2. Description of the Related Art Normally, in a pachinko game machine, when a game ball that is launched on a game board by operating a firing handle enters a winning opening or a starting opening provided on the game board,
When the game balls are paid out in a predetermined payout number (for example, 5 balls), and further, when the game balls enter the starting opening, a so-called variable display game is started on the display device provided on the game board. To be done. This variable display game is a game imitating a game played in a slot machine, and a plurality of variable symbols are displayed on the display device, and after each of them is variably displayed, these symbols are sequentially stopped at a predetermined timing. It is a game in which a big hit state occurs when a combination of symbols when the stop display of all the symbols is confirmed is a predetermined combination.

Actually, a lottery for determining whether or not to generate a jackpot state when a game ball enters the starting opening is carried out, and the variable display game is stopped and displayed based on the result of the lottery. The combination of symbols to be determined is determined, and the determined combination of symbols is displayed on the display device.

When a big hit state occurs after the variable display game ends, a shutter provided in the vicinity of the big winning opening is operated to open the big winning opening, and thereafter, the big winning opening is opened. When a preset number of game balls (for example, 10 balls) has entered or a predetermined period has elapsed, the shutter is operated again to close the special winning opening. In such a jackpot state, the jackpot game in which the jackpot is opened and then closed once is a predetermined number of times (for example,
15 times) will be repeated. While this jackpot game is being played, a predetermined number of game balls are paid out according to the number of game balls that have been put into the special winning opening, so the player wins many game balls. can do.

By the way, such a pachinko gaming machine,
In order to prevent the player's shooting spirit from being extremely disturbed, and not to earn illegal profits on the side of the game store (so-called pachinko hall), the exit rate, that is, on the game board per unit time (1 hour) The ratio of the number of game balls paid out to the number of game balls launched in is within a predetermined range (for example, 30 to 3).
00%).

However, due to the design, even if the exit rate is within a predetermined range, due to the delicate positional relationship of the plurality of nails planted on the game board in the manufacturing process, the winning opening and the starting opening. The ease of entering the game ball into the game game may be different, and in such a case, there is variation in the discharge rate. Therefore, usually, the pachinko game machine is inspected for the rate of launch at a test site before being supplied to a game store.
In this way, by inspecting the pachinko gaming machine,
It is possible to provide a healthy game to a player, because a pachinko gaming machine that has an extremely high or low participation rate is not supplied to the game store.

However, such an inspection conveys the pachinko gaming machine to the test site, and actually continues playing the game at the test site for a predetermined time. For each pachinko gaming machine, the game launched on the game board. Since the result is obtained by measuring the number of balls, the number of game balls paid out, etc., the inspection is complicated and there is a problem that the inspection side is troublesome.

Further, the above-mentioned inspection may give unexpected results due to unpredictable disturbances such as shocks when transported to a test site, changes in temperature and humidity, inclination of the installation place, and the like. Therefore, a gaming machine maker that manufactures pachinko gaming machines must take great effort to prepare for the inspection.

Furthermore, since the plurality of nails planted on the game board can be adjusted in inclination and the like on the game shop side, even if the above-described inspection is performed, the game shop is operated. On the side, the exit rate can be adjusted to some extent. Therefore, depending on the intention of the game store side, there is a possibility that the ball launch rate of the pachinko gaming machine may be extremely increased or decreased, and if such an action is performed, it is sound to the player. There was a problem that it was difficult to provide such a game.

On the other hand, unlike the game method using the above-mentioned normal lottery method, when a game ball enters the starting opening, a lottery for determining whether or not to generate a jackpot (hereinafter referred to as the first lottery) When the number of game balls hit is exceeded and a predetermined number (for example, 10 balls) is hit, a lottery for determining whether to set the jackpot flag, that is, whether to generate a jackpot state (hereinafter, referred to as the second There is a game method in which lottery) is performed.

In such a game method, when the first lottery is won, the jackpot right A is won, and when the second lottery is won, the jackpot right generating right B is won. Then, if the right A exists when the right B occurs (the big hit flag is set), the big hit state occurs, and if the right A occurs while the big hit flag is set, the big hit state occurs.
A plurality of jackpot rights A can be stocked, and if there are a plurality of jackpot rights A when the jackpot flag is set, a jackpot state occurs for all of them.

Specifically, the first lottery is carried out when the game ball enters the starting opening, and it is determined whether or not the jackpot right A is generated. When the jackpot right A occurs, it is determined whether or not the jackpot flag based on the second lottery is set, and when the jackpot flag is set, the jackpot state occurs.

When the jackpot flag based on the second lottery is not set, the right A is stocked when the first lottery is won, and when the first lottery is won, the stock number of the right A is increased. To do. That is, when the big hit flag is not set and the first lottery is won, the stock number of the right A is added every time the winning is won.

When winning the second lottery, it is determined whether or not the jackpot right A based on the first lottery exists.
When the right A is stocked, a big hit state occurs according to all the stocked numbers.

According to the pachinko gaming machine using the above-mentioned gaming method, the time for playing the jackpot game is extended according to the total number of stocks of the right A at that time. Therefore, even if the number of game balls entering the starting opening is small, the player may be able to obtain a considerable amount of balls at a time as long as he or she has launched the game balls. You can enjoy the game with greater expectation than the pachinko machine that uses the lottery method.

However, in the gaming method using the two types of lottery results as described above, the stock number of the right A may increase indefinitely until the jackpot flag is set based on the second lottery. In such a case, when a jackpot situation occurs, a huge number of balls may be paid out, and it is possible that the specified ball launch rate far beyond the design may be exceeded. There is a problem in that it may be extremely agitated and it becomes difficult to provide a sound game to the player.

[Problems to be Solved by the Invention]

The present invention has been made in view of the above-mentioned problems, and an object thereof is to take a method such as omitting the inspection of the ball ejection rate and the like and allowing it to be performed only by an unannounced inspection. Another object of the present invention is to provide a gaming machine, a storage medium, and a server that are capable of reducing the burden of inspection and can provide a healthy game to the player.

[0019]

In order to achieve the above object, the present invention provides that the numerical value obtained by the calculating means falls within a predetermined range based on a predetermined upper limit value or lower limit value. When entering, it is characterized by changing the probability of winning the winning lottery.

More specifically, the present invention provides the following. (1) A jackpot lottery means for carrying out a jackpot lottery for determining whether or not to generate a jackpot, a means for measuring the number of inserted game media for obtaining the number of game media used in the game, and a game medium to be paid out A gaming machine comprising a payout game medium number measuring means for obtaining a number and a calculating means for calculating a numerical value relating to the number of game media from these numbers, and, in addition to the jackpot lottery means, a win is generated. The winning lottery means is provided with a winning lottery means for performing a winning lottery for deciding whether or not to make it, and the winning lottery means has a numerical value obtained by the calculating means within a predetermined range based on a predetermined upper limit value or lower limit value. In this case, the probability of winning the winning lottery is changed.

According to the invention of (1), for example, when the numerical value relating to the number of game media falls within a predetermined range based on the lower limit value, the probability of winning the winning lottery is increased to increase the number of games. Increase the chances of acquiring media,
This suppresses a decrease in the number of game media, and conversely, when the number related to the number of game media falls within a predetermined range based on the upper limit value, the probability of winning the winning lottery is reduced, thereby increasing the number of game media. It is possible to reduce the chances that the game can be acquired, and thereby suppress the increase of the game media. In this way, when the numerical value regarding the number of game media falls within a predetermined range based on the upper limit value or the lower limit value, the probability of winning the winning lottery is changed to adjust the number of game media to be paid out, In order to keep the numerical value related to the number within the range from the upper limit value to the lower limit value, it is possible to omit the inspection such as the ball exit rate performed at the test site.
It is possible to deal with it by only an unannounced inspection. Also, for example, in a pachinko gaming machine, even when the inclination of a plurality of nails planted on the gaming board is adjusted,
By adjusting the number of game balls to be paid out so that the numerical value related to the number of game media falls within the range from the upper limit value to the lower limit value, it rarely exceeds the upper limit value or falls below the lower limit value. Therefore, a healthy game can be provided to the player.

The present invention further provides the following. (2) In the gaming machine described in (1), the calculating means is a game medium used for a game from the numbers obtained by the input game medium number measuring means and the payout game medium number measuring means. And a difference between the number of paid-out game media and the number of paid-out game media.

According to the invention of (2), the difference between the number of game media used in the game and the number of paid-out game media can be obtained as a numerical value relating to the game media. Then, when the difference between the number of game media used for the game and the number of game media paid out is within a predetermined range based on the lower limit value, the probability of winning the winning lottery is increased. , Increase the chances of acquiring many game media,
This suppresses the decrease of the game media, and conversely, when the difference between the number of game media used in the game and the number of game media paid out is within a predetermined range based on the upper limit value, By reducing the probability of winning the winning lottery, it is possible to reduce the chances that a large number of game media can be acquired, and thus to suppress the increase of the game media. In this way, when the difference between the number of game media used in the game and the number of paid-out game media falls within the predetermined range based on the upper limit value or the lower limit value, the probability of winning the winning lottery To adjust the number of game media to be paid out so that the difference between the number of game media used for the game and the number of game media paid out falls within the range from the upper limit value to the lower limit value. Therefore, it is possible to omit the inspection of the ball exit rate and the like performed at the test site, and for example, it is possible to deal with only the spot inspection. Also, for example, in a pachinko gaming machine, even if the tilt of a plurality of nails planted on the gaming board is adjusted, it is used in the game by adjusting the number of gaming balls to be paid out. In order to keep the difference between the number of game media and the number of paid-out game media within the range from the upper limit value to the lower limit value, there is almost no possibility of exceeding the upper limit value or falling below the lower limit value. A healthy game can be provided to the player.

The present invention further provides the following. (3) In the gaming machine described in (1) above, the calculating means is a game medium used for a game from the numbers obtained by the input game medium number measuring means and the payout game medium number measuring means. The ratio of the number of paid-out game media to the number of is calculated.

According to the invention of (3), as a numerical value relating to the game medium, with respect to the number of game media used in the game,
The percentage of the number of game media paid out can be obtained.
Then, when the ratio of the number of paid-out game media to the number of game media used in the game falls within a predetermined range based on the lower limit value, by increasing the probability of winning the winning lottery, Increase the chances of acquiring a lot of game media, thereby suppressing the decrease of game media, and conversely
When the ratio of the number of paid-out game media to the number of game media used in the game falls within a predetermined range based on the upper limit value, the probability of winning the winning lottery is reduced to increase the number of games. Reduce the chances of getting media,
This can suppress an increase in game media. In this way, when the ratio of the number of paid-out game media to the number of game media used for the game falls within the predetermined range based on the upper limit value or the lower limit value, the probability of winning the winning lottery is determined. Adjust the number of game media paid out by changing,
In order to ensure that the ratio of the number of paid-out game media to the number of game media used in the game falls within the range from the upper limit value to the lower limit value, the inspection of the ball launch rate etc. performed at the test site is omitted. It is possible to deal with this, and for example, it is possible to deal with it only by the spot inspection. Also, for example,
In a pachinko machine, even if the tilt of multiple nails planted on the game board is adjusted, the number of game balls used for the game is adjusted by adjusting the number of game balls to be paid out. , So that the ratio of the number of paid-out game media falls within the range from the upper limit value to the lower limit value, it rarely exceeds the upper limit value or falls below the lower limit value, and A healthy game can be provided.

The present invention further provides the following. (4) It is provided on the game board, and when a game ball enters, a winning hole for paying out a predetermined number of game balls is determined, and whether or not a jackpot is generated by entering a game ball is determined. A jackpot lottery is provided and a starting opening is provided, and a launch game ball measuring means for obtaining the number of game balls that have been launched, and a payout game ball measuring means for obtaining the number of game balls that have been delivered, A gaming machine comprising a ball-out rate calculating means for calculating a ball-out rate from these numbers,
A display device for performing a variable display and a stop display of a normal symbol having identification information, and a normal symbol lottery means for performing a normal symbol lottery that defines a normal symbol to be stopped and displayed, and the starting opening is for the normal symbol lottery. Winning, in response to the stop display of the normal symbol in a predetermined symbol, it is in an open state, the ordinary symbol lottery means, the exit rate obtained by the exit rate calculation means, in advance, When approaching the upper limit value or the lower limit value set, it is characterized by changing the probability of winning the ordinary symbol lottery.

According to the invention of (4), for example, when the exit rate approaches the lower limit value, the probability of winning the ordinary symbol lottery is increased, thereby increasing the probability that the starting opening is opened and increasing the number. By increasing the chances of winning a game ball of this, by suppressing the decrease in the rate of departure, conversely, when the rate of exit approaches the upper limit, by reducing the probability of winning the ordinary symbol lottery It is possible to reduce the probability of being released and reduce the chances that a large number of game balls can be acquired, thereby suppressing the increase in the rate of ball launch. In this way, when the exit rate approaches the upper limit or the lower limit, the probability of winning in the ordinary symbol lottery is changed to adjust the number of game balls paid out per unit time, and the exit rate falls from the upper limit to the lower limit. In order to keep the value within the range up to the value, it is possible to omit the inspection of the ball exit rate or the like performed at the test site, and for example, it is possible to deal with only the spot inspection. In addition, even if the inclination of multiple nails planted on the game board is adjusted, the number of game balls paid out per unit time is adjusted so that the rate of discharge is from the upper limit to the lower limit. Since the value is kept within the range up to the value, the upper limit value is hardly exceeded or the lower limit value is not exceeded, and a sound game can be provided to the player.

The present invention further provides the following. (5) In the gaming machine described in (4) above, the ordinary symbol lottery means wins the ordinary symbol lottery when the exit rate falls within a predetermined range based on the upper limit value or the lower limit value. It is characterized by changing the probability.

According to the invention of (5), for example, when the exit rate falls within a predetermined range based on the lower limit value, the probability of winning the ordinary symbol lottery is increased to open the starting opening. The probability of winning a large number of game balls is increased by increasing the probability of playing, and this suppresses the decrease in the rate of departure, and conversely, when the rate of entry is within the predetermined range based on the upper limit, By reducing the probability of winning the symbol lottery, it is possible to reduce the probability of opening the starting port and reduce the chances that a large number of game balls can be acquired, thereby suppressing an increase in the rate of exit. In this way, when the exit rate falls within the predetermined range based on the upper limit value or the lower limit value, the probability of winning in the normal symbol lottery is changed to adjust the number of game balls paid out per unit time, In order to keep the sphere rate within the range from the upper limit value to the lower limit value, it becomes possible to omit the inspection of the sphere rate etc. performed at the test site,
For example, it is possible to deal with it by only an unannounced inspection. In addition, even if the inclination of multiple nails planted on the game board is adjusted, the number of game balls paid out per unit time is adjusted so that the rate of discharge is from the upper limit to the lower limit. Since the value is kept within the range up to the value, the upper limit value is hardly exceeded or the lower limit value is not exceeded, and a sound game can be provided to the player.

The present invention further provides the following. (6) In the gaming machine described in (4) above, the ordinary symbol lottery means, when the ball-out rate is within a predetermined range based on an upper limit value or a lower limit value, the ball-out rate and the above It is characterized in that, in association with the magnitude of the difference between the upper limit value and the lower limit value, the probability of winning the ordinary symbol lottery is changed stepwise.

According to the invention of (6), the upper limit value of the ball launch rate is 300%, and the predetermined range based on the upper limit value is 270 to 30.
0%, when the rate of departure is less than 270% and higher than the predetermined range based on the lower limit, when the probability of winning the ordinary symbol lottery (hereinafter also referred to as the winning probability) is 60%, for example, When the percentage goes into 270-280%, the above winning probability is reduced to 40%, and the throwing rate is 280-290%.
When entering, the winning probability is reduced to 15%, and when the exit rate is 290 to 300%, the winning probability is reduced to 5%. It is related to the difference between the exit rate and the upper limit. Thus, the probability of winning the ordinary symbol lottery can be changed stepwise. The same applies to the lower limit value. In this way, by changing the probability of winning the regular symbol lottery stepwise, it is possible to suppress the rapid change in the ball-out rate that accompanies a large change in the probability of winning the regular symbol lottery, and the ball-out rate. Can be reliably prevented from becoming extremely high or low.

The present invention further provides the following. (7) A computer-readable storage medium that stores a control program for displaying a moving image, a still image, or an image in which these images are appropriately combined in a terminal device at least according to a game situation of the gaming device, The program determines that a game ball image is included in the image when the game board image, the game ball image corresponding to the game ball, and the game ball image overlaps the image, and the game ball image of the predetermined number When the prize hole image to be paid out and the game ball image overlap with the image, it is determined that the game ball image is included in the image, and a jackpot lottery is performed to determine whether or not to generate a jackpot. While displaying the starting opening image, the terminal device, the launch game ball measuring means for obtaining the number of game balls that have been launched, the payout game ball for obtaining the number of game balls that have been delivered It is a program for functioning as a measuring means, and a rate of departure calculating means for calculating the rate of departure from these numbers, and a display device image in which the terminal device is subjected to variable display and stop display of normal symbols having identification information. While displaying, and functioning as a normal symbol lottery that performs a normal symbol lottery that determines the normal symbol that is stopped and displayed, the starting mouth image wins the above-mentioned ordinary symbol lottery, and the normal symbol is stopped and displayed in a predetermined symbol In response to this, the state becomes an open state, the ordinary symbol lottery means, when the ball-out rate obtained by the ball-out rate calculation means is close to a predetermined upper limit value or lower limit value, It is characterized in that it is configured to change the probability of winning the ordinary symbol lottery.

According to the invention of (7), for example, when the exit rate approaches the lower limit value, the probability of winning the ordinary symbol lottery is increased, thereby increasing the probability that the starting opening will be increased. By increasing the chances of winning a game ball of this, by suppressing the decrease in the rate of departure, conversely, when the rate of exit approaches the upper limit, by reducing the probability of winning the ordinary symbol lottery It is possible to reduce the probability of being released and reduce the chances that a large number of game balls can be acquired, thereby suppressing the increase in the rate of ball launch. In this way, when the payout rate approaches the upper limit value or the lower limit value, the probability of winning the ordinary symbol lottery is changed to adjust the number of game balls paid out per unit time, and the discharge rate is from the upper limit value. Since it falls within the range up to the lower limit value, it rarely exceeds the upper limit value or falls below the lower limit value, and it is possible to omit the inspection of the rate of departure and to play a healthy game for the player. It is possible to provide a storage medium capable of providing.

The present invention further provides the following. (8) A server that controls each terminal device to display at least an image showing the gaming state of the gaming machine, and the gaming board image, the gaming ball image corresponding to the gaming ball, and the gaming ball image overlap with the image. When the game ball image is included in the image, a winning opening image for paying out a predetermined number of game balls, and when the game ball image overlaps the image, It is judged that a game ball image has been entered in, and a starting hole image that causes a jackpot lottery to be decided whether or not to generate a jackpot is displayed, and the terminal is launched to obtain the number of game balls that have been launched. To the terminal device, a game ball measuring means, a payout game ball measuring means for obtaining the number of paid game balls, and a control functioning as a discharge rate calculating means for calculating a discharge rate from these numbers Done and On the terminal, while displaying the display device image in which the variable display and the stop display of the ordinary symbol having the identification information are displayed, the ordinary symbol lottery means for performing the ordinary symbol lottery that determines the ordinary symbol to be stopped is operated, and The starting mouth image is won in the above-mentioned ordinary symbol lottery, and in response to the ordinary symbol being stopped and displayed in a predetermined symbol, the state becomes an open state. The obtained exit rate is characterized in that the terminal device is controlled to change the probability of winning the ordinary symbol lottery when approaching a predetermined upper limit value or lower limit value.

According to the invention of (8), for example, when the exit rate approaches the lower limit value, the probability of winning the ordinary symbol lottery is increased, thereby increasing the probability that the starting port is opened and increasing the number. By increasing the chances of winning a game ball of this, by suppressing the decrease in the rate of departure, conversely, when the rate of exit approaches the upper limit, by reducing the probability of winning the ordinary symbol lottery It is possible to reduce the probability that the game is released and reduce the chances that a large number of game balls can be acquired, thereby suppressing an increase in the rate of ball launch. In this way, when the payout rate approaches the upper limit value or the lower limit value, the probability of winning the ordinary symbol lottery is changed to adjust the number of game balls paid out per unit time, and the discharge rate is from the upper limit value. Since it falls within the range up to the lower limit value, it rarely exceeds the upper limit value or falls below the lower limit value, and it is possible to omit the inspection of the rate of departure and to play a healthy game for the player. It is possible to provide a server capable of providing.

For example, the inserted medal passage detector installed in the medal take-in path through which the medals inserted into the medal insertion slot pass, and the control unit which receives the detection signal from the inserted medal passage detector are Functions as a measuring means. The inserted medal passage detector may be mechanical, or may be a transmissive or reflective optical sensor that detects passage of a medal with light. Also,
In the case where the pachi-slot gaming machine or the like has a credit function, a means or the like for transmitting a detection signal regarding the number of medals bet for playing one game from the credited medals to the control unit Also, the above-mentioned input game medium number measuring means is included.

The "number of game media to be paid out" refers to the number of game media to be paid out, for example, the number of medals actually paid out when an internal winning combination is won in a pachi-slot gaming machine or slot machine. If the pachi-slot gaming machine or the like has a credit function, the number of medals credited by the internal winning combination is included in the number of inserted game media.

The "payout game medium number measuring means" means a means for measuring the number of paid-out game media. For example, a medal is given to a player depending on a winning combination. The payout medal detector installed in the medal payout device for paying out the coins, the control unit for receiving the detection signal from the payout medal detector, and the like function as the payout game medium number measuring means. When the pachi-slot gaming machine or the like has a credit function, means for transmitting a detection signal regarding the number of credited medals to the control unit is also included in the payout gaming medium number measuring means.

In the case of the above-mentioned pachi-slot gaming machine, the "payout number" means a case where a winning combination is won in the RB gaming state,
The number of medals paid out when a small winning combination is won in the BB game state or the general game state. In the following description, the number of medals paid out by winning in the RB gaming state is also referred to as the number of winning payouts in the RB gaming state. Winning a small role in the general game state,
The same applies to winning small prizes in the BB game state.
These are the number of payouts for winning in the normal game state and the number of payouts for winning small prizes in the BB game state, respectively.

In the case of the pachinko game machine, it means the number of game balls to be paid out when the game balls enter the winning opening or the starting opening. The start opening may be set so that the game ball is paid out in response to the game ball being entered, or may be set not to be paid out. In the following description, the number of game balls to be paid out in response to the fact that one game ball has entered the winning opening,
Also called the number of payouts. Similarly, with respect to the special winning opening and the starting opening, the number of payouts of the special winning opening and the number of payment of the starting opening will be referred to respectively. The number of payouts of the winning holes, the number of payouts of the special winning holes and the number of payouts of the starting holes are not particularly limited, and all the numbers of payouts may be the same,
It may be different.

The "numerical value regarding the number of game media" is a numerical value determined based on the number of input game media or the number of payout game media described above. For example, the difference between the number of input game media and the number of payout game media is calculated. Examples thereof include a numerical value obtained and a numerical value obtained by calculating the ratio of the number of payout game media to the number of input game media. In addition, the numerical value regarding the number of game media includes the number of input game media and the number of payout game media. This is because the number of input game media and the number of payout game media are information that is a basis for calculating a numerical value relating to the number of game media and are closely related. Hereinafter, as numerical values regarding the number of game media, a numerical value obtained by calculating the difference between the number of input game media and the number of payout game media and a numerical value obtained by calculating the ratio of the number of payout game media to the number of input game media will be described. In the invention, the numerical values regarding the number of game media are not limited to these numerical values. For example,
Other numerical values that can be calculated based on the number of inserted game media and the number of paid-out game media (specifically, the number of games in a pachi-slot gaming machine, etc.) can also be referred to as numerical values relating to the number of game media. As described above, the numerical value regarding the number of the above-mentioned game media includes the above-mentioned number of inserted game media and the number of paid-out game media, and other numerical values (the number of games in the pachislot gaming machine, etc.) This is because it is a numerical value that can be calculated based on the number of payout game media.

The "numerical value obtained by calculating the difference between the number of inserted game media and the number of paid out game media" is, for example, with respect to the number of medals inserted per unit number of games (for example, 100 games) in the above-mentioned pachi-slot gaming machine. This refers to the difference in the number of paid-out medals, and in the present specification, the above numerical value is also referred to as the difference number.

Here, when the number of inserted medals per unit number of games (100 games) is D (sheets) and the number of paid-out medals is E (sheets), the difference W (sheets) is as follows. It can be calculated using the equation (1). W = ED (1) The number of medals thrown in per unit game D
Can be always kept below a predetermined number by setting the maximum number of medals that can be used in one game to a predetermined number (for example, 3).

When the payout number of prizes in the RB gaming state is F (sheets) and the number of winnings is G (times), the number of medals to be paid out in the RB gaming state is F × G (sheets).
Becomes In addition, the payout number of small winning combinations in the BB gaming state is H (sheets), the number of small winning combinations is I (times), and
L during the BB game state, the number of times to shift to the RB game state
In the case of (times), the number of medals to be paid out in the BB game state is (H × I) + (F × G) × L (sheets).

Also, in the case of a general game state other than the BB game state and the RB game state per unit number of games, it is assumed that V (times) is awarded to the small winning combination of the payout number U (sheets), and the BB game state is M. (Times), if the RB game state occurs N (times), the number E of medals to be paid out is as follows (2)
It can be calculated using the equation. E = {(H × I) + (F × G) × L} × M + (F × G) × N + (U × V) ... (2) In the BB game state and / or the general game state,
There may be a plurality of types of small winning combinations, but here, it is explained that there is only one type of small winning combination in the BB gaming state and the general gaming state.

The number M of occurrences of the BB gaming state and the number N of occurrences of the RB gaming state are due to the probability that the player wins the lottery performed in response to the start of the game. The probability of winning the lottery is predetermined. However, if the game is not being played, the number M of times the BB game state occurs and RB
The number N of times the gaming state occurs can be adjusted by changing the setting inside the pachi-slot gaming machine.

The difference is the unit game number (for example, 1
For each (00 games), the number D of inserted medals and the number E of paid out medals are measured, and from the number D of game balls inserted and the number E of game balls paid out. It is possible to calculate. Further, the difference sheet number can be calculated as follows.

For example, the number D _{1 of} medals thrown in when playing 10 games and the number E _{1 of} medals paid out are measured, and thereafter, the number D _{2 of} medals thrown in every 10 games. , D ₃ , ... And the number of paid out medals E ₂ , E ₃ ,. And 100
After the game elapses, that is, when D ₁₀ and E ₁₀ are measured, D _{1 to} D ₁₀ are set to D, E _{1 to} E ₁₀ are set to E, and the difference number per unit game number (100 games) is calculated. Thereafter, when 10 games have passed, that is, when D ₁₁ and E ₁₁ are measured, D _{2 to} D ₁₁ are D, E _{2 to} E ₁₁ are E, and the number of unit games (10
The difference number per 0 games) is calculated. In this way, when the difference number per 100 games is calculated for every 10 games, the difference number is calculated by measuring the number D of inserted medals and the number E of medals paid out for each 100 games. Compared with the method, it is possible to calculate the difference number by finely adjusting the time interval, and it is possible to change the probability of winning the winning lottery described later by the difference number calculated finely, so the difference number is more reliably the upper limit. It can fall within the range from the value to the lower limit. In the above example,
Although the number of games is used as the reference unit, the time may be used as the reference unit when the difference ball number is obtained.

In the pachislo gaming machine, a method of calculating the difference number is, for example, a command signal transmitted from a control unit provided in the pachislo gaming machine, that is, a command signal for using a medal and a medal. A method of calculating the difference number based on the command signal for paying out can be cited.

In the case of the pachinko gaming machine, the "numerical value obtained by calculating the difference between the number of input game media and the number of payout game media" is, for example, a game ball shot on the game board per unit time (1 hour). It is the difference from the number of game balls paid out. In the present specification, the above numerical value is also referred to as the number of differential spheres.

When the number of game balls launched on the game board per unit time (1 hour) is A (ball) and the number of game balls dispensed is B (ball), the difference ball number X (ball) is It can be calculated using the following equation (3). X = B-A (ball) (3) In addition, the maximum number per unit time A of the game balls that are launched on the game board is set, and the number of game balls exceeds that number on the game board. It is set so that a game ball cannot be launched.

When the big hit state occurs, from the opening of the special winning opening until a predetermined number of game balls enter the special winning opening, or until a predetermined period of time elapses. The jackpot game, which is once, is repeated a plurality of times. When the number of payouts at the special winning opening is J balls, L is given to the special winning opening in all the jackpot games that are repeated K times.
If the game balls can be inserted, the number of game balls to be paid out is (J × L) × K balls.

When the number of payouts of the winning opening is P balls and the number of payouts of the starting opening is Q balls, the game ball is R times in the winning opening and the game is in the starting opening per unit time (1 hour). Assuming that the ball enters S times and the jackpot state occurs T times, the number B of game balls to be paid out can be calculated using the following formula (4). B = {(J × L) × K} × T + (P × R) + (Q × S) (4) In addition, the number L of game balls entering the special winning opening, the game ball entering the winning opening The number of times R and the number S of times the game ball enters the starting opening are
It changes depending on the positional relationship of a plurality of nails planted on the game board, and when the game is not being performed, by adjusting the angles of the plurality of nails and the like, adjustment is made to a certain extent. It is possible.

The number T of times the jackpot condition occurs is
It depends on the probability of winning the lottery that is performed in response to the game ball entering the starting opening, but the probability of winning the lottery is predetermined. In addition, the number K of jackpot games repeated when the jackpot state is occurring is also predetermined.

The number of difference balls is the number of game balls shot out and the number B of game balls paid out per unit time (for example, one hour), and the number of game balls shot out. It is possible to calculate it from the number A of B and the number B of game balls paid out. Moreover, the above-mentioned difference sphere number can also be calculated as follows.

For example, of a game ball launched in 10 minutes
Number A₁And the number of game balls B paid out ₁And measure
After that, every 10 minutes, the number A of game balls launched_Two, A
_Three,,, and the number of game balls B paid out_Two, B_Three,

To calculate the number of difference balls by measuring the number B of game balls played
Compared with, the time interval is finer and the number of difference balls is calculated.
It is possible to win the lottery according to the difference ball number calculated in detail
Since you can change the probability of winning,
It is possible to more surely fall within the range from the upper limit value to the lower limit value.
Wear.

In the pachinko game machine, as a method of calculating the number of difference balls, for example, a sensor capable of actually detecting a game ball shot on the game board,
A method that calculates the number of difference balls based on the number of game balls detected by each sensor with a sensor that can detect the game balls to be paid out (hereinafter, the number of difference balls is calculated by detecting the game balls Based on the command signal transmitted from the control unit provided in the pachinko gaming machine, that is, the command signal for launching the game ball on the game board and the command signal for paying out the game ball. And a method of calculating the number of differential spheres (hereinafter, also referred to as a method of calculating the number of differential spheres only in the control unit).

The "numerical value obtained by calculating the ratio of the number of payout game media to the number of input game media" is, for example, the number of unit games (for example, 100 games) in the pachi-slot gaming machine.
It refers to the ratio of the number of paid-out medals to the number of medals thrown around, and in the present specification, the above numerical value is also referred to as the payout rate. Further, the "numerical value obtained by calculating the ratio of the number of payout game media to the number of input game media" in the pachinko gaming machine is, for example, a payout game for the number of game balls hit on the game board per unit time (1 hour). It refers to the ratio of the number of balls,
In the present specification, the above-mentioned numerical value is referred to as a ball exit rate. In addition, the exit rate will be described in detail later.

Per unit game number (100 games),
When the number of inserted medals is D (sheets) and the number of paid-out medals is E (sheets), the payout rate Z (%) can be calculated using the following equation (5). Z = (E / D) × 100 (%) (5) It should be noted that the number D of medals inserted per unit number of games
Can be always kept below a predetermined number by setting the maximum number of medals that can be used in one game to a predetermined number (for example, 3).

The number E of medals to be paid out per unit game number can be obtained by the above equation (2).

The payout rate is the number of unit games (for example, 1
For each (00 games), the number of inserted medals is D, and the number of paid out medals is E, and is calculated from the number of inserted medals D and the number of paid out medals E. It is possible to

For example, the games introduced in the first 10 games
Number of dulls D₁And the number of medals E paid out₁And measure
The number of medals thrown in every 10 games thereafter
D_Two, D_Three,,, and the number E of game balls paid out_Two,
E_Three,, and are measured. And 100 games

Compared with the method of calculating the refund rate,
You can calculate the refund rate by doing
It is possible to change the probability of winning the lottery by the rate
Therefore, the refund rate can be more reliably ranged from the upper limit to the lower limit.
Can be stored in the enclosure. In the example described above,
We used the number of games as the unit of measure, but the above refund rate
When determining, the unit of reference is time
It may be done.

In the present invention, as a method of calculating the payout rate, for example, a command signal transmitted from a control unit provided in the pachi-slot gaming machine, that is, a command signal for using a medal and a medal are paid out. A method for calculating the difference number based on the command signal for

Next, "big hit" means the right of the player to enjoy the big hit state in the future. After the big hit occurs, when the symbol combination of the variable symbols stopped and displayed matches the predetermined symbol combination, the big hit state occurs and the big hit state is provided to the player. .

As the jackpot state, for example, in a pachinko gaming machine, the process of opening the special winning opening for a certain period of time and paying out game balls according to the number of game balls entering the special winning opening, It can be repeated intermittently, etc., and in the pachi-slot gaming machine, etc., the RB gaming state, the BB gaming state, etc. can be mentioned, and the player can obtain many gaming media.

As the predetermined combination of symbols, for example, a combination of symbols in which all the symbols of the variable symbols that are stopped and displayed are the same (for example, "7"-"7"-"7").
Etc.) etc. can be mentioned.

However, in a pachi-slot gaming machine or the like, even if a big hit occurs, if the timing at which the player stops the reels deviates from the timing at which a predetermined combination of symbols can be stopped on the activated line, The combination of predetermined symbols cannot be stopped on the activated line, and the jackpot state is not provided to the player.

"Big hit lottery" means an internal lottery for deciding whether or not a big hit should be generated. For example, in a pachinko gaming machine, a game ball is inserted into a starting opening, and in a pachislot gaming machine, a start lever is operated while a medal is inserted. It is like this. At this time, in the case of a pachislot machine, etc., if it is decided that a jackpot is generated in the jackpot lottery, the result of the jackpot lottery is RB, BB, etc. The result of is a small win, loss, etc.

Further, in the pachinko gaming machine, following the jackpot lottery, a symbol lottery for determining the symbols to be stopped and displayed will be performed. In this case, a symbol lottery table in which random numbers are associated with symbols to be stopped and displayed may be used. Further, it is also possible to determine whether or not to generate a jackpot and at the same time determine the symbols to be stopped and displayed.

Such a jackpot lottery, ROM (Read Only Memory) such as a control unit provided in the gaming machine,
A probability table that determines whether or not to win the jackpot is stored in advance in correspondence with the random number, and the RA of the control unit or the like is stored.
This can be performed by setting a necessary probability table in M (Random Access Memory) or the like, and then sampling random numbers by the control unit. At this time, the control unit provided in the gaming machine functions as a jackpot lottery means for performing a jackpot lottery. In addition, the first as described above
In the game method in which the lottery and the second lottery are performed, a combination of the first lottery and the second lottery is a big hit lottery.

On the other hand, the "winning" is the right of the player to enjoy the winning state, and means that the player has a greater chance of being able to generate the big winning state.

As the hitting state, in a pachinko gaming machine, for example, a movable piece provided on both sides of the starting opening may be left open for a certain period of time so that a game ball can easily enter. Further, in a pachi-slot gaming machine or the like, for example, of the internal winnings, the player can be informed of the small win, and the player can keep an eye on it.
A situation where the chance of missing a small winning a prize is reduced (hereinafter, A
T gaming state), a state in which the probability of winning a re-playing game in which the player can play the game by taking over the medals used in the previous game without using medals owned by the player (hereinafter, Also called RT gaming state), A
Examples include a state in which a player can play a game without consuming held medals, such as a state in which a T gaming state and an RT gaming state occur simultaneously (hereinafter also referred to as an ST gaming state). it can. In a pachislot machine, etc., the probability of a big hit is constant while the game is being played, so if a hit state occurs,
Since the player can play the game by re-playing or paid out medals, it is possible to increase the jackpot lottery without consuming held medals, and as a result, the player is more likely to play the game in the jackpot state. Will be.

Further, in one pachi-slot gaming machine, it is not necessary to provide all the AT gaming status, RT gaming status, ST gaming status, AT gaming status, RT gaming status, S gaming status.
Only one of the T gaming states may be provided, and the number of winning states provided by one pachi-slot gaming machine is not particularly limited. Further, when one pachi-slot gaming machine is provided with a plurality of gaming states such as an AT gaming state, an RT gaming state, and an ST gaming state, the hit state is the AT state.
It may refer to any one of the gaming state, the RT gaming state, the ST gaming state, etc., and may refer to the two, and the type of the winning state is not particularly limited. In the present invention, the AT game state, RT game state, ST game state, etc. are included in the general game state.

Further, in the pachi-slot gaming machine, etc., when the small winning combination is determined by the big hit lottery during this AT gaming state, the small winning combination is won by the lamp, the kind of the winning small winning combination, etc. To inform the player. At this time, the number of remaining games in the AT game state may be displayed on the display unit or the like.

The "winning lottery" is an internal lottery different from the big hit lottery, and means a lottery for determining whether or not to generate a win. In a pachinko machine, for example,
It is an internal lottery that is performed when the game ball passes near the ball passage detector, and it is decided whether to stop and display the ordinary symbol described later with the ordinary symbol that will be won or with other ordinary symbols. It Further, in a pachi-slot gaming machine or the like, for example, in the internal lottery performed after the BB gaming state ends, whether or not the player generates the right to enjoy the AT gaming state (hereinafter, also referred to as AT), The player is RT
Whether to generate the right to enjoy the gaming state (hereinafter, also referred to as RT), whether to generate the right to enjoy the ST gaming state (hereinafter, also referred to as ST), and the like are determined. The player may or may not be notified that the RT gaming state has been won.

The winning state may be provided to the player immediately after the winning is determined, or the winning state may be provided to the player after a predetermined time has passed after the winning is determined. In the pachi-slot gaming machine, the number of games in the AT gaming state, the RT gaming state, and the ST gaming state is not particularly limited, and may be, for example, 10 games or 30 games, and depending on the gaming status. May be changed as appropriate.

The winning lottery is not limited to one for one gaming machine, but may be three or any number. For example, it may be determined whether or not any one of AT, RT, and ST is generated in one winning lottery, whether or not AT is generated and whether RT is generated in three winning lottery. Alternatively, whether to generate ST may be determined. In addition, in the winning lottery, two winning lottery is performed in which a first winning lottery for determining whether to generate a winning is performed, and a second winning lottery for determining whether to generate a winning condition is performed. It may be used. In addition, when a plurality of winning lottery is performed with one gaming machine, in the present invention, the numerical value obtained by the calculating means falls within a predetermined range based on a predetermined upper limit value or lower limit value. In this case, the probability of winning the winning lottery is changed, but the number of winning lottery that changes the winning probability may be any number.

Further, the big winning lottery and the winning lottery are
The lottery may be performed so that the results of each lottery are independent from each other, or the lottery may be performed so that the result of one of the lottery influences the other. For example, when the number related to the number of game media falls within the predetermined range based on the lower limit, the probability of winning the winning lottery is increased, and then the winning lottery is performed. On the contrary, when the numerical value regarding the number of game media falls within a predetermined range based on the upper limit value, the probability of winning the winning lottery is reduced, and then the winning lottery is carried out. The winning probability of the jackpot lottery may be reduced. In this way, when the numerical value related to the number of game media falls within the predetermined range based on the upper limit value or the lower limit value, the winning lottery result is changed after changing the probability of winning the winning lottery. By changing the probability of playing, it is possible to ensure that the numerical value regarding the number of game media falls within the range from the upper limit value to the lower limit value.

In many gaming machines, the probability of winning the winning lottery is constant, and the game proceeds with the probability kept constant. However, in the present invention, the probability of winning the winning lottery is determined by By changing the probability of winning the winning lottery when the numerical value related to the number falls within the predetermined range based on the predetermined upper limit value or lower limit value, the numerical value related to the number of game media is changed from the upper limit value to the lower limit value. It should be within the range of.

The probability of winning the winning lottery is the number of game media and the upper limit or lower limit when the number of game media falls within a predetermined range based on the upper limit or the lower limit. It is desirable to change the probability of winning the winning lottery step by step in association with the difference of. By changing the probability of winning the winning lottery stepwise, it is possible to suppress a sudden change in the number of game media to be paid out, which is accompanied by a great change in the probability of winning the winning lottery. This is because it is possible to reliably prevent an extremely large amount or a small amount.

Also, the probability of winning the winning lottery is changed when the numerical value relating to the number of game media which has once entered a predetermined range based on the upper limit value or the lower limit value is out of the predetermined range. It is desirable to restore the probability of winning the lottery. By returning the changed winning probability to the winning lottery once, it is possible to suppress a sudden change in the number of game media to be paid out due to a change in the winning probability to the winning lottery, and to pay out the gaming medium. This is because it is possible to more surely prevent the number of the numbers from extremely increasing or decreasing.

Also in such a winning lottery, a ROM (Read Only Memory) such as a control unit provided in the gaming machine is stored with a probability table that determines whether or not to win in advance corresponding to a random number. In addition, the RAM (Ra
This can be done by setting a necessary probability table in (ndom Access Memory) or the like and then sampling random numbers by the control unit. At this time, the control unit provided in the gaming machine functions as a winning lottery means for performing a winning lottery. However, in this winning lottery, when the numerical value regarding the number of game media falls within a predetermined range based on the upper limit value, when it falls within a predetermined range based on the lower limit value,
If the probability table does not fall within these ranges, different probability tables are prepared, and the lottery is performed using the probability tables corresponding to the range of numerical values regarding the number of game media.

For example, a probability table for deciding whether or not to win a lottery corresponding to a random number of 0 to 64 is set to 0 when the numerical value related to the number of game media falls within a predetermined range based on the lower limit value. Wins corresponding to 32 random numbers, 3
If the numerical value relating to the number of game media is not within the predetermined range based on the upper limit value or the lower limit value, it is determined to be a winning corresponding to the random number of 0 to 16, and 17 to 17 If the numerical value relating to the number of game media falls within a predetermined range based on the upper limit value, it is won in correspondence with the random number of 0 to 4,
In correspondence with 64 random numbers
The probability of winning the winning lottery can be changed.

The "winning prize hole" is an opening provided on the game board so that the gaming ball can be inserted therein. 5
It is paid out with a ball.

In the present specification, the starting opening is an opening provided on the game board so that the game ball can be inserted therein. When the game ball enters the starting opening, the game ball is paid out in a predetermined number. Along with being paid out (for example, 5 balls), a lottery for deciding whether or not to generate a jackpot is performed in a control unit provided in the pachinko gaming machine. In addition, the display on the game board displays a variable pattern,
The variable display game is started. The difference between the winning opening and the starting opening is whether or not a lottery is performed to determine whether or not a jackpot is generated by entering a game ball, and other components are the same. May be different. In addition, in the present specification, the start opening is included in the above-mentioned "winning hole", and the big winning opening which is intermittently opened at a predetermined cycle while the big hit state is generated is also described above. It is included in the "winning prize". However, in response to the entry of the game ball, a lottery is performed to determine whether or not a jackpot is to be generated, but the starting opening where the game ball is not paid out only by the entry of the game ball is the present invention. It does not correspond to the winning opening provided in the gaming machine.

The "ball-out rate" means the ratio of the number of game balls paid out to the number of game balls hit on the game board per unit time (1 hour). The number of game balls launched on the game board per unit time (1 hour) is A (ball),
When the number of game balls to be paid out is B (ball), the payout rate X (%) can be calculated using the following formula (6). X = (B / A) × 100 (%) (6) It should be noted that the maximum number of game balls A hit on the game board is set per unit time and exceeds that number. It is set so that a game ball cannot be launched on the game board.

Regarding the game balls to be paid out, the game balls are paid out when the game ball has entered the special winning opening when the jackpot state has occurred, or the game ball to the winning opening or the starting opening. Will be paid out upon receipt of.

When the jackpot state occurs, from the opening of the special winning opening until a predetermined number of game balls enter the special winning opening, or until a predetermined period of time elapses. The jackpot game, which is once, is repeated a plurality of times. When the number of payouts at the special winning opening is J balls, L is given to the special winning opening in all the jackpot games that are repeated K times.
If the game balls can be inserted, the number of game balls to be paid out is (J × L) × K balls.

When the number of payouts at the winning opening is P balls and the number of payouts at the starting opening is Q balls, the game ball is R times in the winning opening and the game is in the starting opening per unit time (1 hour). Assuming that the ball enters S times and the jackpot state occurs T times, the number B of game balls to be paid out can be calculated using the following formula (7). B = {(J × L) × K} × T + (P × R) + (Q × S) (7) In addition, the number of times L the game ball enters the special winning opening, the game ball enters the winning opening The number of times R and the number S of times the game ball enters the starting opening are
It changes depending on the positional relationship of a plurality of nails planted on the game board, and when the game is not being performed, by adjusting the angles of the plurality of nails and the like, adjustment is made to a certain extent. It is possible.

The number of times T when the jackpot state occurs is
It depends on the probability of winning the jackpot lottery that is performed in response to the game ball entering the starting opening, but the probability of winning the jackpot lottery is predetermined. In addition, the number K of jackpot games repeated when the jackpot state is occurring is also predetermined.

The above-mentioned pitch rate is the number of game balls shot out A and the number B of game balls paid out per unit time (for example, one hour), and the number of shot game balls is set out. It is possible to calculate from the number A of B and the number B of game balls paid out. Further, the above-mentioned rate of exit can be calculated as follows.

For example, of a game ball launched in 10 minutes

Wear.

In the gaming machine of the present invention, as a method for calculating the above-mentioned ball-out rate, for example, a sensor capable of actually detecting a game ball hit on the game board and a pay-out game ball are detected. A sensor that can be provided, and a method of calculating the ball exit rate based on the number of game balls detected by each sensor (hereinafter, also referred to as a method of detecting a game ball and calculating the ball exit rate), Calculate the exit rate based on the command signal transmitted from the control unit provided in the pachinko gaming machine, that is, the command signal for launching the game ball on the game board and the command signal for paying out the game ball. A method (hereinafter, also referred to as a method of calculating a ball exit rate only in the control unit) and the like can be mentioned. It should be noted that a method of detecting a game ball and calculating an exit rate and a method of calculating an exit rate only in the control unit will be described later.

The "ordinary pattern" is information consisting of numbers and symbols, for example, numbers from "0" to "9" and symbols such as "☆". When this normal symbol is displayed as a predetermined symbol, for example, "7" which is a normal symbol to be won and is stopped and displayed, the movable pieces provided on both sides of the starting opening are opened to facilitate the entry of game balls. To be Further, after a predetermined time has elapsed after the starting port is opened, the movable piece is closed to prevent the game ball from entering easily.

The "ordinary symbol lottery" is a lottery performed when a game ball passes near the ball passage detector, and the above ordinary symbol is stopped and displayed as an ordinary symbol that wins or other ordinary symbols. A lottery for deciding whether or not to stop and display a symbol. In many pachinko gaming devices, the probability of winning a regular symbol lottery is constant, and the game proceeds with the probability kept constant, but in the present invention, the probability of winning a regular symbol lottery is the exit rate. Is changed when the value approaches a predetermined upper limit value or a lower limit value, so that the ball-out rate falls within the range from the upper limit value to the lower limit value.

Further, the value for changing the probability of winning in the normal symbol lottery (winning probability) is not particularly limited, and the lower limit of the rate of departure is 30%, the upper limit is 300%, and the lower limit is the standard. The predetermined range is 30 to 50%, the predetermined range based on the upper limit is 270 to 300%,
When the winning probability is set to 60% when the percentage is more than 270% and less than 270%, for example, when the winning percentage is 30 to 50%, the winning probability is increased to 90% and the winning percentage is increased. When 270-300% is entered, the winning probability can be changed to 30% so that the probability of winning the ordinary symbol lottery can be changed.

The probability of winning the ordinary symbol lottery is related to the difference between the rate of departure and the upper limit value or the lower limit value when the rate of departure is within a predetermined range based on the upper limit value or the lower limit value. ,
It is desirable to change the probability of winning the ordinary symbol lottery stepwise. By changing the probability of winning the regular symbol lottery in stages, it is possible to suppress the rapid change in the ball-drawing rate associated with a large change in the probability of winning the ordinary symbol lottery, and the ball-drawing rate is extremely high. This is because it can be surely prevented from becoming low or low.

Further, the probability of winning the ordinary symbol lottery is, once the exit rate within the predetermined range based on the upper limit value or the lower limit value, when the deviation from the above predetermined range, changed the normal symbol lottery It is desirable to return the probability of winning to.
Once, by returning the changed probability of winning the normal symbol lottery to the original, it is possible to suppress the rapid change in the ball-out rate associated with changing the probability of winning the ordinary symbol lottery,
This is because it is possible to more reliably prevent an extremely high or low exit rate. For example,
While the probability of winning a regular symbol lottery was increased from 60% to 90% when the rate of entry was in the range of 270 to 300%, while the rate of entry was below 270%, The probability of winning is returned to 60%,
It is possible to restore the changed probability of winning the ordinary symbol lottery.

In addition, in such a lottery, a probability table for determining whether or not to win is stored in advance in a ROM (Read Only Memory) of a control unit or the like provided in the gaming machine, corresponding to a random number. In addition, the RAM (Random A
It is possible to set a necessary probability table in a ccess memory), and then to sample random numbers by the control unit. At this time, the control unit provided in the gaming machine functions as a normal symbol lottery means for performing a regular symbol lottery. However, in this lottery, different probability tables are used when the exit rate falls within a predetermined range based on the upper limit value, when it falls within a predetermined range based on the lower limit value, and when it does not fall within these ranges. Is available,
The lottery will be carried out using the probability table corresponding to the range of the above-mentioned ball launch rate.

For example, a probability table for determining whether to win or lose the lottery corresponding to a random number of 0 to 64 is set to 0 when the discharge rate falls within a predetermined range based on the lower limit value.
Corresponding to a random number of 32, it is won, and corresponding to a random number of 33 to 64, it is deviated, and when the rate of departure is not within a predetermined range based on the upper limit value or the lower limit value, it corresponds to a random number of 0 to 16 Then, it is judged as a win, corresponding to a random number of 17 to 64, and when it is within a predetermined range based on the upper limit value, it is judged as a win in response to a random number of 0 to 4,
It is possible to change the probability of winning in the ordinary symbol lottery, such that it is out of correspondence with the random number. At this time, following the lottery for determining whether to win or lose, a lottery for determining the ordinary symbols to be stopped and displayed is performed. In this case, a lottery table in which a random number and a normal symbol that is stopped and displayed are associated with each other may be used. Further, at the same time as determining whether to win or lose, it is also possible to determine the normal symbol that is stopped and displayed.

At the same time as the lottery for deciding the ordinary symbols to be stopped and displayed, and for determining whether to win or lose
In the lottery that determines the normal symbol that is stopped and displayed, instead of sampling random numbers, a counter that corresponds the maximum count value to the number of ordinary symbols is provided in the game machine, and the game ball near the ball passage detector. When passing, the lottery may be performed by extracting the numerical value counted by the counter.

FIG. 5 is a flowchart showing a subroutine executed to count the number of game balls hit on the game board. It should be noted that this subroutine is called and executed at a predetermined timing from a control program that controls the pachinko game of the pachinko gaming machine 10 that has been executed in advance.

First, the number of game balls shot on the game board (the number of shots detected A) stored in the RAM 70 is set to 0 (step S100). Next, it is determined whether or not the game ball shot by the launch motor 28 has been detected by the launch ball passage detector 61 (step S101). If it is determined that it has not been detected, the process proceeds to step S1.
Return to 01.

When it is determined that the launch ball passage detector 61 has detected it, it is next determined whether or not the launched game ball has been detected by the return detection switch 65 (step S102). That is, the CPU 66 determines whether or not the detection signal from the return ball detection switch 65 has been received.

When it is determined that the game ball is detected by the return detection switch 65, the process is returned to step S101. On the other hand, when it is determined that the game ball is not detected by the return detection switch 65, 1 is added (incremented) to the firing detection number A stored in the RAM 70, and A +
1 is cumulatively stored in the RAM 70 (step S10).
3).

Next, it is determined whether or not a predetermined period has elapsed since the process of step S100 was executed (step S104). When it is determined that the predetermined period has not elapsed, the process is returned to step S101, and the processes of steps S101 to S103 are executed again. Note that instead of step S104 described above, steps S101 to S1.
It is also possible to forcibly execute the process of step S105 described below and terminate the present subroutine when a predetermined period of time elapses while the process of 03 is being executed.

In this way, until it is determined in step S104 that the predetermined period has elapsed, step S101
By repeatedly executing the processing of to S103, it becomes possible to measure the number of game balls launched within a predetermined period. When it is determined in step S104 that the predetermined period has elapsed, the number A of shots detected within the predetermined period is stored in the RAM 70 (step S10).
5) Then, this subroutine is finished. In addition, when the subroutine for measuring the number of game balls hit on the game board is being executed, the launch ball passage detector 61, the return ball detection switch 65, and the launch ball passage detector 61 and the return. The control unit (CPU 66) that receives the detection signal from the ball detection switch 65 functions as a hitting game ball measuring means for obtaining the number of hit game balls.

FIG. 6 is a flowchart showing a subroutine executed to count the number of game balls paid out. Note that this subroutine is called and executed at the same time as the launch game ball measurement processing routine shown in FIG. 5 is executed from a control program that controls the pachinko game of the pachinko game machine 10 that has been executed in advance. It is something.

First, the CPU 66 sets the number of paid-out game balls (payout detection number B) stored in the RAM 70 to 0 (step S110). Next, the payout ball detection sensor 5
It is determined whether or not the game ball is detected by 3 (step S111). If you determine that it has not been detected,
The process returns to step S111.

When it is determined that the payout ball detection sensor 53 detects the payout ball, the payout detection number B stored in the RAM 70 is incremented by 1, and B + 1 is set to R.
It is cumulatively stored in the AM 70 (step S113). next,
It is determined whether or not a predetermined period has elapsed since the process of step S110 was executed (step S114).
The predetermined period referred to here may be the same as or different from the predetermined period in the subroutine described with reference to FIG. When it is determined that the predetermined period has not elapsed, the process is returned to step S111, and the processes of steps S111 and S113 are executed again.

Thus, until it is determined in step S114 that the predetermined period has elapsed, step S111 is performed.
By repeatedly executing the processing of S113 and S113, it becomes possible to measure the number of gaming balls paid out in a predetermined period. When it is determined in step S114 that the predetermined period has elapsed, the payout detection number B within the predetermined period is stored in the RAM 70 (step S11).
5) Then, this subroutine is finished. It should be noted that when the subroutine for measuring the number of paid-out game balls is being executed, the pay-out ball detection sensor 53 and a control unit (CPU that receives a detection signal from the pay-out ball detection sensor 53)
66) functions as a payout game ball measuring means for obtaining the number of paid game balls.

FIG. 7 is a flow chart showing a subroutine for detecting a game ball executed in the control circuit 60 described above. It should be noted that this subroutine is called and executed at a predetermined timing from a control program that controls the pachinko game of the pachinko gaming machine 10 that has been executed in advance.

First, the CPU 66 executes the above-mentioned step S.
The number of firing detections A stored in the RAM 70 at 105,
Then, the payout detection number B stored in the RAM 70 in step S115 is read out, and the process of calculating the ball-out rate by the above equation (1) is performed (step S11). The frequency of performing the ball-out rate calculation process is not particularly limited, and examples thereof include every 5 minutes and every 10 minutes. The rate is calculated. In step S120, the control unit (C
The PU 66) functions as a discharge rate calculating means for calculating a discharge rate from the number of game balls hit and the number of game balls paid out.

Next, it is detected whether or not a game ball has entered the winning opening (step S12). The winning openings are, for example, the general winning openings 50 and 54a to 54d and the special winning openings 56a to 56d in the example shown in FIG. When it is determined in step S12 that a game ball has entered the winning opening, the payout device 59 is driven to execute a process of paying out a predetermined number of gaming balls according to the type of the winning opening (step S13).

Next, it is determined whether or not a game ball has entered the starting opening (step S14). This starting port is, for example, the starting port 44 in the example shown in FIG. 2 described above.
In this step S14, when it is determined that a game ball has entered the starting opening, the payout device 59 is driven to execute a process of paying out a predetermined number of game balls (step S15), and further, a variable display described later. The game is executed (step S16). Step S13 or S1 described above
When 6 is executed, the payout device 59 and the control unit that transmits a command signal to the payout device 59 to pay out the game balls function as a payout means.

Further, it is determined whether or not the game ball has passed the ball passage detector (step S17). This sphere passage detector is, for example, the sphere passage detectors 55a and 55b in the example shown in FIG. 2 described above.

In this step S17, when it is determined that the game ball has passed the ball passage detector, it is determined whether or not the value of the rate of discharge is within a predetermined range based on the upper limit value or the lower limit value. (Step S18). The above-mentioned rate of departure is
As described above, it is a value based on the stored ball-out rate calculated and stored at regular intervals. When it is determined that the rate of departure is within a predetermined range based on the upper limit value or the lower limit value, the following processing is performed. That is, if the exit rate falls within the predetermined range based on the upper limit value, the probability of winning the ordinary symbol lottery is increased, and if it falls within the predetermined range based on the lower limit value, The probability of winning the ordinary symbol lottery is reduced (step S20).

Further, the value for changing the probability of winning the ordinary symbol lottery is not particularly limited, and the lower limit value of the ball launch rate is 30%, the upper limit value is 300%, and a predetermined range based on the lower limit value. 30% to 50%, the predetermined range based on the upper limit is 270 to 300%, and the rate of departure is more than 50% and 270
When it is less than%, the probability of winning the ordinary symbol lottery is 60
%, For example, when the exit rate is 30 to 50%, the winning probability is increased to 90%, and the exit rate is 27.
When entering 0-300%, the winning probability is 30%
It is possible to change the probability of winning the normal symbol lottery, such as decreasing to.

The probability of winning the ordinary symbol lottery is related to the difference between the rate of departure and the upper or lower limit value when the rate of departure is within a predetermined range based on the upper or lower limit value. ,
It is desirable to change the probability of winning the ordinary symbol lottery stepwise. By changing the probability of winning the regular symbol lottery in stages, it is possible to suppress the rapid change in the ball-drawing rate associated with a large change in the probability of winning the ordinary symbol lottery, and the ball-drawing rate is extremely high. This is because it can be surely prevented from becoming low or low.

Further, the probability of winning in the ordinary symbol lottery is that the ordinary symbol lottery is changed when the exit rate within the prescribed range based on the upper limit value or the lower limit value deviates from the prescribed range. It is desirable to return the probability of winning to.
Once, by returning the changed probability of winning the normal symbol lottery to the original, it is possible to suppress the rapid change in the ball-out rate associated with changing the probability of winning the ordinary symbol lottery,
This is because it is possible to more reliably prevent an extremely high or low exit rate. For example,
While the probability of winning a regular symbol lottery was increased from 60% to 90% when the rate of entry was in the range of 270 to 300%, while the rate of entry was below 270%, The probability of winning is returned to 60%,
It is possible to restore the changed probability of winning the ordinary symbol lottery.

On the other hand, when it is determined that the payout rate is not within the predetermined range based on the upper limit value or the lower limit value, the probability of winning the ordinary symbol lottery is set to the initial value (step S19). That is, in step S20, if the probability of winning in the ordinary symbol lottery is changed, and if the rate of departure is not within the predetermined range based on the upper limit value or the lower limit value, the changed ordinary symbol lottery is won. The probability of doing so is returned to the original value, that is, the initial value (60% in the above case).

As a method of changing the probability of winning in the ordinary symbol lottery, the CPU 66 stores a plurality of probability tables used in the ordinary symbol lottery in the ROM 68, and the exit rate is within a predetermined range based on the upper limit value. When entering, when entering a predetermined range based on the lower limit value, and when deviating from the predetermined range based on the upper limit value and the lower limit value, different probability tables are set in the RAM 70, and It is possible to change the probability of winning the ordinary symbol lottery using the probability table corresponding to the range of the rate.

Next, the normal symbol lottery process by the calculation process of the CPU 66 is executed (step S21). In this normal symbol lottery process, a lottery is performed with the above-described probability, it is determined whether or not it is won, and the symbols that have been variably displayed are stopped and displayed, and the symbols when the symbols are confirmed are predetermined processes. is there. That is, the CPU 66 sets the data corresponding to the numerical value obtained by sampling the random numbers in the probability table set in the RAM 70 as the lottery result. At this time, the control unit provided in the gaming machine functions as an ordinary symbol lottery means for performing an ordinary symbol lottery. Next, in accordance with the result of the ordinary symbol lottery in step S21, the CPU 66 executes a process of variably displaying the ordinary symbol on the display device 52 so that the symbol determined by the ordinary symbol lottery process is stopped and displayed in step S22. Then, the stop display process is performed.

Further, according to the result of the ordinary symbol lottery in step S21, it is determined whether or not the regular symbol lottery process is won (step S23). When the normal symbol lottery process is won, the movable pieces 58a and 58b are driven to open the starting opening 44 so that the game ball easily enters the starting opening 44 (step S2).
4). On the other hand, when it is determined that the normal symbol lottery process is not won, or when the process of step S24 is executed, this subroutine is ended.

Next, the variable display game will be described.
FIG. 8 is a flowchart showing a subroutine that executes the variable display game process called and executed in step S16 described above.

By calling the subroutine shown in FIG. 8, the fixed screen displayed on the display device 32 is switched to the normal screen, and the variable display game is started. Here, the variable display game is a game imitating a game played in a slot machine, and a plurality of symbols, which are a plurality of identification information, are displayed on the display device 32, and after each of them is displayed so as to change, a predetermined pattern is displayed. These symbols are displayed so as to be stopped sequentially at the timing of, and when the combination of symbols when all the symbols are stopped becomes a predetermined combination, the pachinko game is shifted to a state advantageous to the player. This is a game in which the variable display and the stop display are executed as one stroke.

For example, as one set of symbols consisting of 12 numbers consisting of "1", "2", ..., "12", these 12 symbols are sequentially displayed on the display device 32, and the symbols are displayed. While the symbols are displayed to move, the symbols themselves are displayed to change. For example, on the display device 32, the symbol "1" is displayed so as to be scrolled from the top to the bottom of the display device 32, and then the symbol "2" is displayed so as to be scrolled from the top to the bottom. Similarly, "3" is displayed so as to scroll from top to bottom. After the symbols "1" to "12" are displayed in this manner, the symbols "1" are again displayed so as to be scrolled, and the same display is sequentially repeated.

By displaying the symbols on the display device 32 in this way, the symbols are sequentially changed while scrolling from "1" to "2" and from "2" to "3". Up to 12 "will be displayed, and then" 1 "will be displayed again. In this way, the mode of displaying the symbols so that the symbols themselves are sequentially changed while moving the position of one symbol is called variable display. Further, a mode in which a certain symbol is stopped and displayed is referred to as a stop display.

The symbols belonging to one set are displayed on the display device 3
When displaying in 2, the symbols to be displayed are not limited to only one symbol belonging to the set, and a plurality of symbols, for example, two to three symbols may be displayed at the same time. For example, when the symbol “5” is variably displayed on the display device 32, a part or the whole of the symbol “4” is variably displayed below the symbol “5”, and the symbol “6” is above the symbol “5”. May be displayed in a variable manner. The above-mentioned symbol group is a concept corresponding to the symbol group displayed on one reel used in the slot machine.

Further, when the variable display game is executed on the display device 32, the symbols belonging to each of the plurality of groups are displayed. For example, when each of the symbols belonging to the three groups is displayed in the horizontal direction, the symbols belonging to one group are displayed on the left side of the display device 32, and the symbols belonging to another group are displayed on the display device 32. The symbols displayed in the center and belonging to the remaining groups are displayed on the right side of the display device 32.

By displaying the symbol which is the identification information in this manner, a plurality of pieces of identification information are displayed on the display device 32 which is the display unit. For example, in the case of performing variable display so that only one of the symbols belonging to one set is always displayed, the display device 32
The three symbols are displayed, that is, one symbol is displayed on the left side, one symbol is displayed on the center, and one symbol is displayed on the right side. Further, the number of groups when the variable display game is executed is not limited to three, and symbols belonging to a plurality of groups other than three may be displayed on the display device 32.

As described above, by displaying the symbols in this way, a plurality of symbols, that is, a plurality of pieces of identification information, are displayed on the display device 32 which is the display unit. Further, as described above, a plurality of symbols may be displayed for symbols belonging to one group, and for example, two symbols belonging to one group may be displayed so as to be variably displayed at the same time. In the case of displaying the set, a total of 6 symbols are variably displayed on the display device 32.

After the symbols belonging to a plurality of groups are variably displayed,
When all symbols that have been variably displayed are stopped and displayed at a predetermined timing, and when the combination of these symbols is stopped and displayed in accordance with the predetermined combination, the variable display game is considered to have been won in the jackpot lottery game. Shifts to a state in which is advantageous to the player.

For example, when symbols belonging to three groups are displayed on the display device 32, symbols belonging to one group are stopped and displayed at "7", and symbols belonging to other groups are also stopped and displayed at "7". When the symbols belonging to the remaining groups are also stopped and displayed at "7", the symbol combination matches the predetermined combination "7"-"7"-"7", and the variable display game is won in the jackpot lottery. As a result, the state of the pachinko game shifts to a state in which it is advantageous to the player. When a big hit occurs, and when it shifts to a state that is advantageous to the player, a current is supplied to the solenoid 48 to open the shutter 40 of the special winning opening 38 provided on the front surface of the game board 14 to play the game. This makes it easier for the ball to enter the special winning opening 38.

Further, when the variable display game is executed, a display screen including a background image, a character image, etc. is also displayed on the display device 32. Note that the fixed screen described above is a screen displayed on the display device 32 when only the pachinko game is progressing on the pachinko game device 10 and the variable display game executed on the display device 32 is not being executed. Say.

Further, the normal screen means that when the variable display game reaches the reach or the jackpot state after the variable display game is started on the display device 32 and the symbols displayed on the display device 32 are variably displayed. The production screen displayed on the display device 32 during the process.

When the variable display game described above is started,
First, the internal lottery process is executed by the calculation process of the CPU 66 (step S200). This internal lottery process is a process of predetermining a symbol combination when all symbols belonging to a plurality of variably displayed groups are stopped and displayed and the symbol is fixed, and the CPU 66, as described later,
The variable display and the stop display of the symbols are performed so that the symbols are stopped and displayed in the combination of the symbols determined by the internal lottery process.

Next, the screen configuration information of the selected background image is generated in the RAM 70 (step S201). That is, after the internal lottery process is executed, the CPU 66 executes a control program for selecting a background image according to the result of the internal lottery process, the progress status of the variable display game, and the like.
It is called from the ROM 68 and executed.

Next, based on the result obtained by the CPU 66, the screen configuration information of the selected background image is generated in the RAM 70 by the CPU 66 at any time. The background image is not particularly limited, and is appropriately selected by the CPU based on the progress status of the variable display game and the result of the internal lottery process.

Next, the screen configuration information of the selected character image is generated in the RAM 70 (step S20).
2). That is, the screen configuration information of the character image selected by the CPU 66 is generated in the RAM 70 based on the execution result of the control program.

At this time, for example, 1/60 seconds or 1/3
By controlling the head position of the character image to shift by a predetermined movement amount at a constant interval (frame span) such as 0 seconds, it is possible to give a motion to the character image for display. The image showing the character does not always have to be displayed on the display device. The character image is also not particularly limited, and is appropriately selected by the CPU based on the progress status of the variable display game and the result of the internal lottery process.

Next, the screen configuration information of the variable pattern, which is the identification information, is based on the execution result of the control program.
It is generated in the RAM 70 by the CPU 66 (step S203).

The screen configuration information of the images which are the respective symbols forming the variable symbol is, for example, 1/60 second or 1/60 by the CPU 66 based on the above-mentioned control program.
With a fixed interval cycle (frame span) such as 30 seconds, for images that are variable patterns having the same identification information, the start position of the screen configuration information is shifted by a predetermined movement amount, and each variable pattern is also changed. By controlling such images to be sequentially generated in a predetermined order, it is possible to perform variable display of variable symbols.

Furthermore, since the changing speed of the variable symbol can be controlled by adjusting the frame span, the starting position of reading the screen configuration information, etc., the background image can be adjusted according to the story or the like developed in the background image. It is also possible to make the fluctuation of the fluctuation pattern smooth and to fuse the background image and the fluctuation pattern.

It should be noted that the ROM 68 stores a plurality of image data of different shapes for the same variable pattern,
By reading out from the CPU 66 and transmitting it to the display device 32 at any time, it is also possible to display the shape of the variable symbol such that the shape of the variable symbol changes with time during variable display.

Next, in steps 201 to 203, based on the screen configuration information generated in the RAM 70,
Each image data corresponding to the screen configuration information is read from the ROM 68 by the CPU 66. After that, the image data is displayed on the display device 32 according to the information regarding the displayed priority order, position, etc. in the screen configuration information, and then transmitted to the display device 32 and displayed (step S204).

The processes of steps S201 to S204 described above are repeatedly executed until it is determined in step S207, which will be described later, that all the symbols belonging to the plurality of groups have been stopped and displayed. By repeatedly executing such processing, it is possible to variably display the symbols in a predetermined manner and also to display the character image so as to perform a predetermined motion.

Next, it is judged whether or not it is time to stop and display the symbols belonging to one of the three groups (step S205). When it is determined that it is time to stop and display the symbol, one variable symbol is stopped and displayed (step S206). Step S described above
In 205, when it is determined that it is not time to stop and display the symbols, or when the process of step S206 is executed, it is determined whether or not all the symbols belonging to the plurality of groups have been stopped and displayed (step S207).

If it is determined that all of the symbols belonging to the plurality of groups are not stopped and displayed, the process proceeds to step S20.
Return to 1. On the other hand, if it is determined that all of the symbols are stopped and displayed, then it is determined whether or not the combination of symbols of the plurality of variable symbols that are stopped and displayed matches the combination of the symbols that are in the jackpot state (step S20).
8). However, regarding whether or not the combination of the symbols of the three variable symbols that are stopped and displayed matches the combination of the symbols that are in the jackpot state, the above-described step S200.
It is determined in advance by the result of the internal lottery process in.

In step S208, when it is determined that the combination of the symbols of the plurality of variable symbols stopped and displayed coincides with the combination of the symbols that are in the jackpot state,
The jackpot state is entered, the subroutine of the jackpot execution process shown in FIG. 9 is executed, and, for example, the jackpot is opened a plurality of times (step S209). On the other hand, when it is determined that the combination of the symbols of the plurality of variable symbols that are stopped and displayed does not match the combination of the symbols that are in the big hit state, this subroutine is ended.

By executing the variable display game processing routine described above, the variable display and the stop display of the variable symbols are performed on the display device 32, and further, the moving image having a certain narrative property is displayed, and the variable display is performed. The display game will be heaped up, and an effect that will attract the player's interest in the game will be performed.

Next, the jackpot execution processing routine executed when the jackpot state occurs in step S210 shown in FIG. 8 will be described with reference to FIG. In addition, in the following description, 1 is intermittently given in the jackpot state.
Five big hit games will be offered. In addition, the jackpot game, after the special winning opening is in the open state,
It is assumed that the game is performed once until 10 game balls enter the special winning opening or until a predetermined time elapses.
Furthermore, one jackpot game is also called one round.

In this big hit execution processing routine,
First, n, which is the number of jackpot games, is set to n = 1 (step S301). That is, the CPU 66 causes the RA
The fact that n = 1 is stored in a table (round number storage table) for storing the number of jackpot games provided in M70.

Next, it is determined whether or not it is time to open the special winning opening 38 (step S30).
2). When it is determined that it is time to open the special winning opening 38, the special winning opening 38 is opened (step S303). That is, the CPU 66 supplies the drive signal to the solenoid 48 via the interface circuit group 72 to open the special winning opening 38. This allows the player to insert a game ball into the special winning opening 38. On the other hand, when it is determined that it is not the timing when the special winning opening 38 is opened, the process returns to step S302.

Next, it is determined whether or not a game ball has entered the special winning opening 38 (step S304). Whether or not the game ball has entered the special winning opening 38 is determined by, for example, whether or not the game ball is detected by a sensor provided in the special winning opening 38. Then, when the game ball is detected by the sensor provided in the special winning opening 38, the detection signal is supplied to the interface circuit group. CPU that received this detection signal
66 stores the number of game balls in a table (large prize hole game ball storage table) that stores the number of game balls in the special winning opening provided in the RAM 70 (step S305), and further, the payout device 59. The game ball is driven and a process of paying out the game balls at a predetermined payout number J is executed (step S306). In step S306, the payout device 59 and the control unit that transmits a command signal for paying out the game ball to the payout device 59, in response to the fact that one game ball has entered the winning opening,
It functions as a payout means for paying out the game balls in a predetermined payout amount.

In step S304, the special winning opening 38
When it is determined that there is no game ball in, or when the process of paying out the game ball is executed in step S306, it is next determined whether or not a predetermined number of game balls have entered the special winning opening 38. (Step S307). That is, CP
U66 compares the number of game balls stored in the special winning opening game ball storage table with the predetermined number of game balls (10 balls) stored in another area of the RAM, and enters the special winning opening 38. It is determined whether or not the number of game balls is a predetermined number (10 balls).

When it is determined that the predetermined number of game balls has not entered the special winning opening 38, it is determined whether or not a predetermined time has passed since the special winning opening 38 was opened (step S308). ). That is, the CPU 66 executes step S
It is determined whether the elapsed time count started at 302 has reached a predetermined time. When it is determined that the predetermined time has not passed since the special winning opening 38 was opened, the process is returned to step S304.

On the other hand, when it is determined in step S307 that a predetermined number of game balls have entered the special winning opening 38, or when it is determined in step S308 that a predetermined time has elapsed, the special winning opening 38 is closed. (Step S309). In this way, the opening time of the special winning opening 38 is determined by either the number of game balls entering the special winning opening 38 or the time, and if a predetermined number of game balls enter the special winning opening 38. Even if the predetermined time has not been reached, the special winning opening 38 is closed, while even if the number of game balls entering the special winning opening 38 has not reached the predetermined value, if the predetermined time has passed, the big winning prize The mouth 38 is closed. In addition, 38
Is closed by supplying a drive signal to the solenoid 48 via the interface circuit group 72.

Next, 1 is added to n, which is the number of jackpot games, to set n = n + 1 (step S310). That is, the CPU 66 stores the number of jackpot games in the round number storage table provided in the RAM 70 so that n = n + 1. Then, it is determined whether or not the number n of jackpot games is 15 or less (step S311). That is, the CPU 66 first reads the number of jackpot games stored in the round number storage table, compares this number with the data of n = 15 stored in another area of the RAM, and determines the number n of jackpot games. It is determined whether or not n ≦ 15. When it is determined that the number n of jackpot games is n ≦ 15, the process is returned to step S302. Therefore, in this subroutine, the jackpot game is repeatedly played until n exceeds 15. And n, which is the number of jackpot games, is 15
When exceeds, this subroutine is finished. Although the maximum number of n is set to 15 in this subroutine, n is not limited as long as it is a natural number, and may be larger or smaller than 15. Further, while the jackpot execution processing routine described above is being executed, the display device 32 causes the player to recognize that the jackpot state has occurred, and displays an effect image for exciting the game.

In the present invention, when the rate of exit is within a predetermined range based on the lower limit value, the probability of winning the normal symbol lottery is increased to increase the probability that the starting opening will be open. Therefore, the number of game balls entering the starting port is increased, the probability of a big hit is increased, the probability of receiving a large number of game balls is increased, and the ball exit rate can be increased. On the contrary, when the exit rate falls within a predetermined range based on the upper limit value, it is possible to reduce the exit rate by reducing the probability of winning the ordinary symbol lottery.

As described above, in the pachinko gaming machine according to the present invention, for example, when the rate of discharge is close to the lower limit value, the probability that the starting opening is opened by increasing the probability of winning the ordinary symbol lottery To increase the chances of winning a large number of game balls, thereby suppressing the decrease in the rate of exit, and conversely, when the rate of exit is approaching the upper limit, reduce the probability of winning the ordinary symbol lottery As a result, it is possible to reduce the probability that the starting opening is opened and reduce the chances that a large number of game balls can be acquired, and thus to suppress the increase in the rate of exit. In this way, when the exit rate approaches the upper limit or the lower limit, the probability of winning in the ordinary symbol lottery is changed to adjust the number of game balls paid out per unit time, and the exit rate falls from the upper limit to the lower limit. In order to keep the value within the range up to the value, it is possible to omit the inspection of the ball exit rate or the like performed at the test site, and for example, it is possible to deal with only the spot inspection. In addition, even if the inclination of multiple nails planted on the game board is adjusted, the number of game balls paid out per unit time is adjusted so that the rate of discharge is from the upper limit to the lower limit. Since the value is kept within the range up to the value, the upper limit value is hardly exceeded or the lower limit value is not exceeded, and a sound game can be provided to the player.

In the above embodiment, a program for controlling the pachinko game and a program for executing the subroutine described with reference to FIGS. 5 to 9, that is,
A program that measures the number of game balls that have been launched, a program that detects the number of game balls, a program that measures the number of game balls that have been paid out, calculates the ball exit rate, and win the normal symbol lottery The ROM of the pachinko gaming machine 10 includes a program for changing the probability, a program for executing a variable display game, and a program for generating a jackpot state.

The variables used in the CPU 82 and the CPU 82 are assumed to have been initialized to predetermined values. In the following description, devices such as a winning opening, a starting opening, a ball passage detector, etc. and game balls are displayed as images on the display device 116.

A program for controlling a pachinko game and a program for executing a variable display game are stored in advance in the ROM 110 of the pachinko gaming terminal device 100 or 140, and various types are required as the pachinko game progresses. 14 to 18 show subroutines executed in the pachinko gaming terminal device 100 or 140 and the server 80 in the case where only the image data of the above is appropriately transmitted from the server 80.

FIG. 14 is a subroutine executed to detect the number of game balls, which is the pachinko gaming terminal device 1.
00 or 140. This subroutine is read out from the ROM 110 and executed at a predetermined timing from the main routine.

First, the number of game balls launched on the game board (launch detection number A) stored in the RAM 112 is set to 0 (step S150), and the number of game balls dispensed (payout detection number). B) is set to 0 (step S151).

Next, it is determined whether a game ball has been launched (step S152). That is, the CPU 108
Is an input device 10 provided in the terminal 100 or 140.
From 2, it is determined whether the player's input operation is input. If it is determined that the game ball has been launched, RAM11
1 is added (incremented) to the number A of firing detections stored in 2, and is cumulatively stored in the RAM 112 as A + 1 (step S153).

Next, it is determined whether or not the game balls have been paid out (step S154). That is, whether the game ball has been paid out by executing the process of step S35 or S37 described below, or whether the game ball has been paid out by executing the process of step S306 shown in FIG. to decide. When it is determined that the gaming balls have been paid out, 1 is added (incremented) to the payout detection number B stored in the RAM 112, and the RAM is set as B + 1.
The data is cumulatively stored in 112 (step S155).

Next, it is determined whether or not a predetermined period has elapsed since the process of step S151 was executed (step S156). When it is determined that the predetermined period has not elapsed, the process is returned to step S152, and the processes of steps S152 to S155 are executed again.

Thus, until it is determined in step S156 that the predetermined period has elapsed, step S152
By repeatedly executing the processing from S156 to S156, it is possible to measure the number of game balls hit in a predetermined period and the number of game balls paid out. Step S15

, Functions as a launched game ball measuring means for obtaining the number of launched game balls and as a paid-out game ball measurement means for obtaining the number of delivered game balls.

FIG. 15 shows a pachinko gaming terminal device 100.
Alternatively, it is a subroutine executed in 140, and in the following description, it is assumed that the main routine is read from the ROM 110 at a predetermined timing and executed. It is assumed that this main routine includes in advance a program necessary for communicating with the server 80, such as a program for determining whether communication with the server 80 is possible.

First, the pachinko game is started by the operation of the player, and the game program is executed (step S32). This game program is a game program that controls a pachinko game, a program for calculating the ball exit rate, a program for changing the probability of winning a normal symbol lottery based on the calculated ball exit rate, a variable display game and a jackpot execution process. And a program for performing, and is for displaying on the display device 116 a pachinko gaming machine image imitating a pachinko gaming machine, a background image, an image of a variable design, a character image, or the like.

When the game program is executed in the pachinko gaming terminal device 100 or 140, it is detected that the player has operated the input device 102. When it is detected that the player has operated the input device 102, as described above, the pachinko gaming terminal device 100 or 14 is used.
On the display device 116 of 0, a pachinko gaming machine image imitating a pachinko gaming machine is displayed, and the display unit 132 for displaying the variable display game is also displayed on the pachinko gaming machine image.

Furthermore, when the player operates the input device 102 to shoot a game ball, an image of the game ball that can be visually recognized as if the game ball moves on the game board surface is displayed on the pachinko machine image. .

Next, the firing detection number A stored in the RAM 112 and the payout detection number B stored in the RAM 112 are read out, and a process for calculating the ball ejection rate by the above equation (1) is performed (step S33). The frequency of performing the ball-out rate calculation process is not particularly limited, and examples thereof include every 5 minutes and every 10 minutes. The rate is calculated. In step S33, the control unit (CPU 108)
Is functioning as a ball-out rate calculation means for calculating a ball-out rate from the number of game balls hit and the number of game balls paid out.

Next, it is determined whether or not a game ball has entered the winning opening (step S34). This winning opening is an image portion corresponding to the above-described general winning openings 50 and 54a to 54d and special winning openings 56a to 56d shown in FIG.

When it is determined that a game ball has entered the winning opening, a process of paying out a predetermined number of gaming balls according to the type of the winning opening is executed (step S35). In addition, the processing of this step S35, the pachinko game terminal device 1
In 00 or 140, the number of game balls is displayed on the display device 11
The number of game balls may be stored in the RAM 112 even if it is displayed at some position of 6.

Next, it is determined whether or not a game ball has entered the starting opening (step S36). The starting opening is, for example, an image portion corresponding to the starting opening 44 shown in FIG. 2 described above. When it is determined in this step S36 that a game ball has entered the starting opening, a process of paying out a predetermined number of game balls is executed (step S37), and a variable display game described later is executed (step S38). ).
When the process of step S35 or S37 is executed, the control unit 130 (CPU 108) of the pachinko gaming terminal device 100 or 140 determines that one game ball image has been included in the winning opening image, and thus the game is played. It functions as a payout means for paying out a predetermined number of balls.

Next, it is determined whether or not the game ball has passed the ball passage detector (step S39). This sphere passage detector is, for example, the sphere passage detector 55a shown in FIG. 2 described above.
And 55b are image portions.

In this step S39, when it is judged that the game ball has passed the ball passage detector, it is judged whether or not the calculated discharge rate is within a predetermined range based on the upper limit value or the lower limit value. (Step S40). As described above, the above-mentioned ball-out rate is a value based on the ball-out rate calculated and stored at regular time intervals. When it is determined that the rate of departure is within a predetermined range based on the upper limit value or the lower limit value, the following processing is performed. That is, if the exit rate falls within the predetermined range based on the upper limit value, the probability of winning the ordinary symbol lottery is increased, and if it falls within the predetermined range based on the lower limit value, The probability of winning the ordinary symbol lottery is reduced (step S42).

As a method of changing the probability of winning the ordinary symbol lottery, the CPU 108 stores a plurality of probability tables used in the ordinary symbol lottery in the ROM 110,
It is assumed that different probability tables are set in the RAM 110 depending on whether the rate of departure is close to the upper limit value, close to the lower limit value, or far from the upper limit value and the lower limit value.
It is possible to change the probability of winning the normal symbol lottery by using the probability table corresponding to the range of the rate of exit.

Next, the normal symbol lottery process by the calculation process of the CPU 108 is executed (step S43). In this normal symbol lottery process, a lottery is performed with the above-described probability, it is determined whether or not it is won, and the symbols that have been variably displayed are stopped and displayed, and the symbols when the symbols are confirmed are predetermined processes. is there. That is, the CPU 108 uses the RAM 1
In the probability table set to 12, the data corresponding to the numerical values obtained as a result of sampling random numbers is
The result of the lottery. At this time, the control unit functions as an ordinary symbol lottery means for performing an ordinary symbol lottery. Then C
PU108, according to the result of the normal symbol lottery in step S43, in step S44, so that the symbol determined by the normal symbol lottery process is stopped and displayed, after performing the process of displaying the normal symbol in the display device 152 in a variable manner. , Performs stop display processing.

Further, according to the result of the ordinary symbol lottery in step S43, it is determined whether or not the ordinary symbol lottery process is won (step S45). When the normal symbol lottery process is won, the movable pieces 58a and 58b are driven to display a visually recognizable image so that the starting opening 44 is opened, so that the game ball can easily enter the starting opening 44. Yes (step S46).

Next, it is determined whether or not the game is over (step S47). Judgment whether the game is over,
The game is judged to have ended when it is detected that the player has operated the input device 102 to end the game, or when it has been judged that a predetermined number of game balls have been launched onto the game board surface. Of. When it is determined that the game has not ended, the processing is returned to step S32 described above.

On the other hand, when it is determined that the game has ended, a game result indicating the number of game balls shot and the number of game balls refunded, and game end information indicating that the game has ended are transmitted to the server 80. (Step S48), this subroutine is completed.

FIG. 16 is a flow chart showing a subroutine for processing the variable display game called and executed in step S38 of the subroutine shown in FIG. Note that in the flowchart shown in FIG. 16, steps that perform the same processing as the steps in the flowchart shown in FIG.

[0244] First, the information indicating that the variable display game is started by calling this subroutine is sent to the server 8.
0 (step S61). Next, the image of the variable pattern which is the identification information image required in the variable display game, the background image, the image data to be the character image, the control program, and the like are received from the server 80 (step S62). In step S210, which will be described later, the image data and the control program, which are the effect images and the like displayed on the display unit 132 when the jackpot execution process is started and the jackpot state occurs, are stored in this step S6.
In 2, the data is received from the server 80. The image data and the control program used when the jackpot execution process is started may be received from the server 80 when the jackpot execution process is started.

Next, the internal lottery process is executed by the arithmetic process of the CPU 108 of the pachinko gaming terminal device 100 or 140 (step S200). This internal lottery process is a process of predetermining a symbol combination when all symbols belonging to a plurality of variably displayed groups are stopped and displayed and the symbol is fixed, and the CPU 108 executes the internal lottery process as described later. The variable display and the stop display of the symbols are performed so that the symbols are stopped and displayed on the display unit 132 by the combination of the determined symbols.

Next, the CPU 108 executes the above control program, and based on the result, selects the background image, generates the screen configuration information of the background image (step S201), and selects the character image. The screen configuration information of the character image is generated (step S202), and the screen configuration information of the variable symbol that is the identification information is generated (step S203).

Next, among a plurality of sets, for example, three sets, one
It is determined whether it is time to stop and display the symbols belonging to one set (step S204). When it is determined that it is time to stop and display the symbols, one variable symbol is displayed in a stopped manner, and the variable symbol image is selected.
The screen configuration information is generated (step S205).

Then, based on the generated screen configuration information, the necessary image data among the image data received in step S62 is read out and made into the image data to be displayed on the display unit 132, and then displayed. Is displayed on the page (step S206).

By repeating the above-described steps S201 to S206, the normal image including the background image and the character image is displayed on the display unit 132 displayed on the display device 116.

Next, it is determined whether or not all the symbols belonging to the plurality of groups have been stopped and displayed (step S207). When it is determined that all the symbols belonging to the plurality of sets are not stopped and displayed, the process is returned to step S201. On the other hand, in step S207, when it is determined that all the symbols belonging to the plurality of sets are stopped and displayed, the combination of the symbols of the plurality of variable symbols that are stopped and displayed matches the combination of the symbols that are the jackpot state. It is determined whether or not (step S208). However, whether or not a big hit is generated, that is, whether or not the combination of the symbols of the three variable symbols that are stopped and displayed matches the combination of the symbols that are in the big hit state, the internal lottery process in step S200 described above. The result is determined in advance.

In step S208, when it is determined that the combination of the symbols of the plurality of variable symbols that are stopped and displayed matches the combination of the symbols that are in the jackpot state, the jackpot state is set and the jackpot execution process shown in FIG. 17 is performed. The subroutine is executed, and for example, the special winning opening image is in a state of being opened a plurality of times (step S20).
9). On the other hand, in step S208, when it is determined that the combination of the symbols of the plurality of variable symbols that are stopped and displayed does not match the combination of the symbols that are in the big hit state, or when the process of step S209 is executed, the variable display Information indicating that the game is over and result information of the variable display game are transmitted to the server 80 (step S6).
4) Then, this subroutine is finished. It should be noted that the game result information in the jackpot state may be transmitted to the server 80 when the jackpot execution process described later is completed.

FIG. 17 is a flow chart showing a jackpot execution processing subroutine called and executed in step S209 of the variable display game processing routine shown in FIG. Note that in the flowchart shown in FIG. 17, steps that perform the same processing as the steps in the flowchart shown in FIG. In the following description, it is assumed that the jackpot game is provided 15 times intermittently in the jackpot state. Further, the jackpot game is a game that is played once after the special winning opening is opened until 10 game balls enter the special winning opening or until a predetermined time elapses. To do. Furthermore, one jackpot game is also called one round.

In this jackpot execution processing routine, first, the number n of jackpot games is set to n = 1 (step S301). That is, the CPU 108
Causes the table (round number storage table) for storing the number of jackpot games provided in the RAM 112 to store that n = 1.

Next, it is determined whether or not it is time to open the special winning opening image (step S30).
2). When it is determined that it is time to open the special winning opening image, the special winning opening image is displayed in the open state (step S303). This allows the player to insert a game ball into the special winning opening. on the other hand,
When it is determined that it is not the timing when the special winning opening image is in the open state, the process returns to step S302.

Next, it is determined whether or not the game ball image overlaps the special winning opening image (step S304). Then, when it is determined that the game ball image overlaps with the special winning opening image,
The CPU 108 stores the number of game balls in a table (large prize hole game ball storage table) that is provided in the RAM 112 and stores the number of game balls that have entered the special prize hole (step S).
305). Next, a process of paying out a predetermined number of game balls is executed according to the number of game balls entering the special winning opening stored in the special winning opening game ball storage table (step S306). In the process of step S306, in the pachinko gaming terminal device 100 or 140, even if the number of game balls is displayed at some position on the display device 116, the number of game balls is stored in the RAM 112. May be

On the other hand, if it is determined that the game balls do not overlap the special winning opening image, then it is determined whether or not a predetermined number of game balls have entered the special winning opening (step S307).
That is, the CPU 108 compares the number of game balls stored in the special winning hole game ball storage table with a predetermined number of game balls (10 balls) stored in another area of the RAM, and enters the special winning port. It is determined whether the number of game balls is a predetermined number (10 balls).

When it is determined that the predetermined number of game balls has not entered the special winning opening, it is determined whether or not a predetermined time has passed since the special winning opening image was in the open state (step). S308). That is, the CPU 108 determines whether or not the elapsed time count started in step S302 reaches a predetermined time. When it is determined that the predetermined time has not elapsed since the special winning opening image is in the open state, the process is returned to step S304.

On the other hand, when it is determined in step S307 that a predetermined number of game balls have entered the special winning opening, or
When it is determined in step S308 that the predetermined time has elapsed, the special winning opening image is brought into the closed state (step S309). In this way, the opening time of the special winning opening image is determined by either the number of game balls that have entered the special winning opening or the time, and if a predetermined number of game balls enter the special winning opening, a predetermined value is determined. Even if it does not reach the time, the special winning opening image is in a closed state, while if the predetermined time elapses even if the number of game balls entering the special winning opening has not reached a predetermined value, The winning opening image is in a closed state.

Next, 1 is added to n, which is the number of jackpot games, to set n = n + 1 (step S310). That is, the CPU 108 has the RAM 112.
Is stored in the round number storage table provided in (1) so that n = n + 1. And the number of jackpot games n
Is determined to be 15 or less (step S31)
1). That is, the CPU 108 first reads the number of jackpot games stored in the round number storage table, and this number and n = 15 stored in another area of the RAM.
Compared with the data of, the number n of jackpot games is n ≦ 15
Or not. Number of jackpot games n is n ≦
If it is determined to be 15, the process proceeds to step S3.
Return to 02. Therefore, in this subroutine, the jackpot game is repeatedly played until n exceeds 15. On the other hand, when it is determined that n, which is the number of big hit games, exceeds 15, this subroutine is finished.

While the jackpot execution processing routine described above is being executed, the display unit 132 causes the player to recognize that the jackpot state has occurred, and displays an effect image for enlivening the game. .

Further, in the present invention, when the rate of exit is close to the lower limit value, the probability of winning the ordinary symbol lottery is increased to increase the probability that the starting opening will be opened. Therefore, the number of game balls entering the starting port is increased, the probability of a big hit is increased, the probability of receiving a large number of game balls is increased, and the ball exit rate can be increased. On the contrary, when the exit rate falls within a predetermined range based on the upper limit value, it is possible to reduce the exit rate by reducing the probability of winning the ordinary symbol lottery.

According to the present invention, for example, when the numerical value relating to the number of game media falls within a predetermined range based on the lower limit value, the probability of winning the winning lottery is increased to increase the number of game media. Increase the chances of winning the game media, thereby suppressing the decrease of the game media, and conversely, when the number related to the number of game media falls within a predetermined range based on the upper limit, the probability of winning the winning lottery is reduced. As a result, it is possible to reduce the chances that a large number of game media can be acquired, and thereby suppress an increase in the game media. In this way, when the numerical value regarding the number of game media falls within a predetermined range based on the upper limit value or the lower limit value, the probability of winning the winning lottery is changed to adjust the number of game media to be paid out, In order to keep the numerical value related to the number within the range from the upper limit value to the lower limit value, it is possible to omit the inspection such as the ball exit rate performed at the test site.
It is possible to deal with it by only an unannounced inspection. Also, for example, in a pachinko gaming machine, even when the inclination of a plurality of nails planted on the gaming board is adjusted,
By adjusting the number of game balls to be paid out so that the numerical value related to the number of game media falls within the range from the upper limit value to the lower limit value, it rarely exceeds the upper limit value or falls below the lower limit value. Therefore, a healthy game can be provided to the player.

Further, according to the pachinko gaming machine of the present invention as described above, for example, when the exit rate approaches the lower limit, by increasing the probability of winning the normal symbol lottery, the starting opening is opened. The probability of winning a large number of game balls is increased by increasing the probability that it will be suppressed, thereby suppressing the decrease in the ball launch rate, and conversely, when the ball launch rate approaches the upper limit, the probability of winning the ordinary symbol lottery By decreasing, the probability that the starting opening is opened is reduced and the chances that a large number of game balls can be acquired are reduced, thereby suppressing an increase in the ball exit rate. In this way, when the exit rate approaches the upper limit or the lower limit, the probability of winning in the ordinary symbol lottery is changed to adjust the number of game balls paid out per unit time, and the exit rate falls from the upper limit to the lower limit. In order to keep the value within the range up to the value, it is possible to omit the inspection of the ball exit rate or the like performed at the test site, and for example, it is possible to deal with only the spot inspection. In addition, even if the inclination of multiple nails planted on the game board is adjusted, the number of game balls paid out per unit time is adjusted so that the rate of discharge is from the upper limit to the lower limit. Since the value is kept within the range up to the value, the upper limit value is hardly exceeded or the lower limit value is not exceeded, and a sound game can be provided to the player.
