Description

  The present invention relates to a game device for consuming a game medium inserted by a player to advance a game, and providing the player with a game medium according to the progress of the game, and a game program for realizing the game device. , Relating to the lottery method.

  2. Description of the Related Art Conventionally, there has been known a game apparatus in which a player plays a game by inserting a medal as a play medium into a predetermined game field, and pays out a medal into the game field according to the progress of the game. In these game apparatuses, generally, the game proceeds according to the physical movement of the inserted medal. In addition, an electronic game, a lottery device, and the like are incorporated in the game device, and a game device combined with a game according to the physical movement of medals has been developed. Furthermore, a game device has been developed that uses an image displayed on the screen of the image display device instead of the physical structure of the game field.

  For example, a game apparatus has been developed in which a projectile is displayed on the screen when a player inserts a medal and a lottery is performed when the projectile hits an object on the screen (see Patent Document 1). . In this game apparatus, when a projectile hits an object on the screen, a slot image is displayed, and medals are paid out in accordance with how the stopped numbers are aligned (combination).

JP 2007-98032 A

  However, since the game apparatus performs lottery after determining that the projectile has hit an object on the screen, it takes time to perform lottery processing after the hit. The time for the lottery process after the hit is not a problem if the progressed game is a game that enjoys the lottery process, but when the progressed game is a game that requires a sense of speed like a so-called shooting game, There is a disadvantage that the speed of the game is impaired.

  In addition, when the medal payout is determined by lottery when the projectile hits an object on the screen, there is a problem that the payout rate depends on the skill of the player hitting the projectile against the object. The “payout rate” is a ratio of the total number of medals paid out in the same period to the total number of medals inserted in a certain period. For example, when the skill of the player is high, the number of lotteries is increased, so that the number of medals to be paid out increases. As a result, the payout rate increases. On the contrary, when the skill of the player is low, the number of lotteries is reduced, so that the number of medals to be paid out is also reduced. As a result, the payout rate decreases.

  The present invention has been conceived under the circumstances described above, and an object of the present invention is to provide a game device capable of suppressing the loss of the speed of the game due to the lottery process. Another object of the present invention is to provide a game device that can adjust the payout rate regardless of the skill of the player.

  In order to solve the above problems, the present invention takes the following technical means.

The game device provided by the first aspect of the present invention is progressed by consuming the game medium inserted by the player, and displays the progress of the game in which the game medium is given to the player according to the progress. Selection means for selecting and setting a point set for a predetermined game result by lottery before the predetermined game result is generated, an image display means for performing a predetermined operation by the player And an operation determining means for determining whether or not the predetermined game result has occurred as a result of the player performing the predetermined operation, and the operation determining means has determined that the predetermined game result has been generated. case, the up the game medium corresponding to the points set to the predetermined game result and benefits adding means for adding to the player, in the upper Symbol game progress Consumption count means for counting the game media consumed by the ear, grant count means for counting the play media given to the player during the game, the number counted by the consumption count means, and the grant count means Bei the payout value calculation means, and determination means for the payout value calculated by the payout value calculating means determines greater or not than a preset payout target value from counted the number is calculated the payout value The selecting means sets a point larger than the point selected by the lottery when the payout value when the point is selected by the lottery is determined to be less than or equal to the payout target value by the determining means, or The payout value is determined by the determining means. Serial and sets a smaller point than the selected point by drawing when it is determined to be larger than the payout target value.

  The “privilege” in the present invention is given to the player according to the progress of the game and includes, for example, medals, coins, balls, money, points (points), items, and the like.

  It should be noted that the “play medium” in the present invention is one that is inserted into the slot of the game device for the player to play a game, such as a medal, a coin, or a ball. Further, in the case of a system in which a game device reads a card that records the number of medals, coins, balls, etc. and recognizes that these cards have been inserted, reading the card is considered to insert game media. “Consuming game media” not only reduces the number of physical game media that have been inserted and stored, but also records the number of game media that have been inserted as the number of credits. Including reduction. That is, the value medium set only on the game space is also included in the game medium. Similarly, “giving game media” includes not only increasing the number of physical game media stored but also increasing the number of credits. If there is no mechanism for storing game media, the input of game media is the consumption of game media, and the payout of game media is the grant of game media. In a pusher-type medal game device or the like, the payout of medals or the like to the game field of the player is also included in “giving a play medium”. Also, if you put money in the slot and pay it out with medals after the game is over, it is considered that you have inserted money into the slot and purchased medals, etc. It is considered to be a “play medium”.

  The “payout value” in the present invention is an index for indicating the number of game media given to the player relative to the number of game media consumed by the player while the game is in progress. The payout rate obtained by dividing the number of media by the number of game media consumed by the player, the number of payouts obtained by subtracting the number of game media provided to the player by the number of game media consumed by the player, and the like.

  According to the present invention, a point to be set for a predetermined game result is selected and set before the predetermined game result is generated. Therefore, it is not necessary to select a point to be set for the predetermined game result after it is determined that the predetermined game result has occurred. Thereby, since the time for the selection process after generation | occurrence | production of a game result is not required, it can suppress that the sense of speed of a game is impaired.

  In addition, when the lottery is performed with the contents advantageous to the player as the payout value when the points are selected by the lottery is decreased, the case where the points set in the predetermined game result are increased. As a result, the number of game media provided when a predetermined game result is generated increases, and the payout value increases. That is, the payout value is adjusted to increase as the payout value decreases. Therefore, the payout value can be adjusted during the game regardless of the skill of the player.

  Other features and advantages of the present invention will become more apparent from the detailed description given below with reference to the accompanying drawings.

It is a figure for demonstrating an example of a probability table.

  Hereinafter, a preferred embodiment of the present invention will be specifically described with reference to the accompanying drawings, taking as an example a case where a shooting game proceeds in a so-called medal game device.

  The medal game device according to the present embodiment consumes medals as play media inserted by the player to advance the game, and grants medals to the player according to the progress of the game. In addition, the shooting game according to the present embodiment is a game in which a player character is operated in a virtual game space to hit an enemy character (hereinafter referred to as “enemy character”) and hit a fireball. In the game, medals are consumed every time the player character fires a fireball, and when the fireball that is fired hits an enemy character, medals of the number of medals set for the enemy character are awarded. In this case, “a fireball hits an enemy character” corresponds to the “predetermined game result” of the present invention, and “the number of medals set for the enemy character” is the “predetermined game result” of the present invention. Corresponds to “Point to be set”.

  The number of medals set for the enemy character is determined by lottery when the enemy character is generated in the virtual game space. A plurality of types of enemy characters are generated, and a probability table for lottery is set for each enemy character. A winning probability for each number of medals in the lottery is set in the probability table, and a lottery corresponding to the probability table is performed to determine the number of medals set for the enemy character. Details of the enemy character generation process and the probability table will be described later.

  In the shooting game according to the present embodiment, the cumulative number of medals consumed during the game (hereinafter referred to as “consumed medal cumulative number”) and the cumulative number of medals awarded (hereinafter referred to as “accumulated medal cumulative number”). "Number")). If necessary, the payout number PO is calculated by subtracting the accumulated medal number from the accumulated medal number. The payout number PO is an index for indicating the number of awarded medal cumulative numbers relative to the consumed medal cumulative number, as in the so-called payout rate. The “number of payouts” corresponds to the “payout value” of the present invention. In this game, adjustments are made in real time so that the number of payouts PO during the game is within the target range. That is, three probability tables, a high table, a medium table, and a low table, are set as probability tables, and the payout number PO is changed by changing the probability table to be used according to the payout number PO when the enemy character is generated. I have control.

  The low table is a probability table that is disadvantageous for the player, in which the winning probability of a large number of medals is low and the winning probability of a small number of medals is high compared to the middle table. On the other hand, the high table is a probability table advantageous to the player, in which the winning probability of a large number of medals is high and the winning probability of a small number of medals is low compared to the middle table. When the payout number PO is within the target range, for example, 0 <PO ≦ 100, the number of medals set for the enemy character is determined by lottery using the middle table. When the payout number PO is smaller than the target range, for example, when PO ≦ 0, the number of medals to be set for the enemy character is determined by lottery using a high table. In this case, the probability that a large number of medals is set is increased as compared with the case where the middle table is used. Therefore, the number of medals awarded at the time of hitting increases and the payout number PO increases. On the other hand, if the payout number PO is larger than the target range, for example, 100 <PO, the number of medals set for the enemy character is determined by lottery using a low table. In this case, since the probability that a large number of medals is set is reduced as compared with the case where the middle table is used, the number of medals awarded at the time of hitting is reduced and the payout number PO is reduced. In the present embodiment, the target range of the number of payouts PO is 0 <PO ≦ 100. However, the present invention is not limited to this. The target range of the payout number PO may be set as appropriate depending on the content of the game, or may be set differently for each medal game device.

  Next, a hardware configuration of the medal game device according to the present embodiment will be described.

  The image display unit 3 is composed of a relatively large liquid crystal display panel, for example, and has a screen 30 disposed horizontally above the housing 1. The screen 30 displays a game image of the slot game for each of the areas divided into four so as to correspond to the plurality of operation units 4. That is, the slot game is executed as a so-called video slot. Note that the image display unit 3 can display not only a slot game but also a game image such as a shooting game on the screen 30.

  As shown in FIG. 2, each operation unit 4 is provided with a medal insertion port 40, a medal insertion sensor 41 (not shown in FIG. 2), a bet button 42, a start button 43, a payout button 44, and an operation lever 45. It has been.

  A medal is inserted into the medal slot 40 by the player. The inserted medals are stored in a medal storage unit (not shown) inside the housing 1.

  The medal insertion sensor 41 is arranged on a path from the medal insertion slot 40 to the medal storage unit, detects the inserted medal, and outputs a signal to that effect to the CPU 10 described later. The number of medals inserted into the medal insertion slot 40 (hereinafter referred to as “medal insertion number”) is processed by the CPU 10 as the number of credits (the number of game play rights). The number of medals awarded according to the game result (hereinafter referred to as “medal awarded number”) is added to the number of credits.

  The bet button 42 is used when the player instructs a desired medal bet number in the slot game. For example, if the bet button 42 is pressed once, twice, or three times and operated, the number of medal bets becomes 1, 2, and 3 according to the number of button operations. The bet button 42 outputs an operation signal to the CPU 10 described later based on a pressing operation by the player. The CPU 10 counts the number of medal bets by counting the input operation signals. The bet button 42 is used as a firing button for firing a fireball in a shooting game.

  The start button 43 is used for the player to instruct the start of a slot game (start of display of a game image such that a plurality of reels rotate). In the shooting game, the start button 43 is also used as a firing button for firing a fireball.

  The payout button 44 is used for the player to instruct the payout of medals. When the player depresses the payout button 44, a number of medals corresponding to the number of credits are sent from the medal storage unit to the medal payout exit 1A via a medal transport mechanism (not shown) and are paid out from the medal payout exit 1A. Hereinafter, the number of medals to be paid out when the payout button 44 is pressed is referred to as “medal payout number”.

  The operation lever 45 is not used in the slot game, but is used as an operation lever for moving the player character in the shooting game.

  When the four operation units 4 are individually indicated, they are described as the operation unit 4a, the operation unit 4b, the operation unit 4c, and the operation unit 4d, and each of the screens 30 corresponding to the operation units 4a, 4b, 4c, and 4d. The regions are described as a screen 30a, a screen 30b, a screen 30c, and a screen 30d, respectively (see FIG. 2). Further, when the operation unit 4a and the screen 30a are considered as one game device in a pseudo manner, this is described as a satellite a. Similarly, a pseudo game device including the operation unit 4b and the screen 30b is described as satellite b, a pseudo game device including the operation unit 4c and the screen 30c is described as satellite c, and the operation unit 4d and the screen A pseudo game device including 30d is referred to as satellite d.

  As shown in FIG. 3, the medal game device A includes a CPU 10, a ROM 11, a RAM 12, a GPU 13, a VRAM 14, a video interface 15, an input interface 16, and an output interface 17 as hardware provided on the control board. The CPU 10, ROM 11, RAM 12, GPU 13, input interface 16, and output interface 17 are connected to each other via a bus 18. The image display unit 3 is connected to the GPU 13 via the VRAM 14 and the video interface 15. To the input interface 16, a medal insertion sensor 41, a bet button 42, a start button 43, a payout button 44, and an operation lever 45 are connected. The output interface 17 is connected to the speaker 5 and the electrical decoration 6.

  The CPU 10 executes a system program and a game program stored in the ROM 11 and performs various input / output controls and arithmetic processes. For example, the CPU 10 functions as a digital counter and performs a counting process for the number of credits, the number of medals inserted, the number of medals awarded, the number of medals bet, and the number of medals paid out. The CPU 10 calculates the number of credits using the number of medals inserted and the number of medals given as an added value, and the number of medals bet as a subtracted value. The CPU 10 executes a game program of a slot game or a shooting game, and sends a command to the GPU 13 to display a game image on the image display unit 3. As the slot game progresses, the CPU 10 functions as a random number generator and executes a predetermined lottery process. Further, the CPU 10 executes a lottery process when determining the number of medals set for the enemy character in the shooting game. CPU10 operates the speaker 5 and the electrical decoration 6 according to the progress situation of a slot game or a shooting game. The game image of the shooting game and the lottery process will be described later.

  The ROM 11 is a read-only semiconductor memory. The ROM 11 stores a system program for controlling basic operations of the hardware, a game program in which instructions and procedures for causing the CPU 10 to execute various processes relating to the game are stored. The ROM 11 stores game images of slot games and shooting games, a lottery table used when the CPU 10 performs a predetermined lottery process, and the like.

  The system program includes a program for causing the CPU 10 to function as a digital counter. The game program includes a program that describes the progress procedure of the slot game and the shooting game, and also includes a program for causing the CPU 10 to function as a random number generator. The game image includes a plurality of patterns, character images, an effect image for notification, a background image, and the like constituting a slot game and a shooting game. A plurality of lottery tables are prepared according to a plurality of lottery processes. Note that the game program, the game image, and the lottery table may be recorded in a recording medium such as a hard disk, an optical disk, or a flash memory, and the CPU 10 may appropriately read out from the recording medium via a reading device.

  The RAM 12 is a readable / writable semiconductor memory, and is used for temporary storage of a program load and image data by the CPU 10. For example, the RAM 12 stores image data read from the ROM 11 and a lottery table.

  The GPU 13 performs high-speed calculation processing necessary for game image display processing. For example, the GPU 13 generates a game image at a frame rate of 20 fps, and transfers the generated image data frame by frame to the VRAM 14.

  The VRAM 14 is a semiconductor memory dedicated to video display. For example, the VRAM 14 functions as a frame buffer that temporarily holds a game image generated by the GPU 13. A game image is transmitted frame by frame from the VRAM 14 to the image display unit 3 via the video interface 15.

  In the present embodiment, the case where four satellites are controlled by one control board is described, but a control board may be provided for each satellite. In this case, the control boards are connected and synchronized with each other. Also, a control board for each satellite and a control board for controlling all the satellites may be provided.

  Next, the operation of the medal game device A will be described.

  FIG. 4 is a flowchart for explaining a main process for controlling the overall flow of the game, executed by the CPU 10 of the medal game apparatus A, for example. The main process is started when the power of the medal game apparatus A is turned on, and is executed for each satellite. Below, the main process performed with respect to the satellite a (satellite which consists of the operation part 4a and the screen 30a) is demonstrated.

  When the power of the medal game apparatus A is turned on, a demo image is displayed and a medal insertion waiting state is entered (S1). Since the main process is started for other satellites, the demo images are displayed in the respective areas of the screen 30 (screens 30a, 30b, 30c, and 30d).

  In step S2, it is determined whether or not a medal has been inserted (S2). The determination is performed based on a signal input from the medal insertion sensor 41 of the operation unit 4a. If it is determined that no medal is inserted (S2: NO), the process returns to step S1 and the display of the demo image is continued. That is, the display of the demo image is continued on the screen 30a until the insertion of a medal is detected.

  If it is determined in step S2 that a medal has been inserted (S2: YES), the start of a normal game control process (hereinafter referred to as “normal game process”) is instructed (S3). The normal game is a slot game, and the normal game process is executed in parallel in another process routine.

  FIG. 5 is a diagram showing a screen display of one scene while the normal game is in progress. In the figure, a state in which a normal game is being executed on all satellites a, b, c, and d is shown. On the screens 30a, 30b, 30c, and 30d, images of slot games for the players who operate the operation units 4a, 4b, 4c, and 4d are displayed, respectively. Since the operation units 4c and 4d are located on the upper side of the screen 30 in the figure, the images displayed on the screens 30c and 30d, which are images for the player who operates the operation units 4c and 4d, are upper and lower in the figure. It is an upside-down image. In the center of the screen 30, an image for use by all players in common is displayed.

  The normal game process includes, in addition to the progress process of the slot game as the normal game, a process such as a mini game that is started in accordance with a pattern arranged in the slot game. Note that the detailed description of the normal game process is omitted.

  Next, it is determined whether or not there is a satellite that satisfies a predetermined condition (S4). If it is determined that there is no satellite that satisfies the predetermined condition (S4: NO), the process returns to step S4. If it is determined that there is a satellite that satisfies the predetermined condition (S4: YES), the process proceeds to step S5. That is, the determination in step S4 is repeated until a predetermined condition is satisfied by any satellite. During this time, a normal game, a mini game, and the like are advanced by the normal game process. In the present embodiment, a predetermined condition is that all predetermined items are collected in a mini game that is started when a predetermined number of loses occur in a normal game (slot game). The predetermined condition is not limited to this, and may be determined as appropriate in the overall design of the game. For example, a predetermined condition may be that a predetermined pattern is prepared in a normal game (slot game) or that a predetermined time has elapsed for a normal game.

  In step S5, switching from the base game to the special game is instructed (S5). The special game is a roulette game or a shooting game, and a roulette game control process (hereinafter referred to as “roulette game process”) and a shooting game control process (hereinafter referred to as “shooting game process”) They are executed in parallel in different processing routines. Note that the roulette game process and the shooting game process are collectively referred to as a special game process. That is, in step S5, the stop of the normal game process is instructed, and the start of the special game process is instructed.

  In the satellite that satisfies the predetermined condition in step S4, the roulette game process is executed to advance the roulette game, and in the other satellites, the shooting game process is executed to advance the shooting game. The roulette game is a game as a reward for a player who satisfies the predetermined condition of step S4, and includes a winning of a super jackpot (hereinafter referred to as “SJP”) with a very large amount of medals. A detailed description of the roulette game process will be omitted. Further, the shooting game is a game for a player who plays with a satellite other than the satellite in which the roulette game proceeds. Details of the shooting game process will be described later.

  FIG. 6 is a diagram showing a screen display of one scene in progress of the special game. In the center of the screen 30a and the screen 30 shown in the figure, an image of a roulette game that is a special game for the player who operates the operation unit 4a is displayed. Further, on the screens 30b, 30c, and 30d shown in the figure, images of shooting games for the players who operate the operation units 4b, 4c, and 4d are displayed, respectively. That is, this figure is a case where the player of satellite a satisfies a predetermined condition.

  Next, it is determined whether or not the special game process is completed (S6). When it is determined that the special game process has not ended (S6: NO), the process returns to step S6, and the determination in step S6 is repeated. During this time, the special game is advanced by the special game process. On the other hand, if it is determined that the special game process has ended (S6: YES), the process proceeds to step S3. That is, the normal game process is started when the special game process is completed (S3). The roulette game process ends when the roulette game ends, and the shooting game process also ends when the roulette game ends. That is, when the roulette game ends, the special game processing for all the satellites ends all at once, and the normal game starts. Thereafter, steps S3 to S6 are repeated, and the normal game process and the special game process are repeated. The main process is ended when the power of the medal game device A is turned off.

  Next, details of the shooting game process will be described with reference to FIGS.

  FIG. 7 is a diagram showing a screen display of one scene of the shooting game that is progressed by the shooting game processing, and is an enlarged view of the screen 30b in FIG. 6 (note that the roulette displayed in the center of the screen 30). (Images are omitted.)

  The shooting game is a game in which a player character appearing in the virtual game space is operated to hit an enemy character generated in the virtual game space with a fireball to defeat it. In the figure, a player character PC riding on a lift is displayed at the center of the screen. The vertical movement of the lift and the direction of the player character PC are operated by the operation lever 45 of the operation unit 4. That is, the player can move the lift downward by tilting the operation lever 45 downward (frontward as viewed from the player), and can move the lift upward by tilting upward (direction away from the player). Can be made. Further, the player can turn the player character PC to the left by tilting the operation lever 45 to the left, and can turn the player character PC to the right by tilting to the right. The player can fire a fireball by pressing the bet button 42 or the start button 43.

  In the figure, an enemy character ECa and two enemy characters ECb are displayed. The player operates the operation lever 45 to change the position and orientation of the player character PC, presses the bet button 42 or the start button 43, fires a fireball, and hits the fireball to hit the enemy characters ECa, ECb. Can be defeated. Each time a fireball is fired (that is, every time the bet button 42 or the start button 43 is pressed), one medal is consumed. Further, when the fireball hits the enemy characters ECa and ECb, medals of the number of medals set for the enemy characters ECa and ECb are awarded. The number of medals set for each enemy character ECa, ECb is determined by lottery when the enemy characters ECa, ECb are generated. Note that the four dashed ellipses in the figure indicate the location where the enemy character appears and are not displayed on the actual screen display.

  FIG. 8 is a flowchart for explaining a shooting game process executed by, for example, the CPU 10 of the medal game apparatus A. The shooting game process is started after the normal game process is stopped in step S5 of the flowchart showing the main process in FIG. 4, and is executed for each satellite other than the satellite that satisfies the predetermined condition. Below, the shooting game process performed with respect to the satellite b (satellite which consists of the operation part 4b and the screen 30b) is demonstrated.

  First, the start of enemy character generation processing is instructed (S11). The enemy character generation process is a process executed in parallel in another process routine, and performs a process of generating an enemy character in the virtual game space. Details of the enemy character generation process will be described later.

  Next, it is determined whether or not an operation for moving the player character PC has been performed (S12). This determination is made based on whether or not an operation signal is input by operating the operation lever 45. When it is determined that the moving operation has been performed (S12: YES), a player character moving process is performed (S13), and the process proceeds to step S14. The player character moving process is a process of changing the direction of the player character PC or moving the player character PC and the lift up and down based on the input operation signal. If it is determined that the moving operation has not been performed (S12: NO), the process proceeds to step S14.

  In step S14, it is determined whether or not a fireball firing operation has been performed (S14). This determination is made based on whether or not an operation signal is input by pressing the bet button 42 or the start button 43. When it is determined that the firing operation has been performed (S14: YES), the firing process is performed (S15), and the process proceeds to step S16. The firing process is a process in which the player character PC performs an effect of firing a fireball. In the firing process, for example, an effect that a fireball is generated from the hand of the player character PC is performed, and an effect that the fireball flies by a fireball movement process described later is performed. The fireball launching production is not limited to this. In the firing process, the number of consumed medals (medal consumption number) 1 is subtracted from the credit number, and the cumulative number of consumed medals is increased by one. The total number of medals consumed is the total number of medals consumed during the shooting game in all satellites where the shooting game is in progress, and is counted for calculating the payout number PO. Note that the payout number PO is calculated when an enemy character is generated. When it is determined that the firing operation has not been performed (S14: NO), the process proceeds to step S16.

  In this embodiment, one medal is consumed every time one fireball is fired, but the present invention is not limited to this. For example, every time one fireball is fired, two medals may be consumed, or one medal may be consumed and two fireballs may be fired.

  In step S16, enemy character movement processing is performed (S16). The enemy character movement process is a process of moving the enemy characters generated by the enemy character generation process according to a predetermined algorithm. Next, a fireball moving process is performed (S17). The fireball moving process is a process of moving the fireball generated by the firing process in the traveling direction.

  Next, it is determined whether or not the fireball has hit the enemy character (S18). The determination is made, for example, by comparing the coordinate range of the fireball with the coordinate range of the enemy character and determining whether there is an overlapping portion. In addition, you may discriminate | determine whether it was hit or not using another method. If it is determined that a hit has occurred (S18: YES), a hit process is performed (S19), and the process returns to step S12. The hit process is a process of performing an effect in which a fireball hits an enemy character. In the hit process, for example, the enemy character that hit the fireball changes to a medal with the number of medals set, and the player character PC obtains the medal. The production at the time of hitting is not limited to this. In the hit process, the number of medals set for the enemy character hit by the fireball is given and added to the number of credits and the total number of awarded medals. The total number of awarded medals is the total number of medals awarded during the shooting game in all satellites where the shooting game is in progress, and is counted for calculating the payout number PO. Note that the payout number PO is calculated when an enemy character is generated. If it is determined that no hit has been made (S18: NO), the process returns to step S12.

  Thereafter, steps S12 to S18 are repeated. The shooting game process ends when the roulette game process ends. At this time, the cumulative number of consumed medals and the total number of awarded medals are reset and both are reset to zero. That is, the cumulative number of consumed medals and the total number of awarded medals are counted independently for each shooting game. Therefore, the payout number PO is independent for each shooting game (the payout number PO in the previous shooting game is not reflected). Note that the accumulated medals and the granted medals may be accumulated without being reset. In this case, the calculated payout number PO reflects the consumption and grant of medals in the previous shooting game. However, in order to demonstrate the effects of the present invention more effectively, every time the shooting game is finished (or the shooting game) so as to reflect only the consumption and grant of medals in the ongoing shooting game. It is desirable to reset the total number of consumed medals and the total number of granted medals (every time it is started).

  FIG. 9 is a flowchart for explaining enemy character generation processing executed by, for example, the CPU 10 of the medal game apparatus A. The enemy character generation process is executed for each satellite for which the start is instructed in step S11 of the flowchart showing the shooting game process of FIG. 8 and the shooting game process is being executed. Below, the enemy character generation process performed with respect to the satellite b (satellite which consists of the operation part 4b and the screen 30b) is demonstrated.

  First, an enemy generation pattern is determined by lottery (S21). The enemy generation pattern is a set of the type of enemy character to be generated and the timing for generation, and a plurality of patterns are set. Which enemy generation pattern is selected is determined by lottery.

  FIG. 10 is a time table for explaining an example of the enemy generation pattern.

  In the figure, the generation patterns of three types of enemy characters for 30 seconds are shown, the time from 0 to 30 seconds is shown on the horizontal axis, and the location of the time of the timing when the black circle in each enemy character column occurs Is shown in For example, in the pattern 1, the enemy character ECa is generated at the timing of 1, 11 and 21 seconds, the enemy character ECb is generated at the timing of 4, 6, 8, 14, 16, 18, 24, and 26 seconds, and 28 seconds. It is shown that the enemy character ECc is generated at the timing. In pattern 2, the enemy character ECa is generated at the timing of 1, 11, 21 seconds, the enemy character ECd is generated at the timing of 4, 6, 14, 16, 24, 26 seconds, and 8, 18, 28 seconds. It is shown that the enemy character ECe is generated at the timing. In the figure, a time table is shown so that the occurrence timing of the enemy character can be intuitively understood. However, a table that records the time of occurrence timing for each enemy character is actually recorded. It should be noted that the enemy generation pattern shown in the figure is merely an example, and the enemy generation pattern is not limited to the one showing the generation timing for 30 seconds. Further, the enemy generation patterns are not limited to those showing the generation patterns of three types of enemy characters, and the number of types of enemy characters may be different for each pattern.

  Next, the elapsed time from the enemy generation pattern determination and the generation timing of the enemy character in the determined enemy generation pattern are compared, and it is determined whether or not the enemy character generation timing has come (S22). If it is not the generation timing (S22: NO), the process returns to step S22. If the generation timing is reached (S22: YES), the process proceeds to step S23. That is, the determination in step S22 is repeated until the generation timing comes. For example, when the enemy generation pattern is determined to be the pattern 1 of FIG. 10 in S21, step S22 is repeated for 1 second after the determination, and the process proceeds to step S23 at the timing when it becomes 1 second.

  In step S23, the appearance position of the enemy character is determined by lottery (S23). The appearance position of the enemy character is determined as one of the positions indicated by the four dashed ellipses in FIG. In addition, the candidate of the appearance position of an enemy character is not restricted to this.

  Next, the number of medals set for the enemy character to be generated is determined by lottery (S24). Processing for determining the number of medals (hereinafter referred to as “set medal number lottery processing”) will be described later.

  Next, enemy character appearance processing is performed (S25). This process is a process for causing the enemy character that has been generated in step S22 to appear at the appearance position determined in step S23. The enemy character after the appearance is subjected to a movement process based on the enemy character movement process. Since the appearance location of the enemy character is behind the pillar at the position of the dashed ellipse shown in FIG. 7, it is not displayed on the screen when it appears, but is displayed on the screen when it comes out from the back side of the pillar by the enemy character movement process. (See the enemy character ECb at the upper left in FIG. 7).

  Next, it is determined whether or not the enemy generation pattern reproduction processing has been completed (S26). Specifically, it is determined whether or not 30 seconds have elapsed since the enemy occurrence pattern was determined in step S21. This is because the generation timing of the enemy generation pattern is set to 30 seconds. If the setting time of the enemy generation pattern is different from this, the elapsed time for determination is naturally different. If the enemy generation pattern reproduction process has not ended (S26: NO), the process returns to step S22 to wait for the next enemy character generation timing. On the other hand, when the enemy generation pattern reproduction process is completed (S26: YES), the process returns to step S21 to determine the next enemy generation pattern. The enemy character generation process is continued until the shooting game process is completed.

  FIG. 11 is a flowchart for explaining the set medal number lottery process executed by the CPU 10 of the medal game apparatus A, for example. The set medal number lottery process is a process executed in step S24 of the flowchart in the enemy character generation process shown in FIG. 9, and is executed every time an enemy character is generated.

  First, the payout number PO is calculated (S31). In the shooting game process shown in FIG. 8, the cumulative number of consumed medals and the total number of awarded medals are counted. For example, when a roulette game is progressing in satellite a, the cumulative value of the number of medals consumed and the total number of awarded medals during the shooting game in the satellite in which the shooting game is progressing among satellites b, c, and d. These are counted as the total number of consumed medals and the total number of granted medals, respectively. The payout number PO is calculated by subtracting the consumed medal accumulated number from the granted medal accumulated number. Note that the payout number PO is always calculated, and the calculated payout number PO may be referred to in step S31.

  Next, it is determined whether or not the payout number PO is greater than 100 (S32). When the payout number PO is larger than 100 (S32: YES), that is, when 100 <PO, a lottery using a low table (see FIG. 12) of the probability tables of the enemy characters to be generated is performed and set. The number of medals is determined (S33), and the set medal number lottery process is terminated.

  FIG. 12 is a diagram for explaining an example of the probability table.

  The probability table is set for each enemy character. In addition, a low table, a medium table, and a high table are set in each probability table, and a winning probability for each medal number in the lottery is set in each table. For example, in the probability table of the enemy character ECa shown in FIG. 5A, in the low table, the probability of loss (0 medal acquisition number; the same applies hereinafter) is 45%, the probability of one medal is 30%, and medal 2 The probability of 20 sheets and the probability of 3 medals are set to 5%. Similarly, in the middle table, the probability of loss is set to 25%, the probability of one medal is set to 30%, the probability of two medals is set to 25%, and the probability of three medals is set to 20%. The probability of loss is 15%, the probability of one medal is 20%, the probability of two medals is 35%, and the probability of three medals is 30%.

  The low table has a lower probability of winning two medals and three medals than the middle table, and has a higher probability of winning out of play. That is, the probability table is disadvantageous for the player. On the other hand, compared with the middle table, the high table has a higher probability of winning two medals and three medals, and a lower probability of winning out and one medal. That is, the probability table is advantageous for the player. The figure shows an example of a probability table, and the probability set in each table may be determined as appropriate in the overall design of the game. Further, FIG. 5A shows an example in which the number of medals set is 1 to 3, but the range of the number of medals set for each enemy character may be changed. For example, the probability table of the enemy character ECb shown in FIG. 5B is an example in the case where the number of medals set is 1 to 5.

  In step S32, when the payout number PO is 100 or less (S32: NO), it is determined whether or not the payout number PO is larger than 0 (S34). When the payout number PO is larger than 0 (S34: YES), that is, when 0 <PO ≦ 100, the number of medals set by lottery using the middle table of the probability tables of the enemy characters to be generated is set. It is determined (S35), and the set medal number lottery process is terminated. On the other hand, when the payout number PO is 0 or less (S34: NO), that is, when PO ≦ 0, the number of medals set by the lottery using the high table of the probability tables of the enemy characters to be generated is set. It is determined (S36), and the set medal number lottery process is terminated.

  According to the present embodiment, in the shooting game, when an enemy character is generated, a lottery is performed to determine the number of medals set for the enemy character. Therefore, there is no need to perform a lottery process when a fireball hits an enemy character. Thereby, since the time for the lottery process after the hit is not required, it is possible to suppress the sense of speed of the shooting game from being impaired.

  Further, according to the present embodiment, lottery of the number of medals set for the enemy character is performed by switching the probability table according to the payout number PO at that time. When the payout number PO is larger than the target range, a lottery is performed using a low table disadvantageous to the player. When the low table is used, the probability that a large number of medals is set for the enemy character is reduced and the probability that a small number of medals is set is increased as compared with the case where the medium table is used. Therefore, the number of medals awarded at the time of hitting is reduced and the payout number PO is adjusted to be small. On the other hand, when the payout number PO is smaller than the target range, a lottery is performed using a high table advantageous to the player. When the high table is used, the probability that a large number of medals is set for the enemy character is increased and the probability that a small number of medals is set is decreased as compared with the case where the medium table is used. Accordingly, the number of medals awarded at the time of hitting is increased and the payout number PO is increased. In this way, the payout number PO can be adjusted during the game regardless of the skill of the player.

  For example, in the case of the probability table of FIG. 12A, the average value of the number of medals determined by the lottery using the low table is 0.85 (= 1 × 30% + 2 × 20% + 3 × 5%). )become. Similarly, the average value in the case of the middle table is 1.4 (= 1 sheet × 30% + 2 sheets × 25% + 3 sheets × 20%), and the average value in the case of the high table is 1.8 sheets (= 1 sheet × 20% + 2 sheets × 35% + 3 sheets × 30%). Assuming that the probability that the player can hit the enemy character with a fireball is 70%, the average value of the number of medals awarded by the player by consuming one medal is 0.595 when the low table is used (= 0) .85 sheets x 70%), 0.98 sheets (= 1.4 sheets x 70%) when a medium table is used, 1.26 sheets (= 1.8 sheets x 70%) when a high table is used ) In other words, if the payout number PO is within the target range and the middle table is used, an average of about one medal is awarded for one medal consumption, so the payout number PO does not change much. Further, when the payout number PO is larger than the target range and a low table is used, about 0.6 medals are awarded on average for one medal consumption, so the payout number PO becomes small. On the other hand, when the payout number PO is smaller than the target range and a high table is used, about 1.3 medals are awarded on average for one medal consumption, and the payout number PO increases. Accordingly, the payout number PO is adjusted to be within a target range while the game is in progress.

  In the above embodiment, the case where the payout number PO obtained by subtracting the accumulated medal number from the total number of granted medals is described. However, the present invention is not limited to this. You may make it adjust the value regarding made payout. For example, a value obtained by dividing the total number of granted medals by the total number of consumed medals, that is, a so-called payout rate may be adjusted. In this case, for example, if the payout rate is greater than 1.1, 1.1 or less, greater than 1, and 1 or less, a low table, a medium table, and a high table may be used, respectively.

  In the above embodiment, the case where the lottery table is switched between the low table, the middle table, and the high table is described, but the present invention is not limited to this. The number of tables to be switched may be two, or four or more. Alternatively, the lottery table may be a single table and the number of medals may be adjusted after the lottery. For example, the number of medals obtained by subtracting 1 from the number of medals determined by lottery when PO> 100 (hereinafter referred to as “the number of winning medals”) is set, and the number of selected medals is 1 when PO ≦ 0. The number of added medals may be set. In addition, adjustment after table switching or lottery may not be performed. Even in this case, since the number of medals set for the enemy character is determined by lottery at the time of occurrence, there is no need to perform lottery processing at the time of hitting. Therefore, the time for the lottery process after the hitting is not required, and the effect that the feeling of speed is not impaired can be achieved.

  In the above embodiment, the probability table is set for each type of enemy character, but the present invention is not limited to this. For example, a common probability table may be applied to a plurality of enemy characters, or only one probability table common to all enemy characters may be set.

  In the above embodiment, a predetermined enemy character is generated at a predetermined timing according to the enemy generation pattern, but this is not a limitation. For example, without determining the type of enemy character in advance, the number of winning medals is determined according to the generation timing of the enemy generation pattern, and the type of enemy character generated according to the determined number of winning medals is determined. Also good. For example, the enemy character ECa may be generated when the number of winning medals is one, and the enemy character ECb may be generated when the number of winning medals is two. In this case, the player who has seen the generated enemy character can recognize how many medals can be obtained by defeating the enemy character.

  In the above embodiment, the game is described in which a medal is obtained by hitting an enemy character with a fireball. However, the present invention is not limited to this. For example, an object such as an enemy missile may be generated in place of the enemy character, or a medal may be obtained by the player's fighter dropping down instead of the player character.

  In the above embodiment, the case where the present invention is applied to a shooting game as a special game that is progressed while a player of a certain satellite is playing a roulette game has been described, but the present invention is not limited to this. The present invention can also be applied to a shooting game such as a mini game that is started in accordance with a pattern arranged in a slot game as a normal game. Further, the present invention may be applied to a shooting game as a normal game.

  A game to which the present invention can be applied is not limited to a shooting game, and the present invention can be applied to, for example, an action game or a fighting game. For example, the present invention can be applied to a game in which a player character is moved to pick up an item. In this case, when an item is generated on the game screen, the number of winning medals may be determined by lottery. In addition, when it is not possible to set the medal to be consumed every time the projectile is fired as in the shooting game, for example, the medal may be set to be consumed every predetermined time. In addition, when the present invention is applied to a fighting game, for example, a medal is consumed every time the player character is attacked, and a medal is given when the enemy character is damaged. The number of winning medals for each damage may be determined by lottery.

  In the above embodiment, the case where a plurality of players play a game with one game device has been described, but the present invention is not limited to this. Even when only one player plays a game on the game device, the present invention can be applied.

  In the above embodiment, the case where the payout number is calculated from the total number of consumed medals and the total number of awarded medals of all players who are playing a shooting game on the same game device has been described, but the present invention is not limited to this. For example, the cumulative number of consumed medals and the total number of awarded medals may be managed for each player, and the payout number may be calculated for each player. In this case, since the number of payouts can be adjusted for each player, in addition to the effects described above, there is an effect that the difficulty level of the game can be individually adjusted according to the skill of each player. That is, since the number of payouts of a player with high skill becomes large, the state where the low table is used becomes long, and the difficulty of the game becomes high. On the other hand, since the number of payouts of a player with a low skill becomes small, the state in which the high table is used becomes long and the difficulty of the game becomes low.

  Although the case where the present invention is applied to a so-called medal game device has been described in the above embodiment, the present invention is not limited to this. The present invention can also be applied to arcade game devices and home game devices in which medals or the like are not consumed or granted. For example, the present invention can be applied to a game played by betting a virtual value medium set in a game space in a mini game in a certain game. In addition, even in a game that does not involve a bet of value media, it is not necessary to determine the score to be set for the enemy character by lottery at the time of occurrence and to perform lottery processing at the time of hitting, so the sense of speed is not impaired. Can play.
