Decode the quote
A daily cryptogram and code-cracking puzzle: crack a new hidden quote every day. No spoilers, no signup — just you and the cipher.
A new puzzle unlocks daily at local midnight on your device — no account, no signup, and nothing to install. Progress and stats are saved locally in your browser, not on a server.
How to play
- Every number stands in for one letter — always the same letter, everywhere.
- Fill in a number once, and every matching number fills in too.
- No punctuation is shown — just bare letters to decode.
- You have 5 guesses to reveal the whole quote — a guess is only spent when you submit the full thing, so filling in letters is free.

About Quipher
Quipher's a gamified version of the classic substitution cipher, dressed up as a code-cracking game. Each letter in the quote's swapped for a number, and you decrypt it by guessing letter by letter. The classic version of this puzzle is called a cryptogram - you'll sometimes find them in old newspapers under names like cryptoquote or cryptoquip.

There's a new quote every day - I've tried to find interesting and novel quotes from people throughout history, so once solved I hope you find those interesting too!
Quipher FAQ
How many guesses do I get?
Five. A guess is only spent when you submit the whole quote, so filling letters in and correcting them as you go is free — it's only hitting submit with the quote still wrong that costs you one.
Is punctuation shown in the puzzle?
No — the grid only shows bare letters to decode. The original casing and punctuation come back in the reveal, once you've solved it or run out of guesses.
Can two different numbers stand for the same letter?
No — it's a strict one-to-one substitution, so each letter maps to exactly one number and each number maps to exactly one letter. That's why solving one instance of a number solves every instance of it.
Where do the quotes come from?
I've hand-picked them from people throughout history, trying to keep them varied and genuinely worth reading once decoded, rather than filler.
What happens if I run out of guesses?
The full quote and author are revealed, the day counts as a loss in your stats, and a new quote is waiting for you tomorrow.
