  • Okay, so I looked it up. Apparently, you don’t need to guess in proper Sudoku, when there is only one solution

    Yup, you got it :)

    , but apparently there are also many Sudoku, sometimes printed, which have more than one solution, and so you require guessing.

    Yeah, but only where you have come to a place where a 50-50 guess is needed, when you get used to solving good puzzles you learn how to figure it out, and there is a lot of checkers that you can run on puzzles if you’re not sure, and if you find one with multiple solutions you just evade that source.

    Also There are known good sources for puzzles, ones that are proper puzzles, so the best choice is just to keep at them.

    Also, some sites mention “guessing” as a technique, which I probably took it to mean that you have to do it.

    Guessing is used in speedsolving, where they solve the puzzles really fast. Guessing is a valid technique in picross as well, you can just guess if a cell is filled or not, it’s exactly the same in sudoku, you just cheat yourself, and it’s a big likelihood that you made the puzzle unsolveable, personally I find it not very gratifying to guess, so I never do.

    Since I believed guessing is required, I would leave the puzzle where I got a bit stuck, assuming this is where I need to guess.

    Yeah, some of the techniques, like finned fishes, Alternate inference chains and 3d-Medusa and so on can get a bit involved, so if you haven’t seen them before it’s hard figure them out by yourself. I used to moderate the r/sudoku sub over at reddit, where we used to help people solve a lot of puzzles they were struggling with. But really difficult stuff like that usually aren’t in printed puzzles, they seldomly have anything more complex than an X-wing.

    If you want to learn about techinques https://hodoku.sourceforge.net/en/techniques.php is a really good source, and hodoku is a really good solver too in case you want to learn, if you want something online there is https://sudokuwiki.com which is decent as well :)

    Thanks for the comment! If I start to like Sudoku again, the blame would be all on you! 😀

    Hah, you’re welcome, I’ve been solving for around a decade now, and it’s still fun to me, so at least there is something for it.










  • You’re right that the theory is not about God, but explains the origins of the universe.

    How so? I don’t see what you mean here, it doesn’t explain anything, it just builds a level of assumptions on top of something, basically explaining something with an untested hypothesis.

    what I said about God is what I think is a logical conclusion.

    If you Agree to the premises I guess, but I don’t, so it explains nothing.

    If something has a beginning, then it must have been kickstarted somehow.

    Then who kickstarted god? Or does he/she/it for some reason get special treatment here? (This is special pleading)

    What kickstarted it is by definition its creator.

    If I kick a stone down a hill I did not create the stone even though I set it in motion.

    And this applies to our universe, in my opinion.

    Hmm, I don’t see how you evade an infinite regression here, unless you break your own rules and give one link in the chain an “eternal always existing” modifier. We don’t know that anything eternal exist, or even that our universe isn’t eternal (extisting eternally as a singularity before spreading or a part of a bigger multiverse that we cannot perceive)

    It is merely a statement that they must exist.

    It is just assuming that something must exist, since you’re building your logic on very shaky premises that we cannot prove.

    An effect must have a cause.

    Must it? Or have we just never seen the contrary (black swan fallacy) Who caused god? like I said before you can’t get away from that without special pleading.

    I apologize for sounding pretentious earlier, that was not my intention, but I can see how it came off as such. And apologize for misunderstanding your intentions as well.

    Water under the bridge :) No worries :)

    Also I notice you have some downvotes. Just want to clarify that it is not me.

    No worries, I don’t care about the votes, interactions are worth way more than someone clicking an arrow :)
