Answer: Secret Code #230

The secret message says:

MUG

The secret note decoded: MUG
The note, decoded.

Letter by letter

Secret letterFNT
Real letterUMG

Decode it with Python

This program does the decoding for you. Change the secret and the code to crack other messages!

secret = "NFT"
message = ""

for letter in secret:
    if letter.isalpha():
        position = ord(letter) - ord("A")
        message = message + chr(ord("Z") - position)
    else:
        message = message + letter

print(message)

When you run it, it prints:

MUG

Did you know? The mirror code is thousands of years old. It was first used with the Hebrew alphabet, where the first letter swaps with the last, the second with the second-to-last, and so on.
