An entry in Fortnightly Topic Challenge #50: Escape Rooms

Without revealing too much, knowledge of geek culture and/or superb Google skills are required for this puzzle.


Coming from an anime convention and looking for something else to do, you and your friends find yourselves in the Puzzling Free-to-Play Escape Room. After scouring the geek-culture-themed room for clues and completing some physical puzzles that can't be replicated on PSE, you are left with five numbered clues in front of you. The door to freedom is locked with a five-letter combination lock; attached to it is a card that says "𝜈, 1, 5, 3, 4". Your phones (ie. Internet resources) are allowed for information gathering and cipher solving, but brute-forcing a cipher is forbidden. What five-letter code will lead you to freedom? Collaboration and partial answers are encouraged, but the one who gets the final code with a reasonable amount of explanation will get the green check.

Hints

  1. After a while with not a lot of progress, a voice comes from a speaker in the corner of the room asking, "Do you want a hint?" You accept, and the voice continues:

"Not to worry you, but the note attached to the lock could be a trap."

  1. (Bigger hint) Seeing you still working on the first puzzle, the voice goes on:

"It's time to d-d-d-d-decipher!"

  1. "If you're stuck on the first puzzle, you can try...

...working on the fourth one; the rebus can be solved independently of the other puzzles."

The Clues

Shingoki Rules

Adapted from A Shingoki Puzzle. However, it looks like these rules can't be directly applied to this specific Shingoki....

  • Draw lines between the dots to form a single loop without crossings or branches.
  • The loop should pass through every circled number in the grid.
  • For white circles, the loop must pass through in a straight line.
  • For black circles, the loop must make a 90-degree turn when passing through them.
  • The numbers in the circles show the sum of lengths of the 2 straight lines going out of that circle.

    $\begingroup$ Just double-checking: if I assume that the shingoki is normal except that we don't have numbers (it might turn out that e.g. the letters somehow determine numbers, but for the moment I'm not assuming that) I quickly get a contradiction in the lower right corner. Obviously you're not telling us explicitly what the rules are, nor even whether we should be trying to solve this thing at all, so this could be perfectly correct, but I'd just like to make sure it isn't an oversight. $\endgroup$ – Gareth McCaughan Mar 2 at 20:12

    $\begingroup$ @GarethMcCaughan The rules provided are for a standard Shingoki (to keep the puzzle self-contained), but the Shingoki provided is not standard; part of the puzzle is figuring out what to do with it. I've gone over it myself countless times (including once more just now) and I am reasonably certain that there are no oversights in the Shingoki. Hope that helps! $\endgroup$ – samm82 Mar 2 at 20:33

    $\begingroup$ Can we take hints, like a real escape room? :) $\endgroup$ – Anonymus 25 Mar 6 at 0:34

Partial answer

Since this has been around for so long, I figured I'd share my progress so far.

[NB: I did need to bruteforce the first cipher, and I would've never gotten it without doing that. I also bruteforced the other one, but don't plan to use the information until I figure out how I was supposed to have gotten the key.]

1.

This appears to be a riddle with answer YUGI MUTO, a character from the anime Yu-Gi-Oh. I am only vaguely familiar with the show, and know there is some Egyptian theming involved in it; I'm not sure what the other references in the poem are.

Decoding this as Vigenere with key YUGIMUTO gives five cryptic clues:

Break out mineral and gem (10)
TOURMALINE*
Fish eggs lining head of lettuce (7)
RO(MAIN)E
Reptile somehow got air after all (9)
ALL + IGATOR*
Sick after taste of disgusting herb (4)
D_ + ILL
East Nevada club leads to jealousy (4)
E+NV+Y

The first letters of these clues' answers spell TRADE; I'm not sure how relevant that is.

The images here appear to be:
- FIAT?
- ??? - a hamster ball

- PERMU (symbol for male in flag of Peru)
- iii, ??? (this is the album Miiike Sn!!!w by the band Miike Snow)
- the nautical flag for D

I have no idea what the remaining images are cluing, or what we're supposed to do with these. The second row almost makes the word PERMUTED, but I don't see a reasonable way to get "TE" from the second image.

I'm not sure what was supposed to give this to us, but decrypting the text with keyword HIE gives the following (with spaces and punctuation added by me):

TAKE THE SHADES FROM CLUES UNIQUE
COUNTERCLOCKWISE FROM THE PEAK
THREE MORE HIDE WITHIN THE CLUES
THE FIRSTS OF ALL FOUR MUST BE USED
(P.S. WHITE SHOULD ONLY BE USED FIRST)


Some completely wild guesses for 3:

In the Shingoki, the black letters anagram to ANDROCLES / COLANDERS / AND CLOSER, and the white letters anagram to RONALDS/ARNOLDS. Neither of these seems to be productive.
The Shingoki grid has the right dimensions to be dissected into Braille letters, but they don't seem to all fit in the A-Z range.
The counts of the letters in the Shingoki grids aren't particularly enlightening:
counts of letters in both black and white

In the answers for 2, ROMAINE is a proper subset of TOURMALINE, both of which are isograms. If this is important, I can't figure out why.
The answers are strange enough that there's probably more to them than just their first letters. There are 34 letters in them, and 39 black circles and 27 white circles; these add up to 100... which would be nice if the grid was 10×10, but it's actually 12×12.

  • $\begingroup$ Your anagramming could also yield rot13(YBFR P NAQ E / NAQ Y BE F)' - would doing that make the grid puzzle solvable at all? $\endgroup$ – Stiv May 14 at 18:06
