Description

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

In a ball game machine called the first type pachinko machine, a random number is acquired when a hitting ball is won at a start winning opening on the game board, and the acquired random number is compared with a predetermined determination value. Then, it is determined whether or not the symbol is a big hit. In the case of a big win, the game shifts to a special game in which a prize opening called a big prize opening is opened. In recent years, when the symbol for transitioning to a special game is in a specific mode such as “777”, for example, after the end of the special game, the symbol jackpot is determined using a judgment value having a higher percentage of jackpots than the normal judgment value A ball game machine equipped with a so-called probability-variable game for judging the above is widely popular. In addition, a ball game machine equipped with a so-called short-time game in which the special symbol variation time is shortened compared with the normal game after the special game is ended.

  Comparing special games with short-time games or probability-changing games with special jackpots and special games with normal jackpots, there is a difference in the variation time of special symbols after the end of special games and the lottery probability of jackpot determination after the end of special games However, the special game to be executed is configured as the same thing. In conventional ball game machines, special games are executed only to return profits to the players, and the maximum opening time of the big prize opening is a jackpot with short-time games or probability-variable games It is set to a predetermined time regardless of whether or not. Therefore, from the viewpoint of the player, the special game is merely a game for obtaining profits, and the game is monotonous. In addition, in the conventional ball game machine, there is only one big prize opening, but it is considered that a new game can be created by providing a plurality of big prize openings.

  The present invention has been made in view of such problems, and an object of the present invention is to provide a ball game machine rich in gaming interest by effectively using a plurality of large winning openings.

  In order to solve the above-described problems, a bullet ball game machine according to an aspect of the present invention includes a game board in which a game area is formed, a start port provided in the game area and into which a game ball can enter, and a game area. State change of the first variable pitching device and the second variable pitching device, and the first variable pitching device and the second variable pitching device, which are provided and are capable of changing the accepting state of the game ball to a state advantageous to the player Special control for changing at least one of the first variable pitching device and the second variable pitching device into a state advantageous to the player based on the state control means for controlling the game and the entrance of the game ball to the start port A lottery means for determining whether or not to generate a game; a special game control means for executing a special game when it is determined by the lottery means that a special game is to be generated; A specific game control hand that executes a specific game different from Provided with a door. When it is determined that the special game is generated by the lottery means during execution of the specific game, the state control means changes the second variable pitching device to an advantageous state, and the special game is executed by the lottery means during execution of the normal game. When it is determined that the first variable pitching device is generated, the first variable pitching device is changed to an advantageous state. For example, in the case where the first variable pitching device and the second variable pitching device are configured as open / closed winning holes, an open state in which a game ball can be received is advantageous to the player, and a game ball cannot be received. The closed state corresponds to a disadvantageous state for the player. The specific game may be a game in which the variation time of the special symbol is shortened compared to the normal game.

  According to this aspect, it is possible to determine the variable pitching device whose state is changed according to the gaming state when it is determined that the special game is generated by the lottery means. As a result, it is possible to change the special game, and it is possible to effectively use the special game that has been merely a game for obtaining profits, and to improve the game performance of the ball game machine.

  The state control means may set the time for changing the second variable pitching device to an advantageous state longer than the time for changing the first variable pitching device to an advantageous state. As a result, the second variable pitching device can be kept in an advantageous state as compared with the first variable pitching device for a long time, and the player can be given more profits. In this way, by changing the time for maintaining an advantageous state, it is possible to change the special game and enhance the game entertainment.

  The state control means may set the same number of times to change the first variable pitching device and the second variable pitching device to an advantageous state during the special game. Regardless of the type of the variable pitching device that is changed to an advantageous state, the execution control of the special game can be facilitated by making the number of changes to the advantageous state the same.

  The specific game control means ends the special game depending on whether it is determined to generate a special game during execution of the specific game or whether to generate a special game during execution of the normal game. You may set the frequency | count or execution time of the specific game performed later. In addition, when it is determined that the special game is generated during the execution of the specific game, the specific game control means shifts the execution frequency or execution time of the specific game after the special game from the normal game to the special game. It may be set longer than the number of executions of the specific game to be performed later or longer than the execution time.

  When it is determined that a special game is to be generated, the lottery means may determine whether or not to generate the specific game after the special game is ended. By determining the occurrence of the specific game by lottery, the gameability of the ball game machine can be enhanced.

  ADVANTAGE OF THE INVENTION According to this invention, the ball ball game machine which was rich in game entertainment can be provided by utilizing a some large winning opening effectively.

  The game board 50 has an out port 58, a special symbol display device 61, an effect symbol display device 60, a start winning port (hereinafter referred to as “start port”) on a game area 52 defined by the outer rail 54 and the inner rail 56. 62, a center ornament 64, a first grand prize winning port 66, a second major prize winning port 96, and a general prize winning port 72. Furthermore, in the game area 52, a plurality of mechanisms such as a game nail and a windmill (not shown) are installed. The start port 62 includes a winning detection device 74 for detecting the entrance of a game ball and a normal electric accessory solenoid 76 for expanding the start port. The first grand prize winning port 66 includes a prize detecting device 78 for detecting the entry of a game ball, and a first big prize winning port solenoid 80 for expanding the first grand prize winning port 66. The second grand prize opening 96 includes a prize detection device 94 for detecting the entry of a game ball and a second big prize opening solenoid 92 for expanding the second grand prize opening 96.

  The first grand prize winning port 66 and the second grand prize winning port 96 are variable ball entering devices that can change the accepting state of the game ball to a state advantageous to the player. The first grand prize winning port 66 and the second grand prize winning port 96 are configured as horizontal rectangular prize winning holes that are opened as “big hits” when the special symbol 202 stops in a predetermined manner. The first big prize opening 66 is provided at a position above the out mouth 58 and the second big prize opening 96 is provided at the upper right position of the first big prize opening 66. The first grand prize winning port 66 and the second grand prize winning port 96 may be arranged with a relatively high degree of positional freedom. During the big hit game (special game), one of the first big prize winning port 66 and the second big prize winning port 96 is in an open state, and the game ball can be received. In the present embodiment, only one of the first grand prize winning port 66 or the second grand prize winning port 96 is opened, and both are not opened simultaneously.

  The insides of the first grand prize winning port 66 and the second grand prize winning port 96 are divided into a specific area (so-called V zone) and a general area. The winning detection device 78 of the first big winning opening 66 is configured to include a sensor that detects passage of a game ball through a specific area and a sensor that detects passage of a general area. Similarly, the winning detection device 94 of the second grand prize opening 96 includes a sensor that detects passage of a game ball through a specific area and a sensor that detects passage of a general area. Note that the specific area may not exist, and in this case, it is only necessary to provide one sensor for detecting the winning at the first big winning opening 66 and the second big winning opening 96. The first grand prize winning port 66 and the second grand prize winning port 96 may have the same structure.

  The special symbol display device 61 and the production symbol display device 60 provided substantially in the center of the game board 50 display the special symbol 202 and the decorative symbol 200 linked to the special symbol 202 on the respective screens while fluctuating (hereinafter, referred to as the special symbol 202). Such a display is called “symbol change” or “change display”). Here, the special symbol 202 is a symbol corresponding to the result of the lottery performed when the game ball is dropped into the start port 62, and has a role of indicating whether or not to generate a big hit. The special symbol display device 61 is display means composed of, for example, LEDs.

  The effect symbol display device 60 displays the decorative symbol 200 while fluctuating in a manner interlocking with the fluctuating display of the special symbol 202. The decorative symbol 200 is a symbol for visually producing the result display of the special symbol lottery indicated by the special symbol 202. In the present embodiment, the decorative symbol 200 may express an effect for explaining predetermined game contents to the player. The effect symbol display device 60 displays, as the decorative symbol 200, for example, a plurality of rows of moving images of symbol variation that simulate a slot machine game in the central area of the screen. The effect symbol display device 60 is configured by a liquid crystal display in this embodiment, but may be configured by other display means such as a mechanical drum or LED. Since the special symbol 202 does not need to have a role of production, the special symbol 202 is displayed in an inconspicuous size on the special symbol display device 61 at the lower left of the production symbol display device 60 in this embodiment.

  A center ornament 64 is provided around the effect symbol display device 60. The center decoration 64 has functions such as protection of the game ball flow path, the special symbol display device 61 and the effect symbol display device 60, and decoration. A holding lamp 20 is provided at a predetermined position of the center decoration 64. The holding lamp 20 is composed of four lamps, and displays the number of holding balls according to the number of lights. The number of reserved balls is the number of lottery results won to the start port 62 during symbol variation, and indicates the number of winning balls for which symbol variation has not yet been executed. In addition, a game effect lamp 90 is provided in the game area 52 and plays a role of production by blinking or the like.

  When the game ball passes through the operating port 68, a symbol called a normal symbol 204 is displayed in a variable manner for a predetermined time. The normal symbol 204 is variably displayed at the lower right corner of the effect symbol display device 60. When the fluctuation display of the normal symbol 204 is stopped after the lapse of a predetermined time, the start port 62 is normally expanded for a predetermined time with a probability of about 50% to 80%.

  When the player turns the launch handle 17 by hand, the game balls stored in the upper ball tray 15 are guided one by one to the inner rail 56 and the outer rail 54 with a strength corresponding to the turning angle, thereby playing the game area. To 52. When the player fixes the rotation position of the firing handle 17 by hand, the game ball is repeatedly fired at regular time intervals. The game ball launched to the upper part of the game area 52 falls in a direction according to the way of hitting while hitting a plurality of game nails and windmills. When a game ball is dropped into each of the general winning opening 72, the start opening 62, the first large winning opening 66, and the second large winning opening 96, the winning ball corresponding to the type of the winning opening is the upper ball tray 15 or It is paid out to the lower ball tray 16. A game ball dropped into each winning hole such as the general winning hole 72 is processed as a safe ball, and a game ball dropped into the out hole 58 is processed as an out ball. Each winning opening includes a gate type through which game balls pass.

  When the game ball falls into the start port 62, the special symbol 202 and the decorative symbol 200 are variably displayed on the special symbol display device 61 and the effect symbol display device 60. In principle, the variation display of the special symbol 202 and the decorative symbol 200 is stopped based on the variation pattern determined prior to the display. When the special symbol 202 and the decorative symbol 200 at the time of the stop are symbols showing a big hit, the opening / closing operation of the first big winning port 66 or the second big winning port 96 is started, and a gaming state advantageous to the player over the normal game It shifts to a special game that is. The special game is a game in which the first big prize opening 66 or the second big prize opening 96 is changed at least once into a state advantageous to the player. Specifically, in the special game, the first grand prize winning port 66 or the second grand prize winning port 96 is opened at least once to enter a state where a game ball is accepted.

  The symbols indicating the jackpot are, for example, symbols from 0 to 9 in the special symbol 202, and three matching symbols in the decorative symbol 200 imitating a slot machine game. For example, if the special symbol is a predetermined symbol, a specific game that is more advantageous than the normal game is generated after the special game is ended. This specific game is, for example, a so-called “time-short game” in which the variation time of a special symbol is shortened compared to a normal game. When the special symbol stops at a symbol that generates a short-time game (hereinafter referred to as a “short-time symbol”), the short-time game is started after the special game ends. At this time, in the short game, not only the variation time of the special symbol is shortened compared to the normal game, but also the opening probability of the start port 62 is set higher than that of the normal game, and the open time is set longer than that of the normal game. An advantageous gaming state can be provided.

  In the pachinko gaming machine 10 of this embodiment, at least two types of special games are set. Specifically, a first special game with a short maximum duration and a second special game with a long maximum duration are set. In addition, the length of the maximum duration is relative between the first special game and the second special game. For example, when there are a plurality of special games having a relatively long maximum duration with respect to a first special game having a short maximum duration, they may be collectively referred to as a second special game. In the pachinko gaming machine 10 according to the present embodiment, there may be a third special game other than the first special game and the second special game.

  In the first special game, the first grand prize opening 66 is opened for about 0.5 seconds and then closed. The number of rounds is set to 2 rounds, and therefore the opening and closing of the first big prize winning opening 66 is repeated twice. The interval between rounds is also set to a short time. Therefore, in the first special game, there is a low possibility that the game ball will fall into the first grand prize opening 66, and the player cannot expect to play in the first special game.

  In the second special game, the second grand prize opening 96 is temporarily closed after being opened for about 29 seconds or after nine or more game balls have dropped. If at least one game ball falls into the specific area while the second big prize opening 96 is opened, the second big prize opening 96 is opened again. In this way, the second grand prize opening 96 is opened and closed a predetermined number of times, for example, three times, on condition that at least one game ball falls into the specific area while the second big prize opening 96 is opened once. Repeated. The above assumes the case where the second grand prize opening 96 is opened once per round of the second special game, but there may be a plurality of releases per round. As described above, when the second grand prize opening 96 does not have a specific area, the continuation determination to the next round is not performed, and the opening and closing of the second big prize opening 96 is always repeated three times. Will be.

  As described above, the first special prize opening 66 is opened and closed in the first special game, while the second big prize opening 96 is opened and closed in the second special game. In different special games, the role of each special winning opening can be clarified by opening and closing the separate special winning openings. In addition, since the player can identify the type of special game by the special winning opening that is opened, the current game situation can be accurately grasped.

  Comparing the first special game and the second special game, in the first special game, the opening time of the first grand prize opening 66 is set to be relatively short, and the first big prize opening 66 in the previous round is set. The time from the completion of the opening to the opening of the first big prize opening 66 in the following round is also set short. Thereby, when the maximum total time from the start to the end of the special game is compared, the first special game ends in a much shorter time than the second special game. As described above, when the number of rounds of the first special game is set to 2 rounds and the number of rounds of the second special game is set to 3 rounds, the difference becomes more remarkable. Even if the number of times of opening and closing the first grand prize opening 66 and the second grand prize opening 96 is the same, the opening time of the first big prize opening 66 in the first special game and the first grand prize in the previous round The first special game ends in a shorter time than the second special game because the time from the closing of the mouth 66 to the opening of the first big winning opening 66 in the subsequent round is shorter. In the pachinko gaming machine 10 according to the present embodiment, it is possible to improve the gaming interest by effectively using the first special game and the second special game.

  In the pachinko gaming machine 10 of the present embodiment, the jackpot probability during the game is set to 1/40, for example. Currently, in many pachinko gaming machines installed in a hall, the jackpot probability is set to about 1/300, and a game that cannot easily win a jackpot is common. On the other hand, the pachinko gaming machine 10 of the present embodiment sets the jackpot probability relatively high, and changes the profit given to the player according to the gaming state of the pachinko gaming machine 10 when the jackpot.

  The first special game occurs when a big hit is made during a normal game. At this time, if a big hit is made with a time-short symbol, a time-short game is performed after the first special game is ended, for example, the number of time-savings is four. At this time, if a big hit is made with a short time symbol during the short game, a second special game is generated. If there is no big hit during the four short-time games, the game returns from the short-time game to the normal game. After that, even if a big hit is made with the short-time design, the second special game does not occur and the first special game occurs again. . Also, during a short-time game, even if a big hit is made with a symbol that is not a short-time symbol, the second special game is not generated and the first special game is generated. When the second special game ends, for example, a time-saving game is performed in which the time-saving number is set to 100 times.

  In this way, in the pachinko gaming machine 10, when a big hit is made, the special game to be generated is determined according to the gaming state whether or not the short-time game is being executed and the mode of the special symbol at that time. When a big hit is made during a short-time game, the second special game may be always generated. In this case, the special symbol mode is not taken into consideration.

  FIG. 2 shows a basic structure on the back side of the pachinko gaming machine. The power switch 40 is a switch for turning on / off the power of the pachinko gaming machine 10. The main board 41 controls the overall operation of the pachinko gaming machine 10 and processes all game operations such as a lottery when a winning is made to the start port 62. The sub board 49 includes a liquid crystal unit 42 and controls display contents on the effect symbol display device 60 and sound output from the speaker 18, and in particular, effects processing according to the lottery result by the main board 41. In the present embodiment, the main board 41 and the sub board 49 constitute an inspection device for checking the contents of the mounted ROM. The set base 39 includes a prize ball tank 44, a flow path for prize balls, a payout unit 43 for delivering prize balls. The payout unit 43 pays out the game balls supplied from the winning ball tank 44 to the upper ball tray 15 in accordance with winning in each winning opening. The payout control board 45 controls the payout operation by the payout unit 43. The launching device 46 launches the stored balls in the upper ball tray 15 to the game area 52 one by one. The launch control board 47 controls the launch operation of the launch device 46. The power supply unit 48 supplies power to each part of the pachinko gaming machine 10.

  FIG. 3 is a basic functional block diagram focusing on a configuration for controlling a game in the pachinko gaming machine 10. The start opening 62, the first grand prize opening 66, the second big prize opening 96, the special symbol display device 61, the production symbol display device 60, the speaker 18, the various game effect lamps 90, and the game control device 100 are electrically connected. It is connected to the. The game control device 100 can be realized by hardware such as a ROM for storing data and programs, a CPU and a RAM used for arithmetic processing and control processing, and in terms of software, an image processing function, a control function, and random number generation. This function is realized by a program such as a function, but in this drawing, functional blocks realized by their cooperation are depicted. Therefore, these functional blocks can be realized in various forms by a combination of hardware and software.

  The game control apparatus 100 is a special game that changes the ball entering determination means 110 for determining whether or not to enter the ball entrance, the first grand prize winning port 66 or the second big prize winning port 96 to a state advantageous to the player at least once. Lottery means 120 for determining whether or not to generate, special game determining means 125 for determining a special game, symbol determining means 130 for determining a symbol, pattern storage means 140 for storing a variation pattern of a symbol, and controlling a special game State of the special game control means 150, the specific game control means 160 for controlling the specific game after the end of the special game, the display control means 170 for performing display processing of the display device, and the state of the first grand prize winning port 66 or the second grand prize winning port 96 State control means 180 for controlling the change is provided.

  The winning detection device 74 is a sensor provided at the start port 62, detects the drop of the game ball into the start port 62, and generates start win information indicating the drop. When receiving the start winning information, the winning determination means 110 determines that the game ball has won the start opening 62. At the timing when the winning determination means 110 receives the start winning information, the random number acquiring means 122 in the lottery means 120 acquires a random number for the starting winning. The random number acquisition means 122 may acquire and acquire a random number mathematically, or may acquire a count value generated by a counter (not shown) as a random number. The hit determination means 124 determines whether or not to generate a special game by comparing the random number value with a predetermined determination value.

  When it is determined that a special game is to be generated, the lottery means 120 determines whether or not to generate a short-time game after the end of the special game. That is, it is determined whether or not the special game is with a short-time game. Note that “with a short-time game” means that the game after the end of the special game is accompanied by a game whose variation time is shorter than that of the normal game by a predetermined number of variations.

  When it is determined by the lottery means 120 that a special game is to be generated, the special game determination unit 125 determines a special game to be executed depending on whether or not a specific game, here a short-time game is being executed. decide. In the present embodiment, the special game determining means 125 takes into account the stop symbol pattern when determining the special game.

  The special game determination means 125 monitors the gaming state of the pachinko gaming machine 10, and when it is determined that a special game is to be generated, that is, when a big hit is made, the short-time game is being executed or the normal game is being executed. It is determined whether it was. When the big hit is made during the normal game, the special game determination means 125 selects the first special game as the special game. On the other hand, when a big hit is made during a short-time game, it is further determined whether or not the special symbol stop mode is a short-time symbol. That is, when it is determined in the lottery means 120 that the special game generated during the short-time game is accompanied by the short-time game, the special game determination means 125 selects the second special game as the special game. Note that, in the case of a short game, when the big hit is made with a symbol other than the short time symbol, the special game determining means 125 selects the first special game as the special game.

  The pachinko gaming machine 10 of the present embodiment enhances the game interest by determining the first special game and the second special game according to the gaming state whether or not the short-time game is being executed. In the present embodiment, in the first special game, the opening time of the first grand prize opening 66 is short, and it is difficult for the player to expect a game, but in the second special game, the second big prize opening 96 is opened. Since time is long, the player can expect to play. The player first generates a first special game with a short-time game, and generates a second special game by making a jackpot with a short-time symbol during the short-time game after the end of the first special game. When the second special game is entered, after the second special game is completed, a time-saving game of 100 time-savings is generated. Since the second special game ends in three rounds, there are not many games per game, but the possibility of acquiring the second special game continuously by giving 100 short-time games to the player There is. By setting the jackpot lottery probability to 1/40 and increasing the frequency of jackpots, the player can enjoy the game without getting bored. In this way, in the special game, the pachinko gaming machine 10 with high gaming interest can be realized by using the first grand prize winning port 66 and the second big prize winning port 96 according to the gaming state.

  The special game control unit 150 controls execution of the first special game or the second special game determined by the special game determination unit 125. During the execution of the first special game, the special game control means 150 instructs the state control means 180 to execute the opening of the first big prize opening 66 for 0.5 seconds at a predetermined timing. The first grand prize opening 66 is opened at most twice, and the special game control means 150 controls the execution of the first special game based on the number of winnings to the first big prize opening 66 and success / failure conditions. To do. Actually, it is considered that the number of game balls that win the first grand prize opening 66 during the opening time of 0.5 seconds is small. Further, during the execution of the second special game, the special game control means 150 instructs the state control means 180 to execute the opening of the second big prize opening 96 for 29 seconds at a predetermined timing. The second grand prize opening 96 is opened three times.

  When it is determined by the lottery means 120 that a special game is to be generated, the state control means 180 changes the special winning opening used depending on whether or not the short-time game is being executed. Specifically, when it is determined that the special game is generated by the lottery means 120 during execution of the short-time game, the state control means 180 controls the opening and closing of the second big prize opening 96, while the normal game is being executed. When the lottery means 120 determines that a special game is to be generated, the first grand prize winning port 66 is controlled to open and close. Specifically, during the first special game, the state control means 180 drives the first big prize opening solenoid 80 based on the opening instruction of the first big prize opening 66 sent from the special game control means 150. The opening / closing control of the first big prize opening 66 is executed, and the second big prize opening solenoid 92 is driven based on the opening instruction of the second big prize opening 96 sent from the special game control means 150 during the second special game. Then, opening / closing control of the second grand prize winning opening 96 is executed.

  When the special symbol stops at the short-time symbol, the specific game control means 160 executes the short-time game in which the variation time of the special symbol is shorter than that of the normal game after the special game ends. The specific game control means 160 determines whether the special game is generated during execution of the short-time game or whether it is determined to generate the special game during execution of the normal game. Set the number of executions or execution time of the short game to be performed after the end. At this time, if it is determined that the special game is generated during the execution of the short game, the specific game control means 160 changes the number of executions or the execution time of the short game after the special game from the normal game to the special game. It is set to be longer than the number of times the short-time game is executed after the transition or longer than the execution time.

  In this embodiment, when it is determined that the second special game is to be generated during execution of the short-time game, the execution count of the short-time game is set to 100 times. Further, when it is determined that the first special game is to be generated during the execution of the normal game, the execution count of the short-time game is set to four times. In this way, by changing the number of times a short-time game is executed according to the game state at the time of jackpot, effectively using the short-time game and effectively setting a step for allowing the player to win a game Can be realized and a new game can be realized. In this embodiment, the short-time game is set by defining at least two kinds of symbol variations. However, for example, by defining at least two execution times after the start of the short-time game, the short-time game is defined. It may be set. For example, the execution time of the short time game after the end of the first special game may be set to 30 seconds, and the execution time of the short time game after the end of the second special game may be set to 10 minutes.

  The pattern storage unit 140 stores a plurality of variation patterns of symbols. The pattern storage unit 140 holds a special symbol variation pattern and a decorative symbol variation pattern. The symbol determination unit 130 determines a variation pattern and a stop symbol from the start of variation of the special symbol to the end of variation according to the lottery result by the lottery unit 120. The stop symbol is a symbol to be displayed at the end of symbol variation.

  In the pachinko gaming machine 10, the lottery result by the lottery means 120 is displayed using the decorative design, and the special design does not play a role of production. Therefore, in the pachinko gaming machine 10 according to the present embodiment, the special symbol variation pattern mainly has a role of determining the variation display time of the decorative symbol from the standpoint of production. Used for

  The symbol determination means 130 determines the variation pattern and stop symbol of the decorative symbol according to the variation pattern and stop symbol of the special symbol. In the case of a big hit with a short-time symbol during a normal game, a short-time game, which is a precondition for acquiring the second special game, occurs after the first special game ends. If the first special game that is not expected to get a lot of balls is positioned as a step necessary to acquire the second special game, the first special game is very short enough that the player will not notice it. You may end it with. At this time, if a big hit with a short time symbol during a normal game, the first special game ends in an instant, so that the player feels that the short time game is suddenly started during the normal game. Therefore, for example, the symbol determining means 130 may explain to the player that the short-time game is started when the variable display is ended, or may select a decorative symbol constituting the display content to be notified. When the display control means 170 displays the content on the effect symbol display device 60, the player who sees the content can enhance the expectation for the short-time game executed after the display is completed.

  Normally, a short-time game is started after the end of the special game. In this embodiment, the first special game is completed in a short time, so that the player feels that the normal game has shifted directly to the short-time game. Have. Therefore, it is possible to attract the player's interest to the game by notifying the player that the short-time game will start in advance.

  FIG. 4 is a flowchart showing a basic process in the pachinko gaming machine. The entrance determination unit 110 determines whether the game ball enters the start port 62 (S10). The lottery means 120 determines whether or not to generate a special game for opening the first grand prize winning port 66 or the second big prize winning port 96 at least once based on the ball entering the starting port 62 (S12). When it is determined that a special game is to be generated by lottery, the special game determination means 125 determines the type of special game to be executed according to the game state whether or not the short-time game is being executed (S14). Subsequently, the special game control means 150 executes a special game (S16), and when the special game is accompanied by a short game, the specific game control means 160 executes a short game for a predetermined number of times after the special game is completed. (S16).

  FIG. 5 is a flowchart showing the special game determination process shown in S14 of FIG. First, the random number acquisition unit 122 acquires a random number for the big hit lottery, and the hit determination unit 124 determines whether or not to generate a special game based on the random number value (S30). If the random value does not generate a special game (N in S30), the special game determination process ends. On the other hand, when it is determined that a special game is to be generated (Y in S30), the special game determination means 125 determines whether or not the gaming state is a time-short game (S32). The short-time game is controlled by the specific game control means 160, and the special game determination means 125 may inquire whether or not the specific game control means 160 is in a short-time game.

  In the case of a big hit during a short-time game (Y in S32), the special game determination means 125 further determines whether or not the winning symbol is a so-called short-time symbol (S34). If it is a short time symbol (Y in S34), the special game determination means 125 selects the second special game as the special game to be executed (S36). If it is not a big hit during the short-time game (N in S32), and if the winning symbol is not a short-time symbol (N in S34), the special game determination means 125 selects the first special game as a special game to be executed (S38). ).

  In the above, this invention was demonstrated based on the Example. This embodiment is an exemplification, and it will be understood by those skilled in the art that various modifications can be made to the combination of each component and each processing process, and such modifications are also within the scope of the present invention. .

  In the embodiment, the specific game control means 160 has been described as an example of executing a short-time game in which the variation time of the special symbol is shortened as a specific game compared to during a normal game. For example, a specific game has a probability of occurrence of a special game. It may be a probability variation game that increases. When the special symbol stops at the symbol that generates the probability variation game (hereinafter referred to as “probability variation symbol”), the specific game control means 160 starts the probability variation game after the special game ends. The short time symbol and the probability variation symbol may be the same symbol or different symbols. Furthermore, there may be a plurality of time-saving symbols and probability variation symbols, and some of them may be common. When a player acquires a special game with a probability variation, the player has a chance to acquire the special game with a higher probability than the normal game after the special game ends.

  FIG. 6 is a flowchart showing a modification of the special game determination process shown in S14 of FIG. First, the random number acquisition means 122 acquires a random number for the big hit lottery, and the hit determination means 124 determines whether or not to generate a special game based on the random value (S50). If the random value does not generate a special game (N in S50), the special game determination process ends. On the other hand, when it is determined that a special game is to be generated (Y of S50), the special game determination means 125 determines whether or not the gaming state is in a probability variation game (S52). The probability variation game is controlled by the specific game control means 160, and the special game determination means 125 may inquire whether or not the specific game control means 160 is in the probability variation game.

  In the case of a big hit in the probability variation game (Y of S52), the special game determination means 125 further determines whether or not the winning symbol is a so-called probabilistic symbol (S54). If it is a probability variation symbol (Y in S54), the special game determination means 125 selects the second special game as a special game to be executed (S56). When it is not a big hit in the probability variation game (N in S52), and when the winning symbol is not a probability variation symbol (N in S54), the special game determination means 125 selects the first special game as a special game to be executed ( S58).

  In the special game determination process shown in FIG. 5, the second special game is selected when a big hit is made with a short-time game during a short-time game. However, when a big win is made during a short-time game, the second special game is selected regardless of the design. A game may be generated. As a result, the probability of continuously generating the second special game can be increased. Therefore, after acquiring the second special game, it is possible to realize a game with a large number of so-called consecutive changes. At this time, after the end of the second special game, the time-saving game of 100 time-savings may be given to the player, but whether or not the time-saving game occurs after the first special game is as described above. In addition, it may be determined by lottery. Thus, once the second special game is acquired while strictly setting the conditions for acquiring the second special game, it is possible to realize the gameability that is easy for the continuous game.

  Similarly, in the special game determination process shown in FIG. 6, the second special game is selected when a big hit is made in the probability variation game during the probability variation game, but in the case of a big hit during the probability variation game, regardless of the symbol The second special game may be generated. As a result, the probability of continuously generating the second special game can be increased. Therefore, after acquiring the second special game, it is possible to realize a game with a large number of consecutive changes.

  In the embodiment, the number of rounds of the first special game is 2 and the number of rounds of the second special game is 3. However, the number of rounds may be the same. That is, the state control means 180 keeps the number of times the first grand prize winning port 66 and the second grand prize winning port 96 are opened regardless of the difference in the maximum opening time between the first grand prize winning port 66 and the second grand prize winning port 96. It is good. For example, the number of rounds of the first special game and the second special game may be set to 3. Even in this case, the opening time for each round of the first big prize opening 66 in the first special game is about 0.5 seconds, and the opening time for each round of the second big prize opening 96 in the second special game is About 29 seconds. The interval between rounds may be set so that the first special game ends within a predetermined time, for example, 10 seconds. Thereby, the execution time of the first special game can be significantly shorter than the execution time of the second special game, and the special game can be changed. Further, by fixing the number of rounds of the first special game and the second special game, the state control means 180 does not need to change the number of times the special winning opening is opened according to the type of the special game, Since it is only necessary to control the interval between rounds, there is an advantage that opening / closing control can be facilitated.
