Award-winning 3-D spherical puzzle that both challenges and inspires. Stunningly beautiful and intellectually riveting. To graduate from one layer to the next, users must find the correct position for each piece to progressively build spheres within spheres. The unraveling discovery happens when taking the puzzle apart and the true mental challenge occurs when putting the puzzle spheres back together.
