Sigma Pi - A Sudoku Masterpiece

[@rhysm2526]

A capital sigma is notation for a summation and a capital pi is notation for a product.

[@rhysm2526]

So in some sense the rules of the sudoku are encoded into the grid itself

[@Akatsuki69387]

A delicious product

​@@kamalidimock8726yes! I would love to talk to him at a party as long as I knew to ask about puzzles and classic rock

[@mathijs58]

Simon claims he is not much fun at a party, but he is surely a master at parity! Spotting that trick in the top right corner was beautiful!

[@bobblebardsley]

*I call this one 'Spoilers'...* A brace of lines spell sigma pi, their tips the factors of their sum. Now what can those rules signify? What depths of logic must we plumb? Our arithmetic acrobatics must avoid the numbers prime; whose factor-phobic mathematics would, in this grid, be a crime. Now bend ye, clues, to our persuasions, cracking cunning as a fox, with simultaneous equations held within a single box. Alas, alack, there's ambiguity; Goodliffe candidates, and then? We cue anew our ingenuity, seeking sums that add to ten. No nearer to a solved solution, still we're probing, ever hoping. Suddenly, a revolution: in the central stack, there's roping. Eliminate the awkward parity, make the line's remainder fine and here at last, a singularity: a digit found, we've gained a 9. Colour, fill, yet still conflicted; briefly felt like we're away. Neighbour lines still not restricted, now we ask: "What can we say?" And here's another indication from deductions quite propitious: the only working combination makes the corner cell auspicious. There's 3 in its corner spotlight; there's 3 losing its religion! Clear the purple where it's not right, from the conflicting position. Now we look for further progress; how next will this quiz be solved? A little line adds extra duress: two more factors are resolved. Filling now with newfound power, pencil marking with a flurry; the timer ticks beyond the hour. Bobbins, bobbins, time to hurry! O parity, our faithful friend, bestow on us a logic ripple; regardless how the line may end, we know it leaves us with a triple. With this pivotal deduction, now we near our destination as some logical reduction leads our last elimination. Tidy up, complete the test, another solve with wits astute: we gave our all, we gave our best, we give our thanks to IcyFruit.

[@strangest_cacti]

Utterly brilliant puzzle! I actually feel like IcyFruit's logic is quite distinct from Phistomefel's. If anything the intricate clue geometry giving rise to mathematical tricks is very Zetamath-esque.

It's Pinky from Thailand. Thank you CTC for the birthday wish. As always amazing solving by Simon. I have watched for a year or two now and I should give Sudoku a go. I used to do normal sudoku when I was young, now I'm going for it again.

[@MarushiaDark316]

I would love to talk to Simon at parties.

[@TehFilmFanatic]

Ahhh, this was lovely! I solved this the other day when it came out, but got very stuck in the top right corner. I got it through an exhaustive search, but the parity trick makes that much smoother!

[@emilywilliams3237]

This was interesting, and definitely a constraint/line type worth watching for other examples of. I enjoyed your solve, Simon, particularly the work using parity in box 3 and environs. I will never try this puzzle - too far above my ability - but certainly would watch another video featuring this idea. Thanks!

[@Koppen8]

I actually started watching this channel because it got me sleepy, but now I've realized that these puzzles keeps me up at night unfortunately hahah. Love the content!

[@HunterJE]

Weird deduction I'm noticing at the start (so no clue if Simon uses this :EDIT: yep he did, if not so explicitly algebraically) on the three cell lines with Xs - if you define the ends on the X as "A" and the other end as "B" you'll find that 10+B=AB, which rearranges to A=(10+B)/B. If you start plugging in possible valid sudoku digit values for B and see which give valid values for A you'll quickly find that you are VERY limited, and indeed can only put in 2 and 5 (12/2=6, 15/5=3), hence you can pencil mark the X ends as 36 and the non-X ends as 25 (and for that matter the middles as 47).

[@WhoStoleMyAlias]

Yes, those were pretty much giveaways as they only work with [37] and [46] pairs. Like Simon I didn't appreciate them enough though and initially focussed on the boxes that seemed crowded. Only after that did not get me anywhere I thought about verifying whether those two lines could contain the same digits. It's really not that hard a puzzle from that point on.

[@timvermeulen4024]

Even better than plugging in all possible digits: 10+B=AB can be rewritten as B(A-1)=10, and 10 can only be factored as 2*5, so it immediately follows that B is either 2 or 5.

[@jdcheetham]

if this audience didn't find this interesting, they wouldn't be here.

[@noahvale2627]

Simon would find me boring at parties.

[@ethanchoo]

I love how sigma and pi means summation and product, but the symbol for sigma and pi are also forming the lines in box 1 and 9. Beautiful!

"What am I supposed to do now?" asks Simon. Answer: Sudoku, Simon. Sudoku! You never saw the X-wing on 7's in rows 1 and 3 resolving the 7 in row 2 on the end of a brown line. You solved it anyway, so fair play. Thanks for the video, and thanks for the puzzle. Extremely entertaining, as always.

[@AngelWedge]

14:56 … I thought that the two sums have to add up to 45, so one of them must be odd. Can't have both numbers being multiples of 5, and 1 can't go on the end of a line, so the lines in box 7 can only be 21+24 or 27+18… and one of those is immediately ruled out because there are too many 3s in their combined prime factors.

[@Rubrickety]

This is a beautiful puzzle firmly in the "Glad I gave up on that one!" category for me.

[@anaayoung9142]

Very fun solve Simon. I didn't dare to try it, so I only watch your solve 🤗 One thing that bothers me is about you trying to hold your sneeze. You should not do that! Altought is rare, is could damage blood vessels in your eyes, nose or eardrums due to the increased pressure. If you want to sneeze do in your arm it is ok to do that 🤧 I am always worried everytime you say "don't sneeze" 😖

[@Kheldar633]

One suggestion you might consider for future videos is including the Secrets of certain common variants (Yin-Yang, German Whispers, Renban Lines, Killer Cages, etc.) directly at the end of the rules so that those familiar with them can skip from that point in the rules to the start of the solve. That way, newcomers still get the Secrets, but fans can jump past them. Maybe it would be a special section titled Secrets. Just a thought.

[@RichSmith77]

I did something very stupid during my solve. Like Simon, I'd worked out the three cell lines with Xs were 246 or 357. Like Simon, I discovered they couldn't be the same, as they'd break the line in column 5. Like Simon, I worked out column 5 was (18)9...4. Like Simon, I realised this made the three cell line in box 8 a 375 line. Unlike Simon, and any sane person, I promptly entered it as 573! But 5+7 ≠ 10!!! It took me a further hour before that error finally broke the puzzle for me, and came to light. Arghhh!!! Once I was back on track, that parity trick in box 3 was beyond me. I had to resort to lots of case testing for the various options. The parity trick was genius.

[@benjaminvazquez1243]

A cry for help to the CtC community. I had put together a list of about fifty puzzles from this channel which I was going to send to my mother over Christmas. Selected to be beginner friendly without being trivial and building upon each other so that each puzzle in the list pulled something from the one before it. And yesterday I lost everything to a computer glitch. I'm going to work back through the channel's back-catalogue over the coming two weeks, but does anyone have any puzzles they can recommend? Puzzles with logic enough to be worth sinking your teeth into, but not so complicated that they're likely to turn a beginner away. Videos from CtC that are a step above the GAS puzzles?

[@LiquorStoreJon]

[@gredangeo]

I don't know when the last time Simon has shown a pure basic sudoku puzzle. No other rules. Just a few numbers in the grid. Whole thing labeled Expert, (or even Pro, perhaps). I'm curious to know how long it would take to solve that benchmark for a puzzle. Sometimes, it's difficult to grasp, just how difficult these puzzles are, based on how good Simon is at these. I often wouldn't know where to begin with them. Especially for those were you have to draw out connected shaded regions. But as Simon shows the steps, it all makes logical sense. Solving many of these in about 60-90 minutes is impressive.

[@chocolateboy300]

I finished in 188 minutes. This was a really fun and unique ruleset. I really enjoyed the break-in using roping. I got stuck in the middlegame before seeing that I had already proved the value of a line but didn't follow through with the other digits on the line. I was wondering why it got so hard and it was just me missing the obvious. Great Puzzle!

[@henk-ottolimburg7947]

Math for the line of three: Search for 3 numbers, a b and c a*c = a+b+c, where a+b = 10 A*c = 10+c A = 10/c + 1, and it should be an integer. c = 2 or 5 a = 6 or 3 resp. 6-4-2 or 3-7-5.

[@Yttria]

Clever but brutal puzzle. Only part of the logic I missed (and needed Simon's help with) was the roping constraint of boxes 2, 5, and 8. That said it was still a brutal solve and required looking at all the combinations of numbers for the rest of the lines to solve. After watching, it's clear I missed many of the logical shortcuts while brute forcing through.

[@theanalogkidmodular]

For future puzzles the list of all valid solutions for a 7-cell brown line contained in a 3x3 is fairly limited by the secret - only 12. Moreover, all but one have either a 4 or a 5 at one end (e.g., 4/7 ends + 8/9 in the remaining cells, 4/8 ends + 7/6 cells, 4/9 ends + cells adding to 9 without 5/4, etc.), the only remaining solution is 6/7 with 1/2 in the empty cells, which is the one you correctly got around 40:00.

[@theanalogkidmodular]

So for example at 51:40, using the list of possible solutions the only ones with a 2 in the empty cells that remain after ruling out 5/8 and 6/7 at the ends are 5/7 ends with 8/2 cells and 4/9 ends with 7/2 cells but the latter can't be for sudoku since there is a 7 in the first column already. That leaves with the 5/7 ends with 8 in the remaining empty cell, as you correctly find later.

[@prettykittycat9281]

"No Jokes" Like Simon was reading my mind!

[@indraneelperuri2320]

at 40:06 , he looks like sheldon from TBBT

[@Raven-Creations]

This was fascinating. I started with the 3-cell x lines, did a bit of maths. If the cells are ABC where A+B=10 and AC = A+B+C=10+C, we get (A-1)C=10 and discovered there were just two solutions using sudoku digits. If both lines are the same, we end up with either 246 or 537 in box 2 C5. No arrangement of these lets the line in C5 work, so one x line is 246 and the other is 537, and we have roping. The unused digits, which appear in C5 in box 2 are 189, and these can only work if the 18 are off the line, with 9 on the top of the line, and 4 on the bottom. The 4 disambiguates the x lines. The starting handle has 89 on the right end, and 23 on the left. I then moved onto box 7, where I reached the same conclusion as you - "that's annoying". The digits I'd already placed did reduce some of the options though. After that, it required a bit of a slog, but each time, this was cut short by realising that there was enough information to place some completely unrelated digit. Much like when you got the 2 in C3, where you did just enough to realise that 2 couldn't go anywhere but in R2C3, which removed the options for the line in box 1, and this then forced the resolution of the original problem. There was a similar process with box 3. @ 41:18 - "Does this not get resolved any further than this?" - Yes, use sudoku. 2s are aligning in boxes 7 and 9, resolving the 26 pair, which in turn resolves the 46 pair @ 1:06:14 - debating what goes on the last x. If you'd done sudoku, you'd have realised that both 3 and 7 have to be in C8 in box 6, so the x is 46. Similarly, the 7s align in boxes 1 and 3, so R2C6=7. The long line cannot be 4 times 7, 24 + 11 is already more than 28, therefore it has to be 6 x 7 = 42 on the line 42 - 24 - 13 = 5, so R3C6=5. @ 1:08:59 - "Aargh, the 4 and the 8 don't get resolved" - what about the 4 in R4C7? This wasn't easy, but it was a fun solve, and very rewarding. Many of the discoveries were quite surprising, given how the thought process usually revealed some weird side-effect that was unrelated to the immediate problem, but moved the solve along significantly, all before the original deliberations were complete. I'm not sure Mark would have fared well with this one, because when faced with a challenge, he seems to get tunnel vision, focussing on the specific problem to the exclusion of everything else, and because the effect of deliberations was often unrelated to the problem being considered, he may well have missed the side-effects. This reminded me of a Rocky Roer puzzle, with the maths and the elegance. I hope IcyFruit isn't going to start a one-upmanship battle, because this was mentally challenging enough for me. It's not that I'm incapable of doing harder maths, it's that it starts to feel more like work than pleasure. Although your sudoku let you down a bit, it was still a decent solve by you today.

[@JorgePacker]

Amazing solve as usual! My solve was a messy path, you just go in a straight line! Impressive! 👏

[@johnh2052]

At 1:01:18, there is an elegant way to deduce the X in box 6. Simon noticed the 3s aligning in columns 7 and 9, which forces a 3 into column 8 of box 6. However, the 7s also aligned in those columns, which also forces a 7 into column 8 of box 6. This means the X can only be a 46-pair. And only the 6 works on the length-7 line. Note that I didn't see this in my own solve, which involved some brute force at this point, but I did see it when watching Simon's.

[@johnh2052]

At 35:30, box 9 can be largely figured out. The endpoints of the length-7 line are 4 or bigger. And with 4 and 5 no longer available, the only workable option is the next two smallest digits: 6x7=42. And that differentiates the two lines in box 7. Edit: Never mind. He sees all this just 5 minutes later. :)

[@Chriib]

A straight mathematical approach from the beginning helps a lot. If we consider the line in box 5 and label the positions, from bottom to top as a, b and c we can set the equations a+b+c=ac and a+b=10. From here we can conclude that c=10/(a-1) and b=10-a. Considering that a, b and c have to have different integer values from 1-9 the line can only be, from bottom top 3 7 5 or 6 4 2. The same idea works for the line in box 8.

[@bruceh8043]

[@frankjiang1857]

Finished in 47:15. I first tried to calculate all the different variants of the lines while not on the clock, but I messed up in one of my calculations which led to a wrong conclusion, so then I recalculated everything. But then I found out that I couldn't find an appropriate set for box 3 which lead to some recalculations and realizing that I left out the 37 variants for the 5 cell lines randomly. I guess my advice would be make sure you have all the variants correct before working on the puzzle as it's pretty straightforward if you have all the variants correctly figured out....

[@robertcousins2274]

31:45 for me

[@jeper3460]

I was wondering how you ruled out 7 from R4C8 at 1:06:13. I did my own deduction using the brown line. If R4C8 is a 7, there are two possibilities for the sum of the brown line: 35 and 49, because R2C6 is either 5 or 7. If R2C6 is a 5, that means the brown line adds to 35. The square formed by R2C7 and R3C8 already adds to 24, and the ends add up to 12. 12 + 24 = 36 > 35, and there is still one more digit. If R2C6 instead is a 7, that means the line adds to 49. Again, the square adds to 24, and the ends add to 14. 24 + 14 = 38. That would mean the last square of the line would have to be 11, which is nonsense. Both possible line sums with a 7 in R3C8 have been eliminated. Therefore R3C8 is not a 7. Q.E.D. (Simon probably solved this in a much easier way that I just couldn’t see)

[@Trottah]

Simon found an X-wing of 3’s in boxes 3 and 9, so had pencil marked 3 in to box 6, column 8. If r4c8 were a 7, the X would have put a 3 in r4c7 and there would have been no 3 in c8.

[@gilbertschwarz2829]

Phantastic puzzle, phantastic solve with some really clever ideas. Kudos again! Minor little miss towards the end, shortly after the phenomenal par(i)ty trick: 5 had to be in row 2 in box 3 by box logic, which disambiguates a lot in box 2. I'd wager that was the intended path.

48 minutes, but I really needed that piece of paper to keep notes at the side... beautiful puzzle

63:20 for me. Beautiful puzzle!

[@philwheatley5057]

Well aren't I the clever clogs. I have astonished myself this morning by finishing that one in 27 minutes! Just churning combo options as fast as I can. Not as elegant as Simon but pretty effective

[@jacob9692]

[@TriforceOfCourage97]

[@TPH250290]

cheers.

Simon's joke about being boring at parties has definitely passed its use by date. You need some new material Simon, you're getting VERY repetitive

[@stephenbeck7222]

Simon never claimed other people would find him interesting nor funny. Yet here we are commenting on what he says.

[@traviswilliams3034]

You mean to tell me you've heard all his jokes before, but he keeps telling them at the party? How droll

[@Antiknight]

00:27:36 for me! Just fiddled around with numbers until I got the right combination but interesting rule to say the least.

[@davidrattner9]

Is that your new way of solving now...just fiddling away? 😉

[@Antiknight]

@@davidrattner9 haha maybe for new constraints :P
