Description

  The present invention relates to a gaming machine, and is particularly suitable for use in a bullet ball gaming machine that plays a game based on a generated random number.

In a ball game machine (pachinko machine), a random number is generated, it is determined to which area of the lottery table the generated random number belongs, and the result of the game (whether it is a big hit) based on the determined area Etc. are determined.
As a method for generating such a random number, conventionally, an initial value is updated, and a random number is generated based on the updated initial value. When updating the initial value in this way, if the initial value is updated to a predetermined value (for example, zero), the following illegal actions are performed by the hanging board attached to the back surface of the gaming machine or the like. There is a risk that In other words, there is a risk that an illegal act of arbitrarily generating a special gaming state may be performed by outputting a reset signal and forcing the initial value of the random number to zero and then outputting a pseudo winning signal at a predetermined timing. .

  Therefore, there has been a technique for storing random numbers obtained immediately before resetting and using the stored random numbers as initial values (see Patent Document 1). In this technology, using a backup power supply, the stored random number is not erased even after the main power of the gaming machine is shut down, and the initial value of the random number when the main power is turned on is stored. The random number that has been set is made.

JP 2003-38806 A

However, in the above-described conventional technology, if the stored random number is rewritten between the time when the main power supply of the gaming machine is turned off and the power is turned on again, the above-described illegal acts are prevented. There was a problem that it was difficult.
The present invention has been made in view of such problems, and when an initial value is updated and a random number is generated based on the updated initial value, an illegal operation performed on the generated random number is conventionally performed. It aims to be able to suppress more.

In order to achieve this object, the invention according to claim 1 is a random number generating means for generating a random number for each predetermined value from an initial value, wherein the random number is generated without updating the initial value. When the random number is generated from the initial value and all possible random numbers are generated, the second random number generating means for updating the initial value and the random number generating operation by the first random number generating means Auxiliary power supply means for supplying power to the first random number generation means while the main power is cut off, in order to continue even if the main power supply of the gaming machine is cut off, and the second A random number acquisition unit that acquires a random number generated by the first random number generation unit after an operation of resetting an initial value of a random number in the random number generation unit is performed, and a random number is acquired by the random number acquisition unit To a value based on the random number Random number changing means for changing the initial value of the random number in the second random number generating means, and when a game ball wins a winning opening formed in the game board, the first random number generating means and the second random number generating means And a game result judging means for judging a game result using a random number generated in at least one of the above.
In such a configuration, a random number generating means (first random number generating means) for generating a random number from the initial value without updating the initial value, and a random number generating means (second random number generating means for generating a random number from the initial value while updating the initial value) Random number generating means). The first random number generator is supplied with backup power even when the main power is turned off. Thereby, even if the main power is turned off, the first random number generation means continues to generate random numbers. Then, after the operation of resetting the initial value of the random number in the second random number generation unit is performed, the value based on the random number generated by the first random number generation unit is used as the initial value of the random number in the second random number generation unit. And Therefore, the value set as the initial value of the random number in the second random number generation means can be determined in advance. Therefore, when an initial value is updated and a random number is generated based on the updated initial value, an illegal operation performed on the generated random number can be suppressed more than in the past.

According to a second aspect of the present invention, there is provided storage means for storing state identification information for identifying a state of the gaming machine immediately before the main power supply is shut off, and state identification information stored by the storage means. However, in order to continue even if the main power supply is cut off, the second auxiliary power supply means for supplying power to the storage means while the main power supply is turned off, and the main power supply are connected again. State match determination means for determining whether or not the state of the gaming machine after being turned on matches the state of the gaming machine immediately before the main power supply is shut off based on the state identification information; and When it is determined by the coincidence determining means that the state of the gaming machine after the main power is turned on again and the state of the gaming machine immediately before the main power is cut off, the second random number generation Reset to reset initial value of random number in means And the random number acquisition means acquires the random number generated by the first random number generation means after the initial value of the random number in the second random number generation means is reset by the reset means. It is characterized by.
In such a configuration, the state of the gaming machine immediately before the main power supply is cut off is retained even after the main power supply is cut off, and the state of the gaming machine immediately before the main power supply is cut off and the main power supply is turned on again. Compare the state of the gaming machine when it is played. If these game states do not match, it is determined that there has been some change in the gaming machine between the time when the main power supply is turned off and the time when it is turned on again. Reset the initial value. A value based on the random number generated by the first random number generation unit after the initial value of the random number in the second random number generation unit is reset in this way is set as the initial value of the random number in the second random number generation unit. Therefore, the initial value of the random number in the second random number generation means is not determined in advance after detecting that there has been some change in the gaming machine between the time when the main power supply is shut off and the time when it is turned on again. Can be changed to a value.

According to a third aspect of the present invention, the state coincidence determining means matches the state of the gaming machine after the main power is turned on again with the state of the gaming machine immediately before the main power is shut off. If it is determined, it has a setting means for setting the random number generation operation of the second random number generation means in a state immediately before the main power supply is shut off.
In such a configuration, when the state of the gaming machine immediately before the main power is turned off matches the state of the gaming machine when the main power is turned on again, the main power is turned off and then turned on again. It is determined that there is no change in the gaming machine until this time, and the random number generation operation of the second random number generation means is set to the state immediately before the main power supply is shut off. Therefore, it is possible to prevent the initial value of the random number in the second random number generation means from being changed more than necessary.

According to a fourth aspect of the present invention, there is provided an operation unit operated to forcibly reset an initial value of a random number in the second random number generation unit, and an initial value of a random number in the second random number generation unit. The operation determining means for determining whether or not the operation for forcibly resetting the operation has been performed by the operating means, and the operation determining means forcing the initial value of the random number in the second random number generating means When it is determined that an operation for resetting has been performed, the second random number generation unit includes a reset unit that resets an initial value of a random number, and the random number acquisition unit uses the reset unit to The random number generated by the first random number generation means is acquired after the initial value of the random number in the random number generation means is reset.
In such a configuration, when an operation for forcibly resetting the initial value of the random number in the second random number generation unit is performed, the initial value of the random number in the second random number generation unit is reset. A value based on the random number generated by the first random number generation unit after the initial value of the random number in the second random number generation unit is reset in this way is set as the initial value of the random number in the second random number generation unit. Therefore, the initial value of the random number in the second random number generation means can be changed to a value that is not predetermined according to the intention of the administrator of the gaming machine.

The invention according to claim 5 further includes a generation unit that, when a random number is acquired by the random number acquisition unit, generates an initial value of a random number in the second random number generation unit based on the random number, The random number changing means changes the initial value of the random number in the second random number generating means to the initial value generated by the generating means.
In such a configuration, the initial value of the random number in the second random number generation unit is based on the random number generated by the first random number generation unit after the operation of resetting the initial value of the random number in the second random number generation unit is performed. A value is generated, and the generated value is set as an initial value of a random number in the second random number generation means. Therefore, the initial value of the random number in the second random number generation means can be determined more flexibly.
Here, as described in claim 6, the first random number generation means is a hardware random number generation means, and the second random number generation means generates a random number according to the operation of the computer program. It can be a means.

  According to the present invention, when an initial value is updated and a random number is generated with reference to the updated initial value, an illegal operation performed on the generated random number can be suppressed more than in the past.

Hereinafter, a first embodiment of the present invention will be described in detail with reference to the drawings. In the present embodiment, a so-called first-class pachinko machine will be described as an example of a gaming machine.

The nail 101 and the windmills 102a and 102b are provided at predetermined positions in the game area 115. For example, the movement of the game ball entering the game area 115 and moving from the top to the bottom in FIG. Or the winning of the game ball to the general winning port 111, the start winning port 112, and the big winning port 113 and the passing of the game ball to the normal symbol operating gate 103 are adjusted.

  The special symbol display device 106 is provided on the side of the inner rail 109, and includes, for example, a 7-segment LED 116 that displays the special symbol and four LEDs 117 that display the number of winnings to the starting winning port 112 of the game ball. It is prepared for. Here, the special symbol is a symbol for indicating whether or not to generate a “hit” in accordance with the result of a lottery performed with the winning of the game ball at the start winning port 112 as a trigger.

  In the present embodiment, the 7-segment LED 116 is caused to emit light based on the winning of the game ball at the start winning opening 112, and any of “0” to “7”, which is a special symbol corresponding to “big hit”, and “losing” "-" Which is a special symbol corresponding to "" is variably displayed, and then one of these special symbols is stopped and displayed.

  The four LEDs 117 for displaying the number of lottery results held based on the winning of the game ball at the start winning opening 112 sequentially emit light each time the game ball wins the start winning opening 112, and also display a special symbol change display. Turns off sequentially when starting. In other words, the number of light emission of the four LEDs 117 corresponding to the upper limit value of the number of holdings is notified to the player of the current number of holdings of the lottery result based on winning of the game ball at the start winning opening 112. As described above, in this embodiment, the upper limit value of the number of holds of the lottery result based on the winning of the game ball to the start winning opening 112 is set to four. Then, when the number of reserves is four and a game ball is won at the start winning opening 112, the number corresponding to winning at the start winning opening 112 without performing a lottery based on the winning of the game ball. Only to play the prize ball.

  The decorative symbol display device 107 is provided at a substantially central position of the game area 115 so that the player can easily recognize it. For example, the decorative symbol display device 107 includes a liquid crystal display device that displays effect images such as decorative symbols. . The decorative symbol display device 107 displays three decorative symbols displayed in a horizontal row in decorative symbol display areas 118 a to 118 c in the display screen 118 of the decorative symbol display device 107. Here, the decorative symbol is a symbol for visually producing the result of the lottery.

  In the present embodiment, for example, “0” to “9” and “A” to “F” are displayed in the decorative symbol display areas 118 a to 118 c as “0”, “1”, “2”, “ 3 ”,“ 4 ”,“ 5 ”,“ 6 ”,“ 7 ”,“ 8 ”,“ 9 ”,“ A ”,“ B ”,“ C ”,“ D ”,“ E ”,“ F ” In this order, after variably displaying from the top to the bottom of FIG. 1, any one of “0” to “9” and “A” to “F” is stopped in the decorative symbol display areas 118a to 118c. It is made to display. Then, when a combination of specific decorative symbols is stopped and displayed in the decorative symbol display areas 118a to 118c, the jackpot is set. On the other hand, when the combination of the decorative symbols stopped and displayed in the decorative symbol display areas 118a to 118c does not correspond to any of the specific decorative symbol combinations, it is “lost”.

In the present embodiment, the meanings of the special symbols that are stopped and displayed on the special symbol display device 106 and the decorative symbols that are stopped and displayed on the decorative symbol display device 107 are made to coincide with each other. For example, if the special symbol that is stopped and displayed on the special symbol display device 106 indicates “big jackpot”, the decorative symbol that is stopped and displayed on the decorative symbol display device 107 also indicates “big jackpot”. (I.e., a combination of the specific decorative symbols).
As described above, in the present embodiment, the special symbol and the decorative symbol are displayed in conjunction with each other so that no contradiction occurs when the game result is displayed.

  In addition, the decorative symbol display device 107 displays not only the decorative symbol but also a background image as a background of the decorative symbol and an accompanying image such as a character image for giving the player a sense of expectation of jackpot as an effect image. To do. As the accompanying image, one or both of a still image and a moving image (for example, when a character image fluctuates within a stationary background image) can be displayed. Specifically, the decorative symbol display device 107 displays the decorative symbols in the decorative symbol display areas 118a to 118c in a variable manner and displays accompanying images such as a background image and a character image (in some cases). After that, when the same decorative design is stopped and displayed in the decorative design display areas 118a and 118c and a so-called reach state is formed, the display is switched to an accompanying image prepared for the reach state and the expectation of “big hit” is played. After giving to the user, the remaining decorative symbols that are changing are stopped and displayed in the decorative symbol display area 118b. As described above, the decorative symbol display device 107 performs various displays (effects) so that the player can have a sense of expectation for “big hit”.

Below the decorative symbol display device 107, an ordinary electric accessory 104 is provided. The ordinary electric accessory 104 opens and closes to guide the game ball to the start winning opening 112.
A big prize opening 113 is formed below the ordinary electric accessory 104. The big prize opening 113 becomes a “hit” and when the game shifts to a special game, the big prize opening door 120 falls and opens. In the present embodiment, a maximum of 15 unit games are executed in a special game. More specifically, during a unit game, when a game ball passes through a specific area (so-called V zone) 121 formed in the big prize opening 113, it may shift to the next unit game. As much as possible, a maximum of 15 unit games are executed. In the present embodiment, the specific area 121 is formed in the special winning opening 113, but the specific area 121 is not necessarily formed. In this case, when shifting to the special game, it is guaranteed that 15 unit games will be executed.

When the player rotates the launch handle 131, the game ball is guided toward the game area 115 by being guided by the inner rail 109 and the outer rail 110 at a speed corresponding to the rotation angle.
Further, speakers 133 for reproducing and outputting sound effects are provided on both sides of the ball removal button 128b.

(Outline of specified games)
Here, an outline of the prescribed game in the gaming machine 100 will be described.
First, in the state where the rented game balls (rental balls) are placed on the ball tray 128a, when the player turns the launch handle 131 in the clockwise direction toward FIG. 1, the game balls are moved to the game area. Fired at 115. The game ball that has entered the game area 115 collides with the nail 101, the windmill 102, etc. formed in the game area 115, and moves in the game area 115 from top to bottom while moving irregularly. .

  When the game ball wins the start winning opening 112, a predetermined number of prize balls (four prize balls in this embodiment) are paid out to the ball tray 128a, and the special symbol display device 106 and the decorative symbol display device 107 are used. However, the change display of the symbol is started. Thereafter, when a predetermined special symbol is stopped and displayed on the special symbol display device 106 and a combination of predetermined decorative symbols (for example, the same decorative symbol) is stopped and displayed on the decorative symbol display device 107, a “big hit” is obtained. A game shifts to a game.

  In the special game, the big prize opening door 120 falls down and the big prize opening 113 is opened. Each time a game ball wins the open big winning opening 113, a predetermined number of prize balls (15 prize balls in this embodiment) are paid out. In this embodiment, when the grand prize opening 113 is opened for 29.5 seconds or when a specific number of game balls are won in the grand prize opening 113, the grand prize opening door 120 is raised. Then, the big prize opening 113 is closed. In the following description, when the specific number is 10, that is, either the big prize opening 113 is opened for 29.5 seconds or ten game balls are won in the big prize opening 113. A description will be given by taking as an example a case where the grand prize opening door 120 is raised when the state is reached.

When the game ball passes through a specific area (so-called V zone) formed in the big prize opening 113 while the big prize opening 113 is opened as described above, the big prize opening 113 is obtained. Will open again. In the present embodiment, the opening / closing operation of the grand prize winning opening 113 is performed up to 15 times. In other words, as described above, in the special game, the unit game is played a maximum of 15 times.
In this way, when a special game is executed, a large amount of prize balls are paid out in a short period of time, and a great merit can be given to the player.

  When the game ball passes through the normal symbol operation gate 103, the normal symbol display device 108 (7-segment LED 122) starts to display the normal symbol in a variable manner. Thereafter, when a predetermined normal symbol (“7” in the present embodiment) is stopped and displayed on the normal symbol display device 108 (7-segment LED 122), the normal electric accessory 104 opens and closes. When the ordinary electric accessory 104 is opened, the game ball can win the start winning opening 112 without passing between nails (so-called life nails) above the start winning opening 112.

In the present embodiment, after the special game is executed, the mode is shifted to either the “probability change mode” or the “time reduction mode”.
Here, the “probability change mode” is a mode in which a “big hit” is made and a state in which the probability of becoming a “big hit” is higher than that in the “normal mode” after a special game is executed. Further, in this “probability change mode”, after the execution of the special game, until the next special game starts, the operation of the ordinary electric accessory 104 is made different from that in the “normal mode”, and the start winning port 112 is displayed. It is also designed to create a state where game balls are easy to win.

On the other hand, the “short-time mode” is a “big hit”, and after the special game is executed, for example, until the game about 100 special symbol fluctuations is executed, the operation of the ordinary electric accessory 104 is “normal mode”. In other words, the game ball forms a state where it is easy to win the start winning opening 112, and when the predetermined number of games are executed, the mode returns to the “normal mode”.
In these “probability mode” and “time reduction mode”, the change display time of the special symbol and the decorative symbol is made shorter than that in the “normal mode”.

  As described above, when the transition to the “probability change mode” is performed after the execution of the special game, it is possible to prevent the holding ball from being reduced as much as possible until the next special game is started. Further, even when the mode is shifted to the “short time mode”, it is possible to prevent the holding ball from being reduced as much as possible for a while after the execution of the special game.

  When a game ball wins the general winning opening 111, a predetermined number of prize balls (four prize balls in this embodiment) are paid out to the ball tray 128a. If the game ball has not won any winning opening, the game ball flows into the out opening 114.

(System configuration)
Next, a system configuration such as an internal configuration of the gaming machine 100 will be described. FIG. 2 is a block diagram illustrating an example of a system configuration of the gaming machine 100.
Inside the housing of the gaming machine 100, there are a main control board 201, a sub control board 202 connected to the main control board 201, a winning hole board 203, an LED drive board 204, a launch control board 205, a payout control board 206, A power receiving board 207, an electrical decoration board 208, a random number control board 221 and the like are arranged.

(Main control board 201)
The main control board 201 is provided with a main CPU 201a, ROM 201b, RAM 201c, and interface circuit (I / F circuit) 201d, which are connected to each other via a bus 201e.

  The main CPU 201a reads (fetches), interprets (decodes), and executes instructions constituting the program. And main CPU201a reads the program, data, etc. which are memorize | stored in ROM201b, and controls the whole gaming machine 100 based on these.

  The ROM 201b stores programs, data, and the like necessary for the main CPU 201a to perform processing shown in FIGS. 6 to 11 described later and other game controls. The RAM 201c is used as a work area when the main CPU 201a performs various controls and temporarily stores data and the like.

  The I / F circuit 201d is a signal performed between the main control board 201, the sub control board 202, the winning hole board 203, the LED drive board 204, the launch control board 205, the payout control board 206, and the random number control board 221. The timing is controlled during transmission / reception. However, between the main control board 201 and the sub control board 202, transmission of signals from the main control board 201 to the sub control board 202 is performed, but transmission of signals from the sub control board 202 to the main control board 201 is not performed. Not done. That is, only one-way transmission is possible.

  In addition, the I / F circuit 201 d receives supply of predetermined power from the power supply device (main power supply) 209 disposed inside the housing of the gaming machine 100 via the power receiving board 207. With this power, the main control board 201 can perform various processes described later.

More specifically, when a random number is generated for each predetermined value (for example, +1) from the initial value and all the generated random numbers are generated, the normal symbol of the normal symbol is updated according to the random number generation program that updates the initial value. A random number for updating the initial value of the random number related to the success / failure is generated. Here, the “F” is a natural number.

  In the present embodiment, when there is no designation by the initialization processing unit 315 described later, the initial value of the random number for updating the initial value of the random number related to the normal design and the initial value of the random number related to the normal design is determined. For example, the value is updated to a value obtained by adding a predetermined number to the previous initial value. On the other hand, when there is designation by an initialization processing unit 315 described later, these initial values are updated to the designated values.

In the present embodiment, the period for generating random numbers related to whether or not the normal symbol is generated (the time required to generate all the random numbers in the range of “0” to “E”) and the initial value of the random number related to whether or not the normal symbol is determined. Periods for generating random numbers for updating values (time required to generate all random numbers in the range of “0” to “F”) are made different from each other.
In the following description, a random number for updating an initial value of a random number related to whether or not a normal symbol is correct is referred to as an initial value random number as necessary.

  In the present embodiment, as described above, a random number related to whether or not a normal symbol is appropriate is obtained. When no random number is stored in the normal symbol random number storage area (that is, when it is not necessary to hold the normal symbol lottery result), the normal symbol lottery unit 309 uses the acquired random number as the winning determination unit. It outputs to 310.

On the other hand, when the number of random numbers stored in the normal symbol random number storage area is three or less, the normal symbol lottery unit 309 stores the acquired random number in the normal symbol random number storage area. As described above, in the present embodiment, up to four random numbers acquired by the normal symbol lottery unit 309 can be stored in the normal symbol random number storage area, and the random number storage order can be identified. . Then, the normal symbol lottery unit 304 outputs the random number stored earliest in the normal symbol random number storage area to the winning determination unit 310 and deletes the output random number from the normal symbol random number storage region.
The normal symbol lottery unit 309 is realized by using, for example, the main CPU 201a, the ROM 201b, and the RAM 201c provided on the main control board 201.

(Winning determination unit 310)
Based on the random number value output from the normal symbol lottery unit 309, the winning determination unit 310 determines whether the lottery result by the normal symbol lottery unit 309 corresponds to “win” or “losing”. This determination is performed using, for example, a lottery table.

In the present embodiment, the probability of being “winning” is significantly higher in the case of transitioning to the “probability mode” or “short-time mode” than in the case of playing the game in the “normal mode”. In addition, the contents of each lottery table used in the winning determination unit 310 are set. As a result, the probability of winning a normal symbol when the mode is shifted to the “probability change mode” or the “time reduction mode” is increased. Therefore, when the mode is shifted to the “probability change mode” or the “time reduction mode”, the opening frequency of the ordinary electric accessory 104 becomes higher as much as possible than when the game is played in the “normal mode”. The game can be advanced without reducing the ball.
The normal symbol lottery unit 309 is realized by using, for example, the main CPU 201a, the ROM 201b, and the RAM 201c provided on the main control board 201.

(Normal symbol display instruction unit 311)

  In the present embodiment, when the probability variation flag or the time reduction flag stored in the flag storage unit 302 is turned on (in the case of shifting to the “accuracy variation mode” or “time reduction mode”), The normal symbol variation display time is much shorter than when the game is not turned on (as compared to when the game is played in the “normal mode”).

If the result of the determination by the winning determination unit 310 is “winning”, for example, “7” is determined as a normal symbol to be stopped and displayed on the normal symbol display device 108. On the other hand, in the case of “losing”, for example, “−” is determined as a normal symbol to be stopped and displayed on the normal symbol display device 108.
The normal symbol display instruction unit 311 is realized by using, for example, a main CPU 201 a ROM 201 b and a RAM 203 c provided on the main control board 201.

Specifically, in the present embodiment, the ordinary electric accessory driving instruction unit 312 varies the operation mode of the ordinary electric accessory 104 according to the state of the probability variation flag and the time reduction flag stored in the flag storage unit 302. I have to.

  Further, when the probability change flag or the time reduction flag stored in the flag storage unit 302 is turned on (the case where the flag is changed to the “probability change mode” or “time reduction mode”), they are turned on. The operation mode of the ordinary electric accessory 104 is determined so that the game ball can be easily won at the start winning opening 112 than when the game is not performed in the “normal mode”. .

Then, the ordinary electric accessory drive instructing unit 312 transmits the ordinary electric accessory release signal indicating the determined operation mode to the winning prize opening board 203. Thereby, the ordinary electric accessory 104 operates in the operation mode indicated by the ordinary electric accessory release signal.
The ordinary electric accessory driving instruction unit 312 is realized by using, for example, a main CPU 201 a ROM 201 b and a RAM 203 c provided on the main control board 201.

In the present embodiment, the game state is stored as an example of the state of the gaming machine 100. More specifically, the gaming state storage unit 314 generates the state of the flag stored in the flag storage unit 302 and the special symbol lottery unit 304 and the normal symbol lottery unit 309 when the power switch 219 is turned off. The value of the random number being held is held as the gaming state in the gaming machine 100 immediately before the supply of power from the power supply device 209 is cut off.
Since the gaming state storage unit 314 is supplied with power from the auxiliary power supply device 222, the gaming state storage unit 314 can also be connected to the gaming machine 100 even after the power switch 219 is turned off and the power supply from the power supply device 209 is cut off. The game state can be maintained.

Further, here, the state of the flag stored in the flag storage unit 302, the value of the random number generated in the special symbol lottery unit 304 and the normal symbol lottery unit 309, and the like are held as the gaming state of the gaming machine 100. However, the gaming state of the gaming machine 100 held by the gaming state storage unit 314 is not limited to this.
The gaming state storage unit 314 is realized, for example, by using a RAM 201c provided on the main control board 201.

The normal symbol lottery unit 309 also has the software random number as described above. That is, the normal symbol lottery unit 309 generates the random number generator 309a for determining whether or not the random number in the range of “0” to “E” is generated as a random number related to whether or not the normal symbol is generated, and the random number generator 304 for determining whether or not it is correct. An initial value random number generator 309b for generating random numbers in the range of “0” to “F”.
As described above, in this embodiment, the random number generation cycles in the random number generator 309a for determining whether or not to accept and the initial value random number generator 309b are made different from each other.

In FIG. 4, the initialization processing unit 315 includes a gaming state determination unit 401, a reset unit 402, an initial value setting unit 403, and a reset determination unit 404.
When the power switch 219 is turned on and the supply of power from the power supply device 209 is started, the gaming state determination unit 401 determines the gaming state in the gaming machine 100 immediately before the supply of power from the power supply device 209 is cut off. While reading from the gaming state storage unit 314, the gaming state in the gaming machine 100 is acquired. Specifically, the gaming state determination unit 401, for example, the state of the flag stored in the flag storage unit 302, and the random number generation units 304a to 304f and 309a of the special symbol lottery unit 304 and the normal symbol lottery unit 309, for example. , 309b is obtained as the current gaming state in the gaming machine 100 (the gaming state in the gaming machine 100 immediately after the power from the power supply device 209 is turned on).
Here, the state of the flag stored in the flag storage unit 302 and the value of the random number generated in the special symbol lottery unit 304 and the normal symbol lottery unit 309 are used as the current gaming state of the gaming machine 100. Although acquired, the current gaming state of the gaming machine 100 acquired by the initialization processing unit 315 is not limited to this.

  As described above, the gaming state in the gaming machine 100 immediately before the power supply from the power supply device 209 is cut off and the current gaming state in the gaming machine 100 (the game immediately after the power from the power supply device 209 is turned on). Gaming state in the machine 100), the gaming state determination unit 401 determines whether or not those gaming states match. As a result of the determination, if the gaming state is consistent, the initial value setting unit 403 is generated by each of the random number generation units 304a to 304f, 309a, and 309b immediately before the supply of power from the power supply device 209 is interrupted, for example. The random number value, initial value, and the like are read from the gaming state storage unit 314, and the read value is set in the special symbol lottery unit 304 and the normal symbol lottery unit 309, so that the special symbol lottery unit 304 and the normal symbol lottery unit The random number generation operation in each of the random number generation units 304a to 304f, 309a, and 309b of the unit 309 is set to a state immediately before the supply of power from the power supply device 209 is interrupted. Then, the random number generators 304a to 304f, 309a, and 309b of the special symbol lottery unit 304 and the normal symbol lottery unit 309 start operation from the set state.

On the other hand, if the gaming state does not match, it is determined that there has been some change in the state of the gaming machine 100 after the supply of power from the power supply device 209 is interrupted until the power is turned on again. And the reset part 402 resets the memory content of RAM202c. At this time, information including at least the initial values of the random number generators 304a to 304f, 309a, and 309b is reset.
Then, the initial value setting unit 403 acquires (latches) the random number (current value) generated by the random number generator 220, and uses the acquired random number to special symbol lottery unit 304 and normal symbol lottery unit 309. The initial values of the random number generators 304a to 304f, 309a, and 309b are generated.

  Specifically, in the present embodiment, the initial value setting unit 403 uses the random numbers generated by the random number generator 220 to use the random numbers generators 304 a to 304 f and 309 a of the special symbol lottery unit 304 and the normal symbol lottery unit 309. , 309b, different values are generated as initial values. For example, the initial value setting unit 403 selects each bit to be read from a 16-bit random value signal generated by the random number generator 220, whereby each random number generation unit 304 a of the special symbol lottery unit 304 and the normal symbol lottery unit 309 is selected. Different values can be generated as initial values of .about.304f, 309a, and 309b. For example, the initial value setting unit 403 reads only even bits, reads only odd bits, reads high-order x bits, or low-order y bits of a 16-bit random value signal generated by the random number generator 220. Bits can be read out (x and y are natural numbers). Then, the initial value setting unit 403 can generate different values as the initial values of the random number generation units 304a to 304f, 309a, and 309b by calculating the read values.

  In this case, different values are generated as initial values of the random number generators 304a to 304f, 309a, and 309b of the special symbol lottery unit 304 and the normal symbol lottery unit 309. There is no. For example, at least two initial values of the random number generators 304a to 304f, 309a, and 309b of the special symbol lottery unit 304 and the normal symbol lottery unit 309 may be the same.

  The initial value setting unit 403 sets the initial values generated as described above as initial values of the random number generation units 304a to 304f, 309a, and 309b of the special symbol lottery unit 304 and the normal symbol lottery unit 309. Then, each of the random number generators 304a to 304f, 309a, and 309b of the special symbol lottery unit 304 and the normal symbol lottery unit 309 starts an operation based on the set initial value.

  The reset determination unit 404 determines whether or not the reset switch 223 has been operated to instruct to reset the storage contents of the RAM 201c in the main control board 201. When the reset determination unit 404 determines that the reset switch 223 has been operated (when it is determined that resetting of the storage content of the RAM 201c in the main control board 201 has been instructed), the reset unit 402 stores the storage content of the RAM 202c. Reset. At this time, information including at least the initial values of the random number generators 304a to 304f, 309a, and 309b is reset.

Then, as described above, the initial value setting unit 403 generates initial values of the random number generation units 304a to 304f, 309a, and 309b using the random numbers generated by the random number generator 220, and generates the generated initial values. The value is set in each of the random number generators 304a to 304f, 309a, and 309b. Then, each of the random number generators 304a to 304f, 309a, and 309b of the special symbol lottery unit 304 and the normal symbol lottery unit 309 starts an operation based on the set initial value.

  Next, an example of processing operations in the gaming machine 100 of the present embodiment configured as described above will be described with reference to the flowcharts of FIGS.

(Processing of main control board 201)
FIG. 6 is a main flowchart showing an example of processing operations in the main control board 201.
In step S1 of FIG. 6, the main control board 201 performs an initialization process. This initialization process is a process performed when the power switch 219 or the reset switch 223 is operated (turned on). Details of the initialization process will be described later with reference to FIG.

  Next, in step S2, the main control board 201 performs a game ball launch process. A specific example of this game ball launching process will be described. First, after the launch operation detection signal indicating that the launch handle 131 has been operated by the player is transmitted from the launch control board 205, the main control board 201, It is determined whether or not a certain amount of game balls are stored in the ball tray 128a.

  If the result of this determination is that a certain amount or more of game balls are not stored in the ball tray 128a, the main control board 201 transmits a launch permission signal to the launch control board 205 and the game balls are directed to the game area 115. An effect command indicating that the command has been fired is generated and transmitted to the sub-control board 202. Thereby, a game ball is launched into the game area 115 and an effect during the game is started.

  On the other hand, when a certain amount or more of game balls are stored in the ball tray 128a, the main control board 201 transmits a launch non-permission signal to the launch control board 205, and the game balls cannot be launched into the game area 115. An effect command indicating this is generated and transmitted to the sub-control board 202. In this case, even if the player operates the launch handle 131, the game ball is not fired toward the game area 115. In addition, the player is notified by turning on the illumination part 130 that a certain amount or more of the game balls are stored in the ball tray 128a.

  Next, in step S3, the main control board 201 performs a general winning process. This general winning process is a process performed when a game ball launched into the game area 115 wins the general winning opening 111. Details of the general winning process will be described later with reference to FIG.

  Next, in step S4, the main control board 201 performs normal symbol operation gate passage processing. This normal symbol operation gate passing process is a process performed when a game ball launched into the game area 115 passes through the normal symbol operation gate. The normal symbol operation gate passing process will be described later with reference to FIGS. 9-1 and 9-2.

  Next, in step S5, the main control board 201 performs a start winning process. This start winning process is a process performed when a game ball launched into the game area 115 wins the start winning port 112. Details of the start winning process will be described later with reference to FIGS. 10-1 and 10-2.

  Next, in step S6, the main control board 201 performs a special game execution process. This special game execution process is a process that is performed when a predetermined symbol is stopped and displayed on the special symbol display device 106 and the decorative symbol display device 107 to become a “hit” and the game shifts to a special game. Details of the special game execution process will be described later with reference to FIG.

  As described above, the main control board 201 repeatedly performs the initialization process, the game ball launch process, the general winning process, the normal symbol operation gate passing process, the start winning process, and the special game execution process. As shown in FIG. 11, in the present embodiment, each process is repeatedly executed while omitting unnecessary processes according to the state of the game.

(Initialization process)

As a result of this determination, if the power switch 219 is not turned on and the supply of power from the power supply device (main power supply) 209 has not started, the process proceeds to step S130 described later.

  On the other hand, when the power switch 219 is turned on and the supply of power from the power supply device 209 is started, the process proceeds to step S122. In step S <b> 122, the gaming state determination unit 401 reads the gaming state in the gaming machine 100 immediately before the power supply from the power supply device 209 is cut off from the gaming state storage unit 314.

  Next, in step S123, the gaming state determination unit 401 determines the current state of the flag stored in the flag storage unit 302, the random number generation units 304a to 304f of the special symbol lottery unit 304 and the normal symbol lottery unit 309, The current value of the random number generated in 309a and 309b is acquired as the current gaming state in the gaming machine 100 (the gaming state in the gaming machine 100 immediately after the power from the power supply device 209 is turned on).

  Next, in step S124, the gaming state determination unit 401 reads the “gaming state in the gaming machine 100 immediately before the supply of power from the power supply device 209” read out in step S122 and the “power source acquired in step S123”. It is determined whether or not the “gaming state in the gaming machine 100 immediately after the power from the device 209 is turned on” matches. As a result of the determination, if the gaming state matches, the process proceeds to step S125.

  In step S125, the initial value setting unit 403 displays the random number values and initial values generated by the random number generation units 304a to 304f, 309a, and 309b immediately before the power supply from the power supply device 209 is cut off. The random number generation operation in each of the random number generation units 304a to 304f, 309a, and 309b is set to a state immediately before the power supply from the power supply device 209 is cut off using the read information read from the gaming state storage unit 314. . Thereby, each random number generation part 304a-304f, 309a, 309b starts operation | movement from the set state. Then, the process returns to the main flowchart shown in FIG.

On the other hand, if the gaming state does not match, it is determined that there has been some change in the gaming machine 100 after the supply of power from the power supply device 209 is cut off until the power is turned on again, and step S126. Proceed to In step S126, the reset unit 402 resets the stored contents of the RAM 202c.
Next, in step S127, the initial value setting unit 403 acquires the random number (current value) generated by the random number generator 220.

  Next, in step S128, the initial value setting unit 403 uses the random numbers acquired in step S127, initial values of the random number generation units 304a to 304f, 309a, and 309b of the special symbol lottery unit 304 and the normal symbol lottery unit 309. Is generated. As described above, the initial value setting unit 403, for example, the initial value setting unit 403 reads predetermined bits out of the bits constituting the random value signal generated by the random number generator 220, and sets the read bits. By calculating, initial values of the random number generators 304a to 304f, 309a, and 309b can be generated.

  Next, in step S129, the initial value setting unit 403 uses the initial value generated in step S128 as initial values of the random number generation units 304a to 304f, 309a, and 309b of the special symbol lottery unit 304 and the normal symbol lottery unit 309. Set. Then, the random number generators 304a to 304f, 309a, and 309b of the special symbol lottery unit 304 and the normal symbol lottery unit 309 start operation from the set initial values. Then, the process returns to the main flowchart shown in FIG.

In step S121, when the power switch 219 is not turned on and power supply from the power supply device (main power supply) 209 is not started, power from the power supply device (main power supply) 209 is being supplied. Proceed to step S130.
In step S <b> 130, the reset determination unit 404 determines whether or not the reset switch 223 has been operated to instruct resetting of the storage contents of the RAM 201 c in the main control board 201.

If the result of this determination is that the reset switch 223 has not been operated and the reset of the stored contents of the RAM 201c in the main control board 201 has not been instructed, the process returns to the main flowchart shown in FIG.
On the other hand, when the reset switch 223 is operated to instruct resetting of the stored contents of the RAM 201c in the main control board 201, the process proceeds to step S131.
In step S131, the reset unit 402 resets the stored contents of the RAM 202c.
Next, in step S <b> 132, the initial value setting unit 403 acquires a random number (current value) generated by the random number generator 220.

  Next, in step S133, the initial value setting unit 403 uses the random numbers acquired in step S132, and the initial values of the random number generation units 304a to 304f, 309a, and 309b of the special symbol lottery unit 304 and the normal symbol lottery unit 309. Is generated. As described above, the initial value setting unit 403, for example, the initial value setting unit 403 reads predetermined bits out of the bits constituting the random value signal generated by the random number generator 220, and sets the read bits. By calculating, initial values of the random number generators 304a to 304f, 309a, and 309b can be generated.

Next, in step S134, the initial value setting unit 403 uses the initial value generated in step S133 as initial values of the random number generators 304a to 304f, 309a, and 309b of the special symbol lottery unit 304 and the normal symbol lottery unit 309. Set. Then, the random number generators 304a to 304f, 309a, and 309b of the special symbol lottery unit 304 and the normal symbol lottery unit 309 start operation from the set initial values. Then, the process returns to the main flowchart shown in FIG.
(General winning process)
Next, the details of the general winning process in step S3 of FIG. 6 will be described with reference to the flowchart of FIG.
In step S <b> 11 of FIG. 8, the winning determination unit 301 determines whether or not the gaming ball has won the general winning opening 111 based on the gaming ball passage signal transmitted from the winning opening board 203. If the result of this determination is that the game ball has won the general winning opening 111, the process proceeds to step S12, where the payout instruction unit 303 pays out the award ball number signal indicating that the number of winning balls is “4”. Transmit to the substrate 206. As a result, four prize balls are paid out to the ball tray 128a. In addition, the effect command generation unit 313 generates an effect command indicating that the general winning opening 111 has been won and transmits the effect command to the sub control board 202. Thereby, the sub-control board 202 informs the player that the general winning opening 111 has been won by, for example, lighting the electric decoration part 130. Then, the process returns to the main flowchart shown in FIG.
On the other hand, when the game ball has not won the general winning opening 111, it is not necessary to perform the process of step S12, and the process returns to the main flowchart shown in FIG.

(Normal symbol operation gate passing processing)
Next, the details of the normal symbol operation gate passing process in step S4 of FIG. 6 will be described with reference to the flowcharts of FIGS. 9-1 and 9-2.
In step S <b> 21 of FIG. 9A, the winning determination unit 301 determines whether or not the gaming ball has passed the normal symbol operation gate 103 based on the gaming ball passage signal transmitted from the winning opening board 203. If the result of this determination is that the game ball has passed through the normal symbol operation gate 103, the routine proceeds to step S22, where the normal symbol lottery unit 309 generates a random number and performs lottery (that is, obtains a random number). As described above, the success / failure determination random number generation unit 309a generates random numbers in ascending order, for example, by +1 from the initial value, and generates all the possible random numbers. Then, the random number generated by the initial value random number generation unit 309b The initial value is updated, and random numbers are generated in ascending order by +1 again from the updated initial value.

  As described above, when the power switch 219 or the reset switch 223 is operated and the stored contents of the RAM 201c are reset, the initial value generated by the initialization processing unit 315 (initial value setting unit 403) is determined to be true or false. This is set as the initial value of the random number generator 309a and the initial value random number generator 309b. Then, the validity determination random number generation unit 309a and the initial value random number generation unit 309b generate random numbers in ascending order, for example, by +1 from the set initial value. When all the possible random numbers are generated, the validity determination random number generation unit 309a updates the initial value to the random number generated by the initial value random number generation unit 309b, and again generates random numbers in ascending order by +1.

  As described above, in the present embodiment, when the power switch 219 or the reset switch 223 is operated and the stored contents of the RAM 201c are reset, the random number generator 220 generates the initial value of the random number generator 309a for determination of success / failure. Set to a value that uses a random number. Therefore, it is possible not to predetermine an initial value set in the random number generator 309a for determining whether or not it is correct when the stored contents of the RAM 201c are reset. Therefore, it is possible to suppress the random number generated by the random number generator 309a for determination of validity from being illegally grasped as compared with the prior art.

  In the present embodiment, not only the validity determination random number generator 309 a but also the initial value of the initial value random number generator 309 b is set to a value using the random number generated by the random number generator 220. Therefore, it is possible to prevent the initial value set in the initial value random number generation unit 309b from being determined in advance when the stored contents of the RAM 201c are reset. Therefore, after the stored content of the RAM 201c is reset, when the validity determination random number generation unit 309a updates the initial value for the first time, the update value can be prevented from being determined in advance. Therefore, it is possible to more surely prevent the random numbers generated by the random number generator 309a for determination of validity from being illegally grasped.

  Next, in step S23, the normal symbol lottery unit 309 determines whether or not the normal symbol is being variably displayed. If the result of this determination is that the normal symbol is variably displayed, the process proceeds to step S24, where the normal symbol lottery unit 309 counts the number of random numbers stored in the normal symbol random number storage area provided in the RAM 201c. It is determined whether or not there are three or less. As a result of this determination, if the number of random numbers stored in the normal symbol random number storage area is three or less, the process proceeds to step S25, where the normal symbol lottery unit 309 determines the normal symbol lottery result (step S22). Is stored in the normal symbol random number storage area, and the process returns to the main flowchart shown in FIG.

  If it is determined in step S24 that the number of random numbers stored in the normal symbol random number storage area exceeds three, the random number acquired in step S22 may be suspended. Since the normal symbol based cannot be displayed, the process returns to the main flowchart shown in FIG.

  On the other hand, if it is determined in step S23 that the normal symbol is not variably displayed, the process proceeds to step S26, where the normal symbol lottery unit 309 determines whether or not a random number is stored in the normal symbol random number storage area. judge. As a result of this determination, if random numbers are stored, the process proceeds to step S27, and the normal symbol lottery unit 309 determines whether the number of random numbers stored in the normal symbol random number storage area is three or less. Determine whether.

As a result of this determination, if the number of random numbers stored in the normal symbol random number storage area is three or less, the process proceeds to step S28, where the normal symbol lottery unit 309 determines the normal symbol lottery result (step S22). Is stored in the normal symbol random number storage area.
Next, in step S29, the normal symbol lottery unit 309 reads the random number stored earliest in the normal symbol random number storage area, and proceeds to step S30.

On the other hand, if it is determined in step S26 that no random number is stored, steps S27 to S29 are omitted and the process proceeds to step S30.
If it is determined in step S27 that the number of random numbers stored in the normal symbol random number storage area exceeds three, the random number acquired in step S22 may be suspended. Since the normal symbol based cannot be displayed, the process returns to the main flowchart shown in FIG.

When the normal symbol lottery result (random number) is obtained as described above, the process proceeds to step S30, and the normal symbol lottery unit 309 outputs the obtained random number to the winning determination unit 310.
Next, in step S31, the winning determination unit 310 refers to the flag storage unit 302 to determine whether or not the time reduction flag or the probability variation flag is turned on. As a result of the determination, if the time reduction flag or the probability change flag is turned on, it is determined that the operation is shifted to the “time reduction mode” or “probability change mode”, and the process proceeds to step S32, where the winning determination unit 310 determines that “ The default lottery table used in the case of the “short time mode” or “probability change mode” is read.
On the other hand, if it is determined that neither the time reduction flag nor the probability variation flag is turned on, it is determined that the mode is “normal mode”, and the process proceeds to step S33, where the winning determination unit 310 is “normal mode”. Extract the default lottery table used for.

  As described above, when the lottery table is selected in step S33, the process proceeds to step S34 in FIG. 9-2, and the winning determination unit 310 receives the lottery result (random number) output from the normal symbol lottery unit 309 in step S30. It is determined whether or not the selected lottery table corresponds to “winning”. That is, it is determined whether or not the normal symbol lottery is won.

  As a result of this determination, if the normal symbol lottery is won, the process proceeds to step S35, and the normal symbol display instruction unit 311 and the ordinary electric accessory driving instruction unit 312 refer to the flag storage unit 302 and the time flag is set. Determine whether it is turned on. Further, the normal symbol display instructing unit 311 and the ordinary electric accessory driving instructing unit 312 refer to the flag storage unit 302 to determine whether or not the probability variation flag is turned on. That is, it is determined whether or not a transition is made to either the “time reduction mode” or the “probability change mode”. As a result of this determination, if the time reduction flag or the probability change flag is turned on and the mode is shifted to the “time reduction mode” or “probability change mode”, the process proceeds to step S36. In step S 36, when the transition to the “short time mode” is in progress, the normal symbol display instruction unit 311 displays the normal symbols in a variable manner during the default normal symbol fluctuation display time in the “short time mode”. A display pattern for stopping and displaying “7” indicating “win” is formed, and the normal symbol display instruction signal indicating the formed display pattern is transmitted to the LED drive board 204. As a result, the normal symbol display device 108 performs a display operation in accordance with the display pattern indicated in the normal symbol display instruction signal. In addition, the effect command generation unit 313 generates an effect command based on the determination results of steps S34 and S35 and transmits it to the sub-control board 202.

  On the other hand, when transitioning to the “probability change mode”, the normal symbol display instructing unit 311 displays the normal symbols in a variable manner during the default normal symbol change display time in the “probability change mode”, and then “wins”. A display pattern for stopping and displaying “7” indicating that the normal symbol is displayed, and the normal symbol display instruction signal indicating the formed display pattern is transmitted to the LED drive board 204. As a result, the normal symbol display device 108 performs a display operation in accordance with the display pattern indicated in the normal symbol display instruction signal. In addition, the effect command generation unit 313 generates an effect command based on the determination results of steps S34 and S35 and transmits it to the sub-control board 202.

  Next, in step S <b> 37, the ordinary electric accessory driving instruction unit 312 transmits the ordinary electric accessory release signal indicating the default operation mode in the “time reduction mode” or the “probability change mode” to the winning opening board 203. Thereby, the ordinary electric accessory 104 operates in the operation mode indicated by the ordinary electric accessory release signal. Then, the process returns to the main flowchart shown in FIG. The normal electric accessory release signal is transmitted after the normal symbol is stopped and displayed on the normal symbol display device 108.

  If it is determined in step S35 that neither the time reduction flag nor the probability variation flag is ON, the “normal mode” is set, and the process proceeds to step S38, where the normal symbol display instruction unit 311 is in the “normal mode”. After the normal symbol is displayed in a variable manner during the default normal symbol variation display time, a display pattern is formed so that “7” indicating “win” is stopped and displayed, and the normal pattern indicating the formed display pattern is displayed. A symbol display instruction signal is transmitted to the LED drive board 204. As a result, the normal symbol display device 108 performs a display operation in accordance with the display pattern indicated in the normal symbol display instruction signal. In addition, the effect command generation unit 313 generates an effect command based on the determination results of steps S34 and S35 and transmits it to the sub-control board 202.

  Next, in step S <b> 39, the ordinary electric accessory driving instruction unit 312 transmits the ordinary electric accessory release signal indicating the default operation mode in the “normal mode” to the prize opening board 203. Thereby, the ordinary electric accessory 104 operates in the operation mode indicated by the ordinary electric accessory release signal. Then, the process returns to the main flowchart shown in FIG. The normal electric accessory release signal is transmitted after the normal symbol is stopped and displayed on the normal symbol display device 108.

  If it is determined in step S34 that the normal symbol lottery is not won, the process proceeds to step S40, and the normal symbol display instruction unit 311 refers to the flag storage unit 302 to determine whether or not the hourly flag is turned on. Determine whether or not. Further, the normal symbol display instruction unit 311 refers to the flag storage unit 302 to determine whether or not the probability variation flag is turned on. As a result of these determinations, if the time reduction flag or the probability change flag is turned on and the mode is shifted to the “time reduction mode” or “probability change mode”, the process proceeds to step S41, and the normal symbol display instruction unit 311 During the default normal symbol fluctuation display time in “mode” or “probability change mode”, after the normal symbol is variably displayed, a display pattern is formed so that “−” indicating “losing” is stopped and displayed. The normal symbol display instruction signal indicating the formed display pattern is transmitted to the LED drive board 204. As a result, the normal symbol display device 108 performs a display operation in accordance with the display pattern indicated in the normal symbol display instruction signal. In addition, the effect command generation unit 313 generates an effect command based on the determination results of steps S34 and S40 and transmits it to the sub-control board 202. Then, the process returns to the main flowchart shown in FIG.

  If it is determined in step S40 that neither the time reduction flag nor the probability variation flag is on, the “normal mode” is set, and therefore the process proceeds to step S42, where the normal symbol display instruction unit 311 displays the default in the “normal mode”. After the normal symbol is variably displayed during the normal symbol variation display time, a display pattern is formed so that “−” indicating “losing” is stopped and displayed, and the normal symbol display showing the formed display pattern An instruction signal is transmitted to the LED drive board 204. As a result, the normal symbol display device 108 performs a display operation in accordance with the display pattern indicated in the normal symbol display instruction signal. In addition, the effect command generation unit 313 generates an effect command based on the determination results of steps S34 and S40 and transmits it to the sub-control board 202. Then, the process returns to the main flowchart shown in FIG.

  If it is determined in step S21 of FIG. 9-1 that the game ball has not passed through the normal symbol operation gate 103, the process proceeds to step S43, and the normal symbol lottery unit 309 is provided in the RAM 201c. It is determined whether or not random numbers are stored in the normal symbol random number storage area. If a random number is stored as a result of this determination, the process proceeds to step S44. In step S44, the normal symbol lottery unit 309 determines whether or not the normal symbol is in a variable display. If the result of this determination is that the normal symbol is not being variably displayed, the process proceeds to step S29 described above. On the other hand, when the normal symbol is in a variable display, the process returns to the main flowchart shown in FIG.

(Start-up winning process)
Next, details of the start winning process in step S5 of FIG. 6 will be described with reference to the flowcharts of FIGS. 10-1 and 10-2.
In step S <b> 61 of FIG. 10A, the winning determination unit 301 determines whether or not the game ball has passed through the start winning port 112 based on the game ball passing signal transmitted from the winning port substrate 203. If the result of this determination is that the game ball has passed through the start winning opening 112, the process proceeds to step S62, where the special symbol lottery unit 304 generates a random number and performs lottery (that is, acquisition of a random number related to whether the special symbol is successful). I do). At the same time, the special symbol lottery unit 304 acquires a random number for determining a special symbol and a random number for determining a special symbol variation pattern. As described above, three random numbers including a random number relating to whether or not a special symbol is appropriate, a random number for determining a special symbol, and a random number for determining a special symbol variation pattern are referred to as “a set of random numbers”.

  As described above, the random number generation unit 304a for determining whether or not is correct generates random numbers in ascending order, for example, by +1 from the initial value, and generates all the possible random numbers. Then, the random number generated by the initial value random number generation unit 304d The initial value is updated, and random numbers are generated again in ascending order by +1. Further, the stop symbol determination random number generation unit 304b uses the random number generated by the initial value random number generation unit 304e as an initial value, for example, generates a random number in ascending order by +1 and generates all possible random numbers. The initial value is updated to the random number generated by the random number generator 304e, and the random number is generated again in ascending order by +1. Furthermore, the random time generation unit 304c for determining the variation time uses the random number generated by the initial value random number generation unit 304f as an initial value, for example, generates a random number in ascending order by +1, and generates all possible random numbers. The initial value is updated to the random number generated by the random number generation unit 304f, and the random number is generated again in ascending order by +1.

  As described above, when the power switch 219 or the reset switch 223 is operated and the stored contents of the RAM 201c are reset, the initial value generated by the initialization processing unit 315 (initial value setting unit 403) is changed to each random number. The initial values of the generating units 304a to 304c and the initial value random number generating units 304d to 304f are set. Then, each of the random number generators 304a to 304c and the initial value random number generators 304d to 304f generates random numbers in ascending order, for example, +1 from the set initial value. When each of the random number generators 304a to 304c generates all the random numbers that can be generated, the random number generators 304a to 304c update the initial values to the random numbers generated by the initial value random number generators 304d to 304f, and the random numbers are again incremented by +1 from the updated initial values. Is generated.

  As described above, in this embodiment, when the power switch 219 and the reset switch 223 are operated and the stored contents of the RAM 201c are reset, the random number generator 220 generates initial values of the random number generators 304a to 304c. Set to a value that uses a random number. Therefore, it is possible to prevent the initial values set in the random number generation units 304a to 304c from being determined in advance when the stored contents of the RAM 201c are reset. Therefore, it is possible to suppress the random number generated by each of the random number generation units 304a to 304c from being illegally grasped compared to the conventional case.

  In this embodiment, not only the random number generators 304 a to 304 c but also the initial values of the initial value random number generators 304 d to 304 f are set to values using the random numbers generated by the random number generator 220. Therefore, it is possible to prevent the initial values set in the initial value random number generators 304d to 304f from being determined in advance when the stored contents of the RAM 201c are reset. Accordingly, when the random number generators 304a to 304c update the initial values for the first time after the stored contents of the RAM 201c are reset, the update values can be prevented from being determined in advance. Accordingly, it is possible to more reliably suppress the random numbers generated by the random number generation units 304a to 304c from being illegally grasped.

  Next, in step S63, the special symbol lottery unit 304 refers to the flag storage unit 302 and determines whether or not the bonus flag is turned off. If the result of this determination is that the bonus flag has been turned off, the process proceeds to step S64, and the special symbol lottery section 304 determines whether or not the special symbol is being variably displayed. If the result of this determination is that the special symbol is variably displayed, the process proceeds to step S65, where the special symbol lottery section 304 stores “one set” stored in the special symbol random number storage area provided in the RAM 201c. It is determined whether or not the number of “random number” is three or less.

As a result of the determination, if the number of the set of random numbers stored in the special symbol random number storage area is three or less, the process proceeds to step S66, and the special symbol lottery unit 304 determines the special symbol lottery result. (The random number acquired in step S62) is stored in the special symbol random number storage area.
On the other hand, if it is determined in step S63 that the bonus flag is not turned off (turned on), the special game is being executed, and the process proceeds to step S65.
If it is determined in step S65 that the number of “one set of random numbers” stored in the special symbol random number storage area exceeds three, the random numbers acquired in step S62 are suspended. However, since the special symbol based on the random number cannot be displayed, the process returns to the main flowchart shown in FIG.

  On the other hand, if it is determined in step S64 that the special symbol is not being variably displayed, the process proceeds to step S67, and the special symbol lottery unit 304 stores “one set of random numbers” in the special symbol random number storage area. It is determined whether or not. As a result of this determination, if “a set of random numbers” is stored, the process proceeds to step S68, where the special symbol lottery unit 304 stores “a set of random numbers” stored in the special symbol random number storage area. It is determined whether the number of is less than or equal to three.

If the number of “one set of random numbers” stored in the special symbol random number storage area is three or less as a result of this determination, the process proceeds to step S69, where the special symbol lottery section 304 The lottery result (“one set of random numbers” acquired in step S62) is stored in the special symbol random number storage area.
Next, in step S70, the special symbol lottery unit 304 reads the “one set of random numbers” stored earliest in the special symbol random number storage area, and proceeds to step S71.

On the other hand, if it is determined in step S67 that the "one set of random numbers" is not stored, steps S68 to S70 are omitted and the process proceeds to step S71.
In step S68, if it is determined that the number of “one set of random numbers” stored in the special symbol random number storage area exceeds three, the “one set of random numbers” acquired in step S62. ”Cannot be held, nor can the special symbol based on the“ one set of random numbers ”be displayed, and the process returns to the main flowchart shown in FIG.

When the lottery result (random number) of the special symbol is obtained as described above, the process proceeds to step S71, and the special symbol lottery unit 304 outputs the obtained “one set of random numbers” to the winning determination unit 305.
Next, in step S72, the winning determination unit 305 refers to the flag storage unit 302 to determine whether or not the probability variation flag is turned on. If the result of this determination is that the probability variation flag is on, it is determined that the mode has been shifted to the “probability variation mode”, and the process proceeds to step S73. The winning determination unit 305 is used when the probability variation mode is in effect. The default lottery table for probability variation is extracted.

  On the other hand, if the probability variation flag is not turned on, the process proceeds to step S74, and the winning determination unit 305 refers to the flag storage unit 302 to determine whether or not the time reduction flag is turned on. As a result of this determination, if the time reduction flag is turned on, it is determined that the mode is shifted to the “time reduction mode”, the process proceeds to step S75, and the winning determination unit 305 refers to the flag storage unit 302. Add 1 to the number of time reductions. That is, the number of games in the “short time mode” corresponding to the current game (the number of games in the “short time mode”) is counted. Then, the effect command generation unit 313 generates an effect command indicating the number of games in the “time saving mode” and transmits it to the sub-control board 202.

Next, in step S76, the winning determination unit 310 extracts the default normal lottery table to be used in the “time reduction mode”.
Next, in step S77, the winning determination unit 305 refers to the count value of the short-time operation counting unit 308 to determine whether or not the “short-time mode” has ended by digesting the prescribed number of games. If the result of this determination is that the prescribed number of games has been exhausted and the “time reduction mode” has ended, the process proceeds to step S78, and the winning determination unit 305 refers to the flag storage unit 302 and turns off the time reduction flag.

  If it is determined in step S77 that the prescribed number of games has not been consumed, the “time reduction mode” is ongoing, and the process in step S78 is omitted.

Further, if it is determined in step S74 that the time reduction flag is not turned on, since it is “normal mode”, the process proceeds to step S79, and the winning determination unit 305 uses the default normal mode used in “normal mode”. Extract the lottery table.
As described above, when the lottery table is extracted in steps S73, S76, and S79, the process proceeds to step S80 in FIG. 10-2, and the winning determination unit 305 outputs the lottery result output from the special symbol lottery unit 304 in step S71 ( It is determined whether or not the random number relating to whether or not the special symbol is true corresponds to “big hit” in the extracted lottery table. That is, it is determined whether or not a special symbol lottery is won.

  As a result of this determination, if the special symbol lottery is won, the process proceeds to step S81, and the winning determination unit 305 further determines whether to shift to the “probability change mode” or the “short time mode” after the special game. Referring to the flag storage unit 302, the bonus flag is turned on. At this time, if the probability variation flag is turned on, the winning determination unit 305 turns off the probability variation flag. Then, the process proceeds to step S82. On the other hand, if the special symbol lottery is not won, the process of step S81 is omitted and the process proceeds to step S82.

  In step S82, the special symbol display instruction unit 306 refers to the flag storage unit 302 and determines whether or not the time reduction flag or the probability change flag is turned on. As a result of the determination, if the time reduction flag or the probability variation flag is turned on, since either the “time reduction mode” or the “probability variation mode” is being executed, the process proceeds to step S83. The special symbol display instruction unit 306 forms a display pattern for the time reduction / probability change mode based on the determination results in steps S80 and S82, and sends the special symbol display instruction signal indicating the formed display pattern to the LED drive board 204. Send. As a result, the special symbol display device 106 performs a display operation according to the display pattern indicated by the special symbol display instruction signal.

  On the other hand, when the time reduction flag or the probability variation flag is not turned on, since it is “normal mode”, the process proceeds to step S84, and the special symbol display instruction unit 306 determines that “normal A display pattern for “mode” is formed, and the special symbol display instruction signal indicating the formed display pattern is transmitted to the LED drive board 204. Thereby, the special symbol display device 106 performs a display operation according to the display pattern indicated in the special symbol display instruction signal.

In step S85, the effect command generation unit 313 generates an effect command according to the current game state based on the determination results in steps S80 and S82, and transmits the effect command to the sub control board 202.
Next, in step S86, the special symbol display device 106 displays the special symbol to be stopped after the variable symbol is displayed. Also, the payout instruction unit 303 transmits the prize ball number signal indicating that the prize ball number is “4” to the payout control board 206. As a result, four prize balls are paid out to the ball tray 128a.

  Next, in step S87, the winning determination unit 305 refers to the flag storage unit 302 to determine whether or not the bonus flag is turned on. If the result of this determination is that the bonus flag is on, the process proceeds to step S88, where the winning determination unit 305 displays a special symbol (so-called probability variation symbol) indicating the transition to the “probability variation mode” as a special symbol display device 106. It is determined whether or not the display is stopped.

  As a result of the determination, if the probability variation symbol is stopped and displayed on the special symbol display device 106, the process proceeds to step S89, and the winning determination unit 305 refers to the flag storage unit 302 and turns on the probability variation flag. In addition, after executing the special game, the effect command generation unit 313 generates an effect command indicating that the mode changes to the probability change mode, and transmits it to the sub-control board 202. As a result, the decorative symbol display device 107 displays on the decorative symbol display device 107 the fact that it shifts to the probability changing mode after executing the special game. Then, the process returns to the main flowchart shown in FIG.

  On the other hand, if the probability variation symbol is not stopped and displayed, the process proceeds to the “time reduction mode”, and thus the process proceeds to step S90, where the winning determination unit 305 refers to the flag storage unit 302 and turns on the time reduction flag. In addition, after executing the special game, the effect command generation unit 313 generates an effect command indicating that the mode is shifted to the time reduction mode, and transmits the effect command to the sub control board 202. As a result, the decorative symbol display device 107 displays on the decorative symbol display device 107 that the mode is shifted to the time-saving mode after executing the special game. Then, the process returns to the main flowchart shown in FIG.

When it is determined in step S61 of FIG. 10-1 that the game ball has not passed through the start winning opening 112, the process proceeds to step S91, and the special symbol lottery unit 304 is provided in the RAM 201c. It is determined whether or not random numbers are stored in the special symbol random number storage area. If the result of this determination is that random numbers are stored, the process proceeds to step S92. Then, the special symbol lottery unit 304 determines whether or not the special symbol is being variably displayed. If the result of this determination is that the special symbol is not being variably displayed, the process proceeds to step S70 described above.
On the other hand, in the case where no random number is stored in step S91 and in the case where it is determined in step S92 that the special symbol is being variably displayed, it is not necessary to perform the processing after step S62. Return to the main flowchart.

(Special game execution process)
Next, the details of the special game execution process in step S6 of FIG. 6 will be described with reference to the flowchart of FIG.
In step S101 of FIG. 11, the winning determination unit 305 refers to the flag storage unit 302 and determines whether or not the bonus flag is turned on. If the result of this determination is that the bonus flag is not turned on, there is no need to perform the processing after step S102 (since it does not shift to a special game), the process proceeds to the main flowchart shown in FIG.

On the other hand, if the bonus flag is on, the process proceeds to step S102. In step S <b> 102, the special winning opening release instruction unit 307 transmits the special winning opening opening instruction signal to the winning opening board 203. As a result, the special winning opening 113 is opened, and one round (unit game) of the 15 special games is started.
Next, in step S <b> 103, the winning determination unit 301 determines whether or not the game ball has passed through the big winning opening 113 based on the gaming ball passing signal transmitted from the winning opening board 203.

  If the result of this determination is that the game ball has passed through the big winning opening 113, the process proceeds to step S104, where the winning determination section 301 determines that the game ball is based on the gaming ball passing signal transmitted from the winning opening board 203. It is determined whether or not the specific area 121 has been passed. If the result of this determination is that the game ball has passed through the specific area 121, the process proceeds to step S105, where the special winning opening opening instruction unit 307 transmits the specific area control instruction signal to the winning opening board 203 and proceeds to step S106. move on. As a result, the state in which the game ball can easily pass through the specific area 121 is released. On the other hand, if the game ball has not passed through the specific area 121, the process skips step S105 and proceeds to step S106.

  Next, in step S <b> 106, the effect command generation unit 313 generates an effect command indicating that the game ball has passed through the big prize opening 113 or the specific area 121, and transmits it to the sub control board 202. As a result, an image indicating that the game ball has passed through the special winning opening 113 or the specific area 121 is displayed on the decorative symbol display device 107. Also, the payout instruction unit 303 transmits the prize ball number signal indicating that the prize ball number is “15” to the payout control board 206. Thereby, 15 prize balls are paid out to the ball tray 128a.

  If it is determined in step S103 that the game ball has not won the grand prize opening 113, the processing of steps S104 to S106 is omitted and the process proceeds to step S107.

  Next, in step S107, the special winning opening release instruction unit 307 determines whether or not a predetermined time (29.5 seconds) has elapsed since the special winning opening 113 is opened. As a result of the determination, if the predetermined time has elapsed, it is the end of the unit game, so the process proceeds to step S108, and the special winning opening release instruction unit 307 transmits a special winning opening closing signal to the winning opening board 203. To do. As a result, the special winning opening 113 is closed.

Next, in step S <b> 109, the special winning opening release instruction unit 307 determines whether or not the state where it is easy to pass the game ball to the specific area 121 is released. As a result of the determination, when the state where the passing of the game ball to the specific area 121 is released is released, the process proceeds to step S110, where the special winning opening release instructing unit 307 displays all unit games in the special game (that is, It is determined whether or not (special game) has ended. If the result of this determination is that the special game has ended, the process proceeds to step S111, where the effect command generating unit 313 generates an effect command indicating the end of the special game and transmits it to the sub control board 202. As a result, a video indicating the end of the special game is displayed on the decorative symbol display device 107. Further, the special winning opening opening instruction unit 307 transmits the specific area control instruction signal to the winning opening board 203. As a result, the game ball can easily pass through the specific area 121.
In step S112, the winning determination unit 305 refers to the flag storage unit 302, turns off the bonus flag, and returns to the main flowchart shown in FIG.

  In step S107, when it is determined that the predetermined time has not elapsed since the big winning opening 113 is opened, the process proceeds to step S113, and the big winning opening releasing instruction unit 307 transmits the above-mentioned winning determination unit 301. Based on the game ball passing signal, it is determined whether or not 10 or more game balls have passed through the big prize opening 113. If the result of this determination is that there are 10 or more game balls that have passed through the special winning opening 113, it means that the unit game is over, so that the process proceeds to step S108, and the special winning opening 113 is closed.

On the other hand, if there are not ten or more game balls that have passed through the big winning opening 113, the unit game is continuing, and the process returns to the main flowchart shown in FIG.
If it is determined in step S110 that all unit games in the special game have not ended, the process proceeds to the next unit game. Therefore, the process proceeds to step S114, and the effect command generation unit 313 performs the next unit game. An effect command indicating that the process proceeds to is generated and transmitted to the sub-control board 202. As a result, a video indicating that the next unit game has progressed is displayed on the decorative symbol display device 107. Further, the special winning opening opening instruction unit 307 transmits the specific area control instruction signal to the winning opening board 203 and returns to the main flowchart shown in FIG. As a result, the game ball can easily pass through the specific area 121.
The contents of the effect command generated by the effect command generating unit 313 and the timing for transmitting the effect command are not limited to those shown in the flowcharts of FIGS.

  As described above, in the present embodiment, a hardware random number generator 220 that generates a random number from an initial value without updating the initial value, and a software random number generator that generates a random number from the initial value while updating the initial value The gaming machine 100 includes 304a to 304f, 309a, and 309b. The random number generator 220 is supplied with backup power from the auxiliary power supply 222 even when the power supply 209 as the main power supply is shut off. Thereby, even if the main power is turned off, the random number generator 220 continues to generate random numbers. Then, the values based on the random numbers generated by the random number generator 220 after the reset operation of the RAM 201c is performed as the initial values of the random number generators 304a to 304f, 309a, and 309b. Therefore, it is possible to prevent a predetermined value from being set as the initial value of the random number generators 304a to 304f, 309a, and 309b after the RAM 201c is reset. Therefore, it is possible to suppress that the random numbers generated by the random number generation units 304a to 304f, 309a, and 309b are illegally detected more than before, and to suppress unauthorized operations performed on the generated random numbers more than before. can do.

  As described above, the initial values of the initial value random number generators 304d to 304f and 309b as well as the success / failure determination random number generators 304a and 309a are set to values based on the random numbers generated by the random number generator 220. Thus, after the reset operation of the RAM 201c, when the first and second determination random number generation units 304a and 309a update the initial value for the first time, the update value can be prevented from being determined in advance. Therefore, it is possible to more reliably suppress the random number generated by the random number generators 304a, 309a, etc.

  In the present embodiment, the state of the gaming machine 100 (for example, the gaming state) immediately before the power supply device 209 that is the main power supply is shut off is retained even after the power supply device 209 is shut off using the auxiliary power supply 222. In addition, the state of the gaming machine immediately before the power supply device 209 is shut off (for example, the gaming state) is compared with the state of the gaming machine 100 when the power supply device 209 is turned on again (for example, the gaming state). If they do not match, it is determined that there has been any change in the gaming machine 100 between the time when the power supply device 209 is shut off and the time when it is turned on again, and the RAM 201c is reset. A value based on the random number generated by the random number generator 220 after the reset operation of the RAM 201c is set as the initial value of the random number generators 304a to 304f, 309a, and 309b. Therefore, after detecting that there has been some change in the state of the gaming machine 100 from when the power supply device 209 is shut off to when it is turned on again, the initial values of the random number generators 304a to 304f, 309a, 309b are set. , It can be changed to a value that is not predetermined.

On the other hand, when the state of the gaming machine immediately before the power supply device 209 is shut off (for example, the gaming state) and the state of the gaming machine 100 when the power supply device 209 is turned on again (for example, the gaming state), It is determined that there is no change in the gaming machine 100 between the time when the power supply device 209 is shut off and the power is turned on again, and the random number generators 304a to 304f, 309a, and 309b are in a state immediately before the power supply device 209 is shut off. Set the random number generation operation.
As described above, when the state of the gaming machine immediately before the power supply device 209 is cut off (for example, the gaming state) and the state of the gaming machine 100 when the power supply device 209 is turned on again (for example, the gaming state) Since the initial values of the random number generators 304a to 304f, 309a, and 309b are not set to the values based on the random number generated by the random number generator 220, the initial values of the random number generators 304a to 304f, 309a, and 309b are required. It is possible to prevent the change as described above, and it is possible to perform the initialization process of the gaming machine 100 more quickly.

  In this embodiment, when the reset switch 223 for forcibly resetting the RAM 201c is operated, the reset operation of the RAM 201c is forcibly performed, and the value based on the random number generated by the random number generator 220 is obtained. The initial values of the random number generators 304a to 304f, 309a, and 309b are set. Therefore, the initial values of the random number generators 304a to 304f, 309a, and 309b can be changed to values that are not predetermined according to the intention of the administrator of the gaming machine 100.

  In the present embodiment, since the initial values of the random number generators 304a to 304f, 309a, and 309b are generated based on the random number generated by the random number generator 220, the random number generators 304a to 304f, 309a, The initial value of 309b can be determined more flexibly.

  In the embodiment described above, the power from the auxiliary power supply device 222 is supplied not only to the random number generator 220 (random number control board 221) but also to the main control board 201 via the power receiving board 207. However, this is not always necessary. That is, the power from the auxiliary power supply 222 may be supplied only to the random number generator 220 (random number control board 221). As described above, it is sufficient that the power from the auxiliary power supply 222 is supplied to at least the random number generator 220 (random number control board 221).

  In the embodiment described above, the random number generator 220, the random number control board 221 and the main control board 201 are configured separately. However, this is not always necessary. That is, the random number generator 220 and the random number control board 221 may be included in the main control board 201. Even in this case, as described above, the power from the auxiliary power supply device 222 may be supplied only to the random number generator 220 (random number control board 221), not the entire main control board 201. it can. Further, the power from the auxiliary power supply 222 can be supplied to the entire main control board 201. Further, in this case, the random number control board 221 can be omitted.

  In this embodiment, the random number generator 220 generates initial values of random numbers related to whether or not a special symbol, random numbers for determining a special symbol, random numbers for determining a special symbol variation pattern, and random numbers related to whether or not a normal symbol is determined. However, the random number for setting the initial value using the random number generated by the random number generator 220 is not limited to these. For example, when a lottery to determine whether or not to shift to the “probability change mode” is also performed, the initial value of the random number related to the shift to the “probability change mode” is set using the random number generated by the random number generator 220. May be.

  In this embodiment, the random number generator 220 is a hardware random number generator, and the random number generators 304a to 304f, 309a, and 309b are software random number generators. However, this is not necessarily required. If the initial value of the random number generating means for updating the initial value is set using the random number generated by the random number generating means that does not update the initial value after the reset operation of the RAM 202c or the like, the random number generating means Or by software.

  Further, as described above, if the initial values of the initial value random number generators 304d to 304f and 309b are set to values based on the random numbers generated by the random number generator 220, the validity determination random number generator 304a. , 309a and the like, which is preferable because it is possible to more reliably suppress the random number generated by the 309a and the like. However, the initial values of the initial value random number generators 304d to 304f and 309b are not necessarily set to values based on the random numbers generated by the random number generator 220. For example, among the initial values of the initial value random number generators 304d to 304f and 309b, only the initial values of the initial value random number generators 302b and 309b for updating the initial values of the validity determination random number generators 304a and 309a are changed to random numbers. The value may be set based on a random number generated by the generator 220.

In the present embodiment, the random number generator 220 has only a function of generating random numbers for setting initial values of the random number generators 304a to 304f, 309a, and 309b. However, the random number generator 220 may have other functions. For example, the random number generator 220 may generate a random number that combines the random number for setting the initial values of the random number generators 304a to 304f, 309a, and 309b and the random number related to whether or not the special symbol is appropriate. That is, one random number generated by the random number generator 220 is used as a random number for setting initial values of the random number generators 304a to 304f, 309a, and 309b, or as a random number related to whether or not a special symbol is appropriate. Also good.
In this case, since the random number generator 220 generates a random number related to whether the special symbol is true or not, it is not always necessary to provide the random number generator 304a for determining whether or not the special symbol is generated.
Further, it may be determined whether or not the game is a “hit” by using both the random number generated by the random number generator 220 and the random number generated by the random number generator for determination of success / failure 304a.

Further, the range and cycle of random numbers generated by the random number generators 304a to 304f, 309a, and 309b are not limited to those described above. The range of random numbers generated by at least two of the random number generators 304a to 304f, 309a, and 309b may be the same, or at least two cycles of the random number generators 304a to 304f, 309a, and 309b may be the same. .
Further, even if the power supply device 209 that is the main power supply is shut off, the auxiliary power supply device 222 as shown in FIG. 2 is not necessarily used as long as power is supplied to the random number generator 220. . For example, a backup power source may be configured using a capacitor provided on the main control board 201.

  In the present embodiment, the first type pachinko machine has been described as an example, but the operation of the present embodiment can be applied to a pachinko machine other than the first type pachinko machine. Further, the present embodiment can be applied to a first-class pachinko machine of a type other than the first-class pachinko machine described in the present embodiment. For example, the present embodiment can be applied to a so-called fall type first-class pachinko machine.
