A code you can break by reading
A cryptogram hides a short quotation behind a substitution cipher. Every letter of the alphabet is swapped for another, and the swap is the same throughout the puzzle. If the coded letter K stands for W once, it stands for W everywhere. Substitution ciphers like this are among the oldest kinds of code, and they are easy to crack once you know what to look for, because English has strong patterns that the cipher does not hide.
In this game, no letter ever stands for itself. A coded R is never a real R. That rule is a small but useful clue when you are choosing between two options.
Where to start
Begin with the shapes of the words, not single letters.
- One-letter words are almost always A or I.
- Apostrophes stay in place. A coded letter after an apostrophe at the end of a word is often S or T, as in IT'S or DON'T.
- Doubled letters inside a word are often LL, EE, SS, OO or TT.
- Short common words like THE, AND, FOR, ARE and THAT show up in many quotes. A three-letter word that appears more than once is a strong candidate for THE.
- Repeated patterns within a word are revealing. A four-letter coded word whose first and last letters match fits THAT well.
Letter frequency helps too. E is the most common letter in English, followed by T, A, O, I and N. The coded letter that appears most often is a good guess for E.
A worked example
Say the coded quote reads KRZZ MXHR BF QRVVRJ VYCH KRZZ FCBM. Look for patterns before anything else.
KRZZ appears twice and ends in a doubled letter. QRVVRJ has a doubled pair in the middle, and its second and fifth letters match. R also appears in KRZZ and MXHR, so R is common. That points to E. If R is E, QRVVRJ reads as blank, E, double letter, E, blank. BETTER and LETTER both fit. So V is likely T.
Now VYCH starts with T and has four different letters. THAN and THEN both fit the shape, but E is already taken by R, so it must be THAN. That means coded Y is H, coded C is A and coded H is N. With E, T, H, A and N in place, KRZZ becomes blank, E, double letter. WELL fits the quote's rhythm. The opening reads WELL DONE IS BETTER THAN WELL SAID, and every remaining letter falls into place.
Using the board well
When you type a letter into one slot, every slot with the same coded letter fills at once. So one good guess can open several words, and one bad guess spreads errors just as fast. If a guess makes a word look wrong elsewhere in the quote, change it right away.
If you use the same real letter for two different coded letters, both turn red. That is a contradiction, since each real letter comes from only one coded letter. Treat red as a prompt to rethink, not just to swap one at random. The on-screen keyboard also dims letters you have already used, which helps you see what is left.
Common mistakes:
- Forcing a word. If a guess makes another word impossible, the guess is wrong, however good it looked.
- Guessing rare letters early. Fill in common letters first. Q, X, Z and J usually fall out last, once the words around them are clear.
Moving through the levels
Difficulty sets how many letters are revealed at the start. Easy reveals five, Medium two and Hard none. The quotes come from the same pool at every level.
Easy is good for learning patterns, because five known letters make the word shapes clear. On Medium, practise finding THE and the one-letter words on your own. Hard is pure deduction: start with the most frequent coded letter and the shortest words, and build from there.
The Hint button reveals the true value of the coded letter you have selected, or a random unsolved one, and locks it. A good goal is to solve Hard puzzles without hints. When you do use one, choose a letter that appears many times, so the hint teaches you as much as possible.
