@Raven-Creations 3 года назад

It's easy to see why this earned its 100% rating. Great fun, it's like an Easter egg hunt. I particularly liked the way the knight's move was quite subtle. Too often, it's so restrictive that it makes a puzzle too easy, but this was perfectly judged. I especially liked the way all three rule sets often had to be used in unison.

@MrHippyCow 3 года назад

After listening to the podcast, when Simon asks if not spotting a digit is forgiveable I feel a twinge of sympathy for his shins

@Ryanape 3 года назад

The deduction he makes around 9:00 - 10:00 by sort of bifurcating a square being orange can also be made more logically/systematically. The 3 purple squares in the bottom-right box, all see R8C6, which therefore cannot be purple. The purple cells in row 8 all see R9C6, which therefore cannot be purple.

@Coyotek4 3 года назад

After failing to solve yesterday's 'Simon' puzzle, I was determined to finish this one. And I did ... after over an hour and a half! I started out well enough, but got stuck after about 40 minutes, stared for another 20, then started bifurcating the **** out of this, before seeing a key thing I missed and backtracking to my last 'proven' position. After another 20 minutes or so, I finally crossed the finish line. Total time: 1:32:15. Tough puzzle! (For me, anyway.)

@julianriml4860 3 года назад

Congratulations on solving the puzzle! It always takes me at least twice as long to solve the same puzzle as simon does but practice is key and simon is obviously a genius when it comes to sudoku ;)

@VeritasUnae 3 года назад

What a lovely series of deductions that falls out from the anti-knight and thermos! Really lovely to see.

@waynegurnham4764 3 года назад

They're all in disjoint subsets, this is amazing(to me) maybe it's common knowledge, but I think it's amazing how the knights move constraint has produced this disjoint subset from nowhere.. 🤯

@ericpraline1302 3 года назад

Definitely worth waiting for. Every time I thought I was stuck, something else suddenly materialised.

@glum_hippo 3 года назад

Marvelous solve of an extreeeemely elegant puzzle. More of this, please! I think this ought to be seen by more people. Abed makes some highly resourceful puzzles indeed!

@waynegurnham4764 3 года назад

I love that the knigjts move on 3's gives a disjoint subset on 3's.. non intentional I'm sure but as Simon would say it's beautiful.. im only half way through the video, I wonder if it will happen with any other number?!

@heliomance760 3 года назад

Oh, it's absolutely intentional - the whole thing is disjoint sets, you don't get that by accident

@livedandletdie 3 года назад

It's a nice Disjoint Set Puzzle. The best disjoint set puzzles are those which you don't need to state that they are disjoint set puzzles.

@Skeeto9 3 года назад

I posted an antiknight/thermo sudoku to the CtC discord server a couple of weeks ago using a similar setup to the one in the top right corner, so this probably helped me get a nice jump on the solve. I absolutely love the logic involved and how the rules interplay with each other around the crooked thermos. This was a fantastic puzzle, a lot of fun to solve!

@siorac1147 3 года назад

I have to admit that I needed the logic with the 4 in row 5 around 23:00 in the video - I was very much stuck until then. In the end I got to the end in 90 minutes total. Hardly a great solve, the puzzle deserved better - but I'm happy I managed to find the break-in.

@pema22 3 года назад

That's the perfect type of Sudoku for Simon to solve and me to watch. Pure fun - and no annoying set theory, geometry or phisto ring

@shashankjodge974 3 года назад

Really elegant puzzle and a pretty solve! Loved it!

@boman987 3 года назад

At 8:45 - the “right hand side” of the purple square in Box 8 cannot be in because: 1. The top-right cell is seen by all the purple in Box 9. 2. The bottom-right cell is seen by both the purple cells in Row 8. This eliminates the purple in Column 5 Box 5. I know it’s not technically bifurcation as Simon defines it, but I prefer elimination by “logic” than “testing”, even if I can do the testing in my mind. And I don’t like puzzles that rely on testing to solve.

@SpiritFryer 3 года назад

Ah, nice, I missed that in my solve and ended up eliminating by testing! Needed to remember that there's a purple in row 8 to eliminate r9c6

@CameronFerstat 3 года назад

Yeah I saw the same path here.

@geoff544 3 года назад

Yes, that was my path. But then Simon always does it in a more flamboyant way ;) If you ask him the time he will tell you how to make a watch! :)

@kinsell1166 3 года назад

@jonasdanielzik4112 3 года назад

At 10:00 you were wondering if you could highlight orange. Not the cleanest way to do it, but if you put orange in any colorless square, then double click it and hit orange again.

@nielcassidy8295 3 года назад

He could also select all the colored squares and hit orange twice...

@EirikLygre 3 года назад

The new "pen" highlighter has a beautiful way of adding circles or crosses on top of a color.

@mikes_.5_cent 2 года назад

Simon, as I watch you whip through the end of this, I wounder how I would ever spot something you did not.

@srwapo 3 года назад

104:20, definitely longer than I would have liked. I'm usually really good at thermo and knight's move. Dunno what was holding me up, I guess I was missing naked singles and limited digits into certain boxes because I wasn't really scanning the columns and rows, instead looking at the thermos and the boxes.

@six_5000 3 года назад

Finally, one I could get! Last week’s renban-fest was brutal

@livedandletdie 3 года назад

I enjoyed the Renbans, I struggled a bit with this one, mostly due to trying to solve it on my phone... The ability to not rapidly be able to Select a billion cells to edit at once, is painful.

@mathemitmanger3913 3 года назад

Well done, 4! Made me laugh.

@1a2s3d6a9s5d 3 года назад

34:39 you used the wrong 7 by knight move.. it's the other seven that I have been shooting about for 5 minutes :)

@michaelpeele5739 3 года назад

Only took me 5,911 minutes (with breaks). I did a LOT more coloring, using my inner Simon. I had a little trouble in the late beginning, watched Simon make 1/2 a deduction, and then I was rolling.

@Pwecko 3 года назад

It took me nearly two hours but I did it!! Very enjoyable.

@Raven-Creations 3 года назад

I'm sure being close to the monitor doesn't help. If you hold your fist out at arm's length, it should completely cover the whole grid. If the grid is any bigger, your scanning will really suffer. I raised this issue with Rangsk, because I noticed his eyes (and sometimes his whole head) were moving a lot when scanning. He said he needed the display to be large in order to get a high resolution video. I'm guessing you have a similar issue. I have a suggestion. I don't know what your hardware setup is, but assuming a worst case and you're using a laptop, and its built-in camera, you might consider this. Get a 10.1" 1080p monitor. Set it up to replicate your desktop, and prop it up in front of your laptop's display. It's small enough not to obscure the camera, and you get a more compact grid. If you or anyone else is interested, search Amazon for "10.1" 1080p monitor" for a selection. Caution: make sure you check the "native resolution" is at least 1920x1080. Some of the monitors claim to be 1080p but aren't, they just accept 1080p signals. Elecrow's is true 1080p. They also do a higher resolution, but it's not available in the UK yet.

@xWinGLP 3 года назад

i just noticed something special about knight's move puzzles and the puzzle from 2 days ago (Disjoint Killer by Quarterthru) where it sayed: "Cells that appear in the same relative position in their 3x3 box must not contain the same digit. eg the digit in r1c3 cannot appear in r7c6 as this would cause a repear in the North-East corner of the 3x3 boxes." that rule just happend to a lot of knight's moves puzzles. (not all i have to say)

@Michaelzehr 4 дня назад

I thought I was clever spotting the cells that saw all of the curved thermos in the northeast, and that the three tips saw each other and eventually became a 789 triple, and it was utterly useless for making progress. Aside from Simon's speed in scanning and solving, I'm astounded how rarely he goes down a dead end. I, on the other hand, often spend 20-30 minutes asking the wrong question, or coloring the wrong way, or noting something interesting that doesn't quite yield results.

(Comment not related to this puzzle but don't know where else to ask) - i got an update about the cracking the cryptic book that suggests some puzzles in the book have already been on the channel. Do i need to stop watching to avoid spoiling the book puzzles? How widespread is that?

@Anne_Mahoney 3 года назад

The basis of the book is 20 puzzles that were on the channel in the past. As I understand it, the new puzzles being made for the book aren't going to show up on the channel (at least not before publication, which is imminent anyway). So watch with no fear!

It can’t be 4 because the 4 in box 2 will either be R1C5, eliminating it using a knight’s move, or R2C4 or R2C5, eliminating it using sudoku.

@brampeeters9640 3 года назад

I don't know why everyone is raving about this one, as it was one of the longest and most irritating slogs I've had for a while. I _almost_ got the initial break-in, but just failed to spot the elimination of the middle cell. I needed the video to get past that point. But even then it just continually failed to fall into place. It took me close to three hours of hunt-and-peck worrying around the grid to finally get to the end. I like thermos and I like chess moves, but this one just didn't do it for me. Disappointing.

@julieannmyers8714 2 года назад

Funny how certain puzzles or puzzle types can be the antithesis of fun, entertaining or engaging. I nearly blow an artery trying to watch solves of sandwiches or skyscrapers... no matter how brilliantly set, they always seem tedious & vaguely malignant. I wouldn't even begin to try one... not that much of a masochist.
