Rules
- Normal Sudoku rules apply.
- Digits along a red Parity line alternate between odds and evens.
- Digits in a Quadruple circle must appear in the surrounding four cells.
- Digits in the grid represent the heights of skyscrapers on their cell. Digits outside the grid indicate the number of skyscrapers that can be seen in their line of sight, given that taller skyscrapers obscure all shorter skyscrapers behind them.
Play in SudokuPad
I wanted to play with similar concepts as in Parity Hammer, but slightly less easy. I settled on Skyscrapers as a fun element to add and take away such heavy reliance on Quads. Anyway, hope you enjoy the end result!
Solution code: Column 6 digits, top to bottom

I was never good at skyscrapers so this was a nice one to ease in on. Thanks!

A very pretty parity puzzle. The odds are all quick to figure out, leaving the evens to puzzle through about the skyscrapers.
@Martina: for a 2-skyscraper, the digit closest to the border doesn't have to be 8, it just has to be taller than everything between the border and the 9. (2)4139 is a valid skyscraper, since only the 4 and 9 are visible.

@Martina 8 could be hidden behind 9

I don't get the skyscraper rule. To me, R1C2 and R9C8 should both be 8, because you can see them and the 9s some distance behind. But they are not 8s. Please clarify.
