Here is a little puzzle with the simplest possible conditions. Place the
point of your pencil on a letter in one of the cells of the honeycomb,
and trace out a very familiar proverb by passing always from a cell to
one that is contiguous to it. If you take the right route you will have
visited every cell once, and only once. The puzzle is much easier than
it looks.
