A cryptogram is a puzzle written in code or cipher. Inspired by spy movies, these puzzles challenge you to decode jumbled words or phrases by figuring out an unknown letter substitution cipher. But what’s the best way to start cracking these intriguing codes?
Most cryptograms use single-transposition keys, where each letter is substituted for another. This creates seemingly random gibberish, such as:
- Example Cryptogram: Ygua ua gpq smtpmr xsm zrsem gpq yp apzbr xetoyphesna.
Fear not—there are systematic methods to decode these puzzles by leveraging patterns in the English language and making educated guesses.
Step 1: Identify High-Frequency Letters
English has common letters that appear frequently: E, T, A, O, N, I, S. Start by analyzing which letters recur most in the cryptogram.
- Example: In Ygua ua gpq smtpmr..., the letters M, R, S appear multiple times. These likely correspond to common letters like E or T.
Step 2: Decipher Short Words First
Tackle two- or three-letter words first—they’re often pronouns, articles, or prepositions.
Common Two-Letter Words:
- of, to, in, is, it, as, he, be, by, on, or, at
Common Three-Letter Words:
- and, the, for, his, not, but, you, are, her, had
- Hint: In our example, GPQ appears twice and likely represents a short word like how or can.
Step 3: Spot Repeating Letter Patterns
Only a few letters double up in English (e.g., LL in all, MM in common).
- Example: A word like SZZ probably decodes to all.
Step 4: Leverage Digraphs (Letter Pairs)
Digraphs like TH, HE, AN, IN are frequent. Spotting these can unlock multiple words.
- Example: YG in Ygua likely translates to TH (e.g., this).
Step 5: Target Unusual Letters
Rare letters (e.g., X, Q, Z) often map to specific words. For instance, X might stand for A in a word like xylophone.
Step 6: Watch for Non-Transposed Letters
Sometimes letters aren’t substituted (e.g., GLL = all). Don’t overcomplicate!
Step 7: Recognize Common Phrases
Many cryptograms start with predictable phrases like "The best..." or "Some of the...". Use these as shortcuts.
Cracking the Example Cryptogram
Applying these steps reveals the substitution cipher:
| 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 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| S | V | X | F | R | D | H | G | U | K | J | Z | N | M | P | O | W | E | A | Y | I | B | Q | C | T | L |
