As revealed in a preview DVD of an upcoming episode of "Crosswords" that was provided to TV critics this week, the "clues" are not nearly as difficult as "Jeopardy!," but they do present some challenges, especially since the time allotted for answering the questions is only a few seconds.
In the episode, the clues ranged from very easy ("slang for Internet businesses, three letters, 'Dot [blank]' - answer: 'com'") to more difficult ("Pan's place, nine letters - answer: 'Neverland' ").
