Yin Doubles Yang (Killer + Yin Yang)

(Published on 8. June 2024, 17:24 by damo_89)

I have enjoyed the many Yin Yang Sudoku hybrids on LMD and was inspired to set my own. Good luck!

  • Normal sudoku rules apply.
  • Yin Yang: Shade some cells such that all shaded cells are orthogonally connected, all unshaded cells are orthogonally connected, and no 2x2 area is entirely shaded or unshaded
  • Killer: Values in a cage sum to the value in the corner of the cage. A digit in a shaded cell counts double its value to the cage total. Digits may not repeat in a cage (but values may, e.g. 4 and doubled 2 summing to 8)

That break in is way too freaking slick. The rest of the puzzle was delightful enough to keep up with it as well.

Excellent puzzle! They way that the math had to work flowed great from cage to cage, from break-in to final disambiguation!
