  • Patent number: 5676374
    Abstract: The game disclosed includes a movable staircase assembly that moves characters from one location on the staircase assembly to another. A spinner directs a player to place a character on the staircase at a specific location, to skip a turn, or remove an opposing player's character from the staircase. The winner is the first player to have all of her characters reach the end of the staircase. The staircase includes stationary and movable components that serially move the characters from one step to the next with a reciprocating motion of the movable component relative to the stationary component. A gear mesh and cam converts the rotary motion of a battery-operated motor to a reciprocating motion in the movable component.
