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, an arrangement ball machine, a play ball game machine, and a spinning type game machine.

[0002]

2. Description of the Related Art In a ball-and-ball game machine such as a pachinko machine, a symbol display means having a plurality of symbol display portions in addition to a prize means such as a normal prize means and a large prize means in a game area of a game board;
A symbol change requesting means such as a start winning opening is provided, and if there is a symbol change request from the symbol change requesting means, the symbol of each symbol display portion of the symbol display means is changed for a predetermined time, and the stop symbol after the change is changed. When a combination of predetermined specific symbols (big hit symbols) is obtained, a specific state advantageous to the player is generated.

[0003] Once a specific state occurs, the variable prize means such as the large prize means is repeatedly opened a predetermined number of times, or after a game ball which has won the predetermined prize means passes through a special operation area therein. A great profit is returned to the player by repeatedly opening the variable winning means a predetermined number of times for each winning on the condition that the game ball wins the particular winning means.

For example, when the symbols displayed on each symbol display portion of the symbol display means are ten types of numeral symbols from 0 to 9, and symbol "7" among them is set as a specific symbol, the symbol display portion of each symbol display portion is displayed. The combination in which all the stop symbols are “7” of the specific symbol, that is, a big hit when the symbol displayed on the symbol display means is “7, 7, 7”.

In the case where the symbol of each symbol display section of the symbol display means fluctuates in response to a symbol change request, conventionally, 10 to 0 to 9
The symbols in each symbol display unit fluctuate according to a symbol group in which each number symbol is one unit, and after fluctuating for a predetermined time, select one of the symbols in each symbol group and use each symbol display unit in the symbol. The method of stopping the symbol is adopted.

[0006]

In the conventional ball game machine, the symbols displayed on each symbol display section of the symbol display means are:
It changes in a fixed order according to a symbol group in which ten numeral symbols from 0 to 9 are defined as one unit, and since the number of types of numeral symbols in the symbol group is always constant at ten, from the start of fluctuation to the stop Even if a method such as changing the fluctuation pattern is adopted, it becomes very monotonous as a whole, and the pattern fluctuation itself cannot sufficiently enhance the interest of the player.

[0007] In view of the above-mentioned conventional problems, the present invention eliminates the monotony of symbol fluctuation and further enhances the interest of the player, and enhances the player's expectation of stopping at a specific symbol. The purpose is to provide a machine.

[0008]

[0009]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIGS. 1 to 4 illustrate a first embodiment of the present invention. In FIGS. 1 and 2, reference numeral 1 denotes a game machine main body, which has a front frame 2 pivotally connected to be freely opened and closed. A game board 4 is detachably attached to the front frame 2 from the back side corresponding to the window hole 3, and a glass door 5 and a front panel are provided on the front side of the game board 4.
6 are arranged to be openable and closable. The front plate 6 is provided with an upper plate 7 for storing game balls for firing. Front frame 2
A lower plate 8 for storing surplus spheres and a firing handle 10 of a firing means 9 are provided at the lower part of the lower part.

As shown in FIG. 2, a guide rail 11 is mounted on the game board 4 in a ring shape.
A central display device 13 and a variable starting port 1 in a game area 12 inside 11
4. A plurality of game parts such as a variable winning opening 15, a normal winning opening 16 to 18, a passing gate 19 and the like are arranged.

The central display device 13 has first symbol display means 20 composed of liquid crystal display means and the like, and second symbol display means 21 disposed above the first symbol display means 20. The first symbol display means 20 is 1
Or more, for example, multiple (three in the horizontal direction) symbol display unit
20a, 20b, 20c are provided in the left-right direction, and their respective symbol display portions 20a,
20b and 20c are designed to emit, for example, ten types of numeric symbols from "0" to "9". In addition, the first symbol display means 20 displays the symbols on the symbol display sections 20a, 20b, 20c for a predetermined time (for example, about 5 to 30 seconds) by random number control on condition that a game ball wins in the variable starting port 14. It is configured to fluctuate and stop.

The second symbol display means 21 has one symbol display portion, and emits and displays ten types of numeric symbols from "0" to "9". The second symbol display means 21
Is configured such that, on condition that the pass gate 19 detects the passage of a game ball, the display symbol of the symbol display portion fluctuates for a predetermined time (for example, about 10 to 30 seconds) by random number control and stops. . The normal fluctuation time of the second symbol display means 21 is set longer than the fluctuation time of the first symbol display means 20. This fluctuation time may be different depending on the fluctuation pattern.

The variable starting port 14 is an electric tulip or the like having a pair of left and right opening / closing claws 14a which can be opened and closed.
The opening / closing claw 14a is opened for a predetermined time (for example, about 0.5 seconds) when the stopped symbol after the fluctuation of the symbol display means 21 hits the symbol. The variable starting port 14 constitutes a first symbol change requesting means, and the passing gate 19 constitutes a second symbol change requesting means.

The variable winning opening 15 has an opening / closing plate 15a which can be opened and closed between an open state which is advantageous to the player and a closed state which is disadvantageous to the player, and the stop symbol after the first symbol display means 20 is changed is a specific symbol. For example, when a big hit symbol such as “7/7
a opens to the front. A specific area 22 is provided in the variable winning opening 15, and when a winning ball passes through the specific area 22, a specific state by a so-called big hit is continued.

The variable winning opening 15 closes the opening / closing plate 15a when a predetermined time has elapsed after opening or when a predetermined number (for example, 10) of game balls have won, and the game balls pass through the specific area 22. On the condition that the maximum number of times (for example, 1
(6 times). One or more (eg, 2)
) Ordinary prize holes 17, 18 are provided respectively.

FIG. 3 is a block diagram illustrating a control system. 23 is a first random number generating means, which repeatedly generates a predetermined random number such as a jackpot / missing decision random number, a stop symbol determining random number, etc., for example, the stop symbol of the first symbol display means 20 is a jackpot symbol. Big hit probability is 1/2
In the case of 50, a random number from 0 to 249 for determining a jackpot / missing is generated.

Reference numeral 24 denotes first symbol variation control means,
Departure determination unit 25, symbol fluctuation stop processing unit 26, and reach determination unit 27
And a symbol deletion control unit 28. The jackpot / missing determination unit 25 draws a jackpot / missing determination random number of the first random number generating means 23 in response to a symbol change request due to a winning of a game ball to the variable starting port 14, and determines a jackpot / missing from the random number. It is configured to perform.

The symbol change stop processing unit 26 changes the symbols of the symbol display units 20a, 20b, and 20c of the first symbol display means 20 according to the symbol group in response to a symbol change request by winning a game ball to the variable starting port 14. The function of changing the scroll and the random number for determining the stop symbol of the first random number generating means 23 are randomly selected according to the request for the change, and the symbols of each symbol group can be visually checked when a predetermined time has elapsed from the start of the change. It has a function of stopping the symbol change so that each symbol display section 20a, 20b, 20c displays a symbol corresponding to the random number after a change in speed. Note that the symbol change stop processing unit 26 displays the symbol change of the first symbol display means 20 on the left symbol display unit 20a and the middle symbol display unit 20b.
, And stop in the order of the right symbol display section 20c.

The reach determining section 27 includes three symbol display sections 20a,
Of the symbols 20b and 20c, the symbols on the symbol displays 20a and 20b except for the symbol display 20c, ie, the symbols on the left symbol display 20
When the stop symbol between the symbol a and the middle symbol display section 20b becomes a specific symbol, it is determined as reach. If the left symbol display section 20a and the middle symbol display section 20b stop at a specific symbol, there may be an advantageous state after that depending on the stopped symbol of the right symbol display section 20c. The determination unit 27 has a function as a determination unit that determines that the symbol in the course of changing the symbol may be in a state advantageous to the player.

The symbol deletion control unit 28 temporarily deletes some symbols other than the specific symbol from the symbol group displayed on the right symbol display unit 20c when the reach determination unit 27 determines that the reach is reached. It has a symbol deletion function, and issues a symbol deletion command to the symbol change stop processing unit 26 to temporarily delete some symbols from the symbol group. For example, normally, as shown in FIG. 4A, a symbol group of the right symbol display section 20c is exemplified.
1 from 0 to 9 displayed on each symbol display section 20a, 20b, 20c
In the case where 0 types of numeric symbols are used as a symbol group of one unit, as shown in FIG. 4B, the two numeric symbols “0” and “1” are deleted.

The first symbol variation control means 24 stores up to a predetermined number (for example, four) of winnings in the variable starting port 14 during the variation operation of the first symbol display means 20, and within the range of the stored number. Thus, the fluctuation / stop is continued after the fluctuation operation of the first symbol display means 20 is completed.

Reference numeral 29 denotes a second random number generating means for repeatedly generating a hit / miss determination random number. Numeral 30 denotes a second symbol variation control means, on the condition that the passing gate 19 detects the passage of the game ball, randomly selects a random number generated by the second random number generating means 29 at that time, and The symbol is fluctuated for a predetermined time and stopped at a predetermined stop symbol.

An opening / closing control means 31 determines whether or not the stop symbol of the second symbol display means 21 which fluctuates and stops under the control of the second symbol variation control means 30 is a predetermined hit symbol, for example, "3". At the time of a predetermined winning symbol, the variable starting port 14 is opened for a predetermined time. Note that the hit probability of the second symbol display means 21 is set to a high probability of about 1/2 to 1/3, and if a game ball passes through the passing gate 19, the variable starting port
14 opens and closes relatively frequently with a probability of about 1/2 to 1/3 thereof.

Reference numeral 32 denotes a specific state generating means. The jackpot / missing determination section 25 makes a jackpot determination, and all the symbols stopped after the symbol display sections 20a, 20b, 20c of the first symbol display means 20 are changed to the specific symbol " In the case of the combination of "7", this is for generating a specific state advantageous to the player. Note that the specific state generating means 32 opens the opening and closing plate 15a of the variable winning opening 15 after the occurrence of the specific state, and when a predetermined time has elapsed after the opening, or when a predetermined number of game balls have won, the opening and closing plate 15a
And has a function of controlling the opening and closing operations to be continued up to a maximum of a predetermined number of times on condition that the game ball which has won while opening is passing through the specific area 22.

In the above-mentioned ball game machine, when the firing handle 10 of the firing means 9 is operated during a game, the game balls on the upper plate 7 are supplied to the firing unit one by one in conjunction with the firing operation of the firing means 9. Hit the game ball with a hammer and guide rail
We fire sequentially to game board 4 side along 11. After the game ball fired on the upper side of the game board 4 enters the game area 12 of the game board 4, the variable start port 14, while falling along the board surface,
The player wins the normal prize openings 16 to 18 or falls down while passing through the passage gate 19.

When the game ball passes through the passage gate 19, the second
The random number generated by the random number generating means 29 is randomly selected, and the second symbol change control means 30 changes the symbol displayed on the second symbol display means 21 by the random number control. When the stop symbol after the change of the second symbol display means 21 becomes a hit symbol such as "3", the opening / closing claw 14a of the variable starting port 14 is opened by the opening / closing control means 31 for a predetermined time, and the variable start Gaming balls in the mouth 14 are easier to win.

When a game ball wins in the variable starting port 14 and there is a symbol change request, the symbol change stop processing unit 26 operates and is displayed on each symbol display unit 20a, 20b, 20c of the first symbol display means 20. The symbols are scrolled in accordance with the symbol group. At the beginning of the change, the display symbols of the symbol display sections 20a, 20b, 20c fluctuate at such a high speed that they cannot be visually confirmed or are difficult to confirm, and gradually fluctuate slowly according to a predetermined stop pattern.

On the other hand, the random number generated by the first random number generating means 23 is randomly selected on condition of the symbol change request, and the jackpot / missing judging section 25 judges whether the jackpot is a big jackpot by the random number control. Then, after the determination, the symbol variation stop processing unit 26 determines a symbol to be stopped by randomly selecting the symbol for determining the symbol of the first random number generating means 23, and determines the variation at a speed at which the symbols of each symbol group can be visually confirmed. After that, the operation shifts to a stop operation, in which the left symbol display section 20a, the middle symbol display section 20b, and the right symbol display section 20c are stopped in this order.

At this time, when the jackpot / missing determination unit 25 determines that the symbol is a big hit, the symbols displayed on the symbol display units 20a, 20b, and 20c of the first symbol display means 20 always stop after reaching the reach state. The symbols displayed on the symbol display units 20a, 20b, and 20c may stop after reaching the reach state even when the disconnection determination unit 25 determines that the symbols have come off. In addition, the stop symbol at the time of this departure is also determined by lottery of the random number for stop symbol determination.

For example, the left symbol display section 20a and the middle symbol display section 20
If b stops at the specific symbol “7” and reaches the reach state, before the symbols on these symbol display portions 20a and 20b stop,
Simultaneously with or immediately after the stop, the reach determination unit 27 performs the reach determination, and the symbol deletion control unit 28 issues a symbol deletion command for temporarily deleting the symbols “0” and “1”. Therefore, the symbol change stop processing unit 26 temporarily deletes the symbols “0” and “1”, that is, the eight types “2” to “9” as shown in FIG. The numerical symbols are changed and controlled as one symbol group.

Accordingly, the symbols displayed on the right symbol display section 20c during the change are to scroll and display eight types of numeric symbols from "2" to "9" repeatedly. Since the two symbols “0” and “1” have been deleted, the appearance probability that the stopped symbol in the right symbol display section 20c becomes “7” of the specific symbol is apparently 1/10 from 1/10 of that time. 8 to increase the player's sense of expectation for the occurrence of a jackpot. However, the jackpot occurrence probability does not change.

The symbol may be deleted either during fluctuation at a speed (high speed) that cannot be confirmed visually or during fluctuation at a speed (low speed) that can be confirmed. In the former case,
The left symbol display section 20a and the middle symbol display section 20b are "0" ~
While the ten types of “9” are scroll-displayed as one unit of symbol group, the right symbol display section 20c displays “2” to “9”.
Is changed to a symbol group having one unit as a unit, and in the latter case, during the change at a low speed, a symbol group having ten types of “0” to “9” as one unit is displayed in the middle of a scroll display. 2 "
The symbol group changes to a symbol group in which ~ 9 is set as one unit. As a result, in any case, the conventional monotony of the symbol fluctuation can be eliminated, and the interest of the player can be further improved.

When the stop symbol after the change of the first symbol display means 20 becomes a big hit symbol, a specific state is generated by the specific state generating means 32, and the opening / closing plate 15a of the variable winning opening 15 is opened, and along the board surface. The falling game balls can easily enter the variable winning opening 15. Then, when a predetermined time elapses after the opening of the variable winning opening 15, or when a predetermined number (for example, 10) of game balls wins in the variable winning opening 15, the opening / closing plate 15a is closed.

If the game ball that has won while the variable winning port 15 is open passes through the specific area 22, the variable winning port 15 continues to open and close up to a predetermined number of times (for example, 16 times). As a result, a large number of game balls are won in the variable winning opening 15, and a great profit can be returned to the player. In addition to the symbol change of the first symbol display means 20, the player's interest in the game further increases.

FIG. 5 illustrates a second embodiment of the present invention,
It has a number-of-deleted symbols increasing function in which the number of symbols to be deleted increases with time. That is, the symbol deletion control unit 28 of the first symbol change control unit 24 includes a deleted symbol number increasing program configured to increase the number of symbols to be deleted with time with the passage of time.
Determines the reach state of the first symbol display means 20,
Part of the symbol group displayed on the right symbol display section 20c (for example, 1
Is issued in accordance with a program for increasing the number of symbols to be deleted over time, and a predetermined number of symbols (for example, one symbol) are displayed on the right symbol display section 20c. ).

In this embodiment, after the first symbol display means 20 shifts to the reach state, when the display symbol of the right symbol display section 20c changes for the first time, the change is shown in FIGS. 6A to 6B. As described above, one symbol "1" is deleted to be a nine symbol group, and one symbol "2" is further deleted at the time of the second scroll change to be an eight symbol group ((FIG. 6 ( C)), and at the time of the third scroll change, one symbol "3" is further deleted to form a seven symbol group (see FIG. 6D).

Therefore, the right symbol display section 20 is displayed as time elapses.
Since the number of symbols to be deleted from the symbol group displayed in c increases, the appearance probability that the stopped symbol in the right symbol display section 20c becomes “7” of the specific symbol gradually increases with the passage of time, and the player's It is possible to further increase the sense of expectation for occurrence of a jackpot.

The number of symbols to be deleted may be sequentially increased until the symbol change of the right symbol display section 20c is completed, or if the number of symbols to be deleted increases to a certain number, no matter how many times the scroll is changed thereafter, no more. May not delete the symbol. The number of symbols to be deleted may be increased under conditions other than the number of times of scroll fluctuation. For example, it is possible to use a timer and increase the number of deletions every time a predetermined time elapses.

FIG. 7 illustrates a third embodiment of the present invention,
This is provided with a specific symbol increasing function for temporarily increasing the specific symbol of the symbol group displayed on the right symbol display section 20c during the change. That is, the first symbol variation control unit 24 includes a symbol hit control unit 25, a symbol variation stop processing unit 26, a reach determination unit 27, a symbol deletion control unit 28, and a symbol increase control unit for a specific symbol.
It has 34.

The symbol increasing control unit 34 has a specific symbol increasing function for temporarily increasing the number of symbols of the specific symbol by the same number or less than the number of deleted symbols from which symbols are removed by the symbol deleting control unit 28. The symbol increase command is issued to the symbol change stop processing unit 26 to replace all or a part of the deleted symbol with a specific symbol. For example, as shown in FIG. 8 (A) from the symbol group of FIG. 8 (A), two off symbols “1” and “2” are deleted by the symbol deletion command of the symbol deletion control unit 28, and the symbols are increased. In response to the symbol increase command of the control unit 34, the number of the specific symbol "7" is increased by two to three, and the two deviating symbols "1" and "2" are temporarily changed to two specific symbols "7". Replace.

In the example shown in FIG. 8, the right symbol display section
The appearance probability that the stop symbol of 20c is “7” of the specific symbol is
Since the appearance is as large as 3/10, the expectation of the player for the occurrence of the jackpot is further increased. In this case, it is desirable to change the symbol arrangement at the time of scroll change so that the specific symbols are distributed substantially evenly in all the symbol groups.

It should be noted that the third embodiment may employ a function reverse to the number-of-deleted symbols increase function of the second embodiment, so that the number of specific symbols sequentially increases by replacement as time passes. .

Although the embodiments of the present invention have been described in detail, the present invention is not limited to the embodiments, and various changes can be made without departing from the spirit of the present invention. In each embodiment, three symbol display units 20a, 20b, 20
Although the symbol control of the first symbol display means 20 having c is illustrated, the first symbol display means 20 may be one having at least one symbol display unit. Also, the second symbol display means 21 can be similarly implemented.

In a gaming machine equipped with, on the condition that the changing symbol may be in an advantageous state for the player, another symbol group displayed on the changing symbol display section 20a, 20b, 20c A design replacement function for replacing all or a part of the design with a specific design may be provided. A symbol increasing function for temporarily increasing the number of specific symbols in the symbol group displayed on the changing symbol display section 20c may be provided. Also, a function of increasing the number of deleted symbols, which increases the number of deleted symbols of other symbols with the passage of time, may be provided.

The symbol display means 20, 21 comprises a plurality of symbol display units.
20a, 20b, 20c, a plurality of symbol display units 20a, 20b, 20c
Of the symbol display units 20a, excluding the one symbol display unit 20c,
The symbol replacement function or the symbol increasing function may be operated on condition that the stopped symbol of 20b becomes a specific symbol. Further, the symbol display units 20a, 20b, and 20c scroll the symbols of the symbol group at a speed at which the symbols displayed on the symbol display units 20a, 20b, and 20c can be visually confirmed before the symbol change stops. It may be.

Each symbol display section 20a, 20 of the first symbol display means 20
The symbols displayed in b and 20c are numerical symbols in the embodiment, but are not particularly limited to numeric symbols, and any symbol can be freely selected. The number of design groups,
The type of the specific symbol, the number of symbols to be deleted when a symbol other than the specific symbol is deleted, and the increase number when the number of the specific symbol is increased are merely examples.

When the stop symbol of the right symbol display section 20c stops at a non-specific symbol other than the specific symbol, or when the symbol stops at the specific symbol, a part of the symbol of the symbol group is deleted once and then deleted. It is also possible to revive the design and restore it. The same applies when the number of specific symbols increases.

Further, when a symbol other than the specific symbol is temporarily deleted, or when the number of the specific symbols increases, the first symbol display means is displayed.
A notification means for notifying the player of the fact by changing the background color of the 20 symbol display portions 20a, 20b, 20c, or by emitting an appropriate light-emitting body may be provided. Symbol display section 20a,
