Cryptograms are word puzzles that feature encrypted sentences that solvers must decipher to reveal a message; in each puzzle, every letter is consistently replaced with a new letter (for instance, "Star Wars" might be encoded as THIS LIST). The solving process exercises both sides of the brain, as logic and letter patterns come into play in tandem. Author Stanley Newman provides entertaining and little-known facts that are sure to delight the solver once decoded.For instance, did you know light bulbs in NYC's subway system turn in the opposite direction from standard bulbs, to discourage people from stealing them?
