This uses a Vigenere cipher. The numbers can be decoded to a key, and the letters are the encoded message.

During the hunt, I’d say 99% of the people just put the letters into a decoder site (Boxentriq, e.g.) and brute forced decoded it, without ever actually figuring out the numbers portion.

The numbers can be deciphered into the Vigenere key by doing the following:

  1. Space the numbers out correctly to produce an A1Z26 encoded string of characters.
1 11 12 26 2 16 22 17 15 6 5 17 24 17 16 11 6
  1. Using A1Z26, this string translates to
AKLZBPVQOFEQXQPKF
  1. Using a Caesar Cipher shift to shift each letter up by 3 characters, this shifts it to
DNOCESYTRIHTATSNI

*Note: John confirmed this is just a coincidence. One unconfirmed theory suggests the reason for shifting by 3 is because it is the only number not included in all the numbers from 1 - 7. I’ve also heard this exact pattern (A1Z26 → Caesar shift by 3 → reverse text) was used in a past QR hunt.

1. Reverse that, and you get:

```
INSTATHIRTYSECOND
(INSTA THIRTY-SECOND)
```
