Sudoku O.W.L.
(Published on 10. October 2022, 21:25 by Nahileon)
Normal Sudoku rules apply for the 9x9 in the center.
Killer: The cells in the cage add to 8.
XV/Kropki: Cells separated by a V add to 5. Cells separated by a black dot have a ratio of 2:1. Not all V's and dots are given.
A question mark outside the Sudoku indicates an X-Sum clue and an Arrow outside the Sudoku indicates a Little Killer clue. These clues have to be determined by the solver.
X-Sum: An X-Sum clue is the sum of the first X digits in the row or column from the direction of the clue, where X is the first of those digits.
Little Killer: A Litte Killer clue is the sum of the digits on the indicated diagonal. Digits may repeat along such a diagonal if allowed by the other rules.
Yin Yang: Shade some cells of the grid such that all of the shaded cells and all of the unshaded cells are orthogonally connected. No 2x2 contains four shaded or four unshaded cells. The black cells are not part of the Yin Yang.
Shaded digits in the Sudoku and clues outside the Sudoku are even. Unshaded digits in the Sudoku and clues outside the Sudoku are odd.
Solution code: Row 1 in the Sudoku.

Awesome puzzle! There aren't many clues so it really makes you think what is going on, and it's fun to discover!

Very clever setting especially given the near symmetric grid. The break in was beautiful and the clue placements were genius. I really enjoyed that. Thanks Nahileon
Although I think I now need to get my eyes checked. My finished owl looks like it has been struck by lightning :D

W.O.W! What a fantastic and mindbendingly original puzzle this is!
My intuition actually acted very poorly in the first half in terms of understanding how the YY works but it blew my mind almost completely once I saw it, and it's truly amazing to see how it solved afterwards ;)

Funky interesting yin-yang logic! Is a N.E.W.T. puzzle on the horizon? xD

Maybe ;)

Wow, surprising that this solves with so little information in the grid. Very interesting logic with the yin yang on a non-rectangular grid.

Thank you!
