Betamaze (maze alphabet)
Betamaze is a maze alphabet created in the United States by Terrana Cliff and first published on Omniglot, before spreading through the cryptopuzzle community (dCode, Cipher Tools). Visual quirk: each character occupies a square built from black squares and triangles whose openings trace a maze fragment. Fragments link up when glyphs are placed side-by-side, giving ciphertext the appearance of a continuous maze on the page.
Contrary to what is often written, the effect is not merely decorative: the alphabet is designed to draw actual mazes, with paths that branch, come together, terminate or open out. That dimension — widely under-used — is what makes Betamaze a puzzle medium rather than a typeface in disguise. It shows up on logic puzzle sites, in paper escape rooms, and in fan-con riddles. 26 Latin letters + 10 digits (0-9) + 7 marks (space, comma, full stop, colon, semicolon, quote, parenthesis).
How does the alphabet work?
The cipher relies on a monoalphabetic substitution: each cleartext character (letter, digit or mark) is replaced by a fixed Betamaze glyph. Same mechanic as the Caesar cipher (~50 BC), except the “key” is not a shift but a table of maze fragments.
The table holds 43 glyphs: 26 for Latin letters, 10 for digits and 7 for punctuation. Each glyph is a square whose openings draw a unique pattern; the patterns are designed to chain into a continuous path. Depending on the letter, a cell can open a 3-way junction, a 2-way passage, a 90° turn, a dead end closed on all sides, or a cell open in all four directions.
Cryptographic strength: low. Like any monoalphabetic substitution, frequency analysis breaks it in a few dozen words. Betamaze is valued for its graphic look and for the trail it can hide: a ciphertext resembles a dungeon map, which works very well in an escape room or a gamebook.
Rotations, flips and real mazes
The key point, usually missed: every glyph can be rotated or flipped without changing its meaning. Since all the shapes are unique, no rotation creates ambiguity — unlike the Latin alphabet, where a flipped b becomes a d.
That freedom of orientation is the heart of the system:
- it lets you steer the path of the maze, so a grid can be composed with genuine entrances, exits and branches;
- it allows filler: in a coded message, the bulk of the grid can be junk, with only the walkable path carrying the real message;
- it deliberately complicates both encoding and decoding: finding the path is part of the puzzle.
In the workshop: rotation is available. On the encryption side, click a glyph in the image panel to turn it a quarter turn; on the decryption side, the picker offers a Rotate the glyphs button that turns the whole chart, so you can match the glyph as it appears on your document. The chosen orientation carries over as-is into the PDF export. Flipping (mirroring) is not exposed yet.
Historical and modern usage
- Omniglot — first publication of the alphabet, reference chart.
- Online cryptopuzzles — dCode, fan-con riddles, r/codes community.
- Paper escape rooms — the maze grid acts as a visual clue… and as a route to follow.
- Gamebooks — popular with kids’ publishers for its decorative look.
- Graphic design — experimental typography and poster lettering.

What are the weaknesses?
- Monoalphabetic substitution — frequency analysis is immediate.
- No polyalphabetism — no key, so nothing to guess beyond the table.
- Public table — available on Omniglot, dCode and Gumroad.
- The maze isn’t encryption — playing with rotations and filler adds a layer of riddle (where does the path start?), not real security.

The parenthesis glyph serves as both opening and closing bracket: just flip it.
