Claim 0:
1. A cubic puzzle capable of changing its entire body into a cubic block shape with a plurality of pieces, the cubic puzzle comprising:
a core member arranged at a center side of the cubic puzzle;
the plurality of pieces each having a square facet configuring a part of six outside faces formed resulting from change into the block shape, said pieces being arranged side by side so as to cover the whole or approximately whole circumference of said core member, while being in a state where a grid-like pattern displayed on each outside face is obtained with a plurality of facets;
a support mechanism for supporting said plurality of pieces to said core member so that said pieces are rotatable centering around three rotation axes being three virtual linear axes perpendicularly or approximately perpendicularly intersecting one another at the center of said core member; and
a controller including an actuator for rotationally driving said pieces and performing control of the actuator;
wherein a rotating unit including said plurality of pieces arranged in a square annular shape circumferentially around each rotation axis is constituted so as to be integrally rotated centering around the each rotation axis;
each of the three rotation axes is provided with a plurality of rotating units which are mutually the same in number and are arranged side by side in the axial direction of the each rotation axis;
a puzzle body including said core member, said pieces and said support mechanism is constituted so as to be subjected to change into the block shape by turning all the rotating units arranged in the axial direction of any one of the rotation axes so as to bring them into a state of being completely or approximately completely overlapped one another in the axial direction of the one rotation axis;
said puzzle body being constituted so as to, at every pattern changing operation by which said puzzle body in a state of being changed into the block shape is subjected to re-change into the block shape by turning any one of the rotating units in said puzzle body in one direction centering around any one of the rotation axes, allow a combination of the plurality of pieces constituting the other rotating units rotated centering around the rotation axes other than the one rotation axis to be changed;
each facet has a predetermined character, color or pattern, or alternatively, a combination thereof which is displayed in a fixed fashion thereon so as to allow a part of a display pattern composed of display contents on the six outside faces of said puzzle body having been changed into said block shape to be changed at every pattern changing operation;
said controller includes a pattern identifying means for identifying said display pattern and a start state detecting means for detecting a predetermined start state; and
said controller is constituted so as to automatically change the display pattern to a reference pattern being a predetermined reference display pattern, making it a minimum condition that a current pattern being a display pattern at that point of time when identified by said pattern identifying means is different from the reference pattern, while said start state detecting means detects said predetermined start state.
