@Rubio You should format your messages properly (i. e caps and punctuations), otherwise they take bit of extra effort to read.

Q: I hope your internet's working

Challenger5I'm new to this StackExchange - I'm more active on programming stack exchanges. So here's a computer-themed puzzle: 4K5L3RdR-PASTE That's it. I'll leave you with one clue - The title.

 
@ArbitraryKangaroo You should not delete your comments, otherwise conversations take a lot of extra effort to understand.
And sorry, I don't always capitalize - bad habit. I'll try to do better, good sir.
 
 
3 hours later…
8:29 AM
What's a better title? "A weird, spooky ..." or "A spooky, weird ...". I obviously can't say what the "..." stands for, except that it's halloween themed.
I'd say option 1, but I'm not sure.
 
8:47 AM
"I saw weird stuff in that place last night; weird, strange, sick, twisted, eerie, Godless, evil stuff"
"...and I want in!" - Homer J. Simpson (Homer The Great [The Stonecutters episode])
"Weird, spooky ..." possibly no "A"?
 
I think both may be opinion
"that house is spooky" is opinion, not material, right?
 
:) yeah I was kidding.
 
@JonathanAllan The problem is "..." could for example be "bottle". So I think the "A" must stay :P
 
oh (passes hand over head)
yes it may need to, I wasn't saying no "A" for sure
 
8:53 AM
I think I'm going to stay with "A weird, spooky" because it will nicely fit :P
 
I'd go with "weird and spooky", as in "well that sure is a weird and spooky puzzle title"
 
@Alconja True, that sounds better.

Q: Treasure hunt of the century

stack readerWill you help my find the treasure? I just can't find it! The only hint I have is Paste->e28DSjPF

 
@JonathanAllan I guess you can put me in the "not goa/psy lover" category... this is the most recent album I bought :)
 
video not available :(
Music good, singing not so sure...
Maybe you'd prefer something like this (a cover of a 1982 Heaven 17 song) youtube.com/watch?v=MfMa2lrFxhY
 
:) an acquired taste to be sure... a mellower track
Lol. I'll pass.
 
9:41 AM
That singer... maybe it's my Britishness, but his accent just grates on my ears :(
music is indeed nice
 
Singers are like that. I hear loads of music that I really like except for the singer ruining it
 
...and mellow / hard is not something that has any effect, I listen to stuff ranging from Solar Fields to Drumcorps
(hmm, or is this harder, whatever)
 
@ArbitraryKangaroo I got a "someone mentioned you" notification here and it pointed me at ... "(removed)". Perhaps that was some kind of response to what I said about Winkler's book. Anyway, that's the last time I take any trouble to help you with anything. You are seriously losing goodwill here.
 
10:00 AM
@GarethMcCaughan Apparently he removed the comment I snarkily responded to earlier, too. Which was telling me "You should format your messages properly (i. e caps and punctuations), otherwise they take bit of extra effort to read." Because I guess it's hard to understand what I type unless it's properly written.
 
:) can't listen right now, but will come back to it. That being said, dillenger isn't necessarily a fair representation of my tastes either. I do listen to some mathcore and technical death metal stuff, but mostly more progressive metal/rock and post rock (and punk). This was my second most recent purchase.
@JonathanAllan the above was in reply to this... if it wasn't obvious.
 
Didn't he get some sort of official warning from one of the mods about his message-removing habits?
 
10:29 AM
Hey all
 
We need a new fortnightly topic challenge post, but I'm super-busy today and don't really have time to do it ... @LukasRotter you wanna do the honours again?
Actually, looks like it's our fortnight for unconventional tag fusion, so we'll need more than just copy-pasting last fortnight's post and changing the dates and tag name. @Alconja Maybe you'd like to do it? Was there ever a conclusion in that chatroom about how exactly to define the challenge?
 
10:49 AM
@Randal'Thor yeah I can do it. There was some wordage in chat that I think people were happy enough with.
 
Hi all
 
What do you people think about the recent pastebin mazes? Are they allowed?
 
would be better if they were i.stack.imgur. The one I solved was not amazingly imaginative though.
 
Not a huge fan of the use of pastebin (except for non-essential, convenience stuff), since it's likely to eventually become a dead link
 
10:55 AM
Agreed. Imgur is much more reliable.
 
I agree as well, I thought it was imgur at first, then the answers showed it was pastebin instead.
 
11:11 AM
@JonathanAllan I solved a puzzle thanks to your answer ^^
 
Always glad to be of service :) which puzzle?

Q: Treasure hunt of the century

stack readerWill you help my find the treasure? I just can't find it! The only hint I have is Paste->e28DSjPF Note

 
ahhh another paste
 
yes xD
I thought it was a bad puzzle when i read it because the previous one was about pasting too... but the idea of using different bin pages for text was kind of great hehe
 
oh, I like the double letter kk ee yy
 
11:15 AM
i didnt notice the "k" as I usually write "okk" lol
 
did the tool just tell you it was Rijndael-128?
 
and "ey" has meaning so i was stuck
 
@lois6b ^^
 
one of the text say: ask about it to the master locksmith Rijndael the 128th who lives in the city of Ecb.
 
Oh yeah :p
 
11:29 AM
@Randal'Thor Done. If any mods (@GentlePurpleRain?) are online, can you switch the featured tag over to the new one?
 
Sid
What is considered to be unconventional?
 
@Alconja "Ideally, puzzles should involve the two tags being genuinely merged into a single challenge, rather than just having a two step process of, applying tag A then tag B." Would a cipher that is presented in geometric form but could as well just be written as plaintext be valid?
 
@LukasRotter I think so. You've merged the geometry into the cipher in that way. You're not solving a geometry puzzle to get a cipher out.
@Sid That's up to the puzzle poser. But I think most people's gut feel will be fairly consistent.
 
Posting my puzzle now, I hope checking it twice is enough to avoid mistakes :P
 
Sid
Would this be considered unconventional tag fusion? Since it combines both riddle and steganography.. puzzling.stackexchange.com/questions/42403/…
 
11:40 AM
@LukasRotter Awesome. :)
 
@LukasRotter nice puzzle

Q: A weird and spooky clock

Lukas RotterOut of nowhere, a clock appeared on my desktop: (you don't have to be able to view the GIF in order to solve it, I think the "preview" image gives you all the minor clues hidden in it. I also included a text version) I also found a manual for it: While all clock hands are exactly 1 long, ...

 
Thanks, I guess this time everyone should add puzzles to the fortnight post on their own? (since it's their opinion it's unconventional)
 
Yes. Please do.
 
By "but with the start/end positions excluded" do you mean the one that's 3:15:15?
@LukasRotter ^
Oh, LOL you just edited it in :)
 
@Alconja Oops, totally forgot to include the tags in the post as mentioned in the chat room. Should I include all tags or just the one's which I deem unconventional, i.e. cipher and geometry?
 
11:55 AM
@Sid Sorry missed your message... I wouldn't say it's particularly unconventional. It's not that uncommon for riddles to use acrostic style clues, which are effectively steganography.
@LukasRotter Just the unconventional pair
 
Sid
@LukasRotter Your puzzles reminds me more of trigonometry than geometry.. tan, angle,etc..
 
@Sid There isn't a tag for that, but I think geometry still applies, since it's also about geometric shapes.

Q: A numeric sequence that I can find no answer of

alex180; 167; 149; 130; 118; 103; Y; Y = what number. It should be easy, they told me to think like a child and then go to mathematics but it looks like I can not find the answer. Any ideas?

 
Sid
@Alconja If you have the time, could you write up a wrap-up post for this? puzzling.stackexchange.com/questions/28494/…
 
@Sid Sure. Can't guarantee when I'll get to it, but I'll see what I can do.... What sort of stuff are you interested in seeing included?
 
Sid
12:03 PM
I want to know what your thoughts/inspiration was for that magnificent puzzle...
 
hehe I just spent a while golfing a way to make the string " ||"+(n-2)spaces+"|" - by binary(2^n * 5 / 2 - 2) indexed into " |", only to find it's the same byte length (12) as the string concatenation itself.
(actually one shorter than just concatenation but same as a join)
 
12:35 PM
@JonathanAllan Yeah, sometimes the easiest or most efficient way to code something is a look-up table.
 
Yep, I did some funky lookup table build using lexicographical permutation indexing for a phone app to perform ICM calculations (recursive combinatorial application of Bayes' theorem) - it can calculate deals for up to 23 people in reasonable time (others do up to 9 and some are slow). The code is pretty hard to comprehend though! I should get around to putting it on the Play store...
- although not much call for deals with more than 9 people
 
user189275
@GarethMcCaughan Well, the reply was: " Thanks. The latter is probably a 3d generalisation of ***." Sorry, But I seriously didn't mean it as to harass anyone, but as later I found out the ***'s may not work (and it was not breaking any conversion too), so I deleted it. And I actually need your help twice or thrice more regarding that book.
 
user189275
But, haha, banning for deleting comments ? A nice joke :P
 
I don't know whether banning was what was being threatened. But sanctions for antisocial behaviour that you continue despite being repeatedly asked not to by others who find it annoying? Yeah, I'd be perfectly happy with that happening.
 
user189275
@Alconja Awesome fortnight idea.
 
12:45 PM
@JonathanAllan Impressive! How many test cases did you run your code on? I hope << 23!.
 
user189275
@GarethMcCaughan Anti-social (?!) behavior ? :O
 
Yes, anti-social behaviour.
It makes conversations hard to follow. (You have been told this repeatedly.)
It annoys people. (You have been told this repeatedly.)
 
@ArbitraryKangaroo It annoys people. (annoying = anti, people = social). So, maybe not banned, but certainly loses you a bunch of good will...
 
It's obviously not the biggest of big deals. No one dies as a result. But it's rude and annoying, and persisting in it when you've been told it's rude and annoying is itself rude and annoying (because it indicates that you don't care about annoying other people).
 
@GarethMcCaughan "No one dies as a result." > @Lukas Rotter that isn't a drinking game, that's a fast track to death by alcohol poisoning.
 
12:48 PM
@RosieF Hmm, I've used it many times, but not often with more than 9 people. I've checked it against ICMizer and cardrunnerEV for a number of scenarios, and against Pokerstars at all my final tables (they often have off by penny errors in their calculations, obviously using floating point, whereas mine is using integer fractions)
 
user189275
After being told by Alconja and Deosuvi before, and realizing it was actually nonsense, I stopped deleting comments part of conversation long time ago.
 
Oddly enough I had a deal where we did an "even chop" and the shorter of the three remaining players was awarded the extra cent by Pokerstars :p
 
@LukasRotter ah, yeah, good point. I did assume no one was actually so foolish as to play that game.
 
Sid
I have just completed my latest conspiracy theory!!!
 
@Sid Well, that's what you'd like us to believe...
 
12:57 PM
Btw, dolphins taking over the world is not a myth.
 
@ArbitraryKangaroo Ah, OK. I hadn't noticed. (There's probably some moral here about how reputations are more easily acquired than lost.) Well done, then.
 
@ArbitraryKangaroo Well, suspension might be too strong in that case, but suspension isn't the only measure that moderators can take if a user doesn't cooperate. :P
I just realized that rhymes.
@RosieF I see what you did there.

Q: A crossword so simple, it practically solves itself

AlconjaAn entry in the 19th fortnightly challenge... A Grid Some Clues There are three examples of this in the finished grid Two answers that touch a corner, in relation to 25A (D) Contained in the rotational symmetry of the grid The clue above corresponds to an answer in this direction Position...

 
How come the bot now posts stuff from the main site, but not from meta any more?
 
1:23 PM
possible duplicate of The Unfinished Puzzle Section ^^
(reference to PPCG close reasons)
mind bending @Alconja. Really! So much self-reference, it's gonna be tough.
6D might be DOWN.
 
Sid
Is this answer here for any other reason than the author needed it for another clue?- might be "NO" (21D)
 
@JonathanAllan I don't think it's as hard as it looks... When I gave it a trial run, I was able to do it with almost purely logical deduction and only 3 or 4 educated guesses towards the middle. And there's very much a tipping point where the whole thing will crumble
 
Sid
The thing that this crossword references constantly-LOGIC? (Might be 17A)
 
And to anyone who was in chat the other day when I was talking about crossword ideas, that ultimately morphed into this. Super minor hint: I'm terribly sorry, but I failed in my attempts to squeeze an answer of ENGLISH into the grid anywhere. :(
 
@Sid, quite probable; but possibly "YES" (to keep symmetry) 18D(?) with "Do you really need a clue for this answer?" as "NO" (because we already have all the letters from 22D and 23A)
oh, although 21 itself makes the board asymmetric!
 
Sid
1:35 PM
22D is most likely a number, possibly one or two. because of the 9th clue...
 
"Number of letters in this answer" = FOUR
 
Sid
Number of "V"s that appear in the grid=ZERO?(4A)
 
I don't think you can know that one until later
 
Sid
V is an uncommon letter. So, I assumed it might be 0
 
What if one of the answers is twelve? :P
Or Vivacious :P
 
1:48 PM
@dcfyj Or seven or eleven?
 
Those too
I'd say, in numbers, that v isn't all that uncommon :P
 
@Sid It's four or five
I just threw up something like 80% in an answer, but I got stuck :)
 
@Sconibulus Nice work
 
(yes, I was solving in Snipping Tool) :)
I initially had FUN for 14A, but that didn't end up fitting, not sure what it might be now
 
noon o'clock?
 
1:54 PM
ten + 2 o'clock = noon
 
I know why you chose noon, just saying noon o'clock sounds weird
 
it isn't noon o'clock, the o'clock is on the other side of the equation
I'm pretty sure
 
13d is first
 
The clue resolves to 12 o'clock, which is noon. (i.e. 10+2 isn't the clue)
 
ah, that makes more sense

Q: Fortnightly Topic Challenge #19: Unconventional Tag Fusion

AlconjaThis is the nineteenth instalment of the Fortnightly Topic Challenge described here, with topics suggested and voted on here. This fortnight's topic is "Unconventional Tag Fusion" (suggested by Alconja), and will span from the 31st of October to the 14th of November. During this period, we will c...

 
I love how 4A is a circular clue, at the moment, both four and five are valid answers haha
 
It was a fun one to make. 19A is my favourite clue.
 
3D factors? and 14A art?
 
it implies that there's exactly one V in the unsolved area too (outside of 4A)
13a? That's not a thing :) 13d?
oooh, yeah, that looks good
that means 5d has a v in it
 
@Sconibulus how so? There are currently four v's in the crossword
 
1:59 PM
Oops 19A
 
two sevens, and one over?
never shares with one of the sevens
 
there are v's in: 20D, 24D, 9D, and 17A
 
oh, I missed even
oops
 
like I said, the answer can be four (no new v's) or five, a v in the answer itself
 
that makes 4A five
 
2:00 PM
It's circular :P
 
because four and five are the factors of 20
 
@Sconibulus It could still be four
Why does it have to be five?
 
the clue for 3D is Two answers that touch a corner, in relation to 25A
answers that touch a corner is 27A, FOUR, and then 4A FIVE, which are factors of 25A TWENTY
 
Ah I see what you mean, I was taking that as a corner that was touching 25A
i.e. 13D
So the only left to solve is 5D then
I find it funny that Wu33o answers in his comment correspond to mine in here :P
 
I went with "Entire"
it's probably not right though
 
2:09 PM
I'm off to bed. But well done for (99%) solving it. 26D may help you with 5D, though it may just confuse you more.
If you're still having trouble, ask @JonathanAllan
 
If who is having trouble with what?
 
...man, someone really doesn't like me. Third puzzle in a row with a downvote within the first hour
@JonathanAllan :) 5D
 
salt vote
Oh I was doing something else almost crashed my computer :p
 
@Alconja I feel like that person is downvoting everything, same thing happened to my last puzzles. And also to my current one as soon as I saw your comment here, LOL :P
 
:) Maybe whoever it is only likes one very specific type of puzzle
 
2:12 PM
I downvote everything Alconja posts as a rage-protest of pure jealousy. :) Your puzzles never cease to amaze.
@Alconja That "I need you to listen" one Sid referenced earlier? Man.. That is sick beautiful.
 
:) thanks
 
Sid
@Alconja You in Japan/Hong Kong??
 
user189275
@Alconja: Your quickest puzzle is now solved :P. A new puzzle on my to-solve list.
 
@Sid Close. Aus.
Looks like @DanRussell got 5D
Which should clear up why 26D is TEN
 
Ah ERRORS :)
 
2:18 PM

44 mins ago, by Jonathan Allan
oh, although 21 itself makes the board asymmetric!
 
Btw, this has to be edited. Not sure how, I guess switch the [tag:] and links with "Unconventional tag fusion"?
 
huh... although I don't quite understand why that's 10
 
user189275
@Alconja: Is there something meta in the crossword remaining ?
 
No. All done. Just a quickie for the fortnightly challenge
@Sconibulus If you rotate the grid 180 degrees, the points at which the "errors" appear, align with the letters T, E, N.
 
ahh
 
2:22 PM
@LukasRotter how about that edit?
 
I'm fixing it
 
@JonathanAllan the tag link still has to be removed, but otherwise I guess it's OK to use kbds as formatting
 
user189275
@Alconja I suppose you shouldn't post quickie puzzles. This is somehow misfitting the question history. (Well, aren't you posting any rep up ? You should post at-least one)
 
@LukasRotter yeah just got rid of the link to the tag.
 
user189275
@JonathanAllan It's suggested by Emrakul ? (Not Alconja ?)
 
2:26 PM
Note to self, make sure you have not typed 566 when attempting to calculate StrictSenseBallotNumber(56)
I dunno
I just fixed the tag thingy
brb
 
I fixed the rest
 
With the kbd formatting we could even remove the ugly blank part and include it in the blockquote?
 
@LukasRotter Good call. Done.
Anyway, I'm off. Night all.
 
...I nearly had this one:

2:39 PM
Oh it wasn't already separated from the previous one? I didn't even notice.
gn Alconja
 
@ArbitraryKangaroo you said you weren't removing your comments any more, but I see it isn't true.
 
@GarethMcCaughan I think he only said he will not remove comments already part of a conversation, the removed comment was directed at me about my puzzle. (no prior conversation)
 
It's not clear to me that this makes anything any better...
 
In my opinion anything said in chat is part of a conversation...
 
@GarethMcCaughan I also don't think it's good, I am just saying that he technically wasn't saying he will not remove any comments any more. (at least that's the way I interpreted it)
 
3:06 PM
@dcfyj Unless you join the room, write "meow", remove it, and then leave the room... :D
 
And at which point people would talk about it, therefore, part of the conversation :P
 
@dcfyj No, it would be removed before the conversation starts. Therefore the subsequent conversation would be about the (removed) ... which is fine. :D
In any case it wouldn't disrupt previous conversation.
 
If you're joining a room that's implying there are people in it. Why pray tell, would you join an empty room to chat in?
 
@dcfyj I could join a room with people, write something random and leave, because I can. :D
 
@dcfyj To chat with anyone who might come along later?
@dcfyj I might join an empty room to read the past conversation.
 
3:10 PM
@RosieF Would you join an empty room to type "meow", delete it and leave? That is the question.
 
^
 
Sid
And Why exactly would someone do that??
@IAmInPLS Hello, long time no see...
 
@Sid Why not? :D
 
May I interject a brief question? You know the types of puzzles where Mr. Pink is Mr. Brown's neighbor, and Mr. White drives the Honda, and Mr. Green is an accountant, and the wife of the man who drives the Chevy is named Susan, and so on .... what tags are those puzzles supposed to be?
 
@Rubio [tag: logical-deduction] I think?
 
3:16 PM
@Rubio einstein puzzle, logical deduction I think. I don't think theres one for logic grid anymore
 
@Rubio There are already puzzles like that, search einstein puzzle? I think, something comes up.
 
Have an example
 
Nvm, the "einstein" tag was removed, not the logic-grid tag
 
@LukasRotter by the question I just linked, I'd said the still exits :P
 
Speaking about meow... Once I was in the street, and I hear a cat meowing from a balcony of a nearby house. And until here, nothing strange, except that the cat wasn't meowing, it was actually saying the word "miao" (meow in Italian). :|
 
3:18 PM
@dcfyj corrected myself before you could :)
 
Yeah, I didn't type fast enough :(
 
I'm asking because different puzzles of that type get a modestly wild assortment of tags. Looks like logical-deduction and logic-grid are the favorites though.
 
I take it you're making one?
or have made one
 
I'm nearly finished.
 
cool, I love that kind of puzzle ^^
 
3:19 PM
Does logic-grid and liars make for an unconventional tagging?
 
I would think so
 
Good. I wasn't even planning on that, just happened fortuitously to align with the fortnightly.
 
If I hadn't released my puzzle a week early it would've fit in the fortnightly :)
 
I have a puzzle ready that could be used for the unconventional tag, actually I have had it for weeks, except that it's a crossword like Alconja's (well, different kind of puzzle, but still a crossword).
 
For some reason I thought that the challenge actually started last week
I used up my idea
 
3:21 PM
No, I put my minesweeper crossword up in the middle of the mechanical puzzle fort
 
Sid
@Sconibulus You could provide a hint to that puzzle.... There hasn't been much progress...
 
Yeah, but good hints are hard to do
 
Sid
@Ankoganit Have you gone through the pigeonhole principle in maths??
 
Indeed, which is why I was glad I didn't need to put any on mine haha
 
@Sid Yup
 
3:27 PM
@Sid @Sconibulus so far as I know the only person who's thought about the chess cipher problem at all is me. I haven't given it enough thought that a hint is obviously called for. (But neither do I guarantee to...)
 
Sid
@Ankoganit The beauty in it is its simplicity. Almost intuitive at times...
 
@Sid @Ankoganit Was there some earlier discussion about the pigeonhole principle?
 
@Sid Yeah, and look, people are doing stuff like Ramsey's theorem and all just based on that
@GarethMcCaughan I don't remember so
 
Sid
@GarethMcCaughan Nope, I just asked him out of the blue..
 
@Sid oh. fair enough.
(I was just trying to think: why would one person randomly ask another apparently random person whether they have studied the pigeonhole principle? ... and not coming up with any good answers.)
(but go ahead and discuss the pigeonhole principle, it's neat.)
 
3:31 PM
because they wanted to, that's my answer :P
 
@GarethMcCaughan Umm...actually PHP is more reasonable than "meow" at least
 
Sid
@Ankoganit I second that...
 
@Sconibulus Never mind, it fitted in with board-games. Just as the problem I posted did -- the chess problem whose solution line is rather like solving a sliding-blocks puzzle, hence the unconventional combo of
 
user189275
@GarethMcCaughan Yeah, Lukas is right.
 
Sid
@GarethMcCaughan Plus my RL friends don't like to discuss Maths... Hence, I at least got someone who likes maths and is a year younger than me which helps me to revise some of the stuff I read last year....
 
3:34 PM
So what you're saying is, you're using him :P

@Sid Fair enough. Note that there are quite a lot of other mathematicians here besides you and Ankoganit...
 
@Ankoganit What about it?
 
@GarethMcCaughan ( I am not in any way a mathematician)
(just kind of a math enthusiast)
 
Sid
@GarethMcCaughan Of the same age group? I doubt.

@Sid I am sorta. (Math enthusiast, of course)

@ArbitraryKangaroo The problem with you is that you would delete half of your views and we would all get confused...

It doesn't actually. err... maybe it is a lot more comfortable to discuss with a person from similar age group than someone,say 15 years elder than me....
 
I seriously loath websites that have page-wide commercials with loud annoying music starting all of a sudden without warning and without any consent whatsoever. What the hell.
 
@Alenanno I use AdBlock Plus.
 
@Sid I don't see why that would matter for maths

"For the game of Nim, let us restrict that each player can move one or two coins. Find the winning strategy for each player." - this is one question that stumped me a year back. Maybe it is easy... I never got the answer for this. Any help?
 
3:54 PM
@RosieF I have AdBlock, maybe not plus. But this is a commercial of the website itself. Freaking annoying.
 
I despise websites that have an unclosable "customer-support-live-chat". Just leave me alone and let me browse for myself ;(
 
Sid
@LukasRotter Same here...
 
@LukasRotter Nothing like the random video/music starting and you don't know where the hell is coming from (then you discover it's a miniature video in the least important part of the page about something you don't even care about). =_=
 
It's even worse when you've just opened about ten tabs and you can figure out where it's coming from...
 
@Alenanno Then you click on it (in hope of managing to pause it) and you get redirected to another page :P

@dcfyj Luckily Chrome shows a small speaker on tabs that are producing sounds. :D
@LukasRotter :P
 
That it does, but I typically use firefox at home.
 
@dcfyj Firefox also does that.
 
No idea, I haven't used it in a while as my pc hasn't been plugged in for a few months
 
@Alenanno I just found out the other day that you can click on that speaker and mute that tab in particular
it's basically the greatest invention ever
 
I do use chrome at work, but the computer I have has no speakers so I don't really care about the little speaker icon :P

@Sid Have you tried it for small numbers of coins? If you know what happens for fewer than n coins, it should be easy to find out what happens for n. So work up to, say, n=10 and see if you spot a pattern.
@Sid or do you have multiple piles? that's a bit harder to get your head around, though the actual answer isn't super-complicated.
 
@GarethMcCaughan I've been trying this under the multiple-pile assumption, so I'll kill @Sid if it's not.
 
@Sid @Ankoganit There's some cute general theory about games of this type which makes it much easier to analyse than doing it all from scratch :-).
 
@GarethMcCaughan Wow
 
I sometimes wish we could collapse posts (comments / answers / chat messages)
@Sconibulus you can also use ctrl-M (in Windows)
 
cool, how do you use it? Is it only chat? codegolf.stackexchange.com/questions/44680/…
 
@JonathanAllan the one I linked is only for chat. If I don't find one for normal posts I might attempt to write one.
 
I don't know js what is the procedure to add it on?
Ah, FF greasemonkey I guess?
 
@JonathanAllan Yeah, I use that one.
 
@Sid If every pile is 1 or 2, the restriction has no effect, and we see that the winning positions are those with evenly many 1s and evenly many 2s.
In the general game, reduce the size of each pile mod 3, and proceed as before.

Sorry, @GarethMcCaughan and @Ankoganit ... I was just stuck up in my integration assignment.... I was thinking for 2 piles.. I did it in a single pile. I got confused with 2 piles....
@RosieF For 2 piles as well?
 
@Sid Yes. For example, 3 6 would be a good position to leave for your opponent, because, reducing it modulo 3, it is 0 0. If opponent gives you 3 5, for example, you reduce it to 3 3, and of course leaving your opponent two equal piles is an easy win (copycat).
@Sid Just thought of an easy rule for two piles which generalises a bit -- leave your opponent two sizes whose difference is a mult of 3. Oppo must disrupt this and you restore the mult of 3.
 
Thanks @LukasRotter works like a charm
 
Noooo my question just got an upvote when it had a 42 score ;( :P
 
Well it is a question so it shouldn't be 42
 
4:47 PM
can be fixed...
 
lol
 
but not by me I have it as a favourite too
if 100 people like it you get a gold badge, but if 100 favourite it you get another!
 
Sid
@RosieF Ahh, that makes a ton of sense now.... So, the idea is to just leave two sizes whose difference is 3n and you always win...
 
I think the greatest honor on Puzzling would be to get the Tumbleweed badge...
 
I don't know about honor, but it would be pretty hard to get
 
4:52 PM
@Sid Yes, that handles the 2-pile game. If you give oppo 2 piles whose difference is 3n, oppo can't preserve that property (not allowed to take 1 from each pile). But if oppo gives you a diff of 3n+1 or 3n+2 you can take 1 or 2 to restore 3n (or 3n+3 or 3n-3).
 
Much easier to get when there are few people.
 
It only asks for 0 score, so a few sockpuppets will guarantee that at least.
Or does the score have to be consistent?
 
It asks for 0 score, no answers, no comment, and low views. That a lot of factors
 
unsung-hero would be neigh on impossible puzzling.stackexchange.com/help/badges/51/unsung-hero
Gold too
 
The 24th and 25th of december are both on weekends this year, I guess that would be a good time to post it.
 
4:56 PM
To try and get a tumbleweed?
 
I'll make sure to leave a comment on anything you post then :P
 
@RosieF nononono, you're not supposed to just tell them the answer. Where's the fun in that? (For them, I mean.)
 
How sad, I think this would've been qualified for Tumbleweed, but I guess one of that "Possible duplicate of" comments was posted ;(
there are 9 of them (didn't check views because I have no idea what qualifies as low), and all of them failed for the same reason...

Q: What constitutes a "puzzle," exactly?

Challenger5Sorry for posting this, as I am sure this has been asked before, but what exactly makes a "puzzle?" For example, what if posted a puzzle like this: I am the lowest number for which the Collatz conjecture does not hold. Who am I? Obviously this is a mathematics problem, so it is not a puzzle...

Q: Simply Riddleculous

Beastly GerbilAn entry in the 19th fortnightly challenge to which I have been assigned riddle + number-sequence by Alconja Alright now, you should listen close. A number sequence, lets see how it goes. But of course, I'm not going to tell you. Care to wait and I'll sell you a clue. Even when you ...

 
@Sphinx Hmm... is that really a riddle?
 
@Sconibulus I hope so....
 
@GarethMcCaughan strikes again!
 
I spent 20 seconds adding it to the fornightly challenge and when I'd finished it was solved. Too easy?
 
Apparently, but I didn't really look at it to solve it, just kind of browsed it.
 
5:36 PM
I suppose the letters might have looked suspicious , AABCEHMU
 
@BeastlyGerbil All I mean is, the text doesn't really clue the answer, it's just a way to finish the lines the Steganography started
 
@Sconibulus it does give clues, 'look before' and 'can't go on any more'
Needs previous numbers and can only go up to 21
 
if you look at the tag, I'd say it fits.
 
The letters did indeed look suspicious, for what it's worth :-).
 
@BeastlyGerbil Yeah, I first noticed that the lines were alphabetized. That's what gave it to me.
 
5:45 PM
I couldn't think of anything harder :)
 
The difference of primes sequence?
At the least it wouldn't have been alphabetical and it could've gone on longer
 
I suppose I could have done a harder sequence....

Q: The friends dilemma

SidSo, some of my RL friends think that I am a mean, arrogant, know-it-all jerk. So, I decided to prove them right. I gave them a note, and told them that it contained something related to my favourite movie. Incidentally, not one of them knew my favourite movie. So, with a smug smile on my face, I ...

 
Sid
@BeastlyGerbil Yeah, I stole that line from Alconja...
