A cryptogram is a type of puzzle which consists of a short piece of text encrypte with a simple substitution cipher in which each letter is replaced by a different letter. To solve the puzzle, one must recover the original lettering. Though once used in more serious applications, they are now mainly printed for entertainment in newspapers and magazines. There is also a type of cryptogram in which you have an already written article and you number each word. The first word would be One and the second would be Two... Then you write the cryptogram using the numbers of the first letter of that number's word. example; 1.hi 2how 3are 4you? 2-3-4 would be h-a-y. This is harder because the article has to have a word for every letter in the cryptogram. The person decoding would have to have the article and number it to solve the cryptogram.
