ABSTRACT OF THE INVENTION A puzzle comprises a cube having translucent faces with a light source behind each face. Gravity-sensitive or orientation-sensitive switches such as mercury switches, are connected to an electronic circuit act- ing to compare the switching states and switching movements of the switches with a programmed sequence held in a memory to determine whether and which of the light sources to illuminate. In use of the puzzle the faces will light up when a predetermined sequence of rotations about three orthogonal axes are performed correctly to match the switching sequences with the stored sequence. - 1 -
