We read every message. To help us work out what went wrong, please include your iPhone model and your iOS version (Settings > General > About), together with what you did just before the problem appeared. The version number shown on the App Store listing is useful as well.

How to play

  1. Read the cipher. Every letter in the quote has been swapped for a different letter. Q might stand for A, and X might stand for E.
  2. Tap to assign. Tap a cipher letter, then tap the letter you think it stands for. The whole quote updates at once, everywhere that letter appears.
  3. Let the pattern work for you. If ZIT appears twice and you decide Z is T, then I is almost certainly H and T is almost certainly E. You did not guess THE — you deduced it.

The first few letters are given to you when the puzzle opens. Difficulty is set by how long the quote is, and harder puzzles hand out fewer free letters: three on Easy, two on Medium, one on Hard.

Frequently asked questions

Is there a time limit?

No. There are no timers, no countdowns, and no penalty for putting the puzzle down and coming back later. Your progress is saved automatically and restored exactly where you left it.

How many hints do I get?

Two free hints every day. They reset each day, so there is nothing to run out of permanently — if you use both today, there will be two more tomorrow.

What exactly does a hint reveal?

A hint reveals one cipher-to-letter mapping that can be proved from the letters you already have, rather than an arbitrary guess. That is why taking a hint still teaches you something about how the puzzle works instead of just handing you the answer.

Does the app work offline?

Completely. The whole quote library ships inside the app, and the daily puzzle is calculated from your device’s date. Aeroplane mode makes no difference. This version makes no network requests at all.

Do I need an account?

No. There is no sign-up, no login, no email address to enter, and no password to remember. Open the app and play.

Are there ads?

Version 1.0 has no advertising of any kind — no banners, no interstitials, nothing that plays before a puzzle opens.

Why do the free hints stated above not mention videos?

Because in this version there is no video to watch. A later version may add the option to watch a short, entirely voluntary video to earn one extra hint. It would never be required, and it would never interrupt a puzzle.

Is there a new puzzle every day?

Yes. A new quote is released at midnight in your local time. Because it is derived from the date, every player sees the same puzzle on the same day — without a server being involved.

Will I see the same puzzle twice?

Not within a year. The library holds more than 350 quotes, and the daily rotation is shuffled so that consecutive days are never adjacent in the library, and so the last puzzle of one full cycle is never the first puzzle of the next. Beyond a year, quotes do come around again.

What is in practice mode?

Practice mode gives you the entire quote library, so you can solve as many puzzles as you like instead of waiting for tomorrow. You can filter by difficulty, and solving a practice puzzle never affects your daily streak. Hints come from the same two-a-day allowance as the daily puzzle, so a practice puzzle can use up the hints you were saving for today.

Where does the text come from?

Every quote is taken verbatim from a work in the public domain, along with traditional proverbs — Austen, Dickens, Melville, Twain, Conan Doyle, Thoreau, Wilde, Carroll, Stoker, Shelley and others. Nothing is paraphrased or rewritten, the author is recorded with each quote, and the app claims no copyright over these texts.

Where is my progress stored? Will I lose it?

Entirely on your own iPhone, inside the app’s private storage. It is never uploaded anywhere. Deleting the app permanently deletes your progress and statistics. Moving to a new phone will carry your progress over only if your device backup includes app data.

How do I reset my progress or streak?

Use “Reset all progress” on the Stats screen. To erase absolutely everything at once, delete the app from your device.

I found a typo, or a quote is attributed incorrectly.

Please report it. Send the quote text and, if you can, the date it appeared, and it will be corrected in the next update.

The app is not working as expected. What should I do?

First, close the app completely and reopen it — progress is saved continuously, so nothing will be lost. If the problem continues, please email the details above, including your iPhone model and iOS version.

There is no way to reach another player, and no user content.

Correct. Cryptogram Daily is a single-player puzzle. There is no messaging, no sharing to a feed, no web browser inside the app, and no way for one user to contact another. This is why the app is rated 4+.
