This is a Pentominous puzzle. Rules of Pentominous: Dissect the grid into regions of 5 cells each. No two regions of the same shape can be adjacent (but they may touch at a corner). Rotations and reflections count as the same shape. Each given letter must correctly label the shape it is in. (An...

Q: The Hungry Good People

So, there are these 5 good people. They have 5 bowls of roast chicken (one per each). They also need to use both a spoon and a fork to eat it. Only two people have one pair. They also are going to hold an African Children Awareness Program, and of course, they need not be late. They need 3 second...

As a consequence of how wide-open my pun crossword is, I sorta hafta make it a "Something Different". Credit to Deus for introducing me to this genre.

(obviously I don't have to, but I don't see another good way to fill in the long words and make me feel legal)

@Deusovi re: puzzling.stackexchange.com/questions/102421/…

This feels like a nurikabe!

Deusovi

@bobble yeah, wide-open crosswords are pretty rough - Something Differents can be a lot of fun though, provided you lean into the weird answers as hard as possible

@Avi it has some similar "how can this region fit"-type logic, yeah! statue park is another good genre for that kind of thing - it's easily one of my favorites

Avi

more of an intuitive solve after I guessed the bottom right

bobble

@Deusovi I don't know how weird my answers are - mostly I'm just doing 2-3 words that combine to make me laugh

Avi

I have a lot of practice with visualizing pentominoes from a game like this

bobble

that looks neat

Avi

3:56 AM

also, 4-color theorem, lol

Deusovi

what about it?

Avi

I could've colored my answer with 3 colors

Deusovi

ouch, the red and green there are very hard for me to tell apart

and I was looking for an answer with the actual logical path, rather than guessing

Avi

D:

all I can say is that

bottom center P is forced

looked like the bottom right corner could be a p

after trying to place it higher, brute force didn't work out. so I placed the bottom right P and a line connecting the two Ps to the upper-left of that

that gave me the P

and a T

bobble

Why don't you add this to the answer?

Avi

4:02 AM

I will - once I'm done typing it out

you can't put an L there because then the P on the bottom left forces a touching L in conjunction with the P on top of that

thus, giving you the top left P (because you need to maintain connectivity of remaining pieces

Deusovi

there is a clean logical path where you shouldn't have to bruteforce anything

Avi

hmmmm

Deusovi

hm? there are no connectivity rules in pentominous

Avi

no like

there is connectivity of remaining pieces

basically you're looking for a clean 5-piece region like the T

or a longer region that will contain multiple pieces

in which case, it should be a region that is a multiple of 5

placing the P any other way will force 2 adjacent Ls which is invalid

Deusovi

you should probably put this in the answer, rather than here

Avi

4:06 AM

yeah

in all honesty I'm probably going to delete the answer

I don't have enough interest to explain it all this time

and it's probably more hurtful than helpful to other solvers, to have the full answer in front of them

bobble

will you put it back up later with explanation?

Avi

if it's still available

i'm going to bed soon

but yeah basically the puzzle is like, half "to P or not to P" and half "hmm hmm so can this go here"

bobble

"To P or not to P" - say in an overly-pretentious voice for maximum effect

Avi

That's not a question

anyways, goodnight

i think the exeter museum could be the RAMM (royal albert memorial museum), or maybe the AIM (american independent museum) which is in a different exeter

@Avi yes indeed, that is the question

Wow - I have been using this site for so many years and actually didn't know there was a chat... I feel like I've just climbed up on a mantlepiece and pushed through a mirror. Or possibly just feel like an idiot. Whichever. :/

Thanks! But I may just fade back into obscurity where I can't do/say something stupid (again!) :P (Also thank you @Deusovi for the patience to let me fix my terrible solve path images...)
