When regular crossword puzzles prove too easy, wordsmiths need a harder challenge. Diagramless crosswords offer a new trial of wits and intelligence for even the most devoted acrostic lover.

Imagine your typical crossword puzzle, with clue numbers and black squares separating each answer. Now remove the black squares. Not challenging enough for you? Remove the clue numbers as well. Now you're looking at a blank grid. You don't just have to solve the puzzle clues-you must figure out where the clue answers and black separation squares fit on the board. It's a challenge unlike any other.

Diagramless Crosswords: Volume 3 is puzzle creator Richard Emmons's third foray into the bewildering, mind-bending world of diagramless crosswords. Inside this collection, you'll find seventy-five puzzles of varying difficulty.
