The first end credits cryptogram.
The following is a list of cryptograms from Gravity Falls. There is a cryptogram during the credits of each episode. They use Caesar ciphers, Atbash ciphers, the A1Z26 cipher, and keyed Vigenère ciphers. Episodes 1-6 use the Caesar cipher, episodes 7-13 use the Atbash cipher, episodes 14-19 use the A1Z26 cipher, episode 20 uses a combined cipher (a combination of the A1Z26, Atbash, and Caesar ciphers), episodes 21-40/41 use the keyed Vigenère cipher. There is also a complicated combined cipher hidden throughout the "Dipper's Guide to the Unexplained" shorts.
