Pachinko stand-alone and bonusing game

Image Number 4 for United States Patent #6340158.

A Pachinko bonus game system for an underlying game machine. The Pachinko bonus game has a playing field with a plurality of rows of pegs. A ball is launched onto the playing field by a launch mechanism when an initiate condition occurs during play of the underlying game. A row of lanes are provided on the playing field. The ball, after traversing among the pegs on the playing field, eventually travels through one of the lanes. At each lane is randomly displayed a bonus payoff value. The lane the ball travels through senses the presence of the ball and the value displayed for that lane is added to the credit meter in the underlying game. The bonus payoff values are randomly changed from game to game which eliminates any mechanical bias present in the Pachinko game. A stand-alone Pachinko game as well as using a Pachinko game as a coin dispenser is also provided.
