Abstract
A top toy including a track component for supporting a wheel-type top. Each track member has a peripheral rim to cooperatively form a two-rail track. Each of the rims is configured non-circular such that the magnetic spindles of the wheel-type top move toward and away from an axis of a shaft of the track component as the top travels on the rims about the axis of the shaft.
