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.

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…
Its your cousin right? Should work out okay
Yea, that doesn’t mean I’m good at building or maintaining relationships though. Especially because I don’t know what we’d do together- idk if she games, we live very far too so real life hanging out is impossible. idk.
I build relationships and friendships by doing stuff with people! Hopefully you can both game together, that’s a cool idea.
If it doesnt, its your cousin right? You could call it or zoom or whatever. I dunno if its a social faux pas to call people on their phones (not making a joke, I suspect its considered one cause my gen z little sisters are bewildered when I do lol), but I still call my friends out of the blue and chat every once in a while to keep up. Tell them I love them. I think you crossed the critical threshold by being family, let’s you have some automatic familiarity - hopefully enough to text or game or call or video chat.
That would be so nice for the both of you to have each other! None of my cousins are trans, a few are still in the LGBT otherwise, but Im the only transgender person 😫
I know that’s what I need to do, but idk. I have tried that with some people and I think we both wanted it to work out, it just didn’t. That recent falling through has had me feeling pretty bad about it but I guess I haven’t really talked about it. Hope we can game because I literally don’t know what else there is over the internet.
Yea we could. tbh I haven’t had much to do with them for years at this point, really haven’t seen them since we were kids. Just distance mostly. It kinda is among gen Z, I would find it very weird and kinda concerning if one of my friends called me out of the blue, or tbh wanted to call at all. I hope so too, need to send the first message. I’ve been trying to workshop it, I’m not really sure what I should open with or when I should tell them I’m trans. I want to early but I don’t know. Its very hard to decide what to say sometimes, especially when its something new like this…
Damn :cat-trans:
