1:25 There is obviously a 4 needed to be filled in r7c4 (full house), but that just shows 2 things: That you are human and that your videos aren't edited.
Oh, hello! This two were great Sudokus! I tried both of them. The first one I pencilmarked everything that I could than I watched your explanation. The second one I tried by myself first and I did find the 1, 2 and 3 skyscrapers! It took me 13:35 to finish the second. Thanks for the video! 🤗
I did the first puzzle without searching for a skyscraper. Near the end, I colored 58s which shortly became 5-not5s. Then I colored 78s, although I don't think it was necessary -- after doing it, I found a 78 seeing a 7. I found a skyscraper in 1s in the second puzzle, and it seemed to crack open the puzzle. I continued merrily along until I broke the puzzle by placing a 3 in the face of a 37 pair. Not knowing what to do, I backtracked to the skyscraper and wiped out the cornermarks and centermarks, and repopulated them, applying the skyscraper in the process. I found a second skyscraper, in 2s, and then a finned X-wing in 3s. That let me finish the puzzle properly this time. 1:10 The puzzle at this stage is screaming to be cornermarked. Also, I managed to solve this without a skyscraper. 2:30 I goofed and saw a non-skyscraper in columns 5 and 9. The END: I found a skyscraper in 2s. With 3s, I found a finned X-wing instead of a skyscraper.
5:02 I think I finally understand skyscraper. This kind of reminds me of if-then statements in coding. Also, on the second one, I found a UR. Idk if it's legit though since this is just about skyscrapers haha
First example - got to where only 5789 were in the centermarks, and started colouring 5's from the 58 pair in block 4 (although I could have started from anywhere in the band) That coloring eliminated 5's from R1C2 and R9C3, leaving an 89 naked pair in block 1 that cracked the whole thing.

Thank you for catching that full house, Robert. You have a good eye. 👁️

In example 2 isn't there an x-wing in there as well
