News about Noita cryptograms
Last year I reported about nine encrypted messages from the computer game Noita. They are still unsolved, but there are new clues.
Over a year ago, blog reader Tobias pointed me to a crypto puzzle. “It involves nine (probably) encrypted messages in the computer game Noita,” he wrote. “These messages consist of eye symbols looking in five different directions.”
Noita (Finnish for “witch”) is an action-adventure computer game. The player plays a witch who, on her journey through an underground cave system, tries to get deeper and deeper and to the end. Whether the player walks the path, teleports, or digs through the earth is up to the player.
The nine eye messages
The nine messages mentioned by Tobias have been known for about two years. There have been intense discussions about them in the Noita community, but they haven’t yielded much so far. On a fan page they are shown on two graphs. Here are the first four cryptograms, which are called West Side Messages:
There are also five East Side messages:
The alphabet used consists of five symbols. Each symbol can be seen as an eye. The differences arise from the pupil being at the top, bottom, right, left or center.
On the said fan page, a document is linked in which numerous Noita players have written down their thoughts and findings about the eye messages. A transcription of the nine cryptograms can also be found there. It makes sense that the five eye symbols are represented with the numbers 0 to 4. The order is different from the two pictures. In order not to make things too confusing, I have taken the order from the discussion document in the following, even if it does not agree with the pictures above:
Message 0 (East 1)
Message 1 (West 1)
Message 2 (East 2)
Message 3 (West 2)
Message 4 (East 3)
Message 5 (West 3)
Message 6 (East 4)
Message 7 (West 4)
Message 8 (East 5)
One possible interpretation is that each pair of numbers stands for one letter. Since there are 25 different number pairs (00 to 44), one could represent almost the entire alphabet in this way. This would correspond to a Polybius or ADFGX chffre. However, there is not an even number of digits in each line, which makes the assignment difficult.
An interpretation as ternary numbers is also possible and is described in the linked document. In addition, there are frequency analyses and a bit more information there.
After my first blog post on the Noita cryptograms in August 2021, there were some interesting comments, among others from The_Piper. Despite all this, the mystery remains unsolved to this day.
A few days ago I received another email from Tobias. Apparently there are some new findings about the Noita cryptogram, which I am of course happy to pass on to my readers:
- The nine messages are between 99 and 137 characters long. In total there are 1036 characters.
- No number appears twice in a row.
- The same number can appear at adjacent positions in different messages.
- The eyes can be read in a certain geometric order, so that they form messages of the numbers 0-82 in groups of three in the Base-5 number system.
- The numbers are statistically uniformly distributed.
- The messages contain long isomorphisms.
- The messages all start with different numbers, but are followed by a longer sequence that is the same in several (sometimes all) messages.
- There are a few cases where such identical sequences occur further back in the messages.
Tobias also sent me three more links:
- Document with the messages
- Overview of the cryptanalysis of the messages
- Summary of the findings about the messages
Can a reader find out more about the Noita cryptograms with these pointers?
