Abstract
Abstract A multi-surface pinball machine, which may be played by one or more players. The surfaces connect at an apex, and one or more players stand at the outer ends of each surface. An automatic flipper actuator is provided for play of the game with the number of players less than the number of surfaces. The machine can operatively be switched from the multi-player mode to as little as a single player mode. In such a mode, software controls the flippers of the missing players. Thus, the multi-surface table allows for either simultaneous competitive play by two or more players, or play by as little as one player competing against the machine.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
96 words
A pinball game, including a playing surface and a ball, to be played by at least one player, comprising: a flipper element including a contact surface, the flipper element movably mounted relative to the playing surface; a sensor operatively connected to the flipper element to detect impact with the contact surface; and an automatic flipper actuating mechanism, coupled to the flipper element, for automatically actuating the flipper element upon impact of the ball with the contact surface; wherein the flipper element remains in contact with the ball as the flipper element moves across the playing surface.
Claim 2
Dependent Claim
96 words
A pinball game, including a playing surface and a ball, to be played by at least one player, comprising: a flipper element including a contact surface, the flipper element movably mounted relative to the playing surface; a sensor operatively connected to the flipper element to detect impact with the contact surface; and an automatic flipper actuating mechanism, coupled to the flipper element, for automatically actuating the flipper element upon impact of the ball with the contact surface; wherein the flipper element remains in contact with the ball as the flipper element moves across the playing surface.
Claim 3
Dependent Claim
34 words
The pinball game defined in claim 1, further comprising a scoring mechanism operatively connected to the sensor such that points are allocated to the player upon impact of the ball with the contact surface.
Claim 4
Dependent Claim
41 words
The pinball game defined in claim 1, further comprising a scoring mechanism operatively connected to the sensor such that points are not allocated to the player if the flipper element is actuated upon impact of the ball with the contact surface.
Claim 5
Dependent Claim
40 words
The pinball game defined in claim 1, further comprising a plurality of flipper elements, wherein a first player operates a first set of the flipper elements and the automatic flipper actuating mechanism operates a second set of the flipper elements.
Claim 6
Dependent Claim
38 words
The pinball game defined in claim 1, further comprising a plurality of flipper elements, wherein a first player operates a first set of the flipper elements and a second player operates a second set of the flipper elements.
Claim 7
Dependent Claim
50 words
The pinball game defined in claim 1, further comprising a control mechanism for use by a player to actuate the flipper, means for selectively switching the actuation of the flipper between the automatic flipper actuating mechanism and the control mechanism thereby switching between a single-player and a multi-player mode. 1
Claim 8
Dependent Claim
18 words
The pinball game defined in claim 1, wherein the automatic flipper actuating mechanism comprises a microprocessor and software.
Claim 9
Dependent Claim
226 words
A pinball game, including a ball, to be played by at least one player, comprising: at least one playing surface, upon which the ball travels; a plurality of targets disposed on the at least one playing surface and to which a point value is assigned; a first set of flipper elements operable by a first player and including a contact surface, the flipper elements movably mounted relative to the at least one playing surface; a second set of flipper elements, including a contact surface, selectively operable between an automatic flipper actuating mechanism and a second player, the flipper elements movably mounted relative to the at least one playing surface; a sensor operatively connected to the flipper elements to detect impact with the contact surface; and a scoring mechanism operatively connected to the sensor for recording the points accumulated by a first player after the ball contacts a flipper element associated with the first player until the ball contacts a flipper element associated with the automatic flipper actuating mechanism, and the points accumulated by the automatic flipper control mechanism after the ball contacts a flipper element associated with the automatic flipper actuating mechanism until the ball contacts a flipper element associated with the first player; wherein the sensor remains in continuous contact with the ball as the flipper element moves across the at least one playing surface.
Claim 10
Dependent Claim
226 words
A pinball game, including a ball, to be played by at least one player, comprising: at least one playing surface, upon which the ball travels; a plurality of targets disposed on the at least one playing surface and to which a point value is assigned; a first set of flipper elements operable by a first player and including a contact surface, the flipper elements movably mounted relative to the at least one playing surface; a second set of flipper elements, including a contact surface, selectively operable between an automatic flipper actuating mechanism and a second player, the flipper elements movably mounted relative to the at least one playing surface; a sensor operatively connected to the flipper elements to detect impact with the contact surface; and a scoring mechanism operatively connected to the sensor for recording the points accumulated by a first player after the ball contacts a flipper element associated with the first player until the ball contacts a flipper element associated with the automatic flipper actuating mechanism, and the points accumulated by the automatic flipper control mechanism after the ball contacts a flipper element associated with the automatic flipper actuating mechanism until the ball contacts a flipper element associated with the first player; wherein the sensor remains in continuous contact with the ball as the flipper element moves across the at least one playing surface.
Claim 11
Dependent Claim

55 words
The pinball game defined in claim 8, wherein at least one of the flippers in both the first and second sets of flipper elements comprises an offensive flipper disposed on a first playing surface associated with the first player, and a second playing surface associated with the automatic flipper actuating mechanism or the second player.
Claim 14
Dependent Claim

A method for automatically controlling a flipper element in a pinball game, including a ball, comprising the steps of: detecting impact between the ball and a first flipper element; automatically engaging the first flipper element to propel the ball away from the first flipper element, the flipper element all the while maintaining contact with the ball from the time of impact to the time 1 of release; and biasing a scoring mechanism to accumulate all subsequently scored points to a score element associated with the first flipper element until a second flipper element not associated with the automatically controlled flipper element engages the ball.
Claim 19
Independent Claim
104 words
A method for automatically controlling a flipper element in a pinball game, including a ball, comprising the steps of: detecting impact between the ball and a first flipper element; automatically engaging the first flipper element to propel the ball away from the first flipper element, the flipper element all the while maintaining contact with the ball from the time of impact to the time 1 of release; and biasing a scoring mechanism to accumulate all subsequently scored points to a score element associated with the first flipper element until a second flipper element not associated with the automatically controlled flipper element engages the ball.
