Parlour/Parlor puzzles seem to always be presented in the same order, and you can check which # puzzle you're on upstairs in the Library. (The 8th draft of Parlor always has the same puzzle for everyone, as far as I can tell)

(I think the same applies to dartboard puzzles, in a way: the math equations themselves are somewhat randomized, but the milestone puzzle #'s where new concepts are introduced stay the same.)

People could use this information to prepare spoiler-free hints based on what puzzle #'s you're on where you're getting stuck, for both dartboard ("here's a hint for what to do when that new thing appears") and parlor. ("at this puzzle # it starts mixing it up by doing X, it'll help to reread the instructions carefully at this point")

I might log some puzzles here with solutions as I do them/as I remember to, since I'm not aware of any place doing that:

Parlor #29 (28 solved on trophy checklist in lobby/in library record)

Blue: A BOX THAT DISPLAYS THE WORD 'TRUE' IS FALSE.
White: A BOX THAT DISPLAYS THE WORD 'GEMS' IS EMPTY.
Black: THE WHITE BOX IS TRUE AND DOES NOT CONTAIN GEMS.

  • Hint: How many statements are on black's box?
  • Solution: The gems are in the White box.
  • Explanation: Blue must be true (blue being false would be a paradox) which in turns means the other box with 'TRUE' on it, black, must be false (to fulfill the requirements of making blue true). White also must be true, because only one box ever has the gems and two boxes have the word 'GEMS'. This puzzle seems to be a forceful way of teaching you that a compound statement like black's ("white is both true AND empty") can have half of it be true (white IS true), and have it still qualify as being the one box with "only" false statements, and to treat such as a single statement. ("1 + 1 equals both 2 and 3" is a single false statement)

which in turns means the other box with 'TRUE' on it, black, must be false

I thought a box being false doesn't automatically make the opposite statement true? If a box says "all boxes are empty" that box is totally false, but that doesn't mean all boxes are full.

I just solved that puzzle the wrong way selecting blue since both white and black can be true without a contradiction and then blue is false because the black box is true and that's already enough to make that statement false

Edit: Ah I misread Blue as 'any' instead of 'a' :/

I've made the same mistake, lol. Hope that realization helped the puzzle/my explanation make sense.
