Mechanical puzzle consists a rounded heads (g1) and (g2), circular wedges(k1) and (k2) of male components (md) in the form of equal cut pieces of a hollow ball with a pressure of a hand that by a hand thrust feed in through narrow input outlets into the appropriate grooves (ž1) and (ž2) of female components (žd) of the same shape and therewith comes no touch with rounded groove bases as their input is limited to the edge (i1) and (i2) that rest onto the walls of male components (md). So as to obtain that each hemisphere on the puzzle have at the endings of the component of each pole and opposite pole of ending components at the other hemisphere, and in, that both hemispheres are enabled that, one compared to the other, axially rotate, number of male parts (md) and number of female parts (žd) is the same one and only odd number, from one different.
