Cryptle #64 · Thu 5 Nov 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 Hill Cipher, and the key is key HUNT. 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.

Need a nudge?

Letters go in pairs through a 2×2 matrix built from HUNT, read row by row with A=0. Invert the matrix (mod 26) and multiply back. A trailing X is padding.

The answer

SOLVE SEVEN DAYS AND EARN CREDIT

How it works

The alphabet sits in a square, and every letter is described by where it lives. Get the square right and the rest is bookkeeping. This one is Hill Cipher. The key: key HUNT. Letters go in pairs through a 2×2 matrix built from HUNT, read row by row with A=0. Invert the matrix (mod 26) and multiply back. A trailing X is padding. Look the first pieces up in the square and they come out S O L. The answer was SOLVE SEVEN DAYS AND EARN CREDIT.
