Thanks for featuring my puzzle! Beautiful solve by Simon, opened live on camera, *and* we got to hear him on classical guitar? It doesn't get much better.
I missed something, because I had to guess in the endgame. Was there some way to find the sum of the cage near the bottom of column 5? (A little later watching the video.) Okay, I think I get what happened. The bottom cage was part of the 70 cage, and that cage formed a cross in block 5. At least that adds up right. Then the horizontal cage in row 6 is unspecified, but Sudoko took care of that.
Simon refusing to fill in the ninth digit in a row or column, and completely ignoring previous pencil marks are the small things that mean I do not feel completely outclassed, despite obviously being outclassed.
Yes, he is usually very good at complex things and misses simple stuff. Some of the puzzle he solved we could not crack at all, but we stopped the video AFTER he "cracked the cryptic", and it took us less time to finish it! No joke. (of course, he is wasting a lot of time with explanation, so that is not a fair comparison, but we commented in the past that we can make a good team, he cracks them and we finish them 😆). Especially at cleaning the pencil marks, he is so stubborn 😀, that we think he does it intentionally to provoke comments like these😛.
Technically there's no distance you can get from a black hole where it doesn't attract you, the way gravity works is that everything in the universe attracts everything else in the universe at least a little bit. The event horizon is just the distance from the singularity where even photons no longer have enough momentum to escape being pulled in. Although it was previously believed that nothing could get out of a black hole, we do know that at least they emit Hawking radiation.
Thanks for this! Correct me if I'm wrong, but I think information cannot escape the black hole, even via Hawking radiation (which is uniform)? Or put another way, there is no internal structure to it, it's just a point in space with a particular mass.
Gravity density provides a downhill direction. An easiest way to go and a hardest direction too. Inside the event horizon the hard way to go is so steep nothing can go fast enough to go further uphill. Downhill at any location is all density of mass in the universe weighted by (divided by square of) distance. The higher that density the slower time passes at that point. Physical processes are slowed. The observable universe expands in the time direction from each point.
If you want to get technical about it, a black hole doesn't pull on anything, it just warps spacetime so much that there literally isn't a path out of it past the event horizon.
Technically yes, but the gravitational attraction equation tells us that force drops off by r^2. This doesn't count the fact that G, the gravitational constant, is something like 10^-11. If we want to exert 1N of force at 1m away, we have to have a mass of 100000000000kg. If we move 10m away, the force is now .01N. Gravity is an incredibly weak force compared to all others that we know of.
Clever puzzle, great solve! I also really appreciate being able to witness Simon's growing confidence over time in these lovely guitar intros/outros. This song is a long-time favorite and I really enjoyed this rendition. 💖
Lovely puzzle to solve, although I got totally stuck midway and had to come back to Simon's solve to learn that the renban was for VALUES not digits, and then back to complete the solve. Really nice.
These are the ones I love to just sit back and watch! My brain cannot comprehend how anyone could solve this let alone SET this!! Absolutely incredible Simon and bravo to @thejuggler42 for such a unique setting. Not to mention as a space nerd I love this
Beautiful sudoku, guitar and solve. I loved your reaction to the renban line as it revealed its secrets, Simon. Thanks so much for the fun this evening!
The event horizon is the point where light can't escape. It doesn't really get pulled. It's more like a being inside a giant bowl. The gravity of the black hole causes space and time to curve. So if you're inside the event horizon and try to walk out, you'll just keep walking around and around the inside edge of the bowl, since it's all a giant curve. Trying to walk out just makes you circle around.
I'm not a science expert by I guess another way of formulating it could be to say that event horizon is the borderline at which the energy required to get an object escape the vicinity of the black hole becomes infinite. I might be wrong but it's a guess.
ALL gravity is a curvature of spacetime. Black holes aren't really that special, the only difference between a black hole and our planet is that a black hole has a LOT more mass, and thus a LOT more gravity. To me it feels a bit misleading to say that you can't escape because "spacetime is warped to the point that you can only walk in circles". Yes that is trivially true, but it comes across as much more "mystical" than it really is. Gravity on earth works the exact same way. When you throw a ball straight up into the sky, all possible paths for that ball lead back towards the earth simply because your arm isn't capable of throwing it at escape velocity. We can get nitty gritty and say "the ball is travelling in a straight path the entire time, but the mass of earth is curving spacetime around itself which makes the ball appear to travel in a parabola and fall back towards the planet", but this is just a more technical way to describe how "gravity pulls the ball down". Trying to escape a black hole is exactly like throwing a ball up into the sky. It is impossible to throw the ball hard enough to gain any upward momentum, so therefore all possible paths will arc down towards the black hole. Things do get a touch weird since ALL upward movement is impossible, so the height from the throw would be clamped to zero and there would be no "lob" to the trajectory (hence why all movement becomes cardinal "around the edges of the bowl" as you say). Also, as you approach the event horizon, the exact angle of the "Up" direction becomes infinitely precise, but it does still exist. If you were to point your spaceship exactly in that direction and fly at the speed of light, you would simply freeze in place rather than travel around the edge.
Love the guitar intro, though it is very sad, particularly since Simon and Garfunkel are not “old friends” after all these years. 😔. The puzzle was amazing! I couldn’t have figured it out myself, but enjoyed watching our Simon solve it! It’s a lovely day in metro Atlanta today after a very rainy day yesterday. Such is spring in north Georgia. Guy, if you have some of Abagail ‘s cake left, let me know - I can be there within the hour 😉. Looking forward to livestream on Tuesday!
Brilliant! That black hole is "annoyingly smart" for all it is: intricate effects on cage/renban, hiding those constraints... and a bit of a challenge to color the cells when trying to solve it :) Thank you @thejuggler42 very for bringing such a wondeful puzzle to the world, and thank you Simon for featuring it (so I don't have to go hunting for those puzzles and you make pretty good "solving company" as well)
This was remarkable. I started with the positive diagonal. The smallest that can go in the hole has a value of 12. The smallest that can go in the 20 cage in box 7 is 11, leaving 7, which means there must be 123 on the diagonal in boxes 3 and 5, 1 in R7C3, 9 in R8C2. Now the 10 cage in box 3 can only have 45 off the diagonal, with 1 in R2C8. I also liked that doubled 5. In fact, it had to be 5, because anything higher would have required a cell with a value of 11, and that's impossible. It would have been nicer if you'd drawn the cage boundary rather than lines through the centre; that would have kept the renban visually separate from the cage.
Wow, what a special birthday gift to get a shout out from Simon! One small correction, it is Terra who is the very best. Terra, I love and miss you dearly. ❤-C.
That was easier than I expected. At first I was confused by the cages and renban lines coming out of the black hole. But when I started with the easier clues and had more information, it became clear how to approach the clues in the middle. What a brilliant puzzle.
I finished in 58 minutes. This was such a cool puzzle to do with a fantastic pathway. The break-in involving minimums on the big positive 30 little killer was incredible. I think my favorite part was realizing that r6c5 had to be a 5 and fix the renbans to each other. I had to reread the rules and caught that killer cages specifies digits instead of values, which was wonderful in the moment as I thought I had broken it. This was a very enjoyable sudoku. Great Puzzle!
What a great puzzle - for me that cell Simon talks about most (no spoiler) is my favorite piece of logic and favorite cell of 2024 so far! Just brilliant!
Amazing puzzle. I stumbled (or rather bumbled) into the "brilliant cell" deduction via an error: when I was working out the negative diagonal, I forgot I could repeat digits in the lower right. So I had a (wrong) 123 down there, which forced 45 into the black hole, which put a 6 into the key cell, which had me scratching my head how to put a value of 12 on a renban. This eventually kicked my brain onto the right track.
I'm proud of myself for working out early in my solve that the 70 cage had to include exactly 5 digits in the black hole which add up to 25, which paid off about where Simon got stuck for a moment
I like how the Renban line is carefully constructed in such a way that both ends see both the 5 and the 9, forcing those to be 3 and 7 (at 33:54 in the video)
45:49, I don't get why people say black holes are complicated, I was able to figure this one out in less than an hour. (not getting ANY info in the center except for being able to draw lines is surprisingly hard. I wanted to use colors!)
I absolutely love how Simon says at 35:56 "I can do sudoku on that" speaking of r6c2 and only removes the 5 when it has a 3 and a 9 above in box 1 staring straight at it. Awesome!😄
35m11s. Well that was cool. Working out what was going on behind the event horizon was a really interesting twist on normal hidden information puzzles. It would've been nice if shading on cells behind the dot showed up, but even without that I was able to keep things mostly straight
That was a brilliant puzzle. So confusing and yet every step was so logical. I loved it. Took me just less than an hour, which shows how confused i got! 😂
Test solved this a while ago, and while I got stuck a bit with the 70 cage's actual layout, did finally figure it out and finished it in 44:25 (confict checker off). Very cool puzzle from Michael / Juggler, many props to him!
What a crazy puzzle. I gave up because the big black dot was driving me crazy. I prefered watching Simon and kept playing and trying a little bit in between.
The puzzle was pretty fun to solve, and the black hole gave me a good laugh. I did mess up and have to backtrack into a completely different chain of logic (I also forgot the line was a renban for a while), but the logic flowed pretty nicely. I got a bit stumped here and there, but overall, each step was pretty fair without needing to spot anything insane like the video length might suggest.
@46:58 it did occur to me that Simon could simply wait around for Hawking Radiation to evaporate the black hole....but that would have made for a very long video. The length of that video is left for the reader to determine. Pleases show all working.
Haven’t see the video yet but have an alarm bell about that 70 box. Assuming it spans from R2C5-R8C5, there are three “doubled cells” (say 7-8-9 = 24 x 2 = 48). We need to make an additional 22 points in the remaining four cells…. But we can’t…
I don't know if it'll help at all, but it's called "Last Call BBS" because its the last game made by the developer before retiring. It's a swan song of sorts featuring ideas he couldn't turn into full length games.
This one was too much for me to contemplate, just not being able to click on it made me go a little wonky. Good one to just sit back and watch Simon solve it for me1
Blunders I made during my 4 hours on this puzzle (I had to start over twice sadly): - assumed the renban line had to be in order, which leads to having 2 seperate lines of length 4 and 3... - forgot to double the value of the digit in the 20-cage that touches the black hole oh well
I actually tried to make it that shape! But the puzzle didn't like it. But what's worse is that my visual effect of the grid lines "warping" is in the wrong direction, they should be bending outwards. I have no excuses for that one :P
Bit of a fun fact, if you hack out the black hole, you can see that it's not simply overlaid on the puzzle. The 70 cage extends only as far as you can see and the cage at the bottom is a separate 2-cell cage. The renban lines only go to where they're obscured.
Brilliant puzzle; I have no idea how people come up with these unique constructions. Allow me a small nit-pick. I seem to recall a rule stating that a killer cage's total needs at the top of the left-most cage. Given the final shape of the "70" is a cross, then said cage would be in the black hole and become invisible. Happy that the constructor chose to ignore the restriction. Happier still if I'm barking up the wrong tree!
It is not "top of the left-most cell" but actually "top left-most cell". Meaning it has to be in the top row as left as it can be. So all is good in this puzzle
The event horizon is the point where it's no longer possible for anything to escape the Black Hole - including information. People think of it as 'where the black hole starts', which... eh. Anyways, I sort of love how they represented it - you can't see inside the black hole, so you have to guess what's inside by modeling.
I'm going to immediately say that I do not like the effects of this grid. I don't like not seeing or easily interacting with a section of the grid that has cages and lines going through it. And I especially don't like it when I can't check my answer because something is keeping me from finishing the grid, namely it being impossible to see that a cell is selected in the darkest parts of the black hole. Fog is different in this regard, as you can actually detect selected cells.
I did not try to solve this (way above my pay grade) but I felt the same, really, about the inpenetratableness of the black hole section. I felt that one could never be sure - but then as I thought about it, I felt that *I* could never have been sure, but Simon worked through it logically (and had the help of some clever use of the line drawing tool) and in the end I would say it is clear how things work in there.
@@emilywilliams3237 I didn't doubt it was solvable. My big problem was that it didn't seem especially easy to annotate the grid, especially as the highlighting which indicates you have selected a square is not able to be seen when you select a square entirely inside the black hole. This left me with the feeling I couldn't place a digit in those 5 squares, and I believe I attempted to do so, leaving me with the feeling I had to remember which digit went where within the black hole without any notation. When I saw Simon draw lines upon the black hole, this reduced the puzzle to merely frustrating. I went through this whole puzzle without placing any digits in r456c5 or r5c456, even though there were cells I knew the value of because I was left with the impression I could not notate these squares, and when I didn't receive the completion text, I was rather confused. If it was made where people could see their highlighting even, it wouldn't have left me with such a bitter taste, especially as it would have made it more clear that notation wasn't being forbidden.
@@emilywilliams3237 I didn't doubt it could be completed but the lack of evident highlighting in the blackness of the hole, and I believe I did try notation within it left a bitter taste in my mouth. I don't like puzzles that insist on memorizing and block notating.
The event horizon is the proverbial point of no return, but notably this applies to light. No technology known to man could get remotely close to an event horizon.
I solved the puzzle correctly only to realize that the cage in box 5/6, with an unknown value, had played no part in my solve. Obviously I have made some assumption or logical misstep, but can't see what. Where in the video can I find the purpose of this cage?
Oh good grief. I missed the use of the word 'value' and assumed the renban lines would just use the figures, which renders the puzzle, as far as I can tell, completely impossible to solve. I must have spent a couple of hours looking at it on and off. When I returned to the puzzle after learning how it actually works from the video, (and probably also because Id been staring at all the possibilities for so long.) I finished the rest in about 10 minutes.
Right around 19:59 in the solve this starts to look like the weirdest game of noughts and crosses (that's tic-tac-toe if you're American) in the history of humankind.
I was curious to see if there was anything under the black hole. So I used the f12 menu. Nope! Nothing there. The cages don't extend and the renbans are cut off. lol
Finished in 25:58. I made an assumption that was bad, but which eventually I would have had to make to disprove one part of the cage couldn't be the correct part of another cage. So, I guess in the end, it was good I made that bad assumption? Fun puzzle!
My interpretation: It's saying it doesn't know whether they're part of the 70 cage. The cage in box 8 is part of the 70 cage, in the solution, but the software (rightly) doesn't give that away if you double-click it at the start. That would be a spoiler.
@@RichSmith77I well I worded the entrance as spoiler free, as I could. these cages could as well be a hint, that particular squares can not be part of the 70 cage. Perhaps a clarification in the rules would be at order.
Thanks for featuring my puzzle! Beautiful solve by Simon, opened live on camera, *and* we got to hear him on classical guitar? It doesn't get much better.
That was a wonderfully unique puzzle. I loved it!
Wholeheartedly agree! What a puzzle!!!
absolutely genius puzzle, especially the renban. Thoroughly deserving of the feature
I missed something, because I had to guess in the endgame. Was there some way to find the sum of the cage near the bottom of column 5?
(A little later watching the video.) Okay, I think I get what happened. The bottom cage was part of the 70 cage, and that cage formed a cross in block 5. At least that adds up right. Then the horizontal cage in row 6 is unspecified, but Sudoko took care of that.
What a great puzzle! Thank you!
That "Value" Renban line constraint was absolutely diabolically brilliant and blew my mind lol 😂
One of those puzzles that takes your breath away. Mr. Lefkowitz is a creative genius.
I love how the 1 in the centre sneakily represents the "singularity"
I'm always happy when people spot the subtle easter eggs like this.
@@thejuggler42 is 'c' 30?
h_ is 45
The other Easter egg is that the puzzle has a black dot that means "2:1 ratio", which is actually rather common in variant sudokus.
@@thejuggler42 Mother of all kropki dots 😆
Simon refusing to fill in the ninth digit in a row or column, and completely ignoring previous pencil marks are the small things that mean I do not feel completely outclassed, despite obviously being outclassed.
The way he ignores those poor '2' corner pencil marks in box 6, at 52:05...
lol. He only uses half his pencil marks on average I reckon.
Yes, he is usually very good at complex things and misses simple stuff. Some of the puzzle he solved we could not crack at all, but we stopped the video AFTER he "cracked the cryptic", and it took us less time to finish it! No joke.

It would have been nicer if you'd drawn the cage boundary rather than lines through the centre; that would have kept the renban visually separate from the cage.
Wow, what a special birthday gift to get a shout out from Simon! One small correction, it is Terra who is the very best. Terra, I love and miss you dearly. ❤-C.
1:34:47 - Gorgeous puzzle. I think my favourite bit of logic was the renban line.
Yes, that was clever setting, and a good joke too.
Superb puzzle and great solve Simon.
Such a beautiful melody!
That was easier than I expected. At first I was confused by the cages and renban lines coming out of the black hole. But when I started with the easier clues and had more information, it became clear how to approach the clues in the middle. What a brilliant puzzle.
I finished in 58 minutes. This was such a cool puzzle to do with a fantastic pathway. The break-in involving minimums on the big positive 30 little killer was incredible. I think my favorite part was realizing that r6c5 had to be a 5 and fix the renbans to each other. I had to reread the rules and caught that killer cages specifies digits instead of values, which was wonderful in the moment as I thought I had broken it. This was a very enjoyable sudoku. Great Puzzle!
What a great puzzle - for me that cell Simon talks about most (no spoiler) is my favorite piece of logic and favorite cell of 2024 so far! Just brilliant!
Wow, looked a bit hard based on the video length, but managed to wangle it out by myself, very satisfying!
Finished in 78:34. I almost gave up on it but I'm glad I didn't. Figuring out the renban lines was a very cool deduction.
Oh amazing sudoku puzzle and great the music intro!!!
All the best from a musician amd guitarist from Hellas Greece 😊😊😊🇬🇷🇬🇷🇬🇷🎶🎶🎶
We had both Simon and Garfunkel 😊Another great video!!
Amazing puzzle. I stumbled (or rather bumbled) into the "brilliant cell" deduction via an error: when I was working out the negative diagonal, I forgot I could repeat digits in the lower right. So I had a (wrong) 123 down there, which forced 45 into the black hole, which put a 6 into the key cell, which had me scratching my head how to put a value of 12 on a renban. This eventually kicked my brain onto the right track.
I'm proud of myself for working out early in my solve that the 70 cage had to include exactly 5 digits in the black hole which add up to 25, which paid off about where Simon got stuck for a moment
I like how the Renban line is carefully constructed in such a way that both ends see both the 5 and the 9, forcing those to be 3 and 7 (at 33:54 in the video)
45:49, I don't get why people say black holes are complicated, I was able to figure this one out in less than an hour.
(not getting ANY info in the center except for being able to draw lines is surprisingly hard. I wanted to use colors!)
I absolutely love how Simon says at 35:56 "I can do sudoku on that" speaking of r6c2 and only removes the 5 when it has a 3 and a 9 above in box 1 staring straight at it. Awesome!😄
And then a few moments later removes the 9 because there’s a nine above it… but not the three above that :)
“And, of course, if you’re watching this video you’re one of my Old Friends”
30:14
Drawing information from inside the event horizon of a black hole! Incredible trick.
At the 20-minute mark Simon missed the 10 cage in box 3. That place a 1 and give you a 4,5 pair.
35m11s. Well that was cool. Working out what was going on behind the event horizon was a really interesting twist on normal hidden information puzzles. It would've been nice if shading on cells behind the dot showed up, but even without that I was able to keep things mostly straight
That was a brilliant puzzle. So confusing and yet every step was so logical. I loved it. Took me just less than an hour, which shows how confused i got! 😂
Test solved this a while ago, and while I got stuck a bit with the 70 cage's actual layout, did finally figure it out and finished it in 44:25 (confict checker off). Very cool puzzle from Michael / Juggler, many props to him!
Loved the puzzle AND the excellent guitar!
What a crazy puzzle. I gave up because the big black dot was driving me crazy. I prefered watching Simon and kept playing and trying a little bit in between.
The puzzle was pretty fun to solve, and the black hole gave me a good laugh. I did mess up and have to backtrack into a completely different chain of logic (I also forgot the line was a renban for a while), but the logic flowed pretty nicely. I got a bit stumped here and there, but overall, each step was pretty fair without needing to spot anything insane like the video length might suggest.
@46:58 it did occur to me that Simon could simply wait around for Hawking Radiation to evaporate the black hole....but that would have made for a very long video.
The length of that video is left for the reader to determine. Pleases show all working.
Brilliant but weird! I almost couldn't believe I was actually solving it.
Simon: the event horizon is the 'line' from which not even light can escape. It's the literal "black hole".
Oh yes a guitar intro, perfect to set the mood
Haven’t see the video yet but have an alarm bell about that 70 box. Assuming it spans from R2C5-R8C5, there are three “doubled cells” (say 7-8-9 = 24 x 2 = 48). We need to make an additional 22 points in the remaining four cells…. But we can’t…
15:38 for me. Very weird idea, but I enjoyed the puzzle a lot!
I don't know if it'll help at all, but it's called "Last Call BBS" because its the last game made by the developer before retiring. It's a swan song of sorts featuring ideas he couldn't turn into full length games.
"we are streaming NO THAT'S THE CHOCOLATE CAKE!"
but I would watch a cake stream
This one was too much for me to contemplate, just not being able to click on it made me go a little wonky. Good one to just sit back and watch Simon solve it for me1
Stared for 45 minutes and couldn’t break in so I gave up and came back to watch the solve
Blunders I made during my 4 hours on this puzzle (I had to start over twice sadly):
- assumed the renban line had to be in order, which leads to having 2 seperate lines of length 4 and 3...
- forgot to double the value of the digit in the 20-cage that touches the black hole
oh well
Ooh, can't wait to see this, it's very interesting - sort of like non-clearing fog.
Always love a guitar intro, so that was an extra treat today 😊
I love it when Simon plays the music in the intro! Infinitely better than the corrupted Mozart Sonata.
Technically, the outflow jets from the black hole (the renban line) should've been rotationally symmetric, not reflection symmetric
I actually tried to make it that shape! But the puzzle didn't like it. But what's worse is that my visual effect of the grid lines "warping" is in the wrong direction, they should be bending outwards. I have no excuses for that one :P
Managed it in 34:51 after some deliberation over the break-in.
Bit of a fun fact, if you hack out the black hole, you can see that it's not simply overlaid on the puzzle. The 70 cage extends only as far as you can see and the cage at the bottom is a separate 2-cell cage. The renban lines only go to where they're obscured.
Oh man, you caught me. I had to do it this way so that SudokuPad wouldn't spoil the puzzle when you double click on the cage to highlight it :)
Brilliant puzzle; I have no idea how people come up with these unique constructions. Allow me a small nit-pick. I seem to recall a rule stating that a killer cage's total needs at the top of the left-most cage. Given the final shape of the "70" is a cross, then said cage would be in the black hole and become invisible. Happy that the constructor chose to ignore the restriction. Happier still if I'm barking up the wrong tree!
It is not "top of the left-most cell" but actually "top left-most cell". Meaning it has to be in the top row as left as it can be. So all is good in this puzzle
@6:48 inb4 Simon & Mark stream chocolate cake next Monday
Can’t wait for that! But how will they make it last 2 hours?
The event horizon is the point where it's no longer possible for anything to escape the Black Hole - including information. People think of it as 'where the black hole starts', which... eh. Anyways, I sort of love how they represented it - you can't see inside the black hole, so you have to guess what's inside by modeling.
You're the first person who's fully understood the title of the puzzle :)
20:52 "I was drawn to it"
Maybe intentional pun
Quite an intimidating puzzle but it wasn't too bad, as it only took me 33 minutes to solve.
I'm going to immediately say that I do not like the effects of this grid. I don't like not seeing or easily interacting with a section of the grid that has cages and lines going through it. And I especially don't like it when I can't check my answer because something is keeping me from finishing the grid, namely it being impossible to see that a cell is selected in the darkest parts of the black hole.
Fog is different in this regard, as you can actually detect selected cells.
I did not try to solve this (way above my pay grade) but I felt the same, really, about the inpenetratableness of the black hole section. I felt that one could never be sure - but then as I thought about it, I felt that *I* could never have been sure, but Simon worked through it logically (and had the help of some clever use of the line drawing tool) and in the end I would say it is clear how things work in there.
@@emilywilliams3237 I didn't doubt it was solvable. My big problem was that it didn't seem especially easy to annotate the grid, especially as the highlighting which indicates you have selected a square is not able to be seen when you select a square entirely inside the black hole. This left me with the feeling I couldn't place a digit in those 5 squares, and I believe I attempted to do so, leaving me with the feeling I had to remember which digit went where within the black hole without any notation. When I saw Simon draw lines upon the black hole, this reduced the puzzle to merely frustrating. I went through this whole puzzle without placing any digits in r456c5 or r5c456, even though there were cells I knew the value of because I was left with the impression I could not notate these squares, and when I didn't receive the completion text, I was rather confused.
If it was made where people could see their highlighting even, it wouldn't have left me with such a bitter taste, especially as it would have made it more clear that notation wasn't being forbidden.
@@emilywilliams3237 I didn't doubt it could be completed but the lack of evident highlighting in the blackness of the hole, and I believe I did try notation within it left a bitter taste in my mouth. I don't like puzzles that insist on memorizing and block notating.
Epic puzzle ❤
The event horizon is the proverbial point of no return, but notably this applies to light. No technology known to man could get remotely close to an event horizon.
Not that hard after you solve it 😅
Quite charming puzzle for today! 😊
I just watched The Looker video. 14:03 reminds me of the ending lol
Event horizon is the point where everything starts turning into spaghetti. This is the formal definition, I'm sure.
I solved the puzzle correctly only to realize that the cage in box 5/6, with an unknown value, had played no part in my solve. Obviously I have made some assumption or logical misstep, but can't see what. Where in the video can I find the purpose of this cage?
Oh good grief. I missed the use of the word 'value' and assumed the renban lines would just use the figures, which renders the puzzle, as far as I can tell, completely impossible to solve.
I must have spent a couple of hours looking at it on and off. When I returned to the puzzle after learning how it actually works from the video, (and probably also because Id been staring at all the possibilities for so long.) I finished the rest in about 10 minutes.
Cool one, solved in 25:59
35:59 for me - it's like Kurzgesagt made a Sudoku puzzle.
I wonder if the black hole would disappear due to Hawking radiation, if you waited long enough :-D
41:26 for me
nice puzzle
Right around 19:59 in the solve this starts to look like the weirdest game of noughts and crosses (that's tic-tac-toe if you're American) in the history of humankind.
I was curious to see if there was anything under the black hole. So I used the f12 menu. Nope! Nothing there. The cages don't extend and the renbans are cut off. lol
Never look directly into a black hole.
If anyone could divulge a solution to Collatz conjecture it'd probably be Simon.
Can't Highlight the cells in the black hole cause light can't escape the black hole
Why does Simon ignore the pencilmarked 2's when he fills out box 6?
What happened to my comment about Dr Becky and PBS Spacetime talking about black holes?
33:04 for me
Finished in 25:58. I made an assumption that was bad, but which eventually I would have had to make to disprove one part of the cage couldn't be the correct part of another cage. So, I guess in the end, it was good I made that bad assumption?
Fun puzzle!
Never klick on a Black Hole!
4:50 what was that word? Sounds very vulgar but knowing this channel i must be mishearing it
So tuesday live stream of eating chocolate cake?
I’d watch that!!😃
First time I have noticed the fake eyelash - Sven must be bored!
Not Black Hole Sun?
21:45 for me. it was not very hard. i like killer sudoku.
65:39. I didn't enjoy it but l stubbornly chipped away.
Not sure if I logically placed the renban, but it all panned out alright in the end...
I love the fact that the rules didn't mention anything about cages not being able to overlap, yet they actually don't.
EXILE
here is my problem with this Puzzle:
The cage parts in box 8 and 6 do not belong to the 70 cage wich you can see if you doubleklick them.
Not even Sven's software can see what's inside a black hole.
@@thejuggler42 well but it tells you it can.^^ it says those are different cages.
My interpretation: It's saying it doesn't know whether they're part of the 70 cage.
The cage in box 8 is part of the 70 cage, in the solution, but the software (rightly) doesn't give that away if you double-click it at the start. That would be a spoiler.
@@RichSmith77I well I worded the entrance as spoiler free, as I could. these cages could as well be a hint, that particular squares can not be part of the 70 cage.
Perhaps a clarification in the rules would be at order.
I don't like how the giant dot blocks the puzzle area.
