Home Activity Pig Pen code
Pig Pen code layout

Also known as the Domino Code. The code is quite simple, although it looks complex.

Draw a 3 x 3 naughts and crosses (tic tac toe) grid with the alphabet arranged in the squares as shown in the title image.

To encipher a message each letter of the alphabet is encoded by indicting the type box that it is in and a way of indicating its position.

E.g. the letter ‘f’ = number 3 boxed in left, right and below or two dots boxed in left, right and below or single dot to the right of a box with borders left, right and below

Easy! Can you decipher the message intercepted by Agent Kat above?

If you want, you can make it harder to solve by combining it using something like the Caesar cipher.
