** TODAY'S PUZZLE **
We don't often feature classic sudokus on the channel nowadays such is the extraordinary quality of the sudoku variant scene. However.... shye is a constructor of quite exceptional brilliance and her classics are always worthy of attention. This one, called White Marlin, is yet another example of a puzzle where a computer needs to indulge in all sorts of odd quasi-guessing techniques whereas a human being can find a beautiful and elegant way to solve it... are you such a human?!!
You can try it at the link below:

Normally when I see a Simon video under 45 minutes or so, I'll give the puzzle a shot (assuming I'm not too busy). Your puzzles are an exception to that rule though, because previous experiences have taught me that your logic is so beautiful that it flies over my head every time. I respect your humility, but just know that every word of praise that Simon said in this video is justified

@@shye229 This could be solved logically by an algorithm if someone decides to implement it. The common algorithms only check for patterns on digits, but you can also check for patterns on colours.

Fun fact: the B-side of They're Coming to Take Me Away Ha-Haaa! was the same "song" played in reverse, and the label was a mirror image of the A-side. This was interesting. I didn't quite get there the same way, but I thought there was something hincky about 6 & 9, especially once I spotted the R6C1/R4C9 pair. Once I realised they had to be different, it was just plain sudoku. I'd be surprised if a computer solver couldn't spot this, it didn't seem too difficult to work out that those two cells had to be different. I love the way that Shye is still finding new ways to push the boundaries of classic sudoku. Whilst solving this, I had an idea for something that I've never seen in a sudoku. I wondered whether this was perhaps what Shye was doing, but it wasn't. Unlike many of my bright ideas, I wrote this one down while it was clear in my head, so that I won't forget it. I'm going to try to set my first sudoku using it, to see if it's possible. If I get into trouble setting it, I may pass the idea onto Shye.

@fluffycritter Жыл бұрын

This one was really fascinating. I loaded it into Good Sudoku which insisted that it wasn't solvable, and while I was stuck on things for a little bit, Simon's observation about the 6/9 "conditional x-wing" made the whole thing fall down *immediately* thanks to Good Sudoku's solving tools - which then refused to believe that I'd *actually* solved it, so it won't actually save my solution or time (or give me a score).

@RichSmith77 Жыл бұрын

I managed to solve a Shye classic! Well, almost. With the smallest of suggested hints from watching Simon - I just needed him to start pondering on the possibility of a 6 x-wing in rows 1 and 9, even though there wasn't one. I had found that r4c9 and r6c1 were restricted to 6 or 9 only beforehand. I did give up, though, and had started watching Simon up to 11:15. Then paused the video and thought harder about 6s and 9s. Very satisfying when I then worked out r4c9 and r6c1 had to be different, and that r4c3 had only one candidate. I'm not proud. I'm counting it as a solve. 🙂

Brilliant construction and well worked out by Simon. It's interesting that if you put the first derived digit C3R4 as an extra given, the puzzle drops from super-extreme to medium in difficulty. So it's really the 69 logic that eliminates two out of the three options for C3R4 that is the magic key.

Andrew Stuart's sudoku solver does actually solve this one, but through some crazy forcing chains. It finds that the special cells have to be 6 and 9 instantly, and I'm guessing that it understands that in either case, the other red cell cannot be same digit as the first, but I guess that it only understands that within the context of exploring individual logic steps, and so it doesn't combine that with other logic.

6:30 "It will not be your friend." I've found that triple pencilmarking corner cells helps me catch things that I would find a lot harder otherwise -- triples, X-wings, swordfish, etc. 17:28 I paused here to see what I could do with the pattern I had of the bottom row 1269 quad and 69 cells in R6C1, R4C9, and R7C8. I didn't notice any advanced pattern specifically, and no chain of logic worked with me. Therefore, I quadfurcated on these options for the bottom row: :: 69 in cells 1 & 9, 12 in cells 4 & 6 (two 69 pairs) :: 12 in cells 1 & 9, 69 in cells 4 & 6 (no 69 pairs) :: 2 in cell 1, 69 in cell 9 (69 pair in column 9) :: 1 in cell 9, 69 in cell 1 (69 pair in column 1) The first three broke the puzzle. The last solved it. That was probably karma for my choice to quadfurcate. 17:58 That was nasty of me, wasn't it? I clicked to pause the video and the flaming error message flashed in. 18:40 Have you noticed that R2C2 is a given 6? 21:10 6s and 9s are the right thing to look for. Just expand your field of search. Also, centermark the bottom row. 22:20 "By Sudoku"? Would anything be otherwise in classic Sudoku? 23:10 Yes! You found the 69 cells. 23:50 I see it now. The conditional X-wings force the two 69 cells on the edges to be opposite. (Later) This time, I managed to solve the puzzle without -furcation. 6s and 9s were restricted in rows 4 and 6. Several pairs, triples, etc. later, the puzzle finally collapsed. 38:00 The first solve, I had the 69s and the bottom row. I didn't think of the top row interacting, and I doubt I would have discovered the conditional X-wing in any case. For me, the conditional X-wing did establish that the 69 cells were opposite. Nice video!

@davidh.4944 Жыл бұрын

I came _very close_ to figuring this one out on my own. Close, but no cigar. I could tell that it hinged on that central 69 pair being different, but I could not quite figure out how to prove it.

Once I got the 69s left and right, I just tried each out a few steps. 9 on the right was unproductive but 6 led me all the way home.

24:36 snapshot : I think there is no immediate need to find that 69 pair un the rows 4 and 6. The point is that, in row 1 and 9, therecan be only one 6 and one nine in columns 1 and 9, so there are two missing (there must be two sixes ant two nines in these rows). That gives an virtual X-wing in sixes between column (1 or 9) and 6, and another virtual X-wing in columns (1 or 9) and 4.

When solving this I, for whatever reason, ended up going down a path of logic (which was pretty much 1 fork of a bifurcation) where I had gone "If I can prove x, then lots and lots of stuff happens" (I've forgotten what x was exactly unfortunately, something to do with 6s and 9s). I ended up getting so much stuff from that assumption that I ended up thinking that this is surely the correct path and decided that, rather than going back to prove x and losing my progress, I would just finish the puzzle and then later go back to the start to try and prove x. The entire puzzle solved except for 2 digits, one of which was r4c9 which had no possible values. Which meant that my assumption, despite solving 98% of the puzzle, was actually false. This is utterly bonkers. 1) I have no doubt that the computer struggled really hard if there are almost perfectly valid (but not quite) configurations consistent with the clues given 2) This was the thing that made me look at r4c9 in the starting grid. Since I knew that ANY solve would have to look at it so as to eliminate the almost-perfectly-valid solution I had found.

OK who else spent ages trying to play the same trick that Simon did with the 69 pair but on box 6 and box 9 before finding the other 69 pair to play with in box 4? Nice work as ever from Shye.

@pairwin Жыл бұрын

I can’t believe I solved this on my own. Shye’s ordinary sudokus kill me. I used set though. Highlighted C1,4,6,9 and R1,4,6,9 and removed the overlaps. If you had the 69 in R6C1 and R4C9 then it became really clear the 6 and 9 had a big constraint in boxes 4 and 6. Not sure if that was the intended solve but it was easier than what Simon did.

@werefrogofassyria6609 Жыл бұрын

@Adrian_Grey Жыл бұрын

A marlin is closely related to a swordfish. It's not QUITE a swordfish, but it looks like one. And the pattern with the 6 and 9s is kind of an offset swordfish. If the 69 pair in boxes 4 and 6 were in the same row, it would be a true swordfish.

Begin with the preliminary sweep looking for all available splits and bivalued cells : [378] splits in B5 ; 1 on col3 B4 btw rows 5&6, and splits in B9 ; 2 splits on row 2 in Box2,followed by 4 on col6 B2; 2 splits on c7B6 between rows 4&5; 2 splits in B7 and on c2 ; 3 splits on r8B8 btw cols 4&6; on r2B3 btw cols 7&8; on c2B4 ; 4 on c1B4, by virtue of four 4s given on rows 1689,all off c1 => 4 splits on c2 ; 4 on c8B6; on r7B7; 5 on r3B2 btw cols 4&5; on c9 ; 6 splits on r1@ (16)&(19),(highly relevant); 7 splits on c1 @(11)&(18); 8 on c9 B3 and on c7B9, by crisscrossing btw the two 8s given on r9&c8! The bivalued cells uncovered by direct point counting are : Cell(32)=[49], (49) = [69] (will play significant active role); (82)=[59]; (78)=[69] (weak link). Note how 2&4 are intertwined; soon 6&9 given in B5 will together prove their strength /prowess. Here’s a nittygritty observation : 9 @(32)B1 would lead to 9 splits on r1@(14)&(19) and => 4 on c2@(72)=>2@(91) by cc of the 2s given outside of B7,viz: on c3&r8 ==>9 splits on r9@(94)&(99) resulting in Wings for both 6&9, sharing the rows 1&9,with the common col9 !! ===> !! cell(49) = ZERO!! Henceforth 9 is eliminated from (32),leaving 4 at (32) !!==> 4 on r7@(73) and 4 in B2 on r2 forming tcp with 2 btw cols 4&6, by v of the uncovered 2&4 on r3, and the two given 2&4 on r1&c5, all outside of B2, and with 4 given on c4 outside of B2 ==> 2 on c6B8 btw rows 7&9. Now another nittygritty : 2 @(91) would lead to [23] tcp on c2B4, followed immediately by [15] tcp on c3B4 btw rows 5&6 !! [CIY = check it yourself! Hope u succeed!] (Hint : there’s where 15 given on c1&on r5 come into play, both out of B4) The uncovering of the above makeup is a setup for what is abt to happen: With 2 at (91), we build a Wing in 6 along rows 1&9 and cols 6&9 ==> no 6@(49), but 9 ==> 9 on r6@(61) and on r9@(94) (now u see that 2@(91) block both 6&9 @(91) ===> in hot pursuit, 9 on r1@(11),resulting in two 9s on same col1, a No-No!! Therefore 2 in B7 can’t be @(91) but @(72)! ==> (91)=[69], 2 on c6@(96),& more significantly [24] tcp on c1B4 btw rows 4&5, by v of [24] uncovered on cols 2&3,& given on r6, all three outside of B4!! To be continued in the next comment box!

@ckoh010 Ай бұрын

Continuing from above : With eyes wide open and in hot pursuit, 8 on c1 is at (11), by v of 8 given in B7& on r6, both off c1 ==> 7 on c1@(81), leaving 69 cp on c1 @(61)&(91), and leaving in B1, [79] tcp on c3B1 and 8 on c9@(29) => 8 in B2 on r3 forming triplet with 15 (note [24] uncovered tcp on r2B2 btw cols 4&6 => 1 in B2 on r3) ==>6 in B2@(16)!!, by cc of the two 6s given on r2&c4 outside of B2, ==> 6 in B3 on r3, plus leaving 79 cp in B2 @(14)&(25), and on r1 @(14)&(19). Note 31 uncovered on r3 & given on r1, both off B3 ==> [13] tcp on r2B3 btw cols 7&8. Several ways to proceed : An educated guess is put 9 @(14) which would lead to [69] tcp on c5B8 and 1@(94) ==> [18] tcp c7B9 ==> [38] tcp on r8B8 btw cols 4&6, leaving [57] tcp on r7B8 btw cols 4&6 ==> 7@(55) ===> cell (25) = ZERO!! Therefore 7@(14) => 9@(25)& @(19) => 6@(49), plus [67] tcp on r3B3 ===> [68] tcp on c7B9, by v of 6&8 uncovered on cols 8&9 outside of B9 ==> 9@(78) and leaving 1 in B9@(99) ! ==> 9@(94) & 6@(91), leaving 9 on c1@(61) and [59] tcp on r8B7 btw cols2&3 ==> [35] tcp on c2B4, followed by [16] tcp on c3B4, by v of 16 uncovered on r4 outside of B4!, leaving 8 in B4@(43) , in hot pursuit, 8 in B5@(55) =>7@(66), leaving 3 @(44)! ==> [67] tcp on c5B8, by v of 67 uncovered on cols 4&6 outside of B8, followed by [13] tcp on r8 B8 btw cols 4&6, leaving [58] tcp on r7B8. Note 8 uncovered @(55) => [18] tcp on r3B2 , by v of 18 on c5 outside of B2, leaving 5 in B2@(35). At this stage towards the endgame, the Bottom Block is completely broken up. So are the Boxes 123. Now time to clean up B6. Note 1 uncovered @(99) leaves [57] tcp on c9B6 btw rows 5&6, followed by [29] tcp on c7B6 btw rows 4&5, by v of 29 uncovered on r6 & on cols 8@9, all three outside of B6; also 1 on r6 is @(67), as confirmed by three 1s given on r4,& uncovered on r5& on c9, all out of B6, leaving [34] tcp on c8B6 btw rows 4&5. All done!! It’s always fun to see how all the remaining TCPs are broken up with their respective danglers. Happy journey!

I managed to solve it without spotting the intended logic. I was able to eliminate a 2 in r9c1 which gave me a few digits reducing r4c3 to 68 and then that whether it was 6 or 8 r9c9 was always 1. If it was 6 r9c9 was 6 and r4c9 was 9 and if it was 8 r7c7 was 8 and r7c7/8 were a 69 pair. It unravelled fairly easily from there.

I wrote my own Sudoku-cheating program, so I know exactly the problem it had with this puzzle: it is only ever considering one digit at a time, and it has no sense of curiosity. Unless you know The Trick, there is effectively a deadly pattern on sixes and nines. You only need to play about with digits for a moment to realise that R6C1 and R4C9 have to be different, but you have to think of both digits together: if you fill in either one of those cells, you quickly run out of steam trying to chase it around the grid; but writing the same digit in both cells converts just enough potential energy to kinetic energy for the two to collide! And it's making my brain hurt trying even to begin thinking about how to get a computer to deal with that sort of situation .....
