    "The Adventure of the Dancing Men" was a Sherlock Holmes story featuring this code is stickman form.

    CTF are super cool, I've done a 24h one at work, slept 3h and finished 2nd. The feeling of solving a puzzle is incredible.

    I wonder if you guys would have fun with the MIT Mystery Hunt. It's a 3 day puzzle event that's free to participate in at MIT. And the winning teams usually have on the order of 100 team members so it might be a good way to get your communities involved remotely too.

    What really grinds my gears with puzzles like these is that there's no constraint or question at the end of the puzzle. So there can theoretically be multiple technically valid solutions that don't contradict the puzzle because no constraints were given. In this case, at least you were eventually given a constraint that it's a 13-letter word. I bet I could use some very involved logic to coax a different word/phrase out of this. "That's not what the author meant" wouldn't be an objective, rule based reason to reject such a solution

      You can submit the solution in the competition and see if it's correct. This style of puzzles is not like a math question with a very defined "constraints". It's a "guess the correct password" thing. There is only one correct answer, and yes, you need to understand what the author meant.

      I don't like these kind of puzzles because they tend to require knowledge people don't generally have. The music box requires to be able to read musical notation (though this is not as bad because you can just google how to read it). The charades puzzle requires you to know The Adventure of the Dancing Men. I have no idea how you would figure the puzzle out if you have never heard of it. It's essentially just random whether someone on your team knows some obscure reference or not. Thankfully they give hints so this isn't a complete deal breaker but it doesn't feel good to struggle with a puzzle just because you don't know a reference.

      Not knowing something is normal
      This is a competition for fun its aim is not to be fair
      Also remember they got internet and plenty of time I am sure they didn't know about the dancing men

      ​@@HoxTop you're surprised that a secret code might have some niche references intended for the author and desired recipient to know... That's cryptography bro! Also many of these are somewhat on the nose, if you type dancing men cryptography into Google you'll get a breakdown of the Sherlock Holmes dancing men alphabet straight away

    you can also place notes before beginning and after end of song but they don't play

    Is the competition name "The Gold Bug" a reference to the Edgar Allan Poe short story of the same name? -- The short story is about solving a substitution cypher, which would be fitting for the competition.

    Given the effort required to tackle the Music Box challenge, I must say the title at the top of the music sheet is pretty fitting

    I'm happy solving this puzzle gave you so much excitement, but you're the only one to solve it because ... you a) continued playing after the deadline and b) got to asked the designer questions.

    • @skswldms
      @skswldms 4 หลายเดือนก่อน +27

      @@zackkirako8574 It matters because starting the video with, and repeatedly saying the phrase "I was the only one to solve this" gives the false impression that he won out against all other competitors. But this is not the case.

    • @zackkirako8574
      @zackkirako8574 4 หลายเดือนก่อน +4

      Still confused he was on the team that did win. It doesn't seem he had an unfair advantage and instead used resources available to others. He said at the start of video which puzzles they figured out for the challenge. So still please help me understand what I'm missing.

    I love doing this stuff for Call of Duty reveals (like PawnTakesPawn, or even Cod Zombies itself)
    Im not smart enough to do them, but im happy to throw something out there that may narrow it down... as long as I'm caught up and not 20 steps behind, just left in the dust... confused how they got past step 10. While their on step 45.

  • @RuiPalmeira

    if you "play" the first 4 notes (that are on the bass part), but use the wrong notation (treble), it roughly sounds like a dumbed down version of carmina burana.

  • @asailijhijr
    @asailijhijr 3 หลายเดือนก่อน

    Yeah, it's really annoying when you make a puzzle and then discover that you've made an error that will keep people from finding the intended solution. And then it's really hard to correct the error with a hint without giving it all away.

  • @rlstrength
    @rlstrength 4 หลายเดือนก่อน +29

    Personally from the outside view not a fan of puzzles like this where there is so much open to interpretation and you just solve it thanks to the hints because the puzzle UX is so bad and buggy.
    I'm gonna say it I feel like it was extremely badly designed and thought through
    Congrats for getting it done though, I would also be unable to sleep or think about anything else in that situation

    • @TheEvinB
      @TheEvinB 4 หลายเดือนก่อน +14

      Looking at the overlay Theo used at the end to solve it, I feel like the puzzle creator didn't intend it to be solved graphically. Take the music box grid as an array of 0's and 1's and append them into one long list, then copy the text directly in as a string (without newlines) and XOR them together, and I think you will get the same answer.
      But then getting the grid right in the first place seemed very unclear.
