Why shouldn't the rule be "each row has one X in the same place in each grid and everything else is random"? and so the answer is now H. Fundamentally, this is the issue with these puzzles, you have to arrive at the same conclusion as the setter to be "right", even if yours is also a logical tautology. Anyway, now for a puzzle, seeing as we all love series based ones... 3, 1, 4, 1, 5, ...?

I could continue it and it would make less and less sense. Let me show you the longer sequence OEIS A027887. According to WolframAlpha: 18, 20, 22, 23, 24, 27, 30, 33, 35, 36, 40, 44, 45, 46, 48, 50, 54, 55, 59, 60, 63, 66, 70, 72, 77, 80, 81, 84, 88, 90, 96, 99, 100, 108, 110, 117, 120, 121, 126, 130, 132, 135, 140, 143, 144, 150, 153, 154, 156, 160, 162, 165, 168, 170, 176, 180, 187, 192, 198, 204, 216, 240, 264, ... Only read if you want to be angry about bullshit: It's the bidding sequence in the card game Skat. You would know it when you play, because each round starts with verbally following that sequence. It's a sequence based on n*(9, 10, 11, 12) (n>=2) with random numbers for special rules like 25 shoved in there. Good luck figuring that one out without the relevant context. To be fair, that knowledge is quite common in Germany. cant cook creole bream has a new favorite as of 07:32 on Sep 22, 2022 |

That leaves a considerable gap and doesn't map to the real numbers. If the "digits" are real numbers between zero (inclusive) and pi (exclusive) then the value would be (10) base pi. At which point is necessary to ask if 0.qqqqqqq=pi, where q is pi minus epsilon.

Got halfways but now it's time for a shower and to get to work Adams is now reading Davis which was brought by Brown, who must himself have brought Clark as none brought themselves. Using first letters: A: D B: C C: A/B D: A/B Poet is reading a play, and the novelist has never read history which means they haven't switched and neither of them can be A or B: Hist: A/B Poet: C/D Nov: C/D Play: A/B Thus Hist/Play = C/D (or vice versa) Poet/Nov = A/B (ditto) But there I am stuck. There's one piece of info that I'm missing, which would probably solve the whole thing in one go lol

Search for https://en.m.wikipedia.org/wiki/Zebra_Puzzle where the usual approach is to set up the grid of all possibilities then start removing logical contradictions. Image search will give some examples. The problem as stated has a lot of misdirection. It doesn't really matter who brought what, for example (and in this case there's no guarantee of the books being by four different authors). Pheun posting so setting up a grid with proportional fonts is ultimately impossible.

Carthag Tuek posted:Got halfways but now it's time for a shower and to get to work I say you have an incorrect conclusion here. Poet reads play, novelist is not reading history nor novel hence read poems. Historian thus reads a novel, and the playwright reads history. These flips would have meant someone was reading their own book initially: Hist/novel, Hist/play, poet/novel, poet/play. That leaves Hist/poet or Novel/play as the flip, but if the novelist had flipped with the playwright then the novelist was reading history. Contradiction, ergo A/B are the historian and poet (in some order). Moreover it can be shown that if person c is reading author B, then person a is reading C, which contradicts the book that b exchanged with a. But as to distinguishing between these two options, it looks under determined: If ah, then ahND, bpWC, cwHA, dnPB. If ap, then apWD, bhNC, cnPA, dwHB. Lowercase is who/what they are, uppercase is what/who they read. W=playWright, P=Poem.

Yeah I did a couple on paper but they're a pain to type even on a computer lol. I figured out who reads who of the professions pre:Each have 3 options, and we know the Poet is reading a Play, so we cross those both horizontally and vertically.
We also know the Novelist is not reading History, so cross that:
Hist Poet Play Nov
Hist · x
Poet x · √ x
Play ·
Nov x x ·
This leaves only Poems for the the Novelist to read, and thus the Historian must read a Novel,
leaving only History for the Playwright:
Hist Poet Play Nov
Hist · x x √ Historian reads Novel
Poet x · √ x Poet reads Play
Play √ x · x Playwright reads Historian
Nov x √ x · Novelist reads Poet

Re: the Galaxy Brain logic problem and pattern problems above: I've thankfully rarely encountered those types of problems when it comes to applying to work, but they just strike me as so unfun to do even with no time limit working against you. They seem very loose for lack of a better word, and you can't be sure if you've got it 100% right in some cases. Not to mention the times when the author makes a mistake/bad assumption, rendering the puzzle unsolvable... Puzzle's don't have to always be easy, but some trust is needed between solver and setter. I think this piece by an indie crossword writer puts it into words nicely. While it is just about crosswords, the best puzzle writers I know of make it a point to have one solution to their puzzles that can be reached through logic or knowledge. I'm sure something similar could be said about puzzle game design as well. On a side note, anyone do the Wall Street Journal crossword? they're usually interesting from what I understand, and they even have a contest every Friday where the winner gets a mug. And hey, there's a new puzzlehunt in town! It's being put on online in a couple of weeks and will have 20-30 puzzles, along with presumably a couple of metas. You can have a look at the site and decide if you're interested, and maybe if there's enough buzz teams could be made.

in the 90s they sometimes to had them in the uh "vacation activity books for bored kids" and they were my absolute favorite. crosswords are simple, rebuses (rebi?) are alright, but logic puzzles are my jam (as long as they dont require any external info to solve). also i dont think ive actually tried one of these since back then

Carthag Tuek posted:if that is the case i want the author hanged Clark is a novelist reading poems by Adams. Davis is a playwright reading an history by Brown. Adams is a poet reading a play by Davis. Brown is an historian reading... a play by Davis. I claim this satisfies the listed constraints because each is reading a book by one of the others, and it makes use of the point that the novelist has only written one book and is unlikely to be known or included in the reading list.  It seems likely the author screwed up. If this is pre-computer, that seems likely.

PhantomOfTheCopier posted:I have found at least eight solutions but the most compelling is perhaps: FWIW the solution in the book is "Adams, the poet, was reading a play; Brown, the historian, was reading a novel; Clark, the novelist, was reading poetry; and Davis, the playwright, was reading history." Usually there are enough clues to nail down one fact that has to be true and work from there, but in this I got as far as Adams is reading Davis' book and blanked. The book doesn't explain any of the solutions. It also was written in 1957 so there probably wasn't much oversight (e.g. I'm 99% certain one of the earlier given puzzle solutions would only work if the problem said someone was older when the text said they were younger). A lot of the clues come in the form of 1950s era societal norms, like former roommates mean they were the same gender, all women take their husband's last names, married couple means opposite gender, etc. You know what, gently caress this book!

minato posted:I highly recommend the youtube channel Cracking the Cryptic. It's two middle-class English guys (and puzzle champs) doing mostly Sudoku-based variants, and they always have a link to an online version of the puzzle so you can play along. I like to try the puzzle myself, and then if I get stuck I can play the video to get me past the hurdle. Jumping on a post from page 1 to say thanks. I clicked this thread and watched this video out of mild curiosity despite never having even looked twice at a Sudoku puzzle before, and now I'm actually really interested in learning more. There seems to be a lot more to it than I had considered - especially with the amount of variants and specific rulesets that show up. I've been playing a random app that I found, and despite being a beginner a lot of the Easy-Medium difficulty puzzles from it are actually quite simple to do given enough time, but I suspect I'll soon hit a wall where they'll require much more complex logic to resolve. I already saw one CTC video that had Simon explaining how the corners have to have the same digits as some other region of the grid based on Set Theory which is a lot more involved than I ever thought Sudoku could be.

Yeah, variant sudoku is where it's at. I used to buy booklets of puzzles from the convenience store, but they're so rote and boring compared with variant sudoku. I was mulling over posting this Cracking the Cryptic video, which is insane because it's basically pointer operations (to anyone familiar with low level computer programming), and I'm surprised it has a solution at all. It's one of the rare videos where Simon opens it on camera for the first time live, and his reaction is hilarious. https://www.youtube.com/watch?v=5CafO_kB4ko Although I'm still terrible at variant sudoku, I've really learned a lot by watching these guys. Unlike me who just throws spaghetti at the wall most of the time, they're very methodical; they have a good intuition of where to focus, and what techniques to try. And they're tenacious - most of the time I'd just give up or need a break, but they always push through.
