One of the 9 ingredents of the Erzgebirgian christmas meal, called Neinerlaa, are Griene Kließ (Green Dumplings). The circles in our puzzle, an Hanidoku, look like these dumplings.

Put the numbers 1 through 9 into the hexagonal cells so that every line (of any length) contains every digit not more than once. The lines must contain consecutive numbers, i. e., if a line has five cells there can be 2, 3, 4, 5, 6 or 3, 5, 4, 2, 6 but not 3, 4, 1, 9, 8 in the cells.

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. If there is no dot then neither the difference is 1 nor one cell the half of the other.

Fill in the grid so that every row, every column and every 3x3 box contain the digits 1 through 9. On each line one cell is the sum of the others.

Fill in the grid so that every ring, spoke, 3x3 box and every colored spiral contains the digits 1 through 9.

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 cube so that every outlined region and every layer (as shown by the double arrows) contains the digits 1 through 8.

Puzzle:

Fill in the grid so that every with an arrow marked line and every bold marked region contains the digits 1 through 8.

The coloured lines in this grid should help to understand the rules:
