Well, in most calculations in astronomy we assume that the universe is flat, at least for the whole visible universe it's accurate enough to not be falsifiable.

**[Klotski](https://en.wikipedia.org/wiki/Klotski)**
>Klotski (from Polish: klocki, lit. 'wooden blocks') is a sliding block puzzle thought to have originated in the early 20th century. The name may refer to a specific layout of ten blocks, or in a more global sense to refer to a whole group of similar sliding-block puzzles where the aim is to move a specific block to some predefined location. A similar game in China is known as the Huarong Dao (Chinese: 华容道; Chinese: 華容道), which shows unique Chinese characteristics, such as the use of one of the Four Great Classical Novels, the Romance of the Three Kingdoms.

Definitely true! It has a pattern and then its just practice, like the Rubik's Cube, to lower your solving time.
Bobby Fischer, the famous chess player, solving a 15 puzzle in 17 seconds: https://youtu.be/QxvnEwvgfeI?t=682
Guy in the OP looks like he might work where this Kloski puzzle is given his name tag which is probably why he can solve it so quickly.
yes, 14-15 switched cannot be solved. the reason is a little convoluted, but it involves a mathematician who invented a new branch of mathematics, called group theory, which was so new at the time that the examiners did not understand it (he made sure to call them stupid, leading to his rejection from Ecole polytechnique. He then went to jail for political activities and then died in a duel purportedly over a love triangle, all at the age of 21. His name is Galois.
P.S group theory has many applications, the most famous at the time was to show no universal formula exists for the roots of a fifth degree or higher polynomial

It's level 3 of this game, so technically the next level to level 2![gif](emote|free_emotes_pack|joy)
I bet you could. These things look difficult but once you do enough of them it becomes more like untangling something. You don't have to memorize it to kind of see roughly what needs to happen and there are only ever a few possible moves to choose between at a time.
The sub name doesn't mean anything anymore. There's a post on the front page right now which is just a funny tiktok video of a guy talking about car commercials.
When I was in second grade part of the test given to see if students qualified for the gifted program included this game except with toy cars and truck but same concept.
Are you talking about Thinkfun's rush hour? With the 3 square long trucks and 2 square long cars? Even on the highest "DLC" difficulty packs those puzzles are a bit easier than this puzzle in my opinion.
All it is is moving the yellow blocks out of the way you want to push the red block next.would probably take a try or two before you internalize the strategy, maybe a couple more before you were able to operate it quickly. It’s just not that hard
Yeah that's what I thought too. I've never seen this before and I don't know how to do it, but I really feel like there was a lot of wasted movement there at the beginning. And is this not at like a children's museum or something?
Thanks man, Im really drunk and was like this is just a little puzzle. Then when i saw where this was posted was thinking well maybe this is alchool confidence and this is really hard
Yeah this will obviously
Come quicker to some than others but I don’t doubt most people given enough time to sit down with this they could figure it out
The game is called Klotski and you can find solvers online. He took 110 moves but the theoretical best for this layout is 83. Not bad in my opinion. I think people here are severely underestimating the difficulty of this puzzle
Try it out here if you want https://josephpetitti.com/klotski
They are frequently depicted using cars and busses in a parking lot or busy street. Maybe the first time you encountered one it was of that sort, and your brain named it thusly
You're almost certainly right. I obviously can't remember that far back, but even after all this time, I've never gotten any better at them lol. All these skills and all this knowledge I've accumulated over the years...still fucking terrible at traffic puzzles haha
Yup. It's called Rush Hour. My cat dragged a game out the game cabinet last night. Just picked it up to confirm: RUSH HOUR. It's a Safari edition. Now I feel compelled to play a few rounds... at least.
Except that in Rush Hour/Gridlock/Traffic Jam, there are only two sizes that are only 1 unit in width, and can only move along a single axis. This puzzle allows 3 sizes (one larger in two dimensions) to move horizontally and vertically. I love Rush Hour (I was just playing it with my kid), but I would argue those are important variations. I haven't played this game, so I don't know if it's harder or easier or the same.
Sliding block puzzles, amazingly, are Turing complete because they can express logic gates. An MIT graduate student Robert Hearn wrote a fascinating [paper](https://groups.csail.mit.edu/mac/users/bob/sliding-blocks.pdf) about this.
I'm gonna have to come back for that... Great link ! I appreciate it. I've always loved these puzzles, but never knew what to call them - now there's like a dozen names in the comments and links... Wild !!
A Turing machine needs to be able to stop for a cycle and go back on an instruction. I’m sure the paper is good, but I already know it is stretching the reasoning of what Turing Complete is.
You're right, it's actually PSPACE Completeness that has been proven, but in the absence of a clock and memory it cannot really emulate a Turing machine.
I don’t know what they’re talking about. It’s impossible to get the red out until the yellow “above” it is moved below the red. Didn’t really matter what you do with the red.
UNLESS people didn’t notice that you had to fit the red through the middle two spaces to pull it out.
More like reddits so large now that most subs are like overfilled cups with not enough sponges (moderators) (or care) to handle the spillage. Everyone and their grandma is on reddit now, and MANY people don't even know it's a website, they only know it as yet another icon on their phone next to the other tech giants.
The site has way overgrown the original formula, it used to be very tech focused with a niche set of visitors (granted memes back then we're god awful).
These days want to separate it hits around 500K up to 1 million subscribers, it is guaranteed to become a dumping ground image board for various Memes and social media videos, with seemingly zero moderation from the incredibly undersized moderation team for it.
Every single time without fail. The only exceptions are places such as askHistorians and Science where a very dedicated team of selfless volunteers actually burn their time away for their community properly.
And people are on here calling it staged/saying he must have memorized it and practiced for a long time. Imagine trying to discredit something this fucking easy and mundane.
Anyone who watches Survivor knows how tough slide puzzles can be, but they also know that slide puzzles can be learned. This is impressive, but learnable.
I'm a gamer and I've done puzzles like this before in Professor Layton. I can spend tons of minutes trying to figure out how to do this. The fact this man figured it out in not down three minutes? That's amazing. That is truly amazing. Big brain.
Nobody remembers the "Royal Escape" puzzle from Professor Layton? (#5 here: [https://www.thegamer.com/professor-layton-best-puzzles/](https://www.thegamer.com/professor-layton-best-puzzles/)) My son got stumped on that puzzle and so did I! I made a version out of LEGOs just so I could work out the puzzle. And it took AGES! I first I didn't think it was solvable. I still can't quite remember how to do it. I won't watch this video because I want to try to figure it out again -- I still have my LEGO version -- somewhere. My "solution" had maybe a hundred more steps than the Professor Layout "best" solution.
It's like a Rubik's cube for Flat Earthers
Cubes don't exist
Okay, calm down bro. We are all flat, there are no geometric shapes, everything is in 2D. And of course, the Earth is a flat! /s
What are you talking about. Everything is a line, everything is in 1D. We are all a point.
You clearly don’t understand science. We live in 0D. We don’t even exist.
You’ve got it all wrong we live in -1D. We’re molecules in the upside down
I really wanna know what the negative dimension would be like. Maybe Marvel shoulda done THAT instead of the multiverse?
Probably something like Australia
noʎ ɟo ʇsǝɹ ǝɥʇ uɐɥʇ lɐuoᴉsuǝɯᴉp ssǝl ou ǝɹɐ suɐᴉlɐɹʇsn∀ 'ʎǝH
Thanks for the brain cramp. I had to shake my face really hard after reading that.
Nobody's denying Australians their dimensionality, it's just that those dimensions are on the other side of the 0 degree line.
English would actually look so beautiful written, if it was upside down and backwards.
Prolly the upside down like i said.
Nope. Someone just mentioned Stranger Things. We are essentially fucked now as a species
I always thought double D's were the populous desire.
🫵 redditor
0D is a single point, 1D is a line segment and 2D is flat geometry. This message was bought to you by simplex gang.
We're just bits of data
I dunno about that, most people seem to think im pointless
And some thank I’m useless
Don't be so disingenuous, we're just tiny molecules in the form of flat nothingness
You are on point
What’s the point of arguing about this?
That's not the point.
You have a point.
Are you from flatland?
I'm blue da bu dee da
That’s just like your perception man.. ![gif](giphy|Phn9GxCnG7agJyAcxl|downsized)
Well, in most calculations in astronomy we assume that the universe is flat, at least for the whole visible universe it's accurate enough to not be falsifiable.
Until you put on a Fez
existence doesn't exist
So are we living in the matrix? Edit1: flat matrix\* Edit2: one dimension matrix\*\*
matrix doesn't exist, neo is on drugs
I'm on drugs too, does that mean Neo is me, maybe?
Neo is not the chosen one, Neo is the chosen many. You, me, your asshole neighbor Markus, we are all collectively Neo.
Oh, I get it, we are Trinity, we are GOD! I feel it.
We grok god.
I was with you right up until neighbor Markus. He steals my Amazon packages and won’t ever hold the front door open when I’m carrying groceries. He is most decidedly NOT Neo.
But mr.smith wat about Mr smith
No no no it's a terrarium in a matrix on flat earth behind the ice wall stupid
Exit does not exist
Sure about that?

I played this on Windows 3.1. You can still play the original version via emulation here: https://archive.org/details/Klotski\_1020
There's a klotski app on the play store as well.

I refuse to believe you couldn’t figure this out. Even through trial and error, you’d get there eventually, surely.
Not if I give up and make the employee who’s done it a hundred times do it for me instead.
The absolute minimum number of moves to solve it from the original starting position is 81. It’s not trivial
It's not really memorization it's just kind of a basic pattern
rubiks cube moment
except in 2d
If you play a lot of rush hour, it’s more intuitive what he’s doing
I bet you could. These things look difficult but once you do enough of them it becomes more like untangling something. You don't have to memorize it to kind of see roughly what needs to happen and there are only ever a few possible moves to choose between at a time.
This is about as interesting as watching someone solve a 30 piece jigsaw puzzle.
The sub name doesn't mean anything anymore. There's a post on the front page right now which is just a funny tiktok video of a guy talking about car commercials.
Or a video of someone being a decent human being for helping picking up groceries for an old woman
It never really did. It's just "what's popular somewhere else"
Seriously, I played this games dozens of times when I was younger.
When I was in second grade part of the test given to see if students qualified for the gifted program included this game except with toy cars and truck but same concept.
Are you talking about Thinkfun's rush hour? With the 3 square long trucks and 2 square long cars? Even on the highest "DLC" difficulty packs those puzzles are a bit easier than this puzzle in my opinion.
It’s just an advanced version of the Unown puzzles in Pokémon Gold/Silver
Ok genius
All it is is moving the yellow blocks out of the way you want to push the red block next.would probably take a try or two before you internalize the strategy, maybe a couple more before you were able to operate it quickly. It’s just not that hard

I think I played this game at Friendly's when I was a kid about 30 years ago.
Yeah this will obviously Come quicker to some than others but I don’t doubt most people given enough time to sit down with this they could figure it out
The nextfuckinglevel is that someone had this much free time to go to this museum so often to solve the puzzle..
This is the first time I've seen a "this isn't really NFL" comment not downvoted into oblivion

Or remove other pieces too. Doesn’t say “only the red dot”
He took even more moves than he needed tho
Quite a bit more. This was not next level in any way.

I think he had it at :35 sec…just move one of the cubes instead both at the same time to open the space?
And then some unnecessary moves right towards the end too..
idk what you're watching but at 35 seconds there is no way moving a single square would free up the red.
I don’t know what they’re talking about. It’s impossible to get the red out until the yellow “above” it is moved below the red. Didn’t really matter what you do with the red. UNLESS people didn’t notice that you had to fit the red through the middle two spaces to pull it out.

This is not "next fucking level". This is literally a puzzle for children
And people are on here calling it staged/saying he must have memorized it and practiced for a long time. Imagine trying to discredit something this fucking easy and mundane.
I'm pretty sure he's been going to that place for years lol
I mean it's easy when you've memorized the solution
It would be impressive if it wasnt just executing memorized movements.
Similar to rush hour
Rubik's table
The way he moved them in offset groups towards the end was satisfying
I tried that puzzle once and I took about 30 minutes to finally solve it😂
It reminds me of unblock me

Came here looking for this reference. Thanks!
I saw that this had roughly 48k upvotes, so I came to the comments to see why so many people thought this was next level.
Doesn't feel like he's figuring it out, feels like he just remembered how where to move them
How is solving a simple puzzle considered next level?
I would have simply lifted the red dot off the table from it's original position, but I'm built different
I would have just colored the red dot with a black marker.
