Fushed 3x3x3 a bit difficult, but not very hard if you can solve a 3x3x3




Fushed 4x4x4 very difficult to solve because most 4x4x4 knowf method will not work.

They look great!! The 4x4x4 fused and 5x5x5 fused are harder because you dont use typical methods to solve them. I have a method for solving the 5x5x5 fused which will work for the 4x4x4 too. Has anyone else solved the large fused cubes?

I know that is not a fused, but I was able to solve a Siamese 4x4x4 after messing with it for a while. I haven't tried a 5x5x5 though.

Which is harder? siamese or fused?
Not which has more combinations- which is harder

Since you can do any permutation with the three sides on a fused cube. All possible combination are possible. In fact you can solve the normal cube only using three sides like FUR.

On a siamese cube the corners can not be switch in all possible combinations. So less possibilities.

A 4x4x4 fused cube is very hard to solve, more difficult a 5x5x5 since you do not have the center as orientation

The corners can always give away how to solve an even order cube. As such, I think that the extra pieces on a 5x5x5 cube make it harder in theory. However, the only really hard thing about the 5x5x5 fused was the centre pieces which share an edge with the middle piece. These pieces are missing from the 4x4x4 fused. So I believe that the 4x4x4 fused is much easier. You can just do a couple of moves and then turn it into a 2x2x2 cube. 5x5x5 fused is much harder.

In answer to your question Tyler, Ill try and do some siamese cubes and see which I think are harder.

I have both the fused versions a 4x4x4 and a 5x5x5. The 5x5x5 is just more work. But the 4x4x4 is more difficult. You may simulate this with a normal 4x4x4 and tape a 2x2x2. Just try it, and let me know!

The 3x3x3 is just different not that so difficult, you just need a lot of turns to do the moves needed. For the last layer I use 1 algoritme to put the corners in place, 1 algortime to turn the cornes. 1 algoritme to flip edges and 1 algortime to switch 3 edges. Only the edge algoritmes I had to find, that took me 5 min.

The 4x4x4 fused needs a new odd permutation algoritme, this one is hard to do on a fushed cube! I am looking in to it to do this in about 20 turns.

It took about 5 minutes to solve a 4x4x4 fused. i just matched up the edge pieces to the corners using single slice twists. then i matched up the centre pieces to the corners using an algorithm of about 8 moves (usually fixed 2 or sometimes 3 pieces at a time). after that, it has been reduced to a 2x2x2 cube. that only takes a few seconds to solve.

the thing that makes a 5x5x5 fused harder is the centre pieces which share an edge with the middle piece. these arent on the 4x4x4 fused. also, following roughly the same method as utlined above, it reduces to a 3x3x3 fused so the last stage takes longer as well. so it is much more difficult. do you have an easier way to solve a 5x5x5 fused?

Yes that must work for the 4x4x4! I used now a method based for the normal 4x4x4 (make a 3x3x3), this will solve a normal 4x4x4 in 3 min for me. Maybe your method will also help to get my solve time down for the normal 4x4x4.

Thanks!

I havent tried out the siamese versions. Are they hard?

Ive tried it for a normal 4x4x4 (turn it into a 2x2x2), but it seemed to take a bit longer for me. The one big benefit is that when it is finished, there will never be any parity problem to deal with.

If you can solve a regular you can solve a siamese if you work/long enough. The thing that I have always been a little disappointed in with these siamese cubes is that the pieces to move between each other. When I first saw them years ago, I thought that they did. Hmmm seems like I should be able to do that.

i think the cubies from each cube should be able to mingle with the cubies from the other cube. that would really be hard...
