Hi everyone, Knickolas here! I'm so happy to see this puzzle featured! The title is correct, I first had the idea for this puzzle forever ago in November of 2022. After some working about, I found a lot of really interesting logic revolving around the 4 "rugby ball" thermos, but I was never able to find a way to resolve it that did the break in justice. So I would take a break, work on another puzzle, come back to it and keep getting stuck. This cycle lasted for 2 years and saw a lot of failed iterations, until 1 day (after not thinking about the puzzle for about 5 months) where I set the finish within 10 minutes of opening it back up. It's funny how something so elusive for so long can just suddenly reveal itself on a whim like that! Hopefully this can serve as a testimony to not admit defeat when you get stuck on something, because maybe it just needs a little more time :) Thanks for the feature! It's always a joy watching you solve!!
Simon should have given it the obviously clickbait title of "Phistomefel DISPROVED!!!", as it has been said by some that only Phistomefel could put a 9 in the bulb of a thermometer ..... and obviously, you have proved the contrary!!
Goal achieved 😏👍👍👍 You did it justice 100%❗What an awesomely awesome creation. You started from a *cosmic-class* break-in and obtained a *cosmic-class* puzzle. Double-brained *Hiuztwaetiukaians* from the *Eptagalactic Federation* are talking about you on *Cosmic Tube.* I solved this gem in about *6 hours* and it was totally worth it. Unforgettable epic experience. 👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏
Anyone else chuckle when Simon pencil marked 578 on three cells of a thermo and proceeded not only to not use the thermo to disambiguate their order but resolved those three digits last of all using sudoku?
49:00 Has Simon forgotten his earlier logic about the doubled digit in the two-thermo boxes needing to be from 1234 here? 7 is never going to work on any of those bulbs regardless of what else is around it because a 7 in the bulb would need at least a 10 value at the tip and a doubled 1234 at most gives you an extra 8 value...
At 25:47 it is possible to green the bulbs and the non-thermo cells in box 2, 4, 6, and 8. We can't start with double 5 ever, and the lower doublers are all spoken for. That is a lot of green missing in the grid for 25 minutes.
This puzzle melted my brain. Kept thinking the lower bulb had to be doubled on its own thermo for some reason, and went down just about every possible incorrect path. 4+ hours to solve.
I finished in 307:17 minutes. This seems to be what doublers do to me. They make me run marathons. They make me do gauntlets. They try to mess with me. However, I persevered and made my way through my own personal nightmare. I kept getting stuck in a cyclical loop of trying to solve one part to end up looping my logic. I spent so long on the bottom boxes and I was finally able to make progress by first asking if r7c789 could be doublers. The answer is no as this forces 789 into r7c123, which it can't be. I then asked a similar question about whether r9c789 could be doublers. The answer is also no, but for surprisingly the same reason as the one before, although much harder to see. Doing that required to look at the 12 cage. The 28 pair was easy to see. The 36 pair was much harder, but did end in the same logic. That was super cool. Then, my nightmare began as I struggled to make progress for...a...long...time. After eternity, I finally asked a right question being if 1 could go in r7c8. This surprisingly breaks through a long chain using row 5. It would force 2 into r2c7 and r9c5 along with 1 forced into r5c2 and 4 into r5c1. This 4 forces a 2 onto r3c2. This now breaks as 2 has no place in box 2. I know that this is probably not the intended, but after going so long with no progress, I take what I can get. It still wasn't over, though. Another eternity passed, until I asked if 35 could be in the 8 cage. The answer was no, also because of row 5. I was so close to the end now. I had one more breakthrough, figuring out which one was 3 between r3c8 and r7c8. This shocked me again as the answer was row 5. If 4 was in r3c8, then 1 and 3 both have to exist in r5c2. Finally, I was free from my torment. This puzzle was really excellent and it is a shame that I found such crude solutions to it. The puzzle definitely deserved better than me. However, I am oddly proud of my dumb logic pathways. I am very excited to see how it should properly be done. Great Puzzle!
It felt like a hammerblow to the face, but in a good way. Then a period of recuperation, until the next blow, a very striking puzzle, that truly tests ones deductive abilities. Each step was like searching for the stepping stones over a rushing river in complete darkness. Probably the best puzzle I've managed to solve in the past 2 months.
Once I did totally the other way. I also started and found, the 2 possible doublers in box 3, but I moved on to the box 7,8,9 and when I understood, that the 1,2,3 thermo start cannot be on the upper thermo, but has to be on itself, so it is the doubler and the 24 killer box is all green. From there I got a 7 in the middle and 34 pair and it pretty much collapsed the moment I realized, that 3 has to be down there, so 1,2 move to the row 7 on box 9. Great puzzle.
Wonderfully set puzzle. Very hard, I thought, even after getting to grips with the rugby balls. I forgot options and constantly had to refer back to notes in order to not go astray. But none of that matters: the fact that this puzzle has a unique solution is quite remarkable. Kudos! And thank you Simon for your steadfast logic, it really helps.
I quickly got the 1-double 1 location from the doublers in box 1,3 5 taking away other possibilities. I then came to a screeching halt and watched Simon solve.
58:44 I think you could’ve done this doubling logic a lot earlier - box 4 and box 7 had an x wing style set of pencil marked ‘doubler’ digits, meaning the doubler for box 1 was definitely in r2c2 - and this would probably have made the logic at the bottom a little easier once you remove a lot of the pencil marked doublers around the grid
At 1:05:48, Simon notes that the "high digit" must be at the end of the thermo and pencils it into box 8. He then says "that does nothing," but he's wrong. That means the next digit down the thermo can't be 789, so it's a 56, and the next one's a 45. You can combine this with the end of the other thermo being a 456. So, the second and third digits of the bottom thermo in box 8 are from the set 123, where one of them is the doubler. This must be a 3 and a doubled 1 or 2. Going further, that bottom thermo can't be 2, 3, double-3, as there'd be no place for '4' in box 9. So, the thermo starts 1, double-1, 3. (And there can be no more ones in any bulbs.)
I'll never be clever enough to be properly useful in these kinds of puzzles, even if I were to win one of the Patreon competitions, but I do hope that whoever wins helps Simon with his scanning.
In end was very interesting Simon pencil marked 3 digits on thermo and then solved them by sudoku. When he knowed actually they are all normal digits and thermo forces their order so no sudoku needed there :D.
Yes, it's really frustrating that Simon refuses to pencil mark thermos, which leads to all sorts of detours and failures to see some pretty straightforward logic on his part.
I think I spent about 30 minutes trying to play with this myself before returning to the video. Something Simon said around or before the 34:00 mark must have cracked things open for me. (When I returned to this screen after solving the puzzle, that's about where I was.) Including the first 30+ minutes of staring and coloring, this took me about 161 minutes. When I compare this to the last puzzle I solved ("One Look Could Kill," found on this channel, 1,032 minutes), not half bad. 😅 ... and now, as I write out those times, I realize this means I've been sitting in the same spot for about two hours, looking at my phone (where I solve sudoku), when I should be drinking water, eating dinner, preparing for Christmas celebrations. Oops.
I love watching Simon’s brilliance with breaking in a puzzle until I can follow the logic. That said it was painful watching him validate that 1234 doubler had to go on a rugby ball and the 4 could never have been in box 3 when trying to determine which of the two options pencil marked was the doubler in the box. He sorted it out at 59 minutes in a much more complicated way than lower level solvers would have.
🎶Simon's dreaming of a three... cornered... Simon's dreaming of a three... cornered. All he's dreaming of the whole video long is a cor...nered... three. Marty Sears' themed idea follows. I can flesh it out if people want me to: 🎶 OH... Officer Kropki, I'm down on my knees, trying to whisper in German and get cornered threes, We're not Schrodingered killers, for that idea stinks, deep down inside us we love Finkz, (we love Finkz...) (We love Finkz, we love Finkz, we love Finkz, we love Finkz, deep down inside us we love Finkz...
At 1:20:00 there's a useful 45 pair in box 4 that Simon overlooks. That stops r4c1 from being 4, makes it a 3 with a 2 below it on the thermo. I solved it in just under four hours, either side of a night's sleep.
Hey, Simon. Around 53:00 you decide that 8-7 cannot be 2, however it seems it could be 2 if the other bulb is 3. Then there would be a 3 in 7-6 and a doubled 2 in 9-4. It does break the cage in box 9, though.
I think he is using the fact that he already knows that R8C3 is the doubler in box 8 (because it's on its own thermo by sudoku) to rule out a 2 in R8C7 being doubled in that same box as well
Well, if there is only one doubler in the cell then if there is doubler on lines on position where it matters it can be only in 4 places, and there are only 4 pairs of lines. In addition doubler would be unlikely at the start of that lone additional line, because it would break principle of only one doubler per box. I wonder if the should state that "sums in cells are not affected by doublers" Simon wouldn't be forced to run around in circles.
Around 47 minutes in, you forgot your own conclusion from earlier: You know that boxes 2, 4, 6, and 8 contain the doublers for their respective low-valued cells. So you can't put 7 on any of the bulbs: To do so would be to say that it is the lower bulb of its pair, which it cannot be because that would require two doublers on the other thermo!
Monkeyed with it by myself for awhile. It's somewhat interesting - but I think if I could solve it in 2 years that would be a reasonable mathematical accomplishment. I'm sure I'll watch the video for a couple seconds and Simon will ask the perfect question or explain something and then newly armed with some piece of logic the puzzle will unravel in a couple hours.
Simon. If you can't do the puzzle, then OF COURSE you don't have to do all those messages again! Just make a cut, I'm sure nobody will mind at all. And actually, we *want* to hear about any failed attempts - you could even link to the puzzle that you got stuck on to give ambitious viewers something to chew on!
Didn't Simon get lucky on this solve? At the beginning of the puzzle Simon asserts that the bulbs of a rugby ball thermo must have unequal value (A must be greater than B); even though one bulb could be a ONE doubler and the other bulb could be a TWO natural, which means the bulbs are of equal value. He went on to use this (invalid) assertion to then assert any doubler in a Rugby gall 3x3 must be along one of the two bulbs. And this second assertion was then used to make the third assertion that a rugby ball bulb cannot be a doubler. Is this a flaw in the logic of the puzzle? Did Simon get lucky? Am I missing a piece of logic that corrects for my misunderstanding?
regarding the second assertion-each row, column, and box contains exactly one doubler, so if a doubler was on one of the bulbs, the doubler inside the box between them must fall along the length of either thermometer, and never in the middle
I know on mobile (Android) you need to press and hold a colour until the input panel changes (colour buttons get a white outline), then touch the colour you want to amend. That brings up a pop-up window that allows you to adjust that colour. On PC I think you have to double-left-click a colour (?), but I'm not a PC just now to confirm.

R8C3? It's identified as being in the bottom of box 8 by sudoku. That means it's on its own arrow. That means that has to be doubled. Simon's earlier logic was to identify that boxes 2,4,6,8 contain 1,2,3,4 doubled.
Just to clarify more. The lowest of the 2 bulbs has to allow 6 values higher than it to appear on the 6 thermo positions in the box between them. This limits the max to 4. Also, the lowest of the 2 has the be the one that is doubled. It cannot go in its own row, and it cannot go in the other thermo because it would be lower than the bulb we've just said is higher. It has to repeat on its own themo. That geometric logic maps to all 4 such boxes. Once you identify the doublers to exist in exclusively one row or column in these boxes you can always pencil in 1234 to the linked bulb.
@@mattconco I can't remember if it was disproved or not, but there are a few situations where the doubler could go on the opposite thermo of the rugby ball. If it was a 2-3 on the bulbs, the doubled 2 could go after the 3, and the 3 could go after the 2. The same is true for 3-4, 3-5, and 4-6, all of which are potential bulb pairs.
@@markp7262This ends up being the case in all but box 8. The doubled bulb digit ends up being on the opposite thermo. (This caught me out during my solve because I wrongly assumed they had to be on the same thermo.)
Honestly wish Mark had done this one instead. Simon's obstinate refusal to pencil mark thermos made him unable to see so many scenarios that were actually pretty straightforward.
Gave up on BooglelgooW (as it was given, I think with 'L's not 'I's)... as my head couldn't realise that the line entering the fog and the line exiting it were not the SAME line. Spoiler is on here, not the actual puzzle.
Spent a half hour treating the thermos as arrows and thinking that since the minimum in boxes 2, 4, 6, and 8 was 21 that there had to be doublers on one for each of boxes 1, 3, 7, and 9. Should probably read more carefully!
02:05:42 seconds for my time. That was a beautiful but really hard puzzle. Finding how those thermos are meant to work was really difficult. But mostly, I thought the puzzle gave no clue on where to look for the next step and some of the logic was really hard even after the break-in. Ruling out the 25 pair from the 12 cage was really difficult for instance, as well as ruling out the 2 from the bulb in r7c8. Very very nice puzzle anyway. I can't fathom how someone can get to settle this. Kudos for the setting and kudos for the solve while explaining the logic!
At 01:07:40, there is an easier way to disambiguate the 12 pencilmark in the bulbe from box 7, with no bifurcation, by asking where can 4 go in box 8? Let's ask what goes in middle row in box 8 ? Two of the digits 789 and the 1 or 2 that doesn't go in the bulb, by elimination. So 4 can't go there. Can it go on row 7? It's a normal thermo, so 4 can't repeat on the thermo, but 4 in box 9 is limited to row 7 or to r8c7 which is the bulb of the thermo. All these cells see the thermo in row 7 box 8, so 4 can't go in row 7 in this box. 4 then has to go on row 9. Can 2 be the doubler in box 8? It would then have value 4, but that's impossible since there is already a 4 somewhere on the thermometer. That makes it impossible for the doubler to be a 2, therefore the doubler is 1. I think that was a brilliant piece of logic that Simon's (valid) explanation somehow bypassed.
Hi everyone, Knickolas here!
I'm so happy to see this puzzle featured! The title is correct, I first had the idea for this puzzle forever ago in November of 2022. After some working about, I found a lot of really interesting logic revolving around the 4 "rugby ball" thermos, but I was never able to find a way to resolve it that did the break in justice.

It's funny how something so elusive for so long can just suddenly reveal itself on a whim like that! Hopefully this can serve as a testimony to not admit defeat when you get stuck on something, because maybe it just needs a little more time :)
Thanks for the feature! It's always a joy watching you solve!!
Tis the season for a puzzle from good ol' Saint Knickolas! Even has a Christmas theme with Simon's Coloring.
Wow, isn't it funny how often the way to solve a problem is to let it go for a while! Congrats on a really great result!
Beautiful (and very challenging) puzzle. I always love it when Simon takes on a really challenging puzzle like this one.
Simon should have given it the obviously clickbait title of "Phistomefel DISPROVED!!!", as it has been said by some that only Phistomefel could put a 9 in the bulb of a thermometer ..... and obviously, you have proved the contrary!!

Can we start a petition to get Simon a good light for his room for these long British winter nights? 😀

Simon, historically: 'You can't put nine on the bulb of a thermo'
Knickolas: 'Hold my doublers'
I like that it says values may repeat in a cage only for there to be no doublers in them in the end 😂
It felt like a hammerblow to the face, but in a good way. Then a period of recuperation, until the next blow, a very striking puzzle, that truly tests ones deductive abilities.
Each step was like searching for the stepping stones over a rushing river in complete darkness. Probably the best puzzle I've managed to solve in the past 2 months.
Oh that was a beast of a puzzle! Thank you so much for never giving up on it. The sheer brilliance of the “in” just blew my husband and me away!
I spent 20 mins on the puzzle and could only figure out which cells in box 3 can't be doublers. Worth the 90 mins I spent watching this video.
“Doubler doubler, nori nori”? No, it’s “Doubler doubler, toil and troubler”!
Once I did totally the other way. I also started and found, the 2 possible doublers in box 3, but I moved on to the box 7,8,9 and when I understood, that the 1,2,3 thermo start cannot be on the upper thermo, but has to be on itself, so it is the doubler and the 24 killer box is all green. From there I got a 7 in the middle and 34 pair and it pretty much collapsed the moment I realized, that 3 has to be down there, so 1,2 move to the row 7 on box 9. Great puzzle.
I should have known some setter would find a way to break the maxim "You can put a '9' in the bulb of a Thermo"
Wonderfully set puzzle. Very hard, I thought, even after getting to grips with the rugby balls. I forgot options and constantly had to refer back to notes in order to not go astray. But none of that matters: the fact that this puzzle has a unique solution is quite remarkable. Kudos! And thank you Simon for your steadfast logic, it really helps.

Oh xmas 3 ohxmas 3, how lovely are your cages

Etc.
58:44 I think you could’ve done this doubling logic a lot earlier - box 4 and box 7 had an x wing style set of pencil marked ‘doubler’ digits, meaning the doubler for box 1 was definitely in r2c2 - and this would probably have made the logic at the bottom a little easier once you remove a lot of the pencil marked doublers around the grid
15:59 “Let’s say that A is greater than B”.
Perfectly logical in Simon-world, where water is yellow and land is blue 😂
At 1:05:48, Simon notes that the "high digit" must be at the end of the thermo and pencils it into box 8. He then says "that does nothing," but he's wrong. That means the next digit down the thermo can't be 789, so it's a 56, and the next one's a 45. You can combine this with the end of the other thermo being a 456. So, the second and third digits of the bottom thermo in box 8 are from the set 123, where one of them is the doubler. This must be a 3 and a doubled 1 or 2.
Going further, that bottom thermo can't be 2, 3, double-3, as there'd be no place for '4' in box 9. So, the thermo starts 1, double-1, 3. (And there can be no more ones in any bulbs.)
No cage requires doublers. It is difficult to imagine how to even start❗ 🤔
Very interesting challenge‼😏👍👍👍
The rules say values on thermometers increase from the bulb end, should that be strictly increasing?
I'll never be clever enough to be properly useful in these kinds of puzzles, even if I were to win one of the Patreon competitions, but I do hope that whoever wins helps Simon with his scanning.
why does simon keep forgetting his rule he brilliantly discovered that boxes 2,4,6,8 can only have low number doublers :) !?!?
In end was very interesting Simon pencil marked 3 digits on thermo and then solved them by sudoku. When he knowed actually they are all normal digits and thermo forces their order so no sudoku needed there :D.

66:52 for me. What a crazy puzzle, really enjoyed it!
I love watching Simon’s brilliance with breaking in a puzzle until I can follow the logic. That said it was painful watching him validate that 1234 doubler had to go on a rugby ball and the 4 could never have been in box 3 when trying to determine which of the two options pencil marked was the doubler in the box. He sorted it out at 59 minutes in a much more complicated way than lower level solvers would have.
🎶Simon's dreaming of a three... cornered... Simon's dreaming of a three... cornered.
All he's dreaming of the whole video long is a cor...nered... three.
Marty Sears' themed idea follows. I can flesh it out if people want me to:

At 1:20:00 there's a useful 45 pair in box 4 that Simon overlooks. That stops r4c1 from being 4, makes it a 3 with a 2 below it on the thermo.
I solved it in just under four hours, either side of a night's sleep.
This puzzle was ABSURD. And absolutely brilliant.
Hey, Simon. Around 53:00 you decide that 8-7 cannot be 2, however it seems it could be 2 if the other bulb is 3. Then there would be a 3 in 7-6 and a doubled 2 in 9-4. It does break the cage in box 9, though.
I think he is using the fact that he already knows that R8C3 is the doubler in box 8 (because it's on its own thermo by sudoku) to rule out a 2 in R8C7 being doubled in that same box as well
I can't believe how hard it is for me to stop thinking the digits sum up to the value of the bulb because I'm so used to arrows.
Well, if there is only one doubler in the cell then if there is doubler on lines on position where it matters it can be only in 4 places, and there are only 4 pairs of lines.
In addition doubler would be unlikely at the start of that lone additional line, because it would break principle of only one doubler per box.
I wonder if the should state that "sums in cells are not affected by doublers" Simon wouldn't be forced to run around in circles.
Around 47 minutes in, you forgot your own conclusion from earlier: You know that boxes 2, 4, 6, and 8 contain the doublers for their respective low-valued cells. So you can't put 7 on any of the bulbs: To do so would be to say that it is the lower bulb of its pair, which it cannot be because that would require two doublers on the other thermo!
What a challenging puzzle. I made repeated mistakes for an hour before I was able to enjoy progress.
Monkeyed with it by myself for awhile. It's somewhat interesting - but I think if I could solve it in 2 years that would be a reasonable mathematical accomplishment. I'm sure I'll watch the video for a couple seconds and Simon will ask the perfect question or explain something and then newly armed with some piece of logic the puzzle will unravel in a couple hours.

And this second assertion was then used to make the third assertion that a rugby ball bulb cannot be a doubler. Is this a flaw in the logic of the puzzle? Did Simon get lucky? Am I missing a piece of logic that corrects for my misunderstanding?
If a bulb was a 1 doubler, where will you put the 1 in that box?
regarding the second assertion-each row, column, and box contains exactly one doubler, so if a doubler was on one of the bulbs, the doubler inside the box between them must fall along the length of either thermometer, and never in the middle
@@grubbzor Ah, perfect! Thank you.
Is there a reason why a thermometer is in front of any cell colouring, but the bulb isn't?
Does anyone have a link for how to edit colors in sudokupad; to customize your palette?
I know on mobile (Android) you need to press and hold a colour until the input panel changes (colour buttons get a white outline), then touch the colour you want to amend. That brings up a pop-up window that allows you to adjust that colour.
On PC I think you have to double-left-click a colour (?), but I'm not a PC just now to confirm.
Did you see the room turning darker and darker?

I found it really amusing that no cages had doublers.
Not gonna lie, you lost me on this one Simon. Just couldn't keep up. Still had a great time though!
I started 4 times and 4 times a went stuck because I was not strickt enough with scrutinizing the possibilities. The 5th time I managed to solve.
At 49:49, I don;t understand why Simon limits R6C3 to 1234. Why not including 56 too?
R8C3? It's identified as being in the bottom of box 8 by sudoku. That means it's on its own arrow. That means that has to be doubled. Simon's earlier logic was to identify that boxes 2,4,6,8 contain 1,2,3,4 doubled.
Just to clarify more. The lowest of the 2 bulbs has to allow 6 values higher than it to appear on the 6 thermo positions in the box between them. This limits the max to 4. Also, the lowest of the 2 has the be the one that is doubled. It cannot go in its own row, and it cannot go in the other thermo because it would be lower than the bulb we've just said is higher. It has to repeat on its own themo. That geometric logic maps to all 4 such boxes. Once you identify the doublers to exist in exclusively one row or column in these boxes you can always pencil in 1234 to the linked bulb.
@@mattconco I can't remember if it was disproved or not, but there are a few situations where the doubler could go on the opposite thermo of the rugby ball. If it was a 2-3 on the bulbs, the doubled 2 could go after the 3, and the 3 could go after the 2. The same is true for 3-4, 3-5, and 4-6, all of which are potential bulb pairs.
@@mattconco Oh, I got it now, because the thermo could not contain 789, the bulb is certainly 5 or 6. I was not awake enough I guess.
@@markp7262This ends up being the case in all but box 8. The doubled bulb digit ends up being on the opposite thermo.
(This caught me out during my solve because I wrongly assumed they had to be on the same thermo.)
Simon can we get some more tapa puzzles. It’s been a while
Honestly wish Mark had done this one instead. Simon's obstinate refusal to pencil mark thermos made him unable to see so many scenarios that were actually pretty straightforward.
I'm not sure if I'd prefer Mark solving it under 23 minutes. Watching Simon going in circles until I saw sunrise was interesting.
Yeah... I'm not getting this by myself any time soon.
19:25 - Recall that Piet Mondrian artwork he showed us at the start of the video...?
I’m seeing perhaps both versions of Phistomefel coming into play.
I got past the secret age corner digit song years ago. Just thought of that.
Gave up on BooglelgooW (as it was given, I think with 'L's not 'I's)... as my head couldn't realise that the line entering the fog and the line exiting it were not the SAME line. Spoiler is on here, not the actual puzzle.
Looks like someone created a 6 out of 5 star sudoku.🤪
It’s more of a violet than dark blue. Dark blue is indigo, instead of violet.
Wow, that _was_ a hard one.
Am I going crazy. Isn't that dark blue actually purple?
And this song of mine

Good evening
ok not getting this puzzle...
Why can't I see cage values in dark mode anymore? It just shows a white square instead of the number.
covid19 was started somewhere near to 2020 beginning so it is nearly 5 years already
Spent a half hour treating the thermos as arrows and thinking that since the minimum in boxes 2, 4, 6, and 8 was 21 that there had to be doublers on one for each of boxes 1, 3, 7, and 9. Should probably read more carefully!
Well hello hello
Hello
02:05:42 seconds for my time. That was a beautiful but really hard puzzle. Finding how those thermos are meant to work was really difficult. But mostly, I thought the puzzle gave no clue on where to look for the next step and some of the logic was really hard even after the break-in. Ruling out the 25 pair from the 12 cage was really difficult for instance, as well as ruling out the 2 from the bulb in r7c8.
Very very nice puzzle anyway. I can't fathom how someone can get to settle this.
Kudos for the setting and kudos for the solve while explaining the logic!
At 01:07:40, there is an easier way to disambiguate the 12 pencilmark in the bulbe from box 7, with no bifurcation, by asking where can 4 go in box 8?
Let's ask what goes in middle row in box 8 ? Two of the digits 789 and the 1 or 2 that doesn't go in the bulb, by elimination. So 4 can't go there.
Can it go on row 7? It's a normal thermo, so 4 can't repeat on the thermo, but 4 in box 9 is limited to row 7 or to r8c7 which is the bulb of the thermo. All these cells see the thermo in row 7 box 8, so 4 can't go in row 7 in this box.
4 then has to go on row 9.
Can 2 be the doubler in box 8? It would then have value 4, but that's impossible since there is already a 4 somewhere on the thermometer.
That makes it impossible for the doubler to be a 2, therefore the doubler is 1.
I think that was a brilliant piece of logic that Simon's (valid) explanation somehow bypassed.
