The plaything is used as a 3-dimensional logical means of puzzle type for the entertainment of children and adults. It includes a shot (7) and a casing on which a labyrinth (maze) of numerous tubular grooves (2) of arbitrary directions is fitted. The casing is in the form of a hallow non-transparent sphere (1) in the zone of the poles of which, opposite to each other, an inlet (21) and outlet (22) of the tubular grooves (2) labyrinth are fomed. Inlet (21) and outlet (22) are funnel-type and in the zone of their openings there is a pair of metal terminals (31 & 32) electrically connected to the respective terminals of an electric battery (4) and sound converter (5). Tubular grooves (2) have bifurcations in some places in one of which metal terminals (8) are fitted electrically connected to light emitting diods (9), electric batter (4) and the sound conveter (5). Terminals (31 & 32) and converters (5) are fitted in seats immediately under the surface of the sphere (1). (11) 49
