Description

  The present invention relates to a ball game machine such as a pachinko game machine, and more particularly, to an effect control technique in a ball game machine.

  Various types of pachinko machines are popular as bullet ball machines. Among conventional pachinko gaming machines, when a game ball enters a start port formed on a game board, a lottery value is randomly acquired as a result. The acquired lottery values are temporarily stored, for example, up to four as reserved balls. The reserved balls are sequentially read one by one. The read lottery value is determined whether or not the winning symbol is determined, and a symbol called a special symbol is variably displayed.

When the special symbol is stopped and displayed in the winning mode, the gaming state shifts to a special game as a so-called “big hit”. A special game is composed of a plurality of unit games. The big prize opening formed on the game board is opened at the start of the unit game. The unit game ends when a predetermined period, for example, 30 seconds elapses from the start of the unit game, or when nine or more game balls are won in the big prize opening during the unit game. At this time, the grand prize opening is also closed. During a unit game, if the game ball passes through a specific area called a V zone provided in the special winning opening, the unit game is continued to the next unit game. At this time, the grand prize opening is opened again. The unit game can be continued up to a predetermined number of times, for example, 15 times. When the game balls fall into the big prize opening, more game balls than usual are paid out as prize balls.
A general player plays a game for the purpose of opening a special winning opening in order to obtain a lot of prize balls, that is, shifting the gaming state to a special game (see, for example, Patent Document 1).

  As described above, there is a “deviation” between the execution timing of the success / failure determination and the notification timing, which is a special symbol variation display period. When the variation display of the special symbol is started, the player expects the special symbol to stop in a winning manner. Therefore, in many cases, an effect that further enhances the player's expectation for the jackpot is performed by variably displaying an effect-designated symbol called a decorative symbol or an effect symbol during the special symbol variation display period.

As an example, there is a ball game machine in which effect symbols are variably displayed in three variable rows simulating a slot machine game. The variation display of the effect symbol is stopped in accordance with the stop timing of the special symbol, in other words, the notification timing of the success / failure. In the case of a big hit, three same effect symbols are stopped and displayed side by side. The player can recognize the success or failure not only by the stop pattern of the special symbol but also by the stop pattern of the effect symbol. In general, since the size of the effect symbol is often set to be much larger than the size of the special symbol, the player will pay attention to whether the same effect symbol is arranged three times than the stop state of the special symbol. Become.

In addition, there are many pachinko machines that display a command (mission) such as “Get a reach of 2 within 10 revolutions” during the dynamic display of the effect symbols. In this case, when the “2 reach” is established, the big hit is decided before the three “2” s are arranged. Even if three production symbols are not prepared, if the reach is “2”, the jackpot is confirmed, so that a psychological effect as if the possibility of the jackpot is increased can be induced. “Mission production”, in which profits are granted by accomplishing missions, is an effective production technique for raising the player's expectation, and has been adopted in many pachinko machines.
The present inventor has conceived that a new game entertainment can be provided by changing the length of such a mission effect according to the progress of the game.

  The present invention is an invention completed based on the above recognition of the present inventor, and its main object is to provide a technique for further deepening the effect of producing a mission effect.

One embodiment of the present invention relates to a ball game machine.
This ball game machine is a lottery with the game board in which the game area is formed, the start prize opening provided at a predetermined position of the game area and the game ball can enter, and the entry into the start prize opening. A lottery value acquisition means for acquiring a value, a success / failure lottery means for executing a success / failure lottery for determining the success / failure based on the lottery value, a special figure display control means for variably displaying a special symbol indicating the result of the success / failure lottery, A game that is provided at a predetermined position in the game area and can be opened in a state where a game ball can enter, and when the special symbol is stopped in a state showing a win, the game is performed by opening the grand prize opening. Special game control means for executing a special game advantageous to the user, and an effect having a period that can include a variable display of a plurality of special symbols as an effect period, and for the result of multiple lottery results shown during the effect period To raise the player's expectations Special effect data holding means for holding special effect data indicating the contents of the special effect, special effect executing means for executing the special effect according to the special effect data when a predetermined game condition is established, and a start winning opening for a predetermined period And an entrance amount measuring means for measuring the entrance amount to the.
The special performance execution means was measured in accordance with a performance period determination rule that associates the length of the special performance performance period with the amount of incoming balls in order to change the length of the special performance stage according to the amount of incoming balls. The length of the production period corresponding to the amount of incoming balls is specified.

  The “special effect” referred to here may be a so-called mission effect, but it may be an effect that is executed over a long period of time that may include a plurality of special symbol fluctuation times. “Amount of entered balls” may be the number of balls entered at the start winning opening during a predetermined period, or may be the probability that a game ball launched during the predetermined period will enter the start winning opening. Alternatively, it may be the number of times that a new symbol change has been started during a predetermined period triggered by entering the starting prize opening. In any case, the “entry amount” may be an index value that directly or indirectly indicates the ease of entering the start winning opening.

  When the amount of entered balls is large, it can be said that the game is in a state where the starting winning opening is successively entered, so that the tempo of the game is in a good state. When the amount of incoming balls is large, the special effect may be lengthened or conversely shortened. When the game tempo is poor, some players do not like to perform the same special effects for a long time. Rather, some players prefer to enjoy long special effects. By changing the length of the special effect according to the amount of balls entered, the length of the special effect can be adjusted during the game in accordance with the game tempo. The relationship between the game tempo and the length of the special performance may be arbitrarily set according to the target player.

  The special effect executing means may adjust the length of the effect period of the special effect corresponding to the measured amount of entering balls during execution of the special effect.

  According to such an aspect, the length of the special effect can be dynamically changed even during the special effect. For example, the player can control the length of the special effect at his / her own will by not intentionally entering the starting prize opening during the special effect.

You may further provide the holding means which hold | maintains a lottery value by making a predetermined number into an upper limit.
If the number of lottery values already held in the holding means has not reached the predetermined number, the lottery value acquiring means acquires the lottery value and records it in the holding means. The winning and winning lottery is performed, and the pitch measurement means enters the game balls for which the lottery value has been acquired using the pitch as a trigger among the game balls that have actually entered the start prize opening during the predetermined period. The amount may be measured.

  According to such an aspect, so-called invalid winnings can be excluded from the calculation of the amount of winning. Since the length of the special effect can be controlled according to the frequency of occurrence of the effective winnings, it becomes easier to link the game tempo felt by the player and the length of the special effect.

  The special effect execution means refers to the effect period determination rule associating the number of fluctuations of the special symbol included in the effect period of the special effect and the amount of incoming balls, and measures the number of changes of the special symbol included in the effect period of the special effect. By selecting according to the amount of entered balls, the length of the special effect production period may be changed according to the measured amount of entered balls.

  By adjusting the number of fluctuations included in the special performance according to the amount of entering balls, it becomes easier for the player to see the change in the length of the performance period.

Another aspect of the present invention is also a ball game machine.
This ball game machine is a lottery with the game board in which the game area is formed, the start prize opening provided at a predetermined position of the game area and the game ball can enter, and the entry into the start prize opening. A lottery value acquisition means for acquiring a value, a success / failure lottery means for executing a success / failure lottery for determining the success / failure based on the lottery value, a special figure display control means for variably displaying a special symbol indicating the result of the success / failure lottery, A game that is provided at a predetermined position in the game area and can be opened in a state where a game ball can enter, and when the special symbol is stopped in a state showing a win, the game is performed by opening the grand prize opening. Special game control means for executing a special game advantageous to the user, and an effect having a period that can include a variable display of a plurality of special symbols as an effect period, and for the result of multiple lottery results shown during the effect period To raise the player's expectations Special effect data holding means for holding special effect data indicating the contents of the special effect, special effect execution means for executing the special effect according to the special effect data when a predetermined game condition is established, and a special symbol in the predetermined period Fluctuation rate calculating means for calculating the ratio of the period during which the change is displayed as a fluctuation rate.
The special effect execution means calculates the rate of change calculated according to the effect period determination rule that associates the length of the effect period of the special effect with the rate of change in order to change the length of the effect period of the special effect according to the rate of change. The length of the production period corresponding to is specified.

  The “variation rate” may be a ratio of the variation time of the special symbol in a predetermined period. The “variation rate” may be an index value that directly or indirectly indicates the short period of time during which the special symbol does not vary.

  When the rate of change is high, it can be said that the expectation for the jackpot is difficult to be interrupted, so it can be said that the game progress is in a steady state. Even if the amount of incoming balls is small, the player can easily make an impression that the game progresses smoothly if the special symbol constantly fluctuates. When the rate of change is high, the special effect may be lengthened or conversely shortened. When the game progress is not smooth, there are some players who do not like the same special effects being executed for a long time, and there are other players who want to enjoy long special effects slowly. By changing the length of the special effect according to the rate of change, the length of the special effect can be adjusted during the game according to the progress of the game. The relationship between the progress pace of the game and the length of the special effect may be arbitrarily set according to the target player.

  It should be noted that any combination of the above-described constituent elements and a conversion of the expression of the present invention between a method, an apparatus, a system, a recording medium, a computer program, etc. are also effective as an aspect of the present invention.

  According to the present invention, it is possible to further deepen the entertainment interest by the mission effect in the ball game machine.

FIG. 1 shows a basic structure on the front side of a pachinko gaming machine.
Hereinafter, a so-called first type pachinko gaming machine, which is conventionally known as a bullet ball gaming machine, will be described as an example. The pachinko gaming machine 10 is mainly composed of a gaming machine frame and a gaming board. The gaming machine frame of the pachinko gaming machine 10 includes an outer frame 11, a front frame 12, a transparent plate 13, a door 14, an upper ball dish 15, a lower ball dish 16, and a launch handle 17. The outer frame 11 has an opening and is a frame for fixing the pachinko gaming machine 10 to a position where it should be installed. The front frame 12 is a frame body that aligns with the opening portion of the outer frame 11, and is attached to the outer frame 11 so as to be opened and closed by a hinge mechanism (not shown). The front frame 12 includes a mechanism for launching a game ball, a mechanism for detachably storing a game board, a mechanism for guiding or collecting the game ball, and the like.

  The transparent plate 13 is made of glass or the like and is supported by the door 14. The door 14 is attached to the front frame 12 so as to be openable and closable by a hinge mechanism (not shown). The upper ball tray 15 has a mechanism for storing game balls, sending out the game balls to the launch rail, and extracting the game balls to the lower ball tray 16. The lower ball tray 16 has a mechanism for storing and extracting game balls. A speaker 18 is provided between the upper ball tray 15 and the lower ball tray 16, and a sound effect corresponding to the gaming state is output. The operation button 82 is operated in order for the player to input a predetermined instruction to the gaming machine. The operation button 82 is provided on the outer wall surface near the upper ball tray 15.

  The game board 50 has an out port 58, a special symbol display device 61, an effect display device 60, and a start winning port (hereinafter referred to as “start port”) 62 on a game area 52 defined by the outer rail 54 and the inner rail 56. , A center ornament 64, a grand prize opening 66, an operation opening 68, and a general prize opening 72. Further, in the game area 52, a plurality of mechanisms such as a game nail and a windmill (not shown) are installed. The start port 62 includes a start winning detection device 74 for detecting the entrance of a game ball and a normal electric accessory solenoid 76 for expanding the expanding mechanism of the start port 62. When the start port 62 is expanded, the game ball easily enters the start port 62. The start winning detection device 74 is a sensor that detects the entry of a game ball into the start port 62, and generates start win information indicating the winning at the time of entering. The general winning opening 72 includes a general winning detecting device 73 for detecting the entering of a game ball. The general winning detection device 73 is a sensor that detects the entry of a game ball into the general winning opening 72, and generates general winning information indicating the winning at the time of winning. The special winning opening 66 includes a winning detection device 78 for detecting the entry of a game ball and a special winning opening solenoid 80 for expanding the special winning opening 66. The winning detection device 78 is a sensor that detects the entry of a game ball into the big winning opening 66, and generates big winning opening winning information indicating the winning at the time of winning.

  The big winning opening 66 is a horizontal rectangular winning opening that is opened when the special symbol 192 is stopped in a mode indicating “big hit”. The big winning opening 66 is provided above the out opening 58 and the like. The winning detection device 78 of the big winning opening 66 includes a sensor that detects the passage of a game ball.

  When the player turns the launch handle 17 by hand, the game balls stored in the upper ball tray 15 are guided one by one to the inner rail 56 and the outer rail 54 with a strength corresponding to the turning angle, thereby playing the game area. To 52. When the player fixes the rotation position of the firing handle 17 by hand, the game ball is repeatedly fired at regular time intervals. The game ball launched to the upper part of the game area 52 falls in a direction according to the way of hitting while hitting a plurality of game nails and windmills. When a game ball is dropped into each of the general winning port 72, the start port 62, and the big winning port 66, the winning ball corresponding to the type of the winning port is paid out to the upper ball plate 15 or the lower ball plate 16. A game ball dropped into each winning hole such as the general winning hole 72 is processed as a safe ball, and a game ball dropped into the out hole 58 is processed as an out ball. Each winning opening includes a gate type through which a game ball passes. In this application, “incoming”, “entering”, and “winning” include “passing”.

  The special symbol display device 61 provided on the left side of the game area 52 and the effect display device 60 provided substantially in the center of the game area 52 have a variation of the special symbol 192 on each screen and an effect linked to the special symbol 192. The variation of the effect image including the symbol 190 is displayed (hereinafter, such display is referred to as “symbol variation” or “variation display”). A lottery (hereinafter referred to as “winning lottery”) is executed in response to the entry of the game ball into the start port 62. After the winning / losing lottery, the variable symbol 192 starts to be displayed. The special symbol 192 is a symbol corresponding to the result of the success / failure lottery, and shows the result of the success / failure lottery in a mode when the variable display is stopped. The special symbol display device 61 is a display means composed of, for example, a 7-segment LED. The special symbol display device 61 circulates numbers in the range of 0 to 9 as a variation display of the special symbol 192. When the special symbol 192 is stopped in a manner showing a win, a “big win” is generated, and the big winning opening 66 is opened.

The result of the winning / failing lottery is either a big hit or a failure, but the big hit can be further divided into two types of “normal win” and “probable win”. When the probability change wins, the subsequent winning lottery is executed with a higher win probability than usual. A gaming state that is advantageous to a player in which the winning probability of winning / failing lottery is set higher than usual is referred to as “probability variation game (probability variation)”. The probability variation game continues until a big hit occurs again. In other words, it will continue until a normal win occurs.
The special symbol 192 is stopped and displayed as a stop symbol, which is 0 for normal hit, 1 for likely change, and 2 to 9 for miss.

  The effect display device 60 is a liquid crystal display that variably displays the effect symbol 190 in a manner interlocked with the variable symbol display of the special symbol 192. The production symbol 190 is a symbol for visually producing the result display of the success / failure lottery. On the screen of the effect display device 60, an effect image including a variation display mode of the effect symbol 190 is reproduced and displayed as a moving image. The variation display of the effect symbol 190 is linked with the variation display of the special symbol 192. That is, the variation display of the effect symbol 190 is started when the variation of the special symbol 192 is started, and the variation display of the effect symbol 190 is also stopped when the variation of the special symbol 192 is stopped. Further, according to the stop symbol of the special symbol 192, in other words, the stop symbol of the effect symbol 190 is also determined according to the result of the lottery. The screen of the effect display device 60 is provided with three symbol areas, that is, a left variation column, a center variation column, and a right variation column. In each variation column, the effect symbol 190 is variably displayed in the vertical direction from top to bottom. This is an effect that mimics the reel of a slot machine.

  Since the special symbol 192 does not necessarily have a role of production, in the present embodiment, the special symbol 192 is displayed in an inconspicuous size on the special symbol display device 61 at the lower left of the production display device 60. When adopting a technique in which the effect symbol 190 is not displayed and the effect symbol 190 is not displayed, the special symbol 192 may be displayed on a liquid crystal display such as the effect display device 60.

  The variation display of the special symbol 192 and the effect symbol 190 is stopped after the lapse of the variation time determined prior to the display. When the special symbol 192 and the effect symbol 190 at the time of the stop are symbols indicating a big hit, the game shifts to a special game that is more advantageous to the player than the normal game, and the opening / closing operation of the big prize opening 66 is started. At this time, the effect symbol 190 simulating the game of the slot machine takes a display mode in which the three symbols are matched. In the special game, the grand prize winning slot 66 is temporarily closed after being opened for about 30 seconds or after nine or more game balls are dropped. If at least one game ball is dropped while the big prize opening 66 is open, the big prize opening 66 is opened again. In this way, the opening / closing of the big prize opening 66 is repeated up to a predetermined number of times, for example, 15 times, on condition that at least one game ball is dropped while the big prize opening 66 is opened once.

  The operation port 68 is provided at the left side position of the game board 50. The operation port 68 includes a passage detection device 69. The passage detection device 69 is a sensor that detects the passage of the game ball to the operation port 68, and generates passage information indicating the passage at the time of passage. The passing of the game ball to the operation port 68 triggers a lottery (hereinafter referred to as “normal symbol lottery”) for expanding the start port 62.

  When the game ball passes through the operation port 68, the normal symbol lottery is executed, and the normal symbol is variably displayed on the normal symbol display device 59 for a predetermined time. The normal symbol display device 59 is provided on the lower right side of the effect display device 60. The normal symbol display device 59 includes two lamps. The operation in which the respective lamps alternately flash is an operation corresponding to “ordinary symbol variation display”. When the normal symbol variation display is stopped after a lapse of a predetermined time, the start port 62 is normally expanded for a predetermined time with a probability of about 50% to 80%, and the game ball easily enters the start port 62. At this time, one of the two lamps of the normal symbol display device 59 is lit up.

  A center ornament 64 is provided around the effect display device 60. The center decoration 64 has functions such as a flow path of the game ball, protection of the special symbol display device 61 and the effect display device 60, and decoration. The effect display device 60 includes a plurality of movable accessories 140 that operate in accordance with the gaming state. A lottery hold lamp 20 is provided at the lower left of the effect display device 60, and an operation hold lamp 22 is provided below the normal symbol display device 59 at the lower right of the game area 52, which is a symmetrical position. Yes. The lottery hold lamp 20 is composed of four lamps, and displays the number of lottery holds depending on the number of lights. The number of lottery holds is the number of lottery results won to the start port 62 during symbol variation or special game, and indicates the number of winning balls for which symbol variation has not yet been executed. In other words, the lottery value can be stored up to four. The operation hold lamp 22 is also composed of four lamps, and displays the number of hold of normal symbol fluctuations depending on the number of lights. The number of normal symbol fluctuations held is the number of game balls that have passed through the operation port 68 during the fluctuation of the normal symbol, and indicates the number of normal symbol lotteries for which the fluctuation of the normal symbol has not yet been executed. In this way, it is possible to store a lottery value of normal symbols with an upper limit of four. The game effect lamp 90 is provided in the game area 52 and plays a role of effect by blinking.

  In the case of normal winning, after the special game is ended, the “variable time shortening game (short time)” is started. In the variation time shortening game, the variation time of the special symbol 192 and the effect symbol 190 is shortened from the normal time. In addition, the probability of winning a normal symbol lottery increases. The winning probability of the normal symbol lottery in this embodiment is usually 50%, but 80% when the time is short. Time saving ends after a predetermined number of special symbol changes. The time saving in this embodiment continues for 100 symbol variations.

Hereinafter, the probability variation game (probability variation) and the variation time shortening game (time reduction) are collectively referred to as “specific game”. The specific games in this embodiment are summarized as follows.
1. Probability: After a special game due to the occurrence of a probability change, the game shifts to a probability change and continues until the next normal success occurs.
2. Shorter time: After a special game due to normal occurrence, the time shifts to shorter time and continues until the number of symbol fluctuations after the start of the shorter time reaches 100 times. Even before the number of symbol fluctuations after the start of time reduction reaches 100, the time reduction ends when a big hit occurs.

FIG. 2 shows a basic structure on the back side of the pachinko gaming machine.
The power switch 40 is a switch for turning on / off the pachinko gaming machine 10. The main board 102 controls the overall operation of the pachinko gaming machine 10 and processes all game operations such as a lottery when a winning is made to the start port 62. The sub board 104 includes the liquid crystal unit 42 and controls display contents on the effect display device 60, operations of the plurality of movable objects 140, and lighting of the game effect lamp 90, and in particular, display contents according to the lottery result by the main board 102. And the lighting of the movable accessory 140 and the game effect lamp 90 is activated along with the progress of the production. The main board 102 and the sub board 104 constitute a game control device 100. The set base 39 includes a prize ball tank 44, a flow path for prize balls, a payout unit 43 for delivering prize balls. The payout unit 43 pays out the game balls supplied from the winning ball tank 44 to the upper ball tray 15 in accordance with winning in each winning opening. The payout control board 45 controls the payout operation by the payout unit 43. The launching device 46 launches the stored balls in the upper ball tray 15 to the game area 52 one by one. The launch control board 47 controls the launch operation of the launch device 46. The power supply unit 48 supplies power to each part of the pachinko gaming machine 10.

FIG. 3 shows functional blocks of the pachinko gaming machine 10 in this embodiment.
In the pachinko gaming machine 10, the game control device 100 includes a start port 62, a big winning port 66, a general winning port 72, an operating port 68, a special symbol display device 61, an effect display device 60, a normal symbol display device 59, and operation buttons 82. The speaker 18, the game effect lamp 90, and the movable accessory 140 are electrically connected to each other, and can transmit and receive various control signals. The game control apparatus 100 controls not only the basic operation of the game but also the staging operations such as the symbol variation display, the movable accessory 140, and the electric decoration. The game control device 100 is configured in such a manner that functions are shared between a main board 102 that controls the overall operation of the pachinko gaming machine 10 including basic operations of the game, and a sub board 104 that controls design effects and the like. The game control device 100 is configured by hardware including elements such as a ROM and a RAM for storing data and programs, and a CPU used for arithmetic processing.

The main board 102 includes a ball entering determination unit 110, a lottery value acquisition unit 111, a winning / failing lottery unit 112, a symbol determination unit 114, a hold control unit 116, a main display control unit 118, a special game control unit 120, a specific game execution unit 122, Opening / closing control means 124 is provided. The sub-board 104 includes a number-of-balls measuring unit 126, a variation rate calculating unit 128, an effect data storage unit 130, an effect determining unit 132, an effect display control unit 134, and an accessory control unit 136.
Each functional block included in the main board 102 may be configured such that any one of the functional blocks is mounted on the sub board 104 instead of the main board 102. Similarly, each functional block included in the sub-board 104 may be configured such that any one of them is mounted on the main board 102 instead of the sub-board 104.

  The entrance determination means 110 determines whether or not a game ball has entered each winning opening. When receiving the start winning information, the winning determination means 110 determines that the game ball has won the start opening 62, and when receiving the big winning opening winning information, determines that the game ball has won the big winning opening 66, and the general winning is obtained. When the information is received, it is determined that the game ball has won the general winning opening 72. When receiving the passage information, the ball entering determination unit 110 determines that the game ball has passed through the operation port 68.

  The lottery value acquisition unit 111 acquires a random value as a “winning lottery value” in order to determine whether or not to shift from the normal game to the special game when the game ball enters the start port 62. One winning / failing lottery value is acquired from the range of 0 to 65535. The “random number” in the present application may not be a mathematically generated random number, but may be a pseudo-random number generated by a hardware random number, a software random number, or the like. The success / failure lottery means 112 holds a plurality of success / failure tables to be referred to in the success / failure determination. In the plurality of success / failure tables, the determination result of winning or losing is associated with the winning / losing lottery value, and the success / failure probability is determined according to the associated winning range setting.

  The winning / failing lottery means 112 refers to a success / failure determination table (hereinafter referred to as “non-probability variation appropriateness / prohibition table”) for determination of success / failure with a low probability except when the probability variation game is being executed. Reference is made to a success / failure table (hereinafter, referred to as a “probability change success / failure table”) for determination of success / failure by probability. In the non-probability change acceptance / rejection table, a success / failure lottery value in the range of 0 to 255 is determined to be winning. In the probability variation success / failure table, the success / failure lottery value in the range of 0 to 2500 is determined to be winning. The success / failure lottery means 112 executes the success / failure lottery by referring to any of the success / failure tables and determining whether or not the success / failure lottery value is a win. The determination result by the success / failure lottery means 112 is indicated by special symbol variation in the special symbol display device 61. Further, the determination result by the success / failure lottery means 112 is also indicated by the production symbol variation.

  The symbol determining means 114 determines the stop symbol and the variation pattern of the special symbol 192 to be displayed on the special symbol display device 61 according to the result of the lottery determination. Further, the symbol determining means 114 determines the stop symbol of the normal symbol to be displayed on the normal symbol display device 59 according to the result of the normal symbol lottery. The stop symbol is a symbol indicating whether or not to be displayed at the end of symbol variation. The symbol determination unit 114 holds a pattern determination table for determining a variation pattern.

  The symbol determination means 114 acquires a “pattern determination lottery value” for determining the variation pattern at the start of variation of the special symbol 192. The pattern determination lottery value is a random number generated in the range of “0 to 255”. The pattern determination table is a determination table that defines the correspondence between the pattern determination lottery value and the variation pattern of the special symbol. The symbol determination means 114 determines a variation pattern from the pattern determination table and the pattern determination lottery value. Thus, the variation time of the special symbol 192 is determined.

  The symbol determination means 114 holds a plurality of types of variation patterns having various variation times. Each variation pattern has a variation time for each pattern as an end condition of the symbol variation, and the special symbol variation is stopped when the variation time elapses.

Further, the symbol determining means 114 determines the stop symbol pattern of the special symbol according to the “symbol lottery value” generated in the range of 0 to 255. The symbol determination means 114 generates a symbol lottery value at the time of execution of the success / failure lottery. When the winning / losing lottery value is a win, it is determined based on the symbol lottery value whether it is a normal hit or a probable change. Note that if the winning / failing lottery value is off, any one of a plurality of types of off symbols is determined as a stop symbol.
The symbol determination means 114 sends the variation pattern ID and the stop symbol to the main display control means 118 and the effect determination means 132 as a result of the success / failure lottery.

  When the game ball passes through the operation port 68, the symbol determination means 114 acquires a lottery value for determining a normal symbol, and determines a stop symbol of the normal symbol according to the lottery value. When the stop symbol of the normal symbol is a specific symbol, the opening / closing control means 124 widens the start port 62 for a predetermined time.

  The hold control unit 116 holds the winning / not-lotting value acquired by the lottery value acquiring unit 111 as a holding ball. The success / failure lottery value is accumulated until the number of holds reaches a predetermined upper limit. The upper limit of the number of holds is 4. The hold control means 116 holds the upper limit of four as a result of the normal symbol lottery.

  Even if a ball is entered into the start port 62 when the number of held balls has reached the upper limit, it becomes an invalid prize, and a new winning / failing lottery value is not acquired. That is, the lottery value acquisition unit 111 does not acquire a new winning / failing lottery value even if the start winning information is received when the number of held balls held in the holding control unit 116 reaches the upper limit of four.

  The main display control means 118 causes the special symbol display device 61 to variably display the special symbol 192. The main display control means 118 transmits a change start command and a change stop command to the effect display control means 134 at the timing of starting and stopping the change display of the special symbol 192, thereby allowing the special display by the main display control means 118. The variation display of the effect symbol 190 by the symbol 192 and the effect display control means 134 is synchronized, and the interlock is maintained. The main display control means 118 displays the normal symbol variation on the normal symbol display device 59.

  The special game control means 120 controls the execution of the special game when the winning lottery is a win. The special game is a game in which the opening / closing operation of the special winning opening 66 is continuously continued a plurality of times, and is constituted by one or a plurality of unit games with one opening / closing as a unit. The unit game is repeated up to 15 times, for example, and the grand prize opening 66 is opened for about 30 seconds in one unit game. If the number of continuations of the unit game has not reached the upper limit number, the special game control means 120 starts the next unit game after the end of the current unit game. When the upper limit number of unit games is exhausted, the special game is terminated.

  The specific game execution means 122 executes control for shifting the game state from the normal state to the specific game state, and control for returning the specific game state to the normal state. The specific game according to the present embodiment includes a probability change in which the winning probability of winning / failing lottery is switched from a normal probability state to a high probability state and a short time in which the symbol variation time is switched from a normal time to a short time.

The specific game execution means 122 executes the probability variation game by setting the normal game after the special game to a high probability state when the probability change has occurred. At this time, the specific game executing means 122 sets a probability change success / failure table as a success / failure table to be referenced by the success / failure lottery means 112 for the success / failure lottery. In principle, the high probability state is continued until the next jackpot is generated, and during that time, the winning probability by the success / failure lottery means 112 is maintained at a high value. If the normal win occurs in the high probability state, the normal game after the end of the special game is in the low probability state. In other words, the specific game execution means 122 sets a non-probability change success / failure table as a success / failure table to be referenced by the success / failure lottery means 112 for the success / failure lottery.
In addition, when a normal win occurs, the specific game executing means 122 executes the game with a reduced variation time by setting the normal game to the time-saving state after the special game. The time reduction is continued until the number of symbol variations reaches 100.

  The opening / closing control means 124 controls the opening / closing of the ordinary electric accessory at the start opening 62 and the special winning opening 66. When the normal symbol is stopped at a specific symbol, the opening / closing control unit 124 sends an opening instruction to the ordinary electric accessory solenoid 76 to open the start port 62. Further, the opening / closing control means 124 sends an opening instruction to the special winning opening solenoid 80 during the special game, and opens the special winning opening 66.

The effect data storage means 130 of the sub-board 104 holds an effect pattern indicating the moving image reproduction process of the effect image including the change display of the effect symbol 190. The production pattern includes the fluctuation pattern of the production symbol 190 when displaying a normal out symbol, the fluctuation pattern when displaying a symbol out of a reach after reaching a big win if one more symbols are aligned, and the reach state. The variation pattern when displaying the jackpot symbol is included. In particular, the variation pattern in the reach state includes a variation pattern having various variation times. For each effect pattern, a change time is defined as an end condition of the symbol change, and the change display of the effect symbol 190 is stopped when the change time elapses. The effect determining means 132 selects an effect pattern having the same variation time as that of the special symbol in accordance with the variation pattern of the special symbol.
In the following, the variation time of the special symbol 192 and its variation process are referred to as “variation pattern of the special symbol 192” or simply “variation pattern”, and the variation time of the production symbol 190 and its variation process are referred to as “the production symbol 190 The data indicating the moving image reproduction process of the effect image including the change pattern ”and the change display of the effect symbol 190 is referred to as“ effect pattern ”.

  The effect determining means 132 determines the combination of stop symbols of the effect symbols 190 and their arrangement and effect pattern according to the result of the lottery determination, according to the stop symbol of the special symbol 192 and the variation pattern of the special symbol 192.

  The stop mode of the effect symbol 190 is formed as a combination of three effect symbols 190. In the case of a big hit, that is, a transition to a special game, three identical effect symbols 190 such as “7, 7, 7” and “1, 1, 1” are stopped and displayed side by side. When it is a probable hit, the effect symbols 190 indicating the same odd number are arranged. That is, in the case of the probability variation, any one of “1, 3, 5, and 7” is stopped side by side. On the other hand, in the case of a normal hit, three of “2, 4, 6” are stopped side by side.

  When the determination result by the winning / failing lottery means 112 indicates that the game does not shift to the special game, a combination that does not have the three effect symbols 190 such as “3.1, 2” and “9,4,6” is selected. The However, if the determination result is that the game does not shift to the special game, and the variation pattern of the special symbol indicating the detachment with reach is selected, “1 • 9 • 1” or “7 • 2 • 7 ”, a combination in which only one effect symbol 190 is not aligned is selected. In the moving image reproduction process by the effect pattern, a moving image other than the fluctuation display of the effect symbol 190 is also reproduced. For example, the player's sense of expectation for the jackpot may be aroused by playing a special video that suggests the possibility that the change is a hit variation. In an effect mode called so-called super reach or the like, various animations and live-action moving image reproduction are often performed in addition to the change display of the effect symbol 190.

  In the pachinko gaming machine 10 according to the present embodiment, the effect symbol 190 is displayed so as to be more conspicuous than the special symbol 192. Therefore, the player recognizes the success / failure based on whether or not the same number of effect symbols 190 are arranged, and recognizes the success or failure of the probability change transition based on whether or not the arranged numbers are odd. The effect determining unit 132 sends information on the stop symbol and the effect pattern of the effect symbol 190 to the effect display control unit 134.

  The effect display control means 134 causes the effect display device 60 to display an effect image including the effect symbol 190 as a moving image in accordance with the selected effect pattern. The effect display control means 134 further controls effect processing such as lighting and extinguishing of the game effect lamp 90 and sound output from the speaker 18.

The effect data storage means 130 includes special effect data storage means 131. The special effect data in this embodiment is effect data for so-called mission effects. The special effect data is not limited to the mission effect, and any effect may be used as long as the effect period is a period that can include a plurality of special symbols. For example, it may be an effect that the display content is developed as a story based on a predetermined scenario over a plurality of variable display periods.
A specific effect mode will be described later in detail with reference to FIGS. 4 (a) and 4 (b).

  The effect display control means 134 includes special effect execution means 135. The special effect execution means 135 executes the mission effect according to the special effect data when a predetermined game condition (hereinafter referred to as “mission start condition”) is established. The mission start condition is randomly established with a predetermined probability at the start of symbol variation. Also, the mission start condition may be a condition that is established at a higher probability at the time of starting the symbol variation that is a big hit than at the time of starting the symbol variation that is out of place. According to such an aspect, it becomes easier to evoke the player's expectation for the jackpot due to the start of the mission effect.

At the time of executing the mission effect, for example, a predetermined “guarantee condition” such as “determined if you reach 2 within 10 revolutions” is displayed. The guarantee condition here includes two elements, a period of “within 10 revolutions” and a display mode of “2 reach”. The period presented as the guarantee condition is called “mission period”, and the display mode is called “guaranteed image”. That is, when the guarantee image “reach 2” is displayed during the mission period “within 10 revolutions”, the guarantee condition is satisfied. In the case of the above example, if “2 reach” is displayed during the symbol variation period of 10 times including the symbol variation at the time of guarantee condition presentation, the jackpot is confirmed.
When a jackpot occurs during the mission period, the effect determining means 132 selects the effect pattern indicating the jackpot after displaying the guarantee image. By such control, an effect mode is realized as if it was a big win thanks to the establishment of the guarantee condition.

  In accordance with the instruction received from the effect display control means 134, the accessory control means 136 causes the movable accessory 140 to act in an effect manner in accordance with the effect contents in the effect display device 60 and the blinking process of the game effect lamp 90.

  A unique feature of the pachinko gaming machine 10 in this embodiment is to change the mission period as appropriate according to the gaming state. Specifically, the length of the mission period is determined based on either “the amount of incoming balls” or “the rate of change”. When the mission start condition is satisfied, the special effect execution means 135 first selects whether the mission period should be determined based on the amount of incoming balls or the rate of change. A specific method for determining the mission period will be described later in detail with reference to FIGS. Before that, the amount of entering balls and the fluctuation rate will be described.

The number of entering balls measuring means 126 measures the number of entering the starting opening 62 per predetermined time as “incoming quantity”. In the present embodiment, the number of balls entering the start port 62 in the latest 30 minutes, that is, the period from 30 minutes before to the present time is measured as the amount of balls entered. In addition to this, the following definition can be considered as the amount of entrance.
1. Probability that a game ball that has been launched enters the start port 62 at a predetermined measurement time. For example, the number of game balls that have been launched in the last 30 minutes is 3000. If the number of detected balls is 162, 162 ÷ 3000 × 100 = 5.4 (%) may be calculated as the amount of entering balls.
2. For each of a plurality of measurement periods, the average value of the number of balls entered into the start port 62. For example, the number of balls entered from 30 minutes before to the current time is 110, and the number of balls entered from 60 minutes before to 30 minutes is 130. If there is, the average value of 120 balls may be calculated as the amount of entrance.
3. Number of winning / not-win lottery values acquired in a given measurement period For example, even if the number of balls entered into the start port 62 in the last 30 minutes is 120, some of these may be so-called invalid prizes. unknown. Therefore, the number of valid winnings in the measurement period may be calculated as the amount of balls received by subtracting the number of game balls that have become invalid winning. According to such an aspect, it is possible to calculate the number of times that the winning / throwing lottery value is actually acquired, that is, the number of times that a chance to become a big hit is provided, as the amount of entered balls, not the degree of entering the starting port 62.
4). For example, when the symbol variation is started 60 times in the latest 30 minutes, “60” may be acquired as the amount of entered balls. In this case, the above 3. A value close to is often acquired as the amount of entrance.
In any case, the amount of incoming balls may be a value that directly or indirectly indicates the amount of incoming balls to the start port 62. When the amount of incoming balls is large, it can be said that the game is progressing smoothly. Therefore, the amount of incoming balls can be an index value indicating the progress of game progress, in other words, the game progress pace. In addition, in order to expect accuracy as an index, the execution period of special games may be excluded from the measurement target.

The fluctuation rate calculation means 128 calculates the ratio of the period in which the symbol fluctuation is made out of the predetermined measurement period as the “fluctuation rate”. In the present embodiment, the ratio of the time in which the symbol variation is made in the last 30 minutes is calculated as the variation rate. For example, if the length of time during which the symbols have changed in the last 30 minutes is 24 minutes, the rate of change is 24 ÷ 30 × 100 = 80 (%).
As long as the holding control means 116 holds the holding ball, new symbol variations are started one after another. However, when the reserved ball becomes zero, a period in which the symbol does not change (hereinafter referred to as “non-change period”) occurs. In order not to generate the non-variable period, the player needs to continuously enter the starting port 62. The fluctuation rate is not the ease of entering the starting port 62 but the ratio of the symbol fluctuation period, which is a period in which the player can actually expect a big hit from the viewpoint of the player, to the entire game period. If a long production pattern such as Super Reach happens to occur, although the amount of entrance is small, it is easy for the player to feel that the game is progressing smoothly. Therefore, the fluctuation rate can also be an index value indicating the smoothness of the game progress as seen by the player. In addition, in order to expect accuracy as an index, the execution period of special games may be excluded from the measurement target.

The special effect execution means 135 determines the mission period according to the entrance rate and the change rate. It is desirable to measure and calculate the entrance rate and variation rate as a separate process from the main process such as symbol variation.
It should be noted that the amount of entered balls and the rate of change cannot be acquired until a predetermined measurement period elapses after the power is turned on. For this reason, the mission may not be executed until a predetermined measurement period elapses after the power is turned on. Or, record the amount and rate of change of the ball that was measured in the past, and after the power is turned on, the mission period will be extended according to the amount of ball and the rate of change measured in the past until the predetermined measurement period elapses. It may be determined.

FIG. 4A is a screen diagram showing a display form of a mission effect in which an effect period is defined by the number of changes.
The mission effect screen 208 is displayed when a mission start condition is established at the start of symbol variation, and presents a guarantee condition that is a condition for the mission to be established in the guarantee condition display area 206.
In the guarantee condition display area 206 in the same figure, the guarantee conditions are shown as the mission period “within 10 rotations” and the guarantee image “2 stops in the left fluctuation sequence”. The player wishes that “2” stops in the left variation column before the number of variations of the special symbol and the effect symbol reaches 10. By presenting a guarantee condition that “the jackpot will be determined if“ 2 ”stops in the left variation column”, it is possible to exert the effect as if the possibility of jackpot is increased.

FIG.4 (b) is a screen figure which shows the display aspect of the mission effect by which an effect period is prescribed | regulated by time.
The mission effect screen 208 shown in the figure is also displayed when the mission start condition is established at the start of symbol variation, and the guarantee condition is presented in the guarantee condition display area 206.
In the guarantee condition display area 206 shown in the figure, the guarantee condition is shown as a mission period “within 5 minutes” and a guarantee image “reach in the left and right fluctuation columns”. The player wishes that a reach is established in the left variation column and the right variation column until five minutes have elapsed since the mission effect was started. By presenting the guarantee condition that “the jackpot is determined as long as reach is established in the left and right fluctuation trains”, it is possible to exert a production effect as if the possibility of jackpot increases.

The mission effect in which the mission period is defined by the number of fluctuations as shown in FIG. 4 (a) is the “number-type mission effect”, and the mission effect in which the mission period is defined in time as shown in FIG. 4 (b). This is called “time-based mission production”. When the mission start condition is satisfied, the special effect execution means 135 randomly selects which of the number-type mission effect and the time-type mission effect is to be executed. The effect display control means 134 randomly selects whether to determine the mission effect based on the amount of incoming balls or to determine the mission period based on the rate of change. Therefore, the mission direction is
1. 1. Time-based mission production that determines the mission period based on the amount of incoming balls. 2. Number-of-times mission effect that determines the mission period based on the amount of incoming balls. 3. A time-based mission effect that determines the mission period based on the rate of change. There are four types of mission-type mission effects that determine the mission period based on the rate of change. Above 1.2. In this case, the special effect execution means 135 determines the mission period with reference to the first period table 210 shown in FIG. 3.4. In this case, the special effect execution means 135 determines the mission period with reference to the second period table 230 shown in FIG.
Furthermore, two settings are prepared: a setting A in which the mission period becomes longer as the amount of incoming balls and the rate of change are larger, and a setting B in which the mission period becomes longer as the amount of incoming balls and the rate of change are smaller. Setting A and setting B are switched according to the player layer that is the target of the pachinko gaming machine 10.

Setting A: The mission period becomes longer as the amount of entering balls and the fluctuation rate are larger. The setting A is a setting for a player who is more interested in the progress of the game substantially than the content of the production, in other words, a player with a lot of gaming experience (hereinafter referred to as “skilled player”).
When it is difficult to enter the starting port 62 or when a non-variable period is likely to occur, the player is likely to feel that the progress of the game is slow. In such a situation, if a long mission effect such as “100 rotations” or “20 minutes” is executed, it is easy for the skilled player to make the game as a whole for the purpose of being substantially viewed. Rather, when the progress of the game is slow, it is easier to connect the player's interests in the game by changing short-term mission effects repeatedly rather than executing one mission effect for a long time. It is done.
Therefore, by shortening the mission period when the amount of entrance and the rate of change are small, and by executing a long mission effect when the rate of entry and the rate of change are large, that is, when the game progresses quickly, a skilled player Continue to play games.

Setting B: A setting in which the mission period becomes longer as the amount of incoming balls and the fluctuation rate are smaller. The setting B is a setting intended for a player who is likely to be interested in the contents of the production, in other words, a player who has not so much gaming experience (hereinafter referred to as “unskilled player”).
When it is difficult to enter the starting port 62 or when a non-variable period is likely to occur, the player is likely to feel that the progress of the game is slow. If a short mission effect such as “3 rotations” or “30 seconds” is executed in such a situation, it is difficult for an unskilled player to establish a guarantee condition within such a short mission period. It may give an impression. Rather, when the progress of the game is slow, it is considered that it is easier to evoke the expectation of the unskilled player on the jackpot by executing the mission effect in which the long mission period is set.
Therefore, when the amount of incoming balls and the rate of change are small, the mission period is lengthened, and when the rate of entrance and the rate of change are large, that is, when the progress of the game is fast, a short mission effect is executed. It becomes easy to improve the effect of the mission production for the person.

FIG. 5 is a diagram illustrating a data structure of the first period table 210.
The number of balls entered 212 indicates the number of balls entered into the start port 62 in the last 30 minutes as the amount of balls entered. A setting A column 214 and a setting B column 216 indicate the mission periods in the setting A and the setting B, respectively. The time type column 218 indicates the mission period of setting A: time type mission effect. The number-of-times column 220 shows the mission period of setting A: number-of-times mission effect. The time type column 222 indicates the mission period of setting B: time type mission effect. The frequency type column 224 indicates the mission period of setting B: frequency type mission effect.

  The pachinko gaming machine 10 in the present embodiment is designed so that normally 150 balls per 30 minutes enter the start opening 62 when hitting is continued. However, the number of incoming balls per 30 minutes is not necessarily constant depending on the skill of the player, individual differences, aging, or whether the time is short. In particular, since the start port 62 is easy to expand during the time reduction, the amount of entering balls increases as a result. The first period table 210 is a table for selecting an optimal mission period from the amount of balls that changes according to the player, gaming machine, gaming state, and the like. The special effect execution means 135 determines the mission period with reference to the first period table 210 when determining the mission period based on the amount of incoming balls. The special effect execution means 135 may determine the mission period at the start of the mission, or may change the mission period after the mission starts.

  When the mission period is changed after the mission starts, the amount of incoming balls may be measured using a short period such as 1 minute instead of a long period of 30 minutes. For example, if the average length of the mission effect is 5 minutes, the amount of incoming balls from 1 minute to 2 minutes after the mission effect is started is measured. Then, the length of the mission effect may be determined during the execution of the mission effect according to the amount of entered balls. For example, when 5 balls are entered in one minute, since 5 × 30 = 150 per 30 minutes, the mission period is set as “5 minutes” or “4 times” in the case of setting A. .

FIG. 6 is a diagram illustrating a data structure of the second period table 230.
The change rate column 232 indicates the change rate in the last 30 minutes. The setting A column 234 and the setting B column 236 show the mission periods according to the setting A and setting B, respectively. The time type column 238 indicates the mission period of setting A: time type mission effect. The frequency type column 240 shows the mission period of setting A: frequency type mission. The time type column 242 indicates the mission period of setting B: time type mission effect. The number of times type column 244 indicates the mission period of setting B: number of times type mission effect.

  The pachinko gaming machine 10 in the present embodiment is usually designed to have a variation rate of 70% to 80% when the ball is continuously hit. However, the rate of change is not necessarily constant due to the skill of the player, individual differences, secular changes, selected change patterns, and the like. As it happens, if a long-time production pattern such as super reach is continuously selected, the rate of change increases. The second period table 230 is a table for selecting an optimal mission period from the rate of change that changes according to the player, gaming machine, gaming state, and the like. The special effect execution means 135 determines the mission period by referring to the second period table 230 when determining the mission period based on the change rate. The special effect execution means 135 may determine the mission period at the start of the mission, or may change the mission period after the mission starts.

  In calculating the amount of incoming balls and the rate of change, the execution period of special games may be excluded from the measurement period. Further, the period during which the hit ball is stopped may be excluded from the measurement period. In the present embodiment, the amount of incoming balls and the mission period, or the variation rate and the mission period are associated in a table format. As a modification, the mission period may be set by a predetermined function with the amount of incoming balls and the variation rate as variables. For example, it may be calculated as mission period (minutes) of time-type mission effect = number of entered balls ÷ 30.

FIG. 7 is a flowchart showing a basic operation process in the pachinko gaming machine 10.
The process shown in the figure is a process repeatedly executed as a loop process. First, a winning process is executed when a game ball wins the starting port 62, the general winning port 72, the big winning port 66, etc., or when the game ball passes through the operation port 68 (S10), and it must be in a special game. If the special game lottery is executed (S14), the special game control process is executed (S14). If the special game is in progress (Y of S12), the special game control process is executed (S16). Award ball payout according to various winnings in the processing up to S16 is processed (S18).
The number-of-entrance counting means 126 and the fluctuation rate calculating means 128 always measure the amount of incoming balls and the fluctuation rate as a process different from the process shown in FIG.

FIG. 8 is a flowchart showing in detail the normal game control process of S14 in FIG.
In the normal game control process, if the winning / losing lottery value is on hold (Y in S30) and the symbol variation is not being displayed (N in S32), the winning / losing lottery means 112 executes the determining process. (S34). Details of the success / failure determination process will be described with reference to FIG. The main display control means 118 starts the variable display of the special symbol 192 and transmits a change start command to the sub-board 104. Receiving this, the effect determining means 132 selects the effect pattern, and the effect display control means 134 starts the variable display of the effect symbol 190 (S36).

  Next, the special effect execution means 135 determines whether the mission start condition is successful (S100). The special effect execution means 135 determines whether or not the mission start condition is successful by lottery on the condition that the mission effect is not being performed. When the mission start condition is satisfied (Y in S100), the special effect execution means 135 selects a mission effect type (S102). First, the special effect execution means 135 randomly selects whether to determine the mission period based on the amount of incoming balls or the rate of change. The mission period is determined by the first period table 210 when based on the amount of incoming balls, and by the second period table 230 when based on the variation rate. Further, the special effect execution means 135 selects either the number-type mission effect or the time-type mission effect.

  The special effect execution means 135 selects a mission effect period by referring to the first period table 210 or the second period table 230 according to the type of mission effect and the setting A / B (S104). The special effect execution means 135 displays the mission effect screen 208 on the screen, and starts the mission effect by indicating the guarantee condition in the guarantee condition display area 206 (S106). If the mission start condition is not satisfied (N in S100), the processing from S102 to S106 is skipped.

  If the winning / losing lottery value is not held in S30 (N in S30), the processing from S32 to S106 is skipped, and if the symbol is changing in S32 (Y in S32), the processing from S34 to S106 is performed. Processing is skipped. If the symbol variation has already started (Y in S38), the symbol variation display process is continued (S40). When the symbol is not changing (N of S38), the process of S40 is skipped.

  Note that the special effect execution means 135 may change the mission period after the mission effect starts. For example, in the case of the number-type mission effect, the guarantee condition is displayed as, for example, “within X minutes” while the mission period is indefinite at the start of the mission effect. Then, after starting the mission effect, the processing shown in S104 may be executed at a predetermined timing to determine the mission period, and the mission period may be clearly indicated in the guarantee condition display area 206. Alternatively, at the time of starting the mission effect, for example, even if the temporary mission period is indicated as “within 10 minutes” and the process shown in S104 is executed at a predetermined timing after the mission effect starts, the mission period is fixed. Good.

FIG. 9 is a flowchart showing in detail the success / failure determination process in S34 of FIG.
First, the success / failure lottery means 112 performs a success / failure determination of the success / failure lottery value read from the hold control means 116 (S50). If the probability change is in progress, the accuracy change determination table is used. If it is a big hit (Y of S52), the special game control means 120 turns on the special game flag (S54). When the special game flag is on, the special game is executed after the end of the change.

If it is a probability change hit (Y in S58), the specific game executing means 122 turns on the probability change flag (S60). When the probability variation flag is on, the success / failure lottery executed after the symbol variation is executed by the probability variation success / failure table. After the special game is executed by turning on the special game flag in S54, the probability change game is executed by turning on the probability change flag in S60. If it is a normal hit (N in S58), the specific game executing means 122 turns off the probability variation flag (S62). When the probability variation flag is off, the success / failure lottery executed next to the symbol variation is executed by the non-probability variation success / failure table. After the special game is executed by turning on the special game flag in S54, the fluctuation shortening game is executed by turning off the probability change flag in S60.
If the winning / losing lottery is off (N in S52), the special game control means 120 turns off the special game flag (S56).

FIG. 10 is a flowchart showing in detail the special game control process in S16 of FIG.
A special game is a game that is executed after a symbol change when the winning or failing lottery is won and the special game flag is turned on. First, if the special winning opening 66 has not been opened (N in S70), the production display control means 134 starts the special game production process (S72), and the open / close control means 124 opens the special winning entry 66 (S74). .
If the big winning opening 66 has been opened, S72 and S74 are skipped (Y in S70). When the predetermined opening time has elapsed since the grand prize opening 66 was opened (Y in S76), or the opening time has not elapsed (N in S76), there are nine or more game balls to the big winning opening 66 When the player has entered the ball (Y in S78), the opening / closing control means 124 closes the special winning opening 66 (S80). If the opening time has not elapsed (N in S76) and the number of balls entered into the grand prize winning opening 66 has not reached nine or more (N in S78), the processing after S80 is skipped and the flow of S16 Exit.

If the number of rounds of the unit game has reached 15 after closing the special winning opening 66 in S80 (Y in S82), the effect display control means 134 ends the effect processing of the special game (S84), and the special game control means 120 ends the special game (S86). Note that when it is a probable change, the specific game executing means 122 sets a probable change success / failure table as a success / failure table for the success / failure lottery. In the case of a normal hit, the specific game execution means 122 starts a variation shortening game.
If the number of rounds has not reached 15 (N in S82), 1 is added to the number of rounds, and the flow in S16 is terminated (S90).

  As described above, according to the pachinko gaming machine 10 shown in the present embodiment, the length of the mission period can be controlled in accordance with the amount of balls entered and the rate of change. If the main board 102 notifies the sub-board 104 of the start winning information, the acquisition timing of the pass / fail lottery value, the fluctuation start timing, the fluctuation end timing, etc., it is possible to measure and calculate the amount of balls and the fluctuation rate on the sub board 104 side. It is. In this embodiment, the number-of-balls measurement unit 126 and the variation rate calculation unit 128 are described as being mounted on the sub-board 104. However, the number-of-balls measurement unit 126 and the variation rate calculation unit 128 are the main substrate 102. May be implemented.

  The mission effect is executed to increase the player's sense of expectation for the jackpot. Originally, the longer the mission period, the more impression can be given to the player that the guarantee condition is more likely to be established. However, it is necessary to interweave not only the long mission effect but also the short mission effect in order to fully exhibit the effect of the long mission effect.

  In addition, for the skilled player who enjoys the mission effect as a kind of effect, and for the unskilled player who pays close attention to the success or failure of the guarantee conditions, the effect of the mission effect is quantitative and qualitative. It must be different.

  In the case of a skilled player, it is considered that executing a long mission effect when the pace of game progress is slow will adversely affect the gaming effect. Therefore, the pachinko gaming machine 10 that targets the skilled player is set to A. On the other hand, in the case of an unskilled player, when the game progress pace is slow, it is desirable to execute a long mission effect effective for giving an impression that the guarantee condition is likely to be satisfied. For this reason, the pachinko gaming machine 10 that targets unskilled players may be set to the setting B. Then, by adjusting the mission period according to the amount of entrance and the rate of change suggesting the game progress pace, a suitable mission period corresponding to the individual difference, the player, and the gaming state can be dynamically selected.

  In the above, this invention was demonstrated based on the Example. This embodiment is merely an example, and it will be understood by those skilled in the art that various modifications can be made to the combination of each component and each processing process, and such modifications are also within the scope of the present invention. is there.
