Groupies have lots of blanks and no clues. Actually, there is one clue, the one word supplied for you in each puzzle. This word not only provides a couple of letters in adjoining words but also is a clue to the group from which the other words are to be drawn.
For example, if the word is CAR, then the other words are probably all vehicles, perhaps limited to those having internal-combustion engines.
Or perhaps not. But after all, it's the perhapses that make life interesting.
