** TODAY'S PUZZLE **
We've had multiple requests and recommendations to attempt today's suduoku: Unique Japanese Sum Sudoku from tesseralis. The ruleset is extraordinary and it is barely credible that this can "exist"... the only thing we know is that all the clues have to be different... but we're not told any of them. Strap in for one of the most interesting, difficult and downright brilliant sudokus we've ever seen.
Play the puzzle at the link below:
app.crackingthecryptic.com/su...
Rules:
Normal sudoku rules apply. Digits joined by a white dot are consecutive. Japanese sums: Shade some cells in the grid such that the clues outside the grid indicate the sums of the contiguous runs of shaded cells found in that row or column. Multiple runs in the same row or column must be separated by at least one unshaded cell. Each caged cell represents a unique positive number. A question mark can represent any positive number.

Yay! So happy to see this get featured. It truly is a miracle construction: I made it sleep deprived on a red-eye flight to halifax and was so excited that it didn't break that I spent time at the airport and hotel lobby finishing the rest of it! Fantastic solve that surprised me in a lot of places! You got the way the 2-cell sums were divvied up very quickly and, though it took a while to get there, the way you explained why orange couldn't be 6 is the prettiest explanation I've seen. I'm honored :)

@tedg1278 8 ай бұрын

I was very confused by the ambiguity of the ? clues outside the grid because the rules lacked definition regarding the order in which external clues apply to the grid. Having those clues apply a left->right order is required for the puzzle to solve uniquely, but the wording leaves the order completely undefined and even seems to indicate that it is irrelevant. Simon in his solve uses a left->right ordering numerous times for specific logic.

@flobiish 8 ай бұрын

@@tedg1278 I get this. If one isn't familiar with Japanese sums maybe it isn't blatantly obvious but the staggered order of the ?'s might give pause for thought about the possibility. If there hadn't been any ? clues, the ordering criteria wouldn't even make a difference. Simon definitely used the missing "in that order" criteria when solving. Maybe we could start a petition on one of those petition websites to get this added to the directions on the puzzle in the link (this is just me being facetious)?

@flobiish 8 ай бұрын

I'm not a player or setter, but it seemed to me (as a casual onlooker...maybe an obsessive onlooker as I've watched nearly every video they've released since 2020) that the solve path seemed to use the clues in a very specific order and I wonder if the setting path was basically the same path. I can imagine that finding/inventing this was extremely satisfying, maybe moreso than solving is. The ending was most epic and I can't really see how those numbers could even have been planned.

The weirdest thing about this puzzle is the pattern of sums it uncovered: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 1. There are a maximum of 9 single-digit sums. Once they're all used, 2. There are a maximum of 8 two-digit sums, since 9+8 is the largest. Once they're all used, 3. There are a maximum of 7 three-digit sums, since 9+8+7 is the largest. This pattern continues all the way down to 1 nine-digit sum, as long as you keep using up every possible sum from the previous digit.

I ended up having to come back twice to the video to get a hint (first to realize that the 17 had only place to go, and second to get prompted to do some exhaustive casing down in the bottom right, eventually leading to the realization that only one combination was actually possible). Anyway, uh, 3:47:31.

Pretty proud of myself for making it that far, at the very least. Edit: Ah, lots and lots of math with three pairs, got it. Edit 2: Finished the rest all on my own! I couldn't really figure out what I was supposed to do to figure out which was the 19 and which was the 20, though. Tried one as the 4-6 to see if it broke the puzzle and it ended up resolving, which I know is how resolving digits goes sometimes but it didn't feel like that was supposed to be resolved in that way. Fun puzzle though. I tend to quite enjoy the math ones, I get a pretty big notes section on my phone after puzzles like these :)

1:55:06 finish. I flew through the beginning of this puzzle, finally getting stuck with the two-cell cages on the right side of the grid (and stuck for quite a while). One thing I noted early on in numbering was that the single cells in row 2 and column 4 had to go in the grey cells of row 1. This differentiated them quickly. For the shading of r8c5, I was able to determine it earlier by noting that row 3 was already a 42 clue, so shading the cell grey would have given me a second clue of the same total. Such a fun puzzle!

@Coldsuu 8 ай бұрын

There's a prophecy you missed at around 1:35:00, don't blame you for missing it but I found it pretty funny. Earlier in the puzzle you offhandedly joked once you finished the bulk of the shading that "we know some weird things now, like these 2 cells are not the same digit" and you chose a 1 as a random example to show that r3c9 and r9c7 could not be the same cell, because it would force an identical total into r3 and c7. Fast forward to 1:35:00 you're looking for where 1 goes in row 9, it clearly can't go into c1, so we're left with 3 cells cross boxes from box 8 to box 9, but you can actually eliminate r9c7 by exactly the logic you found so long ago, if you put 1 there, 1 is forced into r3c9 of box 3 and the puzzle breaks.

Love this puzzle. Is there a reason at 1:00:00 that you can't have an 8th 3-cell region if you then didn't make the 2 orange lines 2-cell regions? Then you would have a total of 7 2-cell regions (less than the max), and then 8 3-cell regions. Then R3C9 would be green. You would then get R3 all green, which is not allowed since C3 is all green, so Simon got the right answer, but was it for the wrong reason?

@EdoTimmermans 8 ай бұрын

If R3C9 is green, then R3C1 turns grey (R3 cannot be entirely green), causing the quotum for 2-cell to reach the max and thus reaching too many 3-cell regions, so R3C9 must be grey. But it was potentially confusing indeed, as I was wondering the same at first sight, as Simon did not mention this at that point (already he had explained earlier on that either R3C1 or R3C9 must be grey as R3 cannot be green).

Well done, Simon! Fantastic solve, again. Love the longer videos, especially if I can keep up with your logic. Which mostly I did on this one. No way could I have solved it. Although I did see the start in row 1. I think we didn't get the confetti from the 3 in the corner because the software assumed the corner of the grid was the black cell in the bottom left of the grid. If it had been a 3 in the right bottom corner it would probably have worked.

54:37, an easier logic for me was that c2 and c6 couldn't both contain two 3-cell clues without producing two 45s. This means they contain that last 2-cell clue. Then r6c6 could not create another 2-cell clue, and this forces c6 to contain the eighth 2-cell clue, with a 3-cell clue.

I couldn't initially see where you were getting the two 45s, but I see it now. If c2 and c6 were both two 3-cell clues, then they would both have greens in row 9, which would have to connect, making both columns 3 and 5 complete 45 rows. 👍

I actually liked the length of the video. Plus i think the ?'s is what's hanging up the software. Loved the solve. If you ever want to do another one this long, go for it.

@michaellautermilch9185 3 ай бұрын

I took a different path towards shading the grid. By seeking out exactly 15 instances of 2 cell clues or 3 cell clues, you can resolve column 2 and column 9. This helps because you dont need to identify each 2 or 3 cell sequence initially, you just need to limit the total of both to 15 instances or less. A few places where the sequence can be "2 or 3 cells" makes counting 2 cells difficult, bit they clearly contribute to the 15 total.

I've watched up to the 1:09:00 point in the video and this is the point I got completely stuck. It's nice to have it confirmed that I'm on the right path up to this point. But now I'm going to bed, and will see if I have any further inspiration when I look at the puzzle with fresh eyes tomorrow.

One thing keeps me puzzled however, I was shocked(!) when it said it was was not the correct solution! But the solve counter says it has been solved 22 times. How is that possible?

@ 56:19 - "oh no, it's a question mark" - yes, but the cell below it isn't, so it has to extend to the right, making C3 the 45. Why would you look at R8C2, but not also look at R9C2? @ 1:05:29 - what are you talking about? You can't have two 2s in the same box. The first rule s "normal sudoku rules apply". This really was a brute of a puzzle. Sadly, you missed my favourite bit of logic which resolved the 19 and 20. If the top was 469, you ended up needing two cells to be 8 in the same column. Although I was delighted to solve it, I can't say I look forward to more like this. I got through the shading quite easily, but the amount of graft that was needed to get going with the numbers was a bit too much to be particularly enjoyable for me. Once there were enough deductions to have some traction, it wasn't too bad though. I can't imagine how one goes about setting a puzzle like this. The intricacy was incredible, and for it to be possible to get started, and for it to still hold onto some secrets right up to the end was impressive. What I found interesting was discovering that, if you stack the numbers into the fewest possible cells, there are 9 1-cells, 8, 2-cells, 7 3-cells, 6 4-cells, 5 5-cells etc.
