A Cleverly-Titled Logic Puzzle Blog: March Mutant 6: Crowd Nine (sum skyscrapers)

In this Crowd Nine puzzle, a number to the left or right of a row or above or below a column represents the sum of the numbers in that row or column which can be seen from that direction. A number is visible if and only if it is greater than any other numbers in the row or column between that number and the edge (and is blocked from being seen if a number greater than it is in the way). The rules are otherwise unchanged.
