"Exhaustment" I like that. It's "excitement" and "exhaustion", but it's interesting to hear how someone thinks to say it when they don't have ubiquitous experience with the English language... Actually, I just double checked and "exhaustment" is a real word though it has fallen almost entirely out of use, so there ya go! You showed me, haha.

[@yurdp]

🤯🤯🤯 I’m amazed at the insanity of this puzzle. It’s like trying to weave out 5cm of slack from a ridged knot 1 micron at a time.

[@trickyricky2903]

Bringing bigger and bigger puzzles! So funny! I really would appreciate knowing how many moves each puzzle has. I expect there's some equation to put a figure on it.

[@mangomango6991]

it's impressive that from the start you had such a clear idea of how it had to be solved, so (for you) the challenge was largely one of labour and concentration

[@creageous]

Mainly concentration because it looks to be repetitive and boring. Chris Ramsay does a 5 hour solve of a custom puzzle and it's never boring.

[@landsgevaer]

That 10x10 looks like as much fun as the Towers of Hanoi puzzle with 20 disks...

[@TheRealSugarShane]

That was quite possibly the most palpable relief I have ever heard in your voice after solving a puzzle haha

[@Mr.Puzzle]

😁😂

[@twilighttrinity]

Ok I had to pause the video after seeing the biggest of those Constantin square puzzles and do some number crunching... Tl;dr it's a bit beyond my maths ability! But I think the biggest probably requires over 1 million moves, or to use the naming scheme of Leontev's cube you could call it "The 2 Week Puzzle"! ~~Warning, bad maths follows~~ As best as I can guess, the number of moves roughly doubles with each extra slider, so x4 with each bigger puzzle. It's pretty complicated, as to move a slider, you need to move all the previous sliders that cross it (eg to move slider 6 you would need to move sliders 1 3 and 5), but also sometimes later on, the sliders are already in the correct position so you can get the first half-step without needing to move certain other ones. For example in the 2x2, to move slider 4 the first half-step requires 11 moves, but the second step only takes 8 moves as you can immediately just move slider 3 back. I made a little model of the 3x3 to try out and got these numbers for the required moves to move each slider fully in for the first time: 1 = 1, 2 = 4, 3 = 9, 4 = 19, 5 = 40, 6 = 77 So my guess of doubling each time seems kinda ok? The actual formula for the number of moves is probably much more complicated than just x2 but honestly I have no idea where to start to work it out! This also doesn't actually *solve* the puzzle, i.e. move the little ball to the exit (to be honest I'm not exactly sure what that requires just by looking at it, I'm guessing you need to have pairs of consecutive sliders in the same position to move the ball across?) but the way I see it, you're definitely required to _at least_ move the final slider in, so these numbers are a good lower bound for the number of moves needed. So without any better place to start, if we just start from 77 and double it 14 more times (to make up the 20 sliders on the 10x10), that gets us to about 1.26 million. Since all my working is incredibly rough, my guess would be that actually moving the 20th slider would require less than that (but getting to the actual solution might make up some of the difference?). 1.26 million moves at one move per minute would be take 14.6 days... Not sure that Mr Puzzle would be willing to go through all that, somehow! Maybe you could do 1000 moves a day, would keep you busy for 3-and-a-half years or so :) Anyway would be interested to see if anyone can improve on these horrendous estimates (I feel like that Brilliant ad is directed at me and my poor maths haha)! Scrolling through other comments I see Dysan27 gave a number of 1,572,862 (3 x 2^19), would love to know who's closer...

[@HarrisD214]

Imagine if he realized at the end he’d forgotten to hit record.

[@HarrisD214]

@Captain Bruh Then I am glad to have continued the ancient tradition.

[@Dargonhuman]

What's ironic about that is, unless they said anything, we'd never know as there literally wouldn't be any evidence that they didn't hit record.

[@Violaetor]

This seems to be a Tower of Hanoi style puzzle, where the number of moves is "exponential" to the number of discs

[@shadesmarerik4112]

solving those puzzles is weirdly a p problem, though the number of steps are np

[@landsgevaer]

@@shadesmarerik4112 You mean determining the next move is polynomial, I presume? That is not so weird, is it? For instance, in the travelling salesman, determining whether a solution path is shorter than some distance is polynomial, but checking that it is shorter than all other paths is non-polynomial. In a sense, even for the most complex algorithms, one sufficiently detailed step of the algorithm is polynomial... ;-)

[@beniborukhov9436]

Those NxN puzzles seem like a good opportunity for students to program a robotic arm. Because let's be real if you solve them manually, you're either alone on a deserted island or need professional help.

[@Punmaster9001]

As a kid, I had this round puzzle with 10 pegs on it, labeled 1 - 10, and you had to slide them back and forth starting at one, in a sequence similar to those slider puzzles. That just became fun to do as a sort of "I'm bored and need to do something with my hands" kind of way Oh yeah, the idea of the puzzle was to get all 10 pegs to the outside. I think it was like 1 moved the most, so you had to move 1 out, then 2 would move out, then move 1 back in, then 3 moved out, then 2 back in, and then 1... I forget exactly, but the 1 peg got warn out after a long time of playing with it. Still remember it fondly
