I have to ask shye, did you use the type 3 Phistomefel ring when setting the puzzle? (ring pushed all the way out and boxes pulled in) I found it immensely helpful in spotting the logic and immediately extending it to the far corner of box 7. The cross check was slightly helpful toward the end, but Simon made it clear it wasn't necessary to finish the puzzle at all.

INCREDIBLE logic from shye. Great solve Simon! I always love seeing shye’s puzzles featured

It was a brain cracking 52:47 but I got there. I got the 89 pair in box 2 quite early on without cottoning on that the 1/2 duplets in row 2 and column 8 were a telegraph. Once I saw that, my mind went in muttering quasi-Simon mode and I encouraged myself with the occasional 'Hang on!' and 'Now, *that* is almost interesting...' - and then the peripheral penny dropped. I had reason to regret that my cooker is electric which limits the linguistic flavour of my jubilant shouts. The latkes weren't any less tasteful. What a puzzle! My logic was very similar to Simon's whose solve was the usual joy to watch.

How Simon manages to always solve these by coming up with brand new techniques is stunning to me every time. He’s awesome.

I actually managed the jovi_al puzzle in 38:29. It does require looking ahead a bit, but since there are a lot of squares with only two options, I didn't find it too difficult to visualize. Very satisfying puzzle to solve, some beautiful logic in place in my opinion. SPOILERS AHEAD: basically the break in is that if you place a 9 in either r7c4 or r8c4, it forces all the cells in box 2 and 8 in such a way that there is no room for a 5 in column 3 (r9c6 becomes a 5, ruling it out of r9c3 and r2c5 becomes an 8 forcing the 8 in box 1 into r1c3, thereby eliminating the possibility of placing a 5 in column 3). I wonder if this is what Mark found, because I cannot believe that Simon would not be able to find this.

Interesting solution. I solved it by spotting a chain involving 5's and 8's. Basically if r1c3 is a 5, r9c6 is a 2, and if r1c3 is not a 5, r9c6 is also a 2.

I think this is probably the first time i have EVER solved a puzzle quicker than Simon! And a classic sudoku no less (which I typically am terrible at!). I like to think it will be a recurring trend but I am far more realistic than that! Nonetheless, I am taking this small victory!

I like that Simon said, “that’s a five by sudoku” in a classic sudoku puzzle

I got the same 1-2 logic but I did it bit different. I used variation of the phistomefel's. Boxes 1, 3, 7 and 9, four most center cells have to be found in box 2, 4,6 8 in row1, column1, row9 or column9 and in the 4 corners of the sudoku. This is very powerful for the solve. You can immediately notice there is something going on with 1-2 combo and even in the later parts of the solve this logic helps a lot. But yeah it still took me 50 minutes, it was a hard one.

Wow, I couldn't believe I finished this puzzle within 30 minutes. Truly extraordinary and elegant logic.

Simon! My heart was in my mouth when you said 468 and put 469 pencil marks in box 9!

I Finally got my Cracking the Cryptic Sudoku book in the mail. Thanks for all the effort. in a word Awesome

wow, l actually could find all those tricks in 16 mins, than ofc couldnt find that naked 5, but actually feels good to do something almost as fast as Simon

A shame that the solve from 35:00 onwards wasn't logical due to the 8 vs. 9 misclick a bit earlier. But at least all the hard stuff had already been done by that point.

I did it huzzah! I confess I check my progress against Simon to ensure I don't spend hours trying to solve it with an early mistake. Thank you Shye

29:46 for me - it took me almost 20 minutes to figure out the 1&2's and then it fell into place from there. Wait, did I get it faster than Simon? I must be having as especially clever day today.

This sudoku took me about 35 mins to figure out, but the second one, I thought I was going to be majorly stuck, but I managed to get it in 20 mins and 19 seconds! Once I figured out 2 of the 9's everything just fell into place, one digit at a time. (it was a little hard for me to see because I had to color in some cells to not confuse my pencil markings). For something so hard, I was impressed with myself on the time, and no hints with that! I think I just miraculously came across solution as a beginners luck thing, but watching enough of these videos gave me lessons in different techniques I don't typically use, and I happened to decided to use one of the harder ones for me to usually see (I'm half blind) for the Jovi_al's sudoku and would have never used it if I hadn't learned it from this channel.

@GeorgeFoot

2 жыл бұрын

Yes, for the second one the break-in doesn't seem as complex to me as is implied. It was certainly hard to spot, for me, but not harder than usual for this channel. It revolved around noticing that having a 5 in row 3 column 5 forced 5s in r9c6 and then r1c3, leaving boxes 1 and 2 both requiring an 8 in row 2. So we can exclude 5 from r3c5 and the rest of the solve is fairly routine.

@Nekomancer_Evei

2 жыл бұрын

@@GeorgeFoot sounds like a different approach than I took, interesting. I'll have to give it another look to see how you saw that. ^_^ For anyone curious, I pencil everything in at most of 2 options in each box, then I went through each line (vetically/horizontally), and colored by their number where 1-9 can only fit in two spots, and saw that 9's made a weird pattern. there was only two spots in I think row 2 and 8 that could have two solutions for 9 to go, and the other options were in fact shared in column 5. Hopefully that can assist others if they see the pattern that way, and decipher from there. ( I don't typically scan the rows/columns like that, and this channel was the place that taught me that technique, but I rarely use it because it's hard on my eyes to see, hence the coloring option to help make the noting a little easier to stand out).

@Nekomancer_Evei

2 жыл бұрын

was double checking how I did it, and I forgot hey didn't share column 5, they were offset because box five column five is a 129 triple. opps, sorry if that threw anyone off, but there is a pattern there if you look, I don't know if I can explain how I figured out the placing of the 9's, but those 2 9s were my first digits. Just tried the 5s route, yeah, that's a lot easier to see. lol didn't even noticed that, when I colored in 9s could only show in r2c6, r2c8 and r8c2, r8c4, the pattern stood out much easier than 5s, but processing it was much more difficult, but once you showed the 5s, yeah, so much easier to plop everything from there. still 20mins and 23seconds but I lost some time trying to see the route with the 5s, but once I saw what you meant with the 8's yeah, it just flowed much more smoothly than my route. Intriguing.

Shye's puzzle has a wonderfully logical solution path.

@7:53 Simon mentions Shye telegraphs what she's trying to get you to see. That made me notice that in box five the 4,7, and 8 are pointing towards box three. Then I saw that the 1 and 2 in both boxes one and six also point into box three. I don't know if this would still have been solvable without the arrow, but that was 100% what clued me in.

Oh my god! I managed to do that in 31minutes without even sneaking at the video (I did see that it was one of this computer knows nothing puzzles) and I did remember you saying last time one of these came up that the 1&2 was a hint from the setter so once I spotted that middle cell I started with the colouring. What a puzzle and amazing that I could solve it - this channel has taught me so much (I mean, extreme sudoku solving isn't an amazingly transferable skill but I'm happy!)

This puzzle was mind-bending for me, haha! Very nice, shye

The puzzle : “Normal sudoku rules apply” me : ah finally one i will be able to do… wait…

When I did this today, I forgot that I'd done this six months ago or so, but no matter. I solved it anew, with no memory of my previous attempt. My Sudoku has definitely improved, thanks to this channel. There's still room for plenty more improvement. Around 9:00 you gave me the heads-up with the 12 pair placed at the center. I had already noticed the 12s in boxes 1 and 9, and placed the 12 pair at the center, but didn't make the connection on my own. I needed the heads-up. With a little TLC, I managed to place the same 12 in the top-right and bottom-left corner -- the same digit as the center. (You need to go horizontally and vertically to force it there.) I called that digit A, leaving B for the other 1 or 2. Some time later, I had to show that B was in an extreme cell of the horizontal and vertical cells. The rest was grunge, frustration, and over-pencilmarking. But I solved the puzzle. 18:10 In place of using 1 as a help to visualize, use A for the number in question and B for the other number. Also IIRC, a B in any cell other than an extreme cell of the middle row forced B into both extreme cells of the middle column. 28:20 The 12 pair out of nowhere, I placed as A and B (not an AB pair). Using A and B, I could fill out the entire middle block and the entire middle column except for a 7B pair in the extreme cells.

I wouldn't call jovi_al's puzzle monstrous difficult. I just made my usual pencilmarking and checked where would I put 3. I marked a solution, then I marked where would I put 5. Then I noticed I couldn't put in 8, and that solved my cells in the middle. After that, it was normal CTC sudoku.

Only Simon can gain understanding of where 2 digits go by using 4 different colors. Simon, you have an amazing brain, but how it works alludes me.

I noticed right away that this puzzle reminded me of another one some time ago, where r5c5 and r1c9 had to be the same digit, and had to be either a 1 or 2. Sure enough, the same was true for this puzzle, and both of those digits had to be a 1 or 2. 2. However, r9c1 also had to be the same of those digits! Symmetrical reasoning at work. 3. Then I looked around, and eventually noticed that r9c5 and r5c9 had to be the other of 1 or 2. 4. That meant I was able to cross certain other digits off, and get some numbers in the ring. 5. Then, I used the numbers found, the given digits, and the phistomefel ring, to solve.

30:35 Simon: 'I'm tempted to look at row 2 or box 2' - Yes! 12 pair! Simon: '9 here and let's ignore the box for now' Mental power was probably drained by finding that awesome 12 pattern that I would've never found.

The logic to jovi_al's Negativity jumped out and grabbed me by the ears the minute I looked at it. There are days when autism is a superpower.

Looks like a mistype in box 9 (469 for 468) led to 4 being placed prematurely, forced by the 69 in the row. But I could see that if it were correctly marked, the 4 in column 3 would have taken care of it anyway.

12:36 for me. Probably the first time I don’t struggle with a hard classic sudoku, I hope it means I’m getting better at those as well. Edit: 14:33 on jovi_al’s one. Didn’t find a single piece of logic, just tried for a few minutes and then bifurcated. I’ll go back to see if I can find anything at all.

for some context, king da ka is a roller coaster at six flags great adventure. it’s pretty simple-you get pushed up a huge slope, go down a vertical slope, then go over one more hill before it ends. it’s famous for being very tall and very fast, though i don’t think it’s the tallest or fastest any more. worth a visit if you’re ever around new jersey!

If Shye can create these and you are able to solve them you both are "other-worldly" I can't even follow your logic train as I'm listening let alone figure it out without the training wheels.

The other puzzle you displayed in this vid, I did it as I watched you, took me 12 min

I did this as 1-2 coloring puzzle. You could eliminate 12 from top center like that. I don't know if that was bifurcation or not but it helped to solve the puzzle.

4:18 - 4:30 "And it was in this position that we have a brand new Simarkism"

Managed to solve it but holy hell what a challenge - by far the hardest puzzle I've solved on my own and it took me hours.

Very interesting. Similar logic to a couple of Shye's other unsolvable puzzles, without which I wouldn't have had a clue. It took me longer to spot the full 12 interaction, but after that, possibly because I'd spent longer pencil-marking, it seemed to finish easier than Simon's.

This one hurts my brain more than all the other ones with insane rules

30:55 Here you didn't spot the fact in the 2nd 3x3 box that the 1s and 2s were blocked into the 3rd row, which will give the 8 and 9 in the 2nd row! And it would've helped you with the coloured boxes too!
