The Pigpen Cipher
The pigpen cipher is very unusual. When it is written, it kind of looks like doodles for a math class or geometric shapes. The pigpen cipher is based on the grid for tic-tac-toe, plus an extra "X." You place two letters in each square of the tic-tac-toe and two letters in each space around the "X". You write the code using the part of the lines that surround the letters
The letters A and B would be the same, right? Wrong. The letter to the right (B) would not only have the lines around it, but a dot too. This goes for all letters to the right.
One of best characteristics of this code is that you and your friends can arrange the letters in different areas of the tic-tac-toe plus X shapes. That way, no one else will be able to decipher your secret messages without the code that you've created.
