  • ** TODAY'S PUZZLE **
    It was always going to be difficult to follow yesterday's ridiculous puzzle by Jay Dyer but, when you need a genius to help you out, the TotallyNormalCat is a reliable creature! Their latest puzzle (called Boiga Irregularis) is 100% rated on Logic Masters Germany but is only of average difficulty - a rare combination indeed.
    Play the puzzle at the link below:
    tinyurl.com/3ufffx2y
    Rules:
    Normal sudoku rules apply. Draw a one-cell wide snake of orthogonally connected cells which doesn't touch itself orthogonally; the path begins in r9c1 and ends in r9c7. Adjacent snake cells must differ by at least 5. A digit in a circle is equal to the number of snake cells in the (up to) 9 surrounding cells, including itself. The snake must visit each circle.
    If you manage to solve this one and want more sudoku then give this puzzle from Sam Cavnar-Johnson a try:
    app.crackingthecryptic.com/su...
    It's a classic sudoku with a very cool trick. On Patreon we've released a solve video showing Mark's solve (not knowing the trick) and then Simon's explanation of how to go about it differently :)

    Hi Simon. I love watching your videos before bed. Unfortunately I often come across the issue of falling asleep to the sounds of your soothing voice and the comforting thoughts of logical deduction. I am often left unsatisfied and without conclusion after such beautiful breakthroughs. Thus, I have a request. If you could take a few seconds every 10 minutes or so in each video to suddenly scream “WAKE UP SLEEPYHEAD!” As loud as you could into your mic, I, as well as the rest of the community I’m sure, would greatly appreciate it. Thanks.

  • @f.b.jeffers0n
    @f.b.jeffers0n Před 2 lety +116

    As a strong red-green colourblind person, 'red and green' refers to similar shades of them, i.e. very dark ones. The hardest to differentiate are blue + purple and green + yellow, but Sven has been working wonders, because I can tell all the colours apart now. If you put blue/green next to purple/yellow, I can't point out which is which 100%, but I can tell them apart. There has been a significant change for the better.

    • @Tahgtahv
      @Tahgtahv Před 2 lety +6

      Being "red-green" colorblind myself, I deal with this a lot too. I can, technically, tell them all apart but blue/purple, and green/yellow require a large amount of concentration. The problem with the designation is the term covers a wide range of issues affecting the red cones, the green cones, both, or in the worst case they don't detect different things. I believe the most common as you and I have, is we can't tell the intensity of red. (In a color triple it'd be _GB). Much rarer is where red equals green (eg an effective triple of RRB, or GGB). In between is reduced, but not missing, detection of one of the 3.

    @lewsouth1539 Před 2 lety +36

    *Boiga irregularis* is the brown tree snake, also known as the brown cat snake. Members of the genus *Boiga* are commonly called cat-eyed snakes, or simply cat snakes, because the pupils of their eyes are shaped like those of cats.
    When I first saw the thumbnail, I was immediately reminded of the novel *A World Out of Time,* by Larry Niven. Most of the story takes place 3 million years in the future, at which time similar creatures, referred to as "cat-tails", exist on earth. (As I recall, they are not a major plot element, and their origin is never explained.)

  • @hibernator8198
    @hibernator8198 Před rokem +1

    I always appreciate that Simon must have some logic to explain why a cell is the value it is. I got the start of the snake as a 7 by using the fact that the snake is unique and say if the start was 8 it wouldn’t be unique because 8-3-9 is just a valid as 8-1-9. Obviously, I got the end being 8, which did reveal the 7 as true eventually.

    Hi Simon, with the colour blind problem, from my experience of being red/green colour blind ( there are obviously different types yellow/blue for example) it is the shades of those colours, that are issues not the two themselves. I.e. a red/green cell is fine for me to see.
    For example I find it near impossible to distinguish between the blue and purple ( purple having the red I component) that you have used occasionally in videos or unfortunately the cells end up next to eachother by chance.
    Either way thanks for trying to cater to us 👍😊

    A small suggestion: When Mark posts, the link to the puzzle appears in the very first line of the information below the video, and that means you can see it without clicking "...more". When Simon posts, that same link appears after a (nicely written) paragraph about the puzzle, but that means I have to click to expand the sub-video information to see it. Collapsing that information means scrolling down through several screenfuls of text and links about the apps and the discord server and such to find youtube's unhelpfully unadorned button "Show less". I find Mark's approach a tiny bit more "user friendly".

    I'm confused. At the beginning of the puzzle why can't the circle in box 3 be the 6 and have the W pentamino over it? Simon decided it was box 2 and never even considered box 3. For example, the snake could enter box 3 from R2C6 then go clockwise around the outside of box 3 to the circle then exit box 3 into R4C8 then go west to R4C7.

    • @jefffrank177
      @jefffrank177 Před 2 lety

      I skimmed through parts of the video so I don't know how Simon explained it, but due to the circles in box 3 and 4 being an even number of moves apart, a high number in box 3's circle would place a high number in box 4's circle, and being in the middle of the box, you can never put a 6 there as it would need double 1 surrounding it within the same box. (It's shown that you can never get a 7 8 9 on a circle so the only high digit possible for a circle is 6.)

    After watching for a while now I just recently started doing these puzzles using SudokuPad so they take me ages to do due to just not seeing things.
    This was a great puzzle!
    I got stuck twice once at the start and once at the end. I managed to convince myself early on that it was completely impossible because I failed to see that it could join at the top. And at the end I completely failed to see how to resolve the deadly pattern.

    I would really love to see a setting video about this puzzle. I can just see the two big pieces: the checkerboard pattern of high and low numbers on a german whispers snake and how there's only one way to get a high number snake count. But how on earth do you set a puzzle this excellent with just those ideas in mind?

    As soon as the circle in box 4 is known to be low, can't you just write in a 3? It can't be 4 for the same reason it can't be 6, and it can't be 2 or less and still pass through the circle and carry on...

    Very very fun - a very nice puzzle and video. And yet another spacial-defining puzzle. I will say, these seem so easy for Simon, I really enjoy watching him solve them. And they are making a bit more sense to me, too - maybe I'll try it one of these days. Incidentally, I was curious to learn more about the word "boiga" and found that not only is "boiga" a "cat snake" as you point out, Simon, but specifically "boiga irregularis" is a brown tree snake - i.e., the actual scientific name of an actual snake!

    @Raven-Creations Před 2 lety +1

    Outstanding puzzle. Not too difficult once you get started. For me, getting started was a similar process - the 3 was an instant write-in. I initially thought we were restricted to 345 in the circles, then realised by bishop's move that we needed at least one high digit, and worked out there was just one way to hit 6, and only one circle where it could work. After that, I found it pretty straightforward, with a nice flow. As usual, you seem incapable of thinking about different rules at the same time. If you think of both sudoku and snake rules simultaneously, it's so much easier than snake - pause - what do I do now? - suduku? - yes - pause - now what? - snake? etc. I have seen a couple of puzzles where ignoring a rule was actually easier, because it made it easier to focus, but by far the most common situation is that you need to consider _all_ of rules, _all_ of the time.

    I didn't notice this when I was solving it myself, but technically the statement at 47:21 knocks out one of the two options.
    My reasoning: If it's an 8 in the final solution, the line could go either right or up, which means there would be two solutions. Therefore, there cannot be two solutions, so the cell can't be an 8.

    At 47:15, can't we use the property of uniqueness to establish not only that the snake goes down but also R9C1 is a 7 because if it was an 8 that there would be 2 possible snake paths? Are you allowed to use the fact that we know the solution must be unique to make deductions of this type?

    A great puzzle, which was easier after the restart than on the first try. I had thought too complicated because I had misunderstood the rule. I probably translated wrong. Namely, I thought the snake had to pass through all the boxes and the numbers in the circles indicated the number of snake cells in each box and not the nine surrounding cells. In a comparison with Simon, I realized my mistake and had to delete almost everything, only box 2 could remain almost the same. The second run was much easier and I made quick progress.

    Question: Is it valid to use the assumption that the puzzle has a unique solution in order to solve it? At 47:14, Simon says, "We still don't know which way it turns." But only one number could go in the unresolved cell without allowing the snake to turn multiple ways, so he could have resolved that portion right then.
    This is the first time I've noticed something like this, and I'm genuinely curious if this kind of meta-game logic (probably a grotesquely inappropriate term) is considered by the community to be valid or somewhat bad form.
