The Freemason's Cipher
In the 18th Century, the Freemasons needed a way to keep their records passing between lodges secret. They created the Pigpen Cipher (or Rosicrucian Cipher).
How It Works
It replaces letters with symbols based on their position in a grid. * Grid 1 (Tic-Tac-Toe): Holds A-I. * Grid 2 (Dotted Tic-Tac-Toe): Holds J-R. * X-Shape 1: Holds S-V. * X-Shape 2 (Dotted): Holds W-Z.
It gets its name because the grids look like "pens" for pigs.
Why It's Fun
It is surprisingly easy to memorize. Once you know the grid shape, you can read and write it as fluently as English. It remains the gold standard for Escape Rooms and scavenger hunts.
