Abstract

<P>PROBLEM TO BE SOLVED: To provide a performance control technique capable of further improving player's expectations and interest during probability variation. <P>SOLUTION: When the result of winning/losing drawing during the probability variation is a specified probability variable winning, a ready-to-win performance by normal symbols is intentionally performed. That is, after instigating player's sense of crisis by suggesting the possibility of probability variation end on a performance by the ready-to-win performance by the normal patterns, the performance of escaping from the probability variation end is performed by the performance of a special game. While a player tends to have the feeling of relatively losing generally when shifting to the special game of a little profit state, by making the special game take the charge of a gap on the performance such as a relief from the probability variation end, the player is made to recognize the effectiveness. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to a ball game machine such as a pachinko game machine, and more particularly to an effect control technique in a ball game machine.

  Conventionally, among the various ball game machines, a so-called first type pachinko game machine is used while changing a plurality of symbols in a display area such as a liquid crystal display provided substantially at the center of the game board. Display (hereinafter, such display is referred to as “symbol change” or “change display”). This gaming machine shifts to a special game called so-called jackpot where more prize balls can be obtained than a normal game when a combination of symbols when a plurality of rows of symbol variations are stopped becomes a specific mode. It is known as a thing (for example, refer patent document 1). The variation display of the symbols in the display area is not just a variation display of multiple symbols, but the time of variation display in a state where it is a big hit if one more symbols are aligned, as in the so-called reach variation screen. For example, it is designed to increase the player's expectation such as making it longer than usual.

Some gaming machines also shift the game state to a specific game advantageous to the player, which is called a so-called probability variation game (hereinafter also referred to as “probability change”) even after the special game is over. In other words, when a big hit occurs and the winning stop symbol at that time is a specific symbol (hereinafter referred to as “probability variation symbol”), the probability variation is started after the end of the subsequent special game. In this probability variation state, a lottery with a higher probability of winning than the normal probability state is performed and a new jackpot is generated relatively early, so that the player's expectation is further enhanced. In particular, when a new jackpot occurs during probability change and the winning stop symbol is a probability variation symbol, the probability variation state is continuously repeated across the special game, and the profit state of the player is further improved. For this reason, a player generally starts playing a game with the goal of continuing the probability change state in the normal game and continuing the special game as well as shifting to the special game.
JP 2003-230714 A

  In this way, since the continuation of the probability variation state generally requires that a jackpot at the probability variation symbol occurs during the probability variation, if the hit stop symbol during the probability variation is a normal symbol, the continuation of the probability variation state is It ends. Therefore, for example, when a reach state is reached with a normal symbol during probability change, the player has a sense of crisis toward the end of probability change as the performance with higher reliability to the jackpot is made. The inventors have come up with the idea that the expectation and interest of the player during probability change can be further enhanced by using the continuation condition of the probability change state in reverse.

  The present invention has been made in view of such problems, and a main object of the present invention is to provide an effect control technology that can further enhance the player's expectation and interest during probability change.

  In order to solve the above-described problems, a ball game machine according to an aspect of the present invention is provided with a game board on which a game area is formed, and a predetermined position in the game area. A winning lottery means for executing a winning lottery for determining whether or not to shift to a special game that is more advantageous to the player than a normal game, triggered by entering the starting prize port, The symbol display device in which the symbol for indicating the result of the winning / failing lottery is displayed in a variable manner, and the result of the winning / failing lottery indicating the transition to the special game, and the variation of the symbol in a predetermined stop mode indicating that the winning / raising lottery is a win The special game control means for executing the special game when the display is stopped, the variation of the symbol indicating the result of the success / failure lottery and the stop mode are determined, and the probability of the success / failure lottery after the special game is determined as the winning probability Higher than normal This is a probability variation with a decision to shift to a probability variation state, which is a state, and when displaying the confirmation per probability variation, a winning symbol combination based on a specific symbol is selected, but even if the result of the lottery is true, the probability variation Special game when symbol determination means for selecting a combination of winning symbols based on non-specific symbols when winning confirmation is not displayed, display control means for variably displaying symbols on the symbol display device, and when the result of the winning lottery is positive Specific game execution means for shifting the game state after the completion of the game to the probability variation state.

  The symbol determination means, when the result of the winning / failing lottery in the probability variation state is a specific probability change indicating that the transition to the special special game to be shifted to the probability variation state in a state where the profit state is less than the normal special game In addition, if one of the non-specific symbols is aligned, the symbol variation mode with the reach state that will be a winning symbol combination is selected, and the special game control means, if the result of the lottery is a certain probability variation In addition, the special special game is executed after the symbol change display with the reach state by the non-specific symbol is made.

Here, the “specific symbol” may be a so-called “probable variation symbol” in which the winning symbol combination indicates the certainty change transition. The “non-specific symbol” may be a so-called “ordinary symbol” indicating that the winning symbol combination has no probability change transition, and does not indicate the certainty change transition during the normal game, but during the special game It may be a so-called “chance symbol” that may develop (promote) the winning symbol combination to indicate the certainty change transition. The “chance symbol” may be temporarily changed to a winning symbol combination by “probability changing symbol” during a special game after being temporarily stopped by a winning symbol combination by “normal symbol” during a normal game. When a winning symbol combination based on “chance symbol” is selected, even if the result of the winning / failing lottery is a probability variation, the confirmation of the probability variation transition is not displayed during the normal game.
The state in which the profit state is less than that of a special special game may be a state in which, for example, in a gaming machine in which a special winning opening is opened when shifting to a special game, the special winning opening is opened only for a moment. However, it may be in a state where the special winning opening is not opened at all. As in the former case, the “specific probability change” for shifting to a special special game may include a hit with a so-called sudden probability change (hereinafter referred to as “surprise accuracy”) in which a probability change transition with substantially no play is made. When the symbol variation is stopped by the winning symbol combination by the specific symbol, the state shifts to the probability variation state after the special game. If the symbol variation is stopped by the winning symbol combination by the specific symbol during the probability change, the probability changing state will continue after the following special game, but if the symbol variation is stopped by the winning symbol combination by the non-specific symbol during the probability change, after the following special game There is a possibility of returning to the normal state.

  According to this aspect, when the result of the success / failure lottery during the probability change is per specific probability change, the reach effect is intentionally made with the non-specific symbol. In other words, after the player gives a sense of danger to the player by implying the possibility of the end of the probability change by the reach effect with the non-specific symbol, the effect is given to avoid the end of the probability change by executing the special special game. Thus, by creating a production gap that rescues the player from the crisis of probable end, the player's interest is further enhanced. From another point of view, when the player is shifted to a special special game with a small profit state in spite of the fact that the winning angle is obtained through a probabilistic state, the player tends to feel relatively lost. However, by making the special special game have a production gap such as relief from the end of the probability change described above, the player can recognize the effectiveness of the certain probability change. As a result, there is an advantage that the range of production is widened.

  The display control means, when the result of winning / failing lottery in the probability variation state is a specific probability variation, in order to make the symbol appear to have been temporarily stopped by the combination of the non-specific symbols. The symbol position of the symbol combination may be displayed in the semi-stop mode in which the symbol position is continuously finely moved in the front-rear direction, and then the symbol may be stopped and displayed in a winning symbol combination indicating that it is a specific probability variation. .

  According to this aspect, when the result of the winning / losing lottery during the probability change is a specific probability change, the winning symbol based on the non-specific symbol is pseudo-stopped and displayed in addition to the reach effect based on the non-specific symbol. For this reason, it is possible to make the player think that the probability change is finished, and to perform an effect as if the player has returned to the probability change state, and the impact on the effect is further enhanced.

  In addition, when the result of the lottery determination in the probability variation state is based on a specific probability variation, the symbol determination means may have a possibility of being hit in the corresponding lottery as a reach state with a non-specific symbol. Alternatively, the symbol variation display with a special reach mode that additionally accompanies the effect image suggesting that it is higher may be selected.

  The “special reach mode” mentioned here may have a longer variation time than a normal reach mode and a high reliability for hitting. That is, even if a reach state due to non-specific symbols occurs, it is difficult to give a sense of crisis that if the reliability is low, it will be a hit. In this aspect, by producing a highly reliable reach aspect, it is possible to impress that there is a high possibility of occurrence of hits due to non-specific symbols, and further increase the player's sense of crisis. Enlarge. Thereby, it is possible to further enhance the impression when the end of probability change is avoided. It should be noted that the credibility of the hit occurrence in the non-specific symbol can be further enhanced by performing the variable display in the semi-stop mode after showing the special reach mode.

  You may further provide the log | history holding means which hold | maintains the generation | occurrence | production history of the reach state by the non-specific symbol in a probability fluctuation state. The display control means, when the result of the lottery in the probability variation state is a specific probability change, when the occurrence rate of the reach state due to the non-specific symbol in the predetermined period before the lottery is more than the criterion value The winning symbol combination indicating a specific probability variation may be stopped and displayed after the variable display of the semi-stop mode in the winning symbol combination by the non-specific symbol.

  Here, the “occurrence history” may be stored, for example, as the number of times that the symbol determining means selects the symbol variation mode with the non-specific symbol reach mode during the probability change. The “predetermined period” may be set, for example, as a period for a plurality of symbol changes before the success / failure lottery, or may be set as a time or date before the success / failure lottery. As the “judgment reference value”, for example, an occurrence rate that may reduce a player's sense of expectation or willingness to continue playing in the occurrence frequency of the reach state due to the non-specific symbol may be set empirically or statistically Good.

  According to this aspect, when the occurrence rate of the reach state due to the non-specific symbol is equal to or higher than the determination reference value, the relief effect from the end of the probability change described above is performed. That is, when the probability of jackpots on non-specific symbols during probability change is high, if a reach effect occurs on the non-specific symbols, the player tends to give up continuation of the probability change. In such a case, it is possible to increase the interest of the player and the willingness to continue the game by restoring the sense of expectation for the continuation of the probability variation by displaying the symbol indicating that the probability is a certain probability variation.

  Or you may further provide the log | history holding means which hold | maintains the generation | occurrence | production log | history per specific probability change in a probability fluctuation state. When the result of the lottery determination in the probability fluctuation state is a specific probability variation, the display control means determines that the occurrence rate per specific probability variation in the predetermined period before the success lottery is not less than the criterion value. After the change display of the semi-stop mode with the hit symbol combination by the specific symbol, the hit symbol combination indicating that the hit is a specific probability change may be stopped and displayed.

  Here, the “occurrence history” may be stored, for example, as the number of times that the result of the success / failure lottery by the success / failure lottery unit during the probability change has become a specific probability change. The “predetermined period” may be set, for example, as a period for a plurality of symbol changes before the success / failure lottery, or may be set as a time or date before the success / failure lottery. As the “determination reference value”, for example, an occurrence rate at which the player may feel that the specific probability change is relatively a loss may be set empirically or statistically.

  According to this aspect, when the occurrence rate per specific probability change is equal to or greater than the determination reference value, the above-described relief effect from the end of the probability change is performed. In other words, since a certain probability variation is less profitable than a normal probability variation, the higher the occurrence frequency, the larger the negative image of the player with respect to the certain probability variation. In such a case, it is possible to enhance the player's impression of certain probability variation by revitalizing the expectation to continue certain probability variation by displaying the symbol indicating that it is a certain probability variation. Can be spread.

  It should be noted that any combination of the above-described constituent elements and a conversion of the expression of the present invention between a method, an apparatus, a system, a recording medium, a computer program, and the like are also effective as an aspect of the present invention.

  According to the present invention, it is possible to provide an effect control technique that can further enhance the player's expectation and interest during probability change.

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%.

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

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

  In the normal game after the end of the special game, a variable time shortening game (hereinafter referred to as “time reduction” as appropriate) that is one of the specific games is started. In the variation time shortening game, the variation time of the special symbol and the decorative symbol is shortened from the normal time. The variation time of the special symbol and the decorative symbol is returned to the original variation time after the variation display of a predetermined variation number is performed. 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.

Similarly, each functional block included in the sub-board 104 may be configured such that any one of them is mounted on the main board 102 instead of the sub-board 104.

  The entrance determination means 110 determines whether or not a game ball has entered each winning opening. When receiving the start winning information, the winning determination means 110 determines that the game ball has won the start opening 62, and when receiving the big winning opening winning information, determines that the game ball has won the big winning opening 66, and the general winning is obtained. When the information is received, it is determined that the game ball has won the general winning opening 72. When receiving the passage information, the ball entering determination unit 110 determines that the game ball has passed through the operation port 68.

  The success / failure lottery means 112 accepts a random number value to determine whether or not to shift to a special game that is more advantageous to the player than the normal game when the game ball enters the start port 62. Get as a value. For example, the success / failure lottery value is acquired from a value range from “0” to “65535”. The “random number” in the present application may not be a mathematically generated random number, but may be a pseudo-random number generated by a hardware random number, a software random number, or the like. The success / failure lottery means 112 holds a plurality of success / failure tables to be referred to in the success / failure determination. In the plurality of success / failure tables, the determination result of winning or losing is associated with the winning / losing lottery value, and the success / failure probability is determined according to the associated winning range setting. The success / failure lottery means 112 refers to a success / failure table for determination of success / failure based on a normal probability in normal times, and refers to a success / failure table in which the winning probability is higher than the normal probability when the probability changes. The success / failure lottery means 112 refers to any of the plurality of success / failure tables and determines whether or not the success / failure lottery value is a win. The determination result by the success / failure lottery means 112 is variably displayed in a special symbol form on the special symbol display device 61. In addition, a decorative symbol that shows the determination result by the success / failure lottery means 112 is displayed in a variable manner on the effect display device 60.

  The symbol determination unit 114 determines the stop symbol and the variation pattern of the special symbol to be displayed on the special symbol display device 61 according to the lottery result by the success / failure lottery unit 112. Moreover, the symbol determination means 114 determines the stop symbol of the normal symbol displayed on the normal symbol display device 59 by lottery. The stop symbol is a symbol to be displayed at the end of symbol variation. The symbol determination means 114 holds a symbol range table to be referred to in order to determine a special symbol or a normal symbol stop symbol, or a pattern determination table to be referred to in order to determine a variation pattern.

  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 time is defined for each pattern as an end condition of the symbol variation, and the variation of the special symbol is stopped when the variation time elapses.

  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 continued a plurality of times, and is constituted 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 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 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. In this embodiment, the reach variation pattern such as normal reach that does not involve development in production such as background switching, super reach that enhances the reliability of jackpot including production development by producing a story by a specific character, etc. Is included. 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 the transition to the special game, three symbols such as “777” and “222” 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 “546” 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.

  In the present embodiment, in the case where the result of the lottery determination is a win, the type of stop symbol distinguishes between “probability per win” with certainty after special game and “normal win” without any probable change. That is, odd symbols such as “1”, “3”, “5”, and “7” are set as symbols per probability variation (also referred to as “probability variation”), and as symbols per normal variation (also referred to as “normal symbol”). Even numbers of “2”, “4”, “6”, “8” are set. In this embodiment, the probability variation symbol corresponds to a “specific symbol”, and the normal symbol corresponds to a “non-specific symbol”. Therefore, the decorative symbol is stopped and displayed with a winning symbol combination such as “777” when a probability variation is generated, and is stopped and displayed with a normal symbol winning symbol combination such as “666” when a normal winning occurs. The The player recognizes that there is a high probability of winning if the two stop symbols (also referred to as “Tempai” symbols) in the reach production are likely to vary. Can be recognized. In particular, during probability variation, it can be recognized that the probability variation continuity is high when the symbol pattern is composed of probability variation symbols, and the probability variation continuation confirmation can be recognized when the winning symbol combination is composed of probability variation symbols. On the other hand, the player can recognize that there is a high possibility of normal winning when the tempered symbol resulting from reach production is a normal symbol, and can recognize the occurrence of normal winning when the winning symbol combination is a normal symbol. In particular, during probability variation, it can be recognized that there is a high probability of probability variation termination when the template symbol is a normal symbol, and when the winning symbol combination is a regular symbol, the probability variation termination can be recognized.

  Furthermore, in this embodiment, as a result of the success / failure lottery, a hit with a so-called sudden probability change (corresponding to “special special game”: hereinafter referred to as “surprise accuracy”) in which a probability change without substantial appearance is made occurs. obtain. In other words, when the probability variation due to this suddenness (corresponding to “specific probability variation”: hereinafter referred to as “surprise probability variation”) occurs, the winning prize opening 66 is opened and closed several times (twice in this embodiment) in a very short cycle. Repeatedly, the transition to probability change is performed. Since the opening / closing cycle of the big prize opening 66 is short, the possibility of winning the big prize opening 66 during that period is substantially zero. The probability of jackpot increases. In the present embodiment, “626” or the like (which corresponds to “success symbol combination indicating a specific probability variation”), which is also a tentative symbol based on a normal symbol, as a winning stop symbol combination indicating that the result of the lottery is a winning hit Yes) is set. In order to distinguish the winning stop symbol combination from the unsuccessful stopping symbol combination, the characters “probability change” are displayed together with the stopping symbol when a rush occurs. Details of such effects will be described later.

  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.

Hereinafter, characteristic functions and operations in the present embodiment will be described.
In the present embodiment, the symbol determination means 114 acquires the pattern determination lottery value from a range of “0 to 255”, for example, prior to the special symbol variation display. Based on the pattern determination lottery value and the result of the success / failure lottery by the success / failure lottery means 112, the variation time of the special symbol is determined. The symbol determination means 114 holds a pattern determination table (not shown) including a winning variation pattern and a deviation variation pattern. Each variation pattern is assigned a variation pattern number for identifying the variation pattern. The symbol determining means 114 refers to the winning variation pattern when the result of the lottery is winning, and refers to the losing variation pattern when it is unsuccessful. Then, the variation pattern corresponding to the pattern determination lottery value is selected. Basically, the longer the variation time, the longer it is possible to secure time for various productions such as reach production and its development production. In addition, since the variation pattern of the hit mode performs an effect with higher reliability, the variation time is set to be relatively longer than the variation pattern of the off mode. The symbol determination unit 114 sends the variation pattern number of the variation pattern determined using the pattern determination table and data indicating the stop symbol determined using the symbol range table (not shown) to the effect determination unit 132.

  The effect determining unit 132 holds a pattern table for selecting one of a plurality of variation patterns held by the pattern storage unit 130. Based on the data received from the symbol determining unit 114, the effect determining unit 132 determines the stop symbol of the decorative symbol corresponding to the stop symbol and the variation pattern of the decorative symbol corresponding to the variation pattern number.

  FIG. 4 is a data structure diagram of a pattern table used when the effect determining means determines the variation pattern of the decorative symbol. In practice, there are a wider variety of variation patterns than those shown in the figure, but here, in order to make the explanation easier to understand, only one representative pattern is shown. Actually, each variation pattern is further subdivided and set corresponding to the variation pattern (variation time) of the special symbol, and one of the variation patterns is selected by pattern lottery. To do.

  The effect determining unit 132 uses a pattern table when determining the display pattern of the variable display process. Pattern data indicating the contents of this pattern table is held in the pattern storage means 130. In this pattern table, the result of the lottery win / fail is corresponding to each of the probability variation, normal win, and miss, the reachless pattern that does not go through the reach state, the reach variation pattern that goes through the normal reach as the normal reach mode, and the special reach mode Reach fluctuation patterns through super reach are set respectively. For each probability variation, a variation variation pattern in which the variation is sudden and a non-random variation pattern in which the variation is not sudden are set. In this embodiment, for the sudden fluctuation pattern, a normal sudden fluctuation pattern for performing a normal effect and a sudden special fluctuation pattern for performing a special effect are set. The normality variation pattern is a pattern that is selected only in the normal state of the normal game, and the accuracy symbol is stopped and displayed without reaching. On the other hand, the suspicion special variation pattern is a pattern that is selected only during the probability change of the normal game, and the suspicion symbol is stopped and displayed after being accompanied by the reach in the normal symbol.

  In other words, also in this embodiment, if a big win occurs in the probability variation pattern during probability variation, the probability variation is continued after the subsequent special game, and a game state advantageous to the player called “probability variation chain” is maintained. On the other hand, when a big hit occurs in the normal symbol during the probability change, the probability change ends, and after the special game that follows, it shifts to the normal state. For this reason, when the decorative symbol is stopped and displayed in a normal symbol combination, the player will recognize the end of probability change. In this embodiment, in the special accuracy variation pattern, the reach state combination by the normal symbol (also referred to as “normal symbol template”) is displayed and then the winning symbol combination is displayed. As a result, after the normal symbol temper is performed during the probability change and the end of the probability change is suggested in the effect, a special effect is made that the relief is made by the occurrence of the suddenness. A specific example of this effect will be described later.

  On the other hand, when the result of the winning / failing lottery is other than the winning hit, a normal effect that is not a special effect is performed. That is, in any non-accuracy variation pattern, the winning symbol combination in the probability variation symbol is stopped and displayed. When the reach effect is accompanied, the reach state display (also referred to as “probability variation design template”) is performed with the probability variation symbol. In the normal hit variation pattern, the hit symbol combination in the normal symbol is stopped and displayed. When the reach effect is accompanied, a normal symbol temper is performed before the stop display. When the reach variation pattern is accompanied by a reach effect, the off symbol combination is displayed after the probability variation symbol template or the normal symbol template is performed.

FIG. 5 is a diagram illustrating a screen example of an effect image displayed on the effect display device in the special effect. FIGS. 3A to 3D sequentially show the flow of special effects.
In the display area 200 in the center of the effect display device 60, a decorative symbol 190 composed of three rows of symbols simulating a slot machine game is variably displayed as part of the effect image. The three rows of symbols are displayed so as to rotate on the three rows of reels formed on the virtual drum. FIG. 5A shows a state in which three rows of symbols are displayed in a large variation on the display area 200 during probability change. In addition, in the same figure, when an effective line, that is, a line indicating the result of the lottery (see the alternate long and short dash line) is formed in the center in a mode in which a plurality of symbols positioned on the line are stopped and displayed. However, it goes without saying that a plurality of effective lines may be formed.

  During the probability change of a normal game, as shown in FIG. 5A, the characters “probability change” indicating that are displayed together with the corners of the screen. If a sudden hit occurs during this probability change, the special effect described above is executed. In other words, as shown in FIG. 5B, after the reach effect with the normal symbol (“6” in the figure) is made, for example, the effect of developing into the super reach shown in FIG. The player feels a sense of crisis that the jackpot in the normal symbol, that is, the probability change ends, due to the occurrence of a highly reliable super-reach to the jackpot. In this embodiment, a stunning effect is performed from this state. That is, as shown in FIG. 4D, after the effect display control means 134 stops and displays a predetermined suspicion symbol as the decoration symbol 190, the special game control means 120 opens and closes the big prize opening 66 several times in a short cycle. A special special game is executed. In the illustrated example, a winning symbol combination of “626” is displayed as one of the probable symbols. This special special game ends instantly, but when the special winning opening 66 is closed and the symbol variation is resumed, the state returns to the state shown in FIG. Characters are displayed. Even though the symbols are stopped and displayed in a state where the three symbols are not aligned, the player can recognize that the probability change end has been avoided due to suddenness by displaying the characters “probability change” again.

  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 accordance with the determination result, 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). 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). The symbol determining means 114 determines a stop symbol of the special symbol based on the determination result (S46), and selects a variation pattern of the special symbol (S48). The effect determination means 132 determines the stop symbol combination of the decorative symbols based on the determination result and the special symbol (S50), and selects the variation pattern of the decorative symbol according to the variation pattern of the special symbol (S52).

FIG. 9 is a flowchart showing in detail the processing of S52 in FIG.
The effect determination means 132, if the result of the lottery is a probability change with a certainty (Y in S102, S104, S106), if the current probability is changing (Y in S108), the sudden special variation with the special effects described above Select the pattern table for the pattern. Then, a variation pattern corresponding to the variation time is determined from the pattern table (S110). As a result, after the reach effect accompanied by the normal symbol temper, the winning symbol is stopped and displayed, and the special game control means 120 executes a special special game in which the special winning opening 66 is opened and closed twice in a short cycle. As a result, after the special special game is finished, the state is shifted to the probability change state again. If the probability change is not underway in S108 (N in S108), the normality variation pattern for suddenly changing the suddenness symbols without selecting the reach state is selected (S112).

  On the other hand, when the result of the lottery result is a non-accurate probability variation hit (N in S106), a non-accident variation pattern is selected (S114). A hit variation pattern is selected (S116). If the winning / losing lottery is missed (N in S102), a missed fluctuation pattern is selected (S118).

  FIG. 10 is a flowchart showing in detail S16 in FIG. First, if the big prize opening 66 has not been opened (N in S70), the production display control means 134 starts the special game production process (S72), and the open / close control means 124 opens the special prize opening 66 (S74). ). If the big winning opening 66 has been opened, S72 and S74 are skipped (Y in S70). When the predetermined opening time has elapsed since the grand prize opening 66 was opened (Y in S76), or the opening time has not elapsed (N in S76), there are nine or more game balls to the big winning opening 66 When the player has entered the ball (Y in S78), the opening / closing control means 124 closes the special winning opening 66 (S80). If the opening time has not elapsed (N in S76) and the number of balls entered into the grand prize winning opening 66 has not reached nine or more (N in S78), the processing after S80 is skipped and the flow of S16 Exit.

  If the number of rounds of the unit game has reached 15 after closing the special winning opening 66 in S80 (Y in S82), the effect display control means 134 ends the effect processing of the special game (S84), and the special game control means 120 ends the special game (S86). If the number of rounds has not reached 15 (N in S82), 1 is added to the number of rounds and the flow of S16 is terminated (S90).

  As described above, in the pachinko gaming machine 10 of the present embodiment, when the result of the winning / failing lottery during the probability change is a sudden hit, the reach effect is intentionally made with the normal symbol, and the possibility of the probability change end is likely. I suggest it in production. In this way, after the player feels intimidated, the special special game is performed to avoid the end of the probability change. By creating such a production gap, it is possible to give an impact to the player and further enhance its interest. In addition, players generally have the impression that accuracy during a change is a loss, so that the effectiveness of the production can be recognized by making a sudden gap in the direction of relief from the end of the change. Can do. As a result, the range of production is expanded.

  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 also within the scope of the present invention. is there.

  In the above embodiment, in the pattern table shown in FIG. 4, the presence / absence of reach changes depending on whether or not the probability change is in progress, but the pattern that moves suddenly without reach during the probability change or reach during the non-probability change. It is also possible to include a pattern that transitions with accuracy.

  Although not described in the above embodiment, in the special effect, not only the reach effect by the normal symbol, but the effect that the end of the probability change is confirmed by pseudo-stopping the hit symbol by the normal symbol is performed, and then You may make it perform the relief on the production by suddenness. Specifically, for example, a winning symbol combination “666” in a normal symbol is pseudo-stopped and displayed between FIGS. 5 (c) and (d). At this time, the central symbol “6” is variably displayed in a semi-stop manner in which the central symbol “6” is continuously finely moved to the front and rear positions in the fluctuation direction so as not to stop the fluctuation itself. Then, it may be replaced with a stop symbol “626” shown in FIG. As a result, the production gap given to the player can be further increased, and the impact can be further increased.

  On the other hand, if a special effect such as relief from the end of probability change as described above is frequently performed, the impact and appreciation of the effect may be reduced. Therefore, timing restrictions and adjustments may be provided for execution of the special effects. For example, the frequency of occurrence of the normal symbol tempering during probability change may be managed, and special effects may be performed when the frequency of occurrence increases. Specifically, the sub-board 104 may further include a history holding unit that holds the occurrence history of the reach state by the normal symbol. The occurrence can be determined based on the determination result of the stop symbol and the variation pattern by the symbol determining means 114 or the effect determining means 132. The occurrence history can be held by counting the number of times the reach variation pattern based on the normal symbol is selected by the effect determining means 132. For example, when the reach effect by the normal symbol is equal to or more than the first determination reference number in the most recent predetermined number of symbol variations, the effect display control means 134 is in a semi-stop mode with the hit symbol combination by the normal symbol. After the variable display, the winning symbol combination due to suddenness may be stopped and displayed. Or after performing display which develops to super reach with the normal symbol template, the winning symbol combination due to suddenness may be stopped and displayed. At that time, the change display of the semi-stop mode with the hit symbol combination by the normal symbol may be performed between the change display of the super reach and the stop display of the hit symbol combination by the suddenness.

  Or you may make it manage the frequency of occurrence of the accompaniment which does not accompany the special effect, and perform a special effect when the frequency of occurrence increases. The sub-board 104 may further include a history holding unit that holds a history of occurrence of suddenness. The occurrence can be determined based on the determination result of the variation pattern by the symbol determining means 114 or the effect determining means 132. The occurrence history can be held by counting the number of times that the dramatic variation pattern is selected by the effect determining means 132. For example, the effect display control means 134 performs a semi-stop mode with a winning symbol combination based on a normal symbol when the stunning effect without a special effect is equal to or more than the second determination reference number of times within the most recent predetermined symbol variation number of times. After the fluctuation display, the winning symbol combination due to suddenness may be stopped and displayed. Or after performing display which develops to super reach with the normal symbol template, the winning symbol combination due to suddenness may be stopped and displayed. At that time, the change display of the semi-stop mode with the hit symbol combination by the normal symbol may be performed between the change display of the super reach and the stop display of the hit symbol combination by the suddenness.

  In the above embodiment, the example in which the ball game machine of the present invention is configured as the first type pachinko game machine is shown. However, the game machine capable of executing a plurality of functions of the first type pachinko game machine in series or in parallel. For example, it may be configured as another gaming machine including the function of the first type pachinko gaming machine.
