 LEV   1 (20) 2 (20) 3 (20) PUZ

With the Skyscraper Sudoku, the numbers in the grid are seen as skyscrapers that, depending on the number, show 1 to 9 floors.

With this puzzle there are also CLUES outside the grid. These numbers indicate the number of skyscrapers that you can see from that position. If there is, for example, the number 1 in the border, the number 9 must be placed in the first box so that you can see only 1 skyscraper.

For example, if the number 3 is in the border and:

• if the first digit in the grid is digit 6
• if the second digit in the grid is digit 7
• then you can place 9 in the grid as the third digit

to meet the condition that you can only see 3 skyscrapers from that direction. In this example, the number 9 may also be in a different location on the condition that the number 8 comes behind number 9 to avoid seeing 4 skyscrapers.
