Cryptogram

A cryptogram is a specialized type of word puzzle.

It consists of a short piece of encrypted text. This means the message is hidden behind a code. Most cryptograms use a method called a substitution cipher. In this system, every letter is replaced by something else. This replacement could be a different letter, a number, or a symbol. The goal for the solver is to recover the original lettering. While these were once used for high-stakes secrets, they are now mostly used for entertainment. You can find them in many newspapers and magazines today.

To solve a substitution cryptogram, you must look for specific patterns.

One common method is called frequency analysis. This involves looking at how often certain characters appear. In the English language, some letters appear more often than others. You can also look for very short words. For example, a one-letter word in English is usually "i" or "a." Sometimes it might be "o." Other clues include double letters and the placement of apostrophes. A key rule is that no letter can substitute for itself. If you need help, you can draw a code key. This is a simple chart showing the alphabet with blanks underneath. Skilled solvers often do not need this aid.

There are several distinct types of these puzzles. A Cryptoquip is a specific version that often includes a clue or a pun. The final solution is usually a witty or humorous phrase. Another type is the Cryptoquote, which uses a famous quote as the hidden message. There is also a puzzle called the Cryptoquiz. In this version, the top of the page shows a category, such as "Flowers." Below that category is a list of encrypted words related to that topic. You must solve the entire list to finish the challenge. Some modern puzzles even use numbers similar to those used in texting.

The history of these codes is quite serious. They were not originally created for games or magazines. Instead, people used them for real encryption of military or personal secrets. During the Middle Ages, monks began using them for intellectual games during their spare time. A manuscript found at Bamberg provides a specific historical example. It mentions Irish visitors to the court of Merfyn Frych ap Gwriad in Wales. This king died in the year 844. The visitors were given a cryptogram that required transposing letters from Latin into Greek.

As time passed, the study of these methods grew. Around the thirteenth century, an English monk named Roger Bacon wrote about them. He listed seven different cipher methods in his book. Bacon believed that a person should always hide their secrets from the common people. Much later, in the 19th century, Edgar Allan Poe helped make cryptograms popular. He included them in many newspaper and magazine articles. This helped move the practice from secret military use into the world of public entertainment.

Today, many famous brands distribute these puzzles to the public. King Features provides syndicated puzzles like Cryptoquip and Cryptoquote. Another company, Andrew McMeel, distributes a game called Celebrity Cipher. This game challenges players to decrypt quotes from famous personalities. Even authors use them for unique challenges. In September 2014, writer J.M. Appel announced a public challenge. He used the table of contents from his book, "Scouting for the Reaper," as a cryptogram. He even offered an award to the first person who could solve it.

Cryptograms are part of a larger field of study. They relate to the history of cryptography, which is the science of secret writing. Some puzzles even have religious connections. For instance, a newer puzzle called CodedWord uses a biblical theme. This version is found online and provides a short exegesis, or explanation, of the biblical text. Other puzzles have been used in much darker contexts. The Zodiac Killer sent four cryptograms to the police while he was active. Only two of those four messages have ever been translated. These puzzles show how a simple idea of swapping letters can be used for fun, for study, or for secrets.
