Description

  The present invention relates to a game system, a game device, a central device, and a program.

  Conventionally, a link-type jackpot game system has been provided. This generally comprises the following configuration. That is, the first is a plurality of game devices, and the second is a central device that is communicably connected to the plurality of game devices. Among these, the game device includes a game terminal that provides various games such as a pusher game, a slot game, and a horse racing game. A plurality of game terminals can be included in one game device. Each game terminal typically provides various games by inserting medals by players. Depending on the result of the game, the player is given a medal according to the number of inserted medals, or given a sanctions for confiscation of the inserted medals.

On the other hand, the central device has a function of giving a medal as a privilege unexpectedly to the player regardless of the result of the game at each game terminal. The execution of the medal payment as the privilege is performed after a specific game terminal is drawn and determined as a terminal that benefits from the privilege according to a predetermined lottery probability. Further, the number of medals as the privilege depends on the number of medals that each player has spent at each game terminal so far. This is also a return service including lottery elements for users of the game system.
As such a game system, for example, a game system disclosed in Patent Document 1 is known.

JP 2009-112733 A

By the way, the game system as described above has the following problems.
First, the medal payment as a privilege as described above is preferably performed uniformly for a plurality of game devices or a plurality of game terminals constituting them, but such a guarantee is not necessarily provided on the system. It is not secured. Therefore, in some cases, it may not happen that a jackpot win is biased with respect to a specific game terminal.

  In addition, as described above, such a game system includes a plurality of types of game devices or game terminals. Among them, there is a possibility that a distinction between a popular model and an unpopular model occurs. This distinction is due to the difference in appeal of the game itself provided by the game terminal or appeal to the customer, or due to a difference in the layout of each game terminal in the store (for example, when the store has two stories) In addition, a game terminal installed on the first floor often comes with a player, but a game terminal installed on the second floor does not. However, the game system administrator usually does not like such a bias. This is because, as a whole, it is preferable in terms of operation that medals are consumed uniformly as a whole game system.

  The present invention has been made in view of the above-described circumstances, and the appearance of jackpot winning can be suitably adjusted, or if a distinction between popular and unpopular models occurs, jackpot winning It is an object of the present invention to provide a game system, a game device, a central device, and a program that can be appropriately operated as a whole, such as being able to eliminate it by changing the appearance mode of .

In order to solve the above-described problem, the game system according to the present invention is a game that participates by consumption of an intangible game medium that is recorded tangibly or electrically or magnetically, and is a number corresponding to the result of the game. A game device having one or two or more game terminals that allow a player to play a game paying the game medium, and a plurality of game devices that are communicably connected, and for any one or more of the game terminals, A central device that commands to pay a predetermined number of game media as a privilege, and a consumed game media that is the number of game media consumed within a predetermined first period retroactive from the present time for each game terminal of each game device A game system including a counting unit that counts a number and a determination unit that determines whether or not each game terminal is played, wherein the central device is triggered by a predetermined opportunity. Based on the constant of the lottery probability, a lottery unit which performs a lottery for determining whether an instruction to pay for game contents as the privilege, the winning rate correction value corresponding to each game device connected to the central unit And a game unit of each game device connected to the central device when it is determined to instruct payment of the game medium as the privilege by lottery by the lottery unit. The winning rate relating to the game terminal being played is determined based on the number of consumed game media for the playing game terminal determined to be played by the determination unit and the winning rate correction value. And a determination unit that determines a game terminal to be instructed to pay the game content as the privilege by a lottery according to the winning rate, and determined by the determination unit Game terminal that pays the game medium as the benefits for the predetermined number.

  According to the present invention, there is provided a so-called link-type jackpot game system in which “game media as a privilege (for example, medal)” is paid by lottery according to a winning rate. In the present invention, in particular, since the winning rate correction value that provides one criterion for determining the winning rate is set to be variable, the winning rate can also be changed accordingly. Therefore, from the viewpoint of the entire system, according to the present invention, in the case where there is a bias such as jackpot winnings concentrated only on game terminals belonging to a specific game device, the winning rate correction value is appropriately set. By setting, it is possible to perform an appropriate operation of the system, such as taking appropriate measures such as leveling the bias.

In the present invention, the “counter” may be installed as if it is an independent element in the game system in terms of physical recognition. ”,“ Game device ”, or“ game terminal ”may be installed as a part. The same applies to the “determination unit”.
In addition, each element and each term defining the present invention will be described in more detail in a later embodiment in accordance with one specific example. In particular, for the meaning of “consumption” in the case of “consumed game media”, refer to the description in the later embodiments.

In the game system according to the present invention, the predetermined number that is the number of game media as the privilege is obtained by cumulatively adding according to the number of game media consumed at each game terminal of each game device. It is a part or all of the number of stored game media, and after the game media as the privilege is paid, the central device subtracts the predetermined number from the number of stored game media, or a predetermined initial number, You may comprise so that the control part which updates the said number of accumulation | storage game media may be further included.
According to this aspect, the number of game media as benefits to be paid is cumulatively added according to the number of game media consumed at each game terminal. Can be increased. This is because the increase in the number of game media as a privilege itself becomes a factor that attracts players to the game terminal.

In the game system according to the present invention, the predetermined opportunity related to the lottery unit includes a time when one or more game media are consumed in each game terminal, and the predetermined lottery probability related to the lottery unit May be configured to correspond to the number of game media consumed when one or more game media are consumed.
According to this aspect, it is possible to suitably set the lottery trigger and probability governing the occurrence of jackpot winning.

Further, in the game system according to the present invention, the predetermined opportunity related to the lottery unit includes a time when a predetermined number of game media are consumed within a predetermined second period at each game terminal, You may comprise so that the said predetermined | prescribed lottery probability which concerns on a lottery part respond | corresponds to the said regulation consumption number.
According to this aspect, if the prescribed consumption number is suitably determined, the chance of confirming whether or not the game medium is consumed is reduced, resulting in a decrease in communication opportunities between the central device and the game device or game terminal. The effect of reducing the communication load of the entire system is obtained.

Moreover, in the game system according to the present invention, the setting unit automatically sets the winning rate correction value for each game device so that the winning rate for each game terminal approaches the same value. You may comprise as follows.
According to this aspect, the distinction between the popular model and the unpopular model described above can be effectively eliminated. This means that if both the winning rate for game terminals that are popular models and the winning rate for game terminals that are unpopular models are nearly the same, jackpot wins for all game terminals are easier to win. This is because customer attraction is the same.

In the game system according to the present invention, the setting unit may include an operation unit for changing the winning rate correction value by an external operation.
According to this aspect, for example, the administrator of the game system manually changes the winning rate correction value in consideration of various circumstances such as the above-described distinction between popular models and unpopular models. Since the winning rate for each game device can be changed, the effect according to the present invention, that is, the effect of appropriate operation of the game system is more effectively achieved.

In the game system according to the present invention, after the winning rate correction value is set by the setting unit, the central device determines the winning rate correction value after the setting and all the game terminals at the time of the setting. You may comprise further including the display part which displays the total prediction winning rate about each said game device defined based on the said number of game medium to be consumed.
According to this aspect, since it is possible to visually recognize and confirm the overall expected winning rate for each game device determined based on the winning rate correction value after setting by the setting unit, for example, appropriate measures ( More specifically, for example, if the value after setting is unsatisfactory, it is possible to obtain an advantage that it is easier to change the setting.
The significance of the “total expected winning rate” in this aspect will be described in a later embodiment.

Further, in the game system according to the present invention, the determination unit determines that the number of game media consumed is a second predetermined number within a third period shorter than the predetermined first period going back from the current time in a certain game terminal. Based on whether it is the above, you may comprise so that the presence or absence of the play about the said game terminal may be determined.
According to this aspect, it is possible to eliminate an inconvenient player who is giving up jackpot winning. The reason and the like will be mentioned in (1) of the description of the modification in the later embodiment.

Further, in the game system according to the present invention, the payment of the game medium as the privilege is a case where a game terminal to which the game medium as the privilege is to be paid is a pusher game machine, and the game medium is a tangible object. In such a case, the game medium as the privilege may be configured to be included in the pusher table of the pusher game machine.
According to this aspect, since the payment mode of the game medium as a privilege is diversified, it is possible to further increase the interest of the player in the game system.

In the game system according to the present invention, the payment of the game medium as the privilege temporarily disables the play on the game terminal that should pay the game medium as the privilege, and directly receives the game medium as the privilege. The game terminal executes at least one of a notification prompting the player and a notification prompting the administrator of the game system to directly hand over the game media as the privilege. It may be configured as follows.
According to this aspect, for example, when the number of game media as a privilege becomes very large, the direct payment from the game terminal to the player of the game medium as the privilege may cause some adverse effects. The occurrence of a serious situation can be avoided in advance.

In order to solve the above-described problem, the game device according to the present invention is a game that participates by consumption of an intangible game medium that is recorded tangibly or electrically or magnetically, and a number corresponding to the result of the game A game device having one or more game terminals that allow the player to play a game paying the game medium, and based on a predetermined lottery probability at a predetermined opportunity, to any one or more of the game terminals On the other hand, a central device including a lottery unit that performs a lottery to determine whether or not to command a predetermined number of payments of game media as a privilege, and consumption within a predetermined first period retroactive from the present time for each game terminal A game system comprising: a counting unit that counts the number of consumed game media that is the number of game media played; and a determination unit that determines whether or not each game terminal is played When the game device includes a game terminal that is instructed to pay the game medium as the privilege, the determination unit determines that the game terminal is being played. The winning rate determined based on the number of game media consumed for the game terminal and the winning rate correction value set variably for the game device by the setting unit included in the central device.

It is a flowchart which shows the flow of a setting process of a winning rate correction value. It is explanatory drawing which shows the specific example of the operation / display part 131 shown in FIG.

Hereinafter, an embodiment according to the present invention will be described with reference to FIGS. 1 and 2.
As shown in FIG. 1, the game system 100 includes a jackpot device 10 and a game device 20. Of these, the game device 20 is composed of a plurality of game devices 20A, 20B, 20C,... C,... May be omitted if it is not necessary to distinguish these game devices. The subscripts such as determination units 22A, 22B, 22C,..., Or terminals 21A1, 21A2,.

The game device 20 includes various elements such as a terminal 21, a determination unit 22, a communication unit 23, and a control unit 24.
Among these, first, the control unit 24 includes a CPU, a RAM, a ROM, and the like (not shown), and directly and indirectly controls other various elements so that the game device 20 as a whole operates in a harmonious manner.

The terminal 21 is a device for causing the player to perform a game while receiving a direct operation by the player. The “game” can be, for example, a slot game, a puzzle game, a pusher game, a horse racing game, a mahjong game, or the like, and the type is not particularly concerned in the present invention. The operation that the player should perform on the terminal 21 depends on the type of game.
One or more such terminals 21 are installed as one game device 20. For example, the game apparatus 20A includes four terminals 21A1 to 21A4 as shown in FIG. As described immediately above, since the present invention is not related to the type of game, the game system 100 may be configured to perform a plurality of types of games therein. However, in a single game device 20, a terminal 21 that provides the same type of game usually belongs.
1, the game apparatus 20A includes four terminals 21A1 to 21A4 that provide a “slot game”, and the game apparatus 20C includes two terminals 21C1 that provide a “pusher game”. Including 21C2, and so on.

In FIG. 1, two or more terminals 21 are always installed in one game apparatus 20, but one game apparatus 20 may include only one terminal 21. Of course, it is within the scope of the present invention.
In the above description, an example in which the game system 100 includes game devices 20A, 20B, 20C,... Corresponding to the types of games has been described, but the present invention describes these game devices 20A, 20B. , 20C,... (In this case, that is, all of the terminals 21) or a part of them does not actively exclude the case where the same type of game is provided.

In the present embodiment, in order for a player to participate in a game developed on the terminal 21, it is required to physically insert a medal (not shown) into a predetermined slot (not shown) of the terminal 21. Depending on the type of game, for example, in the case of a pusher game, the insertion of a medal means acquisition of the qualification for participation as a player, and at the same time leads to the game itself. In addition, a player who achieves a certain score in the game result is usually paid more medals depending on the number of inserted medals.
Thus, in this embodiment, “medal” corresponds to “game medium” in the present invention, but the present invention is not limited to such a form. As described above, the “game medium” is a medium between the game or the terminal 21 and the player, which gives the player eligibility to participate in the game and has achieved a certain result in the game result. Therefore, any medium having such an attribute may be basically a “game medium”. For example, “ideal medal balance (or simply balance)” recorded on an IC card or a prepaid card may also correspond to “game medium”. The “intangible game medium recorded electrically or magnetically” according to the present invention specifically assumes such a case.

As shown in FIG. 1, the determination unit 22 is provided for each game device 20, and determines presence / absence of play for each terminal 21 included in the game device 20. The presence / absence of this play is determined by whether or not the medal has been consumed, including the medal insertion action, for the terminal 21 during the period between the current time and a time point that is a certain time later (here, The meaning of “consumption” of medals in will be described in detail later when the “counting unit 16” is described.) If the period is set to be relatively short, it can be determined whether or not the player is playing the game on the terminal 21 right now.
In particular, in the present embodiment, the determination unit 22 counts not only the consumption of medals inserted during the period but also the number thereof. For example, the determination unit 22A of the game device 20A counts the number of medals inserted within the period in each of the terminals 21A1 to 21A4 as 50, 20, 10, 0, and the like.

  In the present embodiment, the determination unit 22 constitutes a part of each game device 20, but the present invention is not limited to such a form. In short, since it is only necessary for the game system 100 to be able to grasp the presence / absence of play at each terminal 21, an element corresponding to the determination unit 22 is provided in each terminal 21 or the jackpot device 10. May be adopted.

  The communication unit 23 is an interface for performing predetermined communication with the jackpot device 10. The communication contents include the notification of the number of inserted medals for each terminal 21 as a result of the presence / absence of play for each terminal 21 by the determination unit 22 described above, or a medal payment command issued to the terminal 21 winning the jackpot (this is , And the like from the jackpot device 10 to the game device 20 (further, communication from the terminal 21). In the present embodiment, the communication unit 23 mainly operates in response to a communication request command from the jackpot device 10. However, there is no particular problem even if a configuration that allows spontaneous communication from the game apparatus 20 side is adopted. In fact, in the present embodiment, as will be described later, the game apparatus 20 spontaneously starts communication with respect to the number of medals consumed at each terminal 21.

On the other hand, the jackpot device 10 includes a lottery unit 11, a jackpot value memory 12, a winning rate correction value setting unit 13, an operation / display unit 131, a terminal determination unit 14, a communication unit 15, a counting unit 16, and a control unit 19. Contains various elements.
Of these, first, the control unit 19 includes a CPU, RAM, ROM, and the like (not shown), and directly and indirectly applies other various elements so that the entire jackpot device 10 or the entire game system 100 operates in a harmonious manner. Control. In the present embodiment, particularly when the jackpot winning is generated by the lottery unit 11, the control unit 19 issues a medal payment command to the terminal 21 receiving the benefit (this will be described in detail later). . The communication unit 15 is an element to be paired with the communication unit 23 of the game apparatus 20 described above, and is an interface for performing predetermined communication with each game apparatus 20.

  The counting unit 16 counts the number of medals consumed within a predetermined period (hereinafter referred to as “consumed medal number”) for each terminal 21 constituting the game device 20 described above. To do.

Here, the significance of “consumption” of medals will be described in detail.
In the present embodiment, the term “consumption” is temporarily distinguished from the case of “inserting” a medal into the terminal 21 or simply “using” a medal. The “consumption” of medals is regarded as an event that occurs at the time when it can be said that the medal itself inserted into the terminal 21 cannot be recovered by the player and participation in the game is confirmed. Such an event (ie, an event of “consumption”) is identified by the accumulation of one or several specific facts as described below.

Hereinafter, a case where the medal is “consumed” (or at that time) will be described with reference to a specific example.
(I) When the terminal 21 provides a “horse racing game” As described above, the game device 20 of the present embodiment can perform various types of games, but the “consumption” concept is such a game. It is affected according to the type of.
For example, in a horse racing game, the event “consumption” has not yet occurred just by inserting a medal into the terminal 21. In general, in a horse racing game, the inserted medal only has a meaning as a kind of military fund for the player and can be recovered at any time. In such a horse racing game, there are two specific facts (including the medal insertion action, three specific facts): voting on the expected winning horse after the insertion of medals, and no cancellation until the racehorse gate-in time. The medal was “consumed” only after the passage of).

(Ii) When the terminal 21 provides a “pusher game” In the case of a pusher game, insertion of a medal means “consumption” of the medal. In the pusher game, the area affected by the reciprocating motion of the pusher, that is, the act of inserting a medal into the pusher table itself is an act of confirming participation in the game, and the medal cannot be recovered at that time. Because.

(Iii) When the “game medium” is a prepaid card or the like As described above, the “game medium” in the present embodiment is a “medal”, but a specific example thereof is not limited thereto. The concept of “consumption” is influenced according to the kind of such “game media”.
For example, if the “game medium” is a prepaid card or its remaining frequency, there is no room for the act of “inserting a medal” to be a problem, and the terminal based on the act of inserting the prepaid card by the player and the remaining frequency The deduction by 21 etc. is a concrete fact instead. The same can be considered when the “game medium” is a remaining number record account for the player recorded in the center server, etc. (the game system 100 according to the present embodiment uses “center server” Although not provided, it can be easily assumed that the jackpot device 10 has a function corresponding to that.)
Such circumstances relating to the “game medium” are overlapped with the above-described circumstances in which specific facts constituting the “consumption” concept vary depending on the type of game. For example, when enjoying a horse racing game using a prepaid card, the progress of specific facts such as insertion of a prepaid card, voting for an expected winning horse, uncancelled until gate-in, and deduction of the remaining number of prepaid cards This corresponds to “consumption”.

The presence / absence of such “consumption” includes the presence / absence and number of medals inserted in each terminal 21 and the presence / absence of a predetermined operation on the terminal 21 by the control unit 24 (for example, the voting operation of the predicted winning horse in a horse racing game). It is judged comprehensively from various circumstances such as confirmation. The determination itself of whether or not “consumption” has occurred may be performed by the control unit 24 of the game apparatus 20, may be performed by the control unit 19 of the jackpot device 10, or may be performed by the determination unit 22 or the like. May be. In the present embodiment, it is assumed that the presence or absence of “consumption” is determined by the determination unit 22 for convenience of explanation.
In any case, the number of consumed medals counted by the counting unit 16 (particularly, “consumption”) is interpreted in the above meaning or as a term having the above background (claims). The same applies to the terms “consumption” or “number of consumed game media” described in the above.

Then, the counting unit 16 counts the number of medals consumed in this manner as the number of medals consumed within a predetermined period going back from the current time for each terminal 21 constituting the game apparatus 20.
More specifically, first, the “predetermined period” can be set to 60 minutes, for example.
In this case, as a counting method, for example, 60 memories that record the number of medals consumed per minute are prepared as a part of the counting unit 16, and regarding these, every one minute It is possible to employ a method such as obtaining the total number of medals consumed by adding all the values recorded in the 60 memories while being updated. Incidentally, “1 minute” in this case can be adopted as a “period” used as a reference when the determination unit 22 determines the presence / absence of medal consumption (see the description regarding the determination unit 22 described above).
In FIG. 4 or FIG. 5 to be referred to later, an example of the number of consumed medals of each terminal 21 counted by the counting unit 16 is expressed (in FIG. 5, named “consumed medals number”). , See each column in the middle column).

  In addition, in this embodiment, although the counting part 16 comprises a part of jackpot apparatus 10, this invention is not limited to this form. In short, since it is only necessary to be able to grasp the total number of medals consumed by the jackpot device 10, an element corresponding to the counting unit 16 is provided in each game device 20 or each terminal 21. A configuration in which the count result is notified to the jackpot device 10 via the communication units 23 and 15 may be employed.

  The lottery unit 11 determines whether or not to instruct a payment instruction for a medal as a privilege (hereinafter sometimes abbreviated as “privilege medal”) based on a predetermined lottery probability at a predetermined opportunity ( Alternatively, a lottery for the determination is executed.) In the present embodiment, a case where a winning is obtained as a result of the lottery is referred to as “jackpot winning”. This is a privilege given to the player unexpectedly regardless of the result of the game on each terminal 21, and is a return service including a lottery element for the user of the game system 100. The lottery unit 11 has the right to determine whether or not to execute such privilege provision.

Incidentally, the “predetermined opportunity” for the lottery unit 11 to execute the lottery is “when one or more medals are consumed” in the present embodiment. “Consumption” here is synonymous with “consumption” described in detail above. That is, in a certain terminal 21, when it can be said that the player confirms participation in the game and loses the inserted medals (temporarily), a lottery is performed with or without jackpot winning.
In addition, in the present embodiment, the “lottery probability” in the case where such a lottery is executed is directly proportional to the number of medals consumed at the above-mentioned “trigger”.

The jackpot value memory 12 stores the number of privilege medals to be paid when a jackpot winning is made (that is, the jackpot value). Particularly in the present embodiment, this jackpot value is determined according to the total number of medals consumed over each terminal 21, and more specifically, the number of privilege medals increases as the number of medals consumed increases. I will do it. Specifically, for example, the number of medals corresponding to 2% of the total consumed medals is determined as the number of privilege medals, etc. (In this case, if the total consumed medals is 250,000, the jackpot The value is 5000 (= 250,000 × 0.02) In the following, it is a number related to the ratio connecting all the number of medals consumed and the jackpot value (in the present explanation, it happens to be “2%” Is sometimes referred to as "pool rate").
Regardless of the above, depending on circumstances, the jackpot value may always be fixed to a constant value (for example, the above-mentioned 5000).

The winning rate correction value setting unit 13 sets a winning rate correction value corresponding to each game device 20. Here, the winning rate correction value is a value that serves as an index for determining the ease of jackpot winning or the jackpot winning rate.
Specifically, the winning rate correction value is given, for example, in the form shown in FIG. In FIG. 2, the winning rate correction value decreases from the top in order of 1.4, 1.2,. The “coefficient value” in the left column in the figure is a value determined for convenience corresponding to each of these winning rate correction values. In the present embodiment, the larger the winning rate correction value, the easier it is for the game device 20 to win the jackpot than before. This will be described later.
Note that how to use the winning rate correction value in such a specific form will be described later.
In addition, it is each terminal 21 that receives the benefit of jackpot winning that requires a little attention regarding the winning rate correction value according to the present embodiment, but the winning rate correction value described here is different for each terminal 21. Without each game device 20 being defined as one unit.
The set winning rate correction value can be displayed on the display 131A constituting the operation / display unit 131 as corresponding to each game device 20A, 20B,..., For example, as shown in FIG. (Refer to each column in the middle column named “Winning rate correction value” in the figure). The details of FIG. 8 will be described later.

The winning terminal determination unit 14 determines the terminal 21 that will benefit from the jackpot winning by the lottery unit 11. The determination of the terminal 21 is generally performed as follows.
First, based on the presence / absence of play at each terminal 21 determined by the determination unit 22 of the game apparatus 20, it is determined that the terminal is actually being played (that is, there is play or is being played). 21 is selected from all terminals 21. The terminal 21 being played is a candidate who can benefit from winning the jackpot.
Secondly, the “total number of medals for each terminal 21 included in the terminal 21 being played (for example, the number of medals consumed for 60 minutes as described above) related to the terminal 21 being played” “The ratio to the number of medals consumed is calculated. The terminal 21 having a high ratio is more likely to have played a game with a higher price than the other terminals 21. Hereinafter, this ratio will be referred to as “play rate” for convenience.
Thirdly, based on the play rate obtained for each terminal 21 being played and the above-described winning rate correction value determined for the game device 20 to which the terminal 21 belongs, as described above, The jackpot winning rate is determined.
Finally, fourthly, as a result of a lottery according to the jackpot winning rate relating to each terminal 21, a specific terminal 21 is a terminal that benefits from jackpot winning, or the same, but pays a special medal. It is determined as a terminal to be.
The procedure for determining the terminal 21 as described above (including the calculation method of the play rate and the jackpot winning rate) will be described in more detail in the operation description of the game system 100 that starts immediately after.

  The game system 100 according to this embodiment having the above-described configuration operates as described below. Hereinafter, this will be described with reference to FIGS. 3 and subsequent drawings in addition to FIGS. 1 and 2 already referred to. Note that in the game system 100 according to the present embodiment, various processes such as a game execution process in the terminal 21 can be performed in parallel, but in the following, for the sake of simplicity of explanation, the process particularly related to the present invention will be described. Only the explanation will be given.

First, how the processing related to jackpot winning is performed in the present embodiment will be described. Each process described below is executed according to a program stored in the RAM or ROM in the control unit 19 of the central apparatus 10.
In the process related to the jackpot winning, as shown in FIG. 3, whether or not the game apparatus 20 has consumed medals at the terminal 21 in the game apparatus 20 toward the jackpot apparatus 10, Notification is made for some sheets (step S21 in FIG. 3). In this case, the “consumption” of the medal is based on the basic and specific fact that the communication unit 15 of the jackpot device 10 and the communication unit 23 of each game device 20 operate at an appropriate timing and the medal is inserted. The determination unit 22 makes a comprehensive determination as described above.

When the above notification is received, the counting unit 16 of the jackpot device 10 counts the number of medals consumed (step S32 in FIG. 3).
As described above, the counting of the number of medals consumed by the counting unit 16 can be performed for a period of 60 minutes in units of 1 minute, for example. FIG. 4 shows an example of the number of medals consumed for 60 minutes related to the terminals 21A1 to 21A4 constituting the game apparatus 20A. In this figure, it can be seen that the numbers of medals consumed by the terminals 21A1 to 21A4 are 750, 500, 350, and 50, respectively. Moreover, from this figure, it is possible to read the utilization degree of terminal 21A1-21A4 in the latest 60 minutes. For example, with regard to the terminal 21A1, although medals are actively consumed at the beginning of the 60-minute period, almost no medals are consumed in the vicinity of the current time.

  When the number of medals consumed for each terminal 21 is counted in this way, the control unit 19 determines the jackpot value stored in the jackpot value memory 12, that is, the number of privilege medals to be paid when a jackpot winning occurs. Update (step S33 in FIG. 3). Assuming that the number of medals consumed is only as shown in FIG. 4 and the pool rate is 10%, the jackpot value is 165 (= (750 + 500 + 350 + 50) × 0.1). This value is 8 more than the jackpot value 157 one minute before the current time (because the number of medals consumed in the most recent one minute is 0 + 30 + 50 + 0 = 80, see FIG. 4).

  In the present embodiment, the lottery unit determines whether or not the bonus medal is paid, that is, whether or not the bonus medal is paid, when “one or more medals are consumed”. 11 performs the lottery in response to the above notification (step S32 in FIG. 3). In this case, the lottery probability is directly proportional to the number of medals consumed at that time. Here, when the jackpot winning has not occurred, the process related to the jackpot winning process ends (step S34 in FIG. 3; NO to END).

On the other hand, when a jackpot winning has occurred (step S34 in FIG. 3; YES), the jackpot device 10 inquires each game device 20 about whether or not there is a play on the terminal 21 that each of them has ( Step S35 in FIG. 3). Each game apparatus 20 receives this, and each determination part 22 determines the presence or absence of the play in the terminal 21 which belongs to the said game apparatus 20 (step S23 of FIG. 3).
The index for determining the presence / absence of play is the presence / absence of “consumption” of medals as described above. Since FIG. 4 represents the number of medals consumed as described above, this figure can also be used in this case. That is, according to FIG. 4, it can be seen that it is possible to determine that the terminals 21A2 and 21A3 that have consumed medals in the last minute are actually playing. The determination unit 22 notifies the jackpot device 10 of such a determination result.

  When the winning terminal determination unit 14 of the jackpot device 10 receives the notification of the presence / absence of play of each terminal 21, based on this fact and the aforementioned number of consumed medals related to the terminal 21 determined to be playing. Then, the play rate is calculated (step S36 in FIG. 3). As described above, in the present embodiment, the play rate is the “all” consumption related to the terminal 21 being played, of the number of medals consumed for each terminal 21 included in the terminal 21 being played. It is a ratio to the number of medals.

  In FIG. 5, an example of calculating the play rate is visually represented. In this example, first, the terminal 21 that is currently playing is the terminals 21A2 and 21A3 among the terminals 21A1 to A4 constituting the game apparatus 20A, and the terminals 21B1 and 21B2 among the terminals 21B1 to B4 constituting the game apparatus 20B. . The medals consumed for these terminals 21A2, 21A3, 21B1, and 21B2 are 500, 350, 100, and 50, respectively. From the above, the play rates of these terminals 21A2, 21A3, 21B1, and 21B2 are calculated as 500/1000, 350/1000, 100/1000, and 50/1000, respectively (the arrows in the figure indicate the play rates). The origin of the denominator is visually expressed.)

Next, the winning terminal determination unit 14 of the jackpot device 10 determines a jackpot winning rate for each terminal 21 based on the play rate and a predetermined winning rate correction value for each game device 20. (Step S37 in FIG. 3).
Hereinafter, an example of a method of calculating the jackpot winning rate will be described with reference to FIG.

  In the example of FIG. 6, first, the numerator of the play rate for the terminal 21 being played is multiplied by the winning rate correction value. For example, since the winning rate correction value determined for the game device 20B to which the terminals 21B1 and 21B2 belong is 1.2 as shown in FIG. 6, the play rate numerators 100 and 50 of these terminals 21B1 and 21B2 are: They are 120 (= 100 × 1.2) and 60 (= 50 × 1.2), respectively (see FIG. 6). By the way, for the terminals 21A2 and 21A3, the winning rate correction value of the game apparatus 20A is 1.0, so there is no change in the numerator of the play rates of these terminals 21A2 and 21A3. The winning rate correction value is read from the winning rate correction value setting unit 13.

Next, in order to set the sum of jackpot winning rates for all the terminals 21 to 1 in spite of such a change in the numerator of the play rate, the change in the previous numerator is used as the denominator of the play rate of each terminal 21. Add fluctuations increased or decreased by operation. In the example of FIG. 6, as described above, this variation occurs only for the game apparatus 20B, and its value is +30 (= (120-100) + (60-50)). It is added to the denominator of the play rate related to the terminal 21 (see FIG. 6).
The play rate subjected to the above calculation is the jackpot winning rate. In the example of FIG. 6, the jackpot winning rates of the terminals 21A2, 21A3, 21B1, and 21B2 being played are 500/1030, 350/1030, 120/1030, and 60/1030, respectively. According to the percentage display, they are about 48.5%, about 34.0%, about 11.7%, and about 5.8%, respectively.

Next, the winning terminal determination unit 14 of the jackpot device 10 determines a terminal 21 that will benefit from the bonus medal by executing a lottery according to the jackpot winning rate calculated as described above (see FIG. 3 step S38). In response to this, the control unit 19 of the jackpot device 10 issues a privilege medal payment command to the determined terminal 21 (step S39 in FIG. 3). The game apparatus 20 having the terminal 21 pays a bonus medal from the terminal 21 (step S24 in FIG. 3). In this case, the number of privilege medals related to payment follows the jackpot value stored in the jackpot value memory 12 at that time.
In FIG. 1, an example in which the terminal 21B1 belonging to the game apparatus 20B happens to be determined as a terminal that will benefit from the jackpot winning is represented by a dashed arrow shown in FIG. This broken line arrow is drawn so as to sew various elements involved in the payment of the bonus medal described above. That is, the control unit 19 uses the communication units 15 and 23B to pay a privilege medal that matches the jackpot value stored in the jackpot value memory 12 at the terminal 21B1 determined by the winning terminal determination unit 14. The control unit 24B of the game apparatus 20B is instructed, and the terminal 21B1 receives it and pays the privilege medal.

In this case, the payment of the privilege medal can include the following various aspects.
First, simply, the terminal 21 pays medals directly to the player facing it. In this case, as in the case where the player wins the game provided by the terminal 21, the bonus medal is paid directly in the same pocket or the like where the medal is paid at the time of winning. (Herein, “pocket etc.” includes a credit meter and the like.)
Second, when the terminal 21 is a pusher game machine, a bonus medal is inserted into the pusher table of the pusher game machine. In this case, the player does not directly acquire the bonus medal, but the player wins this game because the number of bonus medals inserted into the pusher table increases the game. You will benefit indirectly in the sense. Incidentally, in such a payment mode, it is not necessary that the “game medium” to be paid is limited to a so-called “medal” having a thin circular shape, but it is necessary to be a tangible object.
Thirdly, the terminal 21 executes a notification that temporarily disables the game play on the terminal 21 and prompts the player to directly receive the bonus medal. In this case, as in the case of the first case, the player acquires a privilege medal, but the transfer of the privilege medal is not directly performed in the sense of the terminal 21 to the player, It is performed between the player who has received the notification from the terminal 21 and the administrator of the game system 100 (the above-mentioned “direct reception” assumes such a human interaction). According to such an aspect, for example, the number of privilege medals is very large, and if such a large amount of medals are paid by the method as in the first case, the terminal 21 stops for a long time. Such various troubles can be avoided in advance.
Fourthly, the terminal 21 executes a notification that temporarily disables the game play on the terminal 21 and prompts the administrator of the game system 100 to directly hand over the bonus medal. The meaning is the same as in the third case. Incidentally, the fourth case and the third case can be used in combination.
It should be noted that various methods such as voice and video can be used for the “notification” in the third and fourth cases.

  When the payment of the privilege medal as described above is completed, the jackpot value memory 12 is reset. Here, reset means, for example, firstly when subtracting the number of privilege medals that have been paid from the jackpot value stored in the memory 12, or secondly when setting to a predetermined initial number other than 0, etc. Various things can be considered. Both can be used in some cases. In the second case, when the predetermined initial number is set to 0, if the first case is used together, the jackpot value after reset is 0. Further, an arbitrary setting of the initial number may be possible.

  The above is the processing related to the jackpot winning in this embodiment.

In the present embodiment, on the assumption that such processing is performed, the above-described winning rate correction value can be changed basically at all times. This point will be described below with reference to FIGS.
The winning rate correction value can be changed according to the setting screen as shown in FIG. In FIG. 8, the display 131A is a touch panel type, and when the fingertip of the system administrator touches the minus button 131a and the plus button 131b displayed at predetermined positions on the screen, a game corresponding to the button 131a or 131b. The winning rate correction value for the device 20 can be changed.

In FIG. 8, “actual winning rate” and “total expected winning rate” have the following meanings, respectively.
First, the “actual winning rate” is the ratio of the total number of jackpot wins that have actually occurred for each terminal 21 up to the present time to the total number of jackpot wins. For example, in FIG. 8, if “15%” shown as the actual winning rate of the game apparatus 20A is assumed that jackpot winnings have occurred 100 times in total up to the present time, 15 times of them are the terminals 21A1 to 21A4. It means that it was caused by.
Further, the “total expected winning rate” is the expected jackpot winning rate for each terminal 21 calculated as described with reference to FIG. 5 and FIG. 6 (the meaning of this term will be described later) Is an averaged value for each game device 20 (in this case, “total” in the “total expected winning rate” means that the game device 20 having an expected jackpot winning rate of each terminal 21 is one. It is expressed as a unit.) For example, the overall expected winning rate of the game apparatus 20C is an average of the expected jackpot winning rates of the terminals 21C1 and 21C2 (see FIG. 1). The meaning of “forecast” in the case of “total expected winning rate” will be described later together with the significance of the expected jackpot winning rate.

  FIG. 8 shows that as a result of touching the minus button 131a related to the game apparatus 20B, the previous actual winning rate “42%” has become the overall expected winning rate “26%” ( Of course, from the above definition of both winning rates, a simple comparison of the two is not very meaningful.) More precisely, according to the contact with the minus button 131a (step S11 in FIG. 7; YES), the winning rate correction value for the game apparatus 20B changes (step S112 in FIG. 7), and further accordingly, When the expected jackpot winning rate relating to each terminal 21B1 to 21B4 changes, the overall expected winning rate for the game device 20B changes.

Incidentally, in this case, attention should be paid to the following points, including the significance of the “predicted jackpot winning rate” described above.
First, in the present embodiment, as shown in FIG. 2 that has already been referred to, the winning rate correction value can have five levels. The stage in which the winning rate correction value to be changed is positioned depends on the number of times the minus button 131a and the plus button 131b are touched (that is, the winning rate correction value changes by one step when touched once). Or the like can be adopted.
Secondly, in order to apply the revised winning rate correction value to determine the jackpot winning rate, it is premised that the jackpot winning by the lottery part 11 is premised. "Rate" needs to be defined (see FIGS. 3 and 6 and the description relating thereto). However, as a matter of course, the change point of the winning rate correction value does not always satisfy such a precondition (that is, not necessarily when a jackpot winning occurs). Therefore, the “total expected winning rate” shown in FIG. 8 is set to an appropriate value if the jackpot winning rate is “if the jackpot winning is generated at the present time”, and as a result, averaged for each game device 20. It should be noted that the winning rate is a value that is assumed to be an appropriate value (in this case, “the jackpot winning rate determined as an appropriate value” in this case is the “predicted jackpot winning rate”). ”.) If a jackpot win actually occurs after the change of the winning rate correction value, the jackpot win rate will be recalculated based on the play rate at that time, so the jackpot that should be actually applied in that case The winning rate may always be different from the expected jackpot winning rate at the time of changing the winning rate correction value or the overall expected winning rate.
The “forecast” in the “total expected winning rate” (or “expected jackpot winning rate”) expresses the above-mentioned purpose. It should be noted that the predicted jackpot winning rate and the overall expected winning rate are different from the situation where the jackpot winning is actually occurring due to the nature of the “forecast” value, whether or not the terminal 21 is currently playing. There is no need to be particularly concerned with the distinction. Therefore, as can be read from FIG. 8, these winning rates can be obtained for all terminals 21, unlike FIGS. 5 and 6.

The above description also applies to the remaining game devices 20F, 20C, 20D, and 20E. In FIG. 8, as a result of touching the minus button 131a related to the game device 20F, the previous actual winning rate is “21. % ”Becomes the overall expected winning rate“ 18% ”, and as a result of touching the plus button 131b related to the game devices 20C, 20D, and 20E, the previous actual winning rates“ 6% ”,“ 5% ”and It is expressed that “11%” has become the total expected winning rate “12%”, “10%” and “17%”, respectively. The details or precautions are the same as described above.
Further, as long as the minus button 131a and the plus button 131b related to a certain game device 20 are not touched (step S11 in FIG. 7; NO), the winning rate correction value of the game device 20 is maintained as before. Although it is (step S111 in FIG. 7), the overall expected winning rate of the game device 20 can be changed in accordance with the change of the expected jackpot winning rate and the overall expected winning rate for other game devices 20. There is sex. This is a phenomenon that inevitably occurs in order to set the sum of the expected jackpot winning rates for each terminal 21 to 1 (see FIG. 6 and the description relating thereto).

  In addition, as described above, the overall expected winning rate is obtained by a method of obtaining an expected jackpot winning rate of each terminal 21 and then averaging the winning rates for each game device 20. Without calculating the winning rate, it can be obtained more directly based on the number of medals consumed by each terminal 21 at the time of changing the winning rate correction value. In the present invention, the overall expected winning rate may be determined based on the winning rate correction value after the change and the number of medals consumed at the time of the change. Therefore, the aspect described above is naturally within the scope of the present invention. (The expected jackpot winning rate is calculated from the play rate determined based on the number of medals consumed at the time of changing the winning rate correction value. Therefore, the above-mentioned method is naturally within the scope of the present invention. In.)

According to the game system 100 according to this embodiment having the above-described configuration and operating, the following effects are exhibited.
First, according to the game system 100 of the present embodiment, the phenomenon that the occurrence of jackpot winning is biased with respect to a specific terminal 21 (for example, in FIG. ”Is“ 100% ”or the like), the bias can be corrected. As is clear from the above, the jackpot winning rate of each terminal 21 can be changed by setting the winning rate correction value for each terminal 21 to an appropriate value. It is. In this sense, the game system 100 of the present embodiment provides an environment in which a suitable operation can be realized from an overall viewpoint.

Further, according to the game system 100 of the present embodiment, it is possible to eliminate the distinction between popular models and unpopular models that may occur with respect to each terminal 21 or each game device 20.
As described above, each terminal 21 to each game device 20 according to the present embodiment can be configured to be able to provide various types of games, but in this case, various games themselves are attractive or appealed to customers. Due to the difference in power, there is a case where a terminal 21 always attached by a player and a terminal 21 that does not always have a distinction. Further, even if all the game devices 20 provide the same type of game, the same distinction may occur due to differences in the layout of the game devices 20 in the store (for example, the store In the case of a two-story building, a player often works on a game terminal installed on the first floor, but a game terminal installed on the second floor does not.
However, the administrator of the game system 100 usually does not like the above bias. This is because, as a whole, the game system 100 preferably consumes medals uniformly.
According to the present embodiment, in such a case, by changing the winning rate correction value so that the jackpot winning rate of the terminal 21 corresponding to the unpopular model is higher than the previous value, the distinction is made. It can be solved. In other words, the player is invited to the terminal 21 or the game device 20 which is an unpopular model, with the ease of winning the jackpot winning as an incentive factor.
The game system 100 of the present embodiment also provides an environment in which a suitable operation can be realized from the overall viewpoint in this sense.

Note that the change in the winning rate correction value in each case described above is accompanied by appropriate pressing of the minus button 131a or the plus button 131b shown in FIG. This can be realized by a manual operation by an administrator of the game system 100.
However, the present invention can also automate such manual operation within the scope. For example, when there is a terminal 21 that is poor in appeal and appeal as described above, the number of consumed medals at the terminal 21 should be smaller than that of the other terminals 21. The winning rate correction value for each game device 20 is automatically set so that the jackpot winning rate for such terminal 21 is higher than the previous value. In this case, the transition of the number of consumed medals at each terminal 21 is observed according to a certain rule, or the trigger for executing such automatic setting (for example, the number of consumed medals at a certain terminal 21 is the lowest) If the difference between the value and the number of consumed medals at the terminal 21 having the number of consumed medals closest to the value is a predetermined number or more, etc.) is appropriately determined. Is preferred.
In addition, when such a winning rate correction value is automatically set, some target may be set so that the set value becomes a predetermined value. For example, the winning rate correction value may be automatically set so that the overall expected winning rate for each game device 20 shown in FIG. 8 approaches the same value. In this case, “to approach the same value” means that, for example, in the example of FIG. 8, the total expected winning rate of the six game devices 20A to 20F is about 16.7%, respectively. means. Since 100 [%] is not divisible by 6 in the first place, “to get closer to the same value” described above does not mean just the realization of “the same value” in a strict sense. In the first place, “to get close to the same value” means that the total expected winning rate of the six game devices 20A to 20F is about 16.7% (“evenly divided” for each game device if it cannot be divided). It doesn't mean just that. For example, when the actual winning rate of the game device 20A is 90% and the actual winning rate of the game device 20F is 10%, the former may be set to 70% and the latter to 30%. In the case of an example, it is included in “approaching“ approaching 50% ”.

  Incidentally, in the present embodiment, the winning rate correction value is set so that the overall expected winning rate for a certain game device 20 is increased, and the jackpot winning rate related to the terminal 21 included in the game device 20 is previously set. It can be considered that the winning rate correction value is set so as to be raised from the state of FIG. However, as described above, the actual jackpot winning rate is determined by the number of medals consumed or the play rate of the terminal 21 being played at the time when the jackpot winning is actually generated (FIGS. 5 and 5). 6), as originally intended, the actual jackpot winning rate is not always greater than the jackpot winning rate when the previous jackpot winning occurred. Therefore, in the present embodiment, setting the winning rate correction value so that the overall expected winning rate increases means that the possibility that the jackpot winning rate becomes larger is potentially hidden. But it's more accurate.

As mentioned above, although embodiment which concerns on this invention was described, the game system which concerns on this invention is not limited to the form mentioned above, Various deformation | transformation are possible.
(1) In the above embodiment, the determination unit 22 determines whether or not there is a play based on the presence or absence of “consumption” of medals, but the present invention is not limited to such a form. For example, in some cases, the presence / absence of play is determined based on whether or not a series of game operations (including operations performed by the player on the terminal 21) started with the consumption of medals continues. Also good.
In the above embodiment, the presence / absence of play is determined based on the mere “presence / absence” of medal consumption. In this regard, it is preferable to devise the following measures. That is, in the game system 100 according to the present embodiment, when a jackpot winning is generated in the lottery unit 11, the game system 100 notifies the players throughout the game system 100 of a predetermined effect (for example, with a predetermined sound generation). It can be configured to notify the various light emitting units of the terminal 21 with blinking or the like. This effect is continuously performed for a certain period of time in order to raise the atmosphere of the place and bring out the gorgeousness until the player knows which terminal 21 will benefit from the jackpot winning. However, in this case, there is a possibility that a person who has never played a game until now suddenly consumes a small number of medals and gives up jackpot winning. In particular, when the number of medals consumed by the terminal 21 used for such a purpose happens to be large, the determination of the terminal 21 that will benefit from jackpot winning as in the present embodiment is the magnitude of the play rate. The possibility of occurrence of such an adverse effect is greater (for example, the terminal 21A1 shown in FIG. 4 is used most recently, but the number of medals consumed is the largest). Therefore, there are concerns about the occurrence of such harmful effects.)
Therefore, in order to avoid the occurrence of such a situation, one of the criteria for determining whether or not there is a play is whether or not the number of medals consumed is more than a certain number during a predetermined period going back from the present time. It is good to put. For example, as shown in FIG. 4 that has already been referred to, when the number of medals consumed is 50 or more in the last two minutes, it is determined that the terminal 21 is playing. It is. In this way, immediately after the most recent two minutes ago, an unskilled person who consumes a small number of medals and wants to give up jackpot winning (for example, “in the column relating to terminal 21A1 shown in FIG. 4“ 2)) can be eliminated.

(2) In the above embodiment, the lottery unit 11 performs the lottery for determining whether or not the jackpot is won. “When one or more medals are consumed”, and the lottery probability is However, the present invention is not limited to such a form.
For example, the “predetermined opportunity” is not limited to the consumption of “one” medal, but can be the time when a predetermined number of medals consumed is reached or the consumption of medals It may be a predetermined time (for example, “11:30 pm” or the like) regardless of the presence or absence or the number thereof.
In addition, the “lottery probability” may not depend on the number of medals consumed at each opportunity but may depend on the prescribed number of medals consumed. In addition, in the above embodiment, an example in which the lottery probability is “directly proportional” to the number of medals consumed is described in the above embodiment, but instead of “exponential increase”, Depending on the case, “decrease” or the like may be included.

(3) In the above embodiment, an example of how to determine the play rate is described with reference to FIG. 5, and an example of how to determine the jackpot winning rate is described with reference to FIG. Is not limited to such a form.
For example, in the present embodiment, the play rate is obtained from the number of consumed medals, and the jackpot winning rate (or the expected jackpot winning rate) is obtained from the play rate and the winning rate correction value. Calculation is not always necessary. For example, it is assumed that the consumed medals for terminals 21A2 and 21A3 of game device 20A shown in FIG. 1 are MA2 and MA3, and the consumed medals for terminals 21B1 and 21B2 of game device 20B are MB1 and MB2, respectively. If what is being played at the time of the occurrence of the pot is limited to these terminals 21A2, 21A3, 21B1 and 21B2 (the same situation as shown in FIGS. 5 and 6), these terminals The jackpot winning rate J related to 21A2 can be calculated as J = (MA2 · RA) / (MA2 · RA + MA3 · RA + MB1 · RB + MB2 · RB). Here, RA and RB are winning rate correction values for the game apparatuses 20A and 20B, respectively. Thus, in determining the jackpot winning rate, it is not always necessary to go through the calculation of the “play rate”.

In relation to this, in the above-described embodiment, the way of using the winning rate correction value (see FIG. 2) and how to use the jackpot winning rate (or the expected jackpot winning rate) ( That is, it can be said to be “how to determine the jackpot winning ratio” (see FIG. 6). However, the present invention is not limited to such a form.
For example, in the above embodiment, the winning rate correction value functions as a “magnification value” for changing the size of the numerator of the play rate (that is, it is handled as a multiplication target for the play rate). However, in the present invention, instead of this, the winning rate correction value is handled as an object to be added to the play rate (that is, the jackpot winning rate is obtained by “play rate + winning rate correction value”). ) Is also possible. Alternatively, the winning rate correction value is treated as an exponent part of a term to be multiplied with the play rate (that is, the jackpot winning rate is “play rate × Q ^ (winning rate correction value)” (where Q is an appropriate value) It is also possible to obtain it by a constant).
Even in these cases, if the winning rate correction value is given as shown in FIG. 2, in the former case (in the case of addition), the jackpot winning rate changes more slowly than in the above embodiment, The latter case (in the case of the exponent part) may change more drastically.

  These various methods can be suitably used in combination with the above-described automatic setting of the winning rate correction value so that the overall expected winning rate approaches the same value. For example, in the method of “play rate + winning rate correction value”, in automatically setting the winning rate correction value, basically, the winning rate correction value for each game device 20 is increased and increased. It is relatively easy to achieve the same value for the overall expected winning rate simply by setting to. For example, assuming that each game device 20 includes only one terminal 21 and the play rate of each terminal 21 is PA, PB, PC,... The winning rate is calculated based on PA + RA, PB + RB, PC + RC,... (Where RA, RB, RC,... Are winning rate correction values for each game device 20). As RB, RC,... Each increase, the overall expected winning rate for each terminal 21 or each game device 20 is gradually the same because of the fact that the sum of all events must be 1 (= 100%). I have to approach the value. That is, as the winning rate correction values RA, RB, RC,... Become larger, the overall expected winning rate becomes closer to the same value.
