The Sudoku puzzle format consists of (usually) a 9 by 9 grid that must be filled with numbers. The classical Sudoku rules are as follows
- Each row must contain all of the digits from 1 to 9, with no repetitions
- Each column must contain all of the digits from 1 to 9, with no repetitions
- Each sub square (3x3 grids marked by bold lines) must contain all of the digits from 1 to 9, with no repetitions
The historical inspiration of Sudoku begins with the Latin square, a type of grid problem similar to Sudoku in that it consists of an N by N grid where N digits (or letters) must be arranged in accordance with rules 1 and 2 of Sudoku (the sub square had yet to be invented). The first known example of a 9 by 9 Latin Square is from a monograph over 300 years ago, written by the Korean mathematician Choi Seok-Jeong. However, the Latin Square was popularized in the west by the legendary mathematician Leonhard Euler, who independently invented it almost 70 years after Choi Seok-Jeong.
According to Christian Boyer (idk who this is), on July 6th, 1895, the french newspaper La France published the earliest known example of a “true” Sudoku puzzle following all 3 rules of modern Sudokus, although french newspapers had previously been publishing similar (but different) puzzles prior. The name “Sudoku” itself (meaning “single digit”) comes from Japanese magazines in which the game was popular during the 80s and 90s.
In Modern times, the Sudoku puzzle scene has been blessed with the addition of numerous variants, that add on additional rules, elevating the puzzle. The puzzle in the provided image is one such example, known as the “miracle Sudoku”. It comes with 3 additional rules on top of the 3 original.
- If 2 digits are separated by a knight’s move in chess, then they cannot be the same
- If 2 digits are separated by a king’s move in chess, then they cannot be the same
- If 2 digits are adjacent (left, right, down or top, none of the diagonal directions), then they cannot be consecutive (ex - 5 and 6, or 7 and 8)
As can be seen from the fact that only 2 digits have been provided to start with, modern Sudoku authors are big fans of making puzzles that appear to be impossible to solve. This of course, is my favorite part about modern Sudoku. If you want to try to solve the miracle Sudoku, here is the link.
Some of the other example variants add new rules, such as German whispers, Dutch whispers, Renban lines, Entropy lines, Thermometer lines, killer cages and many more. You can find a massive collection of these puzzles on the logic-masters website.

Can you bump me to the week of the 4th? I will be mostly offline the 28th and that week and I don’t want to be thinking about writing/posting a mega because I will have other things to be worrying about.
that works, i’ll rearrange some stuff
I’m gonna go again.
sounds good, i’ll put you on
Been practicing with my tablet again after taking an extended break. It’s a bit of a learning experience to draw without looking at my hand. Although the curves aren’t as smooth as I’d like, I think I’m getting better.
tonight's practice
I remember the last time my friends came around on their bikes without texting, unannounced, just to see if I was home and wanted to hang out. 2008, we had basic cell phones (parents got us them, we were out a lot alone, older teens). At the time I didnt think that would be it, but it was.
I dunno if I miss it, per se. But the spontaneity and closeness was nice. Everyone switched to text first before coming by for a reason though - it did suck to go somewhere and they weren’t home or couldn’t hang out and people were busy and so on and so on.
I really wanted to both do nothing today and play yakuza like a used to but couldn’t do both and settled with my chores in the morning before cuddling with my plushies in bed all day listening to iceburg vids. Don’t know if I wasted the day necessarily since I chose to do it but yeah. Week days are for studying some more until I find a job and weekends are my time and even spending the day on me feels good.
ranting and raving about IDEs
i like neovim more than other editors but i would like it more if my stupid plugin manager let me configure on a per project basis and i didnt have to fuck around with tabstops and line endings all. the. time. arghhhhhhhh. say what you will about IDEs (and there’s a lot to say) but at least you dont have to fuck around with this shit constantly, forget the setting names and have to dig through documentation to set it up/fix it every single time you come back to a project. I’ve spent more time fucking with tabstops and line endings than I have actually writing code. Such a gigantic pain in the ass. My take on editors is that I hate them all except emacs bc i’ve never used it and I’d probably hate it too for anything other than tiny LISP progs. I just want a lightweight and fast terminal editor with syntax highlighting/errors in the current files I have open, symbol lookup, and an easy way to hook up to a debugger. thats it! I don’t need git integration! I’ll use the fuckin cli! I dont need AI bs! its crap! I don’t want to manually disable half my plugins when i switch to a different language and still load every lsp for things i’m not even using! I just want it to work consistently, require minimal configuration and get the fuck out of my way so i can write the damn code. fuck!!! people hate on the godot code editor cause it doesn’t have multiple buffers but damn if I havent gotten more done just because i dont have to fuck around with the settings all the time
Does… Does anyone else hate pride? Its pride here… I really dont like it, it just feels like another opportunity to be excluded by my supposed community, another opportunity to be told “everyone fits in here (except you)”. Despite what all the people around me seem to say, there is no trans community, no queer community. Theres just overlapping social groups… That im not a part of and either dont want to be a part of or am actively excluded from. I have my friends. Most are trans or queer. Thats enough. Pride is for the acceptable people, not me.
Finally added my trans cousin on insta, they just posted a mao meme about killing landlords
and have they/it/she pronouns We haven’t talked in so long and I really badly want a friendship with her… so bad at making new friends though…

Rough family experience
Went to the museum with family. Tried to hang out with my brother and their partner, and a friend that I kinda like. Other queer/neurodivergent people
But they all like slid off as a group and I was stuck by myself because I didn’t want to walk around with my parents
The easiest shot I could ever have to make friends and of course it doesn’t work out. Nobody even understands or cares that I felt left out. They described it later and were like “yeah the three of us did our thing” and it’s like, I wanted to be part of that. They didn’t even consider me.
Clearly I’m just too quiet and nice and polite to live. I care too much about others and if they’re feeling good or enjoying themselves. I want things to be peaceful too much. These are flaws.
What’s more I’m worried that there’s more knocking around in my brain besides being gay and trans and autistic. Another secret thing that makes people not like me. Idk.
It’s not going well, and I’m busy, and I’m too fucking weird for the weirdos in my life. So idk.

That sucks :/
I wish I knew you in person, Id scoop you up and take you places. We could get pizza at this crunchy vegan punk bar downtown. Or go to a bug museum. The leaf mimicking bugs are kinda funny there, they mimic the wind yet are in enclosed glass (so there’s no actual wind).
You struggle so mightily and put such a good effort - and Im really sorry for this lol - but you are actually brave every time you try stuff. Cause I know from what you’ve said how it makes you feel to make these efforts!
Maybe its harder with family to enforce those boundaries of “Hey! Include me! Don’t just walk off it’s kind of rude to abandon me!” Just cause those dynamics are probably very well worn in. I hope you find your group, you do deserve a nice group of people to hang out with.
CW: Joy killing
My mom has actually figured out I am genuinely unhappy being with my parents despite my efforts to hide it. She confronted me about it and I was just, stumped. Didn’t want to admit it, but my silence spoke volumes.
My little brother is in a terrible mood these days and doesn’t respond well. He also has too many temper tantrums which drain the emotional energy of the family.
My dad, I just feel sorry for him, he seems to be a struggling with a family that doesn’t kinda care about him.
Yeah, I’m remembering now why I was so eager to leave, and why I had to leave before my relationship with my parents healed.
I know I shouldn’t blame myself, but me being trans and repressing (then hiding) it for 10 years at this point has driven the family to dysfunction. It’s just a fact. Any hope for a healthy family dynamic is permanently dead. And I don’t feel at all like I ever want to come out to my parents, not because I’m even afraid anymore, but because the emotional disconnect is irreparable.
Also, I will just say it. I’ve grown up to be a nihilistic, sadistic and self-loathing type of person. And I say none of that in a romanticised way. I’m niethzche’s last man (or last woman) (I refuse to spell that fascist’s name correctly)7

I’ve grown up to be a nihilistic, sadistic and self-loathing type of person.
The broke hating yourself vs the woke hating others (my recommendation)
Also fuck your family, honestly dgaf. They’re just people you happen to be related to. Since we already know most people suck
the same holds true here tbh. When I don’t need mine I intent to have as little contact as I can get away with. They might be able to help me out financially if I got in a bind or I’d definitely consider dropping them completely tbh. Also its not your fault its theirs, they’re the dipshits who forced/pressured/whatever you to repress for a decade.Also
sadistic
Most people want to torture me so
I hope the same for them. They’re the ones with power anyway. Could probably list more people who should suffer but I think that’s enough. I simply want what they force on me. They don’t want to pay for my reconstructive surgeries, they should need and be denied reconstructive care. Fuck em. Burn in hell. I hate the fuckers. So many fuckers I hate. I don’t like hating most humans but they’re mostly deserving of it. They deserve every bit of suffering they’ve inflicted on me.
If you read my rant, thank you for being my virtual therapist. I cannot afford a real one.
I just received word that hexbear admins will ban all users who don’t know how to play sudoku
Good riddance
okiiiii there was some trans gaym about like… the mc just waking up one day with an alien or something in her chest and the art was like amazing and we cannot remember the name of it at allllll so if that rings a to anymany can u tell us what gaym that issss…
Where the fuck are all the cute trans guys at???
Looking for cool rocks, bugs, or fungi outside. Or inside having a bad pain day (every trans guy I know has some kind of chronic condition 😭)
They are all waiting in line to ruin my life, please make them go away I’m not even joking 😭😭😭😭
I can train them
touching grass
Get off of the grass!
And into my car!🎵
I’m now realizing a pattern where I move to an area and within a year the local mall dies
Those mall goths are having their habit destroyed little by little
in order to survive, they must adapt (evolve into strip mall goths)
I’ve seen one the other day doing activities for kids at the library, a cool habitat I think.
Honestly real cool seeing people play board games with kids and how happy they are. Libraries prob last free spaces around and I love going to them in my free time.
same tbh, sometimes I go to just to hang out and read for a couple hours, even if I’m not borrowing books. It helps that they always have magazines I like but would never pay for because I’m cheap lol, like harper’s or scientific american
I need to check the magazines out now, I remember liking the ones my college library had like the psychology ones and thinking maybe one day I’ll get subscription but also being cheap.
Opening drink cans with my long ass nails makes me feel really femme and I love it
