"Octopus Rules Apply"!!!

[Music] hello and welcome to Wednesday's edition of cracking the cryptic where yes I'm on my laptop today it's probably going to be the only day that I'm on my laptop um many of you have noticed that I've been on a short break uh and pre-recorded the last few videos uh on the channel and so I I apologize for that I apologize if I've missed your birthday shout outs don't worry I am intending to catch them all up um over the coming days there are a number that I have been remiss about um but I I wanted to well I I need to do a video today obviously we don't want to miss out we we've done a video we've done two videos a day for every single day since the start of the first pandemic so I don't want to break that streak um but also today is the birthday of a Constructor I really admire greatly The pedling Pianist um in my mind is one of those Constructors who just H have you know very unusual brains in the best way um so I'm thinking of people like Marty seers um D Leia uh Jay D just really unique mind and um this puzzle has been recommended to us as a um a birthday present for the pedaling pianist whose birthday it is today it's called killer octopus um and I I had a quick look at the rules before I turned on the webcam and was amused to read that octopus rules apply I was thinking I don't know what are octopus rules but luckily it does explain so I'm going to have a go at this for you I will be in I I'm in Holiday brain mode so I might be particularly Ed less today I apologize if that's the case um and I'm just trying to think whether I've got anything to tell you about before we kick off uh we are we're inching up towards 600,000 subscribers where we've got uh a special uh pack of puzzles uh prepared for you by some of the Great and the good of the soku community so if you're not subscribed and you enjoy the channel and you want a free pack of amazing puzzles consider subscribing it is of course free to subscribe to YouTube channels um um and the other thing I wanted to mention actually was a couple of people who WR written to me with particularly um uh moving emails recently uh Tom who lost his father uh on Monday Tom uh obviously our sincere condolences and thank you for taking the time to write write to us even in such heartbreaking circumstances um and also to Ivon who wrote to me last night um and ion you know what was in your email thank you thank you for sharing it with us um it does mean an awful lot to me uh and yeah with that let's turn our attention to happy things and having a look at killer octopus and let's see what birthday celebrating and hopefully chocolate cake eating the peddling pianist has in store for us these are the rules we've got normal sedok rules apply that means we've got to put digits one to nine once each in every Row in every in every column you could I'm not used to this mouse and every 3x3 box there's not much in this grid actually is there uh digits in a cage must sum to the given total so those three digits sum to 11 these to 14 these to 14 those to five that's all we've got there and then it says octopus rule Supply I love the way it says IE as if you know I probably should have known what octus rules are uh but I draw four lines that must not cross or overlap anywhere except row five column 5 where they all intersect so okay so there's four four lines going through row five column 5 uh the four lines must have 180° rotational symmetry about Row 5. 5 so that means let's go to the pen tool um yeah this should work shouldn't it so if I do so if I draw that uh no hang on I've gone too far so what we're saying is that the line that we draw through this midpoint here has to be rotationally symmetric so if that one kinked upwards that one has to Kink downwards in order to maintain the 180 degree rotational symmetry you can see if we if we swung this line 180 Dees with the center of the grid as the Pivot Point the line would look identical so it is 180 de symmetrical and that seems to be a condition sorry about the sound quality today by the way if it's not up to Snuff um my my laptop is meant to be decent but uh Mark thought I did a crossword video while I was away and Mark thought the sound was a bit uh worse than usual it's there's nothing I can do about it so my apologies if so um now what next uh these four lines visit exactly two cells on the edge of the grid hang on is that the four lines or each line which are the beginning and the end of the line right so I think the way that's meant to work grammatically is that each line has to visit two cells in the Edge Edge of the grid and those will be the beginning and the end uh of a line so let's draw so let's imagine that oopsie that's a line I think that might be possible something like that and then you can see that this line would yeah so that would be that would be the start and the end of this line because that's basically what it says um now we don't know of course what the line might have done before it gets to the edge of the grid so we could have some crazy lines something like that and then what's the equivalent of that it's going to be something like have I messed this up or is that is that it might be that I don't know something like that looks about right um let's restart the puzzle um there's one more condition for the line oh right all the lines are the same length I.E in number of cells passed through so uh so that would be a length nine line if if it was a very simple line like that and that would mean that all the other three lines had to be a length length nine line now the four lines that we draw are same difference lines I.E pairs of adjacent digits on a line must all have the same difference although this difference May be different for different lines so let's let's draw go back to my example line so let's say that was a line and let's say that this was a nine and let's say that this was a six then 9 - 6 is three and that means every cell on this line would have to have a different so I'd actually break the line sorry you can tell immediately my brain doesn't work um yeah this line couldn't exist because the line would go nine six which is a difference of three and now this can't be nine anymore these these two digits here have to have a difference of three so we have to go six three but then this can't be zero and it can't be six again can it because that's going to break the rules of sidoku so goodness okay so there's probably going to have to be some crookedness to the lines is what we're establishing anyway do have a go the way to play is to click the link under the video as usual now I get to let's get cracking um now I think what we're being told abono because I've got to draw four lines and each line has to visit the edge of the grid the lines can't be of length one can they they've got to be of some length that's greater than one and once the line is of length greater than one and it has a Center in Row 5 column 5 and and once the line cannot intersect or cross itself then what that means I think is that the the lines must do something like this they're going to have to all because they because they're not allowed to touch each other it says not cross or overlap anywhere except Row 5 column 5 where they all intersect so the lines all pass through row five colum 5 once that once this blue line passes through it's rotational rotationally simpar so once the line once this line once this line goes to Row 5 column 5 it's rotational rotationally Al counterpart must also be on the blue line so each line is going to basically have to start going straight through Row 5 column 5 now what that is making me want to do is to write five into row five column 5 um because now what we're saying is that somehow or other yeah I think I think my instinct there is right although how I explain this is perhaps less clear so I can see that if I write five into the middle I can deal with the extreme digits what do I mean by the extreme digits well I know that there must be a nine somewhere and there must be a one somewhere in the panoply of digits that live in in box five of the sodoku so I mean imagine I put three in the middle for example what line can I now put nine on I can't put nine anywhere because if I put nine on the pink Line This digit well this is a difference of six and we can't put minus three here so the only digit that works between three and that's three and nine apart is is sort of is nine we'd have to have another nine and that can't be true and the same is going to work if if I put eight here then I've got the problem with where where where where does one go wherever I put one that's a difference of seven the other side of the line couldn't be filled so I think that that is five and what that will allow me to do is to deal with one and nine because one of these lines is now going to be a one opposite a nine with a difference of four and then I can deal with eight by having eight opposite two I can deal with seven by having seven opposite three and I can deal with four and six by having them opposite each other so I think this is what we're being told is the start of the puzzle although goodness only knows you're going to have to use the hang on let me just go back to the rules I just want to check whether there's anything else I need I need to consider about the oh yeah the lines have to get to the edge they all have to be the same length so they can't stop here they've got to go much further and they all have yeah okay and E okay so the one thing that we have learned from this is that each line does have a different same it has a different same difference because the the the line that has 951 has a difference of four the line that has 852 has a difference of three the 753 line has a difference of two and the 654 line has a difference of one so the four lines all have different same differences now what does this mean uh well one thing one thing it means is well however the lines grow right okay I can see something here although I'm now questioning is not I was just wondering whether this was about the fistell ring for a moment which is such a strange thing to think about but I don't I just want to give that a moment's thought H I don't know it might be you know it might be because the thing I have noticed is that the line the the the line that has one and nine on it let's just say it's this one just just for the sake of exposition let's say that's a nine and that's a one now and let's extend the line oh hang on let's extend it in the right let's say extends like that then those two digits that one and that one we actually know what they are because they because this line is a four difference line and we've sort of Hit the extreme digits which are the one and the nine so so we're always going to have to have fives opposite each other on the one five on the 951 line but the same is true I think on the 852 line because the 852 line has a difference of three and so obviously you can't let's let's do that let's do that line as well let's say uh this one does that and let's say that this is the eight line you can see we can't the only difference of three sodoku digit we can't write minus one here is five again so I think what we're being told is that there are four fives on the fistell ring which is why I was thinking about the fistell ring um that's that I think is correct isn't it because any extension of any of these lines is going to be onto the fistell ring this collection digits there and and is and on those two lines the ones that have the nine and the one and the two and the eight on they are going to require a five to be which means that the a five on both sides of the of the sort of rotation symmetrical line so that means there are four fives in the fistel ring and that means that you cannot extend those particular lines into those positions because if you do write five in the corner of the F bell ring now you can't put four fives in this collection of digits and uh I don't know if that's clear um I I mean it's such a lud a way to approach the puzzle but it's just you know it's something that one one gets used to if one's used to Counting digits in the fist of of our ring which I most certainly are any digit you put in the corner of the Ring can only appear maximum of three times in the ring because if this is a five we could have a five in one of these squares and we could have a five in one of these squares so we could put five oh actually five in the middle we can't do that could put five there and five there say but we couldn't get a fourth five in the ring because sodoku would prevent it so I think what we're meant to appreciate well this is interesting isn't it because what that means is there is a five in the 11 C there is a five there there's a five there oh hang on I've got to deal with the middle digit right and none of these can be five by Dent of the middle digit so the five in the 11 cage means the other two digits in the 11 Cage have to add up to six without using five again so they have to be two four so this is beautiful this is absolutely beautiful so that means that we've got a 245 I can't actually see that I'm going to just delete that for I I must have some option maybe it's um large digits is that it is it large digits so if I do that I've turned large digits on oh yeah that's better there we go now I can see the cage total right so has that helped us the answer is I don't know well I can see I can see several things but I don't know which one of them to talk about the the first thing to say is that actually what I was about to say is wrong I'm not going to say that now um okay where does the green line go for its next digit oh good I've just seen something obvious ah bother bother right I'd not thought about this there's parity there's a parity Point here um right I I got this by thinking about the green line and thinking thinking how it how it had to extend but but the point here is much more General than that um let's let's extend the purple line there and let's think about the parity of this Square which is something I've not thought about could this ever be even 2 4 6 or eight and the answer is no because of the same difference quality we have to have Vis A the five imagine this was six what number do we put in here that has the same difference between five as it does with this six well it would have to be the digit midway between five and six which is 5 and a half which is we can't write in soku if this was eight this would have to be six and a half it doesn't work so actually there's more much more General Point uh we have we got to count the odd digits on the fist Mel ring or something I've got I've got eight line tips that have to extend from box five into the fist ofl ring so eight of the 16 digits of the Fist oh no no actually this is so eight of the 16 digits will be forced to be odd in this my goodness what was that noise sorry there drilling sound coming from some um okay well let's go back to the green line tip then where does that go because that can't go into an even digit and the 11 C has two even digits in it it must hit the five that lives in in the 11 cage for its next cell it can't overlap with the blue or the purple or the pink if you prefer it can't overlap with those lines so this green thing either goes like this or oh hang on this is okay I'm so I am my brain is being appalling this is why it's called octopus uh because there are eight legs the octop oh this is gorgeous this is gorgeous right yeah this this this is the octopus is body the five in the middle F the circle it has eight legs coming out there oh dear right okay that's good to know that's good to know slow brain sment today um right okay well I'm going to go back to a different thought I had which is if we look at the arrangement of fives in these squares you can see there's always if the five if this is a five then that's a five by soku and if this is a five then that's a five by soku there's sort of an X in fives in boxes four and six but what that's going to mean is that one of these squares at the top of a 14 cage is definitely five and this is going to get very difficult to pencil Mar because that means that definitely one of those squares is a nine definitely just see something else actually but the other the coroller that is Imagine The fives would dispose like this so this is a 59 pair then this is a five so this can't be a 59 pair so this would have to be a 68 pair but six and eight are even and that's going to restrict like the pink line it's very hard to do this because we don't know how to yeah we we don't know how to oh my goodness another noise it sounds like the drain gurgling over there um we yeah we don't know which way around the octopus is going to sort of position itself so if the octopus did that then this would be a 68 pair which would mean that oh right okay oh wow okay I can now see it right this is beautiful this is a beautiful puzzle right okay let me try and explain what I've just seen so what I've Just Seen is is there is right the green line I'm now going to claim is the only line in the puzzle that is able to go into any of those three squares and that is because the green Lin's extension pens just dropped on the floor the green Lin's extension has to be into the 11 cage and it has to be into the five of the 11 cage because of ity and therefore say it was there the green line would look like that for its first few cells now could any line could could the Blue Line in this in this instance therefore come into these two squares well no because to do so it would have to take an even digit from the 11 cage which is not allowed so the so the only the only line that can take any of those squares there so maybe I can almost use the green color is the green line that green line can go into exactly one of these squares and exactly one of these squares but no other line can breach can can do that now depending on which way around the fives go in rows four and six yeah the octopus is going to have it like it's going to have droopy legs on one side and high legs on the other because on one side this four this 14 cage is a 68 pair don't know which side but there are three line segments either on this side or this side that have to get out of the central box so imagine this was a 68 pair let's make that a six so if that's a 68 pair that means that it is off it's out of bounds for any of these line segments all of which have to extend because we have to get them to the edge of the grid so they would have to go into those three cells and they would have to be in order wouldn't they because they can't overlap with one another so this blue one would have to go there the red one would have to go there and the pink one would have to go there now if on the other hand this is the 68 pair and we know one of these is the 68 pair then these have to um have to extend so then then the blue one would go there the red one would go there so the red line the red line always has the five on it ah right hang on I've had another thought now this is this puzzle is beautiful it's absolutely bizarre but beautiful um right so we know that the line we we know this line definitely has a five um in one of these two positions therefore we know well well we now know I believe that this line is either the 1 n line or the 28 line because we are capped out on fives in the fist of ring there can't be more than four fives in the fist ofl ring and we know that there must be four fives on the 1 n and the 28 lines so there are no fives on the 3 S and the four six lines now that means that means that this green line and we still don't know where it goes but it definitely is either 1 n or 28 and I might be about to conclude the same for the red line I'm just going to think a bit harder about that because because we know either those three or those three are the exact order of how the pink red and blue line extends it's always the it's always the red line that picks up this square or this Square so the red line that must be 1 2 8 and N which means these other lines are 37 4 and six now what on Earth does that mean me so that means let me just think about this so if we go this way if this is out of bounds that means so this is a red five this is a Luke Skywalker xwing fighter this is red five standing by this is pink but the but the symmetrical counterpart of that is there which is a nine yeah so what we're actually being told is that this line the pink line oh no are we actually I might be wrong no is it just in that yeah no it depends oh bobbins no I'm not sure what I was about to say is right at all how on Earth it must be it must be the five cage down here that's going to determine how the octopus in the end droops because the octopus is either going to be happy on this side and its legs are going to be up in the air and then down on this side or the octopus is going to have high legs up here and be down on this side but I don't know whether it's this line or this line that provide one of these lines is going to give rise to a nine in one of these two squares and therefore that is going to be on the 37 line because um well yeah what we're going have on one oh this that does that mean one of those is a seven maybe it does yeah because this is very hard to explain but imagine the the octopus has high imagine this is a 68 pair then we know that the octopus takes these three squares in the order blue red pink okay so we know that blue the counterpart for blue blue has to be here and this is a 59 pair so this is n and therefore this is seven so one of those is definitely seven which means neither of these is seven which means one of these is opposite three so neither of these is three and then the okay so the other line the 46 line which could be blue or pink at this point sort of looks like a heartbeat monitor I think so if it was the pink line it would look like this with these being this being four or six and this being four or six and we can't go back to five here right so these squares would be well the this is interesting so these two squares here are 37 but I don't know what line they're on because we could absolutely be in a situation where in where we're in that world and it's the blue line that's doing the heartbeat monitor so I don't know how to do that I I don't know how to um I don't know they put the dishwasher on or something I don't understand why there's so much gurgling um yeah so whichever whichever is the 4 six line which could be blue or could be pink is going to bounce here into these squares where so say this say it was the pink line and we this is four or six and then the next digit is here you can see if this went five four it can't go back to five so it would have to go to three and if it weren't five six it can't go back to five so it would have to go to seven so these two squares are a 3 S pair I think this is going to do nothing I'm afraid one of these is definitely a three and that's going to be on a line yeah that's going to be on a line whose next digit is in one of those two squares and is two right and it's twoo different from three but can't be five again because there's definitely fives in either of these squares so so one of these two squares is a one that doesn't do anything either how on Earth is this going to get disambiguated I don't understand how we can be I don't understand how this five cage is meant to do enough work here Ian it's actually fairly incredible that you can get to this point just with three cages and this weird rule okay where's Five in box nine that is a legitimate question because I know there's a five in one of those I know there's a five in one of those and I know you can't put five in a five cage so five is in one of those squares five is in one of those two squares yeah so but I mean this is just the coroller of the pist bell ring we're going to get fives all over the place in the 2 by tws in the corners it's just on this side it's slightly more restricted yeah okay but the yeah okay hang on hang on but the right uh I had thought of this I haven't thought of this but I have now right it's I don't I haven't got my head around this but it's something to do with extending it's the green and the red lines because the green and the red lines as they extend further through the grid they always have fives on them every other cell so let's imagine we're looking at a line that goes 159 the next digit which is because it's a difference of four line the next digit is definitely five on that line then what's the next digit it has to be a difference of four from five so it has to be one or nine but then the next digit is going to be five again and it's the same I think on the 28 line because the 28 lines let's say we've got a line goes 2 58 the next digit will be five it has to be three different the next digit can be two or eight but then the digit after that is still five again right right this is big because what this means is that well what this means is that somehow I've got to get I've got to join up I think I can see I think I can I can see what I'm being asked to do I don't no idea how I'm going to explain it but I think if we now imagine we've got we've got these two lines which are this line and this line and we have to get both of those lines to the edge of the grid somehow so the most efficient way we do that would be a straight line which these can't be straight lines but let's imagine that they are dead straight each line would be nine cells long and that line let's imagine this was only nine cells long how many fives would it have on it and the answer is five well yeah it's five fives Al together and the same is true with the green line the green line could be a minimum in order to get two cells on the perimeter it could be a minimum of nine cells long in fact yeah I mean it's it's confusing because I'm drawing it vertically and obviously you can't put five Fs in column five but just in terms of the way that the parity shifts along the line you're going to have a let's say that this was the 1 nine line then we know that there's a five next don't we we've got to get to the edge of the grid we're told that so let's try and do that efficiently this would not if this was a five this would not be this would be a one or a nine and then we get to the edge of the grid and we need another five so actually what we're being told is yeah I think we're also now capping out the possible length of the lines in the puzzle because if the one if the one n line or the 289 were long were say 11 cells long there would have to be even more fives on them than there are in the puzzle there are only nine fives in this puzzle and we know that those nine fives now have to be five of them are on the red line and five of them are on the green line and the way we can achieve that is because one of them is shared but what I was thinking is how do I connect the five that lives in box nine which is in one of these two squares to another five that could be in this grid within two cells of it and we've pinpointed all the positions of five so this is this is so beautiful this is so beautiful can you see what's going to happen so the positions of possible fives in this puzzle are exactly this map I'm going to draw it everything those are the possible fives for every five in the puzzle H well let's let's be fair that one as well that one in the middle so a five here has to connect within two cells well so this can't be a five in the bottom right there's no way you can get get it within two cells to a five to another five it would have to be a five that's outside its own box so that is not a five this is a five definitely and within two cells I can't get to that one I've got to get to that one with a diagonal movement now I well okay so what I can see this is now doing is it's structuring it's structuring the octopus the octopus now is Happy on this side of the grid um because this because this is a five that means this is a five and we know that this is the red line don't we that's joining this so the Red Line is now doing this and how does the red line get to this Square which it must now do must provide the way that we get to this five in the Grid it's got to do that and there it's got to do that that's pinpointing another five up here so oh and that g me five here so okay this is just playing all the fives in the grid May well maybe not does that mean how do we get to this five is it via that one because that's going to be great as well because that's going to give me the structure of the green line which I wasn't expecting to get yeah because now now if we delete everything that's definitely not five you can delete all the color from those squares get rid of The Vibes and corners of those squares so now how do you connect to this it must be by that one must be connected to that one so we get to this position we can delete the Green from here we can attach this to this attach this to this that the only way of getting it again is diagonally because you got to get to it within two squares which means okay which means that is also maybe I could have done it by thinking about the top of the grid but I didn't obiously looking at the bottom of the grid so we' got a sort of pin wheel thing going on now but but much more importantly and now know this is a nine this is 68 because it can't include a five and now the octopus has to stay away from these even digits so the pink line goes like that and down to be rotationally symmetrical the blue line goes there and there and now what's the difference we need to have the same difference on the blue line so that's seven so this is three this is one this is not one now this is not three anymore I would absolutely love it if this now collapses that would make me very happy um let's still I mean how can there possibly be enough information on this now to this to finish um probably what we're meant to do is to look at the midpoints of the of the lines that we do understand which are those now we know those digits also 1 28 and N don't we now that one can't be one that one can't be nine that one can't be nine that one can't be one uh that one can't be two actually I've just noticed there a two four pair here so this is eight or nine it doesn't it doesn't have any effect on this does it this is bizarre absolutely bizarre um and [Music] how how are we going to oh I see right okay so look at the Blue Line this line here so the next cell on this line has to be twoo different from nine so it's a seven Well it can't go back into this column then and it can't go there oh it no it go there it would cross a line so it has to be there doesn't it I think that feels like it must be true which means that one so that one goes up there and that's a differ two so that's a three and now the ne oh oh no I've broke no I see no I was suddenly thinking well now I need a five but I don't because I can go back up to nine again so let's go back down here and say what's the next digit now there's a hammering no um well the next digit has to be two different from seven and can't be five because all the fives are on on the on the green and the red lines so we need a we need a nine now now the nine can't be in box nine it's already a nine there it can't be here so it's either there or there I think one of those two squares is a nine which means that's not a nine and the same's going to be true on this side where but with one uh okay which we also don't really understand then so there's a one in one of those this is not a one soku okay so that's seven now this is three so that's four that's six that's seven that's oh this is just stunning this is St com okay this is now not eight right so I need two four and nine I'm just going to pencil Mark column three if you don't mind know it's against my better nature but um okay right so how does this finish from here we could uh have I this the middle done it would be very oh maybe the two pairs done no there's not some weird sidoku poker is there probably is actually let's just try sidoku for a moment I mean it would be astonishing and outrageous if pedaling pis does include any soku in his sedu puzzle I feel like I must know that is two or nine so if that's two obviously this digit would have to be also two because it couldn't be eight so if that's two that's two and that would be eight and that would be two I don't know if there's a problem with that I can't see it if there is um six can't go in the five cage down here so six is either there or there so six is in one of two places in box eight okay how strange is this got loads of odd digits down this column um three is in one of those squares sorry if there's there's a load of drain noise in the background now seven is in there's a lot of symmetry about things okay maybe uh it's either this cage or the extension of the pink line line I don't see how to use that cage I'm going to think about the extension of the pink line so the pink line now from this direction the next digit is either it's got to be one different from three so it's either two or four there's I well there's a tiny restriction because you can't put four in that row but there's no restriction on two I don't think this side the extension can't go to eight so the extension on this side does go to six which is moderately interesting perhaps okay well yeah okay so there is a six in one of those squares is what we're being told I think this must be one different from seven and it can't be oh hang on no why couldn't ah I hadn't thought of this why what what is the problem yeah okay so I misspoke slightly earlier I was thinking about the impossibility of having an even digit on the line in the fisl ring and that was that was correct if that digit was the third third digit on the line I if it was two away from the center but here what we could do is that couldn't we had thought of that if you do that this could be eight probably that would then make this a two ah no ah hang on there might be a problem with that which is another thing I hadn't thought of and that thing oh can we do that I'm not sure I'm wondering if now we can conclude that the length of line we're looking for in this puzzle is nine from from the green and the red lines because I'm not sure we can do it though because imagine that I think the the only way the green and the red lines can grow again is if they grow exactly one more cell on each side because if they grow two more cells on each side they'd need another five and we' run out of fives all together oh hang on no there's something in the rules that says once you get to the edge Ah that's it right we've got to the edge and the rules say that once we visit the edge those two cells on the edge on a line are the end of the line so so the length right so that means that we have finished the green and the red line at length nine which means that the other lines are all length nine as well and that means I can't do what I was just envisaging here which is to dip from the pink line to the eight because the next digit would need to get to the edge of the grid because this is only a length length 99 every everything is the same length and we need to get to the edge so I do have to take a six here and that six must be in one of those squares definitely uh which means that on this side there's a two there's a two or a four that's sort of affecting that but not in a way that's definitive it would be much more useful if it wasn't a two and a four but hang on if that's a six what's the next digit oh I see oh this is go gorgeous right okay so now the extension of the pink line can't be to there because if it was that would be a six the next cell would be one of these but would have to be a five or a seven which are not not allowed so this is the only extension that we can do at the pink line good grief so that means that the extension of this line is to here to be symmetrical but we don't know probably what that is it's two or four and it's having some impact with this sort of a virtual two four pair now between these two these three squares because if that's a two this has to be a 1 14 pair if this is a four this has to be a two three pair um but let's come back to this because the final piece of the jigsaw for the the pink line we've only got one more cell left to take and we know that this it can't be in four because five and seven have already disappeared so this this has to be a seven I think because it can't be a five so that has to be the final digit which actually gives me another seven there by sedu but that's the final digit of the pink line which means the final digit of the other line is here um and now let's just let's just see if I can do any better with the sevens I was just doing no I don't think I can I don't see how to okay and this digit now is interesting isn't it because if wow wow okay this can't be a four I don't think for the mo this is beautiful this is absolutely ridiculous pedaling pist you are a genius actually you are a genius look if that's four what do I put into that square and the answer is not five because five's disappeared I need a digit that's consecutive with four so I have to put three so we'd have to go four three and now how do I fill the five cage two three doesn't work and one four doesn't work so you can't do that so in fact this is two now this is a one4 pair that's not one that in fact this is become an eight now oh that's going to do it that's going to do it because now I know what red line is um but what's this oh I see that's three again because that's got to be basically be from the same five pair we can't put one here because it would break the five thing so that's got to be three and be one different oh this is this is Sublime it's ridiculous this is a ridiculous puzzle right but now okay so now let's uh but and it's also this two is giving us this as a one or a nine which means that we now know the green line is well the green line is the one nine one so that's a one uh that's now a nine this is 208 this is 208 this is eight because it can't be nine these squares are know they're 36 and N which means these are a 39 pair look so that's got to oh I can actually do this that's six that's three that's nine nine is in one of these two squares those two squares at the bottom of the grid are something two and two and six yeah okay so we can do that six in the cor and no s for me that's now four or a nine that's a four by soku so that must be two at the top these squares are 4 six9 she uh yeah that's done that gives us six in the corner well nearly done anyway we get a 49 pair um I haven't the other thing I haven't done I just noticed I haven't extended the blue line all the way so the Blue Line oh yeah we worked out that needed a nine next at the bottom didn't it which now I can see has to be here so the blue line and that means that's a one it's the same logic actually so that's the extension of the blue line and all all lines are now finished and all all we've got to do I say all we've got to do this could trip me up is soku that's a four so that's a four that's a nine that's an eight um two three four need six seven and nine this is a naked single that's a seven so that's a seven this is a six this is a nine that's a nine that's a one that's got to be a two now uh this is a 14 pair somehow isn't resolved so this has got to be a 28 pair that is resolved two goes there eight goes there those squares there three and that's resolved seven and three so these squares now are 689 which might not be resolved partially resolved oh no the nine we can do nine goes there six and eight BS okay um what about this Row 1 three and four so this is one or three this is 1 three or four 1 two three and eight into here eight is in one of those squares oh come on Simon this must be finished isn't it [Music] um it probably is that's not nine anymore let's try 1 two 68 what about that square that's just one or two in fact this Row one two and four that's two or four there's a two four pair now and that's one or h no it's not that's one that's going to do it so that's two that's four that's four that's two that's two that's eight hopefully we're now on the home stretch we need one two and three into this column so that's one or three that's become aoku that's got to be a two it's got to be a nine that's a three that's a one that's a one that's a four these two squares are three oh we could have a three in the corner it's possible there is the possibility of a three in the corner down here I think four goes here one goes here one goes here so six goes here six goes here eight goes here in this column uh no we're not going to get it that's going to be a three so that's a seven that's a three we're going to get an eight in the corner and we going to get an eight there what a brilliant puzzle that is is it right yes um solved the puzzle 53 minutes solve counter four 14 in 71 days what I thought this was a new puzzle 71 that's two month it's over two months old good grief that's Sensational that is a sensationally good puzzle killer octopus indeed Take a Bow the pedaling Pieris what a fabulous fabulous construction ridiculous Miracle esque because there's not much in the grid and yet all the logic is just tight enough that you can find a way to the end or at least I could even with my holiday brain in um so thank you for watching really appreciate it thank you for sticking with the poor audio it was bad um and um yeah uh it's nice to be back and we'll be back later with another addition of cracking the cryptic [Music]
