Here's a new puzzle by me. I'm not sure if the combination of the 2 has ever been done before. I can't remember ever seeing it. If it has been done before, feel free to correct me.
Outside Skyscraper Sudoku
Fill the grid with the digits 1-9 so they appear once in every row column and marked 3 by 3 area. Outside the grid are pairs of clues. Of each pair one clue is an Outside Sudoku clue and one is a Skyscraper Sudoku clue. The Outside Sudoku clues indicate that the digit appears in one of the first 3 cells of that row or column from that side. The Skyscraper Sudoku clues indicate how many digits are visible from that side. Smaller digits hide behind larger digits.
