Nosedive (8x8 Yin Yang 9-Lines)
(Published on 18. November 2024, 17:23 by Florian Wortmann)
This puzzle is inspired by zetamath's Baby Dragon.
Normal 8x8 sudoku rules apply.
Yin Yang
Colour every cell in the grid in one of two colours such that the cells of each colour are orthogonally connected and no 2x2 is entirely one colour.
9-Lines
Divide each line into non-overlapping segments, each of which sums to 9. Digits may repeat within a segment if allowed by the other rules.
Additionally, along each line, each of these segments must all be one colour, and two adjacent segments cannot be the same colour.

Baby Dragon is one of my favorite puzzles, and this is a fantastic companion piece! The 8x8 grid and 9-lines work so well together. Absolutely loved it!
