Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko game machine, and more particularly, to a symbol display device provided on a game board of a pachinko game machine, and more particularly to a lottery probability of a "hit" symbol display of a normal symbol display device. The present invention relates to a lottery probability control device for a symbol display device variably controlled in accordance with the following.

[0002]

2. Description of the Related Art In recent years, in this kind of pachinko gaming machine, a special benefit is generated for a player by a display screen of a symbol display device (a special symbol display device or a normal symbol display device) provided at the center of a game board. Things are already known.
For example, a plurality of symbols (numbers, patterns, etc.) of the special symbol display device fluctuate, and a game situation in which a symbol is called "win" or "big hit" is activated depending on a combination of symbols when the game is stopped. If a "big hit" occurs, a special winning combination, which is a special electric accessory provided below the game board surface, is continuously opened at predetermined intervals, and a large number of prizes are obtained during the interval, so that a large number of prizes are given to the player. A ball (hereinafter referred to as "prize ball") is paid out.

[0003] According to such a pachinko gaming machine, a player can obtain a large amount of prize balls once the state of "big hit" is obtained, and if the state of "big hit" continues several times, the player can win a big win. Therefore, the lottery probability at which a “hit” or “big hit” occurs has a high degree of interest, and it stimulates amusement.

Therefore, for example, this relates to the lottery probability of the special symbol display device. After the "big hit" state is completed, the lottery probability of the next occurrence of the "big hit" of the special symbol display device is shifted to a high probability. There is something like that.
The excitement is fueled by the fact that players can once again expect "big hits". Further, there is also a method in which the number of continuous opening of the special winning opening is set and controlled by a display symbol when a "big hit" occurs, thereby inspiring a player's gambling spirit and increasing a chance to obtain more prize balls.

[0005] Further, this partially relates to a normal symbol display device. As shown in Japanese Patent Application Laid-Open No. H10-15177, after the "big hit" state of the special symbol display device is completed, the next "big hit" is performed. After shifting the lottery probability of occurrence to high probability, and after the "big hit" with this high probability continues several times, the symbol fluctuation time of the ordinary symbol display device is shortened based on the limit of the number, and the subsequent lottery opportunities There is also a thing that raises. These are all intended to change the game content to enhance the interest of the player.

Further, as shown in Japanese Patent Application Laid-Open No. 9-285614, the symbol variation of the ordinary symbol display device depends on the number of winning balls stored in the first-type starting winning opening for starting the symbol variation of the special symbol display device. Shorten the time, or
There is also a method in which the random determination probability of the next occurrence of the "big hit" of the special symbol display device is changed. According to this, the player operates the game balls so that the number of the stored games increases, and
The game won't get tired of expecting the next big hit.

[0007]

However, all of these pachinko machines automatically shift to the high probability lottery probability after the end of the "big hit" state of the special symbol display device, or the normal symbol display device. In the end, the game content is determined by whether or not the special symbol display device is in a "big hit" state, and the player has a special feeling of expectation Do not mean.

[0008] Even if the symbol change time in the ordinary symbol display device is shortened, it is only necessary to display the "winning" symbol, but if it is not displayed, the special symbol display device may become "big hit" due to the symbol change. The abilities were low, and in the end, the players gradually awoke and lacked expectations, resulting in lack of sustainability of customer attraction.

Further, in Japanese Patent Application Laid-Open No. 9-285614, even if the symbol change time of the ordinary symbol display device is shortened, a prize ball to the first-type starting winning opening which starts the symbol change of the special symbol display device. If the "hit" symbol is not normally displayed on the symbol display device, the player's sense of expectation is lost, and the interest in the game is not so exciting.

An object of the present invention is to provide a pachinko gaming machine having a normal symbol display device on a game board, an electric winning device having a first-class start winning port, and a special symbol display device. A lottery probability control device of a symbol display device in a pachinko gaming machine in which a special symbol display device has a possibility of generating a "big hit" by setting a variable lottery probability that a "hit" occurs in a normal symbol display device. Is to provide. As a result, the player is not bored and the entertainment is more enjoyable.

[0011]

In order to solve this problem, according to the first aspect of the present invention, there is provided a lottery probability control device for a symbol display device in a pachinko game machine, comprising: And a first symbol display device in which a symbol change is activated by a prize of a game ball to a first-class start winning port of the electric symbol device, the first symbol display device has a "big hit". In a pachinko gaming machine in which a special benefit is given to a player by generating a symbol, a second symbol display device for setting a condition for switching a first-type starting winning prize port of the electric winning device to a winning ball receiving state is provided. A first-type start winning probability setting means for providing on the board and setting a high probability that a specific symbol for switching to the winning ball receiving state of the first-type start winning port is established on the second symbol display device; Seed start Winning ball in the mouth is to summarized in that and a symbol variation operation start control means for controlling so as to provide the start-up of all the first symbol display device without disabling.

According to the pachinko gaming machine having the above-described structure, the first symbol display device starts changing symbols when a game ball enters a first-type starting winning port of the electric winning device provided on the game board, and stops. A "big hit" occurs depending on the symbol, and a special advantage is given to the player that a large amount of prize balls are paid out. However, a second symbol display device provided on the game board surface has a first type start winning port of the electric winning device. Is switched to the winning ball receiving state, the probability that a specific symbol is established is set high by the first-type starting winning probability setting means, and the first-type starting winning port is set without invalidating all the game balls that have won. By controlling the symbol change operation start control means so as to be used for starting the one symbol display device, the number of symbol changes of the first symbol display device increases, and the possibility of occurrence of "big hit" increases. Luo player can enjoy the game without feeling the loss feeling.

At this time, the number of symbol fluctuations of the second symbol display device is counted by the counting means as in the second aspect of the invention, and when the counted number reaches a preset number, If the first-type start winning opening is switched to the winning ball receiving state, the probability that the first-type starting winning opening is switched to the receiving state of the winning ball increases as the number of symbol changes of the second symbol display device increases, As a result, the possibility of occurrence of a “big hit” symbol on the first symbol display device is increased.

The invention according to claim 3 is a more specific example of the invention according to claim 1, and a lottery probability control device for a symbol display device of this pachinko game machine is provided on a game board. A normal symbol display device in which a symbol change is activated in response to a predetermined rolling state of the game ball, and a first-type start winning opening that is switched to a winning ball receiving state by fixing a "hit" symbol of the normal symbol display device. An electric prize device, and a special symbol display device in which a symbol change is activated by a prize in a first-class starting prize port of the electric prize device, and a player is determined by determining a "big hit" symbol of the special symbol display device. In pachinko machines where special benefits are given to
A mode switching unit that includes a high-probability mode for setting the `` hit '' probability of the ordinary symbol display device to a high probability and a low-probability mode for setting the low probability, and switches between the high-probability mode and the low-probability mode, Mode switching control means for activating the mode switching means to shift from the low-probability mode to the high-probability mode when the number of symbol changes of the ordinary symbol display device reaches a predetermined number. is there.

According to the third aspect of the present invention, the high probability mode in which the probability that the normal symbol display device displays the "hit" is set to the high probability and the low probability mode in which the probability is set to the low probability are set in the mode. The switching from the low-probability mode to the high-probability mode is normally performed when the number of symbol changes of the symbol display device reaches a predetermined number, so that a "big hit" of the special symbol display device is generated. Is related not only to the luckiness of the symbol fluctuation but also to the degree of the symbol fluctuation of the ordinary symbol display device, so that it is possible to increase the amusement and to enjoy the game.

At this time, the number of symbol fluctuations of the ordinary symbol display device is counted by the counting means as in the invention according to claim 4, and when the counted number of symbol fluctuations reaches a preset number of symbol fluctuations, a high value is obtained. If the mode is shifted to the probability mode, the larger the number of symbol fluctuations of the ordinary symbol display device, the greater the number of winning balls to the first-type starting winning opening, and the greater the probability of occurrence of the "big hit" occurrence of the special symbol display device. Become.

Further, as in the fifth aspect of the present invention, the count value of the number of symbol changes of the ordinary symbol display device is all irrespective of whether the symbol displayed on the ordinary symbol display device or the special symbol display device is hit or not. If the addition is performed, the high mode probability that the first-class start winning opening will be in the winning acceptance state becomes earlier, so that the player has a high expectation and is made to want to continue the game.

[0040]

[Table 3]

In the control flowchart of FIG. 4, the game ball fired in S10 is replaced with the gates 32, 33.
If the player wins any one of the winning ports provided on the game board 10 without passing through (S12 “NO”, S1
6) In addition, as shown in the above-mentioned S26, when the first-class start winning opening 4 is not won (S26 “NO”),
The number of prize balls set for each winning port is paid out (S1).
6 "YES", S18), if no prize is won, the result is "losing" (S20), and the paper is discharged from the discharge port 39.

In the case where the normal symbol display device 34 does not display the "hit" in S22 (S22 "N
O "), and when the special symbol display device 2 does not display any of the" big hit "symbols shown in Tables 2 (a) and 2 (b) in S28 (" NO "in S30).
Is called "losing" (S34), and the game situation does not change.

FIG. 5 is a flowchart showing the operation of the condition device when a "big hit" is generated by S32 shown in FIG. When the condition device is activated in accordance with the occurrence of the "big hit", the special winning combination 6 which is a special electric accessory is opened (S40), and a special game situation associated with the "big hit" is started. Either 20 seconds have elapsed since the opening of the special winning opening 6 or 10 game balls were won in the special winning opening 6 (S).
42 "YES"), or when one game ball passes through the specific area winning opening 7 (S44 "YES"), even if it is within the opening time or even if 10 winnings do not win in the special winning opening 6. It is closed (S46).

If the game ball does not pass through the specific area winning opening 7 shown in S44 ("NO" in S44), the above operation is repeated until the game situation shown in S42 and S44 occurs. And the occurrence of this "big hit"
If it is generated by any of the normal symbols shown in Table 2 (a), the number of times of opening of the special winning opening 6 is 16, and
If it is caused by any of the specific symbols shown in (b), the above operation is repeated up to 14 times (S48 "N
O "). Then, the operation of the condition device is terminated when the number of times reaches 16 (or 14) (S50).

However, the lottery probability that the "big hit" symbol is displayed on the next special symbol display device 2 is shown in Table 2 (a).
If the normal symbol shown in is displayed, a low probability (1/3
37), when the specific symbols shown in Table 2 (b) are displayed, the process moves to the high probability (5/337).

FIG. 6 is a control flowchart in the case where the lottery probability of the ordinary symbol display device 34 in the present gaming machine shifts from the low probability mode to the high probability mode. As described above, the normal symbol display device 34 is set in the low probability mode in which the lottery probability at which a “hit” occurs is set to be low and the high probability mode in which the lottery probability is set to be high. At the time of (input), the low probability mode, which is the initial setting, is set (S60). Also, the normal symbol display device 34
Is updated (N =
0) is performed (S60).

The game ball that has been hit is played on the game board 1
When the vehicle passes through one of the left and right gates 32 and 33 provided at 0 (S62 “YES”), the left and right gate switch 6
When the passage is detected at 2, 64 and the ordinary symbol display device 34 starts to change (S64), it stops after 6 seconds have elapsed and displays any symbol from "0" to "9" ( S66). Here, when the game ball does not pass through the left and right gates 32 and 33 (S62 "NO"), a game situation such as a fluctuation of the symbol display device 34 does not normally occur.

Further, the fluctuation of the ordinary symbol display device 34 stops, and the number of stops is counted (S6).
8). This count may be such that the symbol displayed by stopping the ordinary symbol display device 34 may be “hit” or “losing”, and only the number of times the ordinary symbol display device 34 fluctuates and stops is sequentially added to the count value N. It is set to go.

Then, the count value N of the variable symbol stop count of the ordinary symbol display device 34 reaches a preset count value (for example, N = 100 times) (S70 "YES").
The mode of the ordinary symbol display device 34 shifts from the currently set low-probability mode (initial setting) to the high-probability mode, and the lottery probability at which a “hit” occurs is from 5/10 to 9
/ 10 and set (S72).

As shown in S70, while the count value N of the number of times the variable symbol is stopped by the ordinary symbol variable device 34 is less than a preset count value (eg, N = 100) (S70 "NO"). Repeats the counting. In addition, the special symbol display device 2 repeats the start and stop of symbol change by the number of game balls that have won the first-type start winning opening 4, for example, while the special symbol display device 2 is changing symbols, the ordinary symbol display device 34. Even if the number of winnings in the first-type starting winning opening 4 following the “winning” symbol increases (for example, five or six), the game balls that have won the first-type starting winning opening 4 are: All are counted.

FIG. 7 is a control flowchart for counting the symbol change stop of the ordinary symbol display device 34 shown in FIG. As described above, the normal symbol display device 34 of the gaming machine sets the low probability mode, which is the initial setting, at the start of the game (power-on) (S90), and first, stops the symbol change in the ordinary symbol display device 34. The count value N of the number of times is updated.

Then, every time the game ball passes through the left and right gates 32 and 33, the symbol change of the ordinary symbol display device 34 is started (S92), and stopped after 6 seconds from the start of the symbol change. Is displayed (S93). Here, the symbols displayed on the ordinary symbol display device 34 are selected using a random counter (not shown).

The random counter sequentially counts a counter value from an initial value "0" to a return value (for example, "9") in a time cycle. For each of the random counter values “0” to “9”, the symbols “0” to “9” displayed on the normal symbol display device 34 are set correspondingly (for example, the random counter value). “2” corresponds to the symbol “2” displayed on the ordinary symbol display device 34). Then, a random counter value is selected when 6 seconds have passed since the ordinary symbol display device 34 started symbol variation. At this time, the symbol corresponding to the selected random counter value is displayed on the ordinary symbol display device 34.

In the present embodiment, the count of the number of times the symbol fluctuation is stopped by the ordinary symbol display device 34 is determined by detecting a signal in the selection operation when the ordinary symbol display device 34 selects a random counter value, and counting the count value N. Is incremented by one. Since this addition detects a signal associated with the random counter value selection, all the symbol fluctuation stop counts are counted regardless of the “hit” or “miss” of the symbol displayed on the symbol display device 34. (S9
4)

When the count value of the symbol change stop number of the ordinary symbol display device 34 reaches a preset value (for example, N = 100 times) (S95 "YES"), the mode of the ordinary symbol display device 34 becomes The mode is shifted to the high probability mode and set (S96). However, S while the count value N is less than a preset value (for example, N = 100 times) (S9
5 "NO"), the counting is repeated again.

As shown in S76, the count value N
Reaches a preset value (for example, N = 100 times) and the high-probability mode is set.
Is updated (S97), N = 0, and a new count is started.

It should be noted that, as shown in FIG. 6, the count of the number of times the variable symbol stops on the ordinary symbol display device 34 is determined while the condition device is operating after a "big hit" occurs on the special symbol display device 2. Is set so that the counting operation is not performed and the counting operation is restarted after the operation of the condition device is completed. However, this count is not uniform,
The counting operation may be performed during the operation of the condition device.

FIG. 8 is a control flowchart when the ordinary symbol display device 34 has shifted to the high probability mode. As shown in FIGS. 6 and 7, when the count value N of the variable symbol stop count of the ordinary symbol display device 34 reaches a preset value (for example, N = 100 times), the mode of the ordinary symbol display device 34 becomes The high-probability mode is set by shifting from the low-probability mode up to that point (S100), and the count value N obtained by counting the number of times of the variable symbol stop of the ordinary symbol display device 34 is updated to "0" (S102).

The counting of the number of times the variable symbol is stopped by the ordinary symbol display device 34 is stopped while the high probability mode is set. The stop of the counting of the variable symbol stop count is not uniform, and the symbol stop count may be counted even while the high probability mode is set.

When the high-probability mode is set, the lottery probability for displaying the "winning" symbol by the ordinary symbol variation device 34 varies from 5/10 to 9/10 (S104).
Then, while the high probability mode is set, the game ball wins in the first-type starting winning opening 4 (S106: “YE”).
S "), one winning ball is paid out for one winning ball (S108).

Further, a game ball wins in the first kind start winning opening 4 and each of the symbols 2a, 2b, 2c of the special symbol display device 2.
5.0 seconds have elapsed since the start of the fluctuation, and the displayed symbol is one of the "big hit" symbols shown in Tables 2 (a) and 2 (b) (S95). "YE
S ") and" big hit "occur (S110" YES ")
Then, the condition device operates as shown in FIG. 5 (S112).

When the "big hit" ends as shown in S110 (S114 "YES"), the setting of the high probability mode which has been set so far ends (S11).
6) The mode of the ordinary symbol display device 34 returns from the high probability mode to the low probability mode.

When the game ball does not win in the first-type starting winning opening 4 shown in S106 (S106 "NO"), the special symbol display device 2 starts to change as shown in S110. However, the combination of the "big hit" symbols shown in Table 2 (a) and (b) was not displayed (S110 "N
In the case of "O"), it is called "losing" (S118), and the game is continued while maintaining the high probability mode until a "big hit" occurs. Further, as shown in S114, until the number of continuous operation of the accessory due to the occurrence of the "big hit" ends ("NO" in S114), the number of continuous operation of the accessory ends in the high probability mode. The above operation is continued until the above.

That is, the probability mode of the ordinary symbol display device 34 is set to the low probability mode when the power is turned on at the start of the game, and thereafter, the count value N of the variable symbol stop count of the ordinary symbol display device 34 is set in advance. Value (eg N = 10
0) and the mode shifts to the high probability mode. This high-probability mode is maintained until a “big hit” occurs, after which a “big hit” occurs, the operation ends, the setting of the high-probability mode ends, and the mode returns to the low-probability mode. Is set. As a result, a high-probability mode in which a “big hit” is likely to occur appears at a time when the player cannot predict.

When the number of times of opening the first-type start winning opening increases due to an increase in the probability that the "winning" symbol is displayed on the ordinary symbol display device by shifting to the high-probability mode, the first-type symbol is accordingly increased. The possibility of winning in the starting winning opening is increased. Along with this, the number of lotteries of the special symbol display device increases, and the possibility of occurrence of “big hit” increases. In addition, the number of times the normal symbol display device fluctuates is counted irrespective of whether the symbol displayed on the ordinary symbol display device hits or misses, so that the ordinary symbol display device shifts to the high probability mode quickly.

Further, when the ordinary symbol display device shifts to the high-probability mode, the number of game balls winning the first-type starting winning opening increases, and during the symbol change of the special symbol display device, the number of the game balls changes. The number of game balls that have won the starting winning opening may be as many as five or six, but all of them are used for the lottery of the symbol change of the special symbol display device without being invalidated.

The present invention is not limited to the above-described embodiment at all, and various modifications can be made without departing from the gist of the present invention. For example, the switching control between the low-probability mode and the high-probability mode in the above-described embodiment, and the setting contents thereof, the setting of the game situation that triggers the change of the mode, and, in the present embodiment, the counting method is a normal symbol display device. Although the variable symbol stop count is used, these additional changes and the like can be appropriately made, thereby further increasing the amusement and further enhancing the interest of the player. In particular, when the lottery probability of the ordinary symbol display device shifts to the high probability mode,
The symbol fluctuation time is also shortened (for example, shifting from 6 seconds to 5.8 seconds), or the opening time of the first-type start winning opening of the electric winning device is increased and the number of times of opening is increased (for example, A gaming machine in which (for example, 0.3 seconds × 1 time is changed to 0.7 seconds × 3 times) and the like can also produce a game with an interesting effect.

[0068]

According to the lottery probability control device of the symbol display device in the pachinko game machine according to the first aspect of the present invention, the lottery probability of the second ordinary symbol display device provided on the game board is determined during the game. By shifting from the low-probability mode to the high-probability mode, the number of winnings in the first-type start winning opening of the electric winning device increases, and the probability that a “big hit” occurs on the first symbol display device increases accordingly, so that the game The player is not only interested in the lottery of the "big hit" symbol generation of the first symbol display device, but also pays attention to the fluctuation of the lottery probability of the second symbol display device, and will continue the game with a sense of expectation.
Then, in this case, the winning balls to the first-type starting winning opening are all counted and provided for the lottery of the "big hit" occurrence of the first symbol display device, so the "big hit" at an earlier opportunity accordingly. It is even more interesting to be able to have the expectations that arise.

And, as in the invention according to claim 2,
The transition to the high probability mode is triggered by the case where the count of the symbol change stop number of the second symbol display device satisfies a preset number. The transition to the probability mode can be foreseen, and the interest in the game is further aroused.

According to the third aspect of the present invention, the first-type winning prize opening of the electric winning device is opened by the determination of the "winning" symbol of the ordinary symbol display device, and the first-type winning prize opening is provided in the first-type winning prize opening. In the game contents that the special symbol display device starts symbol change by the winning of the game ball and a large hit is generated by the stop symbol, a large amount of prize balls are paid out to the player. When the number of symbol fluctuations reaches a predetermined number, the probability of occurrence of the “hit” increases, so that the number of winning balls to the first-class start winning opening also increases, and the timing of the “big hit” symbol occurrence of the special symbol display device accordingly increases Expected to come early.

Also, in this case, the timing of occurrence of the "hit" comes by counting the number of symbol fluctuations of the ordinary symbol display device as in the invention according to the fourth aspect. Expectation is great.

Further, as in the fifth aspect of the present invention, since the number of symbol changes of the ordinary symbol display device is counted regardless of the judgment of the hit or miss of the displayed symbol, the symbol variation number is quickly increased. It is possible to have a new sense of expectation that the mode will be shifted to, so that the player's satisfaction is increased and a game with even higher amusement can be provided.
