The pinball game machine causes the second symbol display means to execute symbol variation by not only the winning of the second opening/closing type operation-start means but also non-opening/closing type second operation-start means. The first and second symbol display means are variable in parallel to each other, an expectation value for a game value that a player can acquire is larger in the second profit state than in the first profit state and, when a so-called latent provability variable state is produced after the termination of the first profit state, the pinball game machine elongates an average variation time in a failure symbol variation by the first symbol display means longer than that during a regular game state.

Description

  The present invention relates to a ball game machine such as a pachinko machine or an arrangement ball machine.

  For example, a recent pachinko machine has two sets of symbol display means and corresponding symbol start means, that is, the first lottery performed on condition that the non-opening / closing type first start means detects a game ball. The first symbol display means for variably displaying the first symbol based on the result of the above, and when the stopped symbol after the variation of the first symbol display means becomes the first specific mode based on winning in the first lottery First profit state generating means for generating a first profit state, and based on the establishment of a predetermined release condition, the game ball is released from a closed state in which entry is impossible or difficult to enter to an open state in which entry is easier. Second opening and closing type starting means, and second symbol display means for variably displaying the second symbol based on the result of the second lottery performed on condition that the second opening and closing type starting means detects a game ball, Based on winning in the second lottery, Second profit state generating means for generating a second profit state when the stop symbol after movement becomes the second specific mode, and generating a special gaming state with a predetermined probability after the end of the first and second profit states A special gaming state generating means, and during the special gaming state, a high probability state in which the winning probability of the first and second lotteries is higher than normal, and the opening time of the second opening / closing type starting means is longer than normal. There are many cases where at least one of the open extended state occurs (for example, Patent Document 1).

  In this type of pachinko machine, for example, the player who is in the second specific mode on the other second symbol display means side is more likely to have the player than the case where the first specific mode is on the first symbol display unit side. While there is a difference in the contents of the first and second profit states so that the expected number of winning balls can be increased, among the special game states that occur after the first and second profit states, the extended extended state (so-called In general, it is difficult to win a game ball in the second opening / closing type starting means except at the time of high base.

  Further, in this type of pachinko machine, the first specific mode is displayed on the first symbol display means side during the normal gaming state (a state of low probability and low base in which neither high probability state nor open extended state occurs). If it becomes, it becomes a latent probability change state with high probability after the end of the first profit state (a so-called high probability / low base state in which only a high probability state occurs between a high probability state and an open extension state), If the first specific display means again enters the first specific display state during the latent probability changing state, both the high probability state and the open extension state occur with high probability after the end of the first profit state (so-called high probability state). Probability / high base state), and a game with a gameability that is extremely advantageous for the player is also known.

JP 2010-110460 A

  In such a pachinko machine, it is necessary to draw at least two wins on the first symbol display means side until it becomes a high probability and high base state advantageous to the player. However, there was a problem that it was difficult to obtain the player's understanding because sufficient prize balls could not be obtained.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a ball game machine with new gameability that can easily be understood by the player.

  The present invention includes a first symbol display means 24a for variably displaying a first symbol based on a result of a first lottery performed on condition that the non-opening / closing first starter 39 detects a game ball, A first profit state generating means 76 for generating a first profit state when the stop symbol after the change of the first symbol display means 24a becomes the first specific mode based on winning in one lottery, and a predetermined release A second open / close starter 27 for opening the game ball from a closed state in which it is impossible or difficult to enter into an open state in which it is easier to enter based on the establishment of the condition; The second symbol display means 24b for variably displaying the second symbol on the basis of the result of the second lottery performed on condition that the means 27 detects the game ball, and the first symbol based on winning in the second lottery. 2 The stop symbol after the change of the symbol display means 24b is the second special feature. A second profit state generating means 76 for generating a second profit state when it becomes a mode, and a special gaming state generation for generating a special gaming state with a predetermined probability after the first profit state and the second profit state are ended. Means 77, and during the special gaming state, a high probability state in which the winning probability of the first lottery and the second lottery is higher than normal, and the opening time of the second open / close-type starting means 27 is normal. At least one of the extended extended state occurs, and after the end of the first profit state, as the special gaming state, a latent probability changing state in which the high probability state occurs and the open extended state does not occur is predetermined. In a ball game machine configured to be generated with probability, when the non-opening / closing type second starting means 40 is provided and not only the second opening / closing type starting means 27 but also the second starting means 40 detects a game ball In However, the second symbol variation is displayed by the second lottery and the second symbol display means 24b, and the other symbol variation is performed during either one of the first or second symbol display means 24a, 24b. The expected value of the game value obtained by the player is larger in the second profit state than in the first profit state, and during the latent probability changing state, the first symbol display means 24a The average symbol variation time in symbol variation that does not become the first specific mode is longer than that in the normal gaming state other than the special gaming state.

  Further, during the latent probability changing state, the average symbol variation time in the symbol variation that does not become the first specific mode by the first symbol display means 24a is the symbol variation that does not become the second specific mode by the second symbol display means 24b. It is desirable to make it longer than the average symbol variation time at.

  In addition, when the second specific mode is caused by the symbol variation by the second symbol display means 24b in the latent probability changing state, the open extended state is generated with a predetermined probability after the second profit state is ended. You may comprise. Further, when the first specific state is caused by the symbol variation by the first symbol display means 24a in the latent probability changing state, the open extended state is not generated after the first profit state is ended. Also good.

  In addition, on the distribution start means 26, the distribution entrance ball mouth 51, the first start means 39, the second start means 40, and the game ball that has entered the distribution entrance ball opening 51 are placed in the first start means. A sorting unit 54 that sorts between the 39 side and the second starting unit 40 side may be provided.

  According to the present invention, since the probability of winning on the second symbol display means 24b side is higher than in the normal gaming state, the player may obtain a lot of gaming value at the time of the second winning from the normal gaming state. There is an advantage that it is easy to obtain an understanding of the player.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 1-17 has illustrated one Embodiment which employ | adopted this invention for the pachinko machine. In FIG. 1, a gaming machine main body 1 is an inner frame that is pivotally attached to a rectangular outer frame 2 and a left and right side of the outer frame 2, for example, a left hinge 3 so as to be openable and detachable around a longitudinal axis. And a frame 4.

  The inner frame 4 is provided with a game board 5 and the like on the upper side, and a launching means 6 and the like on the lower side, respectively, and a glass door 7 covering the front side of the game board 5 on the front side of the inner frame 4 A lower opening / closing door 8 that covers the front side of the launching means 6 and the like under the glass door 7 is pivotally attached to the hinge 9 on the same side as the hinge 3 so as to be opened and closed and detachable. For example, two glass plates are mounted on the glass door 7 in the glass window 10 corresponding to the game area 15 on the front side of the game board 5, and the lower opening / closing door 8 is paid out from a payout means (not shown). An upper plate 11 that stores the supplied game balls and supplies them to the firing means 6, a lower plate 12 that stores excess balls when the upper plate 11 is full, a launch handle 13 that is operated to actuate the launch means 6, etc. Is provided.

  A guide rail 14 for guiding a game ball fired from the launching means 6 is annularly mounted on the game board 5, and a central display unit 16 and a central start winning unit are placed in a game area 15 inside the guide rail 14. 17, a number of game nails (not shown) are arranged in addition to unit parts such as the right start winning unit 18, the big winning unit 19, and the normal winning unit 20. Further, various displays such as an image display means 21, a normal symbol display means 22, a normal reserved number display means 23, a first special symbol display means 24a, a second special symbol display means 24b, etc. on the plurality of unit parts 16-20. In addition to the means, a normal symbol starting means 25, a distribution starting means 26, a second opening / closing type starting means 27, a big winning means 28, a plurality (three in this case) of normal winning means 29, etc. are provided.

  The central display unit 16 constitutes a display frame of the image display means 21 composed of a liquid crystal display means and the like. Corresponding to the image display means 21 is detachably fixed to the front side of the game board 5. The central display unit 16 is in contact with the front side of the game board 5 and substantially surrounds the front mounting plate 33 fixed to the game board 5 by a fixing screw or the like and the internal region 16a corresponding to the image display means 21 and the like. For example, a display frame 34 protruding from the front side of the front mounting plate 33 is provided integrally, for example, and a game ball driven into the upper side of the game area 15 by the launching means 6 is left and right at the top of the display frame 34. It is sorted and flows down either the left-side down flow path 35a on the left side or the right-side down flow path 35b of the right side of the central display unit 16.

  Further, for example, on the display frame 34, other than the display means such as the normal symbol display means 22, the normal reserved number display means 23, the first special symbol display means 24a, the second special symbol display means 24b, etc. A warp entrance 36 into which a game ball flowing down the left flow path 35a can enter is provided at the front lower portion of the image display means 21. The game ball entering the warp entrance 36 is freely rolled in the left-right direction and left-right direction. A central central drop part 37 or a stage 38 for dropping from both the left and right sides is provided.

  The normal symbol display means 22 is for variably displaying the normal symbol, and is composed of, for example, two light emitters (for example, LEDs) corresponding to two types of normal symbols “O” and “X”. On condition that the normal symbol starting means 25 composed of a gate or the like detects the game ball, the two light emitters blink alternately for a predetermined time, and the hit determination random number value acquired when the normal symbol starting means 25 detects the game ball In the state where the “◯” side illuminant corresponding to the hit mode emits light when it matches the predetermined hit determination value, and the “×” side illuminant corresponding to the off mode otherwise The flashing stops when is emitted. When the normal symbol is changed and stopped in a hit state, a normal profit state is generated in which the second opening / closing starter 27 is opened a predetermined number of times for a predetermined time.

  Further, when the normal symbol starting means 25 detects a game ball during the fluctuation display of the normal symbol display means 22 or during the normal profit state, the hit determination random number value acquired at the time of detection detects a predetermined upper limit hold. The number, for example, four, is stored as a limit, and the normal number-of-holds display means 23 made of, for example, the same number of light-emitting bodies as the maximum number of reserved numbers indicates the number of stored random numbers (hereinafter, the number of normal reservations) for the hit determination by the number of light emission. It is displayed to inform the player of the number of normally reserved items at that time.

  The first and second special symbol display means (first and second symbol display means) 24a and 24b are each one or plural, for example, one each of the first and second special symbols (first and second symbols). ) In a variable manner, and the first special symbol display means 24a is based on the fact that the first starting means 39 on the distribution starting means 26 detects a game ball, and The second special symbol display means 24b is based on the fact that either the second starting means 40 on the distribution starting means 26 or the second opening / closing type starting means 27 detects the game ball, respectively. Are displayed for a predetermined period of time, and the jackpot determination random number value obtained when the first starting means 39, the second starting means 40, and the second opening / closing type starting means 27 detect the game ball coincides with a predetermined jackpot determination value. If you do (in the first and second lottery Predetermined jackpot aspect when selected) (first, second specific aspect), so as to respectively stop in a manner off otherwise. If any of the first and second special symbols is changed and then stopped in a big win mode, a special profit state (first and second profit states) in which the big winning means 28 is released according to any of a plurality of types of release patterns, for example, occurs. To do.

  In the present embodiment, the first special symbol display means 24a has two types of jackpot modes, the first and second jackpot modes, and the second special symbol display means 24b has two jackpot modes, the third and fourth jackpot modes. Each is provided (FIG. 5). It should be noted that the first and second special symbols only need to exist in a plurality of types, for example, “0” to “9”, and they are different from each other. It does not have to be discernable.

  Further, when the first and second starting means 39 and 40 and the second opening / closing type starting means 27 detect the game ball during the fluctuation display of the first and second special symbols or during the special profit state, the detection is made. The jackpot determination random number obtained at the time is stored with a predetermined upper limit holding number, for example, 4 each as a limit and, for example, the jackpot for the first and second special symbol display means 24a, 24b on the image display means 21 The number of stored random numbers for determination (hereinafter referred to as first and second special reserved numbers) is displayed, and the player is notified of the first and second special reserved numbers at that time.

  In the present embodiment, the variation of the other symbol can be started during the variation of either one of the first and second special symbol display means 24a and 24b, that is, the first and second special symbol display means 24a and 24b are parallel to each other. However, if one of the first and second special symbol display means 24a, 24b is in a big hit mode and the other symbol variation starts, the other symbol variation is forced. If one of the first and second special symbol display means 24a, 24b is a big hit mode and the special profit state starts when the other is changing, the other Does not stop the measurement after interrupting the measurement of the predetermined fluctuation time, and during the special profit state related to either one of the first and second special symbol display means 24a, 24b, a new symbol variation is caused by the other. Don't start It shall be controlled.

  If one of the first and second special symbol display means 24a, 24b is in a big hit state and the other is changing when the special profit state is started, the other is forced at that time, for example In other words, the display may be controlled so as to stop in a disengaged state and continue the display as it is. Also, even if one of the first and second special symbol display means 24a, 24b starts the variation of the other symbol during the variation that becomes the big hit mode, the other symbol variation result is drawn by lottery as usual. If one of the symbols becomes a jackpot after that decision, during the special profit state, for the other symbol, stop measuring the symbol after measuring the predetermined variation time. You may control.

  In addition, on the image display means 21, the fluctuation display by the first and second effect symbols 30a and 30b is synchronized with the fluctuation display of the first and second special symbols by the first and second special symbol display means 24a and 24b. To be done. Each of the first and second effect symbols 30a and 30b is composed of one or more, for example, three symbols of left, right, and middle, and the first effect symbol 30a is the first effect on the distribution start means 26. Based on the fact that the starting means 39 detects the game ball, the second effect symbol 30b is detected by either the second starting means 40 or the second opening / closing type starting means 27 on the distribution starting means 26. Based on this, the left and right sides start to change according to a predetermined change pattern simultaneously with the start of change of the first and second special symbols, respectively, and finally stop simultaneously with stop of change of the first and second special symbols. It stops in a predetermined order such as middle.

  For the first and second effect symbols 30a and 30b, for example, ten kinds of numeral symbols “0” to “9” are used, and three symbols such as “6, 6 and 6” and “7, 7 and 7” are used. Are all in the same design, the jackpot mode, and those in which at least one design is different are out of mode. Further, the stop symbol after the fluctuation of the first and second effect symbols 30a and 30b is a big hit when the first and second special symbols by the first and second special symbol display means 24a and 24b are stopped in a big hit mode. When the first and second special symbols are stopped in a disengagement mode, any disengagement mode is obtained.

  Further, the selection of the variation pattern of the first and second effect symbols 30a and 30b is performed using a predetermined variation pattern selection table. A plurality of types of variation pattern selection tables are provided, and any one of the plurality of types of variation pattern selection tables is used according to the gaming state. In the present embodiment, as shown in FIG. 6, three types of variation pattern selection tables, which are usually latent and highly accurate, are provided for each of the first and second special symbols (total of six types). For example, the normal variation pattern selection table is used during the normal gaming state, the latent probability variation pattern selection table is used during the latent probability state, and the high probability variation pattern selection table is used during the high probability state. Details of the special game states such as the latent state and the high probability state will be described later.

  In addition, the average symbol variation time (hereinafter referred to as the first average deviation variation time) of the variation pattern, which is a deviation mode for the first effect symbol (and the first special symbol), and the second effect symbol (and the second special symbol). For example, as shown in FIG. 7, the average symbol variation time of the variation pattern that becomes an out-of-phase (hereinafter referred to as the second variation average variation time) differs for each type of variation pattern selection table. That is, in the normal variation pattern selection table, the first outlier average variation time and the second outlier average variation time are both about 15 seconds, and in the highly accurate variation pattern selection table, the first outlier average variation time and the second outlier average. While both the fluctuation times are about 10 seconds, in the latent fluctuation pattern selection table, the first outlier average fluctuation time is about 60 seconds and the second outlier average fluctuation time is about 7 seconds.

  As described above, in the present embodiment, the first deviation average fluctuation time (60 seconds) during the latent state is significantly longer than the first deviation average fluctuation time (15 seconds) during the normal gaming state. The first deviation average fluctuation time (60 seconds) in the latent state is significantly longer than the second deviation average fluctuation time (7 seconds) in the same latent state. In the example of FIG. 7, the second outlier average fluctuation time is shorter in the latent state than in the normal gaming state, but this is not restrictive.

  FIG. 8A shows an example of a first outlier variation pattern selection table (latency) for selecting a variation pattern in the case where the first effect symbol is out of the manner in the latent probability variation pattern selection table. (B) is an example of a second outlier variation pattern selection table (latency) for selecting a variation pattern when the second effect symbol is out of the same manner in the latent probability variation pattern selection table, FIG. c) is a first and second jackpot variation pattern selection table (latency) for selecting a variation pattern in the case where the first and second effect symbols are jackpots among the latent probability variation pattern selection table. An example is shown.

  In the example of FIG. 8, the first deviation average fluctuation time during the latent state is 59.55 seconds (FIG. 8A), and the second average deviation time during the latent state is 7.1 seconds (FIG. 8 (FIG. 8). b)). In addition, the average symbol variation time of the variation pattern which becomes a big hit mode for the first and second effect symbols in the latent state is 77.5 seconds (FIG. 8C).

  In addition to the first and second effect symbols 30a and 30b described above, the image display means 21 is displayed in synchronization with fluctuations in the first and second effect symbols 30a and 30b as shown in FIG. Various effect images such as second effect images 31a and 31b and first and second reserved display images 32a and 32b indicating the first and second special reserved numbers are displayed according to the gaming state.

  The big winning unit 19 is arranged along the guide rail 14 on the lower right side of the game area 15, for example, and is provided with a normal symbol starting means 25, a big winning means 28 and the like. The normal symbol starting means 25 is constituted by a passing gate through which a game ball can pass, and is arranged, for example, in the upper right part of the big winning unit 19, and has a lower right flow path 35b than the game ball flowing down the left flow path 35a. The game balls that have flowed down can pass with an overwhelmingly high probability. The normal symbol change by the normal symbol display means 22 is performed based on the detection of the game ball by the normal symbol starting means 25.

  The big winning means 28 includes a horizontally-long rectangular large winning opening 44 formed along the front surface of the game board 5, a closed state in which the game ball cannot win and an open state in which the winning is easy. The game ball that has flowed down the right flow path 35b than the game ball that has flowed down the left flow path 35a is disposed on the lower left side of the big winning unit 19, for example. It is possible to win with a high probability. The special winning means 28 is opened according to any one of a plurality of types of opening patterns during a special profit state that occurs when any of the first and second special symbols stops in a big hit mode after a change. Yes. When a game ball wins the open big winning means 28, a predetermined number of game balls per payout are paid out as a prize ball.

  In the present embodiment, two types of 15R opening pattern and 2R opening pattern are provided as the opening pattern of the big winning means 28 as shown in FIG. 5, and the stop pattern after the fluctuation of the first special symbol is a big hit mode. In the first special profit state (first profit state) that occurs in the event of becoming, the 2R opening pattern is selected regardless of the type of the big hit mode, and the stop symbol after the fluctuation of the second special symbol is the jackpot type In the 2nd special profit state (2nd profit state) which occurs when it becomes, the 15R release pattern is selected irrespective of the kind of the big hit mode.

  The 15R opening pattern is an operation for closing the special winning means 28 on condition that a predetermined time (for example, 30 seconds) elapses after the opening or a predetermined number (for example, 9) of game balls have won. Set to do round. Further, the 2R release pattern is set so that the operation of releasing the special winning means 28 for 0.2 seconds is performed for two rounds. Since this 2R opening pattern has a short opening time of 0.2 seconds, the possibility that a game ball wins during the opening is very small.

  As described above, in the present embodiment, a large amount of play can be expected in the second special profit state (second profit state) that occurs when the second special symbol becomes a big hit mode, whereas the first special symbol is In the 1st special profit state (1st profit state) which occurs when it becomes the big hit mode, it is almost impossible to expect the appearance.

  From the above, the second special profit state that occurs when the second special symbol becomes a jackpot mode rather than the first special profit state (first profit state) that occurs when the first special symbol becomes a jackpot mode ( It is clear that the expected value of the number of winning balls (game value) that the player can obtain in the second profit state) is larger, and the probability of a big hit mode is the same for the first special symbol and the second special symbol Therefore, it can be said that it is more advantageous for the player to change the second special symbol more than the first special symbol.

  In addition, after the special profit state ends, a special game state composed of, for example, a combination of a high probability state and an open extended state occurs for a predetermined period with a predetermined probability. During the high probability state, by increasing the number of jackpot determination values than in the other low probability states, the probability that the first and second special symbols will be a jackpot mode is higher than the normal probability (for example, 1/380). A high probability (for example, 1/40) is set.

  During the open extended state, the open / close pattern of the second open / close starter 27 is switched from the normal open / close pattern (for example, 0.2 seconds × 1 open) to the extended open / close pattern (for example, 2 seconds × 3 open) ( In addition to that, with respect to the first and second special symbols, the variation times of the first and second special symbol display means 24a and 24b are switched to the shortened variation times shorter than the normal variation times, respectively. The hit probability is from a normal probability (eg, 1/10) to a high probability (eg, 1 / 1.3), the change time is from a normal change time (eg, 27 seconds) to a shortened change time (eg, 2.7 seconds), Each can be switched (FIG. 4). In the following description, the “high base” is defined as being in the open extended state, and the “low base” is defined other than being in the open extended state.

  In the present embodiment, as shown in FIG. 6, as the basic special gaming state, a high probability / low base “latency probability state” (latency probability variation state) and a high probability / high base “high probability state” are selected. A type is assumed to be provided. Of course, the normal gaming state in which no special gaming state has occurred has a low probability and a low base. Note that a low-probability / high-base “time-short state” may be provided.

  Also, in this embodiment, the type of special gaming state that occurs after the end of the special profit state is the time of jackpot change related to the occurrence of the special profit state, that is, for example, the first and second special symbols become a big hit mode. It is determined according to the gaming state at the start and the type of the jackpot mode.

  In the example of FIG. 5, when the first special symbol becomes the first big hit mode, the gaming state at the time of starting the symbol variation is the normal gaming state (low probability / low base) and the latent state (high probability / low base). ) Is a latent state (high probability, low base), and a high probability state (high probability / high base) is a high probability state (high probability / high base). Each is supposed to occur. Further, when the second special symbol becomes the third big hit mode, a highly probable state (high probability / high base) is generated regardless of the gaming state at the time of starting the symbol variation. For the case where the first special symbol is in the second jackpot mode and the case where the second special symbol is in the fourth jackpot mode, the special game state is the same regardless of the game state at the start of the symbol variation, etc. Does not occur.

  Note that the high-accuracy state and the latent state will continue until the next special profit state occurs. For example, the total number of changes in the first and second special symbols before the next special profit state occurs. If the value reaches a predetermined value, the process may be terminated at that time.

  In the example of FIG. 5, the probability that a special gaming state will occur when the first special symbol becomes a jackpot mode, that is, the probability that the first jackpot mode of the first and second jackpot modes is selected is 80%. The probability that a special gaming state will occur when the second special symbol is a jackpot mode, that is, the probability that the third jackpot mode is selected from the third and fourth jackpot modes is 80%.

  The right start winning unit 18 is disposed, for example, at a position sandwiched between the central display unit 16 and the big winning unit 19 and is provided with a second opening / closing type starting means 27. The second open / close-type starting means 27 has a pair of winning openings 46 that open to both the left and right sides, a closed state in which the game balls cannot be won (or difficult to win), and an open state in which winning is easier than that. A pair of left and right opening / closing means 47 that can be switched to and from, for example, disposed above the special winning means 28 and on the left side of the normal symbol starting means 25, to the right of the game ball flowing down the left flow path 35a. A game ball that has flowed down the flow path 35b can win a prize with a higher probability.

  The second opening / closing type starting means 27 is configured to be opened according to any one of a plurality of types of opening / closing patterns during a normal profit state that occurs when the normal symbol is stopped in a hit state after fluctuation. The second open / close starter 27 includes a game ball detector (not shown) that detects a game ball won in the winning opening 46, and the second open / close starter 27 wins a game ball ( Based on the fact that the second open / close starter 27 detects a game ball), the second special symbol display means 24b changes the second special symbol, and a predetermined number of game balls are awarded as winning balls. To be paid out.

  The normal winning unit 20 is arranged along the guide rail 14 on the lower left side of the game area 15, for example. On this normal winning unit 20, a plurality (three in this case) of normal winning means 29 are arranged, for example, in an oblique line along the inner side of the guide rail 14, and have flowed down the right flow path 35b. A game ball that has flowed down the left flow path 35a is more likely to win a prize than a game ball. When a game ball wins the normal winning means 29, a predetermined number of game balls per payout are paid out as a prize ball.

  The central start winning unit 17 is arranged at the lower center of the game area 15, that is, below the central display unit 16 and between the normal winning unit 20 and the big winning unit 19, and is provided with a distribution starting means 26 and the like. ing. As shown in FIGS. 1 and 2, the distribution starting means 26 includes a distribution entrance ball opening 51 that opens upward corresponding to the lower side of the central dropping portion 37 of the stage 38, and a lower side of the distribution entry ball entrance 51. A first pair of left and right first and second start ports 41 and 42 arranged in the first and second start ports 41 and 42 for guiding a game ball that has entered the distribution start ball port 51 to the first start port 41 and the second start port 42, respectively. A distribution movable body (distribution means) 54 that distributes the game balls that have entered the second guide passages 52 and 53 and the distribution entrance entrance 51 to the first and second guide passages 52 and 53, and drives the distribution movable body 54 And a first and second game ball detecting means 56 and 57 for detecting the game balls won in the first and second start ports 41 and 42, respectively.

  The distribution entrance opening 51 branches into a first guide passage 52 on the right side and a second guide passage 53 on the left side on the lower side, and a distribution movable body 54 is arranged at the branched portion. The distribution movable body 54 is supported so as to be swingable around the rotation shaft 54 a in the front-rear direction, and is driven by the distribution drive means 55 so as to communicate the distribution entrance port 51 and the first guide passage 52. (Shown by a solid line in FIG. 2) and a second sorting posture (shown by a one-dot chain line in FIG. 2) that allows the sorting ball entrance 51 and the second guide passage 53 to communicate with each other. The sorting movable body 54 is driven with a constant pattern, for example, or with a different pattern depending on the gaming state or the like.

  For example, a game ball that has entered the distribution entrance 51 during the period from the second distribution posture (shown by a one-dot chain line in FIG. 2) to the first distribution posture (shown by a solid line in FIG. 2) is as follows. As indicated by the solid line arrow in FIG. 2, the distribution movable body 54 is guided to the first guide passage 52 when the distribution movable body 54 reaches the first distribution posture. For example, the distribution movable body 54 changes from the first distribution posture to the second distribution posture. The game balls that have entered the distribution entrance 51 during the period up to the second guidance path 53 when the distribution movable body 54 assumes the second distribution posture as shown by the two-dot chain line arrow in FIG. Guided to the side.

  The first and second guide passages 52 and 53 are bent downward on the side of the sorting movable body 54, and their downstream end portions 52a and 53a and the first and second start ports 41 and 42 are It faces up and down across a gap through which game balls can pass. The first and second start ports 41 and 42 constitute the first and second start means 39 and 40 together with the first and second game ball detecting means 56 and 57. It is formed in a shape and opens upward. Further, a gap through which a game ball can pass is provided between the first start port 41 and the second start port 42.

  Accordingly, the game ball flowing down the first guide passage 52 wins the first start port 41, and the game ball flowing down the second guide passage 53 wins the second start port 42 with a very high probability. The possibility of jumping left or right from the gap above the first and second start ports 41 and 42 is not zero. The game balls that have won the first and second start ports 41 and 42 are guided to the back side of the game board 5 and are detected by the first and second game ball detecting means 56 and 57 at that time.

  In the pachinko machine of the present embodiment, there is a route to enter the entrance entrance 51 from the warp entrance 36 through the stage 38, and so on, so that the left down route 35a is less than the game ball down the right down route 35b. It is assumed that the game ball that has flowed down can enter the entrance entrance 51 with a higher probability.

  FIG. 3 is a block diagram of the control system of the pachinko machine. In FIG. 3, 61 is a main control board, 62 is an effect control board, and each of these control boards 61, 62 collects the central display unit 16 mounted on the game board 5 and a plurality of other game parts from the back side. The board case is detachably mounted at appropriate places on the back side of the gaming machine main body 1 including the inner frame 4 and the game board 5 such as the back side of the back cover.

  The main control board 61 controls the game operation in an integrated manner, and includes a normal symbol processing means 71, a normal symbol display control means 72, a normal profit state generating means 73, and a special symbol processing constituted by a CPU, a ROM, a RAM and the like. Means 74, special symbol display control means 75, special profit state generation means 76, special game state generation means 77, control command transmission means 78 and the like are provided.

  The normal symbol processing means 71 performs processing related to normal symbol variation display. Based on the fact that the normal symbol starting means 25 detects a game ball, it acquires random number information including a hit determination random number value and the random number. The information is stored in the first-in first-out ordinary random number storage means 71a with a predetermined upper limit holding number (for example, four) as a limit, and the normal symbol display means 22 is in a state in which it can be variably displayed and 1 in the ordinary random number storage means 71a. On the condition that at least one piece of random number information is stored (the number of normal holdings is 1 or more), the first hit determination random number value of the queue is extracted from the normal random number storage means 71a, and the hit determination random number value is Make a hit / miss judgment according to whether or not it matches a predetermined hit judgment value, and select the stop symbol and variation time after the normal symbol variation It is configured to.

  In the present embodiment, as shown in FIG. 4, the hit probability (for example, 1 / 1.3) at the time of high base (in the open extended state) is the hit probability (for example, not in the open extended state) at the low base (for example, in the open extended state). It is set to be higher than 1/10), and the variation time at the high base (for example, 2.7 seconds) is set to be shorter than the variation time at the low base (for example, 27 seconds).

  The normal symbol display control means 72 controls the display of the normal symbol display means 22 based on the normal symbol processing by the normal symbol processing means 71. The normal symbol display means 22 is in a state in which the normal symbol display means 22 can be variably displayed and the normal random number storage means. On the condition that one or more random number information is stored in 71a (the number of normal holdings is 1 or more), the normal symbol display means 22 starts to change the normal symbol, and is selected by the normal symbol processing means 71 Based on the elapse of the variation time, the variation of the normal symbol is stopped at the stop symbol selected by the normal symbol processing means 71.

  When the normal symbol processing means 71 obtains a winning determination result, the normal profit state generating means 73 obtains the second open / close-type start when the stop symbol after the fluctuation of the normal symbol display means 22 becomes the winning mode based on the result. The opening / closing means 47 of the means 27 is changed to an open state according to any of a plurality of types of opening / closing patterns.

  In this embodiment, as the opening / closing pattern of the second opening / closing type starting means 27, as shown in FIG. 4, a normal opening / closing pattern (for example, 0.2 seconds × opened once) and a time in an open state than this normal opening / closing pattern. There are two types of extended opening / closing patterns (for example, 2 seconds × 3 times opening) that are set so that the number of times of opening and / or the opening time per opening becomes long. The normal opening / closing pattern is selected at the base time (except during the open extended state), and the extended opening / closing pattern is selected at the high base time (in the open extended state).

  The special symbol processing means 74 performs processing relating to the variable display of the first and second special symbols, and performs first special symbol management processing (FIG. 9) relating to the variable display of the first special symbol. The processing means 81, the 2nd special symbol management processing means 82 etc. which perform the 2nd special symbol management process (FIG. 9) regarding the change display of a 2nd special symbol are provided. These first and second special symbol management processes (FIG. 9) are executed in the order of, for example, the first special symbol management process → the second special symbol management process at the time of timer interruption every predetermined time (here, every 4 ms). And

  FIG. 9 shows a flowchart of the first special symbol management process, and only the difference between the second special symbol management process and the first special symbol management process is shown in parentheses. The same applies to the flowcharts of FIG. Further, as is clear from FIG. 9, the first special symbol management process and the second special symbol management process have exactly the same basic processing procedure, so here the first special symbol management processing means 81 performs the first special symbol management process 81. The symbol management processing will be described, and the second special symbol management processing by the second special symbol management processing means 82 will be referred to as necessary.

  In the first special symbol management process (FIG. 9), first, a first special start port check process is executed (S1). In the first special starting port check process (S1), as shown in FIG. 10, it is first determined whether or not a game ball has been won by the first starting means 39 (S11). If it is determined that there is no winning (S11: No), the first special start port check process ends here. In the case of the second special start opening check process, it is determined in S11 whether or not a game ball has been won in either the second starter 40 or the second open / close starter 27 (S11). Parentheses).

  If it is determined that the first starting means 39 has been won (S11: Yes), it is determined whether or not the first special reserved number has reached the upper limit reserved number (for example, four) (S12). . If it is determined in S12 that the first special hold number has reached the upper limit hold number, the processes in S13 and S14 are skipped, and for example, a first hold addition command corresponding to an overflow is sent to the effect control board 62. It is transmitted (S15), and the first special start port check process ends. In the case of an overflow, the transmission of the first hold addition command (S15) may not be performed.

  When it is determined in S12 that the first special reserved number is less than the upper limit reserved number (for example, 4), 1 is added to the first special reserved number (S13), and the jackpot determination random number and jackpot symbol random number Each value of the variation pattern selection random number is acquired and stored at the tail of the queue on the first special random number storage means 81a (S14). And the 1st reservation addition command corresponding to the 1st special reservation number after addition is transmitted to production control board 62 (S15), and the 1st special start opening check processing is ended.

  Following the first special start port check process (S1), the value of the special profit state flag is determined (S2). Here, the special profit state flag indicates whether or not the special profit state is in effect. For example, “5AH” is set during the special profit state.

  When it is determined that the special profit state flag is 5AH, the processing of S3 to S6 related to the variation of the first special symbol is skipped, and the first special symbol display data is updated (S7). The management process ends. As a result, during the special profit state, the processing relating to the fluctuation of the first and second special symbols is not performed, so that no new fluctuation of the first and second special symbols is started, and the first and second special symbols are not started. If the symbol is already fluctuating, the measurement of the fluctuating time is interrupted until the special profit state ends, and the symbol variation continues without stopping.

  When it is determined that the special profit state flag is not 5AH, that is, when it is not in the special profit state, the value of the first special symbol operation status indicating the situation relating to the variation of the first special symbol is determined (S3), Processing according to the value is executed. In the present embodiment, when the first special symbol operation status is “00H” or “01H” corresponding to “waiting for variation”, the first special symbol variation start process (S4) corresponds to “during variation”. If it is “02H”, the first special symbol changing process (S5) is executed, and if it is “03H” corresponding to “under confirmation”, the first special symbol checking time process (S6) is executed. It has come to be.

  In the first special symbol variation start process (S4) executed when the first special symbol operation status is “00H” or “01H” corresponding to “waiting for variation”, for example, as shown in FIG. It is determined whether or not the first special reserved number is 0 (S21). When it is determined that the first special reserved number is 0, it is determined whether or not the first special symbol operation status is “00H” (waiting for variation) (S41), and the first special symbol is determined. On condition that the operation status is not “00H” (waiting for fluctuation) (S41: No), “00H” is set to the first special symbol operation status (S42) and the second special symbol operation is performed. If the status is 00H (S43: Yes), that is, if the second special reserved number is 0 and the second special symbol is waiting for fluctuation, a customer waiting command is transmitted to the effect control board 62 (S44), The first special symbol variation start process ends.

  On the other hand, if it is determined in S21 that the first special reserved number is not 0, the first special reserved number is decremented by 1 (S22), and the first reserved subtract command is transmitted to the effect control board 62. (S23), random number shift processing (S24) is performed. In this random number shifting process (S24), each random number value stored at the head of the queue on the first special random number storage means 81a is moved to a predetermined variation storage area, and each of the second and subsequent queues in the queue. The random value is shifted to the front of the queue.

  Subsequent to the random number shift process (S24), for example, a jackpot determination process (S25) is executed. In this jackpot determination process (S25), for example, as shown in FIG. 12, the value of the second jackpot determination flag relating to the other second special symbol is determined (S51). Here, the second jackpot determination flag indicates whether or not the second special symbol is changing to become a jackpot mode. If the second special symbol is changing to be a jackpot mode, for example, 5AH is set. It is supposed to be set.

  When it is determined that the second jackpot determination flag is not 5AH, that is, when the second special symbol is not changing to become a jackpot mode, a jackpot determination random number determination process (S52) is executed. In the jackpot determination random number determination process, the jackpot determination / departure determination is performed according to whether or not the jackpot determination random number value among the random number values transferred to the variable storage area in S24 matches a predetermined jackpot determination value. Performed (first (second) lottery). Then, when the jackpot determination result is obtained, 5AH is set in the first jackpot determination flag (S53), and the jackpot determination process ends.

  On the other hand, when it is determined in S51 that the second jackpot determination flag is 5AH, that is, when the second special symbol is changing to be a jackpot mode, the jackpot determination random number determination process (S52) is not executed, For example, 5AH is set in the first special symbol forced-off flag to force the first special symbol to be in the off mode (S54), and the big hit determination process ends.

  Subsequent to the above jackpot determination process (S25), for example, a special stop symbol creation process (S26) is executed. In this special stop symbol creation process (S26), for example, as shown in FIG. 13, the value of the first special symbol forced detachment flag is determined (S61), and it is determined that the first special symbol forced detachment flag is not 5AH. Is set with the first special stop symbol number corresponding to the stop symbol of the first special symbol based on the jackpot symbol random number value or the like (S62). That is, for example, if the determination result by the jackpot determination random number determination process (S52) is a jackpot, the first and second are based on the jackpot symbol random number value among the random number values transferred to the variable storage area in S24. When one of the big hit modes is selected and the determination result by the big hit determination random number determination process (S52) is out of the range, for example, either one or a plurality of types of out-of-band modes are selected by lottery.

  On the other hand, when it is determined in S61 that the first special symbol forced detachment flag is 5AH, a number corresponding to the detachment mode related to forced detachment is set in the first special stop symbol number (S63).

  When the above special stop symbol creation process (S26) ends, for example, a game state transition preparation process (S27) is executed. In this gaming state transition preparation process (S27), for example, as shown in FIG. 14, the value of the first jackpot determination flag is determined (S71), and it is determined that the value of the first jackpot determination flag is 5AH. That is, on the condition that the determination result by the jackpot determination random number determination process (S52) regarding the first special symbol is a jackpot, for example, based on the gaming state transition table as shown in FIG. The information on the special gaming state corresponding to the gaming state at the start of the variation of the first special symbol and the type of the big hit mode selected in S62 is stored in the state transition buffer (S72).

  Therefore, when the gaming state at the time of S72 (at the start of the variation of the first special symbol that becomes a big hit mode) is, for example, a normal gaming state (low probability, low base), for example, the first big hit mode is selected in S62 The information on the latent state (high probability / low base) is stored in the state transition buffer.

  When the process of S72 is executed, the first special symbol becomes a big hit mode and a special profit state is generated, and when the special profit state ends, a special special is made based on information stored in the state transition buffer. A gaming state is started. As described above, in the present embodiment, the special profit state (first and second profit states) is based on the fact that the stop symbol after the fluctuation of the first and second special symbols becomes the jackpot mode (first and second specific modes). ) Is determined in accordance with the gaming state at the start of the first and second special symbol variations that have become a big win mode.

  Subsequent to the above game state transition preparation process (S27), for example, a variation pattern selection process (S28) is executed. In this variation pattern selection process (S28), for example, as shown in FIG. 15, the value of the first special symbol forced detachment flag is determined (S81), and it is determined that the first special symbol forced detachment flag is not 5AH. Is a variation pattern selection table (such as FIG. 6) corresponding to the gaming state at that time, the determination result by the jackpot determination random number determination process (S52), and the variation pattern selection among the random number values transferred to the variation storage area in S24 A variation pattern of the first effect symbol is selected based on a random value or the like, a first variation pattern designation command corresponding to the variation pattern is created and transmitted to the effect control board 62, and the first special symbol operation is also performed. A value corresponding to the variation time of the variation pattern is set as an initial value in the timer (S82).

  On the other hand, if it is determined in S81 that the first special symbol forced removal flag is 5AH, for example, a variation pattern dedicated to forced removal is selected based on the variation pattern selection table corresponding to forced removal, and the forced removal A first variation pattern designation command corresponding to the variation pattern is generated and transmitted to the effect control board 62, and a value corresponding to the variation time of the variation pattern is set as an initial value in the first special symbol operation timer. (S83).

  When the above variation pattern selection process (S28) is completed, a first stop symbol command corresponding to the stop symbol pattern of the first special symbol selected in the special stop symbol creation process (S26) is created (S29), and the effect control is performed. Along with the transmission to the board 62 (S30), the first special symbol operation status is set to “02H” (being changed), the first special symbol change is started (S31), and the first special symbol change start is started. The process ends.

  Next, the first special symbol changing process (S5) executed when the first special symbol operation status is “02H” corresponding to “being changed” will be described. In the first special symbol changing process (S5), for example, as shown in FIG. 16, it is determined whether or not the value of the first special symbol operation timer is 0 (S91).

  If it is determined that the value of the first special symbol operation timer is not 0, the value of the first special symbol operation timer is decremented by 1 (S94), and the value of the first special symbol operation timer is 0. Is determined, that is, when the variation time corresponding to the variation pattern selected in S82 and S83 has elapsed from the start of variation of the first special symbol, the first variation stop command is issued to the effect control board 62. Is transmitted (S92), a value corresponding to a predetermined confirmation time (for example, 500 msec) is set in the first special symbol operation timer as a new initial value, and “03H” (under confirmation) in the first special symbol operation status ) Is set (S93), and the first special symbol variation processing ends.

  Since the first (second) special symbol changing process (FIG. 16) is not executed during the special profit state (see FIG. 9), the first and second special symbols that have already changed at the start of the special profit state. For the symbol, the measurement of the variation time, that is, the subtraction of the first (second) special symbol operation timer is interrupted until the special profit state ends, and the symbol variation continues without stopping.

  Next, the first special symbol confirmation time processing (S6) executed when the first special symbol operation status is “03H” corresponding to “under confirmation” will be described. In the first special symbol confirmation time process (S6), for example, as shown in FIG. 17, it is determined whether or not the value of the first special symbol operation timer is 0 (S101). If it is determined that the value of the first special symbol operation timer is not 0, the value of the first special symbol operation timer is decremented by 1 (S105), and the processing during the first special symbol confirmation time is ended here. .

  On the other hand, if it is determined in S101 that the value of the first special symbol operation timer is 0, that is, if a predetermined confirmation time (for example, 500 msec) has elapsed since the first special symbol has stopped changing, the first special symbol The operation status is set to “01H” (waiting for change) (S102), and based on the first jackpot determination flag, the first special symbol change is a symbol change that becomes a big hit mode, or is in a detachment mode. It is determined whether it is a symbol variation (S103).

  When the value of the first jackpot determination flag is 5AH, that is, when it is determined that the first special symbol variation is a symbol variation that becomes a jackpot mode, “5AH” indicating that the special jackpot flag is in the special profit state. ”Is set, and various flags and counters, such as a first jackpot determination flag, a probability variation flag indicating whether or not a high probability state is in effect, an open / extended state flag indicating whether or not an open / extended state, etc. Is cleared (S104), and if the value of the first jackpot determination flag is not 5AH, that is, if it is determined that the first special symbol variation is a symbol variation that is out of place, the first special symbol compulsory On the condition that the removal flag is not 00H, “00H” is set in the flag (S106 → S107), and the process during the first special symbol confirmation time ends.

  The special symbol display control means 75 controls the display of the first and second special symbol display means 24a and 24b, and based on the special symbol processing by the special symbol processing means 74, the first and second special symbol display means. The start and stop of fluctuations of the first and second special symbols by 24a and 24b are controlled.

  The special profit state generating means (first profit state generating means, second profit state generating means) 76 is in a special profit state, that is, the first and second special profits when the first and second special symbols are in a big hit mode. This is for generating a state (first and second profit states), and a jackpot determination result (S52) regarding the first and second special symbols by the special symbol processing means 74 is obtained, based on that When the first and second special symbols by the first and second special symbol display means 24a and 24b are stopped in the big hit mode, the large one according to either the 15R open pattern or the 2R open pattern depending on the type of the big hit mode The winning means 28 is opened (FIG. 5).

  The special gaming state generating means 77 is for generating a special gaming state advantageous to the player for a predetermined period after the end of the jackpot state, and is a high probability state generating means 77a for generating a high probability state, and an open extended state. And an open / extended state generating unit 77b for generating a high probability state generating unit 77a and / or an open / extended state generating unit 77b based on the contents of the state transition buffer (see S72). For example, one of the two types of special game states shown in FIG. 5 is generated.

  The control command transmitting means 78 is for transmitting a predetermined control command to a sub-control board such as the effect control board 62 by one-way communication to give a control command. For example, regarding the variation of the first and second special symbols, Based on the first and second special symbol management processes by the special symbol processing means 74, the effect control board 62 is used when winning the game ball to the first starting means 39, the second starting means 40 and the second opening / closing type starting means 27. The first and second hold addition commands are transmitted to the first and second special symbols when the first and second special symbols start to change, the first and second hold subtraction commands, the first and second change pattern designation commands, The two stop symbol commands are transmitted to the effect control board 62, and the first and second variation stop commands are transmitted to the effect control board 62 when the first and second special symbols are stopped.

  The effect control board 62 controls various effect means such as the image display means 21, the speaker 91, and the LED 92, and includes an effect control means 93, a special reserved number display control means 94, a design effect control means 95, and the like.

  The effect control means 93 controls each effect means. The image display control means 93a for controlling the image display by the image display means 21, the sound control means 93b for controlling the sound output from the speaker 91, the light emission of the LED 92, and the like. The light emission control means 93c etc. to control are provided.

  The special reserved number display control means 94 controls the display of the first and second special reserved numbers on the image display means 21 via the image display control means 93a. The first starting means 39 and the second starting means 40 are used. When the game ball wins any one of the second opening / closing type starting means 27 and receives either the first or second hold addition command from the main control board 61, the first and second hold addition commands are received. Based on the first and second reserved display images 32a and 32b after the increase, a predetermined position on the display screen 21a of the image display means 21 is displayed on the display screen 21a. Based on receiving the first and second hold subtraction commands from the main control board 61 at the start of the variation of the second special symbol, the number of the first and second hold display images 32a and 32b being displayed is reduced by one. Configured to shift forward That.

  The symbol effect control means 95 controls the effect related to the fluctuation of the first and second special symbols. For example, the symbol effect control means 95 receives the first and second variation pattern designation commands and the first and second stop symbol commands from the main control board 61. After performing the notice effect lottery process for drawing the notice effect to be executed during the fluctuation of the first and second effect symbols, and the stop symbol lottery process for selecting the stop symbol of the first and second effect symbols. Based on the variation pattern designated by the first and second variation pattern designation commands, the first and second effect symbols 30a, 30b are varied on the image display means 21 via the effect control means 93, and by lottery. Based on the selected notice effect scenario, a notice effect such as display of the first and second effect images 31a and 31b is executed in synchronization with the fluctuation of the first and second effect symbols.

  In the pachinko machine of the present embodiment configured as described above, as shown in FIG. 5, the second special state (first profit state) is generated more than the first special profit state that occurs when the first special symbol is a jackpot. Probability that the expected value of the number of winning balls (game value) that the player can obtain is greater in the second special profit state (second profit state) that occurs when the special symbol is in the big hit mode, and the probability that it will be in the big hit mode Is the same for the first special symbol and the second special symbol, it is advantageous for the player to change the second special symbol more than the first special symbol.

  However, at the time of low base (except during the open extended state), the probability that the normal symbol display means 22 will be in a hit state is low, and even if the normal profit state occurs due to the hit state, the second special symbol changes. Since the opening time of the second open / close starter 27 for starting is very short (FIG. 4), the second open / close starter 27 can be turned to the right by aiming at the normal symbol starter 25 and the second openable starter 27. The possibility of winning the starting means 27 is very low. On the other hand, on the sorting start means 26, not only the first start means 39 for starting the change of the first special symbol, but also the second start means 40 for starting the change of the second special symbol is provided. Yes. Therefore, in the pachinko machine according to the present embodiment, at the time of low base, the left-handed left-handed flow is made rather than the right-handed aiming at the normal symbol starting means 25 and the second open / close-type starting means 27 on the right-falling path 35b side. It is more advantageous for the player to aim for winning the first and second starting means 39, 40 from the path 35a side through the sorting entrance 51.

  The player makes a left strike in the normal gaming state (low probability / low base), and the game ball enters the entrance entrance 51 through the left drop path 35a, for example, the warp inlet 36, the stage 38, and the central drop unit 37. When the ball enters the distribution entrance 51 by being guided by a game nail or the like without passing through the stage 38 or the like, the game ball falls onto the distribution movable body 54 operating in a predetermined pattern, The distribution movable body 54 distributes the first guide passage 52 and the second guide passage 53. Then, the game ball that has flowed down to the first guide passage 52 side enters the first start port 41 that constitutes the first start means 39, and the game ball that has flowed down to the second guide passage 53 side forms the second start means 40. 2 Each winning opening 42 is won with a very high probability.

  The game ball won in the first starting port 41 is detected by the first game ball detection means 56 when guided to the back side of the game board 5, and based on this, the first special symbol management processing means 81, the special symbol display The first special symbol is changed by the first special symbol display means 24a under the control of the control means 75 or the like. On the other hand, the game ball won in the second start port 42 is detected by the second game ball detection means 57 when guided to the back side of the game board 5, and based on this, the second special symbol management processing means 82, special The second special symbol is changed by the second special symbol display means 24b under the control of the symbol display control means 75 or the like.

  Note that even if one of the first and second special symbol display means 24a and 24b is changing, the other symbol change can be started, but the first and second special symbol display means 24a and 24b When either one of them is in the big hit mode, the other symbol variation is forcibly removed and either one of the first and second special symbol display means 24a, 24b is selected. If the other is changing when the special profit state is started and the other party is changing, the other does not stop the design after interrupting the measurement of the predetermined change time, Control is performed so that a new symbol change by the other is not started during the special profit state related to one of the first and second special symbol display means 24a, 24b.

  When the stop symbol of the second special symbol display means 24b becomes a big hit state during the normal gaming state (low probability / low base), the second special profit state (second profit state) occurs, and the big winning means 28 is opened in a 15R opening pattern. Therefore, the player can easily obtain a large number of balls by aiming at the big winning means 28 on the right flow down path 35b and switching to the right hand. Further, after the end of the second special profit state (second profit state), for example, a high probability state (high probability / high base) occurs with a probability of 80% (FIG. 5). Accordingly, the player can make a right turn in the special profit state and aim at the normal symbol starting means 25 and the second opening / closing type starting means 27 on the right flow path 35b, thereby making it more advantageous than when the base is low. You can play games.

  On the other hand, when the stop symbol of the first special symbol display means 24a becomes a big hit mode during the normal gaming state (low probability / low base), the first special profit state (first profit state) occurs. In this case, since the big winning means 28 is opened in the 2R opening pattern, even if the player switches to the right-handed position, the player can hardly expect to play. Further, after the end of the first special profit state (first profit state), for example, a latent state (high probability / low base) occurs with a probability of 80% (FIG. 5). During this latent state, the probability that the first and second special symbols will be a big hit mode is higher than in the normal gaming state (high probability state), but it is a low base as in the normal gaming state, so the big hit state After the end of the game, the player will again switch to left-handed.

  By the way, during this latent state, the variation patterns of the first and second effect symbols 30a and 30b are selected using the latent probability variation pattern selection table (FIGS. 7 and 8). As shown, the first deviation average fluctuation time (60 seconds) in the latent state is significantly longer than the first deviation average fluctuation time (15 seconds) in the normal gaming state. Since the second out average fluctuation time (7 seconds) in the state is shorter than the second out average fluctuation time (15 seconds) in the normal gaming state, the first out average fluctuation time in the latent state (60 seconds) is significantly longer than the second outlier average fluctuation time (7 seconds) in the same latent state.

  As a result, during the latent state, the game balls are awarded to the second starting means 40 as compared to the number of fluctuations of the first special symbol and the first effect design 30a due to the winning of the game balls to the first starting means 39. The number of fluctuations of the second special symbol and the second effect symbol 30b is overwhelmingly large. In other words, the probability of a big hit on the second special symbol display means 24b side is higher in the latent probability state than in the normal gaming state, so that the player can acquire a large amount of balls and enter the high probability state. Early transition is realized with high probability.

  As described above, the pachinko machine according to the present embodiment includes the non-opening / closing type second starting means 40 and the case where the second starting means 40 detects not only the second opening / closing type starting means 27 but also the game ball. The second special symbol display means 24b displays the variation of the second special symbol, and during the variation of either one of the first and second special symbol display means 24a, 24b, the other symbol variation can be started. In the second special profit state, the expected value of the game value obtained by the player is larger than in the first special profit state, and during the latent state (high probability / low base), the average symbol by the first special symbol display means 24a By making the fluctuation time longer than that in the normal gaming state, the number of fluctuations of the second special symbol display means 24b is relatively larger than that in the first special symbol display means 24a, thereby comparing with that in the normal gaming state. Second special figure The probability of winning the jackpot on the display means 24b side becomes high. As a result, the player is more likely to obtain a lot of prize balls at the time of the second jackpot winning from the normal gaming state, and there is an advantage that it is easy to obtain the player's understanding.

  As mentioned above, although embodiment of this invention was explained in full detail, this invention is not limited to these embodiment, A various change is possible in the range which does not deviate from the meaning of this invention. For example, a high probability state (high probability / high base) is generated with a predetermined probability when the symbol variation by the first special symbol display means 24a in the latent state becomes a big hit mode (first specific mode). You may comprise.

  The opening pattern of the big winning means 28 in the first special profit state (first profit state) and the opening pattern of the big winning means 28 in the second special profit state (second profit state) are the first special profit state (first What is necessary is just to set so that the expected value of the game value obtained by the player is greater in the second special profit state (second profit state) than in the profit state, and is not limited to the example of FIG.

  Arrangement of the first starter 39, the second starter 40, and the second opening / closing starter 27 on the game area 15 is arbitrary. For example, the second starter 40 is placed not on the sorting starter 26 but on the stage 38. It may be provided.

  The distributing means for distributing the game balls that have entered the distribution entrance 51 to the first starting means 39 side and the second starting means 40 side need not necessarily be movable. Further, when the distributing means is constituted by a movable body, the distributed movable body does not have to be operated by driving of the distribution driving means, for example, the distribution posture is changed by the weight of the game balls to be distributed, etc. There may be. For example, a distribution movable body that can change between a first distribution posture for guiding game balls to the first starter 39 side and a second distribution posture for guiding the game balls to the second starter 40 side is provided, and each game ball is distributed. In addition, the distribution movable body changes from the first distribution posture to the second distribution posture and from the second distribution posture to the first distribution posture by the weight of the game ball, so that the game ball is moved to the first starting means 39 and the second distribution posture. You may comprise so that it may distribute with the starting means 40 alternately. Of course, each time the game ball is guided, the distribution posture of the distribution movable body may be arbitrarily changed instead of alternating.

  The operation pattern of the sorting movable body 54 driven by the sorting driving means 55 may be always constant or may be changed according to the gaming state or the like. In the case where the operation pattern of the sorting movable body 54 is changed according to the gaming state, for example, the second starting means is in the latent state (high probability / low base) compared to the normal gaming state (low probability / low base). The time of the second distribution posture may be extended or increased and / or the time of the first distribution posture may be shortened or decreased so that the probability of distribution to the 40 side increases.

  In the embodiment, after the end of the special profit state (first and second profit states) based on the fact that the stop symbol after the fluctuation of the first and second special symbols becomes a jackpot mode (first and second specific mode) The type of the special gaming state to be generated is determined according to the gaming state at the start of the first and second special symbol variations that have become the jackpot mode, but is not limited to this, for example, jackpot The type of the special gaming state may be determined according to the gaming state at the end of the first and second special symbol variation that has become an aspect.

  In the embodiment, the example in which the first deviation average variation time is longer than that in the normal gaming state is shown during the latent state, but the first time including the variation time in the case of the big hit mode is displayed during the latent state. The first average variation time that is the average variation time of the special symbol may be longer than that in the normal gaming state. Similarly, during the latent state, the first average variation time that is the average variation time of the first special symbol including the variation time when the big hit mode is set is the second average including the variation time when the big hit mode is set. You may make it longer than the 2nd average variation time which is the average variation time of a special symbol.

  The present invention is not limited to pachinko machines and can be similarly implemented in various ball game machines such as an arrangement ball machine and a sparrow ball game machine.
