Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a game system in which a plurality of symbol arrays are individually moved and displayed by a game start operation by a player, and the movement display of each symbol array is stopped by a player's stop operation. And a variable symbol display amusement machine such as a slot machine for displaying any symbol at each symbol row in a symbol row.

[0002]

2. Description of the Related Art A conventional typical slot machine is provided with three reels each having a symbol array composed of a predetermined number of symbols on an outer peripheral surface. When the player performs a game start operation, the reels rotate at the same time, and a symbol row of each reel is displayed in a symbol display window on the front surface in a state of being moved. When the player performs a stop operation, the reels are sequentially stopped, and symbols for three frames are displayed on the symbol display window in a stopped state.

When a predetermined combination of symbols is established on an activated stop line (hereinafter, referred to as an "effective line") when all reels are stopped, a winning is achieved and a predetermined number of medals are paid out to the player. When a combination of specific symbols (hereinafter, referred to as “special winning symbols”) is established, a special winning is achieved, and the game shifts to a special game called “bonus game” in which a large number of medals can be obtained.

In a conventional slot machine, a lottery process is performed inside the machine for each game, and when a "big hit" occurs in the lottery process, a stop operation of each reel is performed so that the special winning symbol stops on an active line. Is controlled.

In a recent slot machine, if a "big hit" occurs due to a lottery process, even if a special winning symbol combination is not established, a specific symbol or a specific symbol combination called a "reach eye" is established. (Hereinafter simply referred to as "reach eyes"),
Stop control of each reel is performed. When the reach eyes appear, the player knows that the special winning symbols are likely to be aligned on the activated line, and will carefully perform the stop operation in the subsequent games.

[0006] A large number of patterns are prepared as the reach eyes, and at the playground, a reach eye table showing all the reach patterns in the form of a list is displayed for each model. .

[0007]

In order to immediately recognize the appearance of the reach eyes, it is necessary for the player to memorize all the patterns of the reach eyes. It is not easy to memorize all patterns, and it is practically impossible for beginners to recognize the appearance of the reach eyes without fail. Further, it is possible to play the game while checking it with the reach eye table. However, in this case, the player cannot concentrate on the game, which hinders the rapid progress of the game.

The present invention has been made in view of the above-mentioned problem, and enables a player to easily display the reach eyes without memorizing all reach eye patterns or referring to the reach eye table. An object of the present invention is to provide a variable symbol display game machine that can be recognized.

[0009]

According to the present invention, a plurality of symbol rows are individually moved and displayed by a game start operation by a player, and the movement display of each symbol row is stopped by a player's stop operation. In a symbol variable display amusement machine that displays any symbol for each symbol row at a predetermined position, at least one symbol row is specified in order to notify a player that a specific winning may occur. A control device for controlling the stop of the moving display of the symbol row, so that the symbol stops at a predetermined position. The notification control for notifying the player of the stop position of the specific symbol is executed.

[0010] In the invention according to the second aspect, the control device executes the notification control while at least one symbol row is performing moving display from the start of moving display of all symbol rows. ing.

[0011] In the invention according to claim 3, the control device executes the notification control after all the symbol arrays stop moving and displaying.

In the invention according to claim 4, the control device determines the number of stop positions of a specific symbol by a lottery process.

In the invention of claim 5, the control device determines whether or not to execute the notification control by a lottery process.

[0014]

When there is a possibility that a specific winning will occur, the control device controls the stop of the moving display of the symbol array so that the specific symbol of at least one symbol array stops at a predetermined position. The stop position of the specific symbol is notified to the player. When the movement of each symbol row is stopped and a specific symbol stops at the informed stop position, the player knows that a specific prize may occur.

[0015] In the symbol variable display game machine according to the second aspect,
At least 1 from the start of moving display of all symbol columns
The notification control is executed while the individual symbol rows are moving and displayed, so that the player can know in advance the stop position of the specific symbol.

According to a third aspect of the present invention, there is provided a symbol variable display game machine.
Since the notification control is executed after all the symbol columns have stopped moving and displaying, the player can surely recognize when a specific symbol has stopped at a predetermined stop position.

In the symbol variable display amusement machine according to claim 4,
Since the number of stop positions of the specific symbol is determined by the lottery process, the possibility that the specific symbol stops at the predetermined stop position changes according to the number.

In the symbol variable display game machine according to claim 5,
When the lottery is won, a control for notifying the player of the stop position of the specific symbol is executed.

The above-mentioned lottery process is performed by sampling a random number generated by a random number generator and determining whether or not the sampled random number value is a value within a predetermined range. The lottery process is known, and a detailed description thereof will be omitted here.

When all the reels 8a, 8b, 8c are stopped and a special winning symbol or a combination of winning symbols is established on the activated line, a predetermined number of medals are paid out and the combination of special winning symbols is established. Shifts to a "bonus game" in which a large number of medals can be obtained.

In this slot machine, when a "big hit" occurs in the lottery process, the player is notified that special winning symbols are likely to be aligned on the activated line. Stop control of each reel 8a, 8b, 8c is performed so that a reach pattern appears, and a stop position of a specific symbol (in this embodiment, a special winning symbol "7") constituting the reach pattern is played. To the public.

FIG. 4 shows a specific example of the reach eye pattern. The special winning symbol "7" is located at the upper position of the symbol display window 20a on the first reel 8a. The symbol display window 20 is provided on each of the reels 8b and 8c.
b and 20c appear at lower positions, respectively, and form a reach eye pattern. When the reach eye pattern appears, the player recognizes that the special winning symbols are likely to be aligned on the activated line, that is, that a "big hit" has occurred in the lottery process.

There are many types of reach patterns other than the example specifically shown in FIG. Since it is not easy to store all the reach patterns, in this embodiment, the stop position of the special winning symbol “7” constituting the reach pattern is determined by the symbol display windows 20 a and 20.
The player is notified by illuminating any of the rectangular frame-shaped light-emitting portions 41 to 43 formed on b and 20c.
This notification operation is performed when all the reels 8a, 8b, and 8c start rotating, but if the notification is performed in advance, if the notification is performed while at least one reel is rotating.

including.

FIG. 15 shows the flow of control of the slot machine by the control device 50. In the drawing, ST indicates each step of the control. In ST1 of the figure, 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 51 determines whether or not the hit flag is on (ST2). In this case, since the determination is “NO”, the CPU 51 performs a lottery process as to whether or not to execute a pull-in control for drawing a specific symbol on an active line (ST3). As a result of the lottery,
If "big hit", the determination in ST4 is "YES"
And the hit flag is turned on (ST5).

Next, the CPU 51 performs a lottery process for notification in ST6 to determine whether or not to notify the stop position of a specific symbol constituting the pattern of the reach eye, and if so, the stop position. 6 shown in FIG.
It is determined which notification pattern among the types of notification patterns is used.

When the lottery result of notifying the stop position is obtained by the lottery process in ST6, the determination in ST7 is "YES", and the CPU 51 turns on the notification flag in ST8 and sets the three reels 8a. , 8b, and 8c are rotated at the same time, and then the first light source 38 at the corresponding position is turned on based on the determined notification pattern (ST9).
For example, in the notification pattern of FIG. 10, the left side of the symbol display window 20a emits light in the upper position light emitting unit 43, and the center and right side of the symbol display windows 20b and 20c emits light in the lower position light emitting unit 41 in green. Let it.

In the next ST11, all the reels 8a, 8a
It is determined whether or not b and 8c have stopped, and in the next ST12, it is determined whether or not a combination of special winning symbols has been established. If the special winning symbol combination has not been established, it is determined whether or not a specific symbol (in this embodiment, the special winning symbol “7”) has stopped at each of the light-emitting designated positions (S).
T13). If the specific symbol does not stop at all designated positions, the determination in ST13 is "NO",
It returns to ST1 as it is. If the specific symbol stops at all designated positions, the determination in ST13 is “YES”
The CPU 51 turns off the notification flag in ST14,
After turning on the notification end flag, the process returns to ST1.

In this embodiment, the stop operation of each reel 8a, 8b, 8c is controlled so that a specific symbol stops at each designated position. The first to third notification patterns shown in FIGS. Is 1.5 times less likely, and Figure 1
With respect to the fourth notification pattern shown in FIG. 3, the stop operation of each of the reels 8a, 8b, 8c is controlled so that a specific symbol stops at each specified position with a probability of 100%.

If the determination in ST12 is "YES",
For example, as shown in FIG. 16, when a specific symbol does not stop at any of the designated positions displayed by light emission by the issuing units 43 and 42 and the specific symbols are aligned on the activated line and a special prize is won. After turning off the hit flag and the notification flag, the process proceeds to the bonus game (ST15, 1).
6).

In the lottery process of ST3, when the lottery result of “big hit” is not obtained, the CP
U51 performs a lottery process on the notification in ST20, and determines whether to notify the stop position of a specific symbol constituting the pattern of the reach eye, and if so, which notification pattern to use.

If a lottery result of notifying the stop position is obtained, the determination in ST21 is "YES", and the CPU 51 rotates all the reels 8a, 8b, 8c all at once, and the determination is made. Light emission is displayed based on the notification pattern (ST22, ST23), and then the process proceeds to the departure process of ST24. If a lottery result indicating that the stop position is not notified is obtained, the determination in ST21 is “NO”, and the CPU 51 determines in ST25 that all the reels 8a, 8
After rotating b and 8c all at once, the process proceeds to the disengagement process of ST24.

Next, when the player performs a game start operation for the next game, the process proceeds from ST1 to ST2 and the CP
U51 determines whether or not the hit flag is on. If a special prize is not obtained even though the hit flag was turned on in the previous game, the determination in ST2 is "YES", and in ST26 and ST27, whether the notification end flag or the notification flag is on. Is determined.

If a specific symbol is stopped at each of the designated positions illuminated and displayed in the previous game, S
Since the notification end flag is on at T14, ST
The determination at 26 is "YES", and the game proceeds without notification (ST17).

If the specific symbol does not stop at any of the designated positions displayed by light emission in the previous game, ST14 is skipped. As a result, the notification end flag is off, and the notification flag is Since it remains ON, the determination in ST26 is “NO”, and the determination in subsequent ST27 is “YES”. In this case, the CPU 51 again performs the lottery process (ST
After executing (28), a notification is made and the game proceeds (ST9).

In the previous game, the lottery result was "big hit" in the lottery process in ST3, but in the lottery process in ST6, a lottery result indicating that no notification was obtained was obtained, and a special prize was obtained as a result of the game. If not, both the notification end flag and the notification flag are off.
The determinations of 7 are both "NO", and the process proceeds to ST6 to perform a lottery process related to the notification.

In the above embodiment, the notification pattern is fixed during one game. However, the notification pattern can be changed during the game in order to make the game surprising. FIG. 17 shows a light emitting unit 43 in the upper position for the left symbol display window 20a, a light emitting unit 41 in the lower position for the central symbol display window 20b, and an upper position and a central position for the right symbol display window 20c. Each of the light emitting units 43 and 42 indicates a notification pattern to be displayed by light emission. In this notification state, the first reel 8a stops, and the specific symbol does not stop at the upper position of the symbol display window 20a. On the other hand, when the specific symbol stops at the center position, the light emitting unit 43 at the upper position. Is turned off, and the light-emitting unit 42 at the center position is turned on, thereby changing the designated position for light-emitting display.

Whether the notification pattern is changed as illustrated in FIG. 17 is determined by the lottery (ST
6). When performing the change control of the notification pattern, the control flow after ST9 in FIG.
It looks like 8.

In FIG. 18, all the reels 8 are set in ST1.
After rotation of a, 8b, and 8c and light emission display based on the notification pattern are performed in ST2, the CPU 51 determines in step ST3 whether any of the stop button switches 15a, 15b, and 15c has been pressed. When the first stop button switch is pressed, the determination in ST3 becomes “YES”, and then C
In step ST4, the PU 51 determines whether or not the specific symbol has stopped at the designated position of the corresponding symbol display window. When the determination is "NO", if the designated position is to be changed, the process proceeds from ST5 to ST6, where the designated position is changed.

When the second stop button switch is pressed, S
The determination at T7 is "YES", and the CPU 51 determines whether or not the specific symbol has stopped at the designated position of the corresponding symbol display window (ST8). When the determination is “NO”, if the designated position is to be changed, ST
From 9 to ST10, the designated position is changed.

When the last stop button switch is pressed, ST
The determination at 11 is “YES”, and the CPU 51 determines whether or not the specific symbol has stopped at the designated position of the corresponding symbol display window (ST12). The determination is "NO"
, If the designated position is to be changed, S
The process proceeds from T13 to ST14, and the designated position is changed. Thus, in ST15, it is determined whether or not the specific symbol has stopped at all the designated positions.
If "S", the process proceeds to ST14 in FIG. 15, and if "NO", the process proceeds to ST1 in FIG.

In the above-described embodiment, the notification pattern is formed by a combination of three specific symbols. However, the present invention is not limited to this. One specific symbol or two specific symbols are used. The notification pattern may be configured by the combination.

As shown in FIG. 19, two types of specific symbols, green (indicated by a solid line in the figure) and red (indicated by a broken line in the figure), are prepared. 43
Are also green (indicated by a solid line in the figure) and red (in the figure,
Shown by broken lines. ) Are set, and the green light emitting portion 41,
When a specific green symbol is stopped at 43 and a specific red symbol is stopped at the red light emitting portion 42, the specific symbol may be stopped at the specified position.

The light-emitting portions 41, 42, 43 are not limited to those of the above-described embodiment. For example, as shown in FIG. 20, each of the symbol display windows 20a, 20b, 20c has an upper position, a center position, and a lower position. Corresponding to each reel 8a, 8b, 8
c, the lamps 60 may be arranged inside each of them, and as shown in FIG.
The lamps 61 may be arranged on the front panel 11 so as to correspond to the upper position, the center position, and the lower position of a, 20b, and 20c.
