For anyone confused this may help: This is a version of Sudoku called Killer Sudoku and is a game mode in competition (Yes, they have those for sudoku. These are the rules: All squares must have a 1-9 All rows must have a 1-9 The cages (dotted lines) cannot have two of the same numbers in them. The numbers in each cage must add up to the number in the corner of each cage. All killer sudoku puzzles also start with no numbers so it’s insanely difficult to start the solve. I don’t care about likes, but please like so it can get to the top and can help people who are confused.
dunkin' donuts The dotted lines create smaller areas. The numbers inside the dotted lines add up to the number in the top left of that “area”. Hope this helps.

I hope this partly answers the question how these puzzles are constructed, which is asked a lot in other comments: It's a lot like solving the puzzle again and again with small self-given constraints and making setups that leave enough variability. And of course a lot of Trial&Error and experience how to set up some constraints in a way that gives you a desired result. For everybody who wants to read a little bit more about puzzle creation, I can recommend the Puzzlecraft book by Mike Selinker and Thomas Snyder. The idea for the start is not new, I have seen it multiple times before, even at competitions. Sudoku puzzles and most of it's variants are very gentle in my experience: As long as you don't have an obvious contradiction on the board, it's almost always possible to complete the board to a valid Sudoku solution. That means, if you used up all information you already put into the grid, it is very unlikely that you have an obscure contradiction that you don't see immediately. So you can proceed and in the end it's most often harder to find clues that resolve all remaining pairs, than guaranteeing that there is at least one solution left. Also if nothing else helps you can always make the solution unique by giving plain digits. So generally Sudokus are a very nice type to start creating puzzles yourself. (That's not true for types with lots of local interactions like Nonconsecutive. In a lot of cases you get unwanted "dots" towards the end, which sometimes you can't fix without starting all over. Nonconsecutive is veeery constrained, and you don't see all of the restrictions immediately.) Last, if you really like Killer Sudokus and Sudoku variants based on sums, here are two older variants of mine, which were very well received by the solvers, so I can probably recommend trying them. (And while you are at it, I can of course also recommend checking out some of the other 4000 handcrafted puzzles we have at the puzzle portal of Logic Masters Germany right now. :-) ) Odd-Even-Killer (medium to hard): logic-masters.de/Raetselportal/Raetsel/zeigen.php?chlang=en&id=0001SI Equal Sudoku (super hard, you have been warned): logic-masters.de/Raetselportal/Raetsel/zeigen.php?chlang=en&id=0001PM
I have literally no idea what’s going on. Why was this recommended to me? However, I definitely enjoyed watching it for some reason?? Keep on puzzling my friend
@@qc1okay well. One of the case of 23 lower right box is not in the 3x3 square. But obviously, I did not understand that twice the same number is not allowed in a box. As he uses this fact multiple times. My bad.
I felt my mind go through multiple carpet bombings of Intrigue, realization, and amazement as I had no idea what type of Sudoku madness I was looking at during the beginning of the video. I felt lost at first but everything made sense as you completed the puzzle. I haven't had so many "So, that is how that works!" moments in a while. This RUclips algorithm has got some moments and I'm happy this video popped up on my recommended.
Sometimes we need to humble ourselves and envy those with superior intellect and marvel at their marvelous puzzle solving abilities. With that said... I was lost, too.
@@freyjadourlavoie yea, sometimes you just forget how many brilliant people exist in the world, he is a genius when it comes to these kind of puzzels, i learned killer sudoku at least
It’s all simple arithmetic, combined with numerous tricks that you learn over time when regularly solving sudoku. I found the video very beautiful in that sense, especially the symmetry of getting the first numbers onto the board. I haven’t ever personally done any sudoku apart from the simple ones which require minimal lateral thinking, but I can certainly see how you can make such a seemingly simple puzzle into something quite intricate
That took me 25 minutes to find the 8-9 pair situation around the corner of the grid. I spent absolutely ages trying to understand my way in, attempted brute forcing a few options knowing that I was missing something, and nearly gave up before trying to understand the box around the edge and realizing the trick within. That's very clever, but exceptionally difficult to spot for someone like me who is far from a killer sudoku expert. I managed to solve it only 15 minutes later thanks to all of the crazy logic I had semi-deduced around the grid from my earlier work, but I imagine that 40 minutes in a competition setting would put me in dead last.
@@featherozone Each column or row adds up to 45 (1+2+3+4+5+6+7+8+9). So top row is 45, bottom row is 45, leftmost column is 45 and rightmost column is 45. If you add them all together, you get a total of 180. But corner cells are counted twice in this total (top right corner is both in the top row and the rightmost column, etc.). So the actual total of the edge area is 180 - (sum of corners). So 180 - (sum of corners) = 28+12+22+14+23+17+20+10=146. Which means: sum of corners = 180-146 = 34.
This is actually the first time I see a killer sudoku and I must say, you did a great job explaining killer sudokus and your thought process. I probably would have spent hours solving this one, but you made it so easy to follow, I rarely had to pause for a few seconds. RUclips suggested your video seemingly random to me, but now I'm looking forward to watching more of your videos. Thank you for introducing killer sudokus to me and sharing your thoughts so well!
At 8:17 you made a 50-50 lucky guess. Because the squares don't all have to be unique numbers; one of them lies outside the box. You could have 149 horizontal, with 123 stacking on top, totaling to 20 giving you 3 points of freedom.
I love your pacing on these. Fast enough to not be a drag, labouring the logic every time,but also making sure to explain why each tricky move works. I definitely enjoy sudoku a lot more now
I never saw a soduku puzzle like this until today! Thanks to RUclips algorithm somehow it popped up. I'll also try to solve this kind of sudoku puzzles from now on! You did a great job while solving i.e solving+teaching... Thank you!
You know how when you're really good at something, you can kind of see the trains of thought of those who aren't as good. This is the opposite, I'm alright at Sudoku and watching this is like seeing things I've picked up on when doing them but at a much more advanced level, it truly is awesome to watch
This was one of the most satisfying things ive ever stumbled into on the internet! Thank you for wrecking my sleep schedule. I'm gonna go find every sudoku solve video I can
Same haha, but it's not a matter of intelligence, it's just knowing the rules and being used to them. Everyone can do this once they have a bit of training
My brain suffered at first, then I understood the cages/gates things, then I remembered fully how sudoku worked and then I got into it. God this was a ride, at a point I was shouting at you through my screen because of a darn 7, killer puzzle and criminal mind, dude.
My dad loved sudoku and would solve puzzles like this, idk the difficulty but he passed away, but i feel like he was very skilled. i thoroughly enjoyed this video :)
i really struggle with getting the killer sudokus started, but once a couple of the early hurdles are identified (eg that mirrored 7 in the top right - without that being pointed out, i would have been stuck forever!) i really enjoy getting through these. That early arithmetic though - and using the geometry of the puzzle to figure out the sum value of the overhang cells ... still a bit beyond me! Love these videos, though - such a fantastic way to be shown the techniques. And I love how genuinely you adore these puzzles, how beautiful and astounding they are! Thank you for sharing
Wow!! That opening bit is wonderful! I took your suggestion and took a look at it before watching and I was just baffled! Major props to figuring that one out!
This was a pleasure to watch. Granted I could barely follow along with a lot of this logic and was kinda just blown away with your mental math skills. Now I'm off to figure out why youtube recommended this video to me, not that I'm really complaining.
I found the 7 in the top-left square before you but my pride quickly faded when I realized you solved 6 other numbers I can barely count to within the same time frame which did make me cry but only a little. 10/10 experience all around.
Great puzzle. Unfortunately my skills were not good enough to crack this one but entertaining solve. Would like more Killer Sudoku types on this channel to expand my toolbox for solving them. Keep up the great work. (Loving the app btw)
I understood just enough to feel like maybe I could one day pull this off. I meant to be asleep 20 minutes ago but I couldn't stop watching. Awesome stuff.
The initial step to get numbers into the grid is not found on the sudokuwiki killer solver, and thats definately some sort of technique that could be used to solve hard killers, finding a set of cells that form a single neat set of rows and columns to find the total value of the overlap... Could definately be added to a solver.
For someone who enjoys sudoku a lot & wondered whether there was a competitive sudoku or not, this video introduced a whole new world to me. Thanks, it was extremely fascinating
I had seen these before but never attempted one. This gave me some insight on how to solve, and I tried one today. Once you get a few solid squares, the extra information that is available really helps solve it.
I'm on level 34 of the cracking the cryptic app. Love it so much, definitely worth it. I cant wait for more levels to be released on there already. All the stars make the levels look so intimidating to me being an amateur solver but they are not as bad as they look. So much fun, thanks for taking away all my free time! Haha :) Love your videos!
To be honest and i’m really not joking, i understand everything this guy is speaking and it’s great when you understand, love it, i need to try this type of sudoku on my own, great video!
I did it by myself! I'm so proud!(im not sudoku solver, thanks youtube recommendations) Took me 2 hours(+breaks). But watching the vid after, good job explaining and noting your thought process in readable way.
I got the hang of it after a while and I decided to give it a go, so I copied what he had at the 22 min mark and it still took me almost 10 minutes to finish what he did in 3. This man's good.
I actually followed that better than I thought I would. Never saw Killer Sudoku nor have I ever tried to solve one. I was COMPLETELY lost at the beginning, but listening to your thought process made it clearer as you went on. That being said I'll probably never be able to do one of the myself in a lifetime or 4. Still an incredibly interesting watch.
5:00 into the puzzle, and Simon still hasn't spotted the starting point. Pausing the video to say that I'm pretty sure this is why the puzzle was rejected; the variance on solve times is going to be huge. The setter appears to have been showing off something clever, but it's not much of a test of sudoku skill to quickly identify it. I'm a far inferior solver (averaging about 2-3x as long on the average puzzle), but the box immediately jumped out to me as a hand-crafted part of the puzzle and I was sure that would produce a constraint before I even did the addition. I had the first two pairs within seconds.
This feels like a puzzle hunt puzzle to me, the core of it is the fact that there is a clever bit of logic to get you started, and otherwise straightforward puzzle solving for the rest of it.
Never got into suduko, didn't know what was going on the first 10 minutes, still watched the whole thing! So interesting to follow your thoughts and trying to understand. I know a little more now ;)
damn, I went from not understanding a thing to trying to follow up, then I actually saw minor things you spotted a second later and I was like: "damn, Im so smart" ...and then you just finished and my brain tried it's hardest to follow up. But yeah, I would have never found the start, but as you went on it actually kinda clicked in my head. Loved the video, even tho it made me feel pretty stupid a lot of times :)
What fun! And it seems to be much easier to solve compared to normal sudoku, because you have to logic out where the numbers might be, rather than having to lay out every possibility on a plain newspaper board.
I didn’t even know sudokus existed without some preexisting numbers in. I’m amazed how smart people are to figure this out. I thought I was cool knowing how to play minesweeper, worst I’ve ever dealt with in minesweeper was a 6 I think ahah. And here this guy is like “ah yes that makes 146 so these are 8-9”
Ah yes, the diplodocus did run across the screen with absolute passion when the tiger scored that three pointer to make it fifteen-love, that was a brilliant goal by the kicker

set the numbers free!
@@thememoryfish no, you are just cramming more numbers into those cages...
Don't be a seven. Don't support eating nines.
I've never seen a killer sudoku, so I'm pleasantly surprised I could follow all of that.
Allan Clayton same here
actually same for me. i like sudokus but have never seen this but it was relatively easy to follow
Same, i actually found it a lot easier than a usual sudoku for some reason
yea me to
but that beggining wouldve got me. I can only do Bormal sudokus
This was fantastic solving to watch. I'd never have thought of that corner trick that got you started.
OK for the corner trick. But I don't understand why you can not have 12314 in the lower right corner box...
@@qc1okay well. One of the case of 23 lower right box is not in the 3x3 square. But obviously, I did not understand that twice the same number is not allowed in a box. As he uses this fact multiple times. My bad.
Ah, the good ole corner trick.
Oh hai two months later. That was the only part I did get. I cry.
I saw it. Always look for blocks that can be put together into a rectangular or almost rectangular shape.
My brain is buffering...
I felt my mind go through multiple carpet bombings of Intrigue, realization, and amazement as I had no idea what type of Sudoku madness I was looking at during the beginning of the video. I felt lost at first but everything made sense as you completed the puzzle. I haven't had so many "So, that is how that works!" moments in a while.
This RUclips algorithm has got some moments and I'm happy this video popped up on my recommended.
I've just watched a 25 minutes and 33 seconds of someone insulting my intelligence
Sometimes we need to humble ourselves and envy those with superior intellect and marvel at their marvelous puzzle solving abilities. With that said... I was lost, too.
@@freyjadourlavoie yea, sometimes you just forget how many brilliant people exist in the world, he is a genius when it comes to these kind of puzzels, i learned killer sudoku at least
I dont play sudoku, but from watching this video its all pretty simple logic, like a rubix cube once you know the formula to solve it its way easier
It’s all simple arithmetic, combined with numerous tricks that you learn over time when regularly solving sudoku. I found the video very beautiful in that sense, especially the symmetry of getting the first numbers onto the board. I haven’t ever personally done any sudoku apart from the simple ones which require minimal lateral thinking, but I can certainly see how you can make such a seemingly simple puzzle into something quite intricate
And it was entertaining
That took me 25 minutes to find the 8-9 pair situation around the corner of the grid. I spent absolutely ages trying to understand my way in, attempted brute forcing a few options knowing that I was missing something, and nearly gave up before trying to understand the box around the edge and realizing the trick within. That's very clever, but exceptionally difficult to spot for someone like me who is far from a killer sudoku expert. I managed to solve it only 15 minutes later thanks to all of the crazy logic I had semi-deduced around the grid from my earlier work, but I imagine that 40 minutes in a competition setting would put me in dead last.
Pyromonkey83 perhaps you could explain to me the logic of the corner shoving, I replayed it and all couldn't understand how he got to the number 34
@@featherozone Each column or row adds up to 45 (1+2+3+4+5+6+7+8+9).
So top row is 45, bottom row is 45, leftmost column is 45 and rightmost column is 45.
If you add them all together, you get a total of 180. But corner cells are counted twice in this total (top right corner is both in the top row and the rightmost column, etc.). So the actual total of the edge area is 180 - (sum of corners).
So 180 - (sum of corners) = 28+12+22+14+23+17+20+10=146.
Which means: sum of corners = 180-146 = 34.
@@christianbarnay2499thank you. The 180 was weirding me out
@@christianbarnay2499 i was about to ask for someone to explain me that, thanks
Christian Barnay thanks a lot!
ha, i solved this puzzle in half the time
gotta love 200% speed on youtube
I did it even faster, skipped to the end, ha :D
That was so unbelievably satisfying to watch.
This is actually the first time I see a killer sudoku and I must say, you did a great job explaining killer sudokus and your thought process.
I probably would have spent hours solving this one, but you made it so easy to follow, I rarely had to pause for a few seconds.
RUclips suggested your video seemingly random to me, but now I'm looking forward to watching more of your videos.
Thank you for introducing killer sudokus to me and sharing your thoughts so well!
"Well, the first thing I notice"
Yeah I'm already lost.
Him: "Aaaah, *Nice*."
Me: "Wait, what, where?!"
Him: starts giggling like he's noticed something important
Me: OH FUCK HE CAN SEE THE *LINES*
21:16 was pretty out there
This dude is legitimately speaking a different language and I can't click away.
Sometime you drive me nuts when you miss an obvious line - but that was stunning logic to even start that puzzle. Kudos

@@tlep2979 Kodus.
At 8:17 you made a 50-50 lucky guess. Because the squares don't all have to be unique numbers; one of them lies outside the box. You could have 149 horizontal, with 123 stacking on top, totaling to 20 giving you 3 points of freedom.
I can’t believe I just spent 25 minutes watching this, but I’m high and happy

Me: I enjoy Hot Ones, Alec Steele, and Scott Manley
RUclips: Sudoku
Coincidentally, I enjoy all of those things as well. This was also very interesting. The algorithm must be on to something.
@@vprkng You should at least watch hot ones.
"Gosh I feel so slow" > Thanks for slowing down a bit or we wouldn't even have time to see anything
This feels like the scene from The Princess Bride, The Battle of the Wits. Basically just 25 minutes of watching Vizinni try and figure stuff out.
It was...inconceivable.
I love your pacing on these. Fast enough to not be a drag, labouring the logic every time,but also making sure to explain why each tricky move works. I definitely enjoy sudoku a lot more now
Him: starts filling in numbers

RUclips: Time to spin the wheel of recommendations
you clicked so youtube won with that recommendation
Sometimes you get some gems.
@@marlonyo
I clicked because it was so odd.
I throughly enjoyed myself though
I was happy to solve it in 1:20. Then the happiness went away when I saw the ease with which Simon went through the puzzle after a rough start.
Got a good chuckle out of the repeated pattern of "and if you do all that you get -- this, which isn't very useful" at the start.
Who are you and why are you in my RUclips algorithm? And why do I find this video so soothing to watch and listen to?
this progression of logic was great! one of my favorites, thank you!
21:22 - look at that smile.
look at that lovely smile
I never saw a soduku puzzle like this until today! Thanks to RUclips algorithm somehow it popped up. I'll also try to solve this kind of sudoku puzzles from now on! You did a great job while solving i.e solving+teaching... Thank you!
You know how when you're really good at something, you can kind of see the trains of thought of those who aren't as good. This is the opposite, I'm alright at Sudoku and watching this is like seeing things I've picked up on when doing them but at a much more advanced level, it truly is awesome to watch
This was one of the most satisfying things ive ever stumbled into on the internet! Thank you for wrecking my sleep schedule. I'm gonna go find every sudoku solve video I can
You have no fucking idea how super human I feel right now for actually being able to follow his thought process.
Same haha, but it's not a matter of intelligence, it's just knowing the rules and being used to them. Everyone can do this once they have a bit of training
@@fifinoirdefer9458 and by everyone you mean only about a thousand out of the entire population so no :)
@@Trails3rdFanboy No no honestly more than that ! But I can be wrong, that's just what I think
@@fifinoirdefer9458 there is no way more than 10 000 people can follow killer sudoku to this guys extent so no you are still wrong :)
@@Trails3rdFanboy Are you projecting?
I genuinely smiled and mimicked him while finding the numbers, never watched a sudoku video befote, not a good sudoku solver, yet i enjoyed. Thanks
My brain suffered at first, then I understood the cages/gates things, then I remembered fully how sudoku worked and then I got into it. God this was a ride, at a point I was shouting at you through my screen because of a darn 7, killer puzzle and criminal mind, dude.
Why was the voice and the clicking and the intellectualizing so satisfying???
I have no idea what happened but I loved watching it
My dad loved sudoku and would solve puzzles like this, idk the difficulty but he passed away, but i feel like he was very skilled. i thoroughly enjoyed this video :)
i really struggle with getting the killer sudokus started, but once a couple of the early hurdles are identified (eg that mirrored 7 in the top right - without that being pointed out, i would have been stuck forever!) i really enjoy getting through these. That early arithmetic though - and using the geometry of the puzzle to figure out the sum value of the overhang cells ... still a bit beyond me! Love these videos, though - such a fantastic way to be shown the techniques. And I love how genuinely you adore these puzzles, how beautiful and astounding they are! Thank you for sharing
21:20 That is pure joy right there. :) Love it
Wow!! That opening bit is wonderful! I took your suggestion and took a look at it before watching and I was just baffled! Major props to figuring that one out!
This was a pleasure to watch. Granted I could barely follow along with a lot of this logic and was kinda just blown away with your mental math skills.
Now I'm off to figure out why youtube recommended this video to me, not that I'm really complaining.
I found the 7 in the top-left square before you but my pride quickly faded when I realized you solved 6 other numbers I can barely count to within the same time frame which did make me cry but only a little. 10/10 experience all around.
Great puzzle. Unfortunately my skills were not good enough to crack this one but entertaining solve.
Would like more Killer Sudoku types on this channel to expand my toolbox for solving them.
Keep up the great work.
(Loving the app btw)
I understood just enough to feel like maybe I could one day pull this off. I meant to be asleep 20 minutes ago but I couldn't stop watching. Awesome stuff.
After 9 minutes I finally understand how this board works. But I dont have the brain power to do it.
The initial step to get numbers into the grid is not found on the sudokuwiki killer solver, and thats definately some sort of technique that could be used to solve hard killers, finding a set of cells that form a single neat set of rows and columns to find the total value of the overlap... Could definately be added to a solver.
For someone who enjoys sudoku a lot & wondered whether there was a competitive sudoku or not, this video introduced a whole new world to me. Thanks, it was extremely fascinating
I had seen these before but never attempted one. This gave me some insight on how to solve, and I tried one today. Once you get a few solid squares, the extra information that is available really helps solve it.
I'm on level 34 of the cracking the cryptic app. Love it so much, definitely worth it. I cant wait for more levels to be released on there already. All the stars make the levels look so intimidating to me being an amateur solver but they are not as bad as they look. So much fun, thanks for taking away all my free time! Haha :) Love your videos!
You can see the delight spread across his face with the breakthrough at 21:12
As a layman, you articulated your thought process really well which helped me appreciate what you were doing even more.
To be honest and i’m really not joking, i understand everything this guy is speaking and it’s great when you understand, love it, i need to try this type of sudoku on my own, great video!
I absolutely don't know why RUclips algorithms put this video in my recommandations but I don't regret clicking on it at all
I did it by myself! I'm so proud!(im not sudoku solver, thanks youtube recommendations)
Took me 2 hours(+breaks).
But watching the vid after, good job explaining and noting your thought process in readable way.
I got the hang of it after a while and I decided to give it a go, so I copied what he had at the 22 min mark and it still took me almost 10 minutes to finish what he did in 3. This man's good.
I've heard of sadoku a lot but this is my first time ever seeing anyone doing it, absolutely no clue what's going on but I like watching you do it
I never knew how to play sodoku but watching his thought process showed me how to play and what to look for. Great video
man i had no clue what was going until about 9:00 and then i felt like matt damon in good will hunting
I actually followed that better than I thought I would. Never saw Killer Sudoku nor have I ever tried to solve one. I was COMPLETELY lost at the beginning, but listening to your thought process made it clearer as you went on.
That being said I'll probably never be able to do one of the myself in a lifetime or 4. Still an incredibly interesting watch.
"I feel like I'm being so slow here"... You're not. My jaw is on the floor for this solve.
What a joy to watch this puzzle starting to crumble! I stared at the puzzle for 5 minutes and just had to give up.
"Never go in against a Sicilian when death is on the line!"
I know so little about Sodoku - but I can tell you're absolutely brilliant
5:00 into the puzzle, and Simon still hasn't spotted the starting point. Pausing the video to say that I'm pretty sure this is why the puzzle was rejected; the variance on solve times is going to be huge. The setter appears to have been showing off something clever, but it's not much of a test of sudoku skill to quickly identify it. I'm a far inferior solver (averaging about 2-3x as long on the average puzzle), but the box immediately jumped out to me as a hand-crafted part of the puzzle and I was sure that would produce a constraint before I even did the addition. I had the first two pairs within seconds.
This feels like a puzzle hunt puzzle to me, the core of it is the fact that there is a clever bit of logic to get you started, and otherwise straightforward puzzle solving for the rest of it.
I done like 10 sudokus ever. I have no idea why this was recommended, but I enjoyed watching this instead of doing my homework.
Awesome work, I honestly was stuck until you uncovered the corner solve.
I don't know why this was recommended to me, but now I want to get my hands on these puzzles myself. Thanks for the vid.
Never got into suduko, didn't know what was going on the first 10 minutes, still watched the whole thing! So interesting to follow your thoughts and trying to understand. I know a little more now ;)
damn, I went from not understanding a thing to trying to follow up, then I actually saw minor things you spotted a second later and I was like: "damn, Im so smart" ...and then you just finished and my brain tried it's hardest to follow up. But yeah, I would have never found the start, but as you went on it actually kinda clicked in my head. Loved the video, even tho it made me feel pretty stupid a lot of times :)
Don't stress, I have a high IQ and I couldn't follow him at all. Im just high and enjoying a man in his element
nice algorythm xD
Watched first time, got nothing
googled rules
watched again, and now i am impressed, going to play these kind of sudoku by tomorrow
WHY WAS THIS RECOMMENDED BUT ITS LIT ANYWAY.
I want this guy on my pub quiz team
first time watching sudoku on yt but you made great content man. Enjoyed it
6:33 "Lets just do this arithmetic and see if this comes to a useful total" pretty much sums up whole video lol
It's funny rewatching this almost a year after it was released. Simon has become so much more comfortable and funny when being on screen!
At first i was like "tf is this? " and after 16 minutes in I am like "I LOVE IT"
What fun! And it seems to be much easier to solve compared to normal sudoku, because you have to logic out where the numbers might be, rather than having to lay out every possibility on a plain newspaper board.
To be honest this is my first time watching the puzzle... It's very good.. I excited to see more
First of all, why tf is this in my recommendations, second, why is this so satisfying to watch 😂
This man's IQ level is god tier
even following how you did it it was hard. but at the same time it was fun to follow along and do it "with" you.
I’m glad this dude found something that satisfies and entertains him so much
I never thought I could witness such childlike joy in a man doing a sudoku
I dont even know sudoku but his voice is oddly satisfying to listen to
Ah, the good ole corner trick. Brilliant move sir. I have no idea why, but it was brilliant!
I didn’t even know sudokus existed without some preexisting numbers in. I’m amazed how smart people are to figure this out. I thought I was cool knowing how to play minesweeper, worst I’ve ever dealt with in minesweeper was a 6 I think ahah. And here this guy is like “ah yes that makes 146 so these are 8-9”
Ah yes, the diplodocus did run across the screen with absolute passion when the tiger scored that three pointer to make it fifteen-love, that was a brilliant goal by the kicker
Never seen a sudoku like this before but this made me intrigued. Very interesting puzzle, cool seeing your analysis
I watch your videos for your calming voice and the puzzles are also interesting
Never done any sudoku with these cages before. I did it mostly by myself but I had to refer to your video every now and again for hints.
