After the week I've had working on this thing, it's delightful to be able to relax at watch it solved. :) And yes, it absolutely was a Cream reference... the first named version of this exploration (way back at 26 caged cells) was called Derek and the Dominos (being entirely two-cell cages), and I took to naming the whole progression after Clapton bands and songs.

I'm still stuck finding a cell, trying out the options and seeing what happens next. I recently did one of the new domino puzzles in the cracking the cryptic app and that had digits that you knew propagated around the grid so that "this can't be 3, because either it sees 3 in the row or the column"
@@scottmsul This was the trickiest logic step for me as well. I looked for a *bent triple,* I did not find it, and eventually managed to rule *6* out of *r3c4* by just testing the effect of *r3c4 = 6.* I do not realy know how I was able to identify that cell as a weak spot, but I studied other *bi-value cells* for several minutes before spotting that one.
This is a masterpiece. The brilliance of it is that it looks nearly impossible to solve at the outset, yet no advanced techniques are involved in the solution. It’s actually very approachable.
@@alainculos9294 I've forgotten everything I ever knew about classic Sudoku and was never good at bent triples to begin with, but lucked into finding a 36 cell that was always a 3 after inspecting the grid for a while. Chain wasn't ridiculously long, I'll take it.
After having had the great fortune to be one of the first people to test this one over on the Discord when it appeared yesterday, I've been saying that everyone needs to try this "clearly impossible construction." I have never been less surprised to a puzzle get on to the channel this quickly. It's just such an astounding construction. And, Simon's reaction to seeing the grid is everything I could have hoped it would be. Even having been following the quest for minimal killers, I couldn't quite believe it myself before I solved it. Philip is truly a mad genius.
The "Miracle Sudoku" by Mitchell Lee was my introduction to this wonderful channel, and this video showcases the same qualities that have me hooked ever since: Simon's utter joy at the unfolding beauty, and the way you seemingly effortlessly perform marvellous feats of logic AND explain them in an understandable and entertaining way. Thank you so much for sharing this with the world!
Ridiculous. Legit stunned. I have no idea how long it took me because I paused the timer to read the rules like six times, being like "that's it"?? But then I saw something in the grid and started typing and all of a sudden it was done and I was so engrossed I'd forgotten to start the timer! Absolutely genius. So flipping cool
I usually watch these as "backround noise" while I'm doing other things. But this one I was sitting with my hands on my headshaking it going "This is just insanity". This and the other miracle sudokus just completely blow my mind
I would love to see a video with a compilation of bloopers... The broken sudokus and pranks that you've been playing on each other because in a bunch of videos you say that the video won't air... Would love to see those that DON'T air... And ofc, the phone calls after the broken videos!
I watched Philip take the journey of finding/setting this puzzle on the discord and the payoff is so much more than anyone expected! Practically everyone thought the minimum cell coverage must be somewhere around the mid-20s, and the idea of finding anything close to 18 was laughable! I don't blame you for thinking you were trolled, because the fact that this puzzle exists is extraordinary on its own. But it also has such a great solve path? Definitely one for the Sudoku history books! And yes, the search goes on for a 17 cell coverage puzzle :)
Over 50,000 regular sudokus with only 17 cells have been found. Each can be converted to a killer sudoku with only 17 cells, by putting one cage round each number!
@@gilesbrennand7529 Well, not each one, because not all of them can be morphed to have the givens adjacent in such a way that a cage can be drawn. It's certainly an area to explore, though.
@@Rangsk I think GIles meant having the givens as one cell cages, so you basically transform regular givens into pseudo killer cages to get a killer with 17 cells coverage. And yes, I do expect that to have been a joke, because you can't really call that a killer sudoku then.
Killer Sudoku cages do so much more than just plain digits. My guess is you can go lower than 17. Maybe much lower? There's so much more logic they imply
@@guycomments This is simply untrue. Consider that there's a puzzle where only 16 cells are covered by killer cages and solves uniquely. Take that and fill the cages with given digits from that unique solution. Do you agree that given digits in every cell covered by cages is strictly more information than just having the cages? It must be, because the only thing the cages tell is is something about the value of the covered digits, and putting givens there tells you more. Given digits in all the cages will tell you that there can't be repeats, because they don't repeat, and it tells you the sum because you can add them up. In addition to that, it tells you exactly what combination is used for the sum and the order that they go in. This is significantly more information. So, now you can remove the cages and not lose any information, and you have a 16 given classic sudoku that solves uniquely. We know this is impossible, so the lower bound for cage cell coverage to solve uniquely is 17. Since this video was released, on the Discord we've proved that no known 17 given puzzle can solve uniquely when replaced with killer cages, so it's not a proof, but we're pretty convinced that 18 is in fact the minimum.
I've been watching the channel for a very long time and I think this easily becomes one of the top 5 mind-blowing puzzles I have seen. If we had a category for the best approachable puzzle for the average solver it would be hard not to make this #1.
I admit I don't watch the videos where people explain how they set their Sudokus but in this case i WANT to know how Mr Newman came up with this. The way the 89 pairs spread around the grid was like watching a flower bloom. What a masterpiece!
I got to the point at the end with everything penciled in, but could not spot the bent triple. I ended up just testing out the 3 in box 8 to see if it would break, and when it didn't break, I realized the puzzle was just solved at that point. I have some work to do learning to spot those bent triples. Still a very fun puzzle to play.
Eurgh, those Y-wings/bent triples are the bane of my sudoku existence. I cannot for the life of me spot those things! Anyway, amazing puzzle and just a joy to watch. Well done!
Ive been watching CTC for over a year. I found it really calming early in the pandemic when I was bored and stressed all the time. This was the first puzzle that i was able to solve without the video! Beautiful logic to it!
That bent triple at the end made me think I had broken the puzzle somehow as I couldn't spot it at all... Beautiful solve, and thanks to Simon for pointing out the solution!
Oh, wow! Something I love - I solved this in the opposite order, tracing down where 12s could go before I attacked the 89s. And it's no less beautiful through that route! (Maybe even more so - you get that startled "wait, did I just constrain both colors almost completely on the grid?!" feeling _twice_) Philip, you are a master. This was great!
I can't stop crying at how beautiful this solve was. Just so elegant. I feel like this is the point in which sudokus act more as poetry than puzzles. Bravo Simon on another flawless victory
Simon: ".. this is futile", "I'm not going to say solvable, because it simply isn't " ... then proceeds to solve the puzzle! Absolutely incredible solve and an incredible puzzle. A joy to watch!
Sublime puzzle! Despite having such low info, it has a very natural solve path, which makes it very fun and not too hard. It has become one of my favourites featured on this channel.
It took me close to 30 minutes to get to the idea of coloring 89s. For Simon it took like 3 seconds. When I watched the video, I could not believe how fast he got the right idea and was on the right path. Truly remarkable sudoku.
As a Killer Sudoku fan, I am quite used to starting off with no digits. But with such a paucity of cages? WOW -- Kudos to both the setter and the solver, what a joy!
16:14 for me. What an amazing puzzle, so few clues and the way they all work together. I would love to watch a ‘How I set sudoku’ video on this one in particular. Even if it’s not one of the most difficult ones we’ve seen lately, it’s one of the most impressive imo.
I really liked this puzzle. It took a hair less than an hour, but calling this a "white" room is a real misnomer. My puzzle looks like a rainbow exploded onto it.
First time I'm trying to solve a sudoku from this channel, I now totally understand the joy of cracking them. When pieces start falling into place, it's so elegant! Thanks for sharing these.
I’m so happy. I’ve not completed a single puzzle on this channel but this is by far the closest I’ve come. I got as far as Simon did before he found the bent triple. Really good to watch after I got stuck. Well done Simon and thank you
This is one of the rare puzzles I could actually complete. Took me many hours, and a few redos, but I finally got it. It is crazy how any information can be deduced, let alone the entire grid. But it somehow has a way even I can see.
Sudoku techniques must be sinking into my brain via osmosis or something, because near the end I was thinking "I bet he needs to look for a bent triple here" without knowing enough about them to spot where it was myself!
I got stuck and couldn't find the bent triple! It's pretty funny that in the end the "hardest" part of this puzzle was just solving a classic sudoku. :D
The sheer abject horror and disjoy that Simon felt when he first glanced at the Sudoku, compared to the love for the puzzle when he solved it, that is truly the best part about watching Simon's solves. The sheer disbelief contra the bafflement of it being solvable. Truly what makes a masterpiece.
This really was an incredible puzzle, and it was neat to see how the logic flowed once you got started. I'm glad to see that Simon's solve of the puzzle went much more smoothly than mine because I had to restart this puzzle about 5 times because of careless mistakes on my part. But I guess that just made solving it correctly all the more satisfying. I even spotted the Y-wing near the end, and I'm usually bad at finding those.
What a sublime puzzle! Ive been watching for well over a year now and this is easily top 3. I did the logic on 1s and 2s first. The virtual x-wing works just as well without any cells being populated by high numbers. When watching Simon's solve I thought I had missed a lot easier path, but finally he had to find it too. It's interesting that you have to come from both sides to narrow things down. And the order in which you proceed is irrelevant. Great puzzle and great solve! Thanks to Philipp and Simon.

I am always delighted when you explain bent triples. Very nice puzzle, solved in an impressive way!!! Thx!
After watching the video for 10 min I decided to give this sudoku a try and with that help of colouring I was able to solve the puzzle in less than an hour.
I really enjoyed solving this one! I found it easy, then hard, then easy, then hard.. Quite a roller coster of emotions! Now let's learn by watching Simon
I'm by no means good at sudoku, but I managed to solve it after trying for over an hour. It's a really beautiful puzzle. The only reason it took me that long is that I'm so slow to spot the logic, and that I make mistakes pretty often. It came together very nicely whenever I did spot the next step. Lots of parity logic which has to be my favourite.
40:54, didn't see the bent triple, did it with bifurcation except that I didn't prove the negative, just got lucky with the puzzle solving. I enjoyed the break in not being the 5 and 6 cages, which is what I assumed.
It's funny--this is the first puzzle on this channel I've been able to solve completely on my own, and from the get-go I was really intrigued by the way the cages interact. I started off the way Simon did with the high-value cages, which yields all the eights and nines, but then I was drawn to the low-value cages. The way they interact with each other, competing for the low-value digits, was how I eventually got enough digits in to solve the rest of the puzzle.
That was AMAZING! This is no doubt the BEST sudoku I've ever solved!!! And I don't even like killer Sudokus! What a ride. What a joy. It wasn't even that hard, but it also wasn't easy! This Philip, is a masterpiece! Thank you for finding this gem and sharing it with us. My wife is going to hate me for trying to explain the adventure I just did for the rest of the night! 😜
This was just *amazing*, really. And I'm wrinting this before even watching the video. Took me a while to realize I should do something with 8s and 9s (instead of a complicated relation between all the 5,6 and 7 cages), and I couldn't believe how everything worked from there. Absolutely brilliant, bravo!
Actually, at this point in the puzzle we know that there is no anti-knight constraint, because two of the purples are a knight move away from each other.
Absolutely beautiful puzzle. It looked utterly impossible at first but... it wasn't actually that hard because it flowed so well, so elegantly. It still took me an hour but about 20 minutes of that was disambiguating 3456s with classic sudoku that I'm terrible at.
Never got so excited for a puzzle. Amazing work Simon, I love how you make us enjoy and Feel your emotions. Also greetings to the creator of this minimalistic masterpiece
I have watched the first part of the video 3 times already! It's just so funny seeing you thinking that this puzzle must be (IS!) wrong and is unsolvable, but then for some miracle it actually starts to work! :D
loved that puzzle, was shouting at the beginning to colour it, simon colours all the purples and greens, i thought it was amazing how he was in awe the whole video
Please, you simply must prostrate yourself before Mr. Newman and plead with him for a video on how he set this. It's magnificent. To see how he slowly shaved off digits to create nearly the most minimal and elegant killer sudoku imaginable would be fascinating.
34:05 ... took me longer than other 'discovery' puzzles, and my solve was almost certainly less elegant than what the video shows, but no matter: this is an INCREDIBLE Sudoku! Nice puzzle!
After the week I've had working on this thing, it's delightful to be able to relax at watch it solved. :)

I wonder if this will start a race to find a unique 7 cage solution
The big thing you've done is that Simon now owes us a Clapton intro (2:38)
this was without a doubt one of the best solves ive seen on here. bravo. bravo.

It's interesting that you have to come from both sides to narrow things down. And the order in which you proceed is irrelevant.
Great puzzle and great solve! Thanks to Philipp and Simon.
I am always delighted when you explain bent triples. Very nice puzzle, solved in an impressive way!!! Thx!
After watching the video for 10 min I decided to give this sudoku a try and with that help of colouring I was able to solve the puzzle in less than an hour.
this has become my favourite video on the internet
I really enjoyed solving this one! I found it easy, then hard, then easy, then hard.. Quite a roller coster of emotions!
Now let's learn by watching Simon
I'm by no means good at sudoku, but I managed to solve it after trying for over an hour. It's a really beautiful puzzle. The only reason it took me that long is that I'm so slow to spot the logic, and that I make mistakes pretty often. It came together very nicely whenever I did spot the next step. Lots of parity logic which has to be my favourite.
An absolutely outrageous puzzle; absurd, in fact. Fantastic work by Philip Newman. Can we have a setter's video for this masterpiece?
I enjoyed this one so much that I had to go back and watch it again!! I love Simin’s reaction throughout the whole puzzle!!
I was wondering what purpose the colors served. This opened up a new strategy for me on the expert level puzzles. Thank you!
40:54, didn't see the bent triple, did it with bifurcation except that I didn't prove the negative, just got lucky with the puzzle solving.
I enjoyed the break in not being the 5 and 6 cages, which is what I assumed.
It's funny--this is the first puzzle on this channel I've been able to solve completely on my own, and from the get-go I was really intrigued by the way the cages interact. I started off the way Simon did with the high-value cages, which yields all the eights and nines, but then I was drawn to the low-value cages. The way they interact with each other, competing for the low-value digits, was how I eventually got enough digits in to solve the rest of the puzzle.
That was AMAZING! This is no doubt the BEST sudoku I've ever solved!!! And I don't even like killer Sudokus! What a ride. What a joy. It wasn't even that hard, but it also wasn't easy! This Philip, is a masterpiece! Thank you for finding this gem and sharing it with us. My wife is going to hate me for trying to explain the adventure I just did for the rest of the night! 😜
Love to see that simple-ruled puzzles can be amazing.
Totally!
Beautiful puzzle, and surprisingly approachable. Took me 39 minutes.
This was just *amazing*, really. And I'm wrinting this before even watching the video. Took me a while to realize I should do something with 8s and 9s (instead of a complicated relation between all the 5,6 and 7 cages), and I couldn't believe how everything worked from there. Absolutely brilliant, bravo!
Love the reaction to it. Wanna experience a similar surprise someday…
Just unbelievable brilliance by both Phillip and Simon! Such a compelling video!
Best movie I watched all week!!!
I solved it in 45 minutes, and I'm not sure how. It was like the setter was pushing me forward the entire time towards the solution.
"I haven't needed a knight's move yet" - Is this the sudoku equivalent of PTSD flashbacks?
Actually, at this point in the puzzle we know that there is no anti-knight constraint, because two of the purples are a knight move away from each other.
"and these bent triples... are they in the room with us now?"
Absolutely beautiful puzzle. It looked utterly impossible at first but... it wasn't actually that hard because it flowed so well, so elegantly.
It still took me an hour but about 20 minutes of that was disambiguating 3456s with classic sudoku that I'm terrible at.
Goes from the puzzle being unsolvable, to solving it in under a half hour. Nicely done.
Brilliant puzzle, brilliant solving
Being able to spot the same bent triple/Y-wing as Simon (albeit much slower) is such a rush.
Never got so excited for a puzzle. Amazing work Simon, I love how you make us enjoy and Feel your emotions.
Also greetings to the creator of this minimalistic masterpiece
Mind blown!! by a mind blowing puzzle.
I have watched the first part of the video 3 times already! It's just so funny seeing you thinking that this puzzle must be (IS!) wrong and is unsolvable, but then for some miracle it actually starts to work! :D
Just started watching this, how is this ever going to be uniquely solvable. This must be a miracle indeed.
Edit: WOW ♥️
I do believe this is my favorite sudoku
loved that puzzle, was shouting at the beginning to colour it, simon colours all the purples and greens, i thought it was amazing how he was in awe the whole video
Magnificent! That's the best one in last 2 years as for me
I was starting to struggle and then, like Simon, I thought "let's break out the colours". Beautiful puzzle and really not that tricky.
Thank you
I wish I'd done coloring for the 89s, but instead gave up too early, figuring it was a crazy mind bender.
Please, you simply must prostrate yourself before Mr. Newman and plead with him for a video on how he set this. It's magnificent. To see how he slowly shaved off digits to create nearly the most minimal and elegant killer sudoku imaginable would be fascinating.
34:05 ... took me longer than other 'discovery' puzzles, and my solve was almost certainly less elegant than what the video shows, but no matter: this is an INCREDIBLE Sudoku!
Nice puzzle!
