The goal is to build long marble tracks. On your turn you can move and/or rotate (Cuboro) elements. So that your marble track ends on an empty exit. You score points by the length (used Cuboro elements) of your track. The game is based on the cuboro system. There are different versions included. With the easy one you use only one level of the elements (on top). In the more challinging version you use tunnels as well.
