The Keyholders Vol I: Encrypted Cipher Hunt Puzzle Book for Adults (Digital Download)

THE KEYHOLDERS, VOL. I: THE APPLICATION — an encrypted cipher hunt you print at home.

Somewhere behind an unmarked door, a society of codebreakers is taking applications. This book is the test.

Twenty-four enciphered transmissions stand between the first page and the last. Break one and it hands you the key to the next; miss one and the rest stay shut. No hints you didn't earn, no skipping ahead, no filler — one great lock, and the nerve to pick it.

And for those who look closer: five hidden marks, five deeper ciphers in five different systems, a passage concealed in the pages — and ciphers worked into the covers themselves, solvable before you ever open the book.

WHAT YOU GET
- A 38-page print-ready PDF (6x9), instant download
- 24 chained Vigenere transmissions, un-skippable by design
- A full cipher tableau and a worked how-to — pencil and paper, no app required
- A spoiler-proof KEYHOLE CHECK beneath every transmission: a two-letter checksum that confirms your key is right before you commit — without ever revealing the answer, so you always know when you are on the right track but the solution is never handed to you
- Hidden layers: marks, multi-system ciphers (acrostic, pigpen, Morse, binary, Ogham) and cover ciphers
- A graded difficulty system, from Simple to Brutal
- An optional free online society: enter the codes you recover to climb the ranks and earn a Keyholder membership card

EVERY LOCK IS MACHINE-PROVEN SOLVABLE
Each cipher was verified by an automated solver before it went to print — no dead ends, no ambiguity. That is the Puzzlexity Verified promise.

GREAT FOR
Codebreakers, cryptography and cipher fans, escape-room and puzzle-hunt veterans, and anyone who loved Cicada 3301 or Journal 29.
