Description

  The present invention relates to a pachinko machine installed in a pachinko parlor.

Currently, various types of pachinko machines are offered, and as one of them, a winning lottery using random numbers is performed when a game ball wins a winning prize opening, and it is determined whether or not to win For example, it is known that a winning lottery result is displayed after a symbol variation display is performed on a symbol display device such as a 7-segment display device or a liquid crystal display. If the player wins the winning lottery, the player can acquire a large amount of game balls. Therefore, making the player interested in the winning lottery result is an important factor for enhancing the interest of the player in the game. For this reason, recently, there is a tendency to provide a pachinko machine that has interest in the results of the winning lottery by displaying various effect images during the variation display of the symbols. As an example of the effect image, for example, the variation time of one symbol is divided into four steps, and one of a plurality of types of effect images is selected at each step, and an effect image having a different aspect at each step is displayed. There is something to be done. As described above, when the aspect of the effect image is changed with the lapse of the variation time, the player's feeling of tension can be increased a plurality of times even in one variation display, and tiredness to the game can be prevented.

  By the way, in a pachinko machine that displays an effect image divided into a plurality of steps as described above, the type of effect image at each step is generally selected by lottery with a probability corresponding to the result of the lottery. However, if the effect image of each step is uniformly selected with a probability according to the result of the winning lottery, for example, if the effect image that is easy to be selected when winning is won, it is hardly selected. A bias occurs in the type of effect image displayed on the screen. For this reason, if the game lasts for a long time, the result of the winning lottery can be detected in advance based on the type of effect image displayed at each step before the display of the change is completed, and the player is interested in the display of the change. Was lost on the way. In this case, it is impossible to prevent the player from getting bored with the game despite the use of a unique method of displaying the effect image divided into a plurality of steps. It was an issue in developing the machine.

  For this reason, when selecting the type of effect image at each step, a plurality of selection probabilities are set for each case of winning or losing so that the type of effect image displayed at each step is not biased. It is possible to keep it. In this method, the selection probability of the effect image at each step is selected according to the result of the winning lottery, and the type of effect image is determined based on the selected probability. As a result, even in the same effect image, it is possible to prevent the selection rate from being biased, and even in the same effect image, the selection rate can be changed depending on whether it is a win or a loss. It is possible to give expectation to the result of the winning lottery while preventing the bias.

  However, if the method as described above is used, the lottery table used for selecting the effect image at each step will increase as compared with the conventional method. Therefore, the data amount related to the lottery table is enormous as compared with the conventional method. This leads to an increase in the development period of the pachinko machine and leads to an increase in the manufacturing cost of the pachinko machine.

  The present invention has been made in consideration of the above-mentioned problems, and when the effect image is displayed over a plurality of steps, the result of the lottery is prevented from being perceived, and the result is expected to be produced, and the manufacturing cost is increased. It is an object of the present invention to provide a pachinko machine that can prevent a rise in the height.

  In order to achieve the above object, the pachinko machine of the present invention performs a winning lottery in the process of determining the winning or losing, displays the winning lottery result by displaying the variation of the symbol, The variation time is divided into a plurality of steps, and each step selects and displays any one of a plurality of types of effect images having different aspects by effect image selection lottery, and the steps differ in each other step. In a pachinko machine that displays effect images, the random number value extracted in the effect image selection lottery is used to determine which of the plurality of types of effect images is assigned, and is provided for each step. A plurality of first effect lottery tables and random image values extracted in the effect image selection lottery are assigned to the plurality of types of effect images. The number of random numbers is set so that the selection rate between the same effect images in each step is different from that in the first effect lottery table, and is used for each step. A plurality of second effect lottery tables, and step selection lottery means for selecting the step of performing the effect image selection lottery using the first effect lottery table when the winning is made by the step selection lottery; In the case of winning, the step selected in the step selection lottery causes the effect image selection lottery to be performed using the first effect lottery table, and other steps are performed using the second effect lottery table. When the effect image selection lottery is performed and the game is lost, the effect image selection is performed using the second effect lottery table in all steps. A lottery control means for causing the drawing, in which the effect image selected by the effect image selection lottery and a effect image display control means for displaying at each step.

  According to the first aspect of the present invention, since the probability is not uniformly changed in all steps, it is possible to prevent the type of effect image displayed in each step from being biased, and the effect image is provided over a plurality of steps. It is possible to prevent the result of the lottery from being perceived when is displayed. In addition, since the selection probability of the effect image is changed in any step when winning in the win, it is possible to give a sense of expectation to the winning lottery result. Furthermore, the number of lottery tables used for selecting the effect images can be made as usual, and an increase in manufacturing cost can be prevented.

  As shown in FIG. 1, the pachinko machine 10 includes a game board 11. A game area 11a is formed on the surface of the game board 11, and the launched game ball flows down the game area 11a. The game area 11a is provided with a first start winning opening (hereinafter referred to as “first starting opening”) 12, a second starting winning opening (hereinafter referred to as “second starting opening”) 13, and a through chucker 14. Yes. When a game ball wins a prize in the first start port 12 or the second start port 13, a predetermined number of game balls determined in advance are paid out as a prize ball. The first start port 12 and the second start port 13 are arranged one above the other, and the second start port 13 is disposed below the first start port 12. A pair of opening / closing members 13a whose base ends are pivotally supported by shafts extending in the front-rear direction are attached to the second start port 13. Normally, the opening / closing member 13a is located at a closed position where the tip ends approach each other, and when the open lottery executed when the game ball passes through the through chucker 14, the opening / closing member 13a rotates to the open position where the tip ends are separated. To do. When the opening / closing member 13a is rotated to the open position, the game ball is guided into the second starting port 13 by the inner surface thereof, so that the game to the second starting port 13 is performed more than when the opening / closing member 13a is positioned at the closed position. The winning rate of the ball increases. The opening time of the movable piece is set to 0.5 seconds per opening. When the opening / closing member 13a is located at the closed position, the gap between the opening / closing members 13a is covered by the first starting port 12, so that the second starting port 13 is played only when the opening / closing member 13a is rotated to the opened position. You can win a ball. Note that “winning” indicates that it is detected that a game ball has entered the winning opening. Accordingly, the through chucker 14 does not receive a prize and does not pay out the prize ball because only the game ball passes through.

  When a game ball wins the first or second starter 12 or 13, a winning lottery for determining a winning or losing is performed. If you win the game, you will move to the 15-round winning mode. The attacker 15 is released once in each round of the hit mode. A large winning opening (not shown) is provided behind the attacker 15. When the attacker 15 is opened, a game ball that passes over the attacker 15 when the attacker 15 is closed is guided to the winning prize opening on the inner surface of the attacker 15. Thereby, a large number of prize balls can be obtained. Then, when 10 game balls are won in the big winning opening or 30 seconds have elapsed from the start of the round, the attacker 15 is closed and one round is completed.

  A center accessory 17 is provided in a substantially central portion of the game area 11a. A liquid crystal display 18 is incorporated in the center accessory 17. On the liquid crystal display 18, symbols arranged side by side in three rows are displayed. When a game ball wins the first or second starting port 12 or 13 during a game in the normal mode, the symbol variation display is started and the symbol scrolls from top to bottom. The effect image is also displayed during the variation display of the symbols. The variably displayed symbols are sequentially stopped one by one (in order of left → right → middle), and when all symbols are stopped, the same symbols are collected, and the other combinations are lost. Note that when the same symbol is stopped on the left and right and the central symbol is in a variably displayed state, if the same symbol as the left and right symbols stops at the center, this state is referred to as reach. An effect image is also displayed from the liquid crystal display 18 during the display of the variation of the symbol. The variation time of the symbol is divided into four steps, and an effect image selected from a plurality of types at each step is displayed, and an effect image having a different aspect at each step is displayed.

  At the lower part of the pachinko machine 10, there are provided a launch handle 19 for launching a game ball to the game area 11a and a tray 20 for storing the paid-out prize ball. When the firing handle 19 is turned, a game ball is launched on the surface of the game board 11, and the launched game ball flows down the game area 11a. An effect button 21 is provided above the firing handle 19. The operation of the effect button 21 is validated when a message prompting the operation is displayed by the effect image. When the effect button 21 is pressed, the aspect of the effect image changes.

  As shown in FIG. 2, the operation of the pachinko machine 10 is controlled by the main board 30. The main board 30 includes a main CPU 31. The main CPU 31 reads out programs and data stored in the ROM area of the main memory 32, and executes payout of prize balls, execution of winning lotteries, and games in each mode. The RAM area of the main memory 32 is used for temporary storage of data and flags related to game execution.

  The first start sensor 33 detects a game ball that has entered the first start port 12, and the second start sensor 34 detects a game ball that has entered the second start port 13. In response to the game ball detection signal from the first start sensor 33 or the second start sensor 34, the main CPU 31 drives a prize ball payout device (not shown) to execute a prize ball payout. The main CPU 31 operates the lottery unit 35 in response to the detection signal.

  The winning lottery unit 35 performs a winning lottery using an electronic random number. In the winning lottery, a random number randomly extracted at the time of the lottery is compared with a winning determination table, and it is determined whether the extracted random number is a random number to which a winning or a lost is assigned. .

  The variation pattern lottery unit 36 is operated after the winning lottery is performed. The variation pattern lottery unit 36 performs a variation pattern lottery using an electronic random number to determine a variation pattern of the symbol. The variation pattern lottery is performed by using a variation pattern table for winning when winning in the winning lottery and using a variation pattern table for losing when winning in the winning lottery. In each of the winning variation pattern table and the loss variation pattern table, one of a plurality of types of variation patterns is assigned to all random numbers extracted in the variation pattern lottery. Then, the variation pattern is determined depending on which variation pattern is assigned to the random number value extracted in the variation pattern lottery. The variation patterns assigned in the hit variation pattern table are composed of four types: normal per, A per super reach, B per super reach, and C per super reach. Further, the variation patterns assigned in the variation pattern table for loss are composed of five types of normal variation, normal loss, super reach loss A, super reach loss B, and super reach loss C.

  A sub board 40 is electrically connected to the main board 30. The sub board 40 includes a sub CPU (lottery control means, effect image display control means) 41. The sub CPU 41 receives a change command indicating the change pattern determined by the change pattern lottery from the main CPU 31. The sub CPU 41 reads the image data from the sub memory 42 in response to the variation command, and displays the variation display of the symbol and the effect image on the liquid crystal display 18.

  The sub CPU 41 includes an effect image lottery unit 43. The effect image lottery unit 43 performs an effect image selection lottery using an electronic random number, determines whether or not to display the effect image in each of the four steps dividing the variation time of the symbol, and displays the effect image. If you decide to display, select the type. The effect image displayed at each step is, for example, “button push message notice” that prompts the operation of the effect button 21 in the first step, and “step-up notice that increases the expectation of hitting in the second step. "In the 3rd step, a large number of characters are displayed as a" group notice ", and in the 4th step, it is a" chance up notice during reach "that suggests that you have a high degree of expectation for winning. The effect image displayed by steps differs. In each step, any one of a plurality of types of effect images having different modes is displayed.

  The effect image selection lottery is performed using the first effect lottery tables 44a to 44d or the second effect lottery tables 45a to 45d. These are stored in advance in the ROM area of the sub memory 42. The first effect lottery tables 44a to 44d and the second effect lottery tables 45a to 45d are extracted by the effect image selection lottery so that at least one of the probability of displaying the effect image and the selection rate between the same effect images are different. "No display" indicating that any one of a plurality of types of effect images or no effect image is displayed is assigned to all the random values to be displayed, and each of the plurality of types of effect images and "No display" is at least one of them Is assigned to one random value. Further, in the first effect lottery tables 44a to 44d or the second effect lottery tables 45a to 45d, the selection ratios of effect images are different from each other according to the variation pattern selected in the variation pattern lottery (some may be the same). A selection ratio of effect images is set. In the effect image selection lottery, a random value extracted at random is collated with the first effect lottery tables 44a to 44d or the second effect lottery tables 45a to 45d to determine which one of the effect images assigned to the random number value is. By doing so, the effect image is selected.

  The first effect lottery table 44a is used in the effect image selection lottery for the first step among the four steps. Similarly, the first effect lottery table 44b is an effect image selection lottery for the second step, the first effect lottery table 44c is an effect image selection lottery for the third step, and the first effect lottery table 44d is an effect image selection lottery for the fourth step. Used in.

  Then, as shown in FIG. 3, in the first effect lottery table 44a, “no display”, “effect image A”, “effect” in the first step with a selection rate corresponding to the change pattern determined in the change pattern lottery. One of the four elements is assigned to all random numbers extracted in the effect image selection lottery so that either “image B” or “effect image C” is selected.

  Further, in the first effect lottery table 44b, “no display”, “effect image D”, “effect image E”, “effect image” in the second step at a selection rate according to the change pattern determined in the change pattern lottery. One of the four elements is assigned to all random numbers extracted in the effect image selection lottery so that any one of “F” is selected.

  Also, as shown in FIG. 4, in the first effect lottery table 44c, either “no display” or “effect image G” is selected in the third step at a selection rate according to the variation pattern determined in the variation pattern lottery. One of the two elements is assigned to all random numbers extracted in the effect image selection lottery.

  Furthermore, in the first effect lottery table 44d, either “no display” or “effect image H” is selected in the fourth step at a selection rate according to the variation pattern determined in the variation pattern lottery. One of two elements is assigned to all random numbers extracted in the effect image selection lottery.

  The second effect lottery table 45a is used in the effect image selection lottery for the first step. Similarly, the second effect lottery table 45b is an effect image selection lottery for the second step, the second effect lottery table 45c is an effect image selection lottery for the third step, and the second effect lottery table 45d is an effect image selection lottery for the fourth step. Used in.

  Then, as shown in FIG. 5, in the second effect lottery table 45a, “no display”, “effect image A”, “effect” in the first step with a selection rate corresponding to the change pattern determined in the change pattern lottery. One of the four elements is assigned to all random numbers extracted in the effect image selection lottery so that either “image B” or “effect image C” is selected.

  Further, in the second effect lottery table 45b, “no display”, “effect image D”, “effect image E”, “effect image” in the second step at a selection rate according to the change pattern determined in the change pattern lottery. One of the four elements is assigned to all random numbers extracted in the effect image selection lottery so that any one of “F” is selected.

  Also, as shown in FIG. 6, in the second effect lottery table 45c, either “no display” or “effect image G” is selected at the third step at a selection rate according to the variation pattern determined by the variation pattern lottery. One of the two elements is assigned to all random numbers extracted in the effect image selection lottery.

  Further, in the second effect lottery table 45d, either “no display” or “effect image H” is selected in the fourth step at a selection rate according to the variation pattern determined in the variation pattern lottery. One of two elements is assigned to all random numbers extracted in the effect image selection lottery.

  The sub CPU 41 includes a step selection lottery unit (step selection lottery means) 46. It is activated when you win in the winning lottery. The step selection lottery unit 46 performs step selection lottery using an electronic random number, and selects any one of the four steps of performing the effect selection lottery using the first effect lottery tables 44a to 44d. The step selection lottery is performed using a step selection table 47 stored in the ROM area of the sub memory 42 in advance. In the step selection table 47, any of the four steps is assigned to all random numbers extracted by the step selection lottery, and each step is assigned to at least one of the random values.

  As shown in FIG. 7, in the step selection table 47, each step is set to all random numbers extracted by the step selection lottery so that each step is selected at a selection rate according to the variation pattern determined by the variation pattern lottery. Is assigned.

  Next, the flow of the effect image selection process in each step will be described.

  As shown in FIG. 8, when the game ball launched into the game area 11 a by the turning operation of the launch handle 20 wins either the first start port 12 or the second start port 13, the winning lottery unit 35 wins. Run a lottery. When the winning lottery is completed, the fluctuation pattern lottery unit 36 executes a fluctuation pattern lottery corresponding to the result. When the variation pattern lottery is completed, a variation command indicating the result is transmitted from the main CPU 31 to the sub CPU 41. The sub CPU 41 identifies the winning lottery result and the variation pattern based on the variation command. In the case of winning, the step selection lottery unit 46 executes step selection lottery at a selection rate corresponding to the type of variation pattern. When the step selection lottery is completed, for the step selected in the step selection lottery, the effect image selection lottery is executed using the first effect lottery tables 44a to 44d, and other steps not selected in the step selection lottery are performed. For the step, the effect image selection lottery is executed using the second effect lottery tables 44a to 44d. On the other hand, if the winning lottery is lost, the step selection lottery is not performed, and the effect image selection lottery is executed for each step using the second effect lottery tables 44a to 44d. When the effect image selection lottery ends, the sub CPU 41 writes the result in the RAM area of the sub memory 32, and starts the variable display of symbols. During the variable display of symbols, the type of effect image to be displayed is identified while referring to the RAM area of the sub memory 32, the image data corresponding to the identified type of effect image is read, and the effect image is displayed at each step. .
