Eliminations by Category
Eliminations organized by cipher type. Each record says what was tested. Most also give a command to rerun the test yourself; fewer record a best score or list what the result does not rule out.
Bespoke
Non-standard methods inspired by the physical sculpture or military cipher systems. These approaches don't fit neatly into classical categories. Includes DRYAD charts, Morse code analysis, and coordinate-based approaches.
Fractionation
Methods that break each letter into smaller pieces (like grid coordinates), scramble those pieces, then reassemble them into new letters. Includes Bifid, Playfair, Four-Square, and ADFGVX.
Key Models
Different ways to generate the secret key: from a passage in a book, from a date, from a mathematical formula, or from the sculpture itself. Includes running keys, self-keying (autokey) ciphers, and keyword-derived approaches.
Multi Layer
Combined approaches that stack multiple encryption steps. For example, replacing letters first, then scrambling their order. Includes filler-letter removal, cascaded layers, and joint optimization.
Substitution
Methods that replace each letter with a different letter using a key or pattern, like a secret alphabet. Includes Vigenère, Beaufort, Quagmire, Hill, and more.
Transposition
Methods that scramble the order of letters without changing them, like writing a message into a grid and reading it back in a different order. Includes columnar, rail fence, route, and grille ciphers.
