Abstract
Abstract A demolition derby game wherein vehicles are positioned on a gameboard and driven by means of manually operated magnetic manipulators positioned beneath the gameboard. There are plural such vehicles, one vehicle operated by each player. Each vehicle includes a plurality of identical removable elements, such removable elements being removable upon impact with another vehicle. The removable elements fit into grooves in the vehicle and are positioned about opposite sides of shafts with spring elements and disc portions at their ends. The impact of a vehicle with another vehicle will cause a shaft to move and force one of the removable elements out of its groove and onto the playing surface.
