Editing Cryptogram (section)

==Solving a cryptogram==
Cryptograms based on substitution ciphers can often be solved by [[frequency analysis]] and by recognizing letter patterns in words, such as one-letter words, which, in English, can only be "i" or "a" (and sometimes "o"). Double letters, apostrophes, and the fact that no letter can substitute for itself in the cipher also offer clues to the solution. Occasionally, cryptogram puzzle makers will start the solver off with a few letters.

A printed code key form (the alphabet with a blank under each letter to fill in the substituted letter) is usually not provided but can be drawn to use as a solving aid if needed.  Skilled puzzle solvers should require neither a code key form nor starter clue letters.
