I've noticed that as Simon reads through rules, he sometimes will use the same example to show the audience. Like with Yin Yang he always draws an E shape for the example. I think it would be highly entertaining if a setter found a few rules that Simon uses the same example on each time, then make a puzzle that solves into the examples that he gives at the start.
Like I wonder how he'd react if a puzzle with a Yin Yang ended up having the E shape he always makes on it.
You hear Simon's voice in your head too? My Sudoku thoughts have an British accent and use words like "bobbins", which I would never say out loud.
what a beautiful puzzle! I was stunned at the beginning and having a hard time to find the break in, but then the puzzle flowed very nicely. i was surprised how useful the nabner lines were
I took almost 2.5 hours to do the puzzle, and I needed Simon's heads-up about the interaction among the two straight renbans and the nabner to get started. I was hoping to finish in time to catch the livestream but alas.
3:50 Are nabner lines considered "standard variants"? Also, the blue line is the only thing that disambiguates the high-low symmetry of the puzzle. So I began with a particular choice, and once I got a 13 domino on the blue line, I flipped the digits.
17:10 If the break-in was the renban line in row 1, the line in column 7, and the nabner line in block 1, I needed Simon to point it out. I never got remotely near it.
18:20 The puzzle almost reaches those extreme worlds.
18:40 Actually, the short green line forces 5 into column 7 in the block well before the end of the puzzle.
20:00 Simon shortly reaches exactly that issue. And that's where I abandoned the video and went on to solve the puzzle.
25:00 It was a little later than I remembered. I noticed that I made perhaps an unwarranted assumption that turned out right, once I returned to the puzzle.
26:50 No, it wasn't an unwarranted assumption. I thought about that particular issue -- the four-cell line couldn't be 1234 or 6789 because it used too many low or high cells.
28:00 Such subliminalities are usually lost on me, autistic as I am.
30:00 I went straight to 12345 in the row 1 line, and 5678 in the column 3 line. That was before I flipped everything.
37:00 Contour integration? Completing the loop out at infinity? I haven't done that in a while, and it's been a *long* time since I've seen the proof of the residue theorem. I tried at one time to verify the theorem for a particular integrand numerically, but I got nowhere.
43:25 I used the symmetry, and arbitrarily chose one possibility. It forced 13 into the blue-line domino, so that's how I knew to flip the digits.
46:30 Here's what I did (the flipped version): the nabner line in block 1, below 5 must be 2 or 3. Above 5 must be 7 and 9. In block 7's green line, 9 has to be in column 2, at one of the ends of the line because the ends see the entire renban above. This means that 59 on the nabner line is in column 1 and 7 and (2 or 3) must be in column 2. That leaves 68 in column 3 of block 1, and 79 on the blue domino below.
1:01:40 Oh? Does that mean that I blundered in ruling out the 4 (6 for me) from the line early in the puzzle? I think that I can see it now.
1:18:25 When does Simon realize that 5 goes in R7C9? And then in row 7 in block 6, thanks to the green line? The digits in a blue cell are sometimes difficult to see. For example, one of a 23 pair in column 9.
Thanks, great solve, look forward to longer videos, like 3,5 hrs ones… 😊
first time i solved it i was an idiot, so i put 7 and 3 on a whisper so i substituted 3 for 2 in a bunch of cells, ended up thinking you made a mistake and the puzzel had multiple solutions :P that was silly, the break in was pretty cool, the nabner is common to column 3 and row 1 outside box 1. nice break in , didnt make my silly mistake until much later so it didn't spoil the break in which was nice.
My break in was a bit slower. Even though I found it, in my opinion at least, quite fast. Can the column 3 renban avoid a 5 since in box 7 it can't be all one colour? Since no, that puts 5 on box 1 nabner, forcing 4 and 6 to be outside. But row 1 renban and column 3 renban needs either a 4 or 6 to work.
Oh, and now I see that was similar to Simon's break in as well.
Two things about the Box 9 whisper.
C9 has four lower digits and hence R7C9 is 5
5 cant go on whisper in Box 6. So goes in C7
R1C8 is 5. Therefore R1C7 is 68
Now, R8C7 has to be LOW becsuse there are four high digits in the column already. 79 pair and 68 pair
really cool puzzle :)
I spent much time yelling at Simon on the screen for ignoring the blatantly obvious 23 pair in column 9 that would have cleared up a bunch of stuff. Unfortunately Simon tends to mostly scan horizontally, not vertically, and using the blue background probably did make one of the 23 squares invisible.
Simons break-in was way to complicated. First thing I noticed was that the top renban needs a 5. Next, if the renban in box 7 didn't have a 5, it would contains 3 digits of the same polarity in box 7 breaking the german whisper. Now 5 is forced onto the nabner in box 1. This means that 4 and 6 cannot go there. If you place both 4 and 6 in B1R1 you break the top renban, and you put them both in B1C3, the renban in box 7 is broken. so one of them must go in B1R1 and the other in B1C3, forcing the renbans to go from 5 in opposite direction. R1C3 will now be the same polarity as the renban in box 7 using all 4 digits of the same polarity. a nabner with a 5 needs either 7-9 or 1-3, and one digit of the opposite polarity, which the same as the entirety of B1R1, making R2C3+R3C3 the rest of the same polarity, making the blue line in box 4 either 1-3 or 7-9. The blue line has 3 cells in box 2 for a minimum sum of 6. 1+3 is only 4. so it must be 7-9. the polarity of the renbans are now forced.
What you described is almost identical to what Simon did…at least what he said he should have spotted once he noticed the polarity conflict with the whisper. Like…exactly this.
@@MaxPower417Well, I didn't watch neither the original video nor this for long enough to get to that point.
I have grown tired of Simon spending way too long time on explanations on how the rules work, joking about a "secret" that is one of the first things you ever learn about when it comes to math, attempting to place a 3itc, singing song and reciting poems, and a lot other unnecessary stuff, butt fails to resolve a 2-4 pair, despite there being a 2 right next to one of the cells.
Sometimes, after having solved the puzzle, I watch the video to see how Simon did it, only to find that within the time that I used to complete the puzzle, simon is still stuck on the very first thing he spotted.
