Hi Twisty Puzzles fans,

Uncanny Mixup combines concepts from the Uncanny Cube and the Mixup Cube. This combination was suggested by Bram Cohen, who also came up with the Uncanny Cube idea. Around the same time, this "unbandaged" Uncanny Cube was also suggested by Vladimir Yaroslavskiy, inspired by the Bermuda Cubes. And also Khaled Habbab suggested unbandaging after playing with his Uncanny Cube sample.

The development of this puzzle took me three rounds of prototyping. The first version was unstable. I added floating anchors (lengthening pieces towards the middle) to keep the pieces upright. The second version worked better, but some moves were blocked. The third prototype, the one demonstrated on the video, works perfectly.

Watch the YouTube video.
Buy the puzzle at my Shapeways Shop.

Check out the photos below.

Enjoy!

Oskar

Another one for the solvers! Great challenge!

Amazing. Would you mind posting a picture of the core? Or is it just a 3*3 core?

Bermuda cubes? Pah! Take that DaYan. Another great puzzle from the Master.

Can you add upload an image of the puzzle in the state of 1:25 in the video?

So it's like an Uncanny Cube/Bermuda Venus with 10 turning axes (8 axes on middle layer + top & bottom face)? Would probably be very fun to solve... maybe I'll find the money somewhere. :D
Edit: yes, with 10 axes I meaned the axes it mathematically has.

Done.

Yes and no. Yes, that is what this puzzle plays like. No, that is not the correct number of axes. The puzzle has an Uncanny Cube inside, of which only the ten corners and eight triangular centers are visible outside. A set of square pieces of three types (center-like, edge-like and corner-like) hang between those. And a whole bunch of small hidden pieces with floating anchors keep everything in place.

I asked "how many screws does this Uncanny Mixup have?" in the YouTube video. Most YouTube fans guessed wrong. However, the question is not that difficult for true twisty puzzles fans.

I'm guessing 4 machine screws.

Plus 12 blind rivets, 45 threaded nails, 3 blue paper clips, 6 articulated hinges, and a partridge in a pear tree.

That is correct. Uncanny Cube has five screws, one for each center (2x triangle + 3x square).Uncanny Mixup has one triangle fuse to the sphere core, hence one screw less.

It was well worth the effort. A truly great puzzle. I wonder if this is suitable for mass production or if the geometry wouldn't work well with injection molding.

The geometry is not the problem. This one has too many tiny pieces.It is rather cumbersome to assemble, even for small Chinese hands.

So, do you have a "small" army of oriental slaves at your disposal, or do you have freakishly small digits?

Very nice!

Will we be seeing a Canny Unmixup Cube soon too? :lol:

Only if somebody orders one. It is just a different mix of the same pieces.

Ok... so we now have 3 puzzles which look identical.

(A) The Uncanny Mixup seen in this thread
(B) The Uncanny Cube
(C) The DaYan-Bermuda Cube Venus

Image

Actually it looks like the Venus cube is a shape variation of the other two where its red face (as seen in the pic above) has been rotated by 135 degrees. So for the sake of this discussion lets assume there was a Bermuda Cube where this shape variation had been taken out and it was truely identical to the other two. Let's call it Venus#2.

(1) Do any of the other Bermuda Cubes appear bandaged such that you could apply this same process to them? Not sure about the ones which have adjacent trangular face centers but I would think there could be a Mercury Mixup puzzle. If yes, could these other puzzles be made from the same parts used in the Uncanny Mixup? In the case of the Mercury Mixup you might need to rotate the white face by 45 degrees.

(2) I believe in the sloved state the Uncanny Mixup has all the moves available on both the Uncanny Cube and the Venus#2. Correct me if I'm wrong. As such both the Uncanny Cube and Venus#2 appear bandaged. Knowing bandaged puzzles can be harder to solve then unbandaged puzzles I wonder how these 3 puzzles would rank from hardest to easiest.

(3) Has anyone calcuated the number of permutations for any of these 3 puzzles? Does the Uncanny Cube have more states then the others? I could potentially see that the states it reaches after a move which is blocked of one of the others may still be reachable on the others, but would just require more moves.

(4) Back to the first question. If there are other flavors (planets if you will) of the Uncanny Mixup how many are there? Not counting puzzles which just differ by shape variations induced by partial face rotations. Assuming they all share the same pieces... Oskar could you offer a "kit" which had enough pieces to make any one of them.
