On the Subject of the Collon CM

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

Create a key using the keyword on screen 1 and the Boolean Expression on screen A. Make sure to replace any Js with Is. Rearrange the key into a 5×5 matrix.

Do the following for each letter:

  • Find the Nth letter of the encrypted word in the matrix and use that as the row.
  • Find the Nth letter on screen 2 in the matrix and use that as the column.
  • The intersection of the 2 letters will give you the Nth decrypted letter.

Finally, if any of the letters on screen 3 match at the same position as any of the letters of your encrypted word, replace that letter with a J. You should now have an decrypted word.

Example

Encrypted Word: VIRVIGP
Screen 2: IDMWFLE
Key: ABCDFHKLMQRSTUVWXYZPIGEON
Screen 3: RVEEYOO

VI → R
ID → O
RM → U
VW → R
IF → N
GL → E
PE → Y
ROURNEY + RVEEYOO → JOURNEY
Decrypted Word: JOURNEY
