All of my 'clue' words do not appear in my Crossword Puzzle. Is there a limit to the number of words used in a Crossword Puzzle?

There is no maximum limit to the number of words that can be used in a crossword puzzle. However, the puzzle generator is limited to 25 characters per word.

The puzzles can only generate puzzle variations where the words fit. In order for all of the words to be used, be sure the words can be placed together in one puzzle.
