- ** TODAY'S PUZZLE **
A debut on the channel today for Dutch mathematician rubenscube - a maker of puzzles for the game Super Mario Maker 2! This is a VERY nice sudoku called Quantherm Entangled... play the puzzle at the link below:
app.crackingth...
Rules:
Normal sudoku rules apply. Cells separated by a knight's move (in chess) cannot contain the same digit. Digits along a thermometer must increase from the bulb end. The green line is a palindrome ie it must read the same forwards and backwards.

Wow, I did not expect this. What an amazing surprise!! Thanks so much for the feature, I can't wait to finish watching the video. As for what you mentioned at the start, yes I am indeed the server owner of the Mario maker 2 puzzle community discord server. We have quite a bunch of Sudoku fans over there as well. It is very cool to see the overlap in communities. Anyways, thanks again for the feature, it is really special to me!!
Beautiful debut!! Can't wait to sew what else you come up with
Lovely break in
Excellent puzzle
Thanks y'all, happy to hear you like my puzzle!
You should make an "Escape the Mansion" sudoku. You make a path and when you land on a circled digit then it tells you something about a previous digit which helps you continue the path. I don't know how hard that is but it would be interesting.
That was a marvelous puzzle. I like a nice sparse grid. Puzzle was also very approachable. It looked like Simon was quite enjoying himself. Two of his favorite things clever logic and coloring. If you would have put a three in the corner, he would have smiled broad enough to make the Cheshire Cat envious. If this is an example of your setting skills, I will look forward to seeing more puzzles.
Love a puzzle with a quantum-tunneling 9-cell thermo
Loved the design of this! The interaction between the palindrome, knights move, and thermos at the start was so splendid, and some cool knights move intricacies at the end. Great setting and solving!
Glad you liked it!
It is not me solving the puzzle. It is you solving it. I can go do this on my own. But you have the gift of people skills and a kind mindfulness that is rare, but only now. The interweb is truly a thing of beauty. It pulls like a magnet once you start it. Community whenever you look. I like the words you use and the poems you remember. That is unique for a specific reason.
Love at around 29:00 Simon “this 27 pair is not resolved” comes back about a minute later “oh this 2 is resolving this 27 pair”
Knights move always makes scanning a menace lol
A sparse grid with a logical break-in. This is a wonderful puzzle and not devilishly hard.
That break in was super smooth! Love it!

The Let's Get Cracking was a few seconds later at 3:44.
@@100beep5 The timestamps are intentionally early
interesting as simon noted that (the grid) was "Incredibly spartan". - Indeed so - no digits !
Sting in the Tail: 1x (22:41) is actually Stingeth in the tail (very Shakesperian !)
25:18 today - really like the starting idea
Very satisfying how those thermos resolved themselves!
36 minutes to finish this. I let out an audible "Ohhhhh!" when the thermos resolved themselves. Cool trick.
Very nice logic. I think knights move is one of my favorite constraints
"By Tigger jumps" at 18:50 is a new Simon phrase to add to my list of favorites
40:07 for me - I feel good with that time. I was getting worried that it was taking so long to disambiguate the 68 in the middle of the palindrome, and it was the last thing I solved.
As a fellow SMM2 Puzzle designer, I found this puzzle enjoyable, and beatable. Which is rare for me!
Great puzzle and loved the palindrome and thermo linkage. I got stuck about 3/4s of the way through so came back to see what Simon was doing and really happy to see he had taken to colouring exactly the same way I had done it, which was reassuring
I love how the Super Mario Maker Bubble and the Sudoku Bubble overlap somehow
It's been said before, but I think it bears repeating. Colours are useful placeholders for UNKNOWN digits. Once the digit the colour represents becomes known, the colour has served it's purpose and can be removed from the grid.
This removes clutter from the grid; makes the remaining sudoku scanning more like regular sudoku scanning that you're used to; and reduces the amount of further mark-up required - you're not having to wastefully enter both a digit AND a colour on each cell, with the additional mode switching this entails.
It would have saved you time; perhaps enough so you wouldn't have been late for your Zoom meeting. 😂
I hate the feeling when the colored cells are removed. It feels Like a black hole. 😱
Superb break-in
I didn't think it was too tough after that
A sub-hour solve, which for me is great! Very nice break-in to this one, I enjoyed it all the way through.
Glad to hear you like it!
21:02 ... I didn't act on this, but ...
.
.
.
... you can tell immediately that the thermos have to connect up (else there can't be a unique solution); sure enough, I figured as much out in my solve.
Nice puzzle!
This sudoku reminds me a lot of another sudoku which I think was called ‘Moles’. The idea of digits tunnelling to continue on from each other in order to force their values is extremely satisfying. Great debut puzzle, thanks Rubenscube and Simon for the video (glad you made it to the end in time, it was a lovely solve). Knights moves can be notoriously difficult to spot but they do make for some fun solve paths.
22:22 for me, really fun puzzle!
That was great, Simon. Thanks, Rubenscube, for the puzzle. It is definitely going on my list to try in a few days after the details of Simon's solve is not so fresh. As always, a very enjoyable video.
The break-in was truly elegant. It was right up my alley. :)
That took me a long time. But proud to say I got to the end on my own, and just a tiny logical leap half way through. I do tend to struggle with my chess moves
This was a very exciting and beautiful puzzle with the ideal level of difficulty for me .... with enough challenge but without driving the brain insane. It usually takes me two or three times as long as Simon and Mark, but that doesn't bother me. The joy of solving the puzzle is important.
Really nice puzzle, not "that" hard, but a great satisfaction to untangle the logic. And also: not "that" easy either to not feel smart sometimes. :) These are the best. Thanks for the puzzle and for the video (I followed a slightly different pattern, but the main points are probably the same)
Nice puzzle, super difficult for little ole me. 117:48, especially had difficultly resolving the last bit. Now to watch Simon's solve
Simon, I know you ask occasionally on what types of videos you should do, long or short? I just thought of something. Since the weather has been nicer, I have had less of an attention span on sudoku. During the winter I cry when it's not an hour long. lol. So maybe during summertime make them short and sweet and wintertime when everyone is stuck inside do longer puzzles. Anyway, just a thought. LOVE YOU SIMON!
I tried solving this one on my own without looking at the video, and I did it! I finished with a time of 78 minutes, but I did it! Watching this channel has really helped me improve at sudoku. I'd never have known how to tackle grids with no given digits before, and I'm really getting into the variants.
Totally agree! And don’t despair re time…I was determined to finish too…it nearly took me 2 hours 😆
You should be proud of your time. The higher it is, the more it means you've learned something. Anyways, good job on the solve y'all!
Well done Simon. You duplicated my colouring perfectly! 😁
36:03 for me, that was fun!
"If I was Mark I would pencil mark this thermometer. I refuse to pencil mark this thermometer." 😂😂😂
22:14 for me. i like how this got resolved.
What helped me was at about the 10:30 mark in Simon's solve was realising that every digit has to appear on a thermo somewhere. (although it took me more than 10 minutes to get that far)
Well this took me 64:06 and I almost gave up near the start (luckily when I reopened the tab it still had my progress). I started with the colouring then realised I wasn't sure the digits on the palindrome (well half of it) were all different, gave up, closed the tab, then immediately spotted that the knight's move etc means they ARE all different, went back and slogged through the rest of the logic. Really nice, I like knight's move puzzles a lot and I was quite proud of being able to see that it was all going to force the thermos somehow, so just working towards that and focusing on when I got a colour to land on a thermo. Bit of mutually exclusive knight's move shenanigans in the tidy-up phase and a lot of scanning the grid for weak cells. Nice way to spend an hour.
Man, that was a fun one! Thank you guys!
Next app should be Jiggery-Pokery Sudoku!
Simon getting excited and repeatedly saying "seven" reminded me of the scene with Monica from Friends 🤣
Why is 6 afraid of 7? Because 9:36
Yeah, that always gets me, too.
If everybody can just bluntly understand set theory, there is no stopping greatness. I love opening a puzzle with 2-4 variants with a decent difficulty level. 5/5 is for a couple of people only. Some people on LMG finishes all the puzzles. I go with flavor.
17:01 for me. Very nice idea and perfectly executed, awesome puzzle!
Simon coins YET another new word: Purplefication.
30:22, looked intimidating, but ended up being pretty fun. Almost lost it at the end with a mistype, but I managed to figure it out before giving up.
16:06 for me. I think this is the quickest I've ever done a solve compared to video length.
Found the break in pretty fast but it took a while to realize the 1 at R3C6. The red centers on the palindrome were the last to be filled in. Fun puzzle. By Jiggery Pokery (27:05), where's that on the Simarkisms?!?
29:47 - I think judicial pencil marking sped up my process, I caught the entangled thermos fairly quickly, and the rest was just a bit of a grind through the knight's move. Proud of my time, though!
That was pretty approachable for such a sparse puzzle. It's one of the reasons I enjoy the chess puzzles - as long as they're not too tricky.
19:49 for mea! Colors to solve the thermos. Then just a normal anit knight.
Heard on CtC: That's yellow cos it's a 5
Heard in a preschool class somewhere: That's yellow cos it's a 5
85:41
I very clearly need to brush up on my Knight sudoku. I got the thermos completely set and the palindrome almost complete set within 10 minutes. The rest took me over an hour.
Got this one done in 230 minutes (I think that's what the timer means, anyway). Honestly incredible how little the thermo and palindrome actually help after you solve them. Was stuck on a lot of 6-8 pairs all over the place that never seemed close enough to solve using knight's move or sudoku. I suppose that's the "quantum" part of the puzzle? A lot of this puzzle seemed to solve after finding the 1s and 2s, it seemed, but 6s and 8s were nigh on impossible until the final few minutes of the puzzle for me.
yeah there are some amazing puzzles in the new app updates!
Palindromes, knights move that forces coloring.. 4/5. Those are the most satisfying. 35 minutes says it is not. 1 hour 30 minutes is worth a movie.
There where a couple of puzzles in the past. One stood out in particular. Where the first 2 top digits in the cages showed 32 or 41 for example (read from left to right) pointing out the cage total. With a knights move. You had to find the 158 in box 9 at the end (was it 158?) to place a couple of 2s in the puzzle before the coloring could continue so as to solve the puzzle. Two years back maybe? I will never forget that one. 17 out of 10.
Renban and German wishpers are reaching sandwich levels now.
I somehow mis-scanned and filled in the 13 pair in box 1 when it was not yet clear how to fill it in, and filled it wrongly. That gave me ~ 20 minutes later an unfillable cell (a 28 pair in box 9 which could be neither 2 nor 8). I had to watch Simon's solve until I got something different so I then knew how much to rewind my solve. Took in total 167:30.
Got it in 42:34. I had some great progress by about five minutes in, where I had all of the thermos filled by that point. The rest took me a bit longer!
I got through the break-in, and was busy filling out the rest of the grid, but I must have gotten my wires crossed somewhere, because near the end I hit duplicated digits.
I tried rewinding a ways to sort it out, but it happened again. So after close to an hour's work, I threw in the towel. I don't have the energy to re-start right now, so I'll just have to be content with the knowlege that I could have solved it if I wanted to.
I very much enjoy sudoku puzzles with chess piece movement restrictions (in the app they include knight, king, and a variant where 9 is a queen) I hope some of the more devious setters are working on a sudoku version of castling or en passant as we speak
19:52 solve the broken thermo/palindrome was the only place to look really. Easy break in
Serious issue for me: I've occasionally "solved" a knight's-move puzzle only to discover to my dismay that I've violated the constraint. Is it possible to set up the software to check for knight's-move collisions?
3:48 -- I'm stumped at this point. It seems as if I have to force a certain palindrome number (my blue) onto the middle thermo, and another palindrome number (my purple) onto the bulb of the left thermo. But I can't see how.
5:40 -- Thank's for the heads-up with the orange (the middle cell) and the tactic. I've done all the thermos, and all but the two middle cells of the palindrome.
7:30 -- Now look at the middle cell of the left block, at the kink of the palindrome. Does it go at the end or beginning of a thermo?
21:00 -- Thank you for eliminating the 9 from that cell for me.
The END -- I finished it after a long time, before watching the last part. Nice to see the same solution, that I didn't miss any knight's moves. Those "two middle cells of the palindrome" were the 68 pair that took forever to disambiguate.
It’s certainly possible, but the problem is that once that happens, people are inevitably going to start asking for more and more rule checkers, and it’s going to be way too burdensome to both build all of them and also build a way of indicating which checkers the puzzle should use.
@@Deathranger999 f puzzles has a lot of different rule checkings and that's actually why I prefer to use that software over ctc's one
@@killermelga Cool.
Simon, what if you where Dexter, hiding in plain sight? Or the Mad Hatter that drinks tea to escape "trampoline wars". I always wonder what happens when the recording stops.
36:02 for me. I got horribly stuck at the end. I failed to spot some knights move.
yes yes yes yes yes, oh that is so cool
Lol I can't believe the one time Simon had to run take a call at the end he managed to not miss any miscoloring or grey flash in any cell!
38:38 for me, got the break in immediately but so slow with the knights move deductions..
Are you guys going to cover that one puzzle a while back about entropy and balancing stuff?... It had a lot of scales on it. I tried doing it myself but I got stuck somewhere and I stopped after around 3 hours of dead ends
He did that as a Patreon video. They tend to not do puzzles with complicated rulesets on the main channel.
@@doublelxp dang
51m38s for me, yikes. I really loved the interplay of all the palindrome digits, and I did great at colouring the various cells and tracing the implications through the puzzle, but what I completely failed at was connecting the given digits with the colours and narrowing down what could be what. (e.g. Simon's logic that determined what number yellow is). Soooo instead I pencil-marked the entire grid, which got very messy and slow. Oh well, maybe I'll be quicker to figure out what logic to use next time!
(This is bringing back my abysmal university math performance... I was always getting stuck about what approach to use on any given problem!)
looking at the empty grid, I'd have called this Penalty Shootout.
The very cool initial logic (from 4:39 to 9:22) is an application of *Apiyo-Thoen's* theorem:
_In any _*_anti-knight_*_ sudoku, if the center cells of any two diagonally-adjacent 3x3 boxes have the same digit, you can force that digit into 2 more cells, then 4 dominos, then 1 more cell._
See CTC video *A new sudoku theorem* (th-cam.com/video/yT3Fqt8MQUc/w-d-xo.html), featuring an astonishing puzzle by *Aad van de Wetering,* in which the above mentioned theorem was showcased. Aad called that puzzle *Theorema van Thoen* which presumably means *Thoen's theorem.*
However, that was not a new theorem, as it was first implemented by *apiyo* in a mind-blowing puzzle featured on CTC about 17 months earlier, on Oct 19, 2020: th-cam.com/video/Donhjrl-V1g/w-d-xo.html
So, it would not be fair to call it *Thoen's theorem.* It should be called either *Apiyo's* theorem or *Apiyo-Thoen's* theorem.
And these are the hands we're given - Genesis
A bit of a pity that SImon did pencilmark (two of) the thermos before discovering that not only two of them, but all three are connected.
I was on page 7 and tried to catch up selectively. Just because I can not leave a good 3/5 or 4/5 puzzle behind. I ended up on page 10 after 3 weeks. So yesterday I just started on page 1 again.
94 minutes from me. In keeping with the formula T x 3 or T x 4, where T is Mark or Simon's time.
The nightmare puzzle by Philostopher (?) can you link to that?
I have a question about palindromes. Can numbers repeat along the line?
In general they can, yes
@@rubens_cube Thank you, thought that would be important to know or at least I would have been so curios that I couldnt focos on the puzzle. thanks :D
How could you have a palindrome line that doesn't have repeats? That's the definition of a palindrome: first digit equals last digit, etc.
It really is okay if you don't colour after the puzzle is solved.
Hello, I tried the puzzle myself ang got the "looks good to me" finishing sign even the knight's rule has not been met (first I was thinking that the puzzle don't have a unique solution, but I overlooked some of the knight's rules and got the correct finishing sign, later on I discovered my mistakes with the help of your video) Is it something I need to count with when trying other puzzles, that it checks only normal sudoku rules, or it is some error?
Yes, the check function doesn't check against an actual solution. It only checks basic sudoku rules, so no repeated digits in rows, columns or boxes (and even then, it doesn't always seem to check those correctly, depending on the puzzle).
If you use the menu option in the top left, and select 'home', it takes you to a CtC home page with some controls documented for the software. It does tell you on this page that the check button only checks basic sudoku rules and "may not work on non sudoku grids or special constraints". There's not much "may" about it. It doesn't. But few people who use the software have probably read this line, so it's a shame the button doesn't do what people naturally expect it to do. Not helped by the fact Simon always reacts to the confirmation it gives as a confirmation his solution is correct.
24:47 for me! A quick break in but got slower haha
At 14:04 I cannot understand why yellow cannot be 4 and must be only 5? Can someone enlighten me?
NVM: I found the nights move constraint on the right side of the palindrome
Very cool. Something like 50 minutes; I lost my timer.
I really don't understand why you would flash all those colors. If you simply define it as possible locations in the box, it simplifies the colors. If there is 1 in the box: that's it. If there are multiple, it is one of those. No need for a flash.
I find a grey flash on a colour is very helpful.
Simon used to put solid colours in for all possible locations of a colour in a box, but it's too easy to mistakenly scan a single solid colour cell thinking it's the only place for the colour in a box when it isn't.
Mark was the first to start using grey flashes for this purpose. Several commenters on Simon's videos used to encourage Simon to adopt the same practice. I think it helps to distinguish the different meanings: solid colour = this cell IS this colour,
flashed colour = this is one place this colour could go (equivalent to a corner pencil mark).
Don't see Slitherlink Take Me Home in patreons. Not there yet?
It goes live tomorrow. I had to learn the song X)
@@CrackingTheCryptic Looking forward to it!! 😃
Never thought the day would come but I’ve solved something faster than Simon did 🤓 28:31 for me
At 25:15 why can the 1 not go in box 3?
Regular sudoku + knights move means the 1 in the domino at the end of row 4 (box 6) rules a 1 out of the domino at the end of row 3 (box 3), whichever way round the 1 goes. One cell will be in the same column, the other will be a knights move away.
Am I the only one that heard George Ryan doing his "Wow-wow-wow-wow" at 9:05? (probably so =[)
I'm not sure to get why the 9 can't go in r2c8 or r2c9 at time code 20:28 of the video, I mean I don't get why it break the 7-9 pair, to me you can still put 9 in one cell and 7 in the other one. Anyone to help me understand this?
If you put 9 in r2c8 it will see r4c8 by Sudoku and r4c9 by the knight's move. If you put 9 in r2c9 it will see r4c8 by the knight's move and r4c9 by Sudoku. Therefore 9 can't be in r2c8 or r2c9. Dominos that align like this are a commonly useful pattern in anti-knight Sudoku.
@@rubens_cube Oh thanks! I didn't see that knight moves here! Now that I see it it is obvious thank you!
It's a Portal thermometer!
Monica from Friends be like 9:38
just saw the thumbnail on one of my other favourite science yt channels "urknall weltall leben". who is the thieve? 😄
Entanglements can be “quantum” now? Someone tell Jada Pickett Smith
The good puzzles. Simon always does the 35-120min and Mark does the 17-40min. What I am trying to say is.. If you solve the puzzle too easily, I lose interest. I am not the only subscriber. At least it is not me trying to keep half a million people satisfied.
done
No we do not want you to color the grid. We want you to stop using a color the minute you know what number it is.
