You spot a two-letter word that starts with the free T. It has to be TO. You fill in the O, and suddenly an eight-letter word reads T _ _ O _ _ _ _ and your brain refuses to let it go. Five minutes later you’re muttering at a 135-year-old sentence about evidence. That’s the cryptogram effect: one right guess pays for itself everywhere the letter appears.

Every letter in the quote below has been swapped for a different letter, and the swap holds for the whole puzzle. If K means E once, it means E every time. No letter ever stands for itself. You get one letter free.

How to play

  • Tap any box and type a letter. Every box sharing that cipher letter fills in at the same time.
  • Arrow keys move between boxes; Backspace clears a letter (all copies of it).
  • The alphabet strip under the quote greys out letters you’ve already used, so you can see what’s left at a glance.
  • A guess that’s already on another cipher letter turns orange, a gentle nudge that two letters can’t share an answer.
  • Check Solution marks wrong letters in red and counts as a mistake. Reveal a Letter fills in the most common letter you haven’t cracked yet.

Stuck?

  1. Hunt the short words. One-letter words are almost always A or I. Two- and three-letter words like TO, OF, IS, THE and ONE give you a foothold fast.
  2. Follow the repeats. Three words in the second sentence each appear twice. Matching letter patterns in long words are a gift.
  3. Count. E, T, A, O, I and N are the most common letters in English, a fact Edgar Allan Poe’s hero uses in “The Gold-Bug” (1843) to crack a pirate’s cipher. Find the cipher letters that turn up most often in the quote and try those first.

The quote keeps its original 1891 British spelling, so don’t fight it when a word lands one letter off from what you expect.
