(Published on 15. July 2024, 05:59 by The Bard)

Positive Negativity 2

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.

Solve on CTC

This is a sequel to “Positive Negativity” which you can find HERE.

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.
