Why does being one of Simons favourite people feel so big of a confidence boost...

[@justatest90]

Between Simon and Ann Reardon watching out for me, I'm gonna be OK.

[@KevFrost]

Ah, the answer to that is a secret that he only tells other genius sudoku solvers

[@margaretsinclair6697]

Simon is one of my favourite people. Unfortunately, that probably doesn’t give him as much of a confidence boost as being one of Simon’s favourite people does for me.

[@zadrik1337]

Are we sure Deep Thought got it right? Maybe the answer is really 45.

I can't believe that I managed to solve this one. Sorry for showing off, but it's the first Cracking The Cryptic variant Sudoku puzzle that I've managed to solve. I'm quite chuffed.

[@ailurophile47]

Congrats!

[@OrphicMonkey]

The feeling your first CtC solve gives you is certainly a rare one.

[@Char42]

Funnily enough I imagine this puzzle would have been harder WITH the given diagonal sums.

[@57thorns]

Not really given the break-in would end up being the same.

[@whatsleep17]

Totally agree!

[@michielgerretzen9777]

Surely it does, as it would not gear you automatically into the right direction most likely :-)

[@nonyobisniss7928]

I had a go at the puzzle with the totals in place, to see if it could be easily solved without summing all the little killers as had to be done with the ? version Simon solved. As far as I can tell it's totally impenetrable!

[@nonyobisniss7928]

@@mikhailtatmyshevskiy2666 Yes, and I could narrow down some of the arrows a bit but not enough to get any digts besides the 7 and the 3 from the one cell arrows. I think this given framing of the puzzle is most fun for the solver, but I also think it would have been fun to give Simon the puzzle with the arrow totals and see how long it took him to think of summing them all. Most likely he never would have, and would have just given up and never release the video, but it would have been an amazing moment if he did come up with it unprompted.

[@David_K_Booth]

A very witty puzzle - despite provoking an initial response of "What on Earth am I looking at?", it flows along quite easily after the break-in. Nice work, Gliperal.

[@SirJefferE]

"Witty" is probably the best word for it. The puzzle is set up almost like a joke, with the solution to the break-in as the punchline. I opened the puzzle and thought "This is completely impossible, and I'm never going to solve it unless the triangle number in each box for every cell on a diagonal, assuming repeated digits are the lowest values possible, adds up to 178." So I add them all up, and the sum is exactly what I hoped, and suddenly all the tension of "What if this doesn't work" is relieved. What else can I do but laugh?

[@thomasknapp6434]

@@SirJefferE Yeah, that was exactly it for me. I was like, "God, I hope all this adds up to something really close to 178." When it all added up to exactly 178, it was a immense sigh of relief. I doubt I have that sort of permutation math in me if it hadn't.

[@yerel_nimni_avni]

Simon, couple of years ago: WHAT THE H, puzzle with only 2 digits and a lot of constraints, that's must be a practical joke that Mark pulls on me. Simon, today: AMAZING, FANTASTIC, AWESOME, a puzzle without any seemingly clues in. Keep that phase up, we love it.

[@Valnoyez]

I find it incredible that after regularly watching this channel for a few months, I am now able to solve sudokus like these (22:45). The way Simon and Mark are always explaining their thought process is a very effective way of teaching the logic that goes into solving all these different variants. This really is a peculiar but very nice little corner of the internet :-)

[@felis_timon]

This puzzle took me around 8 minutes. I think I won.

[@claudioestevez1028]

If my grandfather gave a speech about his grandsons it would have a similar composition of words as this video.

[@Gliperal]

Aha Simon, you fell for my trap! You see, this puzzle is actually (pause for effect) computer generated--your very own mortal enemy! All jokes aside, this is one of those types of sudoku where the difference between a computer generated puzzle and a handcrafted one is hard to tell. When I started on this endeavor, I just wanted to find a grid with a low number of solutions, and hopefully add an extra rule to disambiguate fully (something like "none of the diagonals sum to 13"). Imagine my surprise when I found an arrangement of little killers with only two solutions, a deadly pattern on 8s and 9s. Well now that put me in an awkward spot. I could have released that puzzle, but it's a bit of a shame having to add an extra clue just to disambiguate a single deadly pattern. And since it only took me two days to find one with 2 solutions, I was reasonably convinced that a single solution pattern existed. Ultimately I decided to write a program to brute force it, because that was not too far off from what I was doing anyway. I would throw some long diagonals into the grid until it got reasonably restricted, and then start randomly fiddling with the short diagonals, guided by the solution count button. Rangsk's solver (which you can find on the discord) was a huge help, dare I say made it possible in the first place. You realize quite soon that it's hard to have 1 solution because you need almost every box to disambiguate a pair of digits (you need a box with 8 cells covered to disambiguate 89; you need a box 4 cells covered to disambiguate 45; etc.). But it's slow for a human to change a diagonal and then re-pencil-mark every box that's affected and run the solver again. So I wrote a piece of code to do basically the same thing: randomly place diagonals, avoid 0 solution grids, until it hit a minimum. By the time I stopped it, the computer had found 14 arrangements of little killers with exactly 1 solution. 7 of these were simply not logically solvable. 3 of them were downright trivial, with one surprise disgusting step near the end. 1 of them I rather enjoyed, but it did require a lot of advanced techniques to solve, so miss one of them and you were probably gonna have a bad day. And the last 3 were relatively easy. I put one of them up for testing that had a lovely little coloring step near the end on 67 pairs, but even that was missable. Ultimately I settled on this one. Visually nice, with the diagonal triplets on both sides (fun fact, you can remove the top right one-cell diagonal and still get a unique solve); a relatively low total for the maths required; and the best feedback from testers. TL;DR Computer generated, but heavily curated, and using the computer to do basically what I was doing already.

[@jurjenvanderhoek316]

Brilliant! Very interesting stuff. But what is a "single deadly pattern"?

[@Gliperal]

@@jurjenvanderhoek316 After filling in all of the 1s, 2s, ... 7s, every single cell remaining could be either an 8 or a 9. Getting a single one would collapse to a solution, but no diagonal passed through any of them, so there was no way of knowing.

[@davidrattner9]

Absolutely brilliant from you and thank you so much for the little trivia information about how you came up with it!!

[@chrishydahl4580]

@@jurjenvanderhoek316 If you have filled in every digit except from only two identical pairs, let's say an 89 in two boxes. They could be solved: 8 | 9 or 9 | 8 9 | 8 8 | 9 And both could be right, meaning there are two solutions to the puzzle, which is not good.

[@iceberg54321]

Yah, I could tell a computer helped set this one.

[@earthimmigrant]

Before I discovered this channel a little less than a year ago, I had no idea sudoku was anything fancier than the standard classic puzzles. Never heard of variants, X-wings or even pairs, barely had any strategies or techniques other than excessive pencil marking and bifurcation. Today I started this video, got to the reading of the rules, immediately thought “well that’s easy, they must be minimized or that would never work, I gotta try this one before watching it,” and solved it smoothly in about 30 minutes. I’ve learned so much watching CTC videos, and I look forward to learning more every day.

[@Mikeyjoehalo]

Just in case anyone else who missed Simon's logic at the beginning sees my random comment here, thinking about it helped me learn something about puzzles. Because he's way better at puzzles than me, he quickly said "Let's try minimizing or maximizing cells." I thought he was fortunate it worked out, but then I went back and thought about it and it made perfect sense. Because my first thought was that trying to figure out which random selection of N values sums to X was impossible. But that's actually correct - it IS impossible. Which means that the selection of N values ISN'T random, it's specific. So if we can't know quantitatively what the values are, but terms like "the minimum possible" and "the maximum possible" are specific, even if we don't know what they are yet. Really really smart and helped teach me something about puzzles.

[@Halfbeasty]

14:12 for me, very fun puzzle to solve. This was definitely one puzzle that made me go "I'm so glad this exists"

[@JannaWillard]

I literally just found this channel yesterday and this was the third puzzle I tried along with you. It was SO FUN!

[@KyleBaran90]

Because it was only 25 minutes long, I knew it would be an easy break-in, so I gave it a quick shot. Looks like the trick was to find the overlap on positive and negative diagonals, and minimize everything, giving a total of 162; the overlaps account for the difference of 16 and require the smallest digits in their box. Very cool

[@GioPanStudios]

Amazing. I don't think I've ever seen a puzzle that's so approachable for how daunting it seems at first glance.

[@Chocy-Star]

Can we just take a moment and appreciate the hard work done by both Simon and his Laptop while he's on a holiday

[@davidson2004fatboy]

CALLED, HAVING NO LIFE ! IF that's WHAT U APPRECIATE ? I'M VERY HAPPY 4 U

I don't usually watch these short videos, as I rather use my limited time to watch the awesome 1-2h solves, but I'm *super* happy to have opened this one for some reason. After Simon filled in the purples I realized what the trick was and had to solve it myself too just because it was *so* neat one. Congrats to the setter!

[@onijester56]

The 1-to-2-hour solves are for after work when I'm having my glass of wine/whiskey/vodka/all-the-above to fall asleep. These short solves are for when it's a night I have off (since I work night-shift) and want to chill with some mozz sticks.

[@apiyo_puzzles]

Gliperal is really one of my favourite setters. Never fails to come up with something completely original, and often something that most of us would never think was even worth investigating as an idea. Bravo!

[@RoselynTate]

I will never fail to be amused when Simon uses much more complicated logic to explain why he can't put a number in a cell when the simple explanation is that it's already placed in the row column or box. Especially when he's literally just referenced that exact digit for another deduction. (In this video, that would be in particular the 4 in R3C6, and the 6 in R4C2) Please never change, Simon. 🥰

[@lorenzadenarus]

After seeing the length of the video I expected an easy break-in and was not disappointed. Really good contrast to the Phistomefel puzzle from yesterday! Thank you for finding those great puzzles.

[@ItsMeBenson]

The joy I felt when Simon discovered the minimised purple cells sum to 178 ☺️😂

[@craftypam9992]

My first thought is "why did he use purple on all the diagonals, then try to spot the duplicates?" If the positive diagonals are one colour and the negatives a different colour, the duplicates are obvious!

[@ChrisVenus]

Yeah, that's exactly how I did it and made it nice and easy. I often wonder why simon refuses to have sets made up of two colours like this - it would often make the set stuff he does look a bit more obvious (IMO) if he used one colour for columns and one for rows or something like that. Scrabble bags can have tiles of more than one colour in the same bag! :)

[@lomax343]

I wish I'd realised that before wasting time looking for one degree of freedom, because I'd missed one duplicate...

[@lauracortes7720]

very good point haha

[@HunterJE]

16:47 Fun observation here, even though the white cells in the box can be as low as 5, r2c6 must be 7 or higher because of the column - none of the boxes in the central columns can have a 789 in their purple, and as such the 789 in column 6 must fill the three white cells in that column.

[@HunterJE]

Also great puzzle, wouldn't at all be surprised if this goes around the way Miracle did and gets y'all up over 500k.

[@jamaicanbutter]

I was astonished that this worked itself out so smoothly. This actually reminds me of one my favorite cracking the cryptic solves which was "The Miracle by Mitchell Lee". This Puzzle was equally impressive. Great video!

[@85TITZ]

"I only tell my favorite people.." oh. "Luckily everyone that is watching this video are my favorite people" IMMEDIATELY STARTED CRYING

[@timcotton1782]

I used the pencil tool to mark the diagonals, green to mark the double-counted cells, and medium gray to mark the cells not counted by the diagonals. After summing the boxes (happy to see that Simon chose to do the same) minimums to 178, the puzzle became a fairly straight-up medium classic sudoku. Around 13 mins to make certain of the 178 setup, finished in 21:58. An amazing build, with no givens, one fact leading to one possible idea, and one possible path to the solve. Ingenious is an understatement.

[@clockworkkirlia7475]

I'm very new to fancy Sudoku so I immediately wrote this one off as a "Let's watch Simon" sort of video. Then, of course, as soon as I saw the 178 trick with the overlaps, I had to give it a go! Still took me eighty minutes after I filled the screen with pencil marks, which shows how new I am, but this channel is really giving me the Sudoku bug.

[@Lurvification]

That was really satisfying and an amazing solve! Especially when the purples did add up to 178.

[@riley3913]

Best puzzle I’ve seen on the channel so far, thank you for sharing!

[@emilywilliams3237]

Another very fun "holiday edition" from you, Simon. A fun puzzle, which I am pretty sure I can solve myself if I sit down to do it (and I am looking forward to finding time to do just that). The result, that you had a great time, was evident - and that is one of the pleasures of this channel for me, to watch you (and Mark) enjoy yourselves with puzzles that are good, robust enough to be a bit of a challenge, and yet not terribly difficult. Thanks for emerging from your holiday again to post a video for the channel. I can say for myself that I very, very much appreciate it.

[@FrancisPollen]

Yesss, just solved this one the other day. Excited to see Simon's solve. It's a fun break in.

[@misterroboto9999]

Hell of a convoluted break-in, yet left me grinning ear-to-ear the whole way.

[@philipstaite4775]

Ah, I started down the wrong path. I colored the marked diagonals, but then focused on the remaining white cells and 405 - 178... Hit the obvious roadblock there and then watched Simon get to the minima. Once you recognize the minima constraint everything else falls out as good old Sudoku. Very clever puzzle!

[@wanderlustwarrior]

13:33 for me, and my 8th puzzle in a row solved in under the video length! The break in is exactly what I thought it would be, and from there it was just a matter of coloring and entry. I really enjoyed this one. Another commenter pointed out there was a more efficient way to color, but I like the way I did.

[@AndyeKAA]

I was also so proud of me if i was doing any puzzle faster than Simon (maybe 3 in total), BUT we dont have to EXPLAIN it to others. I think Simon would do this in less than 10 mins without explaining...

Immensely gratifying puzzle. Thanks!

[@flatfingertuning727]

This puzzle reminded me somewhat of a meta-puzzle I saw on a different site: find the minimum number of cages required to give a cage-sum sudoku a unique solution, if digits are allowed to repeat within cages. The answer, somewhat shockingly, is one. A single (rather large) cage with a given total is sufficient to place all 81 digits in the grid, with no other clues beyond the fact that every row, column, and box contains the digits 1 through 9 once each.

[@springinfialta106]

42 has now been superseded by 178 as the answer to life, the universe, and everything.

24:43. Closest I've ever come to beating Simon, by a looong shot. Really an incredible puzzle.

[@johninnaperville]

Absolutely incredible. I saw the path to take immediately as only adding things up could possibly give a solution. The pattern of minimal double digits imposed on minimal digits in the boxes was simply genius setting. A really fascinating puzzle.

[@Ulija100]

I shared the three stages of disbelief: 1) on opening it and not believing it could be done 2) on reaslising the maximising/minimising did it 3) then exploring through a surprisingly smooth solve thereafter I'm sure others found this too, but my instinct was that 178 is close to 4x45. So after colouring I subtracted the four most filled in boxes to get difference of two coloured sets must equal 2 (with a single pair of double counting still). Possibly made it a bit faster both to extremise and to see route to solve, but ultimately equivalent for both.

[@chitraagarwal8259]

This was so delightful! There's no way i would have tried this puzzle if i hadnt seen that Simon did it in 25 mins.. Solve time of 30 mins coz like Simon a lot of times i just paused to admire how easily this flowed...

[@MattYDdraig]

15:29 Although very simple to solve it is a beautiful creation to find such an empty grid. Would make a great introduction to more complex puzzles where sinilar tricks leave "degrees of freedom" to be resolved.

[@DanielPass]

Great puzzle and not too complex a solve, but only because I made a spreadsheet of min/maxes per box and the double counts! Amazing to see Simon work it out on screen!

[@piarittersporn]

Astonishing indeed. First I thought that I could never solve it. But I was wrong because the magic 178 made the solving very comfortable.

This reminded me very much of Treasure Map by Jay Dyer, which you had on 25th of July. Where the minimum cells were on one large arrow and the total had to be deduced. I can't decide which variant I like better.

The one that added to 98 in the pill, right?

[@OlafDoschke]

@@raswartz Yes.

I first tried minimizing rows and columns but those minimal sums end up slightly lower than 178. It's very satisfying to find that everything is fully minimized and you can suddenly place a bunch of doubles and triples.

This is one of the most elegant puzzles I think I've ever seen

Once it got started, it only took me three tries to get it right. Got my book today. Shipped out quickly and got it in Canada within a week or so. Thanks for the speedy response!

[@crystalgehrt8861]

I almost didn't try this because it looked too difficult, but I was heartened by the video time and I'm so glad I gave it a try! It was super simple after yesterday's puzzle that it almost seemed wrong, but it was so interesting and such a fun and rewarding solve!

The First puzzle i saw the breakthrough immediatly.. nice

I would love to see Mark solve this puzzle. I bet he would fully Goodliffe every cell within 5 min. Simon, of course, will not pencil-mark if it can be avoided. 1:45 "fabulous" yes, that's a good description. The idea behind this setting isn't new, but I doubt it has been exploited so fully before. Brilliant setting; brilliant solution. And let's not forget to mention that a big reason people watch these videos is because of Simon's enjoyment as he solves (and also true for Mark). 8:00 Specifically, there are 48 highlighted cells, some of which are double-counted, so the average value is somewhere near 3.

That was fantastic both the sudoku and the solution

[@minetogiveaway]

Excited for this one!

[@indigorune]

21:32 !! One of my few solves faster than Simon! :P I loved this one. The logic was fun.

[@gabobravorodriguez220]

21:54 for me, thanks for the approachable

[@michielgerretzen9777]

One of rare moments I am proud of myself that I found the break in almost instantly (as the number 178 must mean "something"). Thereafter it became a matter of thoroughly doing "sudoku". Great puzzle!

[@57daysproductions]

I keep hearing "That's Me in the Corner" when going into shops and I can't begin to explain to my husband why I get so excited. Ironically, his name is Simon lol

[@Tempus0]

When I saw the puzzle and the solve time, I knew the minimal sum had to be 178. If it had a few degrees of freedom, this would quickly become a 2 hour puzzle.

[@ApesAmongUs]

I have watched so many videos that somehow I solve this as my first sudoku. 60:23 after a big rewind when I accidentally removed a 6 center mark in r8c9 instead of a 5, then looked and saw I could remove the 5 as well and thought the puzzle was way too easy until I hit that brick wall. The break in was really obvious - just knew it had to be highest or lowest.

[@masonzeagler5722]

I admire this a lot.

[@SpydersByte]

wow, went straight to the timebar after reading the rules expecting to see a good 2 hours and.... 25 minutes? The hell? Cant wait to see what kind of massive revelation allows him to do this one so fast!

[@darleneofthetallpines5742]

Approachable and fun!
