Next 3 puzzles are skyscraper puzzles. The rules of a skyscraper puzzle are as follows: In every row and column skyscapers are built with each a different height. The numbers around the map tell you how many skyscapers you can see when looking from that side. you can see a skyscraper only when all the skyscrapers in front are smaller. Example looking from left to right we will see 3 skyscrapers in the sequence 1,4,5,2,3. And looking from right to left we will see only 2 buildings. All possible heights are used exactly once in every row and column.
