After the 3 and the 5 circuit labyrinths on Rubik’s Cube, only the 7 circuit is missing. Unfortunately, the usual 3x3x3 cube is too small for that. And the next category (Rubik’s Revenge) with 4x4x4 is a little too big. In order to fill all areas, you need an 8 circuit labyrinth. The well-known 7 circuit (classical) labyrinth is best suited to this, supplemented by a kind of “lap of honor”, an additional loop. It can be added at the beginning or at the end.
Here I present the labyrinth with the additional loop at the end.
First the unfolded cube with the names of the different sides:
And here Ariadne’s thread:
The path sequence is: 3-2-1-4-7-6-5-8-9. This is the sequence for the classical 7 circuit labyrinth with an additional loop, hence “9” is the center (and not “8”). The entrance to the labyrinth takes place on the 3rd circuit. It is on the front side of the cube. And the center is next to this space on the same side. This shows that all other lines are only detours. Just like in the “right” labyrinth. The beginning and the end of the line (Ariadne’s thread) are right next to each other.
It should also be noted that the path on the cube is very distorted compared to the familiar look of the labyrinth, and not as balanced as we are used to. But the essential is there, the intricate and complex, not crossing lines. It is also nice that all small cubes are occupied, there are no empty spaces.
Again, a template that can be used to build a model. Here you can see, print or download it as a PDF file.
I tried it myself and made a more or less successful cube:
In the large picture above, you can see the top, left and front sides from above. The three smaller pictures are each rotated by 90 degrees.
Here in a tilted representation:
In the large picture above, you can see the front, left and lower side from above. The three smaller pictures are rotated by 90 degrees again.
I cannot judge how difficult the twisted cube would be to solve. And whether it is enough to simply say: connect the beginning and the end with each other without crossing the line?
