Description

  The present invention relates to a ball game machine such as a pachinko game machine, and more particularly to a technique for controlling screen display contents in a ball game machine.
Conventionally, among the various ball game machines, a so-called first type pachinko game machine is used while changing a plurality of symbols in a display area such as a liquid crystal display provided substantially at the center of the game board. Display (hereinafter, such display is referred to as “symbol change” or “change display”). This gaming machine shifts to a special game called so-called jackpot where more prize balls can be obtained than a normal game when a combination of symbols when a plurality of rows of symbol variations are stopped becomes a specific mode. It is known as a thing (for example, refer patent document 1). The variable display of symbols in the display area is not limited to simply displaying multiple symbols in a variable manner, but the time required for variable display is usually reduced when one more symbols are aligned, such as a so-called reach image. For example, an effect is made to increase the player's expectation, such as making it longer. In addition, the player's expectation is enhanced by controlling the specific game such as the probability variation that changes the probability of transition to special games by giving the story to the variation display using characters on the image such as symbols Yes.
JP 2003-230714 A
  A plurality of types of reach production using reach images are prepared in order to improve the production effect. In addition, reach productions with various fluctuation times are prepared to make the production contents diverse. Conventionally, the design time (variation time) of the decorative symbol including the reach effect is the same as the variation time of a symbol called a special symbol determined by a lottery executed when a game ball enters the start opening. It has been decided. Then, the reach effect of the variation time corresponding to the variation time of the special symbol is selected from the selection table. One of the functions of reach production is to have a sense of expectation for jackpots. The longer the reach variation time of the reach production, the easier it is to have a sense of expectation for the win. In the case of the big win, the reach production of the long variation time is often selected rather than the reach effect of the short variation time. On the other hand, if only a reach effect with a long variation time is executed in a big hit, the reliability of the reach effect is lowered. In addition, there is a possibility that the idea of not being hit when a reach effect with a short variation time is executed. Therefore, the creation method of the selection table is devised so that various reach effects can be selected. However, as described above, the actual situation is that it is easy to select a long variation time for winning and a short variation time for deviation. The design jackpot probability in pachinko machines varies depending on the model, but is often about 1/300 to 1/400 at a low probability. As a result, even if the reach effect is executed, the number of cases of “out” must be increased. Therefore, a reach effect that is rarely selected is inevitably generated. As a result, some of the reach productions that have been made are not fully utilized without touching the player's eyes at all. In order to prepare a reach production, there is a desire to let the players touch the eyes and to give all the players an opportunity to see such a reach production.
  The present invention has been made in view of these problems, and the purpose of the present invention is to make it possible to show the prepared reach performance pattern uniformly to the player and to make full use of the reach performance to perform the game performance. The object is to provide a ball game machine that can be used.
  In order to solve the above-described problems, a ball game machine according to an aspect of the present invention includes a game board on which a game area is formed, a start prize opening provided at a predetermined position in the game area and into which a game ball can enter. , The correspondence between the lottery means for executing the lottery triggered by the game ball entering the start winning opening, and the variation time when the special symbol indicating the result of the lottery is displayed and the result of the lottery is determined A variation table is held, a variation time of a special symbol is selected with reference to the variation table, a symbol determination means for determining a stop symbol to be displayed when the variation of the special symbol is stopped, and a lottery result are displayed in an effect An effect display device, an effect pattern storage means for holding a plurality of types of effect patterns in which a mode from start to stop of an effect image to be variably displayed on the effect display device during the change of the special symbol is determined, and an effect pattern An effect determining means for selecting an effect pattern corresponding to the variation time of the special symbol from a plurality of effect patterns stored in the storage means, and an effect for causing the effect display device to variably display an effect image corresponding to the effect pattern selected by the effect determining means. Display control means, and special game control means for executing a special game that is more advantageous to the player than the normal game after the change of the special symbol is stopped when the lottery result is a win. The effect pattern storage means includes a plurality of isometric reach effect patterns having substantially the same change time as the effect pattern of the reach mode that becomes a win when one more symbols are arranged. The symbol determining means includes a special variation time in which any of the isometric reach effect patterns can be linked during the variation as the variation time of the special symbol. When the special variation time is selected by the symbol determining means, the effect determining means selects the current isometric reach effect pattern based on the history information of the isometric reach effect pattern selected in the past, and isometric reach reach pattern So that the appearance rate falls within a predetermined range.
  Here, the variation table of the symbol determination means includes a special variation time and a variation time different from the special variation time. In addition, the effect pattern storage means includes a plurality of isometric reach effect patterns and effect patterns having varying times different from the varying times of the isometric reach effect patterns. There may be one special variation time held in the variation table, or a plurality of special variation times as long as the variation times are substantially the same. In addition, if the isometric reach production pattern has substantially the same variation time as the variation time of the special variation time, it is preferable that the production contents of each isometric reach production pattern are different from each other. For example, the background of the production may be different, the characters appearing in the production may be different, or the story may be different. Then, the same superiority or inferiority as the jackpot reliability that has been represented by the length of the fluctuation time in the related art may be given by varying the contents of the production of each isometric reach production pattern. Alternatively, a plurality of isometric reach effect patterns with similar effect contents may be prepared, an isometric reach effect pattern with a lot of similar effect contents may be subordinated, and an isometric reach effect pattern with less similar effect contents may be determined as a superior classification. .
  According to this aspect, when the special variation time is selected as the variation time of the special symbol by the symbol determining means, the effect determining means can select any of a plurality of isometric reach effect patterns prepared. At this time, by performing selection based on the history of the isometric reach effect pattern selected in the past, the appearance rate of the isometric reach effect pattern can be adjusted to be within a predetermined range. That is, the effect determining means selects the isometric reach effect pattern while adjusting the appearance rate, so that it is possible to avoid the occurrence of the isometric reach effect pattern that is not executed or the isometric reach effect pattern that is excessively executed. In addition, even when the reach performance pattern is given reliability or superiority in production, the reach production pattern can be selected regardless of the reliability or superiority. As a result, the prepared reach production pattern can be evenly touched by the player, and the reach production pattern can be fully utilized.
  The effect determining means selects the effect pattern according to the result of the lottery, and when the same isometric reach effect pattern is continuously selected a predetermined number of times for the isometric reach effect pattern, the next equal length reach effect is selected. When the lottery result corresponding to the pattern selection is a win, select the same isometric reach effect pattern that has been selected a predetermined number of times, and when the lottery result is out of the way, continue for a predetermined number of times You may select the isometric reach production pattern different from the selected isometric reach production pattern. When the special variation time is selected, the effect determining means can select any effect pattern from the isometric reach effect patterns. For example, in the selection so far, the same isometric reach effect pattern is selected, for example, twice in succession, and if both are off effects, the same isometric reach effect pattern is selected if the current lottery wins. Produce a hit. That is, in the past, the same effect was missed, but if the miss has continued for a predetermined number of times, the same effect is given as a premier. As a result, it is possible to provide a new effect that gives a sense of expectation by using it as a successful effect even when the reach condition that is expected to deviate from experience is met. Further, when the current variation is off, it is possible to avoid a player who has fallen off with the same effect pattern by executing an isometric reach effect pattern different from the past effect pattern. Furthermore, only the player himself / herself can know whether or not the same isometric reach performance pattern is continuous. Therefore, the player comes to confirm the continuity of reach production, and can play for a long time with the same gaming machine. As a result, it is possible to contribute to an improvement in the game machine fixing rate of the player.
  The effect determining means may select the isometric reach effect pattern so that the appearance rate of the isometric reach effect pattern stored in the effect pattern storage means is within a predetermined range while the effect pattern is selected a predetermined number of times. . For example, when 20 types of equal length reach effect patterns are prepared, all 20 types of equal length reach effect patterns are selected at least once before the number of times of selecting the effect pattern reaches 1000 times. Select while adjusting the appearance rate. In this case, with reference to the appearance rate of each equal length reach effect pattern, for example, the selection may be made sequentially from the one with the smallest number of selections. Further, the selection of the isometric reach effect pattern that is selected over a predetermined number of times may be temporarily suspended. As a result, if the display of the production pattern is performed a predetermined number of times, it becomes possible to display all the prepared isometric reach production patterns, and the player can be provided with the production that effectively uses all the prepared isometric reach production patterns. .
  The effect display control means may display information on the isometric reach effect pattern selected in the past on the effect display device with reference to the history information of the isometric reach effect pattern selected by the effect determining means. The history information may be always displayed at a predetermined position of the effect display device, or may be displayed only when the customer waiting screen is displayed. According to this aspect, when the isometric reach effect patterns having the same contents are continuous, it is possible to provide a new game that makes it possible to expect the next time with the continuity. In addition, a new reference when the player selects a gaming machine can be provided by the history of the production pattern.
  The isometric reach production pattern may be a pattern in which the variation time is longer than a predetermined time among the production patterns in the reach mode included in the production pattern storage means. There is a recognition that the reliability for the jackpot in the conventional reach production is higher as the variation time is longer. Therefore, a reach manner shorter than the predetermined time and a reach manner longer than that are provided, and the equal length reach effect pattern is applied to the reach manner longer than the predetermined time. As a result, differentiation can be made in the reach production, and the difference in reliability due to the length of the variation time can be provided as in the conventional case. Since the reach mode in which the variation time is shorter than the predetermined time is often selected when the special symbol is out of mode, there is little possibility that an effect pattern that is not selected will occur. Even if the player is continuously selected and deselected, the player recognizes that the reach performance with a short variation time is low in reliability, and therefore, the possibility of giving a sense of incongruity is low. On the other hand, the isometric reach effect pattern whose variation time is longer than the predetermined time is selected so as to be within a predetermined appearance rate based on the history information. The isometric reach effect pattern, which is recognized as having a longer variation time than the predetermined time and high reliability, is adjusted for its appearance rate, so that it is possible to make all the prepared isometric reach effect patterns appear. It is possible to provide the player with an effect that effectively uses the isometric reach effect pattern.

  The variation table 204 stores a plurality of types of variation patterns in which variation modes from the variation start to the stop when the special symbol indicating the lottery result of the success / failure lottery means 112 is variably displayed. 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 variation table 204 includes a special variation time and a general variation time shorter than the special variation time as the variation time of the special symbol. The special variation time is a variation time of a length in which any of a plurality of effect patterns (equal length reach effect patterns described later) used when the decorative symbol is stopped with a reach effect. The general variation time is a variation time used when the symbol is stopped without a reach effect. FIG. 4 shows an example of the variation table 204 used when determining the variation time of the special symbol. The special variation time is set to 60 seconds, for example. The general variation time is set to 8 seconds or 10 seconds, for example. When the lottery by the success / failure lottery means 112 is successful, the symbol effect is accompanied by a reach effect, so the symbol determining unit 114 selects a special variation time of 60 seconds with a probability of 100%. Further, when the lottery means 112 is not selected, the symbol determination means 114 selects a general fluctuation time of 8 seconds or 10 seconds or a special fluctuation time of 60 seconds. In the example of FIG. 4, the symbol determination means 114 selects the general variation time of 8 seconds with a probability of 30%, for example, and selects the general variation time of 10 seconds with a probability of 40%, for example. Further, a special variation time of 60 seconds is selected with a probability of 30%, for example.
  In addition, although it demonstrates in detail in another Example, in the conventional reach production, there exists recognition that the reliability is so high that variation time is long. As a result, as shown in FIG. 4, if the variation time of the special symbol corresponding to the variation time of reach production is all the same variation time of the same variation time, the reliability can not be expressed by the variation time, May cause a sense of incongruity. Therefore, the variation time of the special symbol corresponding to the reach effect is divided into a variation time shorter than the predetermined time and a variation time longer than that, and the variation time longer than the predetermined time is set as the special variation time. Thereby, it is possible to provide a difference in the variation time of reach production, and it is possible to provide the reliability due to the difference in the variation time as in the conventional case.
  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 in 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. The fluctuation pattern includes the normal pattern for displaying a normal out symbol, the outreach pattern for displaying a dismissed symbol after reaching a big win if one more symbols are aligned, and the jackpot symbol via a reach state. A hit reach pattern for displaying 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. In this embodiment, the patterns when reaching the reach state are all equal length reach effect patterns with substantially the same variation time. 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. Therefore, in the case of the present embodiment, the pattern storage means 130 changes the variation pattern without reach effect in the same 8 seconds or 10 seconds as the general variation time of the special symbol and the variation with reach effect in the same variation time as 60 seconds. A plurality of patterns (equal length reach production patterns) are held. When the special variation time is selected by the symbol determining means 114, any reach pattern can be linked during the variation of the special variation time.
  In this embodiment, the equal length reach effect pattern held by the pattern storage unit 130 has the same variation time. Therefore, differentiating the reliability with respect to the jackpot of each equal length reach production pattern is aimed at according to the production content. For example, the jackpot reliability when the variably displayed by changing the background image or the background color is expressed. Further, the reliability may be differentiated by changing the type and number of characters appearing and the story of the production. In the case of differentiating with the story of the production, for example, the story may be changed twice or three times or a cut-in image may be inserted while the variation of the decorative pattern to be displayed together with the reach production is continued. Further, it may be emphasized that the variation is different from other variations by making the effect image and the decorative design appear to be temporarily stopped and then varying again.
  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 determining unit 132 includes a history holding unit 206 that holds which is the equal length reach effect pattern when the equal length reach effect pattern is selected. The effect determining means 132 updates the history holding means 206 every time an isometric reach effect pattern is selected, and refers to the updated history holding means 206 when determining the isometric reach effect pattern. The effect determining unit 132 can intentionally change the appearance rate of the equal length reach effect pattern by determining the next equal length reach effect pattern to be selected with reference to the history holding unit 206. For example, when a specific isometric reach effect pattern is frequently selected, another isometric reach effect pattern can be selected so as to reduce the appearance rate of the isometric reach effect pattern. Conversely, when the same isometric reach production pattern is intentionally selected, it can be easily selected. For example, let us consider a case where, in the selection so far, the effect determining means 132 selects the same isometric reach effect pattern, for example, twice in succession, and all of them are off effects. In such a case, the player has the impression that the reliability of the reach performance pattern is low. Therefore, if the same isometric reach effect pattern is continuously deviated a predetermined number of times, if the next isometric reach effect pattern is selected, the same isometric reach effect pattern is selected. As a result, it is possible to provide a new effect in which even a reach effect that is expected to deviate from experience is used as a win effect and a sense of expectation is provided when predetermined conditions are met. In addition, even if there are consecutive divergences in the same production, it is possible to prevent the player from diminishing the willingness to play. In addition, if the selected isometric reach production pattern is different after the same isometric reach production pattern is repeated a predetermined number of times, if the same length reach production pattern that is different from the previous one is selected, the same production will be missed again. It is possible to avoid giving the player the impression that
  In addition, the player has a sense of expectation for the next reach production if the discontinuation continues in the same isometric reach production pattern. In this case, only the person who actually plays the game knows whether or not the deviation is continued for a predetermined number of times with the same isometric reach performance pattern. Therefore, since the player can play the same gaming machine for a long time, it is possible to contribute to improvement of the gaming machine fixing rate of the player. The history information held by the history holding unit 206 may be displayed using an effect display device 60 or the like, as shown in FIG. In the example of FIG. 5, a history display area 210 is formed at the lower center of the effect display device 60. In the example of FIG. 5, it is shown that the first and second reach production is “lightning reach” with lightning motif, and the third reach production is “snowman reach” with snowman motif. . The player confirms the history information displayed in the history display area 210 so that the reliability of “lightning reach” so far is low, but when “lightning reach” is displayed next time, the reliability is reduced. Becomes very aware of it. In this way, when the same isometric reach production pattern is continuous, it is possible to provide the player with a sense of expectation that it may be hit next time due to the continuity. Moreover, a new reference when the player selects a gaming machine can be provided by the effect pattern. Thus, in the past, the reliability of the reach effect was preset in the reach effect itself, but by selecting the reach effect according to the display history of the reach effect as in this embodiment, The concept of fixed reliability is eliminated and game playability can be improved. The history information may be always displayed at a predetermined position of the effect display device 60, or may be displayed only when the customer waiting screen is displayed.
  Further, the effect determining unit 132 includes an appearance rate holding unit 208 that holds the appearance rate of the isometric reach effect pattern. The appearance rate holding means 208 is updated each time an isometric reach effect pattern is selected. When selecting the isometric reach effect pattern, the effect determining unit 132 preferentially selects, for example, an isometric reach effect pattern having a low appearance rate while referring to the appearance rate holding unit 208. As a result, it is possible to avoid an isometric reach effect pattern that is difficult to select. Further, the effect determining unit 132 selects the isometric reach effect pattern so that the appearance rate of the isometric reach effect pattern stored in the effect pattern storage unit is within a predetermined range while the effect pattern is selected a predetermined number of times. be able to. The effect determining means 132 selects the isometric reach effect pattern while adjusting the appearance rate so that the appearance rate of each equal length reach effect pattern does not become “0%” while selecting the effect pattern 1000 times. By making such a selection, it is possible to avoid a state in which a specific isometric reach production pattern is not selected forever. As a result, if the effect pattern is selected a predetermined number of times, it is possible to execute all of the prepared isometric reach effect patterns, and a game effect that effectively utilizes the isometric reach effect pattern can be achieved. Further, if the predetermined number of times of fluctuation is used, all prepared reach effects can be executed, so that it is possible to provide the player with a game form in which all reach effects are viewed.
  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.
  FIG. 6 is a flowchart showing a basic operation process in the pachinko gaming machine. First, processing is performed when a 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 in S34 of FIG.
  First, the success / failure lottery means 112 determines whether or not the lottery value read from the hold control means 116 is successful (S50). If the game is in the probability variation game, the success / failure determination table 200 includes the probability change success / failure table, and if it is not in the probability variation game, the success / failure determination is made. If it is a big hit (Y of S52), the special game control means 120 turns on the special game flag (S54). When the special game flag is on, the special game is executed after the end of the change.
  Furthermore, if it is a probability change hit (Y in S58), the specific game execution means 122 turns on the probability change flag (S60). If it is a normal hit (N in S58), the probability variation flag is turned off (S62). When the probability variation flag is on, the probability variation game is executed from the beginning of the variation following the variation.
  If the winning lottery is out (N in S52), the special game control means 120 turns off the special game flag (S56).
  Subsequently, the symbol determining unit 114 determines the variation time of the special symbol with reference to the variation table 204 based on the determination result (S100), and further determines the stop symbol of the special symbol with reference to the symbol range table 202. (S102). The determined special symbol variation time and stop symbol data are transmitted to the main display control means 118 and the effect determination means 132.
  In the effect determining means 132, when the received variation time of the special symbol is the special variation time (Y in S104), the history information of the equal length reach effect pattern selection in the history holding means 206 is referred to (S106). If the same isometric reach effect pattern was selected in the previous selection of the equal length reach effect pattern last time (Y in S108), and if the result of the current lottery is a big hit (Y in S110), This time, the same isometric reach production pattern is selected (S112). By making such a selection, if the same reach production pattern continues after a predetermined number of times, for example, twice, it is possible to produce an effect of making a big hit with the production pattern that has been believed to have low reliability until now. . In other words, it is possible to make the player think that a performance pattern that has been thought to be “not coming” because the reliability of the jackpot hitherto is low is now “come”. As a result, various impressions can be given to the isometric reach production pattern, and the game performance can be improved.
  On the other hand, if the result of the current lottery is out of place (N in S110), an isometric reach effect pattern having a content different from the previous time is selected (S114). By making such a selection, it is possible to avoid giving the player the impression that the player has continuously deviated with the same reach performance pattern, and it is possible to avoid a decrease in the player's willingness to play.
  In S108, when the same isometric reach effect pattern is not continuously selected (N in S108), the effect determining unit 132 causes the appearance rate of the isometric reach effect pattern held in the appearance rate holding unit 208 to appear. (S116). The effect determining unit 132 selects, for example, an isometric reach effect pattern having the lowest appearance rate (S118). For example, the effect determining means 132 selects the appearance pattern of each equal length reach effect pattern while adjusting the appearance rate of each equal length reach effect pattern so that the appearance rate of each equal length reach effect pattern does not become “0%” while selecting the effect pattern 1000 times. . By making such a selection, it is possible to avoid a situation in which a specific isometric reach production pattern is not selected forever. As a result, if the player selects an effect pattern a predetermined number of times or more, it becomes possible to see all reach effects prepared for improving the effect, and the game performance is improved. Moreover, since all the prepared reach effects can be shown to the player, the reach effects can be effectively utilized.
  When the effect pattern is determined, the effect determining unit 132 updates the history holding unit 206 and the appearance rate holding unit 208 based on the selected isometric reach effect pattern (S120). On the other hand, when the special variation time is not selected in S104 (N in S104), the effect determining unit 132 selects an effect pattern that does not accompany the reach effect (S122). Then, when the effect pattern is determined, the effect determining means 132 determines the stop symbol of the decorative symbol based on the result of the special symbol determination and ends this flow (S124).
  FIG. 9 is a flowchart showing in detail the special game control process in S16 of FIG.
  A special game is a game that is executed after a symbol change when the winning or failing lottery is won and the special game flag is turned on. First, if the special winning 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 winning entry 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). When it is a winning hit (Y in S92), the specific game executing means 122 sets a probability changing success / failure table as a winning / failing table for the winning / failing lottery (S94), and when it is a normal winning (N in S92), An uncertain change determination table is set (S96). In the case of a normal hit, the specific game execution means 122 starts a variation shortening game.
  If the number of rounds 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-described embodiment, an example has been shown in which all the reach effects are equal length reach effect patterns. In this case, since the reach performances all have the same variation time, the difference in reliability with respect to the big hit cannot be expressed due to the length of the variation time as in the conventional case, which makes the player accustomed to the conventional gaming machine feel uncomfortable. There is a case. Therefore, a reach manner shorter than the predetermined time and a reach manner longer than the predetermined time are provided, and the equal length reach effect pattern is applied to the reach manner longer than the predetermined time to provide the reliability due to the difference in the variation time. The reach mode shorter than the predetermined time corresponds to the “normal reach” in the past, and the reach mode longer than that corresponds to the “super reach” in the past. FIG. 10 is an example of the variation table 204 used when determining the variation time of the special symbol. The special fluctuation time is set to 90 seconds, for example. Further, the general variation time is set to, for example, 8 seconds or 10 seconds in a manner in which no reach effect is attached, and is set to, for example, 20 seconds, 25 seconds, or 30 seconds in a manner in which a reach effect (normal reach) is attached. When the lottery by the success / failure lottery means 112 is successful, the symbol effect is accompanied by a reach effect, and therefore the symbol determining means 114 selects one of the fluctuating times of 20 seconds, 25 seconds, 30 seconds, and 90 seconds. The selection probabilities are, for example, 10%, 15%, 25%, and 50%. If the lottery means 112 is not selected, the symbol determining means 114 may have a general variation time of 8 or 10 seconds without a reach effect, a general change time of 20 to 30 seconds with a normal reach effect, or 90 seconds. Select a special variation time. In the example of FIG. 10, the symbol determination means 114 selects the general variation time of 8 seconds, for example, with a probability of 30%, for example, and the general variation time of 10 seconds, for example, with a probability of 40%. Further, the general variation time with reach of 20 seconds is selected with, for example, 12%, the general variation time with reach of 25 seconds is selected with, for example, 8%, and the general variation time with reach of 30 seconds is selected with a probability of, for example, 6%. Further, a special variation time of 90 seconds is selected with a probability of 4%, for example.
  FIG. 11 is a flowchart for explaining the operation of selecting an effect pattern when the change time corresponding to the reach effect pattern is divided into a special change time and a general change time. This flowchart is replaced with S120 of the success / failure determination process (S34) shown in FIG. Therefore, only the part to be replaced will be described here, and the other steps shall refer to the description of FIG.
  In S104, when the success / failure lottery means 112 has not selected the special change time as the change time of the special symbol (N in S104), the effect determining means 132 confirms whether or not the selected change time is for reach effect (S200). Y). That is, when the success / failure lottery means 112 has selected a variation time of 20 seconds to 30 seconds, the effect determination means 132 is configured with a variation time corresponding to the variation time of the special symbol determined by the success / failure lottery means 112. A reach production pattern for normal reach is selected (S202). On the other hand, in S200, when the selected variation time is not for the reach effect (N in S200), the effect determining means 132 selects the effect pattern without the reach effect (S204). After determining the effect pattern, the effect determining unit 132 determines the stop symbol of the decorative symbol based on the lottery result of the success / failure lottery unit 112 and ends this flow (S124).
  Thus, by dividing the variation time of the reach production pattern into the special variation time and the general variation time, it is possible to express the reliability for the big hit by the variation time of the reach production as in the past. That is, it is possible to give the player the same impression that normal reach with a short variation time has low jackpot reliability and super reach with a long variation time has high reliability. It should be noted that the general variation time with reach production (with a relatively short variation time of 20 to 30 seconds) is prepared because it is easy to be selected when the result of the lottery means 112 is wrong. The inconvenience that something difficult to appear in the reach production pattern for normal reach is less likely to occur. On the other hand, while the reliability to the jackpot is high, the reach production with a long variation time (the isometric reach production pattern in this embodiment), which has been considered to have a low appearance rate, is prepared because the appearance rate is adjusted. All isometric reach production patterns can be displayed evenly, and all isometric reach production patterns can be used for production. In the same length reach production pattern as in the example described above, it is preferable from the viewpoint of improving the reach production effect that the reliability is provided according to the content of the production and the hit reliability is changed among the isometric reach production patterns.
  In the present embodiment, a game machine that has been conventionally referred to as a “type 1 pachinko game machine” has been described as an example. However, the present invention can be applied to any model as long as it performs a reach effect using symbols. For example, a multi-function machine in which a plurality of first-class pachinko gaming machines are merged, a multi-function machine in which the first-class pachinko gaming machines are conventionally combined with the gaming characteristics of a second-class pachinko gaming machine, etc. The same effect can be obtained.

    Effect pattern storage means for holding a plurality of types of effect patterns in which a mode from start to stop of the change of the effect image to be variably displayed on the effect display device during the change of the special symbol is defined;
    Effect determining means for selecting an effect pattern according to the variation time of the special symbol from a plurality of effect patterns stored in the effect pattern storage means;
    Effect display control means for variably displaying the effect image corresponding to the effect pattern selected by the effect determining means on the effect display device;
    When the result of the lottery is a win, special game control means for executing a special game that is more advantageous to the player than the normal game after the change of the special symbol is stopped,
    With
    The effect pattern storage means includes a plurality of normal reach effect patterns having different variation times of the special symbol as the effect pattern of the reach mode that becomes a win when one more symbols are aligned, and the variation of the special symbol than the normal reach effect pattern Including a plurality of isometric reach production patterns that are long in time and substantially the same in variation time,
    The plurality of isometric reach production patterns are defined in the variation table such that the probability of winning the lottery result is higher than the plurality of normal reach production patterns, and the probability that the lottery result is successful. A certain degree of reliability is defined according to the production contents for each isometric reach production pattern,
    In the plurality of normal reach production patterns, the correspondence between the variation time of the special symbol and the result of the lottery is changed so that the variation time of the special symbol becomes longer as the probability of winning the lottery result becomes higher. Set on the table,
    The symbol determining means includes, as the variation time of the special symbol, a special variation time in which any of the isometric reach effect patterns can be interlocked during the variation,
    When the special determining time is selected by the symbol determining means, the effect determining means selects the current isometric reach effect pattern based on the history information of the isometric reach effect pattern selected in the past, and isometric While correcting the appearance rate of the reach production pattern to fall within a predetermined range and selecting the production pattern according to the result of the lottery, the same isometric reach production pattern is continuously repeated a predetermined number of times for the isometric reach production pattern. If the result of the lottery corresponding to the selection of the next isometric reach effect pattern is a win, the same isometric reach effect pattern that is selected in succession the predetermined number of times is selected. When the result of the lottery is selected and the result is out of place, the isometric reach effect pattern different from the isometric reach effect pattern selected continuously for the predetermined number of times. Pinball game machine and selects the down.
