A puzzle comprises at least two relatively rotatable members in contact with one another and pivoted together about an axis normal to their contact plane. Exterior surfaces of the members are formed with tracks having their entry and exit points disposed equi-angularly about said axis and equidistant therefrom in said contact plane. Accordingly relative rotation of the members in equiangular steps brings about alignment of the several tracks in different configurations. A multiplicity of movable elements substantially fill the tracks and are displaceable therealong when the tracks in the first member are aligned with those in the second. The puzzle may in its initial position have circular tracks each filled with beads of a different color or marking, the puzzle being manipulated to randomise the beads and then to return them to their original pattern or to form another intended pattern.
