Description

  The present invention relates to a ball game machine such as a pachinko game machine, and more particularly to a correction change process performed in a symbol change display process in a ball game machine equipped with a reel unit.

  Conventionally, among the various ball game machines, a so-called first type pachinko game machine is displayed while changing a plurality of symbols in a display area of a display device provided substantially at the center of the game board. (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 the combination of symbols when a plurality of rows of symbol variations are stopped becomes a specific mode. Known as a thing. In recent years, a display device composed of a liquid crystal display has become the mainstream as a display device for displaying such a plurality of rows of symbol variations, but there are also devices composed of mechanical display means such as a drum rotary type. (For example, refer to Patent Document 1). The variable display of symbols in the display area is not limited to simply displaying multiple symbols in a variable manner, but the time required for the variable display to be a big hit if one more symbols are aligned, such as 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 sense of expectation is enhanced by control of changing the probability to increase the efficiency of transition to special games, shortening the variation time, and shifting to the easy-to-enter state to increase the ease of entering the starting prize opening.

  By the way, in a gaming machine equipped with a drum rotation type display device, a plurality of symbols are arranged along the peripheral surfaces of a plurality of rows of reels, and each reel is individually driven to rotate by a driving means such as a stepping motor. Then, the result of the lottery determination is indicated by a combination of symbols that are stopped on the active line when the reels of the plurality of rows are stopped. In such a gaming machine, unlike the image display on the liquid crystal display, the symbols arranged on each reel must be physically changed and the determined symbols must be presented to the player. For this reason, it is necessary to sequentially grasp which symbols are presented to the player on each reel (positioned on the effective line). Therefore, the reel unit including the plurality of rows of reels and the driving means is provided with a detection device for detecting the reference position of each reel. The control device of the gaming machine determines the reference position of each reel based on the detection signal output from the detection device, and the symbol on the effective line at an arbitrary timing based on the number of motor driving steps based on that position. The symbol indicating the result of the lottery recognition can be stopped on the active line.

  On the other hand, since symbol variation is executed according to a variation pattern determined in advance, the symbol indicating the result of the lottery must be stopped when the variation time determined by the variation pattern expires. The amount of reel rotation control differs depending on the symbol located at. Therefore, in general, a correction variation for adjusting the position of the reel, that is, the alignment of the symbol, is performed at a predetermined timing in the symbol variation process.

JP 2001-346963 A

  Such symbol position correction generally refers to a correction table in which a correction variation pattern is determined in accordance with the difference in the number of symbols between a symbol to be stopped based on the result of the lottery determination and a symbol displayed on the active line. Is done. In the technique described in Patent Document 1, two types of reel rotation speeds at the time of correction are set, and the correction table set so as to change the ratio of the rotation times according to the number of symbols is stopped. The scheduled symbol is stopped at the determined stop timing.

  However, when such a patterned correction variation is made, depending on the expert, the symbol to be stopped can be determined from the symbol at the start of correction and the variation pattern, and the result of the lottery can be determined in the middle of the symbol variation There is. As a result, there is a concern that the gaming interests of skilled workers will be reduced.

  The present invention has been made in view of such problems, and a main object of the present invention is to provide a technology that makes it difficult to determine a stop symbol even if symbol position correction is executed in a ball game machine equipped with a reel unit. There is to do.

  In order to solve the above problems, a ball game machine (10) according to an aspect of the present invention is provided at a predetermined position of a game board (50) in which a game area (52) is formed and a game area (52). The game ball is provided at a predetermined position of the start opening (62) and the game area (52) that triggers the winning / losing lottery, and is opened according to the result of the winning / losing lottery. A special winning symbol (66) that triggers a payout, a special symbol display device (61) that displays a special symbol (192) indicating the result of the winning / failing lottery, and a plurality of symbols (for example, examples) along the circumferential surface And a plurality of reels (206a, 206b, 206c) in which at least a part of the peripheral surface thereof is arranged so as to be presented to the player. Drive means capable of individually driving each reel (for example, the mode of the embodiment) 217), and a combination of symbols that are stopped on a predetermined effective line (for example, effective lines L1 to L5 in the embodiment) when the reels (206a, 206b, 206c) of the plurality of rows are stopped. Display symbol determination means for determining symbols positioned on the effective line in each of the reel unit (60) indicating the result of the lottery determination by the decorative symbol (190) and the reels (206a, 206b, 206c) in a plurality of rows (for example, embodiment) Effect determining means 132), a main control device (for example, the main board 102 of the embodiment) for mainly controlling the basic operation of the game including the lottery process, and a game effect including a display process for indicating the result of the lottery process And a sub-control device (for example, the sub-board 104 in the embodiment) that mainly controls the general operation.

  The main control device (main board 102) determines the variation pattern that defines the variation time of the special symbol (192) and the validity lottery means (112) that executes the lottery lottery upon entering the starting port (62). The variation pattern determining means (115) to perform, the special symbol display control means (for example, the main display control means 118 of the embodiment) for controlling the variation display of the special symbol (192), and the result of the winning / failing lottery become a big hit, and the special symbol ( Special game control means (120) for executing a special game that is more advantageous to the player than the normal game by opening the big prize opening (66) when 192) is stopped and displayed in a manner indicating a big hit; The information indicating the result of the lottery determination and the information indicating the determined variation pattern are transmitted to the sub-control device (sub-board 104), and when the variation of the special symbol (192) starts, the variation start code is transmitted. Control command transmission means (for example, the lottery means 112 and main display control means 118 of the embodiment) for transmitting a variable stop command to the sub-control device (sub-board 104) when the special symbol (192) is stopped. including.

  The sub-control device (sub-board 104) has a plurality of rows of symbols (for example, the left symbol 191 and the middle symbol 193 of the embodiment) that are stopped and displayed as decorative symbols (190) on the effective line (for example, the effective lines L1 to L5 of the embodiment). , Right symbol 195) as a combination of stop symbol pattern storage means (for example, symbol pattern determining means 131 of the embodiment) that holds a plurality of symbol patterns, and variation from the start of change to stop in the variation display of the decorative symbol (190) Based on the variation effect pattern storage means (for example, the pattern storage means 130 in the embodiment) that holds a plurality of variation effect patterns for which the process is determined, and the received information indicating the lottery result, any one of the plurality of stop symbol patterns is selected. Decorative symbol determining means for selecting (for example, the symbol pattern determining means 131 of the embodiment) and information indicating the received variation pattern Next, an effect determining means (132) for selecting one of a plurality of change effect patterns, and a drive means (for example, the motor 217 of the embodiment) when receiving a change start command, a plurality of reels (206a, 206b, 206c). ) Is started to display the variation of the decorative symbol (190), the decorative symbol (190) is variably displayed according to the selected variation effect pattern, and when a variation stop command is received, a plurality of reels (206a) are displayed. , 206b, 206c), and display control means (for example, effect display control means 134 in the embodiment) for stopping and displaying the decorative symbol (190) in the determined symbol combination.

  The effect determining means (132) changes the symbol corresponding to the determined stop symbol pattern to stop it on the effective line (for example, the effective lines L1 to L5 in the embodiment) when the variable stop command is received. It is a table that is referred to in order to execute correction fluctuations for adjusting the fluctuation speed and fluctuation amount of a plurality of columns of symbols (for example, left symbol 191, middle symbol 193, right symbol 195 in the embodiment) in a predetermined correction period. Thus, a plurality of types of correction variation patterns that define the reel rotation speed and the amount of rotation at each rotation speed that are changed stepwise in the correction period are selected and selected on the effective line (for example, the effective lines L1 to L5 in the embodiment). ) Holds a correction table in which different correction variation patterns are associated with each other according to the difference in the number of symbols between a symbol being displayed and a symbol to be displayed later. Also, as a correction table, a basic correction table that is defined so that one of a plurality of types of correction variation patterns is selected according to the difference in the number of symbols, and one of a plurality of types of correction variation patterns is selected by pattern lottery. And a lottery correction table defined so as to hold. Then, when determining the correction variation pattern, during the correction period, the symbol to be stopped corresponding to the determined stop symbol pattern and the symbol displayed on the active line (for example, the effective lines L1 to L5 in the embodiment) are displayed in the correction period. The number of symbols at the time of correction, which is the number of symbols to be displayed on the effective line (for example, the effective lines L1 to L5 in the embodiment), is calculated, and variable correction that is a correction fluctuation pattern in the second half is performed by pattern lottery using a lottery correction table Determine the variation pattern, determine the number of symbols in the lottery progress as the difference in the number of symbols corresponding to the variable correction variation pattern, and refer to the basic correction table according to the difference in the number of symbols between the number of symbols in progress and the number of symbols in the lottery progress Then, the basic correction fluctuation pattern which is the first half correction fluctuation pattern is determined.

  The display control means (effect display control means 134) rotates each reel in accordance with the determined basic correction change pattern during the correction period during the change display of the decorative design (190), and then the determined variable correction change. Each of the reels is rotated according to the pattern, and a plurality of symbols (for example, the left symbol 191, the middle symbol 193, and the right symbol 195 in the embodiment) are changed.

  Here, one “effective line” may be formed in a region presented to a player of a plurality of rows of reels, or a plurality of “effective lines” may be formed simultaneously. The “decorative symbol” is composed of a combination of symbols of each reel located on the effective line, and indicates the result of the lottery determination based on the symbol combination. The “display symbol determination means” determines a symbol positioned on the effective line in each reel. For example, the display symbol determination means obtains detection information from a rotational position detection device that detects the position of each reel at a plurality of locations in the rotation direction. The arrival of the effective line may be determined for a plurality of symbols on each reel. More specifically, for example, the position of the detected reel is associated with the symbol positioned on the effective line, and any symbol in each reel is detected by detecting any one of a plurality of positions. May be determined on the effective line, that is, the symbol positioned on the effective line in each reel may be determined. In that case, if the positions of multiple locations on each reel are associated with all of the multiple symbols arranged on the peripheral surface of the reel, the resolution for determining the symbol that reaches the effective line will be high. Is preferable. For example, a sensor may be installed on the main body (fixed side) of the reel unit, and a plurality of detection pieces corresponding to all symbols may be provided on each reel. In addition, the position of multiple locations on each reel is associated with multiple reference symbols that are part of multiple symbols arranged on the peripheral surface of the reel, and it is determined which reference symbol has reached the active line It is good also as a possible structure. Then, it may be determined from the amount of rotation of the reel based on the position of each reference symbol that the remaining symbols have reached the effective line.

  The “main control device” may be a device that mainly controls basic operations such as a control relating to the appearance, such as a lottery process and a special symbol display process that directly indicates the lottery result. The “sub-control device” may be a device that mainly controls an effect operation such as a display process of a decorative symbol that shows an effect of the lottery based on information received from the main control device. The communication between the main control device and the sub control device may be configured to be one-way communication from the main control device to the sub control device. The “decorative symbol” is controlled so as to start changing in a manner linked to the special symbol and to end the variation.

  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 the one data can be specified or a recording format thereof. The “correction variation pattern” defines a variation process of correction variation that is executed in a correction period during symbol variation. The rotation amount in the correction variation pattern may be defined by a rotation angle or a rotation movement amount (rotation length). For example, when the driving means is a stepping motor, the rotation amount may be defined by a control amount such as the number of rotation steps of the motor. The “basic correction table” is a table set so that the correction variation pattern is determined in accordance with the difference in the number of symbols between the symbols currently displayed on the effective line and the symbols to be subsequently displayed on the effective line for each reel. According to this basic correction table, the correction variation pattern is specified according to the symbol number difference without lottery. On the other hand, the “lottery correction table” is a table set so that the correction variation pattern is determined by lottery. According to the lottery correction table, the correction variation pattern can be given randomness regardless of the number of symbols. The “variable correction fluctuation pattern” is a correction fluctuation pattern temporarily determined by the lottery correction table, and the “basic correction fluctuation pattern” is a correction fluctuation pattern temporarily determined by the basic correction table. The actual correction variation pattern is obtained by adding the rotation amount at each rotation speed in the determined basic correction variation pattern and the rotation amount obtained by adding the rotation amount at each rotation speed in the determined variable correction variation pattern. This is the corrected rotation amount at each rotation speed.

  According to this aspect, when determining the correction variation pattern, a basic correction variation pattern that is a temporary correction variation pattern according to the number of symbols and a variable correction variation pattern that is a temporary correction variation pattern by lottery are determined. . Then, the actual correction fluctuation pattern is determined in such a manner that the variable correction fluctuation pattern is continued to the basic correction fluctuation pattern. Thereby, the correction fluctuation according to the variable correction fluctuation pattern is executed following the correction fluctuation according to the basic correction fluctuation pattern. In particular, after the variable correction variation pattern is randomly determined by lottery, the basic correction variation pattern is determined so as to match the number of symbols according to the number of symbols in the variable correction variation pattern lottery progress, so one correction A combination of a plurality of types of basic correction variation patterns and variable correction variation patterns can be selected with respect to the number of time progression symbols. That is, even when the number of symbols at the time of correction is the same, it is possible to give randomness (variation) to the rotation time of the reel at each stage. As a result, even if it is an expert, a stop symbol cannot be easily discriminate | determined only by seeing the correction | amendment fluctuation | variation, and the game entertainment interest can be maintained now.

  The effect determining means (132) is a table set so that the reel rotation speed at the final stage of the basic correction table is equal to the reel rotation speed at the first stage of the lottery correction table as the basic correction table and the lottery correction table. May be held.

  According to this aspect, it becomes difficult to discriminate the boundary between the last stage correction fluctuation of the basic correction fluctuation pattern and the first stage correction fluctuation of the variable correction fluctuation pattern. It is difficult to specify the variation pattern.

  The effect determining means (132) holds a table in which the total correction time of all stages is set equal regardless of the number of symbols as a basic correction table, and the total correction time of all stages as a lottery correction table. May hold a table set equal regardless of the difference in the number of symbols.

  According to this aspect, the correction time obtained by combining the basic correction variation pattern and the variable correction variation pattern can always be kept constant. Therefore, the execution period of the correction variation is constant during the symbol variation according to the determined variation pattern. Can be held for a period.

  The effect determining means (132) may include a first basic correction table and a second basic correction table in which the correction period is set shorter than the first basic correction table as the basic correction table. In addition, as the lottery correction table, the first lottery correction table associated with the first basic correction table and the second lottery correction table associated with the second basic correction table and having a correction period shorter than the first lottery correction table are set. And a lottery correction table. Then, the basic correction table and the lottery correction table may be set so that the correction period falls within the fluctuation time of the fluctuation pattern determined according to the gaming state.

  According to this aspect, when a variation occurs in the variation time length of the variation pattern according to the gaming state, the game is achieved by setting a correction table that matches the variation time length as the basic correction table and the lottery correction table. It becomes possible to realize correction fluctuations flexibly corresponding to the state. In other words, the correction variation can be completed even if the gaming state changes. For example, when the gaming state is a short time to be described later, a second basic correction table and a second lottery correction table in which the correction period is set short may be set.

  Alternatively, the effect determining means (132) may include a normal lottery correction table and a specific lottery correction table in which the correction period is set longer than the normal lottery correction table as the lottery correction table. A normal lottery correction table may be set in a normal gaming state, and a specific lottery correction table may be set in a predetermined specific gaming state.

  According to this aspect, by setting the specific lottery correction table in a specific gaming state, it is possible to cause the player to recognize a correction variation different from normal. For example, by setting the specific lottery correction table when the result of the lottery determination becomes a predetermined specific result, the player can predict the specific result, and the correction variation is noticeable. It can also be used. For example, the specific lottery correction table may be set in response to the fact that the winning / losing lottery value serving as a specific jackpot is suspended.

  Another embodiment of the present invention is also a ball game machine (10). The ball game machine (10) is provided at a predetermined position of the game board (50) in which the game area (52) is formed and the game area (52), and the entry of the game ball serves as an opportunity for the success / failure lottery.

When the result of the variation pattern determining means (115) and the winning / losing lottery is a big hit, and the combination of symbols is stopped and displayed in a mode showing a big hit, the player is given a game more than the normal game by opening the big winning opening (66). Special game control means (120) for executing a special game that is in an advantageous state, and an active line (for example, the effective line of the embodiment) 1 to L5) stop symbol pattern storage means for holding a plurality of stop symbol patterns as combinations of symbols (for example, the left symbol 191 of the embodiment, the middle symbol 193, and the right symbol 195). A pattern mode determining unit 131), a variation effect pattern storage unit (for example, the pattern storage unit 130 of the embodiment) that holds a plurality of variation effect patterns in which a variation process from the start to stop of the variation in the symbol variation display is defined; Based on the result of the lottery determination and the determined variation pattern, an effect determination means (132) for selecting one of the plurality of variation effect patterns, and a symbol is variably displayed according to the variation effect pattern, and a plurality of reels (206a, 206b, 206c) are stopped, and a plurality of symbols (for example, the left symbol 191 of the embodiment, the middle symbol 1) Display control means (for example, effect display control means 134 of the embodiment) that stops and displays the right symbol 195) in the determined symbol combination.

  The effect determining means (132) displays the symbols in a variable manner according to the changing effect pattern, and enables a plurality of columns of symbols (for example, the left symbol 191 in the embodiment, the middle symbol 193, and the right symbol 195) in the determined symbol combination. In order to stop on the line (for example, the effective lines L1 to L5 in the embodiment), a plurality of columns of symbols (for example, the left symbol 191 in the embodiment, the middle symbol 193, and the right symbol 195) in a predetermined correction period during the variation of the symbol. A table that is referred to in order to execute correction fluctuations for adjusting the fluctuation speed and fluctuation amount, and is a plurality of types that define the reel rotation speed and the rotation amount at each rotation speed that are changed stepwise in the correction period. According to the difference in the number of symbols between a symbol currently displayed on an effective line (for example, effective lines L1 to L5 in the embodiment) and a symbol to be displayed later, with a correction variation pattern as a selection target. Consisting correction variation pattern holds the correction table associated.

[Example 1]
The pachinko gaming machine of the present embodiment has a gaming property equivalent to the conventional type 1 pachinko gaming machine, and in order to realize the gaming property, a start winning opening, a special symbol display device, a holding lamp, and a reel unit are provided. Prepare. That is, this pachinko gaming machine includes a so-called drum rotation type display device, and the display device includes a plurality of rows of reels having a pattern arranged on the peripheral surface, and a motor that can individually drive each reel. It is configured as a unit. When the game ball enters the start winning opening, a winning / losing lottery is executed, and when the winning / losing lottery result is a “hit”, a special game in which the large winning opening is repeatedly opened and closed is started. When a big prize opening is opened and a game ball enters, a predetermined number of prize balls are paid out each time, and the player can obtain a large profit. The result of the winning / failing lottery is directly displayed in the form of a variation display of a special symbol, while being displayed in the form of a decorative symbol composed of a combination of three symbols. The special symbol and the decorative symbol are associated with each other as indicating the same winning / losing lottery result, and control is performed so that the variation start timing and the variation stop timing also coincide.

  In such a gaming machine, it is necessary to stop the decorative symbols in accordance with the fluctuation stop timing in a form showing the result of the lottery. However, since the decorative symbol at the variation start timing changes for each variation, if the reel is rotated at a constant speed and stopped at the variation stop timing at which the determined variation time expires, the decorative pattern is determined as a stop mode. It is difficult to stop at. Therefore, in general, symbol position correction is performed according to the symbol number difference between the symbol to be stopped based on the result of the lottery determination and the symbol displayed on the active line. However, if the correction variation is patterned only according to the difference in the number of symbols, there is a possibility that the stop symbol and consequently the result of the lottery determination can be determined from the symbol at the start of correction and the length of the correction variation. is there. Therefore, in this embodiment, by devising a method for determining the correction fluctuation pattern for the correction fluctuation executed during the symbol fluctuation, it becomes difficult for the player to determine the correction fluctuation pattern. Avoid situations where the results are distracted and the gaming interest is reduced. Hereinafter, such a configuration will be described.

  FIG. 1 shows a basic structure on the front side of a 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 outer frame 11 has an opening and is a frame for fixing the pachinko gaming machine 10 to a position where it should be installed. The front frame 12 is a frame body that aligns with the opening portion of the outer frame 11, and is attached to the outer frame 11 so as to be opened and closed by a hinge mechanism (not shown). The front frame 12 includes a mechanism for launching a game ball, a mechanism for detachably storing a game board, a mechanism for guiding or collecting the game ball, and the like.

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 or the like is output by means for controlling an effect described later.

  The game board 50 has an out port 58, a special symbol display device 61, a reel unit 60, 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 are included. Furthermore, in the game area 52, a plurality of mechanisms such as a game nail and a windmill (not shown) are installed.

  The starting port 62 is a starting port that triggers the entrance of a game ball to perform a lottery determination. The starting port 62 is provided in the starting port 62 and a start winning detection device 74 for detecting the entrance of a game ball. A normal electric accessory solenoid 76 for expanding the expansion mechanism 63 (so-called electric tulip) is provided. The expansion mechanism 63 is composed of two blade members provided at the upper part of the opening of the start port 62, and has a narrow opening width that allows only a game ball falling from just above the start port 62 to enter when closed. Become. On the other hand, when the expansion mechanism 63 is expanded and opened, the opening width of the start port 62 is widened, and not only the start port 62 but also a game ball falling in the vicinity thereof can be guided to the start port 62 and can enter. Ease is improved. This lottery determination is a lottery for determining whether or not to shift to a special game that is more advantageous to the player than a normal game, and is executed every time there is a ball entering the start port 62. The start winning detection device 74 is a sensor that detects the entry of a game ball into the start port 62, and generates start win information indicating the winning at the time of entering.

  The general winning opening 72 includes a general winning detecting device 73 for detecting the entering of a game ball. The general winning detection device 73 is a sensor that detects the entry of a game ball into the general winning opening 72, and generates general winning information indicating the winning at the time of winning.

  The special winning opening 66 includes a winning detection device 78 for detecting the entry of a game ball and a special winning opening solenoid 80 for opening 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” in a special game that starts when the special symbol 192 stops in a predetermined manner. The big winning opening 66 is provided at a position above the out opening 58, for example. The number of the big winning openings 66 is not limited to a single arrangement, and a plurality of large winning openings 66 may be installed and used depending on the gaming state or 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 is a display device that is provided on the left side of the game area 52 and displays a special symbol 192 that indicates the result of the lottery determination. In this embodiment, the special symbol display device 61 includes 7-segment LEDs. The special symbol 192 is a symbol corresponding to the result of the lottery performed when the game ball falls into the start port 62. When the symbol mode when the special symbol 192 is stopped is the symbol that is determined in advance, the timing at which the symbol is displayed is the big hit occurrence timing. The stop symbol is a symbol to be displayed at the end of symbol variation. The special symbol 192 in the present embodiment is represented by numbers, characters, symbols such as “0” to “9” that are hit symbol patterns, or a symbol “−” that is an off symbol pattern. These numbers or symbols are replaced one after another at a high speed and displayed on the special symbol display device 61, whereby the symbol variation display of the special symbol 192 is realized.

  Note that the special symbol 192 is not limited to the above numbers or symbols, and may be letters such as English letters, or may be a generally meaningless symbol formed by a combination of segments constituting a 7-segment LED. May be. Further, the 7-segment LED may be composed of 8 segments including 7 segments forming “eight-letter shape” and 1 segment representing “dot”. In this case, a numerical value for 8 bits can be expressed by combining 8 segments. Further, the special symbol display device 61 may be an LED dot array that is not a 7-segment LED, and a plurality of types of special symbols 192 may be expressed by combinations of lighting patterns and lighting colors.

  The reel unit 60 is a drum rotation type display device that is provided substantially at the center of the game area 52 and displays the decorative symbol 190 in a manner that changes the 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 reel unit 60 includes, as decorative symbols 190, a plurality of rows of reels that vary a plurality of rows of symbols simulating a game of a slot machine, and a stepping motor as drive means that can individually drive the reels. In this embodiment, three rows of reels are provided for varying the three symbols of the left symbol 191, middle symbol 193 and right symbol 195, and "0" to "6" are provided along the outer peripheral surface of each reel. Numeric symbols and a blank symbol consisting of a symbol “*” are arranged. Since the blank symbols “*” are arranged between numerical symbols arranged in ascending order or descending order, a total of twelve symbols are arranged along the outer peripheral surface of each reel.

  However, the numerical symbol in this embodiment is a symbol that becomes a part of the stop symbol combination for indicating the result of the success / failure lotion, whereas the blank symbol is a part of the stop symbol combination for indicating the result of the success / failure lottery. It is different in that it is a design that should not be used. That is, the number symbol indicates that the result of the lottery win is a win when a stop symbol combination formed when a plurality of symbols are stopped on the same line becomes a winning symbol combination. On the other hand, even if a plurality of blank symbols are stopped on the same line, the result of the winning / failing lottery is not shown, and the number of lines that can display the stop symbol combinations of the stop symbol candidates is limited by the stop. To work. Details of the reel unit 60 will be described later.

  Here, since the special symbol 192 does not necessarily have an effect role, in the present embodiment, the special symbol display device 61 on the lower left side of the reel unit 60 is displayed in an inconspicuous size. However, in the case of adopting a technique in which the special symbol itself has an effect role to express without using the decorative symbol, the special symbol may be displayed on the liquid crystal display instead of the 7-segment LED.

  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 that determines whether or not the expansion mechanism 63 is expanded. 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. Therefore, the open lottery is also called “ordinary symbol lottery”. The normal symbol display device 59 in this embodiment is composed of two lamps for convenience, and the display state of the normal symbols is expressed by which of these lamps is lit. For example, when the first lamp is turned off and the second lamp is hit, the normal symbol fluctuation display is expressed by alternately turning on and off, and finally one of the lights is turned on. A stop symbol of a normal symbol is expressed by being stopped in the state.

  The normal symbol display device 59 is provided at the lower right of the reel unit 60. After a predetermined time has elapsed since the start of the change, the normal symbol change display stops. At this time, in the normal state, the normal symbol stops at the winning symbol with a low probability of, for example, about 1/256, and in the easy entry state described later, the normal symbol is in the winning symbol with a high probability of, for example, about 250/256. Stop. When the normal symbol stops at the winning symbol, the expansion mechanism 63 is expanded for a predetermined time. The opening time of the spreading mechanism 63 is, for example, 0.1 seconds in the normal state, and 6 seconds in the easy entry state.

  A center ornament 64 is provided around the reel unit 60. The center decoration 64 has functions such as a flow path of the game ball, protection of the reel unit 60, and decoration. The special symbol hold display device 20 is provided at the lower left portion of the game area 52, and the normal symbol hold display device 22 is provided below the normal symbol display device 59 at the lower right portion of the game area 52, which is the symmetrical position. ing.

  The special symbol hold display device 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. When the number of lottery holds is three, the symbol variation time in the case of a loss is shortened from the normal time in order to increase game efficiency (hereinafter also referred to as “shortening variation”). Similarly, when the number of pending lottery holds is 4, in order to further increase the game efficiency, the symbol variation time in the case of losing is further shortened than in the case of the above 3 (hereinafter also referred to as “super shortened variation”). ).

  The normal symbol hold display device 22 is also composed of four lamps, and displays the number of normal symbol fluctuation hold 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.

  Game effect lamps 90 are provided above and below the reel unit 60, respectively. The operation button 82 is an operation input unit that is operated by the player to input a predetermined instruction to the gaming machine, and changes are made to the contents of the effect according to the contents of the operation input. The operation button 82 is provided on the outer wall surface near the upper ball tray 15. Although the operation button 82 in this embodiment is composed of one button, it may be composed of a plurality of buttons and direction instruction buttons such as a cross key.

  An outline of a game method and a control flow performed in the above configuration will be described. 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 launch handle 17 by hand, the launch of the game ball is repeated 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 reel unit 60. The variation display of the special symbol 192 and the decorative symbol 190 is stopped after the lapse of the variation display time determined prior to the display. The special symbol 192 is variably displayed in accordance with a variation pattern in which a variation mode from the variation start to the stop is determined. The decorative symbol 190 is variably displayed according to a variation effect pattern in which a variation mode from the start to the end of the variation is determined. A plurality of types of variation patterns and variation production patterns are prepared, and each has various variation times. While the special symbol 192 is variably displayed according to the variation pattern, the decorative symbol 190 is variably displayed according to the variation effect pattern having the same variation time. In the variation pattern, a variation display time is determined for each pattern as an end condition of the symbol variation, and the variation of the special symbol 192 and the decorative symbol 190 is stopped when the variation display time elapses.

  As a variation display of the decorative symbol 190, first, as the variation starts, the symbols are varied in all three columns like the reel rotation of the slot machine, and when it approaches the variation end timing, it is stopped one by one as a final stop mode. The symbol combination is displayed. When the special symbol 192 and the decorative symbol 190 at the time of the stop are in a stop mode 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. The The stop mode of the decorative symbol 190 indicating the big hit is, for example, a mode of combination (hit symbol combination) in which three types of symbols match.

  The variation effect pattern includes a normal loss effect pattern, a reach failure effect pattern, and a reach jackpot effect pattern. The normal off effect pattern is an effect pattern for displaying a normal off symbol combination. The reach out effect pattern is an effect pattern for displaying an out symbol combination through a reach state, which is a big win if one more symbols are arranged. The reach jackpot effect pattern is an effect pattern when displaying a jackpot symbol combination through the reach state. In particular, the patterns when reaching the reach state include patterns with various long and short fluctuation times. Reach patterns with relatively short fluctuation times are called “normal reach”, and reach patterns with long fluctuation times are called “super reach”. ".

  The special game is started by an effect display called a start demonstration effect. After the start demonstration effect is displayed, the special winning opening 66 is opened, and after the opening lasts for about 30 seconds, or after nine or more game balls are dropped, it is temporarily closed. From such opening to closing of the big prize opening 66 is basically called a unit game, but it may be repeated a plurality of short-time opening during one unit game. After the special winning opening 66 is opened and closed or the unit game is repeated a predetermined number of times, for example, 15 times, the special game is ended by an effect display called an end demo effect. Note that the start demonstration effect and the end demonstration effect in the present embodiment are performed by predetermined lighting and blinking display of the game effect lamp 90 and the reel unit 60, which will be described later, and a specific driving mode of the reel. On the other hand, when the winning lottery corresponds to a result called “small hit”, the small hit game is executed. The small hit is a result included as a result of the lottery. The small hit game is a unit game executed in a manner similar to some types of special games. However, the unit game executed as a small hit game is only one time, which is different from a special game in which a plurality of unit games are executed.

  In the normal game after the end of the special game, the fluctuation time of the special symbol 192 and the decorative symbol 190, which are one of the specific games, is started (hereinafter referred to as “time reduction” as appropriate). The time shortening of the special symbol 192 and the decorative symbol 190 is a state in which the variation time of the special symbol 192 and the decorative symbol 190 is shortened from the normal state. The variation time of the special symbol 192 and the decoration symbol 190 is returned to the original variation time after a predetermined variation number, for example, 100 variation display, but if the big hit occurs before the variation number is reached, the time is shortened. Also ends. Due to the shortening of time, the variation time of the special symbol 192 and the decorative symbol 190 is shortened, so that it is possible to shorten the time until the big hit occurs compared to the normal state where the symbol variation is performed with the normal variation time. Therefore, it is possible to relatively increase the jackpot acquisition ease.

  During the time shortening of the special symbol 192 and the decorative symbol 190, the easy entry state which is one of the specific games is performed. The easy entry state is a state in which the ease of entering the starting port 62 is enhanced by executing the short time of the normal symbol, the probability variation of the open lottery, and the open extension of the expansion mechanism 63. The normal symbol time reduction is a state in which the variation time of the normal symbol is shortened from the normal state. The probability variation of the open lottery is a state in which the winning probability of the open lottery is higher than the normal state. The opening extension of the spreading mechanism 63 is a state in which the opening time of the spreading mechanism 63 is longer than the normal state. As described above, in the easy entry state, the possibility that the number of fluctuations of the normal symbol per certain time increases as compared to the normal state increases, and the ease of entering the start opening 62 also increases. There is a high possibility that the number of entering will increase. Therefore, due to the shortened time of the special symbol 192 and the decorative symbol 190 and the easy entry state, the chance to obtain a winning ball by entering the starting port 62 increases during that period, and as a result, the player can play the game with little decrease in possession. It is possible to continue.

  Note that the easy entry state in the present embodiment increases the ease of entering the starting port 62 by using three functions such as a short time for a normal symbol, a probability variation of an open lottery, and an open / extended extension of the expansion mechanism 63. However, as a modification, it is good also as a structure which improves the entrance ease to the starting port 62 using one or two functions among these three functions. Thus, even if only a part of the three functions is used, it is possible to improve the ease of entering the starting port 62. Moreover, it is good also as a structure which switches according to a gaming state at least any one of three functions by the period to implement and the period which does not implement.

  When a special game occurs and the winning stop pattern at that time is in a specific mode, the probability variation game of the winning lottery (hereinafter referred to as “probability change” as appropriate) that is one of the specific games after the end of the special game ) Is further started. During the chance change of the winning / failing lottery, the winning / failing lottery with a higher probability of winning than the normal probability state is performed, and a new special game can be generated relatively early. The probability change of the success / failure lottery is continued until the next big hit occurs, but as a modification, it may be configured to end when a predetermined limited number of symbol changes are made. In this embodiment, the special symbol 192 and the decorative symbol 190 are started at the same time as when the probability change is started, and the easy entry state is also started. May be executed.

  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 controls the display contents on the reel unit 60 and the lighting of the game effect lamp 90. In particular, the display contents are changed in accordance with the lottery result by the main board 102, and the game effect lamp 90 is changed in accordance with the progress of the production. Activate lighting. The main board 102 and the sub board 104 constitute a game control device 100. The back setting mechanism 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, a reel unit 60, a normal symbol display device 59, an operation button 82, The speaker 18, the game effect lamp 90, and the RAM clear switch 92 are electrically connected to each other so that various control signals can be transmitted and received. The game control apparatus 100 controls not only the basic operation of the game, but also staging operations such as symbol variation display and electrical decoration. The game control device 100 includes a main board 102 (which functions as a “main control device”) that controls the overall operation of the pachinko gaming machine 10 including basic operations of the game, and a sub board 104 (the “sub-board” that controls the effects of symbols, etc. Function as a “control device”). 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 is a ball determination unit 110, a winning / failing lottery unit 112, a symbol determination unit 114, a variation pattern determination unit 115, a hold control unit 116, a main display control unit 118, a special game control unit 120, a specific game. An execution unit 122, an open / close control unit 124, a main state storage unit 126, an initialization execution unit 127, and a power interruption return control unit 128 are provided. Is provided. The sub-board 104 in this 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 a position determination 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.

  However, since data transmission / reception between the main board 102 and the sub board 104 is unidirectional from the main board 102 to the sub board 104, each operation is performed so that the entire operation is realized by such data transmission / reception in one direction. The configuration is arranged on the main board 102 and the sub board 104. In this way, since the unidirectionality of data transmission from the main board 102 to the sub board 104 is maintained, data cannot be transmitted from the configuration included in the sub board 104 to the configuration included in the main board 102. It is not possible to request data transmission. Therefore, the information generated on the main board 102 cannot be referred to from the sub board 104 unless the main board 102 unilaterally transmits the information to 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 obtains, as a success / failure lottery value, a random number value for determining whether or not to shift to a special game that is more advantageous to the player than the normal game when the starting hole 62 is entered. To do. For example, the success / failure lottery value is acquired from a value range from “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 value acquired as the success / failure lottery value by the success / failure lottery means 112 is temporarily held by the hold control means 116. However, the lottery value is held within a range not exceeding the predetermined holding upper limit number.

  The success / failure lottery means 112 holds a plurality of success / failure determination tables referred to in the determination of success / failure. In the plurality of success / failure determination tables, determination results of big hits, small hits and misses, and winning / failing lottery values are associated with each other, and the success / failure probabilities are determined according to the associated jackpot range settings. The success / failure lottery means 112 refers to the success / failure determination table based on the normal probability at the normal time, and refers to the success / failure determination table whose winning probability is higher than the normal probability when the probability changes. The success / failure lottery means 112 refers to any of the plurality of success / failure determination tables, and determines whether or not the success / failure lottery value is a win.

  The success / failure lottery means 112 acquires a lottery value as an open lottery for determining a normal symbol when the game ball passes through the operation port 68. The success / failure lottery means 112 holds a success / failure table in which the correspondence between the lottery value of the open lottery and the success / failure result is determined, and determines the success / failure result of the open lottery with reference to the success / failure table. In the normal state, the winning / failing table with a probability of 1/256 is referred to, and in the easy entry state, the winning / failing table with a probability of 250/256 is referred to. The lottery value of the normal symbol is temporarily held by the hold control means 116. However, the lottery value is held only when the predetermined hold upper limit number held by the hold control means 116 is not exceeded.

  FIG. 4 is a diagram schematically showing the success / failure determination table. The success / failure determination table in this figure associates determination results of big hits, small hits and misses, and winning / failing lottery values. Depending on the respective range settings, the hit / failure probabilities of big hits and small hits are determined. Is determined. The success / failure lottery means 112 refers to the success / failure determination table of FIG. In the success / failure lottery performed by the success / failure lottery means 112, in the normal state, as shown in FIG. 4 (a), only when the success / failure lottery value falls within the range of 0 to 399 is a big hit. At the time of certainty change, as shown in FIG. 4B, the range of the big hit is expanded, and not only when the winning / losing lottery value falls within the range of 0 to 399 but also when the lottery falls within the range of 400 to 2999. Thus, the range corresponding to the big hit changes according to the gaming state. In the case of hitting a big hit, whether it is a 15R big hit or a 2R big hit and whether or not there is a probability change is determined separately according to the stop symbol of the special symbol. In this figure, the single hit / fail judgment table shows the big hit range for both normal time and probability change, but the success / fail judgment table may be prepared separately for normal time and for probability change.

  In the present embodiment, even if the winning / raising lottery value does not correspond to the big hit range, that is, a so-called out of range, it becomes a small hit if it falls within the predetermined range. In the example of this figure, when the success / failure lottery value acquired by the success / failure lottery means 112 falls within the range of 65000 to 65535, it is a small hit. In this way, if it does not correspond to the big hit, it is all “out”, but in the example in this figure, the winning lottery value range when it does not correspond to the small hit out of the cases where it does not correspond to the big hit Is expressed as “displacement”. In addition, although the example which implement | achieved the determination table of whether it is a big hit and the determination table of whether it is a small win in the figure in the form of a single winning / nothing determination table was shown in this figure, each may be implement | achieved as a separate table. Good.

  Returning to FIG. 3, 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 winning / failing lottery means 112 is displayed variably on the reel unit 60. The success / failure lottery means 112 transmits the lottery result corresponding to the symbol variation to the symbol mode determining unit 131 and the effect determining unit 132 together with the symbol variation control command at the timing of starting the symbol variation.

  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. The symbol determination means 114 holds a symbol determination table to be referred to in order to determine a special symbol stop symbol. The symbol determination unit 114 acquires a symbol lottery value for determining a special symbol, and determines a stop symbol of the special symbol according to the determination result of the success / failure lottery unit 112 and the symbol lottery value.

  The symbol determination means 114 determines the stop symbol of the normal symbol to be displayed on the normal symbol display device 59 according to the result of the open lottery by the success / failure lottery means 112. The symbol determination means 114 determines the stop symbol of the normal symbol according to the result of the open lottery in order to display the result of the open lottery in the normal symbol display device 59 in the form of a normal symbol. When the determined stop symbol becomes a predetermined symbol, it is determined that the normal symbol is a hit, and after the change display of the normal symbol is stopped at the stop symbol, the opening / closing control means 124 expands the start port 62. The opening mechanism 63 is expanded for a predetermined time.

  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.

  FIG. 5 is a diagram schematically showing a symbol determination table. FIG. 5A is a table that is referred to when the determination result is a big hit, FIG. 5B is a table that is referred to when the result of determination is wrong, and FIG. This table is referred to when the determination result is a small hit. The symbol determination means 114 refers to the symbol determination table of this diagram in symbol determination. In each symbol determination table, the correspondence between the special symbol represented by the numbers “0” to “9” and the symbol “−” and the symbol lottery value is defined. Each type of special symbol is associated with the result of determining whether or not the big hit, small hit, or missed, the odd number corresponds to the big hit, the even number corresponds to the small hit, and the symbol “-” is out. Correspond.

  As shown in FIG. 5A, the special symbols “1”, “3”, “5”, “7”, and “9”, which are odd numbers among the special symbols “0” to “9”, are associated with the jackpot. . Among them, the special symbol “7” indicates a 15R jackpot with certainty and is associated with a symbol lottery value range “0 to 99”. The special symbol “3” indicates a 2R jackpot with certainty and is associated with a symbol lottery value range “100 to 149”. Special symbols “1”, “5”, and “9” indicate 15R big hits without any probability change, the special symbol “1” is associated with the symbol lottery value range “150 to 189”, and the special symbol “190 to 229”. “5” is associated with, and “230 to 255” is associated with the special symbol “9”.

  As shown in FIG. 5B, the special symbol “-” is associated with the entire range of symbol lottery values in the case where the determination result is wrong.

  As shown in FIG. 5C, the special symbols “0”, “2”, “4”, “6”, and “8” that are even numbers among the special symbols “0” to “9” are associated with the small hits. Yes. The special symbol “0” is associated with the symbol lottery value range “0 to 49”, and the special symbol “2” is associated with the symbol lottery value range “50 to 99”. The special symbol “4” is associated with the symbol lottery value range “100 to 149”, the special symbol “6” is associated with the symbol lottery value range “150 to 199”, and the special symbol “8” is the symbol lottery. Corresponding to the value range “200 to 255”.

  Returning to FIG. 3, the variation pattern determination unit 115 selects any variation pattern from a plurality of types of variation patterns according to the result of the success / failure lottery. The variation pattern determining means 115 holds a variation pattern table to be referred to in order to determine the variation pattern. The variation pattern determination unit 115 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 unit 115 stores a plurality of types of variation patterns. 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.

  FIG. 6 is a diagram schematically showing the variation pattern table. The variation pattern determining means 115 refers to the variation pattern table for removal shown in FIG. 6A when the result of the determination is wrong. When the determination result is a 15R jackpot, the fluctuation pattern table for 15R jackpot shown in FIG. 6B is referred to. When the determination result is 2R big hit or small hit, the 2R big hit and small hit variation pattern table shown in FIG. 6C is referred to.

  In FIG. 6A, the pattern lottery values 0 to 10 are associated with a super reach “super 1”, and the pattern lottery values 11 to 20 are associated with a super reach “super 2”. The pattern lottery values 21 to 255 are associated with any variation pattern of “normal 1”, “normal 2”, and “no reach”. As described above, when the result of the determination is wrong, any one of super reach, normal reach, and no reach may be selected. In the variation pattern table for detachment, when a variation pattern of “no reach” is selected, a different table is referred to so that a variation pattern having a shorter variation time than the normal state is selected in the short time state. Further, the deviation variation pattern table is defined so that the column to be referred to is different depending on the number of holdings, and details of the normal state will be described later with reference to FIG.

  In FIG. 6B, the super lot of “super 1” is associated with the pattern lottery values 0 to 120, and the super reach of “super 2” is associated with the pattern lottery values 121 to 240. The pattern lottery values 241 to 250 are associated with the reach of “normal 1”, and the pattern lottery values 251 to 255 are associated with the reach of “normal 2”. As described above, when the determination result is 15R big hit, the variation pattern with reach is selected.

  In FIG. 6C, the pattern lottery values 0 to 122 are associated with the super reach “super 3”, and the pattern lottery values 123 to 255 are associated with the normal reach “normal 3”. As described above, when the determination result is 2R big hit or small hit, “Super 3” or “Normal 3” is selected with a probability of about 50%.

  Returning to FIG. 3, the fluctuation pattern determination means 115 determines the fluctuation display time of the normal symbol. In the normal state, the variable display time is determined to be 60 seconds, and in the easy entry state, the variable display time is determined to be 6 seconds.

  When there is a new entry at the start port 62 and a new winning / failing lottery is executed, the holding control means 116 displays a new entry when a symbol change corresponding to the previous entry or lottery is displayed. The result of the success / failure lottery based on is suspended until the start of variable display of the symbol corresponding to the lottery. In the present embodiment, as a result of the lottery determination, the number of the lottery is held as a holding ball with an upper limit of four. The success / failure lottery value here includes a success / failure lottery value, a symbol lottery value, and a variation pattern lottery value. The holding control means 116 further holds the usual lottery value acquired by the success / failure lottery means 112 as a holding ball. These numbers of holdings are represented by the number of lighting or blinking numbers of the special symbol holding display device 20 and the normal symbol holding display device 22, respectively.

  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 variation display of the special symbol 192 according to the variation pattern determined by the variation pattern determination unit 115. The main display control means 118 sets a new symbol variation start condition that the symbol variation display corresponding to the success / failure lottery performed before that has ended. The main display control means 118 transmits a change start command and a change stop command to the effect display control means 134 at the timing for starting and stopping the change display of the special symbol 192. When the variation start command is transmitted, values indicating the determined determination result, the stop symbol, and the variation pattern are transmitted to the effect determination unit 132 and the effect display control unit 134 together with the variation start command. When transmitting the variation stop command, a value indicating the stop symbol is transmitted to the effect display control means 134 together with the variation stop command. Thereby, the fluctuation display by the main display control means 118 and the effect display control means 134 is synchronized, and the interlock is maintained. The main display control means 118 displays the result of the normal symbol lottery on the normal symbol display device 59 as a normal symbol variation display.

  The special game control means 120 indicates that the special game operation condition is established when the special symbol 192 is stopped in a predetermined big hit mode when the success / failure lottery by the success / failure lottery means 112 results in the transition to the special game. A special game is executed by determining and opening the special winning opening 66. 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. Special games include a 15R jackpot that repeats a unit game 15 times and a 2R jackpot that repeats a unit game that has a shorter opening time than the 15R jackpot only twice. In the case of 15R jackpot, in principle, the big winning opening 66 is opened for about 30 seconds in one unit game. In the case of 2R big hit, the big winning opening 66 is opened for about 0.5 seconds in one unit game. The special game control means 120 ends the special game when the set round number of unit games is exhausted. Even in the case of 2R big hit, if the predetermined condition is satisfied, the big winning opening 66 may be opened in the same manner as the 15R big hit.

  The specific game executing means 122 controls the normal game in the probability changing state, the short time state, and the easy-to-enter state. The specific game execution means 122 shifts the game state to the time-saving state and the easy-to-enter state after the end of the special game. On the other hand, the transition to the probability variation state after the end of the special game is limited to the case where the symbol determined by the symbol determination means 114 is a big hit symbol accompanied by the transition to probability variation. The short-time state and the easy-to-enter state are continued until the number of times of display of the special symbol 192 reaches a predetermined number of end conditions, for example, 100 times from the end of the special game. However, when the state changes to the probability changing state at the same time, as long as the probability changing state continues, the short time state and the easy entry state are continued. That is, it continues until the next big hit occurs.

  Thus, the end of the short time state and the easy entry state is determined according to the gaming state. In the short time state, the fluctuation pattern determining means 115 selects a fluctuation pattern having a short fluctuation time so that the fluctuation display time of the special symbol 192 is substantially shortened. However, in a normal state, a variation pattern table corresponding to the number of holds of the result of lottery determination by the hold control unit 116 is referred to, and a change pattern with a long variation time is likely to appear as the number of hold by the hold control unit 116 decreases. In the easy entry state, the normal symbol time is shortened, the normal symbol probability change, and the expansion mechanism 63 is opened and extended. On the other hand, the probability variation state is continued until a special game with the next jackpot is executed. During the probable change state, the probability that the success / failure determination result by the success / failure lottery means 112 is a big hit 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.

  The main state storage unit 126 functions as an “information storage unit” and stores a game state including a control state by the main board 102. Specifically, the results of the lottery results, the information on the determined variation pattern, the current gaming state, such as during symbol variation, during special games or during specific games (probability variation, during short time), and progress of symbol variation The fluctuation remaining time representing the information is stored in a predetermined area of the backup RAM described later. Even if the power is shut off during symbol changes due to an external factor or the like, necessary information is read from the backup RAM and transmitted to the sub-board 104 side when the power is turned on again.

  The initialization execution means 127 is used when a preset initialization condition is satisfied, such as when an external input is made via the RAM clear switch 92 or when an error occurs during the storage process by the main state storage means 126. Then, an initialization process for clearing data stored in the backup RAM is executed.

  The power interruption recovery control means 128 functions as “power interruption processing means”, “power interruption recovery means” and “power interruption recovery command transmission means”, and executes power interruption processing described later when the power is turned off. A power-on process described later is executed. The power supply unit 48 (see FIG. 3) is provided with voltage monitoring means, and when the supply voltage to the main board 102 falls below the reference voltage, an “interruption signal” indicating that is output to the main board 102. To do. When the power interruption return control means 128 receives this power interruption signal, the power interruption return control means 128 executes a power interruption processing described later for saving the gaming state. When the power is turned off and then turned on again, the power interruption return control means 128 executes a power-on process to be described later for starting the game control normally.

  The pattern storage unit 130 holds a plurality of variation effect patterns in which the display process of the symbol variation effect of the decorative symbol 190 by the reel unit 60 is defined. In the variation effect pattern, a variation process (that is, a variation process of a plurality of rows of reels) from the start to the end of variation of each symbol of the decorative symbol 190 including three columns of symbols is defined.

  The effect determination unit 132 selects a variation effect pattern corresponding to the variation pattern of the special symbol determined by the variation pattern determination unit 115 based on the result of the success / failure lottery received from the success / failure lottery unit 112. Then, the selected variation effect pattern is read from the pattern storage unit 130, and information on the variation effect pattern is sent to the effect display control unit 134. The effect determining means 132 holds a pattern table that should be referred to in order to select a variable effect pattern.

  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 means 132 selects a change effect pattern having the same change time according to the change pattern of the special symbol.

  The symbol form determining means 131 determines the combination of stop symbols of the decorative symbol 190 and their arrangement according to the result of the success / failure lottery by the success / failure lottery 112, depending on the special symbol stop symbol, the special symbol variation pattern, and the decorative symbol variation effect pattern. To decide. 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 determination table to be referred to in order to determine the stop symbol of the decorative symbol.

  The stop symbol of the decorative symbol 190 is formed as a combination of three symbols. In this embodiment, when the result of the success / failure determination by the success / failure lottery means 112 indicates a shift to a special game of 15R big hit, “111”, “222”, “333”, “444”, “555” and “666” ”Is selected, a specific combination in which three symbols arranged on the active line are selected. In this embodiment, if the result of the lottery determination is a big hit with a probability change (also referred to as “probable big hit”), any one of “111”, “333” and “555”, that is, three symbols are odd symbols. The combination that is aligned with is selected. On the other hand, if the winning / losing lottery result is a big hit (also referred to as “normal big hit”) without any change in probability, any one of “222”, “444” and “666”, that is, a combination of three symbols arranged in odd numbers. Is selected. When the determination result is 2R big hit or small hit, a predetermined combination in which the odd symbols or even symbols that are either “135” or “246” are arranged in ascending order from the left is selected. That is, the specific combination of 2R big hit and small hit in the present embodiment is not a combination of three symbols. When the determination result is neither big hit nor small hit, it is a combination in which three symbols such as “312” and “546” are not arranged, and a specific combination selected at the time of 2R big hit or small hit A combination that does not apply is selected. When the determination result is not 15R big hit, and a variation pattern indicating a loss with reach is selected, a combination having only one symbol such as “151” or “323” is selected. . The effect determining unit 132 sends the stop symbol combination of the decorative symbol 190 and the variation pattern data of the decorative symbol to the effect display control unit 134.

  The effect display control means 134 drives each reel of the reel unit 60 according to the selected variation effect pattern data as a result of the success / failure lottery by the success / failure lottery means 112, and variably displays the decorative symbols. The effect display control means 134 starts a new symbol variation when a variation start command for the decorative symbol 190 is received. When receiving the power interruption return command at the time of power recovery, the effect display control means 134 executes variable display control for stopping the decorative symbols in a specific symbol combination to be described later as a power interruption recovery process. The specific contents will be described in detail later. 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 position determination means 136 corresponds to the position of each reel in the rotation direction of the reel unit 60 when the power supply to the pachinko gaming machine 10 is restored from the cut-off state (the symbol located on the effective line indicating the result of the determination of success or failure). To determine). This is because the decorative symbol variation display after the power is restored is executed based on the position information. The position of each reel is determined by detecting any detection piece associated with each symbol in each reel by a position detection sensor provided in the main body of the reel unit 60. It will be described later.

  FIG. 7 is a diagram showing in detail a variation pattern table for detachment. In the variation pattern table 210 of this figure, the range of the pattern lottery value associated with the variation pattern is different for each number of holds. Specifically, the smaller the number of holds, the wider the range of pattern lottery values assigned to variation patterns with relatively long variation times, and the probability that variation patterns with long variation times will be selected is increased. . Therefore, the average fluctuation time becomes longer as the number of holdings by the holding control means 116 is smaller. Therefore, when the number of holds by the hold control means 116 is less than a predetermined number, for example, 1 to 2, the selection probability of the change pattern having a long change time becomes higher than usual, and the change time tends to be relatively long.

  The first column 212 shows the correspondence between the pattern lottery value range and the variation pattern when the number of holds as a result of the lottery determination by the hold control means 116 is one. Similarly, in the second column 214, the third column 216, and the fourth column 218, the correspondence between the pattern lottery value range and the variation pattern in the case where the number of holdings as a result of the lottery determination by the holding control means 116 is 2, 3, and 4, respectively. The relationship is shown. That is, it can be considered that the first column 212, the second column 214, the third column 216, and the fourth column 218 indicate the variation pattern table for each number of holds. In this figure, an example will be described in which a plurality of variation patterns that can be selected at the time of deviation are classified into five types according to variation time, but actually, a plurality of variation effect patterns are prepared for each of these classifications. This is equivalent to the fact that dozens of types of variation effect patterns are associated with the lottery value ranges for each category. In order to compare the ratio of each pattern lottery value range in the second column 214, the third column 216, and the fourth column 218 in this figure with the ratio of the pattern lottery value range in the first column 212, Broken lines indicating the ratio of the pattern lottery value range are drawn in the second column 214, the third column 216, and the fourth column 218.

  The first range 222 includes any of the first column 212, the second column 214, the third column 216, and the fourth column 218 as a variation pattern when the lottery value corresponds to a pattern lottery value from 0 to 10. A super reach variation pattern of “super 1” is associated. The second range 224 includes any of the first column 212, the second column 214, the third column 216, and the fourth column 218 as a variation pattern when the lottery value corresponds to a pattern lottery value from 11 to 20. A super reach variation pattern of “super 2” is associated. Thus, in the case of the pattern lottery value with the lottery value from 0 to 10 and the pattern lottery value with the lottery value from 11 to 20, the variation pattern having the same variation time is selected regardless of the number of holdings.

  The third range 226 includes normal reach in the first column 212, the second column 214, the third column 216, and the fourth column 218 as a variation pattern when the lottery value corresponds to a pattern lottery value from 21 to 255, respectively. “Normal 1”, “Normal 2”, and “Reach without reach” are associated with each other. However, the range of pattern lottery values associated with each variation pattern varies depending on the number of holds. In the first column 212, the sizes of the lottery value ranges to which “normal 1”, “normal 2”, and “no reach” are associated are approximately equal, and the ranges obtained by dividing 21 to 255 into approximately three equal portions are associated with each other. Yes. On the other hand, in the second column 214, the size of the lottery value range associated with “normal 1” and “normal 2” is smaller than the lottery value range associated with “no reach”. Further, in the third column 216 and the fourth column 218, the size of the lottery value range associated with each of “normal 1” and “normal 2” is further reduced.

  The fluctuation time of “Normal 1” and “Normal 2” may be longer than the fluctuation time of “Out of reach”, and in the case of “Out of reach”, the fluctuation time may be shortened like a short time state. Depending on the setting contents of the third range 226, the average variation time varies. The pattern lottery value range for “Normal 1” and “Normal 2” decreases as the number of holds increases from 0 to 1, 2, 3, 4, and conversely the pattern lottery value range for “out of reach” increases. Therefore, the average fluctuation time becomes shorter as the number of holds increases, and conversely, the average change time becomes longer as the number of holds decreases. In this way, by using a variation pattern table in which the correspondence between the pattern lottery value range and the variation pattern is different for each number of holdings, control that makes it easy to select a variation pattern with a long variation time when the number of holdings decreases is realized. be able to.

  The variation pattern of “out of reach” associated with the third column 216 has a shorter variation time than the “out of reach” associated with the first column 212 and the second column 214, so-called “shortening variation”. This is the fluctuation pattern. Further, the fluctuation pattern of “out of reach” associated with the fourth column 218 has a shorter variation time than the “out of reach” associated with the first column 212 and the second column 214, and the third column This is a fluctuation pattern of so-called “super-shortening fluctuation” in which the fluctuation time is shorter than “216 shortening fluctuation”.

  Here, an outline of the power failure recovery method in this embodiment will be described. That is, for example, when the power supply to the game control device 100 is interrupted due to an external factor such as a power failure during the symbol variation, the symbol variation is forced to be interrupted. On the other hand, even if the power supply to the reel unit 60 is stopped due to the power interruption, the reel 206 may continue to rotate due to its inertia. In particular, in this embodiment, the game control state at the time of power-off is not backed up on the sub-board 104 side. As a result, information such as the variation remaining time of the symbol variation in accordance with the variation pattern, the stop symbol of the decorative symbol 190, etc. becomes unclear. In the present embodiment, even in such a case, when the power is restored, the interruption-on process is executed so that the rest of the suspended symbol variation can be smoothly resumed.

  That is, a processing unit that operates by receiving power supply from the power supply unit 48 is mounted on the main board 102. This processing unit includes a CPU that executes arithmetic processing, a ROM that stores a game program, a volatile processing RAM that functions as a work area for executing the game program, and a non-volatile backup that backs up game data. RAM etc. are provided. In addition to the game program, the ROM stores a parameter group indicating the initial state of the game program (hereinafter simply referred to as “initial state data”). When the power is cut off, the CPU stops its operation and the data on the processing RAM is lost, but the game data stored in the backup RAM is retained. The “game data” here is data including initial state data and midway state data to be described later, and all or a part of the data is subject to backup.

  The backup RAM holds midway state data. The “intermediate state data” here is game data indicating the game state at the time of the previous power-off. When the power is turned on, the CPU loads the game program from the ROM to the processing RAM. When there is no appropriate halfway state data in the backup RAM, the game is started from the initial state by loading the initial state data into the processing RAM and executing the game program based on the initial state data. On the other hand, if the intermediate state data is properly backed up in the backup RAM, the CPU loads the intermediate state data into the processing RAM instead of the initial state data, and based on the intermediate state data loaded into the processing RAM. To execute the game program. This makes it possible to reproduce the gaming state that was interrupted when the power was turned off.

  When the power supply is cut off, the supply voltage from the power supply unit 48 to the processing unit gradually decreases. The voltage monitoring means of the power supply unit 48 transmits an interruption signal to the processing unit of the main board 102 when the supply voltage falls below a predetermined interruption determination value. When the power interruption return control means 128 receives the power interruption signal, it executes a power interruption processing for saving specific game data. That is, all or a part of the game data on the processing RAM, the winning / failing lottery results, the determined variation pattern, and the game state such as presence / absence of symbol variation are saved to the backup RAM by the power interruption process. The During the power interruption process, the normal game process sleeps. When the supply voltage falls below the minimum voltage at which the CPU can operate, the CPU stops. Therefore, the CPU completes the power interruption process before the supply voltage falls below a predetermined power interruption determination value and further below the minimum voltage.

  On the other hand, a processing unit that operates by receiving power supply from the power supply unit 48 is also mounted on the sub-board 104. This processing unit also includes a CPU, a ROM, a processing RAM, and the like. The ROM stores game programs such as production control. The function of the pattern storage means 130 of the sub-board 104 is mainly realized by a ROM, and information such as a flag used in the processing process is stored in the processing RAM. Each function of other means of the sub-board 104 is realized mainly by a game program executed by the CPU. However, since the sub-board 104 of this embodiment does not have a backup function, the CPU stops operating when the power is cut off, and the data on the processing RAM is lost.

  When the power is turned on, the CPU loads the game program from the ROM to the processing RAM and executes the game program. Regarding the decorative symbol variation processing, the position information of each reel (that is, symbol information located on the effective line) sequentially determined by the position determining means 136 is stored in the processing RAM. If the power supply is interrupted due to an external factor such as a power failure during symbol variation, the decorative symbol variation display is forced to be interrupted, and the position information data on the processing RAM is also lost. In this embodiment, even in such a case, a power-on process described later is executed so that the suspended decorative pattern change display can be quickly resumed when the power is restored.

  Next, a specific configuration for detecting the position of each reel of the reel unit 60 and its position detection method will be described. 8-10 is explanatory drawing showing the structure of a reel unit. In each figure, the reel unit 60 extracted from the game board 50 is shown for convenience. FIG. 8A is a perspective view of the reel unit 60, and FIG. 8B is a perspective view of a reel device that constitutes the reel unit 60. FIG. 9 is an exploded perspective view of the reel device. FIG. 10A is a front view of the reel device, and FIG. 10B is a side view of only the detected member 231 shown in FIG. 10A.

  As shown in FIG. 8A, the reel unit 60 is configured to accommodate a left reel device 201, a middle reel device 203, and a right reel device 205 in a rectangular case 200. Each reel device includes an individual reel and an actuator such as a motor for driving the reel. The case 200 contains an actuator for individually rotating each reel, and a sensor for detecting the position of each reel in the rotational direction. The drive current is supplied to the actuator, and the output of the sensor. A harness (not shown) for taking out a signal is drawn out to the outside. The harness is connected to the sub board 104 and the power supply unit 48.

  That is, the left reel device 201 includes a left reel 206a on which a left symbol 191 is disposed, the middle reel device 203 includes a middle reel 206b on which a middle symbol 193 is disposed, and the right reel device 205 includes a right symbol 195. It includes a right reel 206c provided. The three reels of the left reel 206a, the middle reel 206b, and the right reel 206c are arranged side by side in the case 200, and a part of the reels is supported so as to be exposed from the opening 211 on the front side of the case 200. . That is, each reel is arranged so that a part of its peripheral surface can be presented to the player. In the following description, when the left reel 206a, the middle reel 206b, and the right reel 206c are not particularly distinguished, they are collectively referred to as “reel 206” as appropriate.

  As shown in FIG. 8B, in each reel device (left reel device 201, middle reel device 203, and right reel device 205), a reel 206 is rotatably supported on a rotation shaft of a motor fixed to a base member 213. It is configured as described. Then, by fixing the base member 213 to the case 200, the left reel 206a, the middle reel 206b, and the right reel 206c are supported by the case 200 so that the rotation axes thereof are arranged on the same axis. Each reel device includes a position detection sensor 215 for detecting the position of each reel in the rotation direction.

  As shown in FIG. 9, the base member 213 is provided with a motor 217, a backlight 219, and a position detection sensor 215. The motor 217 is composed of a stepping motor, and is driven forward or backward by switching its energization direction. The backlight 219 has a main body with an arc-shaped cross section, and is configured to be lit or blinking in a plurality of colors when energized. The backlight 219 is disposed on the inner side of the reel 206, and is lit or blinked when a specific effect is performed to illuminate the reel 206 from the inner side. The position detection sensor 215 detects a detection piece, which will be described later, fixed to the reel 206. As will be described later, by detecting a plurality of detection pieces provided on the reel 206, it is possible to detect the position of the reel 206 in the rotational direction, and thus the symbol presented to the player.

  The reel 206 has a cylindrical reel body 207 having translucency, and is formed by being stuck so as to wind a reel tape 208 along the outer peripheral surface of the reel body 207. As will be described later, a plurality of symbols (numerical symbols “1” to “6” and six blank symbols “*”) are printed on the reel tape 208 along the longitudinal direction. The plurality of symbols are printed at equal intervals (every 30 degrees) along the outer peripheral surface of the reel body 207. The reel 206 is provided with a cross-shaped beam 220 so as to bridge one opening in the diametrical direction, and a cylindrical shaft 221 is formed at the center of the beam 220. The reel 206 is rotatably supported by the motor 217 by fixing the cylindrical shaft 221 to the rotation shaft of the motor 217. The reel 206 is disposed so as to surround the motor 217 and the backlight 219. Since the reel body 207 has translucency, the lighting or blinking mode of the backlight 219 is provided in a form that decorates the reel 206.

  Three detected members 231, 232, and 233 are attached to the reel 206. Each detected member is formed by processing a plate-like member into a cross shape. The detected member is provided with arms 234 extending radially outward from the center thereof every 90 degrees, and a detection piece 235 is projected on one side surface of the tip of each arm 234. That is, each detection member is provided with four detection pieces 235, and the detection member 231, the detection member 232, and the detection member 233 are assembled to the reel body 207 in this order.

  As shown in FIG. 10A, the detected member 231 is assembled to the reel body 207 along the beam 220. The four detection pieces 235 of the member to be detected 231 extend to the position detection sensor 215 side through insertion holes that penetrate the beam 220 in the thickness direction. The detected member 232 is attached so as to be shifted by 30 degrees with respect to the detected member 231, and the detected member 233 is attached so as to be further shifted by 30 degrees with respect to the detected member 232. As a result, as shown in the figure, twelve detection pieces 235 provided on the three detected members 231, 232, 233 are arranged at equal intervals (every 30 degrees) along the circumference where the position detection sensor 215 is located. Be placed.

  As shown in FIG. 10B, the position detection sensor 215 includes a transmissive photosensor having a light emitting portion and a light receiving portion, and each detection piece 235 is positioned between the light emitting portion and the light receiving portion to receive light. When the light reception by the unit is interrupted, the corresponding detection piece 235 is detected. Since the twelve detection pieces 235 have shapes with different light shielding positions, the effect display control means 134 can determine which detection piece 235 is detected, that is, the position in the rotation direction of the reel 206. On the other hand, since the positional relationship is set such that one of the symbols is positioned on an effective line, which will be described later, when each detection piece is detected, the effect display control means 134 uses the detection information of the position detection sensor 215. It can be determined which symbol arranged on the reel 206 is located on the effective line. In the modified example, the widths of the twelve detection pieces 235 are made different so that the respective light shielding times with respect to the rotation speed of the motor 217 are different, and which detection piece 235 is detected based on the light shielding time, and thus You may make it determine which symbol was located on the effective line.

  FIG. 11 is a schematic diagram illustrating a detection method using a position detection sensor. (A)-(c) is explanatory drawing which shows the specific example of the detection method by the position detection sensor 215, respectively. That is, in this embodiment, as shown in FIG. 11 (a), the symbol of symbol number 1 for detecting that the symbol of symbol number 1 has reached the first effective line L1 is the symbol of symbol number 12 is the first effective line. A total of twelve detection pieces 235 of detection pieces 235 for detecting the arrival at L1 are provided, and the length of each detection piece (the length of the portion that blocks light from the light emitting portion: “light shielding length”). Is also different). As illustrated, the position detection sensor 215 includes 12 light emitting elements and 12 light receiving elements corresponding thereto. Since light is emitted from each light emitting element toward the opposite light receiving element, the light receiving element can receive the light unless the light is blocked. For this reason, for example, when the detection piece corresponding to the symbol of symbol number 1 is positioned on the first effective line L1, the light from one light emitting element is shielded, and the detection piece corresponding to the symbol of symbol number 3 is the first effective line. When positioned at L1, light from the three light emitting elements is shielded. The effect display control means 134 determines which symbol is positioned on the effective line by determining the light shielding state (or the light receiving state) when the detection piece 235 reaches the effective line from the detection state of the light receiving element. can do.

  In the modification, a different detection method may be employed. For example, as shown in FIG. 11B, through holes are provided in different modes in the length direction of each detection piece so that the light-shielding modes (combination of light-shielding positions: also referred to as “light-shielding pattern”) by each detection piece are different. May be. In the illustrated example, the position detection sensor 215 includes four light emitting elements and four corresponding light receiving elements. The through hole in each detection piece is provided in accordance with any of a plurality of optical paths connecting the light emitting element and the light receiving element. For this reason, for example, when the detection piece corresponding to the symbol of symbol number 1 is positioned on the first effective line L1, all the light from the four light emitting elements is detected on the light receiving element side. Further, when the detection piece corresponding to the symbol of symbol number 3 is positioned on the first effective line L1, light from the three light emitting elements is received (light at a specific one position is blocked). The effect display control means 134 determines which pattern is located on the effective line by determining the pattern of the light shielding position (or the light receiving position) when the detection piece 235 reaches the effective line from the detection state of the light receiving element. Can be determined.

  Or as shown in FIG.11 (c), what has a different transmittance | permeability of light may be used as each detection piece, and the transmittance | permeability by each detection piece may differ. Even in this way, the effect display control means 134 determines which pattern is effective by determining the transmittance (the amount of transmitted light or the intensity of light) when any of the detection pieces 235 reaches the effective line. It can be determined whether it is located on the line.

  FIG. 12 is an explanatory diagram showing the correspondence between the symbol arrangement and symbol number in each reel. The effect determining means 132 manages the design of each reel with the design number, and specifies the stop design of the decorative design 190 by the combination of the design number. In the present embodiment, symbol numbers “1” to “12” are set. When the reel 206 is rotated forward in normal symbol variation control, symbols are displayed on the active line in the order of symbol numbers “1” to “12” (see arrows in the diagram).

  As shown in the figure, for the left symbol 191, a numeric symbol “1” is assigned to the symbol number “1”, a blank symbol “*” is assigned to the symbol number “2”, and a numeric symbol “3” is assigned to the symbol number “3”. 2 ”, and so on. That is, in the left symbol 191, numeric symbols are associated with symbol numbers in ascending order, and blank symbols are set between the numeric symbols as described above. For the middle symbol 193, a blank symbol “*” for symbol number “1”, a numeric symbol “4” for symbol number “2”, a blank symbol “*” for symbol number “3”,.・ It is associated with such a condition. That is, the middle symbol 193 is also associated with the symbol numbers in ascending order, and a blank symbol is set between each numeric symbol, but the correspondence relationship is different from that of the left symbol 191. For the right symbol 195, the symbol number “1” is the numeric symbol “6”, the symbol number “2” is the blank symbol “*”, the symbol number “3” is the numeric symbol “5”,.・ It is associated with such a condition. That is, in the right symbol 195, numeric symbols are associated with symbol numbers in descending order, and a blank symbol is set between each numeric symbol. The left symbol 191 and the middle symbol 193 are arranged in ascending order as described above, while the right symbol 195 is arranged in descending order in order to form a plurality of effective lines (form a multiline). It is.

  FIG. 13 is a diagram schematically showing a return symbol determination table that is referred to when determining a decorative symbol at the time of power recovery. However, for convenience of explanation, a part of the return symbol determination table is shown in FIG. Moreover, the example of the decoration symbol (display of the symbol shown to a player) for showing the structure method of a table is shown in the margin of a table.

  Even if the progress of a game is interrupted in the middle of a symbol change due to an unexpected power interruption such as a power failure or the like, the symbol mode determining means 131 can have the remaining time of the symbol change in order to smoothly restart the symbol change when the power is restored. The stop symbol at the time of power recovery is determined so that at least the decorative symbol can be stopped at the determined stop symbol. That is, the symbol form determination means 131 acquires position information of three columns of symbols (left symbol 191, middle symbol 193, right symbol 195) when power is restored, and promptly determines a stop symbol combination (stop symbol pattern). Specifically, the shortest stop symbol pattern that can stop the specific symbol combination that is not the winning symbol combination substantially in the shortest time is determined as the stop symbol pattern at the time of power recovery, and the information is sent to the effect display control means 134. send. The effect display control means 134 drives each reel of the reel unit 60 so as to stop the three rows of symbols at the shortest stop symbol pattern.

  Therefore, in the illustrated return symbol determination table, a plurality of stop symbol patterns constituting a specific symbol combination that is not a winning symbol combination are defined. In addition, as the “specific symbol combination” here, in addition to an out symbol combination indicating that the result of the lottery decision is out of place, a symbol including a blank symbol that does not become a part of the stop symbol combination indicating the result of the lottery decision A combination is defined. Note that symbol combinations indicating 2R big hit and small hit are also excluded from the specific symbol combinations. That is, as described above, the number symbol “1” to “6” and the blank symbol “*” are provided as the stop symbol candidates of the left symbol 191, the middle symbol 193, and the right symbol 195. A symbol combination that indicates a big hit and a symbol combination that indicates a small hit are excluded as a specific symbol combination. In the present embodiment, as described above, “135” and “246” are set as symbol combinations indicating 2R big hit or small hit, so these symbol combinations are excluded. In the present embodiment, the 2R big hit and the small hit are controlled so as to be displayed only on the central horizontal line (the effective line L1 in FIG. 14). In a modified example, it may be displayed on the upper and lower horizontal lines (effective lines L2, L3) and diagonal lines (L4, L5). In that case, the return symbol determination table is configured so as to exclude symbol combinations indicating 2R big hits and small hits in each active line.

  That is, as shown in the figure, symbol combinations such as “1 * 6”, “1 **”,... Are set as selection targets as specific symbol combinations whose left symbol 191 is “1”. However, since the symbol mode determining unit 131 manages the symbol combination as a symbol number combination, for example, the decorative symbol “1 * 6” is managed as the symbol number (1, 1, 1). As shown in the figure, for the decorative symbol “1 * 6”, neither big hit nor small hit is shown for any effective line. Further, as can be seen from the portion indicated by a thick frame in the figure, “111” indicating the big hit, “135” indicating the 2R big hit or the small hit, etc. are excluded from the specific symbol combination. That is, the symbol number (1, 8, 11) corresponding to the decorative symbol “111” and the symbol number (1, 12, 3) corresponding to the decorative symbol “135” are excluded (see “X” in the diagram). ). The symbol mode determining means 131 acquires symbol information located on or near the active line at the time of power recovery and then refers to the illustrated symbol determination table shown in FIG. The design pattern is determined.

  FIG. 14 is an explanatory diagram showing a decorative pattern variation control method when power is restored. FIGS. 9A to 9D show an example of the process of changing the decorative pattern. FIG. 15 is a timing chart illustrating the decorative pattern variation control when the power is restored. In the figure, from the upper stage, the fluctuation state of the left reel 206a (left symbol 191), the operating state of the motor driving the left reel 206a, the fluctuation state of the middle reel 206b (middle symbol 193), the operation of the motor driving the middle reel 206b. The state, the fluctuation state of the right reel 206c (right symbol 195), and the operation state of the motor that drives the right reel 206c are shown. The horizontal axis of the figure shows the passage of time.

  As shown in FIG. 14A, in the reel unit 60, the left symbol 206a, the middle reel 206b, and the right reel 206c are individually driven to rotate, whereby the left symbol 191, the middle symbol 193, and the right symbol 195 are displayed in a variable manner. Is done. In the figure, the symbol fluctuation state at the time of power recovery is shown, and an example in which symbols in a plurality of rows rotate in the opposite direction (upward direction) to the symbol fluctuation at the normal time is shown. In the modified example, when the power is restored, it may be rotated in the forward direction (downward) as in the normal state. In the symbol row of each reel, three symbols can be displayed in the upper, middle, and lower rows, and as shown in the figure, a line (effective line) that can display the result of winning / failing lottery by combining the three rows of symbols. Are formed. That is, the first effective line L1 that is the middle horizontal line, the second effective line L2 that is the upper horizontal line, the third effective line L3 that is the lower horizontal line, the fourth effective line L4 that is the diagonal line, and the fifth An effective line L5 is formed. For this reason, even if the winning symbol combination is displayed on any effective line, the big hit is shown. However, when a blank symbol “*” is displayed on the active line, the active line does not function as a line indicating the result of the lottery. That is, as described above, the blank symbol “*” functions as a symbol that limits the effective line.

  By the way, if a winning symbol combination is displayed after the power is restored even though the result of lottery determination that has been determined before the power is turned off and the fluctuation display is started is incorrect, the adjustment is made so that the symbol combination is finally lost. It can be said that it is sufficient to change. However, once the winning symbol combination is displayed, the result of losing is also disappointing for the player who has recognized the big hit, which is not preferable in terms of improving the operating rate of the gaming machine. On the other hand, in the present embodiment, as described above, the symbol fluctuation control state at the time of power shut-off is not backed up on the sub board 104 side. In addition, in this embodiment, the information on the result of the lottery determination is not accompanied by the power interruption return command, but is sent along with the change stop command transmitted thereafter. For this reason, the display state of the decorative symbol at the time of power recovery is unknown. Therefore, in this embodiment, the first effective line L1 is used as a reference, and the symbol that reaches the first effective line L1 in the shortest time is detected in each symbol row when power is restored, and is displayed on the first effective line L1. Know the symbol number of the symbol. Then, control is performed so that the specific symbol combination that does not show either the big hit or the small hit on the first effective line L1 can be quickly stopped. If the result of the lottery is wrong, the specific symbol combination may be stopped as it is, and if it is a big hit or a small hit, the stopped symbol combination may be changed by a subsequent adjustment change.

  In this embodiment, in the variation control of the decorative symbol when the power is restored, the left symbol 191, the middle symbol 193, and the right symbol 195 start rotating in this order, and the left symbol 191 and the middle symbol sequentially positioned on the first effective line L 1. In accordance with 193, the shortest stop symbol pattern to be a specific symbol combination is determined. In the present embodiment, the left symbol 191 corresponds to the “reference symbol”. Then, the right / left lottery result is displayed by stopping the right symbol 195 in accordance with the stop timing of the special symbol 192. That is, when returning from the power-off state and receiving a power-off return command from the main board 102 (time t1), first, the left reel 206a is driven as shown in the upper part of FIG. 14 (a) and FIG. Then, when the left symbol 191 located on the first effective line L1 is detected in the shortest time, the left symbol 191 is stopped as shown in FIG. 14 (b) (in this embodiment, the slight fluctuation on the effective line) A pseudo stop state that fluctuates). At this time, the symbol form determining means 131 identifies the symbol number of the left symbol 191 located on the first effective line L1.

  Subsequently, as shown in the middle part of FIG. 14B and FIG. 15, the middle reel 206b is driven. When the middle symbol 193 positioned on the first effective line L1 in the shortest is detected, the middle symbol 193 is stopped as shown in FIG. 14 (c) (in this embodiment, the slight fluctuation on the effective line). A pseudo stop state that fluctuates). At this time, the symbol form determining means 131 specifies the symbol number of the middle symbol 193 located on the first effective line L1. Then, referring to the return symbol determination table of FIG. 13 using the combination of the symbol numbers of the left symbol 191 and the middle symbol 193 identified at this stage, the shortest stop that can stop the specific symbol combination including the right symbol 195 in the shortest time. Select a design pattern. In the illustrated example, since the symbol combination of the left symbol 191 and the middle symbol 193 is “11”, the symbol pattern determining means 131 has “*” that can be stopped in the shortest except “1” as the right symbol 195. The stop symbol pattern (1, 8, 12) is determined so as to be selected.

  Subsequently, as shown in the lower part of FIG. 14C and FIG. 15, the right reel 206c is driven. Then, when it is detected that “*” following the stop symbol pattern (1, 8, 12) is located on the first effective line L1 as the right symbol 195, as shown in FIG. 195 is stopped (in the present embodiment, a pseudo stop state in which a slight fluctuation is changed on the effective line). When the effect display control means 134 receives the change stop command from the main board 102, the effect display control means 134 definitely stops the three rows of symbols (time t2).

  Next, a characteristic configuration and control contents in the present embodiment will be described. In the present embodiment, as described above, the decorative symbol 190 is variably displayed in accordance with the fluctuating effect pattern, and the symbol variation is performed in order to stop the three columns of symbols (left symbol 191, middle symbol 193, right symbol 195) sequentially. In the process, correction variation for position correction is performed. Then, a method for determining the correction fluctuation pattern is devised so that the correction fluctuation does not become one pattern. Hereinafter, a configuration and a control method therefor will be described.

  FIG. 16 is a diagram schematically illustrating a correction table according to the first embodiment. The effect determining means 132 refers to the basic correction table shown in FIG. 16 (a) and the lottery correction table shown in FIG. 16 (b) when determining the correction fluctuation pattern that determines the fluctuation process of the correction fluctuation. The numbers in the figure indicate the number of driving steps of the motor 217. In this embodiment, when each reel (left reel 206a, middle reel 206b, right reel 206c) is rotated in one direction, it is set to make one rotation in 504 steps. Therefore, the amount of rotation for rotating each reel by one symbol including a blank symbol is 42 steps.

  That is, in order to stop the stop symbol combination of the decorative symbol 190 determined by the symbol pattern determining means 131 on the active line when the variation stop command is received, the variation of the three columns of symbols in the correction period during the symbol variation. Correction fluctuation for adjusting the speed and the fluctuation amount is executed. This correction variation is started at a correction start timing set in advance for each variation effect pattern, and is completed before the symbol variation related to the variation effect pattern is stopped. The effect determining means 132 determines a correction variation pattern with reference to the illustrated correction table in order to incorporate the correction variation into the symbol variation according to the variation effect pattern. The correction variation pattern defines the reel rotation speed and the rotation amount at each rotation speed that are changed stepwise during the correction period. In this embodiment, a plurality of types of correction correction patterns are provided for each of the basic correction table and the lottery correction table. A correction variation pattern is provided. The correction variation pattern of the present embodiment is set so that the symbol variation speed changes in three stages during the correction period.

  When determining the correction variation pattern, the effect determining unit 132 follows the stop symbol combination of the decorative symbol 190 determined by the symbol pattern determining unit 131, and the three columns of symbols (left symbol 191, middle symbol 193, right symbol 195). For each, a stop symbol (also referred to as “scheduled stop symbol”) constituting the stop symbol combination is specified. Then, for each of the three rows of symbols, the symbol number of the symbol to be stopped and the symbol number of the symbol currently displayed on the effective line (reference position) at the start of the correction variation are displayed on the effective line during the correction period. The number of symbols at the time of correction, which is the number of power symbols, is calculated.

  Subsequently, a variable correction variation pattern is determined by pattern lottery using the lottery correction table, and the number of symbols in the lottery progress is determined as a symbol number difference adjusted by the variable correction variation pattern. Subsequently, the difference in the number of symbols between the number of symbols at the time of correction and the number of symbols in the lottery is determined as the number of symbols to be corrected, which is the difference in the number of symbols to be adjusted according to the basic correction variation pattern. The basic correction variation pattern is determined with reference to the reference. Then, the rotation amount obtained by adding the rotation amount at each stage in the determined basic correction fluctuation pattern and the rotation amount at each stage in the determined variable correction fluctuation pattern is corrected at each stage of the correction period. The amount of rotation. That is, the rotation amount obtained by adding the rotation amount at each rotation speed in the determined basic correction variation pattern and the rotation amount at each rotation speed in the determined variable correction variation pattern is corrected at each rotation speed. A correction variation pattern as a rotation amount is determined. Note that in actual symbol fluctuations, a series of normal fluctuation control for one reel is performed by combining a constant speed fluctuation time after correction for changing the constant speed after the correction control and a deceleration fluctuation time for stopping from the constant speed fluctuation. Is realized.

  As shown in FIG. 16A, in the basic correction table, the basic correction variation patterns PT1 to PT12 are associated with the numbers of correction symbols “0” to “11”. Here, the “number of corrected symbols” means the difference in the number of symbols between the symbol positioned on the effective line at the start of the correction variation and the symbol to be stopped on the effective line. Therefore, the minimum symbol number difference is “0”, and the maximum symbol number difference is “11”. Specifically, as shown in the figure, for each basic correction variation pattern, the first stage rotational speed is set to a speed requiring 1.28 (ms) per step, and the second stage rotational speed is one step. The rotation speed is set to a speed that requires 1.92 (ms), and the rotation speed in the third stage is set to a speed that requires 2.56 (ms) per step. In other words, the rotation speed of the reel, that is, the symbol fluctuation speed is reduced at each stage. For example, the basic correction variation pattern PT1 corresponding to the correction symbol number “0” is determined so that the first stage is 27 steps, the second stage is 24 steps, and the third stage is 453 steps. The basic correction variation pattern PT12 corresponding to the correction symbol number “11” is determined such that the first stage is 962 steps, the second stage is 2 steps, and the third stage is 2 steps. As a tendency, the larger the number of corrected symbols, the longer the stay time in the first stage, and the shorter the stay time in the second stage and the third stage. In other words, the higher the number of correction symbols, the longer the time for high speed rotation and the shorter the time for low speed rotation.

  On the other hand, as shown in FIG. 16B, in the lottery correction table, variable correction variation patterns PT13 to PT20 are associated with the number of correction symbols “4” to “11”. However, the variable correction variation patterns PT13 to PT20 are not determined according to the number of correction symbols, but are determined by pattern lottery described later. Therefore, to be exact, the correction symbol numbers “4” to “11” are associated with the variable correction fluctuation patterns PT13 to PT20. As shown in the figure, for the variable correction fluctuation pattern, similarly to the basic correction fluctuation pattern, the first stage rotational speed is set to a speed requiring 1.28 (ms) per step, and the second stage rotational speed is set to 1. The speed that requires 1.92 (ms) per step is set, and the rotation speed in the third stage is set to a speed that requires 2.56 (ms) per step. In other words, the variable correction fluctuation pattern of the lottery correction table is set so that the number of stages at which the reel rotation speed changes during the correction period and the rotation speed at each stage are equal to the basic correction fluctuation pattern of the basic correction table. In this embodiment, as will be described later, since the process of adding the basic correction variation pattern and the variable correction variation pattern at each stage is executed, the rotational speeds at the respective stages of both correction variation patterns are matched. However, in the lottery correction table of this embodiment, eight types of correction symbols of 4 to 11 are set, and in any case, each time step is set when a single lottery progress symbol correction is performed. The number of movements can be set to a positive value. This is because a special adjustment process is required if the step operation needs to be negative. In other words, in this embodiment, the number of corrected progress symbols is set in a range in which the number of steps corresponding to the speeds of a plurality of stages used in the fixed time processing of the number of lottery progress symbols is a positive value. It should be noted that by setting the correction time to a long time, it is of course possible to increase the number of lottery correction symbols by keeping the calculation itself positive, and by doing so, correction with higher variety can be performed. In this embodiment, the number of lottery progression symbols is set so that the number of operations at each speed step is a positive value. However, as in this embodiment, the basic correction variation and the variable correction variation are collectively calculated. In the case of generating and performing a series of processing, the same processing can be realized without anomalous processing if the sum is set to be a positive value (including zero).

  FIG. 17 is a diagram schematically showing a pattern lottery table. The effect determination means 132 refers to the illustrated pattern lottery table when determining the variable correction variation pattern. In this pattern lottery table, the pattern lottery values “0 to 255” are assigned almost evenly to the variable correction variation patterns PT13 to PT20 described above. The effect determination means 132 determines a variable correction variation pattern by pattern lottery using the pattern lottery table, and refers to the lottery correction table of FIG. 16B using the variable correction variation pattern. Then, the number of lottery progress symbols corresponding to the variable correction variation pattern is specified, and the difference in the number of symbols between the number of symbols in progress and the number of symbols in the lottery progress is calculated as the number of corrected symbols. Subsequently, the basic correction variation pattern is determined by referring to the basic correction table of FIG. The number of steps of the basic correction variation pattern and the variable correction variation pattern determined in this way is added for each stage, and the number of steps after the addition is assigned to each stage is determined as the actual correction variation pattern.

  FIG. 18 is a diagram specifically illustrating a method for determining a correction variation pattern. In the drawing, the processing related to the above-described constant speed fluctuation and deceleration fluctuation is omitted, but in the constant speed fluctuation, fluctuation due to a step operation of 2.56 (ms) is performed. FIG. 18A shows a case where the number of symbols at the time of correction is 6 symbols and the variable correction variation pattern PT13 is selected by pattern lottery. FIG. 18B shows a case where the number of symbols at the time of correction is 6 symbols, and the variable correction variation pattern PT16 is selected by pattern lottery. FIG. 18C shows a case where the number of symbols at the time of correction is 8 symbols and the variable correction variation pattern PT15 is selected by pattern lottery. In the following description, the correction variation pattern determination method will be described by taking the left symbol 191 as an example, but the same determination method is also applied to the middle symbol 193 and the right symbol 195. Note that this correction control can be performed only on some reels.

  For example, the decorative symbol 190 indicating the result of the lottery determination is determined, the symbol to be stopped as the left symbol 191 is “1” of symbol number 1, and the left symbol 191 displayed on the active line at the start of the correction variation is the symbol When the number is “4”, the number of symbols at the time of correction is 6 symbols (see FIG. 12). At this time, if the variable correction variation pattern PT13 is selected by pattern lottery, the number of lottery progression symbols is 4 symbols from the lottery correction table of FIG. Therefore, the number of correction symbols to be adjusted by the basic correction variation pattern is 6 symbols-4 symbols = 2 symbols, and the basic correction variation pattern PT3 corresponding to the two symbols is selected from the basic correction table of FIG.

  That is, as shown in FIG. 18A, a combination of the basic correction fluctuation pattern PT3 and the variable correction fluctuation pattern PT13 is determined. Therefore, the correction variation pattern in this case is obtained by adding the rotation amount obtained by adding the rotation amount at each step in the basic correction variation pattern PT3 and the rotation amount at each step in the variable correction variation pattern PT13 to each step. This is the corrected rotation amount at. That is, the left reel 206a is rotated 279 steps at a rotational speed that requires 1.28 (ms) per step in the first stage of correction fluctuation, and at a rotational speed that requires 1.92 (ms) per step in the second stage. A correction variation pattern that is rotated 610 steps and rotated 371 steps at a rotation speed that requires 2.56 (ms) per step is determined in the third stage. At this time, the correction operation time of the left reel 206a in each stage is as shown in the figure, and the total operation time is 2478.08 (ms).

  Similarly, the decorative symbol 190 indicating the result of the lottery determination is determined, and the symbol to be stopped as the left symbol 191 becomes “1” of symbol number 1, and the left symbol 191 displayed on the active line at the start of the correction variation. Even if the symbol number is “4”, if the variable correction fluctuation pattern is different, the correction fluctuation pattern is also different. For example, when the variable correction variation pattern PT16 is selected by pattern lottery, the number of lottery progression symbols is 7 symbols from the lottery correction table of FIG. Therefore, since the number of correction symbols to be adjusted by the basic correction variation pattern is 6 symbols-7 symbols = −1 symbols, the total number of symbols of 12 symbols is added to adjust the difference in the number of symbols, and −1 symbol + 12 The symbol is 11 symbols, and the basic correction variation pattern PT12 corresponding to the 11 symbols is selected from the basic correction table of FIG. Here, since there is no pattern in which the number of correction symbols is negative as the basic correction variation pattern, adjustment is performed by adding the total number of symbols. However, in the modification, the number of correction symbols is negative as the basic correction variation pattern. A pattern may be further provided, and a basic correction variation pattern in which the number of correction symbols is -1 symbol may be selected.

  That is, as shown in FIG. 18B, a combination of the basic correction fluctuation pattern PT12 and the variable correction fluctuation pattern PT16 is determined. Therefore, the correction variation pattern in this case is obtained by adding the rotation amount obtained by adding the rotation amount at each step in the basic correction variation pattern PT12 and the rotation amount at each step in the variable correction variation pattern PT16 to each step. This is the corrected rotation amount at. That is, the left reel 206a is rotated 1422 steps at a rotation speed that requires 1.28 (ms) per step in the first stage of correction fluctuation, and at a rotation speed that requires 1.92 (ms) per step in the second stage. A correction variation pattern that is rotated by 340 steps and rotated by 2 steps at a rotation speed that requires 2.56 (ms) per step in the third stage is determined. At this time, the correction operation time of the left reel 206a in each stage is as shown in the figure, and the total operation time is 2478.08 (ms).

  On the other hand, for example, the decorative symbol 190 indicating the result of the lottery determination is determined, the symbol to be stopped as the left symbol 191 is “2” of symbol number 3, and the left symbol 191 displayed on the active line at the start of the correction variation is When the symbol number is “6”, the number of symbols at the time of correction is 8 symbols (see FIG. 12). At this time, if the variable correction variation pattern PT15 is selected by pattern lottery, the number of lottery progression symbols becomes 6 symbols from the lottery correction table of FIG. Therefore, the number of correction symbols to be adjusted by the basic correction variation pattern is 8 symbols−6 symbols = 2 symbols, and the basic correction variation pattern PT3 corresponding to the two symbols is selected from the basic correction table of FIG.

  That is, as shown in FIG. 18B, a combination of the basic correction fluctuation pattern PT3 and the variable correction fluctuation pattern PT15 is determined. Therefore, the correction variation pattern in this case is obtained by adding the rotation amount obtained by adding the rotation amount at each step in the basic correction variation pattern PT3 and the rotation amount at each step in the variable correction variation pattern PT15 to each step. This is the corrected rotation amount at. That is, the left reel 206a is rotated 531 steps at a rotation speed that requires 1.28 (ms) per step in the first stage of correction fluctuation, and at a rotation speed that requires 1.92 (ms) per step in the second stage. A correction variation pattern that is rotated 442 steps and rotated 371 steps at a rotation speed that requires 2.56 (ms) per step in the third stage is determined. At this time, the correction operation time of the left reel 206a in each stage is as shown in the figure, and the total operation time is 2478.08 (ms).

  FIG. 19 is a timing chart illustrating the effects of the correction variation pattern determination method according to the embodiment. 18A shows the correction fluctuation pattern a of FIG. 18A, the middle stage shows the correction fluctuation pattern b of FIG. 18B, and the lower stage shows the correction fluctuation pattern c of FIG. 18C. It is shown. The horizontal axis indicates the passage of time from the start of correction fluctuation. In the figure, numeral “1” indicates the first stage, “2” indicates the second stage, and “3” indicates the third stage.

  That is, as shown in the figure, the correction variation pattern a and the correction variation pattern b have the same number of symbols during the correction period, but a time difference ΔT1 occurs at the start timing of the second stage and ends. A time difference ΔT2 also occurs at the timing. That is, the start timing of the second stage (end timing of the first stage) and the end timing of the second stage (start timing of the third stage) differ from each other even though the number of progress symbols during the correction period is the same.

  On the other hand, the correction fluctuation pattern a and the correction fluctuation pattern b, and the correction fluctuation pattern b and the correction fluctuation pattern c have a constant total correction time even if the number of symbols in the correction period is different. In the present embodiment, the total operation time of the reels from the first stage to the third stage is 1240.32 (ms) in any of the basic correction fluctuation patterns PT1 to PT12, and any of the variable correction fluctuation patterns PT13 to PT20. Also, the total operation time of the reels from the first stage to the third stage is set to 1237.76 (ms). For this reason, the total correction fluctuation time of the correction fluctuation pattern is 2478.08 (ms) for any combination of the basic correction fluctuation pattern and the variable correction fluctuation pattern.

  That is, according to the correction variation pattern determination method of the present embodiment, the time required for each stage is random even if the number of progress symbols during the correction period is the same. On the other hand, even if the number of symbols in progress during the correction period is different, the total correction fluctuation time of the correction fluctuation pattern is constant. For this reason, it is difficult for even a skilled player to determine the stop symbol combination of each reel, and consequently the stop symbol combination of the decorative symbol 190, only by looking at the correction variation. Therefore, it is difficult to predict the result of the success / failure lottery based on the correction fluctuation. In particular, when performing symbol correction in a short time, the time of high-speed fluctuation is almost proportional to the number of correction symbols, but in this embodiment, the number of correction symbols is predicted only by the length of the high-speed fluctuation time It becomes difficult. In addition, although the fluctuation speed and the subsequent constant speed fluctuation in the third stage correction shown in FIG. 19 are the same speed, a part of the second stage correction speed may be inserted immediately before the constant speed fluctuation. By doing in this way, it becomes more difficult to predict the number of corrected symbols.

  FIG. 20 is a flowchart showing a basic operation process in the pachinko gaming machine. First, predetermined power-on processing is executed (S10). This power-on process is to load the game data when the power is turned on and operate the game program normally. This power-on process is normally executed when the power is turned on when the game machine has been successfully started, but is also executed as a power interruption recovery process when the power is turned on again after an unexpected power interruption such as a power failure. . The contents of the disconnection recovery process will be described after the description of the power interruption process in S20 for convenience of explanation.

  Subsequently, processing is performed when a game ball enters the start port 62, the general winning port 72, the big winning port 66, etc. (S11). A normal game control process is executed (S14), and if a normal game is not in progress (N in S12), a special game control process (S16) or a small hit game control process is executed (S17), and S10 is won. Depending on the number of winning balls set in the processing, paying out of winning balls according to various winnings is processed (S18). When the power interruption is detected, the above-described power interruption process is executed (S20).

  FIG. 21 is a flowchart showing in detail the normal game control process of S14 in FIG. In the normal game control process, the execution of the special symbol variation process on the main board 102 (S21) and the execution of the decorative symbol variation process on the sub board 104 (S22) are repeated.

  FIG. 22 is a flowchart showing in detail the execution process of the special symbol variation process of S21 in FIG. If the winning / losing lottery value is held (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). That is, the success / failure lottery means 112 reads the success / failure lottery value and determines the success / failure based on the success / failure lottery value. The symbol determining means 114 determines the stop symbol of the special symbol based on the determination result (S36), and the variation pattern determining means 115 determines the variation pattern of the special symbol (S38). Then, the main board 102 transmits lottery information including the determination result, the special symbol stop symbol, and the special symbol variation pattern information to the sub-board 104 (S40). Then, according to the determination result, the main display control means 118 transmits a change start command to the effect display control means 134 (S42), and starts the special symbol change display (S44).

  If the winning / losing lottery value is not held in S30 (N in S30), the processing from S32 to S44 is skipped, and if the symbol variation is being displayed in S32 (Y in S32), S34 to S44. Processing up to is skipped. Subsequently, if the symbol variation display has already been started (Y of S46), the variation display processing of the special symbol is executed (S48), and the variation time according to the variation pattern has elapsed and the symbol display stop timing has been reached. When (Y of S50), the main display control means 118 transmits a change stop command to the effect display control means 134 (S52), and stops the change of the displayed symbol at a predetermined stop symbol (S54). When the symbol variation display is not started (N in S46), the processing from S48 to S54 is skipped. If the stop timing has not been reached (N in S50), the processes in S52 and S54 are skipped.

  FIG. 23 is a flowchart showing in detail the execution process of the decorative symbol variation process of S22 in FIG. When the effect determining means 132 of the sub board 104 receives the change start command from the main board 102 (Y in S60), the stop pattern of the decorative pattern is determined according to the received special symbol stop pattern, the change pattern, and the determination result. (S62), and the variation effect pattern is determined (S64). Thereafter, the decorative symbol variation display is started (S66). When the variation start command is not received from the main board 102 (N in S60), the processing from S62 to S66 is skipped.

  If the decorative symbol variation display has already been started (Y in S68), the decorative symbol variation display processing is executed (S70), and when the variation stop command is received from the main board 102 (Y in S72), The symbol variation display is stopped by stopping and displaying the decorative symbols in the stop mode determined in S62 (S74). When the change stop command is not received from the main board 102 (N of S72), S74 is skipped. When the variable display has not been started (N in S68), the processing from S70 to S74 is skipped.

  FIG. 24 is a flowchart showing in detail the fluctuation display process of S70 in FIG. If the correction change is not in progress (N in S210) and the correction start timing is reached (Y in S212), the effect determining means 132 executes the correction change determining process (S214), and the effect display control means 134 is determined as the correction change. The correction variation process is started according to the pattern (S216). The correction start timing is determined on the basis of the variation pattern information included in the lottery information when the effect determining unit 132 receives the lottery information from the main board 102. That is, the effect determination unit 132 determines the correction start timing so that the correction variation is completed within the variation time according to the variation pattern. In the present embodiment, a timing before a variation stop timing for receiving a variation stop command is set as a correction start timing. The effect display control means 134 controls the correction variation of the left symbol 191, the middle symbol 193, and the right symbol 195 according to the determined correction variation pattern.

  If it is not the correction start timing (N in S212), the effect display control means 134 executes a decorative symbol variation display process according to the variation effect pattern determined in S64 (S220). If the correction variation is in progress (Y in S210), if the correction variation is completed (Y in S218), the decorative symbol variation display processing according to the variation effect pattern is executed (S220). If the correction variation is continuing (N in S218), the process of S220 is skipped.

FIG. 25 is a flowchart showing in detail the correction variation determination process of S214 in FIG. The effect determining means 132 and the effect display control means 134 execute the processing of this figure for each of the three rows of symbols (left symbol 191, middle symbol 193, and right symbol 195) constituting the decorative symbol. That is, the effect determination means 132 first determines a variable correction variation pattern by pattern lottery using the pattern lottery table of FIG. 17 (S230). Subsequently, with reference to the lottery correction table of FIG. 16B, the lottery progression symbol number C adjusted by the variable correction fluctuation pattern is specified (S232). In addition, as the symbol number A of the symbol to be stopped according to the stop symbol pattern of the decorative symbol determined in S62 and the symbol number B of the symbol currently displayed on the active line, the basic correction variation pattern is expressed by the following equation (1). A fixed correction offset X, which is a difference in the number of symbols to be adjusted, is calculated (S234). Note that D is the number of symbols progressing in the symbol variation after the end of the correction variation, and is the number of symbols traveling in accordance with the constant speed variation and deceleration variation described above.
X = A-B-C-D (For forward rotation)
X = B-A-C-D (in the case of reverse rotation) (1)
In this embodiment, AB here corresponds to “the number of symbols at the time of correction”. At this time, if the fixed correction offset X is a negative value (N in S240), the total number of symbols (12 in this embodiment) is added to the fixed correction offset X (S242), and the result is fixed correction offset X. (S244). If the fixed correction offset X is a positive value or zero (Y in S240), the fixed correction offset X is used as the number of correction symbols, and the basic correction table in FIG. A basic correction variation pattern is selected (S244). Then, the number of steps of the basic correction variation pattern and the variable correction variation pattern determined in this way are added for each stage, and the number of steps after the addition is assigned to each stage is determined as the actual correction variation pattern ( S246). The effect display control means 134 starts correction fluctuation according to the determined correction fluctuation pattern (S248).

  In this embodiment, in the variation with the highest selection frequency (more specifically, the variation up to the temporary stop of the left symbol without shortening, the normal deviation variation, the normal reach variation, the developed reach variation from the normal reach). Since the number D of progressed symbols after the end of the correction fluctuation is an integral multiple of the total number of symbols, it can be said that the calculation of the fixed correction offset X is not substantially affected. For this reason, in the modified example, the progress symbol number D may not be taken into consideration only during the standard variation pattern. Further, in any variation pattern, if the number D of progress symbols is set to be an integral multiple of the total number of symbols, it is possible to set so as not to consider in all variation patterns.

  FIG. 26 is a flowchart showing in detail the special game control process of S16 in FIG. If the result of the lottery is a big hit (Y in S90), the special game has already started (Y in S92), and the grand prize opening 66 has not been opened (N in S98), the big prize opening The release process 66 is executed (S100). At this time, display of the set jackpot effect is also started. If the big prize opening 66 has been opened (Y of S98), the closing process of the big prize opening 66 is executed (S102). As a result, if the special winning opening 66 is closed (Y in S104), the process proceeds to S106. If it is not in the closed state (N in S104), the process after S106 is skipped, and this process is temporarily ended. On the other hand, if the special game has not started in S92 (N in S92), the special game is started (S94), the display of the start demonstration effect is started (S96), and this process is temporarily ended.

  In S106, it is determined whether or not a demonstration production, which is a production during a special game, is being performed. Note that the “demonstration effect” here includes a start demonstration effect and an end demonstration effect. If the demonstration is not in progress (N in S106), it is determined whether or not a special game end condition is satisfied with reference to an end flag described later (S110), and if the special game end condition is satisfied (S110). Y) After the end flag is turned off (S112), display of the end demonstration effect is started (S114). If the special game end condition is not satisfied (N in S110), this process is temporarily ended. If it is determined in S106 that the demonstration effect is being performed (Y in S106), and the end demonstration effect is completed (Y in S116), the special game is terminated (S118), and the specific game, that is, the probability change, the time reduction, and the entry The easy state is started (S120). If the end demonstration effect has not ended (N in S116), the processes in S118 and S120 are skipped. If it is not a big hit (N in S90), the flow after S92 in this figure is skipped.

  FIG. 27 is a flowchart showing in detail the release process of S100 in FIG. When the opening timing of the special winning opening 66 based on the set opening / closing pattern is reached (Y in S122), the opening / closing control means 124 uniformly turns off the passage flag and sets the operation of the opening / closing pattern (S124). The special winning opening 66 is opened (S126). In addition, a big hit effect corresponding to the number of repetitions of the current unit game or a big hit effect corresponding to the number of repetitions being different is set and started. When it is not the opening timing (N of S122), the processes of S124 and S126 are skipped.

  FIG. 28 is a flowchart showing in detail the closing process of S102 in FIG. When the closing timing of the special winning opening 66 based on the set opening / closing pattern is reached, the open / close control means 124 closes the special winning opening 66. That is, during a special game, whether the end condition based on the number of balls is satisfied (Y in S130) or the end condition based on the number of balls is not satisfied (N in S130), the end condition based on the opening time is satisfied ( (Y of S132), the special winning opening 66 is closed (S134). If the termination condition based on the opening time is not satisfied (N in S132), the flow after S134 is skipped.

  The end condition based on the number of balls in the 15R jackpot is 10 or more balls entering the grand prize opening 66, and the end condition based on the opening time is a set time according to the opening / closing pattern from the opening start of the big prize opening 66. It is progress. In the case of 15R big hit, 30 seconds have elapsed since the start of opening, and in the case of 2R big hit, 0.5 seconds have elapsed since the start of opening. However, since the opening for 0.5 seconds is extremely short, it is difficult to enter more than 10 balls as well as to enter the ball itself. Even if a game ball is launched at the same time as the opening of the grand prize opening, it is difficult to enter the game, so it is predicted that the 2R big hit will be opened before the grand prize opening 66 is opened. It is necessary to launch a game ball. On the other hand, the end condition based on the number of balls in the 15R jackpot is 10 or more balls entering the grand prize opening, and the end condition based on the opening time is 30 seconds from the start of opening the big prize opening 66. At this time, if the maximum number of continuations has been reached (Y in S136), the end flag is turned on (S138). If the maximum number of continuations has not been reached (N in S136), the process in S138 is skipped. In this embodiment, the upper limit number of continuations is 15 times. If neither the end condition based on the number of entered balls nor the end condition based on the opening time is satisfied (N in S130, N in S132), the processes after S134 are skipped.

  FIG. 29 is a flowchart showing in detail the small hit game control process of S17 in FIG. If the result of the lottery is a small hit (Y in S150), the small hit game has already started (Y in S152), and the big winning opening 66 has not been opened (N in S158). A process for opening the winning opening 66 is executed (S160), and if it is already opened (Y in S158), a closing process for the big winning opening 66 is executed (S162). As a result, if the special winning opening 66 is closed (Y in S164), the process proceeds to S166. If it is not in the closed state (N of S164), the process after S166 is skipped and this process is temporarily ended. On the other hand, if the small hit game has not started in S152 (N in S152), the small hit game is started (S154), and the display of the start demonstration effect similar to the 2R big hit is started (S156). Exit once.

  In S166, it is determined whether or not a demonstration effect which is an effect during the small hit game is being performed. If the demonstration effect is not in progress (N in S166), it is determined whether or not the small hit game end condition is satisfied. Here, if an end flag, which will be described later, is on, the small hit game end condition is satisfied. If the small hit game end condition is satisfied (Y in S170), the end flag is turned off (S172), and the display of the end demonstration effect is started (S174). If the small hit game ending condition is not satisfied (N in S170), this process is temporarily ended. When it is determined in S166 that the demonstration effect is being performed (Y in S166) and the end demonstration effect is completed (Y in S176), the small hit game is terminated (S178). If the end demonstration effect has not ended (N in S176), the process of S178 is skipped. If it is not a small hit (N in S150), the flow after S152 in this figure is skipped.

  FIG. 30 is a flowchart showing in detail the release process of S160 in FIG. When it is the opening timing of the big winning opening 66 based on the set opening / closing pattern (Y in S180), the opening / closing control means 124 sets the operation of the opening / closing pattern (S182) and starts opening the big winning opening 66. (S184). When it is not the opening timing (N of S180), the processing of S182 and S184 is skipped.

  FIG. 31 is a flowchart showing in detail the closing process of S162 in FIG. When the end timing of the special winning opening 66 based on the set opening / closing pattern is reached (Y in S190), the end flag is turned on (S192), and the special winning opening 66 is closed (S194). This closing timing is the timing when 0.5 seconds have elapsed since the opening of the special winning opening 66. If it is not the closing timing (N of S190), the processes of S192 and S194 are skipped.

  FIG. 32 is a flowchart showing in detail the power interruption process in S20 of FIG.

  When the power interruption signal is input to the main board 102 (Y of S220), the normal game process shown in FIGS. 16 to 24 is stopped, and the process of storing the game state including the symbol variation information is executed. The power interruption recovery control means 128 identifies game data to be backed up, generates a checksum (hereinafter referred to as “first checksum”), and records it in the backup RAM (S222). The checksum generation method may be a known method, for example, a predetermined addition process is performed on specific lower bits of the game data. The game data specified at this time includes halfway state data, and the power interruption return control means 128 saves the game data in the backup RAM (S224). When the game data backup is completed normally, the normal processing flag set in the predetermined area of the backup RAM is turned on (S226). On the other hand, if no power interruption signal is input (N in S220), this process is skipped. In the modification, the process of S226 may be omitted.

  FIG. 33 is a flowchart showing in detail the power interruption recovery process related to S10 of FIG. When the power is turned off and then on again as described above, the sub board 104 is activated first, and then the main board 102 is activated. In this embodiment, the power supply timing from the power supply unit 48 to the main board 102 is delayed by a set time from the power supply timing to the sub board 104 when the power is restored, so that the sub board 104 is started before the main board 102. Let In the modified example, the timing of the reset process executed on the main board 102 when the power is turned on is delayed from the timing of the reset process executed on the sub board 104, so that the sub board 104 is moved to the main board 102. You may make it start before. This is to prevent the sub board 104 from missing various command information including a gaming state transmitted from the main board 102 together with the power interruption return command when the main board 102 is activated. If the RAM clear switch 92 is turned on (Y in S230), the power interruption return control means 128 causes the initialization execution means 127 to execute the initialization process described above (S232). At this time, if game data such as halfway status data is held in the backup RAM, it is erased. When the RAM clear switch 92 is not turned on (N in S230), a “reproduction process” for reproducing the gaming state when the power is shut off is executed. That is, the power interruption recovery control means 128 first refers to the backup RAM and determines whether the normality determination flag is turned on. If the normality determination flag is turned on (Y in S234), the halfway state data is loaded from the backup RAM to the processing RAM, and the first checksum generated when the power is shut off is also acquired. Subsequently, a new checksum (hereinafter referred to as “second checksum”) is generated from the loaded halfway state data by the same method as the first checksum generation method, and the first checksum and the second checksum are generated. It is determined whether or not the thumb matches. At this time, if the two checksums match (Y in S236), the gaming state when the power is shut off is reproduced based on the loaded halfway state data (S238).

  If the symbol variation is interrupted in the middle when the power is shut off, the power interruption recovery control means 128 causes the main display control means 118 to resume the symbol variation of the special symbol 192 when the power is turned on again on the main board 102. Further, the power interruption return control means 128 transmits a power interruption return command indicating that the symbol variation has been resumed to the sub-board 104. Along with this power interruption return command, information indicating that the game is changing when the power is restored on the main board 102 and information such as the hold status of the lottery result are sent to the sub board 104. On the sub-board 104, the effect display control means 134 starts driving the reel unit 60, and the position determination means 136 detects the position of each reel. As described above, the symbol form determining unit 131 determines the shortest stop symbol pattern based on the detected symbol information, and the effect display control unit 134 stops and displays the stop symbol according to the shortest symbol pattern. Control. The specific processing contents of the decorative symbol fluctuation return control will be described later. Then, the normal processing flag is turned off (S240), and this processing is temporarily ended.

  On the other hand, if the normal processing flag is off (N in S234), if the checksums do not match (N in S236), the process proceeds to S232 to execute the initialization process, and the initial state is read from the ROM. Load data and start playing from the initial state.

  FIG. 34 is a flowchart showing in detail the fluctuation return process related to S238 of FIG. When a power failure return command is transmitted from the main board 102 and received on the sub board 104 side (Y in S250), the effect display control means 134 starts rotating the left reel 206a (S252). When the left symbol 191 that first reaches the first effective line L1 is detected (Y in S254), the left symbol 191 is pseudo-stopped on the first effective line L1 (S256). That is, it is a slight fluctuation fluctuation.

  Subsequently, the rotation of the middle reel 206b is started (S258). When the middle symbol 193 that first reaches the first effective line L1 is detected (Y in S260), the middle symbol 193 is pseudo-stopped on the first effective line L1 (S262). That is, it is a slight fluctuation fluctuation. The symbol design determining means 131 can stop the specific symbol combination including the right symbol 195 in the shortest time by referring to the return symbol determination table using the symbol number combination of the left symbol 191 and the middle symbol 193 that are pseudo-stopped at this time. The shortest stop symbol pattern is determined (S264). Then, the effect display control means 134 starts to rotate the right reel 206c (S266). If it is detected that the right symbol 195 according to the shortest stop symbol pattern has reached the first effective line L1 (Y in S268), the right symbol 195 is pseudo-stopped on the first effective line L1 (S270). . That is, it is a slight fluctuation fluctuation. When the change stop command is transmitted from the main board 102 and received on the sub board 104 side (Y in S272), the effect display control means 134 determines all of the left symbol 191, the middle symbol 193, and the right symbol 195. (S274). If the power failure recovery command is not received (N in S250), this process is temporarily terminated.

  As described above, in this embodiment, the actual correction fluctuation pattern is obtained by adding the basic correction fluctuation pattern associated with the difference in the number of symbols and the variable correction fluctuation pattern determined by lottery for each stage. Is determined. Accordingly, the rotation amount obtained by adding the rotation amount (number of steps) at each rotation speed in the basic correction variation pattern and the rotation amount (number of steps) at each rotation speed in the variable correction variation pattern is determined as each rotation speed. The correction variation is executed with the correction rotation amount at. That is, by adding a variable correction variation pattern by lottery to the basic correction variation pattern according to the symbol number difference, even if the symbol number difference is the same, the reel rotation time at each stage is random (variation). Can be provided. As a result, even a skilled person cannot easily determine the stop symbol based on the symbol position correction, and the game entertainment can be maintained.

  Further, in this embodiment, a plurality of types of correction variation patterns defined in the basic correction table are set to be equal regardless of the number of symbols in the total correction time in all stages, and the plurality of types defined in the lottery correction table are used. The total correction time of all the stages is also set equal regardless of the number of symbols. For this reason, the correction time combining the basic correction variation pattern and the variable correction variation pattern can always be kept constant. For this reason, the execution period of the correction variation can be limited to a certain period during the symbol variation according to the determined variation pattern.

[Example 2]
The pachinko gaming machine 10 of the present embodiment is mainly different from the first embodiment in the method of fluctuation return processing. Since other configurations and game methods are basically the same as those in the first embodiment, differences will be mainly described and description of common points will be omitted.

  In this embodiment, the basic correction fluctuation pattern and the variable correction fluctuation pattern are not added as in the first embodiment, but the correction fluctuation due to the variable correction fluctuation pattern is continued after the correction fluctuation due to the basic correction fluctuation pattern. The correction variation pattern is determined. However, when determining the correction fluctuation pattern, the variable correction fluctuation pattern is first determined by pattern lottery, and is adjusted by the basic correction fluctuation pattern according to the number of lottery progress symbols, which is the difference in the number of symbols adjusted by the variable correction fluctuation pattern. A correction symbol number that is a difference in the number of symbols to be determined is determined, and a basic correction variation pattern corresponding to the correction symbol number is determined.

  FIG. 35 is a diagram schematically illustrating a correction table according to the second embodiment. The effect determining means 132 refers to the basic correction table shown in FIG. 35 (a) and the lottery correction table shown in FIG. 35 (b) when determining the correction fluctuation pattern that determines the fluctuation process of the correction fluctuation. This embodiment is common to the first embodiment in that the symbol variation speeds in the basic correction table and the lottery correction table change in three stages, respectively. However, the correction variation due to the variable correction variation pattern is changed after the correction variation due to the basic correction variation pattern. It differs from the first embodiment in that it is set to be performed. In addition, since the rotation speed of the reel at the final stage of the basic correction fluctuation pattern and the rotation speed of the reel at the first stage of the variable correction fluctuation pattern are common and the rotation speeds at other stages are different, the correction fluctuation pattern as a whole In the correction period, it seems that the fluctuation speed of the symbol changes in five stages.

  As shown in FIG. 35A, the basic correction variation pattern is the same as that of the first embodiment shown in FIG. On the other hand, as shown in FIG. 35B, in the lottery correction table, similarly to the basic correction fluctuation pattern, the variable correction fluctuation patterns PT21 to PT32 are associated with the correction symbol numbers “0” to “11”. ing. Specifically, the correction symbol number “11” is associated with the variable correction variation pattern PT21, and the correction symbol numbers “0” to “10” are associated with the variable correction variation patterns PT22 to PT32. . As shown in the figure, the variable correction fluctuation pattern has its first stage rotational speed set to a speed that requires 2.56 (ms) per step, and is the same as the third stage of the basic correction fluctuation pattern. . On the other hand, the second stage rotational speed of the variable correction variation pattern is 3.20 (ms) per step, and the third stage rotational speed of the pattern is 3.84 (ms) per step. The speed is set to be gradually slower than the basic correction fluctuation pattern. Since the first to third steps of the variable correction variation pattern are corrected so as to continue after the first to third steps of the basic correction variation pattern, the fourth correction variation pattern is the fourth. It is positioned in stage-6.

  FIG. 36 is a diagram schematically showing a pattern lottery table. The effect determination means 132 refers to the illustrated pattern lottery table when determining the variable correction variation pattern. In this pattern lottery table, the pattern lottery values “0 to 255” are assigned almost evenly to the variable correction variation patterns PT21 to PT32 described above. The effect determining means 132 determines a variable correction variation pattern by pattern lottery using the pattern lottery table, and refers to the lottery correction table of FIG. 35B using the variable correction variation pattern. Then, the number of lottery progress symbols corresponding to the variable correction variation pattern is specified, and the difference in the number of symbols between the number of symbols in progress and the number of symbols in the lottery progress is calculated as the number of corrected symbols. Subsequently, the basic correction variation pattern is determined by referring to the basic correction table of FIG. Then, the correction variation pattern is determined so that the basic correction variation pattern determined in this way and the determined variable correction variation pattern are made continuous.

  FIG. 37 is a diagram specifically illustrating a correction variation pattern determination method. FIG. 37A shows a case where the number of symbols at the time of correction is nine symbols and the variable correction variation pattern PT28 is selected by pattern lottery. FIG. 37 (b) shows a case where the number of symbols at the time of correction is 9 symbols and the variable correction variation pattern PT21 is selected by pattern lottery. FIG. 37 (c) shows a case where the number of symbols at the time of correction is 2, and the variable correction variation pattern PT21 is selected by pattern lottery. In the following description, the correction variation pattern determination method will be described by taking the left symbol 191 as an example, but the same determination method is also applied to the middle symbol 193 and the right symbol 195.

  For example, the decorative symbol 190 indicating the result of the lottery determination is determined, the symbol to be stopped as the left symbol 191 is “1” of symbol number 1, and the left symbol 191 displayed on the active line at the start of the correction variation is the symbol When the number is “*”, the number of symbols at the time of correction is 9 symbols (see FIG. 12). At this time, if the variable correction variation pattern PT28 is selected by pattern lottery, the number of lottery progression symbols is six symbols from the lottery correction table of FIG. Therefore, the number of correction symbols to be adjusted by the basic correction variation pattern is 9 symbols−6 symbols = 3 symbols, and the basic correction variation pattern PT4 corresponding to the 3 symbols is selected from the basic correction table of FIG.

  That is, as shown in FIG. 37A, a combination of the basic correction fluctuation pattern PT4 and the variable correction fluctuation pattern PT28 is determined. For this reason, the left reel 206a is rotated 282 steps at a rotation speed that requires 1.28 (ms) per step in the first stage of correction fluctuation, and a rotation speed that requires 1.92 (ms) per step in the second stage. 18 steps, and in the third stage, it is rotated 330 steps at a speed that requires 2.56 (ms) per step, and in the fourth stage, it is rotated 916 steps at a speed that requires 2.56 (ms) per step. The correction fluctuation is rotated by 10 steps at a rotation speed requiring 3.20 (ms) per step in the fifth stage, and rotated by 334 steps at a rotation speed requiring 3.84 (ms) per step in the sixth stage. A pattern is determined. At this time, the correction operation time of the left reel 206a at each stage is as shown in the figure, and the total operation time is 4899.84 (ms). Further, the operation time of the third stage (the third stage of the basic correction fluctuation pattern) and the fourth stage (the first stage of the variable correction fluctuation pattern) at which the rotation speed requires 2.56 (ms) per step is 3189. 76 (ms).

  Similarly, the decorative symbol 190 indicating the result of the lottery determination is determined, and the symbol to be stopped as the left symbol 191 becomes “1” of symbol number 1, and the left symbol 191 displayed on the active line at the start of the correction variation. Even if the symbol number is “*”, if the variable correction fluctuation pattern is different, the correction fluctuation pattern is also different. For example, when the variable correction variation pattern PT21 is selected by pattern lottery, the number of lottery progression symbols is 11 symbols from the lottery correction table of FIG. Therefore, since the number of correction symbols to be adjusted by the basic correction variation pattern is 9 symbols-11 symbols = -2 symbols, the total number of symbols of 12 symbols is added to adjust the difference in the number of symbols, and −2 symbols + 12 This means that the symbol = 10 symbols, and the basic correction variation pattern PT11 corresponding to the 10 symbols is selected from the basic correction table of FIG.

  That is, as shown in FIG. 37B, the combination of the basic correction fluctuation pattern PT11 and the variable correction fluctuation pattern PT21 is determined. For this reason, the left reel 206a is rotated 877 steps at a rotation speed that requires 1.28 (ms) per step in the first stage of correction fluctuation, and a rotation speed that requires 1.92 (ms) per step in the second stage. 4 steps, 43 steps are rotated at a speed of 2.56 (ms) per step in the third stage, and 27 steps are rotated at a speed of 2.56 (ms) per step in the fourth stage. The correction variation is rotated 24 steps at a rotation speed requiring 3.20 (ms) per step in the fifth stage and 915 steps at a rotation speed requiring 3.84 (ms) per step in the sixth stage. A pattern is determined. At this time, the correction operation time of the left reel 206a at each stage is as shown in the figure, and the total operation time is 4899.84 (ms). In addition, the operation time of the third stage (the third stage of the basic correction fluctuation pattern) and the fourth stage (the first stage of the variable correction fluctuation pattern) at which the rotation speed requires 2.56 (ms) per step is 179. 20 (ms).

  On the other hand, for example, the decorative symbol 190 indicating the result of the lottery determination is determined, the symbol to be stopped as the left symbol 191 is “1” of symbol number 1, and the left symbol 191 displayed on the active line at the start of the correction variation is When the symbol number 3 is “2”, the number of symbols at the time of correction is 2 symbols (see FIG. 12). At this time, if the variable correction variation pattern PT21 is selected by pattern lottery, the number of lottery progressing symbols is 11 symbols from the lottery correction table of FIG. Therefore, since the number of correction symbols to be adjusted by the basic correction variation pattern is 2 symbols−11 symbols = −9 symbols, the total number of symbols of 12 symbols is added to adjust the difference in the number of symbols, and −9 symbols + 12 This means that the symbol = 3 symbols, and the basic correction variation pattern PT4 corresponding to the three symbols is selected from the basic correction table of FIG. Here, since there is no pattern in which the number of correction symbols is negative as the basic correction variation pattern, adjustment is performed by adding the total number of symbols. However, in the modification, the number of correction symbols is negative as the basic correction variation pattern. A pattern may be further provided, and a basic correction variation pattern in which the number of correction symbols is −9 symbols may be selected.

  That is, as shown in FIG. 37C, a combination of the basic correction fluctuation pattern PT4 and the variable correction fluctuation pattern PT21 is determined. For this reason, the left reel 206a is rotated 282 steps at a rotation speed that requires 1.28 (ms) per step in the first stage of correction fluctuation, and a rotation speed that requires 1.92 (ms) per step in the second stage. 18 steps, and in the third stage, it is rotated by 330 steps at a speed that requires 2.56 (ms) per step, and in the fourth stage, it is rotated by 27 steps at a speed that requires 2.56 (ms) per step. The correction variation is rotated 24 steps at a rotation speed requiring 3.20 (ms) per step in the fifth stage and 915 steps at a rotation speed requiring 3.84 (ms) per step in the sixth stage. A pattern is determined. At this time, the correction operation time of the left reel 206a at each stage is as shown in the figure, and the total operation time is 4899.84 (ms). The operation time of the third stage (the third stage of the basic correction fluctuation pattern) and the fourth stage (the first stage of the variable correction fluctuation pattern) at which the rotation speed requires 2.56 (ms) per step is 913. 92 (ms).

  FIG. 38 is a timing chart illustrating the effect of the correction variation pattern determination method according to the embodiment. The upper part of FIG. 37 shows the correction fluctuation pattern a of FIG. 37A, the middle part of FIG. 37B shows the correction fluctuation pattern b, and the lower part of FIG. 37C shows the correction fluctuation pattern c of FIG. It is shown. The horizontal axis indicates the passage of time from the start of correction fluctuation. In the figure, the number “1” is the first stage, “2” is the second stage, “3” is the third stage, “4” is the fourth stage, “5” is the fifth stage, and “6” is the third stage. Each of the sixth stages is shown.

  That is, as shown in the figure, the correction variation pattern a and the correction variation pattern b have a time difference in the start and end timing of each stage, even though the number of progress symbols during the correction period is the same. Further, there is a difference between ΔT3 of the correction fluctuation pattern a and ΔT4 of the correction fluctuation pattern b with respect to the operation time of the third stage and the fourth stage operating at the common rotational speed. That is, although the number of symbols in progress during the correction period is the same, the correction variation pattern is completely different.

  On the other hand, the correction fluctuation pattern a and the correction fluctuation pattern b, and the correction fluctuation pattern b and the correction fluctuation pattern c have a constant total correction time even if the number of symbols in the correction period is different. In this embodiment, the total of the operation time of the reels from the first stage to the third stage is 1240.32 (ms) in any of the basic correction fluctuation patterns PT1 to PT12, and any of the variable correction fluctuation patterns PT21 to PT32. Also, the total operation time of the reels from the first stage to the third stage is set to be 365.52 (ms). For this reason, the total correction fluctuation time of the correction fluctuation pattern is 4899.84 (ms) for any combination of the basic correction fluctuation pattern and the variable correction fluctuation pattern.

  That is, according to the correction variation pattern determination method of the present embodiment, the time required for each stage is random even if the number of progress symbols during the correction period is the same. On the other hand, even if the number of symbols in progress during the correction period is different, the total correction fluctuation time of the correction fluctuation pattern is constant. For this reason, it is difficult for even a skilled player to determine the stop symbol combination of each reel, and consequently the stop symbol combination of the decorative symbol 190, only by looking at the correction variation. Therefore, it is difficult to predict the result of the success / failure lottery based on the correction fluctuation.

FIG. 39 is a flowchart showing in detail the correction variation determination process applied to S214 in FIG. The correction variation determination process of the present embodiment is executed in place of the correction variation determination process of FIG. The effect determining means 132 and the effect display control means 134 execute the processing of this figure for each of the three rows of symbols (left symbol 191, middle symbol 193, and right symbol 195) constituting the decorative symbol. That is, the effect determination means 132 first determines a variable correction variation pattern by pattern lottery using the pattern lottery table of FIG. 36 (S230). Subsequently, with reference to the lottery correction table of FIG. 35B, the lottery progression symbol number C adjusted by the variable correction fluctuation pattern is specified (S232). In addition, the symbol number A of the symbol scheduled to stop according to the stop symbol mode of the decorative symbol determined in S62 and the symbol number B of the symbol currently displayed on the active line are expressed by the basic correction variation pattern according to the following equation (2). A fixed correction offset X, which is a difference in the number of symbols to be adjusted, is calculated (S234). Note that D is the number of symbols progressing in the symbol variation after the end of the correction variation.
X = A-B-C-D (For forward rotation)
X = B-A-C-D (in the case of reverse rotation) (2)
In addition, AB here corresponds to "the number of symbols at the time of correction." At this time, if the fixed correction offset X is a negative value (N in S240), the total number of symbols (12 in this embodiment) is added to the fixed correction offset X (S242), and the result is fixed correction offset X. (S244). If the fixed correction offset X is a positive value or zero (Y in S240), the fixed correction offset X is used as the number of correction symbols, and the basic correction table in FIG. A basic correction variation pattern is selected (S244). Then, the basic correction fluctuation pattern determined in this way is determined as the first correction and the variable correction fluctuation pattern as the latter half is determined as the actual correction fluctuation pattern (S247). The effect display control means 134 starts correction fluctuation according to the determined correction fluctuation pattern (S248).

  In this embodiment, since the number D of progressed symbols after the end of the correction variation is an integral multiple of the total number of symbols, it can be said that the calculation of the fixed correction offset X is not substantially affected. For this reason, you may make it not take into consideration the number D of progress symbols.

  As described above, also in this embodiment, the actual correction fluctuation pattern is obtained by adding the basic correction fluctuation pattern associated with the difference in the number of symbols and the variable correction fluctuation pattern determined by lottery for each stage. Is determined. Then, the correction fluctuation is executed according to the correction fluctuation pattern in which the basic correction fluctuation pattern is the first half and the variable correction fluctuation pattern is the second half. In particular, after the variable correction variation pattern is randomly determined by lottery, the basic correction variation pattern is determined so as to match the number of symbols according to the number of symbols in the variable correction variation pattern lottery progress, so one correction A combination of a plurality of types of basic correction variation patterns and variable correction variation patterns can be selected with respect to the number of time progression symbols. That is, even when the number of symbols at the time of correction is the same, it is possible to give randomness (variation) to the rotation time of the reel at each stage. Also, the reel rotation speed in the final stage (third stage) of the basic correction table is equal to the reel rotation speed in the first stage (first stage: fourth stage of the entire correction variation pattern) of the lottery correction table. Is set to For this reason, it becomes difficult to distinguish the boundary between the correction fluctuation at the final stage of the basic correction fluctuation pattern and the correction fluctuation at the first stage of the variable correction fluctuation pattern. Identification can be difficult.

  Also in this embodiment, a plurality of types of correction variation patterns defined in the basic correction table are set to be equal regardless of the number of symbols in the total correction time of all stages, and a plurality of correction variation patterns defined in the lottery correction table are defined. The correction correction patterns of the types are also set to have the same total correction time regardless of the number of symbols. For this reason, the correction time of the basic correction variation pattern and the variable correction variation pattern can be always kept constant, and the execution period of the correction variation is limited to a certain period during the symbol variation according to the determined variation pattern. Can do.

  The embodiment has been described above. 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.

(Modification 1)
In each of the above embodiments, as shown in FIGS. 16 and 35, an example in which one type of basic correction table and lottery correction table are provided is shown. In the modification, a plurality of these correction tables may be provided and set so as to be switched according to the gaming state. FIG. 40 is a diagram schematically illustrating a part of the correction table according to the modification of the first embodiment.

  The effect determining means 132 refers to the basic correction table shown in FIG. 16A and the lottery correction table shown in FIG. 16B when the correction fluctuation pattern for determining the fluctuation process of the correction fluctuation is determined. On the other hand, in the non-time saving state, the basic correction table shown in FIG. 40A and the lottery correction table shown in FIG. 40B are referred to.

  That is, in the basic correction table shown in FIG. 40A, the reel rotation speed at each stage is set to a low speed (1/2 speed in the illustrated example) as compared to the basic correction table shown in FIG. ing. Also, in the lottery correction table shown in FIG. 40B, the reel rotation speed at each stage is set to a low speed (1/2 speed in the illustrated example) as compared to the lottery correction table shown in FIG. ing. In this modification, the basic correction table shown in FIG. 40A corresponds to the “first basic correction table”, and the lottery correction table shown in FIG. 40B corresponds to the “first lottery correction table”. . 16A corresponds to the “second basic correction table”, and the lottery correction table illustrated in FIG. 16B corresponds to the “second lottery correction table”.

  Therefore, in the time reduction state, the total operation time of the reel during the correction period is 2478.08 (ms) as in the first embodiment, but in the non-time reduction state, the total operation time of the reel during the correction period. Is 4956.16 (ms), which is twice that of the first embodiment. That is, since the symbol variation time is shorter in the time-short state than in the normal state (non-time-short state), the correction time is set to a short time so that the correction variation is within the short time. On the other hand, in the non-time-short state, since the symbol variation time becomes relatively long, the correction time is also set long enough. By setting in this way, it is possible to reliably complete the correction variation during a short time when the symbol variation time is short. Further, since the symbol variation time is relatively long in the non-time-short state, the reel drive control can be executed with a sufficient margin. If it is necessary to further shorten the total operation time in the time-saving state, the rotation of the reel at each stage is compared with the basic correction table shown in FIG. A high speed (for example, twice the speed) is provided, and the lottery correction table also has a higher reel rotation speed at each stage than the lottery correction table shown in FIG. For example, a double speed) may be provided, and a table using them may be used as the time reduction table.

  In this modification, two examples of the basic correction table and the lottery correction table are provided. However, at least one of the basic correction table and the lottery correction table is provided, and any one of the basic correction table and the lottery correction table is selected depending on the gaming state. A correction table may be selected. In the present modification, an example is shown in which a table with a different correction period is provided for the correction table of the first embodiment shown in FIG. 16, but the same applies to the correction table of the second embodiment shown in FIG. A table with a different correction period may be provided, and any correction table may be referred to according to the gaming state.

  Alternatively, in the time reduction state, the basic correction table and the lottery correction table of the first embodiment are referred to in which the total operation time of the reels in the correction period is relatively short (see FIG. 16). The basic correction table and lottery correction table of the second embodiment may be referred to (see FIG. 35).

(Modification 2)
In the first modification, an example in which the basic correction table and the lottery correction table are switched so that the correction time is relatively short in the time-short state has been described. You may make it switch a basic correction table and a lottery correction table so that correction time may become relatively short when it will be in a shortened state. Further, the basic correction table and the lottery correction table may be switched so that the correction time is relatively short in the time-short state and the ultra-short state, or the time-short state and the short state.

(Modification 3)
In each of the above-described embodiments and modifications, a plurality of types of tables with different correction periods are provided as the basic correction table, and a plurality of types of tables with different correction periods are provided as the lottery correction table. An example is shown in which the basic correction table and the lottery correction table are set so that the correction period is within the pattern fluctuation time. In the modification, a plurality of types of tables having different correction periods are provided for only one of the basic correction table and the lottery correction table, and one of the correction periods falls within the variation time of the variation pattern determined according to the gaming state. The correction table may be set.

(Modification 4)
In the first embodiment, as shown in FIG. 16B, the lottery correction table shows an example in which up to 3 symbols, which are smaller than the total number of symbols (12 symbols), are set as the number of correction progress symbols. In a modification, the same number of correction progress symbols as the total number of symbols (12 symbols) may be set for the lottery correction table. By setting in this way, it is possible to increase variations that can be set as the correction variation pattern, and to make it more difficult to specify the symbols to be stopped based on the correction variation.

(Modification 5)
Alternatively, as the lottery correction table, a normal lottery correction table and a specific lottery correction table in which the correction period is set longer than the normal lottery correction table are provided, and the normal lottery correction table is set and specified in the normal gaming state. In the gaming state, a specific lottery correction table may be set. For example, referring to the basic correction table and the lottery correction table shown in FIG. 16, FIG. 40 shows that the winning lottery value in which the result of the winning / failing lottery becomes a probable big hit with a shift to probability variation is suspended. You may make it switch to a basic correction table and a lottery correction table. With such a setting, it is possible to indicate in advance that the correction variation is longer than usual and that it will be a probable big hit. That is, it becomes possible to use the correction fluctuation in a notice effect.

  For example, the specific lottery correction table may be set by prefetching the result of the winning / losing lottery being held and when a specific jackpot is held. Specifically, when the winning / throwing lottery means that there is a new entry to the starting gate, whether or not the change display of the special symbol corresponding to the entry starts immediately, Information indicating the result of the corresponding lottery determination is transmitted to the effect determining means. When the information indicating the result of the lottery determination is received, the effect determining means becomes a specific big hit in the lottery result regardless of whether or not the display of the special symbol corresponding to the entry is started immediately. Determine if there is something. The specific lottery correction table may be set when a specific jackpot is included.

(Modification 6)
In the second embodiment, the basic correction fluctuation pattern and the variable correction fluctuation pattern are selected and determined as an integrated correction fluctuation pattern in which they are made continuous, and then the correction fluctuation is started. In the modification, after selecting the basic correction variation pattern and the variable correction variation pattern, first setting the basic correction variation pattern and executing the correction variation, then setting the variable correction variation pattern and setting the correction variation. You may make it perform.

(Modification 7)
In each of the above-described embodiments, as illustrated in S214 of FIG. 24, the correction start timing is determined on the sub-substrate 104 side. In the modification, the correction start timing may be determined on the main board 102 side. That is, the correction start timing corresponding to the variation pattern is set in advance on the main board 102 side, the variation time is measured together with the variation start of the special symbol, and when the correction start timing is reached, a correction start command indicating that is sub You may transmit toward the board | substrate 104. FIG. Then, the correction variation determination process may be started when the sub-board 104 receives the correction start command.

(Modification 8)
In the above embodiment, it is premised on fluctuation control without a temporary stop, but when performing fluctuation with a temporary stop, correction control is performed by regarding the temporary stop pattern as a stop pattern, Further, the correction may be executed at an appropriate timing between the temporary stop and the actual stop. In addition, even when there are a plurality of variation patterns having different final variation times, the correction related to the first stop and the second stop reel at the time of the normal deviation variation without the reach effect, and the reach effect By adopting this correction method for the first stop and second stop (including provisional stop) corrections for reach fluctuations that involve a change in reach, whether or not reach fluctuations will occur. It becomes impossible to identify, and it is possible to maintain a game entertainment interest.

(Modification 9)
In the above embodiment, as shown in FIGS. 9 and 10, twelve detection pieces 235 corresponding to the number of symbols arranged on the reel 206 (a total of twelve numeric symbols and blank symbols) are provided to detect the position. An example is shown in which the sensor 215 detects the position of the reel 206 in the rotational direction, and thus the symbol positioned on the effective line. In the modification, for example, a number of detection pieces corresponding to a number symbol or a blank symbol may be provided, and the position detection sensor 215 may detect them. In this case, whether or not a symbol that does not correspond to the detection piece 235 is positioned on the effective line may be calculated from the number of steps of the motor 217 based on the position of the symbol that the detection piece 235 corresponds to. Alternatively, one or a plurality of detection pieces 235 and a plurality of position detection sensors 215 may be provided so that a plurality of symbols can be detected.

(Modification 10)
In the above embodiment, as shown by the solid line in FIG. 14, the rotation of the left symbol 191, the middle symbol 193, and the right symbol 195 is started in this order, and stopped in the same order. In the modification, the rotation of all the reels of the left symbol 191, the middle symbol 193, and the right symbol 195 may be started simultaneously and stopped in a predetermined order. That is, the rotation start timing of each reel may be the same, while the rotation stop timing may be sequentially performed.

(Modification 11)
In the above embodiment, a configuration is shown in which the game control state is not backed up when the power is cut off on the sub-board 104 side. In a modified example, the game control state at the time of power-off may be backed up also on the sub-board 104 side. However, even if such a backup is performed on the sub-board 104 side, it takes time until the rotation of each reel stops after the power is turned off. That is, the position information of each reel is almost meaningless even if it is backed up. For this reason, it is meaningful to perform the process for resuming the symbol variation after receiving the power supply return command in the sub-board 104 as in the above embodiment. However, if the result of the lottery determination is backed up, the decorative symbol 190 can be prepared to stop based on the information, which is advantageous in the symbol variation control. In other words, the effects of the above-described embodiment can be exhibited more significantly because the configuration of the above-described embodiment does not back up the game control state when the power is shut off on the sub-board 104 side.

(Modification 12)
