Cracking Codes & Cryptograms For Dummies provides an introduction to the use and function of codes and cryptograms in the world of secret societies and their connections to conspiracy theories, as well as over 300 different puzzles of varying skill levels from the simplest substitution puzzles to fiendishly difficult ciphers that test the readers' ability to find the hidden answer and meaning in the clues. The types of puzzles include: Cryptograms with letter substitutions, number substitutions (A=1, B=2, etc.), and symbol substitutions (A=♦, B=, etc.), Riddles and Wordplay     o     Anagrams--rearranging the letters of a word or phrase to produce a new word or phrase.     o     Rail Fence Ciphers--where a message is set-off in two lines, alternating letters, then break into sets of letters     o     Shift Ciphers--also Called Caesar ciphers where there is a shift of number of letters in the alphabet     o     Masonic cipher/Freemason's cipher--substitution cipher exchanging letters for symbols based on a grid.     o     Twisted Path Ciphers--use a keyword to determine the order columns of letters are arranged in, according to the relative alphabetic position of the letters in the keyword, so KITE = 3241 (K is 3rd in alphabetical order within the word, I is 2nd, T is 4th, and E comes 1st), WRIGHT (= GHIRTW in alphabetical order) = 643125.      o     Double level Ciphers--by solving one cryptogram you get a keyword, which then allows you to crack the encryption on a different kind of puzzle. In addition, a chapter is devoted to messages that, when decoded, add to an overall 'mystery' which can be revealed when the entire book is decoded.
