Substitution Ciphers

Pigpen Cipher

Substitution ciphers do not just use letters or numbers. Some, such as the pigpen cipher, use symbols. Here is our message I AM A CODEBREAKER written using the pigpen cipher:

pigpen - i am a codebreaker

Although the pigpen cipher looks unintelligible, it is actually a fairly basic form of the substitution cipher. The letters of the alphabet are written out on 4 grids.

pigpen - i am a codebreaker

To write your code, take the portion of the grid in which the letter you require is written. This then becomes your code!
