BACKGROUND OF THE INVENTION
  The present inventionSlot machine as a gaming machineEspecially for playersNaSpecial gaming stateThe possibility of flag establishmentWith a certain level of confidenceFor noticeIt is related to the improvement of what performs the game production.
[0002]
[Prior art]
  Recent gaming machines are equipped with a microcomputer (microcomputer) and perform a lottery lottery using a random number table, etc. If the lottery is a jackpot, it is advantageous for the player apart from the normal gaming stateNaA special gaming state is created. For example, in the case of a pachinko machine, a lottery is performed when a hitting ball is won at the start winning opening, and at the same time, three symbol display portions of a variable display device including a liquid crystal display, a cathode ray tube or a rotating reel provided at the center of the game surface. A plurality of symbols are variably displayed, and if the lottery is a big win, after stopping and displaying with a combination of specific symbols, for example, a large winning opening is opened for a certain period of time to make it easier for a hit ball to win.
[0003]
  In this type of pachinko machine, for example, as disclosed in Japanese Patent Application Laid-Open No. 9-99144, in order to increase the interest of the game, when the lottery result is displayed as a combination of three symbols in the variable display device Even when the lottery is not a big win, a reach state where a combination of specific symbols is aligned at a predetermined rate when the symbols are stopped and displayed on the first symbol display portion and the second symbol display portion is generated, and Various reach patterns, such as super reach, are created by making a difference in the fluctuation speed and fluctuation time from the reach state until the symbol stops at the third symbol display section. The probability of becoming, that is, reach reliability.
[0004]
[Problems to be solved by the invention]
  However, the reach pattern is usually limited to several types because of the relationship with the memory capacity of the microcomputer installed in the pachinko machine, and the reach reliability is generally constant. If you repeat the game, you will get tired of watching it, and you will lose the fun of the game. As a result, there was a problem that it was inferior in customer attraction and was discarded in a short business period. In short, the content of the reliability announcement of the game effect such as reach in the gaming machine needs to be easily understood by the player, but there is a conflicting problem that if it becomes clear in a short period of time, it will not last long as a gaming machine.
[0005]
  On the other hand, in the above publication (Japanese Patent Laid-Open No. 9-99144), the selection rate of each reach pattern (this selection rate is inversely related to the reach reliability) when the lottery is not a big win is changed according to the gaming state. However, in this case, when the lottery is not a big hit, the game state is subdivided and the selection rate of each reach pattern is changed according to each game state, so the production program becomes complicated, There is a drawback that the burden on the capacity of the microcomputer becomes large.
[0006]
  The present invention has been made in view of the above-mentioned various points, and the problem is to diversify the effect for the reliability notification of the game effect such as reach without increasing the load on the capacity of the microcomputer. A game machine that is rich in gaming and can last longAs slot machineIs to provide.
[0007]

[0016]
  FIG. 3 is a flowchart showing the control contents of the pachinko machine A by the pachinko machine main body control unit 20 (specifically, the CPU 21), and the control contents will be described below according to this flowchart.
[0017]
  First, after waiting for a pachinko ball to win the start winning opening 15 in step S1, a big hit lottery is performed in step S2. This lottery uses the random number generator 24 to win only “7” of the jackpot lottery random numbers (0 to 199), and the jackpot probability is 1/200. Further, in this lottery, a reach is generated when the random number is “0 to 20”, the reach occurrence probability is 21/200, and the lose reach probability is 20/200, that is, 1/10.
[0018]
  In step S3, it is determined whether or not reach has occurred as a result of the lottery. If this determination is YES, the pattern table by reliability selected and set in steps S10 and S11 described later in step S4.(Any of PTN1-4)To set a reach pattern according to the lottery result. Here, as the reach pattern, among the three symbol display units of the variable display device 14, when one symbol is stopped and displayed on each of the two symbol display units, the remaining one symbol display in the reach state where a combination of specific symbols is aligned. There are four types of normal reach E, slow reach F, frame advance reach G, and super slow reach H, as shown in Table 1 below, due to the difference in the fluctuation speed or time of the symbols in the section.
[0019]
[Table 1]
  The four types of reach patterns E to H have their operation information stored as fixed data in the ROM 22 of the control unit 20, and thus the ROM 22 has a function as a game effect pattern storage means according to claim 1.
[0020]
  Subsequently, after the variable display of the symbols is started in the three symbol display units of the variable display device 14 in step S5, reach effect is performed with the reach pattern already set in step S6, and the variation is ended in step S7. That is, among the three symbol display units of the variable display device 14, when the symbols are stopped and displayed on the two symbol display units, a reach state occurs in which a combination of specific symbols is aligned. In this reach state, the set reach Based on the pattern, the fluctuation of the symbol in the remaining one symbol display unit is stopped at a predetermined fluctuation speed or fluctuation time.
[0021]
  Thereafter, it is determined in step S8 whether or not it is a big hit. If this determination is YES, a big hit process is performed in step S9. Jackpot processing is advantageous for playersNaTo create a special gaming state, for example, the special winning opening 16 is opened for a certain period of time so that the pachinko ball can be easily won, and the display lamp group 41 is lit or blinked to notify that the jackpot is being processed. Sound effects are played from the speaker 42.
[0022]
  Then, it shows in following Table 2 by step S10.FourPatterns by reliabilityTable PTN1-4A lottery to choose one from,The random number generator 24 is used, and the lottery result is obtained in step S11.Use the pattern table by reliability as the selection tableSet.
[0023]
[Table 2]
  Here, E to H in the reliability-specific pattern table mean the types of reach patterns in Table 1, for example,Pattern tableFor PTN1, the reach reliability of normal reach E is 0.4%, the reach reliability of slow reach F is 3.6%, the reach reliability of frame advance reach G is 13%, and the reach reliability of super slow reach H Is 33.3%. When the reach reliability is 33.3%, the probability of occurrence of the reach pattern when the jackpot is not a jackpot is 1/200 (when the random number of the jackpot lottery is “0”) and when the jackpot is hit (occurrence probability 1/200). This is a case where the ratio of the reach pattern in 10) is 10/20. When the reach reliability is 13%, the probability of occurrence of the reach pattern when the jackpot is not a jackpot is 2/200 (when the random number of the jackpot lottery is “1,2”) and the ratio of the reach pattern at the jackpot is 6 This is the case of / 20. When the reach reliability is 3.6%, the probability of the reach pattern when the jackpot is not a jackpot is 4/200 (when the random number of the jackpot lottery is “3-6”) and the ratio of the reach pattern at the jackpot Is 3/20. When the reach reliability is 0.4%, the probability of occurrence of the reach pattern when the jackpot is not a jackpot is 13/200 (when the jackpot lottery random number is “8 to 20”) and the ratio of the reach pattern at the jackpot is This is the case of 1/20.
[0024]
  The reliability-specific pattern table stores such numerical information as fixed data in the ROM 22 of the control unit 20, and therefore the ROM 22 is defined in claim 1.tableIt also has a function as a storage means. Also, every time the jackpot processingFourpatternTable PTN1-4Steps S10 and S11 for selecting one from the following are referred to in claim 1.tableIt constitutes the selection change means, the selectionPattern tableSteps S4 to S7 for performing four types of reach effects by using the above-mentioned elements constitute the game effect processing means according to claim 1.
[0025]
  In step S11One reliability pattern tableAfter setting, in step S12 the settingPattern table by reliabilityFor informing the type oftableSwitch the display and return. SettingtableFor informing the type ofTable notificationIsIn Table 2As shown in FIG. 4, after the variable display of the variable display device 14 starts the variable display of the respective symbols, it is displayed visually and implicitly according to the stop order when the change is stopped, for example,Pattern tableIn the case of PTN1, the symbol is first stopped at the left symbol display unit, then the symbol is stopped at the right symbol display unit, and finally the symbol is stopped at the central symbol display unit. Therefore, this step S12 and the variable display device 14 are referred to in claim 1.Selection tableIs configured to provide a notification means for visually or audibly informing the type.
[0026]
  On the other hand, when the determination in step S3 is NO, that is, when there is no reach in the big win lottery, or when the determination in step S8 is NO, that is, when there is no big win, a loss process is performed in step S13, and the process returns. Note that the flowchart shown in FIG. 3 excludes a case where the jackpot is suddenly made without reaching.
[0027]
  Next, the operation and effect of the pachinko machine A according to the first embodiment will be described. When the pachinko ball wins the start winning opening 15, a plurality of symbols are displayed on the three symbol display portions of the variable display device 14, respectively. In addition to being displayed in a variable manner, a jackpot lottery is performed, and if the lottery is a jackpot, after a stop display with a combination of specific symbols, a jackpot process such as opening the special prize opening 16 for a certain period of time is performed. In addition, in order to enhance the fun of the game, even when the lottery is lost, a reach state in which a combination of specific symbols is aligned when the symbols are stopped and displayed on the first symbol display unit and the second symbol display unit is predetermined. From this reach state, reach effects are performed with predetermined reach reliability in four types of reach patterns E to H.
[0028]
  In this case, the correspondence between the four types of reach patterns E to H and their reach reliability is four.Pattern tableDepends on PTN1-4 (see Table 2) and every time jackpot processing is performedPattern tableSince the correspondence between each reach pattern and its reach reliability becomes complicated, the game rut phenomenon caused by the reach production can be suppressed, and the period until the pachinko machine A is discarded is lengthened. be able to. In particular,Pattern tableIn the case of PTN4, the reach reliability of the normal reach E is higher than that of the other reach patterns F to H, which is rich in unexpectedness, and can be interesting.
[0029]
  Moreover,Pattern tableThe types of PTN1 to PTN4 are notified visually and implicitly according to the stop order when the change is stopped after starting the change display of the symbols on the three symbol display parts of the variable display device 14, respectively. Anyone who notices this notificationPattern tableWill be created, or a new interest will be created to guess the correspondence between each reach pattern EH and its reach reliability. It can be further enhanced.
[0030]
  In addition, it does not increase the number of reach patterns in comparison with conventional pachinko machines, it only gives diversity by changing the combination of reach patterns and their reach reliability, and reach reliability The change is only made when the jackpot processing is performed, and the program for the change becomes simple, so the burden on the capacity of the microcomputer is not increased and the implementation is facilitated. be able to.

[0041]
  FIG. 11 is a flowchart showing the control contents of the slot machine B by the machine control unit 150 (specifically, the CPU 151), and the control contents will be described below according to this flowchart.
[0042]
  First, after waiting for the start lever 112 to be operated in step S21, it is determined in step S22 whether or not the bonus winning flag is ON. Since the first bonus winning flag is not set, the determination is NO, the process proceeds to step S23, and a lottery is performed. This lottery is performed using the random number generator 154, and a bonus winning flag is set by winning a bonus such as a big bonus or a regular bonus at a predetermined rate. In addition, a lottery is performed as to whether or not various flag notifications to be described later are made.
[0043]
  Subsequently, in step S24, it is determined whether or not a flag notification is to be made based on the lottery. When this determination is YES, a reliability-specific pattern table selected and set in steps S31 and 32 described later in step S25.(Any of PTN-a to c)To set the type of flag notification according to the lottery result. Here, as the flag notification, the surface emitting LED device 137 in nine blocks each corresponding to the combination of the light emission colors of the backlight light of the rotating reel 131 in the reel device 130, specifically, nine symbols that can be seen through the reel display window 102. There are three types depending on the number of blocks emitted by the green LED 147. That is, K notification of 7 to 9 blocks, L notification of 3 to 6 blocks, and M notification of 0 to 2 blocks. When the green LED 147 does not emit light in the 0 block, the red LED 147 emits light in all blocks. The operation information of these three types of flag notifications is stored as fixed data in the ROM 152 of the machine control unit 150. Therefore, the ROM 152 has a function as a game effect pattern storage means according to claim 1.
[0044]
  Then, after setting the type of flag notification, in step S26, the type of flag notification (light emission color notification) is performed, and the process proceeds to step S27. When flag notification is not performed in step S24, the process immediately proceeds to step S27. In step S27, the reel device 130 is operated to rotate each rotary reel 131. Then, in step S28, each rotary reel 131 is stopped according to the pressing operation of the stop button 113.
[0045]
  Subsequently, it is determined whether or not the three rotary reels 131, 131, 131 stopped in step S29 are big hits with a combination of specific symbols. If the determination is YES, a big hit process is performed in step S30. The jackpot process is, for example, increasing the probability of occurrence of a bonus by generating a special gaming state that is advantageous to the player.
[0046]
  Thereafter, it is shown in Table 3 below in step S31.ThreePattern table by reliabilityPTN-acA lottery to choose one from,The random number generator 154 is used, and the lottery result is determined in step S32.Use the pattern table by reliability as the selection tableSet.

  On the other hand, when the determination in step S29 is NO, that is, when a combination of specific symbols is not prepared on the stopped three reels 131, 131, 131, a losing process is performed in step S34 and the process returns. If the loss process is performed when the bonus winning flag is set, the process proceeds from step S22 to step S25 when the return is made, and the flag notification is performed without performing the lottery. The flowchart shown in FIG. 11 is mainly for flag notification, and the small lottery process and the like are omitted.
[0052]
  Next, the operation and effect of the slot machine B according to the second embodiment will be described. When the start lever 112 is operated, the three rotary reels 131, 131, 131 of the reel device 130 rotate at the same time. When the stop button 113 corresponding to the reel 131 is pressed, each rotating reel 131 is individually stopped, and a combination of specific symbols is placed on the winning lines L1 to L5 of the reel display window 102 activated according to the number of inserted medals. One game win or loss is determined by whether or not they are aligned. This normal game is advantageous for the playerNaA lottery for shifting to the bonus game in the special gaming state is performed (step S23), and if a bonus is won in this lottery, a bonus winning flag is set and the player is informed that this flag is set. Three types of flag notifications (K notification, L notification, M notification) are performed with predetermined notification reliability (step S26).
[0053]
  In this case, the correspondence between the three types of flag notifications and their notification reliability is threePattern Table PTN-acEach time (see Table 3) and every time jackpot processing is performedPattern tableTherefore, it is possible to suppress the phenomenon of game play caused by the notification effect that complicates the correspondence between each flag notification and its notification reliability, and lengthens the period until the slot machine B becomes a disposal table. be able to.
[0054]
  Moreover,Pattern tableThe types of PTN-a to c are notified visually and implicitly when one of the three display lamps 106a to 106c of the big chance game number display unit 106 is lit in green. Any of the noticesPattern tableNew interests will be created to guess whether or not you are playing games or how the correspondence between each flag notification and its notification reliability is, and to further enhance the interest of the announcement production Can do.
[0055]
  In addition, there are only three types of flag notifications. Changing the combination of these three types of flag notifications and their notification reliability can only provide diversity, and changing the notification reliability is a big hit. The change is made only when the process is performed, and the program for the change becomes simple. Therefore, the burden on the capacity of the microcomputer is not increased, and the implementation can be facilitated.
[0056]
  The present invention is not limited to the first and second embodiments described above, but includes other various embodiments. For example, in the first embodiment,Selection tableIn the notifying means for notifying the type of the variable display device 14, a method of notifying by the stop order when the change is stopped after the change display of the symbols on each of the three symbol display parts of the variable display device 14 is started is adopted. In addition, the background color, background pattern, and type of characters appearing on the liquid crystal screen constituting the variable display device 14tableHow to switch separately, decorative pattern and color of the variable patterntableHow to switch separately, background musictableDifferent methods may be used, and not only these implicit notification methods, but also directly on the screen or displaytableOf course, a method of displaying the type of the above may be adopted. Similarly, in the second embodiment, instead of notifying the type of flag notification by lighting the display lamps 106a to 106c of the big chance game number display unit 106 in green, the flag OK notification is made by allowing the stop OK lamp to emit multiple colors. It is also possible to switch the emission color for each type, to change the music at the time of the tempering, to make it easy to understand, or to provide a lamp dedicated to notification type notification.
[0057]
  In the first embodiment, as the reach effect, normal reach, slow reach, frame advance reach and super-reach are changed by changing the fluctuation speed or the fluctuation time from the reach state until the symbol stops at the remaining one symbol display section. Although the case where there are four types of slow reach has been described, as disclosed in, for example, Japanese Patent Laid-Open No. 9-56895, the present invention allows characters to appear on the liquid crystal screen of the variable display device 14 to produce various reach effects. The same can be applied to the case.
[0058]
  Furthermore, in the first and second embodiments, each time the jackpot process is executed once,Pattern tableWas changed, but thisPattern tableIs changed every time a predetermined condition is satisfied, such as when the jackpot process is executed a plurality of times, when the slope of the change in the payout rate of IN / OUT changes, or when the number of fluctuations in the pachinko machine reaches a predetermined number of times. You can do it.
[0059]
【The invention's effect】
  As described above, the present inventionSlot machineAccording to the above, every time a predetermined condition is satisfied, such as when the number of jackpots reaches a predetermined numberFlag announcementSince the correspondence relationship between the game effect patterns and their reliability is changed, it is possible to suppress the game phenomenon and to extend the business period until the game is discarded. In addition, correspondencePredefined reliability pattern tableThe player is notified visually or audibly, so the player canPattern tableIt is possible to create a new interest that guesses whether or not you are playing a game, and it is also possible to improve the ability to attract customers. In addition, the number of game production patterns is not increased, and the program for changing the reliability is simplified, so that the burden on the capacity of the microcomputer is not increased and implementation is attempted. It is very effective.
[0060]
  In particular, the claims2In the invention according toSelection table for different patternsIs differentThose flag announcementsSince the magnitude relationship of reliability is reversed, it is possible to further enhance the interest of the game by exhibiting unexpectedness.
