Description

  The present invention relates to a pachinko gaming machine, and more particularly, to a technique for controlling the operation of an open / close-type special figure starting port.

  In recent years, in the mainstream pachinko machines, the game board has a first special figure start port, an openable second special figure start port, a universal start port (gate), an openable large prize opening, a special indicator, A general-purpose display is provided, and the player operates the launch handle to launch a game ball in a game area where the special-design start opening, the general-purpose start opening, and the big prize opening are arranged.

  When a game ball wins at the special figure starting port, a big hit lottery is performed, and a special symbol is variably displayed on the special figure display. When winning in this jackpot lottery, the special chart big win symbol is stopped and displayed after the change of the special symbol is displayed on the special figure display, and then it shifts to the big hit gaming state, and the big winning opening is over several R (round) Opened and closed.

  When a game ball wins at the general chart start opening (the game ball passes through the gate), a winning lottery is performed, and the normal symbol is variably displayed on the general chart display. When winning in this winning lottery, the symbol per symbol is stopped and displayed after the variation of the normal symbol is displayed on the symbol display, and then the auxiliary game state is entered, and the second special diagram starting port is opened and closed one or more times. The

  In this type of pachinko gaming machine, any one of a plurality of gaming states is alternatively set, and the second special figure start is used as a start opening operation control mode for controlling the operation of the second special figure start opening. One of the two start port operation control modes for controlling the start port winning number expected value at which the game ball wins in the mouth to be different from each other is set according to the game state (see, for example, Patent Documents 1 to 3). ).

  The plurality of game states include a so-called normal state, a short time state, and a probability variation state (probability variation state). Depending on the model, a so-called latent state (latency probability variation state) is further included. The winning probability of the big hit lottery is set to a low probability (for example, 1/300) in the normal state and the short time state, and the winning probability of the big hit lottery is set to a high probability (for example, 1/30) in the probability variation state and the latent state. The As the start port operation control mode, a start port operation control mode is set in which the start port winning number expected value is lowered in the normal state and the latent state, and the start port winning number expected value is increased in the short-time state and the probable state. A start port operation control mode is set.

  Furthermore, in this type of pachinko machine, there are a plurality of winning prize opening / closing patterns for opening and closing the winning prize opening in the big hit game, and the expected number of winning prizes for winning the game balls in the winning prize opening is different from each other. Select and set any one of the winning prize opening / closing patterns of the prize winning opening / closing pattern, and select the winning prize opening / closing pattern with the largest expected winning prize winning number at the highest winning prize opening / closing pattern. There is a model in which the player who wins the jackpot lottery performed by winning the game ball to the second special figure starting point is higher than the player who wins the jackpot lottery performed by winning the game ball.

  In the conventional pachinko gaming machine, there are only two start port operation control modes for controlling the operation of the second special figure start port, and when the game state is the latent state, the same start port winnings expectation as in the normal state is expected. A start port operation control mode is set to lower the value.

  In particular, when winning a big hit lottery by winning a game ball at the 2nd special figure starting gate, winning prize lots by winning a big hit lottery by winning a game ball at the 1st special figure starting port For models with a high selection rate for selecting the winning opening / closing pattern with the maximum expected value, if there are only two start opening operation control modes, the expected winning value for winning the winning prize with respect to the number of special symbol variations When the gaming state is in the latent state, the ratio of selecting the largest winning opening opening / closing pattern is the same as that in the normal state, and the ratio does not change regardless of the staying period in the latent state.

  In other words, when the gaming state is in the latent state, it is easier to win in the big win lottery than in the normal state, but since it is a lottery, the number of times (period) of the special symbol changes until winning in the big hit lottery is very small Sometimes it gets very big. However, this cannot be reflected in the game characteristics, that is, it is not possible to change the ratio of selecting the big prize opening / closing pattern with the largest expected prize winning number expected value with respect to the number of fluctuations of the special symbol. For this reason, the game performance cannot be improved in this respect.

It is characterized by being controlled so as to be different from each other.

  According to a fourth aspect of the present invention, in the third aspect of the present invention, the start opening operation control mode changing means (49b) is configured so that the start opening winning prize expected value is larger than the set start opening operation control mode before the change. It is characterized in that the setting is changed to a high start opening operation control mode.

  According to a fifth aspect of the present invention, in the fourth aspect of the present invention, the jackpot lottery is performed by winning a game ball at the special figure starting port (10, 11a), and the plurality of gaming states are the jackpot lottery. A first gaming state in which the winning probability is set to a predetermined low probability, and different second and third gaming states in which the winning probability is set to be higher than the low probability, 2 gaming state is the predetermined gaming state, and the starting port winning number expected value during execution of the starting port operation control mode in the second gaming state is used as the starting port during execution of the starting port operation control mode in the first gaming state. It is characterized by being higher than the expected number of winnings and lower than the expected starting number of winnings during execution of the starting port operation control mode in the third gaming state.

  According to the pachinko gaming machine of the present invention, any one of the three or more start opening operation control modes is selected and set according to the gaming state, and the predetermined gaming state is set, and the set period from the setting time When the time has elapsed, the game performance can be enhanced by changing the set start port operation control mode to another start port operation control mode.

Big win symbol selection means 43, special figure change time selection means 44, special figure display control means 45, big prize opening control means 46 having a big prize opening opening / closing pattern setting means 46a, winning lottery means 47, universal figure display control means 48, A start port control means 49 having a start port operation control mode setting means 49a and a start port operation control mode changing means 49b, a prefetch determination means 50, and an external output processing means 51 are provided.

  As shown in FIG. 5, the pachinko gaming machine 1 includes a normal state (first gaming state), a short time state, a probability variation 1 state (second gaming state which is a predetermined gaming state), a probability variation 2 state (third game). There are five different game states of (state) and jackpot state, and the game state setting means 41 alternatively sets any one of these five game states.

  The jackpot lottery means 42 performs a jackpot lottery by winning a game ball at the special chart starting ports 10 and 11a. Here, as shown in FIG. 6, the winning probability of the jackpot lottery is predetermined in the normal state and the short time state. The probability is set to about 1/370, which is a low probability, and is set to about 1/50, which is a higher probability than the predetermined low probability in the probability variation 1 state and the probability variation 2 state.

  When the special figure big hit symbol selection means 43 is won by the big hit lottery by the big hit lottery means 42, the normal big hit symbol A, the positive variation 1 big hit symbol B, the first positive variation 2 big hit symbol C1, the second positive variation 2 big hit shown in FIG. One of the four types of special figure jackpot symbols of symbol C2 is selected by lottery. Here, the selection rate of the special figure big hit symbol is the selection rate shown in FIG. 8 (1) when winning in the big hit lottery based on the winning of the game ball to the first special figure starting port 10, and the second special bonus figure is selected. When winning in the big hit lottery based on the winning of the game ball to the start opening 11a, the selection rate shown in FIG.

  The special figure big hit symbol selection means 43 selects one of six kinds of probability variation one big hit symbols B1 to B6 shown in FIG. The selection rates of B1 to B6 are set in advance. For example, the selection rate of each probability variation big hit symbol is set to the same selection rate (about 16%).

  By the way, comparing the selection rates of FIGS. 8 (1) and (2), the selection rate of the normal big hit symbol A is 20% common to (1) and (2), and the selection rate of the first probability variation 2 big hit symbol C1 is also (1) 15% common to (2). On the other hand, the selection rate of the probability variation 1 big hit symbol B is 50% in (1) but 0% in (2), and the selectivity of the second probability variation 2 big hit symbol C2 is (1) Is 15%, whereas in (2) it is 65%. That is, the sum of the selection rates of the probability variation 1 big hit symbol B and the second probability variation 2 big hit symbol C2 in (1) becomes the selection rate of the second probability variation 2 big hit symbol C2 in (2).

  The special figure variation time selection means 44 selects a special symbol variation time (variation pattern) to be displayed on the special figure indicators 18a and 18b based on the winning of the game ball at the special figure start ports 10 and 11a.

  The special chart 7 control means 45 changes the first special symbol to the first special figure display 18a by the winning of the game ball to the first special figure starting port 10 through the control of the first special figure display 18a. When the special figure fluctuation time selected by the special figure fluctuation time selection means 44 has elapsed since the start of fluctuation, and when the winning is won by the big hit lottery by the big hit lottery means 42, after the first special symbol changes The special figure big hit symbol selected by the special figure big hit symbol selecting means 43 is displayed on the first special figure indicator 18a as the stop symbol.

  Further, the special figure display control means 45 gives the second special symbol to the second special figure display 18b by winning the game ball to the second special figure start port 11a through the control of the second special figure display 18b. When the special figure fluctuation time selected by the special figure fluctuation time selection means 44 has elapsed from the start of the fluctuation, the special display fluctuation time is displayed. The special symbol big hit symbol selected by the special symbol big hit symbol selecting means 43 is displayed on the second special symbol display 18b as the stop symbol after the change.

  The big prize opening control means 46 controls the big prize opening device 13 (big prize opening SOL13d) and wins in the big hit lottery by the big hit lottery means 42 and specially displays the first or second special figure display 18a or 18b. When the jackpot symbol is displayed, the game shifts to a jackpot gaming state, and the jackpot 13a is opened and closed over a plurality of Rs ("R" means round). During this time, the game state setting means 41 sets a big hit state.

  As shown in FIG. 7 and FIG. 9, the big prize opening / closing pattern setting means 46a expects the number of big prize opening winnings that a game ball wins in the big prize opening 13a as a big prize opening / closing pattern for opening / closing the big prize opening 13a. A winning opening / closing pattern PA, a winning opening / closing pattern PB, a winning opening / closing pattern PC1 (where PA and PC1 are the same opening / closing pattern), a winning opening / closing pattern PC2, Any one of the four large winning opening / closing patterns including the three different large winning opening / closing patterns is selectively selected and set.

  In this case, as shown in FIG. 7, the special winning opening opening / closing pattern setting means 46a sets and displays a special winning opening opening / closing pattern corresponding to the type of special figure big hit symbol displayed on the special figure indicators 18a, 18b. When the special figure big hit symbol is the normal big hit symbol A, the big winning opening / closing pattern PA is set, and when the special variation big hit symbol B is set, the big winning opening / closing pattern PB is set, and the first positive variation two big hit symbol is set. In the case of C1, the big winning opening / closing pattern PC1 (= PA) is set, and in the case of the second probability variation 2 big hit symbol C2, the big winning opening / closing pattern PC2 is set.

  As shown in FIG. 9, in the winning opening / closing pattern PA, PC1, the winning opening 13a opens and closes over 4 rounds (1R to 4R), and in the winning opening / closing pattern PC2, the winning opening 13a has 16 rounds ( 1R to 16R), and each round of the grand prize opening / closing pattern PA, PC1, PC2 has 30s of opening time of the big prize opening 13a, or the number of game balls won to the big prize opening 13a It ends when it reaches 10. On the other hand, in the prize winning opening / closing pattern PB, the prize winning opening 13a opens and closes over 16 rounds (1R to 16R), and each round of the prize winning opening / closing pattern PB has an opening time of 0. When 1s is reached, the process ends.

  As a result, when a game ball is being fired aiming at the big prize opening 13a during the big hit game, the expected value for the big prize opening number is the big prize opening / closing pattern PB → the big winning opening / closing pattern PA, PC1 → the big winning. In the order of the mouth opening / closing pattern PC2, the game winning ball opening / closing pattern PB hardly gives out game balls, but in the big winning mouth opening / closing pattern PA, PC1, about 500 gaming balls are paid out. In the winning opening / closing pattern PC2, about 2000 game balls can be paid out.

  That is, as shown in FIGS. 7 to 9, when winning a big hit lottery performed by winning a game ball to the second special figure start port 11 a, by winning a game ball to the first special figure start port 10 The expected value of the number of game balls that can be acquired is higher than that in the case of winning the big hit lottery. Specifically, with respect to the selection rate at which the winning opening opening / closing pattern setting means 46a selects the winning opening opening / closing pattern PC2 having the maximum expected winning number at the winning opening, the game ball wins the first special figure starting opening 10. The big hit made by winning the game ball to the second special figure starting port 11a rather than the case of winning the big hit lottery made (15%: selection rate of the second probability variation 2 symbol C2 shown in FIG. 8 (1)) When winning by lottery (65%: selection rate of the second probability variation 2 symbol C2 shown in FIG. 8 (2)) is higher.

  Here, the gaming state setting means 41 sets the gaming state according to the type of the special figure jackpot symbol displayed on the special figure indicators 18a and 18b, and the normal jackpot symbol A is displayed as shown in FIG. In such a case, after the jackpot game based on the normal jackpot symbol A, the time reduction state is set first, and then the normal state is set when the number of changes in the special symbol reaches a specified number (for example, 100 times) in the time reduction state. When the probability variation 1 big hit symbol B is displayed, the probability variation 1 state is set after the big hit game based on the probability variation 1 big hit symbol B. However, if a big hit game based on the probability change 1 big hit symbol B occurs in the probability change 1 and 2 states, the probability change 2 state is set after the big hit game. When the first and second probability variation 2 big hit symbols C1 and C2 are displayed, the probability variation 2 state is set after the big hit game based on the first and second probability variation 2 big hit symbols C1 and C2.

  The winning lottery means 47 performs a winning lottery by the passage of the game ball to the gate 12, and the ordinary figure display control means 48 is normally activated by the passage of the game ball to the gate 12 through the control of the ordinary figure display 18c. When the symbol is variably displayed on the general symbol display 18c and stopped, and the winning lottery means 47 wins the winning symbol, the common symbol big hit symbol is displayed on the universal symbol display 18c as the stopped symbol after the normal symbol fluctuates. Display.

  The starting port control means 49 is won by winning lottery by the winning lottery means 47 through the control of the second special figure starting port device 11 (second special figure starting port SOL11d), and the big figure display 18c is won by the big figure. When the symbol is displayed, the second special figure starting port 11a is opened and closed one or more times to generate an auxiliary game.

  As shown in FIGS. 10 and 11, the start port operation control mode setting means 49a has eight different start operations as the start port operation control mode for controlling the operation of the second special view start port 11a (opening / closing member 11b). One of the mouth operation control modes MX, MY1 to MY6, MZ is selected and set according to the gaming state set by the gaming state setting means 41.

  In this case, the start port operation control mode setting unit 49a sets the start port operation control mode MX when the normal state (first game state) is set by the game state setting unit 41, as shown in FIG. When the probability variation 1 state (second game state) is set, any one of the start port operation control modes MY1 to MY6 is set, and the probability variation 2 state (third game state) or the time reduction state is set. In this case, the start opening operation control mode MZ is set. As for the setting of the start port operation control mode MY, as shown in FIG. 13, any one of the start port operation control modes MY1 to MY6 is set according to the kind of probability variation 1 big hit symbol.

  The eight start opening operation control modes MX, MY1 to MY6, MZ are for controlling the start opening winning number expectation values for the game balls to win the second special figure start opening 11a different from each other. The parameters are the normal figure change time for changing the normal symbol on the display 18c, the normal figure winning probability won in the winning lottery, and the starting opening / closing pattern for opening and closing the second special figure starting opening 11a when winning in the winning lottery. Different modes are set depending on the combination of these parameters.

  When comparing the start port operation control modes MX, MY1, and MZ, the normal time variation time (5 s) of the start port operation control mode MY1 is set shorter than the normal time variation time (25 s) of the start port operation control mode MX, It is set to be the same as the normal time fluctuation time (5 s) of the start opening operation control mode MZ. The winning probability (1/50) of the starting opening operation control mode MY1 is set lower than the winning probability (50/50) of the opening opening operation control mode MZ. It is set to be the same as the probability (1/50). The start port opening time of the start port opening / closing pattern (3s × 1) in the start port operation control mode MY1 is set longer than the start port opening time of the start port opening / closing pattern (0.1s × 1) in the start port operation control mode MX. The start opening time of the start opening / closing pattern (3 s × 1) in the start opening operation control mode MZ is set to be the same.

  In addition, as shown in FIG. 12, in the start opening operation control mode MX, the normal symbol starts to fluctuate and stops fluctuating after 25 s. Therefore, if the winning lottery is won with a probability of 1/50, After the symbol is displayed, the second special figure starting port 11a is opened and closed so as to open once for 0.1 seconds. If the normal symbol variation is stopped and the winning lottery is selected, the normal symbol variation starts after the opening and closing of the second special diagram starting port 11a. Even when a game ball is launched aiming at the second special figure starting port 11a, the expected value of the starting port winning number at which the game ball wins the second special figure starting port 11a during execution of the start port operation control mode MX is very high. It becomes low.

  In the start-up operation control mode MY1, the normal symbol starts to fluctuate and stops fluctuating after 5 s. Therefore, if the winning lottery is won with a probability of 1/50, after the symbol per symbol is displayed, the second special figure is displayed. The start port 11a is opened and closed so as to open once for 3 seconds. Thereafter, the normal symbol starts to fluctuate in the same manner. The expected start opening prize number during execution of the start opening operation control mode MY1 is higher than the expected start opening prize number during execution of the start opening operation control mode MX.

  In the start-up operation control mode MZ, the normal symbol starts to fluctuate and stops fluctuating after 5 s. Therefore, if the winning lottery is won with a probability of 50/50, that is, when the normal symbol fluctuates, the symbol per symbol is always After the symbol is displayed, the second special figure starting port 11a is opened and closed so as to open once for 3 seconds. Thereafter, the normal symbol starts to fluctuate in the same manner. The expected start opening prize number during execution of the start opening operation control mode MZ is higher than the expected start opening prize number during execution of the start opening operation control mode MY1.

  That is, the expected start opening prize number during execution of the start opening operation control mode MY1 is higher than the expected start opening prize winning number during execution of the start opening operation control mode MX and during execution of the start opening operation control mode MZ. It becomes lower than the expected value of the starting opening winning number, and among the three starting opening operation control modes MX, MY1, and MZ, the starting opening operation control mode MY1 becomes a new mode that does not exist conventionally.

  In addition, although the above detailed description equivalent to each of the start opening operation control modes MY2 to MY6 is omitted, the respective modes become new modes that do not exist conventionally, and the start opening winning numbers during the execution of the respective modes. The expected value is higher than the expected start opening prize number during execution of the start opening operation control mode MX and lower than the expected start opening prize number during execution of the start opening operation control mode MZ.

  The start opening operation control mode setting means 49a is a state in which a probability variation 1 state (second game state), which is a predetermined gaming state among a plurality of gaming states, is set by the gaming state setting means 41, and at the time of setting (probability variation). When a set period elapses from the time of setting one state), a start port operation control mode changing means 49b is provided for changing the set start port operation control mode to another start port operation control mode. The set period is a period required from the time when the probability variation 1 state is set until the number of times the first special symbol fluctuates reaches the set number.

  As shown in FIG. 13, specifically, the start opening operation control mode changing means 49b is configured such that when the start opening operation mode MY1 corresponding to the probability variation 1 big hit symbol B1 is initially set, the first special symbol variation number is 50 times. When (first set number of times) is reached, the start port operation mode MY1 is changed to MY2, and when the first special symbol variation number reaches 100 times (second set number), the start port The operation mode MY2 is changed to MY6.

  In addition, when the start port operation mode MY2 corresponding to the probability variation 1 big hit symbol B2 is initially set, the start port operation control mode changing means 49b has reached 50 times (the first set number of times) in the first special symbol. In this case, the start port operation mode MY2 is changed to MY3, and the start port operation mode MY3 is changed to MY5 when the first special symbol variation count reaches 100 times (second set number). .

  In addition, when the start port operation mode MY3 corresponding to the probability variation 1 big hit symbol B3 is initially set, the start port operation control mode changing means 49b starts when the number of times of change of the first special symbol reaches 100 times (set number of times). The mouth operation mode MY3 is changed to MY4. However, when the start port operation modes MY4, MY5, and MY6 corresponding to the probabilistic 1 big hit symbols B4, B5, and B6 are initially set, the setting of the start port operation mode is not changed.

  Here, it is assumed that the starting opening winning number expectation number that the game ball wins in the second special figure starting opening 11a is increased in the order of the starting opening operation mode MY1-> MY2-> MY3-> MY4-> MY5-> MY6. The mode changing unit 49b changes the setting to the start port operation control mode in which the start port winning number expected value is higher than the set start port operation control mode before the change.

  The start port control means 49 is adapted to change the start port operation control mode according to the normal time variation time, the normal winning probability, and the start port opening / closing pattern of the start port operation control mode set by the start port operation control mode setting means 49a. If the start opening operation control mode is changed in 49b, the operation of the second special figure start opening 11a is performed in accordance with the normal time fluctuation time, the normal winning probability, and the start opening / closing pattern of the changed start opening operation control mode. To control.

  The start port operation control mode changing unit 49b may be changed as follows. The start opening operation control mode changing means 49b is configured to change the number of times of change of the second special symbol to the set number of times, or the sum of the number of changes of the first special symbol and the number of times of change of the second special symbol reaches the set number of times. If this happens, change the start port operation mode. Alternatively, the starting port operation control mode changing unit 49b changes the setting of the starting port operation mode when the number of times of changing the normal symbol reaches the set number. Further, the start port operation control mode changing means 49b changes the setting to the start port operation control mode in which the expected start port winning number is lower than the set start port operation control mode before the change.

  Further, the start opening operation control mode changing means 49b performs a setting change lottery when the number of changes of the special symbol (or the normal symbol) reaches the set number of times or for each change of the special symbol (or the normal symbol). The start port operation control mode is changed only when the setting change lottery is won. Further, the start port operation control mode changing means 49b selects the start port operation control mode to be set by lottery when changing the start port operation control mode.

  The prefetch determination means 50 determines whether or not to perform a prefetch effect using a lottery value (big hit random number) of a big hit lottery performed by winning when a game ball is won in the special figure starting port 10 or 11a.

  The external output processing means 51 includes, as game information, game ball launch related information capable of calculating the total number of game balls fired, special figure change related information capable of calculating the total number of changes in special symbols, and the total number of paid out game balls. In addition to game ball payout-related information that can be calculated, if special figure jackpot symbols are displayed on the special figure indicators 18a and 18b, the type of the special figure jackpot symbol (normal jackpot symbol, probability variable one jackpot symbol, probability variation two jackpot symbol) The jackpot related information that can be identified) is output to the external hall computer HC via the panel external information terminal board 26.

  In the hall computer HC to which a plurality of pachinko gaming machines 1 are connected, for example, based on the game information input from each pachinko gaming machine 1, for example, the total number of fluctuations of special symbols relative to the total number of game balls emitted from each pachinko gaming machine 1 ( Hereinafter, the ratio of special figure fluctuation frequency) can be calculated. In this case, a special figure fluctuation frequency is calculated for each gaming state of each pachinko gaming machine 1 (divided into a normal state, a probability variation 1 state, a short-time state and a probability variation 2 state), and thereby, the first special figure starting port 10 wins a prize. The rate can be calculated. Then, based on the winning rate of the first special figure starting port 10, the inclination of the obstacle nail near the upper part of the first special figure starting port 10 is adjusted so that the difficulty level of winning the first special figure starting port 10 is increased. Can be adjusted.

  Next, as shown in FIG. 14, the pachinko gaming machine 1 includes an effect control means 60 constituted by a computer of the effect control board 23, and further by an image control board 24 and a lamp control board 25, and its effect control. The means 60 controls the effect device 69 such as the image display 16, the movable accessory device 17, the speaker 34, the frame lamp 35, the panel lamp 36, etc., and the effect device 69 is a big hit during the change of special symbols as a game effect. The jackpot lottery effect related to the lottery is executed, the jackpot effect is executed during the jackpot game, and various other effects are executed.

  The effect control means 60 includes a normal effect selection means 61, a time-shortage effect selection means 62, a probability variation 1 effect selection means 63, a probability variation 2 effect selection means 64, and a big hit effect selection means 65, and the game set by the game state setting means 41 The effect selection means (any one of 61 to 65) corresponding to the state selects an effect to be executed by the effect device 69.

  The effect selecting means 61 to 64 are based on the result of the big hit lottery by the big hit lottery means 42, respectively, and in the case of winning by the big hit lottery, the special figure big hit symbol selected by the special figure big hit symbol selecting means 43 is selected. Based on this, the jackpot lottery effect to be executed by the rendering device 69 is selected from a plurality of types of jackpot lottery effects. In addition, multiple types of big hit lottery effects start the basic effect at the start of the change of the special symbol, the one that completes the effect with the end of this basic effect, the start of the development effect after the basic effect, and the end of the development effect It is roughly divided into those that complete the production.

  In particular, the probability change 1 effect selection means 63 is a first special lottery effect that is a game effect to be executed by the effect device 69 in a state where the probability change 1 state (second game state) is set by the game state setting means 41. The first effect selection means 63a for selecting the first big hit lottery effect according to the winning of the game ball in the figure starting port 10 and the second big hit lottery effect according to the winning of the game ball at the second special figure starting port 11a And it has the 2nd production | presentation selection means 63b which selects the 2nd big hit | lottery lottery production in which the 1st big hit lottery production and the production | generation aspect differ.

  The second big hit lottery effect suggests that the selection rate for selecting the big winning opening opening / closing pattern PC2 having the largest expected value for the big winning opening when winning in the big hit lottery is higher than the first big hit lottery effect. In addition, the jackpot lottery effect (that is, the normal effect selection means 61, which the effect control means 60 executes based on the winning of the game ball to the second special figure starting port 11b in the normal state, the short time state, and the probability variation 2 state. This is an effect in which the effect mode is different from the jackpot lottery effect selected by the time-shortage effect selecting means 62 and the probability variation 2 effect selecting means 64.

  Thereby, the effect control means 60 displays the effect image of the big hit lottery effect on the image display 16 which is the effect device 69 as the big hit lottery effect, and the image (background image) of the first big hit lottery effect in this big hit lottery effect image. And the image (background image) of the second big hit lottery effect. For example, as shown in FIGS. 15A and 15B, the background images of the first and second big hit lottery effects are substantially the same, but the background image of the first big hit lottery effect is displayed in blue. On the other hand, the background image of the second big hit lottery effect is displayed in red.

  The effect control means 60 can display effect characters and effect icons that are not displayed in the first jackpot lottery effect in the second jackpot lottery effect in the second jackpot lottery effect. For example, as shown in FIG. 15 (b), in the big hit lottery effect image, in the second big hit lottery effect, a production character of “Dai! The effect characters and the effect icons are not displayed in the first big hit lottery effect shown in 15 (a).

  In addition, the effect control means 60 varies the plurality of first effect symbols and the plurality of second effect symbols that are more advantageous (higher rank) to the player than the first effect symbols in the jackpot lottery effect image, and the gaming state With the probability changing state 1 (second gaming state) set by the setting means 41, the game ball to the first special figure starting port 10 is determined with respect to the symbol ratio of the number of second effect symbols to the number of first effect symbols. The ratio during the second big hit lottery effect performed by winning the game ball to the second special figure starting port 11a is higher than the ratio during the first big hit lottery effect made by winning.

  For example, in the big hit lottery effect image, a plurality of first and second effect symbols are variably displayed over three columns. In each row, as shown in FIG. Five even symbols (0, 2, 4, 6, 8) as the first effect symbols and five odd symbols (1, 3, 5, 7, 9) as the second effect symbols are variably displayed. As shown in FIG. 16 (b), in the second big hit lottery effect, the even number symbols (4, 6) as two first effect symbols and the odd number symbols (1, 3 as five second effect symbols). , 5, 7, 9) are variably displayed. In other words, the ratio of the number of symbols in the second big hit lottery effect (5/2 = rather than the ratio of the number of second effect symbols to the number of first effect symbols in the first big lottery effect (5/5 = 1). 2.5) is higher.

  Here, when winning in the big hit lottery, when the normal big hit symbol A is selected, the production big hit symbol (for example, 222) in which the same three first effect symbols are arranged is displayed, and the probability variation 1 big hit symbol B is selected. In a case where a predetermined effect big hit symbol (for example, 123) that does not match the same effect symbol is displayed. In addition, when winning in the big hit lottery, when the first or second probability variation 2 big hit symbol C1 or C2 is selected, an effect big hit symbol (for example, 777) in which three same second effect symbols are arranged is displayed. . However, in this case, it is also possible to display an effect jackpot symbol in which the same three first effect symbols are arranged, and later notify that the first or second probability variation 2 jackpot symbol C1 or C2 has been selected.

  Furthermore, when the pre-reading determination unit 50 determines that the pre-reading determination unit 50 performs the production control unit 60, the special design by the winning of the game ball to the special figure start ports 10 and 11a that are the targets of the positive determination. The pre-reading effect is executed before the end of the change, but the execution of the pre-reading effect in the probability variation 1 state (second game state) is prohibited. Therefore, the determination by the prefetch determination unit 50 may not be performed in the probability variation 1 state.

  For example, the first and second special figure hold lamps 18d and 18e displayed on the first and second special figure hold lamps 18d and 18e are displayed on the image display 16 as a special figure hold icon. The special figure hold icon resulting from the winning of the game ball to the special figure starting port 10 or 11a that is the object of the affirmative determination may be displayed as an icon different from the normal special figure hold icon, or the object of the affirmative determination Any pre-reading notice (for example, the action at the time of starting the change is different from normal) may be performed during each change performed until the end of the change of the special symbol of the game ball to the special figure starting ports 10 and 11a. .

  The probability variation 1 effect selection means 63 is at least a part of the performance until the special symbol reaches the set number of times (50 times or 100 times) from when the probability variation 1 state is set. (For example, the background screen) may be different. Thereby, after the special symbol reaches the set number of times, it can be notified that the start port operation mode has been changed.

  Next, the processing executed by the computer of the game control board 21 to achieve the functions of the respective means 41 to 51 of the game control means 40, and the computer of the effect control board 23, the respective means 61 to 61 of the effect control means 60. Processing executed to achieve the function 65 will be described based on a flowchart.

  As shown in FIG. 17, the timer interrupt process executed by the computer of the game control board 21 is started every minute time (2 ms). In this timer interrupt process, random number update process (S1), switch process (S2) The symbol process (S3), the electric accessory process (S4), the prize ball process (S5), and the output process (S6) are sequentially executed.

  As shown in FIG. 18, in the start port SW process in S2, when the first special figure start port SW10a is on (S11; Yes), when the first special figure reservation number U1 is less than 4 (S12; Yes) The first special figure holding number U1 is added to U1 + 1 (S13), the big hit random number, the big hit symbol random number and the reach random number are acquired and stored (S14), and the first special figure holding number increase command is set (S15). . Subsequently, a prefetch determination process (S16) is executed based on the jackpot random number acquired in S14, and when a prefetch effect is executed (S17; Yes), a prefetch command is set (S18).

  Next, when the second special figure starting port SW11c is on (S19; Yes), when the second special figure reservation number U2 is less than 4 (S20; Yes), the second special figure reservation number U2 is set to U2 + 1. Add (S21), acquire / store the jackpot random number, jackpot symbol random number and reach random number (S22), and set the second special figure reservation number increase command (S23). Subsequently, a prefetch determination process (S24) is executed based on the jackpot random number acquired in S22, and when a prefetch effect is executed (S25; Yes), a prefetch command is set (S26). Note that the commands set in S15, S18, S23, and S26 and the commands set in the steps of other routines are transmitted to the effect control board 23 by the output process of S6, and the external output among them is output. The required command is sent to the hall computer HC.

  As shown in FIG. 19, in the special symbol processing in S3, when the hit state flag is not ON (that is, during big hit game or small hit game) (S31; No), when the special symbol is not changing (S32; No) First, it is determined whether or not the second special figure hold number U2 is 1 or more (S33). If the determination in S33 is Yes, the second special figure hold number U2 is subtracted from U2-1 (S34). If the determination in S33 is No, it is next determined whether or not the first special figure hold number U1 is 1 or more (S35). If the determination in S35 is Yes, the first special figure hold number U1 is set to U1-1. Subtract (S36).

  After S34 and S36, the customer waiting flag is turned off (S37), the big hit determination process (S38) is executed, and then the variation pattern (time) selection process (S39) is executed. If the determination in S35 is No, a customer waiting setting process (S46) is executed.

  As shown in FIG. 20, in the big hit determination process of S38, first, a big hit random number determination process (S51) is executed, and whether or not the big hit is determined based on the big hit random number corresponding to the value subtracted in S34 or S36. If it is determined (S52) and the determination of S52 is No, it is determined whether or not a small hit is made (S53), and if the determination of S53 is No, the game is lost. When the big hit random number matches the big hit specific value, the determination of S52 is Yes, but as shown in FIG. 6, the winning probability of the big hit lottery is about 1/370 in the normal state and the short time state. The big hit specific value is set to be about 1/50 in the probability variation 1 state and the probability variation 2 state.

  If the determination in S52 is Yes, then a big hit symbol random number determination process (S54) is executed, and a special symbol big hit symbol is set based on the big hit symbol random number corresponding to the one subtracted in S34 or S36. (S55). In this case, with the big hit symbol random number acquired by winning the game ball to the first special figure starting port 10 as the special symbol big hit symbol, the normal big hit symbol A, the probability variable one big hit symbol B, the first probability variable two big hit symbol C1, the first One of the two probabilistic 2 big hit symbols C2 is selected and set at the selection rate shown in FIG. 8 (1), and the big hit symbol random number acquired by winning the game ball to the second special figure starting port 11a is usually the big hit symbol A Any one of the first probability variation 2 big hit symbol C1 and the second probability variation 2 big hit symbol C2 is selected and set at the selection rate shown in FIG.

  However, as the probability variation 1 big hit symbol B, one of probability variation 1 big hit symbols B1 to B6 shown in FIG. 13 is selected and set as described above. If the determination in S53 is Yes, a special figure small hit symbol is set (S56), and if the determination in S53 is No, a special figure loss symbol is set (S57).

  As shown in FIG. 21, in the variation pattern selection process of S39, first, it is determined whether or not it is a big hit (S61), and if the determination of S61 is No, a reach random number determination process (S62) is executed, where S34 or Based on the reach random number corresponding to the value subtracted in S36, it is determined whether or not it is reach (S63). If the determination in S61 is Yes, the jackpot table is set (S64). If the determination in S63 is Yes, the reach table is set (S65). If the determination in S63 is No, the lose table is set. (S66).

  After S64 to S66, the fluctuation pattern random number is acquired and stored (S67), the current gaming state and the special figure holding number are read (S68), and the fluctuation pattern random number determination process (S69) is executed. Therefore, a variation pattern (special diagram variation time) is set based on the table set in S64 to S66, the variation pattern random number obtained in S67, the gaming state read in S68 and the number of special figure hold (S70). .

  As shown in FIG. 19, after execution of the variation pattern selection process of S39, the first or second special symbol is started to vary (S40), and the special symbol stop symbol type and variation pattern set in S38 and S39 are A change start command including information that can identify the type of the special symbol to be changed (first or second special symbol) is set (S41). After that, or if the determination in S32 is Yes, it is determined whether or not the special figure variation time set in S39 has elapsed (S42). If the determination in S42 is Yes, the first or second special symbol is suspended. (S43), where the stop symbol of the special symbol set in S38 is stopped and displayed on the first or second special symbol indicator 18a or 18b. Next, a variable stop command is set (S44), and the stop process (S45) is executed.

  As shown in FIG. 22, in the stop process of S45, first, when the time reduction state flag is ON (S81; Yes), the time reduction limit number J is subtracted from J-1 (S82), and then J = 0. In the case (S83; Yes), the time reduction state flag is turned OFF (S84). When the probability variation 1 state flag is ON (S85; Yes), the probability variation 1 limit number X1 is subtracted from X1-1 (S86). Thereafter, when X1 = 0 (S87; Yes), the probability variation 1 state flag is turned OFF. (S88).

  When the probability variation 2 status flag is ON (S89; Yes), the probability variation 2 limit number X2 is subtracted from X2-1 (S90), and then when X2 = 0 (S91; Yes), the probability variation 2 status flag is turned OFF. (S92). The gaming state is set to the time-saving state when the time-saving state flag is ON, is set to the probability-changing 1 state when the probability-changing 1 state flag is ON, and is set to the probability-changing 2-state when the probability-changing 2 state flag is ON. When all of the status flag, the probability variation 1 status flag, and the probability variation 2 status flag are OFF, the normal status (or big hit status) is entered.

  Next, as shown in FIG. 23, it is determined whether or not it is a big hit (S93). If the determination in S93 is No, it is determined whether or not it is a small hit (S94). If the determination in S93 is Yes, a long big hit ( (S95), if the determination in S95 is No, it is determined whether or not a medium big hit (selects the large winning opening / closing pattern PA, PC1), and the determination in S96 In the case of No, it becomes a short and big hit (selects the big winning opening / closing pattern PB).

  If the determination in S94 is Yes, the small hit state flag is turned on (S97), if the determination in S95 is Yes, the long hit state flag is turned on (S98), and if the determination in S96 is Yes, the medium big hit state flag Is turned ON (S99), and if the determination in S96 is No, the short hit state flag is turned ON (S100). After S98 to S100, the time reduction limit count J, the probability variation 1 limit count X1, and the probability variation 2 limit count X2 are reset (S101), and the time reduction status flag, the probability variation 1 status flag, and the probability variation 2 status flag are turned OFF (S102). After S97 and S102, opening is started (S103), and an opening command is set (S104).

  As shown in FIG. 24, in the big prize opening process in S4, it is determined whether or not the hit state flag (big hit state flag or small hit state flag) is ON (S111). If the determination in S111 is Yes, the winning game It is determined whether or not it is during the opening before the first big winning opening 13a is opened (S112). If the determination in S112 is Yes, it is determined whether or not the opening time has elapsed (S113), and if the determination in S113 is Yes, a special winning opening opening / closing pattern setting process (S114) is executed.

  In the big winning opening / closing pattern setting process of S114, in the case of a big win, as shown in FIG. 9, a big winning opening / closing pattern corresponding to the type of special figure big hit symbol is set, and as shown in FIG. The Rc and R maximum operation time Tc are set to values corresponding to the set special prize opening / closing pattern (for example, in the case of the big prize opening / closing pattern PA, the maximum Rc = 4 and the R maximum operation time Tc = 30 s). . In the case of a small hit, a big winning opening / closing pattern similar to the big winning opening / closing pattern PB is set.

  On the other hand, if the determination in S112 is No, it is determined whether or not the ending after the last winning prize opening 13a of the winning game is closed (S115). If the determination in S115 is No, is the winning prize opening 13a active? It is determined whether or not (S116). After S114 or when the determination in S116 is No, R is added to R + 1 (S117), the operation of the big prize opening 13a is started (the big prize opening 13a is opened) (S118), and the R operation time T Timekeeping is started (S119), and measurement of the number N of winning game balls to the second special figure starting port 11a is started (S120).

  If the determination in S116 is Yes, or after S120, it is determined whether or not T ≧ R maximum operation time Tc (S121). If the determination in S121 is No, N ≧ specified number Nc (for example, Nc = 10). Whether or not (S122). If the determination in S121 is Yes or the determination in S122 is Yes, the operation of the special prize opening 13a is ended (the special prize opening 13a is closed) (S123), T and N are reset (S124), and R = maximum Rc? It is determined whether or not (S125).

  If the determination in S125 is Yes, ending is started (S126), an ending command is set (S127), R is reset to 0 (S128), and it is determined whether the ending time has elapsed (S129). If the determination in S129 is Yes, a game state setting process (S130) is executed, and the winning state flag is turned OFF (S131).

  As shown in FIG. 26, in the game state setting process of S130, first, it is determined whether or not it is a small hit (S141). If the determination of S141 is No, it is a normal big hit (the special figure big hit symbol is a normal big hit symbol). (S142). If the determination in S142 is No, it is determined whether or not the probability variation 1 big hit (the special figure big hit symbol is the probability variation 1 big hit symbol) (S143). Or 2nd probability variation 2 big hit symbol).

  If the determination in S142 is Yes, the time reduction state flag is turned on (S144), the time reduction limit count J is set to 100 (S145), and if the determination in S143 is Yes, the probability variation 1 state flag is turned on (S146). ), The probability variation 1 limit number X1 is set to 10000 (S147), and if the determination in S143 is No, the probability variation 2 state flag is turned ON (S148), and the probability variation 2 limit number X2 is set to 10000 (S149). In the case of a small hit, the current gaming state is maintained.

  As shown in FIG. 27, in the gate SW processing in S2, when the gate SW 12a is on (S151; Yes), and when the general figure reservation number G is less than 4 (S152; Yes), the general figure reservation number G is set. Add to G + 1 (S153), and acquire and store a winning random number (S154).

  As shown in FIG. 28, in the normal symbol process in S3, first, the idle start port operation control mode setting process (S161) is executed, where any one of the start port operation control modes MX, MY1 to MY6, MZ is executed. Can be set. After that, when the auxiliary game flag is not ON (that is, during the auxiliary game) (S162; No), when the normal symbol is not fluctuating (S163; No), and when the normal figure holding number G is 1 or more (S164) ; Yes), hit random number determination processing (S165) is executed.

  In the hit random number determination process in S165, it is determined whether or not a hit is made based on the hit random number corresponding to the value subtracted in S164. When the winning random number matches the winning specific value, the winning probability is the probability indicated by the starting port operation control mode set in S161 (for example, about 1 in the starting port operation control modes MX and MY1). / 50, 50/50 in the start opening operation control mode MZ), the hit specific value is set.

  Next, a stop symbol setting process (S166) is executed, and as a result of the determination in S165, a symbol per symbol is set in the case of winning, and a symbol losing symbol is set in the case of loss. Next, the normal time change time setting process (S167) is executed, and the time indicated by the start port operation control mode set in S161 is set as the normal time change time (for example, 25 s in the start port operation control mode MX, the start time) 5s) is set in the mouth operation control modes MY1 and MZ. Thereafter, the variation of the normal symbol is started (S168).

  If the determination in S163 is Yes, or after S168, it is determined whether or not the normal map change time set in S167 has passed (S169). If the determination in S169 is Yes, the normal symbol is suspended and stopped (S170). Here, the stop symbol of the normal symbol set in S166 (the symbol per symbol per symbol or the symbol of the common symbol) is stopped and displayed on the symbol display 18c. In the case of winning (S171; Yes), the auxiliary game flag is turned ON (S172).

  Here, as shown in FIG. 29, in the start port operation control mode setting process in S163, it is first determined whether or not the gaming state is changed (S181). If the determination in S181 is Yes, the changed gaming state is set. A corresponding start port operation control mode is set (S182). Next, it is determined whether or not the changed gaming state is the probability variation 1 state (S183). If the determination in S183 is Yes, it is determined whether or not the start port operation control mode (MY1 to MY3) to be changed is set. (S184). If the determination in S184 is Yes, the mode change processing flag F is set to 1 and the special figure fluctuation count N is reset to 0 (S185).

  After S185, or when the determination of S181, S138, or S184 is No, it is determined whether or not the mode change processing flag F = 1 (S186). If the determination of S186 is Yes, a special symbol (first special symbol) When the fluctuation stops (S187; Yes), the special figure fluctuation number N is added to N + 1 (S188), and it is determined whether or not the special figure fluctuation number N is the set number NC (NC = 50 times, 100 times). (S189). When the determination in S189 is Yes, the start port operation control mode setting is changed (S190) as described with reference to FIG. Thereafter, when the mode change process is completed (S191), the mode change process flag F is reset to 0 (S192).

  As shown in FIG. 30, in the starting port process in S4, it is determined whether or not the auxiliary game flag is ON (S201). If the determination in S201 is Yes, it is determined whether or not the second special figure starting port 11a is in operation. (S202). When the determination in S202 is No, a start port opening / closing pattern setting process (S203) is executed, and therefore, a pattern indicated by the start port operation control mode set in S163 as the start port opening / closing pattern (for example, the start port operation control mode). MX is set to 0.1 s × 1, and starter operation control modes MY1 and MZ are set to 3 s × 1).

  Thereafter, the operation of the second special figure starting port 11a is started (the second special figure starting port 11a is opened) (S204), and control is performed so that the start port opening / closing pattern set in S203 is obtained. If the determination in S202 is Yes, or after S204, it is determined whether the start port operating time of the start port opening / closing pattern set in S203 has passed (S205), and if the determination in S205 is Yes, the second The operation of the special figure start port 11a is terminated (the second special figure start port 11a is closed) (S206), and the auxiliary game flag is turned OFF (S207).

  As shown in FIG. 31, the timer interrupt process executed by the computer of the effect control board 23 is started every minute time (2 ms). In this timer interrupt process, a command reception process (S301) and an effect button process (S302) are performed. ), Command transmission processing (S303) is sequentially executed.

  As shown in FIG. 32, the command reception process of S301 is a routine for executing various processes based on the command received from the game control board 21. First, when a hold number increase command is received (S311; Yes), A number addition process (S312) is executed, and a pending number command is set (S313). Note that the command set in S313 and the command set in other steps are transmitted to the image control board 24 and the lamp control board 25 by the command transmission processing in S303, and an external output is required. The command is sent to the hall computer HC.

  Next, when a change start command is received (S314; Yes), an effect selection process (S315) is executed, and the effect selection process causes the jackpot lottery effect to be executed by the effect device 69 among a plurality of types of jackpot lottery effects. Selected from. In this case, a plurality of effect tables corresponding to a plurality of game states are provided, and based on the effect table corresponding to the current game state, the special symbol stop symbol type and the variation pattern identified from the variation start command ( The jackpot lottery effect is selected based on the special figure fluctuation time. The current game state is grasped by a game state command transmitted from the computer of the game control board 21.

  In this effect selection process, in particular, in the state in which the probability variation 1 state (second game state) has been set, based on the special symbol type (first or second special symbol) further identified from the variation start command, When the special symbol changes, the first big hit lottery effect is selected accordingly, and when the second special symbol changes, the second big hit lottery effect corresponding to the first big hit lottery effect is selected. A second big hit lottery effect having a different effect mode is selected.

  As a result, the jackpot lottery effect image is displayed on the image display 16 as the jackpot lottery effect. As described with reference to FIG. 15, the background image of the first jackpot lottery effect and the second jackpot lottery effect in this jackpot lottery effect image. Different from the background image, the effect characters and effect icons that are not displayed in the first jackpot lottery effect in the jackpot lottery effect image can be displayed in the second jackpot lottery effect. Further, in the big hit lottery effect image, the plurality of first effect symbols and the plurality of second effect symbols that are more advantageous to the player than the first effect symbol are fluctuated. As described with reference to FIG. Regarding the ratio of the number of the second effect symbols to the number of symbols, the ratio during the second big hit lottery effect is higher than the ratio during the first big hit lottery effect.

  Next, when a prefetch command is received (S316; Yes), a prefetch effect selection process (S317) is executed, and the special figure starting port 10, which is determined to perform the prefetch effect by this prefetch effect selection process, The pre-reading effect is executed before the end of the change of the special symbol due to the winning of the game ball to 11a. However, execution of the pre-reading effect in the probability variation 1 state is prohibited.

  When the change stop command is received (S318; Yes), the process of changing effect end (S319) is executed. When the opening command is received (S320; Yes), the hit effect selection process (S221) is executed and the ending command is executed. Is received (S322; Yes), an ending effect selection process (S323) is executed, and finally a customer waiting command reception process (S324) is executed.

The operation and effect of the above pachinko gaming machine 1 will be described.
When the gaming state is the normal state, the start port operation control mode MX is set, the normal time variation time is 25 s, the normal game win probability is 1/50, and the start port opening / closing pattern is 0.1 s × 1. The expected value of the number of start-up winnings at which a game ball wins the special figure starting port 11a is very low. That is, almost no winning of game balls to the second special figure starting port 11a can be expected, and most of the big win lottery is performed based on winning of the game balls to the first special figure starting port 10. .

  In other words, in the normal state, the rate of decrease of the game balls that are possessed balls increases until the big hit game is generated after winning the big hit lottery. Moreover, since the winning probability of the jackpot lottery is low (about 1/370), when winning in the jackpot lottery, most of the jackpot lottery is based on the winning of the game ball to the first special figure start opening 10. Since it is performed, the ratio (50%) of the big hit game in which the real ball is not obtained is large, and the ratio (15%) of the big hit game in which the maximum ball is obtained is small. This normal state is the most disadvantageous gaming state.

  When the gaming state is a short-time state, the start opening operation control mode MZ is set, the normal time variation time is 5 s, the normal drawing winning probability is 50/50, and the start opening / closing pattern is 3 s × 1. The expected value for the number of winnings at the starting port where a game ball wins at the starting port 11a is very high. That is, most of the jackpot lottery is performed based on winning of the game ball to the second special figure starting port 11a. That is, in the short-time state, the reduction rate of the game balls as the holding balls is reduced until the big hit game is generated after winning the big hit lottery, and the big hit lottery is performed one after another without substantially reducing the holding balls.

  However, the winning probability of the jackpot lottery is low (about 1/370) as in the normal state, and when the number of fluctuations of the special symbol reaches the specified number, the normal state is entered and the start opening operation control mode MX However, when winning in the big hit lottery, since most of the big hit lottery is performed based on the winning of the game ball to the second special figure starting port 11a, it becomes a big hit game in which a real out ball cannot be obtained. The ratio (0%) is small, and the ratio (65%) that is a big hit game with the maximum number of balls is increased. That is, the short time state is a gaming state that is more advantageous than the normal state.

  When the gaming state is in the probabilistic 2 state, the starting port operation control mode MZ is set in the same manner as in the short-time state. Therefore, the expected starting port winning number at which the game ball wins the second special figure starting port 11a is very high. Get higher. That is, most of the jackpot lottery is performed based on winning of the game ball to the second special figure starting port 11a. In other words, in the probability variation 2 state, until the big hit game is won and the big hit game is generated, the decrease rate of the game balls as the holding balls is reduced, and the big hit lottery is successively performed without substantially reducing the holding balls. .

  In addition, the probability variation 2 state is continued until the next big jackpot lottery is won, and the winning probability of the jackpot lottery is high probability (about 1/50). When winning the big hit lottery, most of the big hit lottery is the second Since it is based on the winning of a game ball to the special figure starting port 11a, the ratio (0%) of the big hit game in which the real ball can not be obtained is small and the ratio of the big hit game in which the maximum ball can be obtained ( 65%) increases. This probability variation 2 state is the most advantageous gaming state.

  By the way, in the conventional so-called latent state, the winning probability of the big hit lottery is high (about 1/50). However, since the start port operation control mode MX is set as in the normal state, the second special feature The expected value of the number of start-up winnings at which the game balls win the figure starting port 11a becomes very low, and most of the jackpot lottery is performed based on the winning of the game balls to the first special-type starting port 10.

  In other words, in the latent state, it is easy to win in the big hit lottery, but in the case of winning in the big hit lottery, most of the big hit lottery is performed based on the winning of the game ball to the first special figure starting port 10, so The ratio (50%) of the big hit game where the ball cannot be obtained is large, and the ratio (15%) of the big hit game where the maximum ball can be obtained is small. In other words, the fun in the state where the winning probability of the jackpot lottery is set to a high probability is halved, and the game performance cannot be improved.

  Therefore, in the present invention, the probability variation 1 state is adopted instead of the latent probability state, and when the gaming state is the probability variation 1 state, a new start port operation control mode MY1 that is different from the normal state, the time reduction state, and the probability variation 2 state. ~ MY6 is set, and the starting opening winning number expected value at which the game ball wins the second special figure starting opening 11a is larger than the starting opening winning number expected value when the starting opening operation control mode MX is set. It becomes higher and becomes lower than the expected value of the starting opening winning number when the starting opening operation control mode MZ is set.

  In other words, the percentage of the big hit game in which no real ball is obtained is higher than that in the probability variation 2 state and the short-time state, but is lower than the percentage in the normal state, resulting in the big hit game in which the maximum ball is obtained. The ratio is lower than that in the probability variation 2 state and the time-short state, but is higher than the ratio in the normal state. In other words, the probability variation 1 state is a gaming state that is more advantageous than the normal state, disadvantageous than the probability variation 2 state, and has a different advantage with respect to the short time state (for example, advantageous over the short time state).

  Then, the start port control means 48 is in the gaming state as one of the eight start port operation control modes MX, MY1 to MY6, MZ as the start port operation control mode for controlling the operation of the second special figure start port 11a. Since it has the start opening operation control mode setting means 48a for selecting and setting according to the gaming state set by the setting means 41, it is possible to improve the fun in the state where the winning probability of the big hit lottery is set to a high probability, Can be increased.

  The three start opening operation control modes MX, MY1 to MY6, MZ are controlled so that the start opening winning number expectation value at which the game ball wins the second special figure start opening 11a is different from each other. Depending on the start-up operation control mode, the ratio of the big hit game where the real ball can not be obtained and the ratio of the big hit game where the maximum ball can be obtained can be made different. Since the game can be controlled, the game performance can be improved with certainty.

  For example, in the start opening operation control mode MY1, the probability of a big hit is about 16% based on the winning of a game ball to the second special figure start opening 11a in the probability variation 1 state, and the number of special symbol fluctuations until the big hit is large. As it is, that is, as it gets more and more, the number of jackpot lotteries to be performed based on the winning of the game ball to the second special figure starting port 11a increases, so that the player gets a maximum hit game with the maximum number of balls. We can keep expectation.

  In the game area 4a, most of the plurality of ball paths in which the game balls may win the second special figure start port 11a are changed to the plurality of ball paths that may win the first special figure start port 10 as well. Since the first and second special figure starting ports 10 and 11a are arranged as described above, the game to the second special figure starting port 11a out of the first and second special figure starting ports 10 and 11a in the probability variation 1 state. There can be no ball path that can greatly increase only the winning rate of the ball, and after all, even if the so-called stop is made, only the winning rate of the game ball to the second special figure starting port 11a is greatly increased. In other words, it is possible to take measures that cannot inappropriately increase the ratio of the big hit game with which the maximum number of balls can be obtained.

  In addition, the ratio of selecting the special winning opening opening / closing pattern PC2 having the maximum expected value for the winning prize opening with respect to the number of fluctuations of the special symbol is as low as that in the normal state when the gaming state is the conventional latent state. The ratio does not change regardless of the duration of stay in the latent state. In other words, when the gaming state is in the latent state, it is easier to win in the big win lottery than in the normal state, but since it is a lottery, the number of fluctuations of the special symbol until winning in the big hit lottery may be very small. Sometimes it becomes very large. However, this cannot be reflected in the game characteristics, and the game characteristics cannot be improved in this respect.

  Therefore, in the present invention, when the start opening operation control mode setting means 48a is in the state in which the probability variation 1 state is set by the gaming state setting means 41, the number of fluctuations of the special symbol (first special symbol) from the setting time is the set number of times. When the set period required to reach is reached, the start port operation control mode changing means 49b for changing the set start port operation control mode to another start port operation control mode is provided. After reaching and reaching the set number of times, the start opening winning number expected value at which the game ball wins in the second special figure starting port 11a is changed, and the ratio of the big hit game in which the maximum payout is obtained is changed. be able to.

  In addition, the start opening operation control mode changing means 49b has a start opening operation with a higher expected start opening winning number for a game ball to win the second special figure start opening 11a than in the set start opening operation control mode before the change. Change the setting to control mode. In other words, in the probability variation 1 state, if the number of changes in the special symbol until winning in the jackpot lottery is small, the jackpot can be obtained continuously in a short time, so that the player can be satisfied. However, if the number of changes in the special symbol until winning in the big hit lottery is large, the player's stress increases if so-called fits. However, on the other hand, when the number of fluctuations of the special symbol reaches the set number of times, the starting number of winnings at which the game ball wins the second special figure starting port 11a is changed to be higher, and the maximum number of balls to be played is increased. Since the ratio of the big hit game to be obtained can be changed so as to increase, and the corresponding profit is reduced, the game performance can be enhanced in this respect.

  Further, the production control means 60 responds to the winning of the game ball to the first special figure starting port 10 as a big hit lottery production to be executed by the production equipment 69 in a state where the probability variation 1 state is set by the game state setting means 41. The first effect selection means 63a for selecting the first jackpot lottery effect, and the second jackpot lottery effect corresponding to the winning of the game ball to the second special figure starting port 11a, the first jackpot lottery effect and the effect mode are The probability variation 1 effect selecting means 63 has second effect selecting means 63b for selecting different second big hit lottery effects.

  That is, in the probability variation 1 state, it is performed based on the first big hit lottery effect performed based on the winning of the game ball to the first special figure starting port 10 and the winning of the game ball to the second special figure starting port 11a. Differentiating from the second jackpot lottery effect, whether the current jackpot lottery effect is based on the winning of a game ball to the first special figure start opening 10 or to the second special figure start opening 11a It is possible to clearly notify the player whether the game ball is based on winning a prize.

  Then, the second big hit lottery effect suggests that the selection rate for selecting the big winning opening opening / closing pattern PC2 having the maximum expected value for the big winning opening when winning in the big hit lottery is higher than the first big hit lottery effect. Therefore, when the second big hit lottery effect is performed, the ratio of the big hit game with which the maximum number of balls can be obtained increases, but the player sees the second big hit lottery effect, It is possible to raise the expectation that it will be a big hit game that wins by lottery and obtains the maximum number of balls.

  In the jackpot lottery effect image displayed on the image display 16 as a jackpot lottery effect, the effect control means 60 makes the background image of the first jackpot lottery effect different from the background image of the second jackpot lottery effect, and further, the first jackpot lottery effect image. Since the characters or icons that are not displayed in the lottery effect can be displayed in the second jackpot lottery effect, when the second jackpot lottery effect is being performed, it is advantageous for the player if the corresponding jackpot lottery is won Can clarify things.

  In addition, in the jackpot lottery effect image displayed on the image display 16 as a jackpot lottery effect, the effect control means 60 includes a plurality of first effect symbols and a plurality of second effect symbols that are more advantageous to the player than the first effect symbol. In the state in which the first probability variation state is set by the game state setting means 41, the game ratio to the number of the second effect symbols with respect to the number of the first effect symbols is the game to the first special figure starting port 10 More than the ratio during the first big hit lottery effect (for example, the ratio (5/5) based on FIG. 16 (a)) performed by winning the ball, the first performed by winning the game ball to the second special figure starting port 11a. The ratio of the two big hit lottery effects (for example, the ratio (5/2) based on FIG. 16B) is made higher, and the big winning opening opening / closing pattern PC2 with the maximum expected winning prize number is selected. If the second stage design is complete It was capable of displaying the second performance jackpot symbol.

  In other words, if the first big hit lottery effect is further differentiated from the second big hit lottery effect and the second big hit lottery effect is being performed, it is advantageous for the player if the corresponding big hit lottery effect is won. Can be further clarified. It should be noted that the symbol number ratio during the second big hit lottery effect can be changed, and this figure number ratio is the ratio corresponding to FIG. 8 (1) in the first big hit lottery effect, and FIG. 8 in the second big hit lottery effect. The ratio may correspond to (2).

  Further, when the prefetch determination unit 50 makes an affirmative determination, the effect control unit 60 starts the variation of the special symbol due to the winning of the game ball at the special figure starting port 10 or 11a that is the target of the positive determination. Although the pre-reading effect is executed, execution of the pre-reading effect in the probability variation 1 state is prohibited. In other words, if a pre-reading effect is performed in the probability variation 1 state, the target of the pre-reading effect is based on winning a game ball at the first special figure starting port 10, and the jackpot expectation is increased. This is a pre-read effect that is not desired for a player who wants to win a big hit based on the winning of a game ball at the second special figure starting port 11a, but this can be prevented.

  Next, another embodiment in which the first embodiment is partially changed will be described. However, components that are basically the same as those in the first embodiment are denoted by the same reference numerals and description thereof is omitted.

  As the start port operation control mode MY, start port operation control modes MY7 to MY9 shown in FIGS. 33 to 35 may be adopted. Specifically, in the start opening operation control mode MY7 shown in FIG. 33, the normal time fluctuation time is set to 10 s, the normal drawing winning probability is set to 1/50, and the start opening / closing pattern is set to 3 s × 1, and the start opening shown in FIG. In the operation control mode MY8, the normal time fluctuation time is set to 5 s, the normal signal winning probability is set to 1/50, and the start port opening / closing pattern is set to 1.5 s × 1, and in the start port operation control mode MY9 shown in FIG. The variation time is set to 10 s, the normal winning probability is set to 1/50, and the start opening / closing pattern is set to 1.5 s × 1. In addition to the start opening operation control modes MY7 to MY9, there are a plurality of start opening operation control modes having different combinations of the normal map variation time, the general drawing winning probability, and the start opening / closing pattern. The detailed explanation is omitted.

  As shown in FIG. 36, the start port control means 48 has a plurality of normal time change times (5 s, 5s, 5) as the normal time change time of one start port operation control mode MY10 corresponding to the probability variation 1 state (second game state). Any one of 5.5s, 6s) is adopted, and any one of a plurality of start opening / closing patterns (1s × 1, 2s × 1, 3s × 2) is used as the start opening / closing pattern. adopt. It should be noted that the normal winning probability (1/50) of the start opening operation control mode MY10 is unique. The normal time fluctuation time is selected from a plurality of normal time fluctuation times by a lottery using the normal time fluctuation time random number obtained together with the random number so as to have a selection rate shown in FIG.

  When generating an auxiliary game, as shown in FIG. 38, one of a plurality of types of symbols F1 to F3 is selected by lottery so as to have the selection rate shown in FIG. 39 and displayed on the diagram display 18c. Is done. The multiple types of symbols F1 to F3 per map correspond to a plurality of start opening / closing patterns (1 s × 1, 2 s × 1, 3 s × 2), and are displayed on the general map display 18c. A start opening / closing pattern corresponding to the symbol per figure is selected.

  If the normal symbol variation time and the starting opening / closing pattern when hitting are one way, if the player knows that, by controlling the launch of the game ball and performing the so-called stop, Although only the winning rate of the game ball to the start opening 11a may be increased to inappropriately increase the ratio of the big hit game with which the maximum ball can be obtained, it can be suppressed.

  As shown in FIG. 40, the start port control means 48 has a plurality of normal time change times (5s, 5s, 5), as the normal time change time of one start port operation control mode MY11 corresponding to the probability variation 1 state (second game state). Any one of 5.5s, 6s) is adopted, and any one of the plurality of start opening / closing patterns (PF4, PF5) is used as the start opening / closing pattern. It should be noted that the normal winning probability (1/50) of the start opening operation control mode MY11 is unique. The selection of the normal map change time is performed in the same manner as in the fifth embodiment.

  When generating an auxiliary game, as shown in FIG. 41, one of a plurality of types of symbols F4 and F5 is selected so that the selection rate shown in FIG. Is done. The plurality of types of symbols F4 and F5 per map correspond to the plurality of start port opening / closing patterns PF4 and PF5, respectively, and the start port opening / closing patterns corresponding to the symbols per map displayed on the map display 18c. Is selected.

  As shown in FIG. 43, in the start port opening / closing pattern PX, the second special figure start port 11a is opened / closed so as to open once for 0.1 seconds, and in the start port opening / closing pattern PZ, the second special figure start port is opened. 11a is opened / closed so as to open once for 3 seconds, and these are the same as the start opening / closing patterns PX, PZ in the first embodiment. On the other hand, in the start port opening / closing pattern PF4, as in the start port opening / closing pattern PZ, the second special figure start port 11a is opened and closed so as to open once for 3 seconds. In the start port opening / closing pattern PF5, the second special figure start is started. The mouth 11a is opened and closed so as to open twice for 0.6 seconds, and the interval time from the first closing of the second opening and closing of the second special figure starting port 11a to the second opening is 1. 5 seconds.

  Similar to the effect of the third embodiment, when the variation time of the normal symbol and the start opening / closing pattern when hitting is one, the player knows it and controls the launch of the game ball to perform so-called stoppage. There is a possibility that only the winning rate of the game ball to the second special figure starting port 11a can be increased to inappropriately increase the ratio of the big hit game in which the maximum output ball can be obtained, but this can be suppressed. Note that a start port opening / closing pattern such as the start port opening / closing pattern PF5 in which the second special figure start port 11a is opened and closed a plurality of times may be employed instead of the start port opening / closing pattern described in the other embodiments.

  A real ball is obtained at the time of the big hit, and the number of rounds and the selection rate thereof are changed to those other than those shown in FIGS. 7 to 9 of the first embodiment, and the game ball is won at the second special figure starting port 11a. When winning in the big hit lottery, the expected value of the number of game balls that can be obtained will be higher than in the case of winning in the big hit lottery performed by winning the game ball at the first special figure starting port 10 You may comprise.

  For example, as shown in FIG. 44, a real ball is obtained at the time of the big hit, and there are four rounds of 16R, 15R, 11R, 6R, and about 2100, about 200, respectively, of the rounds obtained. When the number of rounds is about 1000 and about 500, the selection rate for selecting the number of rounds is shown in FIG. 45 (1 when winning in the big hit lottery performed by winning a game ball to the first special figure starting port 10. ) And the ratio shown in FIG. 45 (2) when winning in the big hit lottery performed by winning the game ball to the second special figure starting port 11a.

  In addition, various modifications can be added without departing from the spirit of the present invention. Further, the present invention can be applied to various pachinko gaming machines provided with an open / close-type start opening, a gate, and an open / close-type large winning opening.
