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.

Smaller example with the numbers 1 through 6:

Puzzle:

Put the numbers 1 through 9 into the hexagonal cells so that every line (of any length) contains every digit not more than once. 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. If there is no dot then neither the difference is 1 nor one cell the half of the other. The dot between two cells with 1 and 2 can have any of these two colors.

Puzzle:

Put the numbers 1 through 7 into the hexagonal cells so that each of 7 large hexagons and every line (of any length) contains every digit not more than once.

Put the numbers 1 through 7 into the hexagonal cells so that each of 7 large hexagons and every line (of any length) contains every digit not more than once.

Put the numbers 1 through 7 into the hexagonal cells so that every line (of any length) contains every digit not more than once.

Put the numbers 1 through 7 into the hexagonal cells so that every line (of any length) contains every digit not more than once.

Fill in the grid so that every of the lines in the three marked directions and every circle contains the digits 1 through 6.

Fill in the triangles around each circle the digits 1 to 6 so that each digit is only used once per circle.

Put the numbers 0 through 9 into the triangular cells so that every line (of any length, in three directions) contains every digit not more than once.
