Casse tête en metal de la série Cast Puzzle et de difficulté niveau 4 (sur une échelle de 6).
Description éditeur en anglais:
Here is a challenging maze.
At first glance, the two pieces have simple concave and convex angles on their flat surfaces.
However, when the two pieces intertwine, they take the shape of a 3D maze.
You must twist and turn them around.
If you rush without thinking, you will come to a dead end.
Be careful as you may end up going around in circles.
Designd by Vesa Timonen from Finland.
