Description

  The present invention relates to a pachinko machine that uses a game ball to play a game, and more particularly to a pachinko machine that produces an effect that makes it difficult to recognize a game state after a big hit.

  In general, a pachinko machine is provided with a special symbol display device that displays a special symbol in a game area in the game board, an effect display device that displays a predetermined effect, and a starting point that triggers an electronic lottery related to the special symbol. In addition, when a game ball launched toward the game area wins the start opening, an electronic lottery related to the special symbol is performed, and the special symbol display device displays a mode of stopping after changing the special symbol. To go and inform the result of the electronic lottery.

  Further, in synchronization with the variable display of the special symbol, a plurality of effect symbols (designated as a dummy symbol, which is used for the effect) are displayed in a variable manner on the effect display device so that various effects are performed. When the result of the electronic lottery is a big hit (per special figure), these effect symbols are stopped and displayed in a predetermined stop mode (for example, a mode in which three identical symbols stop together). Thus, the player is notified that it is a big hit. When the jackpot is won, a jackpot game advantageous to the player is provided. In this jackpot game, the game device enters the winning prize opening that is exposed by opening and closing the attacker device a predetermined number of times, so that the player can acquire many prize balls.

  The above jackpots include normal hits, probability hits, and small hits that are more advantageous to the player than the normal hits. Depending on the type of jackpot, the gaming state related to the special symbol after the jackpot game is the normal state (special figure) The normal game state) or a transition to a probability variation state in which the probability of winning a big hit is higher than the normal state. Then, when winning the winning game, the player is entertained by performing an effect (for example, changing the background color) indicating the probability variation state on the effect display device after the jackpot.

  Also, in recent years, it has been made difficult to understand whether the gaming state related to the special symbol is a normal state or a probability variation state, and the player is expected to expect the current gaming state to be a probability variation state. Pachinko machines have also appeared. Specifically, the player can recognize the game state by performing the same effect (for example, the same background color) in the normal state and the probability variation state on the effect display device after the big hit. Making it difficult. Therefore, the player proceeds with the game for a while while expecting to be in the probability variation state.

  In addition, although it is not possible to distinguish between the normal state and the probability variation state on the stage of production, a specific gaming state that is actually a probability variation state is called `` latency probability variation '' after the state that the probability variation state is lurking. Therefore, in this specification, such a specific gaming state will be referred to as “latency probability change” as appropriate.

  By the way, in this latent probability variation state, even if the gaming state related to the special symbol is in the probability variation state, the player cannot judge that, so the expectation for the jackpot despite being in the probability variation state The feeling could not be sustained. In some cases, the player may be bored with the production that does not shine instead of changing the latent probability and stop playing.

  As an example of a pachinko machine that attempts to solve such a problem, for example, the one described in Patent Document 1 is known. The pachinko machine described in Patent Document 1 has a plurality of effect modes, and is configured to perform effect mode transition lottery at a predetermined timing and shift the effect mode according to the lottery. And the probability of the lottery for transition to each production mode is set to be different between the latent probability changing state and the normal state. That is, there are provided an effect mode that easily shifts in the latent probability change and an effect mode that easily shifts in the normal state. Therefore, the player can predict to some extent accurately whether the current game state is the latent probability changing state or the normal state by looking at the transitioned effect mode. And when it transfers to the production mode with high possibility of latent probability change, the player can enjoy a game, raising the expectation to the next jackpot.

JP 2010-158430 A (paragraphs 0168 to 0170, etc.)

However, with new pachinko machines appearing in the market one after another, as in Patent Document 1, it is no longer possible for the production to suggest whether or not the latent probability changes depending on the transition destination of the production mode (that is, the display mode of the production). Attracting players is no longer possible. Therefore, the advent of a pachinko machine that makes a suggestion of an attractive gaming state that can attract players is awaited.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a pachinko machine that provides an attractive game state suggestion effect that can attract a player .

In order to achieve the above object , the present invention provides a game board having a game area in which game balls flow down, a start opening and a through chucker provided in the game area, and a game ball winning in the start opening. A special symbol lottery means for performing a lottery related to success or failure, a jackpot game control means for providing any one of a plurality of types of jackpot games when the special symbol lottery is won per lottery by the special symbol lottery means, and the through A normal symbol lottery means for performing a lottery based on the passing of a game ball through the chucka and an opening at the entrance of the start opening, and opens and closes when a lottery by the normal symbol lottery means is won per a regular figure. An electric winning device that makes it easy to win the game ball at the start opening, an effect display device that displays a predetermined effect based on the lottery result of the special symbol lottery means, and the effect display device And a special display normal gaming state in which the winning probability per special figure by the special symbol lottery means is a normal special game state, and the special figure normal gaming state. A probability variation state with a higher winning probability per special figure is prepared, and as a gaming state related to a normal symbol, the winning probability per ordinary symbol by the normal symbol lottery means is a normal normal figure normal gaming state A game state setting means for setting a game state related to the special symbol and a game state related to the normal symbol, wherein a short-time game state having a higher winning probability per the general symbol than the normal symbol normal game state is prepared. The effect display control means displays the game state set based on the game state setting means after the jackpot game is finished on the effect display device in a manner in which it is difficult for the player to identify. In the configuration the pinball machine as, wherein the plurality of types of jackpot gaming, the attainable prizes counts of the player in the bonus game than the first Daito was Ri groups or the first jackpot a predetermined number of groups includes those belonging to any of the winning balls large number second jackpots group, wherein the first Daito was Ri group, a gaming state of the special symbol after the jackpot gaming is the special symbol normal gaming state And a game state relating to a first jackpot game in which the time-short game is played Na times (where Na is a natural number) after the jackpot game and a special symbol after the jackpot game Is set to the probability variation state, and the second jackpot game in which the short-time game is played Nb times (however, a natural number satisfying Nb> Na) after the jackpot game, Belongs and, wherein the second Daito was Ri groups, although the time-shortening game after the bonus game is jackpot game played the Nb times belong, jackpot gaming that the time reduction gaming takes place the Na times belongs to The probability that the jackpot game control means provides the second jackpot game is higher than the probability that the jackpot game control means provides the first jackpot game, and the game state setting means is provided by the jackpot game control means. According to the type of the jackpot game, the game state related to the special symbol and the game state related to the normal symbol after the jackpot game ends are set.
In the above structure, wherein the first Daito was Ri groups, together with the gaming state of the special symbol after the big hit game is set in the probability change state, the time-shortening game after the bonus game is the Na times A third jackpot game to be played, and a game state related to the special symbol after the jackpot game is set to the special figure normal game state, and the short-time game is played Nb times after the jackpot game, , And the probability that the jackpot game control means provides the first jackpot game is higher than the probability that the fourth jackpot game is provided, and the probability that the third jackpot game is provided is the second jackpot game. It is characterized by being lower than the probability of providing

According to the present invention, the probability of providing the first jackpot game among the first jackpot group having a predetermined number of winning balls (for example, the number of rounds of jackpot round Ra) is higher than the probability of providing the fourth jackpot game. The probability of providing the third jackpot game is lower than the probability of providing the second jackpot game, so that the player depends on the special symbol after the jackpot game depending on how many times the short time is executed. It is possible to predict what the gaming state is. Therefore, according to the present invention, it is possible to provide an effect related to suggestions that increase the player's expectation.

The game area 31 is partitioned and formed into a substantially circular shape by a guide rail 32 for sliding the game ball and a game ball regulating rail 33, and the game ball launched by the launching device 9 flows down in the game area 31. To do. Further, in the game area 31, the special symbol display device 17, the effect display device 34, the through chucker 21, the normal symbol display device 22, the electric tulip (electric winning device) 49, the stage 36, and the first Start winning opening (start opening) 37a and second starting winning opening (start opening) 37b, general winning opening 38, out opening 39, game nail (not shown), windmill (not shown), and attacker A device 41 and the like are provided. The first start winning opening 37a and the second start winning opening 37b are provided with a space in the vertical direction.

  The effect display device 34 is provided in a substantially central portion of the game board 3 and is an electronic lottery for a special symbol that is performed when a game ball wins at the first start winning opening 37a and the second starting winning opening 37b. A predetermined effect mode is displayed based on the result, and a liquid crystal display device is used in this embodiment. In this effect display device 34, a background image is displayed on the entire screen, and as a part of a predetermined effect mode, a dummy symbol (effect design) is synchronized with a special symbol variably displayed on the special symbol display device 17. ) Is displayed in a variable manner. The effect display device 34 is a display for performing a hold display (display that the hold ball random number is stored) when the hold ball random number is stored in the hold ball random number storage (memory) 115a, 115b. A region is defined. That is, the display area portion is the holding ball display device 34a.

  The special symbol display device 17 is for displaying the result of the electronic lottery related to the special symbol that is performed when the game ball wins in the first start winning port 37a and the second starting winning port 37b. More specifically, the lottery result is displayed in such a manner that the lottery result is stopped after the special symbol (number or pattern) is changed. This special symbol display device 17 uses a 7-segment display in the present embodiment, and is separated from the lower right portion of the game board 3 so as not to enter the field of view of the player watching the effect display device 34 at the same time. Is provided. Then, the special symbol fluctuates by causing the 7-segment display to blink, and the blinking stops and changes to the lighting display, whereby the special symbol fluctuates. This blinking time is the special symbol fluctuation time.

  In the present embodiment, the game based on the winning of the game ball in the second start winning port 37b is executed with priority over the game based on the winning of the game ball in the first starting winning port 37a. Therefore, the lottery results of both the first start winning opening 37a and the second starting winning opening 37b are not displayed simultaneously. Therefore, the result of the lottery based on the winning of the game ball in the two start winning openings 37a and 37b is displayed on one special symbol display device 17.

  The through chucker 21 has a gate structure through which a game ball can pass, and a magnetic sensor type through chucker detection sensor 46 that detects that the game ball has passed is incorporated therein. In addition, a normal symbol display device 22 for displaying the result of the electronic lottery related to the normal symbol performed when the game ball passes through the through chucker 21 is provided next to the special symbol display device 17. . In the present embodiment, the normal symbol display device 22 is composed of two LED lamps, and one LED lamp is lit when hitting a normal figure, and the other LED lamp is lit when lost. ing. It should be noted that the normal symbol fluctuates by alternately displaying the two LED lamps in a blinking manner, and the blinking stops and the normal symbol fluctuates by changing to a lighting display. This blinking time is the normal symbol fluctuation time.

  The electric tulip 49 is provided at the entrance of the second start winning prize opening 37b, and includes a pair of blade members that rotate about an axis orthogonal to the surface of the game board 3. When the solenoid is energized, The blade members are rotated in directions away from each other, and the entrance of the second start winning prize opening 37b is enlarged. As long as the electric tulip 49 is not opened, the game ball will not win the second start winning opening 37b. Further, the stage 36 is a structure that is disposed below the effect display device 34 and in which the game ball stays temporarily while rolling. A groove is formed at the center of the stage 36, and a first start winning opening 37a is arranged at a position directly below the groove. Therefore, the game ball dropped from the groove is guided to the first start winning opening 37a with a high probability.

  As a result of the electronic lottery regarding the special symbol, which is triggered by the game ball winning in the first start winning opening 37a and the second starting winning opening 37b, the attacker device 41 is shifted to the jackpot game as a result of the special drawing. In this case, the device is opened a predetermined number of times. The attacker device 41 includes a plate-like lid member that opens and closes in the front-rear direction about a horizontal axis, and is configured to rotate around the horizontal axis by driving a solenoid (not shown). . When the lid member is opened, the big prize opening 42 provided in the lower portion of the game area 31 is exposed, and the game ball can be won through the big prize opening 42.

  That is, in the attacker device 41, since the lid member normally closes the big winning opening 42, the game ball does not win the big winning opening 42. However, as described above, when the player shifts to the jackpot game, the lid member Since the special winning opening 42 is exposed, the game ball can be awarded in the special winning opening 42. When a game ball wins the big winning opening 42, a predetermined number of game balls are paid out to the player as prize balls. That is, the player can win a game by winning a game ball in the big winning opening 42. The special winning opening 42 is a horizontally long rectangular opening, and the lid member of the attacker device 41 has substantially the same shape as that of the special winning opening 42.

  In the present embodiment, the number of times the attacker device 41 is released is standardized to 14 rounds (R). However, the number of rounds in which the player can win a prize ball, that is, the so-called round with a ball is the type of special symbol. Is different. This will be described in detail later.

  In addition, when a game ball wins the general winning opening 38, a predetermined number of game balls are paid out to the player as prize balls. The game balls that have not entered the first start winning opening 37a, the second start winning opening 37b, the general winning opening 38, and the attacker device 41 are collected from the out opening 39. It should be noted that sensors 43a, 43b, 44, 45 for detecting the passage of game balls are respectively provided in the first start winning opening 37a, the second starting winning opening 37b, the general winning opening 38, and the large winning opening 42 (FIG. 4). Reference) is provided.

  The front board 6 is provided with a receiving tray 5 that accommodates game balls and can be discharged to the outside. This tray 5 can accommodate not only game balls thrown by the player but also game balls paid out as prize balls from the prize ball payout device 14. A launching device 9 for launching game balls toward the game area 31 is attached to the lower part of the main body frame 2, and the game balls accommodated in the tray 5 are supplied to the launching device 9 one by one. The Then, when the handle 7 attached to the lower right of the front board 6 is rotated, the launching device 9 can launch the game ball to the game area 31 with a launch intensity corresponding to the turning amount.

When the CPU reads and executes various programs and data stored in the ROM, main processing relating to the game is performed.

  Specifically, as shown in FIG. 4, the main control processing unit 11 is a special symbol lottery processing unit that performs a lottery regarding whether or not a special symbol is successful when a game ball wins a winning winning opening 37a, 37b. Special symbol lottery means) 110, a special symbol type determination processing unit (special symbol type determination means) 120 for determining the type of special symbol by lottery according to the lottery result determined by the special symbol lottery processing unit 110, and a special symbol A special symbol variation pattern (PT) command determination unit 130 for determining a special symbol variation pattern command that is a command relating to the variation time of the game, and based on the fact that a predetermined condition is satisfied, The determination of the lottery result by the gaming state setting unit (gaming state setting means) 140 for setting the gaming state and the special symbol lottery processing unit 110 is per special figure. In this case, a jackpot game control unit (jackpot game control means) 160 that operates the attacker device 41 (solenoid thereof) in accordance with the type of the special symbol determined by the special symbol type determination processing unit 120 and shifts to the jackpot game is provided. ing.

  Further, the main control processing unit 11 includes a normal symbol lottery processing unit (ordinary symbol lottery means) 170 for performing lottery related to whether or not the normal symbol is passed when the game ball passes through the through chucker 21, and a normal symbol variation time. A normal symbol variation pattern (PT) command determination unit 190 for determining a normal symbol variation pattern command that is a command related to the electric tulip, and an electric tulip operation control unit 180 that controls the operation of the electric tulip 49.

  As shown in FIG. 5, the special symbol lottery processing unit 110 updates the value of the loop counter one by one within a predetermined range based on an interrupt signal periodically input (for example, every 2 milliseconds). The special symbol success / failure random number generation unit 111 for generating the first special symbol for determining whether or not the lottery for the special symbol is performed, when the game ball is won in the first start winning opening 37a. A lottery unit 119a and a second special symbol success / failure lottery unit 119b for performing a lottery concerning a special symbol and determining whether or not the game ball is won at the second start winning opening 37b are configured. ing. That is, in the present embodiment, the lottery means related to the special symbol are triggered by winning the first start winning opening 37a and triggered by winning the second starting winning opening 37b. There are two things.

  The first special symbol success / failure lottery section 119a is triggered by the fact that a game ball has won the first start winning opening 37a (at the timing when the detection signal from the starting winning opening detection sensor 43a is input to the main control processing section 11). The first special symbol success / failure determination random number acquisition unit 112a that acquires (latches) one special symbol success / failure random number generated by the special symbol success / failure determination random number generation unit 111, and the first special symbol success / failure determination random number. A first special symbol success / failure determination unit that determines whether or not the random number acquired by the acquisition unit 112a is per special symbol with reference to the first special symbol high probability determination table 116a or the first special symbol low probability determination table 117a. 113a and the first special symbol success / failure determination random number obtaining unit 112a obtain a random number, and if the special symbol is changing, the obtained random number is set as a reserved ball random number related to the special symbol. Up to four up and a (in other words, four to the upper limit is a predetermined number) first holding ball random number memory unit 115a for special symbol to be stored.

  Here, the first special symbol high probability determination table 116a has a higher probability of hitting the special symbol than the first special symbol low probability determination table 117a, and more specifically, the first special symbol high probability determination table 116a. 116a has a winning probability per special figure set to 1/30, and the first special symbol low probability determination table 117a has a winning probability per special figure set to 1/300. In other words, the first special symbol high probability determination table 116a is set to have a 10 times higher probability of winning per special symbol than the first special symbol low probability determination table 117a.

  Similarly to the first special symbol success / failure lottery unit 119a, the second special symbol success / failure lottery unit 119b is triggered by the fact that a game ball has won the second start winning award port 37b (the detection signal from the start winning port detection sensor 43b is the main signal). The second special symbol success / failure determination random number obtaining unit 112b that obtains (latches) one special symbol success / failure random number generated by the special symbol success / failure random number generation unit 111 (at the timing input to the control processing unit 11). Then, refer to the second special symbol high probability determination table 116b or the second special symbol low probability determination table 117b to determine whether or not the random number acquired by the second special symbol appropriateness determination random number acquisition unit 112b is per special symbol. If the special symbol is changing when the second special symbol success / failure determination unit 113b and the second special symbol appropriateness determination random number acquisition unit 112b acquire random numbers, the acquisition is performed. Random number up to four as holding ball random number according to the special symbol and a (in other words, four to the upper limit is a predetermined number) second holding ball random number memory unit 115b for special symbol to be stored.

  Here, the second special symbol high probability determination table 116b has a higher probability of hitting the special symbol than the second special symbol low probability determination table 117b, and more specifically, the second special symbol high probability determination table 116b. In 116b, the winning probability per special figure is set to 1/30, and in the second special symbol low probability determination table 117b, the winning probability per special figure is set to 1/300. That is, the second special symbol high probability determination table 116b is set to have a 10 times higher probability of winning per special symbol than the second special symbol low probability determination table 117b.

  The first special symbol success / failure lottery unit 119a refers to the first special symbol low probability determination table 117a to perform a lottery regarding the special symbol's success / failure, and the second special symbol success / failure lottery unit 119b determines the second special symbol low probability determination unit 119b. The gaming state in which the lottery related to whether or not the special symbol is determined with reference to the table 117b corresponds to the “special symbol normal gaming state” of the present invention, and the first special symbol determination lottery unit 119a performs the first special symbol high probability determination table. The gaming state in which a lottery related to whether or not a special symbol is made with reference to 116a, and a lottery related to whether or not a special symbol is made with reference to the second special symbol high-probability determination table 116b is performed by the second special symbol success / failure lottery unit 119b. This corresponds to the “probability fluctuation state” of the present invention.

  In the following description, for the sake of convenience, the first special symbol success / failure lottery section 119a refers to the first special symbol low probability determination table 117a to perform a lottery regarding the success or failure of the special symbol, and the second special symbol success / failure lottery section 119b. A game state in which a lottery for determining whether a special symbol is successful or not with reference to the second special symbol low probability determination table 117b is simply referred to as “special symbol low probability”, and the first special symbol success / failure lottery unit 119a The special symbol high probability determination table 116a is referred to perform a lottery regarding the special symbol success / failure, and the second special symbol high probability determination table 119b refers to the second special symbol high probability determination table 116b to determine whether the special symbol is successful or not. The gaming state where the game is performed is simply referred to as “special figure high accuracy”.

  Further, in the present embodiment, when the reserved sphere random numbers are stored in both the first special symbol reserved sphere random number storage unit 115a and the second special symbol reserved sphere random number storage unit 115b, the second special symbol use A determination is made as to whether or not the reserved ball random number stored in the reserved ball random number storage unit 115b is preferentially read and wins, and control is performed so that the game proceeds according to the determination. . In other words, the game based on the game ball winning in the second start winning port 37b by the special symbol lottery processing unit 110 has priority over the game based on the game ball winning in the first start winning port 37a. Processing is taking place.

  Next, the special symbol type determination processing unit 120 will be described. Whereas the special symbol lottery processing unit 110 described above determines whether or not a special symbol is won, the special symbol type determination processing unit 120 is for determining the type of special symbol. is there. In other words, in the present embodiment, determination of jackpot / losing regarding a special symbol is performed by the special symbol lottery processing unit 110, but the content of the jackpot (type, number of actual rounds, number of electric support) is determined by the special symbol type determination processing unit 120. The configuration is determined. Details of the above jackpot contents will be described later.

  As shown in FIG. 6, the special symbol type determination processing unit 120 sets the value of the loop counter within a predetermined range (0 to 0 in this embodiment) based on an interrupt signal periodically input (for example, every 2 milliseconds). The special symbol type determining random number generator 121 that generates software random numbers by updating the random number one by one in the range up to 199) and the fact that the game ball has won the first start winning opening 37a, The first special symbol type lottery section 129a for determining the type and the second special symbol type lottery for determining the type of the special symbol by lottery when the game ball has won the second start winning opening 37b Part 129b. That is, in the present embodiment, the determination of the type of special symbol is made when triggered by winning the first start winning opening 37a, and when made when triggered by winning the second starting winning opening 37b. There is one.

  The first special symbol type lottery unit 129a is triggered by a game ball winning in the first start winning port 37a (at the timing when the detection signal from the start winning port detection sensor 43a is input to the main control processing unit 11). The first special symbol type determining random number acquiring unit 122a that acquires (latches) one special symbol type determining random number generated by the special symbol type determining random number generating unit 121, and the first special symbol type determining random number A first special symbol type determining unit 123a that determines a special symbol type from a random number acquired by the acquiring unit 122a with reference to the first special symbol type determining table 125a, and a first special symbol type determining random number acquiring unit 122a. First special symbol type that stores up to 4 random numbers (in other words, up to the upper limit of 4 which is a predetermined number) when special symbols are changing when random numbers are acquired And a titration, the random number storage unit 124a.

  As shown in FIG. 7, the first special symbol type determination table 125a has a table configuration in which a special symbol type determination random number and a special symbol type are associated in advance. Specifically, a total of 31 special symbols including 22 types of 14R specific short-lived symbols 1 to 22 and 9 types of 14R normal short-lived symbols 1 to 9 are stored in the first special symbol type determination table 125a. A special symbol type determining random number 0 to 199 is associated with special symbols excluding some of these 31 types of special symbols. Since the special symbol type determining random value range assigned to each special symbol has a different table configuration, the probability that each special symbol is selected by the first special symbol type determining unit 123a is different.

  More specifically, among the 31 types of special symbols stored in the first special symbol type determination table 125a, those having a special symbol type determination random number value of 0 to 14 are referred to as “14R specified short-lived symbols”. 1 ”is associated,“ 14R specified short time symbol 2 ”for those with random numbers from 15 to 19, and“ 14R specific short time symbol for those with random numbers of 20 to 33 ”. “10” is for the random number value of 34 to 51, and “14R specific short time symbol 11” is ... (on the way, explanation is omitted) ..., the random number value is 180 to 188 “14R normal time short symbol 8” is associated with “14R normal time short symbol 9”, and “14R normal time short symbol 9” is associated with the random number value of 189 to 199.

  As is apparent from FIG. 7, the total number of random numbers associated with “14R specific short time symbol 1” is 15 out of 200 special symbol type determining random numbers. The probability that “design 1” is selected is 15/200 × 100 = 7.5%. The selection probabilities of other special symbols are obtained in the same manner, and the values are as described in FIG. In FIG. 7, for a special symbol to which a special symbol type determining random number value is not assigned, such as “14R specified short-lived symbol 3”, the first special symbol type determination table 125a is referred to. Will not be selected.

  Similarly to the first special symbol type lottery unit 129a, the second special symbol type lottery unit 129b is triggered by the fact that a game ball has won the second starting prize port 37b (a detection signal from the starting winning port detection sensor 43b). Is acquired at the timing of the input to the main control processing unit 11), and a random number for determining the second special symbol type is acquired (latched), one random number for determining the special symbol type generated by the random number generator for determining the special symbol type 121. 122b and a second special symbol type determining unit 123b that determines the type of the special symbol with reference to the second special symbol type determining table 125b from the random number acquired by the second special symbol type determining random number acquiring unit 122b. When the special symbol is changing when the second special symbol type determination random number acquiring unit 122b acquires the random number, the acquired random number is limited to a maximum of four (in other words, the predetermined number That up to four upper) and a second special symbol types determination random number storage unit 124b for storing.

  As shown in FIG. 8, the second special symbol type determination table 125b has a table configuration in which a special symbol type determination random number and a special symbol type are associated in advance. Compared with the second special symbol type determination table 125b and the first special symbol type determination table 125a, the special symbol types assigned to each special symbol range although the special symbol types are the same. Is different. Therefore, for example, “14R specified short time symbol 1” has a selection probability of 7.5% when referring to the first special symbol type determination table 125a, but refers to the second special symbol type determination table 125b. In such a case, the selection probability is 4.0%. In addition, “14R specific short time symbol 3” is not selected when referring to the first special symbol type determination table 125a, but when referring to the second special symbol type determination table 125b, Selection is made with a probability of 66.0%.

  Next, the normal symbol lottery processing unit 170 will be described. As shown in FIG. 17, the normal symbol lottery processing unit 170 is a lottery related to a normal symbol triggered by the passing of the game ball through the normal symbol random number generating unit 171 for generating a random number and the through chucker 21. And a normal symbol success / failure lottery section 177 for determining the success / failure. The random number generator 171 for determining whether or not the normal symbol is appropriate generates fewer random numbers than the random number generator 111 for determining whether or not the special symbol is appropriate, but the configuration for generating random numbers is the same. Further, the normal symbol success / failure lottery unit 177 is triggered by the passing of the game ball through the through chucker 21 (at the timing when the detection signal from the through chucker detection sensor 46 is input to the main control processing unit 11). The normal symbol success / failure determination random number acquisition unit 172 that acquires (latches) one random number for normal symbol success / failure determination generated by the determination random number generation unit 171, and the random number acquired by the normal symbol success / failure determination random number acquisition unit 172 The normal symbol is changing when the normal symbol success / failure determination unit 173 that determines whether or not it is a normal symbol and the normal symbol success / failure determination random number acquisition unit 172 acquires a random number. In addition, the reserved symbol random number storage unit 174 for normal symbols that stores the obtained random numbers as the reserved ball random numbers for the normal symbols up to an upper limit of four, and a determination table that is won per common symbol That the probability is low normal symbol low probability determination table 176, the probability of winning per Hiroshi view than the normal symbol low probability determination table 176 and a high normal symbol high probability determination table 175.

  Here, the normal symbol high probability determination table 175 has a higher probability of hitting the normal symbol than the normal symbol low probability determination table 176, and more specifically, the normal symbol high probability determination table 175 is per symbol. In the normal symbol low probability determination table 176, the winning probability per ordinary drawing is set to 1/120. That is, the normal symbol high probability determination table 175 is set to have a much higher probability of winning per regular symbol than the normal symbol low probability determination table 176. When a lottery is made with reference to the normal symbol high probability determination table 175, in most cases, the winning is per ordinary drawing.

  Note that the gaming state in which the normal symbol determination lottery unit 177 refers to the normal symbol low probability determination table 176 to perform the lottery related to the normal symbol corresponds to the “general symbol normal gaming state” of the present invention, and the normal symbol determination lottery unit. A gaming state in which a lottery 177 performs a lottery related to a normal symbol with reference to the normal symbol high probability determination table 175 corresponds to the “time-short gaming state” of the present invention.

  In the following description, for the sake of convenience, the game state in which the normal symbol success / failure lottery unit 177 refers to the normal symbol low probability determination table 176 to perform the lottery related to the normal symbol is simply referred to as “general symbol low probability”. The game state in which the normal symbol winning / not determining lottery section 177 refers to the normal symbol high probability determination table 175 and performs the lottery related to the normal symbol is simply referred to as “ordinary symbol time reduction”.

  In addition, the electric tulip operation control unit 180 controls the solenoid of the electric tulip 49 to open and close based on a command indicating that the normal symbol lottery processing unit 170 has won a lottery. The electric tulip operation control unit 180 controls the electric tulip 49 to be opened twice with an opening time of 2.9 seconds for each ordinary figure during the normal time. The electric tulip 49 is controlled to be opened once with an opening time of 0.2 seconds with respect to one ordinary map. Therefore, during the normal time, as described above, every time the normal symbol lottery processing unit 170 performs a lottery, the normal tuple wins almost every time the normal symbol is drawn, and the electric tulip 49 is released 2.9 seconds x 2 times by the win. Therefore, the player can win a game ball in the electric tulip 49. Therefore, during normal times, the game can be played with almost no game balls.

  Next, in the pachinko machine P according to the present embodiment, four game states of “normal mode”, “time reduction mode”, “inside accuracy mode”, and “probability change mode” are set in advance. The “normal mode” is made up of a gaming state of special figure low probability and normal figure low probability. Further, the “short time mode” is composed of a gaming state with a low probability of special drawing and a short time of normal drawing. In addition, the “inside accuracy mode” is composed of a gaming state with a special figure high probability and a normal figure low probability. Further, the “probability change mode” is made up of a gaming state with a special figure high-precision and a normal figure time reduction. The “inside accuracy mode” is a gaming state in which the special figure high certainty figure low certainty is indistinguishable on the surface, ie, “latency certainty change” although it is internally highly accurate.

  In the present embodiment, when the type of the special symbol described above is determined, the jackpot type, the actual number of rounds, and the number of times of power support (the number of short times) are determined from the special symbol and each of the above modes. ing. This will be described in detail below with reference to FIGS. 9 and 10. 9 is referred to in order to determine the jackpot pattern corresponding to the special symbol type determined by the first special symbol type determining unit 123a, and FIG. 10 is the second special symbol type determining unit 123b. Is referred to in order to determine a jackpot pattern corresponding to the type of special symbol determined. 9 and 10, the special symbol type displayed in white characters on the black background indicates that the special symbol type is not selected in that diagram. That is, in FIGS. 7 and 8, the selection probabilities of 0% are displayed in black and white characters in FIGS.

  Here, in FIG. 9 and FIG. 10, the display positions of the internal accuracy mode and the accuracy variation mode are reversed. In order to emphasize that, the fields of these two modes are displayed in black and white characters.

As shown in FIG. 9 and FIG. 10, the 31 types of special symbols are respectively associated in advance with jackpot patterns that define the jackpot type, the number of real rounds (jackpot game type), and the number of electric support.
Here, the “big hit type” is either “normal hit” that makes the game state related to the special symbol after the big hit game specially low or “probable hit” that makes the special figure highly accurate. It is determined. In the case of a normal hit, the subsequent game state is not likely to win the next special figure, so it is not easy to win the next special figure, but in the case of a probable change, the subsequent game state will be highly accurate in the special figure, so immediately. There is a high probability of winning the next special figure.

  In addition, the “number of real rounds” defines how many times the number of rounds with a ball is executed during the jackpot game (that is, the number of winning balls that can be obtained by the player in the jackpot game). In the present embodiment, as will be described in detail later, there are four types of rounds with a play-out, 5 rounds, 8 rounds, 10 rounds, and 14 rounds. 9 and 10, “R” means the number of rounds.

  The “number of electric support” is the number of games that can be played while being supported by the electric tulip 49. More specifically, the special symbol lottery processing unit is used when the game state is short in normal time. 110 is the number of times that a lottery can be performed according to 110 (the number of games), and corresponds to the “number of times reduced” in the present invention. In the present embodiment, there are four types of power support times: 10 times (Na = 10 times), 20 times (Nb = 20 times), 30 times, and 10000 times (Nx = 10000 times). .

  Here, the electric support 10000 times is a very large value compared to the other times. And in this embodiment, since the winning probability at the time of special figure low probability is 1/300 and the winning probability at the time of special figure high probability is 1/30, while playing a game 10,000 times, Almost definitely winning per special map. In other words, the number of games until winning the next special figure will never exceed 10,000. Therefore, it can be said that the fact that the number of times of electric support is given 10,000 times is equivalent to the fact that the normal drawing time shortens until the next special drawing is won. Then, when the number of electric support is determined to be 10,000, it is determined that the number of special balls will be extended with almost no game balls. A pattern in which the jackpot type is a probable hit and the power support count is set to 10,000 is hereinafter referred to as a “probable infinite time-short pattern”.

  In this way, the jackpot pattern can be any one of the jackpot types of normal hit or probability change, the actual number of rounds of 5R, 8R, 10R, or 14R, or any of 10, 20, 30, or 100,000 times. The number of times of power support is configured with the specified contents. From the combinations of these elements, the jackpot pattern can be set to 2 types (big hit type) × 4 types (number of actual rounds) × 4 types (number of electric support) = 32 types. A specific pattern excluding some of the types is adopted as the jackpot pattern. In the following description, unless otherwise specified, the value of the number of electric support is preliminarily stated here that the game state is the normal mode.

  Of these jackpot patterns, when the jackpot pattern in the normal mode is grouped by the number of real rounds (the number of prize balls that can be obtained by the player in the jackpot game), the group of five times (Na times) with the smallest number of real rounds ( The first jackpot group) is associated with “14R normal time short symbol 9” and the pattern No. 31 and a pattern No. which is associated with “14R specified short time symbol 21” and which defines the probability variation and the contents of 10 electric supports. 21 and a pattern No. which is associated with “14R normal time shorted symbol 8” and the contents of normal hit and power support 20 times are defined. 30 and a pattern No. which is associated with “14R specified short-lived symbol 19” and which defines the probability variation and the contents of power support 20 times. 19 is included. Of the jackpot patterns, the pattern No. 31 (14R normal time short symbol 9) is a jackpot game (normal 5R, power support 10 times) is the first jackpot game of the present invention, pattern no. 19 (14R specific short-time symbol 19) is a jackpot game (5R per probability change, 20 times of electric support), the second jackpot game of the present invention, pattern No. 21 (14R specific short-time symbol 21) is a jackpot game (5R per probability change, 10 times of electric support), the third jackpot game of the present invention, pattern no. A jackpot game with 30 (14R normal time short symbol 8) (normally 5R, 20 times of electric support) corresponds to the fourth jackpot game of the present invention.

  Further, the group having the number of rounds of 5 times is associated with “14R normal time shortened symbol 7” and the pattern No. 29, pattern No. 29, which is associated with “14R specified short-time symbol 17”, and which defines the probability variation and the contents of power support 30 times. 17, “14R specific short time symbol 18”, “14R specific short time symbol 20”, and “14R specific short time symbol 22” associated with “14R specific short time symbol 22”, respectively (pattern Nos. 18, 20, and 22). And are included.

  On the other hand, a group having 8 actual rounds (Nb times) (corresponding to the second jackpot group of the present invention) is associated with “14R normal time short symbol 6” and 20 times per normal hit and power support. Pattern No. in which the contents of 28, pattern No. 28, which is associated with “14R specified short-lived symbol 15” and which defines the probability variation and the content of 20 electric support. 15 and the pattern No. 5 associated with “14R normal time shortened symbol 5” and the contents of the normal hit and the power support 30 times are defined. 27, pattern No. 27, which is associated with “14R specified short-lived symbol 13”, and the contents of the probability variation and the power support 30 times are defined. 13, and “14R specific short time symbol 14” and “14R specific short time symbol 16” are associated with probability variation infinite short time patterns (pattern Nos. 14 and 16), respectively.

  However, as is apparent from FIGS. 9 and 10, this group of eight actual rounds (second jackpot group) does not include a pattern of 10 electric support times. Therefore, when the jackpot game has 8 actual rounds, the power support count of 20 times or more after the jackpot game, that is, 20, 30, or 10,000 times is always given.

  In addition, a group with 10 actual rounds is associated with “14R normal time short symbol 4”, and pattern No. 26, pattern No. 26, which is associated with “14R specified short-time symbol 11”, and the contents of probability variation and power support 30 times are defined. 11, and a probability variation infinitely short time pattern (pattern No. 12) associated with “14R specific short time symbol 12” is further included.

  However, as is apparent from FIGS. 9 and 10, this group of 10 rounds does not include patterns of 10 times and 20 times of electric support. Therefore, when the jackpot game has 10 actual rounds, the power support count of 30 times or 10,000 times is always given after the jackpot game.

  In addition, the group having the number of rounds of 14 is associated with “14R normal time short symbol 3” and the pattern No. 25, a pattern No. 2 that is associated with “14R normal time shorted symbol 2” and the contents of normal hit and power support 20 times are defined. 24, pattern No. 24, which is associated with “14R normal time shorted symbol 1” and the contents of normal hit and power support 30 times are defined. 23, pattern No. 23, which is associated with “14R specified short-lived symbol 9”, and the contents of the probability variation and the power support 10 times are defined. 9 and a pattern No. which is associated with “14R specified short-time symbol 8” and the contents of the probability variation and the power support 20 times are defined. 8 and a pattern No. that is associated with “14R specified short time symbol 7” and the contents of the probability variation and the power support 30 times are defined. 7 is included. Furthermore, the group having 14 actual rounds includes “14R specific short time symbol 1”, “14R specific short time symbol 2”, “14R specific short time symbol 3”, “14R specific short time symbol 4”, “ 14R specific short time symbol 5 ”,“ 14R specific short time symbol 6 ”, and“ 14R specific short time symbol 10 ”are associated with probability variation infinite short time patterns (pattern Nos. 1 to 6, 10), respectively. Yes.

  Thus, when the number of real rounds is 5, the number of electric support is 10, 20, or 30.10000, but when the number of real rounds is 8, the number of electric support is 5 The number of electrification support times that can be selected at the time of the operation is excluded, which is the minimum of 10, 30, 10000, and when the actual round number is 10, the number of electrical support times is 8 The number of electrification supportable times that can be selected at the time of the operation is excluded, which is the smallest number of times of 30,10000. Therefore, in this embodiment, the greater the number of real rounds in the jackpot game, the higher the possibility of increasing the number of times of electric support.

  In addition, here, referring to FIG. 7, looking at the probability of probability variation according to the number of electric support, when the number of real rounds is 5R (first big hit group), the number of electric support is 10 times. Pattern No. 21 (14R specified short-lived symbol 21, third jackpot game) and pattern No. Comparing 31 (14R normal time short symbol 9, first jackpot game), the selection probabilities are the same at 5.5%. Therefore, if the number of electric support is 10 after the big round game with 5R real round, the special symbol types are “14R specific short symbol 21” and “14R normal short symbol 9”. The case is 1: 1, that is, the probability of probability variation and normal probability are halved.

  On the other hand, when the number of real rounds is 5R (first jackpot group), the pattern No. 19 (14R specific short-time symbol 19, second jackpot game) and pattern No. 30 (14R normal short-time symbol 8, fourth jackpot game), the selection probabilities are 9% and 4.5%, respectively. No. 19 is No. Compared to 30, the selection probability is high. Therefore, if the number of electric supporters is 20 after a big hit game with 5R real round, the special symbol types are “14R specific short symbol 19” and “14R normal short symbol 8”. The case is 2: 1, that is, the probability of probability variation is twice as high as the probability of normal variation.

  Furthermore, when the number of real rounds is 5R, the pattern No. 17 (14R specified short time symbol 17) and pattern no. 29 (14R normal time short symbol 7), the selection probabilities are 9% and 4.5%, respectively. No. 19 is No. Compared to 30, the selection probability is high. Therefore, when the number of electric support is 20 after a big hit game with a 5R real round, the types of special symbols are “14R specific short symbol 19” and “14R normal short symbol 9”. The case is 3: 1, that is, the probability per probability change is three times higher than the normal probability.

  Thus, in the present embodiment, when the number of rounds is substantially the same, the selection probability is weighted in advance so that the probability of probability change increases as the number of power support increases.

  In addition, looking at the relationship between the number of real rounds and the probability of being probable with reference to FIG. 7, the pattern No. 17-No. 22 (14R specific short-lived symbols 17-22, first group system probable big hit game) are respectively selected 12%, 0.5%, 9%, 0.5%, 5.5%,. 5%. Therefore, the pattern No. 17-No. The probability that any one of 22 is selected is 12 + 0.5 + 9 + 0.5 + 5.5 + 0.5 = 28% when the above probabilities are added together. On the other hand, the pattern No. 29-No. The probability of selecting 31 (14R normal short-lived symbols 7-9, first group normal jackpot game) is 4%, 4.5%, and 5.5%, respectively. Therefore, the pattern No. 29-No. The probability that any one of 31 is selected is 4 + 4.5 + 5.5 = 14% when the above probabilities are added together. From this, it is understood that when the number of real rounds is 5, the probability per probability change is twice (28% / 14% = 2 times) higher than the possibility per normal.

  On the other hand, among the patterns having the actual number of rounds of 8 (second jackpot group), pattern No. 13-No. The probabilities that 16 (14R specified short-lived symbols 13 to 16 and second group system probable big hit games) are selected are 10.5%, 0.5%, 9%, and 0.5%, respectively. Therefore, the pattern No. 13-No. The probability that any one of 16 is selected is 10.5 + 0.5 + 9 + 0.5 = 20.5% when the above probabilities are added together. On the other hand, the pattern No. 27-No. The probability that 28 (14R normal short-lived symbols 5-6, second group normal jackpot game) is selected is 3.5% and 4.5%, respectively. Therefore, the pattern No. 27-No. The probability that any one of 28 is selected is 3.5 + 4.5 = 8% when the above probabilities are added together. From this, when the number of real rounds is 8, the probability per probability change is about 2.5 times (20.5% / 8% = about 2.5 times) higher than the possibility per normal variation. You can see that

  Furthermore, among the patterns having 10 actual rounds, the pattern No. 11-No. The probability that 12 (14R specified short-time symbols 11 to 12) is selected is 9% and 0.5%, respectively. Therefore, the pattern No. 11-No. The probability that any one of 12 is selected is 9 + 0.5 = 9.5% when the above probabilities are added together. On the other hand, the pattern No. The probability that 26 (14R normal time short symbol 4) is selected is 3%. From this, when the number of real rounds is 10, the probability per probability change is about 3.2 times (9.5% / 3% = 3.2 times) higher than the possibility per normal variation. I understand that

  Here, when the number of real rounds is 5, the case of 8 times, and the case of 10 times, the probability per probability variation is compared with the probability per normal case. In the present embodiment, the number of rounds is about 2.5 times, and in the case of 10 times, the number of rounds is about 3.2 times. Therefore, in this embodiment, the selection probability is increased in advance so that the probability of probability change increases as the number of real rounds increases. It means that weighting is done.

  Thus, in this embodiment, the mechanism is such that the more likely the player is, the more likely it is to win.

  Furthermore, when the probability that the number of real rounds is 5, 8, and 10 is calculated with reference to FIG. 17-22, and pattern no. When the selection probabilities 29 to 31 are totaled, 28% + 14% = 42%, and the probability that a pattern with 8 actual rounds is selected is the pattern No. 13 to 16 and pattern no. The total selection probabilities of 27 to 28 are 20.5% + 8% = 28.5%, and the probability that a pattern with 10 actual rounds is selected is the pattern No. 11-12, and pattern no. The total of the 26 selection probabilities is 9.5% + 3% = 12.5%. Therefore, the probability that the number of real rounds is 5 is the highest, and the probability that it is 10 is the lowest.

  From the above description, in the present embodiment, it is possible to make a prediction as to whether or not the special figure is a probable hit based on the actual number of rounds (the number of winning balls that can be acquired in the jackpot game) and the number of electric support. As will be described in detail later, a common background image is displayed on the effect display device 34 so that it is not possible to distinguish between a normal hit and a probable hit. Therefore, in order for a player to predict the type per special figure, the player must rely on the actual number of rounds and the number of electric support.

  For example, the probability that the number of real rounds will be 10 times is lower than the probability of 5 times and 8 times, so the number of real rounds will not be 10 times. If the number of real rounds in such a jackpot game is 10, the player increases his expectation that the probability of winning a special figure related to the winning is very high. Even if the actual number of rounds is 5 or 8, the possibility of a probable change is higher when the number of electric support is 20 or 30 than when the number of electric support is 10. The player can play a game while expecting a probable hit.

  In the present embodiment, the number of substantial rounds is set to 14 times in addition to 5 times, 8 times, 10 times, and when the number of substantial rounds is 14, the first special symbol type is determined. In the table 125a (FIG. 7), the probability of probability variation is always obtained, and in the second special symbol type determination table 125b (FIG. 8), the selection probability is weighted so as to be a probability variation of 75%. In the second special symbol type determination table 125b, selection probabilities are assigned so that the number of actual rounds is always 14. Therefore, when the second special symbol type determination table 125b is referred to, that is, when the game ball wins the special symbol type determination table 125a when the game ball is won in the second start winning opening 37b. It is advantageous to the player compared with the case of referring.

  Next, the actual number of rounds will be described in detail with reference to FIGS. First, the jackpot game of the present embodiment is configured to continuously perform a round game in which the attacker device 41 opens and closes a predetermined number of times. In one round game, either the attacker device 41 opens after the round game is started, and a predetermined number of game balls are awarded to the exposed big prize opening 42, or a predetermined time has elapsed since the start of the round game. When the end condition (round end condition) is satisfied, the process ends. In this embodiment, the round game is always performed 14 times (rounds) regardless of which of 31 kinds of special symbols is selected. Of the 14 round games, the player acquires a prize ball. The number of round games that can be played, that is, the number of round games with a game is different depending on the type of special symbol. The jackpot game control unit 160 controls the operation of the attacker device 14 and provides a jackpot game (a plurality of types of jackpot games) of the number of rounds according to the type of special symbol.

  The contents of the jackpot game according to the special symbol type (opening / closing pattern of the attacker device 41) will be described below. The jackpot game in this embodiment is configured by combining round games of any pattern of “◯”, “X”, “Special 1”, “Special 2”, and “Special 3” for 14 times.

  In the round game of “○”, the attacker device 41 is released once, the opening time is set to a maximum of 30 seconds, and the round end condition is that nine game balls win the big winning opening 42, or The content is set to indicate that 30 seconds have passed since the round game was started. In this round game of “◯”, the attacker device 41 is opened for a long time, and a game ball can be awarded to the big prize opening 42, so that the player can obtain a prize ball. That is, the round game with “◯” is a round game with a game.

  In the round game of “X”, the attacker device 41 is released once, the open time is set to a maximum of 0.2 seconds, and the round end condition is that nine game balls win the big winning opening 42. , Or the content that is set that either 2 seconds have passed since the round game was started. In this round game of “X”, it is difficult to win a game ball in the big winning opening 42 because the time when the attacker device 41 is open is very short. Therefore, the player cannot obtain a prize ball in the round game of “X”. Therefore, the round game with “×” is a round game without a game.

  As shown in FIG. 12, in the round game of “special 1”, the attacker device 41 is released five times, and the opening time from the first to the fourth time (● mark) is set to a maximum of 0.2 seconds. The opening time of (◎) is set to a maximum of 28 seconds, and the round end condition is that nine game balls win the big prize opening 42 or 30 seconds have passed since the start of the round game. The content is set to indicate that either one has been established. In this special round game, the attacker device 41 can be opened for a long time and a game ball can be awarded to the big prize opening 42, so that the player can obtain a prize ball. That is, the special round game is a round game with a game. Note that the contents of the “special 2” and “special 3” round games are the same as the “special 1”, and thus the description thereof is omitted.

  For example, the jackpot game corresponding to “14R specified short time symbol 1” is a content in which all 14 round games have an opening / closing pattern of “◯” as shown in FIG. Therefore, when this “14R specific time short symbol 1” is selected, all 14 rounds are round games with a game. In other words, the actual number of rounds of “14R specified short time symbol 1” is 14 times.

  In addition, in the jackpot game corresponding to “14R specified short-time symbol 20”, the round game from 1 to 5 rounds is an open / close pattern of “○”, and the round game from 6 to 14 rounds is “X” open / close It becomes a pattern. Therefore, when this “14R specific time short symbol 20” is selected, the game is a round game with a ball up to 1st to 5th rounds, but is a round game without a ball up to 6th to 14th rounds. That is, the actual number of rounds of “14R specified short time symbol 20” is five.

  In the present embodiment, special jackpot game contents including any of “special 1”, “special 2”, and “special 3” are also prepared. For example, in the jackpot game corresponding to “14R specified short-lived symbol 13”, the round game from 1 to 5 rounds becomes an opening / closing pattern of “○”, the round game of 6 rounds becomes an opening / closing pattern of “special 1”, Round games from the 7th to the 8th round become “open / close” patterns, and round games from the 9th to the 14th rounds become the “×” open / close patterns. Therefore, rounds 1 to 8 are round games with balls, and rounds 9 to 14 are round games without balls. That is, the actual number of rounds is eight.

  However, when this “14R specified short-lived symbol 13” is selected, when the sixth round game is started, as shown in FIG. The opening operation is repeated four times. The player sees this action and assumes that the current jackpot game has 5 rounds. If such an assumption is made, the attacker device 41 is suddenly released for 28 seconds, so that the player is greatly excited that the number of real rounds has increased. In this way, “14R specified short-lived symbol 13” is promoted to 8 times while assuming that 8 round games with balls are supposed to be provided, but there are only 5 round games with balls. The contents can be produced as if they were.

  In this way, in this embodiment, since the number of round games (substantial number of rounds) that can be obtained out of 14 rounds is set to be different, it is possible to provide a jackpot game rich in variations.

  Next, a process for determining the special symbol variation time will be described. As shown in FIG. 13, the special symbol variation pattern command determination unit 130 includes a special symbol variation pattern random number generation unit 131 for generating a variation pattern random number for use in determining a variation pattern command related to a special symbol, A first special symbol variation pattern lottery unit 130a for determining a variation pattern (PT) command related to a special symbol based on the winning of a game ball in the start winning port 37a, and a game ball in the second start winning port 37b And a second special symbol variation pattern lottery unit 130b for determining a variation pattern (PT) command based on winning.

  The special symbol variation pattern random number generator 131 updates the value of the loop counter one by one within a predetermined range (from 0 to 9) based on an interrupt signal periodically input (for example, every 2 milliseconds). Generate software random numbers.

  The first special symbol variation pattern lottery unit 130a includes the random numbers for the special symbol variation pattern generated by the special symbol variation pattern random number generation unit 131 when a game ball is won in the first start winning opening 37a. From the first special symbol variation pattern random number acquisition unit 132a for acquiring one random number from the random number acquired by the first special symbol variation pattern random number acquisition unit 132a, with reference to the special symbol common variation pattern command table 134 Up to four random numbers acquired by the first special symbol variation pattern determining unit 135a for determining a variation pattern command related to the special symbol and the first special symbol variation pattern random number acquiring unit 132a when the special symbol is changing And a first special symbol variation pattern random number storage unit 133a for storing. The first special symbol variation pattern lottery unit 130a, when one game ball wins the first start winning slot 37a, similarly to the first special symbol success / failure lottery unit 119a, for one special symbol variation pattern. Get a random number.

  Similarly to the first special symbol variation pattern lottery unit 130a, the second special symbol variation pattern lottery unit 130b also receives a special symbol variation pattern random number generation unit 131 when the game ball is won in the second start winning slot 37b. From the random numbers acquired by the second special symbol variation pattern random number acquisition unit 132b for acquiring one random number from the random numbers for the special symbol variation pattern generated by the second special symbol variation pattern random number acquisition unit 132b, A second special symbol variation pattern determining unit 135b that determines a variation pattern command related to a special symbol with reference to the special symbol common variation pattern command table 134, and a second special symbol variation pattern random number when the special symbol is varying A second special symbol variation pattern random number storage unit 133b that stores up to four random numbers acquired by the acquisition unit 132b. It is. The second special symbol variation pattern lottery unit 130b, when one game ball wins the second start winning opening 37b, similarly to the second special symbol success / failure lottery unit 119b, for one special symbol variation pattern. Get a random number.

  The special symbol common variation pattern command table 134 is a table commonly used by both the first special symbol variation pattern lottery unit 130a and the second special symbol variation pattern lottery unit 130b, as shown in FIG. Fluctuation pattern table A (low accuracy) 134a, variation pattern table B (short time) 134b, variation pattern table C (high accuracy) 134c, variation pattern table D (latency probability) 134d, variation pattern table E (time accuracy) 134e, variation A total of seven tables, a pattern table F (node) 134f and a fluctuation pattern table G (hour lath) 134g, are provided. These tables further include a plurality of small tables. For example, as shown in FIG. 15, the variation pattern table A (low probability) 134 a includes three small tables: a hit table 134 a-1, a hold table for a hold 1 to 3, and a hold table for a hold 4 134 a-3. Has a table.

  The winning table 134a-1 is a small table that is referred to when a special symbol winning lottery unit 119a, 119b wins a special symbol, and the hold table 1 to 3 for the lost table 134a-2 is a special symbol winning lottery It is a small table that is referred to when the number of reserved ball random numbers stored in the special symbol reserved ball random number storage units 115a and 115b is 1 to 3, which is lost by lottery by the units 119a and 119b. The hold 4 miss table 134a-3 is a lottery by the special symbol winning / losing lottery sections 119a and 119b, and the number of reserved ball random numbers stored in the special symbol hold ball random number storing sections 115a and 115b is four. This is a small table referred to in the case of (upper limit).

  Each of the small tables 134 a-1, 2, 3 has a special pattern variation pattern random number and a special symbol variation pattern No. Are configured in advance. Therefore, when the random numbers for the special symbol variation pattern are determined, the variation pattern No. corresponding to the variation pattern random number is referred to by referring to the respective small tables. (Variation pattern command related to special symbol) is automatically determined, and the variation pattern No. The special symbol variation time corresponding to is determined.

  The variation time of special symbols stored in each small table will be described. First, the variation time from 30 seconds to 120 seconds is stored in the hit table 134a-1. The suspension table 134a-2 for the holdings 1 to 3 stores a variation time from 10 seconds to 120 seconds, but includes a relatively short variation time compared to the hit table 134a-1. In the hold 4 loss table 134a-3, the fluctuation time from 2 seconds to 45 seconds is stored. When comparing the hold table 1 for the hold 1-3 134 a-2 and the hold table for the hold 4 134 a-3, the hold table for the hold 4 134 a-3 is relative to the hold table for the hold 1-3-134 a-2. A short variation time is stored.

  In the present embodiment, all the variation pattern No. A jackpot command is composed of 1 to 10, and a change pattern No. selectable at the time of losing is shown. 11 to 30, the variation pattern No. to be reached 15-No. 20, and no. 28-No. 30 (see FIG. 21) constitutes a reach lose command, and other variation patterns No. A normal lose command is configured.

  Although a detailed description is omitted, each of the variation pattern tables B to G is similarly provided with a plurality of small tables, and each small table has a unique variation pattern No. corresponding to the variation pattern table. It becomes the composition of. Therefore, the feature of the effect displayed on the effect display device 34 differs depending on which of the change pattern tables A to G referred to at the start of the game.

  Here, in the present embodiment, which of the variation pattern tables A to G is to be referred to is determined in advance according to the type of special symbol and the number of games after the jackpot game. This will be described below with reference to FIG. FIG. 16 shows which of the variation pattern tables A to G is selected for the number of games after the big hit game from the first time to the 30th time and after the 31st time, depending on the type of special symbol. In the figure, “A” to “G” indicate the types of variation pattern tables.

  For example, when the type of special symbol when winning per special symbol is “14R specified short-lived symbol 13”, the variation pattern table E (timely) from the first game to the ninth game after the jackpot game ends 134e is referenced, and in the 10th game, the variation pattern table F (node) 134f is referenced, and from the 11th game to the 19th game, the variation pattern table E (timeline) 134e is referenced, and the 20th game Is referred to the variation pattern table F (node) 134f, the variation pattern table E (hourly) 134e is referred from the 21st game to the 29th game, and the variation pattern table G (hour lath) in the 30th game. 134g is referred to, and in the 31st and subsequent games, the variation pattern table D (latency) 134d is referred to in advance. .

  The variation pattern table A (low probability) 134a is referred to when the gaming state is in the normal mode, and the variation pattern table B (short time) 134b is referred to when the gaming state is in the short time mode, and the variation pattern table C ( 134c is referred to when the gaming state is in the probability variation mode, the variation pattern table D (latency probability) 134d is referred to when the gaming state is in the probability mode, and the variation pattern table E (time certainty) 134e is The game state is referred to when the probability change mode.

  The variation pattern table F (node) 134f is referred to only when the number of games is 10th or 20th. The variation pattern table G (hour lath) 134g is referred to only when the number of games is 10th, 20th, or 30th. By presetting the number of games to which the variation pattern tables F and G are referenced and the number of times of electric support are the same, it is possible to perform an effect that may end the number of times of electric support. Although not shown, the variation pattern table A (low probability) 134a is set to be referred to in the initial state after power-on or when the RAM is cleared.

  Next, as shown in FIG. 18, the normal symbol variation pattern command determination unit 190 generates a normal symbol variation pattern random number generator 191 that generates a normal symbol variation pattern random number for use in determining a normal symbol variation pattern command. And a normal symbol variation pattern lottery section 196 for determining a variation pattern (PT) command related to symbols.

  The normal symbol variation pattern lottery unit 196 obtains one random number from the random numbers for the normal symbol variation pattern generated by the normal symbol variation pattern random number generator 191 when the game ball passes through the through chucker 21. Based on the random numbers acquired by the normal symbol variation pattern random number acquisition unit 192 and the normal symbol variation pattern random number acquisition unit 192 to be acquired, a variation pattern command related to the normal symbol is determined with reference to the normal symbol variation pattern command table 194. A normal symbol variation pattern determination unit 195 and a normal symbol variation pattern random number storage unit 193 that stores up to four random numbers acquired by the normal symbol variation pattern random number acquisition unit 192 when the normal symbol is changing. Configured. When one game ball passes through the through chucker 21, the normal symbol variation pattern command determination unit 190 acquires one random number for the normal symbol variation pattern.

  The normal symbol variation pattern random number generator 191 updates the value of the loop counter one by one within a predetermined range (for example, 0 to 4) based on an interrupt signal periodically input (for example, every 2 milliseconds). The software random number is generated.

  As shown in FIG. 19, the normal symbol variation pattern command table 194 includes two common symbol variation table A (194-1) and a short ordinary symbol variation table B (194-2). A figure variation table is stored. Each table includes a random number for normal symbol variation pattern and a normal symbol variation pattern No. Are previously associated with each other. Therefore, when the random number for the normal symbol variation pattern is determined, the variation pattern No. corresponding to the random number for variation pattern is referred to by referring to the respective tables. (Variation pattern command related to normal symbols) is automatically determined, and the variation pattern No. The variation time of the normal symbol corresponding to is determined.

  Here, in the present embodiment, with reference to the general symbol variation table A (194-1), the normal symbol variation time is 30 seconds regardless of the random number value for any normal symbol variation pattern. Referring to B (194-2), the normal symbol variation time is 0.6 seconds for any value of the random number for the normal symbol variation pattern. The usual figure fluctuation table A is referred to when the gaming state is the normal mode and the in-probability mode, and the usual figure fluctuation table B is referred to when the gaming state is the time reduction mode and the probability variation mode.

  As described above, since the variation time of the normal symbol is different depending on the gaming state, in this embodiment, for example, in the short time mode and the probability variation mode where the winning probability of the normal symbol is high, the normal symbol is The phenomenon that the electric tulip 49 opens and closes after changing for 0.6 seconds repeatedly occurs. On the other hand, in the normal mode and the certainty mode, the variation time of the normal symbol is as long as 30 seconds and the winning probability of the normal symbol is low, so the electric tulip 49 is not easily released.

  The main control processing unit 11 configured as described above has a special symbol variation pattern determined by the first special symbol variation pattern lottery unit 130a at the start of a game that is triggered by winning the first start winning opening 37a. When the command is transmitted to the effect control processing unit 12a and the lottery by the first special symbol success / failure lottery unit 119a is won, the command related to the special symbol type determined by the first special symbol type lottery unit 129a is also displayed in the effect control process. To the unit 12a. Similarly, the main control processing unit 11 produces a special symbol variation pattern command determined by the second special symbol variation pattern lottery unit 130b at the start of a game that is triggered by winning the second start winning opening 37b. A command related to the special symbol type determined by the second special symbol type lottery unit 129b is also sent to the effect control processing unit 12a when the lottery is won by the second special symbol winning lottery unit 119b. Sending.

  Further, when the game ball passes through the through chucker 21, the normal symbol change pattern lottery unit 196 determines the normal symbol change pattern command and the command related to the lottery result of the normal symbol success / failure lottery unit 177. 12f.

  Here, the game command transmitted from the main control processing unit 11 to the effect control processing unit 12a includes a command related to a special symbol type and a special symbol variation pattern command, and a special symbol. Although there are both those that are configured without the command related to the special symbol type, although the variation pattern command is included, in the following description, these gaming commands are collectively referred to as “game commands”.

  Next, the contents of this game command will be described. The game command is composed of either “No.?” Or “No.?+? Symbol”. Among the game commands, “No.?” Indicates a variation pattern command related to the special symbol determined by the first special symbol variation pattern lottery unit 130a or the second special symbol variation pattern lottery unit 130b. "" Indicates a command related to the special symbol type determined by the first special symbol type lottery unit 129a or the second special symbol type lottery unit 129b.

  For example, when the fluctuation pattern table 134a is referred to, as shown in FIG. 1-No. 30 is determined, but the variation pattern No. 1-No. Since No. 10 refers to the hit table (134a-1), the commands “No. 1” to “No. 10” are jackpot commands. 11-No. 30 is referring to the hold table for hold 1 to 3 (134a-2) or the hold table for hold 4 (134a-3), so each of the commands “No. 11” to “No. 30” is lost. It is a command. Further, as shown in FIG. 7 and the like, commands related to the types of special symbols are composed of 31 types of commands in total such as “14R specific short-time symbols 1-22” and “14R normal time short-lived symbols 1-9”. .

  Therefore, if the game command includes any information of the variation patterns “No. 1” to “No. 10”, the game command is a jackpot command, and if the command “? It can be seen whether the game command is per probability change or normal, how many rounds are actual, and how many times the electric support is performed. If the game command includes any information of the variation patterns “No. 11” to “No. 30”, it is understood that the game command is a lose command. The same applies to the game command when the variation pattern tables B to G are referred to. Although a detailed description is omitted, in this embodiment, a code that indicates which one of the variation pattern tables A to G is referred to when the game command is analyzed is described in the game command.

  Next, a sub control processing unit that receives various commands (commands) from the main control processing unit 11 and controls various devices will be described. An effect control processing unit 12a, a special symbol display control unit 12b, a lamp control processing unit 12c, a payout control processing unit 12e, and a normal symbol display control unit 12f constituting the sub control processing unit are provided on the back surface of the game board 3 with support members and the like. Is a device that controls the effect display device 34, the speaker 20, and other effect devices (such as LED devices) in accordance with the processing information generated by the main control processing unit 11.

  As shown in FIG. 20, the effect control processing unit 12 a displays, as a processing unit, an effect mode determining unit 210 for determining an effect mode and the effect mode determined by the effect mode determining unit 210 on the effect display device 34. Each time the game ball is won and the reserved ball random number is stored in the start winning opening 37a, b and the effect display control unit (effect display control means) 220 for controlling the game, the reserved ball display device 34a is stored in a predetermined manner. A holding ball display control unit 230 that performs holding ball display. In addition, the effect control processing unit 12a serves as a storage unit, which includes effect tables A to G in which a plurality of types of effect patterns (effect modes) are stored, and a plurality of background images in which background images to be displayed on the effect display device 34 are stored. Tables 262 to 265 are provided.

  The effect mode determination unit 210 determines the effect pattern to be used this time while referring to the effect tables A to G stored in the effect mode storage unit 260 based on the game command related to the game at the start of the game. Here, the effect table A (low probability) 261a is referred to when a game command based on the variation pattern table A (low probability) 134a is input, and similarly, the effect table B (short time) 261b is the variation pattern table. When a game command based on B (short time) 134b is input, the effect table C (high accuracy) 261c is displayed when the game command based on the variation pattern table C (high accuracy) 134c is input. When the game command based on the variation pattern table D (latency probability) 134d is input to the effect table 261d, the effect table E (time accuracy) 261e is the game command based on the variation pattern table E (time accuracy) 134e. When input, the effect table F (node) 261f is based on the variation pattern table F (node) 134f. If the command is input, effect table G (h Las) 261 g, if the game command based on the variation pattern table G (h Las) 134 g is input, is adapted to be reference.

  FIG. 21 shows the configuration of the effect table A (low probability) 261a among these effect tables A to G. As shown in FIG. 21, the effect table A (low probability) 261a has a configuration in which an effect pattern is associated with a game command. For example, a game command No. In “1+” symbol, “normal reach A1” and “normal reach A2” having a variation time of 30 seconds are stored as corresponding production patterns. 13, “no reach B” with a variation time of 10 seconds is stored as the corresponding effect pattern.

  For example, when “No. 15” is sent as the game command to the effect control processing unit 12a, the effect mode determining unit 210 performs the effect pattern “normal reach A1” corresponding to the game command “No. 15”. Alternatively, one effect pattern is determined by lottery from “Normal reach A2.” The production tables B to G are different in the content of the production pattern, but the configuration thereof is the same as that of the production table A, and therefore illustration and description thereof are omitted.

  Furthermore, the effect display control unit 220 not only displays the effect pattern determined by the effect mode determination unit 210 but also performs control to display the background image of the effect display device 34. The background images are stored in the normal background image table 262, the latent / temporal common background image table 263, the probability variation confirmed background image table 264, and the electric support continuation / end background image table 265, respectively. The background image is displayed on the effect display device 34 by referring to any background image table according to the game state.

  Specifically, the effect display control unit 220, when a game command based on the variation pattern table A (low probability) 134a and the variation pattern table D (latency probability) 134d is input, the normal / latent background image table 262. The background image stored in is displayed on the effect display device 34. Further, when a game command based on the variation pattern table B (temporal time) 134b and the variation pattern table E (time accuracy) 134e is input, the effect display control unit 220 is stored in the electric support middle background image table 263. The displayed background image is displayed on the effect display device 34. Similarly, when the game command based on the variation pattern table C (high probability) 134c is input, the effect display control unit 220 displays the background image stored in the probability change confirmed background image table 264 as the effect display device 34. When the game command based on the variation pattern table F (node) 134f is input, the background image stored in the electric support continued background image table 265 is displayed on the effect display device 34, and the variation pattern table is displayed. When a game command based on G (hour lath) 134 g is input, the background image stored in the electric support end background image table 266 is displayed on the effect display device 34.

  Thus, since the same background image stored in the normal / hidden background image table 262 is displayed on the effect display device 34 in the normal mode and the indeterminate mode, the player can play the gaming state from the background image. It is difficult to identify whether the current mode is the normal mode or the certainty mode. For example, as shown in FIG. 7, when the types of special symbols are “14R specific short-lived symbol 13” and “14R normal short-lived symbol 5”, the jackpot type is the former, and the latter is a normal one. Although there is a difference, there is a common fact that the number of real rounds is 8 times and the number of electric support is 30 times. Therefore, as shown in FIG. 16, the background image displayed on the effect display device 34 after the jackpot game is from the first to the thirty times (except for the tenth, twentieth and thirty times). The background image stored in H.263, the tenth and twentieth times are both background images stored in the electric support continued background image table 265, and the thirty times are both stored in the electric support end background image table 266. The images are used as the background images stored in the normal / latent background image table 262 for the 31st and subsequent times so that the player cannot predict what the current gaming state is even when viewing the background images. ing.

  Therefore, the player predicts whether the current special figure per probability variation or normal per unit is based on the number of electric support and the number of real rounds in the jackpot game. For example, when the number of real rounds is 8 or 10, and the number of electric support is 30, the player increases his expectation that this special figure may be a probable hit, Can enjoy. In other words, in the present embodiment, while performing display control so as to make it difficult to predict what the gaming state is from the background image displayed on the effect display device 34, the current number of power support and the actual number of rounds are used. The game provides the enjoyment that allows the player to predict whether the gaming state is the in-probability mode (whether the jackpot is a probable hit). In other words, the pachinko machine according to the present embodiment suggests the latent probability change based on the number of electric supports and the actual number of rounds.

  Of course, in the present embodiment, in order not to know which special symbol type has been won, it is possible to display a jackpot on the effect display device 34, and how many times the electric support is performed from the beginning. Needless to say, they are not displayed.

  Returning to FIG. 4, the special symbol display control unit 12 b causes the special symbol display device 17 to stop after changing the special symbol for a predetermined time based on the game command output from the main control processing unit 11. Is displayed. In addition, the normal symbol display control unit 12f outputs the normal symbol to the normal symbol display measure 22 for a predetermined time according to the lottery result determination command and the normal symbol variation pattern command output from the main control processing unit 11. After variably displaying only, it is stopped and displayed in a predetermined manner. The basic symbol display control unit 12f has substantially the same basic configuration of display control, although the symbol to be displayed is different from the display control by the special symbol display control unit 12b described above. The lamp control processing unit 12c receives commands from the main control processing unit 11 and controls lighting of various lamps and electrical decorations.

  The payout control processing unit 12e receives a signal from the CR unit and controls the prize ball paying device 14 so as to lend out a game ball to the player. In addition, the payout control processing unit 12e receives a payout command from the main control processing unit 11 to receive a predetermined number of balls. The prize ball payout device 14 is controlled so as to pay out the prize ball to the player. The prize ball payout device 14 includes a sprocket (not shown) in which notches are formed for holding game balls one by one, and a motor (not shown) for rotating the sprocket. By controlling the rotation of the motor, the required number of prize balls can be paid out. Specifically, when the start winning opening detection sensors 43a and 43b, the general winning opening detection sensor 44, the large winning opening detection sensor 45, etc. detect the passage of the game ball, the winning ball payout device 14 passes through the main control processing section 11. The game ball is paid out based on the received command.

  The firing control processing unit 13 is a device that controls the operation of the launching device 9 according to the rotation amount of the handle 7. More specifically, control processing is performed such as energizing the launching device 9, stopping energization, or changing the energization current. The launch control processing unit 13 is connected to the payout control processing unit 12e, and a launch stop signal is received when the CR unit is not connected.

  Next, with reference to FIG. 22, a description will be given of the procedure of the game processing relating to the special symbol of the pachinko machine P according to the embodiment of the present invention, which one of the first start winning port 37a and the second starting winning port 37b? Since the processing related to the game is the same even if a game ball wins at the start winning opening, a case where a game ball wins at the first start winning opening 37a will be described below.

  As shown in FIG. 22, the main control processing unit 11 determines whether or not the game ball has won the first start winning opening 37a (step S1). When winning (Yes in step S1), the first special symbol success / failure determination random number acquisition unit 112a acquires a special symbol success / failure determination random number acquisition unit, and the first special symbol type determination random number acquisition unit 122a acquires a special symbol type. A random number for determination is acquired, and the first special symbol variation pattern random number acquisition unit 132a acquires a random number for the special symbol variation pattern (step S2). If the special symbol is fluctuating (Yes in step S3), the special symbol success / failure random number obtained in step S2 is stored in the first special symbol reserved ball random number storage unit 115a and the special symbol type determining random number is first. The special symbol variation random number storage unit 124a stores the special symbol variation pattern (PT) random number in the first special symbol variation pattern random number storage unit 133a (step S4), and returns to the position before step S3. Wait until the game related to the current prize starts.

  On the other hand, when the special symbol is not fluctuating, that is, when the game order has come (No in step S3), the process proceeds to step S5 to perform a special symbol hit determination process. That is, the first special symbol success / failure determination unit 113a determines whether or not the acquired special symbol success / failure determination random number is per special symbol. Next, the process proceeds to step S6, and a special symbol type determination process is performed. Specifically, when the result of the special symbol per-determination process in step S5 is determined to be per special symbol, the first special symbol type determining unit 124a uses the special symbol type determining random number acquired in step S2. Based on this, the type of special symbol for that special figure is determined. That is, referring to FIG. 7, one special symbol out of 31 types of special symbols is determined in step S6.

  By determining the type of the special symbol in this step S6, whether the current special symbol is per probability change or normal, how many real rounds are in the jackpot game, and the jackpot game end It is determined how many times the subsequent electric support is performed. Although not shown, in this embodiment, even if it is determined that the game has been lost in step S5, in step S6, a special symbol type determination process is once performed to determine a command related to the special symbol type. However, when it is determined that the game is lost in step S5, a program is set up so that the command related to the type of the special symbol related to the determination is discarded. Therefore, in the case of a loss in step S5, the game command output to the effect control processing unit 12a does not include a command related to the special symbol type. Of course, in the case of a loss in step S5, the process of step S6 may be jumped.

  Next, a special symbol variation pattern command determination process is performed in step S7. In this special symbol variation pattern command determination process, the first special symbol variation pattern determination unit 135a refers to any one of the variation pattern tables A to G based on the acquired special symbol variation pattern random number. (Variation pattern command) is determined.

  Next, in step S8, effect mode determination processing is performed. In this effect mode determination process, the effect mode determination unit 210 refers to any of the effect tables A to G and determines an effect pattern corresponding to the game command as an effect pattern used for the current game. At this time, the effect display control unit 230 determines a background image to be displayed on the effect display device 34 with reference to any of the background image tables 262 to 265 based on the input game command.

  Next, in step S9, the special symbol change is started, and the effect display control unit 220 displays the effect pattern and the background image determined in step S8 on the effect display device. Next, in step S10, the variation of the special symbol is stopped, and the display of the effect pattern is stopped in synchronization therewith.

  Next, when the stopped special symbol is confirmed with a combination per special symbol (Yes in step S11), the jackpot game control unit 160 uses a predetermined opening / closing pattern (see FIG. 11) according to the type of the special symbol. The attacker device 41 is opened to provide a jackpot game (step S12). Next, in step S13, the game state setting unit 140 sets the game state of the special symbol and the normal symbol in the next game.

Specifically, the game state setting unit 140 sets the game state relating to each game and special symbol to “special figure low probability” from the initial state or the RAM clear state until the first win for each special figure. To do. Also, if the jackpot type specified in the jackpot pattern corresponding to the special symbol is won per special figure and the jackpot type specified in the jackpot pattern is a probable hit, the gaming state setting unit 140 may The game state related to the special symbol from the next to the next winning for each special figure is set to “Special figure high accuracy” for each game. On the other hand, if the bonus winning type is won per special figure and the jackpot type specified in the jackpot pattern corresponding to the special symbol is normal winning, the gaming state setting unit 140 will be able to The game state relating to the special symbol from the next to the next winning for the special figure is set to “Special figure low probability” for each game.

  Further, the game state setting unit 140 sets the game state related to each game and the normal symbol to “normal figure low probability” from the initial state or the RAM clear state until the first win for each special figure. Then, when winning per special figure, the game state setting unit 140 reaches the number of times reduced from the first game after the jackpot game ends, as specified in the jackpot pattern corresponding to the special symbol at the time of winning. Until then, the game state related to the normal symbol is set to “short for normal time” for each game. On the other hand, after a predetermined number of short-time games have been performed, the game state setting unit 140 changes the game state relating to the normal symbol until the next winning for each special figure, for each game. To "".

  When the game state in the next game is set in step S13, the process related to one game is completed. In the case of No in step S11, the game state of the next game is set by proceeding to step S13 without providing the jackpot game. If the answer is No in step S1, the game ends without playing the game.

  As described above, according to the pachinko machine according to the present embodiment, when a player wins a special figure and a jackpot game is provided, the actual number of rounds of the jackpot game is how many. And the information on how many times the electric support was played after the jackpot game, whether the hit per special figure was a probable hit or a normal hit, in other words, the current gaming state is a special figure high accuracy state In other words, it is predicted whether the latent probability is currently changing. Therefore, according to the present embodiment, it is possible to predict a gaming state that has not existed in the past, and there is an effect that the preference is increased. Moreover, unprecedented gameability can be realized, and the player's interest can be attracted.

  In the embodiment described above, the special symbol type determination process is performed by associating in advance all of the jackpot type, the actual number of rounds, and the number of times of power support that define the content of the jackpot game with the special symbol type. If the part 120 determines the type of the special symbol, the content of the jackpot game is determined temporarily from the type of the special symbol, but means for determining the jackpot type by modifying this configuration part ( Hereinafter, it is referred to as jackpot type determining means), means for determining the actual number of rounds (hereinafter referred to as jackpot round number determining means), means for determining the number of electric support times (hereinafter referred to as short time number determining means) Can also be provided.

  In the case of this modification, the jackpot type determination means determines whether the jackpot round number is determined based on the probability shown in FIG. 7 and FIG. The means determines the number of real rounds in the jackpot game with the probability shown in FIG. 7 and FIG. 8 from among 5, 8, 10, and 14 times. 7 and the probability shown in FIG. 8 may be determined from 10, 20, 30, and 10,000 times. At this time, when the number of rounds is 5 times, the number of rounds is 10 times, 20 times, 30 times, or 10000 times, but the number of rounds is 8 times. In this case, the number of time reductions of 10 is not selected, that is, the minimum number of time reductions is set to 20, and when the number of real rounds is 10, the time reduction times of 10 and 20 are not selected. It is preferable to create a time-short count table that is 30 times, and to determine the power support count by referring to the time-short frequency table.

  In this way, even if a part of the configuration of the above embodiment example is modified, when the special winning is won and the jackpot game is provided, information that the number of substantial rounds of the jackpot game is Because it is predicted that the latent probability change is currently based on the number of times of electric support after the jackpot game, it is possible to predict the gaming state that has not existed before, increasing the preference In addition to being able to attract players' interests.

  In the above embodiment example, regardless of the type of the special symbol, the number of round games of the jackpot game is determined to be 14 times, and the number of round games with a ball is different depending on the type of the special symbol. As a result, the actual number of rounds is set to 5, 8, 10 and 14 times, but all round games are set to be played, and the number of all round games of the jackpot game is 5 times. , 8 times, 10 times, and 14 times. That is, the actual number of rounds and the total number of rounds of the jackpot game may be the same.
