Stunning solve, Simon, as always. Thank you very much for featuring this one (and your hunch about the title was correct)! Your kindness is always very appreciated! :) On a different note, dear viewers, if you have not seen Philip Newman's incredible puzzle from yesterday, PLEASE watch it (and try it)! It's a once-in-a-lifetime kind of experience.
I thought at first the title was hinting at the Branson space scratching mission, since gravity is heavily involved when the plane starts "falling" back to earth. And the thermos look a little like these jets carrying the rocket plane to ignition height. But Simon says the Sudoku is from some time ago. Thank you very much!
I missed this and solved it a week late. I absolutely loved it. Not too difficult and everything went in it' place with very little force, once you spend a thought on the thermos in boxes 3 and 7. On this channel we praise the exceptional puzzles, the really hard ones but we should also give credit to these satisfying mid-range puzzles. This was well thought through and a joy to solve.
Just have to say not only have you reignited my love of sudoku, but this channel is the one I currently fall asleep to. As an insomniac finding things I can wind down to is amazing! Thank you
Simon, Don't be afraid to take a vacation from us. We would understand. We love you and would wait for you to come back. I don't want you to get burned out.
There is also the option to record multiple puzzles and solves in advance if he finds the time and passion for it and then have a vacation while still having daily uploads.
I don't know, it's not healthy to do a ton of extra work before you go on holiday and then have to catch up when you get back, I know that's something we're forced to do a lot in our jobs but it's not a thing you should do if you don't have to. Much better solution would be if they want to keep doing content during a break, have guest solves from some of the brilliant puzzlers that orbit around the community.
@@Krillol Sometimes I wonder if that's why he doesn't know what day it is in some videos - ie, records a few at once. I'd also hope he has a mechanism in place to give him some time away when he needs it.
I'm glad someone said it. He seems really mentally fatigued to me. I think he needs a break. I know the puzzles on the channel have gotten harder, but I sometimes see him struggling with logic I never did before.
"Where do I look now? Where the cursor is... ah yes!" - Simon is really taking the comments he's getting to heart :) Wonderful puzzle, wonderful solve, I'm in awe as always.
Simon is only one mind, and needs to follow many leads at once, which makes him (often) forget earlier deductions, even when he marks them down with colouring.
I came at 8:30 to smash dat like button, I'm back at 11:30 to watch the video. Had a little football match to watch in between. Normal service resumed and I'm so glad this video (and then Mark's) is here waiting for me. Thanks guys.
One of the fascinating thing I find about Simon is his anti-locality of attention. Like placing the 4 in box 7, his immediate attention is away from the action. Or placing the 7 in Box 5 - doesn't follow up by removing the options in the thermo square below. It is the opposite of my own. I wonder if that's why he's better at doing these than me?
There were several points where, if he had just stayed in the same spot a minute longer, he could have cleared a lot more logic. This was especially true in box 7 where the vertical domino in the top left had to match the vertical domino in the bottom left of box 8, which in turn put all the pressure on the gray thermo. All it would have taken was a little more of the type of logic he put into box 3. It took him a while to work out those values the long way around.
The colours over the grey lines reminded me of a map of the London underground. Would be great to do a thermo sudoku with that in mind (or something else with lines?)
I feel like there's imo a simpler way to see what Simon's getting at around 13:00 without using the created 8-digit region. Because we know the orange cells in box 3 are high, and a 1 can never go midway along the thermo, the "12" in blue can only be 1. At that point, you can do the same with 2 and 3, which have to be minimized along the purple thermo...
24:32 There is already a way of resolving the 57 cell in r1c4, but it's not that easy to spot. Firstly, the 4 in r3c4 can't be on the thermo in box 1, so it is in row 1 in box 1, which means it's not in r1c9. Therefore, the 4 in box 3 is in r2c7. Next, we ask where the 5 goes in row 2, as it cannot go on the thermo in box 1 and now can also not go in row 2 in box 3, so it is in row 2 in box 2, meaning that r1c4 is not a 5 and is thus a 7. A bit long winded, I know, but it resolves this part of the puzzle quite a lot sooner.
I did not manage to solve the magnificent puzzle without throwing a glance at the video. After analyzing Simon's amazing solving strategy, I came to the conclusion that he could have done even faster (Simon, in all modesty, because afterwards it's always easy to tell :-) ). The digit in r1c5 can't be a 3 (because the only possibilities for r1c9 would be 1 or 2 whereas the minimum at the top of the thermo is a 4. Same applies to the 4 in r1c6, forcing a 1,2 or 3 into cell r1c9 which breaks the puzzle. This leaves a 1 or 2 followed by a 2 or 3 for the first two cells of the thermo starting in box 2. Then, assuming a 1 in the bulb forces a one in middle cell of box 3, forcing a 2 (at least) in the bulb of the thermo starting in box 6, thus breaking the puzzle after few iterations. As a result the the first two digits on the long thermo are a 2 and 3. Again, no misunderstanding: This is just after analyzing and far from what I struggle with in the beginning, even with peaking at the video once in a while.
RE: 29:45 the bulb r6c1 can never be on the purple thermo because at least one digit after it on it's own thermo is earlier on the purple thermo than any cell it could go into. It therefore must be r8c2 as it's the only cell it doesn't see not on either thermo.
24:20 for me. I needed a couple of ‘what if’ questions during my solve to keep going and now watching the video I’ve realized there was an easier way to get there by pure logic. Maybe I’m pushing too hard the timer and therefore missing some nice enjoyable logic?
I have never been remotely interested in watching a bunch of men (or women!) kicking a ball ⚽ around a field, and that certainly doesn't change just because half of them are from my country and half of them are from another country 🤷🏻♂️
at around 29:48 The grey bulb has to go either in the center of box 7 or on the purple thermo BUT the purple thermo's bulb or second digit absolutely will fall on the grey thermo after it's bulb so the grey bulb MUST go in the center digit of box 7. You just about went there then wander to try and figure out what number the purple bulb was.
@16:45 r1c4 becomes 457 -- I don't see how the 6 was eliminated. Later the "key" to the solve was to eliminate 2 of the numbers in that box. The 7 Simon saw was, in my version a 67 at that point in time. Did Simon accidentally bifurcate?
Or did he just mistype, read off his typing, and get lucky? Or was there piece of logic that Simon didn't explain? Mind you, I'm very grateful for his explanations . . . Sorry about the Euros, by the way . . .
@@Frykizh Once you've worked out that 6 is in box 2 row 2, you know that you've got a 789 triple in row 2, leaving a 1456 quadruple left behind. However, the 4 cannot go in row 2 box 2 because of the 4 in r3c1, so the only place for a 4 is in box 3. Once you've got that, you can also place the 5 in box 3 in r1 c9, which sorts out the green 7. It's admittedly a decently long chain, but it's all done with incredibly simple deductions.
Hey Simon, at 32 mins when you figured out the 7, your earlier logic figured it out sooner. Once you had the 4 in the bulb below it, that 4 could only go in r1 in box1, so it had to be r2 box3, so the green bulb had to be r2c8, thus the 7. I love when I see things before you. It's rare and wonderful, and I learned it all from you.
Once you get the 4 in the bulb of the thermo in box 2 you can place a 4 in box 4 since it can only go in one place, and since you already determined that the small thermo had to start with one of the digits from those 2 specific cells in box 3 you know it's a 7 right away. Another way to see that is that after getting the 4 there are only two places to put a 5 in box 3 and both places see a green.
The train of thought has been diverted to platform 4. Please do not open the doors until the train has come to a complete halt. Thank you for travelling Sudoku.
Love both the puzzle and Simon's solve. Just for once I had a great start, but then it all slowed down to a trickle as I spent way too much time trying to color all of the top three boxes before looking at the rest... :) The first questions to ask for a great start into box 3: Where does the 1 go? And where does the last two digits on the long thermo go? So, where does the 2 go? Now, what about 1 again? And the 3...? And then I made the mistake saying something like "Now we're cooking...!"
Noooo! The puzzle extravaganza is amazing and approachable! Great logic, great solve paths, and not a headache at all! That jovial can do puzzle like that AND like this is a testament to her intellect.
One small thing -- once you cleared 6 from R1 and R3 in box 2, you can remove it from R2C2 and R2C3 (and/or pencil it in R2 in box 2) which makes some logic there a bit easier.
I remember in high school before I learned about atmospheric pressure that I *did* think that the reason one couldn't raise liquids above a certain height in certain ways was because of gravity ...
A quicker way to get the digits in box 3 would be to remember that 1 can't go on the thermos so needs to be in the orange cells along with the two digits from the end of the thermo, thus forcing the blue domino to be 2-3.
(Yes, I did take a one day break) At 32:48 Simon deduces the thermo staring in r1c4. But leading up to the situation at 24:40 we know that r2c2 is an 89 par (because at least one of them is on the thermo). We also know there is a 6 in row 2 in box 2, so no 6 in r2c3. Which had given at that time a 789 triple in row 2, outside box 2 so a 789 on the thermo. This did of course not yield anything during the solve Simon did between 24:40 and 32:48....
Based on the point where Simon accidentally put 2 in 3 cells of the same box, I had an improvement idea for the software. When you are in the top mode for putting the value in a cell and you have multiple cells that are in the same row, box, or column it puts corner marks instead
Quickest way to solve box 3 is to ask what happens if the end of the pink thermo is a 9? It collapses the grey thermo, and the next available digit is a 3, forcing 321 into the rest of the pink thermo. That holds true whatever value you put on the end.
Everyone, you CAN do the miracle killer sudoku!!!! It's amazing, and it's not nearly as difficult as a lot of the other ones on this page, quite approachable.
I would like to See your reaction of Mark solving puzzle and Mark reaction of you solving puzzle, it might be two different puzzles. Thats not matter. Thanks.
I just listened to your interview on Formscore, which was awesome, and you mentioned that no one ever talked to Mitchell Lee about The Miracle, and I'm wondering if you would ask him about doing a setting video for it? I know the puzzle is a year and change old and miracle-style stuff has somewhat run its course, but to me there's no reason why you can't revisit a legendary old puzzle from time to time in the setting videos. Mitchell did that solving video for CtC once and it was great so I'd love to see him again. I would LOVE to know how he discovered the implications of that ruleset and how you could use it to lead the solver on a journey like that.
I have a question. At 16:40 Simon deduced r1c4 couldn't be 8 or 9, or 1 through 3, but only penciled in 4, 5 and 7 - not 6, which was also a possibility. Then at 32:45 deduced it couldn't be a 5, so you penned in the 7 believing it was the only option remaining. Can anyone help me deduce how to rule out 6 there?
If it were 6, then the 13green triple in box 1 means there can't be a 6 in box 3 on row 3. Similarly r1c4 also rules out 6 on the end of the purple thermo in box 3 r1c9. Then there is no way to place the 6 in box 3 at all.
Even though sudokus like this one appear to be far above my abilities (I try and come up with a few ideas that are terrible and ineffective compared to Simon's techniques), I at least am smart enough to appreciate how ingeniously Simon solves them. Obviously the setters deserve an enormous amount of credit too but it's only by seeing Simon's solution you can understand the brilliance of the what the puzzler setter created.
8:02 "What about this thermometer?" [purple in box 3+6] [continues to explain that it can't start too high because it otherwise runs out of digits] - This is much simpler: This thermometer has at least one blue digit on position 2 or 3, and the blue ones are at most 4 (as shown just before). So its bulb can be at most 3. (I guess that's what Simon also concludes, and even more, but without using the nice blue coloring he added before.) 15:05 "1 goes in those squares by Sudoku, and that means 1 goes in these squares by Sudoku. Seems slightly strange to say when solving a Sudoku, the logic you are doing is using the rules of Sudoku." - I guess one could say "because this row has/these rows have already a 1, and this box still needs a 1", but that's a bit long.
Could have limited R1C9 much earlier too. 5-8 all had to be on it somewhere, and every single spot on the thermo saw the corner either by region, column, or row. So from the start it had to be something that only appeared once on the thermo, ie 4 and 9.
I think it would help if the online software removed pencil marks automatically like all the apps do. So many times myself, Simon or Mark, and I'm sure others, forget to remove a pencil mark when placing a digit which makes the solve take longer cuz you miss it. At least in a classic sudoku sense, ie placing a 5 would remove any pencil marked 5s that see that 5 that was just placed.
Help, please, I missed Simon's leap of logic at the 16:50 mark...How did he come up with 457 in Cell 1 of Box 2??? How did 6 get excluded as a possible digit???
It was a matter of where that digit needed to appear in row 2. It wasn't the 2 or 3 and couldn't be on it's own thermo or it's own box so it needed to be the same digit as in either r2c7 or r2c8 neither of which had a 6.
I get the sentiment behind not immediately Goodliffeing every thermo, but not pencil-marking a 7-digit thermo feels a little on the precious side to me, anything else that let you limit a bunch of squares to three center pencil marks each you'd do in a heartbeat...
Someday someone will figure out Simon's Achilles's heel and put a 9-length thermometer in a puzzle, he'll be unable to solve it because just putting in all the digits would technically be Goodliffing...
We will eventually bring Simon over to the dark side (pencil marking thermos). Every time he pencil marked a thermo he made progress. Every time he resisted, he got stuck.
And because he didn't think in terms of the thermos and their pencil marks there were several times he missed things that could have been resolved by just cleaning up the marks that he did make.
Found a good way to start at box 3. The thermos in box 3 and protruding into box 6 have to be 8 unique digits. That immediately placed 1s and 2s in box 3. Similar logic in box 7 later on. Nvm. Simon found the same logic later on XD
I am so tempted to try to create a puzzle sudoku with less than 17 given cell elements, just to shake up the logic that you need at least 17 givens for a classic sudoku. This seems like it can't possibly work though. That and my general lack of setting skills keep me from being too serious in this temptation.
You might have a great market selling pillows (or T-shirts or mugs) that have specific sudoku puzzles featured on the channel. Not knitted, obviously, but perhaps you partner with some setters and feature a handful of puzzles.
Simon really needs to remove colored things in grid after they are used up , because he comes up with a lot of great logic he shows with color. Then he doesn't look at it again because there is color everywhere in grid and most is no longer useful.
Simon's reluctance to pencil mark thermos is just... strange. I don't know at this point if he just refuses to as a joke, or if he believes it's a better viewing experience without, but I can say I really prefer them with pencil marks.
I'm surprised he didn't include the bulb in that upper right region, as it's a nine square region that all see each other and it would have given him the 1 immediately.
Wow some1 has subbed and notifications on AND spent time to click on this just 2 be a hater lol. Nice time spending dude! (Could be a bit too but like.. y lol it’s just a normal Simon trying to solve a puzzle 😂)
They probably spent less time doing it than you did mentioning/replying to them. They're not worth the effort. Just call them "margin of error" of the voting system.
You always say the numbers on a thermo rise ‘like mercury’ in a thermometer, but surely the analogy is more related to the numbers printed on a real thermometer that mark off the different temperatures increase from the bulb end.
The early logic was confusing. If instead you ask where 1 can go in box 3, you get a 'triple' of two oranges and 1 and the results up to ~15 minutes follows.
Stunning solve, Simon, as always. Thank you very much for featuring this one (and your hunch about the title was correct)!

Love both the puzzle and Simon's solve. Just for once I had a great start, but then it all slowed down to a trickle as I spent way too much time trying to color all of the top three boxes before looking at the rest... :)
The first questions to ask for a great start into box 3:
Where does the 1 go? And where does the last two digits on the long thermo go? So, where does the 2 go? Now, what about 1 again? And the 3...?
And then I made the mistake saying something like "Now we're cooking...!"
at 42:41 you know the order the 28 pair in box 5 has to go in because where does your 2 in column 4 go?
Took me 43:12, finally beat CTC time on a medium-hard puzzle!
I loved that middle box logic to get that 3 at 25:00
But how is there not a 8 in the lowest of those 4? He stated it could only be a 4567, but why not 8?
@@dontdreamon9026 if it was an 8 the cell below it would be a 9. And those two cells see r3c5 which is an 89 pair. So that cell would break.
82:04, feel like I had to try all the numbers to really prove to myself that certain digits wouldn't work on the thermos.
It's like a water clock the way Simon solved it.
Note to self: never ever attempt another jovial puzzle ever again. Ever. over three hours to get only eleven digits and a massive headache
Noooo! The puzzle extravaganza is amazing and approachable! Great logic, great solve paths, and not a headache at all! That jovial can do puzzle like that AND like this is a testament to her intellect.
I love the uncluttered way Simon used to start the solve. Then it got REALLY hard.
One small thing -- once you cleared 6 from R1 and R3 in box 2, you can remove it from R2C2 and R2C3 (and/or pencil it in R2 in box 2) which makes some logic there a bit easier.
I remember in high school before I learned about atmospheric pressure that I *did* think that the reason one couldn't raise liquids above a certain height in certain ways was because of gravity ...
A quicker way to get the digits in box 3 would be to remember that 1 can't go on the thermos so needs to be in the orange cells along with the two digits from the end of the thermo, thus forcing the blue domino to be 2-3.
At 12:50 one might ask oneself: "where does 1 go in box 3". And keep the orange hightlighting.
(Yes, I did take a one day break)
At 32:48 Simon deduces the thermo staring in r1c4. But leading up to the situation at 24:40 we know that r2c2 is an 89 par (because at least one of them is on the thermo).
We also know there is a 6 in row 2 in box 2, so no 6 in r2c3. Which had given at that time a 789 triple in row 2, outside box 2 so a 789 on the thermo.
This did of course not yield anything during the solve Simon did between 24:40 and 32:48....
Based on the point where Simon accidentally put 2 in 3 cells of the same box, I had an improvement idea for the software. When you are in the top mode for putting the value in a cell and you have multiple cells that are in the same row, box, or column it puts corner marks instead
You went full Goodliffe. You never go full Goodliffe.
0:37 - "it's a... it's a... it's a..." (Fifth Element)
Quickest way to solve box 3 is to ask what happens if the end of the pink thermo is a 9? It collapses the grey thermo, and the next available digit is a 3, forcing 321 into the rest of the pink thermo. That holds true whatever value you put on the end.
Did he say sh** at 31:00? 😂
Alright, time to work out some half time nerves with a sudoku!
Everyone, you CAN do the miracle killer sudoku!!!! It's amazing, and it's not nearly as difficult as a lot of the other ones on this page, quite approachable.
42:37 for my time... I think. I should do it again because I'm uncertain about when I unpaused it at the right time.
This'll separate out the football-phobes!
43:26!! Proud of that time...
I would like to See your reaction of Mark solving puzzle and Mark reaction of you solving puzzle, it might be two different puzzles. Thats not matter. Thanks.
Rules 3:09
Let’s get cracking 4:19
@10:58 Where 1 goes in box 3? only one place R1C6.
I just listened to your interview on Formscore, which was awesome, and you mentioned that no one ever talked to Mitchell Lee about The Miracle, and I'm wondering if you would ask him about doing a setting video for it? I know the puzzle is a year and change old and miracle-style stuff has somewhat run its course, but to me there's no reason why you can't revisit a legendary old puzzle from time to time in the setting videos. Mitchell did that solving video for CtC once and it was great so I'd love to see him again. I would LOVE to know how he discovered the implications of that ruleset and how you could use it to lead the solver on a journey like that.
Bonus if you can get Aad Van de Wetering to do one for any of his hyper-minimalist masterpieces from 2020 that he used to churn out on the regular.
I have a question. At 16:40 Simon deduced r1c4 couldn't be 8 or 9, or 1 through 3, but only penciled in 4, 5 and 7 - not 6, which was also a possibility. Then at 32:45 deduced it couldn't be a 5, so you penned in the 7 believing it was the only option remaining. Can anyone help me deduce how to rule out 6 there?
At 16:06, Simon deduces that green is one of r2c7 or r2c8, so chosen from 45789.
If it were 6, then the 13green triple in box 1 means there can't be a 6 in box 3 on row 3.
Similarly r1c4 also rules out 6 on the end of the purple thermo in box 3 r1c9.
Then there is no way to place the 6 in box 3 at all.
Even though sudokus like this one appear to be far above my abilities (I try and come up with a few ideas that are terrible and ineffective compared to Simon's techniques), I at least am smart enough to appreciate how ingeniously Simon solves them. Obviously the setters deserve an enormous amount of credit too but it's only by seeing Simon's solution you can understand the brilliance of the what the puzzler setter created.
41:31 for me. Nice one today. Not extremely hard, but an enjoyable level of difficulty.
8:02 "What about this thermometer?" [purple in box 3+6] [continues to explain that it can't start too high because it otherwise runs out of digits] - This is much simpler: This thermometer has at least one blue digit on position 2 or 3, and the blue ones are at most 4 (as shown just before). So its bulb can be at most 3. (I guess that's what Simon also concludes, and even more, but without using the nice blue coloring he added before.)
15:05 "1 goes in those squares by Sudoku, and that means 1 goes in these squares by Sudoku. Seems slightly strange to say when solving a Sudoku, the logic you are doing is using the rules of Sudoku." - I guess one could say "because this row has/these rows have already a 1, and this box still needs a 1", but that's a bit long.
Could have limited R1C9 much earlier too. 5-8 all had to be on it somewhere, and every single spot on the thermo saw the corner either by region, column, or row. So from the start it had to be something that only appeared once on the thermo, ie 4 and 9.
@@aesheronanglvd3th309 I'm not sure that is true. The termo could easily have a gap, i.e. 4,5,7,8,9.
@@PauxloE This is why I just watch haha. You're right of course.
It took me some time but it was a stunning puzzle.
I think it would help if the online software removed pencil marks automatically like all the apps do. So many times myself, Simon or Mark, and I'm sure others, forget to remove a pencil mark when placing a digit which makes the solve take longer cuz you miss it. At least in a classic sudoku sense, ie placing a 5 would remove any pencil marked 5s that see that 5 that was just placed.
Has simon ever remembered to put the card with the link? 😂
Help, please, I missed Simon's leap of logic at the 16:50 mark...How did he come up with 457 in Cell 1 of Box 2??? How did 6 get excluded as a possible digit???
It was a matter of where that digit needed to appear in row 2.
It wasn't the 2 or 3 and couldn't be on it's own thermo or it's own box so it needed to be the same digit as in either r2c7 or r2c8 neither of which had a 6.
I get the sentiment behind not immediately Goodliffeing every thermo, but not pencil-marking a 7-digit thermo feels a little on the precious side to me, anything else that let you limit a bunch of squares to three center pencil marks each you'd do in a heartbeat...
Someday someone will figure out Simon's Achilles's heel and put a 9-length thermometer in a puzzle, he'll be unable to solve it because just putting in all the digits would technically be Goodliffing...
We will eventually bring Simon over to the dark side (pencil marking thermos). Every time he pencil marked a thermo he made progress. Every time he resisted, he got stuck.
And because he didn't think in terms of the thermos and their pencil marks there were several times he missed things that could have been resolved by just cleaning up the marks that he did make.
Found a good way to start at box 3. The thermos in box 3 and protruding into box 6 have to be 8 unique digits. That immediately placed 1s and 2s in box 3. Similar logic in box 7 later on.
Nvm. Simon found the same logic later on XD
I am so tempted to try to create a puzzle sudoku with less than 17 given cell elements, just to shake up the logic that you need at least 17 givens for a classic sudoku. This seems like it can't possibly work though. That and my general lack of setting skills keep me from being too serious in this temptation.
This puzzle was heavy!
I'm always amazed to see a no digit sudoku have a single possible answer
Classic Simon with that 4 :D
29 minutes into the video, colors cells Red. Proceeds to never use that information for the rest of the puzzle. Classic.
You might have a great market selling pillows (or T-shirts or mugs) that have specific sudoku puzzles featured on the channel. Not knitted, obviously, but perhaps you partner with some setters and feature a handful of puzzles.
Interesting how you take the time to highlight red, but once you start getting cells in red........you don't use it at all.
So frustrating. That break could have been done so much earlier right after placing 4 in box 2.
me whos been sat here staring at the 4 that goes in box 3 before he even puts it in knowing exactly where it goes cause otherwise r2 has no 4-
Simon really needs to remove colored things in grid after they are used up , because he comes up with a lot of great logic he shows with color. Then he doesn't look at it again because there is color everywhere in grid and most is no longer useful.
Simon's reluctance to pencil mark thermos is just... strange. I don't know at this point if he just refuses to as a joke, or if he believes it's a better viewing experience without, but I can say I really prefer them with pencil marks.
Based on more than 2 years of watching this channel, I think pencil marks actually hurt his ability to solve a puzzle.
I'm surprised he didn't include the bulb in that upper right region, as it's a nine square region that all see each other and it would have given him the 1 immediately.
The dark purple thermos in the app made this one unplayable for me. Please fix.
Wow some1 has subbed and notifications on AND spent time to click on this just 2 be a hater lol. Nice time spending dude! (Could be a bit too but like.. y lol it’s just a normal Simon trying to solve a puzzle 😂)
The consensus is it's a bot, but the question still stands - why?
They probably spent less time doing it than you did mentioning/replying to them. They're not worth the effort. Just call them "margin of error" of the voting system.
@@Nyarlah true I’m just bored 😂
Completed in 36m44s
i cant solve the extremes sodoku xix... any tips
The episode where we ask ourselves why we use colors at all if we aren't going to use them.
Simon came awfully close to Goodliffing
I think i heard him say shit at 31:00 :D
The first time i seen a Number-Number-color triple
You always say the numbers on a thermo rise ‘like mercury’ in a thermometer, but surely the analogy is more related to the numbers printed on a real thermometer that mark off the different temperatures increase from the bulb end.
I prefer the mercury analogy, it's more poetic. :)
The early logic was confusing. If instead you ask where 1 can go in box 3, you get a 'triple' of two oranges and 1 and the results up to ~15 minutes follows.
that was fun :)
Lol I read the thumbnail "by Bon Jovi"
Hmmm, Bon Jovi_al would be an interesting mashup!
47:25 Once again that's not THE way to solve the Sudoku. It was just A way to solve as you missed several things during the solve.
