Increasing in difficulty through the book, this collection of word-scramble challenges adds fun to cognitive exercise and has the added element of a larger puzzle to be solved on each page, testing the reader's knowledge of such topics as history, geography, and science. 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.
