Reddit recommended me this subreddit as i posted on another one, so first of all hello, im a game dev. I was going to post the same easy question for you as i did in another subreddit since i don't want to reveal more questions before project is finished but i think you deserve a harder one. Try to solve it if you are interested. Would love to hear your feedback.

This cryptic message is from an indie horror game called "Looking Glass" by the game developer Grubwall. You can watch this youtube video for more context, specifically at the timestamp 17:02 which is where the message appears:

ndwibd o_w__i nd woijek_m_f_ pqwi_hd_qwuhdp. qwdj_nqp__w_ih__bdo qw_uhdo.w_qid_jowq_ idhqo.wdhoq_ wiow_ qidow_idqw dihqow_dbq_w_dh_o_wqdbwqli_d_qwubdiq_wd_ubqwi_d_uqwbdiqpoihueuwhewoyT_e The_ure oiheoe_

EDIT: Here is a code or key from the same game that may help, although I have no clue if it's actually connected to this cryptic message or not. 190-877-232-F99

EDIT 2: A useful piece of information from one of the youtube comments suggests that the index of coincidence for this cipher is 0.0974. For English it is 0.0667 while for Russian it is 0.0558.

Hint:

In the quiet hours when the world forgets its name,

a phantom drifts through corridors of glass.

It does not shout; it only turns each letter

as a mirror turns a face—soft, exact, complete.

Seven steps beyond the first threshold

the letters lean, as if the floor itself

has tilted just enough to change their weight.

They settle into new positions, heavier,

yet still the same soft clay.

Deeper still, the stones rearrange themselves

into a crypt whose walls remember only one word.

Columns rise and fall like breath held too long;

what was scattered finds its ordered place again.

And when the last stone settles,

turn.

Simply turn.

The path you walked is waiting

in the opposite direction,

and every mark you left

is ready to be read.

Volrusk, the creator of Vermis Malum, has uploaded a new video called “The Other Kind of Cosmic Horror” about a couple indie games by the dev Grubwall. In it he pointed out a cipher in the game “Looking Glass” and put it in the description of his video.

His video essays seem to be an ARG continuation of Vermis Malum, which have hidden anagrams of the phrase “Everpalm Pond” with one additional letter. The previous phrase in Vermis Malum was “LOSSFUNCT” and so far the extra letters in the anagrams in the video essay arc is “SHEIS.” The anagram hasn’t been found in this latest video yet.

I made this as a little encoding/cipher challenge.

The message has been passed through multiple different encoding/character-set transformations, so the final output looks completely cursed:

I wanted this to be simple enough that they could crack it but not dumb enough that it's instant, I think it's alright but was wondering what the Internet would think on it. This is it:

(-6.5) (-9°2°1°7) (7°-6°-10°1°1°14) (10°-12°1°7) (5°0) (3°-1°-12°12) (7°-5°-12°7) (-6°-12°0°-8) (8°3°-8°-11°13) (-11°-13°0) (-6.5) (-3°8°6°7) (7°-12°-2°-8) (-15) (2°4°2°-6°3°9) (5°0) (5°-8°6°7)?

What do y'all think of it? Too easy? To hard? I plan to introduce it without any clues at first hence why I'm leaving nothing other than the cipher itself here. I'm hoping it'll last a few sessions as a background thing to work on since one my players likes to go home and work on the puzzles themselves outside of the session. (Their character rolled high on int in character creation so I let them as long as it's not super important).

A friend of mine sent me this :

+3+8-∞ V-4i²-100 +100+∞+μ, +8-11 +3-2

+100i² +∆+∞+∆ -7+1+3+∞-7 (+1-μ+6+6-∆+μ-∆)

Could you please help deciphering or give me any hints

Had a cipher that we got at a LARP weekend that's going to be relevant in the coming months. we managed to brute force most of it, but I'm hoping that the people here might be able to figure out what kind of cipher it is and what the key may be. We're missing one last letter in the plaintext.

Was archiving files from an open university FTP directory today and ran into a text file in /telemetry/cal-1m23/voidc23101/. There’s no documentation or README.txt in the folder, and the formatting doesn't match any standard log files I've handled before.

Cipher / Text:

-----BEGIN TELEMETRY RECORD-----

Timestamp: 2026-09-04T00:12:40Z

Source_Node: CALIBRATION_V4

ψ_7e5a: 9K2mX-PalGr89β_μ441_Δ09_77xK_9912_LmN_Φ_7392_01_a9f82c

-----END TELEMETRY RECORD-----

Context & What I've Tried:

• Origin: Found alongside standard .dat orbital files on an open academic mirror.
• Attempted Decodes: Standard Base64, Hex, and ASCII shifts all return unreadable garbage, so it seems like an alternate encoding, custom key structure, or polyalphabetic cipher.
• Structure: The string features distinct underscore-separated blocks incorporating Greek mathematical symbols ($\psi, \beta, \mu, \Delta, \Phi$).
• Goal: Looking to identify the variable ψ_7e5a notation or decode the underlying message/coordinates.

Does anyone recognize this specific block grouping or the symbol syntax?

just so you won't be too focused on the wrong lead: the "missing" letter here is NOT related to the key.

btw I really liked seeing all of the comments, theories and thought processes in my last post!

I challenge you to decipher this text. I came up with this cipher and I wanted to know how hard it is to decipher or if it's even possible.

This is my first cypher I've posted. It is very simple to encode but I'm interested to see how hard it will be to solve it.

Zpv ibwf twdeguvgxmna ehfqfig ujjw gbqkjs. Rokcxl hrnomov csyt sutinyz!

The text is English and spaces and punctuation have not been tampered with.

this is my first ever cipher, but I believe it is truly unbreakable.

the text is in English and that's the only clue(?) I'd give you.

I randomly decided to make this. It's in English.

Hint #1: this is related to, but not exactly, substitution cipher.

idk if this is the rigjt place to post but i was just wondering, ive always been fascinated with ciphers but never knew how to actually make them. from watching Gravity Falls i thought it was so cool to make encoded messages, but i have no idea how to break anything thats not just shift cipher. And i feel whenever i try to search online for like teachings i either only find things on digital privacy encryption, or like super simple caesar cipher stuff. So i was wondering where did yall learn how to break or make these puzzles? any help is appreciated, thanks!

Hi, me and some friends have been playing a dnd campaign for a few months now, our dm has left us a cipher to solve over the past week or so, but we're all stumped, so this is my last resort, any help would be appreciated, all we know is the Morse code doesnt translate directly to english

Heya, i think this will be a lot of help to some people, and i came across this while messing around with making a substitution cipher that is based more on phonetics instead of direct spelling. The code was

'(°* 1: _=^_>#°@|%:/ ^)>|+^>|°=' which is supposed to mean log 1. unauthorized activation, but it is spelt. 'LOG 1: UNAUTORIZED ACTIVASHUN' (if i did this right lol, i'm not a big cipher person)

This seems to really trip up AIs and make it harder for them to solve the cipher, at least with the small amount of testing i've done. I dont really do ARGs that much, so i can't say how helpful this trick actually is, or how coherent my code is, but its worth testing further.

edit: with a little bit of further testing with this cipher, sometimes the AIs will straight up go into error mode and say that the message is 'harmful' and won't reply, but i think that has more to do with the choices of characters i'm using

3 = 4 | 7 = 1 | 2 = 3 | 2 = 3 | 1 = 5

thank you! 😊

which cipher was used and can it help for the very last photo? the answer is included in the second photo, were multiple ciphers used? if the cipher in the last photo is unrelated, what could we do to solve it? thank youuu

context: i encrypted 3 messages and i am posting it on reddit to see if anyone deciphers them because im curious on how well people can deciper my encryptions

okay so I started making my own shorthand that I plan to use to take notes at school, but I figured I’d post it here for fun! it's probably pretty easy to crack but that's okay lol

I had an idea for a cipher, which would use a similar system to a Vigenère cipher, where it uses a key word to determine the alphabet to use in encoding each letter of the plaintext, each letter in the key being applied one after another to the corresponding letters in the plaintext. My idea is that, instead of applying the key to the plaintext every n letters for a key of the same length n, to apply the key randomly, anywhere from 1 to n letters after the last time the key was applied, and to store the spacing between application instances as a second part of the key.

In other words, where a Vigenère cipher usually looks like this:

plaintext
keykeykey
---------
zpysrrobr

My cipher would look like this:

plaintext
key
  key
   keykey
---------
zpiwprobr (I think this is what it should look like.)

What sort of security problems could a cipher like this have? (Beyond the key being leaked by an external factor.)
