A circular mosaic puzzle for retaining a puzzle design that is adjustable between ordered and disordered configurations. Plural circular mosaic substructures, each with a display surface, a central section, and four peripheral sections, are rotatably retained relative to a frame. Adjacent circular mosaic substructures have overlapping circumferences. Each peripheral section has opposed convex arcuate surfaces, and each central section has four concave arcuate surfaces for receiving one or more peripheral sections. Concentric actuation knobs can be retained relative to reverse surfaces of the substructures. A receiving track in the frame rotatably receives the circular mosaic substructures. The receiving track corresponds in shape and size to the shape and size of the overlapping circular mosaic substructures. The track can be a depressed formation within the frame that is laterally bounded by the border structure. Correspondingly disposed apertures in the track permit passage of hubs to permit manipulation of the substructures.
