Cryptograms are captivating puzzles that have intrigued minds for centuries. Cryptograms, commonly encrypted with single-transposition keys, appear as an indecipherable sequence of characters:

However, there are systematic methods to decipher these cryptograms by understanding the conventions of the English language and making calculated guesses. Uncover the mystery behind cryptograms and learn how to solve them with our intuitive, detailed guide.

Mastering Cryptograms: A Comprehensive Guide to Decoding

Step 1: Understand the Basics

A cryptogram is a type of puzzle that consists of a short piece of encrypted text. The most common form of cryptogram is the substitution cryptogram, where each letter in the original text is replaced with a different letter.

Step 2: Identifying Letter Frequencies

In the English language, certain letters appear more frequently. The letter ‘E’, for example, is the most commonly used letter. Comparing the frequency of letters in the cryptogram to the frequency of letters in the English language can give you hints about the substitutions.

Step 3: Look for Single-Letter Words

In English, the only single-letter words are ‘I’ and ‘A’. So, any single-letter word in the cryptogram is likely to be either ‘I’ or ‘A’.

Step 4: Spot Common Letters and Patterns

Look for common short words or patterns. Words like ‘the’, ‘and’, ‘of’, ‘is’, ‘it’ are very common in English. If you can spot these, it will give you a lot of information about which letters might correspond to which.

Step 5: Make Educated Guesses

Once you’ve identified a few letters, you can start to make educated guesses about what the rest of the words might be. This will often allow you to identify more letters, and the puzzle will start to unravel.

Step 6: Keep Trying

Sometimes, you might guess wrong. That’s okay! Just keep trying different possibilities, and eventually, you’ll crack the code.

Additional Tips

  • Popular Letters: Start by identifying the most frequently used letters in English, namely E, T, A, O, N, I, and S. In the cryptogram, the most frequently occurring letters are likely these. For instance, in the cryptogram above, M, R, and S appear multiple times. Substituting these with common English letters is a good starting point.
  • Short Words: Decoding short words can aid in solving longer cryptogram sentences. Words of two or three letters are particularly helpful. The most common two-letter words include ‘of’, ‘to’, ‘in’, ‘is’, ‘it’, ‘as’, ‘he’, ‘be’, ‘by’, ‘on’, ‘or’, ‘at’. The most common three-letter words are ‘and’, ‘the’, ‘for’, ‘his’, ‘not’, ‘but’, ‘you’, ‘are’, ‘her’, ‘had’. In the cryptogram example, the three-letter words ‘GPQ’ occur twice, translating to ‘can’ and ‘how’.
  • Repeated Letters: The English language has certain linguistic patterns that can serve as clues. For example, few letters are repeated consecutively in a word: RR, LL, NN, MM. If a three-letter word has repeating letters, like SZZ, it’s likely the word ‘all’.
  • Common Patterns and Digraphs: The letters ‘TH’ occur frequently in words like ‘the’, ‘that’, ‘this’, ‘those’, ‘them’. Two-letter combinations commonly appearing in English, known as digraphs, can be useful. Common digraphs include ‘TH’, ‘HE’, ‘AN’, ‘IN’, ‘ER’, ‘RE’, ‘ES’, ‘ON’, ‘EA’, ‘TI’.
  • Unusual Words: Words that are unusual or start with uncommon letters, like ‘X’, can provide an edge in solving cryptograms.
  • Obvious Conventions: Cryptograms often include non-transposed letters, so the word ‘all’ may be encoded as ‘GLL’. Cryptograms frequently start with phrases like “The best…”, “Some of the…”, or “The only…”, providing a starting point for decoding.
  • Pattern Recognition: The process involves making systematic educated guesses until a pattern emerges. Once vowels are identified, solving the rest of the puzzle becomes easier.
  • Possible Errors: Cryptograms may have errors, whether grammatical, spelling, or encoding. These can serve as additional challenges to solve.

Examples

Now that you have a method to tackle cryptograms, let’s look at a couple of examples.

Example 1: N WNAHJ KNAJ WJZZ JA

Using the steps above, you can conclude that ‘N’ corresponds to ‘I’, ‘W’ to ‘A’, ‘A’ to ‘M’, ‘H’ to ‘N’, ‘J’ to ‘D’, ‘K’ to ‘T’, and ‘Z’ to ‘S’. The decoded message is: “I AM THE BEST IS”.

Example 2: HVS DFWSF OG WIFOZOH

Conclusion

By applying the same steps, you can decipher ‘H’ to ‘T’, ‘V’ to ‘H’, ‘S’ to ‘E’, ‘D’ to ‘A’, ‘F’ to ‘R’, ‘W’ to ‘O’, ‘O’ to ‘F’, ‘G’ to ‘L’, ‘Z’ to ‘U’, and ‘I’ to ‘S’. The decoded message is: “THE ART OF FULFILL”.

Decoding the Cryptogram: Using these step-by-step processes, you can decipher the cryptogram at the beginning of the article. The substitution cipher used is:

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

Thus, the decoded cryptogram reads: “This is how anyone can learn how to solve cryptograms.“

Solving cryptograms is a great way to stretch your brain and play with language. With practice, you’ll start to spot patterns and make connections more quickly. So grab a cryptogram and start decoding! Remember, the journey of solving cryptograms is all about trial and error, logical thinking, and persistence. Happy decoding!
