What Is a Cryptogram? Definition, Types, and Examples

A cryptogram is a word puzzle in which a short piece of text, usually a famous quote, is encoded by replacing each letter with a different letter, and your job is to decode it back to the original. The word comes from the Greek kryptós ("hidden") and grámma ("letter"), so a cryptogram is literally "hidden writing." This guide gives you a clear definition of a cryptogram, shows how it works with an example, and walks through the main types you'll come across. Once you know what a cryptogram is, learning how to solve one takes just a few minutes.

Cryptogram, defined

At its core, a cryptogram is built on a substitution cipher: every letter of the alphabet is consistently swapped for another letter throughout the puzzle. If the puzzle replaces E with Q, then every E in the hidden quote appears as Q, with no exceptions. The solver's task is to figure out the full letter-for-letter mapping and reveal the original message.

Two features make cryptograms fair and solvable:

• Consistency. The same substitution is used everywhere, so cracking one letter reveals all its copies at once.
• Real language. The hidden text is genuine English (usually a meaningful quote), so the patterns of English, common words, letter frequencies, familiar phrases, give you the clues you need.

That combination is why a wall of gibberish can be unraveled by pure logic, no secret key required.

A simple example

Here's a tiny cryptogram. Each letter has been shifted to a different one:

WKH HDUOB ELUG = THE EARLY BIRD

In this example, W stands for T, K for H, H for E, and so on. Notice that the two E's in "THE" and "EARLY" both became H, and the consistency is what lets you confirm a guess: once you suspect H = E, you check every H in the puzzle and see if the words make sense. (If you spotted that this example is a Caesar shift of three letters, nice eye, that's one specific kind of substitution cipher, covered in types of ciphers.)

How is a cryptogram solved?

You solve a cryptogram with the patterns of English rather than a key:

• Single-letter words are almost always A or I.
• The most common three-letter word is THE.
• The most common letter is E, then T, A, O, I, N.
• Apostrophes, double letters, and endings like -ING narrow down the rest.

Because every guess propagates across the whole puzzle, the solution cascades once you place a few high-value letters. The full method is in our step-by-step solving guide.

Types of cryptograms

"Cryptogram" is an umbrella term, and a few named varieties show up often:

• Cryptoquote. A cryptogram whose hidden text is a quotation, often a famous one, sometimes with the author's name also encoded. This is the classic newspaper version. See what is a cryptoquote.
• Celebrity cipher. A cryptoquote where the quote is by or about a celebrity. A popular syndicated feature. See celebrity cipher.
• Cryptoquip. A cryptogram whose answer is a pun or play on words rather than a serious quote.
• Themed cryptograms. Collections built around a topic, science quotes, Bible verses, literary lines, so the hidden text comes from a known pool.

All of them use the same substitution-cipher mechanic. The difference is only in what the hidden text is and how it's presented.

Why people love cryptograms

Cryptograms hit a satisfying sweet spot. They're pure logic, no math and no trivia required, just careful reasoning from the structure of English. They deliver a steady drip of small victories as each letter falls, and they end with a reward: a memorable quote you've personally decoded. They're also endlessly renewable, since any quote can become a new puzzle, which is why they've been a newspaper staple for generations.

Cryptograms vs other word puzzles

Unlike a crossword, you don't need outside knowledge or vocabulary trivia, the answer is already written, just disguised. Unlike an anagram, the letters aren't rearranged, they're substituted, so word length and letter positions stay intact and give you structural clues. That makes cryptograms a uniquely "crackable" puzzle: everything you need is on the page.

Try one yourself

Now that you know what a cryptogram is, the best next step is to decode one. Our cryptogram puzzles come in five difficulty levels, from gentle quotes with a few letters revealed up to the Alan Turing tier with 25-word passages. Start with the solving guide, then crack your first quote.

Frequently asked questions

What is a cryptogram in simple terms?

A cryptogram is a puzzle where a quote is hidden by swapping every letter for another letter, and you decode it back to the original. The same swap is used throughout, so once you figure out a few letters, the rest of the message starts to fall into place.

What is an example of a cryptogram?

If you encode "THE EARLY BIRD" by substituting each letter, it might read "WKH HDUOB ELUG." The solver works out that W = T, K = H, H = E, and so on, until the original phrase is revealed. The hidden text is usually a famous quote.

What is the point of a cryptogram?

Cryptograms are a logic puzzle and a pastime. They exercise pattern recognition and deductive reasoning, require no special knowledge to solve, and reward you with a memorable quote at the end. They're popular in newspapers and puzzle books for exactly these reasons.

Are cryptograms and cryptoquotes the same thing?

A cryptoquote is a type of cryptogram, specifically one whose hidden text is a quotation. All cryptoquotes are cryptograms, but a cryptogram could also hide a pun, a proverb, or any phrase. There's a full comparison in what is a cryptoquote.
