How does the ball get from the start to the finish when, for example, only 4 height blocks, 3 curves, and 2 tracks are available for building the course? 30 task cards specify the starting and finishing points of the course to be built. If the ball rolls from the start to the finish and all parts are used, the puzzle is solved. Hexagonal base plates that can be arranged variably allow for a challenging and varied puzzle experience with the interactive marble run system.
