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 and a slot machine.

[0002]

2. Description of the Related Art As a kind of gaming machine, a pachinko machine, a slot machine, etc. having variable display means for variably displaying symbols as identification information on three variable display portions and then stopping and displaying a fixed symbol for each variable display portion. It has been known.

In this type of gaming machine, a special game state advantageous to the player is generated on the condition that the combination of the fixed symbols displayed on the active line of the variable display means is a combination of the specific symbols. As an example of the special game state, for example, in a pachinko machine equipped with a special accessory having a special winning opening, there is a state in which the special winning opening is opened to allow a player to acquire a large amount of premium balls, for example, a slot machine. Thus, there is a state where the expected coin payout value increases during the predetermined number of games. The variable display means displays a plurality of rows as the three variable display sections, for example, a symbol row in three rows of left, middle, and right, and a predetermined symbol such as a coincidence of a fixed symbol on a predetermined effective line. In the case of such a combination, the special game state is generally set.

Some conventional gaming machines are provided with a stop switch to stop the symbol being variably displayed. Rather, slot machines are generally provided with a stop switch. In the case where the symbol display means is provided with three symbol rows of left, middle and right as described above, three stop switches are provided corresponding to each symbol row.

When the stop switches are operated in an appropriate order in a state where each symbol row is variably displayed, the symbol rows corresponding to the operated stop switches are sequentially stopped. When each symbol row is attached to the surface of a mechanical reel, only the reel is allowed to slide within a predetermined time after the stop switch is operated, as if the player stopped the game. It seems that the symbol is determined by the operation of. Usually, only a few frames (specifically, four frames) are allowed to slide. Thereby, the player can feel as if he or she has gained a profit state such as a big hit by his or her skill.

A description will be given of how the variable display means is controlled to be displayed by taking a gaming machine provided with the above-mentioned stop switch as an example. A pattern that can be taken for each symbol row when stopping after sliding one frame, stopping after sliding two frames, stopping after sliding three frames, and stopping after sliding four frames Has become. Normally, there are three symbol rows, but unless five patterns of data are prepared for each symbol row, sliding display control cannot be performed on all symbol rows.

When performing this control, the CP which is the control center is used.
Although a U is required, a Z80-CPU or a 68-series CPU is used as a CPU in a gaming machine in consideration of easy inspection, easy fraud detection, and the like. Z80-CPU and 6
The eight-system CPU has eight data input / output pins for data exchange, and reads programs and exchanges data with peripheral circuits in 8-bit units (1 byte units).

In the case where the same type of data is to be provided for each of the three symbol columns, two bits are allocated to each symbol column in consideration of the easiness of creating a data structure, and the lower two bits are assigned. Is a left symbol column, the upper two bits are a middle symbol column, and the upper two bits are a right symbol column, so that each symbol column has four types of data from "00" to "11".

[0009]

However, in the method of allocating two bits to each of the three symbol columns for each symbol column, the most significant two bits become a waste area, and the data capacity is wasted. As a result, a memory having a large storage capacity is required, or a memory having a limited storage capacity causes a problem of insufficient data.

When five or more types of data are required for each symbol row as in the case of the above-described sliding display control, three bits are required for each symbol row. It becomes 9 bits. Then, data for all the symbol columns cannot be stored in one byte. Therefore, as described above, Z80-
In the case of exchanging information in units of one byte as in a CPU, a series of information is not transmitted unless transmission processing is performed twice, which simply requires twice as long. . In addition, there is a case where the data capacity is doubled because the data cannot be stored in one byte. This is a particularly important problem in a game machine such as a pachinko machine or a slot machine having a limited storage capacity. is there.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and it is an object of the present invention to reduce waste of data capacity and reduce the number of times of data transmission by adopting a method instead of a method of distributing data in bit units. One of the main objectives is to provide a gaming machine that can do this.

Can be positioned as a guiding means, a direction adjusting means, or a speed adjusting means of the game ball B in the game area 22 provided in the game area 22. Further, in addition to the above, inside and outside the game area 22 of the pachinko machine 1, various lamps and electric decoration members for enhancing a game effect are attached, and these electric decoration members and the like are changed according to the progress of the game. The lighting state (extinguished, lit, blinking, etc.) can be changed, and can be positioned as the illumination means provided in the pachinko machine 1.

Next, a specific configuration of the display section 41 of the special symbol display device 32 will be described. Display 41
, A symbol row or a 3-digit special symbol row constituting the variable display section is variably displayed. In addition, for convenience of explanation, in the following, the left symbol row, the middle symbol row,
Called the right symbol row. In each symbol column, a plurality of symbols as identification information are variably displayed in a circulating manner. Here, as an example, a description will be given of a case where the types of symbols displayed in each symbol column are configured by arranging ten numbers “0” to “9” in ascending order, and the symbols are variably displayed so as to circulate. However, the symbols need not be limited to numbers, but may be patterns, colors, pictures, etc., as long as they can be distinguished from each other.

Then, when a predetermined combination of symbols is determined on a predetermined active line (various modes such as a five-line configuration and a one-line configuration are possible as the active line) (here, each line is determined). The special game state is generated with the “fixed symbol matches” as a big hit symbol. That is, a case where each of the confirmed symbols coincides with each other on the activated line is defined as a big hit symbol.

As described above, the symbol on the display section 41 is also started to fluctuate on the condition that the game ball B is awarded to the special symbol operating port 31, but it fluctuates at a high speed at the beginning of the fluctuation. When a predetermined time (for example, 30 seconds) elapses after the start of the fluctuation, the symbol stop processing of each symbol row is performed. If the stop switches 15, 16, 17 are operated before that, the operation is stopped. As a result, the symbols in the corresponding symbol row are stopped. In this way, the symbols are stopped, and a fixed symbol is obtained. Each stop switch 1
The operations of 5, 16, and 17 are invalidated until a predetermined time (for example, 1 second), which is significantly shorter than the time (30 seconds) for forcibly performing the symbol stop processing as described above, after the start of the fluctuation. Is done. That is, even if each of the stop switches 15, 16, 17 is operated, for example, 0.5 seconds after the symbol change, no stop processing is performed.

By the way, in a stage before the jackpot symbol is obtained as the confirmed symbol on the display section 41, a reach state is often passed. The reach state includes a special game state that is a big hit state as described above, and also includes a case where the finally determined fixed symbol does not become a big hit symbol and is in an out-of-reach state. In any case, as the reach state, it is preferable to set various reach patterns set so that the expected value at which the big hit state occurs (big hit expected value) is different.

The pachinko machine 1 is provided with various detection switches, sensors, and other detection means for detecting a game state that changes according to the operation of the player. For example, it corresponds to the special symbol operating port switch 71 provided corresponding to the special symbol operating port 31, the V zone switch 72 and the count switch 73 provided corresponding to the special accessory 33, and the normal symbol operating port 34. The switch 74 for the normal symbol operation port provided as such. Special design switch 71
Detects the winning of the game ball B to the special symbol operating port 31, and
The zone switch 72 detects that the game ball B has passed through the V zone for the continuation of the round, and the count switch 73 detects that the game ball B has won the large winning opening 43. In addition, although not shown, detection switches such as limit switches for detecting the operation states of the stop switches 15, 16, and 17, operation detection switches for detecting the operation state of the operation handle 13, and magnetic sensors for preventing fraud are provided. Is provided.

Based on the detection results of the detection means such as the switches 71 to 74, the special accessory 33 (solenoids 45, 4) is used.
7) for controlling the drive of the special symbol display device 32 (display unit 41, hold lamp 42), the normal symbol display device 35 (normal symbol display unit 51 and the hold lamp 52), the normal accessory 36 (wing 53), etc. Is provided with a control device 81. The control device 81 includes the stop switches 15, 1
6 and 17 are also connected, and each stop switch 15, 16, 1
7 are input. That is, the limit switches provided in association with the respective stop switches 15, 16, 17 are turned on when the respective stop switches 15, 16, 17 are pressed and turned off when the pressed switches are released. When the output of the stop signal is stopped (at the time when the pressure is released), the stop switch 15,
The display control resulting from 16 and 17 is executed. Although the control device 81 is schematically shown in FIG. 2, it is actually mounted on the back side of the game board 5.

The control device 81 as control means includes a read-only memory (ROM) as storage means, a central processing unit (main control CPU) as main control means, a random access memory (RAM) as storage means, and the like. Have. The CPU is a Z-80 type, and the transmission and reception of commands and data are performed in eight bits (one byte) by eight data input / output pins. Therefore, data or the like exceeding 1 byte is realized by a plurality of transmission / reception processes. It should be noted that other than the Z-80 system CPU, another type such as a 68 system CPU that transmits and receives data and the like in 1-byte units may be used.

A display control device (display control CPU, ROM, R
AM etc.) are provided on the special symbol display device 32 side, separately from the central processing unit for the main control. That is,
The control device 81 is not actually a single device, but comprises a plurality of control devices. The display control CPU is also of the Z-80 type, but another type of CPU may be used.
The main control and the display control may be realized by the same CPU. In any case, in the present embodiment,
At least the CPU that controls the main control is a Z80 type.
It is assumed to be a simple one that assumes transmission and reception in byte units.

The ROM stores a predetermined control program and initial data in advance. In particular, the pachinko machine 1 is stored in the ROM.
A counter group composed of various counters and an appropriate table group used for the control are stored. The counter group includes a round counter, a hold counter, a winning counter, and the like, an internal random number counter that is updated at predetermined time intervals such as 2 ms intervals, a missed reach random number counter, a jackpot symbol random number counter, a plurality of symbol random number counters, and a reach type. A decision counter and a stop mode decision counter are included. In the table group, various fixed symbols, symbol variation modes, reach modes, stop modes, and the like are stored in advance in a state associated with the counter group.

The round counter is a special accessory 33.
The winning counter is for counting the winning number of the game balls B to the special winning opening 43 based on the detection result of the count switch 73. The hold counter is used to count the number of times the special symbol display device 32 holds the variable display. The internal random number counter is for determining whether or not to generate a big hit state on the display unit 41 of the special symbol display device 32. The out-of-reach random number counter is for determining whether or not to perform display in the out-of-reach state in which the display unit 41 goes through the reach state but does not generate a big hit state. The jackpot symbol random number counter is used to determine a jackpot symbol on the display unit 41. The display unit 41 includes a plurality of symbol random number counters.
Is to determine what the finalized design is,
It is used when determining a departure symbol that does not go through the reach state and a departure reach symbol in the departure reach state. The reach type counter determines the type of reach (effect) performed on the display unit 41. The stop mode determination counter is provided with a stop switch 1 in each symbol row on the display unit 41.
When 5, 16 and 17 are operated effectively (that is, when the symbol is forcibly stopped before a predetermined time elapses)
This is used when determining a stop mode such as slippage of the vehicle. In addition to the above counter group, various counters and the like related to the symbol display device 35 are also prepared.

The main control CPU executes various arithmetic processes in accordance with a control program including the aforementioned counter group and table group in the ROM. In the RAM, the calculation result by the main control CPU, for example, the current round number based on the round counter, the current reserved ball number based on the reserved counter, the number of winning balls to the special winning opening 43 based on the winning counter, Jackpot flag value based on internal random number counter,
The value of the off-reach flag based on the off-reach random number counter, the big hit symbol based on the big hit symbol random number counter when the big hit flag is on, the off-design and the off-reach design based on the plurality of design random number counters, the reach type The reach type based on the determination counter, the fluctuation stop mode based on the stop mode determination counter, and the like are temporarily stored.

The big hit state, the off-reach state, the off-state, the fixed symbol and the reach type in each of the above states related to the display portion 41 are as follows. It is derived from the timing detected by the switch 71 or a predetermined timing correlated with the timing.

When the operating handle 13 is operated by the player, the game balls B on the upper tray 8 are sequentially supplied to the automatic hitting ball supply device provided on the front plate 9, and the game balls B are supplied.
Of the game board 5 along the guide rail 21 by the repulsion operation of the ball launching device including the motor and the ball rod.
Fired at 2. The game ball B guided to the game area 22 falls at random, and wins, for example, the normal symbol operation port 34. This winning is normally detected by the symbol operating switch 74, and the detection result is input to the control device 81. Then, the control device 81 causes the ordinary symbol display section 51 of the ordinary symbol display device 35 to change and display, and thereafter stops the symbol change to display the ordinary fixed symbol. If the display result is the specific symbol “7”, the control device 81 opens the blades 53 of the ordinary accessory 36 in a predetermined manner. Thereby, the winning probability of the game ball B to the special symbol operation port 31 is increased. On the other hand, when the display result of the ordinary symbol display section 51 is other than the specific symbol “7”, the ordinary accessory 36
Although the wings 53 are not opened, the winning probability of the game ball B to the special symbol operating port 31 is possible even in this case, although the winning probability is lower than the open state. In addition, the normal symbol display section 5
When the game ball B wins again in the normal symbol operating port 34 before the symbol 1 is determined, the holding lamps 52 are lit as many as the number of the holdings as the holding state. This lighting state is sequentially turned off as the suspended state is consumed.

When the game ball B falling at random in the game area 22 is won in the specific symbol operating port 31, the winning is detected by the special symbol operating port switch 71, and the detection result is controlled. It is input to the device 81.
Then, based on each of the random number counters, the control device 81 determines whether or not the jackpot is in the big hit state, whether or not the hit reach state is set, if the big hit state is, what is the big hit symbol, and if the hit reach state is, what is the hit reach symbol. If the state is neither the big hit state nor the out-of-reach state, what is the out-of-design? After that, the control device 81 variably displays each symbol row of the display unit 41 in the special symbol display device 32, and thereafter, when a predetermined time has elapsed, or before each of the stop switches 15, 16, 17 is operated. Due to this, the fluctuation of the symbol is stopped and the fixed symbol is displayed.
When the game ball B wins again in the special symbol operating port 31 before the symbol is determined on the display section 41, the holding lamps 42 are lit as many as the number of the holdings as the holding state. This lighting state is sequentially turned off as the suspended state is consumed.

When the determined symbol on the activated line of the display section 41 is a predetermined specific symbol indicating a big hit state, a special game state occurs in the pachinko machine 1. In this special game state, the control device 81 operates the special accessory 33 in a predetermined manner. That is, first, the shutter 44 is opened by controlling the drive of the opening / closing solenoid 45. When at least one game ball B passes through the V zone, the V zone switch 72 detects this and inputs the detection result to the control device 81. Then, the control device 81 drives and controls the tilting solenoid 47 to tilt the seesaw 46 toward the winning zone, and thereafter, the large winning opening 4
All the gaming balls B that have won 3 are led to the winning zone. The open state of the shutter 44 is maintained until the number of the game balls B won to the special winning opening 43 by the count switch 73 reaches a predetermined number (for example, 10) or a predetermined time (for example, 30 seconds) has elapsed since the opening. We are closed afterwards.
When the shutter 44 is closed, the seesaw 46 again
It is tilted back to the zone side. The opening / closing operation of the shutter 44 is one round, and the game ball B during the round is
A similar round is repeated on condition that the vehicle passes through the V zone. On the other hand, when the V-zone switch 72 does not detect that the game ball B has passed through the V-zone, the control is performed so that the special game state ends in the round. Although a plurality of rounds such as 16 rounds are provided, for example, control for ending the special game state in one round may be performed. By digesting such a special game state, the player can acquire many premium balls.

As described above, the control device 81 is actually separated between the main control side and the display control side, and the display control side operates based on commands and data from the main control side. Of course, predetermined data is also stored in the display control side in advance. The main control CPU and the display control CPU are both Z
It is an 80 system (or 68 system), and data and commands are exchanged in units of 8 bits (1 byte). In the present embodiment, the feature is in the data structure related to the symbol, so that point will be described using the example of the control of the slip amount of the symbol.

In the present embodiment, each stop switch 15,
When the symbols in each symbol row are stopped as they are operated after the operation of 16, 17 is operated, when stopped after sliding one frame, when stopped after sliding two frames, and stopped after sliding three frames In this case, five patterns for stopping after sliding four frames are prepared in the RAM as storage means on the main control side as a stopping mode. The slip means, for example, the stop switches 15, 16, 1 at the timing of the symbol "1".
It means that the symbol "1" passes through even if the symbol 7 is operated, and one-frame sliding means that if the stop switches 15, 16, 17 are operated at the timing of the symbol "1" as described above, the symbol "1" is passed. ”Passes and stops at symbol“ 2 ”, the two-frame slide refers to the case where symbols“ 1 ”and“ 2 ”pass and stop at symbol“ 3 ”. Three-frame sliding, four-frame sliding and the like have the same idea.

There are five types of such slip-related data in the left symbol row (no slip, 1 frame slide, 2 frame slide, 3 frame slide, 4 frame slide), 5 types in the middle symbol row, and 5 types in the right symbol row. Kind is required. In this case, if allocation is performed on a bit-by-bit basis as in the prior art, the data cannot be stored in one byte.

In this regard, in this embodiment, since five types of data are required, compressed data is created by assembling each data as a quinary number. That is, the data structure is set to “(data of right symbol column) × 25 + (data of middle symbol column)
× 5 + (data of left symbol column) ”. In this case, since there are five types of data in each symbol row, there are 5 × 5 × 5 = 125 combination patterns as the whole data, but this is within 255 which is the maximum value that can be expressed by 1 byte. . As a result, although there are five types of data for each symbol row, all slip data for all symbol rows can be stored in one byte.

For this reason, the CPU on the main control side reads out from the RAM, or the CPU on the main control side sends the CP from the display control side.
The slip data transmitted to U is 1 stored in 1 byte.
It can be completed only by the first transmission process. In addition, the data capacity is reduced, which is particularly effective in a gaming machine having a limited storage area.

On the other hand, since the slip data in a state of being compressed data is expressed in a so-called quinary number, the meaning of the data cannot be grasped as it is. Therefore, the received data needs to be subjected to a predetermined decompression process by the main control CPU or the display control CPU.

Specifically, the received data is set to “25” (= 5
Suppose that the quotient obtained by dividing by × 5) is the slip data of the right symbol row, and the quotient obtained by dividing the remainder obtained by the division by “5” is the slip data of the middle symbol row. If there is, the remainder can be grasped as slip data of the left symbol row.

Through such processing, the main control CPU or the display control CPU can grasp the slip data of each symbol row as decompressed data.

In the above description, the case where five types of slip data are held for each symbol row has been described. However, the same applies to "((right symbol row data)) in the case of six types of slip data.
× 36 + (data of middle symbol column) × 6 + (data of left symbol column) ”, and the receiving side divides by“ 36 ”and then divides the remainder by“ 6 ”to obtain the same effect. can get. Of course, also in this case, the combination pattern is 6 × 6 × 6 = 216, so that the combination pattern is included in one byte.

Further, the number of types of data does not need to be the same in all the symbol columns. For example, even when the left symbol column has six types, the middle symbol column has eight types, and the right symbol column has four types of data, the data configuration is “(right symbol column data) × 48 + (middle symbol column) Data) × 6 + (data of left symbol column) ”. On the receiving side, the quotient obtained by dividing the received data by "48" is the slip data of the right symbol row, and the remainder obtained by the division is obtained by dividing by "6". It is assumed that the quotient is the slip data of the middle symbol row, and the remainder can be grasped as the slip data of the left symbol row.

As described above, according to the present embodiment, with respect to three symbol columns, even when each symbol column has five or more types of data, all the data of the three symbol columns is stored in one byte. This has the advantage of reducing waste of data capacity and reducing the number of transmissions. Note that the condition within 1 byte is that the value obtained by multiplying the number of data types of each symbol row be 255 or less.

In addition to the embodiment described above, the following embodiment can be adopted.

(A) "When the first condition is satisfied in the game, at least after the end of the special game state and until the second condition is satisfied, the special state in which the player can add value is continued. The gaming machine. "The special state here refers to, for example, a state in which the gaming machine provided with the probability fluctuation mode (probable mode) enters the probable mode. The probability change mode includes: (1) increasing the probability that a specific symbol such as “7” is displayed as a fixed symbol on the ordinary symbol display portion 51 as a fixed symbol, to increase the chances that the ordinary accessory 36 operates, and (2) ) By shortening the fluctuation time until the symbol is determined each time in the ordinary symbol display section 51, the ordinary character 3
(3) increase the probability of winning the game ball B by increasing the total opening time of the normal accessory 36, and (4) change the symbol of the display unit 41 of the special symbol display device 32. (5) The big hit expectation value is higher than that in the normal mode, and the like. The probable change mode usually refers to one provided with at least the above (5), but here, a so-called time reduction mode (time reduction mode) or the like is considered as one of the concepts of the probable change mode, and the above (1)
Any of one or a combination of a plurality of (5) to (5) may be used. Here, as the first condition, for example, a condition that the confirmed symbol on the display unit 41 in the special symbol display device 32 is a predetermined symbol from the big hit symbol is set as a condition, or another display or notification is made. A condition may be set as a condition, or only the occurrence of a special game state may be set as a condition. As the second condition, for example, a condition that the determined symbol on the display unit 41 in the special symbol display device 32 is a predetermined symbol from the big hit symbol is set as a condition, or another display or notification is made. Or the condition that only the next or predetermined number of occurrences of the special game state occur, the condition that the number of fluctuations of the display unit 41 becomes a predetermined number, or that the game ball B enters a predetermined winning opening The condition may be a condition until a prize is won, for example, a condition until a special fixed symbol becomes a predetermined symbol, or a condition until a reach state occurs once or a plurality of times. Of course, the first condition and the second condition may be a combination of a plurality of conditions as described above, or may be other conditions. The entry rate or the continuation rate to the probability change mode may be appropriately set, but in order to emphasize the accidental factor, the random number acquisition randomly enters the probability change mode at a predetermined probability or continues. Preferably. In addition, after entering the certainty change mode, so-called limiter control is performed, so that the game is forcibly returned to the normal mode after a predetermined number of special game states occur, thereby suppressing the gambling for the player. This is a preferred control mode.

(B) "Normal symbol display section 51 or display section 4"
A gaming machine according to 1, wherein a plurality of types of symbol change modes until a fixed symbol is set. In this case, for example, each display part 5
The fluctuation of the symbol at 1, 41 can be simply displayed by switching, the rotation can be displayed around the axis, the display can be switched while zooming the symbol, or the symbol can be collapsed or stretched. It is only necessary to appropriately select a plurality of types from various symbol variation modes such as switching display while deforming, or performing re-variation processing on a symbol that appears to be stopped temporarily.

(C) Counters related to random number acquisition (internal random number counter, out-of-reach random number counter, jackpot symbol random number counter, a plurality of symbol random number counters, reach type determination counter, stop mode determination counter, etc.) may be changed as appropriate. For example, a single random number counter may be used to determine a jackpot state, an out-of-reach state, or the like based on the value.

(D) The present invention may be implemented as a pachinko machine or the like of a type different from the above embodiment. For example, once a big hit, multiple times including it (for example, twice or three times)
Until the jackpot condition occurs, the pachinko machine may be implemented as a pachinko machine (commonly referred to as a twice-rights item or a three-times right item) in which the expected value of the jackpot is increased. Further, the pachinko machine may be implemented as a pachinko machine that enters a special game state on condition that a game ball B is won in a predetermined area after a big hit symbol is displayed. In addition to the pachinko machines, the present invention can also be implemented as various game machines such as arepaches, sparrow balls, slot machines, and the like.

A gaming machine in which a pachinko machine and a slot machine are combined may be used. As a specific example, there is provided a variable display means for variably displaying a symbol row composed of a plurality of symbols and then displaying the symbols in a fixed manner, and not having a handle for launching a game ball. In this case, after throwing in a predetermined amount of game balls based on a predetermined operation (button operation), for example, a symbol change is started due to operation of an operation lever, for example, due to operation of a stop button or predetermined time. The fluctuation of the symbol is stopped by the passage of time,
A jackpot condition advantageous to the player is generated on condition that the fixed symbol at the time of the stop is a so-called jackpot symbol, and a large amount of game balls are paid out to the lower tray.

(E) An embodiment relating to the slot machine will be briefly described with reference to the above (d). In a slot machine, for example, a symbol starts to fluctuate by operating an operation lever as a start operation means in a state where a coin is inserted (conceptually input an investment value) and an effective line is determined, and as a stop operation means The change of the symbol is stopped and operated by operating the stop switch of (1). Therefore, as a basic concept of the slot machine,
For example, "a symbol display means for variably displaying a symbol row composed of a plurality of symbols and then displaying a fixed symbol is provided. And the pattern change starts,
A special game that is advantageous to the player on the condition that the symbol change is stopped due to the operation of the stop operation means (for example, a stop switch) or when a predetermined time elapses, and that the fixed symbol at the time of the stop is a specific symbol. Slot machine provided with a special game state generating means for generating a state.

However, in the slot machine, one game from the change of the symbol to the stop is enabled every time an investment value such as coin insertion is inputted, which is different from the concept of holding until the next time in the pachinko machine. . Therefore, in the case where a predetermined special effect is performed without immediately stopping the symbol change even though the stop switch is operated as described above, the input of the investment value such as inserting the coin is performed. It is preferable to invalidate or prohibit the next preparation operation. This invalidity or prohibition may be released after the symbol change is stopped or confirmed.

(F) “When the number of symbol fluctuations held on the display unit 41 and / or the normal symbol display unit 51 is the maximum number or approaches the maximum number of symbols, the symbol on the display unit 41 and / or the normal symbol display unit 51 is displayed. Shortening the time from the start of the change to the determination (or / and the time from the determination of the symbol to the start of the next symbol change). "
For example, it is less likely that a state that satisfies the symbol change start condition, such as a case where the game ball B wins in the special symbol operating port 31, is invalidated.

(G) “The expected value to which the special game state is given differs according to the variation mode until the fixed symbol on the display section 41 is obtained.” With this configuration, the user is more interested in the symbol variation mode. Is poured, and the thickness increases in the game. As such a game, for example, when the swing of the symbol is performed, control is performed so that the expected big hit value is higher than in other cases, or the fluctuation is performed again. It is conceivable to control so that the big hit expectation value becomes higher in the case of the hit.

(H) When the special game state occurs, the special accessory 3
3 is configured to open the special winning opening 43, but instead or in addition thereto, a value is given to the player by other means such as an interlocking tulip.

(I) The effective line, which is a combination of each symbol row of the display section 41, is not limited to a straight line, and may be a line connecting each symbol in a non-linear manner. And effective pay lines may be mixed.

(J) The display colors of the respective display systems are appropriately switched and controlled in accordance with the difference between the modes (for example, the normal mode and the probable change mode) and the difference between the expected big hits. For example,
For example, when the big hit expectation value is increased, control is performed to switch the design from green to red.
Such color switching has effects such as clearing to the player that the gaming state is different from the normal state, and clearly indicating to the player that the expected big hit value has increased.
The technical ideas derived from this are "switching the symbol display color according to the game state.", "Switching the symbol display color according to the mode.", And "changing the symbol display color to the big hit expected value." Display according to the difference. "
and so on.

(K) When the special effects such as the swinging and re-fluctuation of the symbols on the display section 41 are continuously displayed a predetermined number of times, the display itself indicates that the expected big hit value has increased. To keep. The technical idea derived from this is that “when the symbol stop mode on the display unit 41 is performed with a predetermined regularity, the regular stop mode increases the expected value of the special game state. Have a correlation. "

(L) As a special effect on the display unit 41, any effect other than swinging and re-fluctuation can be considered. For example, in the stage before the reach state or the special game state, the symbols that are changing are stopped by the stop switches 15, 16,
Display such that a frame advance operation is performed due to the operation of 17, a change speed of a symbol, or a change direction of a symbol is reversed. Of course, these are only examples.

(M) As a special effect on the display unit 41, a case related to a special game state, such as whether a reach symbol is obtained on an active line and whether a big hit symbol is obtained, has been exemplified. Special effects such as those described above are also possible for those in which the profit state given to the player is lower than the special game state called a so-called small hit, single bonus, regular bonus, or the like. As a concept including a state that is advantageous to the player other than the special game state such as the big hit state, the concept of “when the symbol is determined, the profit status that can be given to the player differs depending on the type of the symbol. A gaming machine having a plurality of advantageous states ". In this case, it is possible to set the appearance rate of the special effect to be different or to set the effect content to be different depending on the difference in the advantageous state.

(N) As an example of the data structure to be stored in one byte, symbol slip data has been described. However, other data structures such as a predetermined reach effect and a notice effect may be implemented. Further, when there are a plurality of types of active lines (for example, five lines) as seen in a slot machine in particular, the data in terms of which line is controlled to stop the symbol is compressed in the above embodiment. The data may be prepared as data. In this case, it is very effective for a slot machine in which a large number of lines such as seven lines are set.

[0095]

As described above, according to the present invention, a gaming machine which can reduce waste of data capacity and reduce the number of times of data transmission by employing a method which is an alternative to the method of distributing data in bit units. The excellent effect that can be obtained.
