Description

  The present invention relates to a ball game machine such as a pachinko game machine, and more particularly to a technique for controlling screen display contents in a ball game machine.

  Conventionally, among the various ball game machines, a so-called first type pachinko game machine is used while changing a plurality of symbols in a display area such as a liquid crystal display provided substantially at the center of the game board. Display (hereinafter, such display is referred to as “symbol change” or “change display”). This gaming machine shifts to a special game called so-called jackpot where more prize balls can be obtained than a normal game when a combination of symbols when a plurality of rows of symbol variations are stopped becomes a specific mode. It is known as a thing (for example, refer patent document 1). The variable display of symbols in the display area is not only a variable display of multiple symbols, but the time of variable display is usually reduced in a state where it is a big hit if one more symbols are aligned, as in the so-called reach screen. For example, an effect is made to increase the player's expectation, such as making it longer. In addition, the player's expectation can be enhanced by controlling the specific game such as the probability variation that changes the probability of transition to special games by giving the story to the variation display using characters on the images such as symbols Yes.

  As game contents and production contents diversify, the time that can be allocated to various lottery processes in a large amount of arithmetic processing inside the gaming machine is generally short. Although the processing time depends on the clock frequency of the central processing unit (CPU), for example, when the timer interruption period is set to 4 milliseconds, the determination process of the pass / fail lottery process or the symbol variation time is about 3.5 milliseconds. To spend. As a lottery value generation method, a method using a pseudo-random number such as a software random number is known, but a process such as a software random number counter update is a basic process such as the above-mentioned lottery process or the determination process of the symbol variation time. It is common to use the remaining time. For example, if 3.5 seconds are spent in the core process, the software random number counter update process leaves less than 0.5 milliseconds. If the remaining time is longer, it becomes possible to further increase the irregularity of the software random number, and there are great security advantages such as countermeasures against illegal operations. However, the room that can be reduced due to the core processing is inherently small and difficult to reduce. On the other hand, because it is difficult to reduce, there is also an aspect in which game content is likely to be stiffened and monotonous unless it is innovative in terms of production.

  The present invention has been made in view of these problems, and an object of the present invention is to improve security and avoid monotonousness of the game by improving the efficiency of the control of the screen display content in a ball game machine.

  In order to solve the above-described problems, a ball game machine according to an aspect of the present invention is provided with a game board on which a game area is formed, and a predetermined position in the game area. A winning lottery means for executing a winning lottery for determining whether or not to shift to a special game that is more advantageous to the player than a normal game, triggered by entering the starting prize port, A symbol display device for variably displaying symbols for indicating the result of the winning / failing lottery, and a variation for executing a fluctuating lottery for determining whether or not the symbol variation display is omitted for the entrance into the start winning opening. Controls the variation display of symbols on the lottery means and the symbol display device, and starts the variation display of symbols according to whether or not the variation display of symbols determined according to the lottery result of at least one of the winning lottery and the variation lottery can be executed. Display control means When the propriety lottery results are displayed in a manner that indicates the hit is symbol becomes a win, provided with special game control means for executing a special game, a.

  Here, “variation display is omitted” may be a form in which the symbol variation itself is not executed, or in an inconspicuous form that is almost unrecognizable by the player, for example, by replacing it with a very short symbol variation. It may be of any shape. “Win / Draw lottery” and “Variation lottery” do not necessarily determine whether or not the symbol variation can be executed unless both are executed, and sometimes it is determined by executing both or when only one is executed. There may be. That is, whether or not execution is determined at the time when one of the lotteries is executed first may be determined, or may be determined only when another lottery is executed. The bullet ball game machine may further include a variation pattern determining means for selecting one of a plurality of variation patterns in which the variation process from the start to the stop of the symbol variation is determined according to the result of the lottery determination. The variation pattern determination means may omit the variation pattern selection process when it is determined that the symbol variation display is omitted by at least one of the winning / failing lottery and the variation lottery.

  According to this aspect, it is possible to improve the efficiency of the game progress by omitting a part of the symbol variation instead of completely executing the symbol variation for all the balls entering the start winning opening. . In addition, when the symbol variation is omitted, the symbol variation pattern determination process can be simplified, and resources can be allocated to a more important process by improving the efficiency of the control. In particular, resources can be used to improve the security of gaming machines.

  The fluctuating lottery means may execute the fluctuating lottery only when the result of the lottery determination is not good. In this case, it is possible to improve the efficiency of control by executing the lottery lottery first and executing the symbol variation whenever the lottery is successful, and omitting the symbol variation at least partially when it is out of place. it can. In addition, when the winning / failing lottery is a win, it is assumed that the symbol variation is always executed, and conversely, if the symbol variation is started, it can be expected that the player will win / fail the winning lottery. In this way, not only the efficiency of the game can be improved, but also a game property that increases the player's expectation can be realized. However, as another aspect, it is good also as a structure which performs a variable lottery, even when a win / fail lottery is a win.

  The success / failure lottery means may execute the determination of success / failure by the success / failure lottery only when the result of the variable lottery corresponds to the result that the change display of the symbol is not omitted. In this case, the fluctuating lottery is executed first, and only when the decision to execute the symbol fluctuation is made as usual, the winning / failing lottery is executed. Thereby, when symbol variation is omitted, it is possible to avoid the success / failure lottery process, simplify the process, and allocate resources to more important processes. In particular, resources can be used to improve the security of gaming machines.

  As a prize opening provided at a predetermined position in the game area, a large winning opening that is opened so that a player can enter a ball in a special game, and a result that the variable lottery result by the variable lottery means omits the symbol variation display. In this case, an open / close control means for opening the special winning opening for a predetermined time may be further provided instead of omitting the symbol display. In this case, even when the symbol variation is omitted, the player can be given a profit for entering the starting winning opening. In general, the so-called first type pachinko gaming machine of the prior art is a game that grants a jackpot through winning / notting lottery and symbol variation for a ball entering a start winning opening. In addition, the so-called second type pachinko game is a game in which a big winning opening is opened for entering a starting winning opening, and a jackpot is awarded according to the entering into the large winning opening. The above aspect is an eclectic configuration in which the benefit of either the first type or the second type is provided to the player. In this way, the symbol variation can be omitted without decreasing the profit of the player by opening the special winning opening when the symbol variation is omitted.

  The success / failure lottery means may integrate the number of times the symbol is displayed in a variation, and may also add the number of times the symbol is displayed in the variation lottery result even if the result of the variation lottery is omitted. For example, the number of times the symbols are changed may be output to a management device or an external display device installed on the pachinko hall side, and the number of changes may be displayed on the external display device according to the output information. The number of fluctuations displayed in this way is a guideline for the number of balls entering the start winning opening per unit time for the player, and it is customary to determine whether the base is good or bad based on the number of fluctuations. Therefore, if the number of times is not added each time the symbol variation is omitted, the standard for judging whether the stand is good or bad becomes unclear for the player. According to this aspect, since the player can confirm the number of balls entered into the start winning opening regardless of whether or not the symbol variation is omitted, it is possible to avoid the disadvantage caused by the symbol variation omitted.

  If the result of the winning / failing lottery corresponds to a specific type of hit, in a normal game after the end of the special game executed in response to that hit, a predetermined game state that is more advantageous to the player than the normal state is predetermined. The specific game executing means and the variable lottery means for shifting over the period may execute the variable lottery in a predetermined period in the specific game state. Here, the “specific game state” may refer to, for example, a probability variation state in which the probability of winning in the lottery is higher than in the normal state, or refers to a game state in which the symbol variation time is shorter than in the normal state. Also good. Since the specific game aims to increase the easiness of appearance of the next jackpot, it is preferable that the next win appears as early as possible. In this respect, in this aspect, the symbol variation using the variation lottery is omitted in the period of the specific gaming state, and the symbol variation is made efficient.

  If a symbol change corresponding to the previous lottery is displayed when a new lottery is executed as a winning / failing lottery, the new lottery result is displayed up to the predetermined number up to the start of the symbol change display corresponding to that lottery. You may further provide the holding control means to hold. The holding control means may further hold the lottery result when the variable lottery is made until the symbol variable display corresponding to the lottery is started or omitted. In this case, at least one of the winning / losing lottery and the variable lottery can be executed at the timing of entering the start winning opening, and the lottery result can be put on hold. Thereby, it is possible to further improve the processing efficiency by determining in advance before the symbol variation start timing arrives.

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

  According to the ball game machine of the present invention, it is to improve the security and avoid the monotonousness of the game by increasing the efficiency of the control of the screen display content.

  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 that it can be opened and closed 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 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. Furthermore, 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 expansion mechanism of the start port 62 is expanded, the opening width of the start port 62 is expanded and the ease of entering the ball is improved. 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 “big hit” 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 winning detection device 78 of the big winning opening 66 includes a sensor that detects the passage of a game ball.

  The special symbol display device 61 provided on the left side of the game area 52 and the effect display device 60 provided in the approximate center of the game area 52 have a variation of the special symbol 192 on each screen and a decoration 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”). Here, the special symbol 192 is a symbol corresponding to the result of the lottery performed when the game ball is dropped into the start port 62, and the symbol mode when the change display is stopped is determined to be the winning symbol. When the symbol is a symbol, the timing at which the stop symbol is displayed is the jackpot occurrence timing. The special symbol display device 61 is display means composed of, for example, 7 segment LEDs. The effect display device 60 is a liquid crystal display that variably displays the decorative symbol 190 in a manner interlocked with the variation display of the special symbol 192. The decorative symbol 190 is a symbol for visually rendering the lottery result display indicated by the special symbol 192. The effect display device 60 displays, as the decorative symbol 190, for example, a plurality of rows of moving images of symbol variation simulating a slot machine game in the central area of the screen. The effect display device 60 is constituted by a liquid crystal display in this embodiment, but may be constituted by a mechanical rotating device such as a drum or other display means such as an 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 a decorative role is not displayed and a decorative symbol is not displayed, the special symbol may be displayed on a liquid crystal display such as the effect display device 60. 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 passage of the game ball to the operation port 68 triggers an open lottery for determining whether or not to expand the expansion mechanism of the start port 62. When the game ball passes through the operation port 68, a normal symbol, which is a symbol indicating the result of the open lottery, is variably displayed on the normal symbol display device 59. The normal symbol display device 59 is provided on the lower right side of the effect display device 60. 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%.

  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. A lottery hold lamp 20 is provided below 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. . 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. 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. Furthermore, game effect lamps 90 are respectively provided above and below the effect display device 60. The operation button 82 is a button operated by 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.

  When the player rotates 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 rotation 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”.

  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 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 decorative pattern 190 simulating the game of the slot machine takes a display mode in which the three patterns 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. Such opening / closing of the big prize opening 66 is repeated a predetermined number of times, for example, 15 times. In the present embodiment, the grand prize winning opening 66 is opened for a short time even at a timing other than the special game. The opening timing of the special winning opening 66 other than the special game will be described later.

  In the normal game after the end of the special game, a variable time shortening game (hereinafter referred to as “time reduction” as appropriate) that is one of the specific games is started. In the variation time shortening game, the variation time of the special symbol and the decorative symbol is shortened from the normal time. The variation time of the special symbol and the decorative symbol is returned to the original variation time after the variation display of a predetermined variation number is performed. As a modification, when a special game occurs and the winning stop symbol at that time is in a specific mode, a probability variation game (hereinafter referred to as “ The configuration may be such that “probability” is further started. In the probability variation game, a lottery with a higher win probability than the normal probability state is performed, and a new special game is generated relatively early.

  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 power of 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 substrate 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.

  In the present embodiment, the main board 102 includes a ball determination unit 110, a winning / failing lottery unit 112, a variation lottery unit 113, a symbol determination unit 114, a variation pattern determination unit 115, a hold control unit 116, a main display control unit 118, and a special game control. Means 120, specific game execution means 122, and opening / closing control means 124 are provided. The sub-board 104 in the present embodiment includes a pattern storage unit 130, a design mode determination unit 131, an effect determination 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 success / failure lottery means 112 accepts a random number value to determine whether or not to shift to a special game that is more advantageous to the player than the normal game when the game ball enters the start port 62. Get as a value. For example, the success / failure lottery value is acquired from a value range from “0” to “999”. The “random number” referred to in the present application may not be a mathematically generated random number, and is assumed to be a pseudo-random number generated by a software random number, but may be a pseudo-random number generated by a hardware random number as a modified example. . These pseudo-random numbers are values obtained by extracting counter values updated at a predetermined cycle at random timing. This update process of the counter value is executed in the remaining period excluding the basic process such as the determination process of the success / failure determination and the determination process of the symbol variation time in the unit processing time divided by the timer interruption period. The length is generally short.

  The success / failure lottery means 112 holds a success / failure table referred to in the determination of success / failure. In the success / failure table, a determination result of winning or losing is associated with a success / failure lottery value, and the success / failure probability is determined according to the associated winning range setting. The success / failure lottery means 112 refers to the success / failure table to determine whether or not the success / failure lottery value is a win. The determination result by the success / failure lottery means 112 is variably displayed in a special symbol form on the special symbol display device 61. In addition, a decorative symbol 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 fluctuation lottery means 113 executes a fluctuation lottery for determining whether or not the symbol fluctuation display is omitted for the ball entering the start port 62. The fluctuating lottery value is a random number similar to the winning / failing lottery value, and is acquired from a value range from “0” to “999”, for example. The variable lottery means 113 holds a variable lottery table that is referred to in the variable lottery. In the variation lottery table, the result of omitting the symbol variation display or the result of not omitting the symbol and the variation lottery value are associated with each other, and the probability of variation omission is determined according to the associated range setting. The fluctuation lottery means 113 refers to the fluctuation lottery table and determines whether or not the symbol fluctuation display is omitted. In the present embodiment, the variable lottery means 113 executes the variable lottery only when the result of the lottery determination is unacceptable. That is, when the winning lottery is won, the symbol variation display is always performed, and when the winning lottery is lost, the symbol variation display can be omitted. In the present embodiment, the variation lottery table is designed so that the symbol variation display is omitted with a probability of 99/100 out of the cases where the winning lottery is missed.

  The symbol determination means 114 determines the stop symbol of the special symbol to be displayed on the special symbol display device 61 according to the lottery result by the success / failure lottery means 112. However, when the change lottery means 113 determines that the symbol change is omitted, the symbol determination means 114 omits the symbol determination process. Moreover, the symbol determination means 114 determines the stop symbol of the normal symbol displayed on the normal symbol display device 59 by lottery. The stop symbol is a symbol to be displayed at the end of symbol variation. The symbol determination means 114 holds a symbol range table to be referred to in order to determine a special symbol or a normal symbol stop symbol.

  The symbol determination means 114 acquires a symbol determination lottery value for determining a special symbol, and determines the stop symbol of the special symbol according to the determination result of the success / failure lottery means 112 and the symbol determination lottery value. The symbol determination unit 114 sends data indicating the determined stop symbol to the main display control unit 118, the symbol mode determination unit 131, and the effect determination unit 132.

  The symbol determining means 114 acquires a lottery random number for determining a normal symbol when the game ball passes through the operation port 68, 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 variation pattern determination means 115 selects any variation pattern from a plurality of types of variation patterns according to the result of the success / failure lottery. However, when the variation lottery means 113 determines that the symbol variation is to be omitted, the variation pattern determination unit 115 omits the variation pattern selection process. The variation pattern determining means 115 holds a pattern selection table to be referred to in order to determine the variation pattern. The symbol determination unit 114 sends data indicating the determined variation pattern to the main display control unit 118, the symbol mode determination unit 131, and the effect determination unit 132. The variation pattern determination means 115 stores a plurality of types of variation patterns in which variation modes from the variation start to the stop when the special symbol is variably displayed are defined. A plurality of types of variation patterns are defined on the assumption that there are various variation times, short and long, and that symbol variation is also performed by a decorative symbol composed of a plurality of symbols in the variation time. In each variation pattern, a variation display time is defined for each pattern as an end condition of the symbol variation, and the variation of the special symbol and the decorative symbol is stopped when the variation display time elapses.

  The hold control means 116 holds the winning / losing lottery value acquired by the winning / failing lottery means 112 as a holding ball. In other words, when a new lottery is executed as a success / failure lottery and the symbol variation corresponding to the previous lottery is displayed, the hold control unit 116 responds to the lottery with the result of the new lottery up to a predetermined number. Hold until the start of the variable display of the symbol to be displayed. The upper limit of the number of holds is 4. The holding control means 116 further holds the lottery result when the variable lottery is made until the symbol variable display corresponding to the lottery starts or is omitted.

  The main display control means 118 causes the special symbol display device 61 to display the lottery result by the success / failure lottery means 112 as a special symbol fluctuation display according to the fluctuation pattern determined by the fluctuation pattern determination means 115. The main display control means 118 starts the symbol display according to whether or not the symbol variation determined according to the lottery result of the success / failure lottery and the variation lottery can be omitted. Therefore, when the symbol variation is determined to be omitted, the symbol variation is determined. Do not start. 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, so that the main display control means 118 and the effect display are displayed. The fluctuation display by the control means 134 is synchronized and interlocked. 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 result of the success / failure lottery by the success / failure lottery means 112 is a win and the symbol is displayed in a manner indicating a win. The special game is a game in which the opening / closing operation of the special winning opening 66 is continuously performed a plurality of times, and is configured by 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 in this embodiment is a short time when the symbol variation time is switched from a normal time to a short time.

  The specific game execution means 122 shifts the game state to the short-time state after the special game, regardless of the winning / failing lottery value. The short time is continued until the number of changes in the special symbol after the special game reaches a predetermined number, for example, 100 times. As a modification, the specific game executing means 122 may shift the game state after the special game to the probability change state when the winning / losing lottery value is a value to be shifted to the probability change state. The probability variation state is continued until the next jackpot is generated in principle, and during that time, the probability of the hit determination by the success / failure lottery means 112 is maintained at a high value.

  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. When the result of the fluctuation lottery by the fluctuation lottery means 113 corresponds to the result that the change display of the symbol is omitted, the opening / closing control unit 124 sets the special winning opening 66 for a predetermined short time instead of omitting the display of the change of the symbol. For example, it is opened only for about 1 second. This release is not a special game release, but if you enter during that time, you can get a prize ball, so it can be meaningful for the player to compensate for the omission of symbol variation, and also to ensure the player's profit Become.

  The pattern storage means 130 holds a plurality of effect patterns in which effect image contents to be displayed on the effect display device 60 in the variation of the decorative design 190 and the display process thereof are determined. The effect pattern is displayed separately from a plurality of variation effect patterns in which the variation process from the variation start to the stop in the variation display of the decoration symbol 190 and the effect process are defined, and the variation display of the decoration symbol, and the degree of expectation to the jackpot And a plurality of notice effect patterns suggesting the height of the notice.

  The effect determining unit 132 determines the variation effect pattern according to the result of the lottery performed by the success / failure lottery unit 112, the stop symbol of the special symbol, and the variation pattern of the special symbol. The effect determining unit 132 holds a pattern table to be referred to in order to determine the variable effect pattern. The effect determining means 132 sends information on the determined variation effect pattern to the effect display control means 134. However, when the change lottery means 113 determines that the symbol change is omitted, the effect determination means 132 omits the change effect pattern determination process.

  The variation production pattern includes a pattern for displaying a normal out-of-order symbol combination, a pattern for displaying an out-of-order symbol combination after reaching a big win if one more symbols are aligned, and a reach state. A pattern for displaying a jackpot symbol combination is included. In particular, the pattern that passes through the reach state includes patterns having various fluctuation times. Each variation effect 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 determining unit 132 selects a variation effect pattern of the effect image having the same variation time according to the variation pattern of the special symbol.

  The symbol form determining means 131 determines the combination and arrangement of the stop symbols of the decorative symbols in accordance with the result of the lottery by the pass / fail lottery means 112, the special symbol stop symbol, the special symbol variation pattern, and the decorative symbol variation effect pattern. To do. However, when the change lottery means 113 determines that the symbol change is to be omitted, the symbol form determination means 131 omits the decorative symbol determination process. The symbol form determination unit 131 transmits information indicating the determined combination of stop symbols to the effect display control unit 134. The symbol form determining means 131 holds a symbol range table to be referred to in order to determine the stop symbol of the decorative symbol.

  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 a shift to a special game, three symbols such as “777” and “111” are arranged. A combination is selected. In this case, it is preferable that the same numbers as the special symbols are selected as the numbers to be arranged as the decorative symbols. For example, when the special symbol is “3”, the decorative symbol is “333”. In the case where the determination result by the success / failure lottery means 112 indicates that the game does not shift to the 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 special game, and the variation pattern of the special symbol indicating the detachment with reach or the variation effect pattern of the decorative symbol is selected, “191” or “727” is selected. "A combination that does not have only one symbol, such as"

  The notice effect pattern is an effect pattern for temporarily displaying an image, animation, video, or the like of a specific character or motif, or an effect pattern for outputting a specific sound. The effect by the notice effect pattern is executed in parallel with the symbol variation, and suggests in advance that the symbol variation is highly expected to stop in the big hit mode. For example, there are a normal notice effect in which only one character image is displayed on the screen, and a group notice effect in which a large number of characters are displayed so as to pass from one end to the other end of the screen. Further, the display process of the notice effect is divided into a plurality of stages, and the number of stages to be displayed is variable, and a step-up notice effect that is set such that the higher the number of stages is, the higher the expectation for the big hit is included.

  The notice effect pattern includes a pattern in which the effect is executed at a timing after the display form of the decorative symbol 190 reaches the reach state and the final stop state of the symbol is notified, and no decorative symbol 190 is stopped. There is a pattern in which the performance is executed at the timing and the reach is reached at the same time.

  The effect determining means 132 determines whether or not to display the notice effect on the effect display device 60 according to the result of the lottery determination, and determines the notice effect pattern to be displayed. The effect determining means 132 holds a notice determination table that should be referred to in order to determine whether or not to display the notice effect, and a notice type table that should be referred to when selecting the type of the notice effect pattern. The notice decision table is set so that different columns are referred to depending on the result of the lottery, and if the lottery is a win, the notice lottery will be displayed with a higher probability than if it was missed. Correspondence between whether to display the result and the notice effect is determined. Thereby, the high expectation degree to the jackpot can be suggested by displaying the notice effect itself.

  The effect display control means 134 displays the effect image including the decorative pattern on the effect display device 60 according to the selected change effect pattern data as a result of the success / failure lottery by the success / failure lottery means 112. The effect display control means 134 starts the symbol display according to whether or not the symbol variation determined according to the lottery result of the success / failure lottery and the variation lottery can be omitted. When it is determined that the symbol variation is omitted, the decorative symbol is displayed. Variation display of effect images including is not started.

  The effect display control means 134 causes the effect display device 60 to display the notice effect according to the selected notice effect pattern when the effect determining means 132 determines to display the notice effect. 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.

  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.

  FIG. 4 is a diagram schematically showing the relationship between the determination result based on the success / failure lottery value and the variation lottery value and whether the variation can be omitted. In a present Example, it determines with 0-989 being out of the lottery value of 0-999, and it determines with 990-999 winning. Also, if the winning lottery is a win, the symbol variation will not be omitted even if the dynamic lottery is not passed. To do. In the present embodiment, among the fluctuation lottery values of 0 to 999, when 0 to 989, it is determined to omit the symbol variation, and when 990 to 999, it is determined not to omit the symbol variation. In this way, by executing the fluctuation lottery after executing the winning / failing lottery, the symbol variation is not always executed every time the ball enters the starting port 62, but the gameability that the symbol variation can be omitted is achieved. realizable. As a result, in the present embodiment, the success / failure lottery itself is a big hit with a probability of 1/100, but the symbol variation is omitted with a probability of 99/100 out of deviations, and the symbol variation is not omitted with 1/100 out of outages. It is only a probability. Including the winning case in the lottery, the symbol variation as a whole is omitted with a probability of about 98/100, and the symbol variation without omission is performed with a probability of about 2/100. As a result, it is possible to realize a game that will be a big hit with a probability of about half of the cases where symbol variation is executed without omission, and once the symbol variation starts, the game will have the expectation that it will be a big hit once every two games. Can be given to a person. Moreover, it is possible to prevent the game from becoming monotonous by limiting the opportunities for the symbol variation to be executed instead of the symbol variation being performed every time the starting port 62 is entered.

  FIG. 5 is a flowchart showing a basic operation process in the pachinko gaming machine. 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), control processing for normal games such as winning / failing lottery is executed (S14), and if a special game is in progress (Y in S12), control processing for special game is executed (S16), from S10 to S16 In step S18, a prize ball payout corresponding to various winnings is processed.

  FIG. 6 is a flowchart showing in detail the normal game control process of S14 in FIG. In the normal game control process, a pre-judgment process related to entering the starting port 62 is executed (S28), and the winning / failing lottery value is held (Y in S30), and the symbol variation must be displayed. If this is the case (N in S32), the success / failure lottery means 112 executes a success / failure determination process (S34). If it is determined that the symbol variation is not to be omitted by the variation lottery (Y in S35), the main display control means 118 starts the variation display according to the determination result, and the variation start command is effect-displayed. The effect display control means 134 transmitted to and received by the control means 134 starts the effect image change display according to the change pattern data (S36). On the other hand, when it is determined that the symbol variation is omitted by the variation lottery (N in S35), the opening / closing control means 124 opens the special winning opening 66 for about 1 second (S37). 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. .

  FIG. 7 is a flowchart showing in detail the advance determination process of S28 in FIG. When there is a ball in the starting port 62 (Y in S42), the winning / not-lotting means 112 acquires the winning / losing lottery value (S44), and when the winning / losing lottery value is out (Y in S45), the variable lottery means 113. Acquires the fluctuation lottery value (S46), determines whether or not the symbol fluctuation can be omitted based on the fluctuation lottery value (S48), and stores the result of lottery determination and the fluctuation lottery result in the hold control means 116 (S50). In S45, when the winning / failing lottery value is a win (N in S45), the processing of S46 and S48 is skipped, and the result of not omitting the winning / losing lottery result and the symbol variation is stored in the holding control means 116 ( S50). The success / failure lottery means 112 may determine whether or not it is successful based on the success / failure lottery value and then store the result in the hold control means 116 or may store the success / failure lottery value itself. The fluctuation lottery means 113 stores the determination result on whether or not the symbol fluctuation can be omitted based on the fluctuation lottery value in the hold control means 116, but as a modification, the variable lottery value itself may be stored. If there is no entry at the start port 62 in S42, the processing from S44 to S50 is skipped (N in S42).

  FIG. 8 is a flowchart showing in detail the success / failure determination process of S34 in FIG. First, the success / failure lottery means 112 reads the results of the success / failure lottery and the fluctuation lottery from the holding control means 116 (S52). If the result is that the symbol variation is not omitted (Y in S54), the success / failure lottery means 112 reads out the result. Whether or not the winning is determined based on the winning or failing lottery value (S56). The symbol determining means 114 determines a stop symbol of the special symbol based on the determination result (S58), and selects a variation pattern of the special symbol (S60). The CPU of the main board 102 processes all the processes of S52 to S60 within one timer interrupt period, and updates the counter values of random numbers of the winning lottery value and the variable lottery value during the remaining time (S62). The effect determination means 132 determines the stop symbol combination of the decorative symbols based on the determination result and the special symbol (S64), and selects the variation pattern of the decorative symbol according to the variation pattern of the special symbol (S65). If the result of variation lottery is that the symbol variation is omitted in S54 (N in S54), all the processing of S56 to S60 is skipped, and the random number counter value of the winning lottery value and the variable lottery value is calculated in the remaining time. Update (S66). As described above, when the determination of success / failure or symbol variation is omitted, the time required for the processing of S56 to S60 can be reduced, and the reduced time is allocated to the counter value update processing of the random number, and the random number updating method is further improved. It can also be complicated. If the update method can be made more complex and irregular, unauthorized operations by malicious players can be prevented more effectively. After S65 or S66, the success / failure lottery means 112 counts the number of symbol variations and outputs it to the external device on the pachinko hall side (S68).

  FIG. 9 is a flowchart showing in detail S16 in FIG. First, if the big prize 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 prize opening 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). If the number of rounds has not reached 15 (N in S82), 1 is added to the number of rounds and the flow of S16 is terminated (S90).

(Example 2)
The present embodiment is different from the first embodiment in which the variable lottery is executed only when the winning lottery is missed in that the variable lottery is executed even when the winning lottery is won. Since other configurations and operations are the same as those in the first embodiment, differences from the first embodiment will be mainly described, and description of the common points will be omitted.

  FIG. 10 is a diagram schematically illustrating the relationship between the success / failure determination result based on the success / failure lottery value and the variation lottery value and whether or not variation can be omitted. In a present Example, it determines with 0-979 being out of the lottery value of 0-999, and it determines with 980-999 winning. In addition, when the winning / losing lottery is out of the lottery value of 0 to 999, it is determined that the symbol variation is omitted when it is 0 to 989, and the symbol variation is not omitted when it is 990 to 999. On the other hand, when the winning / losing lottery is a win, among the fluctuation lottery values of 0 to 999, it is determined that the symbol variation is omitted when it is 0 to 499, and when it is 500 to 999, the symbol variation is not omitted.

  In this way, by executing the fluctuation lottery after executing the winning / losing lottery, the symbol variation is not always executed every time the ball enters the start port 62, and a gameability in which the symbol variation can be omitted is realized. it can. As a result, in the present embodiment, the success / failure lottery itself has a jackpot result with a probability of 2/100. However, since the symbol variation is omitted with a probability of 1/2 and no jackpot is generated, the actual winning probability is 1 / 100. In addition, even if the winning / failing lottery is missed with a probability of 98/100, the symbol variation is executed only with a probability of about 1/100, so when combined with the winning / raising lottery, the probability is only about 2/100. The symbol change without omission is not executed. As a result, it is possible to realize a game that will be a big hit with a probability of about half of the cases where symbol variation is executed without omission, and once the symbol variation starts, the game will have the expectation that it will be a big hit once every two games. Can be given to a person. In the case of this embodiment, the variable lottery in S48 of FIG. 7 is drawn with different probabilities depending on whether or not the winning lottery is a win.

(Example 3)
In this embodiment, after executing the lottery in advance, the lottery is executed in accordance with the result. In this embodiment, the lottery is executed in accordance with the result after executing the lottery in advance. Different from 2. Since other configurations and operations are common to the first and second embodiments, differences from the first and second embodiments will be mainly described, and description of the common points will be omitted.

  FIG. 11 is a diagram schematically showing the relationship between the omission of variation omission based on the variation lottery value and the success / failure lottery value and the success / failure determination result in the third embodiment. In this embodiment, it is determined that the symbol variation is omitted when it is 0 to 979 among the variation lottery values of 0 to 999, and it is determined that the symbol variation is executed without omission when it is 980 to 999. Further, when the symbol variation is omitted, it is treated as a failure even if the lottery is not passed, and the success / failure lottery is executed only when the symbol fluctuates without omission to determine whether or not the symbol is correct. In the present embodiment, out of the lottery values from 0 to 999, it is determined that the value is 0 to 499, and the value is 500 to 999. In this way, by executing the random lottery after executing the variable lottery, the symbol variation is not necessarily executed every time the ball enters the start port 62, but a game where the symbol variation can be omitted is realized. it can. As a result, in this embodiment, the symbol variation without omission is executed with a probability of 2/100, and further, it becomes a big hit with a probability of 1/2 in the winning / losing lottery, so that the omission is not made with a probability of 1/100 as a whole. Design variation is made. As a result, it is possible to realize a game that will be a big hit with a probability of about half of the cases where symbol variation is executed without omission, and once the symbol variation starts, the game will have the expectation that it will be a big hit once every two games. Can be given to a person.

  FIG. 12 is a flowchart showing in detail the advance determination process of S28 in FIG. If there is a ball in the starting port 62 (Y in S100), the variable lottery means 113 acquires the variable lottery value (S102), and if the variable lottery value is a result indicating that the symbol variation is not omitted (S104). Y), the success / failure lottery means 112 acquires the success / failure lottery value (S106), and stores the success / failure lottery result and the variable lottery result in the hold control means 116 (S108). The success / failure lottery means 112 may determine whether or not it is successful based on the winner / rejection lottery value and store the result in the hold control means 116 or may store the success / failure lottery value itself. The fluctuation lottery means 113 stores the determination result on whether or not the symbol fluctuation can be omitted based on the fluctuation lottery value in the hold control means 116, but as a modification, the variable lottery value itself may be stored. If there is no entry at the starting port 62 in S100, the processing from S102 to S106 is skipped (N in S100), and if the variation lottery value is a result of omitting symbol variation in S104, S106 is skipped. (N in S104).

Example 4
The present embodiment is different from the first to third embodiments in which different lottery values are used for the success / failure lottery and the variable lottery in that a common lottery value is used for the success / failure lottery and the variable lottery. Since other configurations and operations are the same as those of the first to third embodiments, differences from the first to third embodiments will be mainly described, and description of the common points will be omitted.

  FIG. 13 is a diagram schematically illustrating a relationship between a lottery determination using a common lottery value and a variable lottery in the fourth embodiment. In the present embodiment, among the common lottery values of 0 to 999, it is determined that 0 to 979 is excluded and symbol variation is omitted, 980 to 989 is determined to be excluded, and symbol variation is not omitted, 990 -999 and it is determined that the symbol variation is not omitted. As described above, by using a common lottery value, the winning / losing lottery and the variable lottery can be executed substantially simultaneously. In addition, formally, after acquiring a common lottery value, either the determination of success or failure or the determination of whether or not symbol variation can be omitted may be executed first, and any of them may be executed first for each effect. Does not make a substantial difference. In the present embodiment, the winning or failing lottery is a big hit with a probability of 1/100, and the variable lottery results in omitting the symbol variation with a probability of 98/100. As a result, it is possible to realize a game that will be a big hit with a probability of 1/2 of the cases where symbol variation is executed without omission, and to the player that if the symbol variation starts, it will be a big hit once every two times Can be given.

  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 within the scope of the present invention. is there. Examples of such modifications are given below.

  In each of the above-described embodiments, the present invention has been described by taking as an example a gaming machine that realizes only a transition to a short-time state as a specific game. In the modified example, a gaming machine that further realizes the transition to the probability variation state as the specific game may be used. In this case, the success / failure lottery means 112 refers to a success / failure table in which a relationship different from the relationship between the lottery value and the success / failure result at the normal time as shown in FIGS. In other words, the success / failure lottery means 112 refers to a success / failure table for determining the success / failure based on the normal probability in normal times, and refers to the success / failure table in which the probability of winning is higher than the normal probability when the probability changes. In the first embodiment in which the winning / losing lottery is performed first, the gaming state may differ between the winning timing at the start port 62 and the symbol variation start timing. In particular, there was a possibility that the winning change was in the process of winning, but the jackpot had already appeared at the start of the change and returned to the low probability state. Therefore, even if the winning / losing lottery is made first, it should be a win at that time, but it may not actually be a hit at the start of symbol variation. Therefore, at the pre-judgment processing stage, the lottery value is determined to be out only when the winning lottery value is such that it is out of the high or low accuracy state, and the variable lottery is executed otherwise. It may always be decided not to omit the symbol variation. As yet another modification, the probability of the random lottery may be changed instead of making the probability of winning / failing lottery common between the normal time and the probability variation. For example, in FIG. 11, if the probability of symbol variation is increased without omission compared to the normal time at the time of certainty change, the probability of being successful can be increased without changing the probability of the winning lottery.

  In the above-described certain embodiment, the configuration has been described in which whether or not the symbol variation can be omitted is always determined by the combination of the winning lottery and the variable lottery during the normal game. In a modification, the structure which determines whether the omission of symbol fluctuation | variation in a specific game among normal games is determined may be sufficient. Since the specific game aims to increase the easiness of appearance of the next jackpot, it is preferable that the next win appears as early as possible. In this modification, the symbol variation can be made more efficient by omitting the symbol variation using the variation lottery during the specific gaming state.

  In each of the above embodiments, the present invention has been described with reference to the configuration of a so-called first type pachinko gaming machine. In a modified example, the present invention may be realized in a configuration in which the first type pachinko gaming machine and the second type pachinko gaming machine are combined. For example, in the first embodiment, the grand prize opening 66 is opened instead of omitting the symbol variation. However, in the modified example, a ball is entered into the opened big prize opening 66, and the game ball is placed in the big prize opening 66. A configuration may be adopted in which a special game is generated when a specific area is passed. In addition, the configuration corresponding to the second kind pachinko gaming machine is, for example, similar to the first kind pachinko gaming machine, the symbol is changed, and when the symbol stops at a predetermined stop symbol, the big winning opening 66 is opened for a short time, A configuration may be adopted in which a special game is generated when a game ball that has entered the big prize opening 66 further passes a specific area in the big prize opening 66.

  In each of the above-described embodiments, the configuration has been described in which the result of lottery determination and the result of variable lottery are stored as a holding ball in the holding control means 116 regardless of the result. In the modified example, when the result of the fact that the symbol variation is omitted by the variation lottery, neither the success / failure lottery result nor the variation lottery result may be stored in the holding control means 116. For example, when a new ball enters the starting port 62 during symbol variation, the lottery determination and variation lottery are executed as pre-determination processing at that time, and the result of the lottery control is held only when the symbol variation is not omitted. 116 is stored. In that case, since the fact that the result of lottery is stored means that the symbol variation is not omitted, the variation lottery result may not be stored, or the variation lottery result may be stored together. In addition, the lottery result or the like in the case of the result that the symbol variation is omitted may be configured not to be stored in the hold control unit 116 for a moment, or may be configured to be deleted immediately after being stored once. . In the case of erasing, the lottery holding lamp 20 may be turned on for a short period of time in order to clearly indicate to the player that the lottery has been executed and stored internally. It may be erased after a noticeable display.
