Abstract
Abstract The player controlled play feature consists of an area on or associated with the playfield which is partially confined by a plurality of bumpers. At least one target is provided in this area and an entrance is provided such that a pinball can enter the area defined by the bumpers. Located in the defined area and supported below the surface thereof are a plurality of electromagnets energized by activation of player controlled buttons mounted on the game's cabinet. The game player can selectively activate the electromagnets to redirect the pinball and propel it toward the provided targets.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
172 words
A pinball game comprising: a) an inclined playfield; b) a ferromagnetic ball supported on the playfield; c) a portion of the playfield being at least partially enclosed by bumper means; d) at least one target located in said enclosed portion of the playfield to be contacted by said ball; e) means for allowing the ball to enter the enclosed portion; f) means for allowing the ball to exit the enclosed portion; g) at least one electromagnetic means in operative relation to the enclosed section for propelling the ball over the playfield solely by means of the magnetic field created when the electromagnet is energized, said at least one electromagnetic means being located adjacent said means for allowing the ball to exit such that energization of the electromagnetic means can prevent the ball from exiting the enclosed portion; and h) player controlled means for briefly energizing said at least one electromagnetic means to propel the ball over the enclosed portion whereby points are scored when the ball contacts said at least one target.
Claim 2
Dependent Claim
172 words
A pinball game comprising: a) an inclined playfield; b) a ferromagnetic ball supported on the playfield; c) a portion of the playfield being at least partially enclosed by bumper means; d) at least one target located in said enclosed portion of the playfield to be contacted by said ball; e) means for allowing the ball to enter the enclosed portion; f) means for allowing the ball to exit the enclosed portion; g) at least one electromagnetic means in operative relation to the enclosed section for propelling the ball over the playfield solely by means of the magnetic field created when the electromagnet is energized, said at least one electromagnetic means being located adjacent said means for allowing the ball to exit such that energization of the electromagnetic means can prevent the ball from exiting the enclosed portion; and h) player controlled means for briefly energizing said at least one electromagnetic means to propel the ball over the enclosed portion whereby points are scored when the ball contacts said at least one target.
Claim 3
Dependent Claim
119 words
In combination: a play feature for directing and propelling a ferromagnetic ball at a target and; an inclined playfield on which a ferromagnetic ball can roll, the combination comprising: a) a ferromagnetic ball; b) an inclined playfield a section of the playfield being at least partially enclosed by bumper means; c) targets in said section for being contacted by said ball; d) at least one electromagnetic means in operative relation to the section for propelling the ball solely by means of the magnetic field created when the electromagnetic is energized; and e) player controlled means for briefly energizing said at least one electromagnet means to propel the ball over the section whereby points are scored by contacting said targets.
Claim 4
Dependent Claim
119 words
In combination: a play feature for directing and propelling a ferromagnetic ball at a target and; an inclined playfield on which a ferromagnetic ball can roll, the combination comprising: a) a ferromagnetic ball; b) an inclined playfield a section of the playfield being at least partially enclosed by bumper means; c) targets in said section for being contacted by said ball; d) at least one electromagnetic means in operative relation to the section for propelling the ball solely by means of the magnetic field created when the electromagnetic is energized; and e) player controlled means for briefly energizing said at least one electromagnet means to propel the ball over the section whereby points are scored by contacting said targets.
Claim 5
Dependent Claim
15 words
The play feature of claim 2, wherein said section is elevated relative to said playfield.
Claim 6
Dependent Claim
17 words
The play feature of claim 2, further including a ramp for delivering the ball to the section.
Claim 7
Dependent Claim
17 words
The play feature of claim 2, further including means for allowing the pinball to exit said section.
Claim 8
Dependent Claim
105 words
A play feature for directing and propelling a ferromagnetic ball at a target on a playfield of an amusement game comprising: a) a ferromagnetic ball; b) an electromagnet to be disposed in operative relation to said playfield for propelling the ball solely by means of the magnetic field created when said electromagnet is energized; c) a target means for producing a signal when contacted by said ball; and d) player controlled means for briefly energizing said electromagnet when said ball is at a desired position relative to said electromagnet to control the direction of the force applied to propel the ball at said target means.
Claim 9
Dependent Claim
105 words
A play feature for directing and propelling a ferromagnetic ball at a target on a playfield of an amusement game comprising: a) a ferromagnetic ball; b) an electromagnet to be disposed in operative relation to said playfield for propelling the ball solely by means of the magnetic field created when said electromagnet is energized; c) a target means for producing a signal when contacted by said ball; and d) player controlled means for briefly energizing said electromagnet when said ball is at a desired position relative to said electromagnet to control the direction of the force applied to propel the ball at said target means.
Claim 10
Dependent Claim
44 words
The play feature according to claim 6 wherein said target means and said electromagnet are adapted to be located in a partially enclosed area associated with said playfields whereby points are scored by successfully directing the ball at said target means using said electromagnet.
Claim 11
Dependent Claim
42 words
The play feature according to claim 6, wherein said electromagnet is adapted to be located in a partially enclosed area associated with said playfield and wherein points are scored by successfully maintaining the ball within said partially enclosed area using said electromagnet.
