Designed to challenge the mind, this puzzle ball features two rotating hemispheres and two sets of colored tiles that move within canals on the sphere. Once the tiles are scrambled, the goal is to get them back into their original configuration, with one white tile at the north pole and the other at the south. There are several different strategies and approaches for one or more players.

This kit is designed for children and adults who wish to build and solve the SphereXYZ. The pieces can be assembled in any way, and once snapped in, the puzzle is ready to be solved, which is done by rotating the hemispheres and moving the scrambled tiles along the canals until each hemisphere hosts the complete collection of one of the tile colors and the two white tiles are positioned at either pole. SphereXYZ takes about 10 minutes to snap together. "It's the first-ever 'build it, solve it' puzzle," Lori Powers, co-founder of LA1Products, told TDmonthly.  Launch date: November 2009.
