About this game

Every great quote is hiding in plain sight. Decipher turns more than 700 famous quotes, historic sayings and philosophical aphorisms into cryptogram puzzles, and your job is to crack the cipher and reveal the words.

A cryptogram is a classic newspaper-style cipher puzzle. Each letter of the quote has been swapped for a different one, and the same swap is used all the way through. Spot a pattern, make a guess, and watch the whole sentence start to take shape.

HOW IT WORKS
- Tap a cipher letter, then tap a letter on the keyboard.
- Every matching cipher letter in the quote fills in instantly.
- Punctuation and spaces are already shown, so you can focus on the code.
- If a letter is already in use, it simply moves to the new box and you are told about it.
- Solve the puzzle to unlock the full quote, its author and a short note about who they were.

WHAT YOU GET
- 700+ quotes across Philosophy, Literature, History, Science and Wisdom
- Easy, Medium and Hard levels, from short proverbs to long passages
- Daily Cipher: a new puzzle every day, with a streak to keep going
- A custom in-game keyboard that shows which letters are unused, placed or locked in as correct
- Three kinds of help when you are stuck: Reveal Letter, Check Errors and Author Hint
- Your time and hint count saved for every puzzle, with your best time kept
- Your progress is saved automatically, so you can pick up where you left off
- Parchment (light) and Slate (night) themes with an easy-to-read serif typeface
- Optional sound and haptic feedback, and a choice of QWERTY or alphabetical keyboard

PLAY ANYWHERE, EVEN OFFLINE
All puzzles are built into the app. There is no account, no sign-in and no internet needed to play. Take your cryptograms on a flight, a commute or a quiet afternoon.

MADE FOR PUZZLE LOVERS
If you enjoy crosswords, logic puzzles, word games or a good brain teaser, you will feel at home. Decipher is calm, unhurried and made for long, relaxed sessions. Solve a quick Easy quote over coffee, or settle in with a Hard one.

ABOUT ADS
Decipher is free to play and supported by ads. Some hints can be unlocked by watching a short optional video. In regions where it is required, you will be asked for your privacy choices on first launch, and you can review them at any time in Settings.
