Description

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

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

  In the pachinko gaming machine, there may be provided a specific game that keeps the player in an advantageous state until the symbol variation count reaches a predetermined upper limit count. For example, the fluctuation time shortening game (hereinafter, also referred to as “short time” as appropriate) that executes the lottery determination at short intervals by shortening the symbol variation time than usual, and the probability of winning in the lottery lottery higher than usual This is a probability fluctuation state (hereinafter also referred to as “probability change” as appropriate).

The upper limit number of times of a specific game may be a fixed number that is determined in advance as a specification of the gaming machine, or may be a specification in which the number of times is determined every time a transition to a specific game is made. In addition, if the upper limit number is a fixed specification, the number may not necessarily be displayed. However, in the case of a specification that is determined each time, there is a specification that explicitly displays this, but do not display it to the player. In some cases, the specification is concealed. In any case, the length of the upper limit number of times in a specific game is an element that influences the magnitude of the player's profit, and the player's expectation increases with the length of the number of times. Therefore, a technique for changing the upper limit number of time reductions during a specific game has been proposed (see, for example, Patent Document 1).
JP 2002-126284 A

  Among games in pachinko gaming machines, there is a game in which a maximum period is set and a profit is provided to the player from the start of the game to the maximum period. For example, there are special effects such as time reduction, probability change, and other limited periods. Normally, when a big hit occurs, this game is terminated midway even if the maximum period has not elapsed. Therefore, the player may not be able to enjoy at least a part of the benefits that should be originally enjoyed from this game. In particular, if a big hit occurs with most of the scheduled game period remaining, the player will not be able to enjoy the profits that should have been originally enjoyed from this game, and the player will have a sense of loss. was there.

  The present invention has been made in view of these problems, and the main purpose of the present invention is to prevent the player from having a sense of losing the game for which the maximum period is set in the ball game machine. Is to decide.

  In order to solve the above-described problem, a bullet ball game machine according to an aspect of the present invention includes a game board in which a game area is formed, a start port provided at a predetermined position in the game area and into which a game ball can enter, Special game execution means for executing a special game that is more advantageous to the player than a normal game when the game ball enters the starting port and a predetermined transition condition is satisfied, and a maximum of the game period Special game execution means for executing a special game, which is a game for which a period has been set, and special game period determination means for determining the maximum period each time a special game is executed. After determining the maximum period of the special game, the special game period determining means satisfies the predetermined end condition before the maximum period of the special game elapses, and the special game ends with at least a part of the maximum period remaining. Then, the maximum period of the special game newly determined after the game executed in accordance with the satisfaction of the end condition is determined to be at least a period longer than the remaining period of the special game completed in accordance with the satisfaction of the end condition.

  The ball ball game machine in this aspect may be a conventional first type pachinko game machine, a second type pachinko game machine, or a game machine in which a plurality of them are mixed.

  The special game in this aspect may provide a profit to the player from the start of the game to the maximum period. For example, it may be a specific game such as a probability change that increases the probability of transition to a special game, or a short time that suppresses a decrease in a player's possession. Also, for example, it may be a game with an effect to entertain a player with a maximum period set, and specifically, the condition that the symbol variation display mode should satisfy within a specific period is presented as a jackpot condition It may be a game with a directed effect. The longer the maximum period of special games is, the more profitable the player is. Therefore, the maximum period of post-game special games (hereinafter simply referred to as “subsequent special games”) that have been executed in accordance with the satisfaction of the end condition ends. When the remaining period of a special game (hereinafter simply referred to as “previous special game”) that has ended due to the satisfaction of the conditions is less than the remaining period, it is easy for the player to feel lost.

  In addition, satisfaction of a predetermined end condition means that an opportunity to end a special game has occurred, and for example, a transition to a special game or execution of a specific effect may be performed. “The special game has ended with at least a part of the maximum period remaining” means that the special game being executed has ended and the special game scheduled to be executed is not executed. Including that it ended.

  According to this aspect, the maximum period of the later special game is set to be longer than the remaining period of the previous special game. Therefore, the player can enjoy a profit more than the profit that should have been obtained from the previous special game when the end condition is not satisfied from the subsequent special game. Thereby, the player can be satisfied without giving the player a sense of loss.

  Triggering lottery means for executing a lottery determination for determining whether or not to shift to a special game triggered by entering the starting opening, a symbol display device for variably displaying a symbol for showing the result of the lottery, May be further provided. The special game execution means executes a game having a maximum duration in the form of the upper limit number of times of the variable display of symbols as a special game, and the special game period determination means determines the special game after determining the upper limit number of special games. When the predetermined end condition is satisfied before the upper limit number of times is reached, and the special game is ended with at least some of the upper limit number of remaining display times remaining, the remaining variable display number is specified as the remaining number of times, For the special game after the game executed in accordance with the satisfaction of the end condition, the upper limit number of times may be determined to be at least the number of remaining times.

  According to this aspect, for a special game in which the upper limit number of symbol fluctuations is set, the upper limit number of later special games is set to be equal to or greater than the remaining number of previous special games. Since the number of symbol fluctuations is easily linked to the player's profits in pachinko machines, the upper limit is intuitive for the player, for example, compared to time, etc. The impact on is great. Therefore, this aspect is suitable for satisfying the player without giving the player a sense of damage.

  The special game execution means executes, as a special game, a game that is more advantageous to the player than the normal state in a normal game after the special game is finished until the maximum number of times the symbol display is changed. After the determination of the upper limit number of special games, the determining means satisfies the end condition by making a transition to the special game before reaching the upper limit number of the special game. When the special game ends with the remaining number of times remaining, the remaining variable display number may be specified as the remaining number of times, and the upper limit number of special games after the end of the special game may be determined to be at least the number of remaining times or more.

  According to this aspect, the upper limit number of symbol fluctuations in a special game after a special game, for example, time reduction or probability change, is set to be equal to or greater than the remaining number of times of the previous special game. These special games have a great influence on the player's possession, and the length of the upper limit number has a great influence on the player's profit and loss account. Therefore, this aspect is suitable for satisfying the player without giving the player a sense of damage.

  The game ball is placed at a predetermined position in the game area, and the game ball can be received at the start port to change to a state that is advantageous to the player. And open lottery means for executing an open lottery for determining whether or not to perform. The starting port is expanded for a predetermined time according to the result of the open lottery, and the special game executing means is the open lottery in the open lottery means in the normal game after the end of the special game until the maximum number of symbol display is reached. Among the games in which the game is changed to a state advantageous to the player, the game in which the opening time of the start port is extended, and the game in which the variation time of the symbol is shortened, at least one game may be executed as the special game Good.

  According to this aspect, time saving is executed as a special game. In terms of time savings, typically, a game with a shortened open lottery time, a game with a higher probability of winning the open lottery, a game with a longer opening time of the opening, and a game with a shorter symbol variation time. Among them, at least one game is executed. Since this time limit suppresses the decrease in the player's possession, the length of the upper limit number of times has a great influence on the player's profit and loss account. Therefore, this aspect is suitable for satisfying the player without giving the player a sense of damage.

  The special game period determining means, when the remaining period of the special game that has been completed due to the satisfaction of the termination condition is not less than a predetermined period, the maximum period of the special game after the game that has been performed according to the satisfaction of the termination condition The period may be determined. This predetermined period may be set once, or may be set to the minimum period among the periods that can be set as the maximum period of the subsequent special game. In any case, the maximum period of the subsequent special game is set at least longer than the remaining period of the previous special game. Thereby, the player can be satisfied without giving the player a sense of loss.

  The special game period determining means newly sets the maximum period for the special game after the game executed in accordance with the satisfaction of the end condition when the remaining period of the special game ended in accordance with the completion of the end condition is less than the predetermined period. You may decide. This predetermined period may be set once, or may be set to the minimum period among the periods that can be set as the maximum period of the subsequent special game. In any case, the maximum period of the subsequent special game is set at least longer than the remaining period of the previous special game. Thereby, the player can be satisfied without giving the player a sense of loss.

  The special game period determining means newly specifies the maximum period of the special game after the game executed in accordance with the satisfaction of the termination condition, and the maximum period is less than the remaining period of the special game terminated in accordance with the satisfaction of the termination condition. The maximum period may be determined as the remaining period. In this case, the maximum period of the subsequent special game is set at least longer than the remaining period of the previous special game. Thereby, the player can be satisfied without giving the player a sense of loss.

  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.

  In the following embodiment, a short time is shown as a specific example of a special game in which the maximum period is set so as not to give the player a sense of loss. Further, specific game execution means is shown as a specific example of the special game execution means, and specific game period determination means is shown as a specific example of the special game period determination means.

  According to the bullet ball gaming machine of the present invention, it is easy to determine the maximum period of the game for which the maximum period is set so that the player does not have a sense of loss.

The upper ball tray 15 has a mechanism for storing game balls, sending out the game balls to the launch rail, and extracting the game balls to the lower ball tray 16. The lower ball tray 16 has a mechanism for storing and extracting game balls. A speaker 18 is provided between the upper ball tray 15 and the lower ball tray 16, and a sound effect corresponding to the gaming state is output.

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

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

  The special symbol display device 61 provided on the left side of the game area 52 and the effect display device 60 provided in the approximate center of the game area 52 have a variation of the special symbol 192 on each screen and a decoration linked to the special symbol 192. The variation of the effect image including the symbol 190 is displayed (hereinafter, such display is referred to as “symbol variation” or “variation display”). Here, the special symbol 192 is a symbol corresponding to the result of the lottery performed when the game ball is dropped into the start port 62, and the symbol mode when the change display is stopped is determined to be the winning symbol. When the symbol is a symbol, the timing at which the stop symbol is displayed is the jackpot occurrence timing. The special symbol display device 61 is display means composed of, for example, 7 segment LEDs. The effect display device 60 is a liquid crystal display that variably displays the decorative symbol 190 in a manner interlocked with the variation display of the special symbol 192. The decorative symbol 190 is a symbol for visually rendering the lottery result display indicated by the special symbol 192. The effect display device 60 displays, as the decorative symbol 190, for example, a plurality of rows of moving images of symbol variation simulating a slot machine game in the central area of the screen. The effect display device 60 is constituted by a liquid crystal display in this embodiment, but may be constituted by a mechanical rotating device such as a drum or other display means such as an LED. Since the special symbol 192 does not necessarily have a role of production, in this embodiment, the special symbol 192 is displayed in an inconspicuous size on the special symbol display device 61 at the lower left of the production display device 60. In the case of adopting a technique in which a decorative role is not displayed and a decorative symbol is not displayed, the special symbol may be displayed on a liquid crystal display such as the effect display device 60. The operation port 68 is provided at the left side position of the game board 50. The operation port 68 includes a passage detection device 69. The passage detection device 69 is a sensor that detects the passage of the game ball to the operation port 68, and generates passage information indicating the passage at the time of passage. The passage of the game ball to the operation port 68 triggers an open lottery for determining whether or not to expand the expansion mechanism of the start port 62. When the game ball passes through the operation port 68, a normal symbol, which is a symbol indicating the result of the open lottery, is variably displayed on the normal symbol display device 59. The normal symbol display device 59 is provided on the lower right side of the effect display device 60. When the normal symbol variation display is stopped after a predetermined time has elapsed, the start port 62 is normally expanded for a predetermined time with a probability of about 50% to 80%.

  A center ornament 64 is provided around the effect display device 60. The center decoration 64 has functions such as a flow path of the game ball, protection of the special symbol display device 61 and the effect display device 60, and decoration. A lottery hold lamp 20 is provided below the effect display device 60, and an operation hold lamp 22 is provided below the normal symbol display device 59 at the lower right of the game area 52, which is a symmetrical position. . The lottery hold lamp 20 is composed of four lamps, and displays the number of lottery holds depending on the number of lights. The number of lottery holds is the number of lottery results won to the start port 62 during symbol variation or special game, and indicates the number of winning balls for which symbol variation has not yet been executed. The operation hold lamp 22 is also composed of four lamps, and displays the number of hold of normal symbol fluctuations depending on the number of lights. The number of normal symbol fluctuations held is the number of game balls that have passed through the operation port 68 during the fluctuation of the normal symbol, and indicates the number of normal symbol lotteries for which the fluctuation of the normal symbol has not yet been executed. Furthermore, game effect lamps 90 are respectively provided above and below the effect display device 60. The operation button 82 is a button that the player operates 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 turns the launch handle 17 by hand, the game balls stored in the upper ball tray 15 are guided one by one to the inner rail 56 and the outer rail 54 with a strength corresponding to the turning angle, thereby playing the game area. To 52. When the player fixes the rotation position of the firing handle 17 by hand, the game ball is repeatedly fired at regular time intervals. The game ball launched to the upper part of the game area 52 falls in a direction according to the way of hitting while hitting a plurality of game nails and windmills. When a game ball is dropped into each of the general winning port 72, the start port 62, and the big winning port 66, the winning ball corresponding to the type of the winning port is paid out to the upper ball plate 15 or the lower ball plate 16. A game ball dropped into each winning hole such as the general winning hole 72 is processed as a safe ball, and a game ball dropped into the out hole 58 is processed as an out ball. Each winning opening includes a gate type through which a game ball passes. In this application, “incoming”, “entering”, and “winning” include “passing”.

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

  After the end of the special game, a probability variation game that is one of the specific games that is more advantageous to the player than the normal state, that is, a probability change is started. In a probability variation game, a lottery with a higher probability of winning than a normal probability state is performed, and the possibility that a new special game will be generated increases. The probability change in the present embodiment is started when the special game is ended, and is ended when the game is shifted to a new special game or a predetermined number of symbol fluctuations is reached.

  After the end of the special game, a variable time shortening game that is one of the specific games, that is, a time reduction is also started. That is, after the special game in the present embodiment is finished, the probability change and the time reduction are started simultaneously, and after the predetermined symbol variation number of times and the probability change is completed, only the time reduction is continued. As a modification, the time reduction may be started after the end of probability change. In time saving, the variation time of the special symbol and the decorative symbol is shortened from the normal time. The variation time of the special symbol and the decorative symbol is returned to the original variation time after the variation display is performed until the special game is shifted to the special game or the upper limit number determined after the special game is reached. When the fluctuation time is shortened, the number of symbol fluctuations in a certain period of time increases, so that the hold lottery value hold by the hold control means 116 is digested earlier than usual. In addition, during the time reduction, the variation time of the normal symbol is shortened, the probability of the normal symbol lottery is changed to a high probability state, and the time for the expansion mechanism of the start port 62 to be expanded is extended. As a result, since the opening mechanism of the start port 62 is frequently expanded during the time shortening and an increase in the number of game balls can be expected, a lot of winning / failing lotteries are performed in a short period of time while the decrease in the number of winning balls is suppressed. Can be executed. Therefore, the player can obtain the advantage that the lottery corresponding to the number of times corresponding to the upper limit number can be obtained substantially without using the possession ball from the short time. Therefore, whether or not the upper limit number of time reductions is large is directly related to the profit of the player and affects the player's profit and loss account.

  Further, in this embodiment, when a transition is made to a new special game during the probability change and time reduction, the probability change and time reduction being executed are terminated and the special game is executed. Thereafter, after the special game is finished, a new probability change and time reduction will be started.

  The symbol determination means 114 acquires a symbol determination lottery value for determining a special symbol, and determines the stop symbol of the special symbol according to the determination result of the success / failure lottery means 112 and the symbol determination lottery value. The symbol determination unit 114 selects one of a plurality of variation patterns in accordance with the determination result of the success / failure lottery unit 112. The symbol determination unit 114 sends data indicating the determined stop symbol and variation pattern to the main display control unit 118 and the effect determination unit 132.

  The symbol determination means 114 stores a plurality of types of variation patterns in which variation modes from the variation start to the stop when the special symbol is variably displayed are defined. Multiple types of variation patterns have various variation times. That is, for each variation pattern, a variation display time is defined for each pattern as an end condition of the symbol variation, and the variation of the special symbol is stopped when the variation display time elapses. The symbol determination means 114 determines the variation pattern with reference to a table for selecting a variation pattern whose variation time is generally shorter than that in the normal state during the time reduction.

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

  The hold control means 116 holds the winning / losing lottery value acquired by the winning / failing lottery means 112 as a holding ball. The success / failure lottery value is accumulated until the number of holds reaches a predetermined upper limit. The upper limit of the number of holds is 4.

  The main display control means 118 causes the special symbol display device 61 to display the lottery result by the success / failure lottery means 112 as a special symbol variation display according to the variation pattern determined by the symbol determination unit 114. The main display control means 118 transmits the change start command and the change stop command to the effect display control means 134 at the timing of starting and stopping the change display of the special symbol, so that the main display control means 118 and the effect display are displayed. The fluctuation display by the control means 134 is synchronized and interlocked. The main display control means 118 displays the normal symbol variation on the normal symbol display device 59.

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

  The specific game control means 121 is a functional block that controls the operation of a specific game. The specific game in this embodiment is probable and short. The specific game control means 121 determines the upper limit number of time savings after a special game to be equal to or more than the number of symbol fluctuations (hereinafter also referred to as “residual fluctuation number” as appropriate) remaining in the time reduction executed at the time of transition to the special game. To do. As described above, the ease of entering the starting port 62 is improved due to the short time, and the fluctuation time of the special symbol and the decorative symbol is shortened from the normal time. In some cases, the time to hit can be shortened. Therefore, by determining the upper limit number of time savings after a special game as described above, the aim is to satisfy the player without giving the player a sense of loss.

  The specific game control unit 121 includes a specific game period determination unit 123 and a specific game execution unit 122. The specific game period determining means 123 determines the upper limit number of time reductions based on the result of the success / failure lottery received from the success / failure lottery means 112 and the state of the special game received from the special game control means 120.

  Specifically, the specific game period determining unit 123 detects the shift to the special game based on the result of the success / failure lottery received from the success / failure lottery unit 112. At this time, the specific game period determination means 123 temporarily stores the short-time remaining fluctuation count that is ended by the transition to the special game.

  The specific game period determining unit 123 detects the end of the special game based on the special game state received from the special game control unit 120. At this time, the specific game period determining unit 123 first specifies a basic upper limit number of times (hereinafter, also referred to as “basic variation number” as appropriate) according to the winning / losing lottery value received from the winning / failing lottery unit 112. For example, the number of basic changes may be specified with reference to a table that stores the corresponding lottery values and the number of basic changes. As a modification, the specific game period determining means 123 may specify the number of basic fluctuations according to the pattern of winning stop symbols, or may specify the number of basic fluctuations by executing a unique lottery.

  Subsequently, the specific game period determining unit 123 compares the basic variation number with the remaining variation number when determining the upper limit number of time reductions. The specific game period determining means 123 determines the upper limit number of time reductions as the basic variation number when the remaining variation number is not stored or when the basic variation number is equal to or greater than the remaining variation number. Further, when the basic fluctuation number is less than the remaining fluctuation number, the upper limit number of time reductions is determined as the remaining fluctuation number. The specific game period determining unit 123 notifies the specific game effecting unit 138 of the finally determined upper limit number of times, and if the upper limit number and the basic variation number are different, the basic variation number is also specified by the specific game. The effect means 138 is notified. As a modified example, when the specific game effect means 138 does not require the number of basic fluctuations, for example, when the special game effect means 138 does not execute a special effect related to the change of the upper limit number of times, the specific game period determination means 123 is Only the upper limit number of times may be notified to the specific game effect means 138 at all times.

  The specific game executing means 122 executes control for shifting the game state from the normal state to the specific game state and control for returning from the specific game state to the normal state based on the state of the special game received from the special game control means 120.

  Specifically, the specific game execution unit 122 detects the end of the special game based on the state of the special game received from the special game control unit 120. At this time, the specific game execution means 122 shifts the game state after the special game to the probabilistic and short-time state regardless of the winning / losing lottery value. The specific game execution means 122 continues the probability variation state until the number of times the special symbol fluctuates in the probability variation state reaches a predetermined number, for example, four times. During the probability variation state, the probability of the hit determination by the success / failure lottery means 112 is maintained at a high value.

  In addition, the specific game execution unit 122 continues the short time state until the number of changes in the special symbol in the short time state reaches the upper limit number determined by the specific game period determination unit 123. In this embodiment, since the upper limit number of time reductions is set larger than the upper limit number of probability changes, the specific game execution means 122 starts the probability change state and the time reduction state at the same time, and then ends the probability change state first. After that, only the short-time state is continued. As a modified example, the specific game executing means 122 may start only the probability change state first, and after shifting the probability change state, may shift the game state to the time-short state. In addition, the specific game execution means 122 notifies the specific game effect means 138 of the remaining number of times of the variation of the special symbol in the probability change and the time reduction.

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

  The pattern storage unit 130 holds a plurality of variation pattern data in which a variation process from variation start to stop in variation display is defined as a variation pattern of the effect image including the decorative design. In the fluctuation pattern, a pattern for displaying a normal out symbol, a pattern for displaying a symbol out of reach after reaching a big win if one more symbols are aligned, and a jackpot symbol through a reach state are displayed. When the pattern is included. In particular, the pattern that passes through the reach state includes patterns having various fluctuation times. A variation pattern in which the variation time for displaying the time is relatively short is also included. A so-called pseudo continuous variation pattern is also included. The quasi-continuous variation pattern is a pattern that displays symbol variation that is continuously made a plurality of times in a pseudo manner with respect to one winning / failing lottery. Each variation pattern has a variation time for each pattern as an end condition of the symbol variation, and the symbol variation is stopped when the variation time elapses. The effect determining means 132 selects the variation pattern of the effect image having the same variation time as that of the special symbol according to the variation pattern of the special symbol.

  The effect determining means 132 determines the combination of the stop symbols of the decorative symbols and their arrangement and variation pattern according to the result of the lottery by the success / failure lottery means 112, according to the stop symbol of the special symbol and the variation pattern of the special symbol. The effect determining unit 132 holds a symbol range table to be referred to in order to determine a stop symbol of a decorative symbol and a pattern table to be referred to in order to determine a variation pattern.

  The stop symbol of the decorative symbol is formed as a combination of three symbols. For example, when the determination result by the success / failure lottery means 112 indicates a shift to a special game, three symbols such as “777” and “111” are arranged. A combination is selected. In this case, it is preferable that the same numbers as the special symbols are selected as the numbers arranged as the decorative symbols. For example, when the special symbol is “3”, the decorative symbol is “333”. In the case where the determination result by the success / failure lottery means 112 indicates that the game does not shift to the special game, a combination that does not have three symbols such as “312” and “946” is selected. However, if the determination result is that the game does not shift to a special game, and a variation pattern of a special symbol indicating a loss with reach is selected, only one such as “191” or “727” is selected. Select a combination that does not have the same pattern. The effect determining unit 132 sends information about the stop symbol of the decorative symbol and the variation pattern of the effect image to the effect display control unit 134.

  The effect display control means 134 displays the effect image on the effect display device 60 in accordance with the selected variation pattern data as a result of the success / failure lottery by the success / failure lottery means 112. 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.

  Based on the information received from the specific game control means 121, the specific game effect means 138 executes effect processing related to the specific game, for example, effect display on the effect display device 60 and effect sound output from the speaker 18. . In the present embodiment, the data notified from the specific game period determining means 123, that is, the upper limit number of time reductions is displayed on the effect display device 60. In addition, when the basic fluctuation count of the short time is also notified, the basic variation count and the upper limit count are displayed on the effect display device 60 in an effect. Further, the data notified from the specific game execution means 122, that is, the probability change and the remaining number of time savings are displayed on the effect display device 60. As a modified example, the specific game effect means 138 does not execute a special effect and displays only the upper limit of the time limit on the effect display device 60 even if it is notified of the basic fluctuation count of the short time. Also good.

  FIG. 4 schematically shows the screen contents in this embodiment. FIG. 4A shows the screen content at the start of the special game. On the screen 200, three decorative symbols 190 are scrolled in the vertical direction at left, center, and right positions as display contents during a normal game, and symbol variation is executed. FIG. 4A shows a state in which the decorative symbols 190 are aligned with “7”. FIG. 4B shows a screen 200 on which the upper limit number of times is displayed after the special game ends. In the figure, the time limit notification 202 displayed by the specific game effect means 138 shows the upper limit number of times “100 times”. FIG. 4 (c) shows a screen 200 showing probability change and time reduction. In the figure, in the probability variation remaining count 204 displayed by the specific game effect production means 138, the remaining probability variation state count “3 times” is displayed. In addition, in the short time remaining number 206 displayed by the specific game effect means 138, the remaining number of short time “99 times” is displayed. That is, it is displayed that the probability change and the time reduction are each digested once.

  FIG. 5 also schematically shows the screen contents in the present embodiment. 5A, 5B, 5C, and 5D show a case where the upper limit number of time reductions is determined to be the number of remaining short time fluctuations that ended first. FIG. 5A shows a screen 200 indicating that the probability change is in progress shown in FIG. The figure shows a state in which the decorative symbols 190 are aligned with “1” during the probability change and the special game is started. In the case of the conventional pachinko gaming machine, the short-time remaining fluctuation count “97 times” is reset at this point, but in the pachinko gaming machine 10 of this embodiment, the specific gaming period determining means 123 holds this remaining fluctuation count. . In the example of FIG. 5, the basic variation number of the short time specified after the special game is ended by the specific game period determining means 123 is “20 times”, and the upper limit number of times of the short time is determined to be “97 times”. The specific game number of times and the upper limit number of times are notified to the specific game effect means 138.

  FIG. 5B shows a screen 200 on which the basic variation number “20 times” is first displayed as the upper limit number of time savings after the end of the special game. FIG. 5C shows a screen 200 displayed when the specific game effect means 138 is notified of both the basic variation number and the upper limit number from the specific game period determination means 123. That is, the player is informed that the upper limit number of times is changed so that there is merit for the player. FIG. 5D shows a screen 200 on which “97 times” that is the finally determined upper limit number is displayed as the upper limit number of times. The player looks at FIG. 5 (b) and feels that he has once lost, but sees FIG. 5 (c) and FIG. It feels like you didn't do it and makes you feel better. As described above, when a special effect is not executed in the specific game effect means 138, FIG. 5B and FIG. 5C are not displayed, and FIG. 5D is displayed after FIG. ) May be displayed, and only the upper limit number of time reductions may be indicated.

The operation of the above configuration will be described below.
FIG. 6 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, prize ball payout corresponding to various winnings is processed.

  FIG. 7 is a flowchart showing in detail the normal game control process of S14 in FIG. In the normal game control process, if the winning / losing lottery value is on hold (Y in S30) and the symbol variation is not being displayed (N in S32), the winning / losing lottery means 112 executes the determining process. (S34). In this success / failure determination process, a success / failure lottery is executed, and a symbol and a variation pattern are determined. Details of the success / failure determination process will be described with reference to the flowchart of FIG. In accordance with the determination result of S34, the main display control means 118 starts changing display, transmits a change start command to the effect display control means 134, and the effect display control means 134 that receives the command displays the effect image according to the change pattern data. The fluctuation display is started (S36). At this time, when a reach variation pattern or a specific variation pattern is selected in S34 as an adjustment opportunity effect, symbol variation by the variation pattern is started. If the winning or failing lottery value is not held in S30 (N in S30), the processing from S32 to S36 is skipped, and if the symbol variation is being displayed in S32 (Y in S32), S34 and S36 Is skipped. Subsequently, if the symbol variation display has already started (Y in S38), the symbol variation display process is executed (S40). If the symbol variation display has not started (N in S38), S40 is skipped. .

  FIG. 8 is a flowchart showing in detail the success / failure determination process of S34 in FIG. First, the success / failure lottery means 112 reads the success / failure lottery value (S42), and determines the success / failure based on the success / failure lottery value (S44). When it is determined that the winning / failing lottery means 112 is a win (Y of S46) and the number of symbol fluctuations of the short time during execution or the time when the execution is scheduled remains (Y in S48), the specific game period determining means 123 remains. The number of changes is stored (S50). If it is not a hit (N of S46), S48 and S50 are skipped. Further, if the short time symbol variation count does not remain (N in S48), S50 is skipped. The symbol determining means 114 determines a stop symbol of the special symbol based on the determination result (S52), and selects a variation pattern of the special symbol (S54). The effect determination means 132 determines the stop symbol combination of the decorative symbols based on the determination result and the special symbol (S56), and selects the variation pattern of the decorative symbol according to the variation pattern of the special symbol (S58).

  FIG. 9 is a flowchart showing in detail the special game control process of S16 in FIG. First, if the special winning opening 66 has not been opened (N in S72), the production display control means 134 starts the special game production process (S73), and the opening / closing control means 124 opens the special winning prize port 66 (S74). ). If the special winning opening 66 has been opened, S73 and S74 are skipped (Y in S72). 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 (S85). After the special game ends, the specific game period determining means 123 determines the upper limit number of time reductions (S86). The specific game effect means 138 displays the upper limit number of time reductions on the effect display device 60 and notifies the player (S87). The specific game executing means 122 starts a specific game including the probability change in which the predetermined number of symbol fluctuations is set as the upper limit number and the short time in which the upper limit number determined in the specific game period determining means 123 is set (S88). . If the number of rounds in the unit game has not reached 15 (N in S82), 1 is added to the number of rounds, and the flow in S16 is terminated (S90).

  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. Hereinafter, modifications will be described.

  In the present embodiment, the larger number of times of the basic variation number and the remaining variation number newly specified after the end of the special game is determined as the upper limit number of times. The specific game period determining means 123 of the modified example may determine the remaining variation number as the upper limit number of times without specifying the basic variation number if the remaining variation number is equal to or greater than a predetermined threshold. For example, by setting this threshold value to once, if there is a remaining fluctuation count, the remaining fluctuation count is determined as the upper limit number of times. Also, for example, by setting this threshold to the minimum period (hereinafter also referred to as “minimum basic fluctuation frequency” as appropriate) among the periods that can be specified as the basic fluctuation frequency, More than the number of times and more than the number of remaining fluctuations are set.

  If the remaining variation count is less than a predetermined threshold, the specific game period determination unit 123 according to another modification may newly specify the basic variation count and determine the basic variation count as the upper limit count for the time reduction. . For example, by setting this threshold value to once, if there is no remaining fluctuation number, the basic fluctuation number is newly specified and determined as the upper limit number of times. Further, for example, by setting this threshold value to the minimum number of basic fluctuations, the upper limit number of time reductions is set to a number that is equal to or greater than the minimum number of basic fluctuations and equal to or greater than the remaining fluctuation number.

  In the present embodiment, the short time has been described as an example of the special game in which the maximum period is set. In the modified example, the present invention is realized by setting the upper limit number of times in the probability change which is one of the specific games, and determining the upper limit number of the probability change more than the number of remaining fluctuations of the probability change executed at the time of transition to the special game. Also good. In other words, the probability change in which the upper limit number is set may be a special game. In the probability variation state, the probability of winning or failing the winning lottery is changed to a high probability state, so whether the maximum number of probability variation is large is directly linked to the player's profit, and the upper limit number is set to be more than the remaining variation number. By doing so, the player can be satisfied. Of course, the present invention may be realized by determining the upper limit number of both the probability change and the time reduction to be equal to or more than the respective remaining fluctuation number.

  As another modification, the special game with the maximum period set may be a game with an effect for entertaining the player with the maximum period set. In this modification, the effect display control means 134 determines a specific period and an aspect condition that is a condition to be satisfied by the symbol variation display aspect within the period as a start condition of a game that provides a profit to the player. Condition determining means may be included. Further, the effect display control unit 134 causes the effect display device 60 to display a condition presentation effect (hereinafter also referred to as “mission” as appropriate) including display of the period and mode condition determined by the condition determining unit. Means may be included. In this mission, a specific period and mode condition may be presented to the player as a jackpot condition, and an effect may be executed instructing the player to realize a specific display mode.

  The condition determining means of this modification corresponds to the special game period determining means in the claims, and also corresponds to the specific game period determining means 123 in the embodiment. The condition presentation effect control means corresponds to the special game execution means in the claims, and also corresponds to the specific game execution means 122 in the embodiment.

  In this modification, each time a mission is started, the condition determining means determines the mission period, typically the number of symbol variations. When a mission ends when a predetermined end condition such as the occurrence of a special game is satisfied, the condition determining means stores the remaining period of the completed mission. When a new mission is started after the end of the game due to the satisfaction of the end condition, the condition determining means determines the maximum duration of the new mission to be equal to or longer than the remaining period of the mission that has ended due to the satisfaction of the end condition. To do.

  In this modification, when the aspect condition is satisfied within the specific period, the effect display control means 134 may provide the player with a special effect that is not normally provided, and the special game control means 120. The special game execution process may be started at. That is, a game that is beneficial to the player is provided. Therefore, the length of the upper limit period of the mission is directly related to the profit of the player, and the player can be satisfied by determining the upper limit period to be equal to or longer than the remaining period of the mission that has been completed first.

  Further, in this embodiment, the specific game period determining means 123 determines the upper limit number of time reductions without receiving any intervention from the player. As a modification, the upper limit number of time reductions is determined by the specific game period determining means 123 according to the number of basic changes and the number of remaining changes as in the embodiment. You may produce as if the upper limit number of times was determined. For example, a specific operation input via the operation button 82 may be instructed to the player, and the effect display device 60 may produce an effect such that the upper limit number of time reductions is determined advantageously for the player by the operation input. Further, for example, a mini game format in which the player selects an answer via the operation button 82 may be used. In any case, finally, the upper limit number of times that is determined in accordance with the basic variation number and the remaining variation number is presented to the player. In other words, the upper limit number of short times determined by the specific game period determining means 123 is presented so as not to give the player a sense of loss. In this way, by performing as if the player can intervene in determining the upper limit number of time reductions, it is possible to satisfy the player's sense of accomplishment and to further improve the game performance.

  In the present embodiment, a so-called first type pachinko gaming machine which has been conventionally used has been described as an example. In a modified example, it may be realized in a model in which a plurality of first type pachinko gaming machines are combined, or may be realized in a model in which first type pachinko gaming machines and second type pachinko gaming machines are combined. . In particular, in the latter case, in the short-time state after a jackpot is generated in the game corresponding to the first type pachinko game machine, the game performance that the probability of the jackpot occurring in the game corresponding to the second type pachinko game machine is substantially increased. Is assumed. In that case, in particular, the upper limit number of time reductions is directly linked to the player's profit, and the player can be satisfied by determining the upper limit number of time reductions to be equal to or greater than the remaining fluctuation number.
