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.

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.
