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.

Smaller example with the numbers 1 through 6:
