Marbles.
Swiss precision.

The ball rolls and rolls, rolls into long channels, rushes around tight corners, disappears in a tunnel, continues, concealed, on its way and finally appears from its hideout in a completely different place. The route taken by the ball depends entirely on the designer of the marble track - which may include children over the age of 4, who continue to discover new labyrinths even with simple constructions.
This building block system from Cuboro promotes the mathematical and geometrical imagination in a playful way; for ingenious tinkerers, this becomes a mental challenge when the additional building block sets are brought into play.
The basic form is a block of untreated beech wood, with an edge length of 5 cm and precisely worked channels and holes, which run straight or curved. The correct combination of the various elements results in tracks which run both on the surface of the blocks and in internal tunnels.
Each of the building block sets is supplied with three balls.
