Simon is a genius (There, I've said it). To be able to find the solution path, visualise the combinations in his mind, and explain it verbally in a 'live' setting as he discovers it, is nothing short of amazing. A true showcase of his talents.

@WereDictionary 18 дней назад

I'd liike to reinforce this. Simon tends to lowball his abilities but this is yet another really inpressive showcase of his puzzle-solving prowess.

@Paolo_De_Leva 18 дней назад

Totally true, but too lazy to notate on screen the combinations he can see in his mind. I am sure this would attract more viewers. He could show an *Excel* or *Notepad* window in the top-right part of the screen if he temporarily removed the rules from there. I believe the rules are overimposed in post-production, and the aide memoire can be added this way as well, or just compiled during the video recording. Anyway, it is definitely impressive that he was able to do that so skillfully without an *aide memoire.* I used a separate grid for that purpose, although I do not think it was strictly necessary in this case. Also, I liked a lot the use of *A-B-C* and *X-Y-Z* to explain some key initial deductions, without interfering with the existing colour code.

This puzzle is so far above my skill level that it's almost painful. You know it's tough when I can't follow your logic. Cracking solve of a very clever puzzle.

@pixllo 19 дней назад

To be fair, Simon did make it more complicated than it needed to be by going hyper theoretical. But if you're not that agile with weird or new logic, or new to Sudoku, it's perfectly understandable. It's funny how he can not only grasp but explain excessively convoluted stuff very clearly and simply, but obscure concepts half as hard he often obfuscates even more 😂. The ruleset is the big clue that should tell you where you need to focus: There are 34 cells in cages, and 4 sets of cages with distinct numbers. You need at least 2 of those sets to have all the 9 digits, because you could not fill it all otherwise. But that sums to 45 so the sum of those two sets divides 45, those sums can only be 9 and 15. Then you have 16 more cells to fill. If there were another 1 to 9 set, it would sum to something that can divide 45 but we've exhausted our options, so both other sets use 8 digits. So far we know the 9-sum set uses 5 cages (45/9), the 15-sum set uses 3 cages (45/15). The other sets use 6 cages altogether. Given the cages and their sizes, the 9-sum set can only be a single 9, and 4 couples, which gets you to the 25:18. (This set is colored dark green). Then you can infer that blue is the 15-sum set. (It's already using 7 cells and you need to add at least two). Then the r7-9c6 cage has to be either yellow or purple, but if it is yellow, yellow already uses 7 digits and needs one more cage, but yellow only uses 8 digits, it doesn't work so it's purple. The neat trick is to then notice that those 3 purple digits fit in a very specific place in box 5, and the 2 of the 3 digits in box 5's purple cage fit in one cage in box 3. That cage can't be green (touching), purple (already used those digits), blue (it would add to 15 but purple is now 3 cages so it can't add to more than 44/3=14.666) so it's yellow. It also means that yellow adds up to less than purple, and this forces a 9 to be somewhere in purple. Also, both yellow and purple are now 3 cages sets, so their sum is constrained. R3c6-7 can't be purple (its digit is the extra digit from box 5 purple cage), blue (touching) or yellow (touching) so it's green. R2C7-8 can't be green (touching), yellow (touching), nor blue (it would add to 15 without a 9 so 7+8, but then r3c7 could not be 7 or 8. While yellow and purple add to between 12 and 14, and the difference being the digit in r3c6 (so 1 or 2). Yet that cage is green but could not add to 9 anymore. So it's purple. It gets more straigtforward from that point on. I don't know if this helped, but I could not leave you missing out on how magic this puzzle was, I usually love the puzzles here but this is one of the few times I've felt in awe. Especially since it needed some thought but with some logic you could get there one step at a time. What an incredible setup by Jay Dyer.

@okmarshall 19 дней назад

@@pixllo thank you for your explanation. I had to read it a few times but this in conjunction with the video definitely helps get me closer.

That was an immaculate solve of a truly great puzzle. Simon, you don't always appreciate how good you are to see all those things first time on camera. Favourite moments "I'm being slow" at 30:15ish - not slow on my metric: and 46:25ff "what would make my day, if this becomes straightforward" when there are unresolved cages and you ought know that means there is one last trick up Jay's sleeve - which was duly spotted and negotiated more smoothly than I did it.

@emilywilliams3237 19 дней назад

Simon, you are also a genius. I was thinking about how one would go about this puzzle, and never would in a million years have figured out what you figured out about the number of totals that used all 9 digits in cages vs the number of totals that used only 8 of the 9 ... and all that flowed from that was just beautiful. What a puzzle - so glad to see another one by Jay Dyer on the channel! and what a solve - thank you.

Coloring the various cages and counting the number of cells led me to 34, so a variation of only two values from the max led me to putting 9 in the singular cell.

@TheBaabKaare 19 дней назад

31:00 A quicker way to figure out how the two 8 digit sets are divided is to ask how to fit 8 digits into only 2 cages when there are no cages with more than 4 digits. And the answer to that is to put them in two 4 digit cages. But since the only two 4 digit cages in the puzzle are touching, that is also not possible, and therefore there two sets have to have 3 cages each to fit all their digits.

You do all the deduction more piecemeal than I could, I had to write out the values of cages and deduce the potential combinations of cage sizes that fit them. Doing that I deduced that only 14 was able to have a 2,3,3 combo of cage sizes, and the only values left were 13,12 for the 2,2,4 combo of cage sizes, which broke it open for me. All in all I was probably just scribbling for half an hour. The combos are surprisingly limited though, and I knew the kinds of sets I was looking for inside the cages at that point, which quickly started forcing them. I also did the ABC to determine the [redacted], which opened a lot up, after that the deductions of the individual 2 cages were nice but hard for me to see at times.

@willfancher9775 18 дней назад

You could have figured out that colors with 8 cells each needed to have 3 cages each much earlier. If it was 2 and 4 instead, then that implies one of the colors has two cages of size 4 (since there are no cages larger than 4 cells). But the only two cages with 4 cells are touching each other and can't be the same color.

Can someone explain to me how Simon reached the conclusion at 26:59 that the three rightmost cells in box 2 had to be digits ABC? Why could those digits not have gone into the three uncaged spaces in that box? Or into green or blue, for that matter? I missed that logical step.

By asking where the digits ABC of box 5 go in column 6. The purple ABCs in box 5 cannot be the same as the purples in box 8, so they can't go there. They obviously can't go in box 5, so it has to be box 2, column 6

Even when I am able to complete the puzzle, it still blows my mind how Simon does everything in his head where I have an Excel page full of numbers.

As a visual thinker, I still found it hard to understand the explainer! Maybe I should have seen the excel ;)

Sometimes it just takes going to sleep. I struggled and struggled with this for far longer than I care to admit. I did see all the logic in the end, and it was beautiful. The key piece I was missing was the way to rule one of the options out of the three-cell cage at the bottom. I sadly did end up just picking one and it was the right one, so I went back and had a look, but after another two hours and the start of a headache, I went to sleep. When I woke up, it only took ten more minutes to spot the problem. Spoiler warning: At this point in the puzzle I had one set of cages isolated to include a three-cell and a four-cell. If I made the other three-cell go along with the other four-cell, then there would be at least 7 different digits in each adding to a minimum of 28. This divided by two gives 14 for the sum, but if they took a two-cell region, then they would have all nine digits in three cages giving a total sum of 45 divided by 3 to get a sum of 15. That means that the possibility of both taking a two-cell region isn't possible as that would give both the same sum. One must take and one must not take with one being 14 and one being 15. This creates a problem, though, as that means the two missing digits from the four sets of 1 to 9 are missing from one of these two sets and the three-cell cage in the middle would have to take three two-cell cages (3+2+2+2=9 digits) to not be missing any, but that makes the total 45. Here's a little secret, 45 isn't evenly divisible by 4...which rules out this whole scenario of there being two sets with a four-cell and a three-cell cage. From there the one I had picked the night before was the only option and the rest of my logic being sound, I finished the puzzle, and thus rest my case, my brain, and now to enjoy seeing CtC solve this in spectacular and unimpeded fashion. I humbly bow to their incredible abilities. Thanks again for another wonderful puzzle, and as I'm sure it will be, just as amazing solution video.

So glad my logic was basically the same, even though it took me more than five times as long. Thank goodness it was the weekend. I liked how you were able to throw math around in your head so easily to figure out that it required two sets of 8 digits. I had to work the long way around to rule it out (explained mostly in my first comment, just missing a few earlier deductions that you use in the video). Even doing the sums as quick as you do, lol. I still have to use a killer cage sum cheat sheet/program, although the more I do it, I am getting certain intuitions that are more quickly proven. Can I just say, it is a wonderful thing seeing these videos and being able to solve these puzzles. To you and many others, it may seem like simple fun, but doing these regularly really does improve basic math skills. Thanks for all the entertainment and learning!

Unfortunately, without notes on the screen, just couldn't follow the cages/digits/34/etc reasoning that made up the bulk of the break-in.

I don't understand it at all😟

@bobblebardsley 19 дней назад

My cut-off for attempting the puzzle is about 20-30 minutes, although I do sometimes try to spot the break-in on longer videos. I'm slowly improving at variant sudoku but I don't yet have a hope of solving anything that produces an hour-long video on this channel 🤣

Well, 9 * 4 = 36, and there are 34 caged cells... so either there's 3 colors of 9 cells and 1 of 7, or there's 2 of 9 and 2 of 8. I can see that all 4 colors are represented in the group of cages around the shared borders of boxes 1 2 4 and 5. Neither 4 cage sum can be in the 1 cage, and the three cages along the border of boxes 2 and 3 must have different sums. I'm stuck there. My eyes keep drifting to the vertical 3 cage in box 8, column 6 - if it shares a color with the j cage in box 5, then there are only 3 cells in box 5 where the 3 candidates for the col 6 3 cage can go. There's something strange going on with the combinations but I'm not sure what angle to attack it from.. Hmm... I think... I think it has to be 2 of 9 and 2 of 8. Reasoning: at least two of the sums have to utilize all 9 digits 1-9 IE: They must be divisors of 45. 1, 3, 5, 9, 15, and 45. You can't use permutations of all 9 digits 1-9 to make sums of 1, 3, 5, and there isn't a 9 cage, so 45 isn't a candidate either. That means only 9 and 15 are viable sums for colors which use all 9 digits. There's no way to have 3 divisors of 45 represented among the 4 sums... ... I think. what's more : The only way to utilize the digit 9 in a cage which sums to 9... is with a 1-cage. Which means R2C5 is a 9. O_O

Conjunction Junction was part of a series of animations that taught various concepts. So I assume the title is a play on that. And you have to use disjointing to solve?

I have been watching for a couple months now and this is the first time i am totally lost in the beginning. I get the basic gist, but i can't follow along as you talk it through, which i usually can.

@angec9908 19 дней назад

Simon calls this puzzle “beautiful.” I call it “diabolical” because even with all of his explanations, I still don’t understand how he got there.

It could even be "That's very interesting..... No jokes!" - And I would tell you right now to respectfully close your mouth, CTC, and take my money.

I think the most unique thing about this channel. 52:15 he highlights 2 69's and giggles. But what he was really giggling at was being able to put 3 in the corner.

Why can't yellow have 4+3+2 cage sum up to 15 each? 26:50

@RichSmith77 19 дней назад

Earlier, from around 25:15, he worked out blue was the other colour that used all 9 digits, and therefore was the colour that summed to 15. Yellow couldn't also sum to 15. It had to be one of the two colours with 8 digits only.

Genius indeed, it is beyond me how one gets the idea, constructs that idea and make it into a puzzle with so little grid furniture, that Simon and many others, but certainly not me, can solve.
