The Metermass Puzzle 

Seeing it all snap into place was very satisfying. It would be fun to make my own version with popsicle sticks, rivets, and foam.

the long piece is 7 units long. because 7 has no gaussian factors, it can't be placed diagonally in the grid, no need to make an assumption there. what's your favorite puzzle that subverts expectations and assumptions?

These videos are amazing. it looks like he does it with no trouble and when you do it, you get headaches. its mind blowing that he does like hundred of videos of these puzzles. its interesting watching him ive been watching his videos for a few hours now. keep up the work FLEB

Another great video

Wow !!! Never thought of putting that first piece on the second row... it would of taken me ages !!

i really like the way you describe your thought process while solving the puzzle. great video!

What a brilliant creative mind this inventor must have!

This is so neat! Watching all of these unique puzzles being solved is truly interesting and shows their creative designs. Love it! ❤️

Thank you for doing another physical puzzle. This one was fun to watch.

If a similar puzzle used a 3-4-5 triangle, you might hide a diagonal somewhere and add some complexity. Depending on how the corners were rounded perhaps. Carpenters regularly use a 3-4-5 triangle for squaring corners btw. It and its multiples are one of the few triangles that form a right triangle.

Somehow when I hear you starting the name "Jean Claude Constantin" I immediatelly finish the name with you and wait for an amazing puzzle :-) I like this one. My niece had the kids puzzle games with penguins on the icebergs, where you had 4 or 5 different pieces of puzzles (some of the pieces were even movable) and you had to fit them into the slots just like the guiding book showed you. The further in the book you went, the harder the game was. At the start it showed you how exactly put the pieces, at the end it showed you only the positions of the little penguins on the top of the puzzle and you had to figure out how to make the puzzle.

This is a very interesting puzzle. Absolutely fantastic! It reminds me of photo masking integrated circuitry. Nice...,

Really love the new setting!!

Well Done Fleb, You Amazed Me Again.

great video. would love to find a puzzle like this.

congratulations on hitting 100,000 subscribers. great content keep up the fantastic work.

It would be easy to tell if diagonal positions were necessary because the rivet spacing would be different than on XY sections.

That was so satisfying to watch!

This video deserves the title of the let's solve

Another great puzzle! Looks like you are almost at 100k subscribers. Well done!

almost 100k subs good job FLEB!

"And there you have it!" best line of 2017

Jean-Claude Constantin sounds like a kick boxing street magician.

"if we assume all pieces go horizontally or vertically" While probably impossible, I now wonder if there's a way to fit it in diagonally...

I like the outside setting.

Amazing!

Fleb remember me from 7000 when you reach 1M! Didn't realize I said flub previously ahahhaahh

this is really cool

satisfying solution, great job!

Jean-Paul Constantine. What a name!

YAY!!!! 100k!!!!!!!! GREAT JOB!!!

Congrats on 100k!!

This is such a creative puzzle! It would've been even cooler if the hinges spelled something or made a letter, but this is a great puzzle nonetheless! Keep up the good work, Fleb!!!

great vid! love your channel!

The shapes of the over and under peices basically show u where they go immediately....

I know this video was made months ago but maby those metal circles that r there to keep each piece together also mean something in bar code or whatever the language is called

Would've been pretty mind blowing if the silver joints actually formed a certain shape upon completion. I wonder if someone could design that.

Heres your baby ma'am what would you like to name him... IMA NAME HIM FLEB

wonderful video dude! I already subbed and liked. how do find all these cool puzzles?

Another puzzle i can actually solve 👍. Those are the best ones 😜😂

Wow, what a great puzzle is this. I have some of the lock puzzles of Jean Claude Constantin and i think i will buy this one as well, so i did not watch the solution this time. Another great video, thanks! Nice surroundings by the way, did you record this in a park somewhere?

Road to 100K subscribers! You can do it Fleb!

Amazing!! How long did it take for you to originally solve this? Keep it up, FLEB!

Would it have been possible to invert the layers ? It seems that using the layer you put on top as the bottom one would have been easier, as no pieces would have needed sliding under another one, only sliding over.

That's a nice puzzle, I'd love to try solving it if I had it :) anyway, when the new PC game comes out Fleb?

Great video Fleb! Have you created any real life puzzles besides from your game?

the numbers doesn't mean anything? i mean if it's only for measurements, it can be just start from 1 for each pieces. or none I thought it was meant to multiply or add when it sits correctly next to each other on the board

Constantine rarely leaves anything without a purpose. Have you found any usage for the numbers on the sticks, or is your assumption his intention was to make it look like a yard stick.

Your friends must love visiting you. I would forget what the time is....

"Rotatating" 😂

your videos are so intruiging becsuse your voice and tone remind me of a calmer version of Sheldon from big bang theory, which is a good thing because he's my favourite character

Are you a fan of puzzle book puzzles? Like the PennyPress Variety kind?

This one was actually easier than it initially looked (to me). Still an interesting puzzle, though.

al.ost 100k nice keep up the cool work

Great puzzle! Nice vid! Is there only one solution?

What do you think about doing puzzles in games. It will probably get you more views because it's easy and quick to put out.

another Constantine puzzzzzle destroyed by Flebby

interesting puzzle!

very interesting puzzle

Cool.

I think i want to recreate this using Technic Lego

I have an idea. Stand it up vertically. Ha.

*me when i watch this kind of vids*: i hate you i wanted to find the answer by myself!! *also me*: probable never going to do this

New subbie 👍🏾

I always forget that name until I hear you start saying it. this is by far my favorite puzzle you've featured. theres something about it thats so satisfying

HELLO FLEB NICE TO SEE YOU

6:01 Watch. It all falls apart on him. 6:04 Nevermind, phew.

This puzzle is the product of a troubled mind.

can you solve a rubik's cube? I can but it takes me like 5 minutes I'm new to finishing rubik's cube.

what magic is this?

If the official solution left holes vacant or had diagonal placements that didn't interlock as nicely as it clearly has here... it wouldn't have been such a nice puzzle. Id feel it was either incomplete or poorly designed.

I wonder if the buttons make up a word in braille? Anyone here know braille?

Lol I would just use this as a fidget toy

Every time he says a fancy word, it speeds up. *the video is three seconds*

The "centimeters" are larger than real centimeters, aren't they?

so close to 1Mil.

Yay

fuck you are my god fleb love this channel aha

how fast can you solve a Rubik's cube?

I already know it.

Do the numbers mean nothing? Why do the numbers exist?

Yeeeaaaaaaayyyyyaaaaaa!

@FLEB 521 more subs to 100k good job dude

Your name is not actually Fleb. Right?

Hi fleb love this new vid keep it up please reply

omg at 0:53 lol

I bet one of Thomas Sanders' personalities would absolutely love this channel! *cough* Logan *cough*

I love your channel but you need to learn how to focus the camera better dude. Seriously.

You lost me at "this piece".

EARLYISH

turn off your autofocus ;)

Mr. Puzzle is better you talk to much and explain obvious things even a 3 year old can visually figure out. Unsubbed.
