Lottery device and game device using the same

Technical Field

The present invention relates to a drawing machine which performs a drawing in accordance with a winning probability of each drawing object determined from winning probability data and determines a winning object from among a plurality of drawing objects, and a game machine using the drawing machine.

Background

A drawing machine for determining a winning target from a plurality of drawing targets is widely used in many fields. For example, as an example of a game device used in a game machine, a bingo game machine described in patent document 1 is known. In this bingo (bingo) game machine, a bingo card image (arrangement image) in which number images (drawing target images) are arranged in a 5 × 5 square matrix in a unique arrangement for each player is displayed on a display unit prepared for each player. Then, the drawing machine determines winning numbers (winning objects) from the 25 numbers (drawing objects) of "1" to "25", and the display form of the winning numbers and the other numbers in the bingo card image of each player is made different. Repeating the above operations a prescribed number of times, and paying a prize to the player when all the numbers arranged in the longitudinal, lateral and diagonal directions in the bingo card image are selected.

In the drawing machine used in such bingo game machine, it is important to give the drawing participant an impression that the drawing is performed impartially, regardless of whether or not the drawing is actually performed impartially. Therefore, in the bingo game machine described in the above patent document 1, a so-called drawing device for performing a physical drawing is used. Specifically, the drawing machine used in the bingo game machine includes a ball supply hole, a rotating body having a surface portion for rotating the ball, and a collection portion formed of a plurality of pockets for collecting the ball. The rotating body is rotated on a fixed plane by a rotation driving mechanism, and the ball supplied from the supply hole is irregularly rotated on the surface and flies out. 25 pockets are provided along the outer periphery of the rotating body in the circumferential direction. Therefore, the balls rolling in the circumferential direction on the rotating body enter any one of the pockets and are collected. Each bag is assigned with any one of the numbers "1" to "25", and the number assigned to the bag into which the ball falls is determined as the winning number. In the drawing machine for performing such a physical drawing, since the drawing participant can clearly grasp the drawing process, the drawing participant can be given an impression that the drawing is performed fairly.

However, such a drawing machine that performs physical drawing has a disadvantage of low degree of freedom in changing the winning probability of each drawing object.

That is, for example, in the drawing machine described in patent document 1, if the size of the pockets is changed by using the driving device or the number assigned to the pockets is changed, the winning probability of each drawing object may be changed. However, the size and number of bags is physically limited. Therefore, the winning probability of each drawing object must be changed within the limited range, and the degree of freedom in changing the winning probability is low.

On the other hand, so-called computer lottery in which winning objects are determined by executing a lottery program based on the winning probability of each lottery object determined by the winning probability data has been known. In such a drawing machine that performs the computer drawing, since the winning probability of each drawing object can be changed by changing the winning probability data, the degree of freedom in changing the winning probability is high.

However, in a conventional drawing device for performing a computer drawing, since a general drawing participant cannot grasp the drawing program, it is difficult for the drawing participant to have an impression that the drawing is performed impartially. In particular, when the winning probability data is changed to control the change of the winning probability of each drawing object, if the winning probability of each drawing object is arbitrarily changed while the drawing participants are unaware of it, the result of giving the drawing participants an uncomfortable feeling is caused, and it is more difficult for the drawing participants to give an impression that the drawing is performed fairly. When the winning probability data is changed to change the winning probability of each drawing object by controlling this, it is also considered that information indicating that the winning probability of each drawing object has changed is notified to the drawing participants. However, if only the information indicating that the winning probability of each drawing object has changed is notified, the drawing participant cannot know how the winning probability has changed, and the sense of incongruity of the drawing participant cannot be sufficiently eliminated, so that it is difficult for the drawing participant to have an impression that the drawing is performed fairly.

Disclosure of Invention

The present invention has been made in view of the above circumstances, and provides a drawing machine and a game machine using the drawing machine, which are capable of easily giving a drawing participant an impression that a drawing is performed fairly when a drawing is performed by changing a winning probability of each drawing object by a computer.

A game device according to a first aspect of the present invention is a game device for determining a winning object from a plurality of drawing objects, comprising: a winning probability data storage unit that stores winning probability data indicating a winning probability of each of the plurality of drawing objects; a drawing unit that performs a drawing in accordance with the winning probability of each drawing object determined by the winning probability data stored in the winning probability data storage unit and determines a winning object from the plurality of drawing objects; a winning probability data changing unit that changes the winning probability data stored in the winning probability data storage unit; a winning probability image display unit that displays a winning probability image indicating a winning probability of each drawing object determined by the winning probability data stored in the winning probability data storage unit; a winning probability display control unit that changes the winning probability image displayed on the winning probability image display unit to a winning probability image based on the changed winning probability data when the winning probability data is changed by the winning probability data changing unit, and a bet accepting unit that accepts a bet for a bet subject; and a bonus payout unit that pays out a bonus, wherein the game control unit determines whether or not a predetermined payout condition is satisfied based on a result of the drawing by the drawing unit, and controls the bonus payout unit to payout a bonus in an amount corresponding to the number of the bet target accepted by the bet acceptance unit when it is determined that the predetermined payout condition is satisfied, and further controls: a payout amount determining section configured to determine an amount of payout of the award paid out by the award payout section based on a drawing result including the drawing object whose payout probability data is increased by the award probability data changing section, when the predetermined payout condition is satisfied; the award payment unit increases the number of awards paid out when the predetermined payout condition is satisfied based on a drawing result including the drawing object whose winning probability data is reduced by the winning probability data change unit.

In this drawing device, a winning probability image display unit displays a winning probability image indicating each drawing object of the drawing unit. When the winning probability data is changed according to a certain condition to change the winning probability of the drawing object, the winning probability image displayed on the winning probability image display unit is changed to the winning probability image based on the changed winning probability data. Thus, when the drawing participant changes the winning probability data of the drawing object, the winning probability image displayed on the winning probability image display unit can be confirmed and changed to the winning probability image indicating the winning probability of each drawing object determined by the changed winning probability data. Since the winning probability image indicates the winning probability of each drawing object, it is possible to recognize how the winning probability of each drawing object changes specifically by confirming the change of such winning probability image.

In the drawing machine, the winning probability image may include image areas corresponding to the drawing objects, and the winning probability of each drawing object may be expressed according to the size of each image area.

In this drawing machine, the drawing participant can intuitively recognize how the winning probability of each drawing object changes specifically by looking at the change in the size of each image area constituting the winning probability image. This makes it easier to recognize how the winning probability of each drawing object changes in detail, and therefore, it is easier for the drawing participant to have an impression that the drawing is performed fairly.

In the drawing machine, the drawing unit may determine the winning objects from the drawing objects remaining after the winning objects determined in accordance with the drawing performed in the past in the predetermined period are removed from the plurality of drawing objects, and the winning probability data changing unit may determine the winning probabilities of the remaining drawing objects and change the winning probability data so that the winning probabilities of the remaining drawing objects become the determined winning probabilities, respectively, between the drawings performed by the drawing unit in the predetermined period.

In the drawing machine, for example, as in a drawing in a general bingo game, a series of drawings for removing a winning object determined by a drawing performed in the past from a drawing object are sequentially performed in a predetermined period. In such a drawing, the number of drawing objects to be drawn changes every time the drawing is performed, and thus the winning probability of each drawing object also changes. In the drawing machine, the drawing participants can intuitively recognize the change of the winning probability in each drawing in the series of drawings. Thus, when a series of drawings are performed in a predetermined period to remove winning objects determined by a drawing performed in the past from the drawing objects, the drawing participants can intuitively recognize the change of the winning probability in each drawing.

Another aspect of the present invention is a game device including: the drawing device and the game control unit control the progress of a game using a result of the drawing by the drawing unit of the drawing device.

In this game device, when a drawing participant participates in a computer drawing in which the winning probability of each drawing object changes, the drawing participant is likely to have an impression that the drawing is performed impartially, and therefore, the game reliability is improved.

Further, the game device includes a bet acceptance unit that accepts a bet (bet) to a bet target and a bonus payout unit that pays out an award, and the game control unit performs the following control: whether a predetermined payout condition is satisfied is determined based on a lottery result of the lottery section, and when it is determined that the predetermined payout condition is satisfied, the award paying section is caused to pay an award of an amount corresponding to an amount of the bet target accepted by the bet accepting section.

In this game device, a so-called betting game can be executed in which a drawing participant bets a betting object and receives an award determined to satisfy a predetermined payout condition based on a drawing result. In a betting game, it is generally important to give the participants of the lottery an impression that the lottery is performed fairly, because the main purpose of the participants of the lottery is to receive a prize. Therefore, in such a betting game, by making it easy for the game participants to have the impression that the drawing is performed fairly, the game performance of the betting game in which the game reliability is important can be greatly improved.

Further, in the game device, the game control unit may perform: when the winning probability data change unit of the drawing device increases the winning probability data, the amount of the prize paid by the prize payout unit is decreased, and when the winning probability data change unit decreases the winning probability data, the amount of the prize paid by the prize payout unit is increased.

In such a game device, when the winning probability data is changed by the winning probability data changing unit, the odds may be directly changed. Once the odds change, the management of the game balance becomes difficult, and stable and high game performance cannot be provided. In addition, in the case where the game apparatus is a business game apparatus installed in a casino such as a game center, and the participants are drawn to pay money and use a physical object such as a rental medal or electronic data corresponding to the physical object as a betting target or a bonus, it is important to maintain the odds ratio at a substantially constant level from the viewpoint of business management. Therefore, it is necessary to suppress the above-mentioned change in the odds.

In the game device, the payout amount is decreased when the winning probability data is increased and the payout amount is increased when the winning probability data is decreased, and therefore the winning probability data changing unit may make the odds substantially constant before and after the winning probability data is changed. Therefore, the game balance management becomes easy, and stable and high game performance can be provided. Further, when the game device is used as the game device for business, business management becomes easy.

Further, the game device includes: a prize amount determination data storage unit that stores prize amount determination data for each of the plurality of drawing objects, the stored prize amount determination data being used to determine the number of prizes paid out by the prize payout unit in accordance with the predetermined payout condition if the drawing object is subsequently determined as a winning object by the drawing unit; and a prize amount image display unit that displays a prize amount image indicating the prize amount of each of the lottery objects determined based on the prize amount determination data stored in the prize amount determination data storage unit. The game control unit performs the following control when the drawing unit determines that the drawing target is the winning target and a predetermined payout condition is satisfied: making the award paying section pay awards of the amount determined by the award amount determination data corresponding to the drawing object stored in the award amount determination data storage section; and also performs the following display control: the winning probability data changing unit controls the odds to be substantially constant before and after the winning probability data is changed by changing the winning amount determination data stored in the winning amount determination data storage unit, and changes the winning amount image displayed on the winning amount image display unit to a winning amount image based on the winning amount data after the change when the winning amount determination data is changed.

In this game device, when a winning object is determined by a drawing unit of the drawing device and a predetermined payout condition is satisfied, the award of the amount determined by the award amount data corresponding to the winning object is paid out. The control for making the set odds before and after the change of the winning probability data substantially constant is performed by changing the award amount determination data stored in the award amount determination data storage unit.

In this game device, the drawing participant can grasp which drawing object can receive a bonus when winning in the next drawing by viewing the bonus amount image. When the award amount determination data is changed under the condition that the odds ratio is substantially constant, the lottery participant can grasp the changed award amount by observing the award amount image. Thus, it is possible to prevent the award amount from changing by changing the award amount determination data while the lottery participant is unaware of the change, and it is possible to avoid the lottery participant from generating a sense of incongruity. The award amount image may be an image directly indicating the award amount or an image indicating the award magnification, as long as the player can grasp the award amount by observing the award amount image.

In the game device, the award amount image may have an image area corresponding to each drawing target, and the relationship between the amounts of award to the respective drawing targets may be expressed by a difference in color between the image areas.

In this game device, the drawing participants can understand the relationship in magnitude of the award amount for each drawing target based on the difference in color of each image region constituting the award amount image. Thus, it is possible to easily recognize how the award amount of each drawing object changes, and therefore, the reliability of the game is improved.

Further, the game device includes: an arrangement image display unit that displays an arrangement image in which a plurality of drawing-object images corresponding to some or all of the plurality of drawing objects are arranged; and a winning object storage unit that stores a conventional winning object determined by the drawing unit of the drawing machine during a period in which a drawing is performed a plurality of times by the drawing machine, wherein the game control unit performs control to cause the award payout unit to pay out the award when a plurality of winning objects stored in the winning object storage unit satisfy a predetermined payout condition that is a predetermined combination of winning objects corresponding to the plurality of winning objects stored in the winning object storage unit and when an arrangement of drawing object images in the arrangement image becomes a predetermined arrangement.

In this game device, a game such as a so-called bingo game, in which a payout is paid out when the arrangement of drawing object images corresponding to a plurality of winning objects is changed to a predetermined arrangement, can be executed. This can improve the reliability of a game in a bingo game or the like, which is a kind of a betting game.

According to the present invention, when a computer lottery is performed in which the winning probability of each lottery object changes, since the lottery participants can intuitively recognize how the winning probability of each lottery object specifically changes when the winning probability of the lottery object is changed, it is easy for the lottery participants to have an impression that the lottery is performed fairly.

The calculation process of the payout rate data is performed every time the lottery is finished for the fourth time or later by the lottery unit 105, and the payout rate is normally calculated so that the award amount decreases as the number of lottery increases. Although the details will be described later, the payout rate is calculated so that the award amount is reduced for the number for which the winning probability is increased by the winning probability changing unit 106. The calculated payout rate data is stored in a payout rate storage area of the RAM7, which is a payout amount determination data storage unit serving as a payout amount determination data storage means.

Fig. 7 is an explanatory diagram showing an example of a game screen displayed on the touch panel 11.

In this game screen, two bingo card images are displayed. The numbers surrounded by the square in each bingo card image indicate numbers that are winning in the drawing performed previously, and the numbers surrounded by the round indicate numbers that are not winning. Further, the display state of the number "16" located in the lower right corner in the bingo card image on the left side in the drawing is, as described later, a display state when the player touches the number and wishes to be selected, and the number is a selection-desired number. Also, the selection-desired number in the bingo card image on the right side in the figure is displayed as surrounded by a large circular frame.

Further, the following display fields and the like are displayed in the lowermost portion of the game screen: a BET display field 11a indicating the number of BET targets (the number of medals) BET by the player; a play point obtainment amount display section 11b that indicates the number of play points obtained by the occurrence of bingo; a play point display field 11c indicating the number of play points currently played by the player. Further, a winning record display column 11d is provided above the display column, and sequentially displays the numbers of winning in the previous drawing from the left side in the figure. In the illustrated example, the drawing has been performed 10 times before.

Further, a prize amount display column 11e is provided at the uppermost portion of the game screen. The prize amount display field 11e shows a relationship between the colors of the roulette wheel and prize amounts, which will be described later, and the prize amount of each color is obtained by multiplying the amount bet by the player by the payout rate data corresponding to each color.

Further, an attack instruction value display field 11f is displayed in the upper left portion of the game screen. The attack instruction value in the attack instruction value display field 11f increases as a result of satisfying a predetermined condition, and after the value becomes full, an attack operation described later can be performed. Details are set forth below.

Next, the operation of the present bingo game machine will be described according to the flow of the bingo game in the present embodiment.

FIG. 8 is a flowchart showing a flow of the bingo game.

In this bingo game machine, when a player inserts medals into the medal insertion port 13 of the station 10, the medal management device 18 detects the number of the inserted medals and stores the game points having the same size as the number of the inserted medals in the game point data. When the medal manager 18 detects that a medal is inserted, it notifies the controller 4 constituting the game progress control unit 101 of the detection of the medal.

Specifically, the game progress control unit 101 that has received the notice of the bet of medals outputs a bet screen display command to the station display unit 103. As a result, a betting screen is displayed on the touch panel 11 of the station 10 after the player has inserted the medals. In the bet display screen, two bet buttons, a 1-bet button and a 10-bet button, are displayed. The player bets a desired amount of game points by touching the bet buttons. When the player touches these bet buttons, bet data indicating the bet amount is transmitted from the input control device 17 to the game progress control unit 101. The game progress control unit 101 as a bet acceptance unit functions as a bet acceptance means, accepts a bet, and outputs a bet command to the token management device 18. Thus, the token management device 18 performs the following processing (S1): the number-of-tokens-size game dots relating to the bet command are subtracted, and the number-of-tokens-size game dots are added to the bet data. Thus, the player can bet the game points by touching the bet button of the desired bet amount size.

Further, upon receiving the BET data from the input control device 17, the game progress control unit 101 outputs a display command to the station display unit 103, and updates the BET display field 11a and the play point display field 11c in the game screen of the touch panel 11.

The game progress control unit 101 receives the bet data from the input control device 17, and then calculates the award amount corresponding to the bet data stored in the token management device 18 based on the 8 payout rate data stored in the payout rate storage area of the RAM 7. In the present embodiment, eight payout rate data of 1.5 times, 2.5 times, 3.5 times, 5 times, 8 times, 12 times, 20 times, and 30 times may be stored in the payout rate storage area of the RAM7 as basic payout rate data in association with each number. The game progress control unit 101 multiplies the medal data stored in the medal management device 18 by each of the payout rate data, and calculates the award amount corresponding to each of the payout rate data. Then, a display command is output to the station display unit 103 to update the award amounts displayed in the eight payout rate areas in the award amount display field 11e on the game screen of the touch panel 11 to the calculated award amounts. The eight payout area areas are represented by different colors, and each color corresponds to a color of a wheel described later.

After the betting acceptance is thus completed, the game progress control unit 101 outputs a card generation command to the card generation unit 102. Thus, the card generating unit 102 executes the arrangement determining program, generates the arrangement information of the two bingo cards, and stores the generated two arrangement information in the arrangement information storage area of the RAM 7. After the card generation unit 102 generates the arrangement information, the game progress control unit 101 reads the two pieces of arrangement information from the arrangement information storage area of the RAM7, and outputs a card display command based on the arrangement information to the station display unit 103. Thus, a bingo card image composed of two number images of "1" to "25" randomly arranged in a matrix of 5 × 5 is displayed on the touch panel 11 of the station 10 where the player places a bet (S2).

In the present embodiment, the case where two bingo card images are displayed on the touch panel 11 of one station 10 is described, but one bingo card image may be displayed, or three or more bingo card images may be displayed.

In this way, after the bingo card image is displayed on the touch panel 11 of the station 10, the 1 st to 4 th drawings are first performed (S3). Specifically, the game progress control unit 101 outputs a 1 st drawing start command to the drawing unit 105, and the drawing unit 105 performs a computer drawing in accordance with the winning probability of each number determined by the winning probability data stored in the winning probability storage area of the RAM7 to determine a winning number. To explain in more detail an example of the drawing process by the drawing unit 105, a predetermined random number range is divided into division areas corresponding to respective winning-losing numbers so that each winning-losing number which has not been won until then becomes a winning probability determined by the winning probability data stored in the winning probability storage area of the RAM 7. Therefore, in the drawing of the 1 st time, the division areas corresponding to the numbers "1" to "25" are allocated for a predetermined random number range. In the drawing of the 2 nd time, a predetermined random number range is divided into division areas corresponding to 24 non-winning numbers excluding the numbers won by the drawing of the 1 st time among "1" to "25". In the same manner, in the 3 rd drawing, the drawing is divided into division areas corresponding to non-elected numbers except for the previously elected number. If the winning probability is not changed by the winning probability changing process described later, the divided areas are equally divided. Then, after the predetermined random number range is divided in this way, a random number is generated, a division area to which the random number belongs is specified, and a number corresponding to the specified division area is determined as a winning number. The decided winning number is stored in the winning record storage area of the RAM 7.

Further, the game progress control unit 101 outputs a roulette wheel spin command to the main display unit 104. Thereby, the main display unit 104 rotates the roulette wheel of the roulette wheel image displayed on the large-format display 2, and performs a drawing demonstration.

Fig. 1A is an explanatory diagram showing an example of a main screen displayed on the large-format display 2 when "12" becomes the winning number in the drawing of the 1 st time. Fig. 1B is an explanatory diagram showing an example of the main screen before the drawing of the 11 th time is performed.

In this main screen, a roulette wheel image having an image area corresponding to a number not selected from "1" to "25" is displayed. Therefore, in the drawing demonstration of the 1 st time, as shown in fig. 1A, the wheel images having the image areas corresponding to all the numbers in "1" to "25" are displayed, in the drawing demonstration of the 2 nd time, the wheel images having the image areas corresponding to the 24 numbers excluding the number elected in the drawing of the 1 st time in "1" to "25" are displayed, and in the drawing demonstration of the later times, the wheel images having the image areas corresponding to the numbers excluding the number elected previously are displayed. Fig. 1B is a main screen showing a roulette wheel image for demonstration in the drawing at the 11 th time after the numbers "12", "19", "2", "24", "21", "5", "22", "17", "8" and "11" are won in the drawings at the 1 st to 10 th times as shown in fig. 7.

Here, the difference in the image area size of each number in the wheel image on the large-sized display 2 is used to express the winning probability of each number. If the winning probability is not changed by the winning probability changing process described later, the winning probabilities of the numbers are equal, and therefore the sizes of the image areas of the numbers in the roulette image are equal to each other. However, in the present embodiment, each drawing performed by the drawing unit 105 that performs the drawing 12 times (predetermined period) in one bingo game is determined as the winning number from the numbers other than the winning number determined by the drawing performed in the past as described above. Therefore, even if the winning probability of each non-winning number is equal in each drawing, the winning probability of each non-winning number is gradually improved as the number of times of drawing increases.

Specifically, before the 1 st drawing is started, winning probability data in which the winning probabilities of the 25 numbers are all equal is stored in advance in the winning probability storage area of the RAM 7. After the 1 st drawing is finished using the winning probability data, the game progress control unit 101 outputs a winning probability change command to the winning probability changing unit 106 before outputting a 2 nd drawing start command to the drawing unit 105. Thus, the winning probability changer 106, which is a winning probability data changer, functions as a winning probability data changer, and changes the winning probability data stored in the winning probability storage area of the RAM7 so that the respective winning probabilities of the 24 non-winning numbers are all equal in accordance with the winning probability change command. By this change, in the drawing process of the 2 nd time by the drawing unit 105, each divided region corresponding to the number not elected in the predetermined random number range is equally expanded. Thus, in the 2 nd drawing, the winning probability of each non-winning number is also higher than that in the 1 st drawing. After that, the game progress control unit 101 outputs a 2 nd drawing start command to the drawing unit 105. The game progress control unit 101, which is a winning probability display control unit, functions as winning probability display control means, and outputs a roulette wheel change display command to the main display unit 104. The main display unit 104, having received the wheel change display command, displays a wheel image having an image area of a size corresponding to each winning probability on the large-format display 2 in association with the 24 numbers not yet paid for. Here, since the respective winning probabilities are equal, the roulette wheel image is provided with 24 image areas having an equal size. Thereafter, the game progress control unit 101 outputs a 2 nd drawing start command to the drawing unit 105, and performs the 2 nd drawing.

In addition, the color of the image area of each number in the wheel image on the large-sized display 2 corresponds to the award amount of each number. That is, the color of the image area of each number corresponds to the color of the eight payout rate areas of the award amount display field 11e displayed on the game screen of the touch panel 11 of the station 10. Therefore, the player can easily grasp the winning of each number in the next drawing by looking at the color of each number in the roulette image on the large-sized display 2, thereby completing the award amount paid out when bingo is completed.

The game progress control device 101 outputs each drawing start command of the 2 nd time to the drawing unit 105, and then outputs a wheel rotation command to the main display unit 104. Upon receiving the wheel rotation command, the main display unit 104 rotates the wheel of the wheel image displayed on the large-format display 2 to show that the drawing is being performed. Thereafter, the game progress control unit 101 reads the winning number stored in the winning record storage unit of the RAM7, and outputs a demonstration display command indicating that the number is winning to the main display unit 104. As a result, the main display unit 104 makes a demonstration, as shown in fig. 1A, of a number image in which the winning number appears in the middle of the wheel image displayed on the large-format display 2. In the example shown in fig. 1B, "12" is the winning number. That is, the main display unit 104 as the notification unit functions as a notification means for notifying the player of the winning number each time the winning number is determined by the drawing unit 105.

The game progress control unit 101, which reads the winning number stored in the winning record storage unit of the RAM7, outputs a display command to the station display unit 103, updates the winning record display field 11d on the game screen of the touch panel 11, and changes the number image corresponding to the winning number in the bingo card image from the number surrounded by the circular frame to the number surrounded by the square frame. That is, the station display unit 103 as the notification unit also functions as a notification unit that notifies the player of the winning number each time the winning number is determined by the drawing unit 105.

The above drawing process is repeated up to the 4 th time, and after the 4 th drawing is performed, the game progress control unit 101 outputs a determination command to the bingo determination unit 107. Thus, the bingo determination unit 107 performs the above-described listen-up (リ - チ) determination process (S4). In the hearing determination (リ - チ) process, when it is determined that hearing has occurred, the bingo determination unit 107 transmits hearing occurrence information to the game progress control unit 101, and the game progress control unit 101 creates a hearing table for the corresponding arrangement information (S5).

Then, the game progress control unit 101 performs the winning probability changing process of the winning desired number that the player wishes to win (S20). The selection probability changing process is performed every time the 4 th, 6 th, 8 th, and 10 th drawings are completed. The selection probability changing process will be described in detail later.

Next, the game progress control unit 101 performs the 5 th drawing to determine the 5 th winning number (S6). Then, the game progress control unit 101 outputs a determination command to the bingo determination unit 107 to cause the bingo determination unit 107 to perform the bingo determination process (S7). This bingo determination process determines whether bingo has occurred, based on the winning numbers (5 winning numbers at the present time) stored in the winning record storage area of the RAM7 and the arrangement information stored in the arrangement information storage area of the RAM 7. When it is determined that bingo has occurred, the bingo determination section 107 transmits bingo occurrence information to the game progress control section 101. The game progress control unit 101 that has received this information outputs a payout command to the token management device 18 to instruct payout of the award amount of the size of the payout rate area corresponding to the winning number that was won in the 5 th drawing. The token management device 18 that has received the payout command temporarily stores the award amount related to the payout command, and performs a process of adding game points of the award amount to the game point data at the time when the bingo game is ended (S8).

Further, the bingo determination unit 107 that has received the determination command performs the above-described listen-up determination process (S9), and if it is determined that a listen-up has occurred, creates a listen-up table for the corresponding array information (S10).

Then, the game progress control unit 101 outputs a payout rate calculation command to the payout rate management unit 108. In this way, the payout rate management unit 108 updates the payout rate data of each number (S11). Specifically, the return rate data is calculated for each non-elected number that is not elected in the previous election. The calculated rate of return data is stored in the rate of return storage area of the RAM7 in association with the corresponding elected number. In the present embodiment, when the 4 th drawing is finished, basic payout rate data of 30 times is selected for all 21 non-winning numbers. That is, the rate of return when binned fruit is established in the 5 th decimation is 30 times. If the payout rate data is not changed in the winning probability changing process described later, the basic payout rate data one step lower than the current basic payout rate data is selected for each non-winning number and stored in the payout rate storage area of the RAM7 when the drawing after the 5 th time is completed. Therefore, if the payout rate data is not changed in the winning probability changing process described later, the basic payout rate data 20 times lower by one step than the current basic payout rate data 30 times is uniformly selected for all the 20 non-winning numbers when the 5 th drawing is ended, and the basic payout rate data lower by one step is also sequentially uniformly selected after the subsequent drawing is ended. Since the probability of bingo increases as the number of drawings increases, the odds can be maintained substantially constant by changing the payout rate data every time the drawing after the 5 th drawing is ended.

Here, when the 4 th, 6 th, 8 th, and 10 th drawing presentations are finished, the award amount displayed in the award amount display field 11e on the game screen 11 of the station 10 is updated. Then, until the three numbers on the same line on the bingo card image displayed on the game screen become the winning numbers, the prize amounts corresponding to the basic rate of return data are displayed in the areas corresponding to the respective colors of the prize amount display field 11 e. On the other hand, when the prize amount display field 11e is updated, if three or four numbers on the same line on the bingo card drawing are the winning numbers, the prize amount corresponding to the real payout rate data is displayed in the area corresponding to each color of the prize amount display field 11 e. The actual payout rate data is calculated by the payout rate management unit 108 based on the probability of the achievement of a bingo in the following two drawings (drawings performed before the next award amount display field 11e is updated). Specifically, the true payout rate data is calculated based on the winning probability of each number at the time of the update (when the winning probability data is changed by the winning probability changing process described later, this is the winning probability after the change) and the arrangement relationship of the numbers on the matrix array obtained based on the arrangement information corresponding to the bingo card image displayed on the touch panel 11 of the station 10 at the time of the update. By this processing, the award amount displayed on the award amount display section 11e is changed from the award amount based on the basic rate of return data to the award amount based on the real rate of return data on the touch screen 11 of the station 10 for displaying the bingo card image in which three or four numbers on the same line are the elected numbers at the time of updating the award amount display section 11 e. As a result, when three or four numbers on the same line become the elected number, the touch panel 11 of each station 10 displays the respective award amounts on the award amount display section 11 e. That is, the number and color of each payout rate area divided by color on the payout amount display field 11e are common to all the stations 10, but the payout amount displayed in each payout rate area differs from station to station.

In this way, after the payout rate management unit 108 stores the payout rate data of each non-winning number in the payout rate storage area of the RAM7, the game progress control unit 101 serving as the winning probability display control unit functions as a winning probability display control means, and outputs a roulette wheel change display command to the main display unit 104. The main display unit 104 that has received the roulette wheel change display command functions as a winning probability image display unit and a payout amount image display unit, and displays on the large-format display 2 a roulette wheel image having image areas of the current non-winning number (20 numbers at the end of the 5 th drawing) and the color of each image area corresponding to the payout rate data updated in S11 (S12).

Then, the game progress control unit 101 determines whether or not the number of drawings completed up to this point is any of the 6 th, 8 th, and 10 th drawings (S13). When the player determines that the number is any one of the 6 th, 8 th and 10 th numbers, the winning probability changing process is executed for the winning desired number that the player wishes to win (S20). That is, in the present embodiment, the winning probability changing process is performed every time the 4 th, 6 th, 8 th, and 10 th drawings are completed. On the other hand, when it is determined that the drawing number is not any of the 6 th, 8 th, and 10 th, the game progress control unit 101 determines whether or not the drawing number which has been completed up to that time has reached 12 (S14), and when it is determined that the drawing number has not reached 12, the next process is executed without executing the winning-probability changing process (S6). On the other hand, when it is determined that the number of times reaches 12, the bingo game is ended.

After the game is completed, the medal management unit 18 executes a process of adding the payout amount size of the medal that is temporarily stored after the payout command is received in the bingo game to the game point data. Thereby, the amount of the game dots displayed in the game dot display field 11c becomes the added game dot amount.

Next, the winning probability changing process of the winning desired number which the player wishes to win will be described.

Fig. 9 is a flowchart showing the flow of the election probability changing process.

In the present embodiment, after the drawings of the 4 th, 6 th, 8 th, and 10 th drawings are finished, the game progress control unit 101 outputs a display command for displaying a descriptive digital image for reminding the player of touching the desired winning number to the station display unit 103. As a result, the station display unit 103 displays a text image such as "please touch the desired number" on the game screen of the touch panel 11 as shown in fig. 7. The player who sees the explanation digital image selects one of the number images of the non-selected number of the bingo image displayed on the game screen of the touch panel 11 within the limited time, and touches the number. Then, the input control device 17 outputs the desired number information indicating the touched number, and the desired number information is received by the game progress control unit 101 (S21). When the winning-desired number information is not received within the limited time, the winning probability changing process is directly ended.

The game progress control unit 101 as the desired drawing object determination unit functions as a desired drawing object determination means after receiving the desired number-to-be-selected information, and determines a desired number to be selected as a desired selection object that the player desires to select. Then, the election probability changing unit 106 outputs an election probability changing command. Thus, the winning probability changer 106, which is the winning probability data changer, functions as a winning probability data changer that changes the winning probability data stored in the winning probability storage area of the RAM7 so as to increase the winning probability of the winning desired number related to the winning probability change command (S22). By the above change, in the drawing process performed by the drawing unit 105, the division corresponding to the winning-desired number within the predetermined random number range is expanded, and the division of the remaining non-winning numbers is uniformly narrowed. Thereby, the electing probability of the elected desired number is improved.

Here, in the present embodiment, a maximum of seven players can simultaneously participate in the bingo game. Thus, the input control device 17 of each of the plurality of stations 10 may receive different pieces of the desired selection number information. Even in this case, the game progress control unit 101 outputs the winning-probability change command for each piece of the winning-desired number information. Thus, the winning probability changer 106 changes the winning probability data stored in the winning probability storage area of the RAM7 so as to increase the winning probability of the winning desired number associated with each winning probability change command. As a result, in the drawing process performed by the drawing unit 105, the division areas corresponding to the winning-desired numbers within the predetermined random number range are expanded, and the division areas of the remaining non-winning numbers are uniformly narrowed. Therefore, the more the information of the electing desired number is accepted, the higher the electing probability thereof. However, when the winning-wish-number information of a plurality of players is received, if the winning-wish-number information of a large number of players is collected into one number, the winning probability of another number may be lowered even if the winning-wish-number information relating to the other number is received.

Further, the game progress control unit 101 outputs a payout rate calculation command to the payout rate management unit 108. Thus, the payout rate manager 108 reads out the winning probability data changed in the above-described S22 from the winning probability storage area of the RAM7, and performs a process of changing the payout rate data in the payout rate storage area of the RAM7 based on the winning probability data (S23). Specifically, before and after the change of the winning probability data in S22, the payout rate data assigned to each of the non-winning numbers is changed so that the payout rate becomes substantially constant. Accordingly, the payout rate data of each non-elected number is changed so that the payout rate data of the non-elected number, which is increased by the change in S22, is relatively decreased.

Then, the game progress control unit 101 as the winning probability display control unit functions as a winning probability display control means for outputting to the main display unit 104 a roulette wheel change display command for changing the size of the image area of each non-winning number in the roulette wheel image to the size corresponding to the changed winning probability and changing the color of the image area of each non-winning number to the color corresponding to the changed payout rate data based on the changed winning probability data. Thus, the main display unit 104 functions as a winning probability image display unit and a bonus amount image display unit, and displays a roulette image on the large-sized display 2, in which the size of the image area of each non-winning number of the roulette image is the size corresponding to the changed winning probability, and the color of the image area of each non-winning number is changed to the color corresponding to the changed payout rate data (S24). As a result, as shown in fig. 10, a roulette wheel image in which the size of the image area of each of the unselected numbers is changed to a different size is displayed on the main screen of the large-format display 2.

By performing the winning probability changing process described above, the player can confirm the previous winning number while looking at the bingo card image displayed on the touch panel 11, and can increase the winning probability of the desired winning number by touching the image of the own desired winning number desired to be won such as the number required to establish bingo.

In the present embodiment, the winning probability of each number can be grasped from the size of the image area of the roulette image. When the player touches the image of the desired winning number on the touch panel 11 desired to be won and increases the winning probability of the desired winning number, the size of the image area of the desired winning number on the roulette wheel image is enlarged in accordance with the above situation. This makes it possible for the player to intuitively grasp that the winning probability of the number that the player wishes to win is improved. Further, the color of the image area of the selected desired number in the roulette image is simultaneously changed to the color corresponding to the changed payout rate data, so that the player can intuitively grasp the changed payout amount.

In the present embodiment, each time the winning desired number which the player wishes to win is won, the attack indication value in the attack indication value display field 11f displayed in the upper left part of the game screen on the touch panel 11 is increased, and the attack operation is performed after the attack indication value becomes full. Specifically, when the attack indication value becomes a full value, the player touches the winning-wish-number image on the touch panel 11 when the winning-probability changing process is performed, and then presses the attack button 12 (attack operation), and the game progress control unit 101 receives the winning-wish-number information every time the game progress control unit receives the information. That is, during the one-time winning probability changing process, the game progress control unit 101 receives a plurality of pieces of winning-wish number information from one station 10 for the same number. Thus, the player who can perform the attack operation can increase the winning probability of the winning number that the player wishes to win by pressing the attack button 12 at the time of the winning probability changing process. Here, in addition to the condition that the attack indication value becomes full, a condition for performing such an attack operation may be added. For example, a condition that an audible chart is satisfied with respect to the arrangement information corresponding to the bingo card image displayed on the touch panel 11 of the station 10 may be added.

In the present embodiment, when the player touches the winning desired number on the touch panel 11 at the time of the 4 th, 6 th, 8 th, and 10 th drawings being completed, the input control device 17 outputs the information of the winning desired number, and the game progress control unit 101 receives the information of the winning desired number, thereby increasing the winning probability of the winning desired number. The winning probability after the change is maintained until the next winning probability changing process is performed, and is reset when the next winning probability changing process is performed. That is, for example, when the winning probability of the winning-desired number is increased at the end of the 4 th drawing, the 5 th and 6 th drawings perform the drawing in a state where the winning probability of the winning-desired number is high, but the winning probabilities of all the non-winning numbers are reset to be equal at the end of the 6 th drawing. The same applies to the case where the winning probability of the winning desired number is increased at the end of the 6 th, 8 th, and 10 th drawings.

Fig. 11 is a flowchart showing the flow of attack processing.

The attack process is started after the 4 th and subsequent drawings are finished. When the winning desired number in the state in which the winning probability is improved is won by the drawing (S31), the game progress control unit 101 executes a process of increasing the attack indication value stored in the attack indication value storage area of the RAM7 by a predetermined amount (S32). Further, the game progress control unit 101 outputs a display command to the station display unit 103 to increase the attack instruction value in the attack instruction value display field 11f on the game screen of the touch panel 11.

After that, when the drawings of the 4 th, 6 th, 8 th, and 10 th drawings are finished, that is, when the starting condition of the winning probability changing process is satisfied (S33), the game progress control unit 101 determines whether or not the attack indication value data stored in the attack indication value storage area of the RAM7 has reached a predetermined amount (full value) (S34). When it is determined that the current winning probability is not the full value, the winning probability of the selected desired number can be increased by the normal winning probability changing process (S20). On the other hand, when it is determined that the value is full, the game progress control unit 101 permits the attack operation in the corresponding station 10 (S35). Specifically, the game progress control unit 101 outputs a display command to the station display unit 103 to display a descriptive digital image for prompting the player to touch a desired number to be selected, and then to press the attack button 12. Thereby, the station display unit 103 displays the descriptive digital image of the information on the game screen of the touch panel 11. The player who has viewed the digital image of the description selects one of the number images of the numbers not selected among the bingo images displayed on the game screen of the touch panel 11 within the limited time (S38), touches the selected number, and then presses the attack button 12 as many times as possible (S36). Then, the winning-desiring-number information indicating the touched number, which is the number of times the attack button 12 is pressed, is output from the input control device 17 (S37), and the winning-desiring-number information is received by the game progress control unit 101.

The game progress control unit 101, which is the fluctuation amount determination unit that has received the winning-wish-number information, functions as fluctuation amount determination means for determining the increase amount of the winning probability of the winning-wish-number according to a predetermined fluctuation amount determination condition that the increase amount of the winning probability of the winning-wish-number desired by the player who plays the game at the station of the output side is larger as the number of pieces of the winning-wish-number information is larger, and the winning probability changing unit 106 changes the winning probability data so that the winning probability of the winning-wish-number is increased by the increase amount. In the present embodiment, in the normal election probability changing process, only one piece of election desired number information can be output from one station 10, but when an attack operation is performed, a plurality of pieces of election desired number information can be output from one station 10 for the same election desired number. Thus, according to the attack process, the winning probability of the winning desired number can be significantly increased as compared with the case of the normal winning probability changing process.

In the present embodiment, the winning probability of the winning desired number is increased only after the attack button 12 is pressed in the attack processing, but a bet may be added when the attack button 12 is pressed. Fig. 12 shows a flowchart in this case.

As shown in fig. 12, in the attack process, the player presses the attack button 12(S36), outputs the elected desired number information (S37), and also outputs the additional bet signal (S39). The additional bet signal is transmitted to the game progress control unit 101, and the game progress control unit 101 as a bet acceptance unit functions as a bet acceptance means, accepts a bet, and outputs a bet command to the token management device 18. Thus, the token management device 18 performs the following processing: a predetermined number (for example, one piece) of game dots are subtracted from the game dot data, and the number of game dots is added to the bet data. That is, in this example, the game progress control unit 101 as the fluctuation amount determination unit functions as fluctuation amount determination means for determining the increase amount of the winning probability of the winning desired number according to a predetermined fluctuation amount determination condition that the increase amount of the winning probability of the winning desired number becomes larger as the number of game spots to which betting is applied increases and the winning probability of the winning desired number increases by the increase amount, and the winning probability changing unit 106 changes the winning probability data so that the winning probability of the winning desired number increases by the increase amount.

In general, the greater the amount of bet spots, the higher the risk of losing spots. According to the present invention, since the higher the winning probability of the winning desired number, the higher the risk of losing the game point, a good game balance can be obtained as compared with a case where only the winning probability of the winning desired number is simply increased.

The attack operation described above may be performed when the 4 th, 6 th, 8 th, and 10 th drawings are completed, but may be performed after the bingo card image is displayed on the touch panel 11 of the station 10 and before the winning number determined in the 1 st drawing is notified. This is because, before the winning number of the 1 st time is notified, there is a case where the player who sees the bingo card image wants to win a number arranged at a position advantageous for bingo establishment or a position preferred by the player.

In the example shown in fig. 12, the winning-desired number that the player who wishes to win with a large amount of additional betting is set to have a high winning probability, but it may be set to: when the Bingo game is started, the mode that the winning probability is high is selected by the winning-hoped number which is hoped to be selected by the player with a large bet amount. Fig. 13 shows a flowchart in this case.

As shown in fig. 13, the game progress control unit 101 as the fluctuation amount determination unit functions as fluctuation amount determination means when the winning desired number information is received (S21), and increases the amount of the game spots bet on the station 10 of the sender of the winning desired number information. The increasing amount of the winning probability of the winning desired number is determined under the predetermined fluctuation amount determination condition that the increasing amount of the winning probability of the winning desired number is larger (S25). Specifically, the game progress control unit 101 that has received the winning-wish-number information acquires, from the medal management device 18, the amount of the bet made at the station 10 that is the sender of the winning-wish-number information. Then, based on the amount of the game points, the increase amount of the winning probability is determined so that the more the amount of the game points, the greater the winning probability of the winning desired number. Then, the game progress control unit 101 outputs a winning probability change command to the winning probability changing unit 106, and the winning probability changing unit 106 changes the winning probability data stored in the winning probability storage area of the RAM7 so that the winning probability of the selected desired number is increased by the increase amount associated with the winning probability change command (S22).

In the example shown in fig. 13, the degree of improvement of the winning probability according to one winning-wish-number information is changed depending on the amount of the bet made at the station 10 of the sender of the winning-wish-number information. That is, the winning probability of the winning desired number is increased for the player who has a high risk of losing the game point. Therefore, a good balance of the game can be obtained as compared with the case of merely increasing the winning probability of the winning desired number.

Next, another example of modifying the degree of improvement of the winning probability by one piece of winning-desired number information will be described.

Fig. 14 is a flowchart showing a flow of the election probability changing process according to the present example.

When the preferred number information is received (S21), the game progress control unit 101 determines whether or not the listen-up table is established for the arrangement information corresponding to the station 10 of the sender of the preferred number information (S26). When the hearing table is not satisfied, the game progress control unit 101 as the fluctuation amount determination unit functions as fluctuation amount determination means to determine the increase amount of the winning probability of the selected desired number to be a small increase amount (S27). On the other hand, when the hearing table is established, the game progress control unit 101 as the fluctuation amount determination unit functions as fluctuation amount determination means, and determines the increase amount of the winning probability of the selected desired number to be a large increase amount (S28). That is, the game progress control unit 101 determines the increase amount of the winning probability of the winning desired number according to a predetermined fluctuation amount determination condition that the increase amount of the winning probability of the winning desired number is different between the listening state and the non-listening state. Then, the game progress control unit 101 outputs a winning probability change command to the winning probability changing unit 106, and the winning probability changing unit 106 changes the winning probability data stored in the winning probability storage area of the RAM7 so that the winning probability of the winning desired number is increased by the increase amount associated with the winning probability change command (S22).

In the example shown in fig. 14, the degree of increase in the winning probability by one piece of winning-desiring number information is changed depending on whether or not the ranking information hearing table corresponding to the station 10 of the sender of the winning-desiring number information is established. In detail, the player who is listening can increase the winning probability of his/her winning desired number. Therefore, the probability of winning the desired number differs between the listening state and the non-listening state, and the player's advantages and disadvantages are different, thereby improving the game quality.

In addition, although the description has been given by taking as an example the case where the present invention is applied to a bingo game machine, which is a token-operated game machine, as a business game device, the present invention is also applicable to other game devices such as a home game machine and a coin game machine which perform lottery by using a computer, or to a device which performs lottery by using a computer other than a game device, as well as to a bingo game machine.

In the above description, the case where the winning probability of the winning desired number which the player wishes to win is changed is described as an example, but the winning probability of the winning desired number which the player wishes to drop may be set.

In the above description, a multiplayer-participating game device in which seven players can participate simultaneously at maximum is taken as an example, but the same is true for a game device in which only one player participates.

Further, a plurality of bingo game machines may be connected via a network to perform a bingo game in which the same drawing result is used by the plurality of bingo game machines. In this case, the winning information of the non-winning number is changed based on the winning desire information of seven or more players, and the game quality due to the change of the winning probability is further improved.

Further, a part of the configuration of the bingo game machine may be provided in a communication terminal such as a telephone with a data communication function held by a player. In this case, it is necessary to provide a communication unit as communication means for performing data communication between the communication terminals via a network in the bingo game machine.

As a specific example, a wheel image (winning probability image) displayed on the large-sized display 2 may be displayed on a display unit as a display unit of the communication terminal. In this example, data for causing the display unit of the communication terminal to display the wheel image is transmitted from the communication unit to the communication terminal via the network. When the winning probability changing unit 106 changes the winning probability data, the communication unit transmits data for changing the wheel image displayed on the display unit of the communication terminal to an image based on the changed winning probability data to the communication terminal via the network. Thus, the player can confirm the roulette wheel image by looking at the display of the communication terminal held by the player without looking at the large-sized display 2. Further, if the communication terminal is configured such that all images displayed on the large-sized display 2 are displayed on the display portion thereof, the large-sized display 2 does not need to be provided.

As another specific example, an operation of selecting a number that the player wishes to select is performed not by the touch panel 11 of the station 10 but by an operation unit that is operation means of a communication terminal. In this example, settings are: for example, when a player operates an operation unit of a communication terminal and selects a number desired to be selected, desired number information is transmitted from the communication terminal. Then, when the communication unit receives the selection desired number information, the game progress control unit 101 determines a selection desired number that the player desires to select based on the received selection desired number information.

As another example, a case where all the components included in the station 10 are provided in the communication terminal may be mentioned. In this case, the player can play the game using the communication terminal held by the player without using the station 10. However, in this case, since it is difficult for the communication terminal to have a mechanism for accepting and paying out medals such as the medal insertion slot 13 and the medal acquisition slot 14, it is provided to perform betting and payout of awards using the game point data without using medals.
