Two Colour Theorem
(Eingestellt am 8. Mai 2024, 15:22 Uhr von FullDeck-Missing)
Normal sudoku rules: Every row, column, and box must contain a complete set of the digits 1-9.
Yin-Yang: Shade cells using two colours such that each colour forms an orthogonally connected region, and no 2x2 area is a single colour.
Sight Lines: Digits in caged cells indicate how many cells of the same colour are seen orthogonally from that position, including itself. The other colour blocks vision.
Region Sum Lines: Box borders divide blue lines into segments with the same sum. Along lines, colours must change at box boundaries and may not change within the box. The intersecting lines at R34C89 each continue straight and do not branch.

Lösungscode: Row 6, left to right, 9 digits no spaces.

Beautiful. Love, how you always have to take care on all the different rules!

That was a very nice solve. I love it when yin-yang is integrated so nicely into the rest of the puzzle; it felt like all the different pieces were working together to help me solve it.

Wow, this one was a LOT of fun to solve. Had to keep switching between "modes of thinking" to see how the different constraints were interacting. Very cool!
