Description

  According to the present invention, a lottery for determining whether or not to move a movable member that widens a region where a game ball wins a prize is performed, and the result of the lottery is notified according to the type of the normal symbol that is stopped and displayed. It relates to a ball game machine.

  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.

  A pachinko machine used in a game hall such as a pachinko parlor is given a certain value to a pachinko ball, and the pachinko ball acquired by playing a game can be exchanged for various prizes. For this reason, the main purpose of the player is to acquire a large amount of pachinko balls, and it is one of the pleasures to play a game in a game mode in which a large amount of pachinko balls can be acquired in a short period of time.

  As a kind of pachinko machine, a kind of pachinko machine called a digipachi type is known. Some digipachi type pachinko machines have a game mode such as a normal mode or a hit mode.

  In the winning mode, a rotatable attacker (rotating door) rotates between a closed position for closing the grand prize opening and an open position for opening the big prize opening, and the big prize opening closed in the normal mode is opened. Is done. One opening of the grand prize opening, that is, one round is continued until, for example, the grand prize opening is opened for 30 seconds or ten pachinko balls are won in the big prize opening. Since the big winning opening is opened in the winning mode, more pachinko balls can be obtained than in the normal mode.

  In the pachinko machine as described above, generally, when a pachinko ball wins at the starting port in a game in the normal mode, a winning lottery is performed and a special symbol is displayed in a variable manner. Then, according to the combination of the special symbols that are stopped and displayed, it is displayed whether the winning lottery result is a winning or a lost. When winning is displayed, the mode is changed to winning mode.

  Some recent pachinko machines have a game mode called a time reduction mode in addition to the normal mode and the winning mode. In general, the short-time mode is continuously shifted to the hit mode. In the time reduction mode, the time for changing the symbol display (variation time) is shorter than in the normal mode. Most pachinko machines in which the time reduction mode is set are provided with a pair of movable members as shown in Patent Document 1, for example, at the start port. When the movable member is moved, the area where the pachinko ball wins the starting opening becomes wide.

Whether or not the movable member is movable is determined by an open lottery performed separately from the winning lottery. The open lottery is performed when a pachinko ball is detected at a passing port (a gate through which the pachinko ball passes) which is different from the starting port. The result of the open lottery is notified by a change display and a stop display of a normal symbol provided separately from the special symbol. In the time reduction mode, the time during which the movable member is located at the open position is longer than in the normal mode. For this reason, in the short time mode, it is easy to win a pachinko ball at the starting port. As a result, in the time reduction mode, the symbol variation display can be performed continuously, and the symbol variation time is shortened, so that the game can be performed efficiently. In the short time mode, a pachinko ball can be easily won at the starting port, so that a game can be played with the prize ball, and a game can be played without reducing the number of pachinko balls. Thereby, it is possible to prevent the player from stopping the game immediately after the hit mode ends, and to prevent the operation rate of the pachinko machine from decreasing.

  By the way, conventionally, the variation time of the normal symbol has been set to be constant regardless of the type of game mode. For this reason, most players stop launching pachinko balls in the short-time mode until the result of the open lottery is displayed, and only when the winning lot is widened by winning the open lottery, A so-called stop-off is performed. The player who performs the stop hitting detects the pachinko ball at the passage after the end of the movement of the movable member, and stops the launch of the pachinko ball again. This prevents the player from using the pachinko ball in vain during the time-saving mode. However, this led to a decrease in the operating rate of pachinko machines and a loss of profits at the amusement hall.

  For this reason, in the short-time mode, it is considered that the winning probability of the open lottery is made higher than in other game modes, and accordingly, the fluctuation time of the normal symbol is shortened. However, in the winning mode, the open lottery is performed in a state where the winning probability is low. Therefore, when shifting from the winning mode to the time-saving mode during the normal symbol variation display, the normal symbol changes to the time-saving mode with a long variation time. In this case, since it becomes impossible to predict the time until the normal symbol stops after shifting to the time reduction mode, the player must continue to launch the pachinko ball after shifting to the time reduction mode. It is necessary to come out. And this may be a factor that lowers the interest of the player in the game.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a bullet ball gaming machine capable of preventing a player from unnecessarily hitting a game ball.

  In the ball game machine of the present invention, a lottery is performed to determine whether or not to move a movable member that widens an area where a game ball wins a winning opening, and the result of the lottery depends on the type of the normal symbol that is stopped and displayed. In the ball game machine in which is notified, a plurality of types of lottery tables used in the lottery and having different winning probabilities in the lottery and the lottery table used in the lottery when a predetermined game condition is satisfied Table selection means for switching, display control means for shortening the fluctuation time of the normal symbol as the winning probability in the lottery table used in the lottery increases, and the winning probability being low during the fluctuation display of the normal symbol Fluctuating time notifying means for notifying the time until the normal symbol in the variable display is stopped and displayed when the lottery table is switched to the lottery table having a high winning probability. It is intended to provide.

  In addition, special symbol display means for informing whether or not it is hit by a change display and a stop display of a special symbol provided separately from the normal symbol, a normal mode, and a winning opening that is closed in the normal mode A game control means for executing a game in a winning mode that is released and a time-saving mode in which the transition time of the special symbol is shorter than that in the normal mode, and two types having different winning probabilities The lottery table, wherein the table selection means performs the lottery using the lottery table with the low winning probability in the normal mode and the winning mode, and the lottery with the high winning probability in the short-time mode. The lottery is preferably performed using a table.

  Further, the program of the present invention includes a table selection means for switching a lottery table used in a lottery for determining whether or not to move a movable member that widens a region where a game ball wins a winning opening, and the above-mentioned lottery used in the lottery As the winning probability in the lottery table increases, the display control means for shortening the variation time of the normal symbol for notifying the lottery result, and the winning probability from the lottery table having a low winning probability during the variation display of the normal symbol. When switched to the high lottery table, the computer of the gaming machine is made to function as a fluctuating time notifying means for notifying the time until the normal symbol in the fluctuating display is stopped and displayed.

  The recording medium of the present invention was used in the lottery table selection means for switching a lottery table used in a lottery to determine whether or not to move a movable member that widens a region where a game ball wins a winning opening. The higher the winning probability in the lottery table, the shorter the variation time of the normal symbol for notifying the result of the lottery, and the winning probability from the lottery table with the low probability of winning during the variation display of the normal symbol A computer-readable recording medium storing a program for causing a computer of a gaming machine to function as a changing time notifying means for notifying a time until a normal symbol being changed and displayed is stopped and displayed when the lottery table is changed to a higher one It is.

  When switching from a lottery table with a low open lottery winning probability to a lottery table with a high open lottery winning probability during normal symbol fluctuation display, the time until the normal symbol in the variable display is stopped is displayed. Therefore, it is only necessary to prepare for launching a game ball in accordance with the timing at which the normal symbol stops, and it is possible to prevent the player from launching the game ball in vain. Thereby, it becomes possible to take a break with the notified time as a guide, and fatigue during the game can be alleviated.

  In the normal mode and the winning mode, the open lottery is performed using the lottery table having a low open lottery winning probability, and in the short time mode, the open lottery is performed using the lottery table having a high open lottery winning probability. Then, it becomes possible to shorten the fluctuation time of the normal symbol as compared with the normal mode and the hit mode, and it is possible to increase the game efficiency in the short-time mode. Thereby, it can prevent that the operation rate of a ball game machine falls, and can prevent the loss of the profit of a game hall.

  The pachinko machine 10 is provided with three game modes: a normal mode, a winning mode, and a time reduction mode. When a pachinko ball wins at the start port 13, a winning lottery for determining a winning or losing is performed. When winning in the winning lottery, the winning mode is followed by the short time mode. The result of the winning lottery is displayed with a special symbol. In the winning mode, the special winning opening 17 that is closed in the normal mode is opened. In the winning mode, the special winning opening 17 is opened 15 times. The big winning opening 17 is opened (one round) until, for example, 30 seconds elapses or until ten pachinko balls are won. In the time reduction mode, the variation time of the special symbol is shorter than that in the normal mode, and as will be described in detail later, it is easier for the pachinko ball to win the start opening 13.

  Next, the configuration of the pachinko machine 10 will be described. A symbol display device 12 is incorporated in the game board surface 11 a of the game board 11 of the pachinko machine 10. In addition, the game board surface 11a is provided with a start port (winning port) 13, a passage port 14, an attacker 15, and an out port 16. Further, although not shown in the drawing, a obstacle nail, a windmill, and the like are provided. 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 the start opening 13, passes the passing opening 14, or enters the out opening 16. The pachinko balls that have entered the out mouth 16 are recovered as lost balls.

  A big prize opening 17 is provided in the back of the attacker 15. The attacker 15 is attached so as to be rotatable between an open position where the special winning opening 17 is opened and a closed position where the special winning opening 17 is closed. In the normal mode, the attacker 15 is located at the closed position, and when the mode is shifted to the hit mode, the attacker 15 rotates to the open position.

  The start port 13 is provided with a pair of movable members 13a so as to face each other. The movable member 13a has a vertical cross-sectional shape that is substantially arcuate, and the planes of the movable member 13a face each other. The movable member 13a rotates between a closed position where the movable members 13a face each other and an open position where the tip ends away from each other. The movable member 13a is moved when an open lottery for determining whether or not to rotate the movable member 13a from the closed position to the open position is won. The open lottery is performed when a pachinko ball passes through the passage opening 14. When the movable member 13a is located at the open position, the area where the pachinko ball wins the starting port 13 becomes wider than when the movable member 13a is located at the closed position. Note that the pitch between the movable members 13a is set so that a pachinko ball can be won at the start port 13 even when the movable member 13a is located at the closed position.

  A liquid crystal panel (fluctuation time notification means and special symbol display means) 18 is incorporated in the central portion of the symbol display device 12. Three special symbols are displayed in parallel on the liquid crystal panel 18. From the liquid crystal panel 18, ten kinds of special symbols indicating the numbers “0” to “9” are displayed in each column. When a pachinko ball wins at the start port 13, special symbols in each row are displayed in a variable manner. Then, depending on the combination of symbols when the special symbol is stopped and displayed, it is displayed whether the winning lottery result is a winning or a loss. When three special symbols of the same type are arranged, it is a win, and other combinations are lost.

  A normal symbol display 19 composed of, for example, a 7-segment display is incorporated in front of the symbol display device 12 and above it. The normal symbol display 19 displays ten types of normal symbols composed of “0” to “9” indicating numbers. When the pachinko ball passes through the passage opening 14, the normal symbol variation display is started. When the normal symbol is stopped and displayed, if the normal symbol indicating the odd number (odd symbol) stops, it is displayed that the open lottery is won, and if the even symbol indicating the even number is stopped, it is displayed that the open lottery is lost. Is done.

  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 (table selection means, game control means and display control means) 33 provided in the main control device 32.

  In addition to the CPU 33, the main control device 32 includes a memory 34, a hit determination unit 35, a special symbol determination unit 36a, a normal symbol determination unit 36b, an open lottery unit 37, a timer 38, and the like. The CPU 33 controls the operation of the pachinko machine 10 in accordance with a program stored in the ROM area of the memory 34 to execute a game.

  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, the random number sampling circuit extracts a random number value updated when a starting port sensor 40 described later detects a pachinko ball, and compares 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. In this case, in the probability variation mode, the winning probability of winning may be higher than that in the normal mode, and the variation time of the special symbol may be shorter than that in the normal mode.

  In the special symbol determination unit 36a, a combination of special symbols to be stopped and displayed on the liquid crystal panel 18 is determined by lottery. The special symbol determination unit 36a is operated after the winning lottery is completed. The special symbol determination unit 36a includes a table that is used when winning in the winning lottery and a table that is used when winning in the winning lottery. When the lottery at the special symbol determination unit 36a is completed, a signal indicating the determined combination of special symbols is input from the CPU 33 to the symbol display control device 44 described later.

  In the normal symbol determination unit 36b, the type of the normal symbol to be stopped and displayed from the normal symbol display 19 is determined by lottery. The normal symbol determination unit 36b is operated after the open lottery is completed. The normal symbol determination unit 36b includes a table that is used when the open lottery is won and a table that is used when the open lottery is lost. When the lottery in the normal symbol determination unit 36b is completed, a signal indicating the determined type of the normal symbol is input from the CPU 33 to the symbol display control device 44 described later.

  The opening lottery unit 37 is activated when a pachinko ball is detected at the passage port 14. The open lottery unit 37 performs an open lottery to determine whether or not the movable member 13a is rotated from the closed position to the open position. The open lottery section 37 is connected to a first lottery table (lottery table) 37a and a second lottery table (lottery table) 37b. The open lottery section 37 identifies whether to perform an open lottery using any table in response to a table selection signal input from the CPU 33. When the CPU 33 detects that the pachinko ball has passed through the passage port 14 in the normal mode and the hit mode, the CPU 33 detects that the pachinko ball has passed through the passage port 14 in the time reduction mode. A table selection signal using the 2 lottery table 37 b is input to the open lottery unit 37. The open lottery section 37 determines whether or not the open lottery has been won by comparing the random number value that has been drawn with the first lottery table 37a or the second lottery table 37b. The first lottery table 37a and the second lottery table 37b have different winning probabilities in the open lottery, and the second lottery table 37b is won so that the winning probability is higher than the first lottery table 37a. The number of random numbers is increasing. The result of the open lottery is fed back to the CPU 33. In this way, the first lottery table 37a is used in the normal mode and the winning mode, and the second lottery table 37b is used in the time reduction mode. Then, the mode is shifted from the hit mode to the time reduction mode, and the mode is changed from the time reduction mode to the normal mode or the hit mode.

  The timer 38 is usually activated when the symbol variation starts. The CPU 33 inputs a variation start signal indicating the start of variation of the normal symbol to the symbol display control device 44 along with the operation of the timer 38. Then, the CPU 33 monitors the count value of the timer 38, and indicates that when the open lottery is performed using the first lottery table 37a, the normal symbol is stopped and displayed after 30 seconds from the start of the variation of the normal symbol. The signal is input to the symbol display control device 44. Thus, in the normal mode and the hit mode, the normal symbol is stopped and displayed after the fluctuation display for 30 seconds. In addition, when the open lottery is performed using the second lottery table 37b, the CPU 33 inputs a stop signal to the symbol display control device 44 after 5 seconds from the start of the normal symbol fluctuation. As a result, in the time reduction mode, the normal symbol is stopped and displayed after the fluctuation display for 5 seconds. The count value of the timer 38 is reset by the CPU 33 together with the transmission of the stop signal.

  The CPU 33 is connected with each sensor provided in the main control unit 30 such as the start port sensor 40, the big prize port sensor 41, the passing port sensor 42, the payout port sensor 43, and the detection signal of the pachinko ball 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 44, the lamp control device 45, and the voice control device 46, and each device of the main control unit 32 such as the payout control device 47 and the movable member control device 48. Is connected. Further, a launch control device 49 is provided in the main control unit 30.

  The starting port sensor 40 detects the pachinko ball at the starting port 13, the big winning port sensor 41 detects the big winning port 17, and the passing port sensor 42 detects whether the pachinko ball is detected at the passing port 14. The payout sensor 43 detects whether or not the pachinko ball has been paid out.

  The symbol display control device 44 includes a display CPU 50, a normal symbol memory 51, a special symbol memory 52, and an effect memory 53.

  The display CPU 50 controls display of images displayed from the liquid crystal panel 18. The special symbol memory 52 stores display data for displaying an image from the liquid crystal panel 18. The display CPU 50 reads the display data in the special symbol memory 52 and causes the liquid crystal panel 18 to perform a special symbol variation display and a stop display. The CPU 50 for display identifies which special symbol is displayed from the liquid crystal panel 18 by monitoring the head address assigned to each special symbol displayed on the liquid crystal panel 18, thereby changing the special symbol display. To do. The result of the lottery in the special symbol determination unit 36 a is input from the CPU 33 to the display CPU 50. The display CPU 50 stops and displays the normal symbols that are variably displayed so that the combination of the special symbols determined by the special symbol determination unit 36a is displayed.

  The normal symbol memory 51 stores display data for displaying a normal symbol from the normal symbol display 19. The display CPU 50 reads the display data in the normal symbol memory 51 and causes the normal symbol display device 19 to perform normal symbol variation display and stop display. Then, the display control of the normal symbol is performed in the same manner as the special symbol, and the normal symbol variably displayed is stopped and displayed so that the normal symbol determined by the normal symbol determining unit 36b is displayed.

  The effect memory 53 stores display data for performing an effect on the liquid crystal panel 18 for notifying the player of the time required for the normal symbol to stop. In the effect memory 53, for example, the time until the normal symbol stops is less than 5 seconds, 5 seconds to less than 10 seconds, 10 seconds to less than 15 seconds, 15 seconds to less than 20 seconds, 20 seconds to less than 25 seconds, 25 seconds The display data of the six types of effects divided into the above six ranges and corresponding to the respective ranges are stored. Then, the display CPU 50 determines that the lottery table used in the open lottery is the first lottery when the normal mode changes from the hit mode to the short time mode while the normal symbol is variably displayed, that is, while the normal symbol is variably displayed. When the table 37a is switched to the second lottery table 37b, it is identified which of the above-described six types of ranges the change time from the transition to the time reduction mode to the normal symbol stop display. Then, the type of effect to be displayed from the liquid crystal panel 18 is determined according to the identified result, and graphic data corresponding to the determined effect is read out. As a result, the liquid crystal panel 18 notifies the player of the variation time from the transition to the time reduction mode to the normal symbol being stopped and displayed by one of the six types of effects.

  The lamp control device 45 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 46 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 47 is activated when any of the start port sensor 40, the big prize port sensor 41, and the passage port sensor 42 detects a pachinko ball. The payout control device 47 includes a memory, and the memory stores a payout table in which the number of pachinko balls to be paid out for a single pachinko ball win and the type of the winning mouth are associated with each other. The payout control device 47 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. Note that when a pachinko ball is detected at the passage port 14, the player may pay out the pachinko ball.

  The movable member control device 48 is connected to a solenoid (not shown) that drives the movable member 13a. The movable member control device 48 is activated when the open lottery is won. The result of the open lottery is input from the CPU 33. When the movable member control device 48 recognizes that the open lottery is won, the movable member control device 48 rotates the movable member 13a from the closed position to the open position. When the open lottery is performed using the first lottery table 37a, the movable member control device 48 holds the movable member 13a at the open position for 0.5 seconds, and the open lottery is performed using the second lottery table 37b. In such a case, the movable member 13a is held at the open position for 2 seconds. The movable member control device 48 also drives a solenoid or the like that drives the attacker 15.

  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. First, the flow of the entire game of the pachinko machine 10 will be described with reference to FIG. In the pachinko machine 10, a game in the normal mode is first performed. When the player operates the firing handle 10a, a pachinko ball launched into any of the start port 13, the passage 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 special symbol determination unit 36a is operated, and the combination of special symbols to be stopped and displayed on the liquid crystal panel 18 is determined by lottery. After that, if the winning symbol is selected in the winning lottery when the signal indicating the type of the special symbol to be stopped and displayed on the display CPU 50 is transmitted from the CPU 33, the winning symbol is displayed by the special symbol. Then, the CPU 33 reads the hit mode execution program from the memory 34 and shifts from the normal mode to the hit 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. When the end condition in the winning mode (the big winning opening 17 is opened 15 times), the CPU 33 reads the execution program in the time-saving mode from the memory 34 and shifts from the winning mode to the time-saving mode. In the time reduction mode, the CPU 33 writes the number of times in the memory 34 and updates it every time the symbol is variably displayed. In the time reduction mode, when the symbol variation display is performed 100 times, the time reduction mode is terminated and the mode is changed to the normal mode.

  Next, the flow of the game when a pachinko ball is detected at the passage port 14 will be described using the flowchart of FIG. When a pachinko ball is detected at the passage port 14, the CPU 33 determines whether or not the mode is shifted to the time reduction mode. When the mode is shifted to the time reduction mode, a table selection signal indicating the second lottery table 37 b is input to the open lottery unit 37. In response to this, the open lottery unit 37 performs an open lottery using the second lottery table 37b. Thereby, in the short time mode, the winning probability of the open lottery is higher (high probability) than in the normal mode and the winning mode. In addition, the CPU 33 operates the normal symbol determination unit 36b to determine the normal symbol to be stopped and displayed. The CPU 33 then activates the timer 38 and transmits a normal symbol variation start signal to the display CPU 50. In response to this, the display CPU 50 reads normal symbol display data from the normal symbol memory 52 and starts normal symbol variation display. When the count value of the timer 38 reaches 5 seconds, the CPU 33 transmits a normal symbol stop signal to the display CPU 50 to stop the operation of the timer 38 and reset the count value of the timer 38. In response to the stop signal, the CPU 33 stops and displays the normal symbol. When the open lottery is won, the odd symbols are stopped and displayed, and the movable member 13a is moved to the open position. When the movable member 13a is held at the open position for 2 seconds, it is moved to the closed position.

  In addition, when a pachinko ball is detected at the passage port 14 when the mode is not shifted to the time-saving mode, that is, when the mode is shifted to the normal mode or the hit mode, the CPU 33 stores the first lottery table 37a in the open lottery unit 37. The table selection signal shown is input. In response to this, the open lottery unit 37 performs an open lottery using the first lottery table 37a. Thereby, in the normal mode and the winning mode, the winning probability of the open lottery is lower (low probability) than in the short-time mode. Then, the normal symbol is stopped and displayed after a change display of 30 seconds by the same processing as in the time reduction mode.

  Here, when the shift from the hit mode to the short-time mode during the normal symbol variation display, that is, when the lottery table used in the open lottery is switched from the first lottery table 37a to the second lottery table 37b, the CPU 33 sets the timer 38. Referring to FIG. 4, the fluctuation time from the transition to the time-saving mode until the normal symbol is stopped and displayed is identified. The identified variation time is transmitted to the display CPU 50. In response to this, the CPU 50 for display identifies which of the six types of variation times transmitted from the CPU 33 belongs to, and displays display data for executing an effect corresponding to the identified range from the effect memory 53. read out. Then, the display CPU 50 performs an effect on the liquid crystal panel 18 based on the read display data, and informs the player of the variation time from the transition to the time reduction mode until the normal symbol is stopped and displayed.

  When the open lottery is won, the odd symbols are stopped and displayed, and the movable member 13a is moved to the open position. When the movable member 13a is held at the open position for 0.5 seconds, it is moved to the closed position.

  FIG. 5 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 recording medium 60 has means as shown in the flowcharts of FIGS. A program to be realized by the computer 61 including the CPU 33 and the memory 34 is stored. In this case, for example, when a predetermined game condition is satisfied, table selection means for switching the lottery table used in the lottery for determining whether or not to move the movable member that widens the area where the game ball wins a prize opening. Display control means for shortening the variation time of the normal symbol that informs the result of the lottery as the winning probability in the lottery table used in the lottery increases, and the winning probability during the variation display of the normal symbol A program for causing the computer 61 to function as a fluctuating time informing means for informing the time until the normal symbol being fluctuated and displayed is stopped when the lottery table having a low win probability is switched to the lottery table having a high winning probability. 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 predetermined game condition for switching the lottery table used in the open lottery is that the mode is changed from the hit mode to the time-saving mode and the time-saving mode is changed to the normal mode. Number of times performed, whether or not the lottery to switch the lottery table was won, the number of pachinko balls launched reached a predetermined number, the time counted by the timer reached a certain time, the pachinko that won the prize opening Achieved by playing the game, such as the number of balls reaching a certain number, the number of pachinko balls that did not win the prize opening (the number of pachinko balls entering the out port 16) reached a certain number, etc. If it is a condition, the content of the predetermined game condition may be set as appropriate.

  In the above embodiment, two types of winning probabilities are set for the open lottery. However, if the winning probability of the open lottery increases, the normal symbol variation time becomes shorter. It's okay.

  In the above embodiment, a pachinko machine has been described as an example of a ball game machine. However, a lottery is performed to determine whether or not to move a movable member that widens an area where a game ball wins a prize opening, and the stop is displayed. The present invention can be applied to other ball game machines as long as the result of the lottery is notified according to the type of normal symbol.

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 the whole game. It is a flowchart which shows the flow of the game when a pachinko ball is detected at the passage. It is explanatory drawing in the case of installing the recording medium in which the program was stored in the pachinko machine.
