Cryptle #26 · Fri 25 Sep 2026

This one is from the archive. Play it for practice — past puzzles never count toward a streak. Today’s cipher is here.

3 guesses to crack the cipher. One cipher each day.

How to play Cryptle

The block on the page is an ordinary English sentence with a cipher laid over it. Every letter is still in there. Your job is to read it.

  • We tell you which cipher it is Today it’s Autokey, and the key is primer ANVIL. The work is the decoding, not guessing what you’re looking at.
  • Type the decoded message Capitals, spaces and punctuation are all ignored — the third stone and THETHIRDSTONE both count.
  • 3 guesses, then the day is done A wrong guess tells you whether your answer is even the right length, and which part of your method to doubt.
  • Solve it and your streak grows Miss a day, or run out of guesses, and it goes back to zero. That’s the whole prize — there’s nothing to win but the run itself.
  • A new one lands at midnight Past days stay playable in the archive, but practice never counts toward a streak.

Never solved one before? The guides walk through every cipher we use, one at a time.

Autokey

primer ANVIL

CBYMOGOGVHGKRE

Need a nudge?

The key starts as ANVIL, then the message itself takes over as the key. Decode the first letters and the rest unravels.

The answer

CODE DEADRECKON

That’s a real code. Use DEADRECKON at checkout on this month’s hunt.

How it works

This is a shift cipher whose shift keeps changing. That is why letter frequency looks flat and nothing obvious jumps out. This one is Autokey. The key: primer ANVIL. The key starts as ANVIL, then the message itself takes over as the key. Decode the first letters and the rest unravels. Line the key ANVIL up under the message and undo each letter's own shift. The opening letters come back as C O D. The answer was CODE DEADRECKON.

Next time, check your work with the Autokey Cipher.
