Description

  The present invention relates to a gaming machine represented by a pachinko gaming machine.

  As a representative example of this type of gaming machine, a game ball is launched into a game area of a game board by a player operating a launch handle, and a game is repeated while repeatedly colliding with a number of game nails implanted in the game area. There is known a pachinko gaming machine in which a winning ball is acquired by causing a winning ball provided in the gaming area to win a prize ball while rolling down the ball.

  Conventional pachinko machines have been provided with a plurality of types of winning areas (so-called “winning mouths”) and a display that is a display means for performing a predetermined effect display, which is one of the winning areas. The winning area (so-called “starter”) is provided with a variable member that is normally closed and is opened for a predetermined time so that a game ball can easily enter when a predetermined condition is satisfied.

  Then, when a game ball enters the start opening, a jackpot lottery is performed to determine whether or not to shift from a base game to a jackpot game that is more advantageous to the player than the base game. After a number of symbols fluctuate, effect display using effect images, such as a stop display with a combination according to the result of the jackpot lottery, and a character image etc. are displayed in accordance with the change display of these symbols Is to be done. In addition, the effect display using such effect images changes every time the game state changes, such as the normal game state or the big hit game state.

  When the jackpot lottery is won and the jackpot game is executed, a special game mode in which the variable member repeats the opening / closing operation for a predetermined period (so-called “short time mode”) is executed for a predetermined period in the subsequent normal game. It is common.

  In recent years, in order to provide players with more jackpot lottery opportunities, a gaming machine with a plurality of starting holes in the gaming area has been considered. Problems are likely to occur due to timing.

  In view of this, a gaming machine is provided that displays changes in a plurality of identification information in synchronism when a game ball enters a plurality of starting ports (Patent Document 1). Furthermore, a game machine is provided that continues to fluctuate the identification information at the other start port when the big hit lottery performed when a game ball enters one start port is a win (Patent Literature). 2).

  Further, in recent years, as a jackpot game, a plurality of jackpot games having different degrees of advantage are set at an appropriate distribution rate according to each starting port.

For example,
“Normal jackpot game”: A jackpot game that has a relatively long game execution period and is expected to win a predetermined amount of prize balls, but has a low probability of winning a jackpot lottery in a regular game immediately after the jackpot game ends. ,
“Probability variation jackpot”: The game execution period is relatively long, a predetermined amount of prize balls are expected to be obtained, and the winning probability of the jackpot lottery performed in the normal game immediately after the jackpot game ends is high. The jackpot game that is most advantageous to the player,
“Sudden probability rush-type jackpot”: Although the game execution period is relatively short and the expectation for winning a prize ball is small, the winning probability of the jackpot lottery performed in the normal game immediately after the jackpot game ends is high. Jackpot game,
“Short-time rush-type jackpot”: The short game run period is relatively short, the expectation for winning a prize ball is small, and the normal game immediately after the end of the jackpot game is given a privilege only for the short-time mode. The winning probability of the jackpot lottery to be performed is also a low probability, a jackpot game that is relatively disadvantageous to the player,
and so on.

  In addition, in a gaming machine having a plurality of start openings, for example, a game ball is likely to win in a first start opening arranged so as to mainly win in a normal game state and a normal game immediately after a big hit game. A second start opening provided with a variable member that fluctuates frequently in the open state, and when winning the jackpot lottery performed when winning the second start opening, Some have changed the conditions of the big hit lottery performed for each winning at both start openings, such as lowering the probability that "

In such a game machine, even if a “sudden probability change rush type jackpot” is won in a normal game immediately after the “probability change jackpot” ends, the current state where the winning probability is simply high and the winning probability is not maintained is expected. It is easy to avoid winning a big hit game that is not very meaningful for a player who is only played.

  However, in the gaming machine having two start ports as described above, the jackpot lottery condition setting corresponding to each start port is usually designed to differentiate between the two. For this reason, for example, the first start There is a difference in the winning ball amount between the jackpot lottery result by winning the game ball in the mouth and the jackpot lottery result by winning the game ball in the second starting port, and the player has 2 There was a risk of feeling unfair to the two starters.

  In addition, even if the type of jackpot game is set at an appropriate allocation rate according to each starting port, there is no sufficient basis for the allocation rate so far, so that the jackpot game continues Even if such a case occurs, the types of jackpots are biased, and for this reason, the effect display using images tends to be uniform.

  An object of the present invention is to solve the above-mentioned problems and to provide a gaming machine in which a player can enjoy playing a game without feeling unfair to two starting ports.

(1) In the present invention, a first start winning area in which a variable member that changes to an open state in which a gaming ball is easy to win when a predetermined condition is satisfied is attached to the gaming area in which the gaming ball rolls, A gaming board having a plurality of winning areas including a second starting winning area having a specification different from the first starting winning area; and when a game ball passes through the winning area, a predetermined number of winning balls are paid out; Control the progress of the entire game including a jackpot game in which a game ball is likely to win in a predetermined winning area of the plurality of winning areas and a normal game in which a lottery is performed to determine whether or not to shift to the jackpot game Game progress control means, and when a game ball passes through the first start winning area during execution of the normal game, the first lottery process corresponding to the first start winning area When a game ball passes through the start winning area A jackpot lottery means for performing a second lottery process corresponding to the second starting winning regions, respectively, a plurality of jackpot gaming information execution period are different jackpot game in the first sorting index, the first lottery process The second storage lottery game information is stored in association with each other, and a plurality of jackpot game information with different jackpot game execution periods are used in the second lottery process at a second allocation rate different from the first allocation rate. Out of the jackpot game information in the first storage means in the first lottery process and the second storage means stored in association, the jackpot game information in the second storage means in the second lottery process Jackpot game execution means for selecting jackpot game information from the above and executing a jackpot game based on the selected jackpot game information, and only relative to the first storage means The short execution period of jackpot gaming, and winning probability by the jackpot lottery means is usually performed game immediately after the end of the jackpot gaming has certain bonus game information at a low probability are stored in the first storage unit The expected value of the jackpot game execution period based on the execution period of the jackpot game corresponding to each of the plurality of jackpot game information stored and the first distribution rate, and a plurality of values stored in the second storage means The jackpot game executed on the basis of the first lottery process is equal to the expected value of the jackpot game execution period based on the jackpot game execution period corresponding to each of the jackpot game information and the second allocation rate. In the normal game immediately after the end, the probability that the winning probability by the jackpot lottery means becomes high and the large number executed based on the second lottery process In a normal game immediately after the winning game, the gaming machine has the same probability that the winning probability by the jackpot lottery means is high .

In addition , the game progress control means may perform the normal game for any period of time in a special game mode in which the variation mode of the variable member attached to the first start winning area is advantageous to the player for a predetermined period. However, the game can be executed in any one of the normal game modes that are relatively disadvantageous to the player, and immediately after the jackpot game is over, the game can be shifted to the normal game in the special game mode.

Further , as the plurality of jackpot game information respectively stored in the first storage means and the second storage means, the game is executed in a normal game immediately after the jackpot game ends, although the game execution period is relatively short. There is a sudden probability variation rush type jackpot game information in which the winning probability of the jackpot lottery is high, and the allocation ratio of the sudden probability variation rush type jackpot game information is the first storage means and the second storage means in can also Rukoto made different from each other.

Further , only the second storage means stores normal jackpot game information in which the game execution period is relatively long and the winning probability of the jackpot lottery performed in the normal game immediately after the end of the jackpot game is low. It can also be made .

Further , as the jackpot game information, (a) probability variation jackpot game information in which the game execution period is relatively long and the winning probability of the jackpot lottery performed in a normal game immediately after the jackpot game ends is high, b) Although the execution period of the game is relatively short, sudden probability variation rush type jackpot game information in which the winning probability of the jackpot lottery performed in the normal game immediately after the end of the jackpot game is high, (c) relatively Normal jackpot game information in which the game execution period is long and the winning probability of the jackpot lottery performed in the normal game immediately after the end of the jackpot game is low, (d) the game execution period is relatively short and the jackpot The specific jackpot game information is set such that the winning probability of the jackpot lottery performed in the normal game immediately after the game ends is low, and the first storage means The (a) probability variation jackpot game information is 70/100, the (b) sudden probability variation rush type jackpot game information is 15/100, and the (d) specific jackpot game information is 15/100. In the second storage means, (a) the probability variation jackpot game information is 55/100, (b) the sudden probability variation rush type jackpot game information is 30/100, and (c) the normal jackpot game information is 15 Each of them can be stored at a distribution rate of / 100.

In addition , the first start winning area provided with the variable member may be disposed immediately below the second start winning area.

According to the present invention, in the jackpot game won in the lottery process performed by the game ball passing through either the first start prize area or the second start prize area, any start prize area is related. Even if there is, the expected value of the execution period of the jackpot game and the probability that the winning probability of the jackpot lottery performed in the normal game immediately after the end of each jackpot game is equal, the player will However, it is possible to provide a gaming machine in which the expected value of the winning ball amount is the same and does not cause unfair feeling.

  Hereinafter, embodiments of the present invention will be described.

The gaming machine according to the present embodiment includes a first start winning area in which a variable member that changes to an open state in which a gaming ball easily wins when a predetermined condition is satisfied is attached to the gaming area in which the gaming ball rolls. A gaming board having a plurality of winning areas including a second starting winning area having a specification different from the first starting winning area, and a predetermined number of winning balls are paid out when a game ball passes through the winning area In addition, the progress of the entire game including a jackpot game in which a game ball is likely to win in a predetermined winning area of the plurality of winning areas, and a normal game in which a lottery is performed to determine whether or not to shift to the jackpot game A game progression control means for controlling the game, and a first lottery process corresponding to the first start winning area when the game ball passes through the first start winning area during execution of the normal game, A game ball passes through the start winning area of 2 A jackpot lottery means for performing a second lottery process corresponding to the second starting winning regions each case were, a plurality of jackpot gaming information execution period are different jackpot game in the first sorting index, the first A first storage means for storing in association with the lottery process, and a plurality of jackpot game information each having a different jackpot game execution period at a second allocation rate different from the first allocation rate, the second The second storage means for storing in association with the lottery process, and the jackpot game information of the first storage means for the first lottery process, and the second storage means for the second lottery process. Jackpot game execution means for selecting jackpot game information from the jackpot game information and executing the jackpot game based on the selected jackpot game information, the first storage means , Short execution period of relatively jackpot gaming, and the winning probability by the jackpot lottery means is usually performed game immediately after the end of the jackpot gaming has certain bonus game information at a low probability is stored, the first A jackpot game execution period corresponding to each of a plurality of jackpot game information stored in the storage means and an expected value of the jackpot game execution period based on the first allocation rate, and stored in the second storage means The jackpot game execution period corresponding to each of the plurality of jackpot game information is equal to the expected value of the jackpot game execution period based on the second distribution rate, and is executed based on the first lottery process. Based on the probability that the winning probability by the jackpot lottery means becomes high in the normal game immediately after the jackpot game ends, and the second lottery process The probability that the winning probability by the jackpot lottery means becomes a high probability in the normal game immediately after the jackpot game ended is set equal.

  That is, in the game board having a game area in which the game ball rolls in this embodiment, a predetermined number of game balls are paid out to the player as prize balls when the game ball enters (hereinafter referred to as a prize ball). ("Winner") is provided. Of the plurality of winning openings, a first starting winning area (hereinafter referred to as “first starting opening”) provided with a variable member or a second starting winning area (hereinafter referred to as “second”) provided with no variable member. When a game ball enters the starting area), a specific winning area (hereinafter referred to as a “large winning area”) is widely opened to the gaming area from among a plurality of winning areas provided in the gaming area. In normal games, lottery of whether to shift to jackpot game that can provide a predetermined number of prize balls to the player in a short time by making it easy to enter game balls that have rolled down the area Is doing. And a game progress control means for controlling the progress of the entire game, including a jackpot game, a normal game for performing a lottery transition to the jackpot game, and a payout of a prize ball for a game ball entering a plurality of winning holes I have.

  Further, in the present embodiment, when the game ball passes through the first starting port during the normal game, the first lottery process corresponding to the first starting port passes, and the game ball passes through the second starting port. In such a case, there is provided a jackpot lottery means for performing a second lottery process corresponding to the second start port.

  Here, in the jackpot game, a plurality of types of jackpot games having different degrees of advantage for the player are set. That is, when the lottery result of the jackpot lottery means wins a jackpot game, a specific winning area (hereinafter referred to as a big prize opening) is widely opened to the gaming area, and the game balls that have rolled down the gaming area By making it easy to enter the ball, a predetermined number of prize balls are provided to the player in a short time, but by changing the opening period of the big prize opening (that is, the execution period of the jackpot game) By making a difference in the number of prize balls that can be acquired by the player, a plurality of types of jackpot games having different degrees of advantage for the player are obtained.

  More specifically, in the execution of the jackpot game in the present embodiment, after opening the grand prize opening so that a game ball can enter the game area, a predetermined condition (opening time of the big prize opening (for example, 30 Seconds), when a predetermined number (for example, 10) of the game balls are entered into the big winning opening), the opened big winning opening is temporarily closed. Then, the operation from the opening of the big prize opening to the closing is regarded as one round game, and the round game is repeated a predetermined number of times to execute the jackpot game.

  And in this embodiment, the execution period of a jackpot game is made different by setting a plurality of jackpot games having different numbers of executions of the round game. For example, a jackpot game with 15 round games executed has a relatively large number of round games executed compared to a jackpot game with two round games executed. Since the time for digesting the jackpot game becomes longer, the duration of the jackpot game differs depending on the set number of round games to be executed.

  Further, in the jackpot game having different numbers of round games, for example, the opening times of the big winning openings in the round game can be varied. For example, when the number of round game executions is 15, the opening time of the grand prize opening is set to 30 seconds, while when the number of executions of the round game is 2, the opening time of the big prize opening is 0.3. Set to seconds. In other words, a jackpot game with a long opening time of the big winning opening can be expected to enter the big winning opening of the game ball rolling down the game area, while, on the other hand, a big hit game with a short opening time of the big winning opening, I can hardly expect a game ball to enter. Thereby, it is possible to set a jackpot game that greatly differs in the degree of advantage for the player, with a large difference in the number of prize balls that the player can acquire.

  Further, in the present embodiment, not only the number of round games and the opening time of the big prize opening at the time of jackpot game execution are different, but in the normal game after the jackpot game is ended, for example, the jackpot game by the jackpot lottery means The jackpot game in which the lottery probability is set to a high probability (so-called “probability fluctuation”), or the variation mode of the variable member attached to the first start opening is advantageous to the player for a predetermined period after the jackpot game ends. Depending on the jackpot game or the like in which a special game mode (so-called “short-time mode”) that is in a variable state is set, a plurality of jackpot games having different degrees of advantage for the player are set.

  Then, the plurality of jackpot games in the present embodiment increase the conditions for executing the jackpot game (that is, the number of round games executed or the opening time of the jackpot), and the jackpot lottery condition in the normal game after the jackpot game ends. Depending on the probability set (hereinafter referred to as “probability change”) or the special game mode (hereinafter referred to as “short-time mode”), for example, the number of round games executed is 15 times, and the opening time of the big prize opening is normal time (That is, 30 seconds), and after the jackpot game is over, the jackpot game for which the probability variation is set is “15R probability variation jackpot game”, the number of round games executed and the opening time of the prize winning opening is “15R probability variation jackpot game” ”, But the probability variation is not set after the jackpot game ends, that is, it is compared with the high probability set by the probability variation. The jackpot game with the normal probability that can be said to be relatively low is “15R regular jackpot game”, the round game is executed twice and the opening time of the big prize opening is set to a short time (eg, 0.3 seconds) The jackpot game for which probability variation is set after the end of the jackpot game is “2R probability variation jackpot game”, and the number of round games executed and the opening time of the big prize opening are the same as “2R probability variation jackpot game” After the end of the jackpot game, the probability variation is not set (that is, the normal probability), and the jackpot game is distinguished as “2R normal jackpot game”.

  In the above “2R probability variation jackpot game” and “2R normal jackpot game”, the opening time of the big prize opening is set to a short time (for example, 0.3 seconds), and the player wins during the jackpot game. Since the number of winning balls that can be expected can hardly be expected and the execution time of the jackpot game will be completed in a very short time, the player will have the impression that the game mode in normal games will change suddenly without executing the jackpot game. Therefore, “2R probable big hit game” is called “2R sudden probable big hit game (so-called sudden big hit game)”, and “2R normal jackpot game” is called “2R sudden short jackpot game” or “surprise big hit game”. There is a case.

  In the present embodiment, a plurality of jackpot games having different player advantages described above are set with a predetermined distribution rate in each of the first lottery process and the second lottery process, Stored as jackpot game information in the storage means and the second storage means, and from the jackpot game information stored in the first storage means in the first lottery process, the second storage means in the second lottery process The jackpot game to be executed is determined by selecting from the jackpot game information stored in the box according to a predetermined distribution rate.

  In the gaming machine configured as described above, in the present embodiment, only in the first storage means, the execution period of the jackpot game is relatively short compared to other jackpot games, and immediately after the jackpot game ends. In the normal game, the winning probability by the jackpot game lottery means is low (that is, the probability variation that is advantageous to the player is not set, so the jackpot game lottery probability is relatively low) (Probability) specific jackpot game information is stored.

  This specific jackpot game information is equivalent to the above-mentioned “sudden jackpot game”, and it is not possible to expect a prize ball that a player can acquire when the jackpot game is executed, and the short-time mode is set after the jackpot game ends. Although it is set, the jackpot game lottery probability is not set to a high probability like the probability variation, that is, the jackpot game with the lowest degree of advantage for the player among multiple jackpot games due to the normal probability It can be said. In the present embodiment, since the “sudden jackpot game” information is set only in the jackpot game information of the first storage means, the first lottery process is executed in the jackpot lottery means. In this case, there is a possibility that the “sudden hit game” will be executed.

  However, in the present embodiment, in the first storage unit and the second storage unit configured as described above, the predetermined allocation rate for the plurality of jackpot games as the set jackpot game information is finally the first The storage means and the second storage means are configured such that there is no difference in the degree of advantage for the player. Specifically, in the jackpot lottery means, in the jackpot game distributed based on the first storage means and the jackpot game distributed based on the second storage means, as a result, the average number of round games executed The difference between the value and the expected value (that is, the entry rate to the probability fluctuation) set for the probability fluctuation after the jackpot game is finished is made different.

  According to the first storage means and the second storage means as described above, a pachinko gaming machine provided with a plurality of start ports (first start port and second start port) that trigger the big hit lottery in the game area. In addition, by setting different predetermined allocation rates for a plurality of jackpot games, it is possible to characterize the occurrence of jackpot games triggered by each starting port, and any starting port Even in the jackpot game with the opportunity, the degree of advantage for the player can be made equal, so a balanced gaming machine is provided in which the player is less likely to be dissatisfied with the occurrence of a jackpot game according to different starting points. I can do things.

  In addition, the game progress control means may perform the normal game for any period of time in a special game mode in which the variation mode of the variable member attached to the first start winning area is advantageous to the player for a predetermined period. However, the game is executed under any one of the normal game modes that are relatively disadvantageous to the player, and immediately after the jackpot game is finished, control is performed to shift to the normal game in the special game mode; Become.

  That is, in the normal game after the end of the jackpot game, the special game mode (that is, the time reduction mode) in which the opening time and the opening frequency of the variable member attached to the first starting port is improved is executed for a predetermined period. In the plurality of jackpot games in the present embodiment, the game progress control means sets the normal game after the completion of all jackpot games as a special game mode (that is, a time reduction mode).

  Here, the special game mode (hereinafter referred to as the time saving mode) will be described in detail. In the present embodiment, a predetermined condition (a game ball passes through a special area provided in the game area) is used as a trigger. When the open lottery of the variable member attached to the first start opening is performed and the open lottery is won, the variable member is opened to make it easy to enter the game ball into the first start opening. And, for example, when the normal game mode is set in the normal game, the opening time of the variable member is set to 0.1 second and the release frequency is set to once every 30 seconds, whereas the time reduction mode is set. In this case, the opening time of the variable member is set to 3 seconds and the opening frequency is set to once every 10 seconds.

  That is, when the normal game is set to the short-time mode, the opening time of the variable member attached to the first starting port is long and the opening frequency is high, so that the game ball enters the first starting port. The rate is improved. In addition, the number of lotteries by the jackpot lottery means triggered by the first starting port increases, and the number of prize balls according to the number of game balls entered can be expected, so that the game conditions have a higher degree of advantage than the normal mode for the player. It can be said.

  In other words, in the normal game after the end of the jackpot game, even if the probability variation with a high degree of advantage of the player is not set, the game state with a slightly high degree of advantage of the player can be achieved by adding the short-time mode. It is provided to the person. In this time-saving mode, the operation period may be determined in advance. For example, when a predetermined number of lotteries (for example, 100 times) is executed by the jackpot game lottery means, the time-saving mode in the normal game ends and the normal mode Will be set.

  In addition, the short-time mode and the probability variation may be set in combination. For example, after the completion of “15R probability variation big hit game” or “2R probability variation big hit game”, the short time mode and probability variation are set together. The In this case, the operation mode of the short-time mode is set until the next jackpot game is won, or the number of lotteries by the jackpot game lottery means sufficient to win the next jackpot game (for example, 10,000 times) May be set.

  In the present embodiment, as the plurality of jackpot game information respectively stored in the first storage means and the second storage means, although the execution period of the game is relatively short, the end of the jackpot game There is sudden probability variation rush type jackpot game information in which the winning probability of the jackpot lottery performed in the normal game immediately after is high, and the distribution ratio of the sudden probability variation rush type jackpot game information is set as the first storage means and the Different from the second storage means.

  This sudden probability variation rush type jackpot game information corresponds to the above-mentioned “2R probability variation jackpot game”, and the impression that the probability variation is suddenly set in the game mode in the normal game without executing the jackpot game. This is a jackpot game called “2R sudden probability change jackpot game” because it is given to the player, and hereinafter referred to as “sudden probability change jackpot game” or “surprise jackpot game”.

  That is, in this embodiment, when winning a jackpot game by the jackpot lottery means and distributing to a single jackpot game from a plurality of jackpot games, the case based on the first storage means and the second storage means In the case of being based, the rate of distribution to “surprising big hit game” is different. More specifically, for example, the first storage unit and the second storage unit are distributed at a rate of 30% when based on the first storage unit and at a rate of 15% when based on the second storage unit. The jackpot game information stored in the storage means is set.

  As a result, it is possible to vary the occurrence ratio of the jackpot game by the jackpot lottery means between the first storage means corresponding to the first start port and the second storage means corresponding to the second start port. According to each of a plurality of start ports that become the trigger of the game machine, it can be a gaming machine having a different rate of occurrence of “surprising big hit game”.

  Further, only the second storage means stores normal jackpot game information in which the game execution period is relatively long and the winning probability of the jackpot lottery performed in the normal game immediately after the end of the jackpot game is low. It is characterized by being.

  The normal jackpot game information corresponds to the “15R normal jackpot game”, and as described above, the “15R normal jackpot game” is a jackpot game that allows a player to win a predetermined number of prize balls. After the jackpot game, the short time mode in which the operation period is determined without setting the probability variation is set. In the present embodiment, the ratio to be distributed to the “15R normal jackpot game” is set in the jackpot game information stored in the second storage means.

  As a result, the game machine in which “15R normal jackpot game” is generated only in the jackpot lottery using the second storage means by the jackpot lottery means triggered by the game ball entering the second starting port. Therefore, in the jackpot game that is distributed by using a plurality of start ports (first start port and second start port) from among the plurality of jackpot games in the present embodiment, the jackpot game that can be won for each start port Can be differentiated.

  Summarizing the jackpot game information described above, in this embodiment, (a) the game execution period is relatively long, and the winning probability of the jackpot lottery performed in the normal game immediately after the jackpot game ends is high. Probability variation jackpot game information, (b) Sudden probability variation rush type jackpot game information with a high probability of winning the jackpot lottery performed in the normal game immediately after the end of the jackpot game, although the game execution period is relatively short (C) Normal jackpot game information in which the game execution period is relatively long and the winning probability of the jackpot lottery performed in the normal game immediately after the end of the jackpot game is low, (d) The specific jackpot game information is set such that the execution period is short and the winning probability of the jackpot lottery performed in the normal game immediately after the jackpot game ends is low. It has been. Further, in the first storage means, (a) probability variation jackpot game information is 70/100, (b) sudden probability variation rush type jackpot game information is 15/100, and (d) specific jackpot game information. Is a distribution rate of 15/100, and the second storage means stores (a) probability variation jackpot game information 55/100, (b) the sudden probability variation rush type jackpot game information 30/100, (C) Normal jackpot game information is stored at a distribution rate of 15/100, respectively.

  That is, as described above, the jackpot game related to the information in (a) is “15R probability variable jackpot game”, the jackpot game related to the information in (b) is “surprising jackpot game”, and (c) The jackpot game related to information corresponds to “15R normal jackpot game”, and the jackpot game related to information (d) above corresponds to “accidental jackpot game”. In this embodiment, the above four types of players The jackpot games having different degrees of advantage are stored as jackpot game information in the first storage means and the second storage means.

  In the first storage means, information on (a) “15R probable big hit game” is 70/100, (b) information on “surprise big hit game” is 15/100, and (d) “crash big hit game” Is stored as jackpot game information at a distribution rate of 15/100, and the second storage means stores information on (a) “15R probability variable jackpot game” 55/100, (b) “surprise jackpot game” "30/100" and (c) "15R normal jackpot game" information is stored as jackpot game information at a distribution rate of 15/100.

  In the distribution of the jackpot game information by the first storage means and the second storage means as described above, the first storage means does not have the second storage means. (C) “15R normal jackpot game” is stored in the second storage means, which is not in the first storage means. Therefore, in this embodiment, a game ball is sent to the first starting port. When a ball enters the ball, there is a possibility that a “striking jackpot game” may occur. On the other hand, when a game ball enters the second starting port, a “15R normal jackpot game” may occur. Differentiate each starting point.

  However, in the present embodiment, the jackpot game information stored in the first storage means and the second storage means is set for differentiation by setting a specific jackpot game in accordance with each of the plurality of start ports. In the first storage means and the second storage means, the first storage means and the second storage means are the same when compared with the expected value of the number of round games executed for each of the first storage means and the second storage means and the expected value in which the probability variation is set. Expected value is set.

  More specifically, when comparing the expected value of the number of executions of the round game, in the first storage means, 15 round games are 70/100 as “15R probable big hit games”, and 2 round games are “ The sum of 15/100 of “Successful jackpot game” and 15/100 of “Sudden jackpot game” is 30/100. On the other hand, in the second storage means, the 15 round games have a total of 70/100, 2 times of 55/100 of “15R probability variable jackpot game” and 15/100 of “15R normal jackpot game”. Since the round game of 30 is 100/100 as “surprising big hit game”, the distribution rate of 15 round games is the same as 70/100, and the distribution rate of 2 round games is also the same as 30/100 Therefore, the same value is set as the expected value of the number of executions of the round game in the first storage unit and the second storage unit.

  In other words, regardless of whether the first storage means or the second storage means is used by the jackpot lottery means of this embodiment, the probability of being distributed to the jackpot game having 15 round games is 70%. Yes, it can be said that the probability of being distributed to the jackpot game with two round games is 30%.

  Further, when comparing the expected value in which the probability variation is set, in the first storage means, the distribution rate in which the probability variation is set is 15/100 of the “probable big hit game” and 70/15 of the “15 chance variable big game”. The sum of 100 is 85/100. On the other hand, in the second storage means, the sum of 55/100 of “15-probable big hit game” and 30/100 of “surprise big hit game” is 85/100, so the first storage means and the second storage means Then, the same value (85/100) is set as the expected value for which the probability variation is set. In other words, in this embodiment, the jackpot game in which the probability variation is set at a rate of 85%, even if the winning jackpot game won by any of the first storage means and the second storage means is distributed. Will occur.

  Further, the first start winning area provided with the variable member is disposed at a position immediately below the second starting winning area.

  That is, as described above, the jackpot game lottery that is triggered when the game ball enters the first starting area (that is, the first starting port) to which the variable member is attached, "Game" is included. This “collision jackpot game” has the lowest advantage to the player among the four types of jackpot games in the present embodiment. Therefore, when the player is playing the game machine and the first jackpot game that can be acquired is the “sudden jackpot game”, the short-time mode with a predetermined number of operating periods is only set to the normal game. Therefore, the profit is too small for the player, and there is a possibility that the willingness to continue the game on the gaming machine is attenuated.

  Therefore, in the present embodiment, a game is provided by providing a first start region (that is, the first start port) with a variable member attached below the second start winning region (that is, the second start port). The first jackpot game that can be provided to the player is determined based on the jackpot game information stored in the second storage means such that the second storage means corresponding to the second starting port is determined at a predetermined distribution rate. The winning jackpot game is distributed.

  As a result, there is a high possibility that the first jackpot game that the player can acquire is “15R probability change jackpot game”, “surprising jackpot game” and “15R normal jackpot game”, so at least “15R regular jackpot game” Can win a predetermined number of prize balls in the jackpot game, and in the “promising jackpot game”, it cannot be expected to win a prize ball in the jackpot game, but since the probability variation is set, In the “15R probability variation jackpot game” that can be expected to win and has the highest degree of advantage for the player in the present embodiment, a predetermined number of award balls can be obtained in the jackpot game, and the probability variation is set next time. It can be a jackpot game that is beneficial to any player who can expect to win a jackpot game.

  In the present embodiment, the first starting port is provided with a variable member that improves the opening time and the release frequency in the time reduction mode. Therefore, when the variable member is disposed below the second starting port, the variable member is opened. In such a case, it is possible to install a game ball so that it can be entered. As a result, the lottery of the jackpot game triggered by the first starting port is executed in the time saving mode (which may be set simultaneously with the probability variation) set after the jackpot game is triggered by the second starting port. In this way, while the normal game is set to the normal mode, the possibility that the big hit game that the player can obtain first is the “collision big hit game” can be kept low.

  According to the gaming machine described above, a plurality of start holes (first start port and second start port) are provided in the game area, and the four types of jackpot games described above are provided depending on the start port into which the game ball has entered. It is possible to differentiate a plurality of start ports (first start port and second start port) by giving a characteristic to the distribution ratio of the first and second start ports. It is possible to provide a gaming machine that can generate a plurality of well-balanced jackpot games that do not differ in the player's degree of advantage for a jackpot game that is triggered by either of the above.

  The variable member can be changed by using an operation means such as a solenoid. As the normal game progress means, the big hit lottery means, the first storage means, the second storage means, and the big hit game execution means, a CPU or game The function may be assigned to a control unit having various memories such as a ROM storing programs and a RAM used as temporary storage means for a work area.

A certain number of game balls are paid out as prize balls to the upper plate 20 or the lower plate 22 which are game ball storage units.

  Moreover, the electrical decoration unit 53 is provided in the lower end part vicinity of the door 11a. As shown in FIG. 4, the electrical decoration unit 53 according to the present embodiment has a first special symbol display 33 and a second start opening corresponding to the first start opening 24 in a display case 37 arranged in the center thereof. The second special symbol display 34 corresponding to 25 is accommodated. The first special symbol display 33 and the second special symbol display 34 are composed of 7-segment LEDs, and the 7-segment LEDs have won a game ball in the first start port 24 or the second start port 25. In this case, 10 number symbols from “0” to “9” are specially displayed by turning on / off the 7-segment LED of the corresponding first special symbol display 33 or second special symbol display 34. Fluctuated display as a symbol. As described above, a game in which a special symbol is variably displayed and then stopped and the game state varies depending on the result is referred to as a “special symbol game” in the present embodiment.

  On both the left and right sides of the display case 37, the first special symbol hold lamps 33a to 33d corresponding to the first start port 24 and the second special symbol hold lamp corresponding to the second start port 25 are sandwiched between the display case 37. 34a to 34d are provided. The first special symbol holding lamps 33a to 33d are displayed on the first special symbol display unit 33 when the game ball has won the first start port 24 while the special symbol is already displayed. Until the stop display is made, the number of times that the execution of the special symbol variation display based on the winning of the game ball to the first start opening 24 is suspended (so-called “the number of special symbols held”) is displayed by lighting. . Then, when the special symbol that has been variably displayed is stopped and displayed, variability display of the special symbol that has been suspended is started.

  Similarly to the first special symbol holding lamps 33a to 33d, the second special symbol holding lamps 34a to 34d are displayed in the second special symbol display 34 while the game ball is already in the second start opening during the special symbol variation display. The number of times the execution of the special symbol variation display based on the winning of the game ball to the second starting port 25 is suspended until the special symbol in the variable display is stopped and displayed when the prize is won (so-called “special symbol”). The number of reserved balls of “)” is displayed by lighting. Then, when the special symbol that has been variably displayed is stopped and displayed, variability display of the special symbol that has been suspended is started.

  Specifically, the first special symbol hold lamps 33a to 33d and the second special symbol hold lamps 34a to 34d are lit in order from the left according to the number of times the execution of the special symbol variation display is held, When the change display of the special symbol is stopped and displayed, and the next change display of the special symbol that has been put on hold is started, the special symbol hold lamp corresponding thereto is turned off. An upper limit is set for the number of times the execution of the special symbol variation display is suspended, and four times (pieces) for winning the game ball to the first start port 24, and the second start port 25. The special symbol variation display is put on hold up to 4 times (pieces), that is, a maximum of 8 times (pieces) in the present embodiment for the winning of the game ball.

  Also, in the display area 32a of the liquid crystal display device 32, when a game ball is won in the first starting port 24 and the second starting port 25 described above, for example, a number or the like is displayed at the start of the variable symbol display. The variation display of the decorative pattern for the production including is started. In addition, when the game ball wins the first start opening 24 and the second start opening 25 during the variable display related to the special symbol, the first start opening is displayed until the decorative design for effect during the variable display is stopped and displayed. Execution (start) of the variation display of the decorative pattern for effect based on the winning of the game ball to the 24 and the second start opening 25 is suspended. Thereafter, when the decorative design for effect that has been variably displayed is stopped and displayed, the variable display of the decorative symbol for effect that has been put on hold is started. That is, the decorative display variation display and the special design variation display performed in the display area 32a of the liquid crystal display device 32 are synchronized, and the variation start and variation stop are performed at the same timing. .

  In the present embodiment, both the special symbol and the decorative symbol described above function as identification information, and are executed in synchronization with the special symbol game in which the unit game is from the change display to the stop display of the special symbol, and the special symbol. The game is a “variable display game” in combination with a game in which the unit game is displayed from the change display of the decorative symbols to the stop display. Therefore, in the pachinko gaming machine 10 according to the present embodiment, a variable display game is played when a game ball wins a prize at the first start port 24 and the second start port 25. A game in which this variable display game is played is called a normal game.

  Further, when the game ball passes through the passing gate 54 (see FIG. 3) provided on the left side of the approximate center of the game area 15, the normal symbol display 35 provided on the right side of the second special symbol display 34 Two display lamps composed of symbols such as “◯” and “x” indicating symbols are variably displayed by alternately turning on and off.

  Further, below the display case 37, normal symbol holding lamps 35a to 35d are provided. The normal symbol holding lamps 35a to 35d are turned on or turned off when the game ball passes through the passing gate 54 during the fluctuation of the above-described normal symbols (in this embodiment, symbols such as “O”, “X”). By turning off the light, the number of times that the fluctuation display of the normal symbol being held can be executed (so-called “the number of balls held in the normal symbol”) is displayed. That is, the normal symbol hold lamps 35a to 35d are turned on sequentially from the left in accordance with the number of executions of the fluctuation display of the held normal symbols, and when the fluctuation is stopped and displayed, the next normal symbol that has been held is held. Is displayed, and the corresponding normal symbol holding lamp is turned off. Note that an upper limit is set for the number of times that the execution of the variable symbol display is suspended. For example, the upper limit is four times (pieces).

  When this normal symbol is stopped and displayed as a predetermined symbol, for example, “◯”, the blade members (so-called “normal electric accessories”) 23 provided as variable members on the left and right sides of the first start port 24 are closed. The game ball easily enters the first start port 24 by changing from the open state to the open state. Further, when a predetermined time has elapsed after the blade member 23 is in the open state, the blade member 23 is closed so that it is difficult for the game ball to enter the first start port 24. As described above, a game in which the normal symbol is displayed in a variable manner and then stopped and the open / closed state of the blade member 23 differs depending on the result is referred to as a “normal symbol game”.

  As described above, in the pachinko gaming machine 10 according to the present embodiment, whether or not to shift to the jackpot game is triggered by the winning of the game ball to the first start port 24 and the second start port 25. A lottery process is performed, and based on the lottery result, the first special symbol display 33 and the second special symbol display 34 display the variation and stop display of the special symbol.

  Then, in the display area 32a of the liquid crystal display device 32, a variable display game is executed in which a plurality of decorative symbols as identification information corresponding to the special symbols to be stopped are displayed in a variable manner and then stopped in a predetermined combination. At the same time, an effect display using an effect image associated with the variable display game is performed. When the lottery result of the jackpot game is a win, the game shifts from the normal game to the jackpot game.

  In this configuration, in the present embodiment, the first lottery process is executed when the first start port 24 is won, and the second lottery process is executed when the second start port 25 is won. That is, in the jackpot lottery means triggered by the winning of game balls to the first start port 24 and the second start port 25, the jackpot game lottery process is independently executed in accordance with each start port.

  Specifically, out of a plurality of jackpot games in the present embodiment, in the first lottery process, the jackpot game is determined based on the jackpot game information stored in the first storage means. In the lottery process, the jackpot game is determined based on the jackpot game information stored in the second storage means. That is, in the first start port 24 and the second start port 25, a plurality of jackpot games are determined at different distribution rates based on the jackpot game information stored in the first storage unit and the second storage unit. Differentiate the jackpot lottery.

  As described above, in the present embodiment, a different jackpot game distribution rate is set for each of the plurality of start ports (that is, the first start port 24 and the second start port 25) to provide characteristics. However, as a result, the first starter 24 and the second starter 25 store the first storage unit and the second storage unit so that the degree of advantage for the player does not differ depending on the generated jackpot game. The jackpot game information that is set. The setting of jackpot game information and the configuration of a plurality of jackpot games in this embodiment will be described in detail later.

  Here, in the present embodiment, as an example of an accessory, an accessory of the big prize opening 39 used at the time of the big hit game is described, but the present invention is not limited to this, and two or more on the game board are described. Any number of objects may be provided.

The game board 14 is sequentially fired by the solenoid.

  On the other hand, the sub-control circuit 200 is connected to the serial communication IC 72. The sub-control circuit 200 performs display control in the liquid crystal display device 32, control related to sound generated from the speakers 46R and 46L, control of the decoration lamps 133a and 133b, and the like in accordance with various commands supplied from the main control circuit 60.

[Game machine operation]
Here, the game of the pachinko gaming machine 10 in this embodiment will be briefly described. In the present embodiment, the games of the pachinko gaming machine 10 are roughly divided into normal games (games that consume game balls while performing a big hit lottery and are relatively disadvantageous to the player as compared to the big hit games). The game is divided into jackpot games (games that are advantageous for the player who can expect to acquire a large number of game balls in a short time for the player).

  Furthermore, in the jackpot game, a 15R probability variable jackpot game is drawn by a specific number symbol that is stopped and displayed on the first special symbol display 33 or the second special symbol display 34, which is selected in the special symbol control process described later. The four types of jackpot games are determined, that is, a sudden jackpot game, a sudden jackpot game, or a 15R regular jackpot game.

  The four types of jackpot games (15R-probable jackpot game, surprise jackpot game, sudden jackpot game or 15R normal jackpot game) are processed in the special symbol memory check process (see FIG. 10) described later (see FIG. 6). Referring to), lotteries are drawn with different drawing probabilities according to the normal mode or the probability variation mode of the normal game.

  At this time, when the jackpot game is won, the special symbol stopped and displayed on the first special symbol display 33 and the second special symbol display 34 (see FIG. 4) is, for example, “7” in the case of 15R probability variable jackpot game. “3” special symbols, “1” special symbols for sudden jackpot games, and “5” special symbols for 15R regular jackpot games. The

  Furthermore, when one of the four types of jackpot games is won, the special symbol is stopped and displayed on the first special symbol display 33 or the second special symbol display 34 (see FIG. 4). At the same timing, in the display area 32a of the liquid crystal display device 32, for example, in the case of a 15R probability variable big hit game, a decorative pattern of “777”, a sudden hit big game, by a special decorative symbol (that is, a numeric symbol as identification information). In the case of “3”, a decorative symbol “333” is displayed, in the case of a sudden jackpot game, a decorative symbol “111” is displayed, and in the case of a 15R normal jackpot game, a decorative symbol “555” is displayed.

  It should be noted that the decorative symbols (numeric symbols as identification information) displayed in the display area 32a of the liquid crystal display device 32 when winning the jackpot game need not necessarily be a set of three numeric symbols as described above. For example, in the case of a big hit game, a continuous numerical symbol such as “123” may be used.

  Among the four types of jackpot games, in the 15R probability variation jackpot game and the 15R normal jackpot game, the shutter 40 (see FIG. 3) attached to the prize winning port 39 is held for a predetermined time (for example, 30 seconds). ) Is repeatedly released, it becomes easy to win the game ball fired in the game area 15 to the big winning opening 39, and the player can acquire a large amount of prize balls in a short time. Acquiring such a jackpot game (winning the jackpot game) is the greatest goal of general players, and can be said to be the best part of a pachinko game.

  In the present embodiment, among the four types of jackpot games, when the winning jackpot game or the sudden jackpot game is won, the opening time of the shutter 40 (see FIG. 3) attached to the prize winning port 39 is Since it is set to an extremely short time (for example, 0.3 seconds), in this case, it is difficult to win the game ball fired in the game area 15 to the big winning opening 39, and the prize at the time of execution of the jackpot game I can hardly get the ball.

  On the other hand, the normal game in the present embodiment is executed under three types of game modes: a normal mode, a probability change mode, and a time reduction mode (special game mode). Here, the mode transition of each of the three types of normal games (the normal mode, the probability variation mode, and the time reduction mode) and their characteristics will be briefly described below.

  The normal mode is a basic mode in the pachinko gaming machine 10, and when the power is turned on to the pachinko gaming machine 10, the game is started from the normal mode, and the lottery probability of the big hit game is also drawn by the normal probability. Note that the lottery probability of the jackpot game in the normal mode (that is, the normal probability) is set to a relatively low probability compared with the lottery probability of the jackpot game in the probability variation mode, so the lottery probability of the jackpot game in the normal mode A normal probability that is sometimes referred to as a low probability.

  The probability change mode is a game mode that shifts after the jackpot game ends when a 15R probability change jackpot game or a surprise jackpot game among the four types of jackpot games is won in the normal game. This means that the jackpot lottery probability in the probability variation mode is set to be higher than the jackpot lottery probability in the mode. Specifically, in this embodiment, the jackpot lottery probability in the normal mode is “1/400”, whereas the jackpot lottery probability in the probability variation mode is “1/40”, which is 10 times the lottery. The probability is set (see FIG. 6, jackpot lottery table).

  In other words, in the probability variation mode, a jackpot game is generated 10 times more frequently than in the normal mode, which is an advantageous gaming state for the player. In particular, the 15R probability variation jackpot game has a maximum of 15 round games. This is the most advantageous game because it is continued. On the other hand, there are only two round games in the surprise jackpot game, and the duration of the jackpot game is the shortest game in the jackpot game, so when the normal game after the hit game is in the probability change mode However, it cannot be said that the player is a favorable jackpot game as compared to the 15R probability variable jackpot game. In other words, in the surprise jackpot game in the present embodiment, it is almost impossible to expect a winning ball that a player can acquire when the jackpot game is executed, but the normal game is set to a probability change mode (so-called probability fluctuation) after the jackpot game is finished. It is a jackpot game.

  Finally, the time-saving mode (special game mode) is a game mode that is set after the jackpot game is ended, regardless of which of the four types of jackpot games is won. In this normal game, the time-saving mode means that the variation time from the start of the special symbol and the normal symbol to the time when the special symbol and the normal symbol are stopped is set to be shorter than that of the normal mode. In the case of “winning” (that is, when the display lamp is stopped and displayed as “O” in the normal symbol display 35 (see FIG. 4)), the blade member 23 attached to the first start port 24 is opened. The time is set longer than in the normal mode. Such control may be referred to as “electric chew support” in the present embodiment.

  As described above, when “electric chew support” is executed, it becomes easy for a game ball to win the first start opening 24, so that the number of lottery wins per unit time is significantly increased as compared to the normal mode, and the first Since the payout of prize balls for winning at the start opening 24 also increases, there is little loss of game balls (so-called “ball holding” is good), and it can be said that this is an advantageous state for the player.

  In this short-time mode, the duration is determined corresponding to the four types of jackpot games. For example, in the case of a 15R normal jackpot game or a sudden jackpot game, a special symbol is displayed after the jackpot game ends. The number of fluctuations (for example, 100 times) is set as the duration. On the other hand, if the jackpot game is a 15R-probable jackpot game or a promising jackpot game, the duration of the special symbol that can be expected to win the next jackpot game substantially after the jackpot game ends (for example, 10,000 times) Set to

  As described above, in the present embodiment, the normal game is performed under the four game modes of “normal mode”, “probability change mode”, “normal mode + time reduction mode”, and “probability change mode + time reduction mode”. In other words, the gaming state changes according to the change in the gaming state of the pachinko gaming machine 10 (that is, the occurrence of the four types of jackpot games).

  Further, in the present embodiment, although details will be described later, a big hit lottery process for determining whether or not to shift to the big win game is performed when a game ball wins the first start port 24 or the second start port 25. In this case, the first lottery process is executed when a game ball wins at the first start port 24, and the second lottery process is executed when a game ball wins at the second start port 25. In the first lottery process and the second lottery process, the distribution rates of the four types of jackpot games are different.

  That is, when a game ball wins at the first start port 24 or the second start port 25, a jackpot lottery table (see FIG. 6) corresponding to each start port is provided, and the four types of jackpot games (15R probability change) are provided. By differentiating the distribution ratio to the jackpot game, the sudden jackpot game, the sudden jackpot game, and the 15R regular jackpot game), the first start port 24 and the second start port 25 are differentiated.

  Furthermore, in this embodiment, as shown in the jackpot lottery table (see FIG. 6), a specific jackpot game is selected from the four types of jackpot games according to the first start port 24 and the second start port 25. It is configured to be distributed. That is, when the first start port 24 is used as an opportunity, a sudden jackpot game can be won, and when the second start port 25 is used as a trigger, 15R normal jackpot game can be selected. The mouth 25 is characterized.

  Hereinafter, processing executed in the pachinko gaming machine 10 in accordance with the change in the gaming state described above is shown in FIGS.

[Main processing]
As shown in FIG. 7, first, the main CPU 66 of the main control circuit 60 executes initial setting processing such as RAM access permission, backup restoration processing, and work area initialization (step S11). As will be described in detail later with reference to FIG. 9, the progress of the special symbol game, the special symbols displayed on the first special symbol display 33 and the second special symbol display 34, respectively, and the decorative symbols on the liquid crystal display device 32 are provided. A special symbol control process related to the effect display is executed (step S12). Then, as will be described in detail later with reference to FIG. 11, the normal symbol control process relating to the progress of the normal symbol game and the normal symbol displayed on the normal symbol display 35 is executed (step S13). Thus, in the main process, after the initial setting process in step S11 is completed, the processes in step S12 and step S13 are repeatedly executed.

[System timer interrupt processing]
Further, the main CPU 66 may interrupt the main process and execute the system timer interrupt process even when the main process is being executed. The following system timer interrupt process is executed in response to a clock pulse generated from the reset clock pulse generation circuit 62 every predetermined period (for example, 2 milliseconds). This system timer interrupt process will be described with reference to FIG.

  As shown in FIG. 8, first, the main CPU 66 executes a random number update process for updating each lottery value such as a jackpot lottery random value (step S21). Then, the main CPU 66 executes an input detection process for detecting a winning of a game ball to the first start port 24, the second start port 25, etc. (step S22). In this processing, the main CPU 66 stores in the predetermined area of the main RAM 70 data for paying out the game balls (winning the game balls) on the condition that the game balls have won the various winning ports.

  Further, in this input detection process (step S22), when the main CPU 66 detects a winning of a game ball to the first start port 24 or the second start port 25, the random number updated in the random number update process (step S21). The numerical value is read out and stored in a predetermined area of the main RAM 70 with a maximum of four as the upper limit of the number of reservations for each first start port 24 or second start port 25. Then, the winning and the random number value of the game ball to the first start port 24 or the second start port 25 stored in a predetermined area of the main RAM 70 here are the special symbol storage check process (see FIG. 10) described later. It will be referred to in the jackpot lottery process (step S64). When this process ends, the process moves to a step S23.

  In step S23, timer update processing is executed. In this process, the main CPU 66 is a waiting time timer for synchronizing the main control circuit 60 and the sub control circuit 200, and a large time for measuring the opening time of the big winning opening 39 that is opened when a big hit game is generated. Update processing of various timers such as a prize opening timer. Then, when this process ends, the process proceeds to step S24.

  In step S24, an output process is executed. In this process, the main CPU 66 supplies a signal for drive control based on various output requests stored in a predetermined area of the main RAM 70 to a solenoid, a motor, and the like. That is, in each process described later, the main CPU 66 outputs signals to various driving game members (game members that are arranged in the game area 15 of the pachinko gaming machine 10 and change their forms according to the game state). When the request is stored in a predetermined area of the main RAM 70, a signal corresponding to the request is output. For example, the ordinary electric accessory solenoid 118 for opening or closing the blade member 23 attached to the first start opening 24, or the big winning opening for opening or closing the shutter 40 attached to the big winning opening 39. When there is a drive request for each solenoid such as the solenoid 120, a control signal is output to perform a process of driving various drive game members.

  Further, in this output process, the main CPU 66 displays various indicators (a first special symbol display 33 corresponding to the first start port 24, a second start port) installed in the illumination unit 53 (see FIG. 4). 25, a second special symbol display 34 corresponding to 25, a normal symbol display 35, first special symbol holding lamps 33a to 33d corresponding to the first starting port 24, and a second special symbol holding lamp corresponding to the second starting port 25. 34a to 34d and normal symbol hold lamps 35a to 35d), corresponding to the change request or stop request of lamps, or the lamp turn-on request or turn-off request stored in a predetermined area of the main RAM 70, respectively. It controls the change or stop of the symbols, or the lighting or extinguishing of the lamps of various indicators installed in the lighting unit 53 (see FIG. 4). And when this process is complete | finished, a process is moved to step S25.

  In step S25, command output processing is executed. In this process, the main CPU 66 supplies various command signals to the sub control circuit 200. As these various command signals, for example, in the display area 32a of the liquid crystal display device 32, a demonstration display command that is derived and displayed, and a derived symbol designation that designates the type of decorative symbol for displaying the lottery result by the jackpot lottery means Commands etc. are included. If this process ends, the process moves to a step S26.

  In step S26, the main CPU 66 executes a payout process such as transmitting a prize ball control command signal for causing the payout device 128 to play a prize ball to the payout / firing control circuit 126. Specifically, the main CPU 66 supplies to the payout / launch control circuit 126 a prize ball control command signal for paying out a predetermined number of prize balls as a result of the game balls winning in various winning holes. . When this process is finished, this subroutine is finished, the address is returned to the address before the occurrence of the interrupt, and the main process is executed.

  Here, in the present embodiment, the random number value updated within a predetermined range (for example, 1 to 40000) in the random number update process (step S21) is sent to the first start port 24 or the second start port 25 as a game ball. Is read out at the timing of winning a prize and used as a random value for the big hit lottery. However, the means for acquiring the random number value is not limited to the configuration of the present embodiment. For example, a dedicated random number generator or the like is provided in the main control circuit 60, and within a predetermined range (for example, 1 to 40000). The randomly updated random number value may be read out at the timing when the game ball wins the first starting port 24 or the second starting port 25, and may be used as the random number value for the big hit lottery.

[Special symbol control processing]
The special symbol control process executed in step S12 in FIG. 7 will be described with reference to FIG.

  First, in the process of step S31, the main CPU 66 loads a special symbol control flag. In this process, the main CPU 66 reads the special symbol control flag and moves the process to step S32.

  In step S32, the main CPU 66 determines whether or not the special symbol control flag is (00). If the special symbol control flag is not (00), the main CPU 66 proceeds to step S34. If the special symbol control flag is (00), the process proceeds to step S33 to perform a special symbol storage check process. As will be described in detail later, in this special symbol memory check process, the number of reserved special symbols is checked, and if there is a reserved number, a “big hit” lottery, special symbol variation start, special symbol variation timer is set, etc. Then, (01) which is the processing request for the next step is set in the special symbol control flag, and the processing is terminated.

  In step S34, the main CPU 66 determines whether or not the special symbol control flag is (01). If the special symbol control flag is not (01), the main CPU 66 shifts the processing to step S40. When the special symbol control flag is (01), special symbol variation time monitoring processing is performed. That is, in step S35, it is determined whether or not the special symbol variation timer is up (that is, “0”). If the time is not up, the process is terminated. If the time is up, the main CPU 66 shifts the processing to step S36.

  In step S36, the main CPU 66 performs a special symbol stop process. In this special symbol stop process, the main CPU 66 stores a change stop request for the special symbol being displayed in a predetermined area in the main RAM 70 corresponding to each of the first start port 24 and the second start port 25. . Then, the special symbol fluctuation stop request stored in a predetermined area of the main RAM 70 in this process is the illumination unit 53 (see FIG. 4) in the output process (FIG. 8, step S24) of the system timer interrupt process described above. In response to the first start port 24 and the second start port 25, the special symbols being displayed in a variable manner are variably stopped. When this process ends, the process moves to a step S37.

  Then, the main CPU 66 determines whether or not the special symbol is a big hit in step S37, and if it is not a big win, the main CPU 66 moves the process to step S39. On the other hand, if it is a big hit, a special winning opening release waiting process of step S38 is performed. In the special winning opening release waiting process, the main CPU 66 sets a value (02) indicating waiting for the special winning opening to the special symbol control flag, and sets a waiting time (for example, 1 second) in the special winning opening release waiting timer. This subroutine ends.

  In step S39, the main CPU 66 clears the special symbol control flag (that is, sets a value (00) for requesting the special symbol storage check process), and ends the special symbol control process.

  In step S40, the main CPU 66 determines whether or not the special symbol control flag is (02). If the special symbol control flag is not (02), the process proceeds to step S43. When the special symbol control flag is (02), a special winning opening release process is performed. In the special prize opening process, first, the main CPU 66 determines in step S41 whether the special prize opening waiting timer is timed up (that is, “0”). If the time is not up, the process is terminated. If the time is up, a special winning opening opening process is performed in step S42. In this special winning opening opening process, the main CPU 66 first sets the opening of the special winning opening 39 (stores the opening instruction of the special winning opening solenoid 120 by the shutter 40 in a predetermined area of the main RAM 70), and then the big hit Depending on the type of game, the opening time of the big prize opening 39 in the big prize opening timer (for example, in the case of a surprise jackpot game or a sudden jackpot game, 0.3 seconds, in the case of 15R normal jackpot game or 15R probability jackpot game, 30 seconds) Set. Then, the special symbol control flag is set to a value (03) indicating the special winning opening release monitoring process, and the process ends.

  In step S43, the main CPU 66 determines whether or not the special symbol control flag is (03). If the special symbol control flag is not (03), the process proceeds to step S49. When the special symbol control flag is (03), a special winning opening opening monitoring process is performed. In this special winning opening release monitoring process, first, the main CPU 66 has timed out (that is, “0”) the special winning opening release timer in step S44, or a predetermined number of game balls won the special winning opening 39. Determine whether or not. Then, when the time of the grand prize opening timer expires, and at the same time, if the prescribed number of game balls have not won the grand prize opening 39, the processing is terminated. Then, when the time of the winning opening opening timer expires or when a prescribed number of game balls in the large winning opening 39 satisfy one of the conditions for winning, the process proceeds to step S45.

  In step S45, the main CPU 66 executes a special winning opening closing process (stores a closing instruction of the special winning opening solenoid 120 by the shutter 40 in a predetermined area of the main RAM 70), and moves the process to step S46.

  In step S46, the main CPU 66 counts the number of times of winning the prize winning opening (so-called number of rounds), and the prescribed number of times (15 times for the 15R normal jackpot game or 15R probability variable jackpot game, two times for the sudden jackpot game or the sudden jackpot game). ) Is reached. If the specified number of times has been reached, the special symbol control flag is set to a value (04) for requesting the jackpot end process in step S48, and the process ends. On the other hand, if the number of times of opening the big prize opening has not reached the prescribed number, the main CPU 66 performs a waiting process for waiting for the big prize opening in step S47. In the special winning opening release waiting process, the special symbol control flag is set again with a value (02) for requesting the opening of the special winning opening 39, and the waiting time (for example, 1 second) is set in the special winning opening release waiting timer. Exit.

  In step S49, the main CPU 66 performs jackpot end processing. In the jackpot ending process, when the jackpot symbol is a 15R probability variation jackpot game or a sudden jackpot game, the normal game is set to the “probability variation mode + time reduction mode” and the duration of the time reduction mode is set as the duration of the time reduction mode (for example, 10,000 times) is stored in a predetermined area of the main RAM 70. On the other hand, when the jackpot symbol is a 15R normal jackpot game or a sudden jackpot game, the normal game is set to the “normal mode + short time mode” and a predetermined special symbol variation number (for example, 100 times) is stored in the main RAM 70. Store in a predetermined area. Finally, the main CPU 66 clears the special symbol control flag (that is, sets a value (00) for requesting the special symbol storage check process), and ends the special symbol control process.

[Special symbol memory check processing]
The special symbol memory check process executed in step S33 in FIG. 9 will be described with reference to FIG.

  First, in step S61, the main CPU 66 determines whether or not the number of special symbols held when the game ball is won at the first starting port 24 or the second starting port 25 is “0”. If the number of reserved special symbols is “0”, the process proceeds to step S73. If the number of reserved special symbols is not “0” (that is, if there is a special symbol change request), step S63 is performed. Move processing to.

  In step S73, the main CPU 66 executes a demo display process. In this process, the main CPU 66 sends a demo display command signal to the sub-control circuit 200 in order to perform a demo display. As a result, the sub-control circuit 200 can recognize that the customer waiting state (predetermined waiting state) has been reached. When this process ends, the special symbol storage check process ends.

  In step S63, the main CPU 66 sets a value (01) for requesting special symbol variation time management to the special symbol control flag, and moves the process to step S64.

  In step S64, a jackpot lottery process is executed. In this process, the main CPU 66 determines whether the winning of the game ball that triggers the jackpot lottery is the winning of the starting port of the first starting port 24 or the second starting port 25, and the pachinko gaming machine 10 One jackpot lottery table is selected from a plurality of jackpot lottery tables (see FIG. 6) having different jackpot lottery values based on the current game mode (normal mode, probability change mode). Then, with reference to the jackpot lottery random number extracted when the game ball wins the first start port 24 or the second start port 25 and the selected jackpot lottery table, the lottery of the jackpot game (that is, 15R probability change) The jackpot game, the winning jackpot game, the bonus jackpot game, or the 15R regular jackpot game is selected or “determined”. That is, the first lottery process is performed when a game ball is won at the first start port 24, and the second lottery process is performed when a game ball is won at the second start port 25.

  Here, the jackpot lottery table according to the present embodiment will be described.

  As shown in FIG. 6, for example, in the jackpot lottery table in the normal mode and the jackpot lottery table in the probability change mode, the lottery values for randomly winning the jackpot game in the lottery values randomly acquired between 1 and 40000 Is set to “100/40000” in the normal mode, whereas “1000/40000” is set in the probability variation mode.

  That is, the sum of the lottery values of 15R probability variable jackpot game, sudden jackpot game, sudden jackpot game, and 15R normal jackpot game, that is, the probability of winning the jackpot game is 1/400 in the normal mode, while the probability variation mode Then, it is set to 10/400 (1/40). In other words, the probability of shifting to the jackpot game differs depending on the game mode (the normal mode and the probability variation mode). When the normal game is in the probability variation mode, the probability of transition to the jackpot game is 10 times higher than the normal mode. It will be. That is, the probability variation mode can be said to be a very advantageous state for the player.

  In the present embodiment, with respect to the jackpot lottery table, in the present embodiment, a first lottery process when a game ball wins at the first start port 24 and a second lottery process when a game ball wins at the second start port 25. In the jackpot lottery table selected for each, the types of jackpot games to be won are different.

  As shown in the drawing, in the first lottery process, the lottery values for the 15R probability variable jackpot game, the sudden jackpot game, and the sudden jackpot game are set, but the lottery value for the 15R normal jackpot game is not set. On the other hand, in the second lottery process, the lottery values for the 15R probability variable jackpot game, the surprise jackpot game, and the 15R normal jackpot game are set, but the lottery value for the sudden jackpot game is not set.

  That is, when the first lottery process when the game ball wins the first start port 24 and the second lottery process when the game ball wins the second start port 25 are compared, the first lottery process In the second lottery process, there is a possibility of winning the 15R normal jackpot game, but there is a possibility that the 15R normal jackpot game will be won. Will not win.

  That is, according to the first start port 24 or the second start port 25 that triggers the jackpot lottery means, the first start is made by changing the winning jackpot game from among the four types of jackpot games in the present embodiment. By characterizing the mouth 24 or the second start port 25 and differentiating, it is possible to enjoy a special jackpot game according to the first start port 24 or the second start port 25.

  Furthermore, in the jackpot lottery table in the present embodiment, not only a special jackpot game corresponding to the first start port 24 or the second start port 25 is set, but also according to the first start port 24 and the second start port 25. In addition, numerical values are set such that there is no difference in the degree of advantage for the player with respect to the number of round games executed in the jackpot game and the rate of entry into the probability variation.

  That is, as shown in FIG. 6, in the first lottery process, the distribution rate of the jackpot game with 15 round games executed is 70% of the 15R probability variable jackpot game, In the lottery process, the sum of 55% of the 15R probability variation jackpot game and 15% of the 15R normal jackpot game is 70%, which is the same as the first lottery process. That is, in the present embodiment, in both the first lottery process and the second lottery process, a ratio of 70% can be expected as the distribution rate to the big hit game with 15 round games executed.

  Furthermore, as shown in FIG. 6, in the first lottery process, the allocation ratio to the jackpot game with probability fluctuation is 85% when 70% of the 15R probability variation jackpot game and 15% of the surprise jackpot game are totaled. On the other hand, in the second lottery process, the sum of 55% of the 15R probability variation big hit game and 30% of the surprise big hit game is 85% as in the first lottery process. In other words, in the present embodiment, in both the first lottery process and the second lottery process, it is possible to expect a ratio of 85% as the allocation rate to the jackpot game with probability variation.

  In the jackpot lottery table used in the present embodiment, as described above, in the probability variation mode, the lottery value is set so that the winning probability for the jackpot game is 10 times that in the normal mode. The lottery values that are the same in both the normal mode and the probability variation mode are set as the allocation rates to the four types of jackpot games in the present embodiment.

  As described above, in the present embodiment, the first lottery process is performed when a game ball is won at the first start port 24, and the second lottery process is performed when a game ball is won at the second start port 25, respectively. It is executed using a lottery table, and a distinctive jackpot game is generated by a starting opening where game balls win, and differentiation is performed, and four types of jackpot games by the first lottery process and the second lottery process are performed. By setting the lottery values so that the number of round games executed and the rate of entry into the probability variation are the same, the degree of advantage for the player at the first start port 24 and the second start port 25 It is possible to provide a pachinko gaming machine that is fair to the player without any difference.

  In the jackpot lottery table shown in FIG. 6 described above, the allocation ratio to the jackpot game with 15 round games executed is 70% in both the first lottery process and the second lottery process, and the probability variation is accompanied. The lottery values of four types of jackpot games (15R probability change jackpot game, sudden hit jackpot game, sudden hit jackpot game, 15R normal jackpot game) are set so that the allocation rate to the jackpot game is 85%. The distribution of the lottery values (that is, the distribution ratio of a plurality of jackpot games) is an important factor as a condition for determining the characteristics of pachinko gaming machines introduced in the market.

  However, pachinko machines that are currently introduced in the market have certain restrictions (so-called play restriction) on the number of rounds executed in jackpot games and the allocation rate to jackpot games with probability fluctuations. And prevents excessive stimulation of the player's gambling. And, for example, it is possible to use a pachinko gaming machine with a higher probability (for example, 95%) than that of this embodiment for the distribution ratio to the jackpot game with probability fluctuation, but this exceeds a certain regulation. This is not possible with an actual pachinko machine. That is, the distribution of the lottery values set in the first lottery process and the second lottery process in the present embodiment (that is, the distribution ratio of a plurality of jackpot games) satisfies the above-mentioned certain regulations, and It can be said that this is an optimal setting for the distribution ratio of multiple jackpot games that are sufficiently satisfactory.

  Returning to the description of the special symbol memory check process shown in FIG. When the jackpot lottery process in step S64 using the jackpot lottery table described above is completed, the main CPU 66 shifts the process to step S65.

  In step S65, the main CPU 66 determines whether or not it is a big hit. In this process, the main CPU 66 moves the process to step S66 if the lottery result in the jackpot lottery process in step S64 described above is a big win, and moves the process to step S67 if not the big win.

  In step S66, a special symbol determination process that is a jackpot symbol is executed. In this process, the main CPU 66 determines a special symbol to be displayed corresponding to the jackpot type determined in step S64. For example, the special symbol for “15R probable jackpot game” is “7”, the special symbol for “surprise jackpot game” is “3”, the special symbol for “sudden jackpot game” is “1”, and the special symbol for “15R normal jackpot game” The special symbol is determined corresponding to each jackpot game, such that “5” is determined as the special symbol. Then, the determined special symbol is stored in a predetermined area of the main RAM 70. Thereby, the first special symbol display 33 or the second special symbol display corresponding to each start port (the first start port 24 or the second start port 25) installed in the electric decoration unit 53 (see FIG. 4). In the device 34, a special symbol corresponding to the jackpot game is derived and displayed.

  Further, in the present embodiment, in the process of step S66, the main CPU 66 determines the four types of jackpot games determined in step S64 (15R probability variable jackpot game, sudden jackpot game, sudden jackpot game, 15R normal jackpot game). And the number of occurrences of the jackpot are stored and updated as a “hit game history” in a predetermined area of the main RAM 70 for each of the first start port 24 and the second start port 25 serving as the lottery opportunity. Then, when this process ends, the process moves to step S68.

  In step S67, a missing symbol determination process is executed. In this process, the main CPU 66 determines a special symbol (for example, a number other than “7”, “3”, “1”, “5”) corresponding to the off symbol and stores it in a predetermined area of the main RAM 70. Thereby, the first special symbol display 33 or the second special symbol display corresponding to each start port (the first start port 24 or the second start port 25) installed in the electric decoration unit 53 (see FIG. 4). In the device 34, a special symbol corresponding to the deviation is derived and displayed. If this process ends, the process moves to a step S68.

  In step S68, a gaming state determination process is performed. In this gaming state determination process, the main CPU 66 determines whether or not the current normal game is in the time-saving mode, and if it is in the time-saving mode, the process proceeds to step S70. On the other hand, if it is determined that the current normal game is not in the time reduction mode, the special symbol variation time (for example, 10 seconds) in the normal mode is set in the special symbol variation timer and stored in a predetermined area of the main RAM 70 in step S69. To do. Then, the process proceeds to step S71.

  In step S70, the main CPU 66 sets a special symbol variation time in the probability variation mode or the short time mode (a time shorter than the special symbol variation time in the normal mode, for example, 5 seconds) in the special symbol variation timer. Store in the area. Further, in the process of step S70, the main CPU 66 subtracts "-1" from the number of special symbol fluctuations (for example, 100) stored in a predetermined area of the main RAM 70 as the duration of the time reduction mode and updates the memory. To do. When the number of fluctuations of the special symbol becomes “0”, that is, when the duration of the time reduction mode ends, the time reduction mode is reset (the flag of the time reduction mode stored in a predetermined area of the main RAM 70 is cleared). Then, the process proceeds to step S71.

  In step S71, the main CPU 66 responds to the first special symbol display 33 or the second special symbol display 34 (see FIG. 4) corresponding to the first starting port 24 or the second starting port 25 where the game ball has won. The request for starting the variable display is stored in a predetermined area of the main RAM 70, and the process proceeds to step S72.

  By this processing, the first special symbol display corresponding to each start port (the first start port 24 or the second start port 25) according to the variation time set in the special symbol variation timer in step S69 and step S70. The special symbol fluctuation display is performed on the device 33 or the second special symbol display 34, and after a predetermined time has elapsed (after the special symbol fluctuation timer has timed out), the “big hit” determined in the above step S66 and step S67 or The special symbol of “out” will be stopped and displayed.

  In step S72, the decoration pattern displayed in the display area 32a of the liquid crystal display device 32 and the effect time determination process are performed. In this processing, the main CPU 66 displays the liquid crystal display based on the data such as “big hit” or “out of place” stored in step S66 or step S67 and the special symbol variation time stored in step S69 or step S70. The decorative design and effect time displayed in the display area 32a of the device 32 are determined, stored in a predetermined area of the main RAM 70, and this subroutine is finished.

  The decorative design and effect time displayed in the display area 32a of the liquid crystal display device 32 stored here are transmitted from the main CPU 66 of the main control circuit 60 to the sub control circuit 200 by the command output process in step S25 of FIG. Is supplied to the sub CPU 206 as a derived symbol designation command. As a result, in the sub-control circuit 200, decorative symbols corresponding to the respective start ports (the first start port 24 or the second start port 25) are derived and displayed in the display area 32a of the liquid crystal display device 32, and the decorative symbols are displayed. The variation time is also determined. That is, in the electrical decoration unit 53 (see FIG. 4), the first special symbol display 33 or the second special symbol display 34 corresponding to each start port (the first start port 24 or the second start port 25) is derived. The variation time of the special symbol to be displayed and the variation time of the decorative symbol derived and displayed on the liquid crystal display device 32 are synchronized.

[Normal symbol control processing]
The subroutine executed in step S13 in FIG. 7 will be described with reference to FIG.

  First, the main CPU 66 loads a normal symbol control flag in step S101. In this process, the main CPU 66 reads the normal symbol control flag. If this process ends, the process moves to a step S102.

  In step S102, the main CPU 66 determines whether or not the normal symbol control flag is a value (00) indicating a normal symbol storage check request. If the normal symbol control flag is not (00), the process proceeds to step S104. . If the normal symbol control flag is (00), the normal symbol storage check process in step S103 is performed. This normal symbol storage check process will be described in detail with reference to FIG. 12, but the main CPU 66 checks the number of reserved normal symbols, and if there is a number of reserved symbols, the main CPU 66 determines whether the normal symbol is hit, starts changing the normal symbol, The normal symbol variation timer is set, etc., and (01) which is the processing request for the next step is set in the normal symbol control flag, and the processing is terminated.

  In step S104, the main CPU 66 determines whether or not the normal symbol control flag is (01). If the normal symbol control flag is not (01), the process proceeds to step S107. If the normal symbol control flag is (01), it is determined in step S105 whether the normal symbol variation timer has timed up (that is, “0”). If the time has not expired, the process ends. . On the other hand, when the normal symbol variation timer expires, the main CPU 66 performs a normal symbol stop process in step S106. In this normal symbol stop process, the main CPU 66 sets a request to stop the fluctuation to the normal symbol display 35 and stores it in a predetermined area of the main RAM 70. As a result, the normal symbol display 35 displays the determination result of “success” or “displacement” of the normal symbol determined by the normal symbol storage check process. When this process is completed, the stored number of normal symbols stored in a predetermined area of the main RAM 70 is updated so as to decrease by “1”. Then, (02) is set in the normal symbol control flag and the process is terminated.

  In step S107, the main CPU 66 determines whether or not the normal symbol control flag is (02). If the normal symbol control flag is not (02), the process proceeds to step S111. If the normal symbol control flag is (02), the process proceeds to step S108 to determine whether or not the normal symbol is a hit. If the main CPU 66 determines that the normal symbol is a winning symbol, the main CPU 66 shifts the process to the normal electric accessory release process in step S109. On the other hand, when determining that the normal symbol is not a hit, the main CPU 66 sets a value (00) for requesting the normal symbol storage check to the normal symbol control flag and ends the processing in step S110.

  In the ordinary electric accessory release process in step S109, the main CPU 66 performs an opening process of the blade member 23, which is an ordinary electric accessory (stores the release of the ordinary electric accessory in a predetermined area of the main RAM 70). Furthermore, according to the gaming state of the gaming table, the opening time of the ordinary electric accessory (wing member 23) (for example, 3 seconds when the game mode is the short-time mode, 0.2 seconds when the game mode is the normal mode or the normal mode) The normal electric accessory release timer is set, the normal symbol control flag is set to (03), and the process is terminated.

  In step S111, the main CPU 66 determines whether or not the normal symbol control flag is (03). If the normal symbol control flag is not (03), the process proceeds to step S114. If the normal symbol control flag is (03), the process proceeds to step S112 to determine whether the normal electric accessory release timer has timed up (that is, “0”). Then, when the normal electric accessory release timer has not expired, the process is terminated. On the other hand, when it is determined that the normal electric accessory release timer has timed out, in the normal electric accessory closing process of step S113, the blade member 23, which is an ordinary electric accessory, is closed (normally in a predetermined area of the main RAM 70). Memorize the closing of the electric accessory). Then, (04) is set in the normal symbol control flag and the process is terminated.

  In step S114, the main CPU 66 clears the normal symbol control flag (that is, sets the value “00” for requesting the normal symbol storage check) and ends the process.

[Normal symbol memory check processing]
The subroutine executed in step S103 in FIG. 11 will be described with reference to FIG.

  First, in step S121, the main CPU 66 determines whether or not the normal symbol holding number is “0”. If it is determined that the normal symbol holding number is “0”, the normal symbol storage check is performed. The process ends. This normal symbol holding number is stored in a predetermined area of the main RAM 70. When it is detected that a game ball has passed through the passing gate 54, the normal symbol holding number increases by "1" with the predetermined number (for example, "4") as an upper limit. When the variable display of the normal symbol in the normal symbol game is completed, “1” is subtracted and the memory is updated. On the other hand, if the main CPU 66 determines that the number of retained normal symbols is not “0”, in step S122, the main CPU 66 sets the value “01” of the normal symbol variation timer monitoring request to the normal symbol control flag, and then proceeds to step S123. Move processing.

  In step S123, a normal symbol hit determination process is executed. In this processing, the main CPU 66 determines the normal symbol per-determining random number extracted when the normal symbol starting region passes (by passing the game ball through the passing gate 54) and the normal symbol per-unit determination stored in the main ROM 68. Refers to the value. Then, as a result of the reference, when the random value for determination per ordinary symbol matches the determination value per ordinary symbol as a result of the reference, the main CPU 66 stores data indicating the winning symbol (for example, “◯” symbol) in a predetermined area of the main RAM 70. To remember. On the other hand, as a result of the reference, when the random value for determination per normal symbol does not match the determination value per normal symbol as a result of the reference, the main CPU 66 stores data indicating an off symbol (for example, “×” symbol) in a predetermined area of the main RAM 70. To remember. The winning symbol and the off symbol stored in this way are supplied to the normal symbol display 35 as a derived normal symbol designation command in the illumination unit 53 (see FIG. 4). As a result, the normal symbol display 35 starts normal symbol variation display (for example, “◯” and “x” symbols are alternately blinked). Thereafter, the process proceeds to step S124.

  In step S124, the main CPU 66 determines whether or not the normal game is in the time reduction mode. If the normal game is in the time reduction mode, in step S126, the main CPU 66 stops the normal symbol fluctuation shorter than the normal mode. The time (for example, 5 seconds) is set in the normal symbol variation timer, and the process ends. On the other hand, when the game mode is not the time reduction mode (that is, the probability variation mode or the normal mode), in step S125, the main CPU 66 sets a normal symbol variation stop time (for example, 30 seconds) longer than the time reduction mode in the normal symbol variation timer. To finish the process.

[Sub control circuit main processing]
On the other hand, the sub-control circuit 200 executes the sub-control circuit main process. The sub control circuit main process will be described with reference to FIG. The sub control circuit main process is a process that is started when the power is turned on.

  First, in step S201, the sub CPU 206 executes initial setting processing such as RAM access permission and work area initialization. That is, the sub CPU 206 performs a predetermined initial setting for normally playing the game based on the power being turned on. In the present embodiment, the sub CPU 206 that executes step S201 corresponds to an example of an initial setting unit. If this process ends, the process moves to a step S202.

  In step S202, the sub CPU 206 executes random number update processing. In this process, the sub CPU 206 updates various random number values positioned in a predetermined area of the work RAM 210. If this process ends, the process moves to a step S203.

  In step S203, the sub CPU 206 executes command analysis processing. In this process, the sub CPU 206 analyzes various commands (for example, a derived symbol designation command) sent from the main CPU 66 of the main control circuit 60, and executes a process according to the analyzed command. If this process ends, the process moves to a step S204.

  In step S204, the sub CPU 206 executes display control processing. In this process, when the sub CPU 206 receives a derived symbol designation command from the main CPU 66 of the main control circuit 60 in the command analysis process, the sub CPU 206 performs image display control such as a decorative symbol according to the derived symbol designation command. This is performed in the display area 32 a of the liquid crystal display device 32.

  Then, the sub CPU 206 executes sound control processing (step S205) for controlling sound generated from the speakers 46R and 46L and lamp control processing for controlling light emission of the various decorative lamps 133a and 133b (step S206). If this process ends, the process moves to a step S202.

  As described above, in the sub control circuit main process, after the initial setting process in step S201 is completed, the processes from step S202 to step S206 are repeatedly executed.

[First start port 24 and second start port 25]
Here, the configuration of the first start port 24 and the second start port 25 in the present embodiment will be described, the first lottery process when a game ball wins the first start port 24, and the second start port 25. In the second lottery process when a game ball wins, the game is further performed by opening and closing the blade member 23 attached to the first starting port 24 controlled in the above-described normal symbol control process (see FIG. 11). A change in the flow of the sphere will be described. FIG. 14 is a perspective view for explaining the positional relationship between the second game member 57 and the first start port 24 and the second start port 25. FIG. 15 is a game ball by the opening and closing operation of the blade member 23 attached to the first start port 24. It is explanatory drawing which shows the change of the flow down.

  As shown in FIG. 14, a second game member 57 is provided at a substantially central portion of the game area 15, and a second start port 25 is provided at an appropriate interval below the second game member 57. A first start port 24 to which a blade member 23 is attached is provided. That is, the game ball fired on the game board 14 rolls due to a collision with the plurality of game nails 13 and the first game member 55 provided in the upper part of the game area 15, and a part thereof is the second game member 57. Thus, the other game balls flow down to the upper side of the second start opening 25 or the lower part of the game area 15 while repeating rolling. As described above, the second gaming member 57 is formed in a stage shape that is gently curved downward, and a guide groove 57a is formed at the center position that is the bottom of the second gaming member 57, so that it is received by the second gaming member 57. Among the game balls, the game ball falling from the guide groove 57a has a higher winning probability to the second start port 25 than the game ball falling from the other part.

  In the pachinko gaming machine 10, the winning of the game ball to the first start port 24 and the second start port 25 is the trigger of the "big hit game", which is the greatest profit for the player, Normally, a game is played by adjusting the firing strength of the launch handle 26 so that game balls are concentrated around the first start port 24 and the second start port 25.

  As shown in FIG. 15A, the game ball launched into the game area 15 is temporarily received by the second game member 57 configured in a stage shape, and passes through the guide groove 57a of the second game member 57. It is guided to flow down to the upper part of the second start port 25. Then, the game balls that have not won the second starting port 25 flow down to the lower part to the second starting port 25. A game ball that has not collided with the second game member 57 and a game ball that has not flowed down from the guide groove 57a of the second game member 57 may also flow down toward the second start port 25.

  In the present embodiment, there is no gap between the first start port 24 and the second start port 25. Therefore, when the game ball flowing down from the guide groove 57a of the second game member 57 does not win the second start port 25, the first start port is provided unless the blade member 23 attached to the first start port 24 is opened. The winning 24 is not expected.

  Then, as shown in FIG. 15B, when the blade member 23 attached to the first starting port 24 is opened, the second starting member passes through the guide groove 57a of the second gaming member 57 described above. The game balls guided to flow down to the upper part of the mouth 25 may win the second starting port 25, but most of them are received by opening the blade member 23 attached to the first starting port 24, The first start opening 24 will be won.

  That is, in this embodiment, when the game mode of the normal game is “time reduction mode + normal mode” or “probability change mode + time reduction mode”, the opening frequency of the blade member 23 attached to the first start port 24 increases. Since the opening time is also set longer, the winning rate of game balls to the first start port 24 and the second start port 25 changes greatly compared to the case where the game mode is the “normal mode” (that is, In the time reduction mode, the winning rate for the first start port 24 is greatly improved).

  As described above, there are four types of jackpot games (15R probability variation jackpot game, sudden jackpot game, crash game, when the game ball wins the first start port 24 and when the game ball wins the second start port 25. Although the winning probability for the time jackpot game and the 15R normal jackpot game is the same, if a game ball wins the first starting port 24, there is a possibility that the hit jackpot game most disadvantageous to the player may occur. . On the other hand, when a game ball is won at the second start opening 25, a big hit game that is unfavorable to the player does not occur (see the big hit lottery table in FIG. 6). In other words, with the above-described configuration, the frequency of occurrence of a sudden jackpot game is suppressed as a jackpot game that the player can acquire for the first time.

  As a result, since the first jackpot game acquired by the player is a sudden jackpot game with the least advantageous degree to the player, it is possible to prevent the player's willingness to be attenuated and When a game ball wins the first starting port 24 for the first time in the time-saving mode after the execution of the jackpot game where the player has a higher degree of advantage compared to the time jackpot game, a sudden jackpot game is generated. Therefore, the pachinko gaming machine 10 in which the history of occurrence of the four types of jackpot games (15R probability change jackpot game, sudden hit jackpot game, sudden hit jackpot game, 15R normal jackpot game) in this embodiment is balanced and can do.

  As described above, in the pachinko gaming machine 10 according to the present embodiment, there are two types of specific winning holes for the lottery game lottery, the first start port 24 and the second start port 25, and the jackpot lottery. When the first lottery process triggered by the winning of the game ball to the first starting port 24 by the means and the second lottery process triggered by the winning of the game ball to the second starting port 25 are compared, Although the degree of advantage (for example, the expected value of the number of executions of the round game of the jackpot game or the rate of entry into the probability variation) is not different, there are two types of start ports (the first start port 24 and the second start port 25). By setting a corresponding jackpot game, that is, a sudden jackpot game at the first start port 24, and a 15R normal jackpot game at the second start port 25, two of the first start port 24 and the second start port 25 are set. It can be differentiated characterize the starting opening classes.
