Description

  The present invention relates to a ball game machine such as a pachinko game machine, and more particularly to a technique for improving the game performance of a ball game machine.

  Various types of pachinko machines are popular as bullet ball machines. Some conventional pachinko machines have random lottery values acquired as a result of a game ball falling into a starting port formed on the game board. The acquired lottery values are temporarily stored, for example, up to four as reserved balls. The reserved balls are sequentially read out one by one to determine whether or not they are correct, and a symbol called a special symbol is variably displayed according to the determination result. At this time, there is a case where a design for the effect purpose called a decorative design is displayed in a variable manner in conjunction with the display of the special design. Based on the lottery result based on the read lottery value, the stop display mode of the special symbol is determined.

When the special symbol is stopped and displayed in a specific manner after the fluctuation display for a predetermined time, 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 temporarily 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 mainly for the purpose of opening a special winning opening in order to obtain many prize balls, that is, shifting the game state to a special game (see, for example, Patent Document 1).

  Some of the ball game machines transition to a game state advantageous to the player, which is also called “probability change” even after the special game is finished. Since the winning range of the lottery value is expanded in this probability variation state, the probability variation state is easier to shift to a special game than the non-probability variation state. Of the hits, if a hit with probability variation is entered, the probability variation state is obtained.

In the case of such a ball game machine,
1. Whether or not
2. Whether or not it is even more probable on the condition that it is a hit,
It can be said that these two game elements are determined by the lottery method.
JP 2003-230714 A

  Therefore, in addition to the rearrangement of such lottery contents and the transition to normal special games (hereinafter referred to as “first special game”) (hereinafter referred to as “normal winning”), the first special A ball and ball game machine that is set to a special game (hereinafter referred to as “second special game”) that is designed to reduce beneficiary than the game (hereinafter referred to as “second special game”) is considered. It is done. The second special game may be designed as a game that is substantially impossible to benefit. Even if it is per omission, the player can expect a future transition to the first special game if there is a certainty. The difference between the two types of clarification will be clarified, assuming that the most recent beneficiary with a normal hit is the most reliable beneficiary and the omission with certainty is a hit with future beneficiary potential.

  In the case of the above design, it can be said that the merit for the player is small even if it is already in the probability variation state even if it is omitted with probability variation. Therefore, the present inventor has recognized that the occurrence of omission with probability variation when in the probability variation state may cause the player to feel even an uncomfortable feeling that has been wasted luck. Therefore, the present inventor has come up with the idea that the game performance can be improved while coping with such a problem by controlling the contents of the presentation according to the game situation at the time of occurrence of omission.

  The present invention is an invention completed based on the above recognition by the present inventor, and its main object is to provide an effect control technique for suitably improving the game performance in a ball game machine in which the hit probability can be varied. It is in.

One embodiment of the present invention is a ball game machine.
This gaming machine is provided at a predetermined position in the game area with a game area formed thereon, a start opening for entering a game ball, and provided at a predetermined position in the game area so that a game ball can enter A variable pitching device that can be opened to a certain state, a lottery means for performing lottery to determine about multiple types of hits when a game ball has entered the start opening, and a trigger for the lottery execution The symbol display means for variably displaying, and when the result of the lottery is the first of a plurality of types of winning, the variable pitching device is released after the symbol variability display is stopped, which is advantageous to the player. Special game control means for executing a special game, and when the lottery result is the second or third win among a plurality of types, the symbols are displayed after a lapse of a predetermined period after the change display of the symbols is stopped. Usually the fluctuation time of And a time setting control means for changing the setting to a short variation time, and when the lottery result is the second, the winning probability of the lottery after the lapse of the predetermined period is set to a low probability, and when the lottery is the third, the predetermined period Probability setting control means for setting the probability of winning the lottery after the passage to a high probability, and effect display means for displaying an effect image for visually producing the result of the lottery as a moving image.
The effect display means sets the winning probability of the lottery as the same effect as when the third winning occurs even if the second winning occurs when the winning probability of the lottery is set to a low probability Even if a third win occurs when a high probability of winning the lottery is set and a promotion expectation effect suggesting the possibility of changing is set, the same effect as when the second win occurs As a result, a relegation crisis effect that suggests the possibility that the winning probability of the lottery is changed to a low probability is executed.

In a variable pitching device, an unfavorable state for a player may mean a closed or narrow state where an entrance for a game ball should enter, and an advantageous state for a player means that the entrance is open. A state or a relatively wide state may be indicated.
The effect display means may select an effect pattern that defines a moving image reproduction process of the effect image with reference to a data table that specifies selection probabilities of various effect patterns. The data format may be a data format managed in a so-called array format or list format, for example. In this specification, the “table” may indicate two or more types of data recorded in the storage area of the memory in a format in which the other data corresponding to one data can be specified, or a recording format thereof. .

  According to such an aspect, the player's sense of expectation for the transition to high probability (hereinafter referred to as “promotion”) regardless of whether the second or third hit occurs in the low probability state. The promotion expectation production for arousing is performed. For this reason, the promotion expectation effect can evoke the player's expectation for promotion in a form that incorporates the player's concerns regarding the promotion failure. Similarly, if either the second or third hit occurs in a high-probability state, a demotion crisis to raise the player's anxiety about the transition to the low probability (hereinafter referred to as “demotion”) Production is performed. For this reason, the relegation crisis production can arouse the player's anxiety about the demotion in the form of leaving the player's desire for high probability maintenance. By such a production method, it is possible to effectively change the player psychology with respect to the probability fluctuation.

  The special game control means may open the variable pitching device a predetermined number of times in a predetermined period when the result of the lottery is the second hit or the third win.

  According to such an aspect, even when the lottery result is the second hit or the third win, the player can cause the game ball to enter the variable pitching device. Alternatively, at the time of the second hit or the third hit, the opening time of the variable pitching device is shortened or the number of times of opening is set to be small so that it is substantially difficult to enter the game ball into the variable pitching device. May be.

  The effect display means continues the promotion expectation effect until the next first occurrence, and in the case of the promotion expectation effect triggered by the occurrence of the second hit, determines the end point of the promotion effect based on the second occurrence point Even before the next first hit occurs, the promotion expected effect may be ended when the promotion effect end point is reached.

  According to such an aspect, the promotion expectation effect when the promotion is not actually promoted, which is executed when the second hit occurs, is the end of the predetermined promotion effect even before the next first hit occurs. It will end when the time is reached. The promotion effect end time may be set, for example, when the number of symbol fluctuations after the second hit has reached a predetermined number of times or after a predetermined time has elapsed. On the other hand, the expected promotion effect when the promotion is actually executed, triggered by the occurrence of the third hit, may be continued until the next first hit regardless of the end of the promotion effect. According to such an aspect, the player's interest can be aroused with respect to whether or not the promotion expected effect continues for a long period of time.

  The effect display means may set the end point of the promotion effect on the basis of the new occurrence time of the second hit when a new second hit occurs during the execution of the expected promotion effect.

  According to such an aspect, for example, when the second hit occurs again during the promotion expectation effect triggered by the second hit, the promotion expectation effect was originally scheduled even though the promotion was not actually promoted. It will be extended beyond the end of the production. Further, when the third hit occurs during the promotion expected effect triggered by the second hit, the promotion expected effect may be continued until the next first hit occurs. According to such an aspect, even if the promotion is not actually promoted, the promotion expectation effect can be continued for a long period of time. Therefore, there is an effect in further enhancing the game entertainment about the length of the promotion expectation effect.

  The effect display means determines the end point of the demotion production that should end the demotion crisis production based on the second or third occurrence time as a trigger for the execution of the demotion crisis production. When the third hit is newly generated, the demoteing effect end time may be reset based on the new occurrence time of any one of them.

  According to such an aspect, when the second hit or the third hit occurs during the demote crisis effect, the execution period of the demote crisis effect becomes longer than the originally scheduled demote effect end time. Therefore, when the length of the relegation crisis production is extended, there is an effect of further stimulating the player's sense of tension against the relegation.

Another aspect of the present invention is also a ball game machine.
This ball-and-ball game machine is provided at a predetermined position in the game area with a game area formed therein, a start opening through which a game ball can enter, and at a predetermined position in the game area. Triggered by a variable pitching device that can be released into a ballable state, lottery means for performing lottery in order to determine a plurality of types of hits when a game ball has entered the start opening, and lottery execution As a symbol display means for variably displaying symbols, and when the lottery result is the first of a plurality of types of hits, the variable pitching device is released after the variable display of the symbols is stopped, to the player Special game control means for executing advantageous special games, and when the result of the lottery is the second or third win among a plurality of types, after the lapse of a predetermined period after the change display of the symbols is stopped Through the design variation time Time setting control means for changing the setting to a shorter variation time, and when the lottery result is the second, the winning probability of the lottery after the lapse of the predetermined period is set to a low probability, and when the lottery is the third, the predetermined period The probability setting control means for setting the winning probability of the lottery after elapse of time and the effect display means for displaying the effect image for visually producing the result of the lottery as a moving image.
The effect display means sets the probability of winning the lottery as the same effect as when the third winning occurs even if the second winning occurs when the winning probability of the lottery is set to a low probability The promotion expectation effect that suggests the possibility of being changed continues until the next first hit occurs, and in the case of the promotion expected effect triggered by the occurrence of the second hit, before the next first hit occurs Even if there is, the promotion expected effect is terminated when a predetermined promotion effect end point determined based on the second occurrence point is reached.

  Even in such a mode, when either the second or third hit occurs in the low probability state, the promotion expected effect is executed. For this reason, the promotion expectation effect can evoke the player's expectation for promotion in a form that incorporates the player's concerns regarding the promotion failure. Further, in the case of a promotion expected effect that is executed with the occurrence of the second hit as an opportunity, it ends when a predetermined promotion effect end point is reached even before the next first hit occurs. The promotion effect end time may be set, for example, when the number of symbol fluctuations after the second hit has reached a predetermined number of times or after a predetermined time has elapsed. According to such an aspect, the player's interest can be further aroused whether or not the promotion expectation effect continues for a long period of time.

  It should be noted that any combination of the above-described constituent elements, or the constituent elements and expressions of the present invention are mutually replaced between methods, apparatuses, systems, computer programs, recording media storing computer programs, data structures, and the like. This is effective as an embodiment of the present invention.

  According to the ball game machine of the present invention, it is effective to improve the game performance of the ball game machine by suitably controlling the effect display according to the game situation.

FIG. 1 is a schematic diagram for showing the relationship between the gaming states of the pachinko gaming machine shown in the present embodiment.
The basic specifications of the pachinko gaming machine in this embodiment are as follows.
1. The game state is roughly divided into “normal game” and “special game”. When a special symbol lottery, which will be described in detail later, is won, the game shifts from a normal game to a special game. During normal game execution, the player hits a game ball for the purpose of shifting to a special game. After the special game ends, the game returns to the normal game.
2. Normal games are roughly divided into a “low probability state” and a “high probability state”. In the high probability state, the probability of winning the special symbol lottery is set to a high probability, so that it is easy to shift to the special game.
3. There are two types of special symbol lottery results: winning and losing. There are two types of hits: “normal hits” and “per abbreviations”. In the case of normal winning, the game moves to the first special game, and in the case of omission, the game moves to the second special game. The second special game is a special game whose duration is less than 1 second. Therefore, the player cannot expect a prize ball from the second special game.
The normal hit is always a hit with certainty. Therefore, after the end of the first special game, the game shifts to a normal game as a high probability state. On the other hand, there are two types of omissions: “per probability omission per omission” with probability change and “non-probability omission per omission” that is not omission. Once the transition to the high probability state is made, there is no transition to the low probability state unless a non-probability change omission occurs.
In summary, there are four types of special symbol lottery results: “normal per (with probability variation)”, “per probability variation omitted”, “non-probability omitted per”, and “out”.
4). When the special symbol lottery is won, the fluctuation shortening game, so-called time saving, continues for a while in the normal game after the special game is finished. Therefore, more strictly, the low-probability state is further divided into “normal low-probability state (hereinafter referred to as“ normal low-probability state ”)” and “low-probability state during execution of a variable shortening game (hereinafter“ time-short low-probability state ”). ")"). On the other hand, the high probability state is also classified as “normal high probability state (hereinafter referred to as“ normal high probability state ”)” and “high probability state during execution of variable shortening game (hereinafter referred to as“ short-time high probability state ”)”. being classified. The variation shortening game is generated by every hit. The fluctuation shortening game will be described in detail later.

FIG. 2 shows a basic structure on the front side of the pachinko gaming machine.
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 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 a button operated by the player to input a predetermined instruction on the gaming machine side. 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 opening 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 normal electric accessory at the start opening. 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 as a “win” when the special symbol 192 stops in a predetermined manner. The big winning opening 66 is provided above the out opening 58 and the like. The inside of the special winning opening 66 is divided into a specific area (so-called V zone) and a general area. The winning detection device 78 of the big winning opening 66 includes a sensor that detects passage of a game ball through a specific area and a sensor that detects passage of a general area.

  The special symbol display device 61 and the effect display device 60 provided substantially in the center of the game area 52 display the variation of the effect image including the special symbol 192 and the decorative symbol 190 linked to the special symbol 192 on each screen ( Hereinafter, such display is referred to as “symbol change” or “change display”). In the effect display device 60, an effect image separate from the decorative symbol 190 is also displayed. The special symbol 192 is a symbol corresponding to the result of a lottery (hereinafter referred to as “special symbol lottery”) that is triggered by the entry of a game ball into the start port 62. If the symbol pattern when the variable display is stopped is a symbol determined to be a hit, the timing at which the stop symbol is displayed is the hit occurrence timing. The special symbol display device 61 is display means composed of, for example, 7 segment LEDs. The special symbol display device 61 circulates numbers in the range of 0 to 9 as a variation display of the special symbol 192. The normal hit time is 0, the probability change omission time is 1, the non-probability change omission time is 2, and when it is off, any number from 3 to 9 is displayed as a stop symbol.

  The effect display device 60 is a liquid crystal display that displays the decorative symbol 190 in a variable manner in conjunction with the variable symbol display of the special symbol 192. The decorative symbol 190 is a symbol for visually producing the result display of the special symbol lottery indicated by the special symbol 192. The effect display device 60 displays, as the decorative symbol 190, for example, a plurality of rows of symbol variation moving images that simulate a slot machine game. The effect display device 60 is composed of a liquid crystal display, but may be composed of other display means such as a mechanical drum or LED. Since the special symbol 192 does not necessarily have a role of production, in this 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. In the case of adopting a technique in which the decorative design 190 is not displayed with the role of production, the special design 192 may be displayed on a liquid crystal display such as the production display device 60.

  The operation port 68 is provided on 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 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 the present application, “incoming”, “entering”, and “winning” include “passing”.

  When the game ball falls into the start port 62, the special symbol 192 and the decorative symbol 190 are variably displayed on the special symbol display device 61 and the effect display device 60. The variable display of the special symbol 192 and the decorative symbol 190 is stopped after the elapse of the display time determined prior to the display. When the special symbol 192 and the decorative symbol 190 at the time of the stop are symbols indicating winning, the game shifts from the normal game to the special game, and the opening / closing operation of the special winning opening 66 is started. In the pachinko gaming machine 10 according to the present embodiment, the game shifts to the first special game at the time of normal hit and to the second special game at the time of omission. Hereinafter, when these two types of special games are collectively referred to, they are simply referred to as “special games”.

First special game:
The grand prize winning opening 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 falls into a specific area while the big prize opening 66 is open, the big prize opening 66 is opened again. In this way, the opening / closing of the grand prize opening 66 is repeated up to a predetermined number of times, for example, 15 times, on condition that at least one game ball falls into the specific area while the big prize opening 66 is opened once. It is.

Second special game:
The big prize opening 66 is closed for about 0.2 seconds and then closed. After closing, after a predetermined time, for example, 0.1 second has passed, the special winning opening 66 is opened again for about 0.2 seconds, and then closed. Thus, the second special game ends. In this way, the second special game is designed as a game that is not practically advantageous to the player.

  When the normal hit or the probability change omission occurs, the game returns to the normal game in the high probability state after the first special game or the second special game. In the high probability state, a special symbol lottery is performed with a setting that has a higher probability of winning than in a normal low probability state, and a new special game is likely to occur relatively early.

  When the game ball passes through the operation port 68, a symbol called a 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 right side of the effect display device 60. The normal symbol display device 59 includes two lamps. The operation in which the respective lamps blink alternately is an operation corresponding to “ordinary symbol fluctuation display”. When the normal symbol variation display is stopped after a predetermined time has elapsed, the start port 62 is normally expanded for a predetermined time with a probability of about 50% to 80%. At this time, a predetermined one of the two lamps of the normal symbol display device 59 is turned on. During the execution of the fluctuation shortening game, the fluctuation display time of the normal symbol is shortened, and the time during which the start port 62 is opened is set relatively long.

  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 center decoration 64 is provided with a lottery holding lamp 20 at the upper part thereof and an operation holding lamp 22 at a left side part thereof. The lottery hold lamp 20 is composed of four lamps, and displays the number of special symbol lottery hold depending on the number of lights. The number of special symbol lotteries held is the number of special symbol lottery results won in the starting slot 62 during symbol variation or special game, and indicates the number of winning balls for which symbol variation has not yet been executed. 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 addition, a game effect lamp 90 is provided in the game area 52 and plays a role of production by blinking or the like.

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 success / failure lottery means 112 acquires a random number value as a success / failure 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. For example, the success / failure lottery value is acquired from a 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, a determination result of winning or losing is associated with a lottery value, and the success / failure probability is determined according to the associated winning range setting.

  The success / failure lottery means 112 refers to a success / failure determination table with a low probability in the low probability state (hereinafter referred to as “non-probability change validity determination table”), and in the high probability state, the success / failure determination with a high probability. Refer to a table (hereinafter referred to as a “probability variation determination table”). In the uncertain variation determination table, it is determined that a winning lottery value in the range of 0 to 255 is a win. In the probability variation determination table, it is determined that a winning lottery value in the range of 0 to 2500 is a win. The success / failure lottery means 112 executes a special symbol lottery by referring to any of the plurality of 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 the special symbol 192 on the special symbol display device 61 by a variable display. In addition, the decorative symbol 190 that shows the determination result by the success / failure lottery means 112 in an effect manner is variably displayed on the effect display device 60.

The symbol determination means 114 determines the stop symbol and display pattern of the special symbol 192 to be displayed on the special symbol display device 61. The symbol determining unit 114 determines a special symbol display pattern according to a pattern lottery value generated in the range of 0 to 255. Moreover, the symbol determination means 114 determines the stop symbol aspect of a special symbol according to the symbol lottery value produced | generated in the range of 0-255. When the winning / losing lottery value is a win, the symbol lottery value determines whether it is a normal hit, a probability variation omitted per unit, or a non-probable variation omitted per unit. 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 relationship between the symbol lottery value and the winning type will be further described in detail with reference to FIG.
The symbol determination means 114 also determines the stop symbol of the normal symbol to be displayed on the normal symbol display device 59 by the normal symbol lottery. The symbol determination unit 114 sends the data indicating the display pattern and the stop symbol to the main display control unit 118 and the effect determination unit 132 as a result of the special symbol lottery.

  The symbol determination unit 114 stores a plurality of types of display patterns in which a variation mode from the start to the stop when the special symbol is variably displayed is determined. The plural types of display patterns have various fluctuation times. That is, for each display pattern, a variation time is defined for each pattern as an end condition of the symbol variation, and the variation of the special symbol is stopped when the variation time elapses.

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

  The hold control means 116 holds the winning / losing lottery value acquired by the winning / failing lottery means 112 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.

  The main display control means 118 causes the special symbol display device 61 to variably display the special symbol. The main display control means 118 transmits the change start command and the change stop command to the effect display control means 134 at the timing of starting and stopping the change display of the special symbol, thereby causing the special display by the main display control means 118 to be displayed. 192 and the variation display of the decorative symbol 190 by the effect display control means 134 are synchronized, and interlocking 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 process of the special game when the special symbol lottery is won. The probability variation executing means 122 sets the normal game after the special game to the high probability state when the normal hit or the probability change omitted hit occurs. At this time, the probability variation execution means 122 sets a probability change success / failure determination table as a success / failure determination table to be referred to by the success / failure lottery means 112 for the special symbol lottery. In principle, the high probability state is continued until the next winning occurs, and during that time, the probability of winning determination by the success / failure lottery means 112 is maintained at a high value. When the non-probability change omission occurs in the high probability state, the normal game after the end of the second special game is in the low probability state. That is, the probability variation execution means 122 sets a non-probability change determination table as a determination table to be referred to by the success / failure lotter 112 for the special symbol lottery.

The variation shortening execution means 126 executes the variation shortening game after the special game ends. In the present embodiment, the variation shortening game ends after the special game ends, assuming that the variation shortening game end condition is satisfied when the special symbol is variably displayed 20 times.
During the execution of the variation shortening game, the variation time of the special symbol is shortened. Therefore, the number of special symbol lotteries per unit time is likely to increase. Also, the variation time of the normal symbol is shortened, and the probability of winning the normal symbol lottery is set to a high probability. With such a setting, a win is relatively likely to occur during the execution of a variable reduction game.
Regardless of whether it is a normal hit, a probability change omission, or a non-probability change omission, the variable reduction game is executed after the special game ends. Therefore, even if the probability change is omitted, the player can receive at least the benefit of a variation shortening game.

  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 pattern storage means 130 holds a plurality of types of decorative symbol display patterns. The effect determining unit 132 determines the stop symbol and display pattern of the decorative symbol according to the lottery result by the success / failure lottery unit 112, the special symbol stop symbol, the special symbol display pattern, and the variation time thereof.

  The stop symbol of the decorative symbol is formed as a combination of three symbols. For example, when the determination result by the success / failure lottery means 112 indicates the transition to the first special game, three symbols such as “777” and “111” are displayed. A complete combination is selected. In the case where the determination result by the success / failure lottery means 112 indicates that the game does not shift to the first special game, a combination that does not have three symbols such as “312” and “946” is selected. However, if the determination result is that the game does not shift to the first special game, and the display pattern of the special symbol indicating the loss of reach is selected, one such as “191” or “727” is selected. Select a combination that has only one symbol. In addition, when indicating the transition to the second special game, the combination of symbols may be selected so that three consecutive numbers such as “123” and “234” are arranged, but the second special game is entered. The transition may not be clearly indicated to the player by the decorative pattern stop mode. The effect determining unit 132 sends information on the stop symbol of the decorative symbol and the display pattern to the effect display control unit 134.

  The display pattern of the decorative symbol 190 defines a variation display mode of the decorative symbol 190, that is, an effect process from the start of variation to the stop of variation of the decorative symbol 190. In the display pattern, a pattern for displaying a normal out symbol, a pattern for displaying a dismissed symbol through a reach state that will be a big win if one more symbols are aligned, and a winning symbol through a reach state are displayed. When the pattern is included. In particular, the pattern that passes through the reach state includes patterns having various fluctuation times. Each display pattern has a variation time for each pattern as an end condition of the symbol variation, and the symbol variation is stopped when the variation time elapses.

  The effect display control means 134 for controlling the display related to the effects further includes a decorative symbol display means 136 and an effect image display means 138. 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 decorative symbol display means 136 displays the decorative symbol on the effect display device 60 in accordance with the selected display pattern data.

  In the pachinko gaming machine 10 in the present embodiment, an image for production is displayed separately from the decorative symbols. For example, the background image in the effect display device 60 is a kind of effect display here. The effect image display means 138 displays an effect image such as a background, and the decorative design display means 136 displays the decorative design in a variably superimposed manner thereon. The pattern storage unit 130 also stores a plurality of types of effect patterns that define the moving image reproduction process of the effect image. The effect determining means 132 appropriately selects these effect patterns according to the gaming state. The effect image display means 138 displays the effect image as a moving image in accordance with the effect pattern thus selected.

FIG. 5 is a data structure diagram showing the relationship between the symbol lottery value and the gaming state.
As already described, when a game ball enters the start port 62, a winning / no-win lottery value is acquired in the range of 0 to 65535. At the same time, a symbol lottery value for determining the stop symbol of the special symbol in the range of 0 to 255 is obtained. When the winning / losing lottery value is a win, it is determined according to the symbol lottery value whether it is a normal hit, a probability variation omitted per unit, or a non-probable variation omitted per unit.

1. Normal win When the symbol lottery value is in the range of 0 to 165, it is normal win. That is, about 65 percent of the hits are normal hits. The special game control means 120 executes the first special game after the change display of the special symbol is stopped. The probability variation executing means 122 sets the normal game after the end of the first special game to a high probability state. The variation shortening execution means 126 executes the variation shortening game in the normal game after the end of the first special game. Therefore, the normal game after the normal hit occurs and the first special game is executed is in a short-time and high-probability state. Thereafter, when the variable shortening game end condition is satisfied, the normal high probability state is entered.

2. Probability variation omission When the symbol lottery value is in the range of 166 to 204, the probability variation omission is permissible. In other words, about 15 percent of the winnings are per chance omitted. The special game control means 120 executes the second special game after the change display of the special symbol 192 is stopped. The probability variation executing means 122 sets the normal game after the end of the second special game to a high probability state. The variation shortening execution means 126 executes the variation shortening game in the normal game after the end of the second special game. Therefore, the probability change omission occurs, and the normal game after the second special game is executed is also in a short time and high probability state. Thereafter, when the variable shortening game end condition is satisfied, the normal high probability state is entered.

3. Non-probability variation omission When the symbol lottery value is in the range of 205 to 255, it becomes non-probability variation omission. That is, about 20 percent of the wins are for non-probable omissions. The special game control means 120 executes the second special game after the change display of the special symbol 192 is stopped. The probability variation executing means 122 sets the normal game after the end of the second special game to a low probability state. The variation shortening execution means 126 executes the variation shortening game in the normal game after the end of the second special game. Therefore, the non-probability change omission occurs, and the normal game after the second special game is executed is in a time-slow low probability state. Thereafter, when the variation shortening game end condition is satisfied, the normal low probability state is set.

4). When the lottery value is wrong, it goes out regardless of the symbol lottery value. In this case, the special game is not executed, the winning probability of the special symbol lottery is not changed, and the fluctuation shortening game is not executed.

  The second special game is a kind of special game, but its duration is extremely short. The effect image display means 138 executes a special game effect which is an effect display corresponding to the first special game during execution of the first special game, but does not execute the special game effect during execution of the second special game. For this reason, the player is hardly aware of the execution of the second special game even if the omission occurs during the normal game. It can be said that the omission per unit is a special hit that has a large meaning as a chance to change probability during normal games.

FIG. 6 is a schematic diagram for explaining the relationship between the effect and the occurrence per omission in the normal game.
When the omission occurs in the low probability state, the effect image display means 138 displays the promotion expectation effect screen 140, and executes the promotion expectation effect suggesting the transition from the low probability state to the high probability state. Regardless of whether it is per probability variation omission or non-probability variation omission, the promotion aspect of the promotion expected effect is the same. Occurrence per omission in the low probability state may trigger a transition to the high probability state. Therefore, when the promotion expectation effect screen 140 is displayed, the player expects to be promoted from the low probability state to the high probability state. The effect image display means 138 may execute the promotion expectation effect as a screen that provides a warm background with a bright background, for example.

  When the omission hit occurs in the high probability state, the effect image display means 138 displays the demote crisis effect screen 142 and executes the demote expectation effect suggesting the transition from the high probability state to the low probability state. Regardless of whether it is per probability change omission or non-probability abbreviation omission, the production mode of the relegation crisis production is the same. Occurrence per omission in the high probability state may trigger the transition to the low probability state. Therefore, the player recognizes that the downgrade crisis from the high probability state to the low probability state is present when the downgrade crisis effect screen 142 is displayed. The effect image display means 138 may execute the demote crisis effect as, for example, a screen having a dark background of a cold color.

  In this way, in order to arouse the player's interest in promotion or demotion by executing a promotion expectation effect or a relegation crisis effect, instead of notifying the player immediately of the game state upon occurrence of omission The time zone is provided. In the following, when the promotion expectation effect and the demotion crisis effect are collectively referred to as “elevation promotion effect”.

FIG. 7 is a time chart for explaining the relationship between generation per omission and promotion expected effects. In any of FIG. 7A to FIG. 7F, it is assumed that the state is in a low probability state before time t ₀ . To be precise, the special symbol lottery results are omitted, the special symbols are variably displayed, the special symbol lottery results are stopped and displayed, and after the second special game is executed for a short period of time, the promotion expected effect is started. Will be. Here, in order to simplify the explanation, the explanation will be made on the assumption that the timing at which the omission is generated coincides with the timing at which the second special game ends. If a normal hit occurs during the promotion expected effect, the omitted expected effect ends at the timing of the transition to the first special game.

FIG. 7A is a time chart when a non-probability change omission occurs in a low probability state.
In the figure, the non-probability variation omitted per occurs at time t _0, the promotion expected effect is started. In fact, the time t ₀ and later also remains a low probability state. However, as long as the player looks at the promotion expectation effect screen 140, the player cannot recognize whether the state remains in the low probability state or has shifted to the high probability state. Promotion expected to produce at the time t _1, which is a variation shortened game to end in 20 doses of the variable display after the special symbol of the time t ₀ is completed to the end. At time t ₁ after it is low probability state is indicated by the effect image, the player recognizes that Shisokona' promoted from a low probability state.
Internally, from time t ₀ to time t _1, there is a short time low probability state, and after time t ₁ is a normal low probability state.

FIG. 7B is a time chart when probability variation omission occurs in a low probability state.
In the figure, probability variation omitted per occurs at time t _0, the promotion expected effect is started. In this case, it is a high probability state actually from the time t _0. However, as long as the player looks at the promotion expectation effect screen 140, the player cannot recognize whether the state remains in the low probability state or has shifted to the high probability state. The case of FIG. 7 (b), after a time t _0, also promoted expected to produce finished fluctuations shorten the game and completed 20 times of the variable display of special symbols continues. That is, after the start of the promotion expectation effect, if the promotion expectation effect continues even after the special symbol variation display for 20 times is completed, the player deepens the conviction about the transition to the high probability state.
Internally, the time short high probability state is entered from time t _0, and when the fluctuation shortening game is completed, the normal high probability state is entered.

FIG. 7C to FIG. 7F are time charts when a further omission occurs during the promotion expected effect.
FIG. 7C is a time chart when probability variation omission occurs during the promotion expected effect due to non-probability variation omission.
In the figure, the non-probability variation omitted per occurs at time t _0, the promotion expected effect is started. In fact, the time t ₀ and later also remains a low probability state. Special before 20 times of the variable display of symbols is completed to vary shortened game is finished, i.e., probability variation omitted per occurs at time t ₂ in elevation expected effect. A high probability state from the time t _2. Time t ₀ or later, even if the variable display of 20 doses of the special symbol is completed, promoted expected production is continued. Therefore, it is easy for the player to be sure of the transition to the high probability state. In fact the time t ₂ and later in the figure, has been shifted to the high-probability state.
Internally, the time t ₀ from to time t ₂ is time-shortening low probability state, made from time t ₂ and the time-shortening high probability state, the variation shortened game ends with the probability variation per omission of time t _2, the normal high probability state Transition.

FIG. 7D is a time chart in the case where further non-probability change omission occurs during the promotion expected effect due to non-probability change omission.
In the figure, the non-probability variation omitted per occurs at time t _0, the promotion expected effect is started. Time t ₀ and later also remains a low probability state. Non-probability variation omitted hit is re-occur in the promotion expected performance during the time t ₃ of. Time t ₀ or later, even if the variable display of 20 doses of the special symbol is completed, promoted expected production is continued. Therefore, the player easily convinced the transition to high-probability state, but in the figure is also low probability state actually the time t ₃ or later. Promotion expected to produce at the time t ₄ to change shortened game due to hit the omission of the time t ₃ is finished is finished.
Internally, from time t ₀ to time t ₄ , a time-short low probability state is obtained, and after time t _4, a normal low probability state is obtained.

FIG. 7E is a time chart when a non-probable change omission occurs during a promotion expected effect due to a probable change omission.
In the figure, probability variation omitted per occurs at time t _0, the promotion expected effect is started. It is a high probability state from time t _0. Promotion expected non-probability variation omitted per at time t ₅ in production occurs, the time t ₅ and later re-enters the low probability state. Promoted expected production in time t ₆ to change shortened game is terminated due to non-probability variation omitted per the time t ₅ is completed.
Internally, the time-to-time high probability state is from time t ₀ to time t ₅ , the time-to-low probability state is from time t ₅ to time t _6, and the normal low-probability state is from time t ₆ onward.

FIG. 7F is a time chart in the case where further probability variation omission occurs during the promotion expectation effect due to probability variation omission.
In the figure, probability variation omitted per occurs at time t _0, the promotion expected effect is started. It is a high probability state from time t _0. Promoted expected again occurred per probability variation omitted at time t ₇ in the presentation, even time t ₇ after a high probability state is continued.
Internally, after the time t ₀ , until the fluctuation shortening game associated with the omission of the probability change at the time t ₇ is completed, the state is in a high-short-time probability state, and thereafter the normal high-probability state.

As described above, when the promotion expectation effect is started, the player is urged to expect the transition from the low probability state to the high probability state. As described with reference to FIGS. 7A and 7B, the player indirectly recognizes whether or not the probability change is possible depending on whether or not the promotion expected effect is continued for a long time. When the special symbol is displayed in a variable manner 20 times from time t ₀ , that fact may be clearly indicated to the player.
In addition, as described in relation to FIG. 7C to FIG. 7F, when the omission per unit occurs again during the promotion expectation effect, the end timing of the promotion expectation effect changes accordingly. It is possible to give fluctuations to the relationship between the end timing of the event and the success or failure of promotion. In the case of FIG. 7 (e), since the original low-probability state is returned to the high-probability state once, the opportunity cannot be utilized while shifting to the advantageous high-probability state. As long as the player sees the promotion expected performance, it is difficult to recognize such a change in the internal game state. As a result, the player can continue in the promotion expected to produce a sense of expectation for promotion from the time t ₀ to the high-probability state until time t _6. Further, in the case of FIG. 7 (f), the probability variation omission has reoccurred after the transition to the high probability state. Usually, in such a case, the player is likely to feel uncomfortable feeling that he / she has used wasteful luck due to the occurrence of the probability change omission even though the probability is already high. According to the production method in the present embodiment, even in such a case, since the reoccurrence per probability change omission in the promotion expected production is not clearly shown on the screen, the player's discomfort can be suppressed.

FIG. 8 is a time chart for explaining the relationship between generation per omission and demote crisis production. In any of FIGS. 8 (a) to FIG. 8 (f) also, and at time t ₀ before in a high probability state. To be exact, the special symbol lottery results are omitted, the special symbols are variably displayed, the special symbol lottery results are stopped and displayed, and after the second special game for a short period of time is executed, the demote crisis production is started. Will be. Here, for the sake of simplicity, the description will be made on the assumption that the timing at which the omission occurs and the timing at which the second special game ends coincide. If a normal win occurs during the relegation crisis production, the relegation crisis production ends at the timing of the transition to the first special game.

FIG. 8A is a time chart in the case where an uncertain change omission occurs in a high probability state.
In the figure, the non-probability variation omitted per occurs at time t _0, relegation crisis effect is started. From the time t ₀ a low probability state. However, as long as the player looks at the demoted crisis effect screen 142, the player cannot recognize whether the demoted state is demoted to a low probability state or whether the high probability state is maintained. After time t ₀ , the demotion crisis effect ends at time t ₁ when the variation display for 20 special symbols is completed and the variation shortening game ends. At time t ₁ after it is low probability state is indicated by the effect image, the player recognizes that demoted from a high probability state to a low probability state.
Internally, from time t ₀ to time t ₁ is the time-shortening the low-probability state, after time t ₁ is usually low probability state.

FIG. 8B is a time chart when probability variation omission occurs in a high probability state.
In the figure, probability variation omitted hit occurs at time t _0, demoted crisis production has been started. Time t ₀ and later also a high probability state is maintained. However, as long as the player looks at the demoted crisis effect screen 142, the player cannot recognize whether the demoted state is demoted to a low probability state or whether the high probability state is maintained. After time t ₀ , the demographic crisis effect ends at time t ₁ when the variation display for 20 special symbols is completed and the variation shortening game ends. At time t ₁ after it is high probability state is indicated by the effect image, the player recognizes that the high-probability state is maintained.
Internally, from time t ₀ to time t ₁ is the time-shortening high probability state, after time t ₁ is the normal high probability state.

FIG. 8C to FIG. 8F are time charts when a further omission occurs during the downgrade crisis presentation.
FIG. 8C is a time chart when a probability change omission occurs during a demotion crisis presentation due to a non-probability omission.
In the figure, the non-probability variation omitted per occurs at time t _0, demoted crisis effect starts, hits probability variation omitted time t ₂ in effect relegation crisis has occurred. Therefore, even if led to the end of the scheduled timing of the start has been change shortened game in time t _0, demoted crisis production is continued. After time t ₀ , even if the special symbol variation display for 20 times is completed, since the demoted crisis effect continues, the player's interest in whether or not the high probability state is maintained is further extended. Fluctuation shortened game triggered by the probability variation per omission of the time t ₂ is terminated at time t _3, also ends the relegation crisis director this time.
Internally, the time-to-time low probability state is from time t ₀ to time t ₂ , the time-to-high probability state is from time t ₂ to time t _3, and the normal high-probability state is from time t ₃ onward.

FIG. 8D is a time chart in the case where further non-probability change omission occurs during the promotion expected effect due to non-probability change omission.
In the figure, the non-probability variation omitted per occurs at time t _0, further non probability variation omitted per at time t ₄ in effect relegation crisis has occurred. In this case, also reached the timing to change shortened game is finished, which began in time t _0, demoted crisis production will be continued. In addition, fluctuations shortened game triggered by the per omission of the time t ₄ is terminated at time t _5, also ends the relegation crisis director this time.
Internally, from time t ₀ to time t _5, there is a short time low probability state, and after time t ₅ a normal low probability state.

FIG. 8E is a time chart in the case where a non-probable change omission occurs during a demotion crisis presentation by a probable change omission.
In the figure, probability variation omitted per occurs at time t _0, a non-probability variation omitted per at time t ₆ in effect relegation crisis has occurred. In this case, it demoted crisis director at the time t ₇ to change shortened game due to a non-probability variation omitted per the time t ₆ is finished is finished.
Internally, from time t ₀ to time t ₆ , a short time high probability state is obtained, from time t ₆ to time t ₇ is a short time low probability state, and from time t ₇ onward, a normal low probability state is obtained.

FIG. 8F is a time chart in the case where a further probability change omission occurs during a demotion crisis presentation due to a probability change omission.
In the figure, probability variation omitted per occurs at time t _0, more probability variation omitted per at time t ₈ in effect relegation crisis has occurred. Demoted crisis production in time t ₉ to change shorten the game is completed by the probability variation omitted per the time t ₈ is terminated.
Internally, from time t ₀ to time t _9, there is a short time high probability state, and after time t ₉ a normal high probability state.

As described above, when the demotion crisis effect is started, the player is aroused of anxiety about the demotion from the high probability state to the low probability state.
As described with reference to FIG. 8C to FIG. 8F, when the omission hit occurs again during the downgrade crisis production, the end timing of the downgrade crisis production is extended from the original end timing. For this reason, thrilling game nature can be exhibited by continuing a player's anxiety feeling further.

  Next, the operation process of the pachinko gaming machine 10 will be described using a flowchart. First, after describing a basic operation process, an effect control process in the sub-board 104 will be described.

FIG. 9 is a flowchart showing a basic operation process in the pachinko gaming machine.
The process shown in the figure is a process repeatedly executed as a loop process.
First, processing is performed when the game ball has won the start port 62, the general winning port 72, the big winning port 66, or when the game ball has passed through the operation port 68 (S10). (N in S12), a control process for a normal game such as a special symbol lottery is executed (S14). If a special game is in progress (Y in S12), a special game control process is executed (S16), and S10 to S16 The award ball payout according to the various winnings in the process up to is processed (S18).

FIG. 10 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). In accordance with the determination result, the main display control means 118 starts changing display and transmits a change start command to the effect display control means 134, and the decorative symbol display means 136 that receives the command starts changing display of the decorative symbol 190. (S36). Details of the success / failure determination process in S34 will be described later with reference to FIG. If the winning or failing lottery value is not held in S30 (N in S30), the processing from S32 to S36 is skipped, and if the symbol variation is being displayed in S32 (Y in S32), S34 and S36 Is skipped. Subsequently, if the symbol variation display has already started (Y in S38), the symbol variation display process is executed (S40). If the symbol variation display has not started (N in S38), S40 is skipped. . In S40, if the special symbol has been displayed with 20 variations after the variation shortening game ends, that is, after the start of the variation shortening game, the variation shortening game ends.

FIG. 11 is a flowchart showing in detail the success / failure determination process in S34 of FIG.
First, the success / failure lottery means 112 determines the success / failure value of the success / failure lottery value with reference to the success / failure determination table (S91). As described above, the range of the success / failure lottery value to be won depends on whether the state is a probability variation state or a non-probability variation state.

If it is normal hit (Y in S92), the variation shortening execution means 126 is set to start the variation shortening game after the end of the first special game (S98). The probability variation executing means 122 is set to be in a high probability state after the first special game is finished (S100). That is, the transition to the short time high probability state after the end of the first special game is reserved.
If it is per omission (N in S92, Y in S94), the probability variation execution means 122 determines whether it is per probability variation omission or non-probability variation omission (S96). If the probability change is omitted (Y in S96), the transition to the short time high probability state after the end of the second special game is reserved (S98, S100). On the other hand, if the non-probability change is omitted (N in S96), the transition to the short time low probability state after the end of the second special game is reserved (S102, S104).
If it is off (N in S92, N in S94), the probability of the special symbol lottery does not change, and the fluctuation shortening game is not executed.
The symbol determining means 114 acquires the pattern lottery value and determines the display pattern of the special symbol (S106). A stop symbol is set according to the result of the special symbol lottery.

FIG. 12 is a flowchart showing in detail the special game control process in S16 of FIG.
When the first special game is already being executed (Y in S110), the first special game control process is executed (S112). If the first special game is not being executed (N in S110), the second special game control process is executed (S114). Each process will be described with reference to FIGS. 13 and 14.

FIG. 13 is a flowchart showing in detail the first special game control process in S112 of FIG.
First, if the big prize opening 66 has not been opened (N in S70), the effect display control means 134 starts the special game effect processing (S72), and the open / close control means 124 opens the special prize opening 66 (S72). . 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 hole 66 has not reached nine or more (N in S78), the process from S80 is skipped and the flow in S112 is performed. Exit.

  If the number of rounds of the unit game has reached 15 after the closing of the special winning opening 66 in S80 (Y of S82), the effect display control means 134 ends the effect process of the first special game (S84), and the special game The control means 120 ends the first special game (S86). If the number of rounds has not reached 15 (N in S82), 1 is added to the number of rounds and the flow in S112 is terminated (S90).

FIG. 14 is a flowchart showing in detail the second special game control process in S114 of FIG.
First, if the big prize opening 66 has not been opened (N in S120), the opening / closing control means 124 opens the big prize opening 66 (S122). If the special winning opening 66 has been opened, S122 is skipped (Y in S120). When a predetermined opening time of 0.2 seconds elapses after the big prize opening 66 is opened (Y in S124), the big prize opening 66 is closed (S126). When the opening time has not elapsed (N in S124), the processing after S126 is skipped and the flow of S114 is terminated.

  If the number of rounds of the unit game has reached 2 after the closing of the special winning opening 66 in S126 (Y in S128), the second special game is ended (S130). If the number of rounds has not reached 2 (N in S128), 1 is added to the number of rounds, and the flow of S114 is terminated (S132). In this way, the second special game is a special game that is executed only for an extremely short time of about 0.2 seconds, which is 0.2 × 2 compared to the first special game. Therefore, the special game effect as in the first special game is not executed.

  As a modified example, the special game control unit 120 may suppress various accessory actions when the game is shifted to the second special game. For example, the special game control means 120 may suppress the opening / closing operation of the special winning opening 66 of S122 or S126 and the blinking operation of the game effect lamp 90. The special game control means 120 may internally manage about 0.4 seconds as the second special game state, and automatically return from the second special game to the normal game when 0.4 seconds have elapsed. In this case, since the opening / closing operation of the special winning opening 66 and the blinking operation of the game effect lamp 90 are not executed, the player does not even recognize that the player is in the second special game state from the accessory operation. Since the profit as the second special game cannot be expected and cannot be recognized, the omission per unit can be clarified as a pure “probability change opportunity” and “short-time opportunity”. Since the difference between the normal hit and the omitted hit can be clarified, it is possible to provide a game that is easier for the player to understand.

  Further, as a modified example, the special game control means 120 executes a normal special game as shown as the first special game in the present embodiment when a normal win occurs, but when a default win occurs, the special game control means 120 plays a special game. The state may not be changed. In this case, the process itself of S114 is not executed. Even in such an aspect, the difference between the two types can be further clarified, which is effective in providing a game that is easier to understand for the player.

FIG. 15 is a flowchart showing an effect display control process in the sub-board.
The flowchart shown here shows the process performed mainly by the effect determining means 132 and the effect image display means 138 of the sub-board 104. In the present embodiment, the effect display control on the sub-board 104 is executed as a separate process although linked with the main flow on the main board 102. The process shown in the figure is repeatedly executed as a loop process.

  First, if the symbol is already fluctuating (Y in S140), the decorative symbol display means 136 determines whether it is time to end the fluctuating display (S142). If it is the fluctuation stop timing (Y of S142), the decorative symbol fluctuation display is stopped (S144). If it is the end timing of the up-and-down grade effect (N of S146), the effect image display means 138 ends the up-and-down grade effect being executed (S148). Next, a winning effect process relating to the winning effect is executed (S150). The winning effect process will be described in detail with reference to FIG. If the change end timing has not been reached (N in S142), the change display is continued as it is (S162).

If it is the decorative symbol variation start timing (N in S140, Y in S152), the effect determining means 132 selects the display pattern of the decorative symbol (S154). The decorative symbol display means 136 starts the variable display of the decorative symbol with the selected display pattern (S156).
If it is the timing when the first special game ends (N in S140, N in S152, Y in S158), the effect image display means 138 ends the special game effect for the first special game (S160).

FIG. 16 is a flowchart showing in detail the winning effect process in S150 of FIG.
If it is a normal hit (Y in S170), the effect image display means 138 starts a special game effect (S172). If it is per omission in the low probability state (N in S170, Y in S174, Y in S176), the effect image display means 138 starts the promotion expected effect (S178). If it is per omission in the high probability state (N in S170, Y in S174, N in S176), the effect image display means 138 starts the demote crisis effect (S180). On the other hand, if it is off (N in S170, N in S174), the winning effect process in S150 ends.

As described above, according to the pachinko gaming machine 10 shown in this embodiment, the promotion expected effect or the demoted expectation effect is executed in response to the occurrence per omission. In the low probability state, the player's expectation for promotion to the high probability state is evoked by the promotion expectation effect. In the high probability state, the player's anxiety about the relegation to the low probability state is aroused by the relegation crisis production. Therefore, it is possible to further enhance the player's immersive feeling with respect to the game by the production according to the situation at the time of occurrence of omission.
As shown in FIG. 1, while the gaming machine has various internal gaming states, the promotion expectation effect and the relegation crisis effect have the effect of obscuring part of such changes, Can provide games in a simpler way than it actually is.

  In the above, this invention was demonstrated based on the Example.
