a few minutes! Very clever design elements throughout.
~~
You got your first Yin Yang on my puzzle, I feel honored. They are a lot of fun once you start to unperstand their logic.

There appears to be a glitch on here, or I'm not understanding the rules correctly. The cage in box 8 has a total of 1, and the cage connecting boxes 7 and 8 has a total of 2.
~~
That is made possile through the negative digits that together add up to 1 or 2 respectively. This actually is an important clue in the solve for the Yin Yang.
Would you like a further explaination of the rules to help?

Very nice puzzle once I read the rules right. Before that I got really stuck.
~~
There certainly are a couple important details in the rules. I know I have had more than a few puzzles that I jumped into that suddenly hit a wall until I went back and read the rules.

Appologies to all. I did have the wrong solution code. I had updated the puzzle before I published it from an error. It should be fixed now.
