This was in my recommendations. I don't even play Sudoku. And yet, I was taken on an adventure by this lovely man. He showed me the solution to a hard sudoku puzzle and I was interested and even laughed a few times along the way. I never thought the soothing voice of a grown man paired with a puzzle game I don't even play could bring me any form of joy. What a strangely wholesome video, thank you!
Shit, I didn't even realise the whole "pair" thing was something that you could work out. Should've been obvious but I just never knew. Thank you, random youtube recommendations, and thank you, CtC.
@@josephle5373 Mind blown tbh. I've watched a few of their other vids and I'm less capable of wrapping my head around some of the other methods, but this pair thing is so painfully obvious, it's easy to understand.
College for me but yeah, same thing lol It's kinda creepy how RU-vid can guess with good accuracy what we might like to view next. Often times it is something I haven't thought about or done in years.
So I was taught how to solve sudokus with my Nan when I was very little, I’d only do the easy ones obviously and I never really seem to finish anything harder than a medium even now. But watching you do that and learning about that little trick (I never even used to utilise the pencil thing) really made me think about my Nan and smile. She passed away four years ago now and was a huge part of my life. I don’t quite know how this got on my recommended but I really really needed this. It’s odd how these things work. Thank you for making my day in the most unexpected way!
I actually managed to complete the puzzle. It took me much longer than you did though. It took me over an hour, but I am still proud that I finished it on my own.
A year ago I stumbled upon this video by pure chance. I've never even played sudoku before. Somehow I ended up watching the whole thing, got hooked on sudoku, subscribed to Cracking The Cryptic, started solving sudokus every day, even got into Sandwich, Thermo, Star Battles, Kakuru, Akari, you name it.. And almost a year later, I'm still subscribed. It's crazy how the world works.
@@BriarDaisySkye : Yes i enjoy trying to solve 'em but honest i do struggle with some or fail to finish. I understand X wings but jellyfish and things like that are beyond me. Have you tried 'Sudoku X' they get the brain working for sure.
Just downloaded a sudoku app 4 months ago. I’ve been having a ball with that (it’s especially easy because it color codes each digit to help better identify) but I’ve been having trouble with books. I came here to find some inspiration since one particular book’s FIRST PUZZLE has me stumped! I wanted to see an experienced strategy, so I copied this puzzle onto a scrap of paper in pencil and pen and tried it before watching. When I got stumped, I’d push play. When you had a run of numbers, I’d write them in a different color and pause so I could understand why you found it and I didn’t. I would also take the numbers you gave and try to solve again, and once I came to a stop, I pushed play again. All in all, you gave me 12 numbers (which I don’t know if that’s good or bad) and I was able to solve the rest! It’s given me a few new strategies to apply to my game and was a fun way to learn. Thanks!
It was great to see how you uncover hidden pairs. I put way too many numbers as possibles in the boxes and confuse myself. Your way lessens the confusion so I’m going to try it.
I've been playing sudoku when I can't sleep, it ends up keeping me up even later if I can't solve it. I like the big brain solutions you guys come up with!
Mark at 6:27: "Well done if you're picking up the next stage ahead of me, that's quite possible, we're not superhuman." Me: Indeed not, but I am sleepy human.
Sudoku is so great. Thanks to this channel I got into sudoku a couple weeks ago and all my free time has gone into it since then. The moment when you see a logical connection between the numbers is just so exhilarating, it’s very addictive. It’s like you find the one domino that can be knocked down and everything follows from that discovery. I always have loved puzzles and getting into sudoku has been such a treasure because it truly is the best puzzle game ever, in my opinion.
Just posting to say that I started watching this video to try and help me a little more in playing Sudoku on higher difficulties. About half way through I said to myself "this isn't showing me anything at all" stopped watching and went to play a harder game. I actually ended up using the method you showed and solved the puzzle in about 14 minutes with no errors. So sorry for dismissing your video, and thank you very much, it was actually really helpful 👍
I am an occasional Soduko fan. Suddenly decided to look it up on RU-vid. Watched a couple, then found this. The hard ones take me a long time. The pairs in your solution are a BIG help. Thank you!
For some reason a two year old video of yours came up in my recommendations. I started watching the channel not long after this, a few months before the plague began, and it's interesting to see what we called kind of hard, back then. Pairs being the key to a puzzle is such a quaint concept to me, now, living in the age of the Phistomefel Ring.
I do appreciate the pairs technique that you use. I usually solve comparatively quickly, but I have not ever made the decision to only note pairs. Instead, I note everything and then start visualizing pairs and eliminating notes based on the pairs. It will most likely be a time saver to instead only note pairs. Thank you.
This was so impressive! I always neglected this pencil option but obviously I simply wasn't advanced enough to understand it's full meaning. I need to go find my sudoku puzzle magazine immediately!
Well, I'm greatly reassured. I never thought to look at RU-vid videos to do Sudoku (I mean not something you'd guess would be there), but go this lot on my feed and had a look. I have worked out exactly the same pattern of doing it. The things I am learning here are now the stasis-breakers, like the X-Wing and Y-Wings, and that's what I needed to go forward. Thanks guys...
This is the first time I've watched an older CtC video, and I'm amazed at how much _younger_ Mark looks today. I don't know if it's the camera, the kids getting older, or if he's just going back in time before our very eyes and that's why he's so good at solving puzzles. Anyway, it's a lot of fun to see how much the channel and the techniques have evolved. Well done!
@arnab ray I consider myself a little bit above beginner. I came here to learn additional skills especially to tackle the diabolical ones. I want to do less jottings and notes.
By golly gosh, you work these out fast. I was completing the sudoku with you. I worked out as much as I could then unpaused the video to get some hints then paused again to see how much more I could do. Needed your help twice. Great video. Learnt a new technique to sudoku.
Watching you solve this puzzle was VERY informative and AMAZING My sister had bought a sudoku puzzle book for my mother. She and I were able to solve the level one and level two puzzles with little difficulty, however when we got into level three, it felt like the challenge got up to a TOTALLY DIFFERENT LEVEL. I looked up only, typing “how to solve hard puzzles” and read that writing down the possibilities was the key to solving hard puzzles, and never really understood what that meant. Seeing you solve this puzzle really showed me the power of writing down the possibility in each box Thank you VERY much for uploading this video
Now, I'm more of a "solve sudokus on the toilet" person, but wow, that's the kind of puzzle I'd plug at for days before solving it, and you solved it in minutes! Though I do take comfort in the fact, that at least I seem to know all the techniques; I'm just way too slow :D
This was brilliant. I do play sudoku sometimes but I suck at it most of the time and give up. This was enlightening and very entertaining. Thank you!!!!
RU-vid for the win ... matching out-of-the-blue recommendations and people. Thanks CtC for uploading this elegant solution. Subscribed (for the moment when I thought 'what happens if he puts in the wrong number?' and yes, it turned into a red 6)
very helpful! i've always avoided the harder ones because i wasn't sure how to solve them, but keeping notes of the possibilities would help any puzzle get done faster it seems
@@MyReligionIs2DoGood I like it better without using the pencil marks. As you can see towards the end when you've penciled in the pairs you've 'solved' it at a way earlier stage, since the puzzle element falls away at that moment and you just look for what pair now clashes with new info. having to remember, or refind the pairs if you've lost them makes solving sudoku's more enjoyable and rewarding to me.
@@leonb4027 So, don't use the pencil marks; he is saying you have to use them. Some of us are unable to do this sort of puzzle at all. I am the numbers equivalent of a person with dyslexia. Once numbers are scattered, my brain cannot put them back in correct sequence. Seeing how to over-come that is very helpful. I am sure there is something I can do far better than you but as we are all different, I would not feel the need to belittle you for it.
That is not cheating. What would be the point of cheating anyway? If you feel you have to solve the newspaper puzzles to impress someone else, then just wait for the solution in the next days paper. Now that IS cheating.
@@PetroicaRodinogaster264 That’s weird. If you have dyscalculia why would you not use/know the name for it? And you seem a bit over sensitive, nobody is belittling you. If somebody said they felt like when they used a recipe was “cheating” when they were cooking they wouldn’t be belittling or even talking about you at all.
Im very new to sudoku but I love it, learning very quickly and it's very rewarding to spend 30 minutes up to an hour on a hard puzzle to finish it. The pairs technique will help a lot because I find that eventually I'll be stuck on the harder level puzzles but have a lot of pairs that now i know I could've easily figured a lot of placements out had I have known. Thanks for the video with the explanations as to why things must go where they do and your whole thought process.
You should work for television , talking in documentaries, the voice fits! :D Thanks for the method, I think it'll come in handy soon, even if I came here by coincidence :D
You can also use addition, each box should be equal to 45 and each line horizontally or vertically is the same then it just leaves you a process of elimination where you should put the numbers without overlapping the same number.
Never thought to find a Sudoku Play Through/Let's Play. Subbing because I play the game in my phone, but just recently getting on to Medium. May have to challenge myself more in that level in record time before moving on to Hard.
playing on my phone aswell everytime I'm on the train. Playing on hard, which is pretty much exactly like the one in the video. While I manage to solve those in 5-15 minutes I never manage to solve the expert ones :( atleast not consistently. I have to add I came up with the method used in the video by myself playing from beginner up to hard and I want to keep finding my own solutions for expert aswell. Finding new methods to solve the sudokus easier is what makes it so fun to me. Don't wanna google and see how it's done.
I have started with sudoku 40 days ago and l've looked for some tips first time today. This video came out and l'm so happy to discover it and this channel too. Thanks 😃
Didn't follow the same path but same reasoning & got it solved pretty quickly. Didn't learn new techniques as I hoped though, because some are harder to solve. Thank you.
This was a fascinating video to watch (I did twice). I tried the puzzle before viewing and got stuck. Re-doing it now that I've seen the gentleman expound on finding and making use of "pairs' should make it a little easier -- spotting these patterns is the kicker. Rather than trial numbers in cells, my method with a pencil is to place tick marks in cells according to the number; across top of cell for '1' - '2' - '3' then across center of cell for '4' - '5' - '6' and bottom '7' - '8' - '9' I don't have a program like the one used in the video. Thanks so much for the recording.
Hi. That is the same method I use. I take a daily newspaper just for the puzzles. One paper does two puzzles. Hard and easy. For some reason I usually solve the hard one but not the easy one. Does anyone have an idea why this might be?
Never forget the power of the pairs!!! Im trying to get better at soduko puzzles ive been doing them ever since i was 8 years old. Ive never thought about this way so thank you!
It was fun seeing the thought process of another sudoku solver, but also really frustrating seing stuff before you found them just waiting to see when you'll notice
7:43 I was stuck until that moment where you added the four, probably because I had covered the sudoku with potential marks that leaded nowhere like the potential nines in the bottom line (left corner) with the eights and fives, then the hidden pairs gave me the ultimate key to solve it. Very nice puzzle!
I never played Sudoku nor do I know the exact rules but you've got number 4 in the middle of the second column and in the fourth . It just doesn't seem right.
First time I’ve watched a sudoku video. I was surprised that I had figured out the same way to solve puzzles as the person doing the video! We must think alike!
There was only 4 numbers that could have gone there on the vertical line, 4, 6, 7, and 9...if you look horizontal 4, 7, and 9 are there leaving only 6 available
I like the fact that you explain your reasoning, the other chap doesn’t always take his time and explain which leaves me trying to catch up all the time, much appreciated thank you 😊
@@mihaihrincescu47 Did that. Was not the first link. "Hudoku is basically the same as Sudoku only with horse pictures instead of numbers." sites.google.com/site/horseisle2/mini-games/hudoku Hodoku, the second, link is similar to the app in the video. I installed it and it does not all user entry of pencil marks.
I've been following this channel for a while but didn't get back to this one until now. I copied it and I'm very proud that I managed to solve this almost as quickly, by using slightly different techniques but also relying a lot on CTC tips.
