On the Subject of the Triangle CM

A machine that knows no bounds when it comes to ciphers.

From the Shape Cipher module by TracksJosh.

Create a key using the keyword on screen 1 and the Boolean Expression on screen A. Replace the * with an # in the Triangle Key below using the number on screen B with the 1st digit as the row and the 2nd digit as the column. Replace the rest of the *s with the key you made in reading order. This will be referred to as the Triangle Key.

Concatenate the indicated directions on screens 2 and 3 in that order. If the Submit Button is white, reverse all the indicated directions (CW <-> CCW).

For each letter of the encrypted word, do the following:

  • Find the Nth letter of the encrypted word in the Triangle Key.
  • Move 120° in the Nth indicated direction.
  • If the letter you end up on is a #, keep rotating in that direction til you hit a letter.
  • The letter you end up on becomes your Nth decrypted word.
