Is it just me or did anyone else thought at first: Extra rules makes it even harder, but actually that rules out a lot of possibilities and makes it easier.
Extra rules always makes it easier. The less possibilities the more you can say for sure to rule other possibilities out. Especially if you can write down the possibilities for each unique square.
this is proof that you can put anything on youtube if you help your audience follow along. Oh that was so beautifully resolved :) Well done. I never heard of these extra rules.
Actually try it before thinking so poorly of yourself. You might be surprised. And, if not, just remember all of these skills are learnable, not some magical natural talents. ^_^
This was the first CTC video I watched during the summer of 2020. I stumbled upon it simply because it had shown up as a recommended video despite having never watched a sudoku video before. I clicked it, I regret nothing.
Exactly. At first I was very skeptical when just seeing the board with 4 numbers, but those additionnal restrictions are actually huge clues and tremendiously help in solving it. Not saying it's easy, I'm no Sudoku expert (I don't really like them). His software is pretty nice though! Taking notes like this in real life is more... messy haha.
Thats one of my favorite principles of game design, you cant always mark the end of the level with a reward, you can spice it up by showing the player where NOT to go (I know it sounds stupid, but once you have it in your mind you realize how many levels could be upgraded with that phylosophy)
In fact, the three added restrictions (diagonals, knight's move, and magic square) made this sudoku much easier to solve than most regular ones. There wasn't even a single mention of any type of "fish."
It wasn't this video, but I remember watching my first ever CTC video and having my eyes opened to the world of variants. Like so many people with their first CTC vid, I was so confused, barely following, but along for the ride. Now I'm actually attempting and succeeding at these sudokus. What a journey and what a channel! So many precious experience of discovery!
nearly 3 years after this was uploaded and it first showed up in my recommendations, it was recommended to me again. Only now I'm an avid cracking the cryptic watcher and it's all thanks to this video. wow time sure does fly.
Perfect feeling! Me at 3 AM here. Never did a sudoku in my life because I never knew how. And this guy does it like it is a magical thing. Crazy stuff.
@@aby1061 basically they added math to sudoku. No matter which way you turn the magic square it will add up to 15. Then they also added a bit of chess into the equation so it makes it easier to discern the location of certain numbers based off a chess knight.
This is the first "Cracking the Cryptic" video I ever came across, and I wanted to share that I finally solved it today. :) That's not to say I was working on it constantly; I just came back to it a few times over the months, but kept making mistakes, but today was when I finally solved it on my own, so I'm pretty pleased about that. :)
@@somestranger0283 the basic rules are: you need one of each of the numbers 1-9 in every row, column, and 3x3 box. And since there’s 9 cells in each, that means there can’t be repeats. Any extra rules are specific to the puzzle and are explained at the beginning of the video
I recommend you check out Ephermal Rift, he does a shit ton of good ASMR videos, and he even played Minecraft, and made a sacntuary, just type in youtube "Minecraft Sanctuary"
It's interesting how the sum of 15 in the magic square extends to every concentric ring centered on the 5. For example: top left (8) + center (5) + bottom right (2) = 15; bottom left (1) + center (5) + top right (9) = 15. There is a sort of radial symmetry with the sums where opposite points of each concentric ring satisfies the equation x + y = 10 (or x + y + 5 = 15 if we include the center square). This one may be my favorite yet.
Dude, this guy just seems so happy about the little things in life. The way he chuckles when he sees how cleverly the puzzle was made is so wholesome. Be like this guy. Enjoy the little things.
Dude, when he investigated the 2s to find out that magical link that plots everything nicely back to the start of his investigation, i nearly jump from my chair. This rewarding feeling is something that's been missing from my math class my entire school life. It gave me a new appreciation for Sudoku
I came to watch this after the mention in Aad's 80th birthday video, and two things: one, what an elegant puzzle this is and I understand how it's got so many hooked to sudokus, and two, Simon your "crowd work" has improved astronomically through the years. 😄
And I didn't expect to spend the next two and a half hours doing it myself and nudging the video forwards when I got stuck. Not sure if I should be proud of that or not, it took a long time
No idea how this ended up on my recommendations, i don't even like sudoku but i watched the entire video and am now looking for online sudoku puzzles. Amazing to watch! :D
Three by three Magic Squares have three rules. If you know them then you can solve any Magic Square of this size. 1) All rows, columns , and long diagonals must come to a sum of same number (generally a number divisible by three [3]). 2) The center number will always be 1/3 of the key number of the puzzle. 3) Corner numbers will always be 1/2 the total of the opposing short (two square) diagonal. The rules remain the same for squares that have decimal values (.23), or negative numbers in the squares (-42).
@@rrryn I had to learn those rules in High School (1970's) The books we used were obviously from another era of math classes (1950's?). If I had a way to send you diagrams it would probably make a lot more sense. I became so engrossed in Magic Squares I began doing them in decimal forms (.33 etc).
I was following along decently, then suddenly he pieced everything together, it sped up and I could no longer catch up. I totally felt like Watson at that point
There was a point when he knew the 4 was in the top right quadrant for the diagonal and not in the bottom left corner and I still don't know how he got that.
I used to do sudokus for a break from studying during medschool. I gave one of the hardest ones to my buddy, and he solve it in under 2 minutes. Writing them in from left to right top to bottom. I had always known he had the most impressive memory of anyone I have ever met. But in that moment I felt chills.
This is my favorite puzzle so far that I’ve seen. It’s not ridiculously difficult, the rules are easy to understand and the symmetry makes it beautiful. Hats off to the creator! 🎩 🙋♂️
The other day I wrote a sudoku solver in 10mins. I've been thinking I could probably add these extra constraints and then find one of the solutions I like then randomly reduce the number of starting digits untill there's more than 1 unique solution. Then I use the last unique solution.
I had homework aswell, but I chose to do the homework first and then watch this beautiful video with Bob Ross of Puzzles. Don't do youtube first kids, do homework! As a twist of don't do drug kids! XD
At first this seemed an impossible sudoku, but adding those magic square, diagonal and knight move made it interesting, but not very hard to solve. I like more of these twisted ones than originals with hard difficulty (*****). In those you need to plan few moves ahead and if you make a mistake you most likely find it only in last moves. My mom wasn't very smart and was poor in math, but solved sudokus really fast. She even didn't know how and couldn't tell others how to solve sudoku. Some excel in other fields of life than others and everyone have their skills which they master.
knight and diagonal move makes this solvable else it is impossible to solve. magic cube isnt hard to solve, its an easy algorithm, just need a restrain ( the 2 and 384 line made it a one way solve ) but it is still very impressive to solve. it seems like a giant unclimable mountain at first.
I have recently been teaching my partner Sudoku, she was diagnosed recently with MS, and we felt the process of problem-solving and connecting would help. Doing so had rekindled my own enjoyment, having not actively played for myself for at least eight years. This was my first challenge puzzle; after the five was placed, I felt I needed to see through alone, happy to have completed it in just over an hour. Looking forward to the day my partner and I can do these together.

This was the first CTC video I watched during the summer of 2020. I stumbled upon it simply because it had shown up as a recommended video despite having never watched a sudoku video before. I clicked it, I regret nothing.

It's really fascinating how the knights restriction actually makes narrowing things down easier.
Yes, restrictions are very helpful in this game.
Honestly a very fun variation on the game, I enjoyed it much more than the solving strategies I typically use for sudoku.
I play it everyday and now after learning this knight move, it's going to be easier.
Lalit Singh Fauzdar the knight move isn’t applicable to all sudoku, nor is the magic square. Both are additional rules for this particular puzzle
I love doing killer sudokus for this exact reason
The fact that the diagonals and knight’s move “restrictions” practically made this solvable is amazing to me.
Exactly. At first I was very skeptical when just seeing the board with 4 numbers, but those additionnal restrictions are actually huge clues and tremendiously help in solving it. Not saying it's easy, I'm no Sudoku expert (I don't really like them).
His software is pretty nice though! Taking notes like this in real life is more... messy haha.
Why? It just gives you more ways to eliminate numbers and figure out the correct ones
SuperUghe exactly. At first glance it just sounds like the “restrictions” would make it harder, when in reality they enable you to solve the puzzle.
Thats one of my favorite principles of game design, you cant always mark the end of the level with a reward, you can spice it up by showing the player where NOT to go
(I know it sounds stupid, but once you have it in your mind you realize how many levels could be upgraded with that phylosophy)
In fact, the three added restrictions (diagonals, knight's move, and magic square) made this sudoku much easier to solve than most regular ones. There wasn't even a single mention of any type of "fish."
My mind isn't wired to understand this at all, but it's so lovely to watch someone good at what they do, working away with such joy
This guy should have written the finale to game of thrones

@@aby1061 I though is my problem
@@aby1061 basically they added math to sudoku. No matter which way you turn the magic square it will add up to 15. Then they also added a bit of chess into the equation so it makes it easier to discern the location of certain numbers based off a chess knight.

It's interesting how the sum of 15 in the magic square extends to every concentric ring centered on the 5. For example: top left (8) + center (5) + bottom right (2) = 15; bottom left (1) + center (5) + top right (9) = 15. There is a sort of radial symmetry with the sums where opposite points of each concentric ring satisfies the equation x + y = 10 (or x + y + 5 = 15 if we include the center square). This one may be my favorite yet.

Three by three Magic Squares have three rules. If you know them then you can solve any Magic Square of this size.
1) All rows, columns , and long diagonals must come to a sum of same number (generally a number divisible by three [3]).
2) The center number will always be 1/3 of the key number of the puzzle.
3) Corner numbers will always be 1/2 the total of the opposing short (two square) diagonal.
The rules remain the same for squares that have decimal values (.23), or negative numbers in the squares (-42).
@Peter Kelly that confused me more.
@@rrryn I had to learn those rules in High School (1970's) The books we used were obviously from another era of math classes (1950's?). If I had a way to send you diagrams it would probably make a lot more sense. I became so engrossed in Magic Squares I began doing them in decimal forms (.33 etc).
I like the fact that the sudoku as a whole also is a magic square, with all columns, rows and the two diagonals adding up to 45
More like a magic square is kind of like a sudoku in miniature.
@@Nevir202 I guess, but in a normal sudoku the diagonals don't have to add up to 45, but in this sudoku it is one of the rules.
Yeah it’s only that way because of the diagonal rule
Maybe call it a semi-magic square.. a couple of the digits have been used more than once..
Not really, because a magic square only contains one of each digit.
never been so confused yet satisfied in my life

I was following along decently, then suddenly he pieced everything together, it sped up and I could no longer catch up. I totally felt like Watson at that point
IKRRRR
I felt like Watson from the start, not gonna lie
opposite for me, i had to really think at first with the magic square math but at the end it was all quick and easy stuff
There was a point when he knew the 4 was in the top right quadrant for the diagonal and not in the bottom left corner and I still don't know how he got that.
There was a point when he sped up and I thought, 'this ain't slowing down from this point, he's well and truly left me behind'
I used to do sudokus for a break from studying during medschool. I gave one of the hardest ones to my buddy, and he solve it in under 2 minutes. Writing them in from left to right top to bottom. I had always known he had the most impressive memory of anyone I have ever met. But in that moment I felt chills.

🙋♂️
What I wanna know is how someone _composes_ a problem like this!
Probably using brute force search with some heuristics to shorten the time need
The other day I wrote a sudoku solver in 10mins. I've been thinking I could probably add these extra constraints and then find one of the solutions I like then randomly reduce the number of starting digits untill there's more than 1 unique solution. Then I use the last unique solution.
I feel like the first step must be writing out the puzzle to completion and then gradually removing numbers so you can still solve it.
That’s soo true i had an Epiphany like half way through

That's actually a very interesting puzzle. The knight's move constraint is a nice twist on the traditional rules
At first this seemed an impossible sudoku, but adding those magic square, diagonal and knight move made it interesting, but not very hard to solve. I like more of these twisted ones than originals with hard difficulty (*****). In those you need to plan few moves ahead and if you make a mistake you most likely find it only in last moves. My mom wasn't very smart and was poor in math, but solved sudokus really fast. She even didn't know how and couldn't tell others how to solve sudoku. Some excel in other fields of life than others and everyone have their skills which they master.
knight and diagonal move makes this solvable else it is impossible to solve. magic cube isnt hard to solve, its an easy algorithm, just need a restrain ( the 2 and 384 line made it a one way solve ) but it is still very impressive to solve. it seems like a giant unclimable mountain at first.
yes
only way to solve it
Knights move makes it doable but then eventually makes it easy to solve once you've reached a certain point
I have recently been teaching my partner Sudoku, she was diagnosed recently with MS, and we felt the process of problem-solving and connecting would help.
Doing so had rekindled my own enjoyment, having not actively played for myself for at least eight years.
This was my first challenge puzzle; after the five was placed, I felt I needed to see through alone, happy to have completed it in just over an hour.
Looking forward to the day my partner and I can do these together.
