Once you have some pairs in place, you may be able to figure out that some spaces have to be blank because you have the first or last pair already in place. Put a dot in those boxes as a reminder, and you may then have some more words with the right number of spaces and no more blanks remaining.
One more hint before you resort to the grid. Click and drag over the text below to see the two answers that use all their spaces. There are no blanks in those spaces.
First answer with no blanks: [42 across]
Second answer with no blanks: [25 down]
Once you’re done, please peruse the Sunday brunch menu for more puzzles, including cryptics, diagramless, and more.
