Description

The present invention relates to a game system in which the payout rate can be adjusted.

There is a well-known game system in which a player is made to play a game in exchange for consumption of game value, and a reward is given to the player according to the obtained result. In this type of game system, it may be necessary to adjust the payout rate of the reward to the player, that is, the ratio (or percentage) of the reward amount to the consumption amount of the game value by the player. For example, when a game system is operated for business or commercial purposes, it is necessary to adjust the payout rate so that the operating entity can secure an appropriate profit. On the other hand, in a game using a game medium such as a medal, the result of the game changes according to the skill of the game operation such as the player's operation of inserting the game medium. Therefore, it is desirable to set a certain relationship between the player's skill and the reward amount, such that the higher the player's skill (skill related to the game), the more reward is given. However, when the amount of reward is changed according to the skill, the problem is how to incorporate the adjustment of the payout rate. For example, if the player clearly feels that the control of the payout rate has intervened in the granting of the reward, there is an inconvenience that the interest of the game is reduced. As one solution to such a problem, when certain conditions are met in the game, a lottery is executed by a predetermined lottery mechanism, and the expected value of the reward obtained by the lottery is determined according to the situation of the payout rate. A system has been proposed in which the lottery process is used to control the payout rate (see, for example, Patent Document 1).

Japanese Unexamined Patent Publication No. 2011-36549

In a conventional game system, the lottery process is only executed as an opportunity to obtain an additional reward that occurs when the player obtains a predetermined result in the game, and the result is also unrelated to the skill of the player. .. Therefore, there is still room for consideration regarding the issue of incorporating the function of adjusting the payout rate into a game that includes the element of giving rewards according to skill.

Therefore, an object of the present invention is to provide a game system or the like capable of appropriately incorporating the adjustment of the payout rate for a game in which a reward is given according to a player's game operation.

The game system according to one aspect of the present invention includes a game operation receiving means that accepts a player's game operation in exchange for consumption of a predetermined game value, a game control means that calculates a game result according to the received game operation, and a game control means. A reward amount determining means for determining a reward amount to be given to the player based on the calculated game result, and a reward giving means for granting the determined amount of reward to the player are provided, and the reward is provided. The amount determining means is the game result so that the correspondence between the lottery means for executing the predetermined lottery when the predetermined lottery condition is satisfied and the game result and the reward amount given to the player is changed. It is further provided with a reward amount adjusting means for adjusting the reward amount to be determined based on the above according to the result of the lottery.

The computer program for a game system according to one aspect of the present invention corresponds to a game operation receiving means that accepts a player's game operation in exchange for consumption of a predetermined game value, and a received game operation. A game control means for calculating the game result, a reward amount determining means for determining the reward amount to be given to the player based on the calculated game result, and a reward for giving the determined amount of reward to the player. A lottery means that functions as a granting means and the reward amount determining means executes a predetermined lottery when a predetermined lottery condition is satisfied, and a correspondence relationship between the game result and the reward amount to be given to the player. It is configured to further function as a reward amount adjusting means for adjusting the reward amount to be determined based on the game result according to the result of the lottery so as to cause a change.

A game system according to another aspect of the present invention is connected to an input device for detecting a player's game operation, a storage device for storing a predetermined computer program, the input device, and the storage device, and is connected to the computer of the storage device. A game system including a processor that executes a predetermined process based on a program, wherein the processor operates a game of a player via the input device in exchange for consumption of a predetermined game value based on the computer program. Is accepted, the game result is calculated according to the accepted game operation, the amount of reward to be given to the player is determined based on the calculated game result, and the determined amount of reward is given to the player. In addition to granting, in determining the reward amount, a predetermined lottery is executed when a predetermined lottery condition is satisfied, so that the correspondence relationship between the game result and the reward amount to be given to the player changes.

FIG. 1 shows a main part of a game system according to an embodiment of the present invention. The game system 1 includes at least one game machine 2 (only one is shown in FIG. 1). The game machine 2 is installed in an amusement facility or the like where an unspecified number of public people enter and exit, and is operated for business or commercial purposes. This type of game machine is sometimes called an arcade game machine. The game machine 2 may be communicably connected to a predetermined game server 4 via a network 3 such as the Internet. The game server 4 includes at least one physical server computer device. The game server 4 may be configured as a server system in which a plurality of server computer devices are combined, or may be configured as a logical server system using cloud computing.

The game machine 2 includes a display device 5 for displaying a game screen, a plurality of stations 6 arranged so as to surround the outer periphery of the display device 5, and a center lottery mechanism 7 shared between the stations 6. .. As an example, one or a plurality of flat panel display devices are used for the display device 5. The display device 5 is installed on the game machine 2 so that the display surface thereof is horizontal and upward. Two stations 6 are provided for each side of the game machine 2, and eight stations 6 are provided for the entire game machine 2. Each station 6 is provided with an input device 8 that receives an input operation of a player related to the game. The input device 8 has an equal configuration among all stations 6. The input device 8 includes a detection unit 8a that detects a player's game operation. The detection unit 8a includes, as an example, an operation lever 9, a small button 10, and a large button 11. The operation lever 9 can be operated in the front-rear direction and the left-right direction with reference to a neutral position standing vertically upward when viewed from the player, and outputs an operation signal according to the operation direction. However, the operating lever 9 may be operable in any direction by 360 ° from the neutral position. Each of the small button 10 and the large button 11 outputs an operation signal corresponding to the pressing operation of the player. The large button 11 is larger than the small button 10, thereby visually differentiating the buttons 10 and 11.

Each station 6 is also provided with a reader 12 that reads a medium ID from a storage medium (not shown) such as a card owned by the player or a personal digital assistant. The medium ID is uniquely set for each storage medium. As the storage medium holding the medium ID, a magnetic storage medium, an IC chip, or various other non-volatile storage media may be used. In the game system 1, the medium ID is associated with a player ID unique to each player. The player ID is an example of player identification information that identifies a player. The game system 1 has a function of determining a player ID of a player based on a medium ID acquired via the reader 12 and thereby identifying the player. The player ID is used for player authentication, determination of play data associated with the player, and the like. The play data is data that records the play content of the player's game, and is used for the player to play the game from the continuation of the previous time. The configuration relating to the identification of the player and the storage of the play data may be the same as that of the known game system.

The center lottery mechanism 7 is supported by a pair of pillars 13 and beams 14 of the game machine 2 in a state of being suspended so as to be located above the center of the display surface of the display device 5. The center lottery mechanism 7 is, for example, a physical lottery mechanism that executes a lottery using a game medium such as a ball and gives a reward to the player according to the lottery result when a predetermined winning condition is satisfied in the game. It is provided as an example. For example, the center lottery mechanism 7 may be used when a jackpot lottery or the like that can obtain a large amount of reward occurs.

The game machine 2 further includes various devices such as a medal receiving device 15 that accepts medals as an example of a game medium, a payout exit 16 that pays out medals to a player, and a speaker device 17 that outputs a sound that directs a game. It is provided. The medal is used as an example of a game medium that symbolizes the game value. For example, one medal corresponds to one unit of game value. The game value is a value consumed when the player performs a predetermined game operation. The game value can be expressed quantitatively using appropriate terms. When the player expresses the game value that can be consumed in the game, the game value is quantitatively expressed by using the term "credit" as an example. In that case, one credit corresponds to one unit of game value. When a player inserts one medal into the game machine 2, the number of medals and the number of credits are associated with each other so that the player owns the game value of one credit. However, the credit is not limited to the example in which the credit is added by inserting a physical medal. By having the player purchase the game value in advance by a payment method using cash or virtual currency and storing the amount of the purchased game value in the play data, the player can store the game value held in the play data in the game. It may be possible to replace it with consumable credit. The medal slot 15a of the medal receiving device 15 is provided so as to be shared between two adjacent stations 6. The medal receiving device 15 is provided with a station selection switch 15b in order to indicate from which side the station 6 the medal has been inserted.

The game provided by the game machine 2 can be appropriately selected, but here, at least a part of the operations that the player should perform in the game is accepted in exchange for the consumption of a predetermined amount of game value (credit). The game is executed on the game machine 2. An example thereof will be described with reference to FIG. FIG. 2 shows an example of a game screen displayed on the display surface of the display device 5. The game screen 100 is displayed in each of the two areas obtained by bisecting the display surface of the display device 5 at the boundary line BL in FIG. That is, the game screen 100 of FIG. 2 is a game screen shared between the four stations 6. The game screen 100 is provided with a play area 101 and an information presentation area 102. The play area 101 is an area in which the progress of the game is displayed, and the information presentation area 102 is an area in which information to be presented to the player is displayed as the game progresses.

In the play area 101, a rectangular game field 110 divided in a grid pattern, player characters 111A to 111D, and a plurality of enemy characters 112 are displayed. The player characters 111A to 111D are associated one-to-one with each of the four stations 6 sharing the game screen 100. The player characters 111A to 111D move in the game field 110 according to the player's operation with respect to the input device 8 of the corresponding station 6. That is, the player characters 111A to 111D are examples of player objects that move in the game field 110 in response to a player's operation. The player characters 111A to 111D are displayed in a state in which they can be distinguished from each other by using shapes, colors, patterns and other visual elements. On the game screen 100, an indicator 113 for identifying the correspondence between the player characters 111A to 111D and the station 6 is displayed. As an example, the indicator 113 is displayed as a linear image connecting the position of the station 6 and the player characters 111A to 111D. However, the indicator 113 is not limited to a linear shape, and may be displayed in an appropriate manner as long as the player can identify the correspondence between the station 6 and the player characters 111A to 111D. In the following, the player characters 111A to 111D may be represented by reference numeral 111.

The player character 111 moves in the game field 110 according to the direction in which the player operates the operation lever 9. However, a plurality of blocks 114 and 115 are arranged in the game field 110. The location where the blocks 114 and 115 are arranged is set as a position where the player character 111 cannot move. Therefore, the player needs to advance the game while moving the player character 111 along the passage where the blocks 114 and 115 are not placed. The block 114 is fixedly arranged in the game field 110, and is provided as a fixed block in which changes such as movement and disappearance do not occur. On the other hand, the block 115 is provided as a variable block in which a change such as disappearance occurs according to a certain condition, such as when the player character 111 takes a certain action.

The behavior of the enemy character 112 is controlled by the computer of the game machine 2. That is, the enemy character 112 is an example of a so-called non-player character that cannot be operated by the player. The number, position, moving direction, etc. of the enemy characters 112 are appropriately controlled by the computer of the game machine 2. The enemy character 112 is set as a target of an attack by the player character 111. For example, as shown in FIG. 3A, the player character 111 can place an attack item 116 imitating a bomb or the like at an appropriate position in the game field 110 (excluding the positions of blocks 114 and 115). As shown in FIG. 3B, the attack item 116 exerts its effect when a predetermined effect generation condition is satisfied, such as a certain period of time elapses after its installation. The effect of the attack item 116 is, for example, a game in which an influence range 116a such as a blast is generated in a predetermined range centered on the installation location of the attack item 116, and the enemy character 112 existing in the influence range 116a is defeated. Set to get results. As one of the effects of the attack item 116, an effect such that the variable block 115 is destroyed may be set.

A plurality of types of attack items 116 are prepared according to the size of the influence range 116a. The player can install the attack item 116 having a relatively small influence range 116a by operating the small button 10, for example, and the attack item 116 having a relatively large influence range 116a by operating the large button 11. Can be installed. The magnitude of the influence range 116a can be regarded as the magnitude of the influence of the attack item 116 on the game result. In other words, the attack item 116 is provided with a plurality of types in which the value in the game (as an example, the influence on the game result) is differentiated. The position of the attack item 116 may be set according to, for example, the position of the player character 111. For example, when the player operates the operation lever 9 to move the player character 111 to an appropriate position and operates the button 10 or 11 at that position, the attack item 116 is installed at the position of the player character 111 at that time. To.

The operation of operating the small button 10 or the large button 11 to install the attack item 116 is set as a kind of game operation accepted in exchange for the consumption of a predetermined amount of game value by the player. The consumption amount of the game value is differentiated according to the effect of the attack item 116 so that the larger the effect (or value) of the attack item 116 is, the larger the consumption amount is. For example, when the small button 10 is operated to install the attack item 116, 1 credit is consumed, and when the large button 11 is operated to install the attack item 116, 3 credits are consumed. If the player does not have the amount of credit required to install the attack item 116, the attack item 116 will not be installed even if the buttons 10 and 11 are operated.

On the other hand, when a predetermined game result is obtained for the game operation associated with the consumption of credit, such as the enemy character 112 being defeated by the effect of the attack item 116, the player is rewarded. There are a plurality of types of enemy characters 112 having different reward amounts to be given to the player. In the example of FIG. 2, four types of enemy characters 112 are shown separately from each other by hatching. However, the type of the enemy character 112 may be appropriate. By differentiating the shape, color, pattern and other visual elements of the enemy character 112, the enemy character 112 may be displayed in a manner corresponding to the type. FIG. 3C shows an example in which an amount of reward is given according to the type of the enemy character 112. In FIG. 3B, there are two enemy characters 112 in the range of influence 116a, one medal when one enemy character 112 is defeated, and three medals when the other enemy character 112 is defeated. It is assumed that the correspondence between the enemy character 112 and the reward amount is set so that is given as an example of the reward. In that case, as shown in FIG. 3C, the enemy character 112 existing in the influence range 116a disappears, and in exchange for that, one and three medals are generated as rewards, and a total of four medals are given to the player. An effect of presenting to the player that the reward is given is added to the game screen 100.

Although not shown in FIG. 2, the enemy character 112 includes a special character that appears when a special condition is satisfied in the game. The special character is set as an enemy character 112 that consumes more credits to defeat than a normal enemy character and can obtain more rewards, and is called, for example, a boss character or the like. It is a character. For example, a special character cannot be defeated without using the attack item 116 multiple times, and if it is defeated, it is a lot more than the enemy character 112 that can be defeated by using the attack item 116 once. It is set so that you can win medals. The conditions for the appearance of the special character (an example of the switching condition) may be appropriately set according to the convenience of the game. For example, if a predetermined game result is obtained in the game, a predetermined amount of game value is consumed, or the like, conditions may be appropriately set in association with the game.

As described above, in the game illustrated in FIG. 2, the reward amount acquired by the player changes depending on where and at what timing the player installs the attack item 116. If you move the player character 111 and install the attack item 116 aiming at the place where a large number of enemy characters 112 are gathered or the place where the enemy character 112 with a large amount of reward exists, you can defeat more enemy characters 112. Alternatively, the player can obtain many medals by defeating the more valuable enemy character 112. Therefore, the game of FIG. 2 includes a so-called skill game element in which the game result changes according to the skill of the player and the reward amount also changes accordingly.

In the game screen 100 shown in FIG. 2, the information presentation area 102 is provided with four sections 102a to 102d which are distinguished so as to correspond one-to-one with each of the four stations 6 sharing the game screen 100. ing. A credit display unit 103 is provided in each of the sections 102a to 102d. The credit display unit 103 displays the remaining number of credits that the player of the corresponding station 6 can consume in the game.

In the above game, the reward amount given to the player changes depending on the type and number of defeated enemy characters 112, but the game machine 2 is equipped with a function of adjusting the reward amount from the viewpoint of controlling the payout rate. Has been done. An example of the reward amount adjustment is shown in FIG. In the example of FIG. 4, first, the number of medals M as the reward amount originally to be given to the player is determined according to the game result (F1). For example, if the enemy character 112 whose reward medals are set to 1 and 3 is defeated as shown in FIG. 3C, the reward medals are set to 4 respectively. On the other hand, when a predetermined lottery condition is satisfied in the game, a lottery using the computer of the game machine 2 is performed (F2). This lottery is not performed by the center lottery mechanism 7 provided as a physical lottery mechanism in the game machine 2, but is carried out as an internal lottery process in which one of the options is selected according to the lottery probability set for each lottery option. ..

The internal lottery process is executed before or after the reward amount corresponding to the game result is determined. When the game result is determined, the reward amount is adjusted based on the number of medals M as the reward amount corresponding to the game result and the internal lottery result (F3). For example, the number of medals M is adjusted to N. This adjustment is made so that the correspondence between the game result and the reward amount given to the player changes according to the result of the lottery. Then, the adjusted number of medals N is given to the player as a reward (F4). The adjustment of the reward amount based on the lottery result may be executed in an appropriate manner. For example, the upper limit value N of the number of medals that the player can acquire is determined based on the lottery result, then the number of medals M corresponding to the game result is determined, and if the number of medals M is within the upper limit value N, the determination is made. When the number of medals M is given to the player and the upper limit value N is exceeded, the reward amount can be reduced to N or less and given to the player. In this case, the upper limit value has significance as a value that defines the amount of reward that the player can obtain in the future. In addition to the above, instead of the upper limit value, the reward grant rate is determined based on the lottery result, and the reward amount is adjusted by multiplying the original reward amount (the reward amount determined by F1) by the reward grant rate. It is also possible. Alternatively, the adjustment amount to be added or subtracted from the original reward amount is determined based on the lottery result, and the final reward amount is determined by adding or subtracting the determined adjustment amount and the original reward amount. Adjustment is also possible.

When adjusting the number of medals as a reward using the lottery process in this way, the game result changes under the influence of the skill of the player, and the number of medals as a reward also changes accordingly. , The lottery probability can be determined according to the convenience of payout control, and the result can be reflected in the adjustment of the number of medals. Thereby, it is possible to appropriately incorporate the adjustment of the payout rate for the game including the element that gives the reward according to the game operation of the player. The magnitude relationship between the number of medals M and N as the reward amount may be appropriately determined according to the convenience of payout rate control. For example, the adjusted medal number N may be limited to be smaller than the adjusted medal number M, or the adjusted medal number N may be allowed to be larger than the adjusted medal number M. good. The adjustment of the number of medals does not necessarily have to be applied, and a medal of the number M to be given according to the game result is given to the player, and a medal of the adjusted number N is given to the player. The case may be appropriately selected.

FIG. 5 shows an example of adjusting the number of medals to be determined according to the game result of FIG. 3B and giving a reward to the player. In the example of FIG. 3B, four medals are originally given to the player as shown in FIG. 3C for the game result of defeating two enemy characters 112. However, in the example of FIG. 5, the number of medals as a reward is reduced to three. In this case, the effect on the game screen is changed in response to the decrease in the number of medals. For example, for the enemy character 112 for which one medal is set as the reward amount, it is displayed that the enemy character 112 is defeated and disappears as in FIG. 3C, and one medal is obtained in exchange for it. On the other hand, for the enemy character 112 for which three medals are set as the reward amount, the player originally has three medals in response to adjusting the reward so that the total reward amount is reduced by one. Only two medals are given, and the effect is changed so that the enemy character 112 does not disappear and survives. In that case, the effect that the surviving enemy character 112 may be weakened may be performed.

By making the above production changes, it is possible to make the player recognize that the effect of the attack item 116 is insufficient, some enemy characters 112 survive, and the number of reward medals is reduced accordingly. It is possible. In other words, it is possible to suppress the occurrence of a sense of discomfort such as an unnatural reduction in reward. In the example of FIG. 5, the enemy character 112 with three medals is generated as a reward, and the enemy character 112 with one medal is not generated as a reward. As a result, a total of three medals are given as rewards, and the enemy character 112 with three medals set as the reward amount disappears correspondingly, and the enemy character 112 with one medal set survives. , The production may be changed so that a total of 3 medals are given as a reward. Alternatively, the reward is not generated for the enemy character 112 with three medals set, but the reward is generated only for the enemy character 112 with one medal set, so that one medal in total is used as a reward. The effect may be changed so that the enemy character 112 to which three medals are set disappears, while the enemy character 112 to which one medal is set survives. When a plurality of enemy characters 112 are located in the influence range 116a and the reward amount is adjusted within the range of the upper limit value, it is possible to appropriately set which enemy character 112 is selected as the target of the reward amount adjustment. It is possible. For example, the enemy character 112 near the position where the attack item 116 is placed is preferentially selected as the target for generating the reward amount, and the enemy character 112 far from the attack item 116 even if it is located in the influence range 116a is adjusted for the reward amount. The enemy character 112 to be the target of the reward amount adjustment may be selected in consideration of the position in the influence range 116a of the enemy character 112, such as being selected as the target. Alternatively, the enemy character 112 having a large number of medals as a reward amount is preferentially selected as the target for generating the reward amount, and the enemy character 112 having a small number of medals as the reward amount is set as the target for adjusting the reward amount. , The enemy character 112 to be the target of the reward amount adjustment may be selected in consideration of the amount of the reward amount set for the enemy character 112. If the upper limit is an intermediate value for the reward amount set for each of the plurality of enemy characters 112, no reward is generated for the enemy character 112 for which the reward amount exceeding the upper limit is set. , The reward may be generated only for the enemy character 112 for which the reward amount equal to or less than the upper limit is set. For example, when the upper limit is set to 2 medals, the enemy character 112 whose reward amount is set to 3 medals and the enemy character 112 whose reward amount is set to 1 are located in the influence range 116a. In this case, no reward is generated for the enemy character 112 for which three medals are set, and only the enemy character 112 for which one medal is set is rewarded. However, even in such a case, if there are a plurality of enemy characters 112 selected as targets for generating rewards and the total value of those rewards exceeds the upper limit, the reward amount will be equal to or less than the upper limit. , It is necessary to adjust the reward amount corresponding to at least some enemy characters 112.

Next, a specific example of the control system of the game machine 2 having the above-mentioned adjustment function will be described with reference to FIGS. 6 to 14. In the following, as an example of adjusting the reward amount described with reference to FIG. 4, the reward amount is adjusted using the above-mentioned upper limit value. FIG. 6 shows an example of a specific configuration of the control system of the game machine 2. The game machine 2 is provided with a control device 20 and a storage device 21. The control device 20 is a computer that combines a microprocessing unit (MPU) as an example of a processor that executes various arithmetic processes and operation controls according to a predetermined computer program, and an internal memory and other peripheral devices necessary for the operation. It is configured. The storage device 21 is an external storage device for the control device 20, and is a storage device including a magnetic disk storage device, a flash memory, and other non-volatile storage media capable of holding storage.

The storage device 21 records a game program PG and a game data DG as an example of a computer program that causes the control device 20 to execute various processes necessary for providing the above-mentioned game to the player. The game data DG includes various data such as data defining the game field 110, image data representing the player character 111 and the enemy character 112, and image and sound data to be used for the production of the game. The game data DG includes a normal odds table ODn and a special odds table ODs as data related to the setting of the upper limit value of the reward amount. These odds tables ODn and ODs are data tables referred to in a lottery performed to adjust the reward amount.

An example of the normal odds table ODn is shown in FIG. 7, and an example of the special odds table ODs is shown in FIG. As is clear from these figures, the odds tables ODn and ODs are data recorded in association with the addition amount N of the upper limit of the number of medals that can be given to the player and the lottery probability. The addition amount N corresponds to an example of lottery options. By adjusting the lottery probabilities of the odds tables ODn and ODs, the payout rate in the game can be set appropriately. The total amount of game value (number of credits) consumed by the player in the game during the predetermined aggregation period is defined as A, and the reward amount given to the player within the same aggregation period (number of medals granted as reward) is defined as B. When controlling the payout rate B / A to be less than 1, as an example, the lottery probability P1 can be set to 0.29, P2 can be set to 0.68, P3 can be set to 0.02, and P4 can be set to 0.01, respectively. ..

The addition amount N of the odds tables ODn and ODs and the lottery probability determine the expected value of the upper limit value determined based on the lottery result. That is, the sum of the products of each addition amount N and the lottery probability is the expected value of the addition amount, and the sum of the expected value and the upper limit value before adding the addition amount N indicates the expected value of the upper limit value after the lottery. .. The special odds table ODs are used in a special state in which the above-mentioned special character appears and a state is generated in which the player can obtain more rewards. Corresponding to the possibility of obtaining a large amount of reward, the upper limit addition amount of the special odds table ODs is set larger than that of the normal odds table ODn, and the expected value of the upper limit is also set larger accordingly. ing. The addition amount described in the odds tables ODn and ODs does not necessarily have to be a positive integer. The addition amount with a decimal point may be included in the odds tables ODn and ODs. Further, as a kind of loss of the lottery, a part of the addition amount may be set to a negative value.

The play data DP is also recorded in the storage device 21. The play data DP is stored in the game server 4 in association with the player ID, which is the identification information of the player, and is provided to the game machine 2 and stored in the game machine 2 on condition that the player authenticates when the player plays the game on the game machine 2. Recorded on device 21. The play data DP recorded in the storage device 21 is updated at an appropriate timing according to the progress of the game in the game machine 2, and is provided to the game server 4 from the game machine 2 and stored when the game ends. ..

The play content of the player in the game machine 2 may be appropriately recorded in the play data DP, but in the illustrated example, the upper limit data DU is included in the play data DP. The upper limit value data DU is information for designating the upper limit value of the reward amount set for the player. By including the upper limit value data DU in the play data DP, the upper limit value set for the player in the past game is held in association with the player ID, and the same player plays the game according to the upper limit value in the next and subsequent games. Can be played from the continuation. However, the upper limit value is not limited to the mode of holding it in association with the player ID. This point will be described later.

The control device 20 is provided with a game processing unit 22 as a logical device realized by combining the hardware resources of the control device 20 and the game program PG as software resources. The game processing unit 22 executes various processes necessary for playing a game on the game machine 2 according to the game program PG. The details of the game processing unit 22 will be described later.

The display device 5, the center lottery mechanism 7, the input device 8, the reader 12, the medal receiving device 15, and the speaker device 17 shown in FIG. 1 are connected to the control device 20, and the medal payout device 26 and the communication control device 27 are connected. Is connected. The medal payout device 26 is a device for paying out medals to the payout outlet 16 (see FIG. 1). The communication control device 27 is a device for controlling communication between the control device 20 and the game server 4. In addition to the above, an appropriate input / output device may be connected to the control device 20, but the description thereof will be omitted here.

FIG. 9 shows an example of a specific configuration of the game processing unit 22. In the game processing unit 22, as further logical devices, a game operation reception unit 30, a credit management unit 31, a game control unit 32, a reward amount determination unit 33, a reward giving unit 34, a game screen generation unit 35, and a reward production instruction unit 36 is provided. The game operation reception unit 30 receives the player's game operation on the input device 8. The credit management unit 31 manages the number of credits by adding or subtracting from the credit data DC that describes the quantity of credits owned by the player. When the game operation reception unit 30 detects a game operation subject to the consumption of credits, such as the operation of the buttons 10 and 11 of the input device 8, the game operation reception unit 30 should be consumed in exchange for the game operation. The credit management unit 31 is instructed to subtract the number of credits, and the game operation is accepted on condition that the credit management unit 31 subtracts the instructed number of credits. The credit data DC is data temporarily generated in the internal memory of the control device 20. When the player ends the game, the number of medals corresponding to the number of credits held in the credit data DC is paid out to the player from the medal payout device 26, so that the unused credits are returned to the player as medals. good. At the end of the game, the credit data DC is recorded in the storage device 21 as a part of the play data DP, and this is stored in the game server 4 in association with the player ID, so that unused credits can be taken over in the next game. May be available at.

The game control unit 32 executes various operations necessary for the progress of the game based on the game operation received by the game operation reception unit 30. For example, in the game shown in FIG. 2, the game control unit 32 repeatedly calculates the position of the enemy character 112 and calculates the position of the player character 111 according to the player's game operation with respect to the input device 8. Further, the game control unit 32 calculates the position of the attack item 116 when the game operation for arranging the attack item 116 is performed, and calculates the effect according to the position and type of the attack item 116 as the game result. ..

The reward amount determination unit 33 determines the number of medals as a reward to be given to the player based on the game result calculated by the game control unit 32. The reward giving unit 34 gives a reward to the player by instructing the credit management unit 31 to add an amount of credit corresponding to the number of medals determined by the reward amount determining unit 33 to the credit data DC. The game screen generation unit 35 repeatedly generates the game screen 100 so that the game progresses according to the game result calculated by the game control unit 32. The reward effect instruction unit 36 draws an effect image (as an example, an image shown in FIG. 3C or FIG. 5) representing a state in which the player has acquired the reward determined by the reward amount determination unit 33 on the game screen 100. Instruct the game screen generation unit 35 to add an effect related to reward granting, and provide the game screen generation unit 35 with information necessary for adding the effect.

In order to realize the above-mentioned adjustment of the reward amount, the reward amount determination unit 33 is provided with a standard reward amount determination unit 40, a lottery unit 41, and a reward amount adjustment unit 42. When the standard reward amount determination unit 40 includes a result for which a reward should be given to the game result calculated by the game control unit 32, for example, in the game of FIG. 2, the enemy character is in the influence range 116a of the attack item 116. When the result that 112 is present is included, the number of medals as the reward amount set according to the type of the enemy character 112 is determined as the standard reward amount. For example, in the case of FIG. 3C, the number of medals is determined to be one and three for each of the two enemy characters 112 included in the influence range 116a.

When a predetermined lottery condition is satisfied in the game, the lottery unit 41 executes a lottery process for determining the addition amount of the upper limit value related to the adjustment of the reward amount. The lottery of the lottery unit 41 is performed based on the odds table ODn or ODs (hereinafter, may be represented by the reference numeral OD) shown in FIG. 7 or FIG. The reward amount adjusting unit 42 is the number of medals determined by the standard reward amount determination unit 40 based on the lottery result of the lottery unit 41 (the reward amount to be determined according to the game result, hereinafter referred to as the standard reward amount). May be adjusted.) The adjustment is performed so that the correspondence relationship between the game result and the reward amount given to the player changes from the correspondence relationship between the reward amount determined by the standard reward amount determination unit 40 and the game result. Then, the adjustment is realized by limiting the upper limit of the reward amount according to the lottery result of the lottery unit 41. In order to realize the adjustment, the reward amount adjustment unit 42 is provided with an upper limit value management unit 43 and a reward regulation unit 44. The upper limit value management unit 43 adds the upper limit value of the reward amount held in the upper limit value data DU according to the lottery result of the lottery unit 41, or subtracts it according to the reward amount given by the reward regulation unit 44. The remuneration control unit 44 compares the size of the standard remuneration amount determined by the standard remuneration amount determination unit 40 with the upper limit value recorded in the upper limit value data DU, and if the standard remuneration amount exceeds the upper limit value, , The reward amount is subtracted so that the reward amount given to the player is equal to or less than the upper limit value. When the standard reward amount is within the upper limit value, the reward regulation unit 44 determines the standard reward amount as the reward amount to be given to the player.

FIG. 10 shows an example of a game processing procedure that the game processing unit 22 repeatedly executes at a predetermined cycle (as an example, the frame rate of the display device 5). The process of FIG. 10 is a process performed independently for each station 6. Hereinafter, the procedure of FIG. 10 will be described as a process for any one of the stations 6. In the process of FIG. 10, it is assumed that the player ID related to the player of the target station 6 has already been determined. When the time to execute the process of FIG. 10 arrives, the game operation reception unit 30 first determines whether or not the game operation for which the credit is to be consumed has been performed (step S10). As an example, if the button 10 or 11 is operated, it is determined that the game operation of the consumption target has been performed, and if the input device 8 is not operated or only the operation lever 9 is operated, the operation of the consumption target is performed. It is determined that it has not been done. When it is determined that the operation of the consumption target has not been performed, the processing of steps S11 to S14 is skipped, and the game control unit 32 calculates the game result to be reflected on the game screen 100 of the next frame (step). S15). In this case, for example, the position of the enemy character 112 in the next frame is calculated, and if the operation lever 9 is operated, the position of the player character 111 is calculated according to the operation.

On the other hand, when it is determined in step S10 that the game operation for which the credit is to be consumed has been performed, the game operation reception unit 30 records in the credit data DC more credits than should be consumed in response to the game operation. Whether or not, that is, whether or not the amount of game value owned by the player is equal to or greater than the consumption amount corresponding to the game operation is determined via the credit management unit 31 (step S11). When the credit is sufficient, the game operation reception unit 30 accepts the player's game operation as valid, notifies the game operation to the game control unit 32, and informs the credit management unit 31 of the number of credits in the credit data DC. Is instructed to be subtracted by the amount corresponding to the consumption amount corresponding to the game operation (step S12). As a result, the number of credits owned by the player is consumed by the amount corresponding to the operation of the button 10 or 11. When it is determined in step S11 that the credit is insufficient, that is, when the amount of the game value owned by the player is less than the consumption amount corresponding to the game operation, the game operation reception unit 30 invalidates the game operation of the player. In that case, the processing of steps S12 to S14 is skipped, and the game processing proceeds to step S15.

When the game operation is accepted in step S12, the game operation reception unit 30 also notifies the lottery unit 41 to that effect. The lottery unit 41 considers that the lottery conditions have been satisfied because the game operation is accepted in exchange for the consumption of credits, and executes the internal lottery process (step S13). The internal lottery is usually a process of determining the amount to be added to the upper limit of the reward amount by using the odds table ODn or the special odds table ODs, but the details will be described later. When the lottery unit 41 determines the addition amount of the upper limit value, the addition amount is notified to the upper limit value management unit 43. The upper limit value management unit 43 updates the upper limit value data DU so that the addition amount notified from the lottery unit 41 is added to the upper limit value held in the player's play data (step S14). However, when the addition amount is determined to be 0 in the lottery in step S13, the upper limit data DU is not substantially updated. In that case, the upper limit does not increase until the additional amount larger than 0 is drawn at the next or subsequent lottery opportunity.

After the processes of steps S12 to S14 are sequentially executed, the game process proceeds to step S15. In that case, the game control unit 32 calculates the game result corresponding to the game operation notified from the game operation reception unit 30 by the process of step S12 (step S15). In this case, the position of the enemy character 112 in the next frame is calculated and the like in the same manner as when the process proceeds from step S10 or step S11 to step S15, but in addition to this, the operation of the buttons 10 and 11 is performed. The position where the corresponding type of attack item 116 should be placed is calculated. If the operation lever 9 is operated in parallel with the operation of the buttons 10 and 11, the position of the player character 111 is also calculated.

When the game result is calculated in step S15, the game control unit 32 subsequently determines whether or not the condition for generating the reward is satisfied based on the calculated game result (step S16). When it is determined that the condition is satisfied, the reward amount determination unit 33 tells the player based on the game result calculated by the game control unit 32 and the upper limit value held in the upper limit value data DU. The amount of reward to be given is determined (step S17). The details of the procedure for determining the amount of reward will be described later. When the reward amount is determined, the reward amount determination unit 33 notifies the reward granting unit 34 of the reward amount, and the reward granting unit 34 receiving the reward corresponds to the number of medals as the reward amount to the credit management unit 31. Notify the credit management unit 31 to add the amount of credit (step S18). As a result, an amount of credit corresponding to the reward amount is added to the credit data DC of the player. Further, after the reward amount is determined, the reward production instruction unit 36 is notified of the content of the reward determination. In response to this, the reward effect instruction unit 36 instructs the game screen generation unit 35 to add an effect indicating how the player obtains the reward to the game screen 100, and generates information necessary for the effect on the game screen. It is provided to the unit 35 (step S19). After that, the process proceeds to step S20, and the game screen generation unit 35 generates the game screen 100. In this case, if the reward is given to the player without reducing the reward amount to the upper limit or less, the enemy character 112 is defeated and the number of medals set corresponding to the enemy character 112 is given. (FIG. 3C), when the reward amount is reduced to the upper limit or less and given to the player, the effect changes according to the adjustment (FIG. 5).

FIG. 11 shows an example of a specific procedure of the internal lottery executed in step S13 of FIG. In the example of FIG. 11, the lottery unit 41 first acquires information for determining the state of the game from the game control unit 32, and determines whether or not the game is in a special state (step S30). As described above, the special state is a state in which the player can expect to acquire more rewards, such as the appearance of a special character as the enemy character 112. If it is determined that the game is not in a special state, the lottery unit 41 considers the game to be in a normal state and selects the normal odds table ODn (step S31), and if it is determined to be in a special state, selects the special odds table ODs. (Step S32). After selecting the odds table OD, the lottery unit 41 draws the addition amount of the upper limit value according to the lottery probability of the selected odds table OD (step S33). Subsequently, the lottery unit 41 notifies the reward amount adjustment unit 42 of the addition amount of the lottered upper limit value as the lottery result (step S34), and then ends the process of FIG. 11. When the addition amount is notified in step S34, the upper limit value management unit 43 updates the upper limit value data DU so that the addition amount is added to the upper limit value of the upper limit value data DU (step S14 in FIG. 10). In FIG. 11, the odds table OD is switched depending on whether it is a normal state or a special state, but three or more types of odds tables may be switched and used depending on the state of the game.

FIG. 12 shows an example of a specific procedure for determining the amount of reward executed in step S17 of FIG. In the example of FIG. 12, the standard reward amount determination unit 40 acquires the game result from the game control unit 32 and determines the standard reward amount corresponding to the game result (step S40). As described above, the standard reward amount is the number of medals determined according to the correspondence between the preset enemy character 112 and the reward amount. For example, when the enemy character 112 for which three medals are set as the reward amount is defeated, the standard reward amount is three medals. The standard remuneration amount determination unit 40 notifies the remuneration regulation unit 44 of the determined standard remuneration amount, and the remuneration regulation unit 44 indicates whether the notified standard remuneration amount exceeds the upper limit value recorded in the upper limit data DU. Whether or not it is determined (step S41). If not exceeded, the reward control unit 44 determines the standard reward amount as the reward amount to be given to the player (step S42). On the other hand, if it is determined in step S41 that the standard reward amount exceeds the upper limit value, the reward control unit 44 determines an integer value in the range not exceeding the upper limit value as the reward amount to be given to the player (step S43). ). For example, when the standard reward amount is 4 medals and the upper limit is 3, 0 to 3 medals are determined as the reward amount. The standard reward amount is determined as a positive integer, while the upper limit is allowed to have a decimal point. Therefore, if the upper limit is less than 1, the reward amount is determined to be 0 regardless of the standard reward amount.

After determining the reward amount, the reward control unit 44 notifies the reward granting unit 34 of the reward amount (step S44). After that, the reward control unit 44 instructs the upper limit value management unit 43 to subtract the reward amount determined in step S42 or S43 from the upper limit value recorded in the upper limit value data DU, and receives the upper limit. The value management unit 43 subtracts the reward amount from the upper limit value of the upper limit value data DU (step S45). As a result, unless the upper limit value is added in step S14 of FIG. 10, the upper limit value is gradually subtracted each time the reward is given.

FIG. 13 shows an example of a specific procedure of the reward-related effect instruction executed in step S19 of FIG. In the example of FIG. 13, the reward production instruction unit 36 acquires information for specifying the content of the reward amount determination process of FIG. 12 from the reward regulation unit 44 (step S50). Next, the reward production instruction unit 36 determines whether or not the reward amount has been adjusted to the upper limit value or less by the reward regulation unit 44 based on the obtained information (step S51). When the reward amount is not adjusted and the standard reward amount is determined as the reward amount given to the player, the reward production instruction unit 36 has a correspondence relationship between the enemy character 112 defeated in this game result and the reward amount. According to this, the game screen generation unit 35 is instructed to add a standard effect (as an example, the effect shown in FIG. 3C) indicating to the player that the reward is given to the player and the enemy character 112 disappears, and the information necessary for the effect is given to the game. It is provided to the screen generation unit 35 (step S52). For example, information for designating the defeated enemy character 112 and information for specifying the number of medals acquired by the player as a reward are provided.

On the other hand, when it is determined in step S51 that the reward amount has been adjusted, the reward effect instruction unit 36 adds an effect (as an example, the effect of FIG. 5) in which the standard effect is changed according to the adjustment result of the reward amount. Is instructed to the game screen generation unit 35, and information necessary for the production is provided to the game screen generation unit 35 (step S52). For example, as a result of adjusting the reward amount, information is provided that specifies the enemy character 112 that should be displayed so as to survive without being defeated, and information that specifies the number of medals that the player has acquired as a reward. In this case, if there is an enemy character 112 defeated in the result of this game, information for designating the enemy character 112 and information for designating the reward amount corresponding to the result are also provided. After the instruction in step S52 or S53, the reward production instruction unit 36 finishes the process of FIG. If the reward amount is determined to be 0 due to the limitation of the upper limit value, the reward generation effect is not performed. In this case, the enemy character 112 may be extinguished, and the effect may be performed so that the enemy character 112 has no reward set, or the enemy character 112 survives without being affected by the attack item 116. The production may be performed.

According to the above processing, the player is given an opportunity to obtain a reward on condition that the credit as the game value is consumed, and the game result corresponding to the reward giving such that the player defeats the enemy character 112 by using the attack item 116 is obtained. Once obtained, the player is rewarded. As a result, for example, the more the player effectively arranges the attack item 116 and defeats more enemy characters 112, or the more valuable enemy character 112 is defeated, the more reward the player is given. The skill of the player can be reflected in the reward grant. On the other hand, the amount of reward that the player obtains is limited by the upper limit, and rewards exceeding a certain limit cannot be obtained. The upper limit of the reward amount is determined by a lottery executed in association with the consumption of credits by the player. Therefore, by appropriately adjusting the probability of the lottery, the reward is controlled so that the payout rate is maintained within a predetermined range in which the operating entity of the game system 1 or the game machine 2 can secure an appropriate profit. be able to. As a result, it is possible to incorporate the control of the payout rate into the game including the element that the reward increases or decreases according to the skill of the player, and to achieve both the satisfaction of the player and the securing of an appropriate profit by controlling the payout rate. .. Furthermore, if the reward is adjusted due to the limitation of the upper limit, the effect is changed accordingly. Therefore, it is possible to enhance the convincing feeling of the player and reduce the possibility that the player recognizes the intervention of the control of the payout rate and loses the interest of the game.

In the game system 1 described above, the upper limit of the reward amount is stored in association with the player ID, so that the same player can take over the previous upper limit and play the next game. FIG. 14 shows an example of the procedure of the upper limit value saving process executed by the control device 20 of the game machine 2 in order to save the upper limit value in association with the player ID. As an example, this process may be executed by the upper limit value management unit 43. For example, the upper limit value management unit 43 starts the process of FIG. 14 when the player ends the game, first determines the player ID of the player, and determines the play data DP based on the determined player ID. (Step S60), and then, the upper limit data DU is stored in the determined play data DP (step S61). When the game server 4 is available, the play data DP in which the upper limit data DU is stored may be stored in the game server 4 in association with the player ID. When the upper limit data DU is stored in the storage device 21 of the game machine 2 in association with the player ID, when the player restarts the game on the same game machine 2, the player ID is identified and the corresponding play data DP is stored. It is possible to reuse the previous upper limit value by reading. If the play data DP is stored on the game server 4, the previous upper limit value can be reused even when the player restarts the game on a different game machine 2.

Instead of the player ID, at least one input device 8 of the game machine 2 may be used as a unit, and the upper limit value may be managed for each unit. For example, as an example of input device identification information for identifying the input device 8, a unique station ID is set for each station 6, the upper limit value is increased or decreased for each station ID, and the upper limit value at that time is reached at the end of the game. The data DU may be saved in association with the station ID, and then the player playing at the same station 6 may take over the upper limit data DU. In that case, the upper limit value management unit 43 may execute the process of FIG. 15 instead of the process of FIG. That is, in the process of FIG. 15, the upper limit value management unit 43 starts the process of FIG. 15 when the player ends the game, first determines the station ID of the player's station 6 (step S60A), and then determines. The upper limit value data DU is stored in the storage device 21 in association with the station ID (step S61A). In this case, the next time play is started at the same station 6, the upper limit data DU corresponding to the station ID is read from the storage device 21, and the upper limit data DU is used for playing the game at that station 6. If so, the upper limit can be taken over.

In either case where the upper limit value is managed in association with the player ID or in the case where the upper limit value is managed in association with the station ID, the upper limit value is set in association with one player. However, the upper limit may be set in common for two or more players. For example, a group including a plurality of players may be set, and a common upper limit value may be set for each group. Alternatively, a common upper limit value may be set in units of a plurality of stations 6 of one game machine 2. Further, a common upper limit value may be set for each of a plurality of game machines 2.

In the above embodiment, the game operation reception unit 30 functions as an example of the game operation reception means by executing the processes of steps S11 and S12 of FIG. 10, and the game control unit 32 executes the process of step S15 of FIG. By doing so, it functions as an example of the game control means, the reward amount determination unit 33 functions as an example of the reward amount determination means by executing the processes of steps S13, S14, and S17 in FIG. By executing the process of step S18 of 10, it functions as an example of the reward giving means. Further, the lottery unit 41 functions as an example of the lottery means by executing the process of FIG. 11, and the reward amount adjusting unit 42 executes the processes of steps S41 to S45 of FIG. 12 and the processes of FIGS. 14 or 15. This functions as an example of the reward amount adjusting means. Further, the reward effect instruction unit 36 functions as an example of the reward effect control means by executing the process of FIG. 13.

The present invention is not limited to the above-mentioned form, and may be carried out in a form in which appropriate modifications or changes are made. For example, in the above embodiment, the addition amount of the upper limit value is drawn assuming that the lottery condition is satisfied every time the player consumes the game value, but the lottery condition may be changed as appropriate. For example, it is established when the consumption amount of the game value of the player reaches a predetermined amount, or is established when the consumption number of the game value reaches a predetermined number, and is associated with the consumption amount or the number of times of consumption of the game value. The lottery conditions may be set. In this case, the predetermined amount may be set larger than the consumption amount for one game operation. A lottery condition may be set in association with the reward amount so that it is established when the reward payout amount reaches a certain value. Alternatively, even if the lottery condition is set in association with the game result, for example, the lottery condition is satisfied when a predetermined game result is obtained, for example, when at least one enemy character 112 is defeated in the game of FIG. good. Alternatively, the lottery conditions may be set so that the lottery conditions are satisfied when the number of times the player plays the game, the play time, and the like reach a predetermined reference value. Furthermore, the lottery conditions are not limited to the examples set in direct association with the game. For example, the lottery conditions may be set in association with the time and date, such that the lottery conditions are satisfied at a predetermined time, a predetermined day of the week, and a predetermined day of each month.

In the above mode, each time the player performs a game operation, the amount of game value corresponding to the operation is consumed, but the correspondence relationship between the game operation and the consumption of the game value is appropriately set. It's okay. For example, a plurality of game operations may be accepted by consuming one game value. By consuming the game value once, the game operation may be accepted without limiting the number of times within a predetermined time. In the above mode, as an example of the game operation, an operation of operating the button 10 or 11 to place the attack item 116 is given as an example, but a plurality of types of game operations accepted in exchange for the consumption of the game value may be set. ..

In the above embodiment, the lottery probability and the addition amount of the odds tables ODn and ODs are set in advance, and the review may be appropriately performed by, for example, the operating entity of the game machine 2. However, the payout rate is monitored during the operation of the game machine 2, and when the payout rate approaches or exceeds the upper limit or the lower limit of the predetermined range, the payout rate determines the lottery probability and the addition amount of the odds tables ODn and Ods. A control may be added to dynamically change the odds tables ODn and ODs according to the fluctuation of the payout rate, such as changing the odds tables so as to converge to the range.

In the above embodiment, the game system 1 is configured so that a plurality of players can play the same game in parallel on one game machine 2, but the present invention is not limited to such an embodiment. For example, one game machine 2 suffices to be provided with at least one input device 8. Even in that case, it is possible for a plurality of players to play the game at different times from each other, and the payout rate as the ratio of the total value of the reward amount to the total value of the player's consumption amount within a predetermined period is within a predetermined range. The present invention may be applied so as to be maintained in. Further, the game system is not limited to the form of using a game machine that can obtain a payout rate by itself, such as an arcade game machine. For example, as shown in FIG. 16, a user terminal device 2A such as a smartphone used by a user personally and a game server 4 are connected via a network 3, and under the control of the game server 4, on the user terminal device 2A. The present invention can also be applied to a game system of a type in which each user is allowed to play a game. For example, even in the form of an online casino game, by applying the present invention, it is possible to control the payout rate within an appropriate range while reflecting the skill of the player in the reward amount.
