Normal sudoku rules apply.
Killer Cages - Digits in a cage do not repeat and must sum to the number in the top-left corner of the cage.
Arrows - Digits along an arrow must sum to the number in the attached circle.
Skyscrapers - Digits outside the grid indicate how many cells are visible from the direction of the clue, with higher digits blocking the view of lower digits.
Note: In this puzzle, each skyscraper clue is also an arrow sum.
Solution code: Row 5
