The Metal Fifteen Puzzle - Endless Combinations!
HTML-код
- Опубликовано: 29 сен 2024
- Invented in 1870 this puzzle is one of the most popular puzzles ever. Besides the most obvious challenge (sort the pieces 1 - 15 in the correct order) there are endless more challenges. You can also create your own. The more complex the solution looks like the more difficult it will be to arrange the parts in the correct way.

Did you ever try the Fifteen Puzzle yourself?
Mr.Puzzle of course everyone who has or had a Mac or a windows 7 pc has
Mr.Puzzle yes it was a gift from my grandma
I got one from my aunt and uncle many years ago. When I tried to solve it, I noticed that the 14 and 15 were switched after I was done. Much later I found out that those were intentionally made that way as part of a bet by a scam artist who bet that nobody could "solve" the thing because, due to the 14 and 15 being switched during production, it is physically impossible to get it correct unless you take the thing apart entirely. So guess what I did.
Omg, it is the first game/puzzle i ever played. It was the only thing I can play on an old TV, the days without LCD TV and PC. So glad to see the physical form.
Yeah I tried a plastic one
I've had this exact model!
Part of my childhood!
I have to admit, until today I have always hated this type of puzzle. They always seemed to me to be too simple, and as you mentioned, the plastic and wooden varieties get stuck too easily. Watching this video, seeing the quality of this version of the puzzle and the variety of different solutions that can be attempted listed nicely in the booklet, I am now more interested in this kind of puzzle than I have ever been. I can't say that I am in love with it now, but your review has changed my mind significantly!
The thing with the 15 puzzle is the algorithms to solve it are very basic and hard to forget. You could even randomly stumble across the best way to solve it on accident.
The famous American puzzle maker, chess problem composer, writer and chess player Sam Loyd (1841-1911) once offered a $1000 prize to anyone who could reverse the numbers 15-1. People went crazy trying to do it, because back then it was a huge sum. Lots of people bought the puzzle, and you could see them working on the solution on trains and buses, in parks and cafes, and since Mr. Loyd produced and sold them, he became very rich. (By the way, he knew his $1000 was quite safe).
This is my favorite kind of puzzle
Eeeeee 500k subs mate! Halfway to your first 1m :))) You will get there. Keep up the great work
I had a plastic one of these when i was a kid
die dinger gibts ja schon seit ewigkeiten
hatte eins als kind aus plastik und da schon ewig rumgemacht damit ^^
in der grösse, schönes fidget toy
ich bleib aber bei sudoku aufn handy ;)
anbei
bochmal danke für das ugear review
haben ne dicke bestellung bekommen ;D
Viel Spaß damit! :)
I have this exact same puzzles
Done this puzzle about 1000 times on Runescape
I have tried the 15 puzzle, it's my favorite puzzle and i speed solve it, the best time i have got so far is 8.2 seconds
nice
Can you help with notation?
Bobby Fisher did it on the tonight show under 4 seconds I think
Hai Mr.puzzleboy 😎😎😎😎😎
Hi
i solved a few minutes ago
puzzle master, can ypu put the review in the middle of the screen instad of the left side?
Kitteh Cat I liked it.
What terrible music!
I am going to be honest this is the exact puzzle that got me into puzzling infact it is the exact same one my version of this puzzle has unfortunately over the years become rusted and has stuck itself together so its squeaky and hard to move the pieces
the fastest I have solved this puzzle was 50 seconds
I set up my version of the puzzle into the sequence that Mr. Puzzle solved in his video. I solved it in 29 seconds. 50 seconds is still very respectable though.
I remember doing these types of puzzles as a kid, The nostalgia is real. Keep up the good work Mr. Puzzle!
Me too, with the painful memory of the plastic squares getting caught, making the sliding action difficult at times.. i ordered it! As an adult, i want to feel that nostalgia! i am so excited!
Very interesting mechanism. We should have thought of that one when we built our world record 100-piece sliding puzzle...
I solve this in a different way at the end, when I'm on the last 2 rows I stop solving the rows and start solving it by columns, I would put together the 9-13 in this case, then the 10-14, and the last 3 pieces should be in the correct position or just 1 twist away to be
Federico Salamanca ...with a screwdriver lol
That is the more efficient way to solve the last line and is a move that can be applied almost anywhere to make one tile move past two others. It's an essential move for speed solving.
Same thing here. The most difficult part for me is placing several pieces on the right place at once, or thinking in advance so that the next pieces don’t stray too far from their places.
Tiago Marques, You may call me strange if you wish, but I've spent enough time with the puzzle that I have named a fair number of the moves. What you are describing is chaining and priming. Priming is moving pieces into position for a future move (for example, putting the 4 into the 3's place so that the 3 and 4 end up in their correct positions). For this, it's just a matter of patience and proper set-ups. Chaining is creating a chain of tiles that all move into place at once. For example, if you have the 5,6,7 and 8 all next to each other, you can move them to one side and move them all into place as a single body. The trick with this is looking at the entire puzzle and seeing how you can create a chain. Another helpful move is shifting. For example, shifting the 9 and 13 to the left and shifting the 11 and 12 to the right allows you to freely place the 13,14 and 15 in the order that you want (have one tile jump two tiles). All in all, if you want to get better at these types of moves, I would suggest you examine the puzzle in its entirety before and after making any move and seeing how that could help or hinder you further along.

I play RuneScape and one of the things you can do in that game is something called Treasure Trails, which are essentially scavenger hunts with various puzzles to make it more challenging. One of the puzzles that you can get is a 5x5 slider puzzle; I seem to get a lot of them when doing Trails and I've caught myself doing a lot of the tricks you just described. I think I'm going to borrow your terms for those moves from now on haha!
Wow! I forgot about this puzzle! I’m 51 and had these when I was in kindergarten and a couple years after. Mine were plastic. I did solve these when I was very very young. I never learned a “proper” solution I just know I solved it. Also had a 3X3 version that was easy.
I was born in 1870 too
Same
These are way better when it's a picture not numbers.
You could still have a picture of every solution like they do here, with one made up of a picture. It would just look strange. The number solutions all look abnormal except a couple themselves, anyway.
It's harder when it's a picture because unless you've seen the original picture, you can't tell what order the pieces are supposed to be in.
Hey I had that exact version of that puzzle as a kid
Mr Puzzle. Do you own puzzles you have tried, but haven't yet solved? If so, what types of puzzles are they?
I hope he tells us
Yes, of course. But so far non that remains permanenty unsolved.
Usually, I try to solve many puzzles in parallel not one after one.
Some require many hours and I haven't continued yet.
But I have also one puzzle in my collection that I will never solve! Problably noone will every solve it.
Mr.Puzzle An unsolvable puzzle? You have to do a video about it. Would be very interesting to see it, and the comments.
alex z I will wet myself if he meant that puzzle. Got me hook, line and sinker it he did.
alex z oh yeah. The two piece puzzle.
I'm an expert at this puzzle, I did it in runescape with pictures. It was the picture puzzle box. You used to make pictures of the characters and places. it was always my favorite puzzle.
As a true master of this puzzle (I've been playing with it for several years now in my spare time, like on the bus to school or sometimes in between classes) I am happy to say that this is one puzzle that I am better at than Mr. Puzzle himself. Then again, I have spent a lot of time with it, so much so that I have determined exactly how to move the pieces to achieve the pattern that I want. I have also determine the most efficient way of inverting the puzzle on a diagonal axis of symmetry:
Example (start):
1 2 3 4
5 6 7 8
9 10 11 12
13 14 15 _
end:
1 5 9 13
2 6 10 14
3 7 11 15
4 8 12 _
That being said, I'm very happy that one of my favourite puzzles (if not my absolute favourite) has been featured on this channel.
P.S. I do not mean to say that I am the best since there are many puzzles that Mr. Puzzle is better at than I am, I am just happy that this opportunity has arisen where I can express my joy with this puzzle.
P.P.S. If somebody want me to detail my axis of symmetry patter, I can post it, it is just rather long.
Probably not the only puzzle you can do better than me! :)
Craig Kogan DO IT!
Give me ~2-5 hours and I'll see what I can come up with.
Craig Kogan ill be sleeping then so i gotta answer you tomorrow (for my time Zone) but thanks a lot :D
You're a cool dude
You brought back memories from my childhood, I just ordered this one because of you. Thanks
Can someone comment a link to a pdf or something that has the challenges sheet, I have found one of this puzzle (that was used) and it didn't come with one, so I would like to print my own. Thank you.
I remember having this exact puzzle as a kid. Thanks for the nostalgia trip!
I love your videos mr puzzle thank you for making them
This one looks very simple, but when actually doing it, it ends up broken out of frustration.
You know what I don't get? the love of noises, why? just why? I have a Rubik's cube and whenever I solve it the sound it makes is just...why? and then I look on youtube and every youtuber and their mother seams to love loud clicky mechanical keyboards.
Haha, well it seems everyone loves it but you! :D
I have one and I CANT SOLVE IT also I’m using my dads account
I think the more common version of this, is a picture that you have to put together. Exactly the same functionally though.
yes, I also did these when I was a child
I have one of these. Well... actually a really cheapo plastic "party favor" one that slides poorly and locks up a lot. But still a Fifteen Puzzle that plays out identically. I really feel like I should get this one to upgrade.
How I solve it below the "read more" spoiler break. ;D

The first two rows I do numerical order, though instead of putting, say... the 3 in the row just below on the far right and then the 4 below or next to it to rotate-cycle in, I put the 3 in the corner so I can cycle in the 4 faster no matter where it might be as long as it's not directly to the left of 3 (easy to see coming) since I can move whole rows/columns at once. I suppose you could also place the 4 where the 3 is move the 3 below it, then make a space right of the 4 and cycle them in. The same with 7 and 8. For the last two rows, I do them both at the same time in columns from left to right using the corner method. So 9-13, then 10-14. The last three of 11-12-15 should be in place or just need to be cycled around as it would be impossible for them not to be. Thus when you position the 10-14 pair, you basically get 5 pieces at once.
Even though you can do all sorts of number orders and patterns, the difficulty remains the same other than just visualizing what goes where and planning it out like the original numerical order. Though while recognition is the only additional challenge when trying to make something, you "could" however try to do it in the fewest moves as efficiency in itself is an added layer of efficient movement logic.
Anyone else master this by playing the original Final Fantasy?
This is the first episode you've done where I actually have the same puzzle! You're right about how satisfying it is to slide the pieces around. I would only give it a 2 out of 5 difficulty though. The solving procedure is fairly simple and you can use exactly the same basic method to arrive at any given _possible_ combination.
great puzzle but there is actually an easier way solving it. Solve the first 2 on a roll (1 and 2 for example) then place the last of the roll on the 3 place(4 for example so it looks like 1 2 4 _ ). then place the third piece under the forth(1 2 4 _ / _ _ 3 _), and slide the forth back and place the third. That way you dont need 3 roll to fix the first and it takes less moves :)
that was exactly my strategy as a kid! I’m impressed you were able to explain it in writing
Hey Mr. Puzzle, I really enjoy watching your videos. They are so binge-watch worthy! I am however curious if you could maybe introduce a format for bar-puzzles? You know, those little riddles using matches, coins, keys, bottlecaps, straws, etc. Puzzles to get people entertained at a nice, comfy night-out at the bar? That would even further spark my interest! Keep up the good work!
This is one of my favorite mass produced puzzles. It's a classic puzzle that our parents, grandparents and probably most of our great-grandparents played in their time. It's not very difficult to solve, is fun to spend a few minutes any time to fiddle with, and the number of possible challenges to solve is virtually endless. The build quality on this version from Thinkfun is excellent too, and very easy on the eyes. Everyone should have one of these.
I love how he says "chamfer".
+Kevin Squire McLaren I assume that means something like ramp, slope, bevel, inclined plane, wedge? Google Translate is not helping lol
Xaviar Thunders I know what it means... I just like how he says it with is accent.
camphor is a different word
It's an english word, that's why translate isn't helpful.
1.
in carpentry, cut away (a right-angled edge or corner) to make a symmetrical sloping edge.
noun
noun: chamfer; plural noun: chamfers
1.
a symmetrical sloping surface at an edge or corner.
My mother bought one of these for me as a kid. I loved it. I spent so long playing with it. Fantastic little puzzle. Simple and Elegant.
I have the exact same one of this puzzle! One of my favorite things to do is making magic square on it. For people doesn't know what a magic square is, it's a grid filled with numbers in a way that the sum of every row, every column and 2 diagonals are the same.
On this puzzle, the possible number ranges are 1-16 (treat the space as 16) or 0-15 (treat the space as 0) and both are pretty interesting to solve IMO.
Extra challenge: make is so that not only the rows, the columns and 2 diagonals have the same sum, but also every 2*2 sub-squares (this is called the most perfect magic square)
I had this puzzle as a kid! I vaguely recall there was a little book for other patterns to solve too! I wonder if I can find it...
Edit: the book was shown in the video so I'm not crazy
Schön! Das 15-Puzzle mag ich sehr
Wow! ... I love your channel and puzzles! I have lots of them... thk u for helping with the solutions!! The 15 is my all time favorite!!! I take it EVERYWHERE l go \{*,*}/
I think it was invented by Samuel lloyd. I'm 57 now and At age 12-13 I solved it in 20-30 sec making all adults and teachers very impersed. In the USA many years ago someone chanched the position of 2 sqrs made it impossible to be solved. If I had more time I would find the book and give you all more details.
I solve sliding puzzles in the same sort of way that you do for all row up to the last two. Once I'm down to the last two rows, I then work on both rows at the same time, working from left to right - so, for a 4x4 grid, I'd put 9/13 in place, then 10/14, finally 11/15 (and 12 naturally falls into place)
I remember as a kid I couldn't work out how to do the last two rows of puzzles like this and would just fiddle around until it worked out. For the first two rows your technique is totally different than what I worked out; my method is to arrange the first row like x123, bring the 4 under the 3 so that the second row is like _xx4, and then pivot the first two rows once to 1234, xxx_.
I love puzzles like this because they allow so many different approaches that work as well, it's very interesting to see all the different ways people do open ended puzzles!
Completing the rows ,1st,2nd, 3rd and 4th and using the left side drop down right side slide up is the only way I know to do this puzzle in @ 2 min. Also using the counter clockwise square. Any faster suggestions??
Much easier solution: After solving the first 2 rows (1-8), solve the left column (9 and 13) then the next column (10 and 14). After that, the remaining 3 tiles are guaranteed to be in the right order (you may just have to rotate them all around once or twice). This lets you avoid having to move any tiles from a row or column that's already been solved.

Kindheitserinnerungen werden wach. I also had this Puzzle as a Child but in Plastik. 😁👌😎👏

I have an app on my phone that has a square puzzle like this. You can go from 3x3 to 7x7 and on the 4x4 i can solve it in around 30 seconds. Sometimes I get lucky and solve it in under 30 seconds, but it's not that hard to solve. It did take me years to figure out a fast algorithm to solve the shuffled puzzles and at some point I figured out how to put it in a specific layout assuming it's solvable.
I did these with pictures as a kid and I used to be really good at them because I was shown the the trick of how to reorder stuff, but it's been so long I forgot the trick..hopefully I remember after seeing you do it 👀
When I was young I had one of these made of plastic that had a picture you have to solve. I think they used to come in Christmas crackers
My parents bought me this puzzle when I was about ten years old. It was probably my first puzzle, and I quickly learned a few techniques to solve it. It's great fun, and a pretty simply but well-made gift for any child or adult.
I have a different approach at the end. I arrange pieces by rows too, but when it comes to last two rows, I start arranging them by columns. 9+13, then 10+14 and then it's basically done.
Endless combinations, isn't it like 16! ? I mean that's a huge number but not endless/infinity. ^_^
Over the years I've discovered there's multiple ways to solve the puzzle. You can move the last pieces in a row the way Mr. Puzzle did, but I have a different way of getting them in order.
there is 16! possible combinations which is equal to:
16!=1*2*3*4...15*16=20922789900000
Wow, I have that same one. I bought it over a decade ago, and it's still as good as new with case and booklet. I am surprised they still make the exact same one. Mine has brighter red for the red tiles, and the white tiles are more ivory. Of course that could be age, and/or the camera not picking up the right colors. Fantastic puzzle toy.
always loved to solve this puzzle on computer, stucking on the last row , then trying to solve it😄. but the sound feels more satisfying. Really cool 👍👍
got reminded of the old school windows7 gadget thanks mr puzzle
Hey Mr Puzzle, what is the hardest puzzle you’ve faced? Obviously not including women 😝
I do love a good slider puzzle and most are solvable after learning the sliding patterns & methods and most are a good time waster.
This is a well made piece with a nice weight to it and has very satisfying AMSR sounds to it compared to the plastic models that only really have the benefits images going for them. Mic it up and get those sliding and clicking sounds moving about.
I am very sorry to say this but: i absolutely love your channel and your works but the music in background sometimes is loud and
a little annoying.
It would be nice if you let the music play on the first part of the video and turn it off completely (or low a lot the volume) after the spoilerbreak.
I play a lot of hidden object games and this puzzle is almost guaranteed to be in every game. It’s a fun classic puzzle. I didn’t realize it had such a long history
The way you solved the last two rows is too complicated :P. I ussually did it like solving 3 and 4 but vertically instead horizontally
I had horrible plastic versions of this, pretty much disposable.... But classic puzzle,,,
i remember this puzzle from my PC
Nice 😃😃😃
I have this exact puzzle, it used to be my Nan’s. It’s fun to do and doesn’t really get boring.
I have this exact puzzle somewhere in my home, though it has likely fallen apart by now.
I love puzzles but I have no head for sliding puzzles. They frustrate the 'essential tremor' in me.
I had a metal one as a kid and just got another. If you get used to this on a tablet get ready to go slow on the metal one. The tiles don't slide anywhere close as smooth as they do on a tablet. Duh. I may be ruined!👍👍👍
I have not found any software versions of this puzzle that allows you to slide two or three tiles at a time. With these metal or plastic versions the tiles may be slid two or thee at a time therefore reducing your score at the end and solving the puzzle faster.. I have had to use a 3inOne oil to lubricate the base for the tiles to slide easier.
the way you solve the last row is slightly inefficient, i personally put 9 and 10 on the side and 11 and 12 on the other side then i just cycle the 3 in the middle
I have the same puzzle!
I've finally found a different way to solve it. I have my own way to solve it but have found out over time that it has multiple ways of solving it.
Mr.Passle! do another giraffe with only two pieces but impossible!
I learnt how to do these very quickly by doing puzzle boxes on Runescape
That is bear good please let the know go. Opologize for not good inglish. I'm Poland.
To explain easy things is not easy. After dozen of attempt I finally find best one. This is it. Thanks.
This reminds me of my childhood...but mine was 3x3 and made out of plastic
Too bad the music was too loud to hear the way the puzzle sounds as you move the pieces. Music is really unnecessary.
Love the video, but the music is sooooo irritating that I can hardly stand to watch it.
I’ve had that puzzle for a few years, and I have become a pro at solving it.
Very beautiful puzzle, the colors chosen and the finish are very tasteful.
Can you solve a rubixcube? :P
PS: Glückwunsch für die 500k 😁
Den 3x3 habe ich noch nicht geschafft.
I want one, and it's only $17 with shipping and tax?! Bought.
Rubics did rubics 15 slide, next generation of this basic version
That does look like a cool game to play when you get bored... keep the mind thinking.
When i was 4 (as far as my memory can go back) i had one of these and then i never saw it again until now
What is the music for this video? It sounds so familiar but i cant place it...
Window 7 가젯 중에 그림 퍼즐이 있었는데 저거였구나!
Great puzzle
