** OCTOBER MONTHLY REWARD - OUT NOW **
The Duality Sudoku Hunt was released yesterday. Massive thanks and kudos to the Sudoku Skunkworks for creating such a brilliant set of puzzles (14 in all). You'll be able to enter the competition if you can solve the first 4 sudokus. If you solve all 14, you'll get a shoutout.
We've also just released Simon & Mark's solve of Vignettes by zetamath, which you can play at the link below:

** TODAY'S PUZZLE **
Mark sends Simon through another of his prank sudokus today with Chameleon's Quantum-safe Sudoku. This is absolutely bonkers. The idea is that you cannot solve it (!) but figuring out how to not solve it is... quite hard!!!
Play this extraordinary "sudoku" at the link below:
app.crackingthecryptic.com/su...
Rules:
Normal sudoku rules apply. Cells separated by a black dot must contain digits in a ratio of 1:2 (ie one digit must be double the other). Cells separated by a white dot must contain consecutive digits. Not all possible dots are given. Cages are “Schrödinger cells” ie they contain one of 2 values. After filling all regular cells with digits, all Schrödinger cells must remain unresolved (in other words, both values of every Schrödinger cell must allow for a valid sudoku solution). The quantum balance of the universe is safe with this sudoku. Cats are safe too.
[Note there is a tiny change to the rules above vs those which Simon faced in the video. We used "allow for" rather than "lead to". We do not think this will affect anyone's solve at all but we just thought it might clarify one tiny aspect of the puzzle.]
** GET OUR NEW FREE APP AND/OR WATCH US STREAM IT **
To celebrate achieving 500k subscribers, we're trying to say thank you in a couple of ways.

@chameleon_yura Год назад

Thanks so much for solving my puzzle! I didn't even hope for it to land on the channel. Clarification about the interpretation of the rules: it's totally ok to have multiple "deadly patterns" at the end ("both values of every Schrodinger cell must lead to a valid sudoku solution" doesn't mean that the puzzle must become unique after putting a digit into 1 Schrodinger cell).

@aikiseppuku Год назад

Don't understand why Simon is playing so dumb. Even after having drunk some wine, the rules are pretty clear and easy to understand

@MisterNohbdy Год назад

I don't check Logic Masters very often, but I'm glad I randomly did last week when this was posted. Brilliant puzzle.

@XPDolphin Год назад

I was just coming to comment that the rules say valid solutions, not only two valid solutions. Given Simon's solution, it seems there are 4 valid solutions resulting from this. Truly amazing. Good work.

@jesperwillems_ Год назад

The wording ‘must lead to’ does heavily imply that by filling in a cell it automatically gets you a solution. Luckily this ‘misinterpretation’ of the intended rules doesn’t break this wonderful puzzle, and with a finished grid in front of me it did become clear what the intent was; but i must agree with that wording it “must allow for a valid solution” does take away this ambiguity

@UltraLuigi2401 Год назад

Perhaps change it to "both values of every Schrodinger cell must lead to _at least one_ valid sudoku solution" to avoid this confusion.

@yerel_nimni_avni Год назад

It's not a deadly pattern but rather it's both deadly and lively pattern until you open the box.

@dominikbeitat4450 Год назад

I've just come to realize that watching Simon solve this puzzle is like watching someone fall in love. You don't understand what's going on, most of the time you think you're doing it wrong, never does anything seem to make sense. Yet you're mesmerized and terrified the whole way through, and while you've only figured out half of it at the end, the remaining ambiguity is the most beautiful thing you can imagine.

@simonbergqvist Год назад

I did it with colors. Wasn't bad at all. I would actually say that the visual helped a lot to see in which lanes you couldn't put certain numbers/colors.

@AlonAltman Год назад

This puzzle is a really good way to brush up on your group theory. While a pair (AB/AB) and triple (AB/BC/CA) have only one way to mix them without set points, 4 cells can consist of either: AB / AB / CD / CD (two 2-cycles) AB / BC / CD / DA (one 4-cycle) This does mean that if you know 3 of the pairs you can always figure out the 4th one. 5 (e.g. row 4 of the puzzle) is can be a 5-cycle (AB/BC/CD/DE/EA) or a 2-cycle and a 3-cycle (AB/AB/CD/DE/EC). 6 can consist of 2x 3-cycles, 3x 2-cycles, a single 6-cycle, or a 2-cycle and a 4-cycle.

@technoneko8108 Год назад

Well put

@henkkamerman1920 Год назад

Thats exactly what I was thinking. Simon at 1:13:00 puts a 36 in row 4 because he sais there needs to be one. But if I see it correctly, the row could have a 5 cycle which Simon did not think about: 23567 for example: 23/26/35/67/57

@kelperdude Год назад

Simon, here's a tip for you. When you gave out the link to Sven's channel, I went over there and asked him how to deal with showing clues outside the box, such as sandwich or diagonals, as being 'used'. His suggestion was this: Try using the pen tools and placing small crosses on the outermost edge. You even have multiple colours to use!

@heart.9889 Год назад

That works great, i've been doing that! Generally the pen tool is great for adding information to the grid!

@RoselynTate Год назад

I've already been doing this -- it works a treat, because it doesn't cause confusion for other clues within the grid

@AFastidiousCuber Год назад

Here's a weird observation: This Sudoku variant might be computationally harder than other variants of Sudoku. Most Sudoku variants, like classic Sudoku or killer Sudoku, are in the NP complexity class, because proposed solutions can be verified quickly. Whereas here it seems highly nontrivial to determine, in a proposed solution, whether each option for every Schrödinger cell yields a valid grid.

@keejay98195 Год назад

it’s still easy to verify by trying out both options for each cell

@AFastidiousCuber Год назад

@@keejay98195 Not necessarily. Once you place one digit, the rest of the grid becomes a classic sudoku, which is itself NP-complete to solve. Of course though, we're talking about generalized n^2xn^2 grids. If you went through every cell and tried both options, using standard algorithms to solve the resulting grid, it would take exponential time to verify.

@@AFastidiousCuber gotta have a think on this, what complexity class do you think this would be in?

@andrewcook8093 Год назад

The way to think about the shrodinger cells is that in each row, column and box you need to split them into cycles. A pair being a length two cycle. So a column with four schrodinger cells can be split into two pairs(pairing the digits up)or one length 4 cycle.

@columbus8myhw Год назад

And a length 4 cycle looks like [AB][BC][CD][DA] in some order. A consequence is that each letter appears exactly twice.

@wariolandgoldpiramid Год назад

This puzzle was just absolute madness. Got easier towards the end though. The beginning was such a crazy Matrix Metaverse, that I wasn't able to fully follow along Simon's solve, and just had to trust that Simon knows what he's doing. But as the solve progressed, I was able to get an understanding of what we're doing, and even yell at the screen at the "obvious pencil mark" clues Simon was, as usual, not noticing. Brilliant puzzle, Chameleon. And amazing brain power on your part, Simon.

@stevel875 Год назад

Although I didn't attempt the puzzle this time, one observation that would have helped during the earlier part of the solve is that each schrodinger digit must appear exactly twice in each row/column/box. Simon was entertaining the idea of having (e.g.) AB AC AD in the same column which is not possible as having a third A means that at least one of B C D must be restricted to a single cell.

58:30 This is the laugher found in the happiness of madness. Just under an hour to work out a way to APPROACH the actual solving of the puzzle and find the internal logic needed to work a solution. There is a reason the line between genius and madness is so thin. I foresee a lot more puzzles with Schrodinger cells so really the software needs an update where you can show them with something like (1~4), meaning the cell is 1 AND 4 at the same time and not that is 1 OR 4 like a normal 14 notation means and for the software to be able to validate if the solution is correct or not. Not an easy task but doable with the right thinking. Thanks for the video Simon, hope your sanity has recovered.

So, let me start by saying that "mental" does not begin to describe this puzzle. I could not understand what was going on for ages. Ages. At some point you began to figure out what happened in column one and I began to think that I understood what was going on - but no way in my lifetime will ever be able to do this. Maybe in heaven I will understand this! But YOU, Simon, are just amazing ... I was going to say "as always" but this goes beyond any "always" I have yet experienced on this channel. I will now also add that, were this the very first video I ever watched on this channel I would have been very, very puzzled. This was least like sudoku as I knew it before being directed to CTC by my son that I have ever seen. So anyone who is new-ish to CTC and variant sudoku, this was not typical of what usually happens in these videos - this was beyond the stars, beyond the end of the galaxy in its complexity, and even the most complex other videos on this channel are much more like sudoku-as-we-know-it (do you hear the echos of Star Trek: TOS in that?) than this. You will love it here - come back again and again and you will find so much to delight you. And then, after a month or two, come back and watch this again, and you will get it (much better than I do) and will marvel at this poetry-reciting, guitar-playing, genius of a solver, Simon Anthony, and be so glad you discovered him and this channel. (And of course I am probably just revealing how very non-brilliant and non-genius I actually am by saying all of that - but I am entirely right about this channel being one of the very best and most interesting places to hang your hat on the whole internet.) Kudos, Simon. I take my hat off to you - take a bow!

@sondang2412 Год назад

56:18 I think an easier way to put the 2 in box 1 is that C has to be in r2c3 because there's an X-Wing of C in column 1 & 2. Then we can deduce that C cannot be 4 because if it's 4 it'll eliminate candidate B from r2c2, which breaks the Schrödinger-ness.

36:00 Simon might it be time for Mark to solve a Phistomofel live and opened on camera?! Congratulations Simon on finally having the bravery to put up a solution to a sudoku you claim to have solved, yet you have left many of the digits unresolved! 😁🙃 Enjoy your bottle of wine with the live stream this evening, you have earned it.

@markp7262 Год назад

46:37 finish. What an absolutely incredible idea for a puzzle! I was going to talk about the X-wing on Cs, but it's already been mentioned. I wound up coloring the different Schrödinger cells, giving the ones in columns 1 & 2 dual colors (everything else was able to be a single color). So much fun, brilliant!

To construct this, Chameleon really thought outside of the box, to realize he/she cannot know what is in it.

@janeflett4971 Год назад

Thank you, great puzzle, I did use a bit of trial and error at the start figuring out which of 124 or 248 was on the black dot in box 7, but then worked out one of the Schrodinger cells in box 1 had to be odd, and the solve flowed like magic from there.

@wydadiyoun Год назад

just by reading the rules this sounds like a genius! How the hell could one think about such an idea and moreover implement it! I am looking forward solving this apparently genius puzzle with probably the most creative ruleset I have ever seen!

@pekuja Год назад

30:00 Couldn't you organize those four digits something like: AB, BC, CD, AD ? Then if the first one is A, the fourth is D, third is C and second is B, and if the first one is B, the second is C, the third is D and the fourth is A, and there's no "odd one out" in either case.

@joelstevens5670 Год назад

I feel for Simon with this sudoku. There is quite a simple approach provided you can focus on one aspect of Schrödinger cells, pairings (that if a digit A is present then there must be a digit B which prevents A from being determined). However, the idea of Schrödinger pairings is so crazy (since the digit pairings can mix with each other) that it is very easy to miss. If you label one AB as ‘A’ and the other as ‘B’, it becomes easy to see where ‘A’ and ‘B’ go, then ‘C’ and ‘D’ etc. Simon’s mistake was to use a third digit too early. Having said that, the video was very helpful because of the 1248 logic which reassured me at the tricky midpoint of the solve (also the fault of that pesky third digit). So well done Simon on sticking with it and my apologies that this comment is so late compared to the video release (a puzzle as brilliantly mad as this one deserves a comment).

@killamoosdraree730 Год назад

This puzzle was great! I wonder if Chameleon thought of the idea from running into some computer generated sudokus that seem to have multiple solutions. I have come across several that end up with “Schrödinger cells”. I have been known to complain vocally over those in the past. If you simply add a rule set requiring those cells to be “Schrödinger cells” then the puzzle becomes quite satisfying! I also love how the puzzle's rule set sort of harkens to a chameleon with it's ever-changing colors. Thanks so much!!

I really like these forced-2-Schrödinger cells. They immediately seem to produce fun new interactions with every other sort of Sudoku extension. I really hope we get more of this. We probably need a new type of symbol for these cells though, because the mixture of this and killer cages seems like it could be really interesting as well.

@johnpauladamovsky86 Год назад

*OUTRAGEOUS* Miscarriagement of taxitude...!!! - Lucius Sweet. The story behind this puzzle is ridiculous. A couple years ago, Simon Anthony came up with a clever way to describe what happens in a regular SUDOKU when you try to force 2 different digits into a single cell. He said, "there's no such thing as a Schrodinger Cell... NOW there's a whole genre of logic puzzles called Schrodinger Cell SUDOKU. This particular puzzle is the crowning exemplar of the new genre. Well done Chameleon...!

@disneian Год назад

Great solve! Such intricate rules and thought for the puzzle! Some thoughts on the solve: 31:49 I think if you coloured the AB, r6c3 would be quite obviously can't be AB; 37:05 Instead using DE in r6c3 when you are unsure whether DE could be C or not, I think using "XYZWT" (yea I arranged WT last like mathematicians would use xyzzy first then go back to w and t) or "MNOPQ" would signal that they are a different set of digits and you they could still be overlapping with C

@jonnybolton4659 Год назад

Such an interesting puzzle! I do agree that it's a little unclear regarding the resolutions at the end, it would kinda be good if the 59 pairs were resolved, which could easily have been done by placing a white dot on the 8 or 4 in Box 5

When you filled in the 3 and 6 in box 9 for a moment I was like , “no, you can’t do that!” Followed by yelling, “row 8”

@wayneblackburn9645 Год назад

The labelling that helped me was to treat each Shrodinger cell as having a 'first' value and a 'second' value. Then, using letters, an A in the centre and a B in a corner was an A that would switch to a B as opposed to a B that would switch to an A. In most cases A and B just go together but there could be an A to B, B to C and C to A sequence happening for a set of 3 cells so this helped me see the difference. Every letter in an S-cell with a A in the first position had to have a corresponding cell in the row/column/box that switched to A. It made it much easier to follow the logic especially with colouring according to the 'first' letter. I only needed the video to check my ongoing solution so any errors didn't just waste huge amounts of time.

@philipnitschko9093 Год назад

You know the Moment when you spot something in the Puzzle and Simon or Mark did not yet spot it? I would have loved to see Simon spotting the Schrödinger-X-Wing on X's (and Y's though ^^) But as always such a joy to see them solve such a brilliant Puzzle.

"Have we been doing sudoku? That is a philosophical question..." I don't think I've laughed harder! A new SimMarkism if I ever heard one! 😂😂🤣🤣

@andrewclark9809 Год назад

Loved this puzzle! For me, the key "aha" moment was realizing that r6c6 couldn't be an AB cell (using Simon's notation) because: 1) r6c6 forms a cycle with its black dot partner, due to the logic in column 5 and box 5 2) A and B aren't a valid black dot pair because of the logic in box 7 After a few more steps you can prove that r6c6 must be a 36 pair. Everything fell into place for me after that.

@cyndisision Год назад

Wow, this was a phenomenal puzzle!

@lylecampbell8288 Год назад

I used both letters and colours when I did this to distinguish between distinct states like AB and BA, and both were helpful. I used one colour for AB and a different one for BA. With the letters I used one corner mark and one centre mark so that I could distinguish AB and BA. Then the two states are the corner marked state and the centre marked state. This let me propagate the colours/letters much further through the grid.

@HunterJE Год назад

1:04:40 I think you do know - the other three cage cells in row 2 already have 2 6s and 2 3s, so to keep everything ambiguous the remaining spot must be 14 to avoid creating a pair or triple

@victoriam6569 Год назад

It's just another way of thinking! Bravo!

@samplename5159 Год назад

Slow and steady wins the race! Took me all of 10 seconds to go through the bottom row / box 9 logic compared to what felt like eternity by Simon, but then i stared and despaired thinking about box 1 until i gave up. I knew i could guess and bifurcate because of course all of those will be connected to black dots somehow, but diligently finding the logic that proves anything felt impossible. Thanks to Chameleon for the puzzle and Simon for video - if not our logic capacity we surely expanded our horizons today. 1:25:32 i think that's the longest i've been screaming at the screen about a scanning oversight

@MarushiaDark316 Год назад

I think an easier way of conceptualizing this puzzle - and probably how Chameleon came up with it - is that whenever you have two cages, they must be a pair. If you have three cages, it's a triple. If you have four cages, it's a quadruple, etc. Those quadruples could be pairs or they might not be, and you could imagine working backwards from a puzzle that had lots of deadly patterns in it to get to the starting point, you're just highlighting where they are in the beginning.

@carlossosa2907 Год назад

Yes, I think he got misdirected by the nature of the clues, the disposition of the cells indicated their parity.

@inediblenut Год назад

I think the wording is accurate. It says any selection in one cell must lead to a valid solution, but that does not mean that there are only two valid solutions. There are several valid solutions, I believe, but each cell contains at least one solution (perhaps not unique) for each of the two possible values in that cell.

@TheGreatAndMightyBob Год назад

Thanks for posting a comment about this. I'm not sure I agree (but I may be wrong).I think I am getting tripped up on the phrase "lead to a" in the rules. In my mind, its not that putting a specific digit in a cell doesn't allow for a valid solution to exist, it is that it doesn't it doesnt lead you to a complete solution at all. I might just be silly though.
