    About puzzle #9

    Puzzle #9 is the one for Sunday 11 October 2026: the Sunday cryptogram, the hardest of the week. Every letter is swapped for another, the same way all through. Short words, repeated patterns and letter frequency are the way in.

    Stuck? The Cryptogram decoder is fair to use, and Hint fills in one letter at a time. A new puzzle opens every day at midnight where you are, at StringMash Daily, and every earlier one is in the archive under the puzzle.
