5 Cryptogram Riddles With Hidden Messages To Test Your Intelligence

Solving a certain type of puzzle that involves deciphering and encryption is called a cryptogram. Today, you will be attempting to solve 5 different cryptogram riddles! These puzzles are incredibly fun, but they weren’t always used for entertainment.

Originally designed for keeping military secrets from spies, cryptograms held great importance. Even Julius Ceasar used this method of encryption. So much so, that a type of cipher was named after him.


According to Suetonius, who wrote a set of biographies of Julius Caesar in 121 A.D.: “If he had anything confidential to say, he wrote it in cipher, that is, by so changing the order of the letters of the alphabet, that not a word could be made out. If anyone wishes to decipher these, and get at their meaning, he must substitute the fourth letter of the alphabet, namely D, for A, and so with the others.”


The easiest way to understand the Caesar cipher is to think of cycling the position of the letters. In a Caesar cipher with a shift of 3, A becomes D, B becomes E, C becomes F, etc. When reaching the end of the alphabet it cycles around, so X becomes A, Y becomes B and Z becomes C.
