** TODAY'S PUZZLE **
The question of how puzzles end up with the ratings they do is a vexed and interesting one. Myxo's sudoku, Revolver, has perhaps the lowest rating of any we've featured on the channel. And yet... it is startlingly brilliant. All hail the CTC Testers who have unearthed another stunner!
Play the puzzle at the link below:
app.crackingthecryptic.com/su...
Rules:
Normal sudoku rules apply. Digits in a cage must sum to the small clue in the top left corner of the cage. Digits may not repeat within a cage. Every digit, except the digit in the centre (r5c5), has a 'partner digit' that is always placed in the cell 180° rotationally symmetrical to its own, rotated around the centre of the grid. Which digits are paired up must be deduced by the solver. (eg If the digits 1 and 2 turned out to be a rotational pair and r2c4 is a 1, r8c6 must be a 2.)

Myxo here :) What an incredible solve, seeing how much you enjoy the puzzle really brightens up my day. Thank you for the feature! ❤

@Myxo-hv4ov Год назад

I don't worry too much about the rating personally, but about the feedback I get from people. I've received a lot of positive feedback about this puzzle, but also a bit of negative feedback - the constraint just isn't enjoyable for everyone, which is fair! I think the main thing to take away is to give all puzzles a fair chance if they seem interesting :)

That final step resolving the seeming broken pattern is so pleasing

@Coldheart322 Год назад

I just know it would annoy me for ages if I was trying to solve it myself. Yet somehow I spotted it this time round. Definitely a nice finishing touch.

@bertbergers9171 Год назад

I have not spotted it, so i will have to watch on from 39:52 (where i finally had gotten enough clues from Simon to solve till the final broken pattern myself) to know what that step involves. And it will be a hard journey, since at 42:33 Simon puts a 4 in r6c2 where it is excluded by the 4's in box 4 needing to be in row 5. Hope it will not be the only rough sudoku. Okay that was a reasonable fast spot of the oopsie. I really was not smart today for not seeing that finish to the pattern.

@tomn1307 Год назад

I think he does it deliberately. If his voice were not croaky, we could assume he had recently been speaking and perhaps... had just switched over from a puzzle which he had failed to solve. As long as he is croaky, we can assume, as you say, that it has been some time since his vocal chords were in use.

@markbennet9058 Год назад

This is the kind of logic I look for in tough puzzles - something actually worth finding! If we did puzzles like this regularly some of the deductions would be routine, but this puzzle takes me, at least, beyond what I've seen before. Just brilliant - and clear exposition as usual.

@smylesg Год назад

In classic Simon form, he ignores the three-cell 10 cage in column 1 when determining if 9 (in the opposite 22 cage) can map to itself.

@AliceYobby Год назад

I was screaming the whole minute 48:00 for him to see that the 1 2 pair in the 36 cage was forced by sudoku because of the 1 above it. But of course he goes the roundabout way : ). Would love to go on a drive with him, I’d imagine I’d be shown quite a lot of scenery on the way to our destination

@randominternetguy3537 Год назад

@AliceYobby tbh, he did the puzzle 10x as fast as I would. So I would assume you would be hanging on your seat as he drove 10x the legal limit and enjoyed the scenery.

"Brilliant puzzle" are actually the same words I commented when first solving this puzzle a few weeks ago. I'm shocked it ended up with such a low rating, this is a puzzle deserving of much more acclaim.

Thank you Simon for the recommendation to pause the puzzle for the final deduction! It was very fulfilling to find that 15 pair via the rotation rule set.

What a stunning puzzle, and what an incredible ending. I've been watching CtC for nearly 3 years now (got randomly recommended right at the start of the pandemic). I think that's the first time I ever followed the encouragement to pause the video to see if I could spot the required step, and actually managed to do so. Thank you Simon for encouraging us to do that. Beautiful, just beautiful from start to finish!

Well done Amy for able to spot the next required step!! 😀 Between all the content and lessons we get from here, Zeta , Ransgk and Memeristor, have no doubt that you are able to deduce and see things!! Honored to have you be part of this amazing community with me. 😁

@amysteele2488 Год назад

@David Rattner, thank you! It's a wonderful community to be a part of. I'm sure those collaborative solves over on Zeta's channel are really helping my ability to see the next logical step

@alainculos9294 Год назад

This puzzle exemplifies why one should watch Simon solving. Personally, I can and I have solved this puzzle, but Simon invariably does so following a much more elegant path and quicker despite taking his time to both find the right logical step and the time to explain his thought process. While Simon misses the odd "obvious" step, I find his ability to zone in to the key ideas absolutely fascinating and outstanding. It also makes one think about rating puzzles. Indeed, if one were to miss, as I frequently do, the elegance of the intended solve path, then what does the rating mean? Maybe the puzzle pads or repositories should enable setters to publish their key solving steps to those who successfully solved the puzzle, so as to compare one's solve to the intended and appreciate the true worth of a puzzle.

@deniz5566 Год назад

If the worst has 86%, it only means it's more special to be honest. Can't wait to watch the rest. Greetings from a cold fresh night in Germany, Deniz :)

@Moolers Год назад

If 86% is the worst featured on this channel, then I want to know what a really low rated puzzle is like. It would be interesting if you found the lowest rated one and solved just to see if it was truly that bad.

@SnowTheJamMan Год назад

There was a guy on LMD called "CC" who posted absolutely terrible puzzles that would get around 25% each time, i think his account got removed cause it was found to be an alternate account of another setter.

@Chefofdeath793 Год назад

There was one a few months ago the had like a 20% approval rating. It was riddled with multiple rule sets and 99% of the clues weren’t needed and it had a lot of givens which made everything pretty much the easiest puzzle ever.

@chipsounder4633 Год назад

Yeah be a puzzle with 45 givens and have a ruleset like: in every row you must have a 0 sandwich

@Jellow2202 Год назад

Yeah, taking the worst puzzle by rating would be awful. However, I find the general idea somewhat intriguing... How about having constructors and/or viewers submit puzzles they think are unjustly rated. Then have the testers select one of those once a week or month for Simon or Mark to tackle.

@alainculos9294 Год назад

Yes, and include puzzles with low solve counts too

@_raumplaner6575 Год назад

The 'rotational pairs' constraint was developed by sirxemic, and I'm very happy that Myxo made this puzzle to showcase some of the cool logic. Edit: I was informed that the constraint was used in similar ways back in 2019. So sirxemic did develop, but didn't invent the constraint.

@kevinmahlendorf4955 Год назад

Poor Simon is increasingly forgetting Sudoku and focusing on the puzzle specific rules 😬

@Stettafire Год назад

I think that's Simon in a nutshell 😅 But that's why we love him 🤣

@stevesebzda570 Год назад

Yes, there's a bit of cuteness that Simon missed (due to this "sudoku ignoring"). Here (@44:03) [I had to follow along to just before that point] That "7" in box4 (because it had to be 10 in those outer cells), took the 7 out of that green cell in box1. [And being there was no 7 on that end, the 7 couldn't be symmetrical to itself on the other end in box9. ] So, they're a "69 pair." Now you have a 69 pair looking at the converging cell in box3 (R1c8). [The 9 was only in three places up there] That puts the "9s" vertically in col7 of box3 That takes the 9 out of two cells of that "green in box9" and actually places the "9." [It fed back into itself in other words -- nice] Which placed a "6" symmetrically up in the green in box1. Simon would have liked to have seen that [A precursor to that ending pattern] He's gotta pay more attention to "sudoku," I agree. He would have liked to have seen that lol 😂

@stevesebzda570 Год назад

[You're seeing it now though, Simon. Enjoy lol ]

@nonagrey3422 Год назад

This, quite frankly, is a brilliant puzzle!. Well done Myxo!

@jeythegrey Год назад

@ 39:45 I think you can prove that this cage is a yellow 10 cage through the deduction you made one step before (which makes it a bit easier to see). You ruled that the 7 is in the 36 cage, placing a 2 in r5c7 and c8. This placed the 2 in box 5 at the bottom left 2 cells in the 11 cage. Thereby ruling out a 2 in r6c2 and forcing both 2 and 1 into the triomino shape of the 18 cage in box 7. Therefore, the counterparts of 1 and 2 (5 and 4) are placed into the rotational partner 10 cage in box 3, proving it to be a 1,4,5 cage

@zach31194 Год назад

If you slightly tweak the logic, Simons proof by counter example is more powerful. Because there is a 1 in the rotational counter part to that 10 cage, it must have a 5 in it. So it’s either a yellow 145 cage or it’s not. If it’s not, it’s a 235 cage. Which based on the logic shown by Simon in the solve, is not possible. Therefore I HAS to be a yellow 145 cage. QED

@Kursonkel Год назад

@zach31194 I disagree. The logic presented by @JeyTheGrey does exactly that, only with fewer steps. It forces 2s in the same positions as 1s in box 7, therefore forcing the 10 cage in box 3 by fixing two of its three digits due to the rotational counterpart logic. It's a classic Simon using more complex logic than needed.

@salionshatterstar Год назад

Nice! I came to scan the comments to see if anyone else had noticed this. Provides an extra drop of elegance to the solve.

@bertbergers9171 Год назад

Thanx for the puzzle Myxo! Great solve Simon, few sudoku hick-ups, but nothing too upsetting.

@carlpantuso7718 Год назад

Agreed. Brilliant puzzle and extremely fun to solve and even more fun to watch Simon solve. And the ending is superb!

@MaierFlorian Год назад

What a beautiful ending. I guess some people don't like it because the ruleset is quite hard; after you found the mapping pairs you have to remember and use them, just to find out over and over again that you could have done that particular step with just sudoku. But very original and fun to watch :)

@martingriff101 Год назад

For some reason and maybe it was due to the example in the rules I was going crazy with Simon thinking the partnered cell was a consecutive digit

@stangerrits6712 Год назад

What a sensible use of coloring today from Simon 😊 Very nice finish as well!

@Gonzalo_Garcia_ Год назад

24:44 for me. I feel like I understand the low rating on LMD, this kind of constraints get a little bit repetitive too quickly (at least for me). However, I think it's a very nice idea and I did love the break-in.

@fe1999 Год назад

“That’s about as useful as a chocolate teapot” absolutely sent me

@Samhain_III Год назад

This logic is perfect for people with poor scanning ability (like me) as all possible logic is represented twice! (Once for the digit and once for the rotational counterpart) This also reduces the overall number of digits you need to find by nearly half (excluding the 7)

@MatthewBouyack Год назад

The trick at 37:16 was exceptionally clever (especially the reflection from r7c7 back to r3c3 determining the 10-cage). Whole-heartedly agree with Simon's assessment of the puzzle as "absolutely first class"!

@dakotasherman3813 Год назад

This puzzle is the exact reason I never look at reviews/ratings on movies, games, puzzles, or anything else.

@glum_hippo Год назад

Brilliant puzzle by Myxo, yet again! I do think the LMD rating system is not a great metric… there are puzzles with very few solvers in which the opinion of a handful of sudoku haters can severely drag the raw percentage down and convey the wrong impression. I don’t want to presume to tell you what to do as you’re definitely doing something very right… but if you get a recommendation from a voice you trust, and your testing team gives a puzzle high marks, then I believe the LMD rating can be wholly ignored.

@bobfish7699 Год назад

4 1/2 out of 5 is a pretty good rating. Not everything can be top marks else the rating system becomes meaningless

@danielprivett6155 Год назад

16:25 When you say things like "these two digits would have to add to minus 4" I just immediately imagine a setter hearing this and thinking it's a great idea for a new variant. It's the Schrodinger's cell puzzle all over again.

@Coyotek4 Год назад

53:55 ... actually a couple minutes more, as I paused wondering why I saw multiple solutions ... before seeing the very thing Simon pointed out at the end of the video Nice puzzle!

@jonatansverdiolas486 Год назад

My solve took so much longer! The idea of having two numbers summing up to 9 not being in the 7 cell domino is simple but brilliant

@ronjohnson6916 Год назад

Any puzzle that makes Simon chortle after a deduction gets bonus marks. Also, this is Simon in his element. Very much a nod along solve for me. I can follow all of his explanations, but ... I fear my solve would be a couple of hours of bifurcation.

@stevenberge5481 Год назад

I had a rare "yelling at the screen" moment for this puzzle. Simon spends a lot of time at the start trying to decide whether 9 can map to 9. But he could have realized this is not possible much sooner by considering the 22 cage in column 9. It maps to the 10 cage in column 1, and of course a 10 cage cannot contain a 9. Otherwise, excellent solve and very cool puzzle!

@yichen6313 Год назад

Lovely idea. I think this has the potential to be much, much harder.

@srwapo Год назад

94:01, I couldn't do this one without looking at parts of the video. I wasted 15 minutes treating it as a mirror about a diagonal instead of rotating 180 degrees, and I kept trying to do that throughout. The break in logic was neat and a bit above my ability, some of the other logic was "try and prove it fails" on my end.

@johnh2052 Год назад

At 34:00, Simon examines the fact that it is difficult to put a 5 in the 36-cage. He sees there is a way. and moves on. The question to ask there is: what if there *isn't* a 5 in the 36-cage? If no 5, then no 4, either. And this would mean no 1 or 2 in the orange 10-cage, which is impossible.

@57thorns Год назад

25:40 I believe the 1 has to map to a 5 or an 8, so there is either a 1 or an 8 in the top right ten cage. And it is certainly not an 8. So by know we know these: 9 is mapping to 6 or 7. The other of 6 or 7 is the solo digit, 1 and 5 maps. 1 and 5 mapping means the 10 cage in box 2 is 154, giving us 24 as a mapping. Not sure why I felt the need to point this out, but just in case Simon finds something more complex I guess.

@kurtu5 Год назад

It's really cool when the last deadly pattern is solved by logic and not just sudoku. It must take some small genius to keep a puzzle from devolving into just a standard sudoku towards the end.

@Raven-Creations Год назад

You could immediately tell that 9 does not map to itself (or 8), because neither 9 nor 8 can go in the 10 cage in C1. The cageless cells in box 5 sum to 22, so include 9, and since the 9 cannot be in the centre, it must map to 567. If this is a 985, the 9 maps to 5 and there's an 8 in the centre. If it maps to 967, 9 maps to 6 or 7 with the other in the centre. This gives you 678 in the centre, and 5679 in the corners. If you pencil-mark where 9s can go in the grid, they are quite restricted. This allows you to rule out 9 from R8C7, because that would put the 9 in the mirror cage in R1, forcing 9 in box 3 into R3C7 where it clashes. I loved the finish, which was one of the best I can remember. It did appear to be a deadly pattern, except that R1C4 and R9C6 were a 15 pair, making R1C6=4 and R9C4=2. That the pair rule should resolve the pattern right at the end was a treat. This was a really nice puzzle, worth a much higher rating on LMD. I kept being surprised by it, with new deductions popping up apparently from nowhere.

@stevieinselby Год назад

I think it's absolutely fine to rate a puzzle even if you don't think you found all the logic. If a puzzle has some complicated, esoteric logic required for a break-in and it isn't sufficiently telegraphed to be findable then the puzzle isn't an enjoyable one to try to solve. For my money, those puzzles are less likely to interest me because it's unlikely I will be able to solve them. A difficult puzzle doesn't necessarily make a good puzzle!

@Nevir202 Год назад

39:55 we can immediately see that it can't be that. as the 7 in boxes 6 and 9 are both in columns 8 and 9.

@revanbrummel8828 Год назад

I thought: the two gets knocked out of box 3 because of the middle box. So there´s 1,2 in which means in the 10 cage in box 3 there is 4,5 in with a one.

@@revanbrummel8828 I struggled to understand this comment until I realised you probably meant the middle box knocked 2 out of box 4, not box 3. (At least, I assume that's what you meant?).

@FrancisFjordCupola Год назад

I do not think it would be fair to judge a puzzle only when _all_ the logic of the setter is uncovered. Why? Because I have seen Simon, bless his intelligence, looking over the most obvious pieces of logic. The reason seeing that is enjoyable is because Simon usually does spot almost all the other difficult logic and seeing something Simon does not is therefore rewarding. Might have been obvious, but we beat Simon to it. To get back to the other point, even Simon misses logic of setters. I think any judgement is subjective in nature any way and it greatly depends on the people who attempted (and perhaps succeeded) to solve a puzzle.

26:40 - I thought about something different. if you map 1 and 2 into the rotation of the 10 cage 2 digits in there would come from the 22 cage, even if you didn't knew what was in there, the 3rd digit on the 22 cage would have to be a 13...

@RichSmith77 Год назад

I thought it was even simpler. We already know it's the 9 that maps to the hypothecated 7 in blue, so that leaves 5&8 mapping to 1&2 in blue. That instantly breaks yellow.

Oh what a frabjous puzzle! I spent 1:14:09 on it - of which a goodly 10 minutes on the last wrinkle. I *could* have solved that by simply ticking off the possible combinations but I did *not* want to do that. It would have been like the desecration of a work of art. It occurred to me that the absolute differences of the four pairings would make the rotationally symmetrical cages with wildly different totals *and* those with very nearby totals difficult - i.e. the 10 vs 22 cages and the 11 vs 12 cages - as it was, the 7/7, 2/4, 6/9, 1/5 and 3/8 pairings have deltas of 0, 2, 3, 4 and 5, but I did not know this beforehand, obviously. Therefore I played around with various ways of combining sums and differences of various possible deltas to account for the difference of 12 between the 10 and 22 cages. I made things *far* too complicated for myself and abandoned this line of reasoning and forced myself into Simon mode, wondering what sort of questions he would ask. Then I found the break-in, and it was exactly Simon's break-in. How much I hae learned from CtC - and not only variant sudoku techniques... And: Myxo, take a bow! You, my friend, are an artist with impeccable taste.

@Freeeez3 Год назад

i think the "low" approval rating is partially because people get stuck on the final pattern with the 1-5s.

@nonagrey3422 Год назад

@mewmewmew12 Год назад

You could also get that 9 doesn't map to itself in the beginning by noting that the 9 in the rightmost 22-cage can't map onto another 9 in the leftmost 10-cage

@OlafDoschke Год назад

54:57 I totally agree, but I solved this already and only watched how you solve the end. For me the pleasure was that a) you had the same "end game" and b) I solved it differently. You can see that a 1 in row 1 means the 1 in row 6 is in column 5 and the 180° rotated cell in row 9 would also need to be a 1 by sudoku rules but must be a 5 by pairings. So r1c4 is not 1 but 5. And then the rest follows. I have to admit looking at cells r1c6 and r9c4, the cells which see the 15 pair and therefore can neither be 1 or 5, no matter where the 1 and 5 of the 15 pair go is a bit more professional to solve this situation.

@RichardDamon Год назад

I think you may be right about why it got a low score, if it gets "too hard" to logically solve, it succomes to "guessing", which makes it seems not that good.

@RobertGardnerEngineer Год назад

My solve on that last trick was different. I said "what if I put a 1 in box two top left, what happens" if you do that, you can't put a five anywhere in box 2, therefore it must be a 5. At that point the puzzle resolves.

@xtremegohorse Год назад

I see people criticising Mark for doing bifurcation. With all due respect, how is this not bifurcation? It falls every time in a "if this, then that... no, it's not, so it's only that one". It's not a full bifurcation, but there are several bursts of bifurcation in every Sudoku I've ever played. Other than that rant, brilliant as always. Never could done that myself :D

Is the game they've been streaming really pronounced "TAY-zhee"? I keep hearing it pronounced this way on the channel but wouldve assumed it was tie-JEE like the Chinese philosophy (and closely related to the martial art usually called Tai chi, or Taijiquan).

@marklindsey1995 Год назад

"The worst puzzle" There are some folks (very well known) who use computer software or use other solvers videos to get a solution to "solve" a puzzle and then put in the lowest rating possible. If @CrackingTheCryptic is using ratings to determine a puzzle's worth, they may be doing themselves a disservice. This is why I try to make my puzzles not computer solvable (for instance, I will replace the German Whispers constraint with a cosmetic green line) . Unfortunately, as a result, very few of my puzzles get rated. I hope they get to see this comment.

Very surprising feature today, as I will completely admit, I have contributed fairly on that low score on this puzzle. For me the constraint, while having a beautiful opening, led to the puzzle having a fairly tedious end solve. I am intrigued to watch this puzzle and see how Simon fares and thinks about it!

@Stettafire Год назад

It always fascinates me how some puzzles flow so naturally and others sort of stall in the middle. I'm curious of that's the case here. I shall watch and see

@DeborahJLeslie Год назад

The ruleset is fascinating and this is indeed a clever puzzle, but it falls short of brilliant--and probably deserves its LMD rating (had nothing to do with me). Trying to articulate to myself how it fell short, and what comes to mind is that it's 'flat'. No real break-in (Simon doesn't get his first digit until 27:22); no logical flow to the solve. I'd love to see this ruleset constructed with a solve path in mind. (Said kindly enough, I hope.)

@themorebeer3072 Год назад

I suspect this puzzle is rated low because a significant number of people couldn't figure out the logic and had to resort to guessing. If they have to guess to solve, they never see the logic that makes it a worthy handcrafted puzzle. It could be that this style of puzzle could benefit from more contextual cues to lead people to a logical solution path.

@draquillin Год назад

Simon's observation at @51:40 that he's just doing the same sudoku on the other side and not progressing the solve might be why it has its lower rating.

@-42-47 Год назад

Yeah it's a great puzzle but my brain seems to be incompatible with the symmetrical partners rule, something I think might be a common issue among solvers.
