▶ NEW SUDOKU PUZZLE HUNT JUST OUT ◀
You can find our brand new sudoku hunt on Patreon now! Can you unlock the secrets of the Wonders Of The World?!!
/ crackingthecryptic
*********************************************************************
Today's puzzle looks completely impossible! It's by Mesmer and it's really rather wonderful. You can try it yourself here:
app.crackingthecryptic.com/su...
Rules:
Normal sudoku rules apply. Digits cannot repeat in a cage. The value of a cage is the sum of the digits it contains. The value of any cage must appear only ONCE on the board. Eg, if a cage value is determined to be 15, there is not another cage with the value 15. The inequality sign is pointing to the smaller digit of the two cells. The cells on the diagonal pointed to by the arrow sum to double the value of the cage marked with X. Digits can repeat on the diagonal.
▶ SIMON VS PHISTOMEFEL ◀

I figured out what the break-in would be almost immediately just from the ruleset (mainly just because of how many of these puzzles I've watched, I'm wise to the common tricks by now), but when I realized that actually doing the puzzle would involve keeping track of which cage totals I'd already used, I chickened out and decided to just watch Simon do it instead.

The amount of raw information you can keep in your head is amazing.

There's simply no way I could keep that all in my head and continue in my stride.

@oisyn- 2 года назад

So much this. I solved this puzzle myzelf after watching Simon for a couple of minutes, but I used notepad to keep track of all the cages I already found and I had permutated all possible digit combinations for each cage, which I then stratched off after it had become clear some were no longer possible. I would've completely lost track without my notes.

Since you asked for an easier way to disambiguate the 16 cage: Once you narrowed it down to two cages at 49:26, you know R7C4 can't be a 4 (because the 16 cage needs a 4). This means that R9C4 is a 4 and the cage in R9 can't be the 16 because R9C3 can't be a 5 or a 6. I loved watching this. You're very entertaining and a great teacher at your thought processes.

@Crocodile_Appreciator 3 года назад

Proud of myself for spotting this: Simon figured out early on that the 56 in the red cages was a pair. That means that the 56 in r5c1 must be the same as the 56 in r6c9. So r4c6 must be the same 56 because it's the only cell in that box that doesn't see those identical cells. Later, he rules a 5 out of r4c6 using the 57 pairs above, making a 6 placeable early on in a few cells at once. Not sure if that unravels the puzzle better than Simon's logic without it, but it helps!

@Draddar 3 года назад

Nice one. This or the 23 cage logic Simon did was the part I couldn't get through. Your's seems a lot cleaner to spot during a solve.

@jamese4336 3 года назад

You're right. It allows you to realise that the 6 in box 9 is in column 8, which then puts a 6 in R1C7, a 3 in R1C9 and R7C7, then an 8 in R7C8 and a 6 in R9C8. we can use this 6 to confirm that the box in row 9 isn't the 15 total. Great spot.

On ~52:05 there is an alternative way of getting "6" in (4th row, 6th col). There is a pair of (5,6) in two red cages. They are different because of sum. Also in the first column there is an intersecting pair of (5,6). Which means that the cells marked with (5,6) in (5th row, 1st col) and (6th row, 9th col) are equal. By sudoku the same equal value in the middle box should be in 4th row, but there is only one free cell that can't have 5 in it = all of those 3 cells are "6".

mind is already blown by all of the math he is doing in his head before we even put a single pencil mark in... some people really are just built different

@TommyT067 3 года назад

Even if I played this video at the slowest possible speed, I would still not be able to catch up with you. You are a mastermind Sir!

@andrewzywicki2745 2 года назад

I got into watching these videos because the sound of Simon's voice and keyboard are super calming, and help me relax. I have even fallen asleep to a few, but I have to say that I was intently watching through this whole hour! Amazing solve, and amazing puzzle.

@violetasuklevska9074 3 года назад

You know Simon has been giving Mark a hard time, but the Goodliffe pencilmark for the greater than sign has actually prevailed near the start of the puzzle. Still trying to solve, but a fun remark down the road nevertheless.

@AGMS594050 3 года назад

Has to be one of the greatest puzzles I've seen, up there with the best for pure beauty and flow.

@Sarahr98998 Год назад

This was fascinating. Never thought I'd make it through the full hour, but I was hooked!!

@charleslynn7420 2 года назад

This is the second video of yours I’ve seen and this the second time I’ve ever considered that people would set extra rules for a sudoku puzzle and my mind is utterly warped trying to wrap it around this puzzle. What a joy to watch!

@ryang4335 3 года назад

That was such a joy to watch! The hour honestly flew by. Great logic, loved the concept and you did a great job keeping up with all the different totals - brilliant!!

@livedandletdie 3 года назад

That was one profanity of a puzzle, truly astounding.

@SourceOfBeing 2 года назад

8:20 - A way to find the sum of numbers in the sequence "1, 2, 3, ..., n-1, n" that I find easier is the formula "(n*(n+1))/2". So in this video, that would've been (24*25)/2 = 600/2 = 300.

@fybso3057 7 месяцев назад

Every couple of months an even crazier video of you gets swept into my recommendations. Delightful

@danielrhymer1762 3 года назад

47:12 to solve! Enjoyed that a lot with it being very maths heavy. Got the general break-in almost immediately and was then able to slowly pluck off the totals from low to high 😃

@Sujisan4 3 года назад

That's got to be the best intro to a video that I've ever seen.

@glum_hippo 3 года назад

Excellent puzzle, it required some real sleuthing! Took me 74 minutes I think it's rather amazing that this is not only solvable, but it's designed so that you can just about do it without having to keep track of the elapsed cage values in a notebook... since you have to find the extreme values and work your way more or less to the middle. Gorgeous!

@emmmaplays 10 месяцев назад

i love how half the comments are people amazed with this skill, and the other half are people surprised that they are still up at ungodly hours of the night watching a british man solve a sudoku puzzle

@Draddar 3 года назад

Nice puzzle. I feel despite the video length it's quite solvable for the most part. The break in isn't awfully hard considering information we are given and then just have to go through it systematically and keeping up with all the cage totals. Only really got stuck at the 15 cage, after that it's again doable - slowly but surely.

@danielrhymer1762 3 года назад

Agree having solved it. The break-in is fairly intuitive if you’ve done CTC puzzles before. After that, I found the hardest bit was probably keeping track of the used totals

@shakeslm6978 3 года назад

Makes me so happy that simon, by all regards a brilliant mind, also has to remind himself and work out an inclusive range. That is something that has just never worked for my brain haha 5:30

@66Morti66 3 года назад

Man that one was tough. I had the idea with the 2 remaining cells rather early, but disregarded it immediately, because I thought that this would be too insane and I didn't want to do the calculation in my head. Took me 30 minutes to return to this idea, but oh well. Took me 93 minutes total, very nice solve by Simon. :) As a side note, to quickly sum up all the digits from 1 to n you can use (n*(n+1))/2, in this case it would be 28*29/2 = 406, from which you still have to subtract the missing 1+2 cages.

@MortlachNL 3 года назад

Just got an internet upgrade and now have a blistering 25Mbps connection. Can confirm Simon is just as entertaining and witty in 1080p as he is in 360p. Puzzles are still as difficult though and I am starting to worry I might have been a little cocky when I backed the Kickstarter Sudoku book. They do say the Overconfidence is a slow and insidious killer...

@100greggyt 3 года назад

What a puzzle! Was able to solve it in 90 minutes so definitely wasn't easy. Possibly my best solve to date without taking any hints from Simon or Mark.

@FetnerVideos 3 года назад

I was able to solve it in 100 minutes, but only after finding myself with a messed up puzzle after 140 in my previous attempt. And I also feel it is my best solve. This one and the thermo tree are my two favorites that I solved from the channel.

@JaymanOttawa 3 года назад

This is my favourite puzzle break in to date! And that is saying something considering all of the amazing puzzles featured on this channel. I sure hope I can finish solving it... :)

Love watching your videos. You do a great job of elaborating on your thought process. It’s an absolute thrill watching you piece together puzzles that turn my mind to mush, and I’m almost on the edge of my seat calling out the next moves you make as you put everything into picture. Love your stuff, please keep it up!!!

@mercut10 3 года назад

24:15 day two of either 3 keeping his religion, or Simon forgetting to announce it 😢

@billbliss7407 3 года назад

10 seconds in, and I'm already laughing! Thank you Simon!

@Astroweasels 2 года назад

I'm so glad he said deadly pair at the end because I did not know what the word was for it. I had recently installed Sudoku on my phone and I kept encountering those and getting mad.

@MrsGov85 3 года назад

Your shock in the beginning when you realised you would have to add up all of the cages to figure out the 2 lonely cells had me cracking up, your reaction was genuinely funny - but then you found the easiest way to do the math! Completely amazing!! I always learn something watching your videos :)

@bristolrovers27 3 года назад

Great introduction Simon in his element although he had to resort to sudoku at one point I’m not sure if I guessed the disambiguation of the 5 and 7 in row two much earlier than Simon or it was startling deduction !

@debelaysek 3 года назад

I will never understand why thumbs down for masterpiece like this. Fantastic puzzle and solve. Just beautiful.

@Graknorke 2 года назад

the "pairing off" you were doing to figure out the sum of the cages is attributed to Gauss, very useful for finding the sums of algebraic series

@FetnerVideos 3 года назад

Solved this after a combined 4hrs. First 140 minutes led to a messed up puzzle, which I restarted and then it took another 100 minutes to complete. And you know what, I'm proud of myself.

@anneharrison1849 3 года назад

I did this without assistance, which makes me super happy seen as it took an hour.

@simonlundin97 2 года назад

This is so damn impressive, the way you explain how you are thinking giving us the "ahaaa" moment just makes these videos so amazing to watch!

@beeble2003 2 года назад

To do the digit summing around 8:20 with less thought, the sum of the integers 1, 2, ..., n is n(n+1)/2. This is closely related to the pairing-up argument that you use (you can see that in the n+1), but a faster way to see it is that you're summing up n numbers and the average of those numbers is (n+1)/2, so the total is n(n+1)/2.

@petermarckmann9046 28 дней назад

These videos are always kinda weird because you find something before him and yell it at the scream and then he finds something you would never find and you’re like: “I back down again”

@scruffamudda6306 3 года назад

My word! Took me 3 hours (without any help from Simon) but I did enjoy it. What a puzzle!

@anneharrison1849 3 года назад

my timer says 100minutes, but I did go to the loo and have a drink...

@jamese4336 3 года назад

42:21 for me. I wouldn't have been able to solve it without watching previous videos. It gave me the courage to work out how the restrictions worked on the puzzle as a whole and to build up through the puzzle. Now to spend another hour on the solve video to see whether our solve paths matched. 😀

@jamese4336 3 года назад

Very similar paths at the start. At 24:50, you can go further with the 4s as you can rule it out of the length 4 cage in box 3 At 27:00 you can place the 4 and 5 in row one by considering the possible totals of the 4 cage in box 3. At 30:00, I just started going up the cage values without worrying about tricky sudoku deductions until I got stuck, which was hard work, but paid off and probably was a bit faster. One thing I spotted is you can look at 3 totals in a row as 6,7,8 need to contain a 1. 9,10,11 need to contain a 1 or a 2 etc. 41:30, that's how I was feeling for half the puzzle. 47:44, I broke through by considering what could be a 16 or 17 as they also need to have one digit at most 4. The R6C7,R7C7,R7C8 box can't be a 17 as you end up with a 6 in R6C7 and a 5 in C9 in box 9, invalidating the 56 in R6C9

@s.owl9 3 месяца назад

This makes me feel so smart 🥰. I only came to understand Sudoku yesterday by watching on of your “impossible” Sudoku puzzles (one similar to this one with cages and only a 2 on the bottom left square), yet Im able to easily keep up with you as you explain and sometimes even think of solutions moments before you do. It’s (usually) a game of patterns, not math, which means it’s right up my alley in terms of ability & motivation. This one was harder because Im too lazy to do math, but I understood the math when you explained it and was satisfied when my early assumption, about the 2x diagonal being a late game clue to finish the puzzle, proved to be correct.

@jaredpearce4244 2 года назад

By the time I've solved the first clue, he's on "Now where is box 14...." It amazes me how he kept that all in his head without a notebook or a psychiatrist.

My brother and I solved this together after 3.5 hours. its amazing that our solution and reasoning is almost exactly like yours. There really is only one path through these puzzles
