Abstract

PROBLEM TO BE SOLVED: To avoid double prize winning without performing symbol arrangement like lowering the relative frequency of a prize winning symbol. SOLUTION: The symbol arrangement on respective reels 8a, 8b and 8c is set so that symbols related to prize winning is arranged on every other frame or continuously. When the establishment of prize winning is determined by lottery after the respective reels 8a, 8b and 8c are activated, the respective first and second reels, to which stop operation is performed, are controlled so as to be stopped in the state of pulling the determined symbol on a prescribed effective line. When the final stop operation is performed and there is the possibility of double prize winning to establish the symbol combination of prize winning on plural lines, the number of frames to be pulled in for the final reel is adjusted and that stop operation is controlled.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention, like a slot machine, moves and displays a plurality of symbol arrays, and then sequentially stops moving display of each symbol array according to a stop operation of a player. The present invention relates to a variable symbol display game machine in which when the moving display of all the symbol columns is stopped, a winning or losing is determined by a combination of symbols formed on a predetermined line in each symbol column.

[0002]

2. Description of the Related Art In a conventional typical slot machine, three rectangular symbol display windows are provided side by side in a row on a front panel on the front side, and a position behind each symbol display window inside the fuselage. And reels each having a plurality of types of symbols on the outer peripheral surface. When a game start operation is performed by the player, the reels rotate at the same time, and the symbol rows on the outer peripheral surface of the reels are displayed in the respective symbol display windows in a moving state.

At the position where the symbol display window is formed, three horizontal lines of upper, middle, and lower, and two oblique lines of lower right and lower left are drawn so as to cover each reel. . When the player performs a stop operation of each reel sequentially in a state where the moving display of the symbol row is performed, the corresponding reel stops, and when all the reels stop, each stop line is displayed. Are displayed in a state where three symbols are arranged for each reel. At this time, if a specific combination of symbols is established on the activated stop line, a winning is achieved, and a privilege such as paying out a predetermined number of medals is given to the player.

More recently, in order to increase the possibility of winning, in addition to the above-mentioned five stop lines,
There has also been proposed a slot machine provided with a mountain-shaped or valley-shaped line that is folded at the position of a central reel (Japanese Utility Model Publication No. 6-5824).

[0005] In this type of slot machine, a combination of a plurality of types of symbols is set in addition to a combination of "7", "7" and "7" indicating a jackpot, as a combination of symbols to be won. For this reason, when all the reels are stopped, there may be a problem that a combination of symbols related to the same kind of winning or a combination of two or more kinds of winning different in value is simultaneously established on a plurality of lines. Therefore, in a conventional slot machine, the arrangement of the symbols on each reel is devised so as not to cause such a double winning, and particularly, the same winning symbols are not continuously arranged.

Further, if the number of stop lines is increased as in the above-mentioned Japanese Utility Model Publication No. 6-58243, it is extremely likely that a plurality of winnings will be established at the same time. Different symbols are arranged.

[0007]

However, if the intervals of the winning symbols are widened in this way, the probability that the winning symbols will be displayed in the symbol display window when the reels are stopped is reduced, and the winning symbols are not displayed. It is difficult to enjoy the original pleasure of a slot machine, in which a stop operation is performed while expecting whether or not it will be established.

The present invention has been made in view of the above-described problems, and it is possible to avoid a double winning without performing a symbol arrangement to lower the appearance rate of a winning symbol, and to stop the symbol row in order. It is an object of the present invention to provide a symbol display that enhances a player's expectation of winning.

[0009]

In order to solve the above problems, according to the present invention, after a plurality of symbol columns are individually moved and displayed, the moving display of each symbol column is performed in response to a stop operation of the player. In the variable symbol display game machine in which symbols are sequentially arranged and displayed on a plurality of lines corresponding to the respective symbol columns, the at least one symbol column is displayed at the time of stop display.
A plurality of symbols related to the winning are set to be simultaneously displayed, and when a final stop operation is performed at the stage where the moving display of each symbol row has been stopped except for one symbol row, the symbol row being moved and displayed. Is stopped to avoid simultaneous establishment of winning symbol combinations on two or more lines.

[0010] Here, "winning symbol combination"
Is not limited to a combination of the same symbols such as “7”, “7”, and “7”, but also a combination in which a plurality of types of symbols are arranged in a predetermined order, such as “7”, “*”, and “*”. Including. In addition, the concept that “winning symbol combinations are simultaneously established on two or more lines” means that not only the same type of symbol combinations are simultaneously established, but also that plural types of winning symbol combinations having different winning values are simultaneously established. Including.

[0011]

By controlling the stop operation of the symbol row to be finally stopped, it is possible to avoid a double winning in which a winning symbol combination appears on a plurality of lines at the same time without arranging winning symbols at intervals. Also at least one
In one symbol row, a plurality of symbols related to winning can be simultaneously displayed at the time of stop display, so as moving display of each symbol row is sequentially stopped, symbols related to winning can be arranged on a plurality of lines. Can be created.

Each of the panels 11, 12, and 13 is formed by performing silk screen printing on the surface of a transparent synthetic resin plate or tempered glass, and the central front panel 11 has a position corresponding to each reel. Non-colored and transparent symbol display windows 20a, 20b, 20c are respectively formed. Further, on the upper panel 12 and the lower panel 13, a model name, game information, and the like are drawn.

A start lever 14 and a stop button switch 1 are provided on a frame portion between the front panel 11 and the lower panel 13.
5a, 15b, 15c, bet button switches 23, 24,
A medal slot 16 and the like are provided, and a medal payout port 17, a medal tray 18, and the like are provided below the lower panel 13.

Each symbol display window 2 of the front panel 11
As shown in FIG. 4, three upper, middle, and lower horizontal lines L1, L2, and L are located at the positions where 0a, 20b, and 20c are formed, so as to cross each symbol display window 20a, 20b, and 20c.
3, and two diagonal lines L descending to the right and rising to the right
4 and L5 are drawn, and these five lines L1 to L
5 independently function as a symbol stop line. Further, in this embodiment, two oblique lines L4,
A valley-shaped stop line L6 and a chevron-shaped stop line L7 that bend at the position of the center reel 8b are set along the line L5. Note that these stop lines L7 and L8 are actually drawn integrally with the stop lines L4 and 5,
In the illustrated example, in order to distinguish each line, the stop lines L7 and L8 are represented by broken lines while being shifted from their original positions.

When the reels are stopped, the symbols of the respective reels 8a, 8b, 8c are arranged on these seven stop lines L1 to L7. Also, inside the front panel 11,
An illumination device 19 composed of a fluorescent lamp is provided. After the power is turned on, the lighting device 19 is always lit, and the respective reels 8a, 8
Illumination is performed on the outer peripheral surfaces of b and 8c from obliquely above.

In this embodiment, the mechanical reel 8
The symbols are moved and displayed by a, 8b and 8c. Instead of the reels 8a, 8b and 8c, the symbols are moved and displayed by using a rotating body such as a belt or a disk. You may. Alternatively, the symbol row may be displayed on a liquid crystal display panel or a display screen of a CRT display by scrolling by displaying the symbol as an image.

The slot machine of this embodiment can execute a so-called credit-type game in which a large number of medals are stored in the body of the machine and the game is executed by consuming the stored medals. 23, 2
When a predetermined number of stored medals are consumed as inserted medals by the operation of No. 4, a game-enabled state is set. Of the bet button switches 23 and 24, the switch 23 arranged on the vertical plane of the frame is
The switch 24 provided on the inclined surface below the front panel 11 is used to insert one medal each time one operation is performed. This is for inserting medals.

When one medal is inserted due to medal insertion from the medal insertion slot 16 or consumption of a stored medal by pressing the bet button switch 21, only the center stop line L1 is activated. Furthermore, if the number of inserted medals is two, the upper, middle, and lower three stop lines L1 to L1
If L3 is three, all seven stop lines L1 to L
7 are respectively activated. The relationship between the inserted medals and the valid lines is not limited to this. For example, the maximum number of inserted medals is four, and five upper, middle, lower, and diagonal stop lines L1 to L5 are activated by three inserted medals. Alternatively, seven stop lines L1 to L7 may be validated by four inserted medals.

In the slot machine having the above-described structure, a predetermined number of stop lines are activated by a medal insertion operation by the player (meaning either the above-described medal insertion or the operation of the bet button switches 23 and 24). When all the reels 8a, 8b, 8c are started simultaneously by operating the start lever 14, a lottery process is performed in the control circuit unit 25 described later, and a winning state in which any symbol is aligned on the activated line is established. Is determined. When it is determined that a winning is achieved, the control circuit unit 25 stops the determined winning symbol on the corresponding reels 8a, 8b, 8c every time the stop button switches 15a, 15b, 15c are operated. The pull-in control is performed to cause the pull-in.

When a symbol combination of "7" or "BAR" is established at a predetermined position, a "big bonus" and a "regular bonus" are provided, respectively, and a transition is made to a "bonus game" in which a large number of medals can be obtained. .

FIG. 5 shows an example of the symbol arrangement on the reels 8a, 8b and 8c. The left and center reels 8a and 8b
Represents only the symbols necessary for explaining the reel stop control (shown in FIGS. 8 to 10) described later, and only the right reel 8c shows the symbol arrangement of all 21 frames. Also in the figure, D _i of the left column is a counter that indicates the arrangement order of each symbol, the control circuit section 25, for the pull-in control and winning determination process, each symbol a counter value and a pair The symbol array cable corresponding to No. 1 is set.

In the slot machine of this embodiment, at least one portion is provided on each of the reels 8a, 8b, 8c.
By arranging the symbols of “7” alternately or continuously, when the two reels stop, a symbol of “7” called “tempai” is displayed on each of the plurality of stop lines. A uniform state can be made to appear. Further, each reel 8a, 8b, 8c has "7",
There is also provided a place where each winning symbol of "BAR" is arranged every other frame or continuously, and when two reels stop, a tempai with a symbol of "7" for a big bonus and a regular bonus In this case, the case where the symbol “BAR” is simultaneously established is obtained.

However, when a tempai occurs on a plurality of lines as described above, depending on the stop position of a reel to be finally stopped (hereinafter, simply referred to as "final reel"), a winning symbol combination is simultaneously displayed on the plurality of lines. May be established and a double winning may be achieved. Therefore, in this embodiment, as described later, by adjusting the number of drawn-in frames with respect to the last reel, a winning symbol combination is established only in one of the temper established lines to avoid a double winning. Like that.

FIG. 6 shows an electrical configuration of the slot machine. In the figure, a control circuit unit 25 is composed of a microcomputer, a CPU 27 as a control main body, a program 28, a ROM 28 storing a symbol arrangement table shown in FIG. 5, a reference table for lottery, and a RAM 29 used for reading and writing data. Including.

The control circuit 25 is connected to the start lever 14, the respective stop button switches 15a, 15 via a bus 26.
b, 15c, bet button switches 23, 24, a medal sensor 30, input units such as the photoelectric sensor 22 for each reel (in the figure, 22a, 22b, 22c for each reel), a medal payout machine 6, and a reel Reel drive unit 31a,
Output units such as 31b and 31c are connected. The medal sensor 30 is provided inside the medal insertion slot 16 and detects insertion of a medal into the machine body. The reel drive units 31a, 31b, 31c are respectively provided with the reels 8a,
By driving the stepping motors 9a, 9b, 9c of 8b, 8c, the reels 8a, 8b, 8c are rotated and stopped.

FIG. 7 is a functional block diagram showing a part of the functions of the CPU 27. FIG. 2 shows only the circuit configuration of the first reel 8a.
A similar configuration is set for each of the right reels 8b and 8c.

In FIG. 7, a medal detection signal from the medal sensor 30 and an operation signal from the bet button switches 23 and 24 are given to an effective line setting unit 32, and are output from the seven stop lines L1 to L7. A line corresponding to the number of inserted medals is set to be valid.

The reel drive unit 31a receives the clock signal, generates a drive pulse P, and supplies the drive pulse P to the stepping motor 9a to drive the reel 8a. A start command and a stop command are given to the reel drive unit 31a from the control unit 33 of the CPU 27.

When the starting lever 14 is operated, the control unit 3
3 receives a start signal, and in response to this, the control unit 33 issues a start command to the reel drive unit 31a to operate the stepping motor 9a. After this, stop button switch 1
When 5a is pressed and a stop operation signal is input to the control unit 33, the control unit 33 issues a stop command to the reel drive unit 31a to stop the operation of the stepping motor 9a.

During this time, the drive pulse P is given to the counting section 34 of the CPU 27 and counted. The count value K by the counting section is reset by a reference signal given from the photoelectric sensor 22a of the reference signal generator 20 every time the reel 8a makes one revolution. This count value K is the current rotation angle position of the reel, in other words, the symbol display window 20.
a to represent a symbol located at a predetermined reference position, and specifically, a counter D having the same value as the count value K.
Indicates that the symbol of _i is located at the reference position.

In this embodiment, the lower symbol stop position in the reel display window 20a, that is, the position of the stop line L3, is set as the reference position. With reference to the symbol arrangement table in the table, which symbol on the reel 8a is located on each line is detected, and the detection result is output to the determination unit 36 and the control unit 33.

The judging section 36 includes the other reels 8b, 8
A symbol detection result is also given from the symbol detection section for c. When all three reels 8a, 8b, 8c have stopped, it is determined whether or not a combination of winning symbols has been established. . The result of the setting by the valid line setting unit 32 is given to the determination unit 36, and the above-described determination processing is performed for all the activated lines.

The lottery section 37 carries out a lottery using random numbers when the start lever 14 is operated and the reels 8a to 8c start rotating, and determines a combination of symbols to be established on the activated line. The control unit 33 controls the stop button switch 15
When a stop operation signal is input from a, based on the detection result by the symbol detection unit 35 at that time, a symbol pull-in control is performed such that the symbol determined by the lottery is stopped as much as possible on the active line. carry out.

This control of pulling in the symbols is performed for all the reels 8a, 8b, 8c, and the range of pulling in the symbols is usually limited to four frames or less. However, in this embodiment, when there is a possibility of a double winning at the time when two reels stop, the pull-in control is performed on the final reel not limited to four frames, thereby avoiding the double winning. .

FIGS. 8 to 10 show various cases in which there is a possibility of double winning and reel stop control. Here,
In each case, each of the reels 8a, 8b, 8c has a left, center,
It is assumed that the stop operation is performed in the right order. Also with indicating the value of the parenthesized numerals of the counter D _i corresponding to the left side of each symbol, for corresponding to the final reel reel 8c, the symbols located before and after in the reel display window 20c, there stands a few frame of . In addition, here, it is assumed that all the seven stop lines L1 to L7 are activated, and among these, only the line in which the winning or the winning is established is shown by the solid line.

First, in the example of FIG. 8, each of the left and center reels 8
a and 8b are stopped with the symbols of the counters (12) to (14) and (19) to (21) displayed in the symbol display windows 20a and 20b, respectively.
Each of the two lines L4 and L6 has a symbol "7". At this time, the last reel 8c
However, if the stop operation is performed at the position shown in FIG. 8A, the symbol “7” of the counter (12) located two frames after the upper symbol stop position is selected as the pull-in control target. .

At this time, when the reel 8c is moved by four frames from the stop operation position to draw the symbol of the counter (12) to the lower symbol stop position, as shown in FIG. Further, the symbol "7" of the counter (14) two frames later is drawn into the upper symbol stop position, and as a result, the symbol combination of "7" is established on both the lines L4 and L6, which are the established lines of the template. Malfunction occurs. In this case, as shown in FIG. 8 (3), the reel 8c is moved by two frames, and the symbol "7" of the counter (12) is used only for the symbol "7" on the line L6. Is established to avoid double winning.

Next, in the example of FIG. 9, each of the left and right reels 8
a and 8b are counters (13) to (15),
Stop while displaying each symbol of (6) to (8),
There is a state in which a template with the symbol of "7" is established on four lines L1, L2, L4, and L6. At this time, assuming that the last reel 8c has been stopped at the position shown in FIG. 9A, the symbol "7" of the counter (21) four frames after the upper symbol stop position at this point is set as the pull-in target. Is selected as

Thereafter, when the reel 8c is moved to four frames, which is the limited number of frames for the pull-in control, and the symbol "7" of the counter (21) is drawn to the upper symbol stop position, the temper is established. A symbol combination of "7" is formed on each of the two lines L2 and L6, and a double winning is generated (FIG. 9 (2)).
Therefore, in this case, by moving the reel 8c by five frames and pulling the symbol "7" of the counter (21) to the symbol stop position in the middle stage, "7" is obtained.
Are limited only to the center line L1 (FIG. 9 (3)).

Next, in the example of FIG. 10, the reels 8a and 8b
Are counters (3) to (5) and (19) to (2
Each symbol of 1) is displayed and stopped. As a result, a symbol “7” is formed on the two lines L4 and L6, respectively, and a “BAR” for a regular bonus is further displayed on the line L3. Has also been established.

In this case, if it is determined by lottery that a symbol combination of "7" for the big bonus is established, "7" of the counter (21) located three frames above the symbol stop position in the upper row is determined. Symbol is selected. In this case, when the reel 8c is moved by three frames, as shown in FIG. 10 (2), the symbol combination of "7" is established only on the line L6 of the tempai established lines. , The symbol “BAR” of the counter (19) is pulled into the lower symbol stop position, and the regular bonus “BA” is displayed on the line L3.
There is a problem that the symbol combination of "R" is established.

Therefore, in this case, by moving the reel 8c by five frames and pulling the symbol "7" of the counter (21) to the lower symbol stop position and stopping it, the symbol combination "BAR" Is established, and a symbol combination of a big bonus is established on the other line L4, which is a line for forming a bonus.

In the reel 8c, the position of the counter (17) two frames before the counter (19) is also set.
Since the symbol "BAR" is provided, if it is determined that the symbol combination "BAR" is established by lottery, the reel 8c is moved to the position shown in FIG. The "BAR" symbol of the counter (17) may be drawn to the lower symbol display position by moving one frame from the stop operation position of 1).

As described above, according to the symbol arrangement shown in FIG. 5, it is possible to generate a possibility of winning on a plurality of lines at the time when each reel stops sequentially. At the time of the final stop operation, the player performs the operation with a strong sense of expectation for winning, and watches the stop operation of the final reel. In fact, when the lottery is "big hit" or "hit", the determined winning symbol combination is established with high frequency,
A high winning reliability can be set without the betrayal of the player's expectation.

However, in the case where a plurality of types of tempais are established, if the retraction control of an extremely large number of frames is executed in order to finally establish a winning only on a single line, the player may feel suspicious. So, pull in the last reel,
It is desirable to keep it within the range of 5 to 6 frames as in the above embodiment. In some cases, in the pull-in of four frames, a stop operation may be performed at a position where a winning symbol combination is not established on any line.
In this embodiment, in such a case, the number of drawn-in frames of the last reel is limited to four frames, and the reel is stopped in a state of "missing".

FIG. 11 shows the flow of control of the slot machine by the control circuit 25. In the figure, “ST” indicates each control step. In ST1, when there is a game start operation by the player, that is, a medal insertion operation and an operation of the start lever 14, the CPU 27 simultaneously rotates all the reels 8a, 8b, 8c and determines whether or not a winning is achieved. A lottery for determination is performed (ST2, ST3).

If the lottery is "losing", the next step ST4 becomes "NO" and the process proceeds to ST17. Thereafter, every time the player performs a stop operation, the CPU 27 controls the corresponding reel by operating the corresponding reel. Stop at the timing according to. However, if the final stop operation is performed at such a timing that the same symbol is established on the activated line, the corresponding reel is moved by a predetermined number of frames, and the winning symbol combination is shifted. Stop display.

On the other hand, if the lottery is "big hit" or "hit", ST4 becomes "YES" and the processing of ST5 to ST16 is performed. First, in ST5, when there is a first stop operation by the player, the process proceeds to ST6, and C
The PU 27 draws the winning symbol determined by the lottery on a predetermined activated line and stops it. In this case, the number of drawn-in frames is limited to four or less.

Hereinafter, the same control as described above is performed also at the time of the second stop operation. When two reels stop, ST7 becomes "YES", and when the final stop operation is performed, ST8 becomes "YES". Becomes In response to this, the CPU 27
Tentatively sets, for the last reel, the number of drawn-in frames necessary to establish a symbol combination according to the lottery result on a predetermined activated line, based on the current count value K by the counting unit 34 (ST9). ). However, when it is not possible to establish the combination of the corresponding symbols by pulling in within four frames, the above-mentioned out-of-state is set so that
An arbitrary number of incoming frames within four frames is set.

Next, the CPU 27 checks whether or not a double winning is generated by drawing in the last reel by the set number of frames (step 10). If the determination is "YES", the process proceeds to ST11, and it is checked whether or not a single winning can be achieved by correcting the temporarily set number of drawn-in frames.

As shown in FIG. 8 described above, a single prize can be achieved by reducing the number of drawn-in frames, or FIGS.
When the number of drawn-in frames is increased to 5 to 6 as described above, when a single prize is possible, ST11 becomes "YES". In response to this, the CPU 27 corrects the number of drawn-in frames to the number of frames that can be awarded independently, and then executes the pull-in control for the final reel, and displays the number on one of the activated lines.
A winning symbol combination based on the lottery result is established (ST12).

When the winning is established in this manner, the CPU
In step ST14, the process proceeds to ST14, in which a display lamp or an audio circuit (not shown) is driven to notify the establishment of the prize, and the medal payout machine 6 is driven to pay out a predetermined number of medals. When the symbol combination of “7” or “BAR” is established, the process proceeds to a bonus game routine (not shown) after this process, and a predetermined number of bonus games are executed.

On the other hand, if even if the number of drawn-in frames is increased to six, the double prize can still be eliminated and a single prize cannot be established,
The process proceeds from ST11 to step 13, and the pull-in control is performed on the last reel so that the winning symbol combination is deviated in all the activated lines.

If it is determined in step ST10 that there is no possibility of a double winning, the process proceeds to step ST15, and the final reel is stopped under the pull-in control for the number of frames set in step ST9. Accordingly, when a winning symbol combination based on the lottery result is established on any of the activated lines, ST16 becomes "YES", and the process proceeds to a winning process of ST14.

In the above embodiment, in order to simplify the explanation, the symbol combination of "7" for the big bonus is
This is limited to the case where the symbol combination of “BAR” for the regular bonus is simultaneously established. However, the same processing is performed when there is a possibility that three or more types of symbols including other general winnings may cause a double winning. Can be implemented. Further, the winning symbol combination is not limited to the combination in which the same type of symbols are arranged as in the above-described embodiment, but may be a combination in which a plurality of types of symbols are arranged in a predetermined order.

Further, the above embodiment is directed to a slot machine in which seven stop lines are set, but the present invention is not limited to this. The present invention can be applied to a model in which an arbitrary number of lines is set.

[0061]

As described above, according to the present invention, at least one symbol display row is set so that a plurality of symbols related to a prize at the time of stop display can be displayed simultaneously, and a symbol row stopped by the final stop operation is provided. In contrast, the stop operation is controlled so that a winning symbol combination is not simultaneously established on two or more lines.
Even if the symbol arrangement is not performed so as to lower the appearance rate of the winning symbols when the moving display is stopped, the double winning can be easily avoided. In addition, as the symbol arrays are sequentially stopped, there is a possibility that winnings will be established on a plurality of lines, thereby greatly increasing the player's expectation.
