** TODAY'S PUZZLE **
We have featured many puzzles by the maths professor Dorlir and today it is his daughter's 7th birthday! He has made a special miracle sudoku to celebrate so we thought it would be a nice puzzle to have a go at in today's video. This is an astonishing piece of work (how did he have the idea??!) and, although not easy, showcases some stunning logic. Bravo Dorlir and a very happy birthday to your daughter!
Play the puzzle at the link below:
sudokupad.app/zos75s0s5z
Rules:
Fill the grid with eight non-overlapping 2x4 regions oriented horizontally (i.e. 2 rows and 4 columns), such that each region contains the digits from 1 to 8 once each and no digit repeats in any row or column. Cells outside regions don't contain digits. Draw a single one-cell-wide loop in the grid that travels orthogonally, doesn't branch, and isn't allowed to touch itself, not even diagonally, and doesn't pass through any of the empty cells. Any two adjacent cells along this loop must include one extreme digit [1,2,7,8] and one medium digit [3,4,5,6]. For each region N, the digit N must be on the loop within this region. (Regions are numbered in reading order, based on the position of their top left cell, i.e. a region with its top left cell further down in the grid than another region will have the higher region number. If two regions have their top left cell in the same row, the region on the right will have the higher region number.) Digits along marked diagonals sum to the number indicated outside the grid.
The BBC radio programme Simon mentions in the introduction is called Just One Thing and the episode in question is available here:

Simon reads Kubla Khan by Samuel Taylor Coleridge at the end of tonight's video.

Thank you so much for the feature it was a really nice surprise to close the birthday of my daughter and I am really proud of this puzzle how it turned out just as exactly as I wanted. My daughter name is Luna by the way. And I also really enjoyed the video from start to finish and you hit all the logic I intended and I am really glad you enjoyed it the puzzle. I hope to see more in future and thank you for making my day better take care!

*Deconstruction* is always fascinating to me, and this *2x4* twist amplified my enjoyment to infinity. Of course, the elegant minimalism of the disambiguation gave me no opportunity whatsoever to attenuate my unconditioned awe for your genius. Seriously, this deserves to be included in volume 3 of CTC Greatest Hits. 👏👏👏👏👏👏👏

Happy birthday, Luna! Maybe this puzzle is a little hard for you right now, but, who knows, in a couple of years it could be just right. 😺

@bobblebardsley 16 дней назад

For several reasons, this felt like a good day for some *Rhyming Rules*... (this was not easy and I'm pretty confident I'll have made a mistake!) Within this special birthday grid eight 8-cell regions must be hid each two cells tall and four cells wide; can you determine where they hide? To fill the grid and celebrate, insert the digits 1 to 8 into each region, nice and neat (and in each region, no repeat). No region's neighbour overlaps (and digits don't go in the gaps). To keep the mood from turning solemn avoid repeats in row or column. A single loop now must be fit into the grid: it does not split and may not pass through 'empty' space outside the regions that you place. As through the grid, this closed loop snakes, its one-cell wide path never takes a route that meets itself too near (diagonally too, I fear). Along this loop, the digits fix, one 'medium' (from 3 to 6) the next 'extreme' (1, 2, 7, 8); so on, so forth, they alternate. In every region numbered 'N' the digit 'N' must therefore then be in a cell within the group which is located on the loop. (Region numbers are, by sight, assigned top-left to bottom-right; if still in doubt, just take a look which would come first if in a book.) And last, the little killer clues provide some totals you can use with knowledge mathematical to sum the marked diagonal. No matter how much time you take, reward yourself with chocolate cake for conquering the pinnacle of Dorlir's Little Miracle.

@TehFilmFanatic 16 дней назад

I have said before and I will say again: I encourage you to let go of your colouring sometimes! Once you had placed (almost) all of your blue cells on the loop, the blue/orange colouring is pretty much useless and can be removed. Then you don't need to juggle 3 overlapping colours and letters!

@57thorns 16 дней назад

Sometimes Simon rushes ahead and makes a beautiful deduction that is not needed. Sometimes he misse the easy path because he is blinded by the brilliance he sees. I can't blame him, I wish I could see all those brilliant paths instead of sloging on the easy ones. In this case it is to not finish what the 5 clue gives in the beginning.

@al129 16 дней назад

From before Simon starts with the letters, there is a 28 pair in Row 4 which would have resolved the route of the path through box 3 and identified where the 3 goes in box 3 and the 5 in box 5

@jetranger57b 15 дней назад

Was thinking the same thing - I think instead of the middle/high coloring he would have been better served by just using 1278 and 3456 pencil marks - then the colors for the disjoint sets would have been a bit more obvious..

@jonathanbarz9898 15 дней назад

love when you feature creative things like guitars/poems/etc! awesome puzzle too, i got the same regions but in a much less elegant way

@stevieinselby 16 дней назад

It baffles me how Simon can be so opposed to pencil marking, but it's more than happy to colour the grid into a kaleidoscope of incomprehensibility. I used three colours - not in a region, loop, not loop - I started to mark loop cells with the pen tool, X as extreme and circle as central, but fairly quickly switched to just using pencil marks, and it was really easy to keep track of what Simon had coloured pink, yellow and green just from the pencil marks. I did go a bit bifurcatey with the middly digits after hitting a brick wall for a while, but all in all a very fun puzzle. (Interesting approaches, at the start I went straight for the 5 diagonal and looking at how I could arrange the boxes to keep as many void cells as possible on the line, and quickly arrived at the basic pattern without doing any of the theory around the pigeonhole principle - and then using the loop rule to finish off placing the last couple of boxes like Simon did)

@nathanmays7926 16 дней назад

Assuming Dorlir loves his daughter as much as Simon loves Dorlir's puzzles, she's going to turn out just fine.

@Mennoo_ 16 дней назад

Fun fact: When I tested this puzzle for Dorlir, I thought it would rather be a 3-star puzzle (instead of him suggesting 4). To me there was online one step which was hinting towards 4-star, but turned out could be done much easier then I did in hindsight, proofing to me this would be a approachable 3star puzzle. But we got both very surprised that it turned out to be a 5-star puzzle on LMD. Where I benefitted from in my solve: Instead of having 2-sets of the digits 1-to-8 in yellow and green, i approached it the opposite way by rules of leftovers, obtaining that the yellow in c5 in green in c9 are the same 4 digits, and same for green in c5 and yellow in c1. Very much interconnected, but it makes the next step way quicker and more intuitive when you already got that in your head. Cause based on that I started to label my 3456s with letters very early. And only at the very last moment i replaced those for the actual digits Funny how difficulty sometimes can be so subjective. Nevertheless, it's an amazing puzzle by Dorlir once again and really deserves the feature on this specific day. And I agree with Simon. How on earth does one set this (or maybe in this case, discover this?)

@MattYDdraig 15 дней назад

34:48 This was a rollicking rollercoaster of a puzzle, graphing confusion, excitement, wonder, and curse words. The first glance looks ridiculously impossible then suddenly regions come into focus and it seems like it won't be all that tough and then it fights back again and again. So many beautiful deductions needed (I particularly liked - swore at - the disambiguation on r8c5) before finally we could loosen our seatbelts and run to the back of the queue for another ride. Incredible work, dorlir, and I hope Luna had a very happy birthday 🎈🎂

@toms7114 13 дней назад

Thank you Simon for all you've taught me about solving sudokus, because I spotted a swordfish on 8s in columns 2, 3, & 4 placing an 8 in r6c1 as soon as you pencil marked the 8s in boxes 1 and 3 at 1:01:00 into the solve. The first swordfish I've spotted without pencil marking every digit possible in the entire grid.

@titusadduxas 14 дней назад

1:25:54 - That was gorgeous. Getting the boxes and the loop started was pretty straightforward but lovely logic throughout.

@laurv8370 15 дней назад

It took me exactly 10 seconds after reading the rules, to find out how the boxes are arranged - from the 5 diagonal clue, the diagonal can not visit more than 1 cell in each box, otherwise the sum would be at least 6, which immediately gives out the position of 1, 2, 4, 5, 7, 8 boxes. Then there is only one way to place 3 and 6 without breaking the grid in two separate parts (which would forbid the loop). And I was so proud of myself... Then I got stuck and watched the video ☺️. Kudos to Simon for solving this, and especially to the composer of this beauty.

Your subconscious regarding the central cell was quite simple! As soon as you realised that the black cells in R3C6 and R6C3 would push the regions up or down, then your previous idea about an orange 1 in the centre as part of a region extending northwest or southeast is invalid!

@TheBestThatICouldDo 14 дней назад

Dorlir is not a setter one tends to fear because he doesn’t mind making a puzzle that is extraordinarily easy if the ideas are interesting. But, by the same token, there doesn’t seem to be a limit on how deep and complex he is capable of going to explore some really beautiful logic.

@andremouss2536 15 дней назад

29:50 An obvious point now : the loop cannot pass from region 6 to region 5 as it wouldn't be able to get to region 4 then. So the loop goes from 6 to 4, then 3, then 5, then 3 again and it unveils a lot of things about its path (for example, it must then go to region 1 first and end in region 2)

@gi0nbecell 16 дней назад

As for the commentary on reading poetry out loud: For me personally, poetry doesn‘t work too well. I do enjoy it, at times - but I prefer (for lack of a better word) humoristic poetry. When I’m in the mood, I mainly read that. If it is able to make you think about it, even better. And thankfully, my good old Germany is rich with such poetry, from Christian Morgenstern (who once concluded in a poem that the accidental death of his main character was just a dream because the cause of the accident was unlawful - and it is clear that things that aren‘t allowed to be, can‘t be [Die Unmögliche Tatsache/The Impossible Fact, if one wants to look it up - don‘t know if there is a translation into English]), to more philosophic humour like Joachim Ringelnatz, and of course the group around Robert Gernhardt, Ror Wolf, Thomas Gsella and Steffen Jacobs. Still, this is highly situational for me. However, I also use a form of art to relax. For me, playing the piano replaces reading poetry out loud. After a stressful day in the office, or even after a particularly nasty work appointment or phone conference when I‘m working from home (I just walk into the next room and take those few minutes to cool off - that allows me to resume my work with new optimism and energy), after a fight with friends or relatives or when I‘m just a bit down, it helps me tremendously to just sit down at the piano and play some easy pieces I learned years and years ago - five minutes, nothing special, nothing new I would have to practice, just some nice melodies close to my heart have a tremendous impact on my mind. Having such a remedy for stress, and even making a habit out of it to just do it daily (not withstanding actually learning new pieces that could eventually join the portfolio of favorite melodies) has had an enormous impact on my mental wellbeing. Buying my current (electronic) piano after years without an instrument in my life was one of the best decisions and purchases I have ever made. Besides that, I also use cooking, and here particularly preparation (peeling, cleaning green beans, cutting vegetables - all that) can have almost meditative character. That‘s not just five minutes, though, and not an easy, accessible outlet…

@JimmyLundberg 16 дней назад

Lovely puzzle; I rarely get involved, but I just had to solve this one. The broken up rows and columns complete each other, respectively. In the video, rows 3 and 7 found each other on the pink road, but columns 1 and 9 never managed to fully cross the golden-green bridge on c5. I found the logic beautiful, so I thought I'd point it out. Roads and bridges are optional; the keen-eyed among you may find more direct connections. 🔎

LOL, my solve time says it was 200 minutes, but it didn't pause and it was more like 75 minutes. I got MOST of the way there in like 40 minutes. Just didn't see how to proceed, ended up bifurcating, and then noticed that r8c5 saw both r2c5 and c8c9, meaning it had to be the same as r5c9 (due to region logic I used to show that the eight cells in boxes 2, 4, 6, 8 and columns 5 and 9 had to be a set of the digits 1-8). I placed the cages thanks to the 5 clue in about 3 minutes.

At 49:25 Simon claims that if he has a 1 in box 6 on the line, then he has that 1 in box 5 also on the line, but isn't it not obvious why that's true? The issue to me seems to be that you could try and put it on the bottom left square on box 5 too, but then it breaks the 16 diagonal.

@RichSmith77 16 дней назад

He already knows the 12 pencilmarks in boxes 4 and 5 are a true 12 pair, i.e. are different. (One's in purple, the other isn't, so they cannot be the same). That's why he says if that particular cell on the line in box 6 is a 1, then since that's not in purple, it has to go in the non-purple cell of the 12 pair in the 5 sum too, hence on the line in box 5.

Okay, so you absolutely should not feel bad about not spotting the trick with the 6s in R8C5 and R5C9 sooner (1:14:40). That was objectively hard and quite beautiful.

By convention "touching diagonally" doesn't include that, only the instances where it comes back around from another direction. You're not the first person to find that wording confusing.

@@Anne_Mahoney Thanks ☺️ I was being slightly facetious about it but it is a difficult rule to right clearly and succinctly.

I think you massively overthought how to find the "centers" of the boxes that must be filled in any arrangement. I would've just shoved all the regions in the upper right, then shoved all the regions in the lower left, and the overlap trivially gives you the arrangement of 3 cell starting regions

Five stars was what Simon had spoken. Why surely the man must be jokin'. So I say hardy hars! It deserves seven stars! For that's how many times it got broken! True story. I broke the durn puzzle seven fluffin' times!

one thing about parity loops or lines that Simon has missed in multiple videos so far is that every single cell has an odd or even number of moves toget to. nomatter the detour, a cell that takes a even number of moves to get to in one way will ALWAYS have an even number of moves to get to (as long as the line consists of orthoganally conmected cells). that gives the two possible cells that 3 can be in within the third bix right away. the reason for this is that any detour is essentially a move in one cardinal direction that then has to lead to a second move going in the opposite direction. each detour is therefor adding an even number of cells. and if you add an even number to either an even or an odd one, the parity never changes. I have commented this on at least one video in the past where he figured it out in a way more complicated way. this is a basuc rule that always applies with such loops or lines with parities edit: of course it's extemes and middle numbers here but the logic still applies.

@RichSmith77 16 дней назад

I don't think it's accurate to say Simon is unaware of this. He just expresses it in terms of the chess analogy of "bishop's colours". His "middley" digits (orange) are always on one bishop's colour/diagonal and extreme digits (blue) are on the other bishop's colour/diagonal. He uses this analogy in puzzles frequently, for an orthogonally moving path that alternates a property along its length.

@RichSmith77 16 дней назад

@@jurgnobs1308 I don't know when you think he was struggling to come to terms with this, but as I see it, he only starts thinking about the digits alternating between middly and extreme along the loop when he removes the orange colour from all his 2x4's at around the 30 minute mark. Within twenty seconds he's referring to bishop's colours applying throughout the grid. This is something Simon is extremely familiar with.

@RichSmith77 15 дней назад

@@jurgnobs1308 He uses his "bishop's colours" when fixing the position of 1 in box 1 though. (34:45) There may be opportunities to do more pencil-marking, such as the three (not two!) possible locations for 3 in box 3, but he must simply decide it's not worth it, at this stage. He then spends some time looking at SET/geometry of the grid and making some useful conclusions in that area. Just because he may not see, or take, an opportunity to apply his bishop colour's logic at certain points isn't a reason to accuse him of not understanding it, though. If that were the case, you may as well accuse him of not understanding the standard rules of sudoku every time he overlooks the possibility of doing some basic sudoku. 🙂

290 minutes, and my final solve came down to "Ok, if X is in this spot, how does it break? It does this, and this, and this....and that's a solve. Huh..." But this is probably the hardest puzzle I've solved without needing a hint from Simon, so I'm calling it a win.
