Positive Negativity 5
(Eingestellt am 3. November 2025, 06:35 Uhr von The Bard)
Normal Sudoku rules apply, place the digits 1-9 in each row, column, and box.
Yin Yang: shade some cells so that all shaded and unshaded cells form 2 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, and DIGITS may not repeat in a cage.
This is a sequel to Positive Negativity,

This is a neat concept, but too difficult for my lack of familiarity with the negativity constraint. Marked a few squares as positive/negative, figured out the parity of some more, and got fully stuck.
Guess I'll see if any of the others in this series are easier introductions :P
