What is a Cryptogram?

Politicians and military strategists have used simple-substitution ciphers to encode their secret documents for thousands of years - even back to the time of Julius Caesar! The process is simple: change each letter in your document to another letter in the alphabet, so that your new document is completely illegible. Your new, encoded document might look a little something like this:

It looks like a whole lot of nonsense, right? Well, to many people, for many hundreds of years, it was nonsense - and the simple substitution cipher worked just fine to keep secret documents just that: secret. But eventually people started to realize these ciphers could be broken quite easily, using nothing but simple pattern recognition, frequency analysis and a general knowledge of grammar and vocabulary. Soon enough, simple-substition ciphers were no longer enough to keep encoded documents safe from prying eyes, and those who wanted to keep their secrets secret moved on to more complex encryption methods.

While no one uses cryptograms (a type of simple-substitution cipher) today to encode their secret documents, they have survived to become a wildly popular puzzle, available in thousands of books and newspapers... and of course, web sites!
