Hello,

Yesterday, I finished trial product of normal size Bump Cube.
And I stuck silver stickers because black stickers are difficult to distinguish cross sections.
But this coloring change is made the Bump Cube to cool.
It looks like some mechanical item.

Following photos are solved shape, rotating, and scattered, comparison.
The minimum and maximum corner piece's ratio is about 1:8. And maximum height difference is about 20mm.
But size is similarly to normal Rubik's cube.

Incredibly attractive piece. A take on the design is to sticker the mix as the completed puzzle. Really nice city-style pattern when mixed.

Wonderful.
2 questions if i may:
Is every piece different and are there symmetric pieces, I mean pieces that therefore don't need to be oriented?

Looks awesome and very cool!!!! If I may ask. How durable is it? Do the center pieces on the sides have to be oriented right? What I mean is the shiny gold is the top. All around that is the sides.

can you show us a picture of the spindal and all of the pieces. i would love to see how it looks disassembled

looks awesome! keep up the good work. great idea

Yes, there is no same size pieces. All pieces size are different.
Then, there is no parity error to solve it.



Of course, it is a little more weak than normal Rubik's cube.
And sorry, the 'gold' is refrection of background.
All stickers are glossed silver only.



I'm sorry, I don't hope to contribute the inner. Because there are little artifices to be incarnated.
The minimum corner size is 9mm x 13mm x 17mm. Yes, the thickness is more thin than mini cube's piece. This is one of artifices.

That is very, very cool!

Now I understand the name: Bump Cube. It is a beautiful puzzle. Great idea.

great puzzle, but icant really tell, is it incredibly hard to solve?

so you're done with it? i'll take it, lol

welcome to the forum

Congratulations. You finally did it !

Simply fantastic!!! Genius idea!!!

It looks beautiful. I love the concept.

I find this concept absolutely amazing.
I'd love to have one of those in my bag o' tricks when someone said "Hey, I just take the stickers off"
Hand them a bump cube and smile.

could you really make a simpler version of the bump cube by just cutting off a few millimeters of the top layer of a cube, patching the holes, and then gluing the cut pieces to the bottom layer, thus creating a cube that has a skinny top all the way around, a normal middle all the way around, and then a slightly taller bottom layer all the way around. ALthough this puzzle is not identical to Hidetoshi's bump cube, it would still provide a challenge.

I'm already in the middle of trying that (but on all 3 axes), and there's a lot more to it than you think especially since saws have thickness and cubes have rounded edges.

the only thing with cutting off the top and placing on the bottom is that when you do it that way you would have to resticker it as a 6 color otherwise you can swap edges or have them oriented the wrong way and it wouldnt matter which makes the puzzle easier.

What if you cut away parts from top and added them on the bottom, than do the same thing with parts from right that go to left and then from the front to the back. That way you'd have it. Assuming you always cut off a different "amount"/length.

i thinks that the concept of this cube. but i think that every piece was individually made here. it gets to messy if you cut and paste then cut and paste.

When I show non stuck (black) Bump cube for my father, he said similar affirmation, "Hey, I can solve it so quickly !".
And after rotated, he knew the cube's mean and he said, "Oh, my god ! I can't solve..."



Of course, I think the method at first.
But I knew a few minutes later, "It (the method) can not be recognized easily."
I think to make height difference for 2mm, but 2mm is so low to recognize for blind solving.
Then I made its difference to 4mm.

Then, the lower face is needed to cut 10mm. Yes, the cut encroaches inner rail.
But if you make it easily, your idea is right, plus / minus 1mm, 3mm, 5mm.

amazing puzzle!
are you thinking of taking the advice of getting it mass produced?
i would love one

what sort of times are you getting to solve it by the way?

I've loved this puzzle since the fist pictures of it I saw rough and unfinished in nothing but black but finished and with silver stickers it has formed into a pice of modern art :}.., God I want one.

Are you planning on selling or trading for some??

Looks like you were'nt 100% exact on the size was this due to a limit in the nature of the design or was it just due to your process for making it? I ask this because it seems fairly straight forward to design one with the exact same dimensions as a regular cube.

I'm not a speed cubist, then my normal average is about 90 sec.
On the basis of it, I can solve the Bump about 120 sec.
Yes, a little slowly, because recognition and rotation is a little difficult.



Sorry, I made it only handiwork, then it becomes expensive, and needs long time to make it.
And what's more, I can make them only weekend. Because I'm working on weekdays.

Perhaps, it needs about 2 months, and price becomes about $320. The molds becomes 26 kinds, and the molds are used only once for one cube. Then it becomes so expensive.
If you don't worry about making times and price, please consult me by PM.
(Sorry, perhaps this information is needed to contribute to Marketplace, but I don't get orders public. Please overlook this information)



The size is similarly 57mm all.
Of course, I calculated to same size with vernier caliper.
The size is my little policy.

Just thought I would add this here for reference and historical purposes. There is a patent in Russia for what looks like identical puzzle. RU2011398

Aleksey, thank you for your information.
But I think, this (patented) cube has only 2 different size centers and 3 different edges and 4 different corners.
Bump cube has 6 different size centers, 12 different edges, and 8 different corners. These two cubes are not identically, are they ?

Of course, it is interest about this idea (for identify by height not color)'s foundation was thought over 10 years ago.
I'll study more about these patents.

I love that cube it is soooo nice.

Just out of curiousity, is the core a normal 3x3, or is it a keychain cube?

Thats amazing dude... I wish I had one of those... actually it proabbly would be wasted... (I wouldn't be able to figure it out, then it would end up shattered on the floor, my dog would be barking, I would be pissed, and it would just be an overall bad time lol) but seriously... that looks great

keep up the good work!

It operates and functions like a normal rubiks cube, it will slow down your solving time because its shape and size recognition vs colors.

Excellent puzzle, very weighty too!

It's not made from normal 3x3.
But core cube is secret.
It's came out that above informations. X-)
