Today's Cryptoquip Clue, Explained
Written and checked by hand. Last reviewed July 25, 2026.
Underneath a printed Cryptoquip, most papers run a line like Today's Cryptoquip clue: D equals C. It is not decoration and it is not a hint about the subject matter. It is one cell of the answer key, handed to you before you start, and used properly it is worth a great deal more than the single letter it looks like.
What it literally means
The letter on the left is a cipher letter — one of the letters actually printed in the puzzle. The letter on the right is what it stands for. So D equals C means: everywhere you see a D in the puzzle, write a C above it.
That direction is the one people get wrong. The clue reads in the same direction as the puzzle: from what is printed, to what it means. If you apply it and the puzzle immediately produces impossible words, try it the other way round before you conclude the paper made a mistake.
Why it is worth more than one letter
A single substitution looks like a small gift, but a cryptogram key is a one-to-one pairing, so every pairing you fix eliminates possibilities everywhere else. From D equals C you immediately know three things:
- Every printed D is a C. Fill them all in at once, across the whole puzzle.
- No other cipher letter can be C. C is spoken for. If you were considering C for some other letter, cross it off.
- D itself cannot be anything else. Any half-formed theory about D is now dead.
There is a fourth thing, and it is the one experienced solvers use. C is not a common letter. If the clue hands you a rare or mid-frequency letter, it is usually because that letter sits inside the pun — the setter is helping you at the point where the wordplay would otherwise trap you. A clue involving Q, X, Z, K or J is nearly always pointing straight at the joke.
How to use it in practice
The efficient order, assuming a clue is printed:
- Apply the clue everywhere first, before you look at anything else. Ten seconds, and it changes the shape of the whole puzzle.
- Then find the short words. If the clue letter appears inside a two or three-letter word, start there: you already have a third or a half of it.
- Then count letters as usual. Remember that one common letter may now be excluded from the running, which sharpens the count rather than blunting it.
- Save the last word for last. In a Cryptoquip the final word is where the pun lands, and it will not be guessable from sense. Get every other letter first and let the last word assemble itself.
The rest of the method — frequency, apostrophes, doubled letters, trigrams — is the same as for any cryptogram, and it is set out step by step in our guide to solving cryptograms.
Why we do not print a clue on the daily puzzle
Our daily is a quotation rather than a pun, and quotations do not need the compensation. Sentence structure, articles and prepositions give you footholds that a joke deliberately withholds. Printing a clue would remove the first and most satisfying move of the puzzle rather than the last and most frustrating one.
The rules our puzzles do follow, including the guarantee that no letter ever stands for itself, are on the cryptogram rules page. That guarantee is itself a standing clue: it eliminates one candidate for every cell in the puzzle, every day, for free.
If you are holding a puzzle right now
We do not publish answers to the syndicated Cryptoquip. That puzzle belongs to King Features Syndicate, and reprinting its solutions would be reprinting their work. What we can do is give you a tool that solves the one in front of you without anyone having to publish anything.
The Cryptoquip solver takes the cipher text and the printed clue, runs the search in your browser, and shows you the substitution it found. Nothing is uploaded and nothing is stored. If you would rather learn the technique than get the answer, work through the method instead — it is the same puzzle either way.
A note on those "clue letter" pages you may have found
Search for a specific clue such as cryptoquip J equals G and you will turn up pages built for every one of the six hundred and seventy-six possible pairings, none of which say anything the others do not. We have deliberately written one page instead of six hundred, because a clue pairing carries no information away from the puzzle it was printed under. This is that one page.
Questions we get
Which letter is the cipher one, the first or the second?
The first. In "D equals C", D is what is printed in the puzzle and C is what it really means. If your first attempt produces nonsense, you have almost certainly read it backwards; swapping the two takes five seconds to test.
Does the clue letter change every day?
Yes, and so does the whole key. Nothing about yesterday's clue applies today.
Why does the Cryptoquote not get a clue letter?
Because it does not need one. A quotation is ordinary prose, so grammar gives you footholds. A pun is written to frustrate exactly that, so the clue is compensation.
Is there a list of what each clue letter means?
No, and any page claiming to have one is selling you nothing. There are six hundred and seventy-six possible clue pairings and the pairing tells you nothing on its own — its whole value is in the specific puzzle it was printed under.
Can I use the clue in your solver?
Yes. There is a field for it. Entering the clue narrows the search before it starts, so the answer comes back faster and with fewer alternatives to sift.
