co-joined cubes or fused cubes are not a new idea, I have seen pictures of them for years but had never actually tried one until recently. I noticed that Calvin's Puzzle had released a few of them so I thought I would get a few of them and see if people wanted them. When I received them they were really good, Calvin's Puzzle did a very good job of cleanly joining them together and they present a new challenge as the cubes being joined together in differerent ways each changes things a bit.

This was the first double cube I tried, it is joined together by flipping one edge piece and gluing it to two corner pieces so that the torpedo faces the wrong way, this allows the corners to be put in one cube and the edge to be put in the other. The turning is restricted as 2 layers on each cube cannot be turned at all and others are sometimes restricted, solving the cross and F2L on each cube required some lateral thinking and ensuring that the cross was solved on the last layer was difficult too as F moves weren't possible so the regular algorithms wouldn't work. |

The Double Cube V2 looked like it would be a bit more difficult and it kind of was, the cube is joined together in a slightly different way which makes one middle layer restricted too, two corner-edge pairs are joined together and inserted into each other. I eventually figured it out too but it required a lot of lateral thinking in how to do F2L.

I thought that the Double Cube V3 would be the most difficult, however, I soon realised it was just two cubes where oinly RUF turns were possible and I have tried cubes like that many times before so this was actually the easiest of the 3 of them, I am a bit disappointed that they only come in black as I see no reason why stickerless is not possible.
