A track having spaced, parallel edges, including a plurality of adjacent curves facing in different directions and connections between the curves, around which a frame carrying an object, such as simulating a racing car, a greyhound, a horse, a camel or the like, is moved by gravity when the track is tipped. An inner panel has an outer contour providing the inner edge of the track, while an outer panel has an inner contour providing the outer edge of the track. The frame on which the object is mounted carries a pair of wheels engaging both the bottom and the top of the track at each side. The frame also carries a pair of circular, rotatable ball bearings mounted for rotation in the plane of the track panels and engageable alternatively with the opposed edges of the track for guiding the object around the track. The spacing between the track edges is slightly greater than the diameter of the ball bearings, to provide clearance. A lower panel supports the track panels and, in turn, has a centrally depending, circular block which is engageable with a flat top surface of a support pedestal. The support pedestal and circular block each have a central socket with a coil spring extending between the sockets to resiliently support the track but permit pivoting of the track to different successive tipped positions on the pedestal, to cause the object to move around the track by gravity.
