Description

  The present invention relates to a ball game machine that performs an effect in accordance with the result of a winning lottery for determining a winning or losing.

  In the present specification, a pachinko machine is described as an example of a ball game machine, and therefore, a pachinko ball is used as a game ball. However, the game ball includes other spherical media. In addition, it is assumed that a pachinko ball enters a winning opening provided on the game board.

  In a pachinko machine installed in a game hall such as a pachinko parlor, various winning holes, game nails that change the falling direction of the pachinko ball, lamps, and the like are attached to the front of the game board. Then, it is common to change the winning rate of the pachinko ball to the winning opening by adjusting the inclination (opening) of the game nail. The inclination of the game nail is one of the elements for the player to select a pachinko machine where the game is played, and in addition to the inclination of the game nail, the aspect of the effect to be performed is also an element for selecting the pachinko machine. Yes. In addition, adjusting the inclination of the game nail is also important for generating the profit expected by the game hall.

  By the way, a kind of pachinko machine called a digipachi type is known as a kind of pachinko machine. A plurality of game modes such as a normal mode and a winning mode are set for a digital pachinko machine. In the winning mode, a large winning opening that is closed in the normal mode is opened, so that a large amount of pachinko balls can be obtained in a short period of time.

  In such a pachinko machine, a lottery is performed when a pachinko ball wins a start winning opening (start opening) in a game in a normal mode, and in accordance with this, a symbol change display and a stop display are performed. In the winning lottery, either a hit for granting the right to shift to the hit mode or a loss not giving the right to shift to the hit mode is determined. Then, the winning or losing is displayed depending on the type of the symbols that are stopped and the combination of symbols. In recent pachinko machines, in order to have an expectation on the result of the winning lottery, most of the performances are performed when the symbols are displayed in a variable manner. Tend to.

  As an effect, for example, as shown in Patent Document 1, when a symbol that is stopped last is being displayed while the remaining symbols are stopped and displayed, the symbol that is being displayed in a variable manner is stopped and displayed. And the like that are executed in a state where there is a possibility that a win is displayed (hereinafter referred to as a reach state). There are various effects that can be executed in the reach state, such as changing the speed of the variable display of the symbol that is stopped last, or changing the direction in which the symbol of the last stop is variably displayed. In addition, the time when the production is executed varies depending on the type. The type of effect to be executed is determined by lottery. In most pachinko machines, winning probabilities are set so that winning probabilities are high for so-called highly reliable performances with high expectation for winning. For this reason, when a highly reliable performance is executed, the expectation to win is increased, and the player's sense of tension can be increased.

JP 2004-73571 A

  However, in the pachinko machine where the effect is executed as described above, the type of effect to be executed is determined by lottery. For example, if an effect different from the effect that the player likes is frequently executed, I lost interest in the game and sometimes stopped the game. Further, when the type of effect is determined by lottery, the type of effect to be executed may be biased, which has been a factor in making the game monotonous. And these things were factors that led to a loss of profits at the amusement hall due to a decrease in the availability of pachinko machines.

  “Direction” is to suggest (including notification) the result of the lottery that determines the winning or losing, and for example, it may be suggested by a pattern variation pattern, or by voice or light. It may be suggested that the mode can be appropriately set. Examples of the “production execution means” include a liquid crystal panel, a reel having lamps arranged on the outer periphery, a lamp, and a speaker.

  The “start condition” indicates a condition for starting counting the number of winnings, and the “end condition” indicates a condition for finishing counting the number of winnings. The “start condition” and “end condition” indicate that, for example, when a lottery to determine whether or not to start the count is won, the number of times the symbol variation display has been performed has reached a certain number of times, That a certain amount of time has elapsed since the start of sales or the end of the hit mode, that the time that the game has been performed has reached a certain time, that the number of game balls that have been launched has reached a certain number, the first prize A game that has won a certain number of winning game balls in at least one of the mouth and the second winning mouth, and has not won a prize in at least one of the first and second winning mouths The number of balls has reached a certain number, at least one of the first prize opening and the second prize opening, the time that the game ball has not won has reached a certain time, and the game ball is launched for a certain time Inside Is like that was, the conditions can be appropriately set.

  The “winning rate” indicates the number of winning game balls per unit time (for example, one minute) set in advance.

  Further, the bullet ball game machine according to claim 2 is provided with effect lottery means for determining the type of effect to be executed by the effect executing means by lottery.

  Further, in the bullet ball game machine according to claim 3, when the ratio falls below a predetermined ratio set in advance, the effect control means determines that the ratio does not fall below a preset predetermined ratio. A performance that is not executed is executed.

  According to a fourth aspect of the present invention, in the ball game machine according to the fourth aspect, the start condition is that a certain time has elapsed since the power of the ball ball game machine was turned on, and a time during which the game ball does not win the first winning opening is a certain time. At least one of the elapsed times, the end condition is that the number of winnings in the first winning opening reaches a predetermined number. The “certain time” indicates a preset time (for example, one hour), and is preferably set to a time when the game hall starts business. In addition, “a certain period of time after the power is turned on” includes 0 seconds, that is, triggered by the power being turned on.

  In the game machine program of the present invention, a predetermined start condition satisfies the number of winning game balls won in the first winning opening in which a lottery is performed to determine whether or not to win a game ball. The first counting means for counting until a predetermined end condition is satisfied after being played, and the number of winning game balls won in the second winning opening where the lottery is not performed even if the winning game balls are won, A second counting means for counting until the end condition is satisfied after the condition is satisfied; a time counting means for measuring a time required until the end condition is satisfied after the start condition is satisfied; Winning rate calculation means for calculating each winning rate at the first winning port and the second winning port based on the count value of the counting means and the second counting means and the time counted by the time measuring means.

  In addition, the recording medium of the present invention is configured so that the number of winning game balls won in the first winning opening where a lottery for determining or losing a game ball is made is satisfied after a predetermined start condition is satisfied. The first condition means that counts until a preset end condition is satisfied, and the start condition satisfies the number of winning game balls won in the second winning opening where the lottery is not performed even if a game ball wins. A second counting means for counting until the end condition is satisfied, a time counting means for measuring a time required for the end condition to be satisfied after the start condition is satisfied, the first count means, A winning rate calculating means for calculating each winning rate at the first winning port and the second winning port based on the count value of the second counting unit and the time counted by the timing unit; A winning ratio calculating means for calculating a ratio of a winning rate at the second winning port with respect to a winning rate at a winning mouth, and an effect corresponding to a plurality of types of effects executed in accordance with the lottery result, which are different from each other. The effect storage means for storing the data and the effect data to be read from the effect storage means are determined depending on whether or not the ratio exceeds a predetermined ratio set in advance, and the effect execution means is determined based on the read effect data. The computer-readable recording medium stores a program that causes the computer of the gaming machine to function as an effect control means for executing the effect.

  The effect to be executed is determined depending on whether or not the ratio of the winning rate at the second winning port with respect to the winning rate at the first winning port exceeds a predetermined ratio set in advance. It is possible to reflect the player's preference without depending on the player, and to increase the player's interest in the production.

  In addition, since the type of effect to be executed is determined by lottery, the type of effect can be varied and the game can be prevented from becoming monotonous.

  In addition, when the ratio falls below a predetermined ratio set in advance, an effect that is not executed when the ratio does not fall below the preset predetermined ratio is executed, so that the game ball wins the first winning opening. By adjusting the game nails to make it easier to play, it becomes possible to increase the variety of types of productions, increase the chances of lottery to determine winning or losing, and enhance the player's interest in games it can.

  Also, the start condition for counting the number of winnings at the first winning opening and the second winning opening is that a certain time has elapsed since the power of the ball game machine was turned on, and the gaming ball does not win the first winning opening. Since at least one of the predetermined time has elapsed, it is possible to start counting together with the game hall business start time, and to calculate the winning rate more accurately. In addition, as a condition for ending counting the number of winnings at the first winning port and the second winning port, the number of winnings at the first winning port has reached a predetermined number. It is possible to calculate the winning rate after a sufficient winning is obtained, and the winning rate can be calculated more accurately.

  The pachinko machine 10 is provided with two game modes, a normal mode and a winning mode. In the winning mode, the special winning opening 17 that is closed in the normal mode is opened. In the single hit mode, the grand prize opening 17 is opened 15 times, and the big prize opening 17 is opened until, for example, 30 seconds elapse for each opening or ten pachinko balls are won. The When winning in the winning lottery, the mode is changed to the winning mode.

  Next, the configuration of the pachinko machine 10 will be described. A symbol display device (production execution means) 12 is incorporated in the game board surface 11 a of the game board 11 of the pachinko machine 10. The game area in front of the game board surface 11a is provided with a start port (first winning port) 13, a normal port (second winning port) 14, a rotary door 15, and an out port 16, and a plurality of game nails. 11b is provided.

  The game nail 11b is driven into the game board surface 11a. The falling direction of the pachinko ball falling in the game area is changed by the game nail 11b. The game nail 11b is driven into the game board surface 11a so that the inclination of the game nail 11b can be adjusted when an external force is applied to the tip of the game nail 11b, for example. Then, for example, by adjusting the inclination of the game nail 11b outside the game hall business hours, the winning rate of the pachinko balls to the starting port 13 and the normal port 14 (the number of pachinko balls won per unit time) is adjusted. The In the present embodiment, the “unit time” for calculating the winning rate is calculated as 1 minute.

  A launch handle 10 a is provided on the front surface of the pachinko machine 10. When the firing handle 10a is operated, the pachinko balls are launched one by one into the game area in front of the game board surface 11a by the firing control device. The hit pachinko ball wins either the start port 13 or the normal port 14 or enters the out port 16. When a pachinko ball wins at the start port 13, the winning ball is paid out and a lottery is performed. When a pachinko ball wins in the normal mouth 14, a winning lottery is not performed and only award ball is paid out. Pachinko balls that have entered the out mouth 16 are collected as out balls.

  A big prize opening 17 is provided at the back of the rotary door 15. The pivot door 15 is attached so as to be rotatable between an open position where the big prize opening 17 is opened and a closed position where the big prize opening 17 is closed. In the normal mode, the pivot door 15 is located at the closed position, and when the transition is made to the hit mode, the pivot door 15 is pivoted to the open position. As a result, the special winning opening 17 is opened in the winning mode.

  A liquid crystal panel 18 is incorporated in the symbol display device 12. The liquid crystal panel 18 displays three symbols arranged in parallel. The symbols are composed of 10 types of symbols indicating the numbers “0” to “9”. When the pachinko ball wins the start opening 13, the variation display of the symbols in each column is started. Then, depending on the combination of symbols when the symbols are stopped and displayed, it is displayed whether the winning lottery result is winning or losing. If three of the same numbers are collected, it is a win, and other combinations are lost. In the pachinko machine 10, the design is variably displayed by any one of a plurality of types of variation patterns having different aspects.

  As shown in FIG. 2, the pachinko machine 10 includes a main control unit 30 and a sub control unit 31. The main control unit 30 is provided with a main control device 32. The operation of the pachinko machine 10 is controlled by a CPU 33 provided in the main control device 32.

  In addition to the CPU 33, the main controller 32 includes a memory 34, a hit determination unit 35, a stop symbol determination unit 36, a first count unit (first count unit) 37, a second count unit (second count unit) 38, and a prize. A rate calculating section (winning rate calculating means) 39a, a winning ratio calculating section (winning ratio calculating means) 39b, a timer 40, and the like are provided. In response to the power switch (power SW) 10b being turned on, the CPU 33 starts control of the operation of the pachinko machine 10 according to the program stored in the ROM area of the memory 34.

  The winning determination unit 35 performs a lottery every time a pachinko ball is detected at the start port 13. The hit determination unit 35 includes a random number generator, a random number sampling circuit, and a hit determination table. In the random number generator, the random number value is updated by incrementing the random number value within a predetermined range at regular intervals. Then, a random number sampling circuit extracts a random number value updated when a starting port sensor 41 described later detects a pachinko ball, and collates the extracted random value with a hit determination table.

  In the winning determination table, one of two types of winning and losing is assigned to all random numbers generated by the random number generator. Then, either the winning or losing is determined depending on whether the extracted random number value is a winning random number assigned with winning or a losing random number assigned with losing.

  For example, all random numbers generated by a random number generator are divided into two numerical ranges in advance, and the divided two numerical ranges are assigned or lost, and the extracted random values are values belonging to any numerical range. An appropriate method may be used as the winning lottery method, such as determining whether to win or lose depending on whether there is any. In addition, for example, the normal perm that grants only the right to shift to the hit mode and the right to shift to the probability variation mode in which the probability of shifting to the hit mode is higher than the normal mode in addition to the right to shift to the hit mode are granted. The winning mode determined by the winning lottery may be set as appropriate, such as determining the winning per winning variation, and determining the normal winning, the probable variation, or the loss by winning the lottery.

  The stop symbol determination unit 36 determines a combination of symbols to be stopped and displayed on the liquid crystal panel 18 (stop symbol). The stop symbol determination unit 36 includes a random number generator, a random number sampling circuit, and a stop symbol table, and is operated after the winning lottery. When the lottery in the stop symbol determination unit 36 is completed, a signal indicating the determined symbol combination is input from the CPU 33 to the symbol display control device 45 described later.

  The first counting unit 37 counts the number of winning pachinko balls at the start port 13, and the second counting unit 38 counts the number of winning pachinko balls at the normal port 14. The CPU 33 inputs a detection signal to the first count unit 37 every time a pachinko ball is detected at the start port 13, and sends a detection signal to the second count unit 38 every time a pachinko ball is detected at the normal port 14. input. The first count unit 37 and the second count unit 38 increment each count value every time a detection signal is input. As a result, the number of winning pachinko balls at the start port 13 and the normal port 14 is counted.

  When the power switch 10b is turned on or when the time when no winning is generated at the start port 13 reaches one hour, the CPU 33 activates the timer 40. Then, the first count unit 37 and the second count unit 38 are operated when the time of the timer 40 has elapsed (start condition). For this reason, if the power switch 10b is turned on one hour before the game hall business start time, the counting at the counting units 37 and 38 can be started at the same time as the business start. When the time of the timer 40 reaches 1 hour, the CPU 33 resets the time of the timer 40 and continues to measure time. Although not shown in detail, it is provided separately from the timer 40 that measures the time during which no winning is generated at the start port 13.

  Then, when the number of pachinko balls that have won the start opening 13 reaches, for example, 200 (predetermined number), that is, when the count value in the first count unit 37 reaches 200, the CPU 33 37, the operation of the second count unit 38, and the timer 40 are stopped. The count values of the count units 37 and 38 are cleared when the power switch 10b is turned on again.

  The winning rate calculation unit 39a is activated when the operations of the counting units 37 and 38 are stopped. The winning rate calculation unit 39a receives the count value in each of the counting units 37 and 38 and the time counted by the timer 40. Based on this, in the winning rate calculation unit 39a, the count value in each of the counting units 37 and 38 is divided by the time in the timer 40. Thereby, the winning rate in each count part 37 and 38 is calculated.

  The winning rate calculating unit 39b is operated after the winning rate calculating unit 39a finishes calculating the winning rate. The CPU 33 inputs the winning rate of each of the counting units 37 and 38 calculated by the winning rate calculating unit 39a to the winning rate calculating unit 39b. In the winning rate calculation unit 39b, the ratio of the winning rate of the normal port 14 to the winning rate of the start port 13 is calculated based on each input winning rate. This ratio is calculated by dividing the winning rate of the normal port 14 by the winning rate of the start port 13. The CPU 33 determines whether or not the calculated winning rate ratio has exceeded 1/10.

  The CPU 33 is connected to each sensor provided in the main control unit 30 such as the start port sensor 41, the big prize port sensor 42, the normal port sensor 43, and the payout port sensor 44, and a pachinko ball detection signal is input from each sensor. Is done. Further, the CPU 33 includes each device of the sub-control unit 31 such as the symbol display control device 45, the lamp control device 46, and the voice control device 47, and each device of the main control unit 32 such as the payout control device 48 and the movable member control device 49. Is connected. Further, a launch control device 49 is provided in the main control unit 30.

  The start opening sensor 41, the start opening 13 and the big winning opening sensor 42 detect whether or not the pachinko ball has won the normal opening 14 in the big winning opening 17 and the normal opening sensor 43, respectively. The payout sensor 44 detects whether the pachinko ball has been paid out.

  The symbol display control device 45 includes a display CPU (effect control means) 55, a variation pattern lottery section (effect lottery means) 56, and a variation pattern memory (effect storage means) 57.

  The display CPU 55 performs display control of an image displayed from the liquid crystal panel 18. The display CPU 55 identifies which symbol is displayed from the liquid crystal panel 18 by monitoring the head address assigned to each symbol displayed on the liquid crystal panel 18. Thereby, the change display and stop display of a symbol are performed. The result of the lottery in the stop symbol determination unit 36 is input from the CPU 33 to the display CPU 55. The display CPU 55 stops the symbols that are changed so that the combination of symbols determined by the stop symbol determination unit 36 is displayed.

  The variation pattern lottery unit 56 performs variation lottery, and determines which of the plurality of types of variation patterns is used for the symbol variation display. The variation pattern lottery unit 56 includes a variation determination table 58.

  A plurality of types of variation patterns having different aspects are assigned to the variation determination table 58. For example, three types of variation patterns of variation pattern “A”, variation pattern “B”, and variation pattern “C” are assigned to the variation determination table. Then, either the variation pattern “A” or the variation pattern “B” is determined according to the ratio calculated by the winning ratio calculation unit 39b (effect mode A), or the variation patterns “A” to “C”. "Is determined (direction mode B). Note that changing the type of fluctuation pattern using one type of fluctuation determination table 58 can be realized by taking appropriate measures such as changing the number of random numbers generated when collating with the fluctuation determination table 58, for example. It is.

  The variation pattern memory 57 stores graphic data for displaying an image from the liquid crystal panel 18. The display CPU 55 reads the graphic data of the fluctuation pattern memory 57 and causes the liquid crystal panel 18 to perform the fluctuation display and stop display of the symbols. The variation pattern memory 57 also stores graphic data corresponding to the variation pattern assigned to the variation determination table 58. Thereby, the change display of a symbol is performed by the change pattern determined by the change lottery.

  The lamp control device 46 performs lighting control of various lamps provided in the pachinko machine 10 according to the state of the game, for example, blinking the lamp in the hit mode.

  The sound control device 47 includes a sound memory, reads a sound program obtained by programming music and sound from the sound memory, and outputs music and sound from a speaker via a sound processor. As a result, music or voice is output from the speaker according to the state of the game, such as when changing the symbol display or shifting to the hit mode.

  The payout control device 48 is activated when any of the start port sensor 41, the big prize port sensor 42, and the normal port sensor 43 detects a pachinko ball. The payout control device 48 includes a memory, and in this memory, a payout table is stored in which the number of pachinko balls to be paid out for a single pachinko ball winning is associated with the type of winning opening. The payout control device 48 drives a storage device in which payout pachinko balls are stored, and causes the number of pachinko balls to be paid out according to the type of winning opening. The pachinko ball may be paid out to the player when the pachinko ball is detected at the normal port 14.

  The movable member control device 49 is connected to a solenoid (not shown) that drives the rotary door 15. The movable member control device 49 controls the driving of the solenoid in the hit mode, and rotates the rotating door 15 between the open position and the closed position.

  The launch control device 49 is connected to the launch handle 10a, and launches the pachinko ball at regular intervals according to the launch strength of the pachinko ball adjusted by the launch handle 10a.

  Next, the operation of the pachinko machine 10 configured as described above will be described. As shown in FIG. 3, for example, when an employee turns on the pachinko machine 10 with the power switch 10b one hour before the game hall business start time, the CPU 33 activates the timer 40 in response to turning on the power. . Thereafter, the CPU 33 monitors the time of the timer 40 and determines whether one hour has elapsed since the power switch 10b was turned on.

  When one hour elapses after the power switch 10b is turned on, that is, when the game hall business start time comes, the CPU 33 activates the first count unit 37 and the second count unit 38. As a result, the number of pachinko balls won at each of the start port 13 and the normal port 14 is counted. The time of the timer 40 is reset and time is continuously measured.

  In the pachinko machine 10, a game in the normal mode and the effect mode A is first performed. When the player operates the firing handle 10a, a pachinko ball launched into any of the start port 13, the normal port 14, and the out port 16 enters. When a pachinko ball wins at the start port 13, a winning lottery is performed by the hit determining unit 35, and a win or a loss is determined. When the winning lottery is completed, the stop symbol determining unit 36 is operated, and the combination of stop symbols is determined by lottery on the liquid crystal panel 18. Thereafter, a stop symbol is transmitted from the CPU 33 to the display CPU 55. When the stop symbol is received, the display CPU 55 operates the variation pattern lottery unit 56. The variation pattern lottery unit 56 performs a variation lottery to determine a variation pattern for displaying a symbol variation.

  At this time, since the mode is shifted to the production mode A, either the variation pattern “A” or “B” is determined. When the variation lottery is completed, the display CPU 55 reads the graphic data from the variation pattern memory 57 and starts the variation display of the symbols. When winning in the winning lottery, the winning symbol is displayed by the stop symbol, and the normal mode is shifted to the winning mode. If the winning lottery is lost, the lost symbol is displayed according to the stop symbol, and the game in the normal mode is continued.

  The CPU 33 monitors the number of pachinko balls won in the start port 13 in the first count unit 37 after the first count unit 37 and the second count unit 38 start counting the number of winnings. Then, the CPU 33 determines whether or not this number has reached 200. When the number of pachinko balls winning in the start port 13 reaches 200, the CPU 33 stops the operation of the first count unit 37, the second count unit 38, and the timer 40. Then, the count value in each count unit 37, 38 and the time counted by the timer 40 are input to the winning rate calculation unit 39a. In the winning rate calculation unit 39a, the winning rates in the counting units 37 and 38 are calculated. When the calculation of the winning rate is completed, the winning rate calculating unit 39b calculates the ratio of the winning rate of the normal port 14 to the winning rate of the starting port 13.

  When the winning rate ratio is calculated, the CPU 33 determines whether or not the calculated ratio exceeds 1/10, that is, whether or not the winning rate of the normal port 14 exceeds 1/10 of the winning rate of the start port 13. Determine whether. As a result of the determination, when the calculated ratio is less than 1/10, that is, when the winning rate of the normal port 14 is lower than 1/10 of the winning rate of the starting port 13, the CPU 33 shifts to the effect mode B. A signal indicating that this is to be input is input to the display CPU 55. As a result of the determination, if this ratio is not less than 1/10, that is, if the winning rate of the normal port 14 is not less than 1/10 of the winning rate of the start port 13, the CPU 33 performs the effect mode A. A signal indicating the transition to is input to the display CPU 55.

  These signals are input from the display CPU 55 to the effect pattern lottery unit 56. In the case of the production mode A, the production pattern lottery unit 56 determines one of the two types of variation patterns when a winning occurs at the start port 13 in the subsequent games. In the case of the production mode B, the production pattern lottery unit 56 determines one of the three types of variation patterns when a winning is generated at the start port 13 in the subsequent games. As a result, the type of variation pattern changes depending on the winning rate ratio between the start port 13 and the normal port 14.

  When the game hall is closed and the power switch 10b is turned off, the count values of the first count unit 37 and the second count unit 38 are cleared when the power switch 10b is turned on again. Operation is performed. Although the above operation has been described by taking the case where the power switch 10b is turned on as an example, the same processing is performed when the time when no winning is generated at the start port 13 has reached one hour.

  FIG. 4 shows an example in which a recording medium (CD, flexible disk, IC memory, MO, etc.) 60 is installed in the slot machine 10, and the means shown in the flowchart of FIG. 34, and a program to be realized by the computer 61 is stored. In this case, for example, the number of game balls won in the first winning opening where a lottery for determining or losing a game ball is performed is set as an end after a preset start condition is satisfied. A first counting means for counting until the condition is satisfied, and the number of game balls won in the second winning opening where the lottery is not performed even if a game ball wins, and the end after the start condition is satisfied Second counting means for counting until the condition is satisfied, time measuring means for measuring the time taken from when the start condition is satisfied until the end condition is satisfied, the first counting means and the second counting means Winning rate calculation means for calculating each winning rate at the first winning port and the second winning port based on the count value at the time and the time counted by the timing means, and at the first winning port The winning percentage calculating means for calculating the ratio of the winning percentage at the second winning opening with respect to the winning percentage is different from the aspect and stores the effect data corresponding to the plurality of kinds of effects executed according to the result of the lottery. The effect storage means and the effect data to be read from the effect storage means are determined depending on whether or not the ratio exceeds a predetermined ratio set in advance, and the effect execution means is caused to execute the effect based on the read effect data. A program for causing the computer 61 to function as effect control means is recorded on the recording medium 60. Then, the recording medium 60 is loaded into the reading device 62 and the program is installed in the slot machine 10.

  The program can be distributed to the slot machine 10 using the Internet instead of being installed via the recording medium 60. It is also possible to install the distributed program of the present invention or the program of the present invention read from the recording medium 60 in a personal computer and play a slot machine game on a monitor.

  In the above embodiment, the effect mode A and the effect mode B are switched using one type of change determination table 58, but a change determination table used in each effect mode may be provided separately. In addition, description is abbreviate | omitted about the function part which has the function similar to the said embodiment, and description is abbreviate | omitted about the part similar to the said embodiment also about the flow of a game.

  When providing a plurality of change determination tables, for example, as shown in FIG. 5, the change pattern lottery unit 70 may be provided with a first change determination table 71 and a second change determination table 72. The first variation determination table 71 and the second variation determination table 72 are assigned the same number of different variation patterns. Then, as shown in FIG. 6, when the ratio calculated by the winning ratio calculation unit 39b is less than 1/10, the display CPU 55 displays a signal indicating that the mode is shifted to the effect mode B. 70 makes the fluctuation lottery using the second fluctuation determination table 72. Further, if the ratio calculated by the winning ratio calculation unit 39b is not less than 1/10, the display CPU 55 sends a signal indicating the transition to the effect mode A to the variation pattern lottery unit 70 to determine the first variation. A variable lottery is performed using the table 72. In addition, you may set suitably the aspect of the variation pattern allocated to the 1st variation determination table 71 and the 2nd variation determination table 72, and the number thereof.

  In the above embodiment, a pachinko machine has been described as an example of a ball game machine, but the present invention can also be applied to other ball game machines as long as an effect is executed according to the result of a lottery.

It is an external appearance perspective view of a pachinko machine. It is a functional block diagram which shows the electrical structure of a pachinko machine. It is a flowchart which shows the flow of a game. It is explanatory drawing in the case of installing the recording medium in which the program was stored in the pachinko machine. It is a functional block diagram showing an electrical configuration when a plurality of variation determination tables are provided. It is a flowchart which shows the flow of the game at the time of providing multiple variation determination tables.
