Abstract

<P>PROBLEM TO BE SOLVED: To provide a game machine having an increased irregularity of random number values used for a game. <P>SOLUTION: When detecting rising of a clock signal output from an oscillation circuit 101h, a 16-bit random number updating circuit 101s shifts 16-bit data in a shift register by 1, and calculates exclusive disjunction from data of most significant bits, and feeds back the exclusive disjunction data to least significant bits. When detecting rising of a detection signal from a starting port detecting switch 9a or 10a, a latch register 101t latches 16-bit data generated by a shift register. Jackpot determining processing uses data processed by subtracting 1 from low-order byte 8-bit data of the latched 16-bit data, as a random number value for determining a special symbol. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

  The present invention relates to a gaming machine including a random number generation circuit that generates a random number.

  In a conventional gaming machine, when a game ball wins at a start opening provided on the game board, a random value is acquired at the time of winning, and it is determined whether or not the acquired random value is a preset jackpot random value. However, when it is a jackpot random value, it is configured to control a special game (bonus) that is advantageous to the player.

  Here, for the generation of the random number value, software is used to update the random number counter by adding 1 for each predetermined interrupt (every timer interrupt) by a program (see Patent Document 1), or a clock signal from the oscillation circuit. There is known a hardware-based one that updates the counter of the counter circuit by adding 1 for each input (see Patent Document 2).

JP 2003-93660 A JP 2005-13764 A

However, whether software random number generation or hardware random number generation is used, the random number value is simply incremented (or subtracted) one by one and updated. There was a problem that the numerical value could be easily estimated.
In particular, if the random value used in the game is a random value related to the jackpot, a fraudulent act such as directly aiming at the jackpot random number value etc. is performed by a sensor, etc., and the fairness of the game cannot be secured. It was.

  An object of the present invention is to provide a gaming machine that can increase irregularity of random numbers used in games.

  In the first aspect of the present invention, a clock oscillation circuit (oscillation circuit 101h) that oscillates a reference clock having a predetermined period and a plurality of bit storage units (flip-flops) that store 1-bit information are connected in series. Each time a predetermined number of reference clocks oscillated by the clock oscillation circuit are input, the information stored in the predetermined bit storage unit is transferred to the bit storage unit connected to the succeeding bit storage unit. When a random number update circuit (16-bit random number circuit 101 s constituting a shift register) that stores data after shifting and a predetermined read signal are input, information stored in the bit storage unit of the random number update circuit is used as a random value. Random number storage circuit (latch register 101t) for storing and the random number value stored in the random number storage circuit are fetched, and 1 is subtracted from the fetched random number value and processed. Numerical value processing means (main CPU 101a) and special determination means (main CPU 101a) for determining whether or not the random number value processed by the random number value processing is a special random value, the random number update circuit Performs a predetermined operation (exclusive OR) on the information stored in the first bit storage unit and the information stored in the second bit storage unit, and stores information on the operation result in the third bit storage. And a feedback control unit stored in the unit.

According to the first aspect of the present invention, since information on a predetermined calculation result is fed back to the random number update circuit, the random number value is not updated by +1, but the discrete value is updated and used for the game. The irregularity of random values to be generated can be increased.
Here, in the random number update circuit, when the information of the predetermined calculation result is fed back, the minimum value of the random number update circuit must be set to “1”. This is because, if “0” is stored in all the bit storage units, when “0” and “0” are calculated, the predetermined calculation result is forever the same value (for example, “0”). This is because only the same value is continuously updated. Further, when the minimum value of the random number update circuit is set to “1”, the random number range becomes 1 to 2n−1, and the storage area corresponding to the random value “0” in the data storage area related to the random number determination process is an unused data area. As a result, the storage area is wasted. However, according to the first aspect of the present invention, after performing the process of subtracting “1” from the acquired random number value, it is determined whether or not the processed random number value is a special random number value. Therefore, data can be stored in the storage area corresponding to the random value “0”, and waste of the storage area can be eliminated.

  According to the present invention, it is possible to increase irregularity of random values used in games.

Here, the rotational speed of the firing solenoid 4a is set to about 99.9 (times / minute) based on the frequency based on the output period of the crystal oscillator provided on the firing control board 106. As a result, the number of games played per minute is about 99.9 (pieces / minute) because one shot is fired every time the firing solenoid rotates. That is, the game ball is fired about every 0.6 seconds.

  The lamp control board 104 controls lighting of the effect lighting device 16 provided on the game board 2 and controls driving of the motor for changing the light irradiation direction. In addition, energization control is performed on a drive source such as a solenoid or a motor for operating the production actors 14 and 15. The lamp control board 104 is connected to the effect control board 102, and performs the above-described controls based on data transmitted from the effect control board 102.

  The image control board 105 includes an image CPU, an image ROM, an image RAM, and a VRAM (not shown) for performing image display control of the liquid crystal display device 13, and an audio CPU, an audio ROM, and an audio RAM. The image control board 105 is connected to the effect control board 102 so as to be capable of bidirectional communication, and the liquid crystal display device 13 and the audio output device 18 are connected to the output side thereof.

The image ROM stores a large number of image data such as effect symbols 30 and backgrounds displayed on the liquid crystal display device 13, and the image CPU reads a predetermined program based on a command transmitted from the effect control board 102. At the same time, predetermined image data is read from the image ROM to the VRAM, and display control in the liquid crystal display device 13 is performed. The image CPU executes various image processing such as background image display processing, effect symbol display processing, and character image display processing on the liquid crystal display device 13, but the background image, effect symbol image, and character image are displayed on the liquid crystal display. The image is superimposed on the display screen of the device 13.
That is, the effect design image and the character image are displayed so as to be seen in front of the background image. At this time, if the background image and the design image overlap at the same position, the design image is preferentially stored in the VRAM by referring to the Z value of the Z buffer of each image data by a known hidden surface removal method such as the Z buffer method. .

  The audio ROM stores a large amount of audio data output from the audio output device 18, and the audio CPU reads out a predetermined program based on a command transmitted from the effect control board 102 and Audio output control in the output device 18 is performed.

(Random number generation circuit of one-chip microcomputer 101m)
Next, the random number generation circuit 101r provided in the one-chip microcomputer 101m will be described with reference to FIG.

The 16-bit random number update circuit 101s forms a 16-bit shift register by connecting 16 flip-flops in series. When the rising edge of the clock signal output from the oscillation circuit 101h is detected, the 16-bit random number update circuit 101s The 16-bit data in the shift register is shifted bit by bit.
The detailed configuration of the shift register of this embodiment will be described later with reference to FIG.

  When the control register 101p detects the start of the start port signal from the first start port detection switch 9a or the second start port detection switch 10a and detects the rise of the random number fetch signal from the main CPU 101a, the control register 101p latches the latch signal. Output to the register 101t.

The latch register 101t is a 16-bit register composed of 16 flip-flops. When the rising edge of the latch signal is detected from the control register 101p, the 16-bit data generated by the 16-bit random number update circuit 101s is latched. (Hold. As a result, a random value is generated by the 16-bit random number update circuit 101s, and the random value generated when the game ball is won at the start opening is stored in the latch register. Note that the latch register 101t is configured to latch all 16-bit data generated by the 16-bit random number update circuit 101s when detecting the rising edge of the latch signal from the control register 101p. However, the latch register 101t has 8 bits (bit0 to bit7). ) May be latched only.
In the present embodiment, only one latch register 101t is mounted in the random number generation circuit 101r, but a plurality of latch registers 101t may be mounted.

  The data (random number values) stored in the latch register is divided into a plurality of types of random number values and will be described later in detail with reference to FIG.

(Description of shift register constituting random number update circuit)
Next, a shift register constituting a 16-bit random number update circuit will be described with reference to FIG. In this embodiment, a 16-bit shift register is configured by connecting 16 flip-flops as a 16-bit random number update circuit. However, in order to simplify the description, a 4-bit random number update circuit is used. An example of a 4-bit shift register in which four flip-flops are connected will be described.

FIG. 5A shows an initial state of the 4-bit random number update circuit. Here, in the random number update circuit of the present embodiment, “1” is set as “bit0” as the initial value, and at this time, “1” (0001 as the binary number) is output as the random value.
Here, the initial value of the random number value is set to “1” instead of “0”. In the random number update circuit according to the present embodiment, the higher-order bit “ Since the data of the exclusive OR of “bit2” and “bit3” is fed back to the least significant bit “bit0”, if all the bits are “0” (the initial value is “0”) This is because all bits continue to be shifted forever with “0”, and a new random value cannot be generated.

FIG. 5B is a diagram showing a state where data input to the flip-flop is shifted to the next flip-flop when the clock signal (CLK) is input from the state of FIG. Specifically, the data of “bit 0” is shifted to “bit 1”, the data of “bit 1” is shifted to “bit 2”, and the data of “bit 2” is shifted to “bit 3”. Further, the exclusive OR data of “bit2” and “bit3” is shifted to “bit0” so that the random value counts the discrete values.
Here, data “1” of “bit 0” is shifted to “bit 1”, data “0” of “bit 1” is shifted to “bit 2”, and data “0” of “bit 2” is shifted to “bit 3”. The Further, the data “0” of the exclusive OR of the data “0” of “bit2” and the data “0” of “bit3” is shifted to “bit0”. As a result, “2” (0010 as a binary number) is output as a random value.

FIG. 5C is a diagram illustrating a state where data input to the flip-flop is shifted to the next flip-flop when the clock signal (CLK) is input from the state of FIG. 5B.
Here, data “0” of “bit 0” is shifted to “bit 1”, data “1” of “bit 1” is shifted to “bit 2”, and data “0” of “bit 2” is shifted to “bit 3”. The Further, the data “0” of the exclusive OR of the data “0” of “bit2” and the data “0” of “bit3” is shifted to “bit0”. As a result, “4” (binary number 0100) is output as the random number value.

FIG. 5D is a diagram showing a state where data input to the flip-flop is shifted to the next flip-flop when the clock signal (CLK) is input from the state of FIG. 5C.
Here, data “0” of “bit 0” is shifted to “bit 1”, data “0” of “bit 1” is shifted to “bit 2”, and data “1” of “bit 2” is shifted to “bit 3”. The Further, the data “1” of the exclusive OR of the data “1” of “bit2” and the data “0” of “bit3” is shifted to “bit0”. As a result, “9” (1001 as a binary number) is output as a random value.

  Similarly, when the data is shifted every time the clock signal (CLK) is input, as shown in FIG. 5E, the output random values are “1”, “2”, “4”, “9”, “3”, “6”, “13”, “10”, “5”, “11”, “7”, “15”, “14”, “12”, “8”,. The random values are updated in the range of “1 to 15” without overlapping. In such a random number update circuit, the random number range is updated in the range of “1” to “2n−1” (n is the number of bits) excluding “0”.

  In this embodiment, the exclusive OR of the upper bit “bit2” data and the “bit3” data is fed back to “bit0”. However, the upper bit “bit1” data and Data of the exclusive OR with the data of “bit2” may be fed back to “bit0”, and the combination of data fed back is freely designable. Further, the random number generation circuit includes a one-round detection circuit that detects that the random number value has made one round, and when the round-trip detection circuit detects that the random number value has made one round, the combination of data to be fed back is variable. By providing such a circuit, randomness generation can be made more irregular.

(Latch register data structure)
Next, the data configuration of the latch register will be described with reference to FIG.

  The latch register is a 16-bit shift register formed by connecting 16 flip-flops. The latch register is divided into a lower byte (bits 0 to 7) and an upper byte (bits 8 to 15). Numerical values are used as two types of random values.

  Specifically, the lower byte (bits 0 to 7) is used as a special symbol determination random number value used for jackpot determination, and the upper byte (bits 8 to 15) is used as a random number value for variation pattern for production. .

  In this way, by using one random number value as a plurality of types of random number values, the load for updating the random value used in the game is reduced.

  Next, details of various tables stored in the main ROM 101b will be described with reference to FIGS.

FIG. 7A and FIG. 7B are diagrams showing a big hit determination table that is referred to when determining whether or not a special symbol variation stop result is a big hit. FIG. 7A is a jackpot determination table referred to in the first special symbol display device 19, and FIG. 7B is a jackpot determination table referred to in the second special symbol display device 20. In the tables of FIG. 7A and FIG. 7B, the big hit probability is the same although the winning probability for the small hit is different.
Specifically, the jackpot determination table is composed of a low-probability random number determination table and a high-probability random number determination table, and refers to the gaming state, and the low-probability random-number determination table or the high-probability random-number determination table is selected. Based on the selected table and the extracted random number value for determining the special symbol, it is determined whether it is “big hit”, “small hit” or “lost”.
For example, according to the low probability random number determination table in the first special symbol display device 19 shown in FIG. 7A, one special symbol determination random number “7” is determined to be a big hit. On the other hand, according to this high probability random number determination table, ten of “7”, “17”, “27”, “37”, “47”, “57”, “77”, “87”, “97” The special symbol determination random number is determined to be a big hit. Further, regardless of whether the low probability random number determination table or the high probability random number determination table is used, the special symbol determination random numbers “50”, “100”, and “150” have three special symbol determination disturbances. If it is a numerical value, it is determined as “small hit”. If the random number is other than the above, it is determined as “lost”.
Accordingly, since the random number range of the special symbol determination random number value is 0 to 254 (1 to 255 as a random number counter to be acquired), the probability of being determined to be a big hit at a low probability is 1/255, The probability of being determined to be a big hit is increased by 10 times to 1 / 25.5. In addition, the probability determined to be a small hit is 1/85 for both low and high probabilities.

FIG. 7C is a diagram showing a hit determination table that is referred to when determining whether or not the stop result of the normal symbol variation is determined to be a hit.
Specifically, the hit determination table is composed of a random time determination table in the non-short gaming state and a random number determination table in the short time gaming state, and refers to the gaming state, and in the non-short gaming state random number determination table or in the short time gaming state A random number determination table is selected, and based on the selected table and the extracted random number value for winning determination, it is determined whether it is “winning” or “losing”.
For example, according to the non-time / short game state random number determination table shown in FIG. 7C, it is determined that one hit determination random number value of “0” is a hit. On the other hand, according to the short game state random number determination table at this time, ten hit determination random numbers from “0” to “9” are determined to be winning. If the random number is other than the above, it is determined as “lost”.
Therefore, since the random number range of the hit determination random number value is 0 to 10, the probability of being determined to be a big hit at the time of non-short game state is 1/11, and the probability of being determined to be a big hit at the time of short time game state is 10 times. Up to 10/11.

FIG. 8 is a diagram showing a symbol determination table for determining a special symbol stop symbol.
8A is a symbol determination table for determining a stop symbol at the time of a big hit, and FIG. 8B is a symbol determination table for determining a stop symbol at the time of a small hit, FIG. 8C. Is a symbol determination table for determining a stop symbol at the time of losing. More specifically, the symbol determination table is also configured for each special symbol display device, and includes a symbol determination table for the first special symbol display device and a symbol determination table for the second special symbol display device.

The special symbol type (stop symbol data) is determined by the symbol determination table on the basis of the extracted jackpot symbol random value or small symbol random number value. For example, in the case of jackpot, the jackpot symbol random number value is referred to, and if the jackpot symbol random number value is “50”, “01” (first special special symbol) is determined as stop symbol data. In addition, the random number value for the small hit symbol is referred to at the time of the small hit, and if the random number value for the small hit symbol is “50”, “08” (special symbol B for small bonus) is determined as the stop symbol data. Furthermore, when it is lost, “00” (special symbol 0) is determined as stop symbol data without referring to the random number value.
Then, at the start of the change of the special symbol, an effect designating command is generated as special symbol information based on the determined special symbol type (stop symbol data). Here, the effect designating command is composed of 1-byte data, and 1-byte MODE data for identifying the control command classification, and 1 indicating the content (function) of the control command to be executed. It consists of byte data. The same applies to a start winning designation command, a variation pattern designation command, and a starting winning designation command which will be described later.

  As will be described later, the game state after the jackpot (see FIG. 9) and jackpot mode (see FIG. 10) are determined according to the type of special symbol (stop symbol data), so that the type of special symbol is terminated. It can be said that the game state and the big hit mode are determined later.

FIG. 9 is a jackpot end setting data table for determining the gaming state after the jackpot ends. According to the jackpot end setting data table shown in FIG. 9, based on the special symbol type (stop symbol data) and the winning gaming state stored in the gaming state buffer, the high probability gaming flag setting, Setting of the remaining number of fluctuations (X), setting of the short time gaming flag, and setting of the remaining number of fluctuations (J) of the short time gaming state are performed.
It should be noted that “00H” in the gaming state buffer indicating the gaming state at the time of winning the jackpot indicates gaming state information in which both the hourly gaming flag and the high probability gaming flag are not set, and “01H” indicates that the hourly gaming flag is set. Although the high probability game flag is not set, the game state information is set. “02H” is the game state information in which the short-time game flag is set but the high probability game flag is not set. "" Indicates game state information in which both the short-time game flag and the high-probability game flag are set.

As a feature of the table of FIG. 9, when the first special symbol 3 (stopped symbol data 03, corresponding to the short win) is determined in the first special symbol display device 19, it is stored in the gaming state buffer. Based on the game state at the time of winning, the setting of the short-time game flag and the number of short-time games are varied.
Specifically, in the case of the first specific special symbol 3 (stop symbol data 03),
Data indicating a gaming state in which both the high probability gaming flag and the short time gaming flag are not set in the gaming state buffer (00H: low probability gaming state, non-short time gaming state) or the high probability gaming flag is set If data indicating a gaming state in which the short-time gaming flag is not set (01H: high-probability gaming state, non-short-time gaming state) is stored, the high-probability gaming flag is set after the jackpot ends, and the probability gaming state Although the remaining fluctuation count (X) is set to 10000 times, the short-time gaming flag is not set, and the remaining fluctuation count (J) in the short-time gaming state is also set to zero. On the other hand, data indicating a gaming state in which the high probability gaming flag is not set in the gaming state buffer but the short-time gaming flag is set (02H: low-probability gaming state, short-time gaming state), or the high-probability gaming flag and the short-time gaming If data indicating a gaming state in which both of the flags are set (03H: high-probability gaming state, short-time gaming state) is stored, a high-probability gaming flag is set after the jackpot ends, and the probability gaming state The remaining number of fluctuations (X) is set to 10,000 times, the hourly gaming flag is also set, and the remaining number of fluctuations (J) in the hourly gaming state is also set to 10,000.
Thereby, the remaining number of fluctuations (J) in the short-time gaming state can be changed, and the player can enjoy what is the gaming state at the time of winning the big hit.

  FIG. 10 is a special electric accessory actuating mode determination table for determining the opening / closing conditions of the special prize opening opening / closing door 11b. Based on the special symbol type (stop symbol data), the table of FIG. 10 determines the number of operations to be performed in the jackpot game and the open state table of the big prize opening.

Here, as a feature of the special electric accessory actuating mode determination table shown in FIG. 10 in the present embodiment, the second special symbol display device 20 that is actuated when a game ball enters the second starting port 10 is used. , “Short win” is not determined.
This is because, in the non-short-time gaming state, almost no gaming ball enters the second starting port 10, but if a short hit is determined when a gaming ball enters the second starting port 10, This is because even if the short-time gaming state is provided, the player's willingness to play may be reduced. In order to prevent such a decrease in motivation for the game, the special electric accessory operating mode determination table shown in FIG. 10 is configured so that “short hit” is not determined.

FIG. 11 is an opening mode determination table showing details of the opening mode table of the big prize opening determined in FIG. 10, FIG. 11 (a) is a long hitting opening mode determination table, and FIG. The open mode determination table for use, D (c) is the open mode determination table for small hits.
Specifically, the number of round games (R), the number of times of opening (K), the opening time, and the closing time are stored in association with each other.

Here, the short hit release mode determination table in FIG. 11B and the small hit release mode determination table in FIG. 11C are different in the number of round games (R) and the number of releases (K). However, since the actual opening / closing operation of the grand prize opening / closing door 11b is the same (15 times), the opening time (0.052 seconds) and the closing time (0.052 seconds) are also the same. The person cannot distinguish whether it is a small hit or short hit from the appearance. Thereby, the pleasure which makes a player guess whether it is a small hit or a short win can be provided. However, it is not limited to setting exactly the same opening time and closing time, and any difference that cannot determine whether the player has a small hit or short hit is acceptable.
In addition, the opening time of “short win” or “small hit” (0.052 seconds) is shorter than the time (about 0.6 seconds) at which one game ball is fired as described above. Even if the open / close door 11b is opened, it is difficult to win the big prize opening 11, and the "short win" or "small win" opening mode can be said to be an "unfavorable opening mode". On the other hand, since the “long hit” release time (29.5 seconds) is longer than the time (about 0.6 seconds) at which one game ball is fired, it can be said to be an “advantageous release mode”.

FIG. 12 is a diagram showing a variation pattern determination table for determining a variation pattern of special symbols as will be described later.
Specifically, the variation pattern is determined based on the jackpot determination result, the special symbol to be stopped, the presence / absence of the short time gaming state, the number of special symbol reservations, and the random number for variation pattern by the variation pattern determination table. Based on the determined variation pattern, the variation time of the special symbol is determined, and a variation pattern designation command for transmitting the special symbol information to the effect control board 102 is generated. Therefore, it can be said that the “variation pattern” defines at least the jackpot determination result and the variation time of the special symbol. Note that the random number range for the variation pattern is set to 256 random numbers (0 to 255).

  Further, as a feature of the variation pattern determination table shown in FIG. 12, when the jackpot determination result is a loss, when the gaming state is the short-time gaming state, the special symbol variation time is set to be short. For example, when the jackpot determination result is a loss and the number of reserved balls is 2, if the game is in the short-time game state, the variation pattern 9 (shortening variation with a variation time of 3000 ms at a rate of 241/255 based on the random number value for variation pattern) ) Is determined, but if it is a non-time-saving gaming state, a variation pattern in which the variation time exceeds 3000 ms is determined. In this manner, the variation time is set to be short when the time-saving gaming state is entered.

(Description of gaming state)
Next, the gaming state when the game progresses will be described. In the present embodiment, the game progresses in any one of the “low probability gaming state”, “high probability gaming state”, “time / short gaming state”, and “non-time / short gaming state”. However, if the game state is “low probability game state” or “high probability game state” while the game is in progress, it is always “time-short game state” or “non-time-short game state”. In other words, when it is “low probability gaming state” and “short-time gaming state”, “low probability gaming state” and “non-short-time gaming state”, and “high probability gaming state” There are a case of “time saving gaming state” and a case of “high probability gaming state” and “non-time saving gaming state”.
Note that the gaming state when the game is started, that is, the initial gaming state of the gaming machine 1 is a “low probability gaming state” and is set to a “non-short-time gaming state”. Is referred to as a “normal gaming state”.

In the present embodiment, the “low probability gaming state” means that in the jackpot lottery performed on the condition that a game ball has entered the first starting port 9 or the second starting port 10, the winning probability of the jackpot is 1 / The game state set to 255. The jackpot winning here is to acquire a right to execute a “long win game” or a “short win game” which will be described later.
On the other hand, the “high probability gaming state” means a gaming state in which the jackpot winning probability is set to 1 / 25.5. Therefore, in the “high probability gaming state”, it is easier to acquire the right to execute “game per long” or “game per short” than in the “low probability gaming state”.

  In the present embodiment, the “non-temporary gaming state” means that in the normal symbol lottery performed on condition that the game ball has passed through the normal symbol gate 8, the time required for the lottery is set as long as 29 seconds, and The game state in which the opening control time of the second starting port 10 when winning is won is set to be as short as 0.2 seconds. That is, when a game ball passes through the normal symbol gate 8, a normal symbol lottery is performed, and the lottery result is determined 29 seconds after the lottery is started. If the lottery result is a win, then the second start port 10 is controlled to the second mode for about 0.2 seconds.

On the other hand, the “short-time gaming state” means that the time required for the normal symbol lottery is 3 seconds, which is shorter than the “non-short-time gaming state”, and the second starting point when winning in the win A game state in which the release control time of 10 is set to 3.5 seconds, which is longer than the “non-short game state”. Furthermore, in the “non-short game state”, the probability of winning in the normal symbol lottery is set to 1/11, and in the “short time game state”, the probability of winning in the normal symbol lottery is set to 10/11. Is set.
Therefore, in the “short-time gaming state”, the second starting port 10 is more easily controlled to the second mode as long as the game ball passes through the normal symbol gate 8 than in the “non-short-time gaming state”. Thereby, in the “short-time gaming state”, the player can advance the game without consuming the game ball.
Note that the probability of winning in the normal symbol lottery may be set so that it does not change in any of the “non-short-time gaming state” and the “time-short gaming state”.

(Explanation of hit type)
In the present embodiment, three types of big hits “long hit” and “short win” and one type of “small hit” are provided.

In the present embodiment, “long win game” means the right to execute a long hit game in the jackpot lottery performed on the condition that a game ball has entered the first start port 9 or the second start port 10. A game that is executed when the player wins the game.
In the “long game”, a round game in which the special winning opening 11 is opened is performed 15 times in total. The total opening time of the grand prize opening 11 in each round game is set to a maximum of 29.5 seconds, and if a predetermined number of game balls (for example, 9) enter the big prize opening 11 during this time, one round The game ends. In other words, “game per long” is a game in which a large amount of prize balls can be obtained because a game ball enters the big winning opening 11 and a player can obtain a prize ball according to the winning ball.

In the present embodiment, “short win game” means the right to execute a short win game in the jackpot lottery performed on condition that a game ball has entered the first start port 9 or the second start port 10. A game that is executed when the player wins the game.
In the “short win game”, a round game in which the special winning opening 11 is opened is performed 15 times in total. However, in each round game, the special winning opening 11 is opened only once, and the opening time is set to 0.052 seconds. During this time, when a predetermined number of game balls (for example, 9 balls) enter the big prize opening 11, one round game is finished. However, since the opening time of the big prize opening 11 is extremely short as described above, Hardly enters, and even if a game ball enters, only one or two game balls enter in one round game. In this “short win game”, when a game ball enters the big winning opening 11, a predetermined prize ball (for example, 15 game balls) is paid out.

In this embodiment, “small hit game” means the right to execute a small hit game in the big hit lottery performed on the condition that a game ball has entered the first start port 9 or the second start port 10. A game that is executed when the player wins the game.
Also in the “small win game”, the big prize winning opening 11 is opened 15 times as in the “short win game”. The opening time, opening / closing timing, and opening / closing mode of the big winning opening 11 at this time are the same as the above “short win game”, or the player cannot discriminate between “small win game” and “short win game” or Approximate to a difficult degree. However, when a game ball enters the special winning opening 11, a predetermined prize ball (for example, 15 game balls) is paid out in the same manner as described above.

In the present embodiment, the “long win game” and the “short win game” are referred to as “big hit game”, and the “big hit game” and the “small hit game” are collectively referred to as “special game”. That's it.
In the main control board 101, a flag is stored in the game state storage area of the main RAM 101c so as to grasp which game state is the current game state.
Also, the game state is changed from one game state to another game state after winning the jackpot and finishing the jackpot game as a result of the jackpot lottery.
In the present embodiment, a plurality of types of “big jackpots” are provided, and the type of “big jackpot” is determined according to the type of special symbol (type of jackpot symbol) determined by winning the jackpot. Then, after the jackpot ends, the subsequent gaming state changes according to the type of jackpot symbol. In the case where “small hit” is won, the gaming state such as “high probability gaming state” or “short-time gaming state” is not changed after the “small hit gaming state” ends. For example, when “small hit” is won in the “high probability gaming state”, the “high probability gaming state” continues even after the “small hit gaming state” ends.

  Next, the progress of the game in the gaming machine 1 will be described using a flowchart.

(Main processing of main control board)
The main process of the main control board 101 will be described with reference to FIG.

  When power is supplied from the power supply board 107, a system reset occurs in the main CPU 101a, and the main CPU 101a performs the following main processing.

  First, in step S10, the main CPU 101a performs an initialization process. In this process, the main CPU 101a performs a process of reading a startup program from the main ROM and initializing flags and the like stored in the main RAM in response to power-on.

  In step S20, the main CPU 101a updates the big hit symbol initial value random number and the small hit symbol initial value random number. Thereafter, the process of step S20 is repeated until a predetermined interrupt process is performed.

(Timer interrupt processing of main control board)
The timer interrupt process of the main control board 101 will be described with reference to FIG.

  A clock pulse is generated every predetermined period (4 milliseconds) by the reset clock pulse generation circuit provided on the main control board 101, thereby executing a timer interrupt process described below.

  First, in step S100, the main CPU 101a saves the information stored in the register of the main CPU 101a to the stack area.

  In step S110, the main CPU 101a updates the special symbol time counter, updates the special game timer counter such as the opening time of the special electric utility, etc., updates the normal symbol time counter, and updates the normal power release time counter. A time control process for updating various timer counters is performed. Specifically, a process of subtracting 1 from the special symbol time counter, the special game timer counter, the normal symbol time counter, and the general electricity open time counter is performed.

In step S120, the main CPU 101a performs a random number update process for the jackpot symbol random number value, the jackpot symbol random number value, and the hit determination random number value.
Specifically, each random number counter is incremented by 1 to update the random number counter. When the addition result exceeds the maximum value in the random number range, the random number counter is reset to 0. When the random number counter makes one round, the random number is updated from the initial random number value at that time.

  In step S130, the main CPU 101a performs an initial value random number update process for updating the random number counter by adding +1 to the big hit symbol initial value random number counter and the small hit symbol initial value random number counter.

In step S200, the main CPU 101a performs input control processing.
In this processing, the main CPU 101a determines whether or not there is an input to each of the general winning opening detection switch 7a, the large winning opening detection switch 11a, the first starting opening detection switch 9a, the second starting opening detection switch 10a, and the gate detection switch 8a. Input processing is performed to determine whether or not. Specifically, this will be described later with reference to FIG.

  In step S300, the main CPU 101a performs a special figure special power control process for controlling special symbols and special electric accessories. Details will be described later with reference to FIGS.

In step S500, the main CPU 101a performs a payout control process.
In this process, the main CPU 101a checks whether or not a game ball has won the big winning opening 11, the first starting opening 9, the second starting opening 10, and the general winning opening 7, and if there is a winning, Is sent to the payout control board 103.
More specifically, the general winning award winning ball counter, the large winning award winning ball counter, and the starting winning award ball counter updated in FIG. 15 to be described later are checked, and a payout number designation command corresponding to each winning award is issued. Transmit to the payout control board 103. Thereafter, predetermined data is subtracted from the prize ball counter corresponding to the sent out number designation command and updated.

  In step S600, the main CPU 101a performs data creation processing of external information data, start opening / closing solenoid data, special winning opening opening / closing solenoid data, special symbol display device data, normal symbol display device data, and a storage number designation command.

  In step S700, the main CPU 101a performs output control processing. In this process, a port output process is performed for outputting signals of the external information data, the start opening / closing solenoid data, and the special winning opening opening / closing solenoid data created in S600. Further, in order to turn on the LEDs of the special symbol display devices 19 and 20 and the normal symbol display device 21, a display device output process for outputting the special symbol display device data and the normal symbol display device data created in S600 is performed. . Further, command transmission processing for transmitting a command set in the effect transmission data storage area of the main RAM 101c is also performed.

  In step S800, the main CPU 101a restores the information saved in step S100 to the register of the main CPU 101a.

The input control processing of the main control board 101 will be described using FIG.
First, in step S210, the main CPU 101a determines whether or not a detection signal is input from the general winning opening detection switch 7a, that is, whether or not a game ball has won the general winning opening 7. When the main CPU 101a receives a detection signal from the general winning opening detection switch 7a, the main CPU 101a adds and updates predetermined data to the general winning opening prize ball counter used for the winning ball.

  In step S220, the main CPU 101a determines whether or not the detection signal from the big prize opening detection switch 11a has been inputted, that is, whether or not the game ball has won the big prize opening 11. When the main CPU 101a receives a detection signal from the big prize opening detection switch 11a, the main CPU 101a updates the big prize mouth prize ball counter used for the prize ball by adding predetermined data and updates the big prize mouth 11 for winning. The winning prize entrance counter (C) for counting the number of game balls played is added and updated.

  In step S230, the main CPU 101a determines whether or not the detection signal from the first start port detection switch 9a has been input, that is, whether or not the game ball has won the first start port 9, and determines the big hit. Predetermined data is set. Details will be described later with reference to FIG.

In step S240, the main CPU 101a determines whether or not the detection signal from the second start port detection switch 10a has been input, that is, whether or not the game ball has won the second start port 10. When the main CPU 101a receives a detection signal from the second start port detection switch 10a, the main CPU 101a updates the start port prize ball counter used for the prize ball by adding predetermined data and updates the second special symbol holding number. (U2) If the data set in the storage area is less than 4, add “1” to the second special symbol holding number (U2) storage area, and the special symbol determination random number value, jackpot symbol random number value, The random number value for the small hit symbol is extracted, and the extracted random value is stored in the second special symbol storage area.
That is, when compared with the first start port detection switch input process of FIG. 16 described later, the same process is performed although the area for storing data is different between the first special symbol storage area and the second special symbol storage area.

  In step S250, the main CPU 101a determines whether the gate detection switch 8a has input a signal, that is, whether the game ball has passed through the normal symbol gate 8. Further, when the gate detection switch 8a receives a signal, the main CPU 101a adds “1” to the normal symbol holding number (G) storage area, and from a random number range (for example, 0 to 10) prepared in advance. One hit determination random number value is extracted, and the extracted random number value is stored in the normal symbol holding storage area. However, when “4” is stored in the normal symbol holding number (G) storage area, “1” is added to the normal symbol holding number (G) storage area, or a random number for winning determination is extracted. The random number value extracted in the normal symbol holding storage area is not stored. When this process ends, the input control process ends.

The first start port detection switch input process of the main control board 101 will be described with reference to FIG.
First, in step S230-1, the main CPU 101a determines whether or not a start port signal from the first start port detection switch 9a is input via the input interface 101n.
When the start port signal from the first start port detection switch 9a is input, the process proceeds to step S230-2, and when the start port signal from the first start port detection switch 9a is not input, the first The start port detection switch input process is terminated.

  In step S230-2, the main CPU 101a performs a process of adding predetermined data to the starting opening prize ball counter used for the prize ball and updating it.

  In step S230-3, the main CPU 101a determines whether or not the data set in the first special symbol hold count (U1) storage area is less than 4. If the data set in the first special symbol hold count (U1) storage area is less than 4, the process proceeds to step S230-4, and is set in the first special symbol hold count (U1) storage area. If the data is not less than 4, the first start port detection switch input process is terminated.

  In step S230-4, the main CPU 101a adds “1” to the first special symbol hold count (U1) storage area and stores it.

  In step S230-5, the main CPU 101a outputs a random number fetch signal to the control register 101p to fetch 16-bit data from the latch register 101t, and among the fetched 16-bit data, the lower 1 byte of 8-bit data. Is obtained as a random number for determining a special symbol. Thereafter, the vacant storage units are searched in order from the first storage unit in the first special symbol storage area, and the acquired special symbol determination random number value is stored in the vacant storage unit.

  In step S230-6, the main CPU 101a obtains one jackpot symbol random value from the random number counter corresponding to the jackpot symbol random number updated in step S120, and is in the first special symbol storage area. The vacant storage unit is searched in order from the first storage unit, and the acquired jackpot symbol random number value is stored in the vacant storage unit.

  In step S230-7, the main CPU 101a obtains one small bonus symbol random number from the random number counter corresponding to the small bonus symbol random number updated in step S120, and obtains the first special symbol storage area. The vacant storage units are searched in order from the first storage unit, and the acquired random numbers for the small hit symbols are stored in the vacant storage unit.

  In step S230-8, the main CPU 101a outputs a random number fetch signal to the control register 101p to fetch 16-bit data from the latch register 101t, and among the fetched 16-bit data, the upper 1 byte of 8-bit data. Is obtained as a random number value for the fluctuation pattern. Thereafter, the vacant storage units are searched in order from the first storage unit in the first special symbol storage area, and the obtained random numbers for variation pattern are stored in the vacant storage unit.

  As described above, the special symbol determination random number value, the big hit symbol random number value, the small hit symbol random number value, and the variation pattern random number value are stored in the predetermined storage unit of the first special symbol storage area.

In step S230-9, the main CPU 101a generates a start winning designation command for indicating start point determination information in advance based on the special symbol determination random number value and jackpot symbol random number value acquired this time.
In the second start port detection switch input process, a start winning designation command is generated in the same manner as in step S230-9.

  In step S230-10, the main CPU 101a transmits the start prize designation command to the effect control board 102 in order to transmit the start prize designation command generated in the preliminary determination process in step S230-9 to the effect transmission data storage area. Set to. As a result, the sub CPUCPU 102a in the effect control board 102 that has received the start winning designation command analyzes the start winning designation command and starts to change the special symbol triggered by the winning of the game ball at the first start opening this time. A predetermined effect can be executed in advance before being performed. When this process ends, the first start port detection switch input process ends.

  With reference to FIG. 17, the special figure special power control processing of the main control board 101 will be described.

  First, in step S301, the value of the special figure special electricity processing data is loaded, the branch address is referred to from the special figure special electric treatment data loaded in step S302, and if the special figure special electric treatment data = 0, the special symbol memory determination process (step The process proceeds to S310). If the special symbol special power processing data = 1, the process proceeds to the special symbol variation processing (step S320). If the special symbol special power processing data = 2, the special symbol stop processing (step S330) is performed. If special figure special electric processing data = 3, the process moves to the big hit game process (step S340), and if special figure special electric process data = 4, the process moves to the small hit game process (step S350). If special electric processing data = 5, the processing is shifted to the big hit game ending processing (step S360). Details will be described later with reference to FIGS.

  The special symbol memory determination process of the main control board 101 will be described with reference to FIG.

  In step S <b> 310-1, the main CPU 101 a determines whether or not a special symbol variation display is being performed. If the special symbol variation display is in progress (special symbol time counter ≠ 0), the special symbol storage determination process is terminated. If the special symbol variation display is not in progress (special symbol time counter = 0), step 310 is performed. The process is moved to -2.

  In step S310-2, when the special symbol is not changing, the main CPU 101a determines whether or not the second special symbol hold count (U2) storage area is 1 or more. When the second special symbol reservation number (U2) storage area is not 1 or more, the special symbol storage determination process is terminated, and when the second special symbol reservation number (U2) storage area is determined to be “1” or more. In step S310-3, the process proceeds.

  In step S310-3, the main CPU 101a subtracts “1” from the value stored in the second special symbol hold count (U2) storage area and stores it.

  In step S310-4, the main CPU 101a determines whether or not the first special symbol hold count (U1) storage area is 1 or more. When the first special symbol reservation number (U1) storage area is not 1 or more, the special symbol storage determination process is terminated, and the first special symbol reservation number (U1) storage area is determined to be “1” or more. In step S310-5, the process proceeds.

  In step S310-5, the main CPU 101a subtracts “1” from the value stored in the first special symbol hold count (U1) storage area and stores it.

In step S310-6, the main CPU 101a performs a shift process on the data stored in the special symbol reserved storage area corresponding to the special symbol reserved number (U) storage area subtracted in steps S310-2 to S310-5. . Specifically, each data stored in the first storage unit to the fourth storage unit in the first special symbol storage area or the second special symbol storage area is shifted to the previous storage unit. Here, the data stored in the first storage unit is shifted to the determination storage area (the 0th storage unit). At this time, the data stored in the first storage unit is written in the determination storage area (0th storage unit), and the data already written in the determination storage area (0th storage unit) is stored in the special symbol hold storage. It will be erased from the area. As a result, the special symbol determination random number value, the big hit symbol random value, the small bonus symbol random value, and the variation pattern random number value used in the previous game are deleted.
In the present embodiment, the second special symbol storage area is shifted in priority to the first special symbol storage area in steps S310-2 to S310-6. One special symbol storage area or the second special symbol storage area may be shifted, or the first special symbol storage area may be shifted with priority over the second special symbol storage area.

  In step S311, the main CPU 101a writes the data (special symbol determination random number value, jackpot symbol random number value, small hit value written in the determination symbol storage area (the 0th storage unit) of the special symbol reservation storage area in step S310-6 above. The jackpot determination process is executed based on the design random number. Details will be described later with reference to FIG.

In step S312, the main CPU 101a performs a variation pattern selection process.
The variation pattern selection processing refers to the variation pattern determination table shown in FIG. Based on the above, the variation pattern is determined.

  In step S313, the main CPU 101a sets a variation pattern designation command corresponding to the determined variation pattern in the effect transmission data storage area.

  In step S314, the main CPU 101a confirms the gaming state at the start of variation, and sets a gaming state designation command corresponding to the current gaming state in the effect transmission data storage area.

  In step S315, the main CPU 101a starts the special symbol variable display on the special symbol display device 19 or 20. That is, when the information written in the processing area relates to the first hold, the special symbol display device 19 blinks, and when the information relates to the second hold, the special symbol display device 20 blinks.

  In step S316, when the main CPU 101a starts displaying the variation of the special symbol as described above, the variation time (counter value) based on the variation pattern determined in step S312 is displayed in the special symbol time counter in the special symbol time counter. set. The special symbol time counter is subtracted every 4 ms in S110.

  In step S317, the main CPU 101a sets 00H to the demonstration determination flag. That is, the demonstration determination flag is cleared.

  In step S318, the main CPU 101a sets the special symbol special processing data = 1, shifts the processing to the special symbol variation processing shown in FIG. 20, and ends the special symbol memory determination processing.

  In step S319-1, the main CPU 101a determines whether 01H is set in the demonstration determination flag. If 01H is set in the demo determination flag, the special symbol memory determination process is terminated. If 01H is not set in the demo determination flag, the process proceeds to step S319-2.

  In step S319-2, the main CPU 101a sets 01H to the demo determination flag so that the demo designation command is not set many times in step S319-3 described later.

  In step S319-3, the main CPU 101a sets a demonstration designation command in the effect transmission data storage area, and ends the special symbol memory determination process.

The jackpot determination process will be described with reference to FIG.
First, in step S311-1, the main CPU 101a determines whether or not the high probability game flag is turned on in the high probability game flag storage area. The case where the high probability gaming flag is ON is a case where the current gaming state is a high probability gaming state. If the high probability game flag is ON, the process proceeds to step S311-2. If the high probability game flag is not ON, the process proceeds to step S311-3.

  In step S311-2, when the main CPU 101a determines that the current gaming state is the high probability gaming state, the main CPU 101a selects the “high probability random number determination table”.

  In step S311-2, when the main CPU 101a determines that the current gaming state is not the high probability gaming state (low probability gaming state), the main CPU 101a selects the “low probability random number determination table”.

In step S311-4, the main CPU 101a uses the special symbol determination random number value written in the determination storage area (the 0th storage unit) of the special symbol hold storage area in step S310-6 as the step S311-2 or step S311-4. The determination is made based on the “high probability random number determination table” or “low probability random number determination table” selected in S311-3.
More specifically, when the special symbol holding storage area shifted in step S310-6 is the first special symbol storage area, the jackpot determination table for the first special symbol display device of FIG. When the special symbol storage area shifted in step S310-6 is the second special symbol storage area, refer to the jackpot determination table for the second special symbol display device in FIG. 7B. Then, based on the special symbol determination random number value, it is determined whether it is “big hit”, “small hit”, or “lost”.

  In step S 311-5, the main CPU 101 a acquires the special symbol determination disorder acquired in step S 230-5 and stored in the determination storage area (the 0th storage unit) of the special symbol hold storage area in step S 310-6. Processing for subtracting “1” from the numerical value is performed. In the present embodiment, the main CPU 101a that performs the processing constitutes a random value processing unit.

  In step S311-6, the main CPU 101a determines whether or not the jackpot determination is made as a result of the jackpot determination in step S311-4. If it is determined to be a big hit, the process proceeds to step S311-7, and if it is not determined to be a big hit, the process proceeds to step S311-10.

In step S311-7, the main CPU 101a determines the jackpot symbol random number value written in the determination symbol storage area (the 0th storage unit) of the special symbol reservation storage area in step S310-6, and determines the special symbol type ( Stop symbol data) is determined, and a jackpot symbol determination process for setting the determined stop symbol data in the stop symbol data storage area is performed.
Specifically, when the special symbol reserved storage area shifted in step S310-6 is the first special symbol storage area, the symbol determination table for the first special symbol display device (see FIG. 8A). ), When the special symbol storage area shifted in step S310-6 is the second special symbol storage area, the symbol determination table for the second special symbol display device (see FIG. 8A). ), Stop symbol data indicating the type of the special symbol to be stopped is determined based on the jackpot symbol random number value, and the determined stop symbol data is set in the stop symbol data storage area.
The determined special symbol is used to determine “big hit” or “small hit” in the special symbol stop process of FIG. 21, as will be described later, and the big hit game process of FIG. 22 or the small hit of FIG. It is also used to determine the operation mode of the big prize opening in the game process, and is also used to determine the gaming state after the big hit in the big hit game end process of FIG.

  In step S311-8, the main CPU 101a generates an effect symbol designation command corresponding to the special symbol for jackpot in order to transmit data corresponding to the special symbol to the effect control board 102, and stores it in the effect transmission data storage area. set.

In step S311-9, the main CPU 101a determines the game state at the time of winning the big win from the information set in the game state storage area (time-short game flag storage area, high probability game flag storage area), and the game state at the time of winning the big win Is set in the game state buffer. Specifically, if both the short-time game flag and the high-probability game flag are not set, 00H is set. If the short-time game flag is not set but the high-probability game flag is set, 01H is set. If the short-time game flag is set but the high-probability game flag is not set, 02H is set. If both the short-time game flag and the high-probability game flag are set, 03H is set.
In this way, apart from the game state storage area (time-short game flag storage area, high-probability game flag storage area), the game state at the time of winning the jackpot is set in the game state buffer. Since the high-probability game flag and the short-time game flag in the state storage area (time-short game flag storage area, high-probability game flag storage area) are reset, after the jackpot ends, based on the game state at the time of winning the jackpot This is because the game state storage area cannot be referred to when determining the game state at the time of the big hit. As described above, by providing a game state buffer for storing game information indicating the game state at the time of winning the big hit, apart from the game state storage area, it is possible to refer to the game information in the game state buffer after the end of the big win Based on the gaming state at the time of winning the jackpot, it is possible to newly set a gaming state after the jackpot (such as a short-time gaming state and a short-time number of times).

  In step S <b> 311-10, the main CPU 101 a determines whether or not it is determined to be a small hit. If it is determined to be a small hit, the process proceeds to step S311-11. If it is not determined to be a small hit, the process proceeds to step S311-13.

In step S311-11, the main CPU 101a determines the random symbol value for the small hit symbol written in the determination storage area (the 0th storage unit) of the special symbol holding storage area in step S310-6 to determine the type of the special symbol. And a small hit symbol determination process for setting the determined stop symbol data in the stop symbol data storage area is performed.
Specifically, referring to the symbol determination table of FIG. 8B, stop symbol data indicating the type of special symbol is determined based on the random number value for the small hit symbol, and the determined stop symbol data is determined as the stop symbol. Set in the data storage area. In the present embodiment, “small hit A” and “small hit B” are provided as the types of “small hit”. However, regardless of which “small hit” is won, the contents of the small hit game executed thereafter are exactly the same, and the “small hit A” and “small hit B” have special symbol display devices 19, Only the special symbol stopped and displayed at 20 is different.

  In step S311-12, the main CPU 101a generates an effect symbol designation command corresponding to the special symbol for small hits in order to transmit data corresponding to the special symbol to the effect control board 102, and transmits an effect transmission data storage area. Set to.

  In step S311-13, the main CPU 101a refers to the symbol determination table of FIG. 8C to determine the special symbol for losing, and sets the determined stop symbol data for losing in the stopped symbol data storage area.

  In step S311-14, the main CPU 101a generates an effect symbol designating command corresponding to the special symbol for losing in order to transmit data corresponding to the special symbol to the effect control board 102, and sets it in the effect transmission data storage area. Then, the jackpot determination process ends. In the present embodiment, the main CPU 101a that performs jackpot determination processing constitutes special determination means.

  The special symbol variation process will be described with reference to FIG.

  In step S320-1, the main CPU 101a determines whether or not the variation time set in step S316 has elapsed (special symbol time counter = 0). As a result, if it is determined that the variation time has not elapsed, the special symbol variation process is terminated and the next subroutine is executed.

  In step S320-2, when the main CPU 101a determines that the set time has elapsed, in the routine process (big hit determination process) before the special symbol variation process, the steps S311-7, S311-11, The special symbol set in S311-13 is stopped and displayed on the special symbol display devices 19 and 20. As a result, the jackpot determination result is notified to the player.

  In step S320-3, the main CPU 101a sets a symbol determination command in the effect transmission data storage area.

  In step S320-4, when the main CPU 101a starts the special symbol stop display as described above, the main CPU 101a sets the symbol stop time (1 second = 1500 counter) in the special symbol time counter. The special symbol time counter is decremented by -1 every 4 ms in S110.

  In step S320-5, the main CPU 101a sets 2 to the special symbol special electric processing data, shifts the processing to the special symbol stop processing shown in FIG. 21, and ends the special symbol variation processing.

  The special symbol stop process will be described with reference to FIG.

  In step S330-1, the main CPU 101a determines whether or not the symbol stop time set in step S320-4 has elapsed (special symbol time counter = 0). As a result, when it is determined that the symbol stop time has not elapsed, the special symbol stop process is terminated and the next subroutine is executed.

In step S330-2, the main CPU 101a determines whether or not a flag is turned on in the short-time game flag storage area. If the flag is turned on in the short-time game flag storage area, the remaining fluctuation in the short-time game state is determined. The number of times (J) is updated by subtracting 1 from the number of changes (J) stored in the storage area, and it is determined whether or not the new remaining number of changes (J) is “0”. If the remaining fluctuation count (J) is “0”, the flag stored in the time-saving game flag storage area is turned OFF, and the process proceeds to step S330-3. The remaining fluctuation count (J) is “ If not "0", the process proceeds to step S330-3 while the flag stored in the time-saving game flag storage area is kept ON.
On the other hand, if the flag is OFF in the time-saving game flag storage area, the process proceeds to step S330-3 as it is.

In step S330-3, the main CPU 101a determines whether or not a flag is turned on in the high probability game flag storage area. If the flag is turned on in the high probability game flag storage area, the high probability game state The number of remaining fluctuations (X) is updated by subtracting 1 from the number of fluctuations (X) stored in the storage area, and it is determined whether or not the new remaining number of fluctuations (X) is “0”. If the remaining number of fluctuations (X) is “0”, the flag stored in the high probability game flag storage area is turned OFF, and the process proceeds to step S330-4. If it is not “0”, the process proceeds to step S330-4 while keeping the flag stored in the high probability game flag storage area ON.
On the other hand, if the flag is turned off in the high probability game flag storage area, the process proceeds to step S330-4.

  In step S330-4, the main CPU 101a confirms the current gaming state and sets a gaming state designation command in the effect transmission data storage area.

  In step S330-5, the main CPU 101a determines whether or not it is a big hit. Specifically, it is determined whether or not the stop symbol data stored in the stop symbol data storage area is a jackpot symbol (stop symbol data = 01 to 06?). If it is determined that the jackpot symbol is determined, the process proceeds to step S330-9. If the symbol is not determined to be a jackpot symbol, the process proceeds to step S330-6.

  In step S330-6, the main CPU 101a determines whether or not it is a small hit. Specifically, it is determined whether or not the stop symbol data stored in the stop symbol data storage area is a small hit symbol (stop symbol data = 07, 08?). If it is determined that the symbol is a small hit symbol, the process proceeds to step S330-7. If it is not determined to be a small symbol, the process proceeds to step S330-8.

  In step S330-7, the main CPU 101a sets 4 in the special figure special processing data, and shifts the processing to the small hit game processing shown in FIG.

  In step S330-8, the main CPU 101a sets 0 to the special symbol special electric processing data, and shifts the processing to the special symbol memory determination processing shown in FIG.

For example, if the stop symbol data is “03”, the high probability flag is set in the high probability game flag storage area.

  In step S360-3, the main CPU 101a refers to the jackpot end setting data table shown in FIG. 9, and based on the stop symbol data loaded in S360-1 and the gaming information in the gaming state buffer, the high probability gaming state A predetermined number of times is set in the remaining number of fluctuations (X) storage area. For example, if the stop symbol data is “03”, 10000 is set in the remaining fluctuation count (X) storage area of the high probability gaming state.

  In step S360-4, the main CPU 101a refers to the jackpot end setting data table shown in FIG. 9, and stores the short-time game flag based on the stop symbol data loaded in S360-1 and the game information in the game state buffer. Whether or not to set the short-time game flag in the area is processed. For example, when the stop symbol data is “03” and the game information in the game state buffer is 00H or 01H, the time-short game flag is not set in the time-short game flag storage area, but the game information in the game state buffer is 02H or When it is 03H, the time-short game flag is set in the time-short game flag storage area.

When the game information is 02H or 03H, 10000 times is set in the remaining change count (J) storage area of the time-short game state.

  In step S360-6, the main CPU 101a confirms the gaming state and sets a gaming state designation command in the effect transmission data storage area.

  In step S360-7, the main CPU 101a sets 0 to the special symbol special electric processing data, and shifts the processing to the special symbol memory determination processing shown in FIG.

  The ordinary power transmission control process will be described with reference to FIG.

  First, in step S401, the value of the ordinary map electric power processing data is loaded, and the branch address is referenced from the loaded ordinary electric power processing data in step S401. The process is moved to (Step S410), and if the ordinary power / general power process data = 1, the process is moved to the ordinary electric accessory control process (Step S420). Details will be described later with reference to FIGS.

  The normal symbol variation process will be described with reference to FIG.

  In step S410-1, the main CPU 101a determines whether or not the normal symbol variation display is being performed. If the normal symbol variation display is being performed, the process proceeds to step S410-13, and if the normal symbol variation display is not being performed, the process proceeds to step S410-2.

  In step S410-2, the main CPU 101a determines whether or not the normal symbol hold count (G) stored in the normal symbol hold count (G) storage area is 1 or more when the normal symbol fluctuation display is not being performed. To do. When the number of holds (G) is “0”, the normal symbol variation display is not performed, so the normal symbol variation process is terminated.

  In step S410-3, if the main CPU 101a determines in step S410-2 that the normal symbol hold count (G) is equal to or greater than “1”, it is stored in the special symbol hold count (G) storage area. A new hold number (G) obtained by subtracting “1” from the stored value (G) is stored.

  In step S410-4, the main CPU 101a performs a shift process on the data stored in the normal symbol storage area. Specifically, each data stored in the first storage unit to the fourth storage unit is shifted to the previous storage unit. At this time, the data stored in the previous storage unit is written into a predetermined processing area and is erased from the normal symbol holding storage area.

In step S410-5, the main CPU 101a determines the winning random number stored in the normal symbol holding storage area. When a plurality of winning random numbers are stored, the winning random numbers are read in the stored order.
Specifically, with reference to the hit determination table shown in FIG. 7C, it is determined whether or not the extracted hit determination random number value is checked against the above table. For example, according to the above table, one hit determination random value of “0” out of the hit random numbers “0” to “10” is determined to be a hit in the non-short-time gaming state, and the short-time gaming state For example, ten hit determination random numbers from “0” to “9” out of the hit random numbers from “0” to “10” are determined to be wins, and the other random numbers are determined to be lost.

In step S410-6, the main CPU 101a refers to the result of the determination of the winning random number in step S205. If the winning determination is made, the main CPU 101a sets the winning symbol in step S410-7 and determines that it is lost. In this case, a lost symbol is set in step S410-8.
Here, the winning symbol is a symbol in which the LED is finally turned on in the normal symbol display device 21, and the lost symbol is a symbol in which the LED is finally turned off without being turned on. The winning symbol set is to store a command to turn on the LED in the normal symbol display device 21 in a predetermined storage area, and the lost symbol set is a command to turn off the LED in the normal symbol display device 21. Is stored in a predetermined storage area.

  In step S410-9, the main CPU 101a determines whether or not a flag is turned on in the time-saving game flag storage area. When the flag is turned on in the short-time game flag storage area, the game state is in the short-time game state, and when the flag is not turned on, the game state is in the non-short-time game state. Is the time.

  If the main CPU 101a determines that the flag is ON in the short-time game flag storage area, in step S410-10, the main CPU 101a sets a counter corresponding to 3 seconds to the normal symbol time counter, and the short-time game flag storage area If it is determined that the flag is not turned on, a counter corresponding to 29 seconds is set in the normal symbol time counter in step S410-11. By the process of step S410-10 or step S410-11, the time for displaying the normal symbol variation is determined. The normal symbol time counter is subtracted every 4 ms in step S110.

  In step S410-12, the main CPU 101a starts normal symbol fluctuation display on the normal symbol display device 21. The normal symbol variation display is to flash the LED at a predetermined interval in the normal symbol display device 21 and give the player an impression as if it is currently being drawn. This normal symbol variation display is continuously performed for the time set in step S410-10 or step S410-11. When this process ends, the normal symbol variation process ends.

  In step S410-13, if the main CPU 101a determines in step S410-1 that the normal symbol variation display is being performed, the main CPU 101a determines whether or not the set variation time has elapsed. That is, the normal symbol time counter is subtracted every 4 ms, and it is determined whether the set normal symbol time counter is zero. As a result, if it is determined that the set variation time has not elapsed, it is necessary to continue the variation display as it is, so that the normal symbol variation process is terminated and the next subroutine is executed.

  In step S410-14, when the main CPU 101a determines that the set fluctuation time has elapsed, the main CPU 101a stops the fluctuation of the normal symbol in the normal symbol display device 21. At this time, the normal symbol display device 21 stops and displays the normal symbol (winning symbol or lost symbol) set by the previous routine processing. As a result, the result of the normal symbol lottery is notified to the player.

  In step S410-15, the main CPU 101a determines whether or not the set normal symbol is a winning symbol. If the set normal symbol is a winning symbol, the main CPU 101a determines in step S410-16 that the normal symbol is normal. Fig. Ordinary power processing data = 1 is set, and the processing is shifted to the normal electric accessory control processing. If the set normal symbol is a lost symbol, the normal symbol variation processing is terminated as it is.

  The normal electric accessory control process will be described with reference to FIG.

  In step S420-1, the main CPU 101a determines whether or not the time-saving game flag is turned on in the time-saving game flag storage area.

  In step S420-2, if the main CPU 101a determines that the time-saving game flag is ON in the time-saving game flag storage area, that is, if the current gaming state is the time-saving gaming state, the main power release time counter Set a counter corresponding to 3.5 seconds.

  In step S420-3, when the main CPU 101a determines that the time-saving game flag is not turned on in the time-saving game flag storage area, the main CPU 101a sets a counter corresponding to 0.2 seconds to the public power open time counter.

  In step S420-4, the main CPU 101a starts energizing the start port opening / closing solenoid 10c. Thereby, the 2nd starting port 10 will open and it will be controlled by the 2nd mode.

  In step S420-5, the main CPU 101a determines whether or not the set public power open time has elapsed. That is, the normal power open time counter is subtracted every 4 ms, and it is determined whether or not the set normal power open time counter = 0.

  In step S420-6, when it is determined that the set normal power release time has elapsed, the main CPU 101a stops energization of the start opening / closing solenoid 10c. As a result, the second starting port 10 returns to the first mode, and it becomes impossible or difficult to enter the game ball again, and the auxiliary game that has been executed ends.

  In step S420-7, the main CPU 101a sets the ordinary figure normal electricity processing data = 0 and shifts the processing to the ordinary symbol variation process of FIG. 26, and the ordinary electric accessory control process ends.

  Next, the outline of the effect control board 102 will be briefly described.

  When the effect control board 102 receives the command transmitted from the main control board 101, a command reception interrupt process of the effect control board 102 occurs, and the received command is stored in the reception buffer.

  Then, the sub CPU 102a in the effect control board 102 analyzes the received command and generates various data corresponding to each command in the timer interrupt process of the effect control board 102 performed every 2 ms. Thereafter, the generated various data is transmitted to the image control board 105 and the lamp control board 104.

  For example, when the sub CPU 102a in the effect control board 102 receives the change pattern designation command from the main control board 101, the sub CPU 102a analyzes the content of the received change pattern designation command, and displays the liquid crystal display device 13, the audio output device 18, and the effect illumination. Data for causing the device 16 and the effect accessory devices 14 and 15 to execute a predetermined effect is generated, and the data is transmitted to the image control board 105 and the lamp control board 104.

  Next, the outline of the image control board 105 and the lamp control board 104 will be briefly described.

  When controlling the liquid crystal display device 13 on the image control board 105, the audio CPU reads out the audio output device control program from the audio ROM based on the received data, and controls the output of the audio in the audio output device 18. When data is transmitted from the effect control board 102 to the image control board 105, the image CPU reads a program from the image ROM and controls the image display on the liquid crystal display device 13 based on the received effect command.

  In the lamp control board 104, the effect actor device operation program is read based on the received data to control the operation of the effect agent devices 14, 15, and the effect lighting device control based on the received effect data. The program is read and the lighting device for effect 16 is controlled.

  As a result, since the exclusive OR data of a plurality of upper bits is fed back to the lower bits in the 16-bit random number update circuit 101s, the random value is not updated by +1, but the discrete values are updated, The irregularity of random numbers used in games can be increased. Furthermore, since the 8-bit random value is acquired from the updated 16-bit random value, the same random value is continuously generated, and the irregularity of the random value can be further improved. .

  In the present embodiment, one random number value fetched by the latch register in the hardware configuration is used separately for the special symbol determination random value and the variation pattern random value, but the special symbol determination random value is used. It may be used only for

  In this embodiment, a part of the data (lower byte) captured by the latch register in the hardware configuration is used as a special symbol determination random value. However, instead of the special symbol determination random value, the jackpot symbol is used. You may use for the random number value for fall determination which determines shifting to a low probability game state from a random value, a random number value for a small hit design, and a high probability game state.

  Furthermore, in this embodiment, a part of the data (upper byte) captured by the latch register in the hardware configuration is used as the random number value for the variation pattern. It may be used for numerical values.

  In the present embodiment, the special symbol determination random number value and the variation pattern random number value are generated by a hardware configuration, and the other random number values are generated by a software program. It may be generated by a hardware configuration.

  When multiple random values are generated by hardware configuration, all random values generated by hardware configuration are generated using a shift register that feeds back the exclusive OR data of upper bits to lower bits. However, the predetermined random number value may be generated by using a counter circuit that adds the random number values one by one.
