Giant Book of Pencil Puzzles/Giant Book of Optical Puzzles: Two Books in One

The one type of puzzle that I never tire of no matter how many times I see it is the optical illusion. They continue to fascinate me as they demonstrate that the images our eyes transmit to our brains are subject to different interpretations, sometimes simultaneously. 255 pages of this book is devoted to optical puzzles, most of which have appeared in many other places and contexts. Unfortunately, all of the images are in black and white, so you will not see some of the more spectacular illusions based on colors. Nevertheless, they still amaze you. The other section of the book, also 255 pages, is devoted to puzzles that you use to pass the time on long and boring trips. These word searches, maze traversals, very short murder mysteries, themed crossword puzzles and vocabulary quizzes will keep you active and intellectually engaged during even the most boring waits or trips in your life. Solutions to the puzzles in both sections are included.
