Controllable response systems for providing remote control over one or more toy objects, such as a miniature toy vehicle, on a playing surface. A linkage mechanism beneath the playing surface has an end which is accessible to an operator and is used to manipulate another end, beneath the surface, which is magnetically coupled to the object being controlled. The linkage mechanism is adjustable to control the relationship between the area of movement of the end accessible to an operator and the area of the playing surface over which the toy object is moved.
