Description

  The present invention relates to an apparatus for managing data of a pachinko gaming machine.

  For example, as described in Patent Document 1 below, data management devices that manage game data of gaming machines such as pachinko gaming machines and slot machines are well known. Such a management device obtains game data such as the number of balls to be thrown in, the number of balls to be paid out and the number of jackpots from the gaming machine side, and by processing this data, significant data such as the number of balls to be played and the number of difference balls are given to the manager create.

  In addition, the data management device described above can also manage the number of pachinko gaming machines that are played separately in the big hit time and the normal time. By taking statistics on the number of balls at the jackpot, it is possible to know whether the number of balls at the jackpot is appropriate, in other words, whether the nail adjustment around the jackpot is appropriate. However, this is only true for pachinko machines that can be played almost certainly up to the maximum round once a big hit is made, such as conventional seven machines.

Therefore, with regard to the second type pachinko gaming machine (so-called “hane”) whose number of rounds played changes every jackpot, the average number of opening of the honey members during one round and the role (central winning device) during one round A management device configured to count the average number of winning balls has been proposed (Patent Document 2).

  By the way, once a big hit has occurred, the seven machines (type 1 gaming machines) that were surely playable up to the maximum round have recently been reviewed and there is a movement to provide multiple jackpots with different maximum number of rounds that can be played . In the future, it is expected that the game will be introduced into the market for seven machines with a game where the jackpot ends in one round at some times, but the jackpot continues to rounds 8 and 15 at other times.

  In the case of a Seven machine, focusing on a specific round, the nail adjustment is performed so that the upper limit number (for example, 10 balls) of the balls will almost certainly win the winning prize opening. Therefore, as described in Patent Document 1, just by knowing the average number of winnings per round and the average number of winnings per jackpot, it is determined whether or not the nail adjustment around the big winning opening is appropriate. It is difficult. Even if it is almost certain that the upper limit number of balls will win the big prize opening, if the nail adjustment is difficult to win moderately, a considerable number of hitting balls will be required until the upper limit number of wins. This is because, if the nail adjustment is extremely easy to win, the number of hitting balls required to win the upper limit is small, and the number of balls to be played per round increases accordingly.

  In addition, regarding the configuration in which the number of rounds that can be played changes, the selection probability for each round (so-called round distribution rate) is determined in the program, but naturally, in a short period such as 2 days a day, there is a variation of each unit. Get out. Therefore, in order to estimate the average number of balls at the jackpot from the number of jackpots and the number of balls at the jackpot, data of at least about one month is required. If this is the case, it will be difficult to adjust the nail as expected at the amusement store because the data population is small when the new platform is replaced. It is also difficult to see if the nails have been adjusted to get the right ball.

  In view of the circumstances as described above, it is an object of the present invention to provide a gaming machine data management device capable of appropriately managing pachinko gaming machines in which the number of rounds that can be played changes for each jackpot. In particular, even if the data population is small, a management device capable of showing an accurate average number of balls played once per jackpot is provided.

Means for Solving the Problems and Effects of the Invention

In order to solve the above-mentioned problems, the present invention provides a plurality of rounds which are the number of unit games that can be performed when a big hit is made, and the number of rounds per jackpot based on a predetermined selection probability of each round number. a gaming machine data management device for managing pachinko machines configured to determine a game data acquisition means for acquiring game data pachinko machine Taigoto, game data game data obtaining means obtains Based on the above, the number of hitting medium hitting balls for deriving the number of balls hitting the jackpot, the number of rounds specifying means for specifying the number of rounds in which the game was played at the big hit of the gaming machine, and the number of rounds specifying means When a player wins a unit game of one round based on the number of rounds to be played and the number of balls in the jackpot that are derived by means of deriving the number of balls in the jackpot Deriving the estimated first average number of appearances, and based on the first average number of appearances and the theoretical average number of rounds of a pachinko machine, the second average number of appearances per jackpot The main feature is that it includes an average number of balls to be derived and a data output means to output the derived second average number of balls.

  Based on the out signal, safe signal and jackpot signal output from the pachinko gaming machine side, the game data acquisition means was paid out during the jackpot and the jackpot hit number representing the number of balls hit during the jackpot It can be configured to count the jackpot / medium safe number representing the number of balls. The jackpot medium hitting ball number deriving means can be configured to derive the number of hitting balls in the jackpot from the difference between the jackpot medium out number and the jackpot medium safe number. Round number specifying means, the number of rounds actually played at the time of the jackpot of the pachinko machine, one or more types of ball data selected from the number of hits in the jackpot, the safe number of jackpots and the number of balls in the jackpot, Or it can comprise as what specifies based on a round signal outputted from a game machine.

  The gaming machine data management device according to the present invention is configured to derive the average number of appearances on the basis of a small gaming unit called the number of rounds. Specifically, in addition to data such as the number of outs during the jackpot and the safe number, it is examined how many rounds the jackpot each jackpot had. Then, it is possible to check how many unit games have been performed in a predetermined period such as one business day. From this result, the number of outs and the number of safes in the jackpot, the number of appearances per round is obtained. In addition, because the design (statistical) average number of rounds is known from the distribution ratio of each number of rounds of gaming machines, the number of balls played per jackpot from the number of balls played per round and the known average number of rounds Find the number. According to such a procedure, since the number of balls to be played is viewed on the basis of one round, it is possible to cancel the influence of the round lottery on the number of balls in which the jackpot is being hit. In addition, since the total number of rounds will surely be greater than the total number of jackpots, the convergence of the number of balls when based on one round is far more than when statistics of the number of balls are taken based on one round of jackpot. Get faster. This is because the number of balls in the jackpot greatly fluctuates due to the effect of the lottery, but the number of balls in a round does not change significantly. In pachinko machines, the number of balls played per round reflects the nail adjustment. Therefore, according to the present invention, it is possible to quickly and highly accurately calculate the average number of balls to be played with a small number of jackpots. Since it is not affected by variations in the number of rounds, it becomes possible to appropriately manage pachinko machines that perform round drawing.

  Moreover, in deriving the average number of balls, since it is necessary to set in advance a distribution ratio of the number of rounds of pachinko gaming machines that are subject to data management, the gaming machine data management device of the present invention has its round distribution ratio It can comprise as a thing provided with a setting means. The round distribution ratio setting means is configured as means for directly describing the round distribution ratio in the program code, or means for creating a file describing the distribution ratio referred to when executing the program.

  In one preferred aspect, the average number of balls deriving means classifies the jackpot according to the number of rounds specified by the round number specifying means, and the average number of balls played per jackpot for each round number (hereinafter referred to as the average number of rounds played). It is configured to include means for deriving the average number of balls by number of rounds for deriving the number of balls) and selecting the average number of balls by number of rounds and the theoretical number of rounds for the pachinko machine round draw Based on the probability, it is configured to derive an average number of balls played per jackpot. According to such a configuration, it is possible to derive the average number of appearances with a small number of processes, and it is also possible to show the distribution of the number of rounds as a list to the manager of the game shop.

  More specifically, the means for deriving the average number of balls is the sum of values obtained by multiplying the average number of balls by number of rounds by the probability of selection of each theoretical number of rounds for the pachinko machine round draw. It can be configured to be derived as an average number of balls that are estimated to be obtained by a player at a time. The theoretical selection probability of each number of rounds can be exemplified by a value determined on a program relating to a round lottery of a pachinko machine or a statistical value of a mechanical distribution device. The distribution device can be arranged on a game board of a pachinko gaming machine.

  In addition, the means for deriving the average number of appearances by number of rounds is determined in advance as the average number of appearances by number of rounds related to the number of rounds that have not occurred when a big hit of a specific number of rounds has not occurred within a predetermined period. It can be configured to substitute the reference value provided. In this way, it is possible to derive a reliable average number of appearances even when no jackpot of a specific number of rounds has occurred.

  In another preferred aspect, the average number of balls deriving means includes the sum of the round numbers specified by the round number specifying means and the sum of the numbers of balls in the jackpot calculated by the jackpot medium number of balls deriving means. From this, the first average number of balls that are estimated to be obtained by a player in one round of unit game is derived, and based on the first average number of balls and the theoretical average number of rounds of a pachinko machine It is comprised so that the 2nd average number of payout concerning one jackpot may be derived | led-out. If it does in this way, it will become possible to show both the average number of appearances on the basis of one round and the average number of appearances on the basis of one jackpot.

  Note that the round number specifying means determines whether the number of balls in the jackpot that was derived by the number of balls in the jackpot is actually determined at the time of the jackpot by determining to which of the range of balls set for each number of rounds belongs. The number of rounds in which a game was played can be specified. Thereby, since the number of rounds can be specified reliably, it contributes to derivation | leading-out of the exact average number of appearance. In addition, the number of rounds can be specified even when no round signal is output from the pachinko gaming machine.

The present invention that solves the problem in another aspect is provided with a plurality of rounds that are the number of unit games that can be performed when a big hit is made, and rounds for each jackpot based on a predetermined selection probability of each round number. A gaming machine data management device for managing pachinko gaming machines configured to determine the number, gaming data acquisition means for acquiring the gaming data of the pachinko gaming machine for each unit, and the game at the time of the big hit of the pachinko gaming machine Deriving game data other than the theoretical jackpot based on the round number identifying means for identifying the number of rounds performed, the game data obtained by the game data obtaining means, and the theoretical jackpot probability of the pachinko gaming machine to one, the game data game data obtaining means obtains the number of rounds that rounds specifying means specified, round lottery pachinko machines The average number of rounds on such theory, or on the basis of the selection probability of the number of each round theoretical according to the round lottery pachinko machines derives the game data in the jackpot theoretical, the derived theoretical Based on the game data other than the jackpot and the theoretical jackpot data, the output rate deriving means for deriving the theoretical output rate of the pachinko gaming machine, and data for outputting the derived output rate And an output means.

  According to the present invention, since the payout rate is derived in consideration of the round distribution rate, even if the number of rounds at the time of the big hit varies due to the round lottery, the statistically reliable output Rate is obtained. By referring to the obtained payout rate, the manager of the game shop can appropriately adjust the nail of the gaming machine.

In a preferred aspect, the game data acquisition means is configured to acquire sales data representing the number of balls lent to the player for each pachinko gaming machine. Furthermore, the game data acquired by the game data acquisition means, the sales data, the theoretical jackpot probability of the pachinko machine, the theoretical average number of rounds for the pachinko machine round lottery, or the round lottery of the pachinko machine Sales data deriving means for deriving corrected sales data when a big jackpot is generated with a theoretical jackpot probability and an average number of rounds based on the selection probability of each theoretical round number, and the sales data and the player obtain There can be provided a quotient deriving means for deriving a quotient that is a ratio with the premium data derived based on the number of the outstanding balls. The division deriving means derives the division based on the game data other than the theoretical jackpot, the game data on the theoretical jackpot, and the corrected sales data. By doing so, it is possible to derive an accurate divisor that is not affected by variations in the number of rounds, so that it is possible to appropriately manage pachinko gaming machines that perform round lottery.

  Also, based on the game data acquired by the game data acquisition means, the jackpot medium number of balls deriving means for deriving the number of balls in the jackpot, the number of rounds specified by the round number specifying means, and the number of balls in the jackpot It is also possible to provide an average number of balls deriving means for deriving an average number of balls that are estimated to be obtained in a predetermined number of rounds based on the number of balls in the jackpot derived by the deriving means. By doing so, it is possible to derive an accurate average number of balls that are not affected by variations in the number of rounds, and therefore it is possible to appropriately manage pachinko machines that perform round lottery.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
FIG. 1 is an overall schematic diagram of a gaming machine system 100. The gaming machine system 100 includes a hall computer 1 (game machine data management device), a plurality of pachinko gaming machines 4, a centralized information display device 6, and a communication network 10 that connects them to each other. On the communication path between the pachinko gaming machine 4 and the hall computer 1, a relay device 2 and a stand-by information display terminal 3 are arranged. The gaming machine system 100 includes the relay device 2 and the table-specific information display terminal 3. One relay device 2 may be provided for a plurality of pachinko gaming machines 4 and may be configured to temporarily or continuously accumulate data from each pachinko gaming machine 4. Furthermore, it is possible to use one of the relay device 2 and the table-specific information display terminal 3 as the other. The concept of communication includes one-way communication from the pachinko gaming machine 4 to the hall computer 1.

  FIG. 2 is a block diagram of the gaming machine system 100 of FIG. The hall computer 1 includes a CPU 101, a ROM 102, a RAM 103, an input / output interface 105 (I / O), and an HDD 104 (hard disk drive), which communicate with each other via a bus. A printer 106, a monitor 107, a mouse / keyboard 108 (input means), and the like are connected via an input / output interface 105. The HDD 104 is allocated with an application program storage area and a game data management area. By summing up (accumulating) the game data sent from the pachinko gaming machine 4 via the relay device 2 or the like, a data file for outputting a form as shown in FIG. And is stored in the game data management area of the HDD 104. A form in which operation data such as a big hit history is described is displayed on the monitor 107 and printed out on the printer 106. The CPU 101 of the hall computer 1 together with the printer 106 and the monitor 107 constitutes a data output means for outputting the contents of the data file.

  The relay device 2 includes a control unit 201 that includes a CPU 211, a ROM 212, a RAM 213, and an input / output interface 214. The table-specific information display terminal 3 includes a control unit 301 including a CPU 311, a ROM 312, a RAM 313, and an input / output interface 314, a display substrate 302, and a liquid crystal display unit 303. The liquid crystal display unit 303 of the table-specific information display terminal 3 displays data such as the number of jackpots, the number of probability fluctuations, the number of jackpots during probability fluctuations, the number of starts from the previous jackpot.

  The hall computer 1, the relay device 2, the stand-by information display terminal 3, the pachinko gaming machine 4, and the centralized information display device 6 are communicably connected via communication networks 10, 11, and 12. The communication networks 10 and 11 can employ serial communication such as RS422 and RS485 standards, for example. However, the present invention is not limited to this. For example, a wireless communication network such as Bluetooth (registered trademark) may be formed. A signal from the card unit 61 is input to the stand-alone information display terminal 3 via the communication network 12a and a signal from the out ball collecting unit 62 via the communication network 12b (see FIGS. 3 and 4). ).

  The game data generated in the pachinko gaming machine 4 is data indicating the operation history of the pachinko gaming machine 4 and is sent to the relay device 2 via the stand-by information display terminal 3. In the gaming machine system 100, a polling / selecting method is employed as the communication method. The hall computer 1 that is the master station asks the relay apparatus 2 that is the slave station whether there is a transmission request (ENQ). The hall computer 1 gives a transmission permission (ENQ) to the relay apparatus 2 that has returned a positive response. Then, the relay apparatus 2 permitted to transmit data transmits data to the hall computer 1. Such a process is sequentially and periodically performed for all the relay apparatuses 2 installed in the amusement store. As a result, the hall computer 1 counts game data output from the pachinko gaming machine 4 side for each pachinko gaming machine 4. The communication between the pachinko gaming machine 4 and the stand-by information display device 3 and the communication between the stand-by information display device 3 and the relay device 2 can be real-time communication.

  Next, FIG. 3 is a block diagram showing the configuration of the pachinko gaming machine 4. The pachinko gaming machine 4 includes a main control board 20, a prize ball control board 31, a display control board 32, and an audio control board 33. The main control board 20 includes a main control circuit 21, an information output circuit 27, and a switch circuit 28. The main control circuit 21 can be constituted by a one-chip microcomputer provided with a CPU 22, a ROM 23, a RAM 24, an input / output interface 25, and the like.

  When a player starts a game and a ball wins a start winning opening (not shown), the winning is detected by the start winning detection unit 29, and a start winning detection signal is sent to the main control circuit 21 via the switch circuit 28. Entered. The main control circuit 21 executes a jackpot lottery process for determining whether or not to generate a jackpot based on the input of the start winning detection signal. In accordance with the lottery result, a control signal is output from the CPU 22 to the display control board 32 and the audio control board 33, and the display unit 36 (liquid crystal display unit) fluctuates and stops, and audio is output from the amplifier / speaker 37. Is done. When a prize ball control signal is input from the CPU 22 of the main control circuit 21 to the prize ball control board 31, a predetermined number of prize balls are discharged from the prize ball device 35. The prize ball substrate 31 and the prize ball device 35 are also used as ball lending machines. That is, when a ball lending request signal is input from the card unit 61 to the prize ball substrate 31, a predetermined number of balls are lent out from the prize ball device. With this ball lending operation, the card unit 61 outputs a ball lending signal corresponding to the number of balls lending to the table-specific information display terminal 3. The ball lending signal may be output from the pachinko gaming machine 4. Moreover, it is also possible to provide an independent ball lending machine that does not communicate with the pachinko gaming machine 4 in place of or together with the card unit 61.

  In the pachinko gaming machine 4, when a ball is won at the start winning opening, the display unit 36 starts to display a variation, and a jackpot is generated when a jackpot symbol defined by a set of three of the same number (character) is confirmed and displayed. It is a model to do. In response to the occurrence of the big win, the special winning opening / closing solenoid 38 (see FIG. 3) is driven to open the special winning opening. During the big hit, a cycle game (unit game) is performed in which the big prize opening is opened until a predetermined time (about 30 seconds) or a fixed number (about 10 balls) wins. If a ball passes through the V zone provided inside the big prize opening during one cycle game, the right to play the cycle game again is granted.

  In the pachinko gaming machine 4, the maximum value of the number of cycle games (referred to as the number of rounds) that can be performed when the jackpot is won varies depending on the round lottery process executed in response to winning the jackpot. Specifically, jackpots of 1 round, 8 rounds or 15 rounds can be generated. Therefore, depending on the number of rounds determined in the round lottery process, the number of balls in the big hit is determined.

  As shown in FIG. 4, a safe signal, an out signal, a ball lending signal, a start signal, and a jackpot signal are output from the pachinko gaming machine 4 side to the table information display terminal 3. Whether the jackpot has occurred in the pachinko gaming machine 4 or not can be identified from the outside of the pachinko gaming machine 4 by switching between the active / inactive of the jackpot signal. Since these signals are transmitted to the stand-alone information display terminal 3 and further to the relay device 2 via the information output circuit 27, the external output terminal 26 and the communication network 12, the hall computer 1 makes an inquiry to the relay device 2. Thus, the gaming state of the pachinko gaming machine 4 is recognized.

  The out signal is a signal that is output in response to a predetermined number of balls being driven into the pachinko gaming machine 4. The out balls are counted by a sensor provided in the out ball collecting unit 62, for example. For example, when 10 balls are detected, the out-ball collecting unit 62 outputs a 1-pulse out signal to the table-specific information display terminal 3. When the stand-by information display terminal 3 acquires an out signal from the pachinko gaming machine 4 side, the hall computer 1 recognizes that ten out balls have been generated in the pachinko gaming machine 4 via the relay device 2. In the present embodiment, the out signal is output from the out ball collecting unit 62, but a configuration in which the out signal is directly output from the pachinko gaming machine 4 is also possible. The safe signal is a signal that is output in response to a predetermined number of balls being paid out from the pachinko gaming machine 4. When the stand-by information display terminal 3 acquires a safe signal from the pachinko gaming machine 4 side, the hall computer 1 recognizes that ten safe balls have been generated in the pachinko gaming machine 4 via the relay device 2. In addition, the case where the safe signal is output from the main control board 20 of the pachinko gaming machine 4 and the case where the safe signal is output from a ball replenishment facility to the pachinko gaming machine 4 can be employed. In the following, the number of balls that have been driven into the pachinko gaming machine 4 will be referred to as the “out” number, and the number of balls that have been paid out from the pachinko gaming machine 4 will be referred to as the “safe number”.

  As shown in the form of FIG. 5, the hall computer 1 records the number of outs and the number of safes of the pachinko gaming machine 4 separately for the big hit time and the normal time. The distinction is based on the out signal, the safe signal, and the jackpot signal that are output from the pachinko gaming machine 4 side. If the jackpot signal is active, the out or safe ball generated at that time can be classified as a jackpot, and if the jackpot signal is inactive, the out ball or safe ball generated at that time is normal. Can be classified as things. Since the form shown in FIG. 5 or the like is output to the monitor 106 or the like, the manager of the game shop can use the form as a guideline for performing nail adjustment or the like on the next day.

  In addition, from the number of safes and outs during jackpots, the number of balls played during jackpots and the average number of balls played per jackpot can be determined. In the gaming machine system 100, the round described above Because it is affected by the lottery process, the average number of hits during jackpots will vary greatly in the short term. However, by deriving the average number of balls per jackpot by the procedure described below, it is possible to derive a highly accurate average number of balls reflecting nail adjustment even with a small number of jackpots.

First, data described in the form shown in FIG. 5 will be described.
<Normal out number>
Number of outs in normal gaming state where the jackpot signal is inactive.
<Normally safe number>
Safe number in normal gaming state where the jackpot signal is inactive.
<Normal number of balls>
(Normal out number)-(Normal medium safe number)
<Base>
((Ordinary medium safe number) / (normal medium out number)) * An index that indicates the number of non-big hit safe numbers defined by 100.
<Start count>
Number of jackpot lottery processes executed by the pachinko machine 4.
<Number of hits during jackpot>
Number of outs during the period when the jackpot signal is active.
<Number of safes in jackpot>
Safe number during the period when the jackpot signal is active.
<Number of balls in jackpot>
(Number of safes in jackpots)-(Number of outs in jackpots)
<Number of rounds>
The number of times that the big hit game was played. In simple terms, the number of times the grand prize opening is opened.

  Since the hall computer 1 periodically makes inquiries to the relay device 2, game data relating to the pachinko gaming machine 4 (ball number data, start number data, jackpot occurrence data) is in the form of time-series data according to the inquiry time. The data is stored in a storage device such as the RAM 103 or the HDD 104. By extracting necessary data from the raw data collected in this way and editing it, a jackpot history data file having contents such as the number of balls described in the form of FIG. 5 is created. There are a case where such processing is performed collectively for all the units in the closing processing after the game shop is closed, and a case where the processing is performed in real time during the business, which is the latter in this embodiment. Then, it is possible to add and display the number of rounds described below on the liquid crystal display unit 303 of the table-specific information display terminal 3 as the history of the day.

  As shown in FIG. 5, the jackpot history of the pachinko gaming machine 4 is recorded together with the time of jackpot occurrence. In the upper and lower data recorded corresponding to one jackpot, the upper row is the total of the period from the previous jackpot to the next jackpot, and the lower row shows the total of one day. As described in this form, the hall computer 1 has a normal medium out number that represents the number of balls that have been struck normally, a normal medium safe number that also represents the number of balls that have been normally dispensed, and the difference between them. Record and record a certain number of normal difference. Similarly, the jackpot / medium out number representing the number of balls hit during the jackpot and the jackpot / medium safe number representing the number of balls paid out during the jackpot are recorded and recorded as history data. The difference between the jackpot / medium-out number and the jackpot / medium-safe number is calculated and recorded as the number of balls in the jackpot (CPU101: jackpot-medium-ball number deriving means).

  Further, the base representing the consumption speed of the ball at the normal time is derived and recorded by dividing the normal medium safe number by the normal medium out number (CPU 101: base deriving means). If the base is large, it means that many balls are paid out during normal times. Therefore, compared to when the base is small, the game can be played for a long time with the same number of balls. It turns out that.

  In addition, as described above, the pachinko gaming machine 4 is a gaming machine in which the number of rounds at the time of the jackpot changes, so the hall computer 1 determines how many rounds of jackpots they have for all jackpots for which the occurrence history has been recorded, It is individually specified and recorded by determining which of the expected payout ranges set for each number of rounds is the number of hitting balls in the jackpot (CPU 101: round number specifying means). In the present embodiment, as shown in FIG. 6, when the number of jackpot hitting balls is 0 to 300, it is determined that one round is a jackpot, and when the number of jackpot hitting balls is 310 to 1300, 8 is set. It is determined that it is a big hit of the round, and when the number of balls in the jackpot is 1310 or more, it is determined that it is a big hit of 15 rounds. The result of this determination is recorded in a field having a round number attribute of the jackpot history data file. Further, instead of the number of hits in the jackpot, the number of rounds per jackpot may be specified from the number of jackpots out or the number of jackpots in the safe. Further, when a round signal indicating the number of rounds is output from the pachinko gaming machine 4, the number of rounds may be specified from the round signal.

  In addition, the update of the jackpot history data file, that is, the creation of a new record based on the occurrence of the jackpot (including the process of deriving the number of balls in the jackpot and the process of determining the number of rounds), the jackpot signal switches from active to inactive This should be done at the opportunity. Then, it is possible to immediately display and output the number of rounds of the previous jackpot on the monitor 107 or the like in the form of the form of FIG. In this way, the number of rounds can be displayed together with the jackpot history on the stand-by information display terminal 3.

  Also, since the distribution ratio (selection probability of each round number) shown in FIG. 6 is a design value in the program of the pachinko gaming machine 4, it is input in advance to the basic data file when a new machine is replaced, and the number of rounds is specified. It is preferable to refer to the basic data file when executing the process. Alternatively, the distribution rate can be directly described in the execution program for the process for specifying the number of rounds. The standard number of balls is the predicted number of balls in each round, which can also be entered in the basic data file in advance when a new stand is replaced, or written directly in the program. You can also. In addition, when a file that records the basic design data of the pachinko gaming machine 4 such as the distribution rate and the jackpot probability is downloaded from a server computer on the Internet site managed by the gaming machine manufacturer, It is good also as a structure which references a download file. In this case, the hall computer 1 is provided with a modem necessary for Internet connection. In addition, the reference | standard number of balls shown in FIG. 6 is data which may be used in the process which estimates the average number of balls at the time of a big hit, as demonstrated below.

  While the number of rounds is specified for all jackpots by the above procedure, an average number-of-rolls data file for obtaining a form as shown in FIG. 7 is created. That is, with respect to the pachinko gaming machine 4, the average number of balls that are estimated to be obtained by a player in a single jackpot or one round of cycle games based on the number of rounds specified in the previous process and the number of balls in the jackpot Is derived. First, as shown in the form of FIG. 7, all jackpots whose history is recorded within the range of one business day of the amusement store are classified according to the number of rounds specified earlier, and the number of jackpots for each round number is a total number of times. Aggregate whether it occurred. For example, in the jackpot history shown in the form of FIG. 5, the jackpot of 1 round occurs 3 times, the jackpot of 8 rounds occurs 0 times, and the jackpot of 15 rounds occurs 4 times. In the jackpot history data file related to the form shown in FIG. 5, the number of times that the jackpot of each round has occurred is searched, and the result is recorded in the number-of-times field of the average payout number data file related to the form shown in FIG. Instead of one business day, the same processing may be performed in a specific time zone such as after 5:00 in the evening. Furthermore, the date of the last nail adjustment may be recorded, and the same processing may be performed across a plurality of business days from that date to derive the data.

  Next, from the actual data, the average hit number (actual data) for the big hits by number of rounds is derived and recorded (CPU 101: average number of appearances by number of rounds means). Specifically, from the data shown in FIG. 5, only the number of jackpot balls out of a specific number of rounds is extracted and summed, and divided by the number of jackpot occurrences of that number of rounds. This process is sequentially performed for all the round numbers.

  By the way, as can be seen from FIG. 5, when the number of jackpot occurrences is small, the number of rounds with zero jackpot occurrences appears. In this case, since it is impossible to derive the average number of balls in the jackpot from the actual data, a predetermined reference value is used as the average number of balls played by the number of rounds related to the number of rounds in which the jackpot has not occurred. to substitute. As the reference value, the reference number of balls described in the basic data file as shown in FIG. 6 can be used. In the basic data file, the standard number of balls played in the jackpot of a specific round is referred to, and this is temporarily substituted as the average number of balls in the jackpot of actual data. Every time a big hit occurs, the form (average number-of-balls data file) update process in FIG. 7 is performed, so that the substitution is temporary. The reference number of balls may be fixed as in the present embodiment, but the average number of balls played by round number obtained from actual data for a certain period in the past (for example, one week) is used as the reference number of balls. May be. Further, as the reference number of balls, an average value of the same model or an average value of the same model in the past may be used.

  As described above, the average number of appearances by round can be derived from the actual data, but even if these are totaled and divided by the average number of rounds, the number of appearances per round is a big hit reflecting the nail adjustment of the table. Hateful. This is because it is strongly influenced by the round distribution. Therefore, after deriving the average number of appearances by number of rounds from actual data and multiplying them by the distribution rate of each round number, the corrected average number of appearances by number of rounds (corrected average number of appearances) The total of the corrected average number of appearances is determined as the average number of appearances (corrected number of appearances) estimated to be obtained by the player once per jackpot. In this way, it is possible to correct the influence of the round lottery on the number of hits in the big hit, and it is possible to know the theoretical average number of hits in the big hit reflecting the nail adjustment of the pachinko gaming machine 4.

  In addition, it can be seen that such a calculation operation standardizes the average number of balls in the jackpot for each round by the round distribution rate. As shown in FIG. 7, the reference average number of balls may be displayed together with the corrected average number of balls. The reference average number of balls can be a value obtained by multiplying the average number of balls by round in a certain period (for example, one week) by the distribution rate.

  Further, as a procedure for estimating the average number of appearances from actual data, the following procedure can also be suitably employed. First, the number of rounds is specified for all jackpots for which history has been recorded. On the other hand, the number of balls in the jackpot is derived from the number of jackpots out and the jackpot medium safe, and the total is obtained. Dividing the total number of hits in the jackpot by the total number of rounds of the jackpot that has occurred can derive the average number of hits that the player is expected to acquire in a one-round cycle game. By multiplying the average number of appearances per round by the average number of rounds estimated from the round lottery program (8 rounds in this embodiment), the average number of appearances per jackpot can be derived. According to this procedure, even if a big hit for a specific number of rounds has not occurred, the actual per game data and the average number of rounds in the design, the nail adjustment specific to the stand is strongly reflected per round. There is an advantage that it is possible to derive the average number of appearances and, in turn, the average number of appearances per jackpot.

  By the way, the average number of balls played per jackpot (corrected number of balls) must be the number of balls played in the average number of rounds when referring to a divide number described later. However, in order to adjust the nails around the winning prize opening, it may be possible to calculate the number of balls that are played when the number of rounds is the same as that of a pachinko gaming machine or the like that does not perform a round lottery (for example, fixed to 15 rounds). . In this way, it becomes possible to adjust the nail around the big winning opening on the same scale regardless of whether or not the model is a lottery for the round lottery, and the data can be easily grasped.

  Next, FIG. 8, FIG. 9, and FIG. 10 show examples of forms that allow a list of data on a plurality of units. Of the jackpot average average number of balls, what is shown as correction data is the value derived in FIG. The sales data can be derived from the number of sales balls counted based on the ball lending signal in FIG. 4 (CPU 101: sales data deriving means). In addition, the quotient is a value indicating the ratio of the number of prize balls to the number of balls sold. According to the size, it is possible to know whether or not the returned ball returned to the player is appropriate. This is significant data. The number of prize balls is the number of balls that the player would have acquired and exchanged for prizes. Specifically, the number of premium balls is the difference between the number of balls sold and the number of balls sold.

  As described so far, the pachinko gaming machine 4 is a gaming machine that performs a round lottery. Therefore, the influence is also exerted on the divide and the nail adjustment of the base is hardly reflected. If the exact divisor is unknown, it is very inconvenient to adjust the nail the next day. Therefore, in the hall computer 1 according to the present invention, as shown in FIG. 8, the number of rounds at the time of jackpot in the round lottery varies from the theoretical average value by correcting the divisor obtained from the actual data. Even in this case, the concept of RD divisor that easily reflects the nail adjustment is introduced.

  Also, as with the divide, it is well known that an index called “depart rate” obtained by dividing the total safe number by the total out number is important in sales activities at amusement stores. The hall computer 1 is also configured to be able to obtain and output such a payout rate. Since the payout rate is essentially affected by the lottery drawing, it is difficult to reflect the nail adjustment. Moreover, as in the case of the pachinko gaming machine 4 described in the present embodiment, in the case of a gaming machine that performs a round lottery, the contribution of the round lottery is superimposed, and the variation in the payout rate for each unit increases. growing. Therefore, as shown in FIG. 11, the hall computer 1 corrects the divisor obtained from the actual data, so that even when the number of rounds at the big hit in the round lottery varies from the theoretical average, It introduces the concept of an RD appearance rate that easily reflects adjustments.

Hereinafter, before explaining the RD payout rate and the RD divisor, a part of the data written in the forms of FIGS. 8 to 11 will be explained.
<Average number of starts>
Number of starts for 1000 out balls
The ratio of the difference in sales to sales as defined by the following formula.
100 * (Normal number of balls) / (Number of balls sold)
<RD out>
The number of outs estimated to occur per jackpot defined by the following formula: 100 * ((probability of jackpot) / (average number of starts)) + (average number of jackpots during jackpot)
<RD safe>
Safe number that is estimated to be generated per jackpot, defined by the following formula 100 * ((probability of jackpot) / (average number of starts)) * ((base) / 100) + (average safe number of jackpot)
<RD appearance rate>
100 * (RD safe) / (RD out)
<RD sales balls>
{(100- (base)) / 100} * {100 * (probability of jackpot) / (average number of starts)} * {(total number of outs) / (number of RD outs)} / {(customer congestion rate / 100)}
<RD division>
10 * {(RD sales balls)-((Total number of outs) * (1- (RD appearance rate)))} / (RD sales balls)

  First, from the total number of outs and the total number of start times, the number of times that the big hit lottery process is executed for a certain number of out balls (1000 in this embodiment) is derived as the average number of start times (CPU 101: average number of start times). Deriving means). The total number of outs is the number of all outs regardless of whether or not the jackpot is hit. The same applies to the total safe number. The total number of start times is the total number of start times from the start of business.

  Next, from the jackpot probability on the program of the pachinko gaming machine 4 and the average number of start times, the number of outs estimated to be averaged in a normal state before the jackpot is generated once (normal average number of outs) Derived (CPU 101: normal time average out number deriving means). Then, referring to the jackpot medium-out number and round number shown in FIG. 5 and the round distribution rate described in the basic data file of FIG. The jackpot average out number) is derived and recorded in the game data file for the form of FIG. 10 (CPU 101: jackpot medium average out number deriving means).

  Specifically, as shown in the form of FIG. 10, the number of 1-round-outs that are the cumulative number of outs in the jackpot determined to be 1 round, and the number of 8 round-outs that are the total number of outs in the jackpot determined to be 8 rounds. The 15 round-out numbers that are the cumulative number of outs in the jackpot determined to be 15 rounds are derived and recorded. Then, the average number of outs for each number of rounds is obtained, and the sum of values obtained by multiplying them by the distribution rate for each number of rounds is set as the average number of outs (correction data) during the jackpot. Furthermore, from the sum of the average average number of outs and the average number of big hits, it is possible to derive the total average number of outs based on one big hit, that is, the number of RD outs normalized by the round distribution rate ( CPU 101: Mean out number deriving means).

  Moreover, you may derive | lead-out average number of big hits by the following methods. That is, the average number of outs per round is derived by dividing the total number of outs during jackpots by the total number of rounds. Multiplying the average number of outs by the average number of rounds in the design of the pachinko gaming machine 4 gives the average number of outs in the jackpot. Note that the numerical values shown in the form output example are not rounded off.

  Next, based on the jackpot probability in design of the pachinko gaming machine 4, the base, and the average number of start times, the safe number that is estimated to be averaged in a normal state until the jackpot is generated once (normal average safe) (CPU 101: normal average safe number deriving means). Then, referring to the number of safes and rounds in the jackpot shown in FIG. 5 and the round distribution rate described in the basic data file in FIG. 6, the number of safes estimated to be generated on average in one jackpot (The jackpot average safe number) is derived and recorded in the game data file for the form of FIG. 10 (CPU 101: jackpot medium average safe number deriving means).

  Specifically, as shown in the form of FIG. 10, a 1-round safe number that is the cumulative safe number in the jackpot determined to be 1 round, and an 8-round safe number that is the cumulative safe number in the jackpot determined to be 8 rounds. The 15-round safe number that is the cumulative safe number in the jackpot determined to be 15 rounds is derived and recorded. And the average safe number according to the number of rounds is obtained, and the sum total of values obtained by multiplying them by the distribution ratio for each round number is set as the average safe number (correction data) during the jackpot. Furthermore, from the sum of the normal average safe number and the jackpot average safe number, the total average safe number based on one jackpot, that is, the RD safe number normalized by the round distribution rate can be derived ( CPU 101: Mean safe number deriving means).

  Moreover, you may derive | lead-out average average number of jackpots with the following methods. That is, the average safe number per round is derived by dividing the total safe number during jackpot by the total number of rounds. Multiplying the average safe number by the average number of rounds in the design of the pachinko gaming machine 4 gives the jackpot average average safe number.

  Finally, from the ratio between the number of RD outs and the number of RD safes derived as described above, the theoretical payout rate of the pachinko gaming machine 4, that is, the RD payout rate normalized by the round distribution rate is obtained. (CPU 101: Departure rate deriving means). The RD out number, the RD safe number, and the RD payout rate derivation result are recorded in the data file for the form shown in FIG. The grounds for calculating the number of outs and safes based on a single jackpot and determining the overall theoretical payout rate are as follows. The theoretical total number of outs and safes is a value obtained by multiplying the number of outs (safe number) based on one jackpot by the number of jackpots estimated to be theoretically a big hit. Since the payout rate is the ratio between the total number of outs and the safe number, dividing both by the theoretical number of jackpots gives the ratio of the number of outs and the safe number based on one jackpot.

  Next, the RD divisor will be described. As a premise for introducing the concept of RD divisor, it is necessary to introduce the concept of RD sales balls. As described with reference to FIG. 4 and the like, the hall computer 1 determines the number of balls lent to the player based on the ball lending signal output from the ball lending device 61 provided in each pachinko gaming machine 4. Record the number of balls sold (number of balls lent) and record. The sales amount shown in FIG. 8 and the like is obtained by multiplying the number of sales balls by the lending amount of one ball. Then, RD sales balls are derived based on the number of sales balls and the arithmetic expression for deriving the RD sales balls described above. Further, based on the above-described arithmetic expression for deriving the RD divisor, the RD divisor is derived (CPU 101: divisor deriving means).

  In this way, the RD divisor and the RD payout rate are the results of correcting the data actually obtained in such a direction that the variation due to the round lottery is reduced, so the nail of the pachinko machine 4 is more than the actual data. It will reflect the adjustment strongly. Therefore, the manager of the amusement store compares the quotient and the yield rate obtained from the actual data with the newly introduced concept, the RD percentile and the RD appearance rate, in accordance with the nail adjustment. It becomes possible to know whether or not a ball has come out, and it becomes possible to properly adjust the nail the next day while referring to those data.

  In the above example, the number of rounds that the pachinko machine 4 can take is discrete, such as 1 round, 8 rounds, and 15 rounds, so it is a simple process that compares the number of balls in the jackpot with the reference value The number of rounds could be specified. However, as shown in the example of the form in FIG. 12, when there are a large number of possible rounds such as 15 types from 1 round to 15 rounds and they are not discrete, the above procedure may not be able to specify the exact number of rounds. growing. This is because the pachinko gaming machine 4 has not only a big winning opening that is opened during the jackpot but also other ordinary winning openings such as a starting winning opening. Furthermore, even if it is said that the upper limit number of balls will almost certainly win the big prize opening, if the nail adjustment is difficult to win moderately, a considerable number of hitting balls will be required until the upper limit number of wins. If the nail adjustment is extremely easy to win, conversely, the number of hits required to win the upper limit is small, and the number of hits per round increases accordingly. If so, it would be difficult to always derive an accurate number of rounds simply by comparing with a reference value. Therefore, in the following, a more preferable process for specifying the number of rounds will be described.

  From the conclusion, the following processing is to obtain a pure safe number during jackpot (medium safe number per jackpot) and to specify the number of rounds based on it. The number of safes per net jackpot is the number of safes obtained by subtracting the contributions of the regular winning mouths other than the big winning mouth from the jackpot medium safe number.

  The form shown in FIG. 12 corresponds to the form shown in FIG. 5 described above. Similarly, the number of normal medium-outs, normal medium-safe numbers, bases, jackpots and outs and jackpots are recorded. Has been. The form of FIG. 12 does not describe the number of jackpots that are safe, but the number of balls in the jackpot is the value obtained by subtracting the number of jackpots out from the jackpot safe number. Equal to what is described. Further, as shown in the round number field, it is understood that jackpots of various round numbers are generated.

  Now, from the jackpot / medium safe number, the contribution of the big winning opening that is opened only when the jackpot is won (the number of net winnings / medium safe), and the contribution of the regular winning mouth that can be won at both the big and non-hit times Are separated from each other by using a base representing the speed of ball consumption at normal times. As mentioned above, the base is an index representing the ratio of the normal safe number and the out number, as defined by ((normally safe number) / (normally normal out number)) * 100. . Therefore, on the premise that the big winning opening is opened only at the time of jackpot, the contribution of the normal winning slot in the jackpot medium safe number is calculated backward from the jackpot medium out number and the base. In other words, if the base number is multiplied by the number of hits in the jackpot, it is estimated how much the normal safe number due to winning in the normal winning slot was paid out during the jackpot of the pachinko gaming machine 4.

  Then, if the ordinary safe number is subtracted from the actual jackpot / medium safe number, the target net jackpot / medium safe number can be derived. Further, the basic data of the pachinko gaming machine 4 that is input in advance in the basic data file shown in FIG. 6 includes the maximum number of winnings allowed for winning in a single winning round and the number of winning prizes. The number of safes per round determined by the number of winning balls (referred to as a one-round theoretical safe number) can be exemplified. Then, when performing the process of specifying the number of rounds, refer to the 1-round theoretical safe number in such a basic data file, and divide the previously derived net safe hit number by the 1-round theoretical safe number. The number of rounds can be specified. Of course, the one-round theoretical safe number itself can be written in the program code for specifying the number of rounds. In addition, as described above, a file in which the basic design data of the pachinko gaming machine 4 such as the theoretical safe number is recorded is downloaded from a server computer on the Internet site managed by the gaming machine manufacturer, and at the time of executing the process of specifying the round number The downloaded file may be referred to.

  Further, the following method can also be adopted. In other words, the number of rounds may be specified by comparing the number of safes per net large with a reference safe number in a preset range for each number of rounds. This is preferable because the number of rounds is not accompanied by a decimal point.

  The identified number of rounds is recorded in a jackpot history data file corresponding to the form of FIG. Using this record, the number of rounds for a plurality of jackpots that have occurred in the past can be displayed on the table-specific information display terminal 3 shown in FIG. As shown in FIG. 13A, the table-specific information display terminal 3 includes operation units 304a and 304b, a liquid crystal display unit 303, and a lamp unit 305. The operation units 304a and 304b include a staff call button, a data display switching button, and the like. As shown in the display example of FIG. 13B, the liquid crystal display unit 303 includes the current start count, today's average number of rounds, today's jackpot count, today's round total, the previous and previous days jackpot count and rounds. Data such as the total, the highest number of jackpots and the total number of rounds, and the number of balls that have received notifications during the period when the probability change continues are displayed. The average number of rounds is the number of rounds obtained by averaging actual data. Also, the graph shows the number of past jackpot start times. The number of jackpot rounds that occurred is displayed in a form corresponding to the number of jackpot start times. By displaying such detailed data, the player can be shown a guide for selecting a vehicle, which is extremely significant as one of the services of a game store.

  In addition, data similar to the table-specific information display terminal 3 may be displayed on the central information display device 6. The centralized information display device 6 can display data for all or a plurality of units in the amusement store.

  Note that the procedure for specifying the number of rounds is based on the premise that a ball that has not won a normal winning prize will win a big winning prize at the time of a big win. However, there may be a case in which a grand prize opening is provided near the upper part of the game board surface, and a ball that could not win in the big prize opening will win the normal prize opening. In such a situation, the following procedure can be suitably employed. First, the normal safe number is derived by multiplying the corrected jackpot medium number out by subtracting the theoretical number of winnings from the jackpot out number from the base. Then, a net jackpot medium safe number is derived from the normal safe number and the jackpot medium safe number.

  In the embodiment described above, the processing for specifying the number of rounds is performed exclusively for the hall computer 1, but part or all of such processing performed by the hall computer 1 is performed by the stand-alone information display terminal 3. The hall computer 1 can be configured to acquire only the result.

  Moreover, although the lottery (lottery) by electrical processing was shown as an example of a round lottery, the following another example can also be considered. For example, a distribution device (so-called Kroon) with three (multiple) ball winning holes inside is provided on the game board so that when the jackpot is generated, only one ball is awarded to the distribution device. To do. Then, the number of jackpot rounds is changed by a physical sorting operation inside the sorting device. There is a one-to-one correspondence between the winning opening in the distribution device and the number of rounds.

  Further, the present invention may be applied to other gaming machines such as slot machines. Moreover, although this embodiment has been described by taking the management of so-called seven machines as an example, it goes without saying that the management device of the present invention may be applied to the management of so-called honey (second-type pachinko gaming machines). is there. In addition, the present invention may be applied to a management device for a pachinko gaming machine in which a probability variation state or a time reduction state occurs after the end of one big hit. The probability variation state refers to a state in which the jackpot probability is different from the normal state. The time reduction state refers to a state in which the number of jackpot lottery processes executed per unit time is controlled to be higher than in the normal state. When considering such special conditions, the data for the jackpot such as the corrected average payout rate is the data until the big hit, the data during the big hit, and the data associated with the special condition such as probability change. Will be included.
