Fill the grid with the digits 1 to 9. Each row, column and 3x3-box has exactly one of each digit. All occurrences of each shape outlined in black (rotated and/or mirrored) must contain the same set of digits (possibly in different orders). None shape contains a repeated digit.

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. 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 2 in the first column means that the 2 in the second column is in row 6 - 9.
There is only one solution. You can find it by logic.

Fill the grid with the digits 1 to 9. The digits represent the height of the skyscraper in each cell. Each row, column, 3x3-box and marked diagonal has exactly one of each digit. 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 9. The digits represent the height of the skyscraper in each cell. Each row, column and 3x3-box has exactly one of each digit. In the marked diagonals no digit can appear more then once. The clues along the edges tell you how many skyscrapers you can see from that vantage point.

Fill in the grid so that every row, every column, and 4x2 box contains the digits 1 through 8.

Fill in the grid so that every row, every column, and 5x2 box contains the digits 0 through 9.
