Normal 6 by 6 sudoku rules apply (place the digits 1 to 6 once each in every row, column and 2 by 3 box).
Every row and every column functions as a zipper line where digits of an equal distance from the centre of the line sum to the same total.
Each number in the grid indicates the height of a skyscraper in its cell, a clue outside the grid indicates the number of skyscrapers visible from that direction (where taller skyscrapers block shorter ones from view). The 3 just outside the bottom left corner of the grid is a skyscraper clue for the positive diagonal.
Digits connected by a region border may not sum to or multiply to 5.
Solution code: Column 1 read from top to bottom.

The break-in is obvious, and I agree with ParaNox that the final disambiguation could probably have been done in a more satisfying manner. A nice two minute snack, though.

how does the zipper line work? (sorry for being slow). can it cross over from collumn 1 to collumn 6? does it have to be minimum 3 cells or the entire row/collumn?

Surely this is an obvious 1 star, no?
