@Ella Enchanted I'm not sure there's a good way to colour for colourblindness if you're using all the colours though, they get so mixed up around the grid.
@@sageandsound While that is definitely an issue, taking steps to make sure that at least initially that isn't an issue would make it easier overall, I'd imagine. That plus the verbal explanation and the written #s allows for a nice balance to help keep things straight. While I'm not colorblind, I know the particular shade they have for orange makes it difficult for me when Red and Orange are directly next to each other. If they don't start out that way, however, it's much easier to keep them straight when we do get to boxes where they're adjacent than if it starts close together and then gets separate.
Just noticed a two-cell renban on a domino is functionally equivalent to a white kropki the same way a two-cell thermo on a domino is functionally equivalent to an inequality symbol or a two-cell killer cage with a 5 or 10 is a V or X. Not sure why but these little isomorphies are fascinating to me whenever they come up.

Fawlty Towers references are always welcome. Mrs. Richards, brilliantly played by Joan Sanderson. Absolutely love that episode. Has the best scene of the whole series "Well, may I ask what you were expecting to see out of a Torquay hotel bedroom window? Sydney Opera House, perhaps? The Hanging Gardens of Babylon? Herds of wildebeest sweeping majestically" "You can see the sea, it's over there between the land and the sky". Still makes me laugh every time and I have seen that episode dozens of times.

Very clean solve. A point on colours, I don't think you should go back and colour the grid when the puzzle is complete. The partially coloured completed grid demonstrates the solution path nicely. Rather than spending the time to fill in the colours when they no longer are needed for the solve, use them to give a recap of the solve at end of the video.
One of the most incredible puzzles I’ve seen. Geez. And don’t let the pencilmarking error down column 9 take anything away from the solve, it’s brilliant as well. What incredible logic and geometry. The concept and the execution. Beautiful all around.
Amazing sudoku, that was one of the most entertaining ‘colouring’ solves by miles! I loved the idea to relate the thermos to each other using the combination of renbans and thermometers which share their endpoints and how it all led to the final reveal in box 5. Exceptional setting, many thanks Cane_Puzzles and thanks Simon for the solve video. :)
Thanks Simon for showing us the beauty of this puzzle. I am amazed at how quickly Simon figured out the increasing order among the three 4 digit ThermoRenban combos. Even the 2 digit Renban in the middle box was a beauty.
21:50 Did Simon get lucky, or is there a reason the colors of r6c7 (purple) and r7c8 (red) can't be swapped? At this point in the puzzle it seems possible.
No, sudoku rules mean red has to be in one of the last three cells of row 7, otherwise there's nowhere else to place it in box 9, and you can't duplicate a colour on a renban.
"I know nothing" makes me think of Sergeant Schultz from Hogan's Heroes. What a brilliant puzzle by Cane_Puzzles. Smallish Thermos/Renbans all disambiguated by a tiny Renban in box 5. Wow! As Simon often says to the constructor...."Take a bow".
My best solve ever. Figured out the pattern of the thermo/renban combos quickly which led to a 22:06. I have never come CLOSE to beating one of Simon's times by that much. This channel makes you better at solving logic puzzles. Period.
@@alanclarke4646 Starting with the thermo in box 3, you can see that the numbers drop by one each time you rotate over one thermo counterclockwise. So that one that starts in box 3 has to start with at least 5. But if you try starting it with a 5 you see that the shortened thermo in box 9 prevents you from putting 4 consecutive digits on that associated renban line. The only option left is to start the thermo in box 3 with a 6 (which is the highest it can be). Then rotate counterclockwise to the other thermos and drop each starting point by one number.
In the beginning it struck me that the 4 thermo/renban boxes are placed symmetrically. Only the one in box 6&9 deviates from the other 3 with its 3-cell thermo. Usually a puzzle creator will prefer a complete symmetrical setup but here that is not possible: every 4-cell thermo forces the next one (CCW rotation) to be lower. So with 4 of them that would result in an Escher staircase.
I thought that at first, but actually after a full rotation, there's enough separation that there wouldn't be a clash. In the finished solution, you could have 2345 or 1234 on the lowest, and 6789 on the highest. My guess is the setter tried this, and it either couldn't be made to work, or it made the puzzle too easy. It certainly made the logic a bit more interesting.
Funny that Simon's apology for his mistake includes the the feeling that he was doodling on some art given the current story about the security guard doodling on the art he was supposed to be watching over. We forgive your rare lapses Simon. All too relatable.
47:32 for me - this was tricky but I figured out how the numbers were packed together. I bifurcated once, it didn't give me the answer but while doing that I saw some logic I didn't work out and could continue logically. I feel really good about myself for working through it and not just watching Simon do it.
Simon needs to stop comparing the quality and beauty of the puzzle he is working on each day to the puzzles he was working on in the recent past, because they are all singular works art, where each one should stand alone on its own mountain top, surrounded by infinite valleys of computer generated drivel... Long live hand-crafted artwork logic-puzzles.
Excellent puzzle a real joy Simon was doing a great solve until he had to resort to sudoku, a fair bit later than myself tbh. I love this type of tight and intelligent creation, very clever with some nice touches
Ahh, good ol' Farty Towels. Haven't seen it in decades, but still so hard to believe that everything I remember is from a show that only had 12 episodes.
Not that I'm really surprised by the quality of Simon's references by now, but "I know nooothing" was just excellent :D Oh yeah, and brilliant puzzle too!
I believe that r6c8 and r7c7 are the same, because the middle digit in the thermo has to appear on the renban. I noticed this immediately (when Simon dismissed the shape, which he was right to do as that was all it said at the moment). But at 19:22 it removes red from both those cells.
Very fun puzzle, figuring out the initial logic was very fun, although as usual I got stuck on the regular sudoku later on, lol. I'm proud to have gone from taking a whole day to solve a puzzle to doing it in comparable times to Simon's (understandably slowed down) solve after about one month of being a fan of the channel.
Remarkable puzzle. And ah, Simon's glorious coloring "for the fans" at the end, naturally failing to see that multicolored 6-7-8 triple. Love you, Simon!
We just need one more color though. I've used the zero, or green x or green 0, but a color would be better. Maybe I'll use the green x as the unkown rather than light grey.
I think the white button should function as a white button rather than just a delete-colour button. That way you could use white properly as a colour and if you needed to put another colour in the square it would be half white.
How about this? 32:56 1.r5c7 is gray in column 7. 2.there is gray/black/purple is box6,these 3 consecutive digits should be in r4c4,r4c5,r4c6 3.r4c6 is gray and r5c5 is gray minus one=1
Resolving middle line was suprisingly clean and easy as done by Simon, but I personally went for different approach. Once I had 8 colors I decided to mark them as 1-8, and keep the last digit as 0 - remembering that 0 is either before 1 or after 8. Works nicely if it takes you a while to resolve middle.
I just put in a single candidate for each cell, I can’t do it as systematically as Simon, but doing that did reveal the nature of the constraint we are dealing with in the puzzle.
Started screaming in my head from 37:27 box 8 via row 8. 38:00 Sigh. Brilliant yet Blind. He is "When all else fails do Sudoku" when he needs to be "Sudoku every number you put in".
Could anyone help with the logical basis that the Renban/Thermo in box 6/9 cannot have Red at the end of the thermo? Simon appears to just know why it is and I cannot figure it out
Very neat. Took me rather longer than Simon to crack the central line, and I ended up disambiguating the colours when I suddenly had a 123 triple in column 5.
I'm sorry, but coloring the digits at the end does not placate me. When I discovered the top digit on the thermos had to be 9, I resisted filling out those numbers and instead finished coloring the grid doing sudoku on the colors. Then I filled in the numbers with nine double-click moves. That is always my goal on color based sudoku solves.
Not having 9 colors is a bit of an oversight ;) I suggest the following colors generated to be the most distinct: Text - darkblue #00008b 1 - darkgreen #006400 2 - maroon3 #b03060 3 - orangered #ff4500 4 - yellow #ffff00 5 - burlywood #deb887 6 - lime #00ff00 7 - aqua #00ffff 8 - fuchsia #ff00ff 9 - cornflower #6495ed
You missed a bit of magic on r2c3 and its effect on box 2. Once you have most of the right side of the box colored in, r2c3 is equivalent to r3c5. This is because it cant be consecutive with itself (r1c4), it can’t be in the same row as itself (r2c4), and it can’t be higher than itself on its own thermo(r3c4). That allows you to put 3 into both cells by matching up pencil marks
Took me a solid 60 minutes to do the coloring, but then I got sidetracked with the small thermo at the bottom left, instead of paying attention to the diagonal band in the center! Still, 90m45s and I am quite okay with that.
38:12 When you put the 68 pair in box 9 you overlooked that r6c9 already was a 68 as well since it saw the 7 in r6c5. I was on edge the rest in hopes you finding the unmarked 3 in c9. Glad you figured that out in the end. What an amazing puzzle and it's good to see that even you make mistakes sometimes ;)
The sad thing is that he even remarked that he had a 678 triple. He then forgot to remove the 7 from the 47 cell, and accidentally included the 4 in his pencil marking.
I started out by mixing up thermometers with arrows, which actually led to some cool logic (every four-cell 'arrow' has to have a 1 and a 2 on the non-renban cells, which allowed for some digits to be placed in the middle box). I realised my mistake before too long though :(
Great puzzle. I want to take a second to thank Cane_Puzzles for disambiguating the number-color relation fairly early before the final cleanup. It made filling in the grid a lot less mechanically challenging. (I'm not trying to call anyone out by name on this. Especially not twototenth.)
Really nice puzzle. Simon could have kept going with the coloring I think and doing more pairs/triples to help himself out. Not sure why he just did the one blue/yellow/orange triple in box 6 and then refused to do any others.
I'd to thank you for NOT coloring during the solve once you resolved the colors to digits. Before you resolve the digits, coloring makes total sense, but once you have real digits, coloring for its own sake often makes the incomplete puzzle harder to scan.
my solve time is 36 minutes. its a fun puzzle with weird logic which I liked. what helps is to color everything because 3 thermometers have to be consecutive and the renban lines next to the thermometers makes some beautiful logic where you can use 6 different colors, that represent 6 different digits, along the thermo/renban lines. then you use the second digit of box7-8 thermo, which has to be placed on the renban in box9. and that digit will get pressured a lot which will result in getting a lot of other digits because the thermos/renban combo is consecutive and really strong. after that its normal sudoku and using the other smaller renban lines/thermometers. in short: it was a fun solve and I recommend you give it a try
Can someone help me? When Simon was doing the lower right renban and thermo he figured that red was on the renban, but didn't consider it for being on r6c7, which it can! How do you disambiguate that if you consider it? Edit: Never mind, I figured it out like 2 seconds after posting :')
I kept confusing myself with the central box on the line and had to watch through your solve to get my mind to finally click (which then wound up seeming so obvious once you pointed it out)
FTL (far too long lol) for me. Quite a beautiful puzzle. For some reason by puzzles like this one I like to work fully in colours and no numbers.even if I know the numbers already. There is something satisfying to double tap all colours and full on the numbers all in one go.
Simon (38:17): "Ooh, I've got a 6-7-8 triple here... so in this column I need 1, 4, *7,* and 9" *pencil marks 149 in r1c9 and not 3* 40:47 "now that's a 4 by sudoku..." *Ironically mistypes 3 but then "corrects" it to 4* Pays for his mistake at 41:03 XD Glad to see you're human after all!
Hey, I have a question about the Sven's SudokuPad app: You put the link for the puzzle into the description and it leads to the website which has the same interface as the app. There is a "Import Puzzle" Function in the app, but unfortunately I haven't been able to successfully to import any sudoku. I wonder if somebody was able to use that function and could help me out, because I like solving on the phone the most and I would also like to save the puzzles on the app.
You follow the link to the puzzle in the web version of the software and at the top there's a link that says "play in sudoku pad". That goes to a landing page that includes another button plus some links to the app stores to download the app, if you click the link on that landing page it should open the app on your phone and prompt you to save the puzzle after which you can play it offline in the app.
@@AlRoderick Great, thank you very much it worked! I always tried to copy the Weblink and paste it in the app but it never worked out. Finally I can save and solve the puzzles on my phone, thanks again! :)
I probably would've called this puzzle see saw - when I'm looking at the purple lines with the thermos that's what I see. But absolutely love the look of this.
Why could simon exclude that the renban in box 5 is 8 & 9 with green in the Center of box 5 becoming an 8? Probably this would lead to some trouble later, but at this point I did not get this deduction ?
That was very cool. I got bogged down in the middle for a while until I managed to lock a triple 678 into box 6, that was my tipping point where I finally resolved the chain of pairs and everything cleared up
Now he needs to do a follow up video, correctly coloring in the 6, 7 and 8 on the right hand side to please my my sense of order. Because now the coloring made it worse instead of resolving the chaos. XD
The highest number on the thermos (in r3c6) must appear in box 8 in column 5, because we know that it isn't along the thermo in box 8. In box 5, it must be in column 4. That number must be either an 8 or a 9, and whichever it is it cannot be on either spot on the line in box 5. Therefore the line must be a 12 pair.
Thank you! Finally you make a minor mistake and have to back up a couple of cells. I'm not a total incompetent for making that sort of mistake so often!
I've seen solvers, not just Simon, consistently do logic & eliminations just to disregard all their work by simultaneous fill of remaining triples & quads. Perhaps I'm nit-picking, but this common tendency drives me batty. It is like we are reinventing the wheel and disregarding all previous logic, often hard won. There is no "efficiency" in such indiscriminate use of this computer function, especially when it hampers the path of the solve, as it often does. Usually Simon finds an alternate, more difficult path... but often that little tic stymies progress completely. If hand done, this pitfall would be rarer, I think. That said, I thoroughly enjoyed the approach Simon took to breaking in on this fascinating puzzle. The "error" occurred when pencil marking the triple in box 6, which then impeded logic on boxes 4 & 5. No big deal; he found another way. And finally addressed it when 6 was placed in box 9. But I could predict from the second he put 3 possibles in a bi-colored cell, the oversight was going to persist for most of the solve.
Agreed, and it's so easily fixed by entering the center marks, paring them down to match the corner marks, then removing the corner marks, rather than deleting everything then entering the n-ple
Bummer, I didn’t notice the problem with 2 in box seven. I mean this just proves what I said earlier, Simon is sure to solve it systematically. Color! He taught us how to use color, why don’t I think of it?
What really impresses me about this channel is the ability of the solvers to recover from the few mistakes they make. It looks a lot different when I make a similar mistake.
Not to detract, but I suspect there's a tiny bit of selection bias at play here too :)

I love how, to someone not familiar with these special case sudokus, this comment reads like the most extreme Star Trek technobabble.
The difference is that you can do a two-cell renban also diagonally, while kropki-dots usually don't work that way. So Renban is more powerful.

In the finished solution, you could have 2345 or 1234 on the lowest, and 6789 on the highest. My guess is the setter tried this, and it either couldn't be made to work, or it made the puzzle too easy. It certainly made the logic a bit more interesting.
Funny that Simon's apology for his mistake includes the the feeling that he was doodling on some art given the current story about the security guard doodling on the art he was supposed to be watching over.
We forgive your rare lapses Simon. All too relatable.
47:32 for me - this was tricky but I figured out how the numbers were packed together. I bifurcated once, it didn't give me the answer but while doing that I saw some logic I didn't work out and could continue logically. I feel really good about myself for working through it and not just watching Simon do it.
Haha LOVE the Fawlty Towers reference, poor Basil can't catch a break in that one
The old ritual of RickRolling ist still practiced here, how nice.
Simon needs to stop comparing the quality and beauty of the puzzle he is working on each day to the puzzles he was working on in the recent past, because they are all singular works art, where each one should stand alone on its own mountain top, surrounded by infinite valleys of computer generated drivel... Long live hand-crafted artwork logic-puzzles.
I’ve lost count of the number of times Simon has said ‘This is the best puzzle we’ve ever seen’ (or words to that effect)!
Excellent puzzle a real joy
Simon was doing a great solve until he had to resort to sudoku, a fair bit later than myself tbh.
I love this type of tight and intelligent creation, very clever with some nice touches
Ahh, good ol' Farty Towels. Haven't seen it in decades, but still so hard to believe that everything I remember is from a show that only had 12 episodes.
Not that I'm really surprised by the quality of Simon's references by now, but "I know nooothing" was just excellent :D
Oh yeah, and brilliant puzzle too!
Oh nice, I actually tried this one on LMG before and couldn't get anywhere, finally a tutorial lol
I believe that r6c8 and r7c7 are the same, because the middle digit in the thermo has to appear on the renban. I noticed this immediately (when Simon dismissed the shape, which he was right to do as that was all it said at the moment). But at 19:22 it removes red from both those cells.
Very fun puzzle, figuring out the initial logic was very fun, although as usual I got stuck on the regular sudoku later on, lol.
I'm proud to have gone from taking a whole day to solve a puzzle to doing it in comparable times to Simon's (understandably slowed down) solve after about one month of being a fan of the channel.
A crucial part of a puzzle that uses coloring is to preserve the point at which we no longer need it as part of the history of the solve.
41:56 ... I, too, loved solving this one.
Nice puzzle!
Remarkable puzzle. And ah, Simon's glorious coloring "for the fans" at the end, naturally failing to see that multicolored 6-7-8 triple. Love you, Simon!
Well dang. I didn't click on the link for the song yesterday, and now I wish I had.
You can use the pen tool to make an "O" when you need a 9th color. That's what I've been doing.
We just need one more color though.
I've used the zero, or green x or green 0, but a color would be better. Maybe I'll use the green x as the unkown rather than light grey.
I think the white button should function as a white button rather than just a delete-colour button. That way you could use white properly as a colour and if you needed to put another colour in the square it would be half white.
How about this? 32:56
1.r5c7 is gray in column 7.
2.there is gray/black/purple is box6,these 3 consecutive digits should be in r4c4,r4c5,r4c6
3.r4c6 is gray and r5c5 is gray minus one=1
Simon Destroys Rainbow, Solves Sudoku Puzzle
22:24 for me. Wow, I also loved this, what an incredibly clever idea for the break-in. That’s truly genius, what a great puzzle.
Resolving middle line was suprisingly clean and easy as done by Simon, but I personally went for different approach. Once I had 8 colors I decided to mark them as 1-8, and keep the last digit as 0 - remembering that 0 is either before 1 or after 8. Works nicely if it takes you a while to resolve middle.
Is it possible to adjust the green tint a bit more dark? It is hard for me to distinguish it from yellow :)
I just put in a single candidate for each cell, I can’t do it as systematically as Simon, but doing that did reveal the nature of the constraint we are dealing with in the puzzle.
The phrasing at 43:41 is the highlight of this puzzle. The bot should add that to the list of Simarkisms. 🤣
lol, I thought the same thing :)
I did It! It took me almost 2 hours, but I have managed to solve it. It was a great puzzle, there's no doubt about it!
Started screaming in my head from 37:27 box 8 via row 8. 38:00 Sigh. Brilliant yet Blind. He is "When all else fails do Sudoku" when he needs to be "Sudoku every number you put in".
Another new technique that is very enjoyable! I'm a fan of a multi-colored grid! (I also enjoy being Rick rolled - makes me laugh 😄)
Oops. I worked on this puzzle for 20 minutes thinking the thermos were arrows... I was making good progress, but eventually ran into problems. 😅
62:24
Lots of colouring highlighting some very pretty logic.
Honestly the start for this one was well beyond me but once the squares were sorted I was able to engage and follow it was brilliant
Could anyone help with the logical basis that the Renban/Thermo in box 6/9 cannot have Red at the end of the thermo? Simon appears to just know why it is and I cannot figure it out
Very neat. Took me rather longer than Simon to crack the central line, and I ended up disambiguating the colours when I suddenly had a 123 triple in column 5.
I'm sorry, but coloring the digits at the end does not placate me. When I discovered the top digit on the thermos had to be 9, I resisted filling out those numbers and instead finished coloring the grid doing sudoku on the colors. Then I filled in the numbers with nine double-click moves. That is always my goal on color based sudoku solves.
Not having 9 colors is a bit of an oversight ;)
I suggest the following colors generated to be the most distinct:
Text - darkblue #00008b
1 - darkgreen #006400
2 - maroon3 #b03060
3 - orangered #ff4500
4 - yellow #ffff00
5 - burlywood #deb887
6 - lime #00ff00
7 - aqua #00ffff
8 - fuchsia #ff00ff
9 - cornflower #6495ed
Omg I was looking at thermos as arrows. No wonder why I couldn't solve it.
You missed a bit of magic on r2c3 and its effect on box 2. Once you have most of the right side of the box colored in, r2c3 is equivalent to r3c5. This is because it cant be consecutive with itself (r1c4), it can’t be in the same row as itself (r2c4), and it can’t be higher than itself on its own thermo(r3c4). That allows you to put 3 into both cells by matching up pencil marks
That's three in the corner
losing... its pencilmark
Rick roll? Isn't that 8-track with quadraphonic sound?
Took me a solid 60 minutes to do the coloring, but then I got sidetracked with the small thermo at the bottom left, instead of paying attention to the diagonal band in the center! Still, 90m45s and I am quite okay with that.
I wish I got rick rolled yesterday... but I was apparently late to that party... Well, it's a good thing I listen to Rick's songs anyway.
It's a great day when the CTC video has an REM reference in it!! I love it!
My absolute favourite type of puzzle. A perfect mix of colours and numbers and you have to solve both!
38:12 When you put the 68 pair in box 9 you overlooked that r6c9 already was a 68 as well since it saw the 7 in r6c5. I was on edge the rest in hopes you finding the unmarked 3 in c9. Glad you figured that out in the end. What an amazing puzzle and it's good to see that even you make mistakes sometimes ;)
The sad thing is that he even remarked that he had a 678 triple. He then forgot to remove the 7 from the 47 cell, and accidentally included the 4 in his pencil marking.
I started out by mixing up thermometers with arrows, which actually led to some cool logic (every four-cell 'arrow' has to have a 1 and a 2 on the non-renban cells, which allowed for some digits to be placed in the middle box). I realised my mistake before too long though :(
Great puzzle. I want to take a second to thank Cane_Puzzles for disambiguating the number-color relation fairly early before the final cleanup. It made filling in the grid a lot less mechanically challenging. (I'm not trying to call anyone out by name on this. Especially not twototenth.)
I think this is beautifully constructed and enjoyed the solve.
Really nice puzzle. Simon could have kept going with the coloring I think and doing more pairs/triples to help himself out. Not sure why he just did the one blue/yellow/orange triple in box 6 and then refused to do any others.
I'd to thank you for NOT coloring during the solve once you resolved the colors to digits. Before you resolve the digits, coloring makes total sense, but once you have real digits, coloring for its own sake often makes the incomplete puzzle harder to scan.
my solve time is 36 minutes.
its a fun puzzle with weird logic which I liked. what helps is to color everything because 3 thermometers have to be consecutive and the renban lines next to the thermometers makes some beautiful logic where you can use 6 different colors, that represent 6 different digits, along the thermo/renban lines. then you use the second digit of box7-8 thermo, which has to be placed on the renban in box9. and that digit will get pressured a lot which will result in getting a lot of other digits because the thermos/renban combo is consecutive and really strong. after that its normal sudoku and using the other smaller renban lines/thermometers.
in short: it was a fun solve and I recommend you give it a try
Can someone help me? When Simon was doing the lower right renban and thermo he figured that red was on the renban, but didn't consider it for being on r6c7, which it can! How do you disambiguate that if you consider it?
Edit: Never mind, I figured it out like 2 seconds after posting :')
That's 3 in the corner!
I kept confusing myself with the central box on the line and had to watch through your solve to get my mind to finally click (which then wound up seeming so obvious once you pointed it out)
FTL (far too long lol) for me.
Quite a beautiful puzzle.
For some reason by puzzles like this one I like to work fully in colours and no numbers.even if I know the numbers already. There is something satisfying to double tap all colours and full on the numbers all in one go.
Simon (38:17): "Ooh, I've got a 6-7-8 triple here... so in this column I need 1, 4, *7,* and 9"
*pencil marks 149 in r1c9 and not 3*
40:47 "now that's a 4 by sudoku..."
*Ironically mistypes 3 but then "corrects" it to 4*
Pays for his mistake at 41:03 XD
Glad to see you're human after all!
Simon shows why we shouldn't trust pencil marks at the end.
Hey, I have a question about the Sven's SudokuPad app: You put the link for the puzzle into the description and it leads to the website which has the same interface as the app. There is a "Import Puzzle" Function in the app, but unfortunately I haven't been able to successfully to import any sudoku. I wonder if somebody was able to use that function and could help me out, because I like solving on the phone the most and I would also like to save the puzzles on the app.
You follow the link to the puzzle in the web version of the software and at the top there's a link that says "play in sudoku pad". That goes to a landing page that includes another button plus some links to the app stores to download the app, if you click the link on that landing page it should open the app on your phone and prompt you to save the puzzle after which you can play it offline in the app.
@@AlRoderick Great, thank you very much it worked! I always tried to copy the Weblink and paste it in the app but it never worked out. Finally I can save and solve the puzzles on my phone, thanks again! :)
This puzzle is exeptional amog exeptionals.
I probably would've called this puzzle see saw - when I'm looking at the purple lines with the thermos that's what I see. But absolutely love the look of this.
See saw? Do you mean bow saw? Cause that's all I can see.
Why could simon exclude that the renban in box 5 is 8 & 9 with green in the Center of box 5 becoming an 8? Probably this would lead to some trouble later, but at this point I did not get this deduction ?
Because green needs to be in the column in box 8.
Oh, yes! Actually quite obvious! However, I did not see it! Thx a lot!
That was very cool. I got bogged down in the middle for a while until I managed to lock a triple 678 into box 6, that was my tipping point where I finally resolved the chain of pairs and everything cleared up
Love the vids!👍🏻
Nice puzzle. 30:49 for me. But it would have been a bit quicker if I had given up colouring once I knew what each colour was!
Great puzzle. Thank you !!!
Great fun. Thank you!
Now he needs to do a follow up video, correctly coloring in the 6, 7 and 8 on the right hand side to please my my sense of order. Because now the coloring made it worse instead of resolving the chaos. XD
That's blue in the corner.. xd. Am happy that, with a tiny bit of coaching, I was able to solve this one
43:26 We always forgive you. You should do it to yourself. Don't forget: everybody makes mistakes.
What a colorful and fun puzzle!
Thank you
My second puzzle from this channel. It took me 'only' 180 minutes :D
39'29". Very cute. I used colors to represent sequential numbers: red was some A, orange was A+1, etc.
Sorry, at 10:30 or so..why can’t you use 5678 at the bottom? Or 6789? 🤔
Nvm… I see where the 2 would need to be
How do we know that the line in the middle box is a 12 and not an 89?
The highest number on the thermos (in r3c6) must appear in box 8 in column 5, because we know that it isn't along the thermo in box 8. In box 5, it must be in column 4. That number must be either an 8 or a 9, and whichever it is it cannot be on either spot on the line in box 5. Therefore the line must be a 12 pair.
That whole backtrack to see why I went astray thing happens in most of my sudokus.
Thank you! Finally you make a minor mistake and have to back up a couple of cells. I'm not a total incompetent for making that sort of mistake so often!
I've seen solvers, not just Simon, consistently do logic & eliminations just to disregard all their work by simultaneous fill of remaining triples & quads.
Perhaps I'm nit-picking, but this common tendency drives me batty. It is like we are reinventing the wheel and disregarding all previous logic, often hard won.
There is no "efficiency" in such indiscriminate use of this computer function, especially when it hampers the path of the solve, as it often does.
Usually Simon finds an alternate, more difficult path... but often that little tic stymies progress completely. If hand done, this pitfall would be rarer, I think.
That said, I thoroughly enjoyed the approach Simon took to breaking in on this fascinating puzzle.
The "error" occurred when pencil marking the triple in box 6, which then impeded logic on boxes 4 & 5. No big deal; he found another way. And finally addressed it when 6 was placed in box 9.
But I could predict from the second he put 3 possibles in a bi-colored cell, the oversight was going to persist for most of the solve.
Agreed, and it's so easily fixed by entering the center marks, paring them down to match the corner marks, then removing the corner marks, rather than deleting everything then entering the n-ple
somehow, I was confusing Renban and german whispers for a few minutes... The rectangles are still interesting!
🎼 There’s blue in the corner! 🎶
Gets 3 in the corner… 🦗
Bummer, I didn’t notice the problem with 2 in box seven. I mean this just proves what I said earlier, Simon is sure to solve it systematically. Color! He taught us how to use color, why don’t I think of it?
Does anyone else delete the colors from the grid as soon as they're no longer useful? I feel like they are a hinderance once pencil marks are in.
Did he just say "nether regions"??? 😆😆
Darn, it took me 1:16:20, and I still needed several hints. Probably because I kept misreading the puzzle as symmetrical where it wasn't.
Came back to it a second time, and got it in 38:23, almost half the time!
41:36 for me. coloring masterpiece
