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

Example:

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. The greater less sign show in which cell the greater value is.

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. 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.

Puzzle:

Put the numbers 1 through 6 into the hexagonal cells so that every line (of any length) contains every digit not more than once. The numbers around the grid are the sum in the direction of the arrows.

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.
