Ban it twice! (Yin Yang, Renban)
(Published on 17. August 2023, 22:41 by Paletron)
- Normal sudoku rules apply.
- Yin Yang: Shade some cells such that all shaded cells are orthogonally connected and all unshaded cells are orthogonally connected and no 2x2 area is fully shaded or unshaded. The gray cell in the middle should be ignored for shading, it isn't shaded nor unshaded.
- Sight Lines: Digits in circles show the number of cells of the same color (shaded or unshaded) seen orthogonally from that position, including itself. The 'other' color blocks vision.
- Modified Renban: Along pink lines, digits of the same color (shaded or unshaded) each form a consecutive, non-repeating sequence in any order (sequences of length 1 are allowed). Each line contains at least one repeated digit
Enjoy!
Solution code: Row 5 (9 digits)

Exceptionnally good ! Every clue in that puzzle is super original and interesting. The logical path is clear, and I'd say this is a 3.5-4 for me. Thanks !!

This was an outstanding puzzle. Same as the first commenter, I found it very difficult (5 stars imo). But unlike some other difficult puzzles, I never got stuck for too long, and steadily clambered my way through the interactions.
This was really phenomenally set, I loved how much there was to work out and think about. I tried out this puzzle because of the Building Between puzzle that got featured, and the enthusiasm of the first commenter. I will try whatever else you publish!

This was extremely hard. I don't think is a 3 star puzzle. Took me almost 6 hours to solve (usually a 3 star puzzle takes me 1 1/2 hours). It was a lot of fun and it is extremely satisfying to solve it after all that time. You are a very good setter. Underrated.
