- Normal sudoku rules apply.
- Yin-Yang: shade some cells such that all shaded cells are orthogonally connected and all unshaded cells are orthogonally connected. No 2x2 area may be fully shaded or fully unshaded.
- Kropki: digits separated by a black dot must have a ratio of 1:2. Additionaly, a black dot always separates a shaded and an unshaded cell. Not all dots are necessarily given.
- Skyscrapers: shaded digits in the grid represent skyscrapers of that height, with taller skyscrapers obscuring smaller ones. A clue outside the grid shows the number of all visible skyscrapers from the clue's direction. Unshaded digits do not affect the outside clues.
Solution code: Shaded digits in row 5, left to right.

"Unshaded digits are not skyscrapers, they're just symbols carved into the ground" :D

If a complete row/col is all unshaded, will its clue be a 0?
-----
Black_Doom: yes, I'd say so. Although, there's very few places where a 0 clue could work!

Don't think I used the clue on top of C2.
