Draw a loop into the diagram which runs on the edges of the fields and does not cross or touch itself.

The meaning of the given hint numbers depends on whether they are outside or inside the loop. Numbers outside the loop indicate how often the corresponding field is touched by the loop. Numbers inside the loop are cave hints. They indicate how many fields can be seen in total in horizontal and vertical directions, including the field itself.

Each hint is "knapp daneben", i.e. too big or too small by 1.

The colour of the hint numbers has no meaning for the puzzle.
