Abstract
In a ball shooting game machine, such as a pachinko game machine having winning holes, controls for permitting the player to obtain winning balls regardless of his skill, wherein the controls effect a first state disadvantageous to the player and then a second state advantageous to the player, the controls including means for detecting shot balls reaching the game board, a random number generator for generating a random number when a preselected number of balls are shot, and means for driving or controlling the winning holes to effect the advantageous state in response to the generation of a preset specific number by the random number generator, and means for maintaining or reversing the advantageous state in response to whether or how many winning balls are achieved.
Claims9
A ball-shooting game machine for playing a game by shooting balls from a ball shooter to a game zone over a game board, comprising a winning ball production control, a shot ball detection means for providing an output signal every time a predetermined number of balls is shot from said ball shooter, means for generating a random number in response to said output signal from said shot ball detection means and means for activating said winning ball production control to effect an advantageous state to a player depending upon the random number generated.
A ball-shooting game machine having a ball shooter for shooting game balls to a game zone over a game board, one or more variable winning devices capable of being driven to assume a first state disadvantageous to a player and a second state advantageous to a player regarding production of winning balls from said game balls shot from said ball shooter, and drive means for driving said variable winning device to assume said first and second states, said ball shooting game machine comprising:
- shot ball detection means for detecting game balls shot from said ball shooter;
- random number generation means for generating random numbers in response to an output signal from said shot ball detection means;
- judging means for checking said random numbers generated from said random number generation means against preselected numbers;
- and
- control means responsive to said judging means for causing said drive means to drive said variable winning devices when a random number is generated corresponding to said preselected numbers and until a predetermined number of winning balls is produced in said variable winning devices.
A ball-shooting game machine having one or more variable winning devices capable of being driven to assume a first state disadvantageous to a player and a second state advantageous to a player regarding production of winning balls from game balls shot from said ball shooter, said ball-shooting game machine comprising:
- random number generation means for generating random numbers;
- judging means for checking said random numbers generated from said random number generation means against preselected numbers;
- and
- control means responsive to said judging means for
- determining the state of said variable winning devices when a random number is generated corresponding to said preselected numbers,
- generating a state indication signal representing the determined state, and
- driving said variable winning devices according to a content of said state indication signal, said control means further compensating the content of said state indication signal in accordance with the status of said production of winning balls.
A ball-shooting game machine for playing a game by shooting balls from a ball shooter to a game zone over a game board, comprising at least one winning device within said game zone, a winning ball production control associated with said winning device sufficient to effect a first state disadvantageous to the player and a second state advantageous to said player, a shot ball detection means for producing an output signal every time a predetermined number of balls is shot from said ball shooter, means for generating a random number in response to said output signal from said shot ball detection means and control means for driving said winning ball production control depending upon the random number generated, to effect said second state advantageous to said player.
