Description

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

  Conventionally, among various types of ball game machines, the so-called first type pachinko game machine, the lottery is performed in response to the ball entering the start opening provided on the game board, Depending on the result of the lottery, symbols are displayed in a variable manner. In other words, a plurality of symbols are displayed in a display area such as a liquid crystal display provided substantially in the center of the game board while the symbols are varied (hereinafter, such a display is referred to as “symbol variation” or “variable display”). This gaming machine is known to shift to a special game when a combination of symbols when a plurality of rows of symbol variations are stopped has a specific form. A special game is also called a jackpot, and a unit game involving the opening of a big prize opening provided on the game board is performed a plurality of times, and more prize balls can be obtained than a normal game (see, for example, Patent Document 1) ). The variable display of symbols in the display area is not only a variable display of multiple symbols, but the time of variable display is usually reduced in a state where it is a big hit if one more symbols are aligned, as in the so-called reach screen. For example, an effect is made to increase the player's expectation, such as making it longer.

  Among the gaming machines, there is also a special game that is advantageous to the player, which is called a so-called probability variation game (hereinafter also referred to as “probability variation”) or a variable time reduction game (hereinafter referred to as “short time”) after the special game is completed. There is something to migrate. When a special game has occurred and the winning stop symbol at that time is in a specific mode, the probability change is started after the special game ends. In the probability change, a lottery with a higher probability of winning than the normal probability state is performed, and a new special game is generated relatively early. Also, after the special game is over, time saving is started and continued for a predetermined period. During the short time, the ease of entering the starting port is enhanced, and the variation time of the symbol is generally shortened. When the transition to such a specific game occurs, a new special game is generated relatively early, and the player's sense of expectation is further enhanced.

  By the way, such a gaming machine generally indicates that the lottery result is a big win with the display of the winning symbol combination in a form in which three symbols are arranged, but the so-called third kind pachinko gaming machine For example, there are those that determine the jackpot by a two-stage lottery. When the first symbol indicating the first lottery result is stopped in the winning symbol combination, the right to win the jackpot is given, and then the second symbol indicating the second lottery result is stopped in the winning symbol combination. By doing this, the jackpot is confirmed. The two-stage lottery itself has the advantage of increasing the degree of design freedom with respect to the probability of transition to special games. However, since the display of the lottery result at the first stage does not represent the jackpot determination, there is a possibility that it is difficult for a player who is not used to a game involving such a staged lottery to understand the game.

  The inventors have come to the idea that such a problem can be solved by realizing such a staged appearance that the staged lottery process is secured internally and that the appearance is shown in one stage. It was. In addition, it has been recognized that a new gameability can be created by associating the winning probability of the stepwise lottery with the display process of the symbol variation.

  The present invention has been made in view of these problems, and the purpose of the present invention is to convey the confirmation of the transition to the player in an easy-to-understand manner in a type of game machine that determines the transition to a special game by a step-by-step lottery. The purpose is to effectively reflect the staged lottery results on the production side.

  In order to solve the above-described problems, a bullet ball gaming machine according to an aspect of the present invention includes a gaming board on which a gaming area is formed, a first start port provided at a predetermined position in the gaming area, and a first gaming area. A second start opening provided at a position different from the start opening, a special winning opening provided at a predetermined position in the game area and opened when the game state is changed from the normal game to the special game, and the first start The first lottery means for executing the first winning / losing lottery with the entrance to the mouth, and the transition to the special game when the first winning / notifying lottery is won and the entrance to the second starting port is received A second lottery means for executing a second winning / notifying lottery for determining whether or not to perform, a special game control means for executing a special game in response to a result of the second winning / notifying lottery being won, 1st display area in which the 1st symbol to show the result of 1 lottery lottery is displayed variably And a second display area in which the second symbol for indicating the result of the second winning / losing lottery is variably displayed, and a variation stopping mode from the start of change to the stop of the first symbol depending on the result of the first winning / losing lottery. The first symbol variation determining means for determining, the second symbol variation determining means for determining the variation stop mode from the variation start to the stop of the second symbol according to the result of the second winning / losing lottery, and the first symbol The first symbol is variably displayed in accordance with the variation stop mode, and whether or not the result of the first winning / losing lottery is true is indicated by the stop symbol, while the second symbol is determined in accordance with the variation stop mode determined for the second symbol. Is displayed as a symbol combination integrated with the first symbol, and the display control means for indicating whether or not the result of the second winning / losing lottery has been won by the stop symbol combination; When The combination of the probability that the result of the first winner / lottery wins after the end of the special game and the probability of the winner of the second winner / lottery win will be determined on the assumption that the result of the first winner / lottery winner will be the winner. And a probability determination unit.

  Here, a combination of a probability that the result of the first winning / losing lottery is won (also referred to as “first winning probability”) and a probability that the result of the second winning / notifying lottery is winning (also referred to as “second winning probability”). As for, the respective probabilities of the first winning probability and the second winning probability may be determined in advance and combined. Alternatively, a plurality of combination candidates of the first winning probability and the second winning probability may be set and any combination may be determined.

  According to this aspect, when the first winning / losing lottery is won (also referred to as “first winning”), the right to execute the second winning / losing lottery is obtained. The occurrence of the first hit is indicated by the stop symbol of the first symbol, but the stop symbol of the first symbol forms a partial display of the process indicating the result of the second winning / failing lottery, so Is unlikely to be recognized. On the other hand, if there is a ball entering the second starting port after the first symbol has been stopped in a winning manner, the second winning / losing lottery is executed. When the second winning / losing lottery is won (also referred to as “second winning”), the second symbol variation display is performed in such a manner that the stop symbol of the first symbol constitutes a part of the variation process. . That is, the second symbol is variably displayed as a symbol combination that is integral with the first symbol, and the stop symbol combination is displayed in a winning manner to indicate that the second symbol has occurred. When the result of the second winning / losing lottery is out, the stop symbol combination by the first symbol and the second symbol is displayed in a disengagement manner. For example, the “winning mode” is a mode in which the first symbol and the second symbol are aligned with the same type of symbol, and the “outside mode” is a mode in which the first symbol and the second symbol are not aligned with the same type of symbol. Also good. When the game is shifted to the special game due to the occurrence of the second hit, the special winning opening is opened. Therefore, the player can obtain more prize balls than usual by entering the special winning opening. The player comes to play a game for the purpose of the transition to the special game, that is, the second hit. When the game is shifted to the special game due to the occurrence of the second game, the combination of the first winning probability and the second winning probability is determined for the gaming state after the end of the special game. That is, if a high probability is set as the first winning probability, the second winning / losing lottery is likely to be executed, and if a high probability is set as the second winning probability, a second winning by the second winning / losing lottery occurs. It becomes easy. In other words, the combination of the first winning probability and the second winning probability determines the transition probability to the special game.

  According to this aspect, although the stepwise lottery is performed by the first winner / lottery lottery and the second winner / lottery lottery, a display in which the result display of the first winner / lottery lottery forms a part of the result display process of the second winner / lottery lottery is displayed. Made. For this reason, it is difficult for the player to recognize the first winning lottery and the second winning lottery individually, as if the presence / absence of transition to a special game is displayed as if one winning lottery and one symbol change. Be recognized. In other words, in a gaming machine with a specification that determines the transition to a special game by a step-by-step lottery, the determination of the transition can be easily communicated to the player. On the production side, the presence or absence of the transition to the special game is indicated by a series of symbol fluctuations by the first symbol and the second symbol. Occurrence becomes a condition for transition to special games. In other words, whether or not the symbol variation itself indicating whether or not to shift to the special game is displayed, and whether or not to display the shift to the special game when displayed, is a combination of the first winning probability and the second winning probability. Determined by. In other words, a new gameability is created in which a series of symbol variation patterns that indicate whether or not to shift to a special game is determined by stepwise lottery.

  Specifically, a plurality of first winning probabilities including a relatively high high probability and a relatively low low probability are set as probabilities that the first winning / losing lottery is won, while the second winning / winning lottery is winning. A plurality of second winning probabilities including a relatively high high probability and a relatively low low probability are set, and a combination of each of the plurality of first winning probabilities and each of the plurality of second winning probabilities is The probability selection means may be set as a plurality of probability selection targets, and the probability determination unit may execute a probability lottery that selects any one of the plurality of probability selection targets.

  When the first symbol variation determination means wins the first winning / losing lottery, the winning symbol indicating that the result of the second winning / losing lottery is winning if one more symbols are arranged as a stop mode of the first symbol The display of the reach state in which a plurality of symbols are stopped and displayed in combination is determined, and the second symbol variation determining means, when the second winning / losing lottery is won, the first symbol as the stop mode of the second symbol. You may decide to stop the display of one symbol after it is aligned.

  According to this aspect, the reach effect is displayed by the first hit, and the transition to the special game is confirmed by the symbols being gathered by the second hit. In other words, the first winning / losing lottery functions as a lottery for determining whether or not a reach effect appears, and the second winning / notifying lottery functions as a lottery for determining whether or not a big hit occurs from the reach state. . The conventional reach effect is positioned as one aspect of the variation pattern of the design indicating the result of the lottery, and the appearance probability of the reach effect is associated with the transition probability to the special game. There is no such correspondence. That is, the appearance probability of the reach effect is set as the first winning probability, while the transition probability to the special game based on the appearance of the reach effect is set as the second winning probability. In addition, since the combination of the first winning probability and the second winning probability is separately determined, the relationship between the appearance probability of the reach effect and the transition probability to the special game is not unique. In other words, a novel gameability that has not been achieved in the past is realized in that the appearance probability of reach production can be set separately from the probability of transition to special games.

  The display control means displays the stop display state of the first symbol after the first symbol is stopped and displayed in the reach state, and until the second winning lottery result is displayed by further displaying the second symbol. It may be held. In this way, the role of traditional reach production that shows winning if one more symbols are aligned is secured, and it is also possible to match with internal processing that shows the result of stepwise lottery it can.

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

  According to the present invention, in a type of game machine that determines the transition to a special game by a step-by-step lottery, the transfer confirmation is communicated to the player in an easy-to-understand manner, and the step-by-step lottery results are effectively used for production. It can be reflected.

The door 14 is attached to the front frame 12 so that it can be opened and closed by a hinge mechanism (not shown). The upper ball tray 15 has a mechanism for storing game balls, sending out the game balls to the launch rail, and extracting the game balls to the lower ball tray 16. The lower ball tray 16 has a mechanism for storing and extracting game balls. A speaker 18 is provided between the upper ball tray 15 and the lower ball tray 16, and a sound effect corresponding to the gaming state is output.

  The game board 50 has an out port 58, a special symbol display device 61, an effect display device 60, and a start winning port (hereinafter referred to as “start port”) 62 on a game area 52 defined by the outer rail 54 and the inner rail 56. , A center ornament 64, a grand prize opening 66, an operation opening 68, and a general prize opening 72. Furthermore, in the game area 52, a plurality of mechanisms such as a game nail and a windmill (not shown) are installed.

  The start opening 62 includes a start winning detection device 74 for detecting the entrance of a game ball, and a normal electric accessory solenoid 76 for expanding a normal electric accessory 65 that is an expansion mechanism of the start opening 62. , Function as a “second starter”. When the ordinary electric accessory 65 is expanded by the driving force of the ordinary electric accessory solenoid 76, the ease of entering the starting port 62 is increased. In the present embodiment, the opening time of the ordinary electric accessory 65 once is set to a fixed time (for example, about 4.5 seconds) regardless of whether it is in a short time or in a normal state. The start winning detection device 74 is a sensor that detects the entry of a game ball into the start port 62, and generates start win information indicating the winning at the time of entering.

  The general winning opening 72 includes a general winning detecting device 73 for detecting the entering of a game ball. The general winning detection device 73 is a sensor that detects the entry of a game ball into the general winning opening 72, and generates general winning information indicating the winning at the time of winning. The special winning opening 66 includes a winning detection device 78 for detecting the entry of a game ball and a special winning opening solenoid 80 for expanding the special winning opening 66. The winning detection device 78 is a sensor that detects the entry of a game ball into the big winning opening 66, and generates big winning opening winning information indicating the winning at the time of winning.

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

  The special symbol display device 61 and the normal symbol display device 59 provided on the right side of the game area 52 display the variation of the special symbol 192 and the variation of the normal symbol 194 on the respective screens. In addition, the effect display device 60 provided substantially in the center of the game area 52 displays the change of the effect image including the special symbol 192 linked to the special symbol 192 and the normal symbol 194 on the screen. Hereinafter, such display is referred to as “design variation” or “variation display”. Here, the special symbol 192 is a symbol corresponding to the result of the lottery performed when the game ball is dropped into the start port 62, and the symbol mode when the change display is stopped is determined to be the winning symbol. When the symbol is a symbol, the timing at which the stop symbol is displayed is the jackpot occurrence timing.

  The operation port 68 is provided at a position directly above the start port 62 and functions as a “first start port”. The operation port 68 includes an operation winning detection device 69. The operation winning detection device 69 is a sensor that detects the entry of a game ball into the operation port 68, and generates passing information indicating the passage when the game ball enters and passes through the sensor. The entry of the game ball into the operation port 68 triggers an open lottery to determine whether or not to expand the ordinary electric accessory 65 at the start port 62. In the present embodiment, as shown in the figure, when the ordinary electric accessory 65 is in the closed state, the entrance of the start port 62 is shielded by the operation port 68 and the game ball does not fall into the start port 62. However, in the modified example, it may not be completely shielded even in a normal time, and may be configured to rarely have a ball.

  The special symbol display device 61 is provided on the lower right side of the effect display device 60. The special symbol display device 61 is a display means composed of, for example, a 7-segment LED as shown in the figure. When a game ball enters the start port 62, a special symbol 192, which is a symbol indicating the result of the lottery determination, is variably displayed on the special symbol display device 61.

  The normal symbol display device 59 is provided on the lower right side of the effect display device 60 so as to line up with the special symbol display device 61. The normal symbol display device 59 is a display means composed of, for example, a 7-segment LED as shown in the figure. When a game ball enters the operation port 68, a normal symbol 194, which is a symbol indicating the result of the open lottery, is variably displayed on the normal symbol display device 59.

  The effect display device 60 variably displays a special symbol decorative symbol (hereinafter referred to as “special symbol decorative symbol”) 191 in conjunction with the special symbol 192 variation display, and the normal symbol 194 variation display. The liquid crystal display variably displays a decorative symbol for a normal symbol (hereinafter referred to as “decorative symbol for a general symbol”) 193 in an interlocking manner. In the following description, the special-purpose decorative symbol 191 and the general-purpose decorative symbol 193 are collectively referred to as “decorative symbol 190” as appropriate.

  The special symbol decorative symbol 191 is a symbol for visually displaying the result of the lottery determination shown by the special symbol 192, and is displayed in the center of the effect display device 60. On the other hand, the general-purpose decorative symbol 193 is a symbol for visually displaying the result of the success / failure lottery indicated by the normal symbol 194, and includes a pair of symbols arranged so as to sandwich the special-fitting decorative symbol 191. . However, as will be described later, in the production, the special symbol decorative pattern 191 is variably displayed as an integral symbol combination with the general symbol decorative symbol 193, and the presence or absence of jackpots as a whole of the decorative symbol 190, that is, transition to a special game Works to indicate presence or absence.

  The effect display device 60 displays, as the decorative symbol 190, for example, a plurality of rows of moving images of symbol variation simulating a slot machine game in the central area of the screen. The effect display device 60 is constituted by a liquid crystal display in this embodiment, but may be constituted by a mechanical rotating device such as a drum or other display means such as an LED. Note that the special symbol 192 and the normal symbol 194 do not necessarily have a role to play, so that they are displayed on a relatively simple display device composed of 7-segment LEDs. May be displayed.

  A center ornament 64 is provided around the effect display device 60. The center decoration 64 has functions such as a flow path of the game ball, protection of the effect display device 60, and decoration. On the lower right side of the effect display device 60, the special symbol display device 61 and the normal symbol display device 59 are arranged as described above. A special symbol holding lamp 20 is provided above the special symbol display device 61, and a general symbol holding lamp 22 is provided above the normal symbol display device 59. The special figure hold lamp 20 is composed of two lamps, and displays the number of hold of the winning lottery value according to the number of lighting or blinking of each lamp. The number of hold of the winning / failing lottery value in the special figure holding lamp 20 is the number of lottery results won to the start port 62 during the fluctuation of the special symbol 192 or during the execution of the special game, and the winning ball for which the symbol fluctuation has not been executed yet. Indicates the number of The regular figure holding lamp 22 is also composed of two lamps, and displays the number of holdings of normal symbol fluctuations depending on the number of lighting or blinking. 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 194, and indicates the number of normal symbol lotteries for which the fluctuation of the normal symbol 194 has not yet been executed. Furthermore, game effect lamps 90 are respectively provided above and below the effect display device 60. The operation button 82 is a button operated by the player to input a predetermined instruction to the gaming machine. The operation button 82 is provided on the outer wall surface near the upper ball tray 15.

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

  When the game ball falls into the operation port 68, the normal symbol display device 59 and the effect display device 60 variably display the normal symbol 194 and the general symbol decoration symbol 193. The variable display of the normal symbol 194 and the regular decorative symbol 193 is stopped after the elapse of the display time determined prior to the display. When the stop symbol of the normal symbol 194 and the decorative symbol for common symbol 193 is a symbol indicating a hit, the expansion of the normal electric accessory 65 is expanded and the ball can enter the start port 62. At this time, the decorative symbol 190 simulating a game of a slot machine takes a reach form that is a big hit if one more symbols are arranged.

  In this way, when the game ball is dropped in a state where the start port 62 is expanded, the special symbol 192 and the special symbol decoration symbol 191 are variably displayed on the special symbol display device 61 and the effect display device 60. The variable display of the special symbol 192 and the special symbol decoration symbol 191 is stopped after the elapse of the display time determined prior to the display. When the special symbol 192 and the decorative symbol 190 at the time of the stop are symbols indicating a big hit, the game shifts to a special game that is more advantageous to the player than the normal game, and the opening / closing operation of the big prize opening 66 is started. At this time, the decorative symbol 190 simulating a game of a slot machine takes a display mode in which three symbols are matched. In other words, in a state where the decorative pattern 193 for the ordinary figure is stopped in the reach mode, the decorative pattern 191 for the special figure is stopped and displayed with the same kind of the decorative pattern 193 for the ordinary figure. In the special game, the grand prize winning slot 66 is temporarily closed after being opened for about 30 seconds or after nine or more game balls are dropped. Such opening / closing of the big prize opening 66 is repeated a predetermined number of times, for example, 15 times.

  In the normal game after the end of the special game, a variable time shortening game (hereinafter referred to as “time reduction” as appropriate) that is one of the specific games is started. In the variation time shortening game, the variation time of the special symbol 192, the normal symbol 194, and the decorative symbol 190 is shortened from the normal time. The variation time of the special symbol 192, the normal symbol 194, and the decorative symbol 190 is returned to the original variation time after the variation display of the predetermined variation number is performed. When a special game occurs and the winning stop pattern at that time is in a specific mode, a probability variation game (hereinafter referred to as “probability change” as appropriate) that is one of the specific games after the special game ends Be started. In the probability variation game, a lottery with a higher win probability than the normal probability state is performed, and a new special game is generated relatively early.

  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 functions as a “first lottery means”, and when a game ball passes through the operation port 68, a random number value for determining a normal symbol is also referred to as a lottery value (also referred to as “normal figure lottery value”). ) To obtain a general drawing lottery. For example, the usual drawing lottery value is acquired from a value range from “0” to “511”. 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. In the common-use success / failure table referred to by the success / failure lottery means 112, the determination result of winning or losing is associated with the common-use lottery value, and the success / failure probability is determined according to the associated winning range setting. The success / failure lottery means 112 refers to a common-use success / failure table for determination of success / rejection with a low probability when setting a low probability, which will be described later, and a high-probability use / non-use table with a higher probability of winning than a low probability when setting a high probability. Refer to The result of the regular drawing lottery by the winning / not-lotting means 112 is variably displayed in the normal symbol display device 59 in the form of a normal symbol 194. In addition, the decorative symbol 193 for a general map that shows the determination result by the success / failure lottery means 112 is variably displayed on the effect display device 60.

  The success / failure lottery means 112 also functions as a “second lottery means”, and when the game ball enters the start port 62, whether or not to shift to a special game that is more advantageous to the player than the normal game? In order to determine whether or not, a random number value is acquired as a success / failure lottery value. For example, the success / failure lottery value is acquired from a value range from “0” to “65535”. The success / failure lottery means 112 holds a plurality of special figure success / rejection tables to be referred to in the success / failure determination. In the plurality of special figure success / failure tables, the determination result of winning or losing is associated with the success / failure lottery value, and the success / failure probability is determined according to the associated winning range setting. The success / failure lottery means 112 refers to a special figure success / rejection table for determination of success / failure based on a normal probability in normal times, and refers to a special-purpose success / failure table in which the probability of winning is higher than the normal probability when the probability changes. The success / failure lottery means 112 determines whether or not the success / failure lottery value is a win by referring to any of the plurality of special figure success / failure tables. The determination result by the success / failure lottery means 112 is variably displayed in a special symbol 192 form on the special symbol display device 61. The result of the determination by the success / failure lottery means 112 is variably displayed on the effect display device 60 as a symbol combination of the decorative symbol 190 including the special symbol decorative symbol 191 and the universal symbol decorative symbol 193.

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. When the stop symbol of the normal symbol 194 is a specific symbol, the opening / closing control means 124 expands the normal electric accessory 65 of the start port 62 for a predetermined time.

  The variation pattern determination means 115 selects any variation pattern from a plurality of types of variation patterns according to the result of the success / failure lottery. The variation pattern determining means 115 holds a pattern selection table to be referred to in order to determine the variation pattern. The symbol determination unit 114 sends data indicating the determined variation pattern to the main display control unit 118, the symbol mode determination unit 131, and the effect determination unit 132. The variation pattern determining means 115 stores a plurality of types of variation patterns in which variation modes from the variation start to the stop when the special symbol 192 is displayed in a variable manner are defined. Each variation pattern has a variation display time for each pattern as an end condition of the symbol variation, and the variation of the special symbol 192 and the special symbol decoration symbol 191 is stopped when the variation display time elapses. The variation pattern determining means 115 also stores a plurality of types of variation patterns in which variation modes from the variation start to the stop when the normal symbol 194 is displayed in a variable manner are defined. For each variation pattern, a variation display time is defined for each pattern as an end condition of the symbol variation, and when the variation display time elapses, the variation of the normal symbol 194 and the ordinary symbol decoration symbol 193 is stopped.

  The hold control means 116 holds the winning / losing lottery value acquired by the winning / failing lottery means 112 as a holding ball. The success / failure lottery value is accumulated until the number of reserves reaches a predetermined upper limit (four in this embodiment). The hold control means 116 also holds the usual lottery value acquired by the success / failure lottery means 112 as a hold ball. The usual lottery value is accumulated until the number of holds reaches a predetermined upper limit (four in this embodiment).

  The main display control unit 118 causes the special symbol display device 61 to display the result of the success / failure lottery performed by the success / failure lottery unit 112 as a variation display of the special symbol 192 according to the variation pattern determined by the symbol determination unit 114. The main display control means 118 transmits a change start command and a change stop command for the special symbol to the effect display control means 134 at the timing to start and stop the fluctuation display of the special symbol 192. Thereby, the fluctuation display of the special symbol 192 by the main display control means 118 and the fluctuation display of the special symbol decoration symbol 191 by the effect display control means 134 are synchronized, and the interlock is maintained.

  The main display control means 118 also causes the normal symbol display device 59 to display the result of the general symbol lottery by the success / failure lottery means 112 as a fluctuation display of the normal symbol 194 according to the fluctuation pattern determined by the symbol determination means 114. The main display control means 118 transmits a normal symbol fluctuation start command and a fluctuation stop command to the effect display control means 134 at the timing of starting and stopping the fluctuation display of the normal symbol 194. As a result, the fluctuation display of the normal symbol 194 by the main display control means 118 and the fluctuation display of the decorative pattern 193 for general symbols by the effect display control means 134 are synchronized, and the linkage is maintained.

  The special game control means 120 controls the execution process of the special game when the result of the lottery determination by the success / failure lottery means 112 is a win. The special game is a game in which the opening / closing operation of the special winning opening 66 is continuously performed a plurality of times, and is configured by a plurality of unit games with one opening / closing as a unit. The unit game is repeated up to 15 times, for example, and the grand prize opening 66 is opened for about 30 seconds in one unit game. If the number of continuations of the unit game has not reached the upper limit number, the special game control means 120 starts the next unit game after the end of the current unit game. When the upper limit number of unit games is exhausted, the special game is terminated.

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

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

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

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

  The effect determining means 132 determines the variable effect pattern according to the respective stop patterns of the special symbol 192 and the normal symbol 194 and the variable patterns of the special symbol 192 and the normal symbol 194 as a result of the lottery by the success / failure lottery means 112. The effect determining unit 132 holds a pattern table to be referred to in order to determine the variation effect pattern, and selects an effect pattern having a display time corresponding to each variation pattern of the special symbol 192 and the normal symbol 194. The effect determining means 132 sends information on the determined variation effect pattern to the effect display control means 134.

  The symbol pattern determining means 131 determines the combination of stop symbols of the decorative symbol 190 and the arrangement thereof as a result of the lottery by the success / failure lottery means 112, the special symbols 192 and the normal symbols 194, the special symbols 192 and the normal symbols 194, respectively. It is determined according to the variation pattern and the variation effect pattern of the decorative design 190. The symbol form determination unit 131 transmits information indicating the determined combination of stop symbols to the effect display control unit 134. The symbol form determining means 131 holds a symbol range table to be referred to in order to determine the stop symbol of the decorative symbol 190.

  The stop symbol of the decorative symbol 190 is formed as a combination of three symbols including a special symbol decorative symbol 191 and a general symbol decorative symbol 193. For example, when the determination result by the winning / failing lottery means 112 indicates a shift to a special game. A combination of three symbols such as “777” and “111” is selected. In the case where the determination result by the success / failure lottery means 112 indicates that the game does not shift to the special game, a combination that does not have three symbols such as “312” and “946” is selected.

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

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

  The effect display control means 134 variably displays the effect image including the decorative pattern 190 on the effect display device 60 according to the selected variation effect pattern data as a result of the success / failure lottery by the success / failure lottery means 112.

  The effect display control means 134 causes the effect display device 60 to display the notice effect according to the selected notice effect pattern when the effect determining means 132 determines to display the notice effect. The effect display control means 134 further controls effect processing such as lighting and extinguishing of the game effect lamp 90 and sound output from the speaker 18.

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

Next, specific contents of the effect display control executed in the present embodiment will be described.
FIG. 4 is a diagram illustrating an example of a screen displayed in the process of changing the symbol indicating the result of the lottery determination. FIGS. 4A to 4D show the variation display process.

  In the display area 195 of the effect display device 60, the decorative symbol 190 is variably displayed in a substantially central region, and various effect images such as a notice effect are displayed so as to be superimposed on the variable display of the decorative symbol 190. The As described above, the decorative symbol 190 includes three symbols including the central special symbol decorative symbol 191 corresponding to the special symbol 192 and the left and right common symbol decorative symbols 193 corresponding to the normal symbol 194. . Each symbol is displayed as a part of a virtual symbol string in which seven stop symbol candidates composed of numbers from “1” to “7” are continuously arranged.

  In the present embodiment, when the result of the general drawing lottery is a win, the start port 62 can enter the ball, and the special symbol 192 is displayed in a variable manner only after the ball is entered. That is, the special symbol 192 does not start to change until the normal symbol 194 is stopped at the winning symbol. For this reason, if it is applied to the decorative symbol 190, the central special symbol decorative symbol 191 does not start to change until the left and right universal symbol decorative symbols 193 are stopped in the hit state, and the player feels uncomfortable. There is a risk of giving. This is because, in a general pachinko gaming machine, the decorative symbols take a form in which three symbols start to change at the same time and are sequentially stopped.

  Therefore, in this embodiment, in order not to cause such a sense of incongruity, as shown in FIGS. 6A and 6B, the special-purpose decorative pattern 191 is displayed until the universal decorative pattern 193 stops at the winning design. An effect is made to cover and hide. In other words, if the result of the regular drawing lottery is out of order, the special symbol decorative symbol 191 cannot start changing, and therefore the special symbol decorative symbol 191 is not displayed. In this embodiment, the fact that the result of the regular drawing lottery is a win is displayed in a reach effect that is a big win if one more symbols are arranged. For this reason, if the result of the lottery drawing is out of place, the left and right common symbol decorative symbols 193 are stopped at different symbols, and only the symbol variation of the common symbol decorative symbol 193 is continued as long as the symbol continues to be removed. Is repeated.

  When the result of the general drawing lottery is won, as shown in FIG. 6C, the left and right general-purpose decorative symbols 193 are stopped in a reach manner in which they become the same type of symbols (“7” in the illustrated example). Then, the central special symbol decorative pattern 191 appears, and is variably displayed every time there is a ball entering the start port 62. That is, when the general-purpose decorative symbol 193 is hit and stopped at the symbol, the start port 62 is opened for a predetermined time, and a game ball can be entered. The special symbol decorative symbol 191 is variably displayed for the variation time of the special symbol 192 corresponding to the number of balls entered at the time of opening. The special symbol decorative pattern 191 is basically repeatedly changed according to the number of reserved balls at the time of opening, but when the reserved ball includes a hit, the change display with a hit change indicating the hit is displayed. Will be interrupted and will shift to special games. FIG. 6D shows a state in which three symbols of the decorative symbol 190 are aligned with the result of the winning / failing lottery.

  FIG. 5 is a data structure diagram of a special figure success / failure table used to determine whether or not to shift to a special game. FIG. 4A shows a normal table used when the gaming state is in the normal state, and FIG. 4B shows a probability change table used when the probability is changed.

  The success / failure lottery means 112 acquires the success / failure lottery value from the range of “0 to 65535” prior to the determination of success / failure. Then, the normal table 210 or the probability variation table 212 is referred to depending on whether or not the gaming state is in the probability variation state. In the example shown in the figure, the winning probability based on the normal table 210 is about 1/20, whereas the winning probability based on the probability variation table 212 is about 1/10. It is set to occur. However, since this success / failure lottery is executed on the assumption that the normal drawing lottery is won, the probability is not directly equal to the probability of transition to the special game.

  FIG. 6 is a data structure diagram of the universal map success / failure table used in the general map lottery. FIG. 5A shows a high accuracy table used when the high probability setting is set, and FIG. 5B shows a low accuracy table used when the low probability setting is set.

  The success / failure lottery means 112 acquires the general drawing lottery value from the range of “0 to 511” prior to the general drawing lottery. Then, the low probability table 220 or the high probability table 222 is referred to according to the current probability setting state. In the illustrated example, the winning probability based on the low probability table 220 is about 1/10, whereas the winning probability based on the high probability table 222 is about 1/2. Is set to have a high probability of winning. The “win” here is a win for the regular drawing lottery, and corresponds to the probability that a reach effect is produced by the decorative symbol for common drawing 193.

  In other words, the probability that a reach effect will be made is determined depending on which of the common map success / failure tables is selected, and the probability of jackpot occurrence depends on which special table's success / failure table is selected on the assumption that the reach effect has been made. It will be decided.

  7 and 8 are data structure diagrams of the symbol determination table used when determining the normal symbol and the decorative symbol for ordinary symbols. For convenience of explanation, the symbol determination table is a combination of a symbol range table for determining a normal symbol and a general symbol design determination table for determining a decorative symbol for general symbols. However, each table may be provided individually.

  As shown in FIG. 7, the symbol determination unit 114 acquires a symbol determination lottery value from a range of “0 to 255” prior to determination of the stop symbol of the normal symbol. In the present embodiment, “1”, “3”, “5”, “7”, “−” are set to be selectable as the stop symbols of the normal symbols. In the example shown in the drawing, when the result of the general drawing lottery is a win, one of the symbols “1”, “3”, “5”, “7” is selected, and “−” is selected when the result is off. .

  The symbol form determining unit 131 selects either the normal symbol determined by the symbol determining unit 114 or a plurality of general-purpose figure determination tables in accordance with the current game state, and selects the decorative symbol for the general symbol by lottery. decide. Here, in the “current game state” shown in the figure, “A” indicates a probability variation state and a high probability setting state, “B” indicates a probability variation state and a low probability setting state, and “C” indicates a normal state and a high probability state. A setting state is indicated, and “D” indicates a normal state and a low probability setting state. As described above, the probability variation table is referred to in the probability variation state during the lottery determination, and the normal table is referred to in the normal state. Further, in the normal lottery, the high probability table is referred to in the high probability setting state, and the low probability table is referred to in the low probability setting state. For this reason, a player's profit state will differ greatly with the combination of each game state.

  That is, when “1” is determined as the normal symbol, when the gaming state is “A”, “B”, “C”, “D”, the general-purpose figure determination tables “1-A”, “ “1-B”, “1-C”, and “1-D” are selected. The same applies to the normal symbols “3”, “5”, and “7”. The symbol form determination means 131 acquires the symbol lottery value from the range of “0 to 127” prior to the determination of the stop symbol (that is, the reach symbol) of the decorative symbol for general symbols. Then, the decorative pattern for the general drawing is determined with reference to the selected general drawing design determination table.

  As shown in FIG. 8 (a), in the general-purpose figure determination table “1-A”, the selection probabilities “3” and “7” are set to be considerably high as the general-purpose decorative symbols. In other words, if the reach effect by “3” or “7” is frequently displayed, the player can infer that the current gaming state is a probabilistic state and a high probability setting state. That is, it is easy to win the usual lottery, and it is highly possible that the winning lottery will be a big win, that is, it can be recognized that the total probability of transition to the special game is the highest. In addition, since “2” and “6” are excluded from the selection target as the decorative symbols for the general illustration, when the reach effect is displayed by either of the symbols, the player is in the best current gaming state. It can be recognized that it is not in a state.

  As shown in FIG. 8B, in the universal design determination table “1-B”, all symbols are selected as the decorative symbols for universal symbols, but relatively odd numbers are selected. The probability is set high. In other words, the appearance frequency of reach production is not high, but when it appears, if the odd symbol display frequency is high, the player guesses that the current gaming state is in the low probability setting state but is in the probability variation state can do. That is, although the possibility that the reach effect is displayed is low, it can be recognized that if the reach effect is displayed, it is highly likely that it will be a big hit.

  As shown in FIG. 8 (c), in the universal design determination table “1-C”, all symbols are selected as the decorative symbols for universal drawings, but relatively even numbers are selected. The probability is high, and in particular, the selection probability of “4” is set high. In other words, if the reach symbol by “4” is frequently displayed, the player is not in a probabilistic state although the current gaming state is a high probability setting state, that is, the reach effect is easily displayed, but the jackpot It can be recognized that the possibility is low.

  As shown in FIG. 8D, in the universal design determination table “1-D”, all symbols are selected as decorative symbols for universal illustration, but relatively even numbers are selected. The probability is high, and the difference in selection probability between even symbols is set to be small. In other words, if the appearance frequency of the reach effect is low and the appearance frequency of the even symbols is high when it appears, the player can infer that the current gaming state is in the normal state and the low probability setting state. That is, it can be recognized that the transition probability to the special game is the lowest as a total.

  In addition, although not shown in figure for the illustration drawing determination tables “3-A” to “3-D”, “5-A” to “5-D”, and “7-A” to “7-D”, The settings are almost the same as “1-A” to “1-D”, respectively. When the regular drawing lottery is won, the opening time of the start port 62 is the normal state or specific game regardless of whether the normal symbol is “1”, “3”, “5”, “7” Regardless of the state (short time), it is set to 4.5 seconds.

  On the other hand, if the result of the general drawing lottery is lost and “-” is displayed as the normal symbol, the general-purpose drawing determination table “X” is selected. In this general-purpose figure determination table “X”, a plurality of combinations of decorative figures for general-purpose figures that do not reach the reach are set. The symbol form determination means 131 acquires the symbol lottery value from the range of “0 to 127” prior to the determination of the stop symbol (that is, the symbol that does not constitute the reach aspect) of the decorative symbol for regular symbols. Then, the decorative pattern for the general drawing is determined with reference to the selected general drawing design determination table.

  FIG. 9 is a data structure diagram of a symbol determination table used when determining a special symbol and a special symbol decoration symbol. For convenience of explanation, the symbol determination table is a combination of a symbol range table for determining a special symbol and a special symbol design determination table for determining a special symbol decoration symbol. However, each table may be provided individually.

  The symbol determination means 114 acquires a symbol determination lottery value from a range of “0 to 255” prior to determination of a special symbol stop symbol. In the present embodiment, “1”, “3”, “5”, “7”, “−” are set to be selectable as the stop symbols of the special symbols. In the example shown in the figure, when the result of the lottery is a win, one of the symbols “1”, “3”, “5”, and “7” is selected, and “−” is selected when the result is off. If the result of the lottery is a win, the gaming state after the special technique is determined according to the selected special symbol. In the example shown in the figure, when “1” is selected as the special symbol, the state “A”: the probability variation state and the high probability setting state, and when “3” is selected, the state “B”: the probability variation state and the low probability setting. When “5” is selected, the state “C” is shifted to the normal state and the high probability setting state, and when “7” is selected, the state “D” is shifted to the normal state and the low probability setting state. It will be.

  When the result of the lottery is a win, the symbol pattern determining means 131 selects a symbol of the same kind as the previously determined decorative symbol for reach (reach symbol) as the special symbol decorative symbol, and the three symbols constituting the decorative symbol are selected. Make sure the pattern is aligned. Thereby, the player is shown the occurrence of a jackpot. That is, in general pachinko gaming machines, decorative symbols are determined corresponding to special symbols. In this embodiment, decorative symbols are divided into decorative symbols for special symbols and decorative symbols for special symbols. After the decorative pattern for the symbol is determined, the decorative symbol for the special symbol is determined. Because of such a determination process, a special-purpose decorative symbol is set according to the general-purpose decorative symbol. For this reason, in the present embodiment, there is no effect that suggests whether or not the probability change transition is made after the special game, depending on the type of the number of the decorative symbol.

  In the present embodiment, whether or not there is a certain change is suggested by the colors of the three symbols constituting the decorative symbol (not shown). Specifically, when the probability change transition is not performed, the color of the design is left as normal black, and when the probability change transition is performed, the symbol color is changed to red. In this embodiment, only the presence / absence of probability change is suggested as the gaming state after the special game, but the probability setting state of the normal drawing lottery may also be suggested. For example, the state is indicated by displaying red when moving to the state “A”, orange when moving to “B”, blue when moving to “C”, and black when moving to “D”. May be performed. In the modified example, the game state after the special game is not suggested by the color of the decorative design as described above, but may be suggested by the difference in the shape (font) of the design. Alternatively, during the jackpot presentation after the transition to the special game, the game state after the special game may be explicitly notified by display of a character string or sound.

  When the result of the lottery determination is out of place, the symbol pattern determining means 131 selects a symbol of a different type from the already-decorated decorative symbol for reach (reach symbol) as a special symbol decorative symbol 3. Make sure that no two symbols are aligned. Thereby, it is shown that a big hit has not occurred for the player, that is, it is out of place. Specifically, seven stop symbol candidates “1” to “7” are prepared as symbol selection candidates, and six stop symbol candidates other than the symbols determined as the decorative symbols for regular symbols are prepared. Either is selected by lottery.

  FIG. 10 is a timing chart showing an example of a symbol variation display process. In the same figure, from the top, the fluctuations of the normal symbol and the decorative symbol for the normal symbol, and the fluctuations of the special symbol and the decorative symbol for the special symbol are shown. The horizontal axis represents the passage of time.

  In the example shown in the drawing, the variation of the normal symbol is started by entering the operation port 68, and the normal drawing lottery is won at the time t1 (indicated as “per normal drawing”). For this reason, after the normal symbol hit variation is performed, the ordinary electric accessory 65 is opened. It should be noted that the decorative symbols for the general symbols are also displayed so as to be synchronized with the variations of the normal symbols. At this time, since there were five or more balls in the starting port 62 during the opening period (for example, 4.5 seconds) of the ordinary electric accessory 65, the variation of the special symbol corresponding to the first ball at time t2 ( Special symbol fluctuations) are started, and special symbol fluctuations corresponding to the reserved balls that have been reserved up to the upper limit (four) are sequentially displayed.

  In the present embodiment, the variation time of the special symbol is fixed (for example, 5 seconds), and is set longer than the opening period of the ordinary electric accessory 65. For this reason, the special symbol does not fluctuate a plurality of times during the opening period. In other words, the fluctuation time of the special symbol that accompanies the common figure will be within the time of five fluctuations at the maximum. Therefore, in this embodiment, at least the time corresponding to the five variations of the special symbol is secured as the fixed display stop time of the decorative symbol for the special symbol that exhibits the reach mode, and the special symbol ornament is changed before the variation of the special symbol decorative symbol stops. It avoids the inconvenience that the variation of the symbol is resumed. This is because the player feels uncomfortable if the left and right symbols resume fluctuation before the central symbol stops despite reaching the reach state.

  However, since it is not always possible to enter the start port 62 immediately after the ordinary electric accessory 65 is opened, at least the design time α during which the entry is expected after the opening is included as an allowance for the stop display fixed time. I have to. In other words, the stop display fixed time Twait for the decorative symbol for ordinary symbols is set as a time (Twait = Tset + α) obtained by adding the margin value α to the set time Tset for five variations of the special symbol. In the example shown in the drawing, the winning lottery was not won during the stop display fixed time Twait, so the special symbol variation is continued for five variations and stopped at time t3. Then, at time t4 when the stop display fixed time Twait has elapsed, the normal symbol stop state is released, and the fluctuation starts again.

  After that, since the normal drawing lottery is won again at time t5, the normal electric accessory 65 is released after the normal symbol hit variation is performed. Since there was a ball entering the start port 62 during the opening period of the ordinary electric accessory 65, a special symbol variation corresponding to the first ball is started at time t6. In the example shown in the drawing, the winning lottery corresponding to the first holding ball obtained during the opening period of the ordinary electric utility item 65 is won (indicated as “per special figure”), so that the hit fluctuation varies from time t7 to t8. After that, the jackpot production has started. Note that, at time t9 after the elapse of the fixed display stop time Twait for the decorative symbols for ordinary symbols, the common symbol has occurred again, but since the special game is in progress, the variation of the special symbols has not started. During the special game, only the normal symbol is displayed in a variable manner, and the variable symbol display processing for the general symbol decorative symbol, the special symbol, and the special symbol decorative symbol is cancelled.

  FIG. 11 is a flowchart showing a basic operation process in the pachinko gaming machine. First, processing is performed when the game ball has won the start port 62, the general winning port 72, the big winning port 66, or when the game ball has passed through the operation port 68 (S10). (N in S12), control processing for normal games such as winning / failing lottery is executed (S14), and if a special game is in progress (Y in S12), control processing for special game is executed (S16), from S10 to S16 In step S18, a prize ball payout corresponding to various winnings is processed.

FIG. 12 is a flowchart showing in detail the normal game control process of S14 in FIG.
In the normal game control process, the normal symbol process is first executed (S20), and then the special symbol process is executed (S22).

  FIG. 13 is a flowchart showing in detail the normal symbol processing of S20 in FIG. If the regular drawing lottery value is held (Y of S100), the normal lottery means 112 is not normally displayed if the normal symbol is not variably displayed (N of S102) and is not fixed (N of S103). As a drawing lottery, a success / failure determination process is executed (S104). That is, the success / failure lottery means 112 reads the ordinary drawing lottery value and determines the success / failure based on the ordinary drawing lottery value. Subsequently, a symbol variation determination process is performed for determining a variation stop mode from the variation start to the stop of the normal symbol and the decorative symbol for ordinary symbols in accordance with the determination result (S105). Then, the variation display of the normal symbols and the decorative symbols for ordinary symbols is started (S110).

  If the standard drawing lottery value is not held in S100 (N in S100), the processing from S102 to S110 is skipped, and if the normal symbol is being displayed in a variable manner in S102 (Y in S102), S103 To S110 are skipped. If the normal symbol is fixed at S103 (Y in S103), the processing from S104 to S110 is skipped.

  Subsequently, if the normal symbol variation display has been started (Y in S112), the variation display of the normal symbol and the regular symbol decoration symbol is processed (S114). When the change display stop timing is reached (Y of S116), the normal symbol and the decorative symbol for normal display during the change display are stopped and displayed (S118). If the stop symbol of the normal symbol is the hit mode, that is, if the stop symbol of the decorative symbol for the normal symbol is the reach mode (Y in S120), the start port 62 is opened by driving the normal electric accessory 65 (S122). If the stop symbol is not a winning mode (N of S120), the process of S122 is skipped. If it is before the fluctuation time has elapsed (N in S116), the processing from S118 to S122 is skipped. When the variable display is not started in S112 (N of S112), the processes from S114 to S122 are skipped.

FIG. 14 is a flowchart showing in detail the symbol variation determination process of S105 in FIG.
The symbol determination means 114 determines the stop symbol of the normal symbol based on the determination result of the normal lottery (S130), and selects the variation pattern of the normal symbol (S132). The symbol form determining means 131 determines a decorative symbol for a general symbol based on the determination result, the normal symbol and the current gaming state (S134), and determines a variation pattern of the decorative symbol for a general symbol (S136).

FIG. 15 is a flowchart showing in detail the special symbol processing of S22 in FIG.
If the winning lottery value is held (Y in S140) and the special symbol is not being variably displayed (N in S142), the winning lottery means 112 executes a pass / fail determination process as a winning lottery (S144). 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. Subsequently, a symbol variation determination process for determining a variation stop mode from the variation start to the stop of the special symbol and the special symbol decorative symbol is executed according to the determination result (S145). Then, the variation display of the special symbol and the special symbol decoration symbol is started (S150).

  If the winning or failing lottery value is not held in S140 (N of S140), the processing from S142 to S150 is skipped, and if the special symbol is being displayed in a variable manner in S142 (Y of S142), from S144 The process of S150 is skipped.

  Subsequently, if the variation display of the special symbol has been started (Y in S152), the variation display of the special symbol and the special symbol decoration symbol is processed (S154). When the stop timing of the variable display is reached (Y in S156), the special symbol and the special decorative symbol for variable display are stopped and displayed (S158). If the result of the lottery is a win (Y in S160), the game is shifted to a special game (S162). If the result of the lottery decision is out (N in S160), the process in S162 is skipped. If it is before the fluctuation time has elapsed (N in S156), the processing from S158 to S162 is skipped. When the variable display is not started in S152 (N in S152), the processing from S154 to S162 is skipped.

FIG. 16 is a flowchart showing in detail the symbol variation determination process of S145 in FIG.
The symbol determining means 114 determines a stop symbol of the special symbol based on the result of the determination of winning / failing in the lottery determination (S170), and selects a variation pattern of the special symbol (S172). The symbol form determining means 131 executes a special symbol decorative symbol determination process based on the determination result and the universal decorative symbol (S174), and determines the variation pattern of the special symbol decorative symbol (S176).

FIG. 17 is a flowchart showing in detail the special symbol decoration design determining process of S174 in FIG.
When the result of the lottery determination is a win (Y in S180), the symbol form determining means 131 determines the same symbol as the ornamental symbol for ordinary symbols as the ornamental symbol for special symbol (S182). At this time, since the design of the reach mode has already been stopped as the decorative symbol for the general symbol, setting the same symbol as that makes it possible to produce an effect that aligns the three symbols of the decorative symbol, and the jackpot suggestion display is possible Become. On the other hand, if the result of the lottery determination is not good (N in S180), a lottery for selecting a symbol different from the decorative symbol for ordinary drawing is executed to determine the special symbol decorative symbol (S184). At this time, the reach design symbol is stopped and displayed as a decorative symbol for general symbols, but by setting a different symbol from that, it is possible to produce an effect display in which the central symbol of the decorative symbol is not aligned, and it is possible to display a suggestion of detachment It becomes.

FIG. 18 is a flowchart showing in detail the special game control process of S16 in FIG.
First, if the big prize opening 66 has not been opened (N in S70), the production display control means 134 starts the special game production process (S72), and the open / close control means 124 opens the special prize opening 66 (S74). ). If the big winning opening 66 has been opened, S72 and S74 are skipped (Y in S70). When the predetermined opening time has elapsed since the grand prize opening 66 was opened (Y in S76), or the opening time has not elapsed (N in S76), there are nine or more game balls to the big winning opening 66 When the player has entered the ball (Y in S78), the opening / closing control means 124 closes the special winning opening 66 (S80). If the opening time has not elapsed (N in S76) and the number of balls entered into the grand prize winning opening 66 has not reached nine or more (N in S78), the processing after S80 is skipped and the flow of S16 Exit.

  If the number of rounds of the unit game has reached 15 after closing the special winning opening 66 in S80 (Y in S82), the effect display control means 134 ends the effect processing of the special game (S84), and the special game control means 120 ends the special game (S86). The specific game execution means 122 shifts the game state to the specific game and starts execution of a short time (S88). Further, if the special game to be ended is accompanied by a probability change transition, the probability change is executed. If the number of rounds has not reached the final round (N of S82), 1 is added to the number of rounds and the flow of S16 is terminated (S90).

  As described above, in the pachinko gaming machine 10 according to the present embodiment, when the normal drawing lottery is won, it is possible to enter the starting port 62, and the lottery determination is executed on the condition of the entry. A two-stage lottery is performed. On the production side, decorative symbols are provided not only for the special symbol 192 but also for the normal symbol 194. Then, the special symbol decorative symbol 191 of the special symbol 192 and the normal symbol decorative symbol 193 of the normal symbol 194 are variably displayed as an integrated symbol combination constituting the decorative symbol 190, and the jackpot is generated by the stop symbol combination. Display whether or not. That is, when the common drawing lottery is won, a reach effect is produced by the left and right common drawing decorative symbols 193, and when the central special drawing decorative symbols 191 are aligned, the occurrence of a big hit is indicated. That is, since the result of the normal drawing forms a part of the result display process of the winning lottery, it is difficult for the player to recognize the first stage lottery. In other words, although it is a two-stage lottery, it is difficult for the player to recognize the first-stage general drawing lottery and the second-stage lottery lottery individually, as if one win-win lottery and one symbol variation The presence or absence of transition to a special game is recognized as being displayed. As a result, it is possible to easily convey the occurrence of the jackpot due to the two-stage lottery to the player who is used to the gaming machine having the specification that determines the jackpot by the one-stage lottery.

  In addition, on the production side, the presence or absence of transition to special games is indicated by a series of symbol fluctuations by the decorative symbol for special drawing and the decorative symbol for special drawing. Occurrence of winning by lottery is a condition for shifting to special games. In other words, whether or not a special symbol decoration symbol indicating whether or not to shift to a special game is displayed, and whether or not a special game transition is displayed when it is displayed, determines whether or not the winning probability (high probability) (A set state or a low probability set state) and a winning probability (probability variation state or normal state) of the winning / failing lottery. In other words, a new game is created in which a series of symbol variation patterns that indicate whether or not to shift to a special game is determined by a two-stage lottery. Reach effects are displayed by winning the lottery, and the symbols are aligned and the transition to the special game is confirmed by winning the lottery. That is, in this embodiment, the probability of reaching the reach effect is set as the probability setting state of the normal drawing lottery, while the probability of transition to the special game based on the appearance of the reach effect is set as the presence or absence of the probability change state. Yes. An innovative gameplay that has never existed in the past is realized in that the appearance probability of reach production can be set in a state separated from the probability of transition to special games.

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

[Modification 1]
FIG. 19 is a timing chart illustrating an example of a symbol variation display process according to the modification. In the figure, from the top, fluctuations in normal symbols and ordinary decorative patterns, changes in special symbols, and variations in special decorative symbols are shown. The horizontal axis represents the passage of time.

  In the above embodiment, until the decorative symbols for the left and right are stopped at the winning symbol so that the player does not feel uncomfortable by the left and right symbols fluctuating with the central symbol of the decorative symbol stopped. In the example shown in FIG. 4, the central special design decorative pattern is covered and hidden. This is based on the premise that the variation stop mode of both symbols is matched because the decorative symbol for special symbol is positioned so as to show the variation of the special symbol in an effect. In this modification, the correspondence relationship is relaxed, and the special symbol decorative symbol is displayed in an exceptionally variable manner even during the normal symbol variation period in which the special symbol does not vary.

  In other words, in the illustrated example, even before the special symbol variation display is started at time t2 or t6, the special symbol decoration symbol is varied in accordance with the variation of the ordinary symbol decoration symbol (see the alternate long and short dash line). By doing so, it is not necessary to cover the central special symbol decorative symbol as shown in FIGS. 4A and 4B, and the decorative symbol can be variably displayed in a more natural form. become. Even in such a case, in order to ensure the original position that the special symbol decorative symbol is a special symbol decorative symbol, the variation pattern of the special symbol decorative symbol is made different depending on the presence or absence of the special symbol variation. Also good. For example, when a special symbol changes, the special symbol decorative symbol is changed at high speed according to the special symbol change, while when the special symbol is stopped, the special symbol decorative symbol is changed at low speed or slightly moved. It may be possible.

[Modification 2]
FIG. 20 is a timing chart illustrating an example of a symbol variation display process according to another modification. In the same figure, from the top, the fluctuations of the normal symbol and the decorative symbol for the normal symbol, and the fluctuations of the special symbol and the decorative symbol for the special symbol are shown. The horizontal axis represents the passage of time.

  In the above embodiment, it is assumed that even when a plurality of game balls enter when the start port 62 is opened, the result of the individual lottery determination is determined every time the variation starts. That is, the variation pattern determining unit 115 sends the variation time information to the symbol form determining unit 131 for each variation of the special symbol. For this reason, the symbol mode determining means 131 cannot calculate the total symbol variation time of the special symbol while the normal symbol is stopped. Even in such a specification, a sufficient stoppage time is set for the decorative pattern for the general figure so that the fluctuation of the decorative pattern for the special figure does not resume during the change of the decorative pattern for the special figure. That is, a special method is adopted in which the time for changing the special symbol is fixed, and the fixed display stop time (Twait) for the decorative symbol for the general symbol is set assuming the maximum number of reserved balls (four).

  In the present modification, the total variation time of the special symbol is accurately calculated by so-called prefetching, and accordingly, the stop display fixed time of the decorative symbol for general symbols is appropriately set. In other words, in the illustrated example, the success / failure lottery means 112 executes the success / failure determination based on the success / failure lottery value as a pre-determination process even at the time of entry after the start port 62 is opened, and the special symbol variation time information included in the determination result Are sequentially transmitted to the symbol form determining means 131. As a result, the symbol pattern determining means 131 can calculate the total variation time of the special symbol corresponding to the number of reserved balls acquired during the opening period of the start port 62. More specifically, since the winning / failing lottery value is not reserved for the special symbol of the first variation, the variation time can not be easily calculated, but for the second and subsequent variations, the varying time can be specified based on the retained lottery value retained. Therefore, the total variation time of the special symbol can be calculated.

  Therefore, the symbol form determining means 131 uses the sum of the variation times T1, T2, T3, and T4 of the special symbols corresponding to the second and subsequent variation of the reserved ball as the stop display fixed time Twait1 (= T1 + T2 + T3 + T4) Set as. In other words, when the normal symbol and the decorative symbol for ordinary symbols are stopped after the winning variation by the normal lottery, the symbol pattern determining unit 131 first waits until the special symbol variation started when the start port 62 is opened is stopped. The stop state is maintained until Twait01 elapses. Then, the stop display fixed time Twait1 is calculated at the timing when the ordinary electric accessory 65 is closed, and the stopped state is maintained until the stop display fixed time Twait1 elapses. The elapse of the stop display fixed time Twait1 can be measured by, for example, starting a timer (not shown).

  In the illustrated example, the change of the normal symbol and the decorative symbol for the normal symbol is resumed by releasing the stop state at time t23 when the fixed stop display time Twait1 elapses. After that, since the regular drawing lottery was won at time 24, the reach mode is displayed with the hit variation, and at time t25, the variation of the special symbol and the special symbol decorative symbol is started. Since the result of the first winning / losing lottery held when the start port 62 is opened was a win, the change time T5 of the second change corresponding to the win is set as the stop display fixed time Twait2. As a result, the stop state of the normal symbol is maintained until the stop display fixed time Twait2 elapses in addition to the waiting time Twait02 until the special symbol variation started when the start port 62 is opened.

  In this way, by accurately calculating the total variation time of the special symbol by so-called prefetching, it becomes possible to easily control the variation stop of the special symbol and the special symbol decoration symbol. Regardless of whether or not it is the start time of the change of the special symbol, since the information of the change time is acquired in advance, there is no need to perform a special design such as fixing the change time of the special symbol, and the degree of freedom of design Benefits such as increased.

  In addition, in this modification, although the example which calculates the sum total of the fluctuation time of the special symbol after the 2nd change was shown at the time of the ordinary electric accessory 65 closing, the method of not calculating the sum of the fluctuation time in this way is shown. It can also be taken. For example, the number of reserved balls at the time when the ordinary electric accessory 65 is closed is read, and when the special symbol variation related to the last held ball is stopped, the main display control unit 118 sends a stop signal to the symbol mode determining unit 131. It is also possible that the symbol pattern determining means 131 cancels the normal symbol fluctuation stop state.

[Modification 3]
FIG. 21 is a schematic diagram illustrating a board configuration of a game board according to another modification. FIGS. 9A and 9B show changes in the display mode of the special-purpose decorative symbols.
In the present modification, a first display device 265 composed of a liquid crystal display is disposed at the center of the game area 52, and a pair of second display devices 264 composed of 7-segment LEDs are disposed at the upper left and right positions thereof. The left and right second display devices 264 each display a general-purpose decorative design 291, and the central first display device 265 displays a special-purpose decorative design 290.

  During the fluctuation of the general-purpose decorative design 291, as shown in FIG. 5A, the front surface of the first display device 265 is covered with the shutter 266, and the special-purpose decorative design 290 is not displayed. It becomes. On the other hand, when the decorative pattern 291 for normal use is stopped by the hit design of the reach mode, the shutter 266 is opened by the accessory driving device 270, and the liquid crystal display screen 260 appears as shown in FIG. Then, the special design decorative pattern 290 is displayed. As described above, the special-purpose decorative pattern 290 and the general-purpose decorative pattern 291 may be displayed on different display devices or in different modes.

[Modification 4]
In the above embodiment, as described with reference to FIG. 7, the contents of the general-purpose figure determination table corresponding to the gaming state are made substantially the same regardless of the normal symbol. In the modified example, a bias may be provided such that a correspondence relationship between the symbol lottery value and the general-purpose decorative symbol is assigned so that the frequency indicating the current gaming state becomes more prominent depending on the normal symbol. For example, for the general-purpose figure determination table “1-A”, “3” or “7” is a high probability as a general-purpose decorative symbol when the current gaming state is a probabilistic state and a high probability setting state. However, the probability may be further increased as the number of selected normal symbols increases. That is, the symbol lottery value range may be assigned so that the probability gradually increases in the order of “1-A”, “3-A”, “5-A”, and “7-A”. In this way, when “3” or “7” is displayed as the decorative symbol for the general map, it is possible to make the player strongly recognize that the current gaming state is the highest state. Expectation by design can be further enhanced.

[Modification 5]
In the said Example, the example in which the game state after a special game was set by the symbol determination table shown in FIG. 9 was shown. In a modified example, the gaming state set in such a manner may be switched depending on the number of fluctuations after the special game. For example, even if the special symbol “1” is selected and the transition to the highest state “A” is made, if the number of fluctuations of at least one of the normal symbol and the special symbol exceeds a predetermined number (for example, 50 times) after the special game, The state may be switched to the lower state “B” by one step. Alternatively, the game state (that is, the combination of the probability variation state and the probability setting state) is switched by winning the general drawing lottery after a special game, or the game state is switched by entering a game ball into a specific entrance. May be.

[Modification 6]
In the above embodiment, based on the special symbol determined when the winning lottery wins, the combination of the gaming state after the special game (that is, whether or not to become a probable change state and whether or not to become a high probability setting state) ) Was given. In the modified example, in addition to the determination of the special symbol, the gaming state after the special game (that is, the combination of the presence / absence of the probability change and the level of the probability setting state) may be determined according to the gaming state so far. For example, when the gaming process of a predetermined period is monitored, and it is determined that the frequency at which the special game is not executed even if the number of changes of at least one of the special symbol and the normal symbol exceeds a predetermined number (for example, 500 times) is higher than the reference value Alternatively, the gaming state may be switched to a relatively high state, for example, when the special game executed after the determination is finished, the probability changing state and the high probability setting state. On the other hand, the game process for a predetermined period is monitored, and the frequency at which the special game is executed even though the number of changes of at least one of the special symbol and the normal symbol is less than a predetermined number (for example, 100 times) is a criterion value. When it is determined that the game state is higher, the gaming state may be switched to a relatively low state, such as a normal state and a low probability setting state triggered by the end of the special game executed after the determination. By doing in this way, the excessive bias of the jackpot probability between gaming machines can be suppressed.

[Modification 7]
In the above-described embodiment, a method is adopted in which the change time of the special symbol is fixed and the stop display fixed time (Twait) of the decorative symbol for the general map is set assuming the maximum number of reserved balls. In the modified example, the stop display fixing of the decorative symbol for the general symbol is started at the start of the variation of the special symbol, and then the variation time is extended as an additional fixed stop display time every time the variation of the special symbol is started. Thus, the stop display state of the period corresponding to the number of reserved balls of the winning / losing lottery value may be held. By doing so, it is possible to properly maintain the stop display state of the decorative symbols for ordinary drawings without performing so-called prefetching.
