Hey Brock, back in the day, I used to need help with NYT hard puzzles, but just finished this one without much fuss. Like most things, it's a matter of practice. CTC does a number of videos highlighting basic techniques that are very helpful. I can also recommend this website for a comprehensive listing of simple to extremely complex solving methods: hodoku.sourceforge.net/en/techniques.php. Hodoku is a computerized tool that you can use to solve puzzles or build your own. It will even give you hint's when you are stuck. Good luck!

I love all the puzzles you guys do because regardless of the difficulty, you're both so eloquent! But the hard ones especially are really satisfying to see cracked!
I do like when you go through some more manageable puzzles. I’m an amateur puzzler who wants to get better. I was hung up on the naked single on 1, but that unlocked the triples for me and I was able to finish from there.
Fuquan Tiegermann def check out their app. I had to use bifurcation on more than a couple of their puzzles because man are some of them pushed, but they give useful tips when you finish them that are really useful when going back to practice. I still have a couple other apps for when I just want to crush an easy puzzle but theirs is a good learning tool.
Fleaship column 8 has 123 56 9, you get the 4 and the 8 from row four, that only leaves 7. Or like how does he see it so fast because yeah the man’s a beast.
28:15 Pretty straightforward actually (that's really fun, like, 2 months agog I lever would have solved it, and now I'm doing it in half an hour, the quarantine really improved my skills)
I enjoy the mix of puzzles, but especially those, like this one, that I can solve on my own. I can often spot triples, x-wings, sometimes 'bent triples/Y-wings' and sometimes 'W-wings' but some tricks like Swordfish, x-y chains, w-x-y-z- wings, and things like that are still beyond me! I'm also still getting into thermo and knights-move sudoku, and am enjoying those (though still getting the hang of them). Killer and sandwich sudoku are interesting to watch, but I haven't tried many myself, I think they're still a bit out of my league at the moment. Keep up the great posts, and I hope you and your families are staying safe!
I'm far worse than you, don't know any of these techniques. Still, I've been playing sandwich and they are SO MUCH FUN. Give it a try, it's not out of your league.
I can spot swordfish and jellyfish if I am methodical (which I am because otherwise I wouldn't find anything). But I've never in my live found a bent triple.
@@sunriselg I oftgen start by noticing when there are two cells in the same block, row, or column that have two possibilities each, and one of them is the same number. That encourages me to look around for a cell that would complete the triple/Y-wing. Anything beyond that I usually can't find, though. Finding 'sashimi' fish patterns is still hard for me, even with X-wings, though I'm getting better at 'finned' X-wings, sashimi and otherwise.
22:35, about fifteen minutes to spot that damn triple... but today I solved all 3 puzzles by myself ( finally XD ) Obviously keep doing the puzzles that you like the most, but sometimes give us ( give me ) some manageable ones, thanks :D
I love the mix of different difficulties you guys feature. One thing I would say is that I'd love to see a bit more of the unique variations (especially if there's multiple at play! like Starcraft as an extreme example but even just thermos + a cloned shape or any combinations like this in the same puzzle) that are only taking you guys ~20 minutes to solve. I notice quite a jump in difficulty on the ones that you guys feature that take you more like say 25 minutes and up, it usually means you had to really work through a bunch of tricky stuff. Of course it's a spectrum but when I see a 19 minute video I'm eager at what should be a satisfying solve for me, when I see a 28 minute video I better grab a coffee as this is going to be long struggle! Both are nice...but would love a bit more of the former in the form of the variants as opposed to the sufficient amount of < 20 minute classic sudoku solves already present here :) Cheers
I must admit, I can't understand why people are obsessed with how quick they can solve a puzzle. For me (and it is fairly rare for puzzles on this channel) the joy is to complete it, click on 'Check' and seeing the lovely message "Looks good to me!" appearing. I can never get anywhere near the times of Simon or Mark. Well done for the perseverance, I would have given up, long before your time.
@@chrisg6597 Thanks. And yeah, it's all about the satisfaction of having solved it on your own. I'm just mentioning my time because there was one, and because it illustrates sort of how difficult it was.
I'm really new to puzzle solving and prior to finding this channel I wasn't even aware that there were other types of sudoku than classic, so I love the videos that are more manageable! They let me sharpen my skills and learn to spot tricks for solving that would otherwise have gone way over my head, and make it so I can work up to the harder ones!
Did this one in 12:52 here. For the videos, I appreciate a mix of the wacky insane hard stuff and more casual things like this, personally. The hard ones are a fun test to see what I can keep up with and where I see things that you guys don't and *especially* vice versa. The more chill ones are just good fun in general.
I somehow managed to overlook the naked single and stared at it for an age, before noticing that only two of the 359 triplet could go in row 3 in box 1 and that that affected where the 1 and 4 had to go in box 2, and thus getting to the exact same position spotting the naked single would have got me. A bit like turning right three times to get to a destination, rather than left once. I enjoy the variety of puzzles you guys do at the moment. Specifically to the Sudokus, the variant Sudokus usually rely more upon logic specific to its extra restrictions, whereas the classics rely upon more advanced 'straight' Sudoku techniques, so it's really nice to have those different demands on the brain, and for a similar reason it's nice to have a variation in difficulty. Not only is it nice to brush up on the basics (like spotting naked singles...) but they act as stepping stones for people who are relatively new to the genre in order to bridge the gap between novice and savant.
Well I've been watching since the end of last year and this is the first time I've attempted a puzzle before watching it. After a couple of restarts, and a rather long time, I actually managed to complete it!
I was confused at the first or second 7 that was placed. Lockdown here in South Africa gets lifted on Friday, my life isn't going to change too drastically (I tend to stay in my home for the most part anyway) but I do still look forward to it.
I've been subscribed for a couple of months now and I'm really happy with the variety of content that you're offering. You've become part of my life! Everyday after my morning coffee I start cracking and it's always a suprise what I'm going to get! I personally love to solve the more logical variants like Thermo, Palindrome, Clone etc... The math variants aren't as enjoyable for me to solve, but I still enjoy watching you solve them , and I'm therefor still getting better at them. Throw in an occasional Starbattle, Starcraft, Aquarium or some other oddball and I'm happy. Keep up the good work!
I like the mix :) Sometimes it's nice to get tips on how to get better at normal sudokus, sometimes it's very satisfying watching someone cracking a (for me) completely impossible puzzle!
It was gratifying to see how similar my solve path was to yours, although somewhat appalling how much faster you got there than me! I like the mix of difficulties on the channel. Here's a suggestion of something that would help me. I do the NYT Hard puzzle every day. I'd like to see some sort of star rating of the puzzle you're doing that day on the channel, similar to the ratings assigned in your app. If an NYT Hard is maybe around a 5, I'd like to know how the daily channel puzzle compares to that. If nothing else but for my time planning.
57:55 Spent 50 minutes before watching the video for the breakthrough. I had pencil marks that could have resolved the R3C1 1 cell, which untangled everything
I tend to be more methodical in my approach, and I am not worried about my time. When I get a row, column, or box down to only three or four unsolved cells, I usually use Centre notation to fill in, cell by cell, the remaining possibilities for that row, column, or box. Doing this makes it easier for me to spot singles, pairs, or even triples. Sometimes, if I get stuck, I will use Centre notation to fill in even more rows, columns, or boxes. I did not see his 1-3-7 triple, but because I had used Centre notation on the entire remaining puzzle, I caught a 2-9 pair in the bottom row. This let me eliminate 2s and 9s in the bottom row, and solve the 6 in the lower left corner. I am very methodical about deleting pencil marks after I solve a cell, and the rest of the puzzle was easily solved by eliminating possibilities.
I prefer the harder puzzles, but that's because I've consumed all your content since you launched your web app (about a year ago?) and done all the puzzles myself while listening afterwards to commentary for when I found particularly hard solves. The commentary especially has helped me hone my technique so that I can see and apply even some of the more "advanced techniques" like X-wings, swordfish, and jellyfish (I still have problems spotting Y-wings, but I often find them with X-loops). But I'm fine with whatever you guys like to do.
Oh, and I think I like a good mix, personally. Something like this one with no "advanced" techniques but a couple of hard-to-spot singles and/or triples is I think perfectly appropriate. All the way up through the ones that break my brain in increasingly less pleasant ways, along with the few I don't attempt at all. Mileage will vary, but I think you have a pretty good grip on your target audience already. Just keep looking for puzzles that you yourselves find fun and/or interesting and you'll be fine. Edit: Oh, another comment reminded me that, if anything, I'd like you two to go a bit easy on the really complicated rulesets (to which unusual/unfamiliar puzzle types can belong for most viewers). They're not bad, just .. spread them out a little.
You can do this without the box 7 triple. The 4/5 pair in box 9 led you away from the fact that r9c6 was also restricted to 4/5 (using the exact same digits from the box 9 pair), which forced the 8 in r8c6. Then with the naked 1 in r3c2, the puzzle falls apart. Basically it was the same logic you used, except without needing to actually discover the triple. Satisfying solve either way! :)
I like the mixture of puzzle levels, this was great to be able to join along with you and attempt the puzzle! But it's also so satisfying seeing you guys crack some incredibly difficult ones!
New to the channel and I have really enjoyed trying to solve the puzzles on my own. I enjoy Classic puzzles such as this one, but enjoy watching the seemingly impossible puzzles as well. While I cannot solve those, I still learn from watching. I was able to solve this one, but I missed the set of three trick. Great videos and thanks for sharing!
This was indeed nice to do. There was another way of solving the bottom boxes which do not require the 1-3-7 tripple in left bottom box: The same could be done by identifying the 29 pair in row 9.
As much as I enjoy watching you solve absolutely mind-melting puzzles, I really enjoy and appreciate videos like this that help me improve my own skills.
16:29, took a while to spot a naked single, didn't need anything fancy. Interested to see the trick. Edit: im gonna answer the question at the start: i like the mix of hard and extreme. I also wanted to point out a solve without the triple. The 4s in box 2, 5 and 7 make a 48 pair in box 8. This pushes 5 to be in column 6 in box 5, giving the 5 in box 8, resolving the 45 (and 48) pair.
You actually didn't need to find any triples in this puzzle. If you go to the moment Mark finds the triple, take a look at options for 4s in the bottom-middle square. You'll notice it makes a pair with the 8s. Now take a look at 5s and you should be well on your way :)
I think a mix is good, watching you guys explain a puzzle that is something I can solve helps me learn more than watching you guys work through an insane puzzle, which is still fun to watch
Of the NYT hard you've solved on the channel, I think this is the first I've watched that I've been able to solve before watching, which... Yeah this channel is definitely helping my sudoku skills. Broadly the same order before untangling everything at the end, though for some reason I found the 268 tripple in the lower left box before the 137 and was able to get the 9 from that.
@@badguysephiroth619 yeah that threw me off for a sec too, but he explained it a little bit before that. In column 2 there are only 3 open squares and 8 cant be in row 4 column 2 so it has be in either r8/9 c2.
Always glad to watch Classic Sudoku solves. My vote would be for diabolical puzzles requiring advanced solving techniques. Keep up the fantastic work!!
Nice puzzle, I solved it first myself and then went on to watch this for alternate solutions. I spotted the 1 up in the top left box at approximately the same stage as you, but I didn't spot those triples the same way. Rather I solved the box in question in a slightly more cumbersome way. :-) I'd be glad to see a mix of puzzles of this difficulty level and harder. I don't care too much about the toughest ones though. They're nice to watch once in a while, but since I don't have the time or skills to solve them myself or maybe even follow the logic, I'd rather see more of the easier ones, showcasing different advanced techniques that I'm not too familiar with yet.
I thoroughly enjoy all you do. I like that you have a mixture of puzzles, many of which I can tackle with a few most definitely out of my pay grade. My solving skills have risen exponentially this past year or so, twelve months ago I couldn't even manage the simplest of Killer Sudoku's but now they are my absolute favourite Sudoku variant. In short, more of the same please. 👍
Happy I spotted that naked single! Totally by chance luck though Didn't need that triple to solve the puzzle btw. Besides that single, I did it with just doubles/normal sudoku
Both kinds are appreciated. If the puzzles are modified [where the instructions are too alien to me] I have to go through the tutorials a few times to get where you're going.
I love a mix, thanks. It is nice to have a puzzle that can make me feel clever. And a lot of the techniques were explained with the old software. The new software is much easier to use.
A mix is great. I would like to you both of you do videos on the same puzzle, as you both have awesome but different techniques and we can learn different things from both of you, and see which style suits us better etc.
i got stuck at one point and gave up but i can say that i'm definitely seeing and understanding more after watching your videos. just gotta keep practicing!
This one can be done without the triple. Just need to note that on the bottom row, 4,5 is blocked out for the full bottom left block and is blocked in column 9 from the top box, which means 4,5 can only go in cells 6 and 7. That then places the 8 in cell 6 in the row above. Simpler and easier in my opinion, but depends what you're used to I guess.
It is definitely nice to get a mix of mix of standard sudokus and the different puzzles. I do enjoy the variations quite a bit and it is good then to come back to a standard sudoku.
Managed to finish without spotting the triple but definitely needed help with spotting a couple of naked singles - I always slip up on these but Mark gets them like a pro every time!
43:01 Relative beginner, took forever to spot the naked 1 in r3c2 and for some reason stubbornly refused to check the triple in box 7... Brute force works, but is slow.
I'd like to see more of the hard and manageable puzzles. I like to do them before watching the video and if more videos are done of the ones that stretch you, then I won't be able to do them, which would kill the interactivity with me that this channel provides.
50:06 Was able to solve it without finding the triples but it took a lot longer! As much I like seeing the tricks you use to solve really hard ones, its nice to be able to solve one on my own once in a while.
As a newcomer to sudoku I appreciate you taking an experts approach to the NYT ones. I've been doing them while locked down but have to resort to the "hint" button sometimes. I'm learning lots from you guys. Thanks for the channel. Classic sudoku all the way for me at my level. Fwiw i find the NYT hard level harder than the websudoku evil level. May I ask what is your opinion of the websudoku evil puzzles? Cheers. Mart.
Thanks for this, it was really annoying me that I couldn't do it before. I prefer doable classic puzzles because it helps me learn. If they're too complicated I know I'll never remember that technique. The naked single 1 was the trick I needed here.

22:44 - not bad for this time of the morning (must wake up first! made a mistake). I was looking for the usual NYT row or column triple & didn't see one. Now to watch and find the trick I missed.
Oh I see, I didn't need the NYT triple near the end because I had the 48 pair at the bottom of column 6 and the 137 triple were actually the last squares in box 7.
I didn't manage to spot the hidden triple but I worked on box 8 row 8 and found a naked single 2 in C2R8. Snowballed the rest of the puzzle after that.
I didn't need those triples. At 10:52 those two cells are actually 48 pair, which was the key for me (together with 28 and 268 cells at column 2) to solve the puzzle.
10:36 The bottom right cell is mentioned to be a 268 while 6 and 8 are in that box. I had that bottom right cell narrowed down to a 2 or a 9 so when the 9 appeared at the bottom of column three I could put a 2 there, then a 6 bottom left cell and the 8 at the bottom of collumn two. Did I miss anything about the 268 theory?
I solved it a little differently than Mark as I never saw the triples in box 7. The 4s in Columns 45 were pushed into Rows 89 Column 6 making a 48 pair pushing the 5 into Row 8 Column 5. The rest of the puzzle was easy from there.
I don’t think I needed any of the ‘hidden triples’ but I did need help with the naked single 1 in box 1, and then I think I used the 48 pair in box 8 that Mark did not spot to get the rest of the puzzle. 12 minutes not counting the time watching the video up to the naked single spot.
I almost prefer nutzy puzzle that are actually insanely hard because that way I don't feel stupid when I don't finish them. WHen you guys put Hard NY Times puzzles, I never understand them and feel quite dumb after you finish in 7-8 minutes with 0 trouble! But more seriously, anything works, you guys are rock solid and I enjoy every single video you make!

Great video, I love the puzzles that seem impossible and you guys manage to solve them. I also love the intermediate ones too!

The 4/5 pair in box 9 led you away from the fact that r9c6 was also restricted to 4/5 (using the exact same digits from the box 9 pair), which forced the 8 in r8c6. Then with the naked 1 in r3c2, the puzzle falls apart. Basically it was the same logic you used, except without needing to actually discover the triple. Satisfying solve either way! :)
I like the mixture of puzzle levels, this was great to be able to join along with you and attempt the puzzle! But it's also so satisfying seeing you guys crack some incredibly difficult ones!
New to the channel and I have really enjoyed trying to solve the puzzles on my own. I enjoy Classic puzzles such as this one, but enjoy watching the seemingly impossible puzzles as well. While I cannot solve those, I still learn from watching. I was able to solve this one, but I missed the set of three trick. Great videos and thanks for sharing!
I only been doing suduko for a month now. I learned tons of new stuff. Thank you so much.
This was indeed nice to do. There was another way of solving the bottom boxes which do not require the 1-3-7 tripple in left bottom box: The same could be done by identifying the 29 pair in row 9.
Wow, first time I didn't find a puzzle insanely difficult, literally while solving I said out loud "what is happening why can I solve this"
These ones are better then the shape puzzles and ones similar to that. The puzzles with the nights move are very fun and enjoyable to watch as well.
As much as I enjoy watching you solve absolutely mind-melting puzzles, I really enjoy and appreciate videos like this that help me improve my own skills.
An easier straight sudoku like this is nice every now and then, just for a refresher on basic techniques.
After wathing the intro... I prefer a sudoku variant and other kind of puzzles. But every once in a while is good to see a classic sudoku.
16:29, took a while to spot a naked single, didn't need anything fancy. Interested to see the trick. Edit: im gonna answer the question at the start: i like the mix of hard and extreme. I also wanted to point out a solve without the triple. The 4s in box 2, 5 and 7 make a 48 pair in box 8. This pushes 5 to be in column 6 in box 5, giving the 5 in box 8, resolving the 45 (and 48) pair.
You actually didn't need to find any triples in this puzzle. If you go to the moment Mark finds the triple, take a look at options for 4s in the bottom-middle square. You'll notice it makes a pair with the 8s. Now take a look at 5s and you should be well on your way :)
I think a mix is good, watching you guys explain a puzzle that is something I can solve helps me learn more than watching you guys work through an insane puzzle, which is still fun to watch
10:17 I see the naked triple 137, but for the life of me I can't see how the 8 is eliminated from r9c1 in the remaining 268 triiple.
In column 2 we need an 8 it must be in r8 or r9 thats why he eliminates 8 from there.
@@talhaozdemir96 Thanks for the help! I missed that too
@@talhaozdemir96 I see it now. He discusses it @ 8:47. Thank you.
@@talhaozdemir96 Thank you, I was confused as well when he eliminated the 8
Of the NYT hard you've solved on the channel, I think this is the first I've watched that I've been able to solve before watching, which... Yeah this channel is definitely helping my sudoku skills. Broadly the same order before untangling everything at the end, though for some reason I found the 268 tripple in the lower left box before the 137 and was able to get the 9 from that.
Yeah, but how did he know there was no 8 in the bottom left, that 8 was crucial, and he took it out right away with no indicators
@@badguysephiroth619 yeah that threw me off for a sec too, but he explained it a little bit before that. In column 2 there are only 3 open squares and 8 cant be in row 4 column 2 so it has be in either r8/9 c2.
Always glad to watch Classic Sudoku solves. My vote would be for diabolical puzzles requiring advanced solving techniques. Keep up the fantastic work!!
Occasionally I do the NY hard Sudoku and as luck would have it this was one of those times. I enjoyed watching your solve.
14:57, happy with that. Spotted the naked single 1 in box 1 in about 30 seconds because of all the practice on this channel! Whoop!
Nice puzzle, I solved it first myself and then went on to watch this for alternate solutions. I spotted the 1 up in the top left box at approximately the same stage as you, but I didn't spot those triples the same way. Rather I solved the box in question in a slightly more cumbersome way. :-)
I'd be glad to see a mix of puzzles of this difficulty level and harder. I don't care too much about the toughest ones though. They're nice to watch once in a while, but since I don't have the time or skills to solve them myself or maybe even follow the logic, I'd rather see more of the easier ones, showcasing different advanced techniques that I'm not too familiar with yet.
I thoroughly enjoy all you do. I like that you have a mixture of puzzles, many of which I can tackle with a few most definitely out of my pay grade. My solving skills have risen exponentially this past year or so, twelve months ago I couldn't even manage the simplest of Killer Sudoku's but now they are my absolute favourite Sudoku variant. In short, more of the same please. 👍
I really like these "do-able" puzzle videos - Very fun to try and if/when I get stuck, I can watch for some help. Thanks
Happy I spotted that naked single! Totally by chance luck though
Didn't need that triple to solve the puzzle btw. Besides that single, I did it with just doubles/normal sudoku
Yeah, same. I didn't really understand the triple spanning across row 9 he did but the doubles let me go through that part without it so w/e
Both kinds are appreciated. If the puzzles are modified [where the instructions are too alien to me] I have to go through the tutorials a few times to get where you're going.
Seeing the "manageable" puzzles is good to learn more techniques which are usable for us who do not do the crazy puzzles you guys do!!
I love a mix, thanks. It is nice to have a puzzle that can make me feel clever. And a lot of the techniques were explained with the old software. The new software is much easier to use.
A mix is great. I would like to you both of you do videos on the same puzzle, as you both have awesome but different techniques and we can learn different things from both of you, and see which style suits us better etc.
i got stuck at one point and gave up but i can say that i'm definitely seeing and understanding more after watching your videos. just gotta keep practicing!
This one can be done without the triple. Just need to note that on the bottom row, 4,5 is blocked out for the full bottom left block and is blocked in column 9 from the top box, which means 4,5 can only go in cells 6 and 7. That then places the 8 in cell 6 in the row above. Simpler and easier in my opinion, but depends what you're used to I guess.
It is definitely nice to get a mix of mix of standard sudokus and the different puzzles. I do enjoy the variations quite a bit and it is good then to come back to a standard sudoku.
4 & 5 was a double in row9 since the start, wouldve solved the 8 in box8 way early
That's even prettier i guess. I used the 48 pair in box 8 to get a 5 in box 8 first.
I finished in around 13mins without noticing the triple in column 7. First time for me finishing so fast a hard puzzle
Managed to finish without spotting the triple but definitely needed help with spotting a couple of naked singles - I always slip up on these but Mark gets them like a pro every time!
21:02 on this one. Very enjoyable.
Thanks, I enjoyed this puzzle. I do prefer "hard" problems which are solvable for me.
Finished in 30 min ... so not too quick
About 40 minutes. I'm just slow at entering the numbers it seem because I encountered no issues. This one was rather simple.
43:01
Relative beginner, took forever to spot the naked 1 in r3c2 and for some reason stubbornly refused to check the triple in box 7...
Brute force works, but is slow.
Hardest puzzle.. SOLVED. Using Technics.amezing sie
I'd like to see more of the hard and manageable puzzles. I like to do them before watching the video and if more videos are done of the ones that stretch you, then I won't be able to do them, which would kill the interactivity with me that this channel provides.
50:06 Was able to solve it without finding the triples but it took a lot longer! As much I like seeing the tricks you use to solve really hard ones, its nice to be able to solve one on my own once in a while.
More Classic Puzzles please!!! Love the content!
23:39. I made a mistake pencilmarking the topleft box, so it took a while to find that 1. After that it fell apart quite easily.
As a newcomer to sudoku I appreciate you taking an experts approach to the NYT ones. I've been doing them while locked down but have to resort to the "hint" button sometimes. I'm learning lots from you guys. Thanks for the channel. Classic sudoku all the way for me at my level. Fwiw i find the NYT hard level harder than the websudoku evil level. May I ask what is your opinion of the websudoku evil puzzles? Cheers. Mart.
Thanks for this, it was really annoying me that I couldn't do it before. I prefer doable classic puzzles because it helps me learn. If they're too complicated I know I'll never remember that technique. The naked single 1 was the trick I needed here.
A mix of tougher and more manageable ones is what I would prefer.
thx much Mark and Simon for cranking out so much content during lockdown .. a great service ..

- not bad for this time of the morning (must wake up first! made a mistake). I was looking for the usual NYT row or column triple & didn't see one. Now to watch and find the trick I missed.
Oh I see, I didn't need the NYT triple near the end because I had the 48 pair at the bottom of column 6 and the 137 triple were actually the last squares in box 7.
I didn't manage to spot the hidden triple but I worked on box 8 row 8 and found a naked single 2 in C2R8. Snowballed the rest of the puzzle after that.
I didn't need those triples. At 10:52 those two cells are actually 48 pair, which was the key for me (together with 28 and 268 cells at column 2) to solve the puzzle.
19:19 I noticed the naked singles early, which are often time sinks for me.
Love these classic videos.
Variety is the spice of life, I think a mix of difficult and easy is very welcome!
17:06 Nice puzzle.
First one on this channel I've been able to do, 1:01:07
There was also a 48 pair in column 6, last 2 cells. You wouldn't have to find the triple in the box this way!
10:36 The bottom right cell is mentioned to be a 268 while 6 and 8 are in that box. I had that bottom right cell narrowed down to a 2 or a 9 so when the 9 appeared at the bottom of column three I could put a 2 there, then a 6 bottom left cell and the 8 at the bottom of collumn two. Did I miss anything about the 268 theory?
Thanks for the video, the link to play the puzzle is a great feature.
I solved it a little differently than Mark as I never saw the triples in box 7.
The 4s in Columns 45 were pushed into Rows 89 Column 6 making a 48 pair pushing the 5 into Row 8 Column 5. The rest of the puzzle was easy from there.
Same here
Thank you so much Mark
12:04 nice
One of the few I can actually do! Wouldn’t have been able to do it before watching this channel though
Your solving path is good, but you don't need to spot triples if you see the 45 pair in row 9 (from the beginning).
I don’t think I needed any of the ‘hidden triples’ but I did need help with the naked single 1 in box 1, and then I think I used the 48 pair in box 8 that Mark did not spot to get the rest of the puzzle. 12 minutes not counting the time watching the video up to the naked single spot.
Great video
I love the solving of the near impossible puzzles but I also like to have some that are solvable at my level
First solve in a long long time.
My favorites are the very tough Classic Sudoku. :)
Love you guys. Cheers.
I like the "impossible" puzzles
In the bottom row the 45 pair is actually there really early and lets you place the 8 right away as a result.
I almost prefer nutzy puzzle that are actually insanely hard because that way I don't feel stupid when I don't finish them. WHen you guys put Hard NY Times puzzles, I never understand them and feel quite dumb after you finish in 7-8 minutes with 0 trouble!
But more seriously, anything works, you guys are rock solid and I enjoy every single video you make!
I got to the digit in r8c6 by identifying a 48 pair in box 8 which resolves the 45 pair in box 9 and feeds back into the 48 pair
My vote is to keep up with the mix of manageable and difficult!
I spent about 20 minutes and found everything that Mark did up to, but excluding the 1 in box 1.
