Daily Cryptogram
Crack the code to reveal a famous quote. Every letter has been swapped for another — figure out the substitution and decode the whole message. A new puzzle every day!
How to Play the Cryptogram
A cryptogram hides a famous quote behind a substitution cipher: every letter in the original quote has been consistently replaced with a different letter. The small letter printed beneath each box is the encrypted (cipher) letter; the empty box above it is where you type the real letter you think it represents.
Because every occurrence of a cipher letter stands for the same real letter, typing one guess fills in every matching box across the whole quote at once. Work through the puzzle by making deductions until the full sentence appears.
Use Check to flash any wrong letters, Hint to reveal one correct letter, and Reveal to see the full solution. An amber box warns you that you have assigned the same real letter to two different cipher letters.
Tips & Strategy
Attack the short words first. A one-letter word is almost certainly “A” or “I.” Two-letter words are usually “OF,” “TO,” “IN,” “IS,” or “IT.” These give you free letters to spread across the rest of the puzzle.
Hunt for THE. The most common three-letter word in English is “THE.” If you spot a repeated three-letter block, testing it as THE often unlocks the puzzle.
Use letter frequency. In English, E, T, A, O, I, and N are the most common letters. The cipher letters that appear most often are likely to be these.
Watch the apostrophes. A letter right after an apostrophe is usually S, T, or D (as in “IT’S,” “DON’T,” or “WE’D”), which are powerful clues.
What Makes Our Cryptogram Special
Every daily Cryptogram features a genuine, hand-picked famous quote encrypted with a true derangement cipher — no letter is ever left standing for itself, exactly as serious cryptogram setters demand. That small detail makes the logic cleaner and the deductions fairer.
The puzzle is completely free with no daily limits, no account, and no interruptions. Everyone gets the same quote and cipher each day, and you can replay any previous day using the date navigation arrows.
Everything runs in your browser, so the puzzle loads instantly and your solving stays completely private. Helpful touches like conflict warnings, one-letter hints, and an answer check make it welcoming for beginners while staying satisfying for veterans.
The History of the Cryptogram
Substitution ciphers are ancient. The Roman general Julius Caesar famously shifted each letter of his military messages by a fixed number of places — a scheme still known today as the “Caesar cipher.” For centuries, such ciphers were tools of statecraft, espionage, and war.
Cryptograms became a popular pastime in the 19th century. Edgar Allan Poe fuelled the craze with his 1843 story The Gold-Bug, in which a substitution cipher leads to buried treasure, and he challenged readers of a Philadelphia newspaper to send him ciphers he would solve.
In the 20th century the cryptogram found a permanent home on newspaper puzzle pages, often called the “Cryptoquote” or “Cryptoquip.” Our version carries that tradition into the browser with a fresh, fairly-constructed puzzle every single day.
Frequently Asked Questions
What is a cryptogram?+
A cryptogram is a short piece of text — usually a famous quote — encrypted with a simple substitution cipher. Every letter of the alphabet is consistently replaced by a different letter, and your job is to work out the original message.
How do I solve it?+
Click any letter cell and type the real letter you think it stands for. Because the same cipher letter always represents the same real letter, your guess fills in every matching cell at once. Keep making deductions until the whole quote is revealed.
Any tips for beginners?+
Start with short words. A single-letter word is almost always “A” or “I.” Common three-letter words like “THE” and “AND” are great footholds, and looking for apostrophes (as in “IT’S” or “DON’T”) narrows things down fast. Letter frequency helps too — E, T, A, and O are the most common letters in English.
Does a letter ever stand for itself?+
No. Our cipher is a derangement, meaning no letter is ever encrypted as itself. If you see the letter “M” in the puzzle, you know the real letter behind it is definitely not “M.”
What do the colours mean?+
An amber cell warns that you have used the same real letter for two different cipher letters — a conflict, since each cipher letter must map to a unique real letter. Press Check to briefly flash any incorrect letters red, or use Hint to reveal one correct letter.
Is there a new puzzle every day?+
Yes! A new cryptogram is generated every day and everyone gets the same quote and cipher. You can also replay previous days with the arrow buttons above the puzzle.
