Combining cognitive exercise and entertainment, the word scramble puzzles in this collection become increasingly difficult through the book, and incorporate trivia that tests knowledge on a wide variety of subjects and either provides clues to answering the puzzle or creates a greater challenge. For more than 40 years, millions of newspaper readers have delighted in solving Jumble®, which appears in hundreds of national papers and in these puzzle books that offer hours of challenging wordplay and fun. Each page features a series of mixed-up words coupled with clues, and one letter from each word is used to form the answer to the puzzle.
