Description

  The present invention relates to a gaming machine, and more particularly, to a gaming machine having a plurality of probabilities of generating a gaming state advantageous to a player.

  2. Description of the Related Art Conventionally, a gaming machine that provides a state of “high probability state” having a higher probability of winning a jackpot than usual and varies the probability is provided. The transition to the high probability state is generally performed when the jackpot game is finished. Therefore, by shortening the opening time of the jackpot in the jackpot game and reducing the number of times of opening, the jackpot game is extremely shortened, and it is given after the jackpot game ends without appealing to the player that the jackpot game has been provided. There is also a gaming machine in which the effect of “suddenly probable” is performed, in which only the state change (probability variation) “transition to a high probability state” appears as a privilege to the player (see, for example, Patent Document 1). This “sudden probability change” effect makes the player feel as if he / she has transitioned to a high-probability state even though no jackpot game has been played.

In addition, some conventional gaming machines notify a high probability state, but a gaming machine that does not notify a high probability state (so-called probability variation concealment) is also provided.
JP 2005-160740 A

  However, in a game machine that suddenly changes the probability, a player who is familiar with the game knows that when the sudden probability change is performed, a jackpot game is performed in which the winning prize opening is extremely short. In addition, there is a problem that it is possible to suddenly determine the probability change by paying attention to the open state of the special winning opening before it is notified that the transition to the high probability state has been performed. Therefore, since the player knows the result before the original notification, the player cannot enjoy the original notification, and loses interest in the game.

In addition, it is difficult to win a big prize opening despite the fact that a jackpot game is being played, so the player perceives the jackpot as a low-value jackpot, and detracts from the player's willingness to play. There is a problem that it may be. Further, unexpectedly probability variation at atmospheric per Limi row, as the transition to a high probability state is performed, the jackpot game would end with a very short time. Therefore, it is possible to acquire enough game balls, and it can be perceived as a jackpot with a low value compared to the normal probability fluctuation jackpot where the transition to a high probability state is also performed, and the player's willingness to play can be aroused There is a problem that there is.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a gaming machine in which the player does not detect the type of privilege.

In order to solve the above problems, in the gaming machine according to the first aspect of the present invention, a game ball detecting means for detecting a winning of a game ball in a specific winning opening provided on the game board, and the game ball detecting means Random number obtaining means for obtaining a random value due to detection of a game ball, jackpot determining means for judging whether or not the jackpot is based on the random value obtained by the random number obtaining means, and the jackpot A low probability state in which the probability of being determined to be a big hit by the determination means is a normal probability, and a high probability state in which the probability of being determined to be a big hit is higher than the normal probability. A probability change control means for changing the probability determined to be a jackpot by the jackpot, and when the jackpot determination means determines the jackpot, the probability change control means determines the high probability state. Wherein the probability change jackpot determining means for determining whether the probability change jackpot is jackpot, if it is determined that the jackpot by the jackpot determining means, a predetermined winning hole provided in the game platen to The jackpot game control means for executing any of a plurality of jackpot games for allowing the game ball to win, and whether the winning is different from the jackpot based on the random value acquired by the random number acquisition means. and hit judging means in determining whether, when it is determined that hit in the by the in hit determination means, one or more per among which the game balls to the predetermined winning opening is a winning ready a per game control unit in carrying out any of the game, the predetermined by the in per game control means in at least one of the game per in the The number of times the game balls to a prize port are possible winning state, the jackpot when at least a portion of the bonus game when it is determined that the probability change jackpot by the probability change jackpot determining means of the jackpot gaming Game control means for setting the same number of times that the game ball can be awarded to the predetermined winning opening by the game control means, and a determination result provided by the jackpot determination means provided on the game board, and Determined by a special symbol display means for displaying a special symbol which is a symbol indicating a determination result by the middle hit determination means, a special symbol determination means for determining the special symbol to be displayed on the special symbol display means, and the special symbol determination means A variation for storing a plurality of variation patterns for designating a rendering method and a rendering time when displaying the special symbol displayed on the special symbol display means A variation pattern selecting unit that selects the variation pattern to be used from the variation patterns stored in the variation pattern storage unit; and the variation pattern selection unit that selects the special symbol determined by the special symbol determination unit.

In the jackpot game and the mid-win game in which the number of times played is the same, the number of times that the game ball can be won in the predetermined winning opening is at least one, and the predetermined number The time during which the game ball can be won in the winning opening is shorter than the time interval between the game balls when the game balls are continuously fired.

In the gaming machine according to the first aspect of the present invention, a plurality of jackpot games are provided, one or more hit games are provided, and the game control means is configured to play a hit in at least one of the hit games. The number of times that a game ball can be awarded in a predetermined winning opening by the game control means, and a state in which game balls can be awarded in a predetermined winning opening by the big hit game control means in at least one of the big win games The same number of times can be set. Therefore, it is not possible to distinguish whether a win game is being played or a jackpot game is being played simply by looking at the state of a predetermined winning opening. The probability change control means includes a low probability state in which the probability of being determined to be a big hit by the jackpot determining means is a normal probability, and a high probability state in which the probability of being determined to be a big hit is higher than the normal probability. The probability that the jackpot is determined to be a jackpot is changed, and the probability variation jackpot determination means is a jackpot change that is a jackpot that is set to a high probability state by the probability change control means when the jackpot determination means is determined to be a jackpot In the jackpot game executed by the jackpot game control means in at least a part of the case where the probability change jackpot is determined by the probability variation jackpot determination means, the game control means At least one of the games, the same number of times as the number of times that the game ball can be won in a predetermined winning opening Game ball the winning hole can be made possible winning state of. Therefore, it is not possible to distinguish whether a jackpot game based on a jackpot that is set to a high probability state is being played or whether a middle hit game is being played. The special symbol display means provided on the game board displays a special symbol which is a symbol indicating the determination result by the jackpot determination means and the determination result by the middle hit determination means, and the special symbol determination means displays on the special symbol display means. The variation pattern storage means stores a plurality of variation patterns that specify a rendering method and a rendering time when the special symbol determined by the special symbol determination means is displayed on the special symbol display means. The pattern selection means selects a fluctuation pattern to be used from the fluctuation patterns stored in the fluctuation pattern storage means, and the special symbol display control means determines the special symbol determined by the special symbol determination means by the fluctuation pattern selection means. According to the variation pattern, the special symbol can be displayed in a fixed manner after the special symbol is variably displayed on the special symbol display means. In addition, in the big hit game and the big hit game in which the number of times that the game ball can be won in the predetermined winning opening by the game control means is the same number, the big hit game in which the big hit game is performed is selected by the variation pattern selection means A part of the specific probability variation pattern that is the variation pattern to be matched with the middle hit variation pattern that is the variation pattern selected by the variation pattern selection means in the middle hit in which the middle hit game is performed, and the specific probability variation pattern Since some of them are different from the mid-bonus variation pattern, the same variation pattern exists between the variation pattern when the jackpot is notified and the variation pattern when the mid-bonus is notified. While the hit judgment result is being notified, it is possible to distinguish whether it is a big hit or a middle hit. There.

Moreover, in the gaming machine of the invention according to claim 2 , in addition to the effect of the invention according to claim 1 , since the number of special symbols displayed on the special symbol display means is more than 10, a special symbol is displayed. During the notification, it is difficult to determine whether it is a big hit, a middle hit or a miss.

In addition, in the gaming machine of the invention according to claim 3 , in addition to the effect of the invention according to claim 1 or 2 , the directing means displays or determines the special symbol on the special symbol display means by the special symbol display control means. While being displayed, the effect member performs various effects, the effect pattern storage means stores an effect pattern that is an effect method by the effect means, and the effect pattern selection means is stored in the effect pattern storage means.

  Further, warp inlets 22 and 23 are respectively provided on the left and right shoulders of the symbol display device 8. Furthermore, a warp outlet 21 (see FIG. 3) is provided at the lower part of the symbol display device 8, and the game balls that have passed through these warp inlets 22, 23 pass through the interior (warp zone) of the symbol display device 8 to obtain a warp outlet. Appears to 21. The game ball that has appeared at the warp outlet 21 falls toward the special symbol starter electric accessory 15 provided immediately below the warp outlet 21, so that it is easy to win the special symbol starter electric accessory 15.

  Moreover, as shown in FIG. 3, the normal symbol display part 24 comprised from 7 segment LED is provided in the upper part of the symbol display apparatus 8. FIG. The normal symbol display unit 24 can display symbols such as single-digit numbers and single-letter alphabets. Further, a special symbol memory number display LED 60 composed of four LEDs is provided at the upper part of the symbol display screen 28 of the symbol display device 8. In this special symbol memory number display LED 60, the number of game balls that have won the special symbol start electric accessory 15 (see FIG. 2) and whose jackpot determination result is not yet displayed on the symbol display screen 28, so-called special symbol operation. Up to four reserved balls can be displayed by lighting the LEDs. Further, a normal symbol memory number display LED 59 comprising four LEDs provided below the normal symbol display unit 24 wins the normal symbol start gate 12 (see FIG. 2), and the normal symbol display unit 24 receives a normal hit. The number of game balls for which the determination result is not yet displayed, that is, the so-called number of normal symbol actuated balls, can be displayed by turning on the LED, up to four as with the special symbol actuated ball. In addition to the above, the game board 2 (see FIG. 2) includes various electric lamps 63 (see FIG. 4), other LED 62 for electric decoration (see FIG. 4), a windmill, and many obstacle nails. Is provided.

  As shown in FIG. 2, special symbol display portions M <b> 1 and M <b> 2 are arranged side by side at the lower right of the symbol display device 8. The special symbol display portions M1 and M2 are each composed of 7-segment LEDs, and can display symbols such as single-digit numbers and single-letter alphabets. In the present embodiment, two-digit symbols can be displayed on the special symbol display portions M1 and M2, and 26 types of alphabet combinations from “A” to “Z” are displayed. The special symbol display portions M1 and M2 determine the jackpot when a game ball wins the special symbol starting electric player 15, 26 types of characters are sequentially displayed (variable display), and a predetermined variable display time. After a lapse, the fluctuation stops and the special symbol indicating the jackpot result stops (confirmed display). Note that the fluctuation display time is not constant, and is determined for each fluctuation pattern described later.

  Next, the screen displayed on the symbol display screen 28 will be described. As shown in FIG. 3, on the symbol display screen 28, three demo symbol display portions are arranged in a horizontal row in the order of the demo symbol display portion L1, the demo symbol display portion L3, and the demo symbol display portion L2 from the left. Yes. In the demo symbol display portions L1 to L3, a demo symbol, which will be described later, is variably displayed so as to scroll from top to bottom, and the demo symbol display portion L1, the demo symbol display portion L2, and the demo symbol display portion L3 are stopped in this order. It has become. The arrangement of the demonstration symbol display portions L1 to L3, the stop display order, the scroll direction, etc. can be arbitrarily changed.

  On the symbol display screen 28, images, messages, and the like are also displayed in the background of the demo symbol display portions L1 to L3. Further, the demo symbols are not always displayed on the demo symbol display portions L1 to L3, and an image, a message, or the like can be displayed instead of these displays. The symbol display device 8 includes a symbol display substrate 44 (see FIG. 4) on the back surface thereof.

  In this embodiment, the numbers “0”, “1”, “2”, “3”, “4”, “5”, “6”, “7” are displayed on the demo symbol display portions L1 to L3. ”,“ 8 ”and“ 9 ”are displayed. The demo symbol display portions L1 to L3 start to change in synchronization with the start of change of the special symbol display portions M1 and M2, and 10 kinds of symbols are sequentially displayed in this order in principle. Then, the symbols stop in the order of the demo symbol display portions L1, L2, and L3 in accordance with the operation in which the special symbol display portions M1 and M2 stop after a predetermined fluctuation display time has elapsed, and finally the three demo symbols are displayed. All the fluctuations of the display parts L1 to L3 are stopped, and the demo symbol indicating the jackpot result is stopped (determined display).

  In the case of “hit”, a “hit game state” is generated in which the big prize opening 16 is opened a predetermined number of times and for a predetermined time. In the present embodiment, the jackpot game is provided with a jackpot of 15 times and a jackpot of 2 times in the jackpot game. When the special winning opening 16 is opened, a predetermined number (for example, 10 balls) of game balls enter or close when a predetermined time has elapsed. Here, in the present embodiment, the predetermined time is 10 seconds when opening 15 times, and 0.3 seconds when opening twice, and when opening twice, the predetermined time is opened. Unless it is the timing at which the game ball is about to pass over the big winning opening 16, the game ball cannot be won and the player cannot catch the game ball.

  Further, in the present embodiment, a “high probability state” is provided, which is a state in which the probability of becoming a “big hit” in the big hit determination is high. In the “bonanza”, there are two types of jackpots: a jackpot that is in a high probability state after the jackpot game ends and a jackpot that is not in a high probability state. Furthermore, in the pachinko machine 1 according to the present embodiment, a hit called “medium hit” is provided in addition to “big hit”. This mid-winning determination is performed when the jackpot determination is “out of place”, and when it is “mid-winning”, the big winning opening 16 is opened twice for 0.3 seconds. A "winning game state" is created.

  Here, when combining the types of jackpots between the number of opening of the big prize opening and the probability state, the jackpot that becomes the high probability state of 15 times opening (per 15R probability fluctuation), the jackpot that does not become the high probability state of 15 times opening There are four types of big hits (per 15R non-stochastic fluctuations), big hits (per 2R random fluctuations) that become a two-probability high probability state (per 2R non-stochastic fluctuations) In this embodiment, “per 2R non-probability fluctuation” is not set. In “per 2R probability fluctuation”, the grand prize winning opening 16 is opened only for 0.3 seconds twice, so that it is unlikely that a game ball can be obtained. However, there is a privilege of “high probability state”. Furthermore, it is almost impossible to win the grand prize winning opening 16 of “medium hit”, and there is a lower value win that does not shift to the high probability state. Since it is more valuable than "medium hit", it does not distract the player's desire to play.

In other words, when the game ball wins the special symbol starting electric accessory 15, the results of “per 15R probability change”, “per 15R non-probability change”, “per 2R probability change”, “medium hit”, and “out of” are given. It is done. These results are displayed on the special symbol display portions M1 and M2 and the demo symbol display portions L1 to L3. Here, the symbols displayed on the special symbol display portions M1 and M2 and the demo symbol display portions L1 to L3 will be described. Table 1 is a correspondence table between the determination results for each item and the symbols displayed on each symbol display unit.

  In the case of “15R probability variation jackpot”, the special symbol display portions M1 and M2 display a combination of alphabets designated as “special symbols per 15R probability variation”, and the demo symbol display portions L1 to L3 include All the same odd numbers are displayed. That is, “1,1,1”, “3,3,3”, “5,5,5”, “7,7,7”, “9,9,9”. The combination will be referred to as an “odd roll”. In the present embodiment, 130 of the two-digit alphabet combinations are designated as “special symbols per 15R probability change”.

  Further, in the case of “15R non-probability variation jackpot”, the special symbol display portions M1 and M2 display a combination of alphabets designated as “special symbols per 15R non-probability variation”, and the demo symbol display portions L1 to L1. L3 displays the same even number. That is, “0, 0, 0”, “2, 2, 2”, “4, 4, 4”, “6, 6, 6”, “8, 8, 8”. The combination is referred to as “even numbered eyes”. In the present embodiment, among the combinations of two-digit alphabets, 130 symbols that are not “special symbols per 15R probability variation” are designated as “special symbols per 15R non-probability variation”.

  Further, in the case of “2R probability variation jackpot”, the special symbol display portions M1 and M2 display the alphabet combination “2R probability variation jackpot”, and the demo symbol display portions L1 to L3 include Values that increase by 1 in the order of L1, L3, and L2 are displayed. For example, “1, 2, 3”, “2, 3, 4”, and the like. Hereinafter, such a combination of symbols is referred to as “order”. In the present embodiment, among the combinations of two-digit alphabets, 130 symbols that are not “special symbols per 15R probability variation” and “special symbols per 15R non-probability variation” are designated as “2R probability variation jackpot special symbols”.

  In the case of “medium hit”, the special symbol display portions M1 and M2 display a combination of alphabets designated as “medium hit”, and the demo symbol display portions L1 to L3 indicate “2R probability variation”. The same order as “winning” is displayed. Further, in the present embodiment, among the combinations of two-digit alphabets, 130 “special symbols per 15R probability variation”, “special symbols per 15R non-probability variation” and “special symbols per 2R probability variation jackpot” are selected as “medium” It will be a special symbol.

In the case of “missing”, the special symbol display portions M1 and M2 display a combination of the alphabets designated as “missing”, and the demonstration symbol display portions L1 to L3 display a random pattern. Not a combination is displayed. In the present embodiment, among the combinations of two-digit alphabets, “special symbol per 15R probability variation”, “special symbol per 15R non-probability variation”, “special symbol per 2R probability variation jackpot” and “special symbol per medium” The remaining 146 are not.

  In the gaming machine of the present invention, not only “big hit” but also “medium hit” is provided. In the “2R probability variation jackpot” and “medium bonus”, in the jackpot game or the jackpot game, the big prize opening 16 is opened twice for 0.3 seconds. In addition, the symbols displayed on the demo symbol display portions L1 to L3 are both in order. Therefore, even if the special winning opening 16 is opened very short twice, the player cannot distinguish whether it is “2R probability variation jackpot” or “medium hit”. In other words, even if the special winning opening 16 is opened very short twice, it is not possible for the player to determine whether or not to shift to a high probability state (so-called sudden probability change).

  Next, the storage area of the RAM 52 will be described with reference to FIG. FIG. 6 is a conceptual diagram showing a storage area of the RAM 52. As shown in FIG. 6, the RAM 52 has a counter storage area 5201 for storing various counters, a winning ball flag storage area 5202 for storing a flag indicating whether or not a game ball has been won at each gate or each winning opening, Normal hit relation information storage area 5203 for storing a random number acquired when winning a game ball to the normal symbol start gate 12, normal symbol operation reserved ball number storage area 5204 for storing the number of normal symbol start operation hold balls, special symbol start Sub-integration from the main board 41, a jackpot related information storage area 5205 for storing random numbers acquired when winning a game ball to the electric accessory 15, a special symbol operation reserved ball number storage area 5206 for storing the number of special symbol operation reserved balls A command-related storage area 5207 for storing control commands output to the board 58, which indicates whether or not it is a big hit gaming state A flag relation storage area 5208 for storing flags such as a game state flag, a display state flag indicating the state of the special symbol display portions M1 and M2, a probability variation flag indicating whether or not to set a high probability state, and the like are provided. . Note that a backup battery (not shown) is connected to the RAM 52 so that stored contents are retained even when the pachinko machine 1 is powered off. Further, the RAM 52 is provided with various storage areas not shown.

  Next, the counter storage area 5201 will be described. The counter storage area 5201 includes a normal hit determination counter, a jackpot determination counter, a probability change determination counter, a round number determination counter, a special symbol determination counter, a variation pattern determination counter, a special symbol variation time counter, a special symbol stop time counter, etc. It is remembered. These values are fetched and stored in the normal hit relation information storage area 5203, the big hit relation information storage area 5205, etc. in the normal symbol processing and special symbol processing described later, or used as a timer counter.

  The values of the normal hit determination counter, the big hit determination counter, the special symbol determination counter, and the fluctuation pattern determination counter are the values of the pachinko machine 1 that are executed based on the interrupt signal from the interrupt signal generation circuit 57 (see FIG. 4). In the counter update process (see FIG. 8) of the main process of the control program, a predetermined amount (for example, “1”) is added at regular time intervals (for example, 2 ms, which is an interrupt signal generation interval). Each counter is provided with a minimum value (lower limit value) and a maximum value (upper limit value), and is configured to circulate within a numerical value in the range from the minimum value to the maximum value. In other words, if the counter value becomes the same as the maximum value as a result of the update, the counter value takes the minimum value in the next update. The special symbol variation time counter and the special symbol stop time counter are used as timer counters for measuring the elapsed time, and are decremented by a predetermined amount (for example, “1”) in the counter update process (see FIG. 8). The

  Hereinafter, each counter will be described in detail. The value of the normal hit determination counter is used for determining the normal hit. The normal hit determination is performed in response to a winning of a game ball to the normal symbol start gate 12. When it is determined that the hit is normal, the opening / closing member of the special symbol starting electric accessory 15 is opened for a predetermined time (for example, 0.5 seconds). The maximum value of the normal hit determination counter is “255”, and the minimum value is “0”.

  The value of the jackpot determination counter is used to determine the jackpot and middle hit. The maximum value of the jackpot determination counter is “314” and the minimum value is “0”. When “1” is added every interrupt (every 2 ms) and becomes “315” or more, the value returns to “0”. Therefore, the value of the jackpot determination counter takes any value from “0” to “314”, and one period is 630 ms. In addition, when the pachinko machine 1 is activated, the jackpot determination counter stores “0” as an initial value. When the value is rounded to the same value as the initial value “0” by updating, a new initial value is set. Acquired, and “1” is added to the initial value. This new initial value is repeatedly executed while the CPU 51 does not perform the main process (see FIG. 8) (until the main process ends and a new main process is started by an interrupt signal). A random number generated by an initial value random number process (a process for generating a random number by a predetermined algorithm) not shown is used. For example, when the random number generated by the initial value random number processing is “18”, “19” and “20” are added by the update, and when “314” is obtained, the processing returns to “0” and “1”. ”And“ 2 ”are added, and when“ 18 ”is obtained, a new initial value is acquired. The maximum value of the jackpot determination counter may be a single set value, or setting means for selecting and setting different values such as setting 1, setting 2, and setting 3 may be provided.

  The value of the determination counter per probability change is used to determine whether the value is per probability change or a non-probability change when it is a big hit. The round number determination counter is used to determine whether the number of rounds is 2 rounds or 15 rounds per probability variation. The value of the special symbol determination counter is used to determine the symbol displayed in the special symbol, and the maximum value is “9489” and the minimum value is “0”.

  The value of the variation pattern determination counter is used to determine the variation pattern. The variation pattern is a type of effect when notifying the result of the jackpot determination, and is selected according to the value of the variation pattern determination counter or the result of the jackpot determination. The selected variation pattern is transmitted to the sub-integrated substrate 58 as a variation pattern designation command, and further transmitted from the sub-integrated substrate 58 to the sound substrate 43, the symbol display substrate 44, and the electrical decoration substrate 46. Note that the time from the start of change to the stop of all symbols in the special symbol display portions M1 and M2 is determined for each change pattern, and the deviation change pattern storage area 5305, the hit change pattern storage area 5306, the sudden probability change pattern of the ROM 53 It is stored in the storage area 5307. In the present embodiment, 62 types of variation patterns are provided. The maximum value of the variation pattern determination counter is “65535”, the minimum value is “0”, and “1” is added every interrupt (every 2 ms) and becomes “0” when the value is larger than “65535”. Return to. There are three variation pattern determination tables (not shown) for the case of a big hit, when the variation is shortened (the variation time of the special symbol is shortened), and when the variation is not shortened. Each of 62 types of variation patterns is assigned to the values “0” to “65535”.

  The special symbol variation time counter is a timer counter that is used to measure the time (variation time) from when the special symbol display units M1 and M2 start to vary until all symbols stop. The variation time is stored as an initial value, and “1” is subtracted every interrupt (2 ms) in the counter update process, and when the value becomes “0”, the timing for terminating the variation is determined. For example, when the variation time is 10 seconds, “5000” is stored as the initial value. The variation time is determined for each variation pattern.

  The special symbol stop time counter is a timer counter that is used to measure the time (stop display time) during which symbols are stopped and displayed on the special symbol display portions M1 and M2. The stop time is stored as an initial value, and “1” is subtracted every interrupt (2 ms) in the counter update process, and when the value becomes “0”, the timing for stopping the stop display is determined. For example, when the stop display time is 5 seconds, “2500” is stored as the initial value.

  Next, the jackpot relation information storage area 5205 will be described with reference to FIG. FIG. 7 is a conceptual diagram showing a jackpot relation information storage area 5205 of the RAM 52.

  Next, the jackpot relation information storage area 5205 will be described. As shown in FIG. 7, the jackpot relation information storage area 5205 is provided with a determination area and first to fourth storage areas. The jackpot relation information storage area 5205 is used in a special symbol process (see S14 in FIG. 8) of the main process described later. In the first memory area to the fourth memory area, a random number obtained by a game ball (special symbol operation holding ball) for which a game ball has won a prize for the special symbol starting electric accessory 15 and the jackpot determination result has not been notified yet. Is memorized. In the determination area, the result of the jackpot determination that is currently being performed and a random number based on the jackpot game are stored.

  In the special symbol process, when the winning of the game ball to the special symbol starting electric accessory 15 is confirmed, the value of the special symbol operation reserved ball number storage area 5206 in the first memory area to the fourth memory area ( Each value is stored in a storage area of a number corresponding to the number of special symbol actuated balls. For example, if the number of special symbol operation reservation balls is “3”, it is stored in the third storage area. And if the process with respect to the winning ball memorize | stored in the determination area is complete | finished, the process of the following special symbol operation reservation ball | bowl will be performed. Therefore, the value stored in the first storage area is shifted to the determination area, and the jackpot determination result is notified based on the value stored in the determination area. Further, as the first storage area is shifted to the determination area, the value of the second storage area is changed to the first storage area, the value of the third storage area is changed to the second storage area, and the value of the fourth storage area is changed. Shifting sequentially to the third storage area, the value of the fourth storage area is cleared. Here, the number of storage areas is four. In other words, the number of game balls that have won the special symbol starting electric accessory 15 can store a random number and can hold the operation is four. Therefore, the upper limit of the number of special symbol operation reserved balls is four, and the value of the special symbol operation reserved balls number storage area 5206 does not take a value larger than “4”.

  Each of the determination area and the first storage area to the fourth storage area includes a jackpot random number field probability variation random number field, a round number random number field, a special symbol random number field, and a variation pattern random number field. Each value of a variable random number, a round number random number, a special symbol random number, and a variable pattern random number is stored. Specifically, the value of the jackpot determination counter is in the jackpot random number column, the value of the probability variation determination counter is in the probability variation random number column, the value of the round number counter is in the round number random number column, and the value in the special symbol random number column is The value of the special symbol determination counter is stored, and the value of the variation pattern determination counter is stored in the variation pattern random number column.

  Next, details of the operation of the pachinko machine 1 according to the present embodiment will be described with reference to the flowcharts shown in FIGS. FIG. 8 is a flowchart of the main process. 9 and 10 are flowcharts of the special symbol process performed in the main process. FIG. 11 is a flowchart of the special electric accessory process performed in the main process. Hereinafter, each step of the flowchart is abbreviated as “S”.

  The control of the pachinko machine 1 is performed by a control program stored in a control program storage area 5302 (see FIG. 4) of the ROM 53. The main process of the control program is executed by the CPU 51 when the CPU 51 senses an interrupt signal generated by the interrupt signal generation circuit 57 (see FIG. 4). Since the interrupt signal is generated at regular intervals (2 ms in the present embodiment), the main process is repeatedly executed every 2 ms. When the power of the pachinko machine 1 is turned off, the checksum of the RAM 52 is calculated and a password is generated using, for example, a hash function. When the power is turned on next time, the same process is performed to check the identity of the checksum of the RAM 52 and the generated password. When the identity with the last power-off is not recognized, the CPU 51 of the pachinko machine 1 uses the value stored in the initial setting storage area 5301 of the ROM 53, for example, clears the value of each counter and each flag. For example, the pachinko machine 1 is reset. The pachinko machine 1 is also reset when the power of the pachinko machine 1 is turned on while pressing a reset button (not shown). When the pachinko machine 1 is not reset, so-called return processing is performed in which the state of each storage area of the RAM 52 is returned to the same state as when the power was previously turned off.

  As shown in FIG. 8, when the main process is started by sensing an interrupt signal, a command output process is first performed (S10). In this command output process, a control command is output to the sub integrated board 58 via the I / O interface 54. Control commands include, for example, a special symbol operation hold command indicating the number of special symbol operation hold balls, a normal symbol operation hold command indicating the number of normal symbol operation hold balls, and a variation pattern designation command used when notifying the jackpot determination result , Special symbol designation command, all symbol stop command, normal symbol designation command used to notify the judgment result of normal hit, normal symbol stop command, jackpot start screen display command used in jackpot gaming state, large These are a prize opening opening command, a big winning opening closing command, a jackpot end screen display command, and the like. The control command output here is a control command stored as an output command in the command relation storage area 5207 in the main process executed last time.

  Next, a switch reading process is performed (S11). This switch reading process detects the winning of the game ball to the normal symbol starting gate 12, the special symbol starting electric accessory 15, the big winning port 16, the normal winning ports 17, 18, 19, 20 and the like. Specifically, a start port switch 72 provided in the special symbol start electric accessory 15, a normal symbol operation switch 73 provided in the normal symbol start gate 12, and a count switch 75 provided in the special winning opening 16. A winning port switch 76 for detecting the winning of the game ball to the winning ports such as the normal winning ports 17, 18, 19, 20 is used. If it is determined that a winning is made, “1” is stored in the flag corresponding to each switch stored in the winning ball flag storage area 5202 of the RAM 52 and turned ON.

  Note that the main process performing the switch read process is executed at intervals of the CPU 51 receiving the interrupt signal, that is, every 2 ms. Therefore, considering the speed at which the game ball passes through the switch and the size of the game ball, the switch reading process is performed a plurality of times while one game ball passes through the switch. Therefore, winning of one game ball is detected by a plurality of continuous switch reading processes. Therefore, for example, it is determined that the game ball has won a prize only when the state of “non-detection”, “detection”, and “detection” is reached in three consecutive executions of the switch reading process. At the start of the switch reading process, all the flags in the winning ball flag storage area 5202 are reset.

  When the switch reading process ends, a counter update process is then performed (S12). In this counter update process, each value of the normal hit determination counter, the big hit determination counter, the special symbol determination counter, and the variation pattern determination counter stored in the counter storage area 5201 of the RAM 52 is added by the predetermined amount, and the special symbol is added. Each value of the fluctuation time counter and the special symbol stop time counter is subtracted by the predetermined amount. When the values of the normal hit determination counter, the big hit determination counter, the special symbol determination counter, and the fluctuation pattern determination counter exceed the maximum values of the counters, the values of the counters are programmed to return to the minimum values. In addition, when each value of the special symbol variation time counter and the special symbol stop time counter becomes “0”, it is programmed not to perform further subtraction.

  When the counter update process ends, a special electric accessory process is performed (S13). In this special electric accessory processing, the operation of the big hit gaming state for opening and closing the special winning opening 16 is controlled. This special electric accessory processing will be described later with reference to the flowchart shown in FIG.

  When the special electric accessory process is completed, a special symbol process (S14) is performed. In this special symbol processing, determination of jackpot, determination of symbols and variation patterns displayed on the special symbol display units M1 and M2, instructions, instructions for starting and ending symbol variation, and the like are performed. This special symbol process will be described later with reference to the flowcharts shown in FIGS.

  When the special symbol process is completed, a normal electric accessory process is then performed (S15). In this normal electric game processing, the special symbol starting electric game is made so that the game ball can easily win the special symbol starting electric game 15 after the result is displayed on the normal symbol display unit 24. Control of opening and closing (normally hitting operation) of a pair of opening and closing members (so-called tulips) provided in 15 is performed. Note that the normal winning determination and the display of symbols on the normal symbol display unit 24 are performed in the normal symbol processing of the next S16.

  In the next normal symbol process (S16), acquisition of a random number per normal symbol, determination per normal symbol, an instruction to notify the normal symbol display unit 24 of the determination result per normal symbol, and the like are performed. When the flag corresponding to the normal symbol operation switch 73 in the winning ball flag storage area 5202 is set in the switch reading process of S11, the value of the normal hit determination counter is acquired. Then, “1” is added to the number of normal symbol operation reservation balls in the normal symbol operation reservation ball number storage area 5204. The number corresponding to the value stored in the normal symbol actuated holding ball number storage area 5204 in the first to fourth storage areas of the normal hit relation information storage area 5203 is the value of the normal hit determination counter. Are normally stored as random numbers in the storage area. Then, the value of the first storage area is shifted to the determination area, the normal hit determination is performed based on the normal random number stored in the determination area, and the determination result is notified. As the value of the first storage area is shifted to the determination area, the values of the second storage area, the third storage area, and the fourth storage area are also changed to the first storage area, the second storage area, and the third storage area, respectively. Shifted to.

  Since the value of the normal hit determination counter that is the basis of the value of the normal hit random number takes a value from “0” to “255”, the normal hit random number also takes a value from “0” to “255”. Therefore, in this embodiment, when the normal random number is “64” to “255”, it is normal hit, and when it is “0” to “63”, it is out of range. Control commands such as a normal symbol designation command and a normal symbol stop command are transmitted to the sub-integrated board 58 in order to instruct the normal symbol display unit 24 to notify the result of the determination. In the case of normal winning, “7” is displayed as the winning symbol on the normal symbol display unit 24, and in the case of losing, “−” is displayed as the missing symbol. After the winning symbol is displayed on the normal symbol display unit 24, the opening / closing member of the special symbol starting electric accessory 15 is opened and closed in the above-described normal electric accessory processing (S15).

  When the normal symbol process is completed, a payout control for paying out the prize balls is performed (S17), and then an error check is performed (S18). If an error has occurred in the pachinko machine 1, the symbol display device 8 displays an error, the LED 62 or the illumination lamp 63 is lit or blinked, or an error sound is generated from the speaker 48. Therefore, an error command for transmission to the sub-integrated board 58 in the command output process of S10 is stored in the command relation storage area 5207. Next, an information output process is performed (S19). In this information output process, various types of information such as jackpot information, starting information, probability variation information, variation shortening information, etc., of the pachinko machine 1 are output to an unillustrated game hall management computer via the output port 55. When the information output process ends, the main process ends. When the interrupt signal is received from the interrupt signal generation circuit 57, the main process is executed again from the beginning.

  Here, a series of flows of the main process will be described by taking as an example the operation of the pachinko machine 1 when a certain game ball wins the special symbol starting electric accessory 15 and is determined to be a big hit. When the player operates a launch handle 7 provided on the lower side of the game board 2 to launch a game ball into the game area 4, the game ball flows down the game area 4. When the game ball wins the special symbol starting electric combination 15, winning of the game ball to the special symbol starting electric combination 15 is detected in the switch reading process, and the corresponding flag in the winning ball flag storage area 5202 is turned ON. (S11). Then, in the special symbol processing (S14), the jackpot determination is performed, and the variation of the symbols of the special symbol display portions M1 and M2 is started. While the main process is repeatedly performed, the changing special symbol display portions M1 and M2 are stopped, and the special symbols are stopped and displayed. When the special symbol stop display ends, the jackpot gaming state flag in the flag-related storage area 5208 is turned ON (S14). 16 is released, and the operation in the jackpot gaming state is started. Then, while the main process is repeatedly performed, the operation in the big hit gaming state is performed according to the predetermined condition in the special electric accessory process (S13). When the jackpot gaming state ends, “0” is stored in the jackpot gaming state flag and is turned OFF, and a series of operations relating to this gaming ball is terminated.

  Next, details of the special symbol process (S14) of the main process will be described with reference to the flowcharts shown in FIGS. As described above, in the special symbol processing, jackpot determination, determination of special symbols to be displayed on the special symbol display portions M1 and M2 of the symbol display screen 28, determination of variation patterns, command output to the sub-integrated board 58, etc. Done.

  First, the flags used in the special symbol process will be described. The flag relation storage area 5208 stores a display state flag, a jackpot gaming state flag, a probability state flag, and the like. The display state flag is “1” when the special symbol display portions M1 and M2 are changing (during change), and “1” when the special symbol display portions M1 and M2 are stopped (when stopped). “2”, “0” is stored when the state is neither variable nor stopped. The jackpot gaming state flag is “1” stored and turned ON when the jackpot gaming state is set, and “0” is stored and turned OFF otherwise. The probability state flag is “1” stored in the high probability state and turned on, and “0” is stored and turned off in the low probability state.

  As shown in FIG. 9, when the special symbol process of the main process is started, it is determined whether or not a game ball has won the special symbol start electric accessory 15 (S21). In the main process switch reading process (FIG. 8: S11), when the start opening switch 72 provided in the special symbol start electric accessory 15 detects the winning of the game ball, the start of the winning ball flag storage area 5202 is started. The flag corresponding to the mouth switch 72 is ON. Therefore, in S21, it is determined whether or not the flag corresponding to the start port switch 72 is ON. If it is not ON (S21: NO), the game ball wins the special symbol start electric accessory 15. Since it is not, proceed to S25 as it is.

  When the flag corresponding to the start port switch 72 is ON (S21: YES), since a game ball is won in the special symbol start electric accessory 15, a random number for the game ball is acquired, and the jackpot relation It is stored in the information storage area 5205. However, the number of special symbol actuating balls that can acquire and store random numbers is four. Therefore, it is determined whether or not the value of the special symbol operation reserved ball number storage area 5206 is “4” (S22). If the value of the special symbol operation reserved ball number storage area 5206 is “4” (S22: YES), since the random number for this game ball cannot be stored, the process proceeds to S25 as it is.

  When the value of the special symbol operation reserved ball number storage area 5206 is not “4”, that is, any of “0” to “3” (S22: NO), the special symbol operation reserved ball number storage area 5206 “1” is added to the value (S23). And a random number is memorize | stored in the storage area of the number corresponding to the value of the special symbol action reservation ball number storage area 5206 among the 1st storage area-the 4th storage area of the jackpot relation information storage area 5205 (S24). Specifically, the value of the jackpot determination counter is in the jackpot random number column, the value of the probability variation determination counter is in the probability variation random number column, the value of the round number counter is in the round number random number column, and the value in the special symbol random number column is The value of the special symbol determination counter is stored, and the value of the variation pattern determination counter is stored in the variation pattern random number column.

  Next, it is determined whether or not the jackpot gaming state is based on the jackpot gaming state flag (S25). When it is a jackpot game state, the jackpot determination and the notification of the determination result are not performed. Therefore, when the jackpot gaming state flag is ON and the jackpot gaming state is set (S25: YES), the process returns to the main process without doing anything.

  If the jackpot gaming state flag is not ON (S25: NO), since it is not a jackpot gaming state, processing relating to the control of the special symbol display portions M1 and M2 is performed. First, it is determined whether or not the special symbol display portions M1 and M2 are changing based on the display state flag (S26). If the display state flag is not “1” and is not changing (S26: NO), as shown in FIG. 9, it is determined whether or not the display is stopped by the display state flag (S27). When the display state flag is not “2” and the stop display is not being performed (S27: NO), a big hit determination is performed.

  Therefore, as shown in FIG. 10, it is confirmed whether or not there is a game ball to be subjected to the jackpot determination (S28). If the value of the special symbol operation reserved ball number storage area 5206 is not equal to or greater than “1” (S28: NO), there is no game ball to be subjected to the jackpot determination, and the process directly returns to the main process. If it is equal to or greater than “1” (S28: YES), there is a game ball for which a jackpot determination is to be made. The value stored in area 5205 is shifted. That is, the random number stored in the first storage area is shifted to the determination area, the random number stored in the second storage area is shifted to the first storage area, and the random number stored in the third storage area is The random number is shifted to the second storage area, the random number stored in the fourth storage area is shifted to the third storage area, and the value of the fourth storage area is cleared (S30).

  Next, a jackpot determination is performed, whether it is a probability variation, a round number determination, or a medium hit determination is performed, and a combination of special symbols and a variation pattern corresponding to each are determined (S31 to S44). First, it is determined whether or not the jackpot random number (the value in the jackpot random number column of the determination area) satisfies the jackpot condition (S31). The jackpot condition is that the jackpot random number is a specific value determined as “jackpot”, for example, “7”. When the probability variation flag is ON and the state is a high probability state, the specific value that is a big hit is not limited to “7”, but a plurality of values, for example, big hit random numbers “3”, “7”, “ 33 ”,“ 77 ”,“ 177 ”, and the probability of a big hit increases.

  If it is determined that it is a big hit (S31: YES), whether the value per random change is based on whether or not the value of the random number per probability change is a specific value determined in advance as "per probability change" A determination of whether or not is made (S33). If it is not per probability variation (S33: NO), it will be per 15R non-probability variation, so it is based on the special symbol random number from the “special symbols per 15R non-probability variation” stored in the special symbol combination storage area 5304. One special symbol combination is determined, and a command indicating the special symbol combination is stored in the command relation storage area 5207 (S39). Then, a fluctuation pattern is determined based on the value of the fluctuation pattern random number from the hit fluctuation pattern storage area 5306, and a command indicating the fluctuation pattern is stored in the command relation storage area 5207 (S40). Then, the process proceeds to S45.

  Further, when it is determined that it is per probability fluctuation (S33: YES), it is determined whether it is per 15R probability fluctuation or per 2R probability fluctuation (S34). It is determined whether or not the value of the round number random number is a specific value that is determined in advance as “15R”. One special symbol combination is determined based on the special symbol random number from the “special symbols per 15R probability change” stored in the special symbol combination storage area 5304, and a command indicating the special symbol combination is displayed in the command relation storage area 5207. (S41). Then, a fluctuation pattern is determined based on the value of the fluctuation pattern random number from the hit fluctuation pattern storage area 5306, and a command indicating the fluctuation pattern is stored in the command relation storage area 5207 (S42). Then, the process proceeds to S45.

  If it is determined that it is not 15R (S34: NO), since it is per 2R probability variation, a special symbol random number is selected from the “special symbols per 2R probability variation” stored in the special symbol combination storage area 5304. Based on the above, one special symbol combination is determined, and a command indicating the special symbol combination is stored in the command relation storage area 5207 (S43). Then, the variation pattern is determined from the sudden variation pattern storage area 5307 based on the value of the variation pattern random number, and a command indicating the variation pattern is stored in the command relation storage area 5207 (S44). Then, the process proceeds to S45.

  If it is determined in S31 that it is not a big hit (S31: NO), it is determined whether or not it is a middle win (S32). When the jackpot random number is a specific value determined as “medium hit” (a value other than the specific value set as jackpot), it is determined as “medium hit”. If it is determined that it is a middle hit (S32: YES), one special symbol combination is determined based on the special symbol random number from the “mid bonus special symbol” stored in the special symbol combination storage area 5304, A command indicating the special symbol combination is stored in the command relation storage area 5207 (S37). Then, the variation pattern is determined from the sudden variation pattern storage area 5307 based on the value of the variation pattern random number, and a command indicating the variation pattern is stored in the command relation storage area 5207 (S38). Then, the process proceeds to S45.

  Further, when it is neither a big hit nor a middle hit (S31: NO, S32: NO), it is a loss, so that it is based on a special symbol random number from the “special symbol combination” stored in the special symbol combination storage area 5304. One special symbol combination is determined, and a command indicating the special symbol combination is stored in the command relation storage area 5207 (S35). Then, a fluctuation pattern is determined from the deviation fluctuation pattern storage area 5305 based on the value of the fluctuation pattern random number, and a command indicating the fluctuation pattern is stored in the command relation storage area 5207 (S36). Then, the process proceeds to S45.

  Then, the symbol designation command set in S35, S37, S39, S41, and S43 is transmitted not only to the sub-integrated board 58 but also to the symbol display board 44 in the command output process (S10) of the main process to be executed next. Is done. Then, the variation pattern designation command set in S36, S38, S40, S42, and S44 is transmitted in the command output process (S10) of the main process performed next. In the symbol display board 44 that has received these commands, the special symbol display portions M1 and M2 start to change. Therefore, in S45, “1” indicating that the display state flag is changing is set (S45). Then, in order to start measuring the variation time, the variation time determined for each variation pattern is stored in the special symbol variation time counter (S46). Then, the process returns to the main process.

  In the special symbol process in the main process to be performed next, since the game ball has not won (S21: NO), the process proceeds to S25 as it is. And it is not a jackpot gaming state (S25: NO). However, since “1” is stored in the display state flag and the special symbol display portions M1 and M2 are changing (S26: YES), it is determined whether or not the changing time has passed (S50). . This determination is made based on the value of the special symbol variation time counter. If the value of the special symbol variation time counter is not “0” and the variation time has not yet elapsed (S50: NO), the variation of the special symbol display portions M1 and M2 is continued. Therefore, the special symbol process is terminated and the process returns to the main process.

  When the main process is repeated and the value of the special symbol variation time counter becomes “0” and the variation time of the special symbol display portions M1 and M2 has elapsed (S21: NO, S25: NO, S26: YES, S50: YES). ) All symbol stop commands are stored in the command relation storage area 5207 (S51). Then, a predetermined stop display time (for example, 3 seconds) is stored in the special symbol stop time counter (S52), and “2” indicating that the special symbol display portions M1 and M2 are in stop display is displayed in the display state flag. Stored (S53). Then, the special symbol process is terminated and the process returns to the main process.

  In the special symbol process in the main process to be performed next, since the stop display is being performed (S21: NO, S25: NO, S26: NO, S27: YES), it is determined whether or not the stop display time has elapsed. Performed (S54). This determination is made based on the value of the special symbol stop time counter. When the value of the special symbol stop time counter is not “0” and the stop display time has not yet elapsed (S54: NO), the symbols are continuously stopped and displayed on the special symbol display portions M1 and M2. Therefore, the special symbol process is terminated and the process returns to the main process.

  Then, the main process is repeated, and when the value of the special symbol stop time counter becomes “0” and the stop display time of the special symbol display portions M1 and M2 has elapsed (S21: NO, S25: NO, S26: NO, S27: (YES, S54: YES), “0” indicating that the special symbol display portions M1 and M2 are not in the stop display or in the fluctuation state is stored in the display state flag (S55). Then, when the result of the jackpot determination is “big jackpot” (S56: YES), the jackpot game state flag is set to ON (S57), and control is performed so that the jackpot game is started from the next main process. Then, the probability variation flag is turned off (S58), the jackpot game screen start command is stored in the command relation storage area 5207 (S59), and the process returns to the main process. If it is not a big hit (S56: NO), the special symbol process is terminated as it is, and the process returns to the main process.

  As described above, when the game ball wins the special symbol start electric accessory 15 (S21: YES), various random numbers are acquired (S24), the big hit determination is performed (S31 to S34), the fluctuation pattern and the special The symbols displayed on the symbol display portions M1 and M2 are determined, and a control command for starting the change to the sub-integrated board 58 is stored (S35 to S44). And while the main process is repeatedly performed, the special symbol process is also repeatedly performed, and when the variation time has elapsed (S21: NO, S25: NO, S26: YES, S50: YES), control for stopping the variation. The command is stored (S51), and a stop display is performed. Furthermore, when the special symbol processing is repeatedly performed and the stop display time elapses (S21: NO, S25: NO, S26: NO, S27: YES, S54: YES), the notification of the jackpot determination result is terminated and the jackpot is won. In this case, the jackpot gaming state flag is turned ON in order to shift to the jackpot gaming state (S55). Then, the process returns to the main process.

  Next, details of the special electric accessory process (S13) of the main process will be described with reference to the flowchart shown in FIG. In the special electric accessory processing, the operation of the big hit gaming state such as opening / closing of the special winning opening 16 is controlled. In the big hit gaming state, the big winning opening 16 is opened and is closed when a predetermined time elapses or when a predetermined number (for example, 10 balls) of winning balls is detected. After the special winning opening 16 is closed, the opening is performed again until the predetermined number of times is opened. In the present embodiment, the predetermined time is 30 seconds per 15R probability fluctuation and per 15R non-probability fluctuation, and the predetermined number of times is 15 times. The predetermined number of times is 0.3 seconds and is twice.

  First, flags and counters used in the special electric accessory processing will be described. Here, a jackpot gaming state flag, an opening flag, an opening number counter, an opening time counter, a closing time counter, and the like are used. The jackpot game state flag is the same as the special symbol process. The opening flag is a flag indicating whether or not the special winning opening 16 is being opened, and “1” is stored and ON during opening, and “0” is stored during closing. It is OFF. The number-of-opening counter is a counter for counting the number of times that the big winning opening 16 is opened during one big hit gaming state. The opening time counter is a counter for measuring the time during which the special winning opening 16 is opened. The closing time counter is a counter for measuring the time during which the special winning opening 16 is closed. Note that the initial value of the opening flag is “0”, and the values of the opening number counter, the opening time counter, and the closing time counter are “0”.

  As shown in FIG. 11, when the special electric accessory processing is started, first, it is determined whether or not the jackpot gaming state is based on the jackpot gaming state flag (S101). If the jackpot game state flag is OFF and the jackpot game state is not set (S101: NO), there is no need to process the jackpot game, so the process is terminated without doing anything and the process returns to the main process.

  In the special electric accessory process that is executed first in the jackpot gaming state, the value of the release flag is “0”, the number of times of opening counter, the opening time counter and the closing time counter are “0”, and the jackpot gaming state flag is Since it is ON, it is determined that it is a jackpot gaming state (S101: YES), it is not being opened (S102: NO), the closing time has elapsed (S112: YES), and the specified number of times of opening has not ended. (S114: NO), a special winning opening opening process is performed (S115). Specifically, a big winning opening release command indicating opening of the big winning opening 16 to the sub integrated board 58 and a big winning start command indicating the start of the big winning gaming state are stored in the command relation storage area 5207. In addition, “1” is stored in the opening number counter, the opening flag is turned ON, a predetermined opening time of the big winning opening 16 is stored in the opening time counter, and “0” is stored in the winning ball counter. Then, the process returns to the main process. Note that for each 15R random fluctuation and for each 15R non-probabilistic fluctuation, "15000" indicating 30 seconds is stored in the open time counter, and "150" indicating 0.3 seconds is stored per 2R random fluctuation and in the middle. The

  In the special electric accessory process executed in the next main process, the jackpot gaming state flag and the release flag are set to ON (S101: YES, S102: YES), so it is determined whether or not the release time has elapsed. Performed (S107). The special winning opening 16 has just been opened in the previous electric accessory processing, and the opening time counter is not “0”, and it is determined that the opening time has not elapsed (S107: NO). Then, a determination is made as to whether or not a game ball has won a prize winning opening 16 (S108). When the count switch 75 provided in the big winning opening 16 detects winning of a game ball, the flag corresponding to the count switch 75 in the winning ball flag storage area 5202 is ON. Therefore, when the flag corresponding to the count switch 75 is ON (S108: YES), “1” is added to the winning ball counter, and the big winning opening winning ball number adding process is performed (S109). If the flag corresponding to the count switch 75 is not ON (S108: NO), the addition process is not performed. Then, it is confirmed whether or not a predetermined number of game balls have won the big winning opening 16 based on the value of the winning ball counter (S110). The big winning opening 16 has just been opened in the previous electric game process, and since the value of the winning ball counter is not a predetermined number (for example, 10 balls) or more (S110: NO), the process directly returns to the main process.

Then, the main process is repeatedly performed and the release time has elapsed (S101: YES, S102: YES, S107: YES), or when a prescribed number of game balls are won (S101: YES, S102: YES, S107: NO, (S110: YES), since the special winning opening 16 is closed, the special winning opening closing process is performed (S111). Here, the open flag is turned OFF is stored is "0", "1" is added to the open counter. Then, the special electric accessory process is terminated and the process returns to the main process.

  Then, when the next special electric accessory processing of the main processing is performed, the jackpot gaming state is in effect (S101: YES), and the big winning opening 16 is not open (S102: NO), so whether the closing time has elapsed A determination of whether or not is made (S112). If the closing time has not yet elapsed (S112: NO), the special electric accessory process is terminated as it is, and the process returns to the main process.

  When the main process is repeatedly performed and the closing time has elapsed (S101: YES, S102: NO, S112: YES), it is determined whether or not the specified number of times has been released (S114). Here, the “specified number of times” is 15 times per 15R probability fluctuation and 15R non-probability fluctuation, and 2 times per 2R probability fluctuation and medium hit in this embodiment. Since only one opening has been completed, the predetermined number of times has not been opened (S114: NO), and the big prize opening process is performed (S115). Then, the special electric accessory process is terminated and the process returns to the main process.

  When the main process is repeatedly performed and the predetermined number of times is released (S101: YES, S102: NO, S112: YES, S114: YES), the jackpot gaming state is terminated, so the jackpot gaming state flag is turned OFF. (S116). Then, a determination is made as to whether or not the jackpot that caused the jackpot game was per probability change (S117). If it is per probability change (S117: YES), the probability change flag is turned ON (S118), and the special electric accessory processing end process is performed (S120). Specifically, “0” is stored in the release number counter, and the jackpot end screen display command is stored in the command relation storage area 5207. If not per probability change (S117: NO), the probability change flag is turned OFF (S119), and the special electric accessory processing end process is performed (S120). In this way, the jackpot game is executed.

  Next, sub integrated substrate processing performed by the CPU 581 of the sub integrated substrate 58 will be described with reference to FIG. In the sub-integrated board processing, in response to a control command sent from the main board 41, various commands are added to give detailed instructions to the sound board 43, the symbol display board 44, and the electrical decoration board 46. Here, it demonstrates centering on control of the demonstration symbol display parts L1-L3 regarding the notification of the result of jackpot determination. FIG. 12 is a flowchart of sub integrated substrate processing performed by the CPU 581 of the sub integrated substrate 58.

  The ROM 583 of the sub-integrated board 58 has an initial setting storage area for storing an initial value stored in each storage area when the pachinko machine 1 is reset, and various controls for the CPU 581 to assist the control of the pachinko machine 1. A control program storage area for storing a program, a control command table storage area for storing a table of control commands output from the sub-integrated board 58 to the sound board 43, the symbol display board 44, and the electrical decoration board 46, and information relating to variation patterns are stored. There are provided a variation pattern storage area, an effect pattern storage area in which an effect pattern indicating a finer effect (type of character to be displayed, movement, etc.) is stored based on the change pattern.

  The RAM 582 also has a counter storage area for storing various counters used in the sub-integrated substrate processing, a flag storage area for storing various flags used in the sub-integrated substrate processing, and notification of the result of the jackpot determination. A command storage area for storing control commands received from the main board for execution is provided. The counter storage area stores a first demo symbol determination counter, a second demo symbol determination counter, and a third demo symbol determination counter which are counters for determining the demo symbols to be displayed on the demo symbol display portions L1 to L3. Has been.

  The first demo symbol determination counter is used to determine a demo symbol displayed on the demo symbol display unit L1, and is incremented by “1” every 2 ms with an initial value “0” and becomes a value of “9” or more. Return to “0” and take values from “0” to “9”. The second demo symbol determination counter is used to determine the demo symbol displayed on the demo symbol display unit L2, and when the initial value is “0”, “1” is added every 20 ms and becomes “9” or more. Return to “0” and take values from “0” to “9”. The third demo symbol determination counter is used to determine a demo symbol displayed on the demo symbol display unit L3. When the initial value is “0”, “1” is added every 200 ms and becomes “9” or more. Return to “0” and take values from “0” to “9”.

  Next, the sub integrated substrate processing shown in FIG. 12 will be described. The sub-integrated board processing is executed after power is turned on to the sub-integrated board 58 and initial processing such as operation confirmation of the RAM 582 and ROM 583 and initial value setting such as various flags and counters is completed. First, it is determined whether or not a variation pattern designation command has been received from the main board 41 (S201).

  When the variation pattern designation command is received (S201: YES), the result of the jackpot determination is notified according to the designated variation pattern. Therefore, in addition to the production conditions such as whether or not to perform the special symbol variation time and reach operation specified by the variation pattern, whether a specific character is displayed on the symbol display screen 28, or what kind of movement the character has An additional effect condition (effect pattern) such as whether or not to perform is determined, and a command corresponding to the effect pattern is created as a subsequent command to be added to the variation pattern command (S220). Specifically, an effect pattern that can be selected for each variation pattern is determined in advance, and an effect pattern is selected from these, and a command corresponding to the effect pattern is set as a subsequent command. Then, the variation pattern command is transmitted to the sound board 43, the symbol display board 44, and the electrical decoration board 46 (S221), and the subsequent command is transmitted to the sound board 43, the symbol display board 44, and the electrical decoration board 46 (S222). Then, the process returns to S201.

  If the variation pattern designation command has not been received (S201: NO), it is determined whether or not a special symbol designation command has been received (S202). The special symbol designating command for detachment is transmitted from the main board 41 next to the variation pattern designating command when the result of the jackpot determination is “missing” and “missing” is also determined in the middle hitting determination. When the special symbol designating command is received (S202: YES), the demo symbols displayed on the demo symbol display portions L1 to L3 are determined, and commands indicating those symbols are transmitted to the symbol display board 44 (S211). Then, the process returns to S201.

  The demo symbols displayed on the demo symbol display portions L1 to L3 are determined by reading the values of the first demo symbol determination counter, the second demo symbol determination counter, and the third demo symbol determination counter. Here, when the values of the demo symbol display portions L1 to L3 are in order or in a rough pattern, a value obtained by adding “1” to the third demo symbol determination counter (if “10” or more, “ 0 ") is the value displayed on the demo symbol display portion L3. If the variation pattern received in S201 is a variation pattern for performing a reach operation, the demonstration symbol displayed on the demonstration symbol display unit L2 is also determined by the value of the first demonstration symbol determination counter, and the demonstration symbol display unit L1. And L2 so that the same symbol is displayed.

  If no special symbol designation command has been received (S202: NO), it is determined whether a 15R non-probability variation special symbol designation command has been received (S203). This 15R non-probability variation special symbol designation command is transmitted from the main board 41 next to the variation pattern designation command when the result of jackpot determination is “15R non-probability variation jackpot”. When the 15R non-probability variation special symbol designation command is received (S203: YES), symbols to be displayed on the demo symbol display portions L1 to L3 are determined so as to be even numbers, and a command indicating those symbols is displayed. It is transmitted to the display substrate 44 (S212). Then, the process returns to S201. The demo symbols displayed on the demo symbol display portions L1 to L3 are determined by reading the value of the first demo symbol determination counter. Here, when the value of the first demo symbol determination counter is an odd number, a value obtained by adding “1” to the first demo symbol determination counter (“0” if “10”) is the demo symbol display portion L1. It is set as the value displayed in ~ L3.

  If the 15R non-probability variation special symbol designation command has not been received (S203: NO), it is determined whether or not the 15R probability variation special symbol designation command has been received (S204). This 15R probability variation special symbol designation command is transmitted from the main board 41 next to the variation pattern designation command when the result of jackpot determination is “15R probability variation jackpot”. When the 15R probability variation special symbol designation command is received (S204: YES), symbols to be displayed on the demo symbol display portions L1 to L3 are determined so as to be odd numbers, and a command indicating these symbols is displayed. It is transmitted to the substrate 44 (S213). Then, the process returns to S201. The demo symbols displayed on the demo symbol display portions L1 to L3 are determined by reading the value of the first demo symbol determination counter. Here, when the value of the first demo symbol determination counter is an even number, the value obtained by adding “1” to the first demo symbol determination counter is the value displayed on the demo symbol display portions L1 to L3.

  If the 15R probability variation special symbol designation command has not been received (S205: NO), it is determined whether or not a mid hit special symbol designation command has been received (S205). This mid-hit special symbol designation command is transmitted from the main board 41 next to the variation pattern designation command when the result of the big-hit determination is “out of” and “hit” in the middle-hit determination. When a special bonus designating command is received (S205: YES), symbols to be displayed on the demo symbol display portions L1 to L3 are determined so as to be in order, and commands indicating those symbols are transmitted to the symbol display board 44. (S214). Then, the process returns to S201. The demo symbols displayed on the demo symbol display portions L1 to L3 are determined by reading the value of the first demo symbol determination counter. The demo symbol display portion L1 has a demo symbol of the value of the first demo symbol determination counter, the demo symbol display portion L3 has a demo symbol of a value obtained by adding “1” to the first demo symbol determination counter, and the demo symbol display portion. L2 is a demo symbol having a value obtained by adding “2” to the first demo symbol determination counter. Here, when the value of the first demo symbol determination counter is “8” or “9”, the demo symbol display portions L1, L3, and L2 are set to “1, 2, 3”.

  On the other hand, when the special bonus designating command is not received (S205: NO), it is determined whether or not the 2R probability variation special symbol designating command is received (S206). This 2R probability variation special symbol designation command is transmitted from the main board 41 next to the variation pattern designation command when the result of jackpot determination is “2R probability variation jackpot”. When the 2R probability variation special symbol designation command is received (S206: YES), the symbols displayed on the demo symbol display portions L1 to L3 are determined so as to be in order, as in the case of the middle hit. The command shown is transmitted to the symbol display board 44 (S214). Then, the process returns to S201.

  If the 2R probability variation special symbol designation command has not been received (S206: NO), it is determined whether or not all symbol stop commands have been received (S207). This all symbol stop command is transmitted from the main board 41 when the special symbol display portions M1 and M2 are stopped. Therefore, when all symbols stop command is received (S207: YES), the command is further transmitted to the sound board 43, the symbol display board 44, and the illumination board 46 (S215). Then, the process returns to S201.

  If all symbol stop commands have not been received (S207: NO), it is determined whether or not a jackpot game start screen command has been received (S208). The jackpot game start screen command is transmitted from the main board 41 when the jackpot game for opening the jackpot 16 is started. Therefore, when a jackpot game start screen command is received (S208: YES), a jackpot game screen selection process is performed (S216).

  As described above, in the gaming machine of the present embodiment, there are 15 open jackpot games (15R jackpot game), two open jackpot games (2R jackpot game), and two open games depending on the type of jackpot A winning game is provided. In the 2R jackpot game and the medium hit game, the same game is performed in which the big prize opening 16 is opened twice for 0.3 seconds. Therefore, in S216, it is determined whether or not the game is a 15R jackpot game depending on the type of the received special symbol designation command. If it is a 15R non-probability variation special symbol designation command or a 15R probability variation special symbol designation command, a 15R jackpot is determined. A command for playing a game is transmitted to the sound board 43, the symbol display board 44, and the illumination board 46 (S217). In this 15R jackpot game, the game ball can be won by opening the grand prize winning opening 16, and a special effect that appeals that a large number of game balls can be acquired is a special symbol display device 8, various illumination lamps 63, and others. Sound effect and music flow from the speaker 48.

  Further, if the 2R probability variation special symbol designation command or the middle hit special symbol designation command, a command for displaying “chance!” On the special symbol display screen 28 while two releases are performed is the symbol display board 44. (S217). In the present embodiment, the 2R jackpot game is a short game of about 1 second (the release of 0.3 seconds is 2 times), and the special symbol display screen 28 is not used to give a flashing appeal that the jackpot game is being played. Only the word “chance!” Is displayed.

  If the jackpot game start screen command has not been received (S208: NO), it is determined whether or not the jackpot game end screen command has been received (S209). When the jackpot game end screen command is received (S209), a command for terminating the jackpot game or “chance!” Display is displayed on the sound board 43, the symbol display board 44, and the electrical board 46. Transmitted (S218)

  If the jackpot game end screen command has not been received (S209: NO), other processing is performed (S219), and the process returns to S201. In this other processing, processing such as reception of a command for instructing timing of opening and closing of the prize winning opening 16 and transmission of instruction commands to the other sound board 43, symbol display board 44, and illumination board 46 are performed. Is called.

  By repeating these processes, the sub-integrated board 58 processes the control command sent from the main board 41 and gives instructions to the sound board 43, the symbol display board 44, and the illumination board 46.

  The start port switch 72 of the above embodiment corresponds to “game ball detecting means”, the special symbol display portions M1 and M2 correspond to “special symbol display means”, the special symbol display device 8, the LED 62, and the illumination. The lamp 63 and the speaker 48 correspond to “effect members”, and the demo symbol display portions L1 to L3 correspond to “demo symbol display means”. Further, the deviation variation pattern storage area 5305, the hit variation pattern storage area 5306, and the sudden probability variation pattern storage area 5307 of the ROM 53 of the main board 41 correspond to the “variation pattern storage unit”. The storage area corresponds to “production pattern storage means”.

  Further, the CPU 51 that performs the process of S24 of the special symbol process shown in FIG. 9 corresponds to “random number acquisition means”, and the CPU 51 that performs the process of S31 of the special symbol process shown in FIG.

  The present invention is not limited to the embodiment described in detail above, and various modifications can be made. It goes without saying that the gaming machine of the present invention is not limited to a pachinko machine, but may be various gaming machines that use gaming media, such as a pachikon machine or a pachislot machine.

  In the above embodiment, the order is displayed on the demo symbol display portions L1 to L3 in the case of the 2R probability fluctuation big hit and mid hit, but the combination of symbols displayed on the demo symbol display portions L1 to L3 is not limited to this. . Further, the “demo symbol display means” may not be a combination of three symbols, but may be a character such as an illustration, an alphabet, a symbol, or the like instead of a number.

  Moreover, in the above embodiment, in the game of mid-win game and the game of sudden probability change big game (2R probability variation jackpot) game that performs the same game as the mid-game, the big winning opening 16 is opened twice for 0.3 seconds. The number of times of opening is not limited to this, and it may be more or less than this, and preferably it is a time shorter than the time interval of game ball launch when game balls are fired continuously. Good. If it is shorter than the firing time interval, there is a very low possibility that the game ball will win the grand prize opening 16, and the game ball will win the big prize opening 16 and the prize balls will not be paid out. As a result, the player is not perceived that the jackpot game has been played.

  However, even if the opening time of the big prize opening 16 is short, the game ball may win the big prize opening 16. For example, if the time (arrival time) from when a game ball is launched until it flows down to the grand prize opening 16 is almost uniform, the game ball reaches the big prize opening 16 at the timing when the big prize opening 16 is opened. The ball will win only if it is. In addition, when the arrival time of the game ball that has been launched next to the game ball is shorter than the arrival time of the game ball that has just reached the prize winning port 16 at the timing when the grand prize opening 16 is released, the firing time In some cases, two game balls may reach the grand prize winning opening 16 in a time shorter than the interval. In such a case, two game balls will win. For the same reason, there may be a case where three game balls arrive at the big winning opening 16. However, it is rare for the game ball to reach the big prize opening 16 at the timing when the big prize opening 16 is opened. Further, even if the game balls arrive at the opening timing of the big winning opening 16, only a few game balls can be won, and a large number of game balls cannot win, so a large number of game balls Will not be paid out. Therefore, when a large number of game balls are paid out to the player, it is not detected that a big hit game has been performed.

  Further, the number of times of opening may not be fixed, but may be selected from a plurality of times by lottery. In that case, the same number of times may be included in the number of times selected in the sudden hit game with the odd change and the number of times selected in the mid game. For example, if the jackpot of sudden probability change, select from 2, 3, 4 and 5 times, and select from 1, 2, 3, and 4 times in the middle hit. Further, in this case, the selection of each number of times may be biased so that the degree of expectation that it is a big hit of sudden probability change may be known based on the number of times the big winning opening 16 is opened. For example, in the case of the above-mentioned example, the probability of selecting 2 times is 40% in the case of sudden probability change jackpot, the probability of selecting 3 times is 40%, the probability of selecting 4 times is 10%, the probability of selecting 5 times Is 10%, the probability of selecting once is 20%, the probability of selecting 2 times is 20%, the probability of selecting 3 times is 20%, and the probability of selecting 4 times is 40%, When the winning prize opening 16 is opened 2, 3, 5 times, the expectation level is high, and when it is opened 1, 4 times, the expectation level is high.

  Further, in the above embodiment, the variation pattern is selected from the same sudden probability variation pattern storage area 5307 for the sudden probability variation jackpot and middle hit, but it is not always necessary to select from the same group variation pattern. You may choose from a separate group containing That is, a sudden hit variation pattern storage area for large hits and a mid-range variation pattern storage area are provided so as to include the same variation pattern. For example, if the number of the variation pattern included in the former is 1 to 20, the number of the variation pattern included in the latter is 3 to 22. Thus, there may be only overlapping numbers, or one may be included in the other so that the latter variation pattern number is 3-10.

  In the above embodiment, the production pattern is selected from the group corresponding to the variation pattern. Therefore, the effect pattern to be selected is selected from the same set even in the big hit and the middle win in which the same game as the middle win is performed. However, the effect pattern may not be determined for each variation pattern, but may be determined according to the type of winning.

  Further, in the above embodiment, a game in which the big winning opening 16 is opened the same number of times for a part of the probability fluctuation jackpot and the middle hit, but when the same game as the middle hit is performed, the probability fluctuation jackpot Not exclusively. It may be a part of a jackpot that shortens the fluctuation time of the special symbol display parts M1 and M2, may be a part of a jackpot that shortens the fluctuation time of the normal symbol display part 24, or a winning per ordinary prize It may be a part of a jackpot that changes the probability, or a part of a jackpot that lengthens the opening time of the pair of opening and closing members provided in the special symbol starting electric accessory 15 by a normal hit. Or just a jackpot.

  Moreover, in the said embodiment, when it becomes 2R probability fluctuation jackpot, it has not alert | reported that it shifted to the high probability state, but you may alert | report. The notification timing may be when the jackpot game is over and the state is shifted to a high probability state, may be when notification of the result of the next jackpot determination is started, or any timing It may be. In addition, a lottery of whether or not to make a notification may be performed, and the notification may be performed only when the lottery is won. Moreover, you may draw lots the timing which performs alerting | reporting. Even if the notification method is direct such as displaying the character “high probability!” On the special symbol display screen 28, a specific lamp is lit or blinked, or a specific character is displayed as a special symbol. It may be performed indirectly such as being displayed on the screen 28, playing specific music, or vibrating the launch handle 7.
