Highlights

COORDINATES — a Latchworks Pocket Primer. Learn one of the keeper's secret hands, then put it to work.

This is the field manual for a real codebreaking cipher: a short address points into a page's own words and names a hidden letter — changing nothing on the page. Worked one step at a time, from the legend to a final test with no answer printed.

WHAT YOU GET
- A 16-page print-ready PDF (5.5x8.5), instant download
- Graduated lessons + practice — pencil and paper, no app required
- Every mark machine-proven solvable — the Puzzlexity Verified promise
- A spoiler-proof KEYHOLE CHECK on every puzzle: a two-letter checksum that tells you whether your answer is right without ever revealing it
- Hidden bonus puzzles: a cover cipher, a cross-page ‘global’ read, a bracketing trick, and an un-keyed field test
- A ‘shape of the climb’ difficulty guide, from Simple to Hard
- An optional free society: carry the words you recover to latch.works/keyhole and climb the ranks

GREAT FOR cipher and cryptography fans, escape-room and puzzle-hunt lovers, ARG players, and anyone who liked Cicada 3301 or Journal 29.
