One Of The Cleverest Puzzles EVER

[@Knickolas]

Hi everyone, Knickolas here! And wow, what an impressive solve from Simon. His ability to find and articulate his way through such difficult logic will never cease to amaze me! Thank you so much for the feature and for your incredibly kind words :)

[@charliemcadams07]

Knickolas, Thank you so much for creating this masterpiece. For what its worth I think this is the best puzzle I have ever seen. Absolutely staggering.

[@kathyjohnson2043]

I know it can take a huge amount of work to create a puzzle. Thank you for sharing this with us all.

[@JaymanOttawa]

You have created a truly brilliant puzzle Knickolas! You should be very proud of your efforts... :)

[@likara6667]

This is an amazing puzzle, and I'm with Simon; how the heck did you create this? The logic and brainpower required to create this seems superhuman to me!

[@AllenBaranov]

Beautiful puzzle. Well done.

[@mattinm]

49:10 - Simon: “Why couldn’t that be 3 (in blue)? No reason at all…” Normal sudoku: “Am I a joke to you!?”

[@birkheadc]

I have never screamed so loud at a KZbin video

[@PhaythGaming]

I came to the comments for this alone. I’ve never felt so much rage.

[@jimi02468]

This made me mad

[@marcelopicheth6111]

Every time that there is an additional rule to "normal sudoku applies", Simon forgets entirely about normal sudoku rules... hahahahaha

[@Soccerjakob]

This was the first time I had the inevitable "yelling at Simon" moment... Normally If I see something before him I'm just happy to have spotted it, but this one got me

[@BenCragg1]

At around 50:00 there is a seemingly erroneous claim regarding the bottom left region not being able to be 9 cells; Simon's experiment includes a cell it doesn't need to, and would theoretically allow exactly one 9 cell region. Luckily for Simon, this region would require exactly 3 cells on the line, which would clash with the 3 in red (R3C1) - which he hasn't placed yet, but is easily placed by Sudoku. So the logic can proceed as normal from this point :)

[@bennettgardiner8936]

Spotted the error, but not the resolution, nice one

[@bennettgardiner8936]

That's an absurdly intricate piece of logic to build into the solve if necessary to see, I share Simon's amazement with this one

[@davidbouldin3326]

Noticed this too and came to the comments to see if it had already been spotted. Thank you for saving me the explanation by explaining better than I could have anyway!

[@gerdkah6064]

but WHY?! why didnt Simon explore it further and just filled it in while saying 50:33 _"so i think .."_ - this makes me shouting and stampeding and all sorts of madness ^v^

[@BenCragg1]

@@bennettgardiner8936 I spotted it relatively easily - it did help that I already had the 3 that Simon missed when he decided to do Suduko briefly, but also decided not to use the digits he already had XD That said sometimes one just spots things :)

[@loqueestamal3465]

I love how Simon marks the outer edges of regions, lest they go a-meandering outside the grid.

[@boriserjavec6470]

LOL

[@blcmd]

I did the same. If nothing else, it just looks better.

[@th.nd.r]

@@blcmdi gotta agree!

[@1manApocalypse_CP]

To be fair there are puzzles that are bigger than 9x9 xD

[@SpydersByte]

it would look pretty weird with the inner lines boldened but not the outer one lol

[@thekilla1234]

1:45:13 I get much more invested in the longer videos than I do the shorter ones. If I see a video over 1 hour I am watching it all the way through every time because the length pretty much confirms that there will be some very wacky things happening and it's always very entertaining to see it unfold.

[@TrackpadProductions]

_"It took our testers over a _*_month_*_ to solve it - so this might be a longer video."_ Video length: 1:46:13 I don't think he really fully grasps how incredible this sentence is.

[@amerkayal]

Same here!

[@WilliamSurles]

I need to go to bed. But clicked this thinking "I'll just watch for a few min" Nope. 1:45 later... here I am at the end. And my eyes are wide at how freaking clever this puzzle is, and how brilliant Simon is to figure it out. He just knows what square to pick on to squeeze out that next bit of logic, like no other.

[@dennishebert2801]

It never ceases to amaze me that every time Simon solves a puzzle, I think to myself, "Well, I could have solved that," simply because he makes it look so easy and explains everything so delicately. Wonderful solve yet again!

[@humanbirdsong]

“Three of our testers failed, and the other took a month. Anyway, do have a go.”

[@th.nd.r]

UTTERLY UTTERLY INCREDIBLE. Needs to go in a future CTC book. One of the best in a while. I hope Knickolas gets another channel feature soon based on this. The length of this video was absolutely justified. It was difficult, yes, but there really wasn’t any moment where Simon spent a lot of time mulling over things, meaning two things: (1) Simon is brilliant, and (2) Knickolas was somehow able to pack over 90 minutes of pure condensed joy into one, regionless, digitless 9X9 grid with just a few circles and lines in it. Absolutely spectacular setting and solving. Favorite quotes from today’s video: - “That is a blue domino of blueliness.” - “Again, we cannot go a-meandering.”

[@tychoderkommentator2989]

I am always impressed how fast you notice the next region where you can have a breakthrough. Most of my time is searching for the next weak place, but you find them immediately and then only have to think about why that place is weak.

[@PhaythGaming]

Just letting you know that your rules link is almost always wrong!

[@jessienewman3879]

Rules isn't until 5:43

[@jakekapitz]

@@PhaythGaming Probably because Simon usually says the word "Rules" before launching into the announcements (in this case "I'll read you the rules in just a moment")... Presumably the bot is just listening for the first instance of the word "rules" for the timestamp.

[@PhaythGaming]

@@jakekapitz for sure, I assumed the same. Just letting them know in case they want to attempt to fix it. There are many potential solutions but I just thought to mention it as I know it’s a bot and when they first started doing these they responded quite often, so you know.

[@JBroMCMXCI]

Change your bot to select the last time he says "rules" before he says "let's get cracking"

[@jacobroberts5604]

Finished in 51:05, absolutely beautiful puzzle. It's a testament to how much I've learned watching this channel that I even finished at all, I couldn't have imagined solving this two years ago!

[@danielepicone1480]

What an amazing puzzle, I was hooked for the whole video of almost two hours and I was still craving for more. The solution path is just so elegant and the way Simon is methodical about his solve it also makes you see almost all the tricks together with him just by following his cursor.

[@pardox28]

Trust Simon to ask "where does the 3 go in row 3" & not see that he would already know it goes in r3c1 if he thought about sudoku ruling out the two blue cells in row 3. He must figure that out the most difficult way possible.

[@adamusher468]

Long time watcher, first time commenter. What a joy this solve was to watch! The best puzzles are like an adventure narrative and have you gripped like any of the best feature length films! Thank you Knickolas and Simon for the premium entertainment! I am in awe of you both!

[@Lucroq]

My favourite part of all these genius puzzles is Simon's genuine praise after solving one of these beauties. I think it's easy to overlook how tightly all the constraints have to work together to force the solution at the end. And Simon's clear explanations of his own thinking does illuminate some of the internal logic bit by bit. So whether you can see some parts way earlier, or you are just following along, it does paint a beautiful picture that necessarily leads to the complete whole at the end. I would really like to watch a video where one of the puzzle creators explains their process to get to a fully determined state with one of these masterpieces at the end.

[@abcde_5949]

49:09 But why couldn't this blue line segment have a three on it? No reason at all (except being literally surrounded by threes)

[@Astervista]

“Are these threes trying to tell me something?” 😂

[@moosesox]

There was a single cell gap on each side, and one of the 3s wasn't pointing at those cells at all. Only world-class scanning would have picked that up.

[@Posiadam.]

50:29 you’ve got really lucky here Simon! The orange region could theoretically go to the circle in R8C5 - the only thing that wasn’t taken to the account was that the new region in the bottom left would contain 3 segments of the line - exactly the same as the red region and therefore both circles in row 7 would contain 3… SICK!. The rest looks perfect, such a great puzzle!

[@glum_hippo]

This is indeed an astonishing puzzle! Normally I'd say "More please", but I'm not sure we'd be able to digest more such fantastic logic and sleuthery!

[@jonathanweber2893]

Surprised myself by actually spotting where to begin this by noting every region needed a circle and asking which ones could reach the top left. Simon pretty quickly left me behind him from there, but a credit to watching him solve so many puzzles that I was able to spot that at all!

[@kevinjschuster]

I did the same thing ... found that spot quickly, and just as quickly I got stuck and waited for Simon to catchup and pull me along.

[@mrmichaelhallett]

I love your enthusiasm. Its so contagious. I could not solve such a puzzle in my wildest dream.

[@chitraagarwal8259]

There's no way i could have even begun to solve this puzzle so instead I watched this video in about 4 hrs over two days in multiple installments... pausing each time to figure what the next steps could be and then like Simon just spending so much time thinking of HOW, JUST HOW could someone come up with such amazing logic. Knickolas definitely ranks really really high among very illustrious company of the out of the world puzzle creators who are the reason this channel continues to amaze and enthrall its regular followers. Awaiting the constructor video for this that absolutely must be made. Thanks so much as always to Simon and Mark for providing this platform so we get to see these genius creations, and for being our intellectual 'sherpas' guiding our thinking through logic we wouldn't have figured on our own.

[@Astervista]

Oh no it’s going to be another two hours beautiful puzzle I won’t be able to stop watching, isn’t it

[@LiquorStoreJon]

[@joethornton5321]

Spent well over two hours solving in several sittings and have rarely been so proud of a solve, having listened to Simon's introduction. Definitely one of the toughest puzzles I've managed, and what a beautiful creation it is. Many thanks to the setter for sharing it.

[@Pulsar77]

This one was absolutely brutal. After two hours of battle, I broke the puzzle, and I had to check with Simon where I had gone wrong. Turns out that I had accidentally placed two 8s into the same region... I'm very pleased that my region construction was right though. A few months ago I wouldn't have even attempted this, because chaos construction is so unforgiving. One wrong deduction and you might as well start from scratch (or cry yourself to sleep).

[@auntielaura5]

You’ve earned your lunch Simon! Fascinating puzzle! The really long videos are my favorites, because I know that the puzzle is so difficult I wouldn’t even attempt it. Yet, due to your brilliance, I will end the video understanding every bit of the logic. I don’t know if it makes me any smarter, but I definitely *feel* smarter. 😁❤️

The actual sudoku use of [number] in the beginning of this puzzle makes this just beyond beautiful.

[@no-feetmcgee5577]

I usually wait until the end, but this time I had to pause at 27:29 and "like" the video the moment Simon said "Blueliness". Sublime.

[@brianpronk9809]

What i find so amazing, it that even when he says a tester takes a month solving this puzzle, Simon manages to solve it in well under 2 hours ánd explains every step he takes. Legend.

[@chrishawkins963]

Simon didn't see what i think is the intended logic at 50:10 as this set-up is actually just barely doable if you give r6c2 to the bottom left region, but that makes r7c1 equal to r7c5, and thats the only possible setup to make r7c1 not orange.

[@clem8422]

Thanks for this comment, I noticed that possibility, but couldn't figure out why it wouldn't work! Btw, I think you wrote r5c2 in your explanation, instead of r6c2. Might be worth an edit :)

[@chrishawkins963]

@@clem8422 yeah you're right, thanks.

[@ericpraline1302]

Another mind-boggler. Was happy to make some deductions quite quickly but then as so often hit a wall and became more or less comatose before finally cracking on. I think the people who come up with puzzles like these are, in the nicest possible way, slightly mad - I'm very glad they are the way they are - but as Simon often remarks it is completely incomprehensible to me how they do it.

[@guilhermemonsores]

Incredible puzzle indeed! took me a couple hours actually to crack it but it was just so worth it. Even more rewarding when i come back to the video and watch Simon taking the same logical path to the solution (but in a much more elegant and quick way).

[@darrenbent7601]

I love your light-hearted approach with your commentary. I had a go at it, and I gave up, couldn't even get off of the starting block. I don't think that I had the power of Greyskull. And those threes, how you worked that out, just plain WOW!!!!!

No 3 in the corner, but there are absolutely 3's in thevspotlights. Fantastic puzzle to watch!

[@Tsevion.7]

An absolutely beautiful puzzle... and I'm overly pleased that I beat the video length, finishing in 98 minutes. I think one of the things I found most interesting is how even the difficulty curve is. It's not like some puzzles where the breakin requires whole new upside-down outside the box thinking. It just requires noticing certain things and applying good logic. And the puzzle proceeds just like that. Every next step is hard, but not insanely so. But the puzzle impressively keeps that difficulty right up to the end. Even once it's down to essentially an irregular sudoku, it's still a tough one, but never ridiculously so. So yeah... Some of the most impressive setting I've ever seen... Taking both Simon and I an hour and a half, and neither one of us ever really gets stuck... just an hour and a half of solid puzzle solving. A Masterpiece.

[@yant3303]

67:50 for me. What a beautiful puzzle with a nice flow all along. Thanks knickolas!

[@Trandhal]

For all the years I've watched CtC, this is the FIRST puzzle where I've been mentally ahead of Simon at all times. I don't know it that means that Simon was particularly slow today or if I've gotten massively smarter overnight. Both seem equally unlikely.

[@SirJefferE]

I'm always slightly ahead of Simon when I watch the videos, and massively behind him when I try to solve on my own. I suspect I'm lying to myself about how much his comments and train of thought help me "get ahead" of him.

[@nicfab1]

@@SirJefferE that's common with almost all instances of watching other people solve challenging problems.

Solved in 2h48m without using the video, my par time is usually double the video length, so pretty happy with that! Going back to Simon's solve afterwards shows there were loads of different ways to get digits in the sudoku section at the end. He spotted so many things that I didn't, but I muddled around them anyway.

[@clarematthews4051]

A 90 minute solve time? I'm not even trying it. I'm not even trying it. I watched the first few minutes of the solve. Everything Simon said I'd already worked out - the circles being in different regions. When he clicked on the top left square I stopped watching because my head had an "Ahhhhhh!" moment of realisation of which circles it couldn't go with. Solving it myself was lots of fun. Times of wondering "how the heck did that work out so beautifully?" interspersed. I agree, it was a very excellent puzzle and I'm very happy to have completed it, just in time for the Glum_Hippo email to arrive, six minutes ago as it turns out. But that'll have to wait for tomorrow. Finding regions has worn me out and being engrossed by it caused me to miss a bus.

[@Jesthers]

Solved this one all on my own! Very fun puzzle, kinda felt like two different puzzles: finding the regions then solving the sudoku lol Very fun, I highly recommend this one!

sometimes I think the "harder" puzzles are actually easier because they seem to force you to look for what is often only one place that gives under the logic; maybe they're considered harder because they generally take longer. regardless, a brilliant puzzle--thanks Knickolas. and as always Simon, you bring a great deal of joy

A question/request to you Simon: Could you possible a different colour for drawing lines and borders (it used to be some kind of sweater-green a while ago...)? It was easier to discern than black vs thin black vs even thinner black, especially when there is a lot going on. Nevertheless, you always help me to decompress from my job by getting me to thinking just for thinking's sake. Keep it up - you rock!

[@gregs2284]

The logic at 22:00 is *sick*. Imagine putting logic like that into a puzzle not in the actual grid but in the hypothetical grid that you're ruling out.

[@Tepalus]

50:20 Big mistake! The circle HAS enough space for it to not be orange (taking the topright cell of it and connecting red to the top of the "circle domino". I just skiped to the end and it seemed you were lucky with that one. :) edit: This would break very fast because then circles r7c1 and r7c5 would have the same digits. So Simon would've spotted it pretty fast I guess.

[@Hybridrofl]

Yeah, R6C2 didn't need to be orange in his highlighting. It would have been 9 cells then, and would have left enough room for a 9 cell region in the bottom corner. edit: ha, good spot with your edit Tepalus... you're right, he'd have spotted it quick.

Wow! Took me about twice as long as you, but I did it! Feel proud to have made it through this one without needing any hints from the video. Especially coloring in the areas, which made me more than a little nervous that I might've messed up somehow!

[@shukryal-hilal3932]

I will say .... Thanks for making this one ❤️.... And thanks for solving it 👍

59.46 Another reason for cell R5C8 cannot be blue is that will make the line from R5C7 to C9 to become three 1-cell regions which are sharing the same digit in each cell.

Well. I watch these to fall asleep and it finally happened. I stayed awake and watched the whole dang thing!

1:38:00 ask yourself where the 79 in c2 goes in row 2. It must go in the green c18. So eliminate the 4 from that square which places the 4 in row 3 and also places a 4 in r2c2. You were just about there but not quite.

Thank you for a beautiful video of this work of art

Wow, that’s it, just wow. A few months ago I thought variant sudoku had peaked, it obviously hasn’t. Can’t wait to see what appears next……….

[@sakkikoyumikishi]

No time machine, sorry Simon. But it would appear that the next step here (29:49) is to replicate the "pink" logic in yellow. The yellow cell can't connect to the circle immediately below it, since that would make it impossible for another region to reach the line. The only(!) other circle that is close enough to be reached by the yellow cell, now that we've used up the circles in rows 1 and 2, is the circle in row 5. This, again, requires an efficient connection in order to not use up more than 9 cells. Which in turn means that part of the line in r3,c3/4 and r4,c4 needs to be in yellow, and the rest of it is likely in blue, since the yellow connection is cutting it off from the lower regions of the puzzle and we don't have enough space for a complete new region above yellow but below pink. By the same token, r2,c2 has to be yellow, since we don't have room for a different region to move in and grab it and the only other region close enough to pick it up (blue) would not be able to reach a circle if it extended to r2,c2. Maybe someone else has a time machine to get that info back to the time of recording 😂

Managed to solve it in just under 2 hours. Pretty happy with that today. Very clever puzzle.

[@ryanoftinellb]

I've seen so many of these that I'm starting to get a reasonable hit-rate on predicting the next colour he'll use. I knew Simon would use yellow at 23:47. And blue just after that.

[@bezowee]

Simon is so predictable yet it's take him so much time to pick next colour

[@Tahgtahv]

@@mjh4444444 I'm not sure what you're talking about. The upper region is color #F7BBF7, which is definitely a bright purple. Pink would be something like #F7BBBB.

[@Nevir202]

I almost got it, I predicted blue, and was wrong, but then I was sure it would be blue next and was correct. lol

[@jurjenvanderhoek316]

14:52 Not 32 line segments, but 32 cells that are part of a line: something totally different here, because a line segment is defined as that part of a line that belongs to one region, and therefore possibly has more than one cell.

[@euler4273]

At point 50:30, because there was indeed a way for that region to not be orange, if it took 8 of the squares from the 3x3, without the second circle, and the one next to the bottom orange square.

[@RichSmith77]

Simon didn't follow it through, but you end up with two 3s in the circles in row 7.

[@daleomiller]

Absolutely incredible puzzle 1:45:53

[@bass2564]

48:58 when you're so deep in a sudoku puzzle that you try to do sudoku using only three known digits, but then forget to actually use those digits for sudoku 🙂

[@PeterWTaylor]

Its got to the point where the hardest part of solving a puzzle is working out what the puzzle is.

[@elizabethshort9632]

I had to do the region building with Simon's help but proud of myself that I managed the sodoku bit once the regions were in. I really liked this one for a difficult puzzle as each bit of logic was rewardingly tricky but not exasperating.

[@asktheraccoon]

@49:00 “Why couldn’t there be a 3 in here ? *mouses over the 3s in the same columns* No reason at all” this is peak Simon

[@SpydersByte]

oh man that section where he finishes the green and blue and orange was PAINFUL. Now, I dont want this to come off like "Im smarter than Simon" because I wouldnt have even been able to get this far in the first place, and I know he always tries to thoroughly prove or disprove something and that can sometimes be why he seems to be missing the obvious but I couldnt help wanting to shout at the screen on numerous occasions in that short time span. Like not noticing the green couldnt take just a single cell from the bottom left line because it would equal the cell above it, or that it couldnt be a 1/4 split cuz of math (despite using that exact logic on the bottom right line), or that green had to be the one picking up the bottom right line cuz otherwise it'd have to be either the 3 or the 4 that was directly above it, only for him to stop working on it and shift over to orange for a minute >.< lol Im just glad it finally got resolved :D

[@iceblade732]

solved in 49:54 absolutely astonishing this one! I got the cages in just 21 Minutes, and am absolutely bewildered that I got them so much faster than Simon!

[@deltaangelfire]

i hope on april 1st, Simon does an entire sudoku while being handed notes or messages "from the future" that tell him where he should look next :P

[@kr12a2y]

We need another entry in the Saw franchise where jigsaw is like "I want to play a game." It cuts to Simon, and 90 minutes later everyone escapes unscathed.

[@ServantOfSatania]

87:48 Beautiful puzzle, got a bit stuck early after early breakthrough but 3s came to my rescue and finished the region finding part

[@markwizy4661]

Wait until someone sets a puzzle with this rule set and allows diagonal lines. Then we can have a two-cell line!
