Don't Get Left Out: Puzzle FOMO

[Music] hello and welcome to wednesday's edition of cracking the cryptic and a big thanks to john delphin uh for his take on mozart's sonata number 16 in the intro today some of you may be very familiar with john's name he is a very famous person in the history of american crosswords john has won the american crossword uh puzzle competition no less than seven times absolutely brilliant um anyway today's puzzle is by fritz dis another by fritz dis he's becoming an absolute regular on the channel such of the quality as of of his offerings and this one i think has a 98 approval rating on logic masters germany and it's been specially recommended to us by our discord server so it ought to be an absolute treat it's called left out um and as i was setting up the webcam i was wondering why it's called left out i can't see anything um you know if i highlight the cages you can see that this one looks a bit like a cue i'm not seeing why these are does that look like anything redolent of the phrase left out i'm not sure anyway we shall discover in the soul whether anything's going on um now a quick spoiler before i get on to the next item if you have not solved um the puzzle i covered in yesterday's bonus video which was a solve of dave gorman's most recent cryptic crossword then i'm about to put the final solution to that puzzle on the screen so look away now cover your ears i want to show you this because i think this is absolutely startling and it will appeal to many of you who watched the game show only connect because dave had put a hidden theme in the puzzle which was only connect so if you look carefully at this grid you can see only connect their two answers and you can see all the categories you can select in the game only connect there's lion uh two reeds twisted flax water eye of horus hornered viper so they're all there all six of the categories but the thing i absolutely love is this row here it might not let me do this oh it does look there you go um and this row here and if you stare carefully at the sort of white cells here you can see it might look like gibberish but if you're a fan of the program you will be very familiar with the missing vowels round and dave has hidden that with its missing vowels in the grid here in these uh unchecked letters absolutely wonderful stuff um so that got me very excited and i thought some of you might enjoy that so i'm sharing um now anything else i want to mention before we kick off with a puzzle i just have a look at what's going on on patreon i really do think it is um startlingly good value it's two bucks a month to join us on patreon there are i think four thousand of you have joined us now and um we've got yesterday we released mark's attempt to solve six times crosswords in an average time of six minutes we've got the wonders of the world sudoku hunt which is still getting answers in by the hour and we've got scott strauss video on how to solve his own sudoku challenge um and that's that's that's all stuff that we've released very recently and there's more stuff coming as well so watch this space um now let's get to the rules of fritz this is puzzle why is that cell highlighted i don't know we have got normal sudoku rules apply good digits cannot repeat within a cage ah now i've got a note here there are five nine cell cages in the grid which were colored in frits this is original version oh they're not colored here um a nine cell cage must uh as no digits can repeat contain all the digits from one through nine once each yes okay so i highlighted these before i think i was meant to keep them highlighted probably let's highlight them in some different colors we can do those this one could be purple that one can be green there we go so you can see that these cages two three four yeah they are they're all nine cells large which means these effectively form extra regions in the sudoku they work a bit like this box this box has to contain the nine digits from one to nine once each well because you can't repeat a digit in the nine cell cage each of these cages also has to contain the digits one to nine once each now i imagine i've been given a white grid because they think i'm going to need to highlight so i'm going to trust them and put them like that now what else we've got digits along an arrow must sum to the digit in the connected circle uh digits may repeat along an arrow if allowed by the other rules so standard arrow rules in other words which means those two squares for example whatever we make this domino add up to you put it in the circle and you can repeat digits along arrows that doesn't look very easy to do this one might be a yeah okay this is i think the only place where a digit could repeat along an arrow and in fact looking at that it looks like only those two squares could repeat but that's almost doing some logic from the puzzle but so if it'd be absolutely fine for example those two squares could be two and then whatever those two squares let's make this one and three you can see these arrows together now add up to eight so you'd put eight in the circle and that would be a perfectly valid arrow in this puzzle so do have a go the way to play is to click the link under the video as usual now i get to play let's get cracking um now actually it's a bit like yesterday isn't it we've got these huge cages and what i think we're going to have to find because i mean if we look around the grid as usual there are no given digits there's no there's no help here um there's going to be weak cells i think in some of these cages where digits are going to repeat in interesting places so my job's going to be to find yeah i mean there's some there things that are immediately interesting two things to me are interesting about this cage the first thing is that those three digits whatever is in those three cells there where can they go in box nine box nine box seven can't count where do these three squares go in box seven well they can't go in those squares or they'd repeat in the cage so they have to go in those three squares there so so these squares and these squares are the same but you can go further than that because this square actually that must repeat exactly in this position because it can't repeat in the cage and it can't repeat in the column so that square and that square are mirrored so there's already some coloring opportunities and we don't pass those up so these two squares are the same these red squares must map onto the start of this arrow now can we do anything with that the answer is no i'm not sure i can i mean i know one of these is blue but i don't think i know i can use that to detect its quantum um [Music] this one let's have a look at this one then this one doesn't look as good to me at first blush maybe i'm missing something no i don't think that one's very helpful at all to be honest this one this is the backwards q yeah well there's there's a similar stripey thing going on here in this one so whatever goes in those squares can't now repeat in the in the queue shape so we'd have to go in those three squares so these three squares mapped to these three squares mapped to those three squares and that's certainly worth um yeah okay and that's that's just going to repeat everywhere in this these three columns isn't it so what do the where do those three squares go in this box well these three squares cannot be green so they don't go there by sudoku they don't go there so they must go there so these so there's there's those three stripes we can draw let's make those orange and therefore the corollary of that is that those three must form their own region now i'm going to run out of colors soon this rate right so those we've now got sort of funny uh arrangement that looks like a very unpleasant ice cream flavor down the right hand columns of the grid now let's just study this for a second because there should be something we can do with this we can um maybe i've got to look at this arrow actually well i can say something about the circle from the arrow because if we look carefully this square this square and this square are all in the same cage so the minimum i could put into those three squares would be one two and three they all have to be different because they're in the same cage so these three have to add up to at least six this has to be positive so it's got to be at least one so that means seven is the minimum we can put into the circle yeah and going back to what we did in the example those two squares have to be the same how do we know they're the same well what would happen if these we know these three squares are different what would happen if this one was a fourth a fourth digit a different digit to these three well then the minimum we could make the four cells add up to would be one two three and four which is ten which is too many we can't put ten in this square so this square is the only opportunity for a repeated digit and it it can't be the same as the it can't be different ah i'm getting tongue tied today this square and this square are the only opportunities for different digits because obviously whatever we put in there cannot be here and cannot be here so those two squares are the same and that's going to ruin my lovely coloring if i color those another different color i know what i'll do i'll i'll label them because we can't make these as high as double four even if you try double four and those two squares how are we going to make fill those squares to keep this down to a single digit number we can't so these squares have to be i think they can be three double three with a one two pair would make this nine that would work so these are the same and whatever goes in here obviously goes in here and whatever goes in here has to get one of those and one of those if that was double one now you could still have some relatively high digits in the other places on that arrow so this should we look at this cage um there must be something going on with this cage it takes up so much real estate in row four uh yeah this is lovely right okay now we can use our funny pattern on the right because this is a nine cell cage so every cell is different now these are already in row four that's a knowledge bomb for you those cells in row four are in row four but row four needs to have all of the digits not just these so these three digits here have to appear in row four but they're not in those squares well we actually know the colors of these two squares so we know this one well in fact it's probably best to focus on the green one the green one where does the green one go in row four green cannot be orange and it cannot be grey we've proved that with the work we've done in column seven eight and nine so the only way where place this square can go is there and i might have to find a way of highlighting that i think because they are so far apart i won't remember it let's make those black no i could use purple oh that's much more exciting yeah i haven't used purple yet right these two can be purple now this this square here therefore must be the same as this square here because whatever is in this cell cannot have appeared in row four because it can't repeat in this cage it's gray so it must be there so these two are the same and those two are the same i don't really have enough colors to keep track of all this but i'll try and remember that so those two and those two are the same purple right i see this is lovely it's absolutely gorgeous look what this does in box one with purple purple by sudoku can't go there but also purple can't go here by sudoku either and purple can't repeat in its own cage so it can't be there so that square is purple so now purple is in one of those purple is in the circle of its arrows so it could be quite a large digit which and if it goes on to those squares it would have to be quite a small digit at the same time purple one of those three squares another opportunity for it to be on an arrow can we do any more with purple i'm not sure um [Music] purple uh sorry i'm getting myself i'm getting muddled up now this is not good um this shape is that useful ah oh yeah that is that's incredible right okay yes this shape is where we should look now because this is absolutely beautiful look at this domino where does this domino go in this shape this domino here i'm gonna have to use another color it's essential basically the this black domino it obviously can't go in those squares this is a nine cell region so we know we know this domino has to appear in this region somewhere well by sudoku it can't be in those two squares it can't be in those they're already in the box so this is a black domino here now look this black domino sums to a purple square so this square which sums black domino must also be yup purple now purple is on the arrow there that's interesting purple purple is could this be purple if it was three oh no hang on hang on hang on hang on no of course purple is green purple is green this is the key purple is green so if purple is green and it is basically because although i've labeled it purple it's in a green stripe if purple is green which one of these three squares by sudoku is purple it's the green one i tell you i think i would be committed if people actually recorded some of the sentences i say on this channel and played them back to a policeman so now this shape comes into its own because now none of those can be purple because they're in the box with the purple this purple means none of those can be purple so this is purple that means that's not purple so purple is now known in box two can this square be purple no because we can't make purple plus whatever's in this square add up to purple we can't put zero in this square this is not purple so by sudoku that is purple from these purples so purple we've got we've got eight purples in the grid so now that square which is green is also purple and we've done all of the purples and now we have to stare and think about what this means oh in fact that's purple that's on a four cell arrow um this is very interesting because um there's sort of pressure from both directions on purple now this this is summing digits so this would suggest purple wants to be high this is on a full cell arrow which is pushing purple down so if you make that double one double one two we could make this as big as five so five is the maximum that purple can be and 5 right purple is 5 because this is the key is this square let's look at this square now can we make we know from this arrow or this arrow in fact the purple must be at least three because if we try and make this two we can't put double one on the arrow so purple is three four or five by the time we get to this square now if purple is not five in three it's three or four let's try four just to show you these two squares would have to be a one three pair but but what will we put into that square there's no option it would have to be a one or a three you cannot put a digit into the purple square that can only be sort of dissected in one way so because because it needs to have two ways of being made up from these two arrows and this square is always going to be a problem if there is only one way of making it so this has to allow two ways so this is five and purple is five and for the whole grid whole purples get filled in and that's going to be powerful for this arrow which now now forces double one here because double two already takes us to nine this square must be a two this square must be a nine and we are cooking with gas we've got two and nine in orange so there's got to be a two nine pair up there we've got one in grey we've got three or four here because this oh no no no hang on ha no we can do better than that this domino here adds to five but it can't include a one so this must be a two three pair and there's a 2 here so that's 2 that's 3 3 is now in one of those two squares i bet it's this one yes it is because if it's three here this would have to be a one-two pair and the two would clash so the three goes there that's not three this must be a one four pair so black is a one four pair so that's a one four pair what a puzzle absolutely incredible um one has to be in one of these three squares um [Music] okay what now it must be i must be able to do something fairly simple here i think we can maybe this arrow this arrow's got five on it so once this has got to be at least one so the square's got to be at least six okay this square maybe not quite i wonder whether this the fact this square obviously needs to oh no hang on no that is useful this square has to appear in this in this cage so it can't appear in those squares the five one and the four are already appearing in box four so this square and this square are mirrored and they can't be blue so this square this square then goes into one of those cells right i am running out of colors big time here um four two three four ah right okay now let's look at blue blue cannot be one two three four or five so blue is at least six but it's going on to an arrow with a three so blue is six blue is six no not nine blue is six and that's a nine so and blue is not the same as yellow so there's a six in one of these squares um nine is in one of those squares by sudoku oh i was about to rule this out but that nine is not actually in this cage it just looks very close to it [Music] this is a 9 3 domino we know that we know that these three squares mirror to here so this must be a nine nine is not yellow so this becomes a six nine pair at the top of the column it's just incredible it really is incredible um now one and four look have not appeared yet in box seven so oh one oh no one is not quite fixed oh although hang on no i don't think one is fixed i think one is in one of these two squares by sudoku but this could be one without being yellow so we can't rule one out of this square i don't think um [Music] if this was one it would put one into one of those cells and that would be nice oh two where does two go yeah where does two go in box four two cannot be yellow because we know that that will force two to be in one of those two squares and that will clash in the box so i think two can only go there which means this is two which means that's not two and these three squares are three seven and eight and these squares are seven and eight and i'm i'm worried about my colors now this is going completely nut oh this can't be three because it's got to be the same as that square so this is seven or eight this is seven or eight i don't really like using the yellow i have to say i might get rid of that it i find it really awkward because the cursor is yellow um those two squares are the same oh i could get rid of purple i can get rid of purple now i've done purple so these can now be the new purple um right these are the new purple purple hang on hang on hang on hang on purple yeah isn't there just a simple bit of sudoku with purple here purple has to be in one of those squares but we also know at the same time purple has to appear in this cage now purple cannot go in those three squares because this is purple so purple needs to be in these squares well it's not here and given one of these three is purple none of those is purple so the only square that meets the criteria of getting something into this cage and at the same time being purple and being in one of those three squares is that one that is purple and that's broken my my greens up again so one of these two squares is purple one of these two squares is purple um one of these three squares is purple oh no hang on this is that right this purple's on an arrow uh that's very surprising given it's a seven or an eight so that fixes this this this arrow is fixed because look there's a seven eight pair in row four so this square has to be higher than seven or eight because it's the sum of those two digits well the only digit that will work is nine now this square cannot be a two because there's a two here so it must be a one we can't put three here because three plus seven is ten so this is all fixed purple has now become eight out of nowhere this is seven this is eight this is eight this is seven eight is in one of those squares now don't know if we know which one eight is not in those squares seven oh no seven is not for seven is already done um oh i see these are one four and eight okay this is not eight right let me just take stock a bit here and try and get my head around what's gone on we've now got we now know purple is we know purple is green is eight purple is green is eight remember that so purple is green is eight so there's an eight down here there's an eight up here right and the lovely okay so they can't we can't put eight in the circ sorry we can't put eight on the arrow because that's going to force nine onto the circle which will clash so eight goes in the top this is not eight that's not eight anymore if that's not eight this is not three where does a go in row two it can only go here one of these two squares has got to be eight and okay one of these is a we knew that already this arrow needs to this arrow needs to not be three five so this is one seven or two six so that's 1 2 that's 6 7. so 1 2 4 triple in row 2 now so this r this square is not 2 so the only place for 2 now in orange is right at the top get rid of the 2 from this square and that's actually really nice because yeah this one two four triple ruling two out from here and forcing it here now bounces back there and forces that to be a one and that forces this square to be a seven and that forces the seven and the three okay so now i can get use the one on the one and the four i can get the two here that fixes this arrow and suddenly everything is coming up roses isn't it we've now got six nine here ah now no hang on better than that i now know that the green slither is five seven eight so that's got to be seven this has got to be a seven eight pair seven eight twos and nines there's got to be a two down here no that is not resolved yet okay let's just take stock what have we now got what have we now learned this box is incredibly restricted threes fours and sixes yes that's a four this is a three six pair there's now four in the gray so there's got to be a four down here there's got to be a four up here i don't know if we know the order if i can fix which way round these go we will be away [Music] can we do that somehow i'm not sure but we do know these two squares have got to be two and nine just by sudoku and there's a two here so that's two that's nine there's a two in one of those squares nine nine has got to make an appearance in this cage it's not there it's not there and it's not there and it's not there because of this nine here so it's there exactly there nine is now in one of those squares and these two square are the this is going to be interesting because these two squares are going to give us those two squares oh in fact look i know this already i've done this logic already i am so stupid sometimes but look it's because i haven't got my coloring sorted out we worked out right at the start of the video that these three squares here mapped on well the five is repeated here but this square and this square are the same this square and this square are the same so this is nine this is four that might not actually be as oh it gives us a six here which and that six disambiguates the orange six and three this must be a two six pair there's a six here six and two this has got to be three four there's a three here i don't believe it this is a one four eight so this is a four this is a one this is a seven or an eight so that this should be a two then the eight up here means this is a seven this is an eight this is a seven um good now those two squares have got to be three and six which we don't know the order of i think i think we've basically used everything now apart from maybe this cage so this cage hopefully will help us to finish the puzzle um we still haven't put ah yeah we haven't put one in this row one can only go there so this square's a four or an eight we've now got five digits in this cage we haven't got three four seven or eight let's just put those in and see what we can eliminate we can eliminate seven from those two um three from that one uh okay well i suppose that gives us a three four eight triple in this or yeah in this box uh hobson's choice this is gonna be a six that's a six that's a three so this is four seven and eight in some order that's obviously that's gotta be a four actually this seven is quite nice now that gets the eight and the seven placed this can't be eight anymore whoa and this square looking up this column this has got to be a three because it can't be a four so that gets us all of this done that square's got to be a three what do we need we need one four six and nine so this is nine four pair therefore we've got to go nine four nine six one six and that looks like we've finished it yes brilliant absolutely brilliant puzzle good grief that was clever um and i think i've missed a bit of the cleverness of it to be honest during the solve i think i cottoned on relatively quickly to what was going on with the stripes down here and then then it gets incredible doesn't it it got incredible because we were able to show that these three squares mapped to particular digits along this row and i forgot to use that later in the solve i got the fives well i didn't know they were fives but these two squares being the same was really nice because it allowed me to work out that this square had to map to this square in box one that's quite i mean it's quite gorgeous and then with what fritz dis had done with this domino mapping to this domino allowing these two squares to map to each other and that then going through the grid like a dose of salts it was just amazing so you get these fives early on and then it's really just a case of picking off all the all the sort of not obvious digits but the way that the geometry helps you and it did keep helping us but i was a bit slow up here to really i think fully appreciate the effect of these sort of ice cream stripes in columns seven eight nine but what a brilliant puzzle let me know in the comments how you got on whether you raced ahead of my time or whether you were a bit slower and um thank you so much for watching and we'll be back later with another edition of cracking the cryptic [Music] you
