Cryptogram Tips: Read the Word Shapes Before You Guess a Letter (2026)

1. What is already on the board

A cryptogram is a quotation in a one-to-one letter substitution, and the only thing separating you from it is a mapping table. Before you press anything, four things are already true of the board in front of you.

Only the letters that occur are shown. The board does not carry 26 cipher letters; it carries the ones the quotation actually uses — 9 to 16 in an easy puzzle, 10 to 20 in medium, 12 to 17 in hard. So the job is never "map the alphabet". It is filling 9 to 16 slots, minus the ones handed to you.

The givens are the frequent ones. The build reveals a cipher letter only after ranking the puzzle's letters by how often they appear, so the letters you get are the ones that cover the most cells. In the easy tier the three given letters cover 7 to 11 of the puzzle's cells — roughly a third to well over half of the board's letters are correct before your first tap. Medium starts you at 5 to 12 cells, hard at 3 to 10.

No letter stands for itself. Every key in the book is fixed-point-free: E never encodes as E. That is one candidate removed from 26 before you start, and it is a free test for any hypothesis — if your guess has a cipher letter meaning itself, the guess is wrong.

There is no punctuation to lean on. The 36 quotations are proverbs and pre-1900 lines with no commas, no full stops, no apostrophes and no quotation marks. The only structure is the space, which means word boundaries are real and everything else has to come from letters.

2. Read the word lengths before you read the letters

Word lengths are the strongest single handle in this book, and they are free: the board shows every word's length before a single letter is filled.

The 36 quotations have 36 distinct word-length signatures. No two puzzles share the same sequence of word lengths. That is worth knowing for two reasons. First, it means the shape on your screen narrows the field immediately — a six-word line laid out 1-7-5-7-2-4 cannot be confused with any other line in the book. Second, it means you can use recognition honestly: if the length pattern reminds you of a proverb, the board will confirm or destroy the guess in a few taps, and you are not guessing at the mapping at all, you are testing a whole ciphertext at once.

Inside a puzzle, not all words are equally useful:

• A three-letter word is nearly worthless as an anchor. Most puzzles have several, and THE, NOT, WAS, HAS, YOU and DAY all have three different letters.
• A two-letter word is worth a lot, and section 5 shows why the field is smaller here than in normal English.
• A word of seven letters or more is the best anchor in the book: there are 29 such words across 21 of the 36 puzzles, and a long word has enough internal structure to kill most wrong theories on sight.

3. The given letters tell you which letters are frequent

Because the build reveals by frequency, the givens are a frequency report you did not have to compute. Across the easy tier's 36 given letters, the plain letters are distributed like this:

Medium hands out 24 letters, led by E nine times and T five times; hard hands out 12, led by T three and N three. In plain terms: your starting letters are almost always drawn from E, T, O, A, S, N, L, I and R. That is the ETAOIN set, already paid for.

The practical consequence is that the classic "count letters and guess E" routine adds less here than in a newspaper cryptogram. You have not been given a random letter; you have been given the answer to the frequency question, and the remaining work is placing letters against word shapes.

4. Frequency is a tiebreaker, not a plan

Here is the whole corpus counted out — 1,086 letters of public-domain proverbs and pre-1900 authors:

E 137, T 116, O 97, A 82, N 81, S 80, I 79, R 61, H 58, L 45, D 34, W 34, U 25, B 24, G 23, C 20, Y 18, M 17, P 14, K 13, F 13, V 9, X 3, J 2, Q 1. Z never appears.

That ordering looks like textbook ETAOIN and invites the obvious move: assume the most frequent cipher letter is E. Checked against all 36 puzzles, that assumption is right 13 times out of 36. The most frequent cipher letter is E in 13 puzzles, O in 6, T in 4, S/A/N in 3 each, I in 2, and L or H in 1 each.

So keep frequency, but demote it. It is a tiebreaker between two letters that word shapes cannot separate, not a first move. The board's own givens already tell you the frequent letters, and the shapes tell you where they can go.

One more corpus fact worth carrying: Z is absent from all 36 quotations, so no cipher letter in this book ever decodes to Z. Along with the no-self-mapping rule, that trims the candidate space for every slot to 25 before any reasoning starts.

5. One-letter and two-letter words: the two smallest anchors

One-letter words. There are 13 one-letter words in the corpus, spread over 10 of the 36 puzzles, and every single one of them is A. There is no I anywhere in the 36 quotations. So a one-letter word in this game is not the classic "A or I" guess — it is a free A, given to you by the board. Puzzle 1 (A ROLLING STONE GATHERS NO MOSS), puzzle 7, puzzle 12, puzzles 21 and 22 (two each), 26, 29 (two), 30, 32 and 36 all hand you this anchor.

Two-letter words. There are 59 two-letter words, in 27 of the 36 puzzles, and they draw on a vocabulary of exactly 13 words:

AN · BE · DO · IN · IS · IT · NO · OF · ON · OR · SO · TO · WE

No two-letter word in the book is a doubled letter (OO, EE), so the first and second letters of a two-letter word are always different — that halves the field again in practice. Measured against that 13-word list: with neither letter known a two-letter slot has 13 candidates; knowing one letter cuts it to an average of 2.32 candidates (first position) or 1.92 (second position); knowing both pins it.

The usable rule: do not spend a two-letter word as a guess, spend it as a confirmation. Fill the 7+ letter word first, then check whether the two-letter slot agrees with the letters you just placed. IN, IT and IS differ by one letter, and committing to IS before the second letter is fixed is the most common way to lose a minute.

6. Doubles and repeated shapes

A doubled letter is the cheapest test in the game. 28 words across 18 of the 36 puzzles contain a repeated letter: ROLLING, MOSS, ALL, GLITTERS, LOOK, BETTER, NEVER, TOO, COOKS, THAT and the rest. Once you think a word is COOKS, the two O positions must carry the same plain letter — one glance confirms or kills the theory, no guessing.

The rarer shape is a word whose first and last letters are the same, and it is rarer than you would guess: only 6 words in the entire corpus do it — THAT (puzzles 2 and 25), STARS (27), HATH (30), ENTIRE (31) and EXCELLENCE (32). When a word on your board has identical first and last cipher letters and is longer than two letters, it is one of those shapes, and that is a very small set of candidates.

Section 9 uses both shapes as the entry point for each of the twelve easy puzzles.

7. Which letter to fill first

The build's cells-per-letter average tells you what one correct assignment is worth: 1.77 cells in easy, 2.14 in medium, 2.69 in hard. Hard puzzles pay more per letter, but they hand you less (11-24% of cells given) and each board carries 12-17 cipher letters, so the order in which you work matters more there.

A working order that holds up across all three tiers:

1. Place the given letters. They are already right; do not fight them.
2. Take the smallest anchored word — a one-letter word first, then a two-letter word whose partner letter you already know.
3. Grow from an anchored word into a long word. A 7+ letter word that shares one letter with something you have placed is the strongest next step.
4. Use doubles to test, not to guess. If a doubled slot disagrees with your theory, drop the theory.
5. Leave frequency for last — for the two letters word shapes cannot separate.

One mechanic matters for strategy: a plain letter can only belong to one cipher letter, so assigning a letter that is already in use moves it rather than duplicating it. That is the right behaviour, but it also means a careless correction can quietly erase work on another word. Check the toast message — it names the cipher letter it moved the letter away from.

8. Hints reveal in alphabetical order, so aim them

Hints are unlimited and counted. What the build does with one is specific: it locks the selected cipher letter if that letter is still wrong or empty; if nothing usable is selected, it walks the puzzle's cipher letters in alphabetical order and takes the first one still unsolved.

The alphabetical walk is the part worth knowing. Puzzle 1's hints, pressed from a clean board with nothing selected, reveal in this order: A→R, B→T, C→I, E→L, L→E, N→H, P→A, Q→G, W→M. That is cipher-alphabetical, not usefulness-ordered — the build does not hand you the most informative letter, it hands you the next letter in the alphabet.

Two consequences:

• Select the letter you are stuck on before pressing Hint. You get that letter, not whatever the book thinks is next.
• The hack-free ceiling is small. If you never reason at all, finishing costs distinct letters − given letters hints: 6-13 in easy, 8-18 in medium, 11-16 in hard. Those are the numbers to beat, not a prohibition — a hint is a tool, and a puzzle solved with two hints still counts as solved.

Hints also cost you the record. Your best time for a tier is only recorded when the puzzle is solved with zero hints, and the win panel shows the hint count next to the time. The streak counter is separate: solving increments it, pressing New puzzle or switching tier without solving resets it, and Play again keeps it.

9. The twelve easy lines, one entry point each

Each row below is the shortest honest way into that puzzle — the anchor to take before anything else. Shapes are written as position patterns, so 0122 means letters 3 and 4 are the same.

1. A ROLLING STONE GATHERS NO MOSS — 6 words, 26 letters, 12 cipher letters, 11 given cells, givens S, O, N. Start on the one-letter A, then NO; MOSS (0122) confirms the doubled S.
2. ALL THAT GLITTERS IS NOT GOLD — 24 letters, 12 cipher letters, givens T, L, O. ALL (011) gives you a doubled L immediately, and THAT (0120) means positions 1 and 4 carry the same letter.
3. PRACTICE MAKES PERFECT — only 3 words, 20 letters, 11 cipher letters, givens E, C, R. PRACTICE (01234536) repeats one letter at positions 4 and 7, PERFECT (0123145) repeats one at positions 2 and 5, so the two long words give you two independent double-letter tests.
4. LOOK BEFORE YOU LEAP — 4 words, 17 letters, 9 given cells (53% of the board), givens O, E, L. LOOK (0112) is a doubled O, and LEAP/LOOK share an L, so one letter does two jobs.
5. BETTER LATE THAN NEVER — the smallest board in the book: 4 words, 19 letters, only 9 cipher letters, and the givens E, T, N already cover 11 cells. BETTER (012213) has a doubled T, NEVER (01213) repeats its second letter at the end.
6. ACTIONS SPEAK LOUDER THAN WORDS — 5 words, 27 letters, 16 cipher letters, the thinnest given coverage in the tier (9 cells, 33%). No doubles and no one-letter word, so take the 7-letter ACTIONS (0123456, every letter different) and place its given S, O and A: the four remaining slots must then be four different letters that are none of those three.
7. EVERY CLOUD HAS A SILVER LINING — 6 words, givens L, E, I, plus a one-letter A. EVERY (01023) repeats its first letter at position 3; LINING (012123) is the strongest shape on the board.
8. KNOWLEDGE IS POWER — 3 words, 16 letters, 12 cipher letters, givens E, O, W. KNOWLEDGE (012345675) is nine letters and repeats one letter at positions 6 and 9; the two-letter IS confirms once that letter is placed.
9. STRIKE WHILE THE IRON IS HOT — 6 words, givens I, H, T. Two words share the shape 012 (THE and HOT), so placing one constrains the other; WHILE and STRIKE are both six letters with no repeat.
10. TOO MANY COOKS SPOIL THE BROTH — 6 words, 25 letters, 16 cipher letters, givens O, T, S. TOO (011) and COOKS (01123) are two independent double-letter tests, and COOKS shares its doubled letter with TOO.
11. THE EARLY BIRD CATCHES THE WORM — THE appears twice, so the same three cipher letters appear in two places with the same pattern. Find one THE and you have found both; from there CATCHES (0120345) repeats its first letter at position 4, which is a free test on any theory that fills it.
12. ROME WAS NOT BUILT IN A DAY — 7 words, 21 letters, 15 cipher letters, only 7 given cells (33%) but three of the words are three letters long and one is a one-letter A. WAS, NOT and DAY all have three different letters, so A plus the two-letter IN is the real entry point.

10. Common mistakes

• Assuming the single letter is I. In this book there are 13 one-letter words and all of them are A.
• Assuming the most frequent cipher letter is E. It is E in 13 of 36 puzzles and something else in 23.
• Guessing a whole word from its length. Three-letter words are everywhere and carry almost no information; anchor on 7+ letters instead.
• Duplicating a plain letter. The board moves it instead, which silently changes another word. Watch the toast message.
• Trying to fill the whole alphabet. Only 9-20 cipher letters are on the board; the rest of the alphabet is not part of the puzzle.
• Looking for punctuation. There is none in any of the 36 quotations. The space is the only structural clue.
• Grinding a board you cannot read. Hints are unlimited and counted, not capped: 6-13 presses finish an easy board, 8-18 a medium one.
• Skipping puzzles carelessly. Pressing New puzzle without solving resets the streak; Play again does not.

FAQ

What is a cryptogram?

A quotation written with a one-to-one letter substitution. Every cipher letter stands for exactly one plain letter and stands for it everywhere in the text; no letter stands for itself. Rebuild the mapping and the quotation appears. In this build a puzzle is solved the moment every cipher letter on the board carries its true plain letter, so partially consistent mappings do not win.

How do you solve a cryptogram?

Read word lengths first, place the given letters, then anchor on the smallest word you can settle — a one-letter word, or a two-letter word whose partner letter is already known. Work outward into 7+ letter words, use doubled letters as tests, and keep frequency for the last two letters shapes cannot separate. On this book the starting givens already cover a third to more than half of an easy board's cells, so the first moves are cheaper than they look.

Is this cryptogram free to play online?

Yes. The whole game is a static page: 36 puzzles across three tiers, no download, no sign-up, no account and no network requests after the page loads. Hints are unlimited and only counted, and the timer, streak and best times are stored in your browser's local storage rather than on a server.

Do cryptograms use punctuation or apostrophes?

Newspaper cryptograms often do, and they use them as a foothold. This one does not: the 36 quotations contain 1,086 letters and no punctuation at all, so there is no apostrophe to point at a possessive and no comma to separate a clause. The only structure is the space between words, which is why word lengths carry so much of the work here.

Is there a daily cryptogram?

No. The book is fixed at 36 quotations, 12 per tier, and no new puzzle appears on a schedule — the streak counter tracks puzzles solved in a row, not consecutive days. A puzzle can be pinned or shared by adding ?n= to the URL: ?n=1 through ?n=12 are easy, 13-24 medium and 25-36 hard, out-of-range values clamp to the nearest end of the book.

How many letters do I have to work out?

Only the cipher letters that appear on the board: 9-16 in easy, 10-20 in medium, 12-17 in hard, minus the given ones. Letters the quotation never uses are not shown and never need to be assigned. Across the whole corpus 25 of the 26 letters appear, and Z appears in none of the 36 quotations.

Where can I play it?

On this site's Cryptogram page. The build is Playnesta-original under MIT: the seeded key generator, the fixed-point-free permutation, the encoder, the frequency-based reveal policy, the win test, the board, the letter keyboard, the hint accounting, the timer, the streak store and the analytics bridge are all Playnesta work, and no upstream code, artwork, audio or font is redistributed. The quotations are public domain — traditional proverbs and authors dead before 1900, each credited in the win panel. Cryptogram is a descriptive name for the puzzle form; this game is not affiliated with any newspaper, publisher or app of a similar name. Playnesta Games is the developer and publisher of this web implementation.
