Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game machine such as a pachinko machine.

[0002]

2. Description of the Related Art Conventionally, when a combination of big hit symbols is displayed on a symbol display device, a big hit game state is established and a variable winning device is set in a predetermined mode (for example, until a predetermined time elapses, or a predetermined number of prizes are won). Until the ball occurs)
Based on the fact that a winning ball has won a continuous winning opening (also referred to as a V winning opening) formed in the variable winning device during the opening, a continuation right to reserve the next opening of the variable winning device is established. A large number of pachinko machines have been provided on the market that allow the continuation right to be established a predetermined number of times and repeatedly open the variable winning device in a short time. In such pachinko machines, those in which the probability that the combination of big hit symbols is displayed are dominant have been dominant, but in recent years, those that change the probability have been provided.

[0003]

In a pachinko machine in which such a probability is changed, one or three predetermined combinations of jackpot symbols are selected from among a plurality of combinations of jackpot symbols. Was changed to a high probability when was displayed, and the occurrence cycle of the next big hit gaming state was shortened to attract the interest of the player, but such a change condition is greater than the appearance probability of the big hit symbol At a low probability, and the probability does not change unless a considerable amount of time has passed since the opening of the store. Was. That is, when the power was turned on, the game was always in the normal game state in which all information was reset. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a gaming machine in which a predetermined gaming state is maintained even when power is turned on.

[0004]

In order to achieve the above object, according to the present invention, a predetermined game condition can be switched between a normal game mode and a plurality of special game modes having a higher game value. The gaming machine is characterized by comprising a storage means for storing predetermined special game-related data used for game control so that a special game state other than the normal game state can be maintained when the power is turned on. In this case, a variable display device that variably displays identification information when a predetermined start condition is satisfied is provided, and when the final display result indicates specific identification information, the player is notified of a predetermined special game state of the plurality of types. Preferably, it is possible that the storage means stores data relating to the specific identification information.

[0005]

Since it is possible to maintain a specific game state other than the normal game state when the power is turned on, it is possible to reduce the possibility that the interest of the game is reduced when the power is turned on again after the power is turned off. Thereby, it is possible to suppress the possibility that the player will be disadvantageous at least when the power is turned on. Further, in a gaming machine in which the special gaming state is caused by the variable display of the variable display device,
Even when the power is turned on, the game can be placed in a special game state, and it is possible to prevent a decrease in the interest of the game at the time of opening a game hall or turning on the power again during business hours.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. First, with reference to FIG. 5, a description will be given of an entire configuration of a gaming board 1 of a pachinko machine provided with a variable winning device 20 including a symbol display device 25 according to the embodiment. In FIG. 5, as is well known, a guide rail 2 for guiding a hit ball is planted in a substantially circular shape on a game board 1, and a range surrounded by the guide rail 2 constitutes a game area 3 in which the hit ball falls. are doing.

[0007] A variable winning device 20 including a symbol display device 25 as a variable display device is disposed substantially at the center of the game area 3, and three starting winning ports 4 a to 4 c are provided below the variable winning device 20 in the horizontal direction. It is attached to. In addition, between the variable winning device 20 and the central starting winning port 4a, a passing port 5 through which a hit ball falling from a later-described falling port 39 of the variable winning device 20 passes is disposed. In addition, the game area 3
In addition to the parts described above, winning ports 6a, 6b, 7a, 7
b, 8a, 8b, windmills 9a, 9b with lamps, windmill 10a
10 to 10d, and the big hit lamps 11a and 11b are arranged at symmetric positions with respect to the vertical center line, respectively. Further, the lowermost portion of the game area 3 is provided with the above-described winning opening and an out opening 12 for receiving a hit ball which has not won the winning device. Of the above-mentioned parts, the winning lamps 7a, 7b and the winning holes 8a, 8b have built-in operation lamps 13a, 13b, 14a, 14b which blink or operate when a big hit or the symbol display device 25 changes. The starting winning ports 4a to 4c have built-in starting winning ball detection switches 15a to 15c. The windmills with lamps 9a and 9b have the same function as the above-described operation lamp.

The variable winning device 20 provided substantially at the center of the game area 3 has a mounting board 21 mounted on the surface of the game board 1, and a normal winning opening 22 is formed at the top of the mounting board 21. Have been. The hit ball that has won the winning opening 22 is guided to the back of the gaming board 1 and is processed as a normal winning ball. In addition, below the winning opening 22, a rectangular hitting ball entrance 23 is opened and the hitting ball entrance 23 is formed.
A guide projection 24 is provided along the lower edge of the projection. For this reason, the hit ball that has flown from the left and right sides of the game area 3 is received by the guide protrusion 24 and is taken into the hit ball entrance 23. The hit ball taken into the hit ball entrance 23 passes through the side of the variable winning device 20 and is discharged again to the front side of the game board 1 from the drop hole 26 formed at the lower portion of the variable winning device 20. I have.

The above-mentioned guide projection 24 is projected substantially in a rectangular shape except for the lower portion, and a symbol display device 25 is provided so as to be surrounded by the guide projection 24. In the present embodiment, the symbol display device 25 is configured by three dot matrix LEDs, and each dot matrix LED configures 15 symbols (for example, a symbol).
(Numbers from 0 to 9 and English characters from A to E) can be displayed. And the starting winning ports 4a to 4c
When the hit ball wins any of the above, the dot matrix LED of the symbol display device 25 starts scrolling fluctuation at a speed that cannot be visually recognized by the player, and the fluctuation display is stopped when a predetermined time (for example, 5 seconds) elapses. The three symbols are stopped and displayed. When the combination of symbols stopped and displayed is a combination of big hit symbols, a big hit game state, which is one of the special game states, is set. The combination of big hit symbols is a case where the same symbol is displayed on three dot matrix LEDs, and therefore, there are 15 big hit symbol combinations. Then, when the combination of the predetermined big hit symbols (for example, the 3rd, 7th, 9th, etc.) becomes a predetermined big hit symbol combination during the normal game out of the 15 big hit symbol combinations, Is changed and set to a high probability (for example, 1/25). The gaming state set with such a high probability is one of the special gaming states. Note that the normal probability before being changed to the high probability (hereinafter, referred to as the low probability) is, for example, 1/2.
It is set to 50.

[0010] When the big hitting game state is reached, the opening and closing members 27a and 27b pivotally supported substantially at the center and left and right of the mounting board 21 are opened for a predetermined time (for example, 30 seconds). However, if the number of winning balls received by the open / close members 27a, 27b during opening is ten, the open / close members 27a, 27b are closed even before a certain time has elapsed. In addition,
The opening / closing members 27a and 27b are connected to a solenoid 28 (not shown; however, shown in the block diagram of FIG. 4) via a link member (not shown) so that the opening / closing members 27a and 27b are opened when the solenoid 28 is excited. It has become.

The hit ball received by the opening / closing members 27a and 27b rolls rearward in the winning space 29 formed substantially at the center of the mounting board 21. Behind the winning space 29,
Three fall openings for the winning ball to fall downward are formed, the center of which is a V winning opening 30 as a continuous winning opening, and the left and right are normal winning openings. V winning opening 30
A winning ball detection switch 31 (not shown; however, shown in the block diagram of FIG. 4) faces and detects a hit ball that has won the V winning opening 30. V winning ball detection switch 3
When 1 is turned on, the open / close members 27a and 27b are repeatedly opened for a certain period of time. That is, when the big hit game state is set, the opening and closing member 27
The winning prize ball accepted by the opening of the a and 27b wins the V winning opening 30 to establish the continuation right, and the variable prize winning device 20 corresponds to the number of times the continuation right is established
Is repeatedly performed, so that a large amount of winning balls are generated in a short time. However, the number of repetitions described above is set to a maximum of 16 times on condition that a hit ball is hit into the V winning opening 30.

In order to count the number of hit balls received by the opening / closing members 27a and 27b, a winning ball number detection switch 32 (not shown; however, a block diagram of FIG. Is displayed). The winning ball number detection switch 32 wins not only the winning ball guided to the winning space 29 and won in the V winning opening 30 but also the normal winning opening formed on the left and right sides of the V winning opening 30. It is arranged at a position where a winning ball can be detected. The winning ball that has passed through the winning ball number detection switch 32 flows down along the back surface of the game board 1 and is processed as a winning ball.

In addition to the above-described configuration, the variable winning device 20 has a starting memory lamp for notifying that the hit balls having been won in the starting winning ports 4a to 4c have been stored at the time of the jackpot game state or the variable display of the symbol display device 25. 33 (symbol display device 25
Located below).

The game operation of the pachinko machine 1 is controlled by a control circuit formed on a control circuit board housed in a control circuit board box (not shown). The control circuit is shown in FIG. . FIG. 4 is a block diagram of the control circuit. The control circuit uses a microcomputer 50 as a control center. The microcomputer 50 has an external ROM 5 as storage means.
1. An external RAM 52 as a storage means is connected.

On the other hand, start winning ball detection switches 15a-15c for detecting winning balls in the start winning ports 4a-4c,
A V-prize ball detection switch 31 for detecting a prize ball in the V-prize port 30 and a prize-ball number detection switch 32 for detecting a prize ball received by the opening / closing members 27a and 27b are transmitted to the microcomputer 50 via a waveform shaping circuit 53. It is connected. The clock generation circuit 55 outputs an external interrupt signal to the INT terminal of the microcomputer 50 via the frequency divider 54. When power is supplied to the power supply circuit 57, the reset signal generation circuit 56 outputs a reset signal. The reset signal is supplied to the microcomputer 5
0 is input to the RST1 terminal, and an initial program (not shown) is started.

A display drive circuit 58, a display selection circuit 59, and a driver 60 are connected to each output port of the microcomputer 50. The symbol display device 25 and the starting memory lamp 33 are connected to the display drive circuit 58 and the display selection circuit 59. These displays are dynamically driven by outputting selected data and display data from the microcomputer 50 at regular intervals. That is, each display unit is selected by the display selection circuit 59 and displayed according to the output signal of the display drive circuit 58 at that time. The driver 60 operates in response to a signal from the microcomputer 50 to drive the open / close solenoid 28, the big hit lamps 11a and 11b, the operation lamps 13a and
Lighting operations of 13b, 14a, 14b, etc. are controlled respectively.

Next, of the game operations controlled by the above-described control circuit, an example of the probability improving process will be described with reference to the flowcharts of FIGS. First, as shown in FIG. 2, it is determined whether or not the start winning ball detection switch 33 has been turned on in step 110. If not, the start winning subroutine ends.
If so, it is determined in step 120 whether or not the value of the starting storage counter C1 constituting the storage means is smaller than 4. If smaller, the value of the starting storage counter C1 is updated by one in step 130. The start storage counter C1 is for allowing the symbol display device 25 to fluctuate, and when the value is 1 or more, the symbol display device 25 starts to fluctuate by a fluctuation routine (not shown). Also,
When the fluctuation starts, the value of the start storage counter C1 is decremented by one. After the processing of steps 120 and 130 described above,
At step 140, the value of the starting integration counter C2 constituting the storage means is updated one by one. Start integration counter C2
Is for counting the number of winning balls hitting the starting winning ports 4a to 4c from the time of power-on.

Next, the probability improving subroutine shown in FIG. 1 will be described. At step 10, it is determined whether or not a big hit has occurred, and if not, the probability improving subroutine ends. If it is a big hit, it is determined in step 20 whether or not the value of the starting integration counter C2 is smaller than 51. When the value of the start integration counter C2 is greater than 51, it is considered that a predetermined period has elapsed since the power was turned on at the time of opening the store, and the jackpot determined in step 10 in step 30 is "3" or "7" or "9". It is determined whether or not any one of the two eyes is the one. If not, the probability improvement subroutine ends. On the other hand, when it is determined in step 20 that the value of the starting integration counter C2 is smaller than 51, or in step 30, it is determined that the big hit is any one of "3", "7", or "9". At times, a high probability flag is set in step 40. As a result, the cycle in which the big hit symbol appears in the subsequent fluctuations is shortened. Such a game that has a possibility of shifting to a high probability when the value of the start integration counter C2 is smaller than 51 is one of special game states. In addition,
The change of the probability is set based on the flag described above in a probability change subroutine (not shown).

As described above, in this embodiment, any combination of big hit symbols can be selected from when the power is turned on at the time of opening the store until the winning number of hit balls in the starting winning openings 4a to 4c reaches 50. Regardless of the big hit, the probability is improved, so that the atmosphere of the game hall at the time of opening the store can be excited. In addition, the starting winning opening 4a from the time of power-on.
When the number of winning balls hitting 4c exceeds 50, the time has elapsed since the store opened, and the condition for changing to the high probability is set to the normal state. The transition from the high probability to the low probability may be shifted to the low probability based on the occurrence of the first big hit, or based on the occurrence of the second big hit or the occurrence of the big hit more times. You may make it shift to a low probability.

In the above-described embodiment, the condition for improving the probability at the time of turning on the power has been described as being all combinations of the big hit symbols. However, other conditions, for example, the combination of the symbols displayed at the time of stoppage are specified. It is good also as a condition whether it is constituted only from a design. FIG. 3 shows an example of an operation under such conditions. Hereinafter, the flowchart of FIG. 3 will be described.

First, at step 210, it is determined whether or not the combination of the displayed symbols is composed only of "3" and "7". When it is determined that such a combination is composed, the symbol is determined at step 220. It is determined whether or not the value of a change number counter C3 as a storage unit that counts the number of changes since the power of the display device 25 is turned on is smaller than 51. When it is determined that the variation counter C3 is greater than 51, it is considered that a predetermined period has elapsed since the power was turned on at the time of opening the store, and the probability improvement subroutine ends.
When it is determined that it is smaller than 1, the next step 25
Go to 0. On the other hand, when it is determined in step 210 that the displayed symbol is not composed only of “3” and “7”, it is determined in step 230 whether or not a big hit has occurred. If the big hit is completed, it is determined whether or not the big hit is any one of "3", "7" and "9". If not, the probability improvement subroutine ends. If it is determined in step 220 that the value of the variation counter C3 is smaller than 51,
Alternatively, when it is determined in step 240 that the big hit is any one of “3”, “7”, and “9”, a high probability flag is set in step 250. As a result, the cycle in which the big hit symbol appears in the subsequent fluctuations is shortened. The change of the probability is set based on the flag described above in a probability change subroutine (not shown).

Also in the above-described embodiment, when the display symbol is composed of only a specific symbol combination between the time when the power is turned on at the time of opening the store and the time when the symbol display device 25 changes 50 times, Since the probability is improved, the atmosphere of the game hall at the time of opening the store can be enhanced. In addition, the number of times the symbol display device 25 has changed 50 times since the power was turned on.
When the number of times has exceeded the number of times, since the time has elapsed since the opening of the store, the condition for changing to the high probability is set to the normal state. In this embodiment, the shift from the high probability to the low probability may be shifted to the low probability based on the occurrence of the first big hit, or the occurrence of the second big hit or more times may be performed. The transition to the low probability may be made based on the occurrence of a big hit.

Although the configuration and operation of the pachinko machine 1 according to the embodiment have been described above, according to the embodiment, a pattern which appears relatively well within the predetermined period after the power is turned on at the time of opening the store, compared to the prior art, is provided. When the combination appears, the probability is changed to the high probability, so that the atmosphere of the game hall at the time of opening the store can be excited. In the above-described embodiment, the number of winnings in the starting winning opening and the number of times the symbol display device fluctuates are shown as the predetermined period from when the power is turned on, but, for example, the predetermined time (for example, 30 minutes) has elapsed. May be used as a condition. Further, the values of the start winning number, the number of fluctuations, the high probability, and the low probability in the above-described embodiment are examples,
It can be set arbitrarily. In addition, in order to distinguish between power-on at the time of opening a store and power-on at the time of recovery from a failure, a change to a high probability based on power-on is performed only when a predetermined switch operation or a permission signal from the management computer is derived. The processing may be executed. Furthermore, in the above-described embodiment, the opening and closing members 27a and 27b are opened based on the display result of the symbol display device 25. However, a predetermined game value is given to the symbol display device based on the display result. A pachinko machine having any game content may be used.

[0024]

As is apparent from the above description, in the present invention, a specific game state other than the normal game state can be maintained when the power is turned on. In the above, it is possible to reduce the possibility that the interest of the game is reduced. Thereby, it is possible to suppress the possibility that the player will be disadvantageous at least when the power is turned on. Also, in a gaming machine in which the special game state is caused by the variable display of the variable display device, the game machine can be placed in a special game state even when the power is turned on. It is possible to prevent the interest of the game from decreasing when the power is turned on again during operation or during business hours.
