Cuboro and Cugolino Marble Runs, created by Swiss inventor Matthias Etter, represent the pinnacle of marble run toys.  With scores of different kinds of blocks, players create their own marble runs, then test and refine their creations.  The fascination of this kinetic system holds the attention and builds spatial and creative skills.  And with many supplementary sets, the system – and the possibilities – can keep on growing for years.  The Cuboro system truly is “the marble run for a lifetime.”
