Pigpen Cipher — turn any message into a secret code
Want to write a message that only your friends can read? The Pigpen cipher, also known as the Freemason's cipher, replaces every letter with a geometric symbol. It has been used for centuries in secret notes, puzzle hunts and escape rooms — and now you can create and crack Pigpen codes in seconds.
