    I'm a Top-10 finisher in the US Puzzle Championship and just released a logic puzzle game on Steam! The game is called RYB:

    Me, having zero experience in these puzzles, went out and bought the Cast Quartet! Which is level 6 difficulty.. to put you into perspective, the Harmony is at level 2, and the Devil is at level 4!
    No I'm not even close to solve it

    I remember the cast devil being in my elementary school GT classroom! The other students and I would always be trying to figure it out, I'm pretty sure on multiple occasions one of us figured it out but weren't sure how we did it XD

      These aren't tavern puzzles, but that is a class of puzzle! Tavern puzzles are take-offs of the horseshoe puzzle and are usually made of much thicker metal.

    My dad bought me the cast devil on a road trip around Australia. He said that if i could figure it out by the time we got to townsville, he would get me an ice cream. Kept me thinking for a while, but i figured it out pretty quickly! very fun!

    You should play your "spoiler break" at the start of your video because it is really just your intro

  • Alex B

    It's so weird that he basically just announces his intro in his videos, as if it were some sponsored advertisement. And in like the very middle of the video.

    • General Milky
      General Milky 4 месяца назад

      Not that weird. What else would he put there? He has a pause so if people who don't want spoilers for the puzzle are watching they can click away.

      Alex B It's a spolier break. If you don't want to watch the solution then you have a warning and time to leave the video.
