"Row 1 Column 1 of each 6x6 grid" is confusing. If you treat them as 6x6 grids, most of them have nothing in row 1 column 1. They're all 4x4 sudokus, so why not just say "4x4 grid"?

Wow can't believe you're the first to mention the typo there. Thank you, fixed

I found Nextdoor unreasonably challenging for some reason, but the rest were very nice

Brilliant puzzles!
Typo in solution code: 4x4 instead of 6x6

Fun! Each one forced me to think about how the skyscraper numbers related to each other. Though, the number of times I had to remind myself that numbers could repeat along a skyscraper-hint row/column...

Its cool that just the little 2 difference whisper is enough. Thanks for the snacks.

Lovely set. Just a nitpicky point about the Solution code though. I think what you require is actually R1C1 of each sudoku grid. In some cases the puzzle contains (or might be understood to contain) a number further to the left.

Thanks, clarified that.
