His ability to remember what he did earlier always astounds me. If I hit the rewind button I have no clue what any of my earlier deductions were, but Simon seems to know exactly where to unwind to, what the deduction was and why it was wrong, almost instantly upon noticing an error. (Same applies to his ability to remember why he coloured a particular cell or cells, too - I'd have forgotten the significance of it within about 30 seconds as soon as some other logic distracted me...!)
@@chris5619 My guess is that it's a combination of raw talent that's been honed into a powerful skill over years, similarly to highly skilled chess players are capable of playing blindfolded games because their ability to visualize positions has been trained so much that they don't need a board in front of them to analyze a position.
9 times out of ten, yes. There have been times where he "logically" deduced something, rewound, and no idea what he was thinking, usually when the logic was completely nonsensical.
I've watched probably 100+ of your solves simon, dating all the way back to april or may 2020 when this was new. I'm normally a lurker, I don't comment much on any youtube videos, but that puzzle. That bordered on an almost religious experience. I don't know why but every deduction, every digit, even the mistake and fix felt so genius, I don't think I've seen so many brilliant pieces of logic line up one after the other like that and solved so smoothly! Thank you very much Simon for the journey and thank you Myxo for creating the most elegant sudoku I've ever had the pleasure of experiencing
Genuinely thank you, I always check if someone else saw the logic I did before commenting, and was concerned I missed something. Like, with the logic he stated, why couldn't the forced 1-6 pair be with, say, 9-2? Or vice versa? Am I on the right track?
@@plum2584 You're not wrong. Simon was using the whispers lines incorrectly at this point. The correct application would have been that if the thermometer was low, then there was a 4-9 pair and a 1-X pair, if it was high there was a 1-6 pair and an X-9 pair. The 4 he gets because of this logic is dirty.
The SET-fueled break-in was fascinating, not only because of what it actually tested for (highs and lows) but also for how quickly you identified it, Simon. What a video!
That was maybe the longest I've seen Simon not catch a mistake... but I'm glad because it makes me feel less bad about my own mistakes. Even if I felt really stupid for not understanding how the (not real) constraint worked for a bit.
A very lovely puzzle! I've been watching these every day for a while and it's inspired me to get out one of my Sudoku books I got for Christmas as a kid. It's one of those big spiral-bound ones with 300+ puzzles ranging in difficulty, and when I flipped through it the other day I found that I'd already done the first 50 back in high school by the looks of my handwriting! I've started carrying on where I left off, but now I'm dating them when I finish so if it's another decade or so before I open this book again I can see when I worked on them. I'm delighted to report that (although it probably wasn't necessary to solve the puzzle, since this early in the book they still only really require you to see naked singles) I found an X-wing, and actually used it to find a digit! I've spotted X-wings before, but never knew how to use them to eliminate possibilities in other columns. Thanks so much for getting me back into Sudoku again, and encouraging me to finally learn the techniques I wanted to know as a kid!
33:00 - Unless I'm misunderstanding, you didn't need to do the X-Wing to know that there were no 5 in the yellow cells in C1 or C9. The relative scale of the purple and yellow digits were the same, meaning equal numbers of low digits, equal number of high digits and equal number of 5's. The only 5 you had in purple was from the given 5 so once you figured out there had to be a 5 in a C5 yellow cell, then there couldn't be a 5 in any other yellow cell.
Your logic and the logic he used were both correct in eliminating the 5's from the other thermos. because no 5s could go on the german whispers. Simon just likes doing things the hard way because yours was alot quicker in eliminating the 5s
I saw it this way too. Since there are no pencil marked 5s in purple (and none on whispers) you know there is only one 5 in each purple and yellow so once you find the 5 in yellow (in the 1,5 pair), you can remove the other pencil marks for 5 in yellow. But Simon never does anything the obvious way!
I think what I loved most about this was the synergy of the clues. They all worked together throughout the solve and were always relevant, and you never needed to make guesses
At the 40ish minute mark, you can prove that both top left and bottom right thermos must be 6-9. If you make either 1-4, it places a 4 in Box 5, but that results in a clash of 2s in R3 or R7.
I came here to say this. But then Simon failed later to spot 2 4s in column 4 and instead ruled out his hypothesis by spotting 2 3s which he hadn't yet put into column 3! But I wish I was half as clever as he is!
1:11:33 Could We Do Better With A Digit Like Six will be an excellent song title when you get around to making Cracking The Cryptic: The Musical. Could we do better with a digit like six? Is it the right tool in our arsenal of tricks to help us bounce back from the punches and kicks; oh could we do better with a digit like six? Yes could we do better with a digit like six? Will it be the figure that finally sticks from our possible pot-luck of nine number picks? Perhaps we'll do better with a digit like six... And if we do better with a digit like six, will we find the logic all suddenly clicks and speed through the cells we have still yet to fix? Let's hope we'll do better with a digit like six. So could we do better with a digit like six-o, and prove ourselves to that maleficent Phisto by cracking this cryptic conundrum from Myxo; oh could we do better with a digit like six-o?
Hmmm: Cracking The Cryptic: The Musical -- I like it. Simon would be a tenor, Mark a baritone. Do we bring in famous setters as other characters, and to get some higher voices? Is Jay Dyer a soprano, for example? We need a chorus of dancing digits, naturally, and of course a great big airplane, audible throughout and finally becoming visible at the start of the big number mid-way through Act 2. 😸
I saw quickly how to make the sets, I saw what it did with the thermometers. I saw how the thermometers looked at each other to make the central 2 thermometers different from either of the outer ones. I just could not wrap my head around how tobuse all this insight to break open the puzzle. I stared at the grid for 2 hours across 3 days, but just didnt get the logic straight. Then i watched the video. Thinking about low and high digits definitely was the key that I never figured out. Brilliant.
@@giovannistefanello6744 It said it was coded, and still someone mustve surely decided this should be coded. They mustve decide which phrases are interesting, fe. And they mustve checked how well the code worked. So, they mustve spent loads of time on it
What a treat! I loved it! Wouldn't have found the break-in without Simon pointing out the set, and it was a joy to follow along. Definitely worth another go in the future. Thank you!
This one was too hard for me to do on my own, so I'm trying to solve alongside Simon and the whole 16/49 pairs were driving me crazy because I couldn't figure out his logic. Felt so much better when that turned out to be in error.
I've just got to where he's done it. The mistake is thinking the 1 has to be accompanied by 6 when 7 & 8 are still available. Rather than tear my hair out I came to the comments to see if anyone else spotted it. Schadenfreude is great, knowing he didn't get jammy..... this time :)
If the thermo is 1234, then one whisper sees 123, needs a 49 but the other whisper would only see a 34. It could be 1 or 2. And vice versa for the other one 56:05 you can see right now. Look at the whispers. One whisper sees 789 and this has to be 6 with its monogamous 1. HOWEVER the other whisper sees 678 and this has to have a 9, but that DOESNT mean its neighbor needs to be a 4. This logic is also true of the 1234 variant.
@@MattOGormanSmithConsider yourself lucky ;) I watched this yesterday right after release just before going to bed, until the 1-6 incident. I kept asking why it cant be 1-7, tried looking at the comments but nothing yet. Eventually I got so frustrated with myself for not getting it that I had to close the video and go to sleep 😅 Lets just say that I would have slept way better if I had watched the video till the end.. 😝
Brilliant puzzle and great solve. Solved it in 103:06. At 48:04 it was really funny to see Simon put in the digits of the two thermos EXCEPT the very last digit, which would have given the two 4s in column 4. Instead later he notices the 3s in column 3 :)
Myxo...wow, wow and more wow!! I just can't fathom how you ended up setting this! Phenomenal solving from you Simon and equally brilliant smooth recovery after determining 4 was ruled out from R1.
Personal Time: 1h15m51s Very glad to see Simon made the same mistake that I did with the 4-9 pencilmarks, being stumped at the exact same moment in the solve!
The X-wing on 5s to rule it out of the yellow cells in columns 1 and 9 is I think unnecessary, from the set work alone it can be shown that there must be exactly one 5 in yellow (there definitely were no 5s in any of the cancelled cells on the whispers, so every 5 in the remaining purple must have a counterpart in yellow and vice versa, and you've got the one given 5 in purple and nowhere to place a second), so once you have the 15 pair in column 5 that's the sole yellow 5 accounted for...
I know, right. I yelled when he didn't complete the thermo in the top left, by placing 4 in r1c4. Why, just why? Who enters 1,2,3....and doesn't enter the 4! Simon, that's who. 😂 Edit: And I only realised later that the 3s he did enter were already clashing in column 3. Missed by both myself and Simon. (To be fair to me, I was anticipating the clash in c4 on 4s, since that's what I noticed during my solve, so I wasn't looking for any other clashes 🙂).
@@RichSmith77 You saved me a comment. Well, sort of. I was going to say the same thing but I think you said it better. So I'll just comment with "Ditto!"
The rules themselves are very standard now, but it feels so original as a puzzle because of the idea of matching high/low pairs out of the sets. Once you cotton on to that it is really a fun solve.
I thought this was going to be a puzzle with a horrendously hard break-in that just fell apart afterward, but the break-in was actually slightly less than horrendous and it remained quite tenacious to solve throughout.
41:53 - Doesn't that logic just ensure the 4-9, and then a 1-X? 1 isn't monogamous, so in the case of the thermo being low, the 1 would be on the bottom whisper line but could pair with any high (except for the 8, due to sudoku; and except for the 9 because of the 4… but 7 should still be valid)?
Around the 40:00 mark... I see that only 1 and 4 are left as low digits if the thermo contains 2,3. But why does the 1 have to be paired with a 6? It could just as well be a 7 no? Same logic applies when the thermo contains 7 and 8. The 1,6 pair is given. But the 9 could be paired with 2 or 3 as well
Me spotting one thing that Simon hasn’t spotted; “How can you not see that, it’s so blindingly obvious. Come on man!” Simon immediately seeing one hundred things I could stare at a puzzle for ten minutes and be none the wiser “Ah yes, I’d have seen that given another second or two.”
42:53, no, Simon, that didn't prove that 4 had to go with 9 if the digits were high on the thermo. All it does is prove the 1 and 9 on the lines in b19.
I finished in 137 minutes. This was one of those puzzles where I could see what the logic was going to be, but had a tough time proving it. I noticed that it was going to be balancing the parities of highs and lows along the edges. I finally started to prove it by looking the angled thermos and seeing which ones could possibly be high and low. I finally got to see that 4 on the end of the thermo always failed on both sides. That made r1c4 always a high. Somewhere a while before that, I had proved that a high end couldn't go with a low bulb, so that finally gave me enough information to progress and solve this thing. This was quite an enjoyable sudoku that had some wicked geometry. I wish I was better at visualization, because it feels weird having to write in some of the digits for me to concentrate on. I wasn't bifurcating it, but I did use it to see the parities. Thinking about it now, I guess I could have replaced those parities with colors and did it that way. Great Puzzle!
42:28 The logic about the 61 pair is correct, but concluding that the other pair then has to be 49 is wrong, no? It can be 39 or 29 right? Am I missing something? edit: nevermind
Cheers. I just reached this point and came to the comments. I guess I'll keep watching. (Fortunately it should break in box 9 eventually, forcing him to correct it, but it just happens to be correct in box 1).
When the set had fulfilled their duties, it helped me ro remove their colours and instead colour mark highs/lows. Made it visibly clearer when the highs and lows were fulfilled in a row or collum, which made the ending even more enjoyable
Simon: I'm still alive Me: quietly scraps my plans to send exactly 45 flowers bundled in bouquets of 9 to the funeral Glad you made it through, Simon! A very fun puzzle to watch!
35:02 I think I know. The bulb in box 4, if a 1, makes the bulb in box 2 a 5. If they are both 1, then we get 1234 on both thermos and the 2’s clash. HOWEVER. Due to the 15 pair in column 5, if box 4 bulb is a 1, box 2 bulb is a 5, then box 8 bulb is also a 1 and now the 4’s clash on the tips. So the bulb in box 4 can never be a 1 48:26 PLS PENCIL IN THE LAST DIGIT
31:30 I find it kinda funny that he gets a little excited about using an X-wing for the first time in a long time, because it's not even necessary. He's only got one five in purple and he's already got the matching yellow give in column 5. So he could remove 5 from all the other yellow cells.
11:32 Can someone why 5 and 8 being given means that they add 13 to the pink total and not the yellow total? We were told through set that the digits were equivalent so there is a 5 and 8 somewhere in yellow. The thermos I get. But not this particular point
I don't think Simon expressed it as clearly as he usually does, but what I think he's getting at is that, if the given digits were removed from purple and thermo bulbs and tips were removed from both purple and yellow, then you would have removed at least 13+12=25 more from purple than from yellow. So what's left would have at least 25 more in the remaining yellow cells than the remaining purple cells. But he doesn't use this, so it doesn't matter too much.
I meant to comment at the time of the video but I fell asleep listening to Simon (no criticism of Simon intended)!! Sensational puzzle Myxo. Delighted to have got through it at all but the sheer beauty and cleverness of the solve path made this one especially satisfying. Thanks for setting it. P.S. I actually tried to set a not too dissimilar looking puzzle, in terms of layout, last year (I was experimenting with region sum lines as opposed to thermometers) and given I had to accept defeat, I’m guessing this took a while to construct!!
Me: yay, there are gonna be two 3s in the corner! Simon: oh gosh, I've broken the puzzle. Me: sad noises. Me, later: ohhh, we still are gonna get two 3s in the corner, hurray :D
The xwing on 5s to remove them from yellow wasn't necessary to remove 5s from yellow. There was one given 5 in the purple set, no 5s on the whispers, and every other purple was either 489. So there is exactly one yellow 5 then, you knew it was in c5. This also meant that when you removed the intersecting cells from purple and yellow, two of those were 5s, r1 ruled out from the given 5, so one in r5, one in r9, and similar logic to put one in c1, one in c9.
42:25 I think you made a leap or mistake in logic. how did you conclude that in box 9 the bottom row whisper would be a 1-6 pair if the thermo had 2,3 on it ? I get why the 9-4 would be on the other and why 1 would be on that bottom whisper but couldn’t it pair with 7? 6 is monogamous but 1 is not so it doesn’t force the 6 does it?
At 42:30ish, I was screaming "Nooooo! That's not right!" and crossing my fingers that Simon wouldn't have gotten lucky. At 55:30ish, my moment of schadenfreude arrived.
Constraints combination is incredible! wow! Basic variants but used in a way never used before. Even before trying to place that in the grid so it works, how do you even get the sheer idea of that specific "constraint mix"? (ok, a bit unclear here, I'm just trying to avoid spoilers)
Getting enough high digits in the yellow boxes meant that at least 2 of the thermo bubbles would have to be a 6 (with 9s at the tip), and as there was a 6 in the centre, the 2 thermos had to be the ones on the side. Later the fact that I had to put 8s on the vertical lines in the centre column and on the on in column 9 forced the 8 in the top row resolving the 4/8 in the centre box.
On the mistake you made: You could've noted that in the 1-4 case you needed a 49 pair and a 1, in the 6-9 case you needed a 9 and a 16 pair. So after that deduction you could've pencilmarked the 1's and the 9's, but indeed pencilmarking the 4's and 6's was a mistake. Cool puzzle!
Haven't finished the video yet, but at around 53:00, what's stopping the thermos in the corner from being 1789? Since they only have to increase, I don't know why Simon reasoned that it would be 1234 or 6789, without the possibility of 1789. Edit: Just remembered, the geometry requires the bulb start and end to both be either low digits or high digits. Makes sense now!
I’m not following the logic at 42:25. Why does 1 have to go with 6 if the thermometer is low, and why does the 9 need to go with a 4 if the thermometer is high? Why couldn’t it be 1-7 or 2-9, for example? Maybe this is answered later in the video.
That was incredibly challenging for me, and took me 2:58:24 to do. I had to go about finding a bunch of things the hard way. I also had to restart, since I misunderstood the rules for about an hour.
1:02:32 “I haven’t spotted that” literally 5 or 10 minutes after Simon explained why if we put 6s on thermo bulbs both of the yellow digits would be 7s (because of sudoku) and why that’s ok that they don’t match with 7s in purple 😂
I would never have completed this puzzle without your deduction. When you say the clue is to maintain the number of high and low digits in purple and yellow, that's when I could go on by myself but I would NEVER come to that point by myself.
The only thing I don’t understand is why the side thermos had to be either 1234 or 6789. Obviously if the first digit was 6 the rest had to be 789. But Simon seems to ignore the possibilities of 1789, 1289, and 1239. Clearly those weren’t correct, but I don’t know why they were ruled out.
I got as far as setting up the SET theory, and I could see that there were high-low issues. But I tried all kinds of ways to make the arithmetic work, forcing a constraint, and I just couldn't. So I guessed that ultimately, there WAS a constraint that forced a certain condition on the thermos. From that point, it only took me a few wrong guesses over two or three days to solve the puzzle. So I was amazed and surprised to see the different way Simon used SET theory to come up with a very different type of constraint...which ended up being the same as mine, but who could have figured it?? Maybe it's not the way you're supposed to solve these, but it was still fun.
Another way to resolve the corner thermos is to notice that whichever center thermo is 1234, the 2 and 3 will hit BOTH corner thermos and force them to be 6789 (this is true either way round). edit: Also, the corner whispers could have been penciled in with 1's and 9's before resolving the thermos, but not any other digit.
At 47:50, why does Simon say does r8c5 becoming a 1 make r9c6 a 9? Is it because r6c9 couldn't be a 1, since then there would be nowhere for 1 in box 5, so r6c9 is 6, making r9c6 a 9. That would be a logical way to reach the conclusion, but Simon doesn't appear to explain it that way. In fact, he says r9c6 a 9 then makes r6c9 a 6, the exact opposite way round. Confusing. Edit: A pity he didn't either notice the two 3s in column 3 seconds later (48:07), or complete the top thermo and see 4s clashing on column 4. He could have saved 5 minutes.
Because the two thermos would clash on the digit next to 1. They would both be a 2 given that he had already deducted that the thermos had to be 1,2,3,4 to keep the low digits balance
@@gui789 Thanks. That could have been his reasoning. It just seemed a little odd that he said this being a 1 makes this a 9, which makes this a 6. Whereas it was more like, this being a 1 makes this a 6789 thermo. It made the other end a 6 as much as it made the near end a 9. It would have been clearer still had he said this being a 1 makes this (r7c4) a 2, makes this (r7c8) a 7, makes this a 6789 thermo. 👍
I tried the same SETT setting myself (finally for once I identified the useful sets to pitch against each other), but alas - I was trying to work out min/max of diff between the sums of the 2 colours, and that lead to a dead end. Alas - I will never be able to use SET independantly. I can never foresee what deduction would be useful with it :(((. The puzzle was brilliant, no doubt.
So many lovely deductions, still at 1:01:21 in Simon fills in the 2 and the 7 of the bottom 27 pair. Really round about way, because just before he removed the 9 possibility from r8c1 ... leaving it with a 67. But there's already a 6 in column one. So simple sudoku would suffice. Would suffice for us peasants, not Simon.
Greetings Simon. I love your videos and am a patron but I would like to know how to do the puzzle hunts on mobile. I usually do sudoku on my phone but I've been having trouble getting the rewards puzzles to be playable on my phone. Thanks for any help with this from you or your amazing fans.
I'm not sure if this works for all mobiles, but I've been playing them on my Android phone ok. You can download the PDF document attached to the Patreon post, open it on your phone, and -click- tap the underlined URL links in the document. It should open the puzzles in a web browser page just the same as the links under the UA-cam videos. They open in the same software (Sven's).
Can somebody please tell me why Simon is pronouncing "issue" with an s instead of the "sh"-sound? (at 27:38 in the video) As a non native speaker, I learned that issue is pronounced with the "sh"-sound. Is Simon speaking a dialect, or did I learn the wrong pronunciation? Thanks in advance!
This is an american vs british english variation, as are very many of small spelling or vowel sounds. On the internet, people will understand you either way.
He was looking at the cells on the thermos. The bulbs have to be at least 3 lower than the tips. Since all the bulbs are in yellow and the tips in purple, you get a difference of at least 4*3=12 in those cells. The other cells have to balance this difference so that both sets get to the same total. And some of that can be balanced by the empty cells and the given digits, but not all of it.
First observation, Simon is about to deduce via x-wing that no more fives are in yellow, but he could have seen that there was only 1x 5 in purple (because he marked all purple). (33 minute mark)
im so confused how he misses the 4. conflicting with each other. at 46:45 he says it doesnt work. i thought this is where he would notice that if the thermo on the left was low than it would would force a 4 in R1C5 and R4C5 if he makes the top middle thermo a 1 it the 2's would clash in R3C2 and R3C6. when it forces that thermo to be high is when it forces the 4 in R4C5 clashing with the 4 in R1C5. Instead of this Logic Simon negates it with the 3s in R2C3 and R6C3. clashing. LOL. at 48:14 even though he doesnt notice the 3s clashing. he stops finishing putting the 4 on the thermo which would have also clashed this the 4 in box 5. lol. im glad im not the only one who misses these things at times when solving puzzles. but i do it on a lot higher frequency of times. and it takes me a whole lot longer to figure out what i missed. its just funnier when seeing other people make the same kinds of mistakes.
@@HunterJE A collection of terms where there is no rule or pattern to determine the next term is not a sequence. In the same way that when we say "average" without any qualification it is taken to be "mean average", if we say "sequence" without any qualification then it is generally taken as "arithmetic sequence", where consecutive terms progress with equal steps.
@@stevieinselby No, "arithmetic sequence" means arithmetic sequence. We already have the modifier "increasing" right there in the rules to tell us the constraints on what kinds of arbitrary sequences can appear on the thermo clues.
I agree. That seemed to be a very specific rule that indicated strictly incremental increase. I came back to the video and saw that the rules here on the video are different so I assumed they edited it to make it clearer than the setter’s version. Turns out, though, that all the thermos did, in fact, increase 1234, 5678, and 6789

@@plum2584 You're not wrong. Simon was using the whispers lines incorrectly at this point. The correct application would have been that if the thermometer was low, then there was a 4-9 pair and a 1-X pair, if it was high there was a 1-6 pair and an X-9 pair. The 4 he gets because of this logic is dirty.
I am of the belief that we are living in a golden age of Sudoku, and that posterity study these creations as we do a work of art.

A very lovely puzzle! I've been watching these every day for a while and it's inspired me to get out one of my Sudoku books I got for Christmas as a kid. It's one of those big spiral-bound ones with 300+ puzzles ranging in difficulty, and when I flipped through it the other day I found that I'd already done the first 50 back in high school by the looks of my handwriting! I've started carrying on where I left off, but now I'm dating them when I finish so if it's another decade or so before I open this book again I can see when I worked on them. I'm delighted to report that (although it probably wasn't necessary to solve the puzzle, since this early in the book they still only really require you to see naked singles) I found an X-wing, and actually used it to find a digit! I've spotted X-wings before, but never knew how to use them to eliminate possibilities in other columns. Thanks so much for getting me back into Sudoku again, and encouraging me to finally learn the techniques I wanted to know as a kid!
33:00 - Unless I'm misunderstanding, you didn't need to do the X-Wing to know that there were no 5 in the yellow cells in C1 or C9. The relative scale of the purple and yellow digits were the same, meaning equal numbers of low digits, equal number of high digits and equal number of 5's.
The only 5 you had in purple was from the given 5 so once you figured out there had to be a 5 in a C5 yellow cell, then there couldn't be a 5 in any other yellow cell.
Your logic and the logic he used were both correct in eliminating the 5's from the other thermos. because no 5s could go on the german whispers. Simon just likes doing things the hard way because yours was alot quicker in eliminating the 5s
That's what I was thinking. But in the end both processes are valid
I saw it this way too. Since there are no pencil marked 5s in purple (and none on whispers) you know there is only one 5 in each purple and yellow so once you find the 5 in yellow (in the 1,5 pair), you can remove the other pencil marks for 5 in yellow.
But Simon never does anything the obvious way!
I did that the same way
I think what I loved most about this was the synergy of the clues. They all worked together throughout the solve and were always relevant, and you never needed to make guesses
What a great recovery! Loved that!
I have seen around 100 CtC videos and to me this is the most beautifull break in i have seen.
"A little known technique that I rarely explore in these puzzles known as sudoku" 😂😂😂
At the 40ish minute mark, you can prove that both top left and bottom right thermos must be 6-9. If you make either 1-4, it places a 4 in Box 5, but that results in a clash of 2s in R3 or R7.
I came here to say this. But then Simon failed later to spot 2 4s in column 4 and instead ruled out his hypothesis by spotting 2 3s which he hadn't yet put into column 3! But I wish I was half as clever as he is!
Was hard to watch Simon doggedly avoid seeing this simple path.
1:11:33 Could We Do Better With A Digit Like Six will be an excellent song title when you get around to making Cracking The Cryptic: The Musical.
Could we do better with a digit like six?
Is it the right tool in our arsenal of tricks
to help us bounce back from the punches and kicks;
oh could we do better with a digit like six?
Yes could we do better with a digit like six?
Will it be the figure that finally sticks
from our possible pot-luck of nine number picks?
Perhaps we'll do better with a digit like six...
And if we do better with a digit like six,
will we find the logic all suddenly clicks
and speed through the cells we have still yet to fix?
Let's hope we'll do better with a digit like six.
So could we do better with a digit like six-o,
and prove ourselves to that maleficent Phisto
by cracking this cryptic conundrum from Myxo;
oh could we do better with a digit like six-o?
Hmmm: Cracking The Cryptic: The Musical -- I like it. Simon would be a tenor, Mark a baritone. Do we bring in famous setters as other characters, and to get some higher voices? Is Jay Dyer a soprano, for example? We need a chorus of dancing digits, naturally, and of course a great big airplane, audible throughout and finally becoming visible at the start of the big number mid-way through Act 2. 😸
I saw quickly how to make the sets, I saw what it did with the thermometers. I saw how the thermometers looked at each other to make the central 2 thermometers different from either of the outer ones. I just could not wrap my head around how tobuse all this insight to break open the puzzle. I stared at the grid for 2 hours across 3 days, but just didnt get the logic straight. Then i watched the video. Thinking about low and high digits definitely was the key that I never figured out. Brilliant.

What a treat! I loved it! Wouldn't have found the break-in without Simon pointing out the set, and it was a joy to follow along. Definitely worth another go in the future. Thank you!
This one was too hard for me to do on my own, so I'm trying to solve alongside Simon and the whole 16/49 pairs were driving me crazy because I couldn't figure out his logic. Felt so much better when that turned out to be in error.
One of the all time greatest puzzles!
Cosmic-class‼
I spent a lot of the video confused by the 16 49 pencil-marking, I'm almost happy it broke because I had no idea what I was missing.
I've just got to where he's done it. The mistake is thinking the 1 has to be accompanied by 6 when 7 & 8 are still available. Rather than tear my hair out I came to the comments to see if anyone else spotted it. Schadenfreude is great, knowing he didn't get jammy..... this time :)
If the thermo is 1234, then one whisper sees 123, needs a 49 but the other whisper would only see a 34. It could be 1 or 2. And vice versa for the other one
56:05 you can see right now. Look at the whispers. One whisper sees 789 and this has to be 6 with its monogamous 1. HOWEVER the other whisper sees 678 and this has to have a 9, but that DOESNT mean its neighbor needs to be a 4. This logic is also true of the 1234 variant.
Me too!!!
I couldn’t see it either. Thanks for the comment
@@MattOGormanSmithConsider yourself lucky ;) I watched this yesterday right after release just before going to bed, until the 1-6 incident. I kept asking why it cant be 1-7, tried looking at the comments but nothing yet. Eventually I got so frustrated with myself for not getting it that I had to close the video and go to sleep 😅 Lets just say that I would have slept way better if I had watched the video till the end.. 😝
Brilliant puzzle and great solve. Solved it in 103:06. At 48:04 it was really funny to see Simon put in the digits of the two thermos EXCEPT the very last digit, which would have given the two 4s in column 4. Instead later he notices the 3s in column 3 :)
Myxo...wow, wow and more wow!! I just can't fathom how you ended up setting this! Phenomenal solving from you Simon and equally brilliant smooth recovery after determining 4 was ruled out from R1.
Personal Time: 1h15m51s
Very glad to see Simon made the same mistake that I did with the 4-9 pencilmarks, being stumped at the exact same moment in the solve!
The X-wing on 5s to rule it out of the yellow cells in columns 1 and 9 is I think unnecessary, from the set work alone it can be shown that there must be exactly one 5 in yellow (there definitely were no 5s in any of the cancelled cells on the whispers, so every 5 in the remaining purple must have a counterpart in yellow and vice versa, and you've got the one given 5 in purple and nowhere to place a second), so once you have the 15 pair in column 5 that's the sole yellow 5 accounted for...
At 48:38 he was literally a second away from realising that column 4 is broken 😢. A brilliant solve nonetheless
I know, right.
I yelled when he didn't complete the thermo in the top left, by placing 4 in r1c4. Why, just why? Who enters 1,2,3....and doesn't enter the 4!
Simon, that's who. 😂
Edit: And I only realised later that the 3s he did enter were already clashing in column 3. Missed by both myself and Simon. (To be fair to me, I was anticipating the clash in c4 on 4s, since that's what I noticed during my solve, so I wasn't looking for any other clashes 🙂).
@@RichSmith77 You saved me a comment. Well, sort of. I was going to say the same thing but I think you said it better. So I'll just comment with "Ditto!"
Simon doesn’t even mess up like normal people.
The rules themselves are very standard now, but it feels so original as a puzzle because of the idea of matching high/low pairs out of the sets. Once you cotton on to that it is really a fun solve.
I thought this was going to be a puzzle with a horrendously hard break-in that just fell apart afterward, but the break-in was actually slightly less than horrendous and it remained quite tenacious to solve throughout.
Simon's biggest enemy in a sudoku puzzle is sudoku
omg this is the first time i've already solved a puzzle you featured. don't know why it made me so happy lol.
41:53 - Doesn't that logic just ensure the 4-9, and then a 1-X? 1 isn't monogamous, so in the case of the thermo being low, the 1 would be on the bottom whisper line but could pair with any high (except for the 8, due to sudoku; and except for the 9 because of the 4… but 7 should still be valid)?
He realizes that later in the video, skip to 57:44
I have the same question I see one case is 49 1x and the other 16 x9. At that point, you can only mark a 1x x9
I should have waited until 57:15…
Great to see Simon recover. That's when I just close the window and go watch the video.
Whew! That's why I ran to the comments.
That grid just looks bananas 😳
Around the 40:00 mark... I see that only 1 and 4 are left as low digits if the thermo contains 2,3. But why does the 1 have to be paired with a 6? It could just as well be a 7 no? Same logic applies when the thermo contains 7 and 8. The 1,6 pair is given. But the 9 could be paired with 2 or 3 as well
Me spotting one thing that Simon hasn’t spotted;
“How can you not see that, it’s so blindingly obvious. Come on man!”
Simon immediately seeing one hundred things I could stare at a puzzle for ten minutes and be none the wiser “Ah yes, I’d have seen that given another second or two.”
Once it is established, that one of the center-thermos ends with 4, neither of the sidethermos can, as the 2s on those thermos would clash.
42:53, no, Simon, that didn't prove that 4 had to go with 9 if the digits were high on the thermo. All it does is prove the 1 and 9 on the lines in b19.
I noticed this too. It's an easy mistake to make (4 on the line implies 9, but not vice versa)
He unwinds it later though
Watching these central thermos not being updated for sooooooo long is a real torture ;-)
I finished in 137 minutes. This was one of those puzzles where I could see what the logic was going to be, but had a tough time proving it. I noticed that it was going to be balancing the parities of highs and lows along the edges. I finally started to prove it by looking the angled thermos and seeing which ones could possibly be high and low. I finally got to see that 4 on the end of the thermo always failed on both sides. That made r1c4 always a high. Somewhere a while before that, I had proved that a high end couldn't go with a low bulb, so that finally gave me enough information to progress and solve this thing. This was quite an enjoyable sudoku that had some wicked geometry. I wish I was better at visualization, because it feels weird having to write in some of the digits for me to concentrate on. I wasn't bifurcating it, but I did use it to see the parities. Thinking about it now, I guess I could have replaced those parities with colors and did it that way. Great Puzzle!
how in the world do people set things like this?? total genius!
42:28 The logic about the 61 pair is correct, but concluding that the other pair then has to be 49 is wrong, no? It can be 39 or 29 right? Am I missing something?
edit: nevermind
Yes, you are missing later in the video when he realises his mistake 🙂
@@SomeRandomGuyOnUA-cam My bad I just saw it.
Cheers. I just reached this point and came to the comments. I guess I'll keep watching. (Fortunately it should break in box 9 eventually, forcing him to correct it, but it just happens to be correct in box 1).
Nice to know this can be solved by sudokuing and playing w 54.
The push/pull ebb/flow of the design is neat
I had to watch 7 minutes to get the break in hint, but then finished in 31 mins. Great puzzle!
Congrat. For me, I had to think for only 22min, before I gave up and decided to watch master Simon solving it in a clever way ^_^
When the set had fulfilled their duties, it helped me ro remove their colours and instead colour mark highs/lows. Made it visibly clearer when the highs and lows were fulfilled in a row or collum, which made the ending even more enjoyable
Simon: I'm still alive
Me: quietly scraps my plans to send exactly 45 flowers bundled in bouquets of 9 to the funeral
Glad you made it through, Simon! A very fun puzzle to watch!
I was trying to make a joke about The Secret but I think math failed me, whoops carry on
Amazing puzzle and equally amazing solve!
Amazing puzzle!
35:02 I think I know. The bulb in box 4, if a 1, makes the bulb in box 2 a 5. If they are both 1, then we get 1234 on both thermos and the 2’s clash. HOWEVER. Due to the 15 pair in column 5, if box 4 bulb is a 1, box 2 bulb is a 5, then box 8 bulb is also a 1 and now the 4’s clash on the tips. So the bulb in box 4 can never be a 1
48:26 PLS PENCIL IN THE LAST DIGIT
31:30 I find it kinda funny that he gets a little excited about using an X-wing for the first time in a long time, because it's not even necessary. He's only got one five in purple and he's already got the matching yellow give in column 5. So he could remove 5 from all the other yellow cells.
11:32 Can someone why 5 and 8 being given means that they add 13 to the pink total and not the yellow total? We were told through set that the digits were equivalent so there is a 5 and 8 somewhere in yellow. The thermos I get. But not this particular point
I don't think Simon expressed it as clearly as he usually does, but what I think he's getting at is that, if the given digits were removed from purple and thermo bulbs and tips were removed from both purple and yellow, then you would have removed at least 13+12=25 more from purple than from yellow. So what's left would have at least 25 more in the remaining yellow cells than the remaining purple cells.
But he doesn't use this, so it doesn't matter too much.
I meant to comment at the time of the video but I fell asleep listening to Simon (no criticism of Simon intended)!! Sensational puzzle Myxo. Delighted to have got through it at all but the sheer beauty and cleverness of the solve path made this one especially satisfying. Thanks for setting it.
P.S. I actually tried to set a not too dissimilar looking puzzle, in terms of layout, last year (I was experimenting with region sum lines as opposed to thermometers) and given I had to accept defeat, I’m guessing this took a while to construct!!
Me: yay, there are gonna be two 3s in the corner!
Simon: oh gosh, I've broken the puzzle.
Me: sad noises.
Me, later: ohhh, we still are gonna get two 3s in the corner, hurray :D
The sudoku after the initial break-in was still not trivial. Delightful.
Nice job Simon.
The xwing on 5s to remove them from yellow wasn't necessary to remove 5s from yellow. There was one given 5 in the purple set, no 5s on the whispers, and every other purple was either 489. So there is exactly one yellow 5 then, you knew it was in c5. This also meant that when you removed the intersecting cells from purple and yellow, two of those were 5s, r1 ruled out from the given 5, so one in r5, one in r9, and similar logic to put one in c1, one in c9.
42:25 I think you made a leap or mistake in logic. how did you conclude that in box 9 the bottom row whisper would be a 1-6 pair if the thermo had 2,3 on it ? I get why the 9-4 would be on the other and why 1 would be on that bottom whisper but couldn’t it pair with 7? 6 is monogamous but 1 is not so it doesn’t force the 6 does it?
At 42:30ish, I was screaming "Nooooo! That's not right!" and crossing my fingers that Simon wouldn't have gotten lucky. At 55:30ish, my moment of schadenfreude arrived.
Constraints combination is incredible! wow! Basic variants but used in a way never used before. Even before trying to place that in the grid so it works, how do you even get the sheer idea of that specific "constraint mix"? (ok, a bit unclear here, I'm just trying to avoid spoilers)
Getting enough high digits in the yellow boxes meant that at least 2 of the thermo bubbles would have to be a 6 (with 9s at the tip), and as there was a 6 in the centre, the 2 thermos had to be the ones on the side.
Later the fact that I had to put 8s on the vertical lines in the centre column and on the on in column 9 forced the 8 in the top row resolving the 4/8 in the centre box.
The first time in 5+ years I've beaten Simon's time. So chuffed!!
👏👏👏👏👏👏👏
Very exciting puzzle.
Kind of surprised you didn't use the big x-wing of 3s in the corners earlier
*places 8 digits in grid* "Now, has that done anything for us?"
On the mistake you made: You could've noted that in the 1-4 case you needed a 49 pair and a 1, in the 6-9 case you needed a 9 and a 16 pair. So after that deduction you could've pencilmarked the 1's and the 9's, but indeed pencilmarking the 4's and 6's was a mistake. Cool puzzle!
14:38 for me. Well, that might be one of my best solves ever. Fantastic puzzle, loved it!!
Congratulations. It's a good day for me too when I'm only 3x your solve time.
Haven't finished the video yet, but at around 53:00, what's stopping the thermos in the corner from being 1789? Since they only have to increase, I don't know why Simon reasoned that it would be 1234 or 6789, without the possibility of 1789.
Edit: Just remembered, the geometry requires the bulb start and end to both be either low digits or high digits. Makes sense now!
I’m not following the logic at 42:25. Why does 1 have to go with 6 if the thermometer is low, and why does the 9 need to go with a 4 if the thermometer is high? Why couldn’t it be 1-7 or 2-9, for example? Maybe this is answered later in the video.
Ahh, I wasn’t confused. I see he found it.
That was incredibly challenging for me, and took me 2:58:24 to do. I had to go about finding a bunch of things the hard way. I also had to restart, since I misunderstood the rules for about an hour.
1:02:32 “I haven’t spotted that” literally 5 or 10 minutes after Simon explained why if we put 6s on thermo bulbs both of the yellow digits would be 7s (because of sudoku) and why that’s ok that they don’t match with 7s in purple 😂
I would never have completed this puzzle without your deduction. When you say the clue is to maintain the number of high and low digits in purple and yellow, that's when I could go on by myself but I would NEVER come to that point by myself.
The only thing I don’t understand is why the side thermos had to be either 1234 or 6789. Obviously if the first digit was 6 the rest had to be 789. But Simon seems to ignore the possibilities of 1789, 1289, and 1239. Clearly those weren’t correct, but I don’t know why they were ruled out.
If the thermos starts with a low number it has to stay a low number. If not purple will have too many high numbers for yellow to even out
"Elegant way to finish it" (at 1:13:00) is to realise (and possibly sing) that's an X-wing 3 in the corners
A bit late to it this evening - but this is a brilliant puzzle and glad to see it featured.
I got as far as setting up the SET theory, and I could see that there were high-low issues. But I tried all kinds of ways to make the arithmetic work, forcing a constraint, and I just couldn't. So I guessed that ultimately, there WAS a constraint that forced a certain condition on the thermos. From that point, it only took me a few wrong guesses over two or three days to solve the puzzle. So I was amazed and surprised to see the different way Simon used SET theory to come up with a very different type of constraint...which ended up being the same as mine, but who could have figured it?? Maybe it's not the way you're supposed to solve these, but it was still fun.
1:13 an elegant and clever way ? Sudoku of course !
28:25 for me. Interesting puzzle of highs and lows :) Gonna see if Simon solved it the same way.
Another way to resolve the corner thermos is to notice that whichever center thermo is 1234, the 2 and 3 will hit BOTH corner thermos and force them to be 6789 (this is true either way round).
edit: Also, the corner whispers could have been penciled in with 1's and 9's before resolving the thermos, but not any other digit.
At 47:50, why does Simon say does r8c5 becoming a 1 make r9c6 a 9?
Is it because r6c9 couldn't be a 1, since then there would be nowhere for 1 in box 5, so r6c9 is 6, making r9c6 a 9. That would be a logical way to reach the conclusion, but Simon doesn't appear to explain it that way. In fact, he says r9c6 a 9 then makes r6c9 a 6, the exact opposite way round. Confusing.
Edit: A pity he didn't either notice the two 3s in column 3 seconds later (48:07), or complete the top thermo and see 4s clashing on column 4. He could have saved 5 minutes.
Because the two thermos would clash on the digit next to 1. They would both be a 2 given that he had already deducted that the thermos had to be 1,2,3,4 to keep the low digits balance
@@gui789 Thanks. That could have been his reasoning.
It just seemed a little odd that he said this being a 1 makes this a 9, which makes this a 6. Whereas it was more like, this being a 1 makes this a 6789 thermo. It made the other end a 6 as much as it made the near end a 9. It would have been clearer still had he said this being a 1 makes this (r7c4) a 2, makes this (r7c8) a 7, makes this a 6789 thermo. 👍
I tried the same SETT setting myself (finally for once I identified the useful sets to pitch against each other), but alas - I was trying to work out min/max of diff between the sums of the 2 colours, and that lead to a dead end. Alas - I will never be able to use SET independantly. I can never foresee what deduction would be useful with it :(((. The puzzle was brilliant, no doubt.
10/10 puzzle
Fine Puzzle. Though I think Phistomefel might have recommended it for the two 3's in the Corner
So many lovely deductions, still at 1:01:21 in Simon fills in the 2 and the 7 of the bottom 27 pair. Really round about way, because just before he removed the 9 possibility from r8c1 ... leaving it with a 67. But there's already a 6 in column one. So simple sudoku would suffice. Would suffice for us peasants, not Simon.
Greetings Simon. I love your videos and am a patron but I would like to know how to do the puzzle hunts on mobile. I usually do sudoku on my phone but I've been having trouble getting the rewards puzzles to be playable on my phone. Thanks for any help with this from you or your amazing fans.
I'm not sure if this works for all mobiles, but I've been playing them on my Android phone ok. You can download the PDF document attached to the Patreon post, open it on your phone, and -click- tap the underlined URL links in the document. It should open the puzzles in a web browser page just the same as the links under the UA-cam videos. They open in the same software (Sven's).
I just checked this month's, and the links in the document don't look like URLs, but are links to "SudokuPad" (blue, underlined).
Can somebody please tell me why Simon is pronouncing "issue" with an s instead of the "sh"-sound? (at 27:38 in the video) As a non native speaker, I learned that issue is pronounced with the "sh"-sound. Is Simon speaking a dialect, or did I learn the wrong pronunciation? Thanks in advance!
I believe the regional accent that says issue and tissue without the "sh" sound is called received pronunciation, or RP.
This is an american vs british english variation, as are very many of small spelling or vowel sounds. On the internet, people will understand you either way.
@@Exuno5912 It's regional, not US vs UK. I use the "sh" sound for both issue and tissue. For context, I'm from Cambridgeshire.
Yeah, definitely not UK vs US - I'm from the North West in the UK, would never say issue without the 'sh' sound.
11:10 According to Set theory, shouldn't Yellow and Purple be comprised of the exact same digits? Then how is Purple 12 greater than Yellow?
Simon is talking about the purple and yellow cells on thermometers here, not all of them
He was looking at the cells on the thermos. The bulbs have to be at least 3 lower than the tips. Since all the bulbs are in yellow and the tips in purple, you get a difference of at least 4*3=12 in those cells. The other cells have to balance this difference so that both sets get to the same total. And some of that can be balanced by the empty cells and the given digits, but not all of it.
Scojojobo sounds like he has a problem with the power puff girls
This was fascinating for me. Just out of my reach. I could see all of the considerations, just couldn't juggle the interactions to make it work.
Took me a LOT of time. 09:32:07
I cheated a bit, until you introduced set idea, after that it solved without much of a problem
First observation, Simon is about to deduce via x-wing that no more fives are in yellow, but he could have seen that there was only 1x 5 in purple (because he marked all purple). (33 minute mark)
Saw the impending doom at 56 minutes. Forcing a 9 on a whisper does not mean its a 49 pair.
im so confused how he misses the 4. conflicting with each other. at 46:45 he says it doesnt work. i thought this is where he would notice that if the thermo on the left was low than it would would force a 4 in R1C5 and R4C5 if he makes the top middle thermo a 1 it the 2's would clash in R3C2 and R3C6. when it forces that thermo to be high is when it forces the 4 in R4C5 clashing with the 4 in R1C5. Instead of this Logic Simon negates it with the 3s in R2C3 and R6C3. clashing. LOL. at 48:14 even though he doesnt notice the 3s clashing. he stops finishing putting the 4 on the thermo which would have also clashed this the 4 in box 5. lol.
im glad im not the only one who misses these things at times when solving puzzles. but i do it on a lot higher frequency of times. and it takes me a whole lot longer to figure out what i missed. its just funnier when seeing other people make the same kinds of mistakes.
Nice 😉 ! And then fale by filling the 9 digit in when you have already 8 😁🤔
59:35 for the first digit
How many noncongruent solutions could there be without some of the givens...
One of the rules is: you can't put two 3s in one column 😆.
the rules officially read "thermometers form a increasing sequence in order..." I read that as each digit must increase by 1.. ie 4567. or 1234.
It doesn’t say “consecutive” but does say “sequence”. I take that to mean something like 2468 would also work
I mean mathematically speaking a "sequence" is just a collection of terms in an order...
@@HunterJE A collection of terms where there is no rule or pattern to determine the next term is not a sequence. In the same way that when we say "average" without any qualification it is taken to be "mean average", if we say "sequence" without any qualification then it is generally taken as "arithmetic sequence", where consecutive terms progress with equal steps.
@@stevieinselby No, "arithmetic sequence" means arithmetic sequence. We already have the modifier "increasing" right there in the rules to tell us the constraints on what kinds of arbitrary sequences can appear on the thermo clues.
I agree. That seemed to be a very specific rule that indicated strictly incremental increase. I came back to the video and saw that the rules here on the video are different so I assumed they edited it to make it clearer than the setter’s version. Turns out, though, that all the thermos did, in fact, increase 1234, 5678, and 6789
I'll be happy if I never see another SET puzzle for as long as I live.
only took me 55 min to do, i caught the logic of low and high digits faster i guess
Did anyone else have an advert every 5mins?
