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 (R), 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.
