A twist on an unusual variant that I have solved some examples of recently and enjoyed so much that I wanted to create my own:
Standard Sudoku rules apply.
Each digit in the grid represents a skyscraper of that height. Clues outside the grid give the height of the first skyscraper that cannot be seen when looking into the grid from the position of the clue. A skyscraper is visible only when it is taller than all buildings in front of it.
All possible odd clues are given. That is, if there is no clue in a particular position, then the first skyscraper that can not be seen from that position must not be odd
Solution code: Row 6, Column 5

Time well spent! I thought I'd solved this long ago but the database claimed otherwise.

Gorgeous logic! I might have had a slight advantage from having made the skyscraper with id=0004C7 (the grey skyscraper clues have similar logic to that of the 1s in this one).

A completely new puzzle type with unexpected and non-obvious logic. Highly recommended!

Very challenging with lots of clever logic throughout

Nach dem Einstieg (danke an Hausigel und Semax) ein wunderbares Rätsel, das man nicht mehr weglegen kann :)
