Cryptogram Tips: How to Crack the Code, Counted

How to solve cryptograms: start with one-letter words and THE, read the apostrophes, count the code letters, spot repeated words and patterns, and say it aloud.

A cryptogram looks like nonsense at first: a familiar saying with every letter swapped for another. But the code always keeps the shape of the words, and the shape gives a lot away. To find out what gives the code away most often in our puzzles, we counted: we went through all 148 proverbs our Cryptogram uses, and through a thousand of its puzzles at each level. Here's what we found, and how to use it.

How our cryptograms work

Each puzzle is a well-known proverb, like "A stitch in time saves nine." Every letter is replaced by a code letter, the same one every time it appears, so if K stands for E once, it stands for E everywhere. Spaces and punctuation stay as they are, and no letter ever stands for itself. Each letter of the alphabet has its own code letter, so two different code letters never stand for the same letter.

On Easy, about 5 of the saying's letters are filled in to start; on Medium, about 2; and on Hard, none, with longer sayings to make up for it.

What we counted

Puzzles where it's E, T, O or A85 in 100
Share of all letters that are E, T, O or Aabout 4 in 10

Sayings that use a word twiceabout 1 in 3
Sayings with a double letter, like the LL in WILLabout 4 in 10

1. Start with the short words

Short words have only a few possibilities, so they're the quickest to crack.

2. Look at the apostrophes

An apostrophe is a gift. In our sayings, the letter after it is a T 20 times (DON'T, CAN'T, WASN'T), an S 12 times (THERE'S, IT'S, WHAT'S) and RE just once (YOU'RE). Every one of those T's comes after an N, so when a word ends in 'T, one guess gives you two letters: N and T.

3. Count the code letters

E is the most common letter in English, and it's the same in our sayings: about 1 letter in 8 is an E. In about half of our puzzles, the code letter that appears most often stands for E. In 85 puzzles in 100, it stands for E, T, O or A. Those four letters alone make up about 4 in 10 of all the letters, so getting them right fills in a good part of the saying.

E also likes the ends of words: more than 1 word in 5 in our sayings ends in E, and nearly as many end in S. T is the most common first letter, helped along by THE, THAN, THERE and TIME.

4. Look for patterns and repeats

The code keeps a word's pattern, and patterns narrow things down quickly.

A worked example

Here's one of our proverbs, in code, step by step.

The puzzle: seven words in code. A one-letter word appears twice, and so does a six-letter word with an apostrophe.

The one-letter word must be A. The six-letter word appears twice, and the letter after its apostrophe is S or T. Look closely at it: its third and fifth code letters are the same. A T would need an N in front of the apostrophe, which would make the word _ _ N _ N'T, and no word looks like that. So it's S.

A and S filled in. The repeated word is now five letters, then 'S.

Now look at the shapes. The five letters before 'S have the same letter in the third and fifth places, and the first word of the saying ends in the same four code letters. Two five-letter words that end the same way and differ only at the start: WHERE and THERE.

W, H, E, R and T filled in: WHERE THERE'S A W blank blank blank, THERE'S A WA blank.

From here the proverb almost says itself: "Where there's a WILL, there's a WAY." Only I, L and Y were left to find.

5. Say it aloud

All of our puzzles are proverbs, the kind passed down for generations, and a saying averages just 6 words. Once two or three words are in, read the line aloud with gaps, like "A ___ in time ___ nine." A familiar saying often jumps out, and then you can fill in the rest and check it against the code.

6. Use what can't be true

Two facts rule out wrong guesses:

7. Pick the right level, and use a hint when you're stuck

If you're new to cryptograms, start on Easy, where about 5 of the 13 or so letters are already in: often enough to read a word or two straight away. Medium gives you about 2, and Hard gives you none, but its sayings are longer, about 29 letters, so there's more to count.

When you're stuck, Hint fills in the right letter for the code letter you've chosen, or, if you haven't chosen one (or it's right already), for the most common code letter that isn't right yet. One good letter is often all it takes.

Solving on paper

If you do cryptograms from a newspaper or a puzzle book, write the alphabet across the bottom of the page and fill in the code letter under each letter as you find it. Cross letters off as you use them, and write lightly in pencil, so a wrong guess rubs out cleanly. Our printable cryptograms put sayings in large print, usually three to a Letter page, with squares to write in and an answer key, at Easy, Medium and Hard.
