Trichain is a new puzzle type I invented. It is somewhat similar to Nurikabe, but it uses a chain of L-trominoes instead of a continuous wall. Example puzzle with solution: Rules: Numbers must be white, and match the size of their white islands. Each white island can only contain at most one n...

CCCC hint: The first letter is S.

My next puzzle is ready, but I'm holding off posting for now as Bubbler's grid-deduction has not been solved yet
... and it's solved

oh nooooo

Got you covered...

i didn't realize that you could cover a 1 square
in 2 different ways

Should I just post mine? Or still wait?

@Avi Yes, it's one of the fun parts of the puzzle

12:36 AM
so I tricked myself

If I post now, Jeremy will be less able to solve it, giving others more of a chance

otherwise I had the 2 pattern figured out
idk
do what you want

post now, I guess. Time for final grammar check

@Avi I originally had the lower left and top right corners like that, but it was a red herring.

I decided to make another one of these, because they are fun and this one is rather different. Can you place all numbers from 1 to 16 into cells, such that the following 8 equations hold? Note that the operator "/" only works for non-remainder division, i.e. you can have "8 / 4" but not "8 / 3". ...

This is a minesweeper puzzle with a tetromino twist. The goal is to place mines in the grid, following a few constraints. Rules: A number indicates how many adjacent (including diagonally adjacent) cells have mines in them. Mines cannot go in numbered cells. Mines must be grouped into tetromino ...

@GarethMcCaughan oh no.. seclusive ain't correct, secluded is closer but has only eight letters..
"right letters"???

letters that are not on the left
I'll be off for a bit as well.

1:37 AM
@JeremyDover, @WhatsUp, what did you think of my tetromino minesweeper? Were the deductions interesting and/or hard?

I liked it! Was doable, but definitely had to put my thinking cap on. Thanks!

I was pleased that WhatsUp followed my intended solution path almost exactly. Not sure how your path differed.

^ Same for Jeremy's solving path for mine

@bobble looks like Avi just poofed without smoke

that's no good. smoke is very important

1:45 AM
@Bubbler Seems new to me! Reminds me of the puzzle type Dominion:
@Anonymus25 hello!

@Deusovi image isn't working

now works

@bobble indeed

Oh, that's pretty cool.
(without the knowledge) I did consider using dominoes too, but it seemed too hard to set up with the white areas, so I went ahead with L trominoes.

1:51 AM
I think domino Nurikabe might be more logically interesting (but harder to construct)?
seems to me like it could allow for larger deductions

Look! We're using the Puzzling.SE main chat for chat about Puzzling.SE! This is weird.
For my tetronomino minesweeper: I liked how many deductions I could force that were just "can't re-use a tetromino". There's a LOT of those that are in the intended path.

just did your puzzle, Bubbler - I wonder if there are any interesting global break-ins you could make with this ruleset? it seems to rely a lot on 1s and 2s

@bobble Sorry, I just see your message. It was interesting (which is the reason that I solved it), not very hard. It mostly feels like a usual minesweeper game.

I'll try to make a harder one. Thing is, I don't have much experience with this genre, which limits the kind of deductions I can force.

However I wonder whether this kind of puzzle could be made in larger scales. With tetronomios, the scales seems to be limited, as there are not so many of them...

1:57 AM
@Deusovi I'm trying to come up with one that uses fewer 1's and 2's.

@WhatsUp I considered pentominos, but that would make the grid really big

you could also do two of each tetromino (with reflection)

That would sound very exciting!

That's an idea. The grid would still be bigger, but hopefully manageable.

I'd also be interested in seeing a Statue Park puzzle that used minesweeper clues... that could be interesting too

2:00 AM
The puzzle started as me being stuck during making a pun crossword. I'm happy to keep procrastinating on that :)

4*14 = 56 ~= 5*12 = 60, but you could duplicate only a few of them, like some Battleships with different number of ships

you could also do 4×10?
just use the 5 tetrominoes, not counting reflections as different
that's the usual piece bank for statue park puzzles at least

user478740
Is anyone still interested with the Falcon Circus series by @iiiidk?

user478740
I found it and it still seemed unfinished

@bobble truly truly

2:03 AM
I think I'll take Deus's suggestion. Does a 12x12 grid seem like a good size?

@Anonymus25 That seems to be a very old series, and they haven't been online for over two years - I wouldn't expect it to suddenly revive

I think the answer to the cccc may be SOMETIMES ("only occasionally") but not sure on the wordplay
deusovi pls save

don't see any way that could work at the moment
not saying it's wrong, just that I'm not seeing anything

fair
it was worth a shot, though

I thought of that too (also you're back)

2:06 AM
yes i have unpoofed

in case you don't wanna backread, bobble wants you to choose a type of color smoke whenever you poof again
Which color will it be

I poof with yellow smoke because I'm a yellow crown

purple smoke of course

makes sense

(also, it's been months since I worked on making this crossword. Hopefully it will be finally released this month.)

2:08 AM
want help?

lol

2:38 AM
Question: does tense matter for verb cryptic indicators? Specifically, is "Broke, I leaving Iran (3)" preferred over "Broke, I left Iran (3)"?
(not in terms of surface but the correctness of the wordplay)

From a wordplay perspective I think both are considered fair game. But the former has surface problems.
You can't fix it as "I leave Iran", because you would want to interpret as "the letter I leaves Iran"...but then "I leaves Iran" has surface problems too.

also not sure how the definition("broke", I presume) would match up with ran

Definition number 2

I kinda see it in the "broke away" sense.

breaking away I guess
as in, running away

2:43 AM
But I think it would be too stretchy for me.

but it's a super uncommon use of the word

^ what Avi said

hmm never knew about that hahah
I'm only basing on the thesaurus since I don't know (and in fact it has an example using "broke" instead of "broke away"). But again, I myself ain't that knowledgeable there
In any case, I'd love to hear what @Deusovi thinks about my question as well (if you have the time :0)

as for the grammar of the indicator... I would prefer the former, yes, but I don't think I'd be too picky about seeing the latter

yay
thx for all the inputs too
I just want to put this unfinished crossword to rest
I started in June, and... yeah, my laziness got the better of me :P

2:54 AM
My idea for statue park-tetromino minesweeper hybrid: whenever a mine is on a statue park dot, that dot switches color
I am nowhere near experienced enough with either puzzle type to make this happen, so I will leave it for later.

oh, I was just talking about regular Statue park rules, but there are also Minesweeper clues in the same puzzle - not two separate puzzles

hmm, also an idea
too many ideas!

I just got a (seemingly) working Trichain without any 1s and 2s, though the logic is IMO not as clean as the first one

This is a Trichain puzzle. The rules of Trichain are as follows: Numbers must be white, and match the size of their white islands. Each white island can only contain at most one number. Some white islands may have no numbers. Black squares must be part of L-trominoes. Black L-trominoes cannot b...

@Bubbler I solved yours just fine but I seem to get (at least) two possible solutions for Avi's.

@wl Do your solutions to Avi's agree with my partial solution above?

Looks like it.

Hmm. OK, I think I got the two solutions too, with a lot of trial and error (flipping trominoes around and around until the left lower 10 is satisfied)

Bottom right is underclued for me.

The bottom right tromino can be flipped, right?

Yes

For the C4, I wonder if the definition could be "only occasionally composed", for something meaning "half-mad" and starting with SEMI. But I'm not (yet) seeing anything along those lines in the rest of the clue.

coincidentally, the reverse of semi is imes, which are the last four letters of avi's suggestion ("sometimes"), but i don't think there are reversal indicators in the clue
wait hold on
im hoping gareth isn't pulling a pun in this clue and that my thoughts are wrong

Nurikabe and Tapa puzzles have the interesting property that the target shading is identical for both: a fully-connected shaded region with no 2-by-2 blocks. The difference is the cluing, so there seems no reason you can't use both Nurikabe and Tapa clues in a single grid to clue a single shaded ...

And here it is. After I posted the question concerning the Fortnightly Topic Challenge, I found a chat where many people miss these challenges. And, the last challenge was in 2018, so since we have the pandemic, this is the perfect way to kill some time during lockdown. @Lukas rotter has agreed t...

2:30 PM
I just got back online after waking up. Are we actually having Topic Challenges again?

whatâ€™s a topic challenge?

There's a theme, and people create puzzles around that theme for 2 weeks
This one's my favorite, where all the puzzles had to have xkcd titles

@bobble I guess so. But I don't know if the current post by anon will go through since they just decided the topic on their own and the format is really non-standard.
And the post was pretty impulsive, considering the discussion thread about whether or not we should bring them back was posted 8 hours ago...

hm
anyone up for c4 solving?

3:07 PM
Calling @/c4 solving experts cuz I'm not one of them heh

@PuzzlingMeta Seriously?

I've already put a complaining comment saying to wait a day out of respect for timezonse

@bobble I mean, can you do that? Just propose one and right afterwards declare it as the topic challenge with no community consensus?

It's not how it has ever (ever ever) gone

you can make that meta post, but it won't likely be accepted as an actual thing

3:12 PM
I think they thought that since 2 other people gave supportive comments on the first post there was "community consensus"

@bobble Yeah, pretty sure that's NOT how it works?

I'm pretty sure as well

@Lukas rotter, you will have the job of giving the candidate questions that join the competitions. I will give out the challenges. — Anonymus25 3 hours ago

@Deusovi I think perhaps they misinterpreted Jeremy Dover's comment?
If you've got @Stiv on-board, you know you'll get at least one quality puzzle. If you have an idea for a topic and are willing to do the legwork, I suggest you just send it. I'd rather spend time trying to write a puzzle than talking about whether I should be thinking about writing a puzzle. — Jeremy Dover 2 hours ago

possibly

But then Stiv clarified in the following comment so I don't know

Stivs comment was after it already happened

Each rational root of a polynomino is in a certain set
of p/q
where p is a factor of the highest power term's coefficient

Right
Thank you

3:26 PM
and q is a factor of the constant term

@LukasRotter Weirdly though, I hadn't spotted the other post at the point I commented, so my comment was written after the event whilst thinking it was before the event... (confused yet??) I also think an arbitrary choice of Wednesday-Wednesday dates is not the best idea. Wasn't it Sunday to Sunday last time? A much more natural way to divide up the calendar...

oh wait switch p and q

@bobble No, I know what you meant
I just needed a quick refresher on which theorem that was

Hmm...appears I may have been too encouraging about moving forward with the fortnightly challenge.

alright @bobble ... i thought "surely js could make this easier?" i was wrong

I mean it could. but it makes it more complicated

right, and i failed to realize that

4:18 PM
But serious question, since the post is out there: if you agree with the idea of reinstating fortnightly challenges, why not use this one to get it started, and then refine the selection process for the next one? It's not like the proposed topic is pickles or anything.

> it's not like the proposed topic is pickles
of course it's not, the meme is basically retired now

That's what makes it funny?
;-)

i see now

I don't have any ideas for this topic - if it had gone through the normal process I would've been able to participate. As it stands I probably can't.

Fair enough, and I'm not saying that this should be a model for the future...but it can be impetus to get started (often the hardest step). Maybe in parallel, we can work on how to generate the next one with a broader consensus.

4:34 PM
I guess we should use the Rerun Thread again. A Re-Rerun might be a bit confusing ;) But of course we have a view "outdated" suggestions...

a *few?

sry, yes

4:48 PM
@Bubbler yikes!
it could be fixed by moving the 10 1 space to the right
but not sure if that makes deductions fail
is it better to fix it now? or just post another one that's not incorrect :(
hmmmm
probably better to just accept it the way it is
and do better next time >:c

When I've had mistakes on puzzles in the past, I always make sure to leave the old version and post a corrected version. Someone may well want to solve it in the future!

5:07 PM
i give up w/ my converter ... just too much for me

@bobble ^^

got it.

:(

one fun thing I did was make a command-line calculator in python
you have to split an input into numbers & operators and then resolve the operators in order
you can try!

i mean you could just put it into eval()

the point is to make it work by yourself

5:21 PM
so something like (typing...)
```eq = input("type an expression with +-*/\n")
# fancy stuff```

yeah

i'm really a novice pythoner though so uh
blegh

you can make two functions, one that processes the string input into a better form (a list, for example), and one that processes the array into a result

so like i'd have to separate the operators from the digits

yes
and get rid of spaces

@JohnDvorak because that's only the consonants.

with what constraints?

sure, then stick vowels at the end

@bobble only include the rows and columns that are necessary.
