Some testers dubbed this challenging puzzle a round version of Rubik's Cube. A nicely weighted ball that fits comfortably in the palms is studded with twelve holes, each outlined with a different color. Marble-sized spheres of corresponding colors peek out from eleven of the holes. The twelfth is empty so you can snap a neighboring ball into the interior in a series of moves to randomly rearrange the mini-balls. The object then is to return them to their original conformation, enjoying all the satisfying clicks along the way.
