15-Puzzle from QiYi is SO good - Unboxing

[@samueltaylor6421]

For speedsolving square tile puzzles, the most popular high-level method is the "fringe" method. You solve the top and left layers at the same time (1,2,3,4,5,9,13), which would reduce a 15-puzzle to an 8-puzzle in the bottom-right corner. Then you solve the top and left layers of the "psuedo" 8-puzzle in the bottom-right corner (6,7,8,10,14), and then you solve the 3-puzzle, which is trivial. Ben1996123 has some insanely fast solves on his channel.

Every time when you finish with the puzzle, put a thin strip of paper or thread under the blank piece, so that you could remove the blank tile easily next time.

[@dphdmn]

idk, i just leave it empty

[@curiousNic]

I used to love these when I was a kid and still have my old one with 31 numbers somewhere in a box. Yours look much nicer though.

[@ShadowCooper77]

SAME but i had a picture puzzle

[@AlfredSpeedcuber]

Yeah, you’re really right! 15 puzzles are awesome. I remember myself when I was a kid, I bought many dollar store 15 puzzles

[@vj7248]

i most def played a tiny mini 15 puzzle as a kid. having them be so tiny and of course no magnets meant it would fall apart easily. im really digging this bigger magnetic design i think i will cop one

[@NowUndefined]

Great info about these! I'm looking forward to the next video

[@dphdmn]

15 puzzle from Qiyi is a good one, but it is too big and heavy, it takes a lot of effort and a lot of extra hand movements. In Russia, a small company has released a significantly better magnetic model recently, but so far it is still at the prototype stage.

[@dphdmn]

How is the corner cutting?

[@BambooNtertainmentIsEpic]

2032: GAN klotski that reverse cornercuts!!

[@platlim1685]

Surely

[@firecuber8302]

I have been solving the 15 puzzle for years and years , ever since I got the qiyi one I’ve been practising quite a lot . I wish that cubing comps start to include the 15 puzzle

[@dphdmn]

For years? Hey what are your results?

[@GravityKnight]

This is good training for those filler puzzles I always get stuck on in puzzle games!

[@khouzamsami5742]

That puzzle is a 3x3 shape mod where the hidden edges pop up once you scramble it

[@jesseisawesome6687]

what if using the swapping "algorithm" at 5:31 you can make a old pochman type method to solve it.

[@dphdmn]

there is a method for that, but it makes sense only for bld solve or fixing swaps in big puzzles for regular solve it's just intuitive

[@jesseisawesome6687]

dphdmn that makes sense

[@royrice8597]

My puzzle is not a Klotski and the magnets actually hinder fast movement. They have some protruding grid lines on the tray that also slows it down. Trying to dry magnetized and will put talc on tray to see if I can speed it up.👍👍👍

[@TheDrummerbadboy]

Great video! You've got me interested in getting this puzzle as well.

[@kennguyen2900]

I love the 8 puzzle because it has magnets. I like how it lines up and rarely catches.

[@evander29]

It's So Good is that your Chinese name on the box?

[@SlowerCuber]

The Chinese characters there mean "The United States"

[@yogimew]

It is the name of the country (America) and his name on the box.

[@jaagritsupercuber1341]

OMG!! How clear.

[@ConcreteAngelx3]

What! Mine didn’t come with that cool case 😩

[@ben1996123]

for 8 puzzle the fastest method is "just solve it". I don't use a real method, I just solve all of the pieces at once, usually optimal solution and almost always within a few moves of optimal

[@jenniferwu963]

Don’t you use fringe?

[@anja.k4]

@@jenniferwu963 fringe just reduces to an 8 puzzle

[@barcancostinel9672]

Seems pretty simple to solve. Did you lost interest after same solves?

[@dphdmn]

It's simple to just solve, but solving it optimally is not that simple

[@sheeb2855]

Do u play viola? I saw instruments in the background. I play viola too lol

[@khonrado8923]

Are those made of wood? I remember having these puzzles but they were cartoon characters and were made of plastics and sadly non magnetic 😑

[@yogimew]

Plastic

[@cubechemistry8853]

does it corner cut well?

[@dphdmn]

It's ok, but it has other problems

[@DavidvanDeijk]

You should check the numberphile video on the 15 puzzle

[@e-towncuber5522]

I love 15 puzzles and I’ve only been using an app but I really want these and I’ll probably get them.

[@dphdmn]

Hey, what are your results? What kind of applications do you use?

[@e-towncuber5522]

dphdmn the app is honestly really good, it times your solves as soon as you swipe, I’ve gotten 3 sec on the 8 puzzle and something like 38 on the 15 puzzle. The app is called 15 Puzzle(HD) by Yevgen Sokolov. It does sometimes get a bit weird as in one of the “tiles” will just go into a impossible position in between 2 spots and won’t move. Unless it happens on a good scramble I don’t mind, just gotta restart the app.

[@dphdmn]

@@e-towncuber5522 try 15 puzzle app from Igor Talankin, it has many good settings, and more importantly, it allows you to move puzzle with hover style (by clicking on empty spot and dragging), it's the fastest and easiest way

[@e-towncuber5522]

dphdmn sounds great I’ll try it out!

[@MilanRubiksCube97]

There is a much faster and better method for solving the 8-puzzle and the 15-puzzle. Just letting you know if you'd like to try and speedsolve them 😄

[@dphdmn]

there is no actual "method" for 15 puzzle

[@cosimocubing3820]

There is a speedcubing method for this (Leon schmitchen delegate is really good at the 15 puzzle)(he has a youtube channel)

[@miyuh197]

What KZbin channel is it?

[@lponchain]

[@royrice8597]

I just got one from Amazon. Looks identical with magnets too. But, on the top front it is total Chinese writing. No English at all. Package too. I have had tiles stick or pop out on speed solve. Rule: Don't go too fast!! 👎👍👎👍 Will try some talcum powder on tray 👍👍👍.

[@cientista3820]

There is case impossible ?

[@SpeedCubeReview]

Not is you scramble it without lifting pieces out of the puzzle.

[@deekay1306]

Fringe method exists. But it’s more a pattern than a method. You solve: 1, 2, 3, 4, 5, 9, 13, 6, 7, 8, 10, 14, 11, 12, 15.

[@OnefinityAnimationsTSF101]

I used to solve these on the Windows Vista.

[@oldscooljoe6194]

Start with 15 and go back to 1. (Put 15 where 1 normally needs to go, 14 where 2 normally needs to go 13 where 3 normally needs to go. Etc etc.) I bet you that it is impossible to do in reverse order if you dont take pieces out.

[@dphdmn]

yeah but it's easy to do if you are strating with blank 0 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 it actually makes more sense because if you are starting with 15 you are changing parity

[@moksh_sharma.0729]

👍👍👍👍👍

[@DreamerTheWolfFox]

there is a simulator online for download that is about sliding puzzles and i can give you a link if you want also there is a speedsolving method for them that is called fringe where you do the top than the left and move in like that

Hey, aren't you the guy who had 128x2 and 64x2 puzzles WRs?

[@DreamerTheWolfFox]

@@dphdmn yes. If you took it I really don't care as I shouldn't have really had them. I haven't been able to play in a while as my pc took a crap. Not willing to use my dad's anymore to use it on top of that.

[@catdadproblems]

FYI easier to scramble by removing the pieces, laying them face down or draw them from a bag randomly.

[@SpeedCubeReview]

It may be unsolvable. It would be like putting a 3x3 together at random

[@catdadproblems]

@@SpeedCubeReview try it. Easy to fix if true.

[@SpeedCubeReview]

You would need to take it apart again though. Don't scramble it this way.

[@mikevandebunt811]

When the 15 puzzle was first invented in the 1880s, the standard way to scramble was to take the pieces out of the frame and put them back in randomly. This drove people crazy because only half of the scrambles made this way can be solved (proven mathematically). This is why the little pocket sized puzzles produced in the 20th century had non removable pieces.

[@dphdmn]

that's slower anyway

[@MrPeterfranklin]

Nice
