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 sparrow ball game machine, and a torso game machine.
In particular, it relates to the symbol control device.

[0002]

2. Description of the Related Art In a ball-and-ball game machine such as a pachinko machine, in addition to a normal prize means, a variable prize means, etc., in a game area of a game board,
Special symbol display means for displaying a plurality of special symbols (symbols for special games), and special symbol starting means for detecting a game ball and issuing a symbol starting request are provided, and a symbol starting request from the special symbol starting means is provided. On the condition that there is a condition, a plurality of special symbols of the special symbol display means are varied for a predetermined time by the special symbol variation control means, and a special symbol pattern in which a stop symbol after the variation is a predetermined combination of specific symbols ( When a big hit is achieved, a special game state that is advantageous to the player is generated, for example, the variable winning means performs the opening and closing operation a plurality of times.

[0003] The special symbol display means is usually constituted by liquid crystal display means or the like, and displays a plurality of symbol display portions on the display screen by framing or the like, and numeral symbols and character symbols are displayed in each symbol display portion. And other identifiable special game symbols are displayed.

[0004] When there is no symbol starting request from the symbol starting means for a predetermined time, for example, a demonstration image and other images are displayed on the display screen of the liquid crystal display means, and the game ball wins the special symbol starting means. Thus, when there is a symbol start request, the display screen displays the outline of the symbol display section and the like, and adopts a display mode in which the special game symbols in each symbol display section are changed for a predetermined time.

[0005]

In the conventional special symbol display means, the special game symbol in each symbol display section always changes in a predetermined size, a predetermined scroll, and other fluctuation modes according to the random number control of the symbol fluctuation control means. It is common to do. For this reason, there is a drawback that the effect of the effect at the time of symbol change is poor, and the interest of the player cannot be aroused.

[0006] Also, among the plurality of types of special symbols that are variably displayed on the symbol display portion during symbol variance during the reach change state, there is a type in which a symbol corresponding to the special display mode is enlarged and displayed. . In this case, it is possible to expect a dramatic effect that stimulates the player's sense of expectation at the time of the reach change, as compared with the case where a special symbol of a fixed size is always displayed.

However, in the method of enlarging and displaying the symbols, since the other symbols which do not correspond to the special display mode have the same size as the special game symbols which correspond to the special display mode, it is necessary to enlarge the changing symbol. There are drawbacks that cannot be emphasized.

That is, when the size of the special symbol normally displayed on each symbol display section is increased so that the player can easily identify and determine the type of the special symbol, the symbol of the type corresponding to the special display mode is used. Needs to be even larger. Therefore, in the conventional enlargement method, it is difficult to extremely change the size between the type of the symbol corresponding to the special display mode and another type of the symbol, and there is a certain restriction on the effect of the effect.

[0009] Also, among a plurality of types of symbols, the number of symbols of the type corresponding to the special display mode is one, while the number of other types of symbols is much larger. In the method of displaying only the type of symbol that is large, for example, when scrolling each symbol, there is no large speed change between the type of symbol corresponding to the special display mode and the other type of symbol. Therefore, it is also difficult to produce an effect in which the entire pattern of another type not related to the special display mode is rapidly changed so that when the type of the pattern corresponding to the special display mode appears, the pattern appears to stop for a moment. .

In view of such a conventional problem, the present invention displays a symbol of a size that can be easily identified by a player, and displays a symbol of a type corresponding to the special means mode in terms of size and variation speed. An object of the present invention is to provide a gaming machine that can be emphasized by both, stimulates a player's sense of expectation, and increases interest.

[0011]

According to the present invention, there is provided a symbol starting means.
14, and a symbol display means 21 having one or a plurality of symbol display portions 22 to 24 for displaying symbols 22a to 24a for special games,
On the condition that there is a symbol start request from the symbol start means 14, the symbol 22a for the special game of the symbol display portions 22 to 24
And a symbol variation control means 31 for varying and stopping the symbols for a predetermined time, and the symbols 22a to 24a for the special game, which are stopped and displayed on the symbol display units 22 to 24 after the variation, have a predetermined special display mode. In the gaming machine provided with a special game state generating means 36 for generating a special game state advantageous to the player on condition that the symbol change control means 31 is stopped and displayed on the symbol display units 22 to 24. When the special game symbols 22a to 24a are in a fluctuating state following the special display mode, a plurality of types of the special game symbols 24a that are fluctuated and displayed on the fluctuating symbol display unit 24 are displayed. Among them, it has a function capable of reducing at least a part of a symbol other than the symbol corresponding to the special display mode.

Provided that the special symbol starting means 14 detects a game ball, the special symbols of each symbol display section 22 to 24 are controlled by random number control.
22a to 24a fluctuate for a predetermined time and stop as described later.

The special symbol display means 21 constitutes a symbol display means for displaying a symbol for a special game,
In this embodiment, special symbols 22a to 24a are symbols for special games. The special designs 22a to 24a can use numeral designs, alphabet designs, character designs, and other designs. In this embodiment, 10 types of numbers from 0 to 9 are used, and the 10 types of numbers are used. The symbols scroll sequentially.

The liquid crystal display means 13 is provided with a normal winning means 16 and a normal symbol display means 25 on the upper part thereof. The ordinary symbol display means 25 has one or a plurality of, for example, one symbol display section, and on condition that the ordinary symbol starting means 20 detects a game ball, the ordinary symbol of the symbol display section is controlled by random number control. It stops after fluctuating for a predetermined time. It should be noted that numeral symbols are also used for ordinary symbols.

The special symbol starting means 14 is operable to convert between a first state (closed state) which is disadvantageous to the player and a second state (open state) which is advantageous to the player, and a pair of left and right openable pawls 26 which can be opened and closed freely. An electric tulip with is used. The special symbol starting means 14 is configured such that the opening / closing claw 26 is opened for a predetermined time when the ordinary symbol after the variation of the ordinary symbol display means 25 stops and displays a predetermined symbol or a combination of predetermined symbols (hit symbol). . Normally, the symbol starting means 20 is constituted by a passage gate or the like. The normal symbol starting means 20 may be of a prize-winning type, such as an openable type or a non-openable type.

The variable winning means 15 is operable to convert between a first state (closed state) which is disadvantageous to the player and a second state (open state) which is advantageous to the player, and can be freely opened and closed around a lower horizontal axis. A special design 22a to 24a which is provided with a pivotally supported opening / closing plate 27 and which is stopped and displayed on each of the symbol display portions 22 to 24 after the change is a special symbol or a combination of specific symbols (big hit symbol)
(For example, "3.3.3", "5.5.5", "7.7.7"
In such a case, the opening / closing plate 27 is opened to the front side to shift to a special game state advantageous to the player.

The variable winning means 15 has a specific area 28 therein.
Is provided, and when a winning ball passes through the specific area 28, a so-called special game state is continued. Note that the variable winning means 15 closes the opening / closing plate 27 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 are moved to a specific area.
28, on the condition that it passes through 28
Opening / closing operation is repeated until this time.

FIG. 3 is a block diagram illustrating a control system. Reference numeral 30 denotes a first random number generating means for generating predetermined random numbers such as a random number for determining a special game state (a random number for determining a jackpot or a miss), a random number for determining a variation pattern, and a random number for determining a stop symbol. 31
Is a special symbol variation control means, provided that the special symbol starting means 14 detects a game ball, randomly selects a random number generated by the first random number generating means 30 in response to a symbol starting request at that time, and displays special symbol displaying means. The symbol displayed on each of the symbol display sections 22 to 24 is changed for a predetermined time, and the symbol is stopped at a stop symbol determined by the symbol random number.

Numeral 32 denotes a special display mode judging means for judging whether or not the special symbols 22a to 24a stopped and displayed on the respective symbol display sections 22 to 24 of the special symbol display means 21 after the change are in the special display mode. It is. The special display mode determination means 32
Is determined by the control signal of the special symbol variation control means 31.

Reference numeral 33 denotes a second random number generating means for generating a random number such as a hit / miss random number. 34 is a normal symbol variation control means, provided that the normal symbol starting means 20 detects a game ball, randomly selects a random number generated by the second random number generating means 33 at that time, and generates a normal symbol of the normal symbol display means 25. Is changed for a predetermined time and stopped.

Each of the symbol variation control means 31, 34 has a corresponding one of the symbol starting means 14, 2 during the variation operation of each of the symbol display means 21, 25.
When 0 detects a game ball, a predetermined number (for example, 4)
A hold storage means (not shown) is provided so as to hold and hold the symbols until the symbol change is completed, and the symbol display means 21 and 25 are caused to change the symbol by the number of times of the hold storage. .

Numeral 35 denotes opening / closing control means.
The normal symbol after the change is a predetermined hit symbol, for example, "7"
This is to open the special symbol starting means 14 for a predetermined time (for example, about 0.5 seconds) on condition that the winning symbol is stopped and displayed.

Numeral 36 denotes a special game state generating means, which generates a special game state advantageous to the player when the special display mode determining means 32 determines the special display mode. This special game state generating means 36 determines whether or not the special display mode determining means 32 is in the special display mode, and displays the special symbols stopped and displayed on each of the symbol display sections 22 to 24 after the special symbol displaying means 21 changes. 22a-24a
However, when a special game state is generated on condition that a special display mode such as "7 / 7.7" is displayed, the opening / closing plate 27 of the variable winning means 15 is opened, and a predetermined time has elapsed after the opening. Alternatively, the opening / closing plate 27 is closed when a predetermined number (for example, 10) of game balls have won, and the opening / closing operation is continued up to a predetermined number of times (for example, 16 times) on condition that the game balls pass through the specific area 28. It is made to let.

The special symbol variation control means 31 is provided by the special symbol variation control means 31 shown in FIG.
As shown in (B) and (B), while the special symbols 22a to 24a of the special symbol display means 21 are changing symbols, each symbol display section
When the three special symbols 22a to 24a stopped and displayed at 22 to 24 are in the reach change state in which the special display mode is followed, the ten kinds of symbols that are variably displayed as the special symbol 24a on the changing symbol display unit 24 are displayed. Among the symbols, a function of reducing other types of symbols (nine types of symbols) other than the type of symbols (one type of symbol) corresponding to the special display mode, and one of the types corresponding to the special display mode.
A function is provided when the type of symbol is enlarged, and a special symbol 24a variably displayed on the symbol display portion 24 that is changing along with the reduction and enlargement functions is reduced and enlarged.

That is, the special symbol change control means 31 uses the random number for determining the change pattern of the first random number
a to 24a symbol variation pattern determining means 37 for determining variation patterns, and each symbol of the special symbol display means 21 in a reach variation pattern or a non-reach variation pattern according to the variation pattern determination result by the symbol variation pattern determination means 37. Symbol variation pattern control means 38 for varying and controlling the special symbols 22a to 24a of the display units 22 to 24, and symbol variation pattern determination means 37
Is determined as the reach variation pattern, the symbol display section 24
And a symbol reduction / expansion control means 39 for reducing / enlarging the changing special symbol 24a displayed on the screen.

The symbol reduction / expansion control means 39 includes one of the special symbols 22a to 24a of the three (plural) symbol display portions 22 to 24.
Other symbol display units except for the special symbol 24a of the individual symbol display units 24
The special symbols 22a, 23a of 22, 23 stop at a predetermined symbol corresponding to the special display mode, and the special symbol 24 of one symbol display section 24.
When "a" is in the fluctuating reach state in which it is fluctuating, "0" to "9" are scrolled and displayed on the endless until the stop point.
As shown in FIG. 6, nine types of symbols displayed as the special symbol 24 a on the symbol display portion 24 are reduced symbols, and one symbol is an enlarged symbol. Has become.

That is, the reduction of the special symbol 24a is performed in the symbol display section.
1 from 0 to 9 variably displayed as a special symbol 24a on 24
Of the 0 types of symbols, nine types of symbols other than the one type corresponding to the special display mode are performed.

For example, when the special symbols 22a and 23a of the left and middle symbol display sections 22 and 23 are in the reach fluctuation state in which "7" is stopped and displayed, all three special symbols 22a to 24a are set to "7". Is a special display mode. For this reason, 0 displayed as a special symbol 24a on the symbol display section 24 is displayed.
"0" to "6""8""9" other than the symbol "7" of the type corresponding to the special display mode among the ten types of symbols "9" to "9"
The nine types of symbols are reduced and displayed.

The size of the reduced symbol at this time is, for example, as shown in FIG.
3 is about half the size of the normal special symbols 22a and 23a that are already stopped and displayed, so that two symbols before and after are displayed on the symbol display unit 24 during scrolling change. is there.

The enlargement of the special symbol 24a is performed for one of the ten types of symbols 0 to 9 displayed as the special symbol 24a on the symbol display section 24, which corresponds to the special display mode. I have.

For example, when the special symbols 22a and 24a of the left and middle symbol display portions 22 and 23 are in the reach fluctuation state in which the "7" is stopped and displayed, the symbol is displayed as the special symbol 24a on the symbol display portion 24. Among the ten types of symbols from 0 to 9, the type "7" of the type corresponding to the special display mode is enlarged and displayed.

The size of the enlarged symbol at this time is, for example, as shown in FIG.
The display area of the symbol display section 24 is enlarged in comparison with the above, and the display area is displayed at a ratio substantially equal to the ratio of the normal symbol to the other two symbol display sections 22 and 23. The size of the symbol display section 24 may be fixed, and only the special symbol 24a may be enlarged.

The special symbol 24a of the symbol display section 24 may be stopped and fixed with the reduced symbol or the enlarged symbol as it is. However, the special symbol 24a returns to the normal symbol size from the reduced symbol or the enlarged symbol and stops. It is settled.

In the above-described ball game machine, when the firing handle 10 of the firing means 9 is operated during a game, the game balls of 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 the game board 4 side along 11.

The game balls fired on the upper side of the game board 4 enter the game area 12 of the game board 4 and then fall along the board surface, or enter the normal prize winning means 16 to 19, etc. It falls downward while passing through the symbol starting means 20. When the game ball normally passes through the symbol starting means 20, the second random number generating means 33
, And the ordinary symbol variation control means 34 varies the ordinary symbol of the ordinary symbol display means 25 by random number control.

Then, when the stop symbol after the change of the ordinary symbol display means 25 becomes a predetermined symbol (hit symbol) such as "7", the open / close control means 35 causes the open / close claw 26 of the special symbol start means 14 to move for a predetermined time. When released, game balls can easily enter the special symbol starting means 14, and a state advantageous to the player is generated.

When a game ball wins the special symbol starting means 14, a random number generated by the first random number generating means 30 is randomly selected at the time of detecting the game ball, and the special symbol variation control means 31 is controlled by the random number control. The special symbols 22a to 24a of the respective symbol display portions 22 to 24 are changed for a predetermined time.

At this time, if the special random number value of the special game state determining random number of the first random number generating means 30 is randomly selected, the special symbol which is stopped and displayed on each of the symbol display sections 22 to 24 after the symbol of the special symbol display means 21 fluctuates. 22a to 24a are, for example, "3.3.
Special display modes such as "3,""5, 5.5, 5" and "7, 7, 7" are displayed, and the special display mode determination means 32 determines the special game state, and the special game state generation means 36 operates to play the game. A special game state advantageous to the player occurs, and the variable winning means 15 is opened to the front side, so that the gaming balls can easily win.

When a predetermined time elapses after the variable winning means 15 is opened or when a predetermined number of game balls are won, the variable winning means 15 is closed. However, if the game ball passes through the specific area 28 while the variable winning means 15 is being opened, the variable winning means 15 is opened again, and the same opening and closing operation is repeated up to 16 times.

Each symbol display section 22 to 24 of the special symbol display means 21
After the special symbols 22a to 24a fluctuate for a predetermined time in a predetermined fluctuation pattern under the control of the special symbol fluctuation control means 31,
Stop while gradually decreasing the fluctuation speed in a predetermined order such as left, middle, and right. And the special symbol of each symbol display part 22-24
22a to 24a switch to another demonstration image or the like after a predetermined time has elapsed after the fluctuation operation is stopped,
Alternatively, the display is alternately switched between the demonstration image and the stop symbol until the start of the next variable operation.

At the time of the symbol variation control of the special symbol display means 21 by the special symbol variation control means 31, the symbol variation pattern determination means 37 of the special symbol variation control means 31 disturbs the random number for variation pattern determination of the first random number generation means 30. Special design from figures
The variation patterns of 22a to 24a are determined, and the symbol variation pattern control unit 38 varies the special symbols 22a to 24a of the symbol display units 22 to 24 with the reach variation pattern or the non-reach variation pattern according to the determination result of the variation pattern. Control.

At this time, when the jackpot random number value of the special game state determining random number of the first random number generating means 30 is randomly selected, the reach variation random number value of the variation pattern determining random number is randomly selected, and the special game state determining random number is selected. Also, when a random number out of the range is randomly selected, the reach variation random number value of the variation pattern determining random number is randomly selected under a certain condition, and the symbol variation pattern determination means 37 determines the reach variation pattern.

When the symbol variation pattern determining means 37 determines that the reach variation pattern has been reached, the special symbols 22a to 24a of the symbol display units 22 to 24 fluctuate for a predetermined time, and then the special symbol 22a of the left symbol display unit 22 first. Is stopped and determined, and then the reach fluctuation state occurs in which the special symbol 23a of the middle symbol display section 23 is stopped and determined. At this time, the special symbol 24a of the right symbol display section 24 fluctuates while performing reduction and enlargement as follows by the reduction and enlargement control of the symbol reduction and enlargement control means 39.

For example, when the special symbols 22a, 23a of the left and middle symbol display portions 22, 23 are stopped at "7", ten types of variable symbols are displayed on the right symbol display portion 24 as the special symbol 24a. Among the symbols, one type of symbol “7” corresponding to the special display mode is enlarged together with the symbol display section 24 as shown in FIG. 5B, and the other symbols “0” to “6” “8” “9” Scrolls in a reduced state as shown in FIG. 5A.

For this reason, the size of the symbol "7" corresponding to the special display mode and the other nine types of symbols can be greatly changed, and the special symbols 22a to 24a having sizes which can be easily identified by the player can be displayed. While being used, the symbol "7" corresponding to the special display mode can be emphasized and displayed in comparison with the other nine types of symbols.

Therefore, it is possible to stimulate and elevate the player's expectation that the special symbols 22a to 24a of the symbol display portions 22 to 24 will be in the special display mode after the fluctuation, and the interest of the player will be remarkably improved. . Moreover, since the symbol "7" corresponding to the special display mode is displayed in a state where the symbol display section 24 itself is enlarged, the symbol "7" can be particularly emphasized in comparison with the other nine types of symbols. The effect of raising the expectation of the elderly is great.

[0049] In addition, 1 is variably displayed as the special symbol 24a.
Of the 0 types of symbols, 9 types of symbols not corresponding to the special display mode are reduced. Therefore, when these 9 types of symbols are scrolled sequentially during scrolling and displayed variably on the symbol display section 24, two symbols before and after that are displayed. Symbol display section 24 with one or more symbols
May be displayed.

For this reason, the fluctuation speed of the nine types of symbols which do not correspond to the special display mode is relatively faster than the fluctuation speed of the symbol "7". It is possible to respond to the psychological state of the player playing the game while feeling frustrated, expecting that the symbol “7” will appear sooner.

Further, the nine kinds of symbols which do not correspond to the special display mode fluctuate at a high speed, and the symbol "7" corresponding to the special display mode appears in an enlarged state on the way. The illusion of stopping at symbol "7" occurs due to the speed difference, and the expectation of the player is further improved.

The special symbol 24a of the symbol display section 24 on the right fluctuates while shrinking and expanding as described above. However, if the random number at the time of random selection of the random number for special game state determination is out of range, the symbol display is performed. The special symbol 24a of the part 24 stops and displays the symbols other than the symbol "7", and finally comes off. If the lottery random number is a jackpot random number, the special symbol 24a of the symbol display section 24
Stops and displays the symbol "7", and the special symbols 22a to 24a of the three symbol display portions 22 to 24 are set to the special display mode, so that the special game state is generated by the special game state generating means 36.

Although the embodiments of the present invention have been described in detail, the present invention is not limited to these embodiments.
Various changes can be made without departing from the spirit of the present invention. For example, in the embodiment, the case where the special symbol display unit 21 includes three symbol display units 22 to 24 is illustrated, but the number of the symbol display units 22 to 24 may be one, or two or three. Four or more may be used. The enlarged symbol may be a plurality of symbols before and after including the symbol corresponding to the special display mode.

The reduction and enlargement of the special symbols 22a to 24a are most effective when the reach is in a state of change when the player's expectation and other mental states are taken into consideration. As long as the special symbols 22a to 24a stopped and displayed on the symbol display units 22 to 24 are in a fluctuating state that follows the special display mode, the same operation can be performed in a state other than the reach fluctuating state.

Each symbol display section 22 to 24 of the special symbol display means 21
May be arranged side by side in the horizontal direction as in the embodiment, or may be arranged vertically and horizontally. Special pattern 24a
When reducing or enlarging a pattern, each type of design may be made similar, or the shape, color, etc., of the same type of design may be changed at the same time as long as it can be identified to be the same type of design. May be changed. The form of reduction and enlargement of the special symbol 24a may be freely determined. When there are a plurality of symbols corresponding to the special display mode, all of them may be enlarged or only the corresponding specific symbols may be enlarged.

In the embodiment, in the ball game machine provided with the ordinary symbol display means 25 and the special symbol display means 21, the special symbols 22a to 24a of the special symbol display means 21 are described as the special game symbols. However, it may be adopted for both the ordinary symbol display means 25 and the special symbol display means 21, or may be adopted only for the ordinary symbol display means 25 side. Further, the ordinary symbol display means 25 can be omitted.

In addition, the present invention can be applied not only to a ball game machine such as a pachinko machine, an arrangement ball machine, a sparrow ball game machine, but also to a spinning type game machine.

[0058]

According to the present invention, the symbol starting means 14, the symbol display means 21 having one or a plurality of symbol display sections 22 to 24 for displaying special game symbols 22a to 24a, and the symbol Symbol variation control means 31, which varies the symbols 22a to 24a for the special game of the symbol display units 22 to 24 for a predetermined time and stops them on condition that there is a symbol start request from the start means 14.
On the condition that the special game symbols 22a to 24a stopped and displayed on the symbol display units 22 to 24 after the change become a predetermined special display mode, a special game state which is advantageous to the player is generated. In the gaming machine provided with the special game state generating means 36, the symbol change control means 31 is designed to stop and display the symbols for the special game 22a to 22b on the symbol display sections 22 to 24.
When 24a is in the fluctuating state following the special display mode, it corresponds to the special display mode among a plurality of types of special game symbols 24a fluctuated and displayed on the symbol display section 24 during the fluctuating state. Since it has a function that can reduce at least a part of other symbols other than the symbols, it corresponds to the special display mode while using the special game symbols 22a to 24a of a size that can be easily identified by the player. There is an advantage that the symbol to be played can be emphasized by both the size and the fluctuation speed, and the expectation of the player can be stimulated and the interest can be increased.

The symbol variation control means 31 is provided in the symbol display section 22.
When the special game symbols 22a to 24a stopped and displayed on the symbols 24 to 24a are in the fluctuating state following the special display mode, a plurality of kinds of special game symbols fluctuated and displayed on the changing symbol display unit 24 are displayed. 24a, at least the function of enlarging the pattern corresponding to the special display mode is provided, so that the difference between the type of the pattern corresponding to the special display mode and the other type of pattern can be further increased, and the player Interest can be further increased.
