List of cryptograms

The following is a list of cryptograms from the Gravity Falls episodes. There is a cryptogram during the credits of each episode. They use a Caesar cipher, Atbash ciphers, and Gematria ciphers. Episodes 1-6 are Caesar ciphers. Episodes 7-13 are Atbash ciphers. Episodes 14 and up are Gematria ciphers.

Caesar ciphers
Caeser ciphers substitute the original letter for the third letter before it. In the case for letters A-C you must cycle through the end of the alphabet.
