ZegreS here! Very rewarding to see this featured since this puzzle took me VERY long to set. Also this is 4/5 difficulty - just so people set their expectations right. Thanks so much for solving and for the Ren shout out! I did come up with Marble Run (just got my book delivered and may hang that page on the wall) The sharp eyed will notice that this is just marble run in disguise ... in space. The success message (which had it's line breaks erased somehow) is a reference to the Beastie Boys song Intergalactic. I was originally going to only count cells on the galaxy towards cage sums, but this worked better. I would be VERY HONORED if Simon did a bit of Bestie Boys on his guitar some time in the future... (Sabotage?) Although I am honored already by this great feature!

Skipped due to unclear rules. The interpretations "In cages, digits not part of the galaxy sum to the given total." and "In cages not part of the galaxy, digits sum to the given total." both seem reasonable from the wording given. I didn't really want to guess which interpretation is correct, or to try one until it proves to be unsolvable, and then use the other.

@chris5619 5 месяцев назад

51:10 The more elegant way is to do math on column 5. If the 17 and 7 cages are both fully green then the 8 green cells in that column add up to 5+6+7+17=35 and that would require the singular cell in the middle to be a 10 which is impossible.

@listey 5 месяцев назад

My way into it (admittedly only as a spectator to this video) was to note that if either 16 cage contained a red cell then the two green cells would need to be 7+9. Then using the rotational symmetry the other 16 cage would need to be 7+9 plus a red cell. And then there's no room for both the 7 and the 9 in box 5, using our old friend Sudoku!

@CauchyIntegralFormula 5 месяцев назад

56m57s. I love the logic of this! I had to use assumption for the sake of contradiction in a few spots, which makes me miss the "trial mode" of PUZ-PRE: the ability to say "let me mark this spot in my logic and then proceed along an assumption that I believe to be false; then, when I run into a contradiction, I can revert back to that spot and deduce that the assumption is false". It let me conclude, for instance, that only one cell among the eight used in cages in box 8 was part of the galaxy. Currently, I simulate this by shading the cell with my assumption gray just before proceeding along the logic, then using the back button liberally to just before I placed the gray shading to revert

@chipsounder4633 5 месяцев назад

The two 16 cell cages in box 2 and box 8 couldn't be 2 cell sum. Via rotational symmetry it would have made the centre digit a Schrödinger cell😁 beautiful

@SarlCagan93 5 месяцев назад

Wonderful puzzle and video! Unless I'm missing something, I believe as early as 30:00, once Simon deduced the central columns needs a galactic cell, knowing the 17/16 cells in box 8 need 5 non-galactic cells tells you the 16 cage has to be all non-galactic (which opens up a lot more logic)

@zegres 5 месяцев назад

There were a few areas where Simon was not perfectly efficient - there did seem to be a lot of distractions, but I am happy since I made it over an hour for the first time! The intended path was to do boxes 2 and 8 after the middle box, but the way Simon did it is completely legit and just a parallel solve path that is a bit harder. It would have helped him a lot more to think of the 16, 17 and 16, 7 cages separately and not as a block, but he got that idea into his head and it seemed hard to detach from it. There is a lesson there.

@femto113 5 месяцев назад

It feels like there is a potential short circuit in this puzzle: one can infer that any blank cells bordering a galaxy cell must be part of the galaxy because if they weren't they'd be ambiguous and the puzzle would be unsolvable. If we assume that solvability is not meant as a direct clue then this implies the shape of the blank areas is necessitated by the location of in-cage galaxy cells, from which we can infer many of their locations, particularly in boxes 1, 3, 7, and 9.

@JamesRisse1 5 месяцев назад

I don't know if it's been pointed out already as I haven't taken the time to real all the comments, but you mentioned that there must be a more elegant way to prove where the galaxy goes in boxes 2 and 8. If you look at the sum of column 5 it's easy to see it needs more galaxy squares than just the central digit. Great job I needed your help 3 times to solve this puzzle which hasn't happened on a three star puzzle in a while. (I think it deserves an extra difficulty star.)

@kevinmartin7760 5 месяцев назад

Around 33:00 all you have to do is consider the six white cells in column 5. Because 5 and 6 are not available, their minimum total is 25 (1+2+3+4+7+8) which exceeds the cage totals. Thus there must be red cells in these places, and so you can conclude that column 4 in box 2 and column 6 in box 8 are all green (since you only have one red cell to allocate to each of the two 2x3 rectangles). Simon went through the board looking at boxes that contained cages with impossible combined totals but did not really look for the same effect in rows and columns. In this particular case, there is no conclusion to be reached until the 5 and 6 have been placed in box 5.

@maljamin 5 месяцев назад

Surely it's been noted by now but you can sort out boxes 2 and 8 easier (and earlier). Just ask what if the 7-cage in c5 was all non-galaxy. Then (assuming 5 and 6 are placed in box5) there is no way to also have a non-galaxy 17 cage, with 12456 used up. So those cages have 1 galaxy cell each. Which was forcing a lot of non-galacticity and that pretty much resolves those boxes. Alternately but similarly just use the secret and ask what the central digit must be if the 17- and 7-cages were galaxy-free.

@craigfjay 5 месяцев назад

29:45 if the 7 and 17 cages in column 4 were all green, then you can use the secret. 7 + 17 + 5 + 6 in box 5 leaves the centre cell being a 10. That means the red cell must be in the 7 and 17 cages, so the 7 cage is a 3/4, the 17 is 8/9, and the 16 cages are both green

@slovakio223 5 месяцев назад

Please I’d love to see simon solve Broken Secrets, it is such an interesting puzzle!!

@57thorns 5 месяцев назад

At 51:08 I think the secret would be useful. But it is all about what you happen to see. Down column five we have 7+17+5+6+r5c5 = 45 is there is not galaxy in the column. But that would make r5c5 10 so there is a galaxy in the cages in column 5. Meaning we can greanify all of the 16 cages.-

@Mister_Bates 5 месяцев назад

@moersertrupp 5 месяцев назад

Still watching the video, so dont know if he finds it later, but what i found beautiful is in column 5, if the 7 and 17 cage would both be green, that wouldnt work, as the 7 cage would be 124 and the lowest the 17 cage could contain is 378, which sums to 18

@joemucchiello4542 5 месяцев назад

@1.03.54 a simple way to say R9C1 is green is to say, since only one of the 14 cage cells is red, you can't reach the corner cell unless it is not orthogonally connected to the rest of the galaxy.

@lunardancer6047 5 месяцев назад

With uniqueness, I always assume that only applies to the numbers in the grid itself and not the colouring. So in this puzzle, I made all the uncaged digits in the corner boxes red as I knew they either were definitely were red to connect the galaxy or they could be either as they don't affect cage totals and there's no requirement for green to orthogonally connect.

1:00:00 finish. I started off by considering if the galaxy could travel vertically from the center cell. If it did, it would place a 5 in r4c6 and a 6 in r6c4. This would break the puzzle, because the 6 cage in box 2 could not be two cells (sees both 4 and 5 in the column), and the 6 cage in box 8 could not be one cell (sees a 6 in the column). This places the 5 and 6 in column 5 of the center box, and the galaxy extends horizontally from the center. I then added the totals in column 5, and if nothing was galaxy, then the center cell would have to be a 10. Therefore, the 7 and 17 cages need to be two cells each. I flew through things from there, until I got to boxes 3 & 7, getting stalled for quite a while about the 7-8 pair in box 4. When I was down to just the corner cages, I was able to establish that the 3 cage in box 1 couldn't be a 1-2 pair. It would place an 8 as the only counting cell in the 8 cage, and an 8 in r6c1. It places the 2 in column 3 of box 4, and then a 2 in the 14 cage of box 7. If the 14 cage used the 2, it would be three cells, and the 8 would be a single cell cage (from the mirror restrictions) and broken (sees 8 in the column). If the 14 cage didn't use the 2, it would be two cells, a 5-9 pair. This would mean that the 8 cage couldn't be a single cell (sees 8 in the column), or two cells (sees 1-2 in the column and 5 in the box). Therefore, the 3 cage is a single cell 3. (This was the point at which I stalled out as I previously stated, with this being the last piece of logic until I broke through my block).

The rules as written (and described in the video) allow for any number of degenerate solutions, taking the entire grid as a single square galaxy and breaking each cage. What in the rules is supposed to prevent this? EDIT: I think I have it. Digits in cages (excluding digits in the galaxy) add up to the totals in the cage. I read it as "ignore cages that are part of the galaxy".

i understood it like you, its poorly worded for sure^^

@bobbie0976 5 месяцев назад

At first I thought the same, yr edit made me understand the rules

@scruffamudda6306 5 месяцев назад

I couldn't figure this out either. There needs to be a rule about not breaking cages to make it solvable.

@BryanLu0 5 месяцев назад

The cage in the middle sums to zero, so this should clear any confusion.

At 40:00, why couldn't the 8 cage in Box 4 have a 134 within it that was green? I don't think Simon ruled that out.

@David_K_Booth 5 месяцев назад

At 23'55" I was kinda hoping for the chair to have a series of speech balloons along the lines of "Hi! I'm Simon's chair. Nice to meet you." "How are you doing?" "Oh wait, he's coming back, catch you later."...

@stevenwojtysiak6392 5 месяцев назад

I believe that is the Beastie Boys, intergalactic.

@srwapo 5 месяцев назад

85:44 with a lot of help. I had to look at how to use the 6 cages in Boxes 2 and 8 to start the puzzle, then kept hitting walls and seeing it was because of dumb mistakes. NUMEROUS times it was because I typed in a digit for the cage total in the galaxy (instead of the vacuum of space between galaxies in this analogy...).

@LednacekZ 5 месяцев назад

the column4 cages cant be full 3cell cages because they add up to 24 and with the 11 in box5, the middle r5c5 square would have to be 10.

@Rach881101 5 месяцев назад

54:35 for me. Beautiful puzzle!

@BryanLu0 5 месяцев назад

1:12:08 row 3 column 8 is a naked single It can't be 1235 by the column, 46 because the 7 cages need those, and 79 by the row

" why do I start there rather than starting with something simple?" Simon finally heard me shouting. 1:02:10 lol

@alcaz0r1 5 месяцев назад

I'm a bit confused about the rules, what is constraining this to a single solution? Why can't I mark the whole grid as being in the galaxy? At that point there are no cage restrictions and I can fill in the board with any valid sudoku digits.

@alcaz0r1 5 месяцев назад

I think I get it, "digits in cages that are not part of the galaxy sum to the ..." implies that there must be one or more digits in each cage summing to the cage total.

@BryanLu0 5 месяцев назад

The rules are a bit unclear, but the zero cage in the center should clear things up. (As in, the non galaxy cells add up to zero in the cage with no non galaxy cells)

@alcaz0r1 5 месяцев назад

121:37, very rewarding puzzle! I loved figuring out how the galaxy had to grow throughout the solve.

@Orenotter 5 месяцев назад

The instructions are confusing. I read "That are not part of the galaxy" as modifying "cages", not "digits", so I was doing the puzzle wrong for several minutes.

@HunterJE 5 месяцев назад

On a similar note could skip all the maths at 1:03:36, r1c9 can never be red because it has to connect with the rest of the galaxy which would require a 1-cell 14 sum...

@madsli 5 месяцев назад

The easiest way to see that there has to be another red cell in column 5 at around 30:00 is to just count the values. 7+17+5+6=35, even if you put a 9 in the middle cell, it does not add up to 45.

@thebitterfig9903 4 месяца назад

Another way to get to the same end which occurred to me while watching, if column 5 in box 2 is all green, it’s 124, and with 56 placed, you can’t make 17 in the cage in box 8. 3+7+8 is the lowest possible, which is 18.

@mstmar 5 месяцев назад

i saw a beautiful deduction at around 28:00. can the 16 contain any galaxy? if it does, it can only have one cell of it, since you cant make 16 with less than 2 cells. with 1 galaxy cell, it has to contain a 7 and 9. it's counterpart would also be a 16 with a galaxy and so also contain 7 and 9. but then where do you put the 7 and 9 in col 5? both in the same cell. *checks the rules for Schrödinger cells* and so this is broken and so the 16 has to have no galaxy cells.

@koenth2359 5 месяцев назад

The uniqueness argument brings up a question I've had for a long time. If a puzzle's assignment is to find the correct digits, and the pattern (yin/yang, galaxy, pentominos, whatever) is considered not as the goal, but just as a way to accomplish that, would a puzzle be considered valid if it had ambiguous colouring, but a unique way of placing the digits?? (It would not feel as satisfying, I agree at least on that)

@zegres 5 месяцев назад

I think the common understanding of uniqueness requires both to be unique. If I was to make a puzzle with a unique grid but ambiguous coloring, I would explicitly state that in the rules.

@bobblebardsley 5 месяцев назад

The title of this puzzle makes me wonder if anyone has created a galaxy puzzle where the 'edge' constraint (i.e. galaxies cannot extend beyond the edge of the puzzle) does not apply.

@harmonicaveronica 5 месяцев назад

I think the phrasing of the rules could be a bit clearer on this one - I read it to mean that if a CAGE is not part of the galaxy, then the digits inside can sum to anything but that number. Rather than that digits in cages sum to the total in the corner, but cells that are part of the galaxy do not contribute to the cage total

@makerpat 5 месяцев назад

That confused me as well.

@jerseytiger1980 5 месяцев назад

Simon is not a Beastie Boys fan I suppose 🤣. The words at the end are an extract and play on the Intergalactic lyrics.

@RoderickEtheria 5 месяцев назад

No, it's a musical finish. Beastie Boyz to be exact.

@LednacekZ 5 месяцев назад

i misunderstood the rules. there is nothing written about the squares outside of cages. i thought they were apart of the galaxy too.

@zegres 5 месяцев назад

Almost forgot to say, since this is a Beastie Boys themed puzzle and Simon mentioned Ren, I recommend everybody check out “What You Want” by Ren that is his Beastie Boys tribute.

@chucksimmons2724 5 месяцев назад

The first part of this puzzle seems to be finding an interpretation of the rules. I don't see any rule that prevents the entire 9x9 grid from being the galaxy.

@chucksimmons2724 5 месяцев назад

Although the rules can be read as meaning that each cage is either part or not part of the galaxy, presumably we are supposed to decide that each cage must have sufficient non-galactic cells to allow its sum to be satisfied...

@joemucchiello4542 5 месяцев назад

Early in the puzzle, the secret tells us that R7C4 cannot be 6 because then the whole box aside from R7C4 is non-galaxy. And that doesn't work in box 2 where only R3C6 would be galaxy. Was this not obvious? And then you know the two 6 cages contain a 6 and non-galaxy digit. In box 8, the only non-galaxy digits are 15, 24, or 123.

@ajreukgjdi94 5 месяцев назад

14:10 why not? Nowhere in the rules does it say all cage totals must be fulfilled. What if no digits in the 3-cage added up to 3? How would that break the rules? I absolutely would not have made that assumption. Which probably means I wouldn't have been able to break into this one on my own. But I don't try puzzles that take Simon over 40 minutes, so I'll never know.
