HalfYin-TwoYang

(Published on 11. January 2023, 15:37 by DJV)

Rules

Normal sudoku rules apply.

Yin/Yang: Shade some cells so that all shaded cells are orthogonally connected, and all unshaded cells are orthogonally connected. No 2x2 area may be completely shaded or unshaded.

Killer: The digits in a cage may not repeat, and must sum to the small number in the top left corner of the cage. Shaded digits count as half of their value towards cage totals, while unshaded digits count as double their value.
