      I wonder, did the people that thumbed up do it because they know the answer. I tried to think about it, but I became stuck. I thought I had it, until I realized the flaw I made.

    You keep saying that you are a puzzle designer, but could you make a video about a puzzle YOU designed????

    I love that concept. I wanted to play with it the moment it started and I reckon I would have solved. How cool

    So many people saying it's not hard enough to be puzzle of the year.
    And also a whole load asking for the dimensions. I think that shows why it won; it's harder to come up with the idea and actually make it than it is to solve.
    Btw, the dimensions are also incredibly easy to work out. Solve *that* puzzle instead, if it's not immediately obvious to you.

    I made a square card and a rectangle bag like this for a friend on her b-day, and she loved it!
    Thanks a lot FLEB for covering this puzzle

    Bit of a spoiler: I paused the video and scrolled through the comments. The instant I saw the word "origami" I knew how to solve it! And lo and behold, he did almost exactly what I expected. I consider a little more of a "neato trick" than an actual puzzle.

  • Quatrei Quorizawa

    guessed it easily compared to your other puzzles :)

    How can this be the winner of 2012? I know the solution immediately when I saw it.
    I reckon I wonder how bad other puzzles must be in that year if this is the winner.

    I normally can't work my way around a puzzle for the life of me, but this one clicked the moment I saw it! The trick to this one is that it is incredibly easy, leading​ many to over think it.

    That's exactly what I was thinking as the solution--good dimensional thinking!

  • Akuun Reach
    Akuun Reach Year ago

    Maybe I just have a weird mind, but as soon as it was stated that the square was to fit inside the envelope, I knew the solution. Unfortunately, this meant no challenges, which I do so enjoy.

    finally one puzzle i could figure out alone without seeing the answer :)
    i loved how simple and clever this is!

  • Timothy Low

    fairly easy once you figured out there is some form of spatial transformation required to bring the bag over the square.

    This one was very easy for me. When I saw the bag, it was instantly clear, that it had to to somehow diagonally.

    99.999999999% of comment section is "EHH IT ISN'T WELL DESIGNED BECAUSE IT'S TOO EASY."
    Well, smartypants, how hard is it to recognize a well designed puzzle? Hard? Just because it's easy doesn't mean it's not well designed. Please go to puzzle school.

    Not to be a dick, but I solved that one in my head before the spoiler break... Now Im wondering how they decide the puzzle of the year. Definitely the easiest puzzle I've seen on your channel.

    I don't do puzzles often or origami so I didn't see the solution. I like how the puzzle was made of very simple parts. It shows that you don't need very expensive bits and pieces to make a clever puzzle

    it won because it is simple but counter intuitive. at a glace seems impossible but in truth it is very easy. take a genius to make something so simple and easy and transparent but have the illusion of being impossible.

    just from the thumbnail, I already imagined the solution. probably from too much origami.

  • Luben Lambov

    • FLEB
      FLEB  2 years ago +2

      You really shouldn't! At the actual event where this debuted, very few people solved it immediately. It's a lot harder than it looks!

    A-HA! Folding a lot of origami paid off! I immediately thought to squash-fold the bag, presuming it had the right area to fit, and lo and behold! That said, it wasn't that hard. :/ Maybe it's just that puzzles are more commonly based around twisting, turning, sliding, etc. Still, I'd like to see this particular type of folding puzzle take off.
