What is the Snake Cube?
The snake cube is a chain of 27 cubelets. The cubelets are connected by
an elastic band running through the middle. There are 17 groups with two
or three cubelets shown in the drawing.
The aim of the puzzle is to arrange the chain in such a way that there
will be a 3x3x3 cube.
Ways to the Solution top
You can only solve the snake cube systematically.

First you number the pairs or triplets of cubelets from 1 to 17.
You see triplet number 1 on the left. While ordering you should always
keep the same orientation in the room.
You fix this orientation by a coordinate system with x, y and zaxis. 
You learn from a diagram how to arrange the 16 following groups. There
are also dead ends with STOP to show the structure of this puzzle.
I will explain the names of the moves by an example. "10x" means: Arrange
the 10th group in direction of
the xaxis.
If you see the simple diagram you may wonder why this puzzle is so difficult.
The reason is that you often have to go back to the last branch. It is
difficult to find this place.
There is another solution. You start at the end, but then you will have
technical problems. The middle vertical triplet is late and can be laid
properly only with difficulties.
There are two more solutions because of symmetry. You can see one of
these in a sequence of drawings.

Twelve Cubes top
I 've got this nice cube chain. I don't know the name and the manufacturer.
Obviously it is similar to the "Kibble Cube".
...... 
The shape is simple:
There are two slits turned around 90° in opposite faces of one
cube. The 12 cubes are connected by an elastic string along the centre
axes. The first and the last cube have a knot inside. 
You can give the cube chain any direction in this arrangement. If you would
have 27 cubes instead of 12, you also could lay the snake cube above.
