Place the digits from 1 tot 9 in every row, column and 3x3-block. Every digit represents a skyscraper with the same height. Clues outside the grid indicate the number of visible skyscrapers from that side. Higher skyscrapers block the view of lower ones.
There are 8 glass skyscrapers, of heights 2~9 with no repeat.All known hint numbers given are not glass skyscrapers. Glass skyscrapers do not block the view, so, if you see the glass buildingitself, it will also be counted.
A group of skyscrapers is 123947658. The glass skyscrapers in this row are 9, 7, 6. From the left side, the skyscrapers you can see are 1|2|3|9|4|7|6|5|8, the number of skyscraper observations is 9. From the right side, the skyscrapers you can see are 8|9, and the number of skyscraper observations is 2.
Solution code: Row 9, followed by Column 9.

Really cool puzzle. Very different and challenging due to the glass skyscrapers (and the lack of any restriction regarding the number of glass skyscrapers per box/row/column).
