The application and the sense behind it
The goal of Marble Run is to build the longest marble run in the world. Every player can build his own little
marble run, also called a “track.” After saving this track, it will be appended to the existing tracks, forming a
big, collaborative marble run.
A track is built with pre-defined bricks that the player can rotate and place freely on the grid. To get an idea
of how it looks, see Figure 4-2.
