i'm having to laboriously place numbers all over this thing so i understand RC notation

so i have to fill 3 more squares around the 6?

bobble

you should be able to place 4 mines with "can't have run of 5" logic

Sciborg

R3C5?

bobble

yep, mine

Sciborg

R5C4

and R5C3

bobble

yes, mines!

Sciborg

00:04

arrrrgh that took me so long

now you said there's middle logic?

bobble

yes, now: where can the 3's final mine not go?

keep in mind the 2 and that it must be part of a tetro

Omega Krypton

cool puzzle right there

bobble

upvote it then :P

Sciborg

it can't go in R6C5, because it would be by itself and couldn't connect to a tetro.

Omega Krypton

where

bobble

00:06

Q: Wait, so how many mines are there? A tetromino minesweeper

Here's another tetromino minesweeper. I have bolded where the rules differ between this one and my first tetromino minesweeper 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 tetro...

Sciborg

same thing for R5C6

bobble

hehe thank you

Omega Krypton

:)

Sciborg

so i've placed non-mine squares in R5C6 and R6C5

bobble

now, there's one more you can place

consider the 2 in R7C7

Sciborg

00:09

ohh, yeah. R6C6 too

and now i see... more deductions

bobble

see you are smart!

Sciborg

I only needed patient hand holding and constant hints :p

merrybot

you are one heck of a smart baby bird

Sciborg

the next deduction is with the 4 right?

bobble

yep!

Sciborg

00:11

mwahaha

merrybot

was thinking of making a slitherlink/minesweeper/something where the numbers are pi in base 8

bobble

did you find the global deduction yet?

Sciborg

I'm not sure but I figured out the 4 stuff and placed the S!

bobble

there are two intended global deductions, though you can sorta skip over the first

Sciborg

With the 4 logic there had to be a mine at C6C8, and then because i already used one of the L-pieces so we couldn't have two forced L-pieces, it had to be the S-piece

bobble

00:17

yep, that's the global deduction

"too many Ls"

Sciborg

i double-checked it with deus's answer to be honest

bobble

it's why I have that initial deduction with the L that's mostly separated from the rest

ThePuzzlingPlatypus

I'm waiting in the Contact room, but I'd be up for codenames too

ping me if either of those games happen

bobble

I am tutoring and I have homework after

Sciborg

I have Among Us planned in a bit

ThePuzzlingPlatypus

00:21

OK that's fine

Sciborg

so i'm here now, bobble:

where do i go next?

bobble

2 in R7C5

and the 2 next to it, for that matter

Sciborg

Gotcha

i imagine you being a little bobblecrown sitting on my shoulder, going like "look over there now"

bobble

in The Sphinx's Lair, Nov 9 at 17:38, by Sciborg

Sciborg

equally accurate

can you give me a hint on the intended deduction with the 2?

i filled in a few more squares but i haven't placed the mine

bobble

00:29

so it only has 3 it could have mines

Sciborg

right

bobble

so if any square isn't a mine, then the other two must be mines

Sciborg

yeah

bobble

test the bottom one and see if there is a contradiction

Sciborg

OHHHHH

there we go

bobble

00:31

I loved how much I reused the same global deduction :D

Sciborg

so like this, right?

bobble

yes, now some extension & connectivity logic should help

Sciborg

and after that, i can place the S and T now, right?

bobble

picture?

Sciborg

bobble

00:37

yep, that new S works!

Sciborg

Huzzah!

bobble

also tutee ended the session with a teary thanks for explaining the math better than teacher, so I am feeling very smart right now

Sciborg

awww <3

bobble

you are deduction-ing well?

Sciborg

still good?

bobble

00:40

yep!

you're getting close to the point where the final global deduction kicks in

Sciborg

heh, wait a minute....

i have the ten locations, don't i?

bobble

you do!

that's the final global deduction

Sciborg

but which ones go where, that's the question...

bobble

> And hey, wait a second...

that's from Deus's answer

Sciborg

well, i know where the O goes at least, because the other three locations can't have it

hmm

yeah, and then the top right has to be an L

it can't fit an I piece, so the other two are I pieces

bobble

00:46

yes, yes, yes!

Sciborg

voila!

bobble

um no

Sciborg

no? wait

bobble

all ? have to be different numbers

you have two ? that are 4

Sciborg

what???

wait, was that a rule??

bobble

00:48

> Each represents a different number.

Sciborg

oh, so the L is wrong

voila again?

bobble

voila!

was it as bonkers as promised?

Sciborg

that took me so longgggggg

it was bonkers

very fun

bobble

:D

Sciborg

i need to lie down :p

bobble

00:50

any favorite deductions?

Sciborg

the "oh wait, i know where all 10 pieces go" was really funny

i'm proud that i solved this 60% by myself

bobble

and you got that one by yourself!

Sciborg

yeah! :D

That's such a fun puzzle

i'm glad i went back and did it properly

Thank you for the patience

bobble

most of the deductions were actually by accident, I set up the starting ones and then the numbers forced a bunch of others

thank you for being with me last night

that um sounds a bit wrong out of context

Sciborg

<3

it's okay i'm g a y

which also sounds bad out of context, oh dear

bobble

00:54

context matters

Sciborg

the point is we're platonic crown-hat friends

bobble

one makes puzzles, the other solves them

Sciborg

*and we're both definitely straight we promise

bobble

and cis and white and abled

Sciborg

for sure 100%

nothing to see here

we are fine

bobble

00:57

everything is fine

Sciborg

i'm super super neurotypical and normal

all is fine

i swear we need a therapy chatroom

bobble

there's the monologue room

Sciborg

you mean the monologue and therapy room

bobble

and I hijacked the Grove yesterday for therapy

Sciborg

it's like the SHIELD thing except we're the ones who need the therapy

bobble

01:01

i make puzzles during physics class and help moderate a puzzling site during econ. what's not normal about that?

Sciborg

totally normal activities

bobble

I spent 15 minutes yesterday transcribing an image for Lit because it made that tiny corner of the internet more accessible.

Sciborg

appreciated <3

bobble

do you want a ping when the sashigane goes up tomorrow?

oh also did you have a chance to review the PSA?

Sciborg

Definitely!

And I was reading through Gareth's comment about it but didn't quite finish

I've hopped into Among Us with my friends but i'll keep you open on the side when i'm not imposter

bobble

01:05

so never

Sciborg

hehehe

it's decided randomly, but i really love being imposter

i hope i get it

are you going to make the PSA or are you second-guessing it?

bobble

still second-guessing, I wish Gareth would edit it so he could put his suggestions in

Sciborg

I think he had a pretty insightful comment, it makes sense

bobble

do you want edit rights?

Sciborg

I think you, deus and gareth are probably the most helpful writers on it - i'm not sure what to add

Excited for your sashigane :D

bobble

01:11

I traded an easier break-in for some interesting middle and end logic

Sciborg

02:09

Hey bobble

You're my favorite bobblecrown

Just thought you should know

bobble

aww

wait do you know any other bobblecrowns? side eye

Sciborg

the sample size is one, but you're still pretty great, so

bobble

well, you're my favorite gentleperson
