@@XiaoMingXing adding extra constraints should be nothing for a well-designed algorithm. However, if the base Sudoku algorithm is poorly structured and takes too many shortcuts... bodging the extra constraints in could be a problem.
It's quite interesting how these knights move puzzles tend to end up rotationally symmetric. If you rotate the puzzle 180 deg and overlay it with itself, all cells sum to 10 (in other words, when reflected through the center point, all 1s land on 9s, 2s on 8s, 3s on 7s, 4s on 6s, and 5s land on themselves).
Evan James 1:40 AM for me. I honestly thought the sudoku puzzles I did were pretty hard. Seeing 4 numbers tore me a new one but either way, great channel tbh. Never thought there’d be a sudoku channel.
At first when you were going over the constraints I was initially thinking "this is impossible" but they actually help you narrow things down, especially the knight's move constraint!
First 5 minutes of this video: How does this (a UA-cam channel with someone solving sudoku puzzles) exist? By end of video: of course this exists. How did I ever doubt it?
When I was 5 min into the video I spotted the viewed count (2,23 million) and it had only been on YT for 10 days and was realy shocked that anyone could get over 10 000 views doing sudoku, but damn was this a good video
Did I just watch a man solve a sudoku puzzle for 25 minutes with no background music or personal interest in sudoku? Yes, yes I did. Was I thoroughly engrossed the entire time? Yes, yes I was.
its kinda late at night, im tired, i do have to go to bed since 2 hours cause i really shoud rest, but i just watched this video and totally can agree with your comment XD (I should go to bed now)
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.
Here is the funny thing about this. This was the first video I ever watched on this channel. I didn't really even know about regular sudoku and never knew about these variants. I am also a fairly dim bulb when it comes to solving puzzles. This was so out of my league that I couldn't even understand it let alone try to get one number into the grid. But I have been an avid watcher and have been attempting to solve these puzzles every day since this. I decided to come back and try to solve this one just to see if I could do it without Simon's help. I did this puzzle in 17:04 and I was watching a basketball game that was distracting me on the side. This just shows what incredible teachers Mark and Simon are. I can solve about a third of the puzzles on here now, and with some slight miniscule help, can solve more than half.
I guess the views are a sign that there are still people with an attention span of over 30 seconds. I was sure that something like sudoku, which requires quite a lot of intellectual effort will not get more than 300 thousand views.
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.

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."

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. ^_^
Man: solves whole sudoku and shows little to no excitement Me: *figures out a number before him and is excited like a kid hearing the ice cream truck drive by*
especially near the end. there was so many possible ways to end it, I just took advantage of him pausing for 2sec to see one he didn't. meanwhile I would've spent 10 hours on the first 10 min of the video.
I figured out the top left square's 5 way before he did, and I know next to nothing about sudokus. I'm sitting here silently cheering in the dead of night. EDIT: I mean the top left 3x3 grid's 5.
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
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.
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"
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
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
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.
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!
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 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 would have never seen myself watching 25 minutes of a guy solving a sudoku puzzle, but the beauty of that puzzle combined with your commentary made it truly enjoyable watching. Thank you!
The only guy that would impress me more talking about this sudoku would be the person who designed it. I mean, resolve it is one thing, but making it ??? That must be insane, I want to know how people can create such amazing things
The average programmer can code a basic backtracking algorithm in any language that counts how many solutions there are for a given grid in a decent time. If you code a basic user interface you can fill the grid manually until you find one with exactly one solution. And it's easy to add constraints, it's just a few more lines of code. A more expert programmer can use a more advanced algorithm like Algorithm X with Dancing Links with a fast language like C or C++ and get an even faster solver capable of solving thousands of grids in less than a second.
Their puzzels are all hand made right up corner u can see the setter. Computers sure can make basic sodoku how ever with extra rules with a unique solution much harder and less fun
@@pierreardouin6441 these puzzles have to be handmade us to the necessity of them being unique, an algorithm can help with the creation but can’t really create the entire thing.
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.
That’s the most beautiful part about it imo. You can see his full reasoning and how he comes to find solutions, I don’t think I’d reach that level of sharpness any time soon 😂
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. 😄
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
The cure for that is trying to solve the puzzles and then watch Simon or Mark devestate the puzzle. and say sorry if they take more than 30 minutes to solve (and explain) the puzzle you never even found the breakin for.

"Oh that's easy so this must be __ and this has to be __"

I'm trying to solve it right now! The timer is on two hours, and I'm at 14:20 of this video....
It took my 20 minutes of abusing the check system to do it
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. ^_^
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
"Oh and we've done all the twos all of a sudden. Wow. Wow, how elegant is that?" Very elegant my friend, very elegant indeed.

Man: solves whole sudoku and shows little to no excitement
Me: *figures out a number before him and is excited like a kid hearing the ice cream truck drive by*
especially near the end. there was so many possible ways to end it, I just took advantage of him pausing for 2sec to see one he didn't. meanwhile I would've spent 10 hours on the first 10 min of the video.
I was only moderately excited to place the 4 in the bottom row 2 minutes before him at 22:00. It only shows how many ways there are to solve a puzzle.
Michael Robertson i was talking about that 4 too haha 😁
I figured out the top left square's 5 way before he did, and I know next to nothing about sudokus. I'm sitting here silently cheering in the dead of night.

The hardest part was the magic square and completing another line in next square. The diagonal and knight's move make the rest of the sudoku easy.

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.

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 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.

I'm watching this at 6 AM rn
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
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. :)
25 minutes of me silently saying “ahh yes of coarse” to myself even though I had no idea of what was happening
i dont even know how sudoku works, but i still watched the entire thing, i dont know why
@@somestranger0283 start from basic ones, they're a really great puzzle
@@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
Course*
@@tacocatt6808 no he meant coarse, sudoku is a rough game
"Wow how elegant is that..."
I'm actually speachless
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
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!

Dear UA-cam algorithm:
Thank you, nailed it this time.
Я тоже в шоке!
I love how far this has come in two years. 4 given digits and 25 minutes is a GAS puzzle these days 😂
The comments seem to be filled with people like me: really no clue whats going on, but really enjoying it anyway
How do you get so many like xD
@@jearandmangubat9414 Because the comment section is filled with people like me :D
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.
I wasn't expecting myself to watch sudoku tonight. But I'm not complaining that was fun.
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!

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
@@oblivion_2852 Could this technic be used to make a good compression tool
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'
So fun coming back to some of these a year later. "Only 4 digits?" Oh my poor summer child. You have no idea what's coming.
I'd love to see one of these done with eye-tracking software used to show how he scans the grid.
hopkirk87 That would be a really interesting video. Insight into how the mind works...

“And the bookshelf goes right there for obvious reasons.”

Plus nobody wants to help him with his night move.
*enters numbers here and there*
"suddenly we've done all the 2's"
Me: *enters 1 number*
"suddenly we've got no more moves"
The only guy that would impress me more talking about this sudoku would be the person who designed it. I mean, resolve it is one thing, but making it ??? That must be insane, I want to know how people can create such amazing things
Surely computer algorithms these days?
Making a puzzle is much harder than solving it.
The average programmer can code a basic backtracking algorithm in any language that counts how many solutions there are for a given grid in a decent time. If you code a basic user interface you can fill the grid manually until you find one with exactly one solution. And it's easy to add constraints, it's just a few more lines of code. A more expert programmer can use a more advanced algorithm like Algorithm X with Dancing Links with a fast language like C or C++ and get an even faster solver capable of solving thousands of grids in less than a second.
Their puzzels are all hand made right up corner u can see the setter. Computers sure can make basic sodoku how ever with extra rules with a unique solution much harder and less fun
@@pierreardouin6441 these puzzles have to be handmade us to the necessity of them being unique, an algorithm can help with the creation but can’t really create the entire thing.
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.
i love that he shared with us his complete train of thought! this is golden!
That’s the most beautiful part about it imo. You can see his full reasoning and how he comes to find solutions, I don’t think I’d reach that level of sharpness any time soon 😂
This puzzle is like when were kids trying to create new rules and turns out that you’d go back to the old rules
I love how whenever he finds something he calls it powerful

Every times he says "Wow"
“25 minutes of a guy playing sudoku? Who would watch that?” 25 minutes later “oh”.
