Fill the grid with the digits 1 to 9. The digits represent the height of the skyscraper in each cell. Each row, column and 3x3-box will have exactly one of each digit. The clues along the edges tell you how many skyscrapers you can see from that vantage point.
In each 3x3 box their is a different rule to follow:
Fill in the grid so that every row, every column, and every 3x3 box contains the digits 1 through 9. The arrows show the location of the same number in the previous or next column or row. So for example, the arrow next to the 9 in the first column means that the 9 in the second column is in row 1 - 4.

There is only one solution. You can find it by logic.
