course um do get them for your best friend in time for christmas along with our merchandise and sven sudoku pad they'll be your friend for life no i'm joking but uh we love it when people introduce others to the channel because it's fascinating how many times we hear the story that somebody mentioned mentioned you to me and i've started watching and now i've realized how much sudoku has to offer um and we hear that a lot unsurprisingly now the rules of this puzzle are it's called remote clones sudoku normal sudoku rules apply arrows in a cell indicate that the nth cell from the clue cell contains the same digit in both directions with n being the digit in the clue cell now that might sound complicated it really isn't let's have a look at this cell for instance whatever the digit here is let's say it's a four that means that there's going to be the same digit four spaces this way and four spaces this way so those two digits will be the same because that's a four that's how this works we don't know anything from that cell about what that digit is except that it's not four because there's a NUMBER_TOKEN sitting there but apparently incredibly we can solve this whole grid without a number given to us just by this knowledge i i mean i find that fascinating i think it is intriguing that this grid solves i even heard a rumor that it solves much harder if you ignore this cell too and i'm not going to do that and it may not be true i don't know but anyway do give this a try on the link under the video um we'll see how it works i'm having a clue what we're going to find out i'm going to start now though let's get cracking now okay the first thing i'm thinking is short distance arrows matter here that must be the case so this at this arrow only has a maximum of three cells that you can put in this because whatever you put in this is telling you either those two cells are the same or those two or those two you can't get bigger because you'd come out of the grid oh and these yes okay these two can only be one or two because they're only pointing up to two cells that way so that gives us a pair um these are quite far from the edges but i suppose it might be worth pencil marking the possibilities frankly that can be up to five this one's better this can only be one two or three oh look look i've just worked this out sorry i didn't see this before that can't be a one because it would make those two cells the same and they're in the same box and that would break sudoku rules so actually that has to be a two and that is a one and that two is now pointing at a one and puts a one here and now that's a three look look at that star that's lovely now this isn't a one two or three i think what i'm going to do is color these cells like that too i've done that so don't let's not worry about that anymore but that three is saying that these two cells are the same this oh look here's something interesting oh that is
