How to Make Your Own Cryptogram by Hand

Making a cryptogram is even more fun than solving one, and it's the fastest way to truly understand how the puzzle works. Once you've encoded a quote and watched a friend crack it, you'll read every cryptogram differently. You don't need any software, just a pen, paper, and the steps below. This guide shows you how to make your own cryptogram by hand: pick a quote, build a substitution key, encode the message, and tune the difficulty so it's challenging but fair. (Prefer to skip the manual work? Our cryptogram maker does it instantly, but building one by hand teaches you the most.)

Step 1: Choose a good quote

Start with the message you want to hide. The best cryptogram quotes are:

• Short to medium length, roughly 5 to 15 words for a comfortable solve.
• Recognizable or meaningful, a famous saying, a proverb, or a fun fact, so the solver gets a satisfying payoff.
• Full of common letters. A quote rich in E, T, A, and O and ordinary words is fairer to solve than one stuffed with rare letters or unusual names.

Avoid quotes that lean on lots of J, Q, X, and Z, since those rare letters give the solver little to work with.

Step 2: Build your substitution key

Now create the cipher. Write out the alphabet, then assign each letter a different replacement letter:

Plain:  A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
Cipher: M K T V Z A Q W X P S L N B O Y H C U D E R F G I J

Two rules keep it valid:

• Each letter must map to a different letter, no two plaintext letters share the same cipher letter, or the puzzle becomes unsolvable.
• A letter shouldn't map to itself. If A encodes to A, you've leaked a freebie. Double-check none of your pairs match.

A quick way to build a key is to scramble the alphabet randomly, then fix any letter that accidentally maps to itself.

Step 3: Encode the quote

Go through your quote letter by letter and replace each one using your key. Keep these intact:

• Spaces between words, they reveal word lengths, which is fair and necessary.
• Punctuation like commas, periods, and especially apostrophes (they're strong solving clues, so leaving them in keeps the puzzle solvable).

So if your quote is "BE YOURSELF" and B→K, E→Z, and so on, you write out the encoded version letter by letter. Work carefully, one slip breaks the consistency and makes the puzzle impossible.

Step 4: Decide how much help to give

A cryptogram's difficulty is mostly about how much you hand the solver:

• Easy: Reveal three or four letters up front (write them in), and keep the quote short with common words.
• Medium: Reveal one or two letters.
• Hard: Reveal nothing, and use a longer quote so frequency analysis becomes the solver's tool.

This is exactly how our difficulty levels scale, from pre-revealed letters on easy up to the no-help Alan Turing tier.

Step 5: Test that it's solvable

Before you hand it over, make sure your cryptogram can actually be cracked:

• Re-solve it yourself from the encoded version, as if you'd never seen the answer. If you get stuck without the key, a real solver will too.
• Check for consistency. Confirm every instance of a plaintext letter became the same cipher letter, the number-one mistake in homemade cryptograms.
• Confirm fairness. A solvable cryptogram has enough common letters and short words to give the solver footholds. If it's all rare letters, soften the quote.

Tips for better cryptograms

• Keep the key handy as your answer sheet, so you can confirm a solver's answer.
• Add the author for a cryptoquote feel, encode their name too for a bonus clue, the way a celebrity cipher does.
• Theme your puzzles. A set of science quotes or movie lines makes a fun collection for friends or a classroom.
• Mind the apostrophes. Leaving contractions intact (don't, can't) gives solvers a fair entry point.

Share your creation

The real reward is watching someone crack a code you built. Once you've made one by hand, you'll appreciate just how carefully every cryptogram is constructed.
