(no subject)
Here's another Hidden Skyscraper Sudoku. I think it's a bit easier than the other two, although that may be because I'm getting better at solving them. It has a few more arrowed squares than either of the other ones, though, so I think that makes things a bit easier.
I learned an important (well, interesting, anyway) theorem while constructing this puzzle: If a square has all four arrows, then at most, it's a 3.

Edit: There were two mistakes in this puzzle. I've fixed them and re-solved the puzzle, and uploaded a corrected image. Sorry for any inconvenience this may have caused you.
