Abstract

An interactive slot car game having a multiple lane slot car track for electrically powered slot car. The trackway has a pit lane which is positioned on the same side of the track for all cars, with a pit position for all cars, with each pit position located on the same side of the pit lane. The game has an intermediate control device which limits the control that the user has over the speed of the slot car, and can be programmed to simulate occurrences such as tire wear or fuel shortages. The intermediate control device limits car speed due to actual occurrences during racing, such as a car in another lane exiting the track, thereby creating and enforcing caution periods, as in auto racing. Light signals and aural signals are generated in response to the game conditions, occurrences during the game, or randomly generated events.

Claims
