Abstract

PROBLEM TO BE SOLVED: To provide a Pachinko (Japanese pinball game) machine capable of restricting speculative nature while preventing big losses on the side of a game parlor from occurring by ending a high probability period for big wins without arousing dissatisfaction on the part of a player when the high probability period is repeated by a specified number of times. SOLUTION: When a big win occurs (S42: Yes), a value of a pictorial design counter is referred to. If the value is from 0 to 4 (S43: Yes), it is a special big win. The number of consecutive special big wins is limited up to 4 to prevent speculative nature from escalating excessively. If the value of the consecutive high probability counter is more than 4 (S44: Yes), the high probability period cannot be continued beyond that. Therefore, operation of '+5' is performed to the value of the pictorial design counter to change the special big win to a normal big win having a larger number of opening-closing rounds of a big prize port (S54), and the process goes to the one for the normal big win (S6).

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball game machine typified by a pachinko game machine or the like that plays a game by hitting a ball into a game area, and more particularly, to a predetermined condition based on a display result of a variable display device. The present invention relates to a ball game machine in which a special game state is set and a predetermined game value is given to a player.

[0002]

2. Description of the Related Art A ball game machine of this type is provided with a variable display device capable of variably displaying a plurality of types of symbols.
This variable display device includes a mechanical rotary drum with a plurality of types of patterns drawn on the surface of a reel, a CRT (Cathode Ray
Tube) and an image display device such as an LCD (Liquid Crystal Display). The variable display of the display device is started when a ball hit into the game area passes through a predetermined gate. When the result of the variable display becomes a predetermined jackpot display, a special game state is established under a predetermined condition, and a predetermined game value is given to the player. Based on the predetermined game value, for example, a special winning opening (large winning opening) or the like provided in the game area so that a hit ball can easily win is opened a plurality of times under predetermined conditions.

[0003] In this ball-and-ball game machine, in order to further interest the player, if the result of the variable display is a specially determined special jackpot display among a plurality of types of jackpot displays, the subsequent jackpot display will be performed. There is one in which the probability is improved so that a jackpot display is generated at relatively short intervals. The period in which the probability is improved, that is, the high probability period is continued after the special jackpot display occurs, until the jackpot display occurs a predetermined number of times (for example, once or twice) except during the special game state. You. Therefore, if a special jackpot is displayed during the high probability period, the high probability period is extended, so that the player can be satisfied.

[0004]

However, since the high probability period is extended as long as the special jackpot display continues during the high probability period, there is a problem that the gambling property becomes too high. . In addition, if the high probability period is continued for a long time, the opening time of a special winning opening or the like becomes extremely long, so that there is a problem that the game hall is greatly damaged. On the other hand, forcibly terminating the high probability period at a predetermined number of times, although it is useful for suppressing gambling and preventing a great deal of damage to the game arcade, there is a problem that the player is dissatisfied. is there.

[0005] The present invention has been made to solve the above-described problem, and when the high probability period has been continued for a specified number of times, the high probability period is terminated without giving any complaint to the player. An object of the present invention is to provide a ball game machine capable of suppressing gambling and preventing a great deal of damage to a game arcade.

[0006]

Means for Solving the Problems In order to achieve this object, a ball game machine of the present invention includes a display device capable of variably displaying a plurality of types of identification information. As a result of the variable display by the display device, When a predetermined first display is displayed, a special game state is established under predetermined conditions, and a first game value is given to the player. On the other hand, when a predetermined second display is displayed. Becomes a special game state under predetermined conditions, a second game value different from the first game value is given to the player, and the first or the next special game state occurs thereafter at least until the next special game state occurs. The display probability of the second display is a high probability, and the display frequency of the second display during the period in which the display probability of the first or second display is the high probability is a specific number. Judgment means for judging whether or not the number has been reached And if the determination means determines that the number of times of display of the second display during the high probability period has reached a specific number of times, the first or second display is provided with a game value most advantageous to a player. And control means for changing the display to the one given with a symbol and executing a process of ending the high probability period.

According to the ball game machine of the present invention, when a plurality of types of identification information are variably displayed and the first display is displayed on the display device, a special game state is established under predetermined conditions. Is given a first game value. On the other hand, when the second display is displayed on the display device as a result of the variable display, the special game state is established under a predetermined condition, the second game value is given to the player, and at least the next special game state is thereafter provided. Until the event occurs, the probability that the first or second display (big hit display) is displayed is set to a high probability. During this high probability period the second
When it is determined by the determination means that the number of times of display has reached a specific number, the control means changes the jackpot display to a jackpot display in which a game value most advantageous to the player is provided. , A high probability period end process is executed. Therefore, the continuation of the high probability period can be limited to a specific number of times, and the high probability period can be ended by a jackpot display in which a game value most advantageous to the player is given.

[0008]

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. In this embodiment, a pachinko game machine will be described as an example of a ball game machine. FIG. 1 is a front view of a gaming board of a pachinko gaming machine according to a first embodiment. The pachinko gaming machine of the first embodiment is a so-called first-class pachinko gaming machine. Around the gaming board 1, there are provided a plurality of winning ports 2 from which 5 to 15 gaming balls are paid out when a hit ball wins. In the center of the game board 1, a liquid crystal (LCD) display 3 for displaying a plurality of kinds of symbols as identification information is provided. The display screen of the LCD display 3 is divided into three parts in the horizontal direction, and in each of the three divided display areas, a symbol is fluctuated and displayed.

Below the LCD display 3, a symbol operation gate (first type starting port) 4 is provided. When the hit ball passes through the symbol operation gate 4, the variable display on the LCD display 3 is started. Below the symbol operation gate 4, a special winning opening 5 is provided.
The special winning opening 5 is provided for a predetermined time (for example, 30) so that the hit ball can easily win when the display result after the change of the LCD display 3 matches one of the predetermined combination of symbols (big hit display). Until seconds elapse, or
It is a winning opening that is opened (until 10 hit balls are awarded).
In the special winning opening 5, a V zone 5a is provided. When a hit ball passes through the V zone 5a while the special winning opening 5 is open, a continuation right is established, and the special winning opening 5 is opened. After the closing, the special winning opening 5 is opened again for a predetermined time (or until a predetermined number of hit balls are won in the special winning opening 5). The state in which the opening and closing operation of the special winning opening 5 can be performed is a state in which a predetermined game value is given (special game state).

[0010] As a result of the variable display, the jackpot display displayed on the LCD display 3 has two types, a normal jackpot display as a first display and a special jackpot display as a second display.
There are types. In the normal jackpot display, the special game state is set as described above, and the special winning opening 5 is opened for a predetermined time.
In the normal jackpot display, the opening and closing operation of the special winning opening 5 can be repeated up to 16 times (16 rounds).

On the other hand, in the special jackpot display, the special game state is established, the special winning opening 5 is opened for a predetermined time, and after the special game state ends, the jackpot display is continued for two times. Except during the special gaming state, the probability of occurrence of the jackpot display is improved by 10 times. In the special jackpot display, the opening and closing operation of the special winning opening 5 can be repeated up to 14 times (14 rounds), which is two times (two rounds) less than the normal jackpot display. The period in which the probability of occurrence of the jackpot display is improved is not necessarily limited to the period from the end of the special game state until the jackpot display is continued twice, and a predetermined number other than two, for example, One or three times, or three or more times, until it is continued.

There are 15 combinations of symbols in the jackpot display in this embodiment. Of these, 10 combinations of symbols are usually jackpot displays, and 5 combinations of symbols are special jackpot displays.

FIG. 2 is a block diagram showing an electrical configuration of the pachinko gaming machine. The control unit C of the pachinko machine is
CPU 11, which is an arithmetic unit, ROM 12, which stores each control program executed by the CPU 11, and RAM 13, which is a memory for storing various data and the like
And These CPU 11, ROM 12, R
The AMs 13 are connected to each other via a bus line 14. The bus line 14 is also connected to an input / output port 15, which is connected to the display device D and another input / output device 16. That is, the control unit C
Sends an operation command to the display device D and other input / output devices 16 via the input / output port 15 to control these devices. The variable display on the LCD display 3 and the opening / closing operation of the special winning opening 5 are also performed based on the operation command issued from the CPU 11.

The RAM 13 of the control unit C has a hit counter 13a, a symbol counter 13b, a high probability flag 13c,
High probability remaining counter 13d, high probability continuation counter 13e,
Each memory such as four symbol rotation memories 13f to 13i is provided.

The hit counter 13a is a counter for determining whether or not the result of the variable display on the LCD display 3 is a big hit. The value of the hit counter 13a is updated in the range of "0 to 399" by the 2 ms interval interrupt processing of FIG. When the hit ball passes through the symbol operation gate 4, the big hit processing of FIG. 4 is executed. The value of the hit counter 13a is referred to in the big hit process. At the normal time when the jackpot occurrence probability is not set to the high probability, when the value of the hit counter 13a is "7", the jackpot is determined to be a jackpot. On the other hand, during a period in which the jackpot occurrence probability is high (hereinafter, referred to as a “high probability period”), the value of the hit counter 13a is “7”, “7”, and “0 to 399”. Is determined to be a big hit if it matches any one of the nine prime numbers determined at equal intervals within the range. That is, the number of winning numbers during the high probability period is increased from one to ten, so that the probability of a big hit is ten times the normal time during the high probability period.

The symbol counter 13b is a counter for determining a winning symbol displayed when a big hit occurs. As described above, in the present embodiment, there are ten combinations of symbols for ordinary jackpots and five combinations of symbols for special jackpots.
To 14 ”. If the value of the symbol counter 13b is "0 to 4", a special jackpot is displayed,
In the case of “5 to 14”, a jackpot is usually displayed. This symbol counter 13b is updated by the hit counter 13a.
Is performed by the 2 ms interval interrupt processing of FIG.

The high-probability flag 13c is a flag indicating whether or not the jackpot occurrence probability is high. That is,
The high probability flag 13c is turned on during the high probability period, and is normally turned off. Note that even during the high probability period, the high probability flag 13c is turned off during the execution of the special game process of FIG.

The high probability remaining counter 13d is a counter that stores the number of remaining jackpots in which the high probability is continued. When a special jackpot occurs, “2” is set in the high-probability remaining counter 13d, and thereafter, when a normal jackpot occurs, the countdown is performed by “1”. When the value of the high-probability remaining counter 13d becomes "0" by the countdown, the high-probability flag 13c is turned off, and the high-probability period ends. In the present embodiment, after the end of the special game state, the high probability period is continued except during the special game state until two big hits occur. Therefore, as described above, “2” is stored in the high probability remaining counter 13d. Is set. However, if the high probability period continues until one big hit occurs after the end of the special game state, "1" is set to the high probability remaining counter 13d.

The high-probability continuation counter 13e is a counter that stores the number of continuous high-probability continuations. When a special jackpot occurs, the value is counted up by “1”. If the value of the high-probability continuation counter 13e reaches "4" as a result of the count-up, it means that the high-probability period has already been continued (updated) four times.
Continuation of a higher probability period is prohibited. More specifically, if the special probability jackpot is further increased while the value of the high-probability continuation counter 13e has reached “4”, the number of openable rounds of the special winning opening 5 is larger for the ordinary jackpot than for the special jackpot. Since there are two more rounds than in the case of, the special jackpot is changed to a normal jackpot. Since the normal jackpot does not continue the high probability period, the change of the jackpot symbol can limit the continuation of the high probability period to a predetermined number of times (four times in this embodiment). The value of the high probability continuation counter 13e is cleared to "0" at the end of the high probability period.

The symbol rotation memories 13f to 13i are LCD
This is a memory for storing the rotation (fluctuation) pattern of the symbol displayed on the display 3, the result of the fluctuation display, the presence or absence of a big hit, and the like. When the hit ball passes through the symbol operation gate 4, the big hit process of FIG. 4 is executed, and as a result, each information (symbol rotation pattern, fluctuation display result, presence / absence of big hit, etc.) is stored in the symbol rotation memories 13f to 13i. Is stored. Variable display on the LCD display 3
Is opened and closed based on the data stored in the symbol rotation memories 13f to 13i. It should be noted that four symbol rotation memories 13f to 13i are provided so that up to four passing of the hit ball through the symbol operation gate 4 can be stored.

The display device D includes a CPU 21, a program ROM 22, a work RAM 23, and a video RAM 24.
, Character ROM 25, image controller 26
, An input / output port 27 and the LCD display 3. The CPU 21 of the display device D responds to the operation command output from the control unit C to the LCD display 3.
The program ROM 22 stores a program executed by the CPU 21. The work RAM 23 is a CPU
21 is a memory that stores work data used when the program is executed by the program 21.

The video RAM 24 is a memory in which data to be displayed on the LCD display 3 is stored.
The display content of the D display 3 is changed. That is, the change display of the symbol in each display area is performed by rewriting the contents of the video RAM 24. The character ROM 25 is a memory for storing character data such as symbols displayed on the LCD display 3. The image controller 26 includes a CPU 21, a video RAM 24,
The timing of each of the input / output ports 27 is adjusted to interpose the reading and writing of data, and the display data stored in the video RAM 24 is displayed on the LCD display 3 at a predetermined timing with reference to the character ROM 25.

Next, the jackpot processing in the pachinko game machine configured as described above will be described with reference to the flowcharts of FIGS. FIG. 3 is a flowchart of an interval interruption process that is periodically executed every 2 ms. In this processing, first, the symbol rotation memories 13f to 13f
Based on the data stored in one of the 3i, a symbol rotation process (variable display process) of the LCD display 3 and a jackpot process such as opening of the special winning opening 5 are performed (S1). As described above, each of these processes is performed by the control unit C from each device 1.
The operation commands are output to the devices 6 and 6D, and are executed in the devices 16 and D.

Thereafter, the update processing of the hit counter 13a is performed (S2). In the update process of the hit counter 13a, first, the value of the hit counter 13a is incremented by "+1" (S21). As described above, the value of the hit counter 13a is updated in the range of "0 to 399". Therefore,
It is determined whether or not the value of the hit counter 13a which is “+1” is 400 or more (S22). If the value is 400 or more (S22: Yes), the value of the hit counter 13a is cleared to 0 (S23), If there is (S22: No)
The update process (S2) of the hit counter 13a is ended as it is.

After the update processing of the hit counter 13a (S
2), the symbol counter 13b is updated (S)
3). First, the value of the symbol counter 13b is incremented by "+1" (S31). Since there are fifteen types of jackpot symbols, the value of the symbol counter 13b is updated in the range of “0 to 14”. Therefore, if the value of the symbol counter 13b to which "+1" has been added is 15 or more (S32: Yes), the symbol counter 1
The value of 3b is cleared to 0 (S33), and if it is less than 15 (S32: No), the symbol counter 13b updating process (S3) ends as it is.

FIG. 4 is a flowchart of the jackpot process. This processing is executed when the hit ball passes through the symbol operation gate 4. In the jackpot processing, the above 2m
Since the hit counter 13a and the symbol counter 13b updated in the interval interrupt process of s are referred to and each data is stored in the symbol rotation memories 13f to 13i, the interrupt process is not executed during the execution of the big hit process. As described above, first, execution of the interrupt processing is prohibited (S
41).

After the execution of the interruption process is prohibited (S41), it is determined whether or not a big hit has occurred based on the value of the hit counter 13a (S42). If the high probability flag 13c is off (normal time), the value of the hit counter 13a is "7". On the other hand, if the high probability flag 13c is on (high probability), the hit counter 13a is turned on. Is "7",
If it matches any of the nine prime numbers evenly determined within the range of “0 to 399” in addition to “7”, a big hit is won. As a result of checking the value of the hit counter 13a, if it is not a big hit (S42: No), the process proceeds to S46.

On the other hand, as a result of checking the value of the hit counter 13a, if it is a big hit (S42: Yes), the value of the symbol counter 13b is referred to check the type of the big hit (S43). As a result of the reference, the symbol counter 13
If the value of b is from 0 to 4 (S43: Yes), it is a special jackpot. The special jackpot is limited to a maximum of four times so as not to increase gambling. Therefore, when a special jackpot occurs (S43:
Yes), it is checked whether the value of the high-probability continuation counter 13e storing the number of continuations is 4 or more (S4).
4). If the value of the high-probability continuation counter 13e is not 4 or more (S44: No), since the high-probability period can be continued, the special jackpot is permitted and the special jackpot process is executed (S5).

In the special jackpot processing (S5), first, the value of the high probability continuation counter 13e is incremented by "1" (S5).
51). In the case of a special jackpot, the high probability period is continued until two jackpots are generated thereafter. Therefore, 2 is set in the high probability remaining counter 13d to store the number of remaining jackpots. Is performed (S52). Further, the high probability flag 13c is turned on to indicate that the high probability period is in progress (S53). After the high probability flag 13c is turned on, the process proceeds to S46.

On the other hand, if the value of the symbol counter 13b is 5 to 14 in the process of S43 (S43: No),
Usually a jackpot. In this case, an ordinary big hit process is executed (S6). The process at the time of the ordinary big hit (S6) is a process of ending the high probability period according to the situation. In the process of the normal jackpot (S6), first,
The value of the high-probability remaining counter 13d is checked (S61), and if the value is 0 (S61: Yes), the high-probability period has already been ended, so this normal jackpot processing (S61)
Step 6) is skipped, and the process proceeds to S46. If the value of the high probability remaining counter 13d is not 0 (S61: N
o), the value of the high-probability remaining counter 13d is decremented by "-1" in order to subtract the remaining number of large hits during the high-probability period by one (S62). Then, again, the high-probability remaining counter 13
It is checked whether the value of d is 0 (S63), and if the value is 0 (S63: Yes), the high probability continuation counter 13e
Is cleared to 0 (S64), the high probability flag 13c is turned off (S65), and the high probability period ends. As a result of checking the value of the high-probability remaining counter 13d again (S63), if the value is not 0 (S63: N
o) The process proceeds to S46 while the high probability period continues.

In the process of S43, the value of the symbol counter 13b is "0 to 4" (S43: Y
es) Even if a special jackpot is confirmed, if the value of the high probability continuation counter 13e is 4 or more (S44: Ye)
s) The high probability period cannot be continued any longer.
Therefore, in such a case, a jackpot with a large number of openable / closable (number of rounds) of the special winning opening 5 is generated to end the high probability period while giving the player a sense of satisfaction. The number of openable / closable (number of rounds) of the special winning opening 5 is 14 rounds in the special jackpot display and 16 rounds in the normal jackpot display. Therefore, the value of the symbol counter 13b is calculated by "+5", and the special jackpot display is changed to the normal jackpot display (S45). For the special jackpot, the value of the symbol counter 13b is any one of “0 to 4”, and by calculating “+5” to this value, the symbol counter 13b is calculated.
The value of b becomes one of “5 to 9”, and the special jackpot is changed to a normal jackpot with a larger number of rounds.
After the value of the symbol counter 13b is changed to the ordinary jackpot (S45), the process shifts to the above-described process of the ordinary jackpot in S6. The process of S45 is a process that can be executed until the value of the high probability continuation counter 13e is cleared to 0 by the process of S64, that is, until the high probability period ends.

In the case where the number of openable and closable times (number of rounds) of the special winning opening 5 is not determined for each special jackpot display or ordinary jackpot display, the number of rounds is determined for each symbol of the jackpot display. In the processing of S45,
The special jackpot display may be changed to the symbol of the jackpot display having the largest number of rounds. However, in this case, it is necessary to end the high-probability period. Therefore, even if the symbol after the change is a special jackpot, the process proceeds to S6 after the symbol is changed. Further, the special jackpot display may be changed to a normal jackpot display having the largest number of rounds.

In the process of S46, the hit counter 13a
Based on the value of the symbol counter 13b and the like, four patterns of data (information) such as the rotation pattern of the symbol variably displayed on the LCD display 3 and the result of the variable display and the presence or absence of the opening of the special winning opening 5 are provided. Certain rotating symbol memories 13f to 13
i. Rotating symbol memories 13f to 13i
Are referred to and used in the above-described processing of S1 (FIG. 3). After each data is stored in one of the rotating symbol memories 13f to 13i (S4
6) The interrupt prohibited in the process of S41 is permitted (S
47), the jackpot process ends.

FIG. 5 shows a special winning state 5 in the special game state.
Is a flowchart showing the opening and closing process, that is, the special game process. This special game processing is the processing of S46 in the big hit processing of FIG. 4, and the symbol rotation memories 13f to 13i
Is performed based on the data stored in one of the.

During the special game state, the probability of occurrence of the jackpot is returned to the low probability even during the high probability period. Therefore, first, the state of the high probability flag 13c is saved to a predetermined area on the RAM 13 (S71),
3c is turned off (S72). Next, the special winning opening 5 is opened (S73), and after a predetermined number of hit balls are won (S74:
Yes), the special winning opening 5 is closed (S75). During the opening of the special winning opening 5 (S73), the special winning opening 5 is also closed when a predetermined number of hit balls do not win the special winning opening 5 within a predetermined time.

The ball hits the V zone 5a while the special winning opening 5 is open.
(S76: Yes), and the special winning opening 5
If the opening / closing operation is still less than the predetermined number of times (S77: N
o), the special game can be continued. That is, if the opening and closing operation of the special winning opening 5 is less than 16 times in the case of a normal big hit and less than 14 times in the case of a special big hit (S7
7: No), the special game can be continued. Therefore, in such a case, the process proceeds to S73, and the special winning opening 5 is opened again (S73).

On the other hand, during the opening of the special winning opening 5, the hit ball does not pass through the V zone 5a (S76: No), or even though the hit ball passes through the V zone 5a, a large hit has already occurred. If the opening and closing operation of the winning opening 5 has been repeated a predetermined number of times or more (S77: Yes), the RA in the processing of S71.
The flag evacuated to the predetermined area on M13 is returned to the high probability flag 13c (S78), and the special game process is terminated. As described above, even during the high probability period, during the special game state, the jackpot occurrence probability is set to a low probability.

As described above, during the period when the probability of occurrence of the jackpot display is high (during the high probability period),
If the special jackpot is continued four times in total (S4
4: Yes), the value of the symbol counter 13b is calculated by "+5" (S45), and the special jackpot is set to the special winning opening 5
Is changed to a normal jackpot with a large number of openable / closable times (number of rounds), and after the change, the process of S6 for ending the high probability period is executed. Therefore, the number of continuations of the high probability period can be stopped at a maximum of four times, and the high probability period can be prevented from being extended forever. Therefore, there is no possibility that the gambling property is excessively increased or the game arcade is damaged significantly. Also, by ending the high probability period with a jackpot display with many rounds,
The high probability period can be ended while satisfying the player. Furthermore, for the special jackpot that occurred at the fifth time,
Since each special jackpot is changed to the corresponding normal jackpot, all the special jackpots are not changed to one specific normal jackpot. Therefore, the jackpot symbol after the high probability period has continued four times is not made into a biased symbol, and in this respect, the player does not feel uncomfortable.

Next, a second embodiment will be described with reference to the flowcharts of FIGS. The second embodiment is different from the first embodiment in that the scheme of changing the special jackpot symbol which has been generated for the fifth time continuously to the ordinary jackpot symbol having a large number of rounds is changed. Note that the pachinko gaming machine of the second embodiment is also a first-type pachinko gaming machine similar to the first embodiment, and the special game processing uses the processing of FIG. 5 as in the first embodiment. Hereinafter, the same portions as those of the first embodiment are denoted by the same reference numerals, and the description thereof will be omitted. Only different portions will be described.

In the second embodiment, a second symbol counter 13j is newly provided on the RAM 13. The second symbol counter 13j is a counter which is referred to when a special jackpot continues four or more times when a jackpot occurs, and is used to determine a jackpot symbol. In the pachinko gaming machine of this embodiment, the number of openable and closable times (number of rounds) of the special winning opening 5 is determined for each of the special jackpot display and the normal jackpot display, and the number of rounds is larger than that of the special jackpot display. The second symbol counter 13
j is updated within the range of the normal jackpot symbol "5 to 14". This second symbol counter 13j is updated as shown in FIG.
2 ms interval interrupt processing. In addition,
When the number of opening and closing rounds of the special winning opening 5 differs for each symbol of the jackpot, the second symbol counter 13j is updated within the range of the value of the symbol with a large number of rounds regardless of the special jackpot and the ordinary jackpot. .

FIG. 6 is a flowchart of an interval interruption process which is periodically executed every 2 ms in the second embodiment. In this process, an update process (S30) of the second symbol counter 13j is added to the interval interrupt process (FIG. 3) of the first embodiment. The update process (S30) of the second symbol counter 13j is a symbol rotation and big hit process (S1), and the update process of the hit counter 13a (S30).
2) and after the symbol counter 13b is updated (S3).

The updating process of the second symbol counter 13j (S3
0), first, the value of the second symbol counter 13j is "+
1 "(S301). The value of the symbol of the ordinary jackpot having a large number of openable and closable rounds of the special winning opening 5 is “5 to 14”. Therefore, the second symbol counter 13j which is "+1"
Is greater than or equal to 15 (S302: Yes), the value of the second symbol counter 13j is returned to 5 (S303), and if less than 15 (S302: No), the second symbol counter 13j is updated as it is (S302: No). S30) ends.

FIG. 7 is a flowchart of the jackpot process in the second embodiment. In this process, the part of the process of S8 is changed from the jackpot process of the first embodiment (FIG. 4). The big hit processing in FIG. 7 is also executed by the hit ball passing through the symbol operation gate 4.

As a result of referring to the value of the hit counter 13a in the process of S42, if it is a big hit (S42: Ye
s), the value of the high probability continuation counter 13e is checked (S8).
1) It is determined whether or not the high probability period can be continued, that is, whether or not a special jackpot can be generated.

If the value of the high-probability continuation counter 13e is 4 or more (S81: Yes), the high-probability period has already been continued four times, so that it cannot be continued any more.
Therefore, the value of the second symbol counter 13j is changed to the symbol counter 1
3b (S82) to prohibit the occurrence of the special jackpot. That is, the value of the second symbol counter 13j is “5 to 1”.
Since it is updated only in the range of the symbol of the normal jackpot of "4" (S30), the occurrence of the special jackpot is prohibited by writing the value of the second symbol counter 13j to the symbol counter 13b. On the other hand, high probability continuation counter 1
If the value of 3e is not 4 or more (S81: No), it is within the range where the high probability period can be continued, and the special jackpot can be tolerated. Therefore, in this case, the value of the symbol counter 13b is not rewritten.

In the process of S83, the symbol counter 13
The value of b is referred to. As a result, if the value of the symbol counter 13b is "0 to 4" (S83: Yes), the process goes to the special jackpot process (S5) because it is a special jackpot. On the other hand, as a result of referring to the value of the symbol counter 13b, if the value is "5 to 14" (S83: No), it is a normal big hit, so the processing shifts to a normal big hit processing (S6).

As described above, in the second embodiment, the number of special jackpots to be continued is limited to four at the maximum, so that the fifth jackpot symbol is changed to the ordinary jackpot symbol regardless of the symbol counter 13b. Is updated using the second symbol counter 13j. For this reason, the jackpot symbol after the high probability period has been continued four times does not become a biased symbol, and the player does not feel uncomfortable. In addition, the number of opening and closing rounds of the special winning opening 5 is larger in ordinary jackpots than in special jackpots, so that the high probability period can be ended by a jackpot having a larger number of rounds.

Next, referring to the flowchart of FIG.
A third embodiment will be described. This third embodiment is also a second embodiment.
Similar to the first embodiment, the method of changing the symbol of the special jackpot generated continuously for the fifth time to the symbol of the ordinary large jackpot having a large number of rounds is different from that of the first embodiment. The pachinko gaming machine of the third embodiment is also a first-type pachinko gaming machine similar to the first embodiment. Hereinafter, the same portions as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.
Only different parts will be described.

In the third embodiment, only the jackpot process (FIG. 4) of the first embodiment is changed. The 2 ms interval interrupt process (FIG. 3) of the first embodiment and the special game process (FIG. 3) FIG. 5) is also used in the third embodiment. Further, in the symbol counter 13b of the third embodiment, "1, 3, 5, 5"
Five special patterns of “7, 9” are special jackpots, and “0,
2,4,6,8,10-14 "are usually big hit symbols.

FIG. 8 is a flowchart of the jackpot process in the third embodiment. In this process, the part of the process of S9 is changed compared to the jackpot process of the first embodiment (FIG. 4). The big hit processing of FIG. 8 is also executed when the hit ball passes through the symbol operation gate 4.

As a result of referring to the value of the hit counter 13a in the process of S42, if it is a big hit (S42: Ye
s), the value of the symbol counter 13b is checked (S9)
1). When the value of the symbol counter 13b is "0, 2, 4, 6,
8, 10-14 "(S91: N
o) Since it is a normal jackpot, the processing shifts to the processing of the normal jackpot in S6. On the other hand, if the value of the symbol counter 13b is any of "1, 3, 5, 7, 9" (S91:
Yes), a special jackpot. In this case, it is checked whether the value of the high-probability continuation counter 13e is 4 or more in order to suppress the number of continuations of the special jackpot to four so as not to increase the gambling property too much (S92). If the value of the high-probability continuation counter 13e is not 4 or more (S92: No),
Since the high probability period can be continued, the special jackpot is permitted, and the process proceeds to the special jackpot (S5).

Even if a special jackpot is confirmed in the processing of S91 (S91: Yes), if the value of the high probability continuation counter 13e is 4 or more (S92: Yes), it is not possible to continue the high probability period any longer. Can not. Therefore,
In such a case, an AND logic of the value of the symbol counter 13b and the hexadecimal FEH is obtained, and the result is written to the symbol counter 13b (S93). Thereby, each value of “1, 3, 5, 7, 9” of the symbol counter 13b is set to “0,
2, 4, 6, 8 ", and the special jackpot is converted into a normal jackpot. In the conversion process from the special jackpot to the ordinary jackpot, after performing AND logic with the FEH, the result is simply loaded into the symbol counter 13b. Therefore, the program capacity for this conversion process is extremely small, Since there is no need to newly provide the second symbol counter 13j as in the second embodiment, the R
The capacity of the AM 13 can also be reduced.

After the value of the symbol counter 13b is converted from the special jackpot to the ordinary jackpot (S93), in the third embodiment, the high probability period is forcibly terminated regardless of the value of the high probability remaining counter 13d. ing. That is, the forced termination processing (S94 to S96) is performed by the high probability continuation counter 13
e and the value of the high-probability remaining counter 13d are both cleared to 0 (S94, S95), and the high-probability flag 13c is turned off (S96). Thus, the high-probability remaining counter 13d
Irrespective of the value of, the high probability period is forced to end.
As described above, the forced termination of the high probability period is performed by displaying the normal jackpot with a large number of rounds, so that the player is not dissatisfied. Note that this forced termination processing (S
94 to S96) can be used in the first and second embodiments.

Next, a fourth embodiment will be described with reference to FIGS. Hereinafter, the same portions as those of the first embodiment are denoted by the same reference numerals, and the description thereof will be omitted. Only different portions will be described. FIG. 9 is a front view of the game board of the pachinko gaming machine according to the fourth embodiment. The pachinko gaming machine of the fourth embodiment is different from the pachinko gaming machines of the first to third embodiments,
It is a so-called third class pachinko machine (so-called right).

Below the LCD display 3, a symbol operation gate 6 is provided. When the hit ball passes through the symbol operation gate 6, the variable display of the LCD display 3 is started. An electric accessory 7 is provided below the symbol operation gate 6. This electric accessory 7 is an LCD
It operates when the display result after the change of the display 3 matches one of the predetermined symbol combinations (big hit display) and is opened for a predetermined time. When the hit ball passes through a V zone (special winning opening) 7a provided in the electric accessory 7 during the operation of the electric accessory 7, a right generation state (special game state) is established. During this right generation state, when a hit ball passes through a third type starting port 8 provided at the upper right of the game board 1, a ball receiving member of the special winning opening 9 provided below the third type starting port 8 is provided. 9a, 9a is a predetermined time (for example, until 10 seconds elapse, or 10 shots) so that the shot is easy to win.
It will be open until you win a prize.

As a result of the variable display, the jackpot display displayed on the LCD display 3 includes a normal jackpot display as a first display and a special jackpot display as a second display.
There are types. In the normal jackpot display, the opening / closing operation of the special winning opening 9 can be repeated up to eight times (eight rounds) in the special game state described above. On the other hand, in the special jackpot display, the special winning state 9
Opening and closing operations can be repeated up to 16 times (16 rounds), and after the special game state ends, the jackpot display is generated until the jackpot display is continued twice, except during the special game state. Probability is improved by a factor of 10. As described above, the number of openable / closable (number of rounds) of the special winning opening 9 is:
The special jackpot display is eight times (8
Round) is increasing. The period in which the probability of occurrence of the jackpot display is improved is not necessarily limited to the period from the end of the special game state until the jackpot display is continued twice, and a predetermined number other than two, for example, , 1
This may be performed three or three times, or three or more times, until the continuation is continued.

In the fourth embodiment, the jackpot display is 15
There are combinations of street patterns. Of these, 10 combinations of symbols are usually jackpot displays, and 5 combinations of symbols are special jackpot displays.

FIG. 10 is a flowchart of an interval interruption process which is periodically executed every 2 ms in the fourth embodiment. In this process, an update process (S40) of the third symbol counter 13k is added to the interval interrupt process of the first embodiment (FIG. 3). The update process (S40) of the third symbol counter 13k includes a symbol rotation and big hit process (S1), and an update process of the hit counter 13a (S40).
2) and after the symbol counter 13b is updated (S3).

The third symbol counter 13k is provided in the RAM 1
3 is a counter that is referred to when a special jackpot is continued four times or more when a special jackpot occurs, and is used to determine a jackpot symbol. In the pachinko gaming machine of the fourth embodiment, the number of openable and closable (number of rounds) of the special winning opening 9 is 16 rounds in the special jackpot display and 8 rounds in the ordinary jackpot display, and the extra jackpot display is larger than the ordinary jackpot display. So the third symbol counter 13k
Is updated within the special jackpot design of “0 to 4”. In addition, when the number of opening and closing rounds of the special winning opening 9 differs for each symbol of the big hit, the third symbol counter 13 k
Regardless of the special jackpot and the ordinary jackpot, the value is updated within the range of the value of the jackpot symbol having a large number of rounds.

The update processing of the third symbol counter 13k (S4
0), first, the value of the third symbol counter 13k is “+”.
1 "(S401). Since the value of the symbol of the special jackpot with a large number of opening and closing rounds of the big winning opening 9 is "0 to 4",
If the value of the third symbol counter 13k that has been "+1" is 5 or more (S402: Yes), the third symbol counter 13k
Is cleared to 0 (S403), and if less than 5, (S4
02: No) The update process (S40) of the third symbol counter 13k is finished as it is.

FIG. 11 is a flowchart of the jackpot process in the fourth embodiment. This processing is different from the jackpot processing of the first embodiment (FIG. 4) from S101 to S10.
3 has been changed. The jackpot process in FIG.
This is executed when the hit ball passes through the symbol operation gate 6.

As a result of referring to the value of the hit counter 13a in the process of S42, if it is a big hit (S42: Ye
s), the value of the high probability continuation counter 13e is checked (S)
101). If the value of the high-probability continuation counter 13e is less than 4 (S101: No), it is within the range where the high-probability period can be continued. Therefore, in this case, referring to the value of the symbol counter 13b, if the value is "0 to 4" (S10
3: Yes), the special jackpot processing is executed (S
5) If "5 to 14" (S103: No), the process at the time of the ordinary big hit is executed (S6).

On the other hand, if the value of the high probability continuation counter 13e is 4
If this is the case (S101: Yes), the high probability period has already been continued four times, so it cannot be continued any further. Therefore, the high-probability period must be ended. However, in order to end the high-probability period without giving any complaint to the player, in the present embodiment, a special jackpot with a large number of opening and closing rounds of the special winning opening 9 is used. The high probability period is terminated. Therefore, the value of the third symbol counter 13k is written to the symbol counter 13b (S1).
02), the process proceeds to S6. In the processing of S6, the high-probability period ends according to the value of the high-probability remaining counter 13d (S64, S65). Note that S10
The branch from the process of 1 to the process of S102 is continued until the high probability period ends, that is, until the value of the high probability continuation counter 13e is cleared to 0 by the process of S64.

FIG. 12 is a flowchart showing the opening and closing process of the special winning opening 9 in the special game state, that is, the special game process. This special game processing is the processing of S46 in the big hit processing of FIG.
3i is performed based on the data stored in one of the 3i.

During the special game state, even if during the high probability period, the jackpot occurrence probability is returned to the low probability. Therefore, first, the state of the high probability flag 13c is saved in a predetermined area on the RAM 13 (S111), and the high probability flag 13c is turned off (S112). Next, when the hit ball passes through the third kind starting opening 8 (S113: Yes), the special winning opening 9 is opened (S114), and after a predetermined number of hitting balls (S115: Yes), the special winning opening is obtained. 9 is closed (S116). During the opening of the special winning opening 9 (S11
4) Even if a predetermined number of hit balls do not win the special winning opening 9 within a predetermined time, the special winning opening 9 is closed.

If the opening and closing operation of the special winning opening 9 is still less than the predetermined number of times (S117: No), the process proceeds to S113. When the hit ball passes through the third type starting port 8 (S1
13: Yes), the special winning opening 9 is opened again (S11).
4). That is, the opening and closing operation of the special winning opening 9 is repeated up to eight times in the case of a normal big hit and up to 16 times in the case of a special big hit.

On the other hand, if the opening and closing operation of the special winning opening 9 is repeated a predetermined number of times or more (S117: Yes), S11 is executed.
The flag saved in the predetermined area on the RAM 13 in the process 1 is returned to the high probability flag 13c (S118), and the special game process ends. As described above, even during the high probability period, during the special game state, the jackpot occurrence probability is set to a low probability.

As described above, in the pachinko gaming machine according to the fourth embodiment, the special jackpot has more open / close rounds of the special winning opening 9 than the ordinary jackpot, so that the number of open / close rounds 5 after the high probability period is continued four times. The jackpot for the first time is changed to a special jackpot, and end processing for a high probability period is performed. As a result, the number of continuations of the high probability period can be stopped at a maximum of four times, so that the gambling property is not excessively increased and the game hall is not greatly damaged. In particular, by terminating the high probability period with a jackpot display (special jackpot display) having a large number of opening and closing rounds of the special winning opening 9, it is possible to end the high probability period while satisfying the player.

Next, a fifth embodiment will be described with reference to the flowchart of FIG. In the fifth embodiment, the processing in the case where a big hit occurs after the special big hit is continued four times is different from the fourth embodiment. As the pachinko gaming machine of the fifth embodiment, a so-called third-type pachinko gaming machine (so-called right) is used as in the fourth embodiment. Hereinafter, the same portions as those of the fourth embodiment are denoted by the same reference numerals, and the description thereof will be omitted. Only different portions will be described. The big hit process (FIG. 13) in the fifth embodiment is also executed by the hit ball passing through the symbol operation gate 6. In addition, the processing of the fourth embodiment (FIGS. 11 and 12) is used for both the 2 ms interval interrupt processing and the special game processing.

As a result of referring to the value of the hit counter 13a in the process of S42, if it is a big hit (S42: Ye
s), the value of the high probability continuation counter 13e is checked (S)
121). If the value of the high-probability continuation counter 13e is less than 4 (S121: No), it is within the range in which the high-probability period can be continued. Therefore, in this case, referring to the value of the symbol counter 13b, if the value is “0 to 4” (S12)
2: Yes), the special jackpot processing is executed (S
5) If it is “5 to 14” (S122: No), the process at the time of the ordinary big hit is executed (S6).

On the other hand, when the value of the high probability continuation counter 13e is 4
If this is the case (S121: Yes), the high probability period has already been continued four times, so it cannot be continued any further. Therefore, the high-probability period must be ended. However, in order to end the high-probability period without giving any complaint to the player, in the present embodiment, a special jackpot with a large number of opening and closing rounds of the special winning opening 9 is used. The high probability period is terminated. Therefore, the value of the third symbol counter 13k is written to the symbol counter 13b (S1).
23) The jackpot is changed to a special jackpot.

The fifth embodiment differs from the fourth embodiment in the method of terminating the high probability period. That is, in the fourth embodiment, the high-probability remaining counter 1
According to the value of 3d, the high probability period is gradually ended (S
64, S65). However, in the fifth embodiment, the high-probability period is forcibly ended regardless of the value of the high-probability remaining counter 13d. Specifically, after writing the value of the third symbol counter 13k to the symbol counter 13b (S
123), the values of the high-probability continuation counter 13e and the high-probability remaining counter 13d are both cleared to 0 (S124, S12).
5) The high probability flag 13c is turned off (S12).
6). As a result, the high probability period is forcibly ended regardless of the value of the high probability remaining counter 13d. Even if the high probability period is forcibly ended in this way, the last big hit display is a special big hit display with a large number of rounds, so that the player is not dissatisfied. Note that the forcible termination processing (S124 to S126) can be used in the fourth embodiment.

The first to fifth embodiments have been described with reference to FIGS. 1 to 13. Among them, a pachinko game machine is used as the ball game machine according to claim 1, an LCD display 3 is used as the display device, a normal jackpot display is used as the first display, and a special jackpot display is used as the second display. . S44 and S8 are used as determination means.
1, S92, S101, and S121 correspond to the control means, and S45 and S6, S82 and S83, S93 to S96, and S102 and S6, S123 to S126 correspond to the control means.

The present invention has been described based on the embodiments. However, the present invention is not limited to the above-described embodiments, and various improvements and modifications can be made without departing from the gist of the present invention. Can easily be inferred.

For example, in the present embodiment, the electronic LCD display 3 is used for the symbol change display.
A display or a mechanical rotating drum using a reel with a design drawn on the surface may be used. Also,
The present invention is not limited to pachinko machines, but can be applied to all ball game machines capable of variable display.

In the processing of each step S52 in FIGS. 4, 7, 8, 11, and 13, the value of the high-probability remaining counter 13d is always reset to "2". However, instead of this, “2” may be added to the value of the high-probability remaining counter 13d.
Further, the conversion from the special jackpot to the ordinary jackpot in the first to third embodiments and the conversion from the ordinary jackpot to the special jackpot in the fourth or fifth embodiment may be performed using a conversion table.

In the present embodiment, the continuation of the high probability period is recognized up to the occurrence of four special jackpots. However, using a hard switch such as a dip switch or a switch on software,
You may comprise so that the continuation possible frequency of a high probability period can be set freely. Further, the continuation of the high probability period may be limited to a predetermined time. Further, the remaining number of times that the high probability period can be continued may be displayed to notify the player. In this case, if the specific number of times that the high-probability period can be continued is four, the high-probability continuation counter 13e changes from “4”.
May be subtracted and the result may be displayed.

If there is a special jackpot and a third jackpot to which a game value more advantageous than a normal jackpot is given, the jackpot after the high probability period has been continued a specified number of times is changed to the third jackpot. You may do it.

The number of open / close rounds of the special winning ports 5 and 9 in this embodiment is 14 rounds for special jackpots and 16 rounds for ordinary jackpots in the first class pachinko gaming machines (first to third embodiments). In the third-type pachinko gaming machine (the fourth and fifth embodiments), it has been described that the special jackpot is 16 rounds and the ordinary jackpot is 8 rounds. However, the present invention is not limited to this. For example, in a first-class pachinko gaming machine, a special jackpot is 12 rounds and a regular jackpot is 16 rounds, and in a third-class pachinko gaming machine, a special jackpot is 16 rounds and a regular jackpot is It may be one round. In addition, when the special jackpot is 16 rounds and the regular jackpot is 1 round, and the difference between the number of opening and closing rounds of the special winning openings 5 and 9 is large, the continuation of the high probability period is performed with the large number of rounds. , The player can be given greater satisfaction. In other words, the effect of the present invention is greater for a ball-and-play game machine having a large difference in the number of opening and closing rounds of the special winning openings 5 and 9 between the special jackpot and the ordinary jackpot.

[0080]

According to the ball game machine of the present invention, when the second display for continuing the high probability period is displayed a specific number of times during the high probability period, the high probability period is provided to the player. The game is ended with the jackpot display giving the most advantageous game value. Therefore, the continuation of the high probability period can be limited to a specific number of times, and gambling can be suppressed, and there is an effect that a great deal of damage to the game hall is not caused. In addition, the high probability period is ended by the jackpot display that gives the most advantageous game value to the player, that is, by the jackpot display with many payouts, so that the high probability period can be ended while satisfying the player. This has the effect.
