When there occurs winning in either of the lotteries, a winning game is executed, and when first winning occurs, the high-probability state is maintained until a prescribed number of times of the winning occur. Furthermore, a high-advantage winning game and a low-advantage winning game are prepared as the winning games, it can be decided that at least the high-advantage winning game may be executed in the winning of the first lottery, and in the winning of the second lottery, the execution of either of the high-advantage winning game or the low-advantage winning game can be decided. Then, a release time of the opening/closing start port is set long after the finish of the high-advantage winning game, and at the same time, after the finish of the low-advantage winning game based on the winning in the second lottery, the release time of the opening/closing start port is set short.

Description

  The present invention relates to a ball game machine such as a pachinko machine that plays a game by firing a game ball on a game board.

  When a game ball launched toward the game board enters the start gate, a lottery is conducted. When the lottery is won (winning), the normally closed big prize opening is opened to win. A ball game machine for executing a game is widely known. When a game ball enters the big prize opening, a predetermined number of game balls are paid out as prize balls. Therefore, in a winning game, a player can enter a number of prizes by putting a game ball into the opened big prize opening. It is possible to acquire a ball. In addition, as the types of winning (per win), hits that make it easy to put game balls into the big prize opening in the hit game (per high profit), and hits that make it difficult to put game balls into the big prize opening compared to high profits Also known is a ball game machine with (per low profit). Because there are differences in the number of prize balls that can be earned during a game depending on whether the type of hit is per high profit or low profit, not only is it expected to win, but more prize balls are obtained. It can be expected to be per unit of high profits that can be made, and the entertainment interest can be enhanced.

  In addition, with such a ball game machine, the probability of winning a lottery (winning probability) is set to a higher probability than usual when the winning game is completed with the intention of being able to acquire a large amount of prize balls in a short time. To be done. Furthermore, it has been proposed that once a hit occurs, the high probability state is continued until the number of hits reaches a predetermined number (for example, five times) (Patent Document 1). In other words, once a hit (per high profit or low profit) occurs, a high probability state is continued until a predetermined number of hits (per high profit or low profit) occurs, so that the hit is continuous in a short period of time. Since the possibility of doing (so-called continuous change) increases, it is possible to further enhance the amusement interest.

  However, even if the high probability state continues until a predetermined number of hits occurs, those hits may be unfortunately only low hits. In such a case, despite the fact that the lottery has been won many times (winning), it is possible that almost no prize balls can be obtained. there were.

  The present invention has been made to solve the above-described problems in the prior art, and in a ball game machine that maintains a high probability state until a predetermined number of hits occur, the predetermined number of hits is a low profit per unit. The purpose is to provide a technology that can suppress the situation.

In order to solve at least a part of the above-described problems, the bullet ball game machine of the present invention employs the following configuration. That is,
A fixed start opening provided in a state in which a game ball launched into the game area can enter,
An open / close-type start port that switches between an open state in which game balls launched into the game area can enter and a closed state in which game balls cannot enter;
A prize opening provided in the game area so as to be openable, and a predetermined amount of game balls are paid out by entering the game balls;
Lottery means for performing a lottery to determine whether or not a game ball has entered the fixed start opening or the openable start opening;
When the result of the lottery is the winning, the winning game execution means for opening the big prize opening and executing the winning game;
An opening time setting means for setting an opening time in which the opening-and-closing start port after the winning game is in the opened state to a short time or a long time longer than the short time;
When the winning probability in the lottery is a normal probability, the winning probability is set to a high probability higher than the normal probability, and the number of hits in the lottery with the high probability is set to a predetermined number. In the case of a ball game machine comprising: probability changing means for setting the hit probability to the normal probability,
The lottery means
When the result of the lottery is the winning game, the winning game is either a high profit game with a high profit for the player or a low profit game with a low profit for the player than the high profit game. Is a means of determining
If the result of the lottery resulting from entering the fixed start opening is the win, it is possible to decide to execute at least the high profit game.
When the result of the lottery resulting from entering the open / close starter is the win, it is possible to decide to execute either the high profit game or the low profit game And
The opening time setting means includes
When the result of the lottery resulting from the entry into the fixed start opening is the hit and the execution of the high profit profit game is determined, the opening / closing type after the high profit profit game ends. Set the opening time of the start port to the long time,
When the result of the lottery resulting from the entrance to the opening / closing start opening is the hit, and the execution of the game per high profit is determined, the opening / closing type after the game per high profit ends. When the opening time of the start opening is set to the long time and execution of the game per low profit is decided, the opening time of the openable start opening after the game per low profit is ended is shortened. It is set to time.

  In such a ball game machine of the present invention, a fixed start opening and an openable start opening are provided, and a lottery is performed because a game ball enters one of the start openings. , Hit or miss is determined. When the result of the lottery is a win, the winning game is performed with the big winning opening opened. In addition, when the winning probability of the lottery is a normal probability, the winning probability is set to a high probability, and the high probability is continued until the number of hits in the lottery with a high probability reaches a predetermined number. (Guaranteed). In addition, the winning game includes a game per high profit and a game per low profit. If the result of the lottery (first lottery) resulting from entering the fixed start opening is a win, If the winning game can be determined and the result of the lottery (second lottery) resulting from entering the opening-and-closing start port is a win, either the game per high profit or the game per low profit is selected. The execution of one hit game is determined. Note that the winning game for winning in the first lottery may be composed only of games per high profit, or may be composed of games per high profit and games per low profit as in the second lottery. When the result of the first lottery is a win and a high profit game is executed, the opening time of the open / close starter after the winning game is ended is made long. On the other hand, if the result of the second lottery is a win and a game per high profit is executed, the opening time of the open / close-type start port after the winning game ends is long, and the game per low profit is executed. In such a case, the opening time of the opening / closing start port after the end of the hit game is short.

  Here, “high or low profit for the player” in the present invention means, for example, that the number of game balls to be paid out to the player as a prize ball (which can be acquired by the player) is large or small. it can. In this case, the “game per low profit” may be a per game where the number of award balls that the player can acquire is smaller than the “game per high profit”, and includes a game that cannot acquire a prize ball. In addition, when a prize ball is paid out in proportion to the number of game balls that have entered the big prize opening, the possibility of entering the game ball into the big prize opening is reduced (for example, the opening time of the big prize opening) The number of prize balls that can be obtained by the player in the “game per low profit” can be made smaller than that in the “game per high profit”.

  According to the bullet ball game machine of the present invention having the above-described configuration, although the result of the lottery (second lottery) resulting from entering the opening / closing start port is a win, the execution of the game per low profit is determined. If the number of wins in the high probability state does not reach the predetermined number, the open probability of the open / close-type start port after the low-profit game ends is shortened while the lottery win probability remains high. Time. By making it difficult to enter the opening / closing start port in this way, the lottery state after the low profit per game ends with the lottery (first lottery) mainly due to entering the fixed start port. State. When the opening time of the open / close start port is set to be a long time, the lottery state is mainly composed of the lottery (second lottery) caused by entering the open / close start port. In the first lottery, if the execution of the high profit per game is determined when the win is made, it is possible to prevent the low profit per game from continuing.

  In addition, the low profit per game is executed before the number of hits reaches a predetermined number of times, so that the opening time of the open / close-type start opening is shortened with a high probability of winning the lottery (high probability) However, the rate of entrance to the start opening per unit time is low). As a result, compared to the case where a high probability and a lottery state mainly in the second lottery (a state where the entrance rate per unit time is high at the start opening) occurs continuously for a predetermined number of times, The duration of the high probability state can be secured for a long time, and the player's expectation can be maintained for a long time. In addition, among the predetermined number of hit games performed while the hit probability is high, the percentage of high profit per game is increased, and all of the predetermined number of hit games are low profit per game. If the possibility of becoming can be reduced, it becomes possible to further enhance the interest of the player.

  In addition, when a game per high profit is executed in the first lottery, after the game per high profit is completed, the opening time of the open / close starter is extended for a long time to enter the open / close starter. By increasing the frequency, it is possible to switch from the first lottery to the lottery state mainly composed of the second lottery. Then, in the second lottery, by including the execution of the game per low profit when winning, the game per low profit can be included in the predetermined number of games that are guaranteed to be executed in the high probability state. As a result, it is possible to moderate euphoria. And while restraining gambling moderately, as described above, by preventing the game per low profit from being continuously executed in a short time and ending the high probability state in a short time, Interest can also be maintained.

  In the above-described ball ball game machine of the present invention, when the result of the first lottery (the lottery resulting from entering the fixed start opening) is a win, the game selected from the high profit game or the low profit game While the execution of one hit game is determined, the probability that the game execution per high profit is determined may be set higher than the probability that the game execution per low profit is determined.

  If it does in this way, the game per low profit will be performed in the 2nd lottery (the lottery resulting from the entrance to the opening-and-closing start opening), and the opening-and-closing start opening after the game per low profit will be opened In the case where the time is short and the lottery state is mainly the first lottery with the high probability state, if the winning is in the first lottery, the game per high profit is more easily executed than the game per low profit. Therefore, it is possible to reduce the possibility that games per low profit will be played continuously.

  Further, in the above-described bullet ball game machine of the present invention, the probability that the execution of the game per high profit is determined when the result of the first lottery (the lottery resulting from entering the fixed start opening) is a win. May be set to be higher than the probability that the execution of the game per high profit is determined when the result of the second lottery (the lottery resulting from entering the opening / closing start port) is a win.

  According to such a configuration, when a game per low profit is executed in the second lottery, the opening time of the opening-and-closing start port after the game per low profit is ended is shortened and the second By switching from the lottery to the lottery state mainly based on the first lottery, the possibility that the next winning game will be a high profit per game compared to the case where the lottery state mainly based on the second lottery is continued. Can be increased. As a result, among the predetermined number of hit games that are performed while the hit probability is high, the proportion of high profit-per-play games is increased (suppresses that only low-per-profit games are played). be able to.

  Further, in such a ball game machine of the present invention, when a game per low profit is executed, the big winning opening is opened in such a manner that the game ball is difficult to enter compared to the case where a game per high profit is executed. It is good.

  Here, “a mode in which a game ball is difficult to enter” means, for example, (1) shortening the opening time of the grand prize opening or (2) opening and closing the grand prize opening multiple times. The number of times can be reduced, and (3) the opening range when opening the big prize opening can be reduced. Moreover, the aspect in which a game ball cannot enter is also included.

  In this way, if the opening mode of the big winning opening in the game per low profit is a mode in which the game ball is difficult to enter in comparison with the game per high profit, the number of prize balls paid out in the game per low profit (player) The number of prize balls that can be earned is less than games per high profit. Thereby, the game per low profit can be made a low game per game that is less profitable for the player than the high profit per game.

  According to the present invention, in a ball game machine that continues a high probability state until a predetermined number of hits occur, the predetermined number of hits continuously occur in a short time and only per low profit. Can be suppressed.

The mouth solenoid 31m, and further, the first symbol display device 28, the second symbol display device 32, and the like are connected via a relay terminal plate. These solenoids 17m and 31m, the first symbol display device 28, and the second These operations are also controlled by transmitting a signal toward the symbol display device 32.

  When the sub-control board 220 receives various commands from the main control board 200, the sub-control board 220 analyzes the contents of the command and produces a game according to the result. That is, a command for designating display contents is transmitted to the effect control board 230 that performs display control of the effect display device 27 described above, the amplifier board 224 that drives the speaker 5y, various decorative LEDs and lamps 4b to 4f. The game is rendered by transmitting a drive signal to the decorative drive board 226 that drives the game. The operation signal of the operation switch SW described above is input to the sub control board 220 via the effect button board 228.

  The payout control board 240 is responsible for various controls relating to so-called ball rental and prize ball payout. For example, when the player operates the ball lending switch 5b or the return switch 5c provided in the above-described upper plate part 5, the operation signal is transmitted from the ball lending display board 242 via the payout control board 240. Is transmitted to. The ball lending device 13 pays out a ball while communicating data with the payout control board 240. Further, when the main control board 200 transmits a prize ball payout command, the payout control board 240 receives this command and sends a drive signal to the payout motor 109m to pay out the prize ball.

B. Overview of the game:
Next, an outline of a game performed in the pachinko machine 1 of the present embodiment having the above-described configuration will be briefly described.

  In the pachinko machine 1 of the present embodiment, a game is performed as follows. First, when a player throws a game ball into the recess of the upper plate portion 5 and rotates the launch handle 8, the game balls thrown into the upper plate portion 5 are supplied to the launcher unit 12 one by one, The game area 11 is fired as described above with reference to FIG. The strength at which the game ball is launched can be adjusted by the rotation angle of the launching handle 8, and the player can aim the game ball by changing the rotation angle of the launching handle 8.

  When the launched game ball passes through either the normal symbol operation left gate 36 or the normal symbol operation right gate 37 provided on the left and right of the game area 11, the first symbol display provided at the lower left of the effect display device 27. In the device 28, the normal symbol variation display is started. As described above with reference to FIG. 4, the normal symbol display unit 29 is provided in the first symbol display device 28, and the normal symbol display unit 29 includes the normal symbol LED 29 a and the universal symbol hold display LED 29 b. Yes. Of these, the normal symbol LED 29a is used to display the variation of the normal symbol.

  FIG. 7 (a) is an explanatory diagram conceptually showing how ordinary symbols are variably displayed. In the pachinko machine 1 according to the present embodiment, the normal symbol LED 29a is repeatedly blinked to display the variation of the normal symbol. In FIG. 7, the state in which the normal symbol LED 29a is lit is represented by a radial solid line, and the state in which the normal symbol LED 29a is lit is represented by a broken line. Then, after repeating blinking for a predetermined time, when the normal symbol LED 29a stops in a lighting state, it becomes a hit of the normal symbol, and the second start port 17b (starting below the start port unit 17 is started). Mouth) is open for a predetermined opening time. On the contrary, when it stops in a light-off state, it will be out of the normal design and the second start port 17b will not open. If the game ball passes through the normal symbol operation left gate 36 or the normal symbol operation right gate 37 during the normal symbol variation display, the passage of the game ball is stored as a normal symbol hold (ordinary symbol hold). After the current normal symbol variation display is completed, the variation display is performed. It is possible to store up to four common figure holds, and the number of reserved normal symbols stored (the number of common figure holds) is displayed by the common figure hold display LED 29b.

  FIG. 7B is an explanatory view showing a state in which the number of universal symbols is displayed by the universal symbol hold display LED 29 b provided in the first symbol display device 28. When there is no general map hold (that is, when there is no general map hold), both of the two general map hold display LEDs 29b are turned off. When there is one common map hold, the left general map hold display LED 29b is turned off and the right general map hold display LED 29b is lit. When there are two common map holds, the left general map hold display LED 29b is lit in addition to the right general map hold display LED 29b. Next, when there are three common map holds, the right general map hold display LED 29b blinks and the left general map hold display LED 29b lights. Further, when the number of normal map hold increases to the upper limit of four, the left and right general map hold display LEDs 29b blink. As described above, the normal symbol display unit 29 can display 0 to 4 universal symbol hold numbers by turning on, off, or blinking the two universal symbol hold display LEDs 29b.

  Further, as described above with reference to FIG. 3A, the first symbol display device 28 is provided with the first special symbol display unit 30, and the first special symbol (first special symbol) is variably displayed. It is possible. Further, as shown in FIG. 3B, the second special symbol display unit 33 provided in the second symbol display device 32 can display the second special symbol (second special symbol) in a variable manner. . Of these, the first special symbol corresponds to the first start port 17a, the second special symbol corresponds to the second start port 17b, and the first special symbol or the second special symbol corresponds to the corresponding start port. When a game ball enters, the change display starts. As described above, the first special symbol display unit 30 and the second special symbol display unit 33 have the same configuration, and accordingly, the first special symbol and the second special symbol are displayed in a variable manner in the same manner. Stop display after performing.

  In addition, even when a game ball enters the first start port 17a or the second start port 17b, the corresponding special symbol cannot be displayed immediately (for example, any special symbol is being displayed in a variable manner). In the case of a game or a big hit game, etc.), the maximum number of balls entered into the first starting port 17a is stored as a first special symbol hold (first special figure hold). Up to four balls entered into the 2 starting port 17b are stored as the second special symbol hold (second special figure hold). The number of the first special figure hold (first special figure hold number) is displayed by the first special figure hold display LED 30b, and the number of the second special figure hold (second special figure hold number) is indicated by the second special figure hold number. Displayed by the figure hold display LED 33b. The manner in which the number of special symbols held using the first special figure hold display LED 30b or the second special figure hold display LED 33b is displayed is the same as that of the general figure hold display LED 29b shown in FIG. 7B. Therefore, the description is omitted here.

  FIG. 8 is an explanatory diagram conceptually showing a stop display mode of the first special symbol or the second special symbol. Since the first special symbol and the second special symbol have the same variation display and stop display, the two symbols are simply referred to as a special symbol without distinguishing between the two. As described above with reference to FIG. 3, each of the first special symbol display unit 30 and the second special symbol display unit 33 is composed of seven LEDs, and the special symbols are displayed by lighting them. As shown in FIG. 8, in the pachinko machine 1 of the present embodiment, as a special symbol stop display mode (stop symbol), four types of jackpot symbols (A, B, C, D) and two types of symbols are displayed. There are 6 different symbols in total. In the first symbol display device 28 and the second symbol display device 32, each of the seven LEDs (the first special symbol LED 30a and the second special symbol LED 33a) blinks for a predetermined variation time to display the variation of the special symbol. When a predetermined fluctuation time has elapsed, one of the stop symbols is stopped and displayed. Then, when any of the jackpot symbols (A to D) is stopped and displayed, the jackpot game in which the jackpot 31d is opened (a jackpot is generated).

  The big hit game is configured such that a round game is repeated a plurality of times when the special winning opening 31d is opened and the opening time elapses or when a predetermined number of game balls are entered. The player can acquire the number of prize balls corresponding to the number of entered balls by causing the game balls to enter the open large winning opening 31d. Thus, the big hit game in which the game ball can enter the big winning opening 31d is an advantageous game state for the player. Further, in the pachinko machine 1 of the present embodiment, four types of big hit games (A, B, C, D) having different opening modes of the big winning opening 31d (possibility of game balls entering the big winning opening 31d) are provided. Which jackpot game (A to D) has been set and is started corresponds to the jackpot symbol (A to D) displayed in a stopped state. Therefore, the number of prize balls that the player can acquire during the big hit game depends on which of the four types of big hit symbols (A to D).

  FIG. 9 is an explanatory diagram showing the contents of the four types of jackpot games set in the pachinko machine 1 of the present embodiment. The four types of big hit games differ in the opening time of the special winning opening 31d, the prescribed number of balls, or the number of times that the large winning opening 31d is opened (the number of rounds). First, in the “big hit game A” corresponding to the big hit symbol A, the opening time of the big winning opening 31d is set to a long time (here, 30 seconds), and the prescribed number of balls is set to a large number (here, 10). Therefore, it is easy to enter a large number of game balls into the special winning opening 31d, and the round game is repeated up to 15 times, so that the player can acquire a large amount of prize balls. Next, in the “big hit game B” corresponding to the big hit symbol B, the round game with the long opening time (30 seconds) of the big winning opening 31d and a large number of prescribed pitches (10) is repeated up to five times. The player can obtain a lot of prize balls although the number is smaller than the above-mentioned jackpot game A. Subsequently, in the “big hit game C” corresponding to the big hit symbol C, the number of rounds is five as in the big hit game B, but the opening time of the big winning opening 31d is short (here, 0.1 second). Since the set number of balls is set to a small number (two here), it is difficult in the first place to enter the game balls into the large winning opening 31d. The possibility that a game ball will enter is very low. Therefore, the player can hardly obtain a prize ball. Furthermore, in the “big hit game D” corresponding to the big hit symbol D, the round game with the short winning opening 31d is short (0.1 seconds) and the specified number of balls is small (two) is repeated twice. It is set to be more difficult to obtain a prize ball than the above-mentioned jackpot game C (a player cannot practically obtain a prize ball). In the following, the jackpot game A is referred to as “15R multiplayer hit”, the jackpot game B is referred to as “5R multiplayer hit”, the jackpot game C is referred to as “5R multiplayer hit”, and the jackpot game D Is sometimes referred to as “2R small ball hit”. The jackpot games A and B in this embodiment correspond to the “game per high profit” of the present invention, and the jackpot games C and D in the present embodiment correspond to the “game per low profit” in the present invention. Yes.

  Further, in the pachinko machine 1 according to the present embodiment, a normal probability and a high probability higher than the normal probability are provided as probabilities that the big hit symbols (A to D) are stopped and displayed (big hit probability). As will be described in detail later, when the jackpot symbol (A to D) is stopped and displayed in a normal probability state, the jackpot probability is set to a high probability thereafter, and in the state set to the high probability, When a jackpot game is played a predetermined number of times (for example, five times) (the number of times the jackpot symbol is stopped and displayed reaches a predetermined number), the normal probability is returned (the limiter is activated).

  As described above, in accordance with whether the first special symbol or the second special symbol is variably displayed and stopped, the effect display device 27 uses various effect symbols (identification symbols 27a, 27b, 27c, background symbols 27d, etc.). Will be performed. FIG. 10 is an explanatory view illustrating an aspect of the effect performed by the effect display device 27. As described above with reference to FIG. 4, three identification symbols 27 a, 27 b and 27 c are displayed on the liquid crystal display screen constituting the effect display device 27. When the variation display of the special symbol is started in either the first symbol display device 28 or the second symbol display device 32 described above, these three identification symbols 27a, 27b, and 27c are simultaneously displayed on the effect display device 27. Start the variable display. In the present embodiment, a design in which nine numbers from “1” to “9” are designed as identification symbols is prepared. Note that the identification symbol may be a symbol, character, graphic, symbol, or the like as a design in addition to numerals, as long as the player can identify the type.

  FIG. 10A conceptually shows how the three identification symbols 27a, 27b, and 27c are variably displayed. When a predetermined time elapses after the variable display is started, the left identification symbol 27a is first stopped and displayed in any one of “1” to “9”, and then the right identification symbol 27c is stopped and displayed. The middle identification symbol 27b is stopped and displayed. The combination of the three identification symbols 27a, 27b, and 27c that are stopped and displayed on the effect display device 27 is a special symbol (first special symbol) that is stopped and displayed on the first symbol display device 28 or the second symbol display device 32 described above. Or it is comprised so that it may interlock | cooperate with the stop display mode (stop symbol) of a 2nd special symbol. For example, when the first special symbol or the second special symbol stops at the “big hit symbol”, the three identification symbols 27a, 27b, and 27c of the effect display device 27 are stopped and displayed at the same symbol. In addition, when the first special symbol or the second special symbol is stopped at the “off symbol”, the three identification symbols 27a, 27b, and 27c are stopped and displayed in a combination that does not align with the same symbol.

  Thus, the special symbols displayed on the first symbol display device 28 or the second symbol display device 32 and the three identification symbols 27a, 27b, and 27c displayed on the effect display device 27 correspond to each other. When the changing first special symbol or second special symbol is stopped and displayed, the three identification symbols 27a, 27b and 27c are also stopped and displayed. Moreover, as shown in FIG. 2, the effect display device 27 is provided at a position that is more noticeable than the first symbol display device 28 and the second symbol display device 32, and the display screen is large and the display contents can be understood. Since it is easy, a player usually plays a game while viewing the screen of the effect display device 27. Therefore, as shown in FIG. 10B, the left identification symbol 27a that is first stopped and displayed on the display screen of the effect display device 27 and the right identification symbol 27c that is subsequently stopped and displayed are the same symbol. In such a case, the player may watch the change of the symbol as if the middle identification symbol 27b that is stopped and displayed last is also stopped at the same symbol and the so-called jackpot game is started. In this way, the effect performed in a state where the two identification symbols are stopped with the same symbol (a mode that can be a big hit symbol) and the last identification symbol is variably displayed is called “reach effect”. It is possible to enhance the entertainment interest of the game by generating.

C. Control details of pachinko machine:
Below, in order to implement | achieve the game mentioned above, the control content which the pachinko machine 1 of a present Example is performing is demonstrated in detail.

C-1. Game control processing:
FIG. 11 is a flowchart showing a rough flow of a game control process performed by the CPU 201 mounted on the main control board 200 to control the progress of the game. As shown in the figure, in the game control process, each process such as a prize ball-related process, a normal symbol game process, a second start opening closing process, a special figure hold-related process, a special symbol game process, and a big hit game process are repeatedly executed. ing. The time required for one round of processing is about 4 msec. Therefore, these various types of processing are repeatedly executed about every 4 msec. Then, during these processes, various commands are transmitted from the main control board 200 to the various control boards including the sub control board 220. By doing so, the game of the entire pachinko machine 1 proceeds, and the sub-control board 220 controls the production in accordance with the progress of the game. The game control process performed by the CPU 201 mounted on the main control board 200 will be described below according to the flowchart.

  When starting the game control process, the CPU 201 mounted on the main control board 200 performs a process (pay ball related process) for paying out a game ball as a prize ball (S50). In this process, among the various switches connected to the main control board 200, the switches related to the winning of the game ball (the first starting port switch 17s, the second starting port switch 17t, the big winning port switch 31s, etc.) It is detected whether or not a game ball has entered. When a game ball is detected, the number of prize balls to be paid out is calculated, and then a prize ball number designation command is transmitted to the payout control board 240. When the payout control board 240 receives the prize ball number designation command transmitted from the main control board 200, the payout control board 240 interprets the content of the command, and according to the result, a drive signal is sent to the payout motor 109m mounted on the payout device (not shown). Is sent out to actually pay out a prize ball.

  When the CPU 201 of the main control board 200 performs a process related to the prize ball (S50), this time, whether or not to perform the normal symbol game process, that is, whether to perform the process of variably displaying the normal symbol and stopping and displaying it It is determined whether or not (S100). This determination is made by detecting whether or not the second start port 17b is open. If the second start port 17b is not in the open state, it is determined that the normal symbol game process is performed (S100: yes), and if the second start port 17b is in the open state, it is determined that the normal symbol game process is not performed ( S100: no). When it is determined that the normal symbol game process is to be performed (S100: yes), the normal symbol game process described below is performed (S150). On the other hand, when it is determined that the normal symbol game process is not performed (S100: no), the normal symbol game process (S150) is omitted.

  In the normal symbol game process (S150), the following processes are mainly performed. First, it is determined whether or not a normal symbol hold (ordinary symbol hold) exists (whether or not it is “0”). As described above, the common figure hold is stored when the game ball passes through the normal symbol operation gates 36 and 37, and in this embodiment, the upper limit value of the number of holds is “4”. Then, based on the result of the lottery drawing of the normal symbol, it is determined whether the normal symbol is to be stopped and displayed with the winning symbol (see FIG. 7A) or stopped with the off symbol. Subsequently, after the normal symbol fluctuation display time is set, the normal symbol fluctuation display is started. When the normal symbol variation display time elapses, the normal symbol is stopped and displayed with the determined symbol. At this time, when the normal symbol hit symbol is stopped and displayed, the second start port solenoid 17m is turned off. The second starting port 17b is opened by operating and opening the pair of blade pieces 17w provided in the second starting port 17b outward (see FIG. 5B).

  When the normal symbol game process is completed as described above, it is determined whether or not the second start port 17b is in an open state (S190). And when it is an open state (S190: yes), the process for returning the 2nd starting port 17b from an open state to a closed state (2nd starting port closing process) is performed (S200). On the other hand, when the 2nd starting port 17b is not an open state (S190: no), since it is not necessary to perform a 2nd starting port closing process, it abbreviate | omits.

  In the second starting port closing process (S200), when any of the following conditions is satisfied, that is, the opening time of the second starting port 17b has elapsed, or a prescribed number of games are stored in the second starting port 17b. It is determined whether any of the conditions for entering the ball is satisfied, and when any of the conditions (starting port opening end condition) is satisfied, the opened second starting port 17b is closed. Performs variable control processing. The opening time of the second start port 17b is normally set to a short time (for example, 0.5 seconds). However, if the opening extension flag described later is set to ON, the opening time is long ( For example, it is extended to 5 seconds). On the other hand, when the opening time of the second start port 17b has not elapsed and the number of balls entering the second start port 17b has not reached the specified number (when the start port opening end condition is not satisfied), The second start port closing process (S200) is terminated with the second start port 17b open. When the second start port closing process is thus completed and the process returns to the game control process, a special figure holding related process (S250) described below is started.

C-2. Special figure hold related processing:
FIG. 12 is a flowchart showing special figure hold-related processing. In the special figure hold related process (S250), first, it is determined whether or not a game ball has entered the first start port 17a (S252). When a game ball enters the first starting port 17a (S252: yes), the number of reserved special symbols (the number of first special figure reserved) reaches the upper limit ("4" in this embodiment). It is determined whether or not (S254). If the first special figure reservation number has not reached the upper limit (S254: no), a lottery random number is acquired (S256). Here, as a lottery random number, in order to determine a jackpot lottery random number used to perform a jackpot lottery described later, or a symbol to be stopped and displayed on the first special symbol display unit 30 (or the second special symbol display unit 33). Get a random number, such as a symbol-determining random number to be used. Subsequently, these lottery random numbers are stored in the RAM 203 mounted on the main control board 200 as the first special figure hold (S258).

  When the first special figure hold is stored in this manner (S258), "1" is added to the first special figure hold number (S260). On the other hand, when a game ball does not enter the first start port 17a (S252: no), or when the first special figure reservation number has reached the upper limit (here, “4”) ( S254: yes), a series of processing (S256 to S260) for obtaining a lottery random number or storing the lottery random number as the first special figure hold is omitted.

  When the process related to the first special figure hold is completed as described above, the process related to the second special figure hold (the process related to the second special figure hold is started. The process related to the second special figure hold is performed on the first start port 17a. The above-described processing relating to the holding of the first special figure is processing for the second starting port 17b.Hereinafter, a brief description will be given first, whether or not a game ball has entered the second starting port 17b. (S264), if a game ball has entered the second start port 17b (S264: yes), whether the second special figure holding number has reached the upper limit (“4” in this embodiment) If the second special figure holding number has not reached the upper limit (S266: no) as a result, a lottery random number (a big hit lottery random number, a symbol determination random number, etc.) is acquired (S268). ), With these random numbers as the second special figure hold, the main control board 200 It is stored in the mounted RAM 203 (S 270), and “1” is added to the second special figure reservation number (S 272) On the other hand, there is no game ball entering the second start port 17 b (S 264). : No), if the number of second special figure hold has reached the upper limit (here, “4”) (S266: yes), the lottery random number is acquired or the lottery random number is stored as the second special figure hold A series of processing (S268 to S272) is omitted.

  When the processes relating to the first special figure hold and the second special figure hold are finished as described above, the special figure hold related process shown in FIG. 12 is finished, and the process returns to the game control process of FIG. When returning from the special figure hold-related process, the game control process starts a special symbol game process (S300) described below.

C-3. Special design game processing:
13 and 14 are flowcharts showing the special symbol game process. When starting the special symbol game process, the CPU 201 of the main control board 200 first determines whether or not a big hit game is being played (S302). If the game is a big hit game (S302: yes), the special game process is terminated as it is, and the process returns to the game control process of FIG. On the other hand, if it is not a big hit game (S302: no), it is determined whether either the first special figure or the second special figure is changing (S304). As described above with reference to FIG. 3, the pachinko machine 1 of the present embodiment is provided with the first symbol display device 28 and the second symbol display device 32, and in the first symbol display device 28, the first special symbol of FIG. Fluctuation display is possible, and the second symbol display device 32 can perform fluctuation display of the second special figure.

  If neither the first special figure nor the second special figure is changing (S304: no), it is during the time for displaying the first special figure or the second special figure with the stop symbol (the special symbol stop display time). Whether or not (S306). In other words, in both the first special figure and the second special figure, a stop display time is provided as a confirmation time for the player to confirm the stopped and displayed symbols for a period of time after the symbol change is stopped and displayed. Therefore, it is determined whether or not it is during the stop display time. If neither the first special figure nor the second special figure is variably displayed and the special symbol stop display time has elapsed (S306: no), the special symbol variability display is started. For this purpose (special drawing fluctuation display process) is started (S310).

  FIG. 15 is a flowchart showing the first half of the special figure variation display process. FIG. 16 is a flowchart showing the latter half of the special figure variation display process. As shown in the figure, in the special figure variation display process, first, it is determined whether or not the second special figure reservation number is "0" (S3100). If the number of second special figure hold is not “0” (S3100: no), it can be determined that at least one second special figure hold is stored. The second special figure hold stored in the oldest (that is, the jackpot lottery random number or the symbol determination random number stored as the second special figure hold) is read from the inside (S3102).

  On the other hand, if the second special figure hold number is “0” (S3100: yes), it is next determined whether or not the first special figure hold number is “0” (S3104). If the number of first special figure hold is not “0” (S3104: no), it can be determined that at least one of the first special figure hold is stored. The first special figure hold stored in the oldest (that is, various lottery random numbers stored as the first special figure hold) is read from the inside (S3106). On the other hand, if the first special figure hold number is “0” (S3104: yes), the second special figure hold number is already determined to be “0”. Since it can be determined that neither the second special figure hold nor the second special figure is stored, there is no need to start the display of the fluctuation of the first special figure or the second special figure. Therefore, the special figure variation display process of FIGS. 15 and 16 is terminated, and the process returns to the special symbol game process shown in FIGS. 13 and 14.

  As described above, in the special figure variation display process, it is first determined whether or not the second special figure hold is stored (S3100), and only when the second special figure hold is not stored (S3100). : Yes), it is determined whether or not the first special figure hold is stored. Therefore, when both the first special figure hold and the second special figure hold are stored, the second special figure hold is always read in preference to the first special figure hold (second special figure hold). The first special figure hold is read out only when the second special figure hold is not stored.

  When either the first special figure hold or the second special figure hold is read as described above (S3102 or S3106), it is determined whether or not the high probability flag is set to ON (S3108). . As described above, in the pachinko machine 1 according to the present embodiment, the probability that the special symbol (the first special symbol or the second special symbol) is stopped and displayed with the big hit symbol (A to D) (the big hit probability) is the normal probability, Alternatively, it is possible to set a high probability higher than the normal probability. The high probability flag is a flag that is set to ON when the big hit probability is set to a high probability, and a predetermined address of the RAM 203 mounted on the main control board 200 is assigned as the high probability flag. The CPU 201 of the main control board 200 determines whether or not the current jackpot probability is high from the setting status of the high probability flag. If the high probability flag is not set to ON (S3108: no), the normal probability big hit lottery table is selected (S3120). If the high probability flag is set to ON (S3108: yes), A big hit lottery table for high probability is selected (S3122). Here, the big hit lottery table is a table in which a lottery result of “big hit” or “out” is set in association with the big hit lottery random number, and is stored in advance in the ROM 202 of the main control board 200.

  FIG. 17 is an explanatory diagram illustrating a big hit lottery table stored in the pachinko machine 1 according to the present embodiment. FIG. 17A shows a jackpot lottery table for normal probability, and FIG. 17B shows a jackpot lottery table for high probability. As shown in the drawing, each of the big hit lottery tables is associated with a big hit lottery random number from “0” to “630” with either “big hit” or “out” lottery results. As is clear from comparison between FIG. 17A and FIG. 17B, the high probability big hit lottery table shown in FIG. 17B has the normal probability shown in FIG. The lottery result of “big hit” is set to a larger number of random numbers than the big hit lottery table. Specifically, the high probability jackpot lottery table is set to obtain a “big hit” lottery result with a probability of about 8.8, whereas the normal probability jackpot lottery table. The table is set so that a “big hit” lottery result can be obtained with a probability of about 1 in 52.6. Therefore, when the big hit lottery is performed using the high probability big hit lottery table of FIG. 17B, the big hit lottery is performed using the normal probability big hit lottery table of FIG. 17A. However, a “big hit” lottery result will be obtained with a high probability. It should be noted that the fact that the big win lottery result is obtained is also expressed as “a big win occurs”.

  Subsequently, in the special figure fluctuation display process of FIG. 15, the big hit lottery random number read as the first special figure hold or the second special figure hold is referred to as “big hit” with reference to the big hit lottery table selected in the process of S3120 or S3122. It is determined whether the random number is an associated random number (whether the jackpot lottery result is a jackpot) (S3124). And when it is judged that the result of the big hit lottery is a big hit (when the big hit is generated) (S3124: yes), the big hit symbol to be stopped and displayed from the above-mentioned four types of big hit symbols (A to D). The process of determining is performed (S3126). This process is performed by using a symbol determination random number (S3102 or S3106) read as the first special symbol hold or the second special symbol hold and referring to a table called a big hit symbol determination table. In the pachinko machine 1 of the present embodiment, the big hit symbol determination table to be referred to differs depending on whether it is the first special figure or the second special figure.

  FIG. 18 is an explanatory diagram illustrating a jackpot symbol determination table. FIG. 18A shows a jackpot symbol determination table for the first special symbol, and FIG. 18B shows a jackpot symbol determination table for the second special symbol. These jackpot symbol determination tables are stored in advance in the ROM 202 of the main control board 200. As shown in the drawing, in the jackpot symbol determination table, any one of four types of jackpot symbols (A to D) is associated with the symbol determination random numbers “0” to “99”. In the process of S3126, referring to an appropriate jackpot symbol determination table depending on whether the symbol is the first special symbol or the second special symbol, the symbol determination random number read as the first special symbol hold or the second special symbol hold is used. The associated symbol is determined as a jackpot symbol to be stopped and displayed. As described above, since the four types of jackpot symbols (A to D) correspond to the four types of jackpot games (A to D), respectively (see FIG. 9), when the jackpot symbol is determined. At the same time, the contents of the jackpot game to be executed (the opening time of the big winning opening 31d, the prescribed number of balls entered, and the number of rounds) are also determined.

  In the jackpot symbol determination table for the first special symbol shown in FIG. 18A, the jackpot symbol A is set to “0 to 39” (40%) among the symbol determination random numbers “0 to 99”, A jackpot symbol B is set for "40 to 79" (40%), a jackpot symbol C is set for "80 to 89" (10%), and a jackpot symbol D is set for "90 to 99" (10%). Is set. For this reason, when the big hit lottery based on the first special figure hold becomes “big hit”, either the big hit symbol A or the big hit symbol B is easily determined as the big hit symbol to be stopped (80% of the total). , There is a high possibility that a jackpot game ("15R multi-ball per hit" or "5R multi-ball per win") in which a player can obtain many prize balls will be executed (the possibility of becoming a high profit per game is low) More likely to be a game per profit).

  On the other hand, in the jackpot symbol determination table for the second special symbol shown in FIG. 18B, the jackpot symbol A is set to “0 to 19” (20%) among the symbol determination random numbers “0 to 99”. "20-39" (20%) is set to jackpot symbol B, "40-69" (30%) is set to jackpot symbol C, and "70-99" (30%) is set to jackpot Symbol D is set. Compared with the jackpot symbol determination table for the first special symbol of FIG. 18 (a), the jackpot symbol determination table for the second special symbol of FIG. 18 (b) is a symbol determination random number of “0 to 99”. The ratio of jackpot symbol A and jackpot symbol B is low (40% of the total), and the ratio of jackpot symbol C and jackpot symbol D is high (60% of the total). Therefore, when the big hit lottery based on the second special figure hold becomes “big hit”, either the big hit symbol C or the big hit symbol D is easily determined as the big hit symbol, and it is difficult for the player to win the winning ball. There is a high probability that a big hit game (“5R small ball hit” or “2R small ball hit”) is executed (the possibility of becoming a low profit game is higher than the possibility of becoming a high profit game).

  In this way, referring to the appropriate jackpot symbol determination table depending on whether it is the first special symbol or the second special symbol, when one of the four types of big bonus symbols (A to D) is determined, the determination is made. The jackpot symbol is stored as a symbol to be stopped (stop symbol) (S3128).

  The case where the jackpot lottery result is a jackpot (a jackpot has occurred) has been described (S3124: yes). On the other hand, when the result of the big hit lottery is out (S3124: no), refer to the out symbol determination table (not shown) and determine one of the two types of out symbol (see FIG. 8). (S3130). Similarly to the jackpot symbol determination table shown in FIG. 18, the loss symbol determination table is a table in which one of two types of loss symbols is associated with the symbol determination random number (“0 to 99”). Pre-stored in the ROM 202 of the control board 200. In addition, about the off symbol determination table, it is common in the 1st special figure and the 2nd special figure. In the processing of S3130, the symbol associated with the symbol determination random number read as the first special symbol hold or the second special symbol hold is determined as the off symbol to be stopped and displayed with reference to such a deviating symbol determination table. Further, the determined symbols determined in this way are stored as stop symbols (S3128).

  Since the big hit lottery for determining the big hit or miss is executed by the CPU 201 of the main control board 200, the CPU 201 mounted on the main control board 200 of this embodiment corresponds to the “lottery means” of the present invention. doing.

  Processing to determine the mode (variation pattern) for variably displaying the special symbol (first special symbol, second special symbol) after storing the symbol (stop symbol) to be stopped and displayed according to the result of the big hit lottery as described above (Variation pattern determination processing) is started (S3140). Note that even if the special symbol is variably displayed, it is simply displayed by switching the plurality of types of display modes shown in FIG. 8 one after another. Therefore, the special symbol variation pattern is substantially different from the special symbol. It corresponds to the time to display (variation time). However, as described above, in the pachinko machine 1 according to the present embodiment, the variation display of the first special figure or the second special figure performed by the first symbol display device 28 or the second symbol display device 32 and the effect display device 27. Since the variation display of the identification symbols 27a, 27b, and 27c to be performed is linked to each other, when the variation pattern of the special symbol is determined, the time during which the identification symbols 27a, 27b, and 27c are variably displayed is determined. Then, the CPU 221 of the sub-control board 220 determines the contents of the symbol variation effect for variably displaying the identification symbols 27a, 27b, and 27c on the screen of the effect display device 27 within the range of the variation display time. ing.

  In the variation pattern determination process, it is determined whether or not the result of the big hit lottery is a big hit from among a plurality of variation patterns (variation times) stored in advance in the ROM 202 of the main control board 200, and whether or not the above-described reach effect is performed. Any variation pattern is determined based on whether or not a variation shortening flag, which will be described later, is set to ON. For example, when the result of the big hit lottery is a big hit, it is common to perform a reach effect on the effect display device 27, and in order to secure the reach effect time, a variation pattern having a long variation time is determined. Further, as will be described in detail later, in the pachinko machine 1 of the present embodiment, when the release extension flag is set to ON (the opening time of the second start port 17b is long), the fluctuation reduction flag is set to ON, Since the variation time of the special symbol is shortened, if the variation shortening flag is ON, a variation pattern having a short variation time is determined as compared to when the variation shortening flag is OFF.

  When the variation pattern determination process is completed, it is determined whether or not the jackpot lottery performed previously is based on the second special figure hold (S3142). And when it is the big hit lottery based on the 2nd special figure reservation (S3142: yes), after starting the fluctuation display of the 2nd special figure on the 2nd symbol display device 32 (S3144), the 2nd special figure reservation number Then, “1” is subtracted from (S3146). On the other hand, when the big hit lottery was not performed based on the second special figure hold, that is, the big hit lottery based on the first special figure hold (S3142: no), the first symbol display device 28 After the variable display of the first special figure is started (S3148), "1" is subtracted from the first special figure reservation number (S3150).

  After subtracting “1” from the second special figure reservation number or the first special figure reservation number (S3146 or S3150), the type of variation pattern of the special symbol (first special symbol or second special symbol) or the special symbol A variation start command (a variation pattern designation command and a stop symbol designation command) for designating a stop symbol or the like is transmitted to the sub-control board 220 (S3152). When the CPU 221 mounted on the sub-control board 220 receives the change start command, the CPU 221 selects an identification symbol to be stopped and displayed on the effect display device 27 based on the stop symbol designation command, and displays an effect based on the variation pattern designation command. A variation pattern (effect pattern) of the identification symbol in the device 27 is selected. Then, the symbol variation effect display is executed by variably displaying the identification symbols 27a, 27b, and 27c on the display screen of the effect display device 27 according to the selected effect pattern.

  When the CPU 201 of the main control board 200 transmits the change start time command, the special figure change display process shown in FIGS. 15 and 16 is terminated, and the process returns to the special symbol game process shown in FIGS. Here, as described above, in the special figure variation display process, even if the first special figure hold and the second special figure hold are alternately generated and stored, all the second special figure hold is digested. Until then, the first special figure hold is not digested (the special symbol variation display based on the ball entering the first start port 17a is performed) (S3100 to S3106). That is, in the present embodiment, a priority changing function for prioritizing the second special symbol over the first special symbol is provided. Therefore, if the release extension flag is set to ON (the opening time of the second start port 17b is long) and it is easy to enter the second start port 17b, the second special figure hold frequently occurs. A game mainly composed of the second special figure hold will be performed. On the other hand, when the opening extension flag is set to OFF (the opening time of the second start port 17b is short), the fixed first type that can always enter the ball than the openable second start port 17b. Since there is a high possibility of entering the starting port 17a, a game mainly composed of the first special figure hold is performed.

  In the above, when the special symbol game process shown in FIG. 13 and FIG. 14 is started, it is not in the big hit game (S302: no), and both the first special figure and the second special figure are variably displayed. The processing when it has been determined that it is not (S304: no) has been described. On the other hand, if it is determined that either the first special figure or the second special figure is changing (S304: yes), although it is not during the big hit game (S302: no), the special symbol has already been established. This corresponds to the case where the fluctuation pattern of the first special figure or the second special figure is determined and the fluctuation of the first special figure or the second special figure is started. Therefore, it is determined whether or not the special symbol variation time has elapsed (S312). As described above, since the fluctuation time of the first special figure or the second special figure is determined in advance according to the fluctuation pattern, a predetermined timer (fluctuation is started simultaneously with the start of the fluctuation of the first special figure or the second special figure. It is possible to determine whether a predetermined fluctuation time has elapsed by setting the fluctuation time in the time measurement timer. As a result, when the variation time has not yet elapsed (S312: no), the special symbol game process of FIG. 13 and FIG. 14 is finished as it is, and the process returns to the game control process shown in FIG.

  On the other hand, if it is determined that the fluctuation time has passed (S312: yes), a command (design stop command) indicating that the first special figure or the second special figure during the fluctuation display is stopped is displayed. The data is transmitted toward the control board 220 (S314), and the first special figure or the second special figure in the variable display is stopped and displayed with a predetermined stop symbol (S3126 to S3130 in FIG. 15) (S316). . Then, after setting a time (stop display time) for holding the special symbol displayed in a stopped state in a stopped state (S318), it is determined whether or not the set stop display time has passed (S320). As a result, if the stop display time has not elapsed (S320: no), the special symbol game process is terminated as it is, and the process returns to the game control process shown in FIG.

  After returning to the game control process of FIG. 11 with the first special figure and the second special figure being stopped and displayed in this way, when the special symbol game process of FIGS. 13 and 14 is started again, the first special figure is started. And it is determined that the second special figure is not changing (S304: no), and then it is determined that it is during the stop display time for the special symbol during the stop display time (S306: yes). Then, it is determined again whether the stop display time has elapsed (S320). If it is determined that the stop display time has passed while repeating such determination (S320: yes), the special symbol (the first special symbol or the second special symbol) is stopped at the big hit symbol this time. It is determined whether or not it is displayed (whether or not the stop symbol stored in S3128 in FIG. 15 is a big hit symbol) (S322 in FIG. 14). If the special symbol (the first special symbol or the second special symbol) is stopped and displayed as a big hit symbol (S322: yes), the type of the big hit symbol that has been stopped (four types of big hit symbols (AD) )], "Type of special symbol with big hit symbol stopped (either 1st special figure or 2nd special symbol)", "Game state when jackpot symbol is stopped and displayed (probability of jackpot) Is a normal probability or a high probability) ”is stored in a predetermined address of the RAM 203 mounted on the main control board 200 (S324). As will be described in detail later, in the pachinko machine 1 according to the present embodiment, “the type of the jackpot symbol that is stopped and displayed”, “the type of the special symbol that the jackpot symbol is stopped and displayed”, and “the jackpot symbol when the jackpot symbol is stopped and displayed. In accordance with the “game state” and “the number of jackpots in the high probability state”, a high probability flag, an open extension flag, etc. are set (ON or OFF) when the jackpot game is terminated.

  Subsequently, an opening pattern of the big winning opening 31d during the big hit game is set (S326). As described above, in the pachinko machine 1 according to the present embodiment, four types of jackpot games (A to D) are provided in association with the four types of jackpot symbols (A to D), respectively (see FIG. 9). The four types of big hit games (A to D) differ in the opening time of the special winning opening 31d, the prescribed number of balls entered, and the number of times of opening (number of rounds). Therefore, in the process of S326, the opening time, the specified number of balls and the number of rounds are set as the opening pattern of the big winning opening 31d in accordance with the types (A to D) of the big hit symbols that are stopped and displayed.

  When the opening pattern of the big winning opening 31d is set in this way, the big hit flag is set to ON in order to start the big hit game (S328). The big hit flag is a flag indicating that a big hit game is being executed (during the big hit game), and a predetermined address of the RAM 203 mounted on the main control board 200 is assigned as the big hit flag. The CPU 201 of the main control board 200 grasps whether or not the big hit game is being executed according to the set state of the big hit flag. As will be described in detail later, when returning to the game control process of FIG. 11 with the jackpot flag set to ON, the jackpot game process is executed and the jackpot game is started.

  If the other big flags (open extension flag, fluctuation shortening flag, high probability flag) are set to ON when the big hit game is started (set to the big hit flag ON), the ON flag is set. Set to OFF. These flags are set anew when the big hit game ends (turns off the big hit flag). When the flag setting process for starting the big hit game is completed (S328, S330), a command indicating that the big hit game is started (a big hit game start command) is transmitted to the sub control board 220 (S332). The special symbol game process shown in FIGS. 13 and 14 is terminated, and the process returns to the game control process of FIG. When the CPU 221 of the sub control board 220 receives the jackpot game start command, the CPU 221 executes a display effect corresponding to the jackpot game on the display screen of the effect display device 27.

  The above describes the processing when the special symbol (first special symbol or second special symbol) stopped and displayed on the first symbol display device 28 or the second symbol display device 32 is a big hit symbol (S322: yes). However, when the special symbol is removed and is stopped and displayed as a symbol (S322: no), the following processing is performed. First, it is determined whether or not the high probability flag is set to ON (S334). As described above, the high probability flag is a flag indicating that the jackpot probability is set to a high probability, and in this embodiment, when the jackpot symbol is stopped and displayed in a state where the jackpot probability is a normal probability ( In the case of so-called first hit), the big hit probability is set to a high probability until a predetermined number of big hit games are played. If the high probability flag is not set to ON (S334: no), it is then determined whether the release extension flag and the fluctuation reduction flag are set to ON (S336). As will be described in detail later, in the pachinko machine 1 of the present embodiment, when the jackpot game is performed a predetermined number of times with a high probability of jackpot, and the normal probability is returned, the release extension flag is set to ON and the second As the opening time of the start port 17b becomes long (5 seconds) (open extension function is activated), the fluctuation shortening flag is set to ON and the fluctuation time of the special symbol (first special figure, second special figure) Is shortened (variation reduction function is activated). The opening extension function and the fluctuation shortening function are configured to stop (end) the operation when the number of subsequent special symbol fluctuation displays reaches the set number of times. In S336, it is determined whether or not the opening extension function and the fluctuation shortening function are activated based on the setting states of the opening extension flag and the fluctuation shortening flag. Note that the release extension flag and the fluctuation reduction flag are set to different predetermined addresses in the RAM 203 mounted on the main control board 200.

  If the opening extension flag and the fluctuation shortening flag are set to ON in S336, that is, if the opening extension function and the fluctuation shortening function are operating (S336: yes), “1” is set from the opening extension and fluctuation shortening counter. After subtracting (S338), it is determined whether or not the open extension and fluctuation shortening counter has become “0” (S340). The opening extension and fluctuation shortening counter is a counter in which the number of remaining fluctuation display times of the special symbol is set until the operation of the opening extension function and the fluctuation shortening function is stopped (terminated), and the variation display of the special symbol is terminated ( "1" is subtracted every time the special symbol is stopped). If the opening extension and fluctuation shortening counter is not “0” (S340: no), the operation of the opening extension function and the fluctuation shortening function is continued. Therefore, the special symbol game processing is terminated as it is, and FIG. Return to the game control process shown in FIG.

  On the other hand, when the opening extension and variation shortening counter becomes “0”, both the opening extension flag and the variation shortening flag are set to OFF in order to stop the operation of the opening extension function and the variation shortening function (S342). Then, when a game state designation command is transmitted toward the sub control board 220 (S344), the special symbol game process is terminated and the process returns to the game control process of FIG. Here, the gaming state designation command is a command for designating the gaming state determined according to the setting of the high probability flag, the fluctuation shortening flag, the release extension flag, or the like to the sub-control board 220.

  On the other hand, when the high probability flag is set to ON in the determination of S334, that is, when the big hit probability is set to a high probability (S334: yes), in the determination of S336, the open extension flag and the fluctuation reduction When the flag is not set to ON, that is, when the release extension function and the fluctuation reduction function are not activated (S336: no), the special symbol game process is terminated without performing the processes after S338, Returning to the game control process of FIG.

  As shown in FIG. 11, in the game control process, when returning from the special symbol game process, it is determined whether or not the big hit flag is set to ON (S350). As described above, the big hit flag is a flag indicating that the big hit game is being played. Therefore, when the big hit flag is set to ON (S350: yes), the CPU 201 of the main control board 200 starts the big hit game process described below (S400). On the other hand, if the jackpot flag is not set to ON (S350: no), the jackpot game process is omitted and the process returns to the top of the game control process.

C-4. Jackpot game processing:
FIG. 19 is a flowchart showing the big hit game process. In addition, a big hit game (hit game) is performed when 201 of the main control board 200 executes this big hit game process. Therefore, the CPU 201 mounted on the main control board 200 of this embodiment corresponds to the “hit game execution means” of the present invention. Hereinafter, the big hit game process will be described with reference to FIG.

  When starting the big hit game process (S400), the CPU 201 of the main control board 200 first determines whether or not the big winning opening 31d is open (S402). The big winning opening 31d is normally closed (when it is not a big hit game), and therefore, the big winning opening 31d is closed immediately after the start of the big hit game. Accordingly, it is determined that the special winning opening 31d is not open (S402: no), and it is determined whether or not the number of round games (number of rounds) has reached a predetermined number (S404). As described above, during the big hit game, the big winning opening 31d is opened and a predetermined number of round games are repeated. Corresponding to this, when the special winning opening 31d is closed (S402: no), the number of opening (number of rounds) of the special winning opening 31d is a predetermined number (the number of opening set in S326 in FIG. 14). Is determined (S404).

  Naturally, immediately after the big hit game is started, the number of rounds has not reached the predetermined number (S404: no), so it is determined whether or not the closing time of the special winning opening 31d has elapsed (S406). The closing time of the special winning opening 31d is a time during which the special winning opening 31d is in a closed state between rounds. In the present embodiment, the closing time of the special winning opening 31d is set to 1 second. Immediately after the big hit game is started, the big prize opening 31d is in a closed state, so it is naturally determined that the closing time of the big prize opening 31d has passed (S406: yes), and the big prize opening 31d is opened. The game is released and a new round game is started (S408). Then, after a command indicating the start of the round game (round start command) is transmitted to the sub-control board 220 (S410), the big hit game process shown in FIG. 19 is once ended, and the game control process of FIG. Return.

  When the CPU 201 of the main control board 200 returns to the game control process, as shown in FIG. 11, after performing a series of various processes after the prize ball related process (S50), the big hit game process (S400) is started again. . As described above, the time required for the CPU 201 of the main control board 200 to execute the game control process shown in FIG. 11 once is about 4 msec. Accordingly, the big hit game process shown in FIG. 19 is also executed about every 4 msec. Then, when the special game is started and the jackpot game process of FIG. 19 is executed for the first time, as described above, the big winning opening 31d is opened in S408, and the process is ended as it is, but after about 4 msec, 2 When performing the process of the round, it is determined in S402 that the special winning opening 31d is open (S402: yes).

  Subsequently, it is determined whether or not the opening time of the special winning opening 31d has reached a predetermined opening time (opening time set in S326 of FIG. 14) (S412). As described above, in the big hit game, the big winning opening 31d is opened, but is closed when a predetermined opening time elapses or a predetermined number of game balls enter the big winning opening 31d. In response to this, in S412, it is determined whether or not a predetermined opening time has elapsed since the special winning opening 31d was opened. If the opening time has elapsed (S412: yes), after closing the big prize opening 31d (S416), the big hit game process shown in FIG. 19 is exited and the game control process shown in FIG. 11 is resumed. On the other hand, if the predetermined opening time has not elapsed (S412: no), it is determined whether or not the number of game balls that have entered the special winning opening 31d has reached the specified number of balls (S414). When the game ball reaches the specified number of balls (S414: yes), the special winning opening 31d is closed (S416). On the other hand, if the prescribed number of balls has not been reached (S414: no), the predetermined opening time has not yet elapsed since the big winning opening 31d was opened, and the big winning opening 31d was entered. Since the game balls that have been played have not reached the specified number of balls, the game is returned to the game control process of FIG. 11 by leaving the big hit game process shown in FIG.

  While the game control process of FIG. 11 is repeatedly executed, whether a predetermined opening time elapses after the special winning opening 31d is opened (S412: yes), or the predetermined winning entry into the special winning opening 31d A number of game balls enter (S414: yes), and the special winning opening 31d is closed (S416). Thus, one round game is completed. Then, when the big hit game process is executed next, it is determined in S402 that the big winning opening 31d is closed (S402: no), so it is determined whether or not a predetermined number of round games have ended (S404). If all the round games have not ended (S404: no), after confirming that the closing time of the big prize opening has reached a predetermined time (S406: yes), the new prize opening 31d is opened again. A round game is started (S408), and a round start command is transmitted to the sub-control board 220 (S410). On the other hand, if it is determined in S404 that the predetermined number of round games have ended (S404: yes), the big hit flag is changed to OFF to end the big hit game (S418), indicating the end of the big hit game. After transmitting the command (big hit game end command) toward the sub-control board 220 (S420), the big hit end processing is started (S450).

  As described above, in the pachinko machine 1 of this embodiment, various flags (high probability flag, fluctuation shortening flag, release extension flag) are temporarily turned off as the big hit game is started (the big hit flag is turned ON). Set. Then, when the big hit game is ended, by setting various flags again, it is possible to set various game states determined according to the setting status of the various flags. The game state is set in accordance with the “type of jackpot symbol displayed in a stopped state”, “special symbol type in which the jackpot symbol is stopped”, and “game when the jackpot symbol is stopped and displayed” stored in S324 of FIG. Based on the “state” and “the number of jackpots in the high probability state”, the following jackpot end process is performed.

  FIG. 20 is a flowchart showing the big hit end process. When the big hit end process is started, first of all, whether or not the big hit probability is high at the time of the big hit symbol stop display (when the big hit occurs) that triggered the start of this big hit game (high probability) It is determined whether or not the flag is ON (S4500). If the jackpot probability is not high, that is, if the jackpot probability is a normal probability (S4500: no), “4” is set in the limit counter (S4502). As described above, in the pachinko machine 1 of the present embodiment, when the big hit symbol is stopped and displayed in a normal probability state (so-called first hit), the predetermined number of times (including the first hit in this embodiment) is included. The big hit probability is set to a high probability until five (5) big hit games are played, and when a predetermined number of big hit games are played, the normal probability is restored. The limit counter is a counter in which the number of remaining jackpot games until the jackpot probability returns to the normal probability is set, and since the first jackpot game based on the first hit has already ended, the remaining number of times “4 Is set in the limit counter, a high probability flag indicating that the jackpot probability is high is set to ON (S4504). Note that the high probability flag set to ON in this way is maintained in the ON state until the next big hit (see S330 in FIG. 14). Further, since the CPU 201 of the main control board 200 sets the high probability flag to change the jackpot probability, the CPU 201 mounted on the main control board 200 of the present embodiment is the “probability changing means” of the present invention. It corresponds to.

  On the other hand, if the big hit probability is high when the big hit occurs (S4500: yes), since the second and subsequent big hit games have been performed, “1” is subtracted from the limit counter (S4506). It is then determined whether the limit counter has reached “0” (S4508). As a result, if the limit counter is not “0” (S4508: no), since the big hit probability remains high, the high probability flag is set to ON (S4504). When the high probability flag is turned on in this way, a process of setting the release extension flag and the fluctuation shortening flag (open extension flag and fluctuation reduction flag setting process) is started (S4510). Since the CPU 201 of the main control board 200 executes the opening extension flag and the fluctuation reduction flag setting process, the opening time of the second starting port 17b (opening / closing type starting port) is set. The CPU 201 mounted on the main control board 200 corresponds to the “open time setting means” of the present invention.

  FIG. 21 is a flowchart showing the opening extension flag and fluctuation reduction flag setting process. As shown in the drawing, in the release extension flag and fluctuation reduction flag setting process, first, it is determined whether or not the big hit symbol that triggered the start of the current big hit game has been stopped and displayed in the first special figure (S4512). . Then, when the big hit symbol is stopped and displayed in the first special symbol (S4512: yes), the open extension flag and the fluctuation reduction are performed regardless of which of the big hit symbols (A to D) is stopped and displayed. The flag is set to ON (S4514), and the opening extension flag and fluctuation reduction flag setting process is terminated. Then, the process returns to the big hit end process in FIG. As described above, when the opening extension flag is set to ON, the opening time of the second start port 17b is set to a long time (5 seconds), and it is easy to enter the second start port 17b. Then, the game mainly based on the first special figure is switched to the game mainly based on the second special figure. Note that the release extension flag and the fluctuation reduction flag set to ON in S4514 are maintained ON until the next big hit (see S330 in FIG. 14), similarly to the high probability flag (4504 in FIG. 20). ).

  On the other hand, when the big hit symbol is stopped and displayed in the second special figure (S4512: no), the stopped big hit symbol is one of the four types of big hit symbols (A to D). It is determined whether or not the jackpot symbol C or jackpot symbol D (that is, whether the jackpot game is a "game per low profit" or "game per high profit") (S4516). As described above, in the pachinko machine 1 according to the present embodiment, the four types of jackpot symbols (A to D) are associated with the four types of jackpot games (A to D), respectively (see FIG. 9). When the symbol A or the jackpot symbol B is stopped and displayed, the jackpot game ("15R multiplayer per hit" or "5R multiplayer per hit") in which the player can acquire many prize balls, that is, the game per high profit When the big hit symbol C or the big hit symbol D is stopped and displayed, the big hit game ("5R small ball hit" or "2R small ball hit") is difficult for the player to win a prize ball. That is, a game per low profit is executed. When the jackpot symbol that has been stopped is jackpot symbol A or jackpot symbol B (that is, the jackpot game is "game per high profit") (S4516: no), the release extension flag and the variable reduction flag are turned on. (S4514), the release extension flag and fluctuation reduction flag setting process is terminated, and the process returns to the big hit end process of FIG.

  On the other hand, when the jackpot symbol stopped and displayed in the second special symbol is the jackpot symbol C or the jackpot symbol D (S4516: yes), the release extension flag and the fluctuation reduction flag are not set to ON, and the release is performed. The extension flag and fluctuation shortening flag setting process is terminated, and the process returns to the big hit end process in FIG. As described above, when the open extension flag is not set to ON, the opening time of the second start port 17b is set to a short time (0.5 seconds), and the fixed first type is set to be more fixed than the second start port 17b. Since there is a high possibility of entering the 1 start opening 17a, a game mainly composed of the first special figure is performed.

  As shown in FIG. 20, when the CPU 201 of the main control board 200 returns from the opening extension flag and fluctuation reduction flag setting process, it transmits a gaming state designation command to the sub control board 220 (S4520), and when the big hit ends The process ends. And it returns to the big hit game processing of FIG.

  In the above, the processing when the so-called first hit (S4500: no) or the limit counter is not “0” (S4508: no) and the high probability flag is set to ON (S4504) is described. did. On the other hand, when the limit counter becomes “0” (S4508: yes), it means that a predetermined number of big hit games have already been performed, so that the high probability flag is not set to ON and the extension is extended. After setting “100” in the fluctuation shortening counter (S4530), the release extension flag and the fluctuation shortening flag are set to ON (S4532). As described above, the value of the open extension / variation shortening counter represents the remaining number of times of display of the special symbol until the operation of the open extension function and the variation shortening function is stopped. “1” is subtracted from (S338 in FIG. 14). In the present embodiment, when the jackpot game is performed a predetermined number of times with a high probability of jackpot and returns to the normal probability, regardless of the type of jackpot game played at the end (predetermined number of times), the extended extension function and The variation shortening function is activated and the variation display of the special symbol is continued until the set number of times (100 times) is performed. Accordingly, after setting the opening extension and fluctuation reduction counter to “100” and then setting the release extension flag and the fluctuation reduction flag to ON, the big hit end processing is terminated and the big hit game processing of FIG. 19 is resumed. Further, in the big hit game process of FIG. 19, when returning from the big hit end process, the process ends as it is. Then, when returning to the game control process shown in FIG. 11, the process returns to the beginning, and a series of processes after the above-mentioned prize ball related process (S50) are repeated.

  As described above, in this embodiment, when the high probability flag is set to ON (S4504 in FIG. 20) and the big hit probability is high until the next big hit occurrence, the release extension flag and the fluctuation reduction flag Is set to ON (S4514 in FIG. 21), the operation of the open extension function and the fluctuation reduction function is continued until the next big hit. However, even when the opening extension flag and the fluctuation shortening flag are set to ON in S4514, a configuration using the opening extension and fluctuation shortening counter may be used. That is, when the high probability flag is set to ON in S4504, “10000” is set to the high probability counter indicating the remaining number of fluctuation display times of the special symbol until the high probability flag is set to OFF, and is opened in S4514. When the extension flag and the fluctuation shortening flag are set to ON, “10000” is set to the open extension and fluctuation shortening counter, and “1” is subtracted from each counter every time the special symbol fluctuation display ends. Also good. If the big hit probability is high, it will be a big hit with a probability of about 8.8 (see FIG. 17B), so if “10000” is set in each counter, the next time will be substantially the next. Until the big hit occurs, the big hit probability is set to a high probability, and the operation of the open extension function and the fluctuation reduction function is continued.

  The CPU 201 mounted on the main control board 200 advances the game in the pachinko machine 1 by repeatedly performing the game control process as described above. Here, as described above, in the pachinko machine 1 according to the present embodiment, the game (big hit lottery) in the first special figure is executed based on the ball entering the fixed first start port 17a, and the open / close type Based on the ball entering the second starting port 17b, the game in the second special figure is executed. In addition, the probability that each jackpot symbol (A to D) is stopped and displayed when the jackpot lottery is won is different between the first special chart and the second special chart (see FIG. 18), and the jackpot game is A jackpot game (A to D) corresponding to the jackpot symbol displayed in a stopped state is executed. Further, when the big hit game is ended, an open extension flag is set in accordance with “a special symbol type in which the big hit symbol is stopped” or “a special type in which the big hit symbol is stopped”. As a result, in the pachinko machine 1 according to the present embodiment, the jackpot game of a predetermined number of times (5 including the first hit) performed while the jackpot probability is high is a jackpot game in which it is difficult to obtain a prize ball ( It is possible to suppress the occurrence of only low profit per game. Hereinafter, this point will be described in detail.

  FIG. 22 is a time exemplifying a game state (such as an operating state of an extended extension function based on the type of jackpot symbol) after the first hit occurs until a predetermined number (5 times) of jackpot game including the first hit is consumed. It is a chart. As described above, in the pachinko machine 1 according to the present embodiment, the fixed first start port 17a and the openable second start port 17b are provided, and the ball enters the first start port 17a. A game of the first special figure (lottery lottery) is performed, and a game of the second special figure is performed based on the ball entering the second starting port 17b.

  First, in the gaming state where the opening extension function is not activated, as described above, the opening extension flag is set to OFF, and even if the opening condition of the openable second start port 17b is satisfied, the opening time Is a short time (0.5 seconds). For this reason, the possibility that a game ball enters the first start port 17a that can always enter the ball is higher than that of the second start port 17b. Therefore, the game in the first special figure (game mainly based on the first special figure) is performed. Normally, when the first hit occurs, the open extension function is not activated with a normal probability. However, after a predetermined number of (5) jackpot games have been played and the jackpot probability has returned from the high probability to the normal probability, the period until the special symbol change display is performed the set number of times (100) is the normal probability. In addition, the open extension function is activated. In other words, even if the open extension function is in operation, if a big hit occurs with a normal probability of big hit, the first hit is obtained.

  And if a big hit (first hit) occurs while repeating the game (hit big lottery) mainly on the first special figure with the big hit probability being a normal probability, one of the four types of big hit symbols (A to D) Is stopped. At this time, the determination of the jackpot symbol to be stopped is performed with reference to the jackpot symbol determination table for the first special symbol in FIG. 18A, and as described above, when the big bonus symbol occurs in the first special symbol Is set with a high possibility that the jackpot symbol A or the jackpot symbol B is determined as the jackpot symbol. In the example shown in FIG. 22, since the big hit symbol A is stopped and displayed at the first hit, the big hit game A corresponding to the big hit symbol A (15R multiplayer hit) is executed as the first big hit game, and the player Can win a lot of prize balls.

  Thus, when the first jackpot game based on the jackpot occurrence in the first special figure is completed, the jackpot probability is set to a high probability (the high probability flag is set to ON), and the release extension flag and the fluctuation shortening flag are set. Set to ON. The fluctuation time of the special symbol (first special figure, second special figure) is shortened by turning on the fluctuation shortening flag, and the opening time of the second start port 17b is long by turning on the opening extension flag. It is set to time (5 seconds), and it becomes easy to enter the second start port 17b. Further, in the pachinko machine 1 according to the present embodiment, the game of the second special figure is started with priority over the game of the first special figure, so that the game is mainly based on the second special figure. In the gaming state in which the release extension flag and the fluctuation shortening flag are set to ON, the number of balls entering the second start port 17b per unit time increases and the fluctuation time of the second special figure is also shortened. The number of jackpot lotteries performed per unit time will increase significantly. Accordingly, the next big hit will occur in a short time, coupled with the fact that the big hit probability is set to a high probability.

  As mentioned above, if you play a game with the second special chart as the main feature (big hit lottery) with a high probability of big hit, you can easily (in a short time) generate big hits. Any one of (A to D) is stopped and displayed. The determination of the jackpot symbol to be stopped and displayed as the second special symbol is performed with reference to the big bonus symbol determination table for the second special symbol in FIG. 18B, and as described above, the big bonus symbol is generated in the second special symbol. In such a case, the possibility that the jackpot symbol C or the jackpot symbol D is determined as the jackpot symbol is set high. When the jackpot symbol C is stopped and displayed, the jackpot game C corresponding to the jackpot symbol C (5R out-of-ball small hit) is executed as the second jackpot game. However, in this jackpot game C, the player can hardly obtain a prize ball.

  When a big hit occurs in the second special figure and the big hit game C corresponding to the stopped big hit symbol C ends, the big hit probability is set to a high probability, but the release extension flag and the fluctuation reduction flag are set to ON. Without being done, it is kept OFF. Therefore, the variation time of the special symbol is longer than that when the variation shortening flag is ON, and the opening time of the second start port 17b is short (0.5 seconds), and the second start port 17b. Entering the ball becomes difficult. However, if the second special figure is retained at the start of the variation of the special symbol after the big hit game ends, the big hit lottery based on the second special figure is preferentially performed. Then, when all the second special figure reservations (maximum of four) are digested, the game is switched to a game mainly composed of the first special figure. In addition, since it is difficult to enter the first start port 17a as compared to the second start port 17b that is opened for a long time (5 seconds), in a game mainly composed of the first special figure, per unit time. The number of jackpot lotteries to be performed is reduced compared to when the open extension function is activated. Therefore, compared to when the opening extension function and the fluctuation shortening function are activated, it takes a long time until the next big hit occurs, but since the big hit probability is high, the normal extension and the open extension function are activated. Big hits occur in a short period of time compared to a non-existent state (so-called normal state).

  In this way, when the game is switched to the game with the first special figure as the main, when the big hit is made, the big hit symbol A or the big hit symbol B (the big hit symbol corresponding to the high profit per game) may be determined again as the big hit symbol Becomes higher. When the jackpot symbol B is stopped and displayed, the jackpot game B corresponding to the jackpot symbol B is executed as the third jackpot game and is smaller than the jackpot game A. It is possible to win more prize balls than games per profit.

  Also, when the first special figure is a big hit and the third big hit game ends, the release extension flag and the fluctuation shortening flag are set to ON again, the special symbol fluctuation time is shortened, and the second start The opening time of the mouth 17b is long (5 seconds). As a result, the frequency of entering the second starting port 17b increases, and the game is switched to a game mainly composed of the second special figure. As described above, when a big hit occurs in the second special figure, the possibility of determining the big hit symbol C or the big hit symbol D is set as the big hit symbol. However, there is a possibility that the jackpot symbol A or the jackpot symbol B is determined as a jackpot symbol (see FIG. 18B), and in the example shown in FIG. Is displayed. In this case, the jackpot game A (15R hitting multiple hits) corresponding to the jackpot symbol A is executed as the fourth jackpot game. By executing the jackpot game A, the player can acquire a large amount of prize balls.

  When jackpot game A is played based on the fact that jackpot symbol A is stopped and displayed in the second special chart, the jackpot probability is set to a high probability at the end of the game (the high probability flag is set to ON). ) And the open extension flag and the fluctuation reduction flag are set to ON. Thus, the opening time of the second start port 17b becomes a long time (5 seconds), and the game mainly having the second special figure is started again. As a result, the winning frequency of the big hit lottery is high and the big hit probability is high, so that the next (fifth) hit will occur in a short time. In this way, when the jackpot symbol A or the jackpot symbol B (the jackpot symbol corresponding to the high profit per game) is stopped and displayed in the second special chart, after the corresponding jackpot game is finished, the opening extension function and the fluctuation are again performed. Since the shortening function operates, a lot of big hit lotteries can be executed in a short time, and as a result, a large number of prize balls can be acquired in a short time. Then, after the big hit game A is over, a game (hit lottery lottery) mainly consisting of the second special figure is performed, and if the big special symbol D is stopped and displayed as a big hit in the second special figure, it corresponds to the big hit symbol D The big hit game D (2R small ball hit) is executed as the fifth big hit game. In this jackpot game D, the player cannot substantially obtain a prize ball.

  In this way, when the fifth big hit game based on the big hit in the second special figure is completed, it means that the predetermined number of big hit games have been digested (after the predetermined number of big hit games have ended), so the big hit probability is set to the normal probability. (High probability flag is set to OFF). In addition, after the end of the predetermined number of jackpot games, the type of the jackpot game (whether the stopped jackpot symbol is one of the jackpot symbols A to D) or the type of the special symbol in which the jackpot symbol is stopped ( Regardless of whether it is a big hit in the first special figure or a big hit in the second special figure), the open extension flag and the fluctuation reduction flag are set to ON. As a result, a game mainly composed of the second special figure is performed, but when the special symbol variation display is performed the set number of times (100 times), the release extension flag and the variation shortening flag are turned OFF, and the second special figure is displayed. As soon as there is no longer any hold, the game will be switched to a game mainly composed of the first special figure. Thereafter, when the first hit occurs again, the big hit probability is set to a high probability until the predetermined number (5 times) of the big hit game is consumed. In addition, when a big hit is made during the operation of the extension extension function for the set number of times (100 times) set after the end of the predetermined number of times (fifth) big hit game (so-called pullback), It is assumed that the hit has occurred, and the big hit probability is high until the predetermined number of big hit games is completed.

  As described above, in the pachinko machine 1 according to the present embodiment, the jackpot game C or the jackpot game D (game per low profit) is based on the fact that the jackpot symbol C or the jackpot symbol D is stopped and displayed in the second special chart. When the big hit game is finished, the opening extension flag is not set to ON (the opening extension function is not activated), making it difficult to enter the openable second start port 17b. Therefore, the game is switched to a game (big hit lottery) mainly based on the first special figure. As a result, unlike conventional pachinko machines that increase the probability of jackpot and maintain the operation of the extended extension function until the predetermined number of jackpot games is over, all or most of the predetermined number of jackpot games are games with low profits. In addition, it is possible to prevent the high probability state from being finished in a short time (predetermined number of big hits in a short time). On the other hand, when the big hit game A or the big hit game B (high profit per game) is performed based on the fact that the big hit symbol A or the big hit symbol B is stopped and displayed in the second special figure, the extension extension function is performed after the big hit game is finished. By operating the, it is possible to maintain the euphoria that a large amount of prize balls can be obtained in a short time.

  In addition, unless the jackpot game based on the jackpot in the first special figure is a high-profit game (a lot of balls), the game is mainly switched from the second special figure to the game mainly based on the first special figure. Even so, there is a possibility that games per low profit will continue (the possibility is not zero), but the probability that the big hit game based on the big hit in the first special figure will be a game per high profit (big hit symbol as a big hit symbol) By making the probability of A or jackpot symbol B being determined) higher than the probability that the jackpot game based on the jackpot in the second special chart will be a game per high profit, the game per low profit (small hitting ball) The possibility of being repeated can be reduced.

  Furthermore, in the pachinko machine 1 of the present embodiment, when a big hit occurs in the first special figure, the big hit symbol A or the big hit symbol B is determined as the big hit symbol rather than the probability that the big hit symbol C or the big hit symbol D is determined. The game with a high profit (hit many balls) is executed by the stop display of the jackpot symbol A or the jackpot symbol B. For this reason, after a low profit per game based on a big hit in the second special figure (a small hit in the starting ball) is performed, a game mainly having the second special figure is switched to a game mainly having the first special figure. And the possibility that the next big hit will occur in a short time will be low (the number of big hit lotteries performed per unit time will be reduced), and there will be a demerit that the holding ball will decrease, but the next big hit game will be The possibility of becoming a game per high profit (per lot of balls) increases, and it is possible to suppress a series of games per low profit (small per ball). As a result, in the pachinko machine 1 of this embodiment in which the big hit probability is set to a high probability until the predetermined number of times (five times) of big hit games are played by the first hit, the predetermined number of big hit games are games per low profit ( As a result, it is possible to prevent the player from having only a small number of hit balls) and to increase the possibility that the player will win a prize ball.

D. Modified example:
Below, the modification of the pachinko machine 1 of a present Example is demonstrated. In the description of the modification, the same components as those of the above-described embodiment are denoted by the same reference numerals as those of the above-described embodiment, and the detailed description thereof is omitted.

D-1. First modification:
In the embodiment described above, in the jackpot symbol determination table for the second special symbol (see FIG. 18B), the jackpot symbol A or the jackpot symbol B (high The probability that the jackpot symbol C or the jackpot symbol D (the jackpot symbol corresponding to the low profit game) is determined is set higher than the probability that the jackpot symbol corresponding to the game per profit) is determined. However, the present invention is not limited to this, and the probability that the big hit symbol A or the big hit symbol B is determined as the big hit symbol at the time of the big hit in the second special figure is the big hit symbol C or the big hit symbol D. You may set higher than the probability determined.

  As a specific example, FIG. 23 is an explanatory view illustrating a jackpot symbol determination table for the second special figure in the first modification. As shown in the figure, the ratio of the jackpot symbol A (30%) and the jackpot symbol B (30%) among the symbol determination random numbers “0 to 99” is the jackpot symbol C (20%) and the jackpot symbol D ( 20%). Therefore, even if a big hit occurs in the second special drawing, the big hit symbol A or the big hit symbol B is more easily stopped and displayed than the big hit symbol C or the big hit symbol D, and the player can win a lot of winning balls ( There is a high possibility that “15R multiple hits” and “5R multiple hits”) will be executed. That is, the possibility of becoming a game per high profit is higher than the possibility of becoming a game per low profit. However, when compared with the jackpot symbol determination table for the first special symbol of FIG. 18A, the ratio of the jackpot symbol A and the jackpot symbol B in the symbol determination random numbers of “0 to 99” is the second special symbol. The jackpot symbol determination table (80%) for the first special symbol is higher than the jackpot symbol determination table for the first special symbol (60%). For this reason, when a big hit occurs in the first special figure, there is a higher possibility that a game per high profit (multiple hits) will be executed than when a big hit occurs in the second special figure.

  Thus, in the jackpot symbol determination table for the second special symbol, the jackpot symbol A or the jackpot symbol B is set more likely to be determined as a stop symbol than the jackpot symbol C or the jackpot symbol D. However, the ratio of the jackpot symbol A and the jackpot symbol B is preferably higher in the jackpot symbol determination table for the first special symbol than in the jackpot symbol determination table for the second special symbol. In this way, when the low profit per game based on the big hit in the second special figure (the small hit of the starting ball) is finished, the second flag is set to OFF (without operating the opening extension function). By switching from a game with a special figure as the main game to a game with the first special figure as the main, the possibility that the next big hit game will be a game with high profits (a lot of balls), with the second special figure as the main The game can be increased compared to the case of continuing the game. As a result, it is possible to increase the proportion of games with high profits (per-ball multiple hits) in a predetermined number of big hit games.

D-2. Second modification:
In the embodiment described above, when the jackpot game based on the jackpot in the first special figure is finished, regardless of which of the four kinds of jackpot symbols (A to D) is stopped and displayed, the open extension flag and the fluctuation The shortening flag was set to ON. However, when the jackpot symbol that is stopped and displayed is the jackpot symbol C or the jackpot symbol D, the release extension flag and the fluctuation reduction flag may not be set to ON.

  FIG. 24 is a flowchart showing the opening extension flag and variation reduction flag setting process of the second modification. As shown in the drawing, in the opening extension flag and variation shortening flag setting process of the second modified example, when the big special symbol is stopped and displayed in the first special figure (S4512: yes), subsequently, Determine whether the jackpot symbol that has been stopped is a jackpot symbol A or jackpot symbol B (a jackpot symbol corresponding to a high profit game), or a jackpot symbol C or a jackpot symbol D (a jackpot symbol corresponding to a low profit game) (S4513). If the jackpot symbol that has been stopped is neither the jackpot symbol C nor the jackpot symbol D, but the jackpot symbol A or the jackpot symbol B (S4513: no), the release extension flag and the fluctuation shortening flag Is set to ON (S4514), the opening extension flag and fluctuation shortening flag setting process is terminated, and the process returns to the big hit end process in FIG.

  On the other hand, if the jackpot symbol that is stopped and displayed is either the jackpot symbol C or the jackpot symbol D (S4513: yes), the release extension flag and the variation flag are not set without setting the release extension flag and the variation shortening flag to ON. The abbreviated flag setting process is terminated, and the process returns to the big hit end process of FIG. As a result, when the big bonus symbol C or big bonus symbol D is stopped and displayed in the first special figure (a game per low profit is performed), the game is mainly switched to the second special figure. The game based on the first special figure will be continued without changing.

  Even if a big hit occurs in the first special figure, the big hit symbol C or the big hit symbol D (the big hit symbol corresponding to the low profit per game) may be stopped and displayed. Small hit) is executed. At the end of the game, if the release extension flag is set to ON (the release extension function is activated) and the game is switched to the second special figure, the big hit symbol C or the big hit symbol D is again displayed when the big hit occurs. There is a possibility that the display of the stop will be higher than the case where the game mainly composed of the first special figure is continued, and the game per low profit (the small number of balls) may be continuously executed. Therefore, if either of the big hit symbol C and the big hit symbol D corresponding to the low profit per game (small hitting ball) is stopped and displayed in the first special figure, after the big hit game (low profit per game) ends. If the game with the first special figure as the main game is continued without setting the release extension flag to ON, it will be a big hit when the next big hit occurs, compared with the case where the game is switched to the second special figure as the main game. The possibility that the symbol A or the jackpot symbol B (the jackpot symbol corresponding to the high profit game) is stopped and displayed can be increased. As a result, the possibility that a game per low profit (a small hit per ball) will continue can be reduced, and as a result, the possibility that the predetermined number of big hit games will be only low profit per game can be further reduced. As described above, when the predetermined number of times (fifth) big hit game is finished, the big hit probability is a normal probability, and the big hit symbol that triggered the start of the predetermined number of big hit games is the big hit symbol A ~. In any case of D, the open extension flag and the fluctuation shortening flag are set to ON.

  The embodiments of the present invention have been described above. However, the present invention is not limited to these embodiments, and the present invention is not limited to the wording of each claim without departing from the scope described in each claim. Can be easily replaced by these, and improvements based on knowledge that a person skilled in the art normally has can be added as appropriate.

  For example, in the above-described embodiment, when a big hit occurs in the first special symbol, one of the four types of big hit symbols (A to D) is stopped and displayed (a big hit symbol for the first special symbol) In the decision table, symbol decision random numbers were set for all four types of jackpot symbols (A to D)). However, when a big hit occurs in the first special symbol, only the big hit symbol A or the big hit symbol B (the big hit symbol corresponding to the high profit per game) is stopped and displayed (in the big hit symbol determination table for the first special symbol) The symbol determination random number may be set only for symbols A and B). In this way, after the low profit per game based on the big hit in the second special figure (the small hits for the starting ball) is finished, when the game is switched to the game mainly based on the first special figure, Since the symbol A or the big hit symbol B is always stopped and displayed, it is possible to avoid the game with low profit per game (small hitting ball).

  Further, in the above-described embodiment, the opening time of the large winning opening 31d at the small hitting ball is set to “0.1 second”, but compared with the high hitting ball (opening time “30 seconds”). If the game ball is difficult to enter (the number of award balls that can be acquired is small), the opening mode of the large winning opening 31d for the small number of balls is not limited to this. For example, the opening time of the special winning opening 31d for a small hitting ball may be “10 seconds”, or the opening time may be “30 seconds”, but the opening and closing may be repeated during that time. Further, the number of times of opening (number of rounds) may be reduced. Of course, the special winning opening 31d may not be opened (the special winning opening 31d is opened in a manner in which a game ball cannot enter).

  In the above-described embodiment, the types of jackpot symbols that are stopped and displayed are the same in the first special figure and the second special figure, but even if they are completely different, only a part of them overlaps. It may be. For example, when the first special symbol is a big hit, the big hit symbols to be stopped are displayed as the big hit symbol 1 (10R: per high profit), the big hit symbol 2 (5R: per high profit), the big hit symbol 3 (2R: When the bonus is determined in the second special chart, the jackpot symbol 1 (10R: per high profit), jackpot symbol 4 (15R: It is also possible to determine any one of the big hit symbol 5 (4R: per low profit) and the big hit symbol 6 (2R: per low profit).

  The present invention can be used for a ball game machine used in a game hall.
