Fill the grid with the digits 1 to 7. The numbers within the bold border represent the height of the skyscraper in each cell. Each row and column in that square has exactly one of each digit. The numbers outside the bold border tell you how many skyscrapers you can see from that vantage point.

If the difference between two cells is 1 then there is a white dot. If digit in a cell is the half from a neighboring cell then there is a black dot. The dot between two cells with 1 and 2 can have any of these two colors.

Fill in the grid so that every row and every column contains the numbers 1 through 6. The digits represent the height of the skyscraper in each cell. The marked boxes must contain consecutive numbers, i. e., if such a box has three cells there can be 3, 4, 5 or 3, 5, 4, but not 3, 4, 6 in the cells. The clues along the edges tell you how many skyscrapers you can see from that vantage point.

Fill the grid with the digits 1 to 6. The digits represent the height of the skyscraper in each cell. Each row and column has exactly one of each digit. The clues along the edges tell you the product of the skyscrapers you can see from
that vantage point.

Fill the grid with the digits 1 to 6. The digits represent the height of the skyscraper in each cell. Each row and column has exactly one of each digit. The clues along the edges tell you how many skyscrapers you can see from
that vantage point.

Numbers in green cells are even, numbers in yellow cells are odd.

The colored squares along the edges tell you whether the number of skyscrapers you can see from that vantage point is odd (yellow squares) or even (green squares).

Fill the grid with the digits 1 to 6. Each row and each column has exactly one of each digit. Each red region must contain exactly 1 pair of numbers. Each cyan region must contain exactly 2 pairs of numbers. Each yellow region must contain exactly 3 pairs of numbers.

The clues along the edges tell you how many skyscrapers you can see from that vantage point.

Fill the grid with the digits 1 to 6. The digits represent the height of the skyscraper in each cell. Each row and column has exactly one of each digit. The clues along the edges tell you how many skyscrapers you can see from that vantage point.

The arrows show the location of the same number in the previous or next column or row. So for example, the middle arrow in the first column means in column 2 is in row 4, 5 or 6 the same number as in the cell with the arrow.

Fill the grid with the digits 1 to 6. The digits represent the height of the skyscraper in each cell. Each row and column has exactly one of each digit. The clues along the edges give you informations about the number of skyscrapers you can see from that vantage point.
