48:00 I love the few times when I am able to see something Simon doesn't (very few times) that he then independently proves with much more complicated logic. 15 minutes earlier, you determined that between r7c6 and r7c8, one of them had to be an 8 and the other one had to be a yellow. So how could r7c6 ever be blue? It can't be blue if it's yellow and it can't be blue if it's 8 because blue already has an 8 pencil marked in row 9. Therefore, blue can't take r7c6 and needs to take r6c5.

But we know that one of said cells must be 8. This cell can't join to neither blue nor yellow having their 8s in r8 and r9. Therefore r7c6 can't be blue but r6c7 must be blue.

I disambiguated a location or two of regions by fixing 9s in the grid. Then a region has to contain an arrow, a circle, and a 9. (The possibility that two arrows and two circles could be in a region didn't occur to me. I'm treating it as an oversight of the rules statement.) Allowing the arrow in column 9 to have a 1 gave me buttloads of trouble, by forcing a 1 in R9C8. The arrow has to be 234, and find a circled 9 to match. (It's not orange.) I also managed to make progress by labeling the digits in the two 8-sum arrows other than 1, ABCD. A + B = C + D = 7. 47:55 As others commented, that cell already had to be blue, because the other candidate blue cell would contain an 8. 1:19:20 Nice to see my final solution matching the video's.
@brianmcadam4432 жыл бұрын
For anyone that wants a cleaner way to get past Simon's extensive hypothetical at around 55 minutes, first consider row 9, specifically where 6 and 7 must live: in blue. Then consider where 6 and 7 must live in row 7. They are not in blue. By arrow sums and the existing pencil marks, 7 *must* reside in the one green square in row 7. And then 6, by elimination, must be forced into red, where it will force the arrow sum and the repeated digit.
@CrypticCL2 жыл бұрын
Brian, do you mind explaining why there can only be one repeated digit, and not two (at that stage of the puzzle)? Simon didn't specifically explain it - other than mentioning Schrodinger, as though there would be one cell having to contain two numbers simultaneously..... but I don't see why? (e.g. 1,2,6 = 9 total in the first three cells of Row 7, and then 5,1,2 = 8 in Row 8 beneath it). It seems to me that (at that stage of the puzzle) two digits (1 and 2 in my example) could have been repeated without clashing.
@brianmcadam4432 жыл бұрын
@@CrypticCL It basically comes down to the law of leftovers for Irregular Sudoku, and the extent of the drawn regions. Yellow in the bottom right is confined to rows 789, even though the last cell hasn't been chosen. So any digit that is on both the red arrow and the green arrow, where does it live in yellow? In row 9. Then where does it live in blue? *Above row 7* because you've already allocated that digit for rows 789. Well, given how many cells blue already occupies, there is a maximum of one empty blue cell above row 7, the one immediately to the left of the 9, which would complete the blue region. So for the 125/126 example you posited, both 1 and 2 would be in row 9 in yellow, and either doubled up in R6C5 (nope) or left out of blue entirely (nope). So you can't repeat two digits. (this is not exactly the proof that Simon uses I think, but it's the same concept of comparing groups of rows to groups of regions)

at the 47 minute mark when deciding the final blue cell an easier way of seeing it is with the yellows. The combination of needing a yellow and an 8 (r7c6 and r7c8) in row 7 means blue could never take r7c6, as it obviously isnt yellow and it already has an 8 pencil marked within the region. This forces the blue into r6c5.

Incredible. You were nearly at an hour before it seemed that you were confident that you would complete the puzzle. Of course we knew there was a happy ending since we are seeing the video, but it did seem as if the logic of figuring out how to proceed after getting the 6 of & 7 in row 8 was very difficult - maybe the hardest logic that I have discerned you working with on this channel. But you did it, and really, it was like a card trick: you pulled out my card from behind my own ear and I watched you do it, but I have no idea how. "I am so slow.

Hi Mr Menace, thanks for another incredible sudoku. I hope you don’t mind but I just wanted to pass on a little feedback. I believe this puzzle is perhaps a case of having one rule too few, namely ‘no region containing multiple bulbs or arrows’. To explain, I really enjoyed solving the sudoku given a one-to-one correspondence of the arrows and bulbs, with each pair being assigned to its own region, only to find out that the rules read differently when watching Simon’s solve. As a budding puzzle setter, the truth is that not everyone understands rulesets so easily! I am quite a deep thinking and logical person and yet I would almost never have taken the rules to mean anything else but that each arrow and bulb were connected within their region (it actually took me a while to work out what Simon meant). Not knowing this does seem to take away from the solve path (which is by no means simple even with the alternate reading of the rules). I can of course see the appeal of creating puzzles to solve impressively but the beauty of sudoku can also be in the simplicity. Having said that, I have full respect at the fact that you can create puzzles such as this in the first place, it’s another beautiful idea and that deduction in row 7 was simply amazing! :)

Hello Joel, Many thanks for the feedback and this suggestion. When I started setting the puzzle, I was not even certain I would use 9 arrows, so I wanted to leave the possibility open. I take your point that the addition of this little rule would not ruin the puzzle too much, but I thought it was a nice thing to discover as a solver. NB: aside from one deadly pattern, the puzzle solves without the 5 clue and it’s corresponding arrow :D.
@joelstevens56702 жыл бұрын
@@kaymennens9956 I see, it makes sense now in that context (so the rule to clarify would be something like ‘a region may contain more than one bulb or arrow’).

1:08:37 finish. I got stuck for a bit, until I caught the logic with the two 3-cell arrow in the bottom left. Simon did some convoluted logic to determine the arrow in red, but it could definitely be sorted out more easily. Start with r7c6 and r7c8. One of them is an 8, the other is a yellow 2-3-4-5. Since neither can be in blue, the blue 1 must be in column 5 (r6/7). Now look at r9c6. It is the other 2-3-4-5 that is not on the yellow arrow. Where does it go in blue? It is not r8c5 (that is on the yellow arrow), so it must be in r6c5 or r7c5, pairing up with the 1. Now look at row 7. The only place for a 7 is in green. The 6 can't go in r7c6 or r7c8 (see above), or r7c7 (a 6 in yellow below it). Therefore it must be in red, on the arrow. As for why the arrow matches up with the 9 in orange, it also has a simple explanation. Each region needs a 9 in it. The only possible way is for the 5 and 7 circles to take the 9s next to them (anything else would be too large a region). Since the 7-9 go in the same region, they would have to drop straight down from the 9 in order to pick up the whole arrow below. This wouldn't leave the 9 in column 9 with enough cells. The only other circle that can pick up the orange arrow is the 9 next to it.
@RichSmith772 жыл бұрын
He so very nearly found the problem with attempting to connect the arrow to the 7 at 38:50. He noticed a straight connection down from the 9 to the arrow didn't leave sufficient space for a region to its right. So he redrew it with a kink at 38:53. He just didn't give himself enough time to realise that kink would require 10 cells. I shouted, but to no avail. Probably because I'm four days late. 😂.

When simon got stuck at around 43 mins, what he could do to advance was to realize that the green arrow digits were different than the yellow arrow digits, 1 of them would go on R9C6 and the other with the 8 on R7. Using geometry: the digits R9C(6,8,9) would be on R(6,7,8)C5 (blue cannot take R7C6 cause 8 is orange and 2345 is yellow) and so R7C5 is 12345. Looking at row 7: 7 never goes on 3 cell arrows (also no repeats) so its on R7C4, and 6 can only go on the red arrow digits, making it a 126, plus it looks at the remaining cells making green arrow cells 134.

39:02 you're counting r7c8 for both regions. There's no way to get the 7 to the arrow *and* pick up the 9 *and* leave room for the orange region to get 9 cells. I think taking 20 seconds longer to look at that would have saved you 20 minutes of solving time haha
@RichSmith772 жыл бұрын
Yes. When he put the kink into the proposed black region, seen at 38:55, in order to give the orange region enough space, that increased the black region to 10 cells. Shame he didn't notice.

Another marathoner for me; took me just over 90 minutes (1:30:55) to make it to the end, and some of my logic was stretched a bit (though I'd like to think I stopped short of actual bifurcation), but dangit, I made it! Incredible puzzle!

@47:50, heh, that was a long work. r7c6 couldn't be blue because that would make r7c8 yellow and both blue and yellow have 8's penciled in, so you wouldn't have an 8 in Row 7.
@DontMockMySmock2 жыл бұрын
The logic around the 48 minute mark for completing the blue region is really complicated; you could've just seen that the other possible cell could only be 8 or yellow, and blue already had an 8 in it, so that one couldn't be blue.

@OlafDoschke2 жыл бұрын
Two logical tidbits up to minute 49, where you were stuck in rows 6-9. 1. Finding out whether the last cell of the blue region is in row 6 or 7: Well, the one cell in row 7 that is NOT an 8 has to be in the lower right yellow region. The other cell IS an 8 and the blue region already has an 8 in row 9. Or shorter: Cell r7c6 cannot be blue in either case: Either it is NOT 8 and therefore yellow, or it IS 8 and therefore not blue. 2. Thinking about the 6 cells of two arrows in row 7 and 8, just extend this with the 2 cell arrow in row 9 and you'll see there are 8 cells with maximum digit 7. So one double digit is enforced. Can there be just 1 double digit? The arrow circles (bulbs) sum to 8+9+9=26, which is 2 short of the triangular number of 7, which is 28. So all digits 1 to7 and one double digit, even if it is only 1 is already 29. There have to be 2 double digits: 1 and 2. That's 4 of the 8 digits, summing to 2x(1+2)=6 and the other 4 must contribute 20 and be from 3 to 7. 3 to 7 sum to 25, so the 5 is skipped to have 20. 3+4+6+7=20 and with two 1s and two 2s you have 26 in 8 digits. That will spread out as 1+2+6=9, 1+3+4=8 and 2+7=9. 2 and 7 would be in the blue region in row 9, the cell of this blue region in row 6 would be the 1, as it's already in row 9 on the right side, in row 8 and 7 on the arrows. The double 2 finds its home in r8c8 in yellow and blue has its 5 in r8c5.

Before 56: the blue region can't pick up the yellow-or-eight cell because it already has an 8. And then, where does the 7 go in row 7. Can't go in the blue region, because the 67 go in the bottom row in the blue region because the bottom row of the yellow region goes into the neck of the blue region. Much simpler.

10:50 You literally said a minute ago that by having an 9 an 8 and their corrosponding arrows in the same region the rest of the region has to add up to 11. So you can immediatly say that does not work because the single remaining cell had to add up to 11.
@jonkess27682 жыл бұрын
So the only way to link up two arrows as you correctly said would be: With 2 2 cell arrows either 2 or 3 "rest squares" which have to add up to a minimum of 11. With 1 3 cell arrow and a 2 cell arrow exactly 2 "rest squares" which add up to a minimum of 11.

I got a different (non)solution: in the gray area, instead of 91862 i found 96812 and below that, the numbers in the yellow area are swapped: instead of 61/8 in my solution there are numbers 18/6. So it seems there are at least 2 solutions, which is kind of sad. edit: sad that i didn't see my mistake - absolutely lovely puzzle!
@RichSmith772 жыл бұрын
If I've followed your changes correctly (and I think you must have meant 96182 in grey, otherwise you have two 8s in c7), then you must also have swapped 8 and 6 in c4 (otherwise 8s and 6s repeat in rows 3 and 4). But the problem with this is that you end up with two 6s in the top blue region and two 8s in the purple region. The check function doesn't check the created irregular regions, so it still says "Yey! Looks good to me". There is only one correct solution, the one Simon found.

Do the rules imply each region must contain exactly one arrow or is that do be deduced by the solver?
@RichSmith772 жыл бұрын
It appears it should be deduced. I mistakenly assumed there would be one arrow per region. I got completely stuck after half an hour. Watched Simon's solve for a hint, only for Simon to immediately consider the possibility of two arrows in a region, which I'd ignored. So I restarted without this assumption. 15 minutes later I reached just about the same position as before, and was still stuck. 😂.

I didn't get, why there couldn't be two repeated digits. E.g. 126 + 125 in the red/green arrows, puting a blue one beside the 9, a blue 2 in the bottom row, a yellow 1&3 in the bottom right and a yellow 4 in R8C8, a blue 3 in R8, etc
@RichSmith772 жыл бұрын
You would have nowhere to put a 2 in yellow. Any digit repeated on the red/green arrows could only go in row 9 in yellow. That rules it out of rows 789 in blue. There's only one blue cell available above those three rows. Hence can only be one repeated digit, as only one place any such digit could go in blue.

When trying to see if a circle can reach an arrow, you do realise you can stop counting as soon as you reach 9 don't you? Continuing to count up to 12 gives you no additional insight. In many cases, you don't even need to count - most of us can easily identify up to 5 things without counting them. In a puzzle like this, you're generally trying to join the closest of any existing cells in a region to the furthest arrow cell. You know how many cells are already in the region, and you just need the taxicab distance to the furthest arrow cell, and the horizontal and vertical components are usually easy to enumerate without counting. As with every chaos puzzle I've watched you solve, you spent an inordinate amount of time considering arrangements that were clearly impossible, whether because they would require much too many cells, they'd require a cell that contains only options which are already in the region, or they would isolate cells. It seems to be because you're incapable of considering more than one rule at a time, unless you consciously decide to look for constraints imposed by multiple rules. I've noticed this trait in many multi-rule puzzles (e.g. the recent equal-sum/renban puzzle). I suspect it also explains why you place so many inappropriate pencil-marks. You consider a column and put in the column options, even though digits in the rows and/or boxes already resolve them. If you really are incapable, might I suggest that you develop techniques that avoid the problem? For instance, instead of highlighting the last three cells in a column and filling them with 368, highlight the cells, then deselect any which see a 3 by considering each of the rules in turn. Only after doing this do you press 3. Repeat for 6 and 8, and you've avoided the problem. Sure, it takes a few seconds longer, but it can save you several minutes in the long run, because you're not looking at a grid full of impossible options, which is frequently the cause of you getting stuck.
