I wanted to make a Siamese cube but was stumped by the amount of variations people have made. I know most of them are basically the same, but which one would you recommend? Please answer the poll and leave reasons/comments in the reply section!
Sorry for the bad photo editing!

They're each different to solve, and each requires a different process to make.
3 and 5 are easiest to make, since they just require gluing some things together.
4 isn't very interesting to solve, since you can only move two sides of each puzzle.

I voted for #1. It's the classic Siamese design. Second choice goes to #2, the Fused Cubes.

I never did solve my own Siamese cubes... they're quite tricky!

Ha ha, there is only ONE Siamese Cubes.
