Each pocket is assigned any number from “1” to “25”, and the number assigned to the pocket containing the ball is determined as the winning number. According to the lottery apparatus that performs such physical lottery, since the lottery participant can clearly grasp the lottery process, the lottery participant can easily recognize that the lottery is being performed fairly. .

However, the lottery apparatus that performs such physical lottery has a problem that the degree of freedom in changing the winning probability of each lottery object is low.
That is, for example, in the case of the lottery device described in Patent Document 1, for example, if the size of the pocket is changed using the driving mechanism or the number assigned to the pocket is changed, the winning probability of each lottery object is determined. It is also possible to change. However, the size and number of pockets are physically limited. Therefore, the winning probability of each lottery object must be changed within the limited range, and the degree of freedom in changing the winning probability is low.

  On the other hand, there is conventionally known a so-called computer lottery in which a winning object is determined by executing a lottery program according to a winning probability of each lottery object determined by winning probability data. A lottery apparatus that performs such a computer lottery can freely change the winning probability of each lottery object by changing the winning probability data, and thus has a high degree of freedom in changing the winning probability.

In this reach determination process, bingo is generated when a specific number is won next from the winning number stored in the winning history storage area of the RAM 7 and the array information stored in the array information storing area of the RAM 7. It is determined that the reach has occurred in the reach state. If it is determined that a reach has occurred, the bingo determination unit 107 sends reach occurrence information indicating that a reach has occurred to the game progress control unit 101.

  The odds management unit 108 includes the computer lottery device 20, the RAM 7, the ROM 8, the auxiliary storage device 9, and the like in the hardware configuration shown in FIG. When the odds management unit 108 receives the odds calculation command from the game progress control unit 101, for each number, if the number is the winning number determined next by the lottery unit 105, the payout condition that bingo is established Odds data, which is payout amount determination data for determining the amount of payout to be paid out when satisfying the above, is calculated. The odds data calculation process is performed every time the lottery unit 105 finishes the fourth lottery and usually the odds are calculated so that the payout amount decreases as the number of lotteries increases. As will be described in detail later, the odds are calculated so that the payout amount is reduced for the number whose winning probability is increased by the winning probability changing unit 106. The calculated odds data is stored in an odds storage area of the RAM 7 as a payout amount determination data storage means.

FIG. 7 is an explanatory diagram illustrating an example of a game screen displayed on the touch panel 11.
Two bingo card images are displayed on this game screen. The number enclosed in the square frame in each bingo card image indicates the number won in the lottery conducted so far, and the number enclosed in the round frame indicates the number that has not been won yet. . In addition, the display form of the number “16” located in the lower right corner of the bingo card image on the left side in the figure is a display form when the player touches the number and wishes to win, as will be described later. This is the winning number. Note that the winning number in the bingo card image on the right side of the figure is displayed surrounded by a large round frame.

Further, at the bottom of the game screen, a BET display column 11a indicating the amount of credit (medal amount) that is a betting object bet by the player, a credit acquisition amount display column 11b indicating a credit amount acquired by the occurrence of bingo, A credit display column 11c indicating the current credit amount of the player is displayed. In addition, above these display columns, there is provided a winning history display column 11d that sequentially displays the numbers won in the lottery up to the present from the left side in the drawing. In the example shown in the drawing, a state in which ten lotteries have been performed so far is shown.
A payout amount display column 11e is displayed at the top of the game screen. This payout amount display column 11e shows the relationship between roulette color and payout amount, which will be described later, and the payout amount of each color is obtained by multiplying the odds data corresponding to each color by the bet amount of the player. .
An attack gauge display field 11f is displayed at the upper left of the game screen. The attack gauge in the attack gauge display field 11f increases when a predetermined condition is satisfied, and when the tank is full, an attack operation described later can be performed. Details will be described later.

Next, the operation of the bingo game machine will be described according to the flow of the bingo game in the present embodiment.
FIG. 1 is a flowchart showing the flow of a bingo game.
In this bingo game machine, when a player inserts a medal into the medal insertion slot 13 of the station 10, the medal insertion number is detected by the medal management device 18, and credits corresponding to the medal insertion number are stored in the credit data. Further, when the medal management device 18 detects the insertion of a medal, the medal management device 18 notifies the controller 4 constituting the game progress control unit 101 to that effect.

  Specifically, the game progress control unit 101 that has received notification that a medal has been inserted outputs a bet screen display command to the station display unit 103. Thereby, a bet screen is displayed on the touch panel 11 of the station 10 where the player has inserted medals. On this bet screen, two bet buttons, a 1 bet button and a 10 bet button, are displayed. The player bets a desired amount of credit by touching these bet buttons. When the player touches these bet buttons, bet data indicating the bet amount is sent from the input control device 17 to the game progress control unit 101. The game progress control unit 101 functions as a bet receiving unit, receives a bet, and outputs a bet command to the medal management device 18. Thereby, the medal management device 18 performs a process of subtracting the credits corresponding to the bet command and adding the credits corresponding to the bet number to the bet data (S1). In this way, the player can bet credits by touching the bet button for the desired number of bets.

When the game progress control unit 101 receives 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 displays the BET display column 11 a and the credit display column 11 c on the game screen of the touch panel 11. Update.
Further, when the game progress control unit 101 receives the bet data from the input control device 17, the game progress control unit 101 responds to the bet data stored in the medal management device 18 based on the eight odds data stored in the odds storage area of the RAM 7. Calculate the dividend amount. In this embodiment, eight odds data of 1.5 times, 2.5 times, 3.5 times, 5 times, 8 times, 12 times, 20 times, and 30 times correspond to each number as basic odds data. It is stored in the odds storage area of the RAM 7 so that it can be attached. The game progress control unit 101 multiplies the bet data stored in the medal management device 18 by each odds data, and calculates a payout amount corresponding to each odds data. Then, a display command is output to the station display unit 103 to update the payout amounts displayed in the eight odds categories in the payout amount display field 11e on the game screen of the touch panel 11 to the calculated payout amount. The eight odds sections are represented by different colors, and each color corresponds to a roulette color described later.

When the bet acceptance is thus completed, the game progress control unit 101 outputs a card generation command to the card generation unit 102. Accordingly, the card generation unit 102 executes the arrangement determination program to generate two pieces of bingo card arrangement information, and stores the two pieces of generated arrangement information in the arrangement information storage area of the RAM 7. When the card generation unit 102 generates the array information, the game progress control unit 101 reads the two array information from the array information storage area of the RAM 7 and outputs a card display command based on the array information to the station display unit 103. As a result, two bingo card images composed of number images “1” to “25” randomly arranged in a 5 × 5 matrix are displayed on the touch panel 11 of the station 10 where the player has inserted medals. (S2).
In this embodiment, a case where two bingo card images are displayed on the touch panel 11 of one station 10 is described. However, one bingo card image is displayed, or three or more bingo card images are displayed. You may make it do.

  When the bingo card image is thus displayed on the touch panel 11 of the station 10, first to fourth lotteries are performed (S3). Specifically, the game progress control unit 101 outputs a first lottery start instruction to the lottery unit 105, and the lottery unit 105 wins each number determined by the winning probability data stored in the winning probability storage area of the RAM 7. A computer lottery is performed according to the probability, and a winning number is determined. An example of the lottery process performed by the lottery unit 105 will be described in detail. A predetermined random number is set so that each unsuccessful number that has not been won so far has a winning probability determined by winning probability data stored in the winning probability storage area of the RAM 7. Divide the range into categories that correspond to each winning number. Accordingly, in the first lottery, a classification corresponding to the numbers “1” to “25” is assigned to a predetermined random number range. In the second lottery, divisions corresponding to 24 unwinned numbers other than the numbers won in the first lottery among “1” to “25” are assigned to a predetermined random number range. Similarly, in the third lottery, a division corresponding to an unwinned number excluding a winning number won so far is assigned. If the winning probability is not changed by the winning probability changing process described later, the respective sections are assigned equally. Then, after dividing a predetermined random number range in this way, a random number is generated, a section to which the random number belongs is specified, and a number corresponding to the specified section is determined as a winning number. The determined winning number is stored in the winning history storage area of the RAM 7.

Further, the game progress control unit 101 outputs a roulette rotation command to the main display unit 104. As a result, the main display unit 104 rotates the roulette of the roulette image displayed on the large-sized display 2 and produces an effect that the lottery is being performed.
FIG. 8 is an explanatory diagram illustrating an example of a main screen displayed on the large display 2.
On the main screen, a roulette image having an image area corresponding to a number that has not been won among “1” to “25” is displayed. Accordingly, in the first lottery effect, roulette images having image areas corresponding to all numbers “1” to “25” are displayed, and in the second lottery effect, one of “1” to “25” is displayed. A roulette image having an image area corresponding to 24 numbers excluding the number won in the second lottery is displayed. In subsequent lottery effects, a roulette having an image area corresponding to a number excluding the winning number won so far. An image is displayed.

  Here, the difference in the size of the image area of each number in the roulette image on the large display 2 corresponds to the magnitude relationship of the winning probability of each number. If the winning probability is not changed by a winning probability changing process to be described later, the winning probability of each number is equal, and the size of the image area of each number in the roulette image is equal to each other. However, when the winning probability is changed by the winning probability changing process, as shown in FIG. 8, the numbered image area with a high winning probability is widened and the numbered image area with a low winning probability is narrowed.

  Further, the color of the image area of each number in the roulette image on the large display 2 corresponds to the payout amount of each number. That is, the color of the image area of each number corresponds to the colors of the eight odds categories in the payout 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 payout amount to be paid out when the number is won in the next lottery by seeing the color of each number in the roulette image on the large display 2 and thereby the bingo is completed. Can do.

  When the main display unit 104 receives the roulette rotation command, the main display unit 104 rotates the roulette of the roulette image displayed on the large display 2 and performs an effect that the lottery is being performed. Thereafter, the game progress control unit 101 reads the winning number stored in the winning history storage area of the RAM 7 and outputs an effect display command indicating that the winning number is won to the main display unit 104. Thereby, as shown in FIG. 8, the main display unit 104 performs an effect of causing the number image related to the winning number to appear in the central portion of the roulette image displayed on the large display 2. In the example shown in FIG. 8, “21” is the winning number. That is, the main display unit 104 functions as a notification unit that notifies the player of the winning number every time the lottery unit 105 determines the winning number.

  Further, the game progress control unit 101 that has read the winning number stored in the winning history storage area of the RAM 7 outputs a display command to the station display unit 103, and displays the winning history display field 11 d on the game screen of the touch panel 11. At the same time, the number image corresponding to the winning number in the bingo card image is changed from a round frame to a number surrounded by a square frame. That is, the station display unit 103 also functions as a notification unit that notifies the player of the winning number every time the lottery unit 105 determines the winning number.

  When the lottery effect as described above is repeated three more times and the lottery effect is performed up to the fourth time, the game progress control unit 101 outputs a determination command to the bingo determination unit 107. Thereby, the bingo determination part 107 performs the reach determination process mentioned above (S4). When it is determined that a reach has occurred in the reach determination process, the bingo determination unit 107 sends reach generation information to the game progress control unit 101, and the game progress control unit 101 sets a reach flag for the corresponding sequence information. Stand up (S5).

  Next, the game progress control unit 101 performs a winning probability changing process for the winning desired number that the player wishes to win (S20). This winning probability changing process is performed every time the fourth, sixth, eighth and tenth lotteries are completed. Details of the winning probability changing process will be described later.

Subsequently, the game progress control unit 101 performs the fifth lottery and determines the fifth winning number (S6). And the game progress control part 101 outputs a determination command to the bingo determination part 107, and makes the bingo determination part 107 perform the bingo determination process mentioned above (S7). In this bingo determination process, is a bingo generated from the winning number (currently five winning numbers) stored in the winning history storage area of the RAM 7 and the array information stored in the array information storing area of the RAM 7? Determine whether or not. When it is determined that bingo has occurred, the bingo determination unit 107 sends bingo generation information to the game progress control unit 101. In response to this, the game progress control unit 101 outputs to the medal management device 18 a payout command instructing the payout of the payout amount in the odds category corresponding to the winning number won in the fifth lottery. Upon receiving the payout command, the medal management device 18 temporarily stores the payout amount relating to the payout command, and performs processing for adding credits corresponding to the payout amount to the credit data when the bingo game is completed. (S8).
In addition, the bingo determination unit 107 that has received the determination command also performs the reach determination process described above (S9). If it is determined that the reach has occurred, a reach flag is set for the corresponding array information (S10).

  Thereafter, the game progress control unit 101 outputs an odds calculation command to the odds management unit 108. As a result, the odds management unit 108 updates the odds data of each number (S11). Specifically, odds data is calculated for each unwinned number that has not been won in the lottery so far. The calculated odds data is stored in the odds storage area of the RAM 7 in association with the corresponding winning number. In the present embodiment, when the fourth lottery is completed, the basic odds data of 30 times is selected for all 21 unwinned numbers. That is, the odds when bingo is established in the fifth lottery is 30 times. If the odds data is not changed in the winning probability changing process described later, the basic odds data that is one step lower than the current basic odds data is selected for each winning number when the lottery after the fifth round is completed. This is stored in the odds storage area of the RAM 7. Therefore, if the odds data is not changed in the winning probability changing process described later, 20 basic odds data that is 20 times lower than the current basic odds data of 30 times when the fifth lottery ends. All the unwinned numbers are uniformly selected, and the basic odds data that is one step lower is sequentially selected even after the subsequent lottery is completed.

  Here, the payout amount displayed in the payout amount display field 11e on the game screen on the touch panel 11 of the station 10 is updated when the fourth, sixth, eighth, and tenth lottery effects are completed. Until the three numbers on the same line on the bingo card image displayed on the game screen become the winning numbers, the payout amount corresponding to the basic odds data is displayed in the area corresponding to each color in the payout amount display column 11e. Is displayed. On the other hand, if three or four numbers on the same line are the winning numbers on the bingo card image when the payout amount display column 11e is updated, the actual odds are displayed in the area corresponding to each color in the payout amount display column 11e. A payout amount corresponding to the data is displayed. The actual odds data is calculated by the odds management unit 108 based on the probability that a bingo will be established in the subsequent two lotteries (the lottery performed until the payout amount display column 11e is updated next time). Specifically, the winning probability of each number at the time of updating (if the winning probability data is changed by the winning probability changing process described later, the winning probability after the change) and the touch panel 11 of the station 10 at the time of updating. It is calculated from the arrangement relationship of the numbers on the matrix array obtained from the array information corresponding to the bingo card image displayed on the screen. By performing such processing, in the touch panel 11 of the station 10 that displays the bingo card image in which three or four numbers on the same line are the winning numbers when the dividend amount display column 11e is updated, the dividend amount display column The payout amount displayed on 11e is changed from the payout amount based on the basic odds data to the payout amount based on the actual odds data. As a result, after three or four numbers on the same line become the winning numbers, the unique payout amounts are displayed on the payout amount display column 11e on the touch panel 11 of each station 10, respectively. That is, the number and color of each color-coded odds section on the payout amount display column 11e are common to all stations 10, but the payout amounts displayed in each odds section are different from each other.

  When the odds management unit 108 stores the odds data of each unsuccessful number in the odds storage area of the RAM 7 in this way, the game progress control unit 101 outputs a roulette change display command to the main display unit 104. Upon receiving this roulette change display instruction, the main display unit 104 has an image area of the current unsuccessful number (20 numbers at the end of the fifth lottery) on the large display 2 and the color of each image area. Displays a roulette image having a color corresponding to the odds data updated in S11 (S12).

  Then, the game progress control unit 101 determines whether the number of lotteries that have been completed so far is any one of the sixth, eighth, and tenth times (S13). If it is determined that it is the sixth, eighth, or tenth time, the winning probability changing process is executed (S20). That is, in this embodiment, the winning probability changing process is performed every time the fourth, sixth, eighth and tenth lotteries are completed. On the other hand, if it is determined that it is not any of the sixth, eighth, and tenth times, the game progress control unit 101 determines whether or not the number of lotteries that have been completed so far has reached 12 (S14). If it is determined that the number has not reached 12 times, the next lottery process is performed without executing the winning probability changing process (S6). On the other hand, if it is determined that the number has reached 12 times, the bingo game is terminated.

  When the bingo game ends in this way, the medal management device 18 performs a process of adding credits corresponding to the payout amount temporarily received in response to the payout command during the bingo game to the credit data. Thereby, the credit amount displayed in the credit display column 11c becomes the credit amount after addition.

Next, the winning probability changing process, which is a characteristic part of the present invention, will be described.
FIG. 9 is a flowchart showing the flow of the winning probability changing process.
In the present embodiment, when the fourth, sixth, eighth, and tenth lotteries are completed, the game progress control unit 101 prompts the station display unit 103 to touch the number that the player wishes to win. A display command for displaying a description image is output. As a result, the station display unit 103 displays an explanatory text image “Please touch the desired number” on the game screen of the touch panel 11, as shown in FIG. The player who sees the explanatory image selects one of the number images of the winning numbers in the bingo image displayed on the game screen of the touch panel 11 and touches the number within the time limit. Then, the winning desired number information indicating the touched number is output from the input control device 17, and the winning desired number information is received by the game progress control unit 101 (S21). Note that if the winning desired number information is not received within the time limit, the winning probability changing process is terminated as it is.

  When the game progress control unit 101 receives the winning wish number information, the game progress control unit 101 functions as a desired lottery object determination unit, and determines a winning wish number that is a desired lottery object that the player desires to win. Then, a winning probability changing command is output to the winning probability changing unit 106. Thereby, the winning probability changing unit 106 functions as winning probability data changing means, and winning probability data stored in the winning probability storage area of the RAM 7 so that the winning probability of the winning desired number related to the winning probability changing command is increased. Is changed (S22). Due to this change, in the lottery process by the lottery unit 105, the division corresponding to the winning desired number in a predetermined random number range is widened, and the remaining unwinned numbers are uniformly narrowed. Therefore, the winning probability of the winning desired number increases.

  Here, in this embodiment, a maximum of seven players can participate in the bingo game at the same time. Therefore, there may be cases where different winning number information is received from each of the input control devices 17 of the plurality of stations 10. Even in this case, the game progress control unit 101 outputs a winning probability change command for each winning desired number information. Thereby, the winning probability changing unit 106 changes the winning probability data stored in the winning probability storage area of the RAM 7 so that the winning probability of the winning desired number related to each winning probability changing command is increased. As a result, in the lottery process by the lottery unit 105, the divisions corresponding to the respective winning desired numbers in a predetermined random number range are expanded, and the remaining unwinned number divisions are uniformly narrowed. Therefore, the winning probability increases as the number of winning wishes received increases. However, when winning number information is received by multiple players, if the winning number information of many players is concentrated on one number, the winning probability of the other numbers will be even if winning number information on other numbers is received. Sometimes it goes down.

  Further, the game progress control unit 101 outputs an odds calculation command to the odds management unit 108. As a result, the odds management unit 108 reads the winning probability data changed in S22 from the winning probability storage area of the RAM 7 and changes the odds data in the odds storage area of the RAM 7 based on the winning probability data. (S23). Specifically, the odds data assigned to each winning number is changed so that the payout rate is substantially constant before and after changing the winning probability data in S22. Therefore, the odds data of each winning number is changed so that the odds data of the winning number whose winning probability is increased by the change of the winning probability data in S22 is relatively low.

  Subsequently, the game progress control unit 101 functions as a winning probability display control unit, and the size of the image area of each unwinned number in the roulette image corresponds to the winning probability after the change based on the winning probability data after the change. The roulette change display command is output to the main display unit 104 so that the color of the image area of each unsuccessful number becomes a color corresponding to the changed odds data. Thereby, the main display unit 104 functions as a winning probability image display means and a payout amount image display means, and the size of the image area of each unsuccessful number is a size corresponding to the winning probability after the change, and The roulette image in which the color of the image area of each unsuccessful number is a color corresponding to the changed odds data is displayed on the large display 2 (S24).

By performing the winning probability changing process as described above, the player sees the bingo card image displayed on the touch panel 11 and confirms the winning number up to the present time. By touching the image of the winning number desired to be won, the winning probability of the winning desired number can be increased.
In the present embodiment, the winning probability of each number can be grasped based on the size of the image area of the roulette image. Then, when the winning probability of the winning desired number is increased by touching the winning desired number image on the touch panel 11 that the player desires to win, the size of the image area of the winning desired number on the roulette image is increased accordingly. . Therefore, the player can intuitively grasp that the winning probability of the number that he / she wishes to win increases. At the same time, since the color of the image area of the desired number for winning on the roulette image changes to a color corresponding to the changed odds data, the player can intuitively grasp the changed payout amount.

  Further, in the present embodiment, every time the winning number desired by the player wins, the attack gauge in the attack gauge display field 11f displayed at the upper left of the game screen of the touch panel 11 increases, and this attack gauge Attack operation becomes possible when becomes full. Specifically, when the attack gauge is full, the player touches the winning desired number image on the touch panel 11 during the winning probability changing process and then presses the attack button 12 (attack operation), each time the winning desired number Information is received by the game progress control unit 101. That is, during one winning probability change process, a plurality of winning desired number information for the same number is received from the single station 10 by the game progress control unit 101. Thus, the player who can perform the attack operation can greatly increase the winning probability of the winning desired number that he / she wishes to win by pressing the attack button 12 during the winning probability changing process. However, in addition to the condition that the attack gauge is full, a condition for performing such an attack operation may be added. For example, a condition that a reach flag is set for 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 fourth, sixth, eighth, and tenth lotteries are finished, when the player touches the desired number on the touch panel 11, the desired number information is output from the input control device 17. Is received by the game progress control unit 101, and the winning probability of the winning desired number increases. The winning probability after the change is maintained until the next winning probability changing process is performed, but is reset when the next winning probability changing process is performed. That is, for example, when the winning probability of the desired number is increased at the end of the fourth lottery, the lottery is performed with the winning probability of the desired number being high in the fifth and sixth lotteries. At the end of the lottery, the winning probabilities for all unwinned numbers are reset uniformly. The same applies to the case where the winning probability of the winning desired number is increased at the end of the sixth, eighth and tenth lotteries.

FIG. 10 is a flowchart showing the flow of the attack process.
This attack process starts after the end of each lottery for the fourth and subsequent times. When the winning number with the winning probability being increased is won by lottery (S31), the game progress control unit 101 performs a process of increasing the attack gauge data stored in the attack gauge storage area of the RAM 7 by a predetermined amount. Perform (S32). In addition, the game progress control unit 101 outputs a display command to the station display unit 103 to increase the attack gauge in the attack gauge display field 11 f on the game screen of the touch panel 11.

  Thereafter, at the end of the fourth, sixth, eighth, and tenth lottery, that is, when the start condition of the winning probability changing process is satisfied (S33), the game progress control unit 101 stores the attack gauge in the RAM 7. It is determined whether or not the attack gauge data stored in the area has reached a specified amount (full tank) (S34). If it is determined that the tank is not full, the winning probability of the winning desired number can be increased by the normal winning probability changing process described above (S20). On the other hand, if it is determined that the tank is full, the game progress control unit 101 permits an attack operation at the corresponding station 10 (S35). Specifically, the game progress control unit 101 issues a display command to the station display unit 103 to display a description image that prompts the player to touch the number that the player wishes to win and then press the attack button 12. Output. As a result, the station display unit 103 displays an explanatory image to that effect on the game screen of the touch panel 11. The player who sees this explanatory image selects one of the number images of the winning numbers in the bingo image displayed on the game screen of the touch panel 11 and touches the number within the time limit (S38). After that, the attack button 12 is pushed as much as desired (S36). Then, the winning desired number information indicating the touched number is output from the input control device 17 as many times as the number of times the attack button 12 is pressed (S37), and these winning desired number information is received by the game progress control unit 101.

  The game progress control unit 101 that has received the winning desired number information functions as a variation determining means, and the more the number of winning desired number information outputted, the more the winning desired number desired by the player who plays at the output source station. In accordance with a predetermined variation amount determination condition that the amount of increase in the winning probability of the winning is increased, the amount of increase in the winning probability of the winning desired number is determined, and the winning probability changing unit 106 wins the winning desired number by the amount of the increasing amount The winning probability data is changed so that the probability increases. In this embodiment, only one winning desired number information can be output from one station 10 in the normal winning probability changing process. However, if an attack operation is performed, a plurality of winning desired number information for the same winning desired number is obtained from one station 10. Can be output. Therefore, 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, pressing the attack button 12 during the attack process only increases the winning probability of the desired number, but an additional bet may be made when the attack button 12 is pressed. A flowchart in this case is shown in FIG.
As shown in FIG. 11, when the player presses the attack button 12 during the attack process (S36), the desired winning number information is output (S37), and an additional bet signal is also output (S39). This additional bet signal is sent to the game progress control unit 101, which functions as a bet receiving unit, receives a bet, and outputs a bet command to the medal management device 18. Thereby, the medal management device 18 performs a process of subtracting a predetermined number (for example, one) of credits from the credit data and adding the credits to the bet data. In other words, in this example, the game progress control unit 101 functions as a variation determining means, and the more credits received for betting, the more the winning probability of the winning request number desired by the player who plays at the output source station is increased. In accordance with a predetermined variation amount determination condition of increasing, the amount of increase in the winning probability of the winning desired number is determined, so that the winning probability changing unit 106 increases the winning probability of the winning desired number by the amount of increase. Change winning probability data.

  Generally, the greater the amount of credits bet, the higher the risk of losing credits. According to this example, the higher the winning probability of the winning desired number, the higher the risk of losing credit. Therefore, a better game balance can be obtained as compared with the case where the winning probability of the winning desired number is simply increased.

  The attack operation described above can be performed when the fourth, sixth, eighth, and tenth lotteries are completed, but a bingo card image is displayed on the touch panel 11 of the station 10. May be performed before the winning number determined in the first lottery is notified. Even before the first winning number is notified, the player who has seen the bingo card image may wish to win the number placed at a position advantageous for bingo establishment or at his / her favorite position. is there.

In the example shown in FIG. 11, a player who has a large amount of additional bets wishes to win, so that the winning probability increases. However, a player who has a large bet at the start of the bingo game wins You may make it the winning probability increase, so that the winning wish number which desires. A flowchart in this case is shown in FIG.
As shown in FIG. 12, when the game progress control unit 101 receives the winning desired number information (S 21), the game progress control unit 101 functions as a variation determining means and credits betted at the station 10 that is the source of the winning desired number information. The amount of increase in the winning probability of the desired number is determined according to a predetermined variation amount determining condition that the amount of increase in the winning probability of the winning number becomes larger as the amount increases (S25). Specifically, the game progress control unit 101 that has received the winning desired number information acquires the credit amount betted at the station 10 that is the transmission source of the winning desired number information from the medal management device 18. Based on the credit amount, the increase amount of the winning probability is determined so that the winning probability of the winning desired number increases as the credit amount increases. When the game progress control unit 101 outputs a winning probability change command to the winning probability changing unit 106, the winning probability changing unit 106 increases the winning probability of the winning desired number by the amount of increase related to the winning probability changing command. Thus, the winning probability data stored in the winning probability storage area of the RAM 7 is changed (S22).

  In the example shown in FIG. 12, the degree to which the winning probability can be increased by one winning desired number information varies depending on the credit amount bet on the station 10 that is the source of the winning desired number information. That is, the player who has a higher risk of losing credit can increase the winning probability of the winning wish number. Therefore, a better game balance can be obtained as compared with the case of merely increasing the winning probability of the winning desired number.

Next, another example in which the degree to which the winning probability can be increased by one winning request number information will be described.
FIG. 13 is a flowchart showing the flow of the winning probability changing process according to this example.
When the game progress control unit 101 receives the winning desired number information (S21), it determines whether or not a reach flag is set for the array information corresponding to the station 10 that is the source of the winning desired number information (S26). When the reach flag is not set, the game progress control unit 101 functions as a fluctuation amount determining means, and determines the increase amount of the winning probability of the winning desired number as a small increase amount (S27). On the other hand, when the reach flag is set, the game progress control unit 101 functions as a change amount determination means, and determines the increase amount of the winning probability of the winning desired number as a large increase amount (S28). That is, the game progress control unit 101 determines the winning probability of the desired winning number according to a predetermined variation amount determination condition that the winning amount of the winning desired number is different in the reach state and not in the reach state. Determine the amount of increase. After that, when the game progress control unit 101 outputs a winning probability changing command to the winning probability changing unit 106, the winning probability changing unit 106 increases the winning probability of the winning desired number by the amount of increase related to the winning probability changing command. Thus, the winning probability data stored in the winning probability storage area of the RAM 7 is changed (S22).

  In the example shown in FIG. 13, the degree to which the winning probability can be increased by one winning desired number information depends on whether or not the reach flag is set for the arrangement information corresponding to the station 10 that is the source of the winning desired number information. change. Specifically, the player who reaches reach can increase the winning probability of the desired number. Accordingly, the player's superiority or inferiority in the winning probability of the winning desired number is different between when the player is in the reach state and when the player is not in the reach state.

In the above description, the case where the present invention is applied to a bingo game machine which is a medal game machine as a game machine for business use has been described as an example. However, not only a bingo game machine but also a computer lottery using a computer lottery. The present invention can be similarly applied to other game apparatuses such as game machines and coin game machines, or apparatuses using computer lotteries other than game apparatuses.
In the above description, the case where the winning probability of the winning desired number that the player wishes to win is changed as an example, but the winning probability of the winning desired number that the player desires to lose is changed. Also good.
In the above description, a multi-participant game device in which up to seven players can participate at the same time has been described as an example, but the same applies to a game device that is played by only one player.
It is also possible to connect a plurality of bingo game machines described above via a network and perform a bingo game using the same lottery result with a plurality of bingo game machines. In this case, the winning probability of the unsuccessful number is changed based on the winning desired number information by seven or more players, and the game performance is further improved by changing the winning probability.

A part of the configuration of the bingo game machine described above may be provided in a communication terminal such as a telephone having a data communication function held by the player. In this case, the bingo game machine needs to be provided with a communication means for performing data communication with the communication terminal via the network.
If a specific example is given, the example which displays the roulette image (winning probability image) displayed on the large sized display 2 mentioned above on the display means of the said communication terminal will be given. In this example, data for displaying the roulette image on the display means of the communication terminal is transmitted from the communication means to the communication terminal via the network. Then, when the winning probability changing unit 106 changes the winning probability data, the data for changing the roulette image displayed on the display means of the communication terminal to the one according to the changed winning probability data is the communication. The data is transmitted from the means to the communication terminal via the network. Thereby, the player can confirm the roulette image by looking at the display means of the communication terminal held by the player without looking at the large display 2. If all the images displayed on the large display 2 are displayed on the display means of the communication terminal, there is no need to provide the large display 2.
As another specific example, there is an example in which the player performs an operation of selecting a number desired to be won using the operation means of the communication terminal instead of the touch panel 11 of the station 10. In this example, for example, when the player operates the operation means of the communication terminal and selects the number that he / she wishes to win, the desired number information is transmitted from the communication terminal. When the communication means receives the winning desired number information, the game progress control unit 101 determines the winning desired number that the player desires to win based on the received winning desired number information.
As another specific example, there is an example in which the communication terminal is provided with the entire configuration of the station 10. In this case, the player can play using the communication terminal held by the player without using the station 10. However, in this case, it is difficult to provide the communication terminal with the medal delivery mechanism such as the medal insertion slot 13 and the medal receiving slot 14, so that a bet or payout is made using credit data without using a medal. To do.
