Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game machine management method and a game machine management apparatus for managing nail adjustment and mode adjustment of a game machine such as a pachinko machine or a pachi-slot machine (slot machine).

[0002]

2. Description of the Related Art Conventionally, in a pachinko parlor, a plurality of pachinko machines or pachislot machines are communicably connected to each other and receive game data output from each pachinko machine, etc., indicating the operating status, and received game data. A gaming machine management apparatus is adopted which processes and manages information according to a predetermined program. This gaming machine management device outputs, for example, the aggregated data of each pachinko machine and the like to the display device and the printing device after the end of business. Further, referring to the game performance data in a predetermined period in the past, for example, by changing the average value of the number of times the variable pattern device is started per unit time, etc., how sales, gross profit, divisor, etc. change It is possible to perform a simulation to analyze whether or not to do it. Then, in the pachinko parlor, referring to the aggregated data and simulation data of the above-mentioned pachinko machines and the like, nail adjustments and the like are performed in order to achieve the target sales and profits.

[0003]

However, in the conventional management method, the data referred to for identifying the pachinko machine or the like requiring nail adjustment is the aggregated data or simulation data of the pachinko machines or the like described above. Therefore, the necessity of adjustment is determined based on the averaged data without considering the skill level of each player, which may result in lack of appropriateness in the management of the gaming machine. For example, in the case of a pachinko machine, the strength with which a ball is fired differs depending on the player, and the trajectory of the ball that is fired also changes depending on the strength of the ball.Therefore, the number of balls paid out from the pachinko machine depends on the player. It will be different. In other words, even with the same pachinko machine, when a lot of players with a relatively high skill level play and a lot of players with a relatively low skill level play a basis for determining whether adjustment is necessary or not. There will be a difference in each of the above data. Therefore,
For example, if the actual payout rate of a pachinko machine (ratio of the total payout balls to the total number of fired balls) is outside the target payout rate range, the pachinko machine is a candidate for adjustment as in the past. The table is not always appropriate because the payout rate also changes depending on the skill level of the player.

The present invention has been made in view of the above circumstances, and makes it possible to determine whether or not adjustment of each gaming machine is necessary based on data in which the skill level of the player is taken into consideration, and more appropriate management than before. An object is to provide a gaming machine management method and a gaming machine management device capable of performing the following.

[0005]

PU) 311 and memory 312. The storage device 32 is composed of a memory, a hard disk, etc.,
The storage device 32 includes a main program 321, a player management database 322, and a game machine management database 3.
23 is stored.

The main program 321 is used in the system control section 31, and is a recording means 321.
a, a calculation unit 321b, an extraction unit 321c, an output unit 321d, and the like.

When the recording means 321a receives the player identification data output from each player identification information acquisition device 20, it refers to the member ID of each player stored in the player management database 322 to play the game. It has a function of specifying a player and writing evaluation target data based on the game data output from each gaming machine into the gaming machine management database 323 stored in the storage device 32 for each gaming machine 10 for each player.

The "evaluation target data" mentioned here means data corresponding to preset evaluation target items. As the evaluation target items, for example, when the gaming machine 10 is a pachinko machine, the number of shot balls (hereinafter referred to as “out”), the payout rate (the ratio of the number of payout balls to the number of shot balls), and the jackpot are excluded. Ball output rate (hereinafter referred to as "base"), average number of starts per unit time (hereinafter referred to as "start"), average number of balls per jackpot (that is, payout per jackpot) The average value of the difference between the number of balls thrown and the number of balls fired, hereinafter referred to as "TY"), the rate of balls thrown during probability change (hereinafter referred to as "A%"), and the like are set. Note that the evaluation target data corresponding to each evaluation target item is calculated by a predetermined calculation formula based on the game data at the time of writing to the gaming machine management database 323, and the obtained value is recorded. .

On the other hand, when the gaming machine 10 is a pachi-slot machine, the number of medals inserted (hereinafter referred to as "out"), the payout rate (the ratio of the number of paid-out medals to the number of medals), and the big hit Rate (hereinafter referred to as "base"), the average value of the number of coins paid out per jackpot (that is, the average value of the difference between the number of medals paid out per jackpot and the number of inserted medals, Below "TY"
Say. ) Etc. are set as evaluation target items.
As in the case of a pachinko machine, the evaluation target data corresponding to each evaluation target item is the gaming machine management database 32.
At the time of writing in 3, the calculated value is calculated based on the game data by a predetermined calculation formula, and the obtained value is recorded.

The calculation means 321b reads out the evaluation target data stored in the gaming machine management database 323, and based on the evaluation target data, a statistical method is used to obtain an evaluation value for each evaluation target item for each gaming machine 10. It has a function to calculate.

The extraction means 321c compares the evaluation value calculated by the calculation means 321b with the simulation data for each evaluation target item of the machine type based on the game performance data in the past predetermined period, and the evaluation value is the above. It has a function of determining whether or not it is within a preset target value range based on the simulation data, and extracting the corresponding gaming machine 10 and the evaluation target item when it is outside the preset target value range.

The output means 321d has a function of outputting the gaming machine 10 and the evaluation target items extracted by the extraction means 321c to a display device or a printing device as the output device 40 as an adjustment candidate base and an adjustment location.

The player management database 322 stores attribute information such as each player's name, address, telephone number, and e-mail address, and player identification data recorded on the card issued to each player. Member IDs for matching are stored for each player. In addition, the game history data of each player (the date and time of the store visit, the game machine and its model played, the game time, the investment amount, the win / loss, the number of coins, etc.) are stored for each player.

The game machine management database 323 includes a game machine-specific data table 323a and a machine-specific data table 3
23b and is comprised. In the gaming machine-specific data table 323a, game performance data for each player is recorded and accumulated for each gaming machine 10, and the gaming machine-specific data table 323 is stored.
In b, game performance data for a predetermined period in the past (eg, past one week) is recorded and accumulated for each model.

Further, in the gaming machine management database 323, there is formed a simulation data table 323c constructed on the basis of the game result data of each machine type stored in the machine type data table 323b. This simulation data table is formed. By utilizing 323c, it is possible to perform a simulation that analyzes how sales, gross profit, divisor, etc. change as the base, start, TY, A%, etc. values increase and decrease. It has become.

The data table 3 for each gaming machine described above
23a, the machine type data table 323b, and the simulation data table 323c are the gaming machine management device 3
By operating an input device (not shown) such as a keyboard connected to 0, it is possible to display or print on a display device or a printing device as the output device 40 at any time.

Next, with reference to the flow chart shown in FIG. 3, an example and operation of the gaming machine management device 30 in the gaming machine management system configured as described above will be described.

The player selects a desired gaming machine 10 from a plurality of gaming machines 10 and inserts the above-mentioned membership card or the like into the player identification information acquisition device 20 installed in the gaming machine 10 to play the game. When the game is started, the player identification information acquisition device 20
Reads the player identification data recorded on the membership card and outputs it to the gaming machine management device 30.

The gaming machine management device 30 has a recording means 321a.
Thus, the player management database 322 is accessed based on the received player identification data, and the matching member ID is extracted from the member IDs of the respective players registered in advance in the player management database 322 (step (S) 101). Since the player identification information acquisition device 20 is installed for each gaming machine 10, each player receives the player identification data output from the player identification information acquisition device 20 as described above, and each player plays the game. The gaming machine 10 to be played can be specified, and by extracting the member ID corresponding to the received player identification data, the player playing the game on the gaming machine 10 can be specified.

On the other hand, when the game is started, the game machine 10 stores game data indicating the operating status of the game machine management device 3
Output to 0. The gaming machine management device 30 has a recording means 321.
By a, the evaluation target data based on the received game data is written in the gaming machine-specific data table 323a formed in the gaming machine management database 323 in association with the member ID extracted in step 101 (S1).
02). As a result, the evaluation target data is recorded and stored for each player for each gaming machine 10.

Through the above steps, for example, when the gaming machine 10 is a pachinko machine, if three players sequentially select the first pachinko machine from a plurality of pachinko machines and play the game, The gaming machine-specific data table 323a of the first pachinko machine is formed, for example, as shown in FIG. This gaming machine-specific data table 323
In a, each player is shown by a member ID, and the evaluation target items “out”, “ball-out rate”, “base”, “start”, “TY” and “A%” are respectively shown. The corresponding evaluation target data for each player is shown.

Here, since the value of "out" indicates the number of shot balls, it can be seen that the larger this value is, the more balls are shot. The value of the "ball-out rate" indicates the ratio of the number of paid-out balls to the number of fired balls. Therefore, with 100% as the boundary, the higher the value, the more the number of paid-out balls relative to the number of fired balls. It can be seen that the obtained number is obtained, and conversely, the smaller the number is, the smaller the number of payout balls is obtained with respect to the number of launched balls. Since the value of "base" indicates the ball output rate excluding the jackpot, the value of the ball output when the jackpot is not in the jackpot can be known from this value. Since the value of “start” indicates the average value of the number of starts per unit time (for example, 10 minutes), it can be seen that the larger the value, the more the variable pattern device is started. Since the value of “TY” shows the average value of the number of balls delivered per jackpot, it can be seen that the larger this value is, the more the number of payout balls was obtained with a smaller number of shot balls during the jackpot. . Since the value of “A%” indicates the winning rate during probability change, the value of the winning rate during probability change can be known from this value. As for the values in the “vehicle average” column, the total value is shown for out and the average value is shown for other evaluation target items.

Then, for example, if the skill level of each player is evaluated by dividing it into five ranks such as "good", "somewhat good", "normal", "somewhat bad", and "bad", the members will be evaluated. It can be said that the skill level of the player with ID “122” belongs to “good” because all the values of the evaluation target items except out are higher than the average value of the units,
The skill level of the player with the member ID “135” belongs to “slightly poor” because the values of “ball throwing rate”, “start” and “TY” are below the average, so it can be said that the member ID is “165”. It can be said that the player's skill level of "belongs to the poor" because all the values of the evaluation target items except the out are lower than the average value of the units.

Thus, in this embodiment, the recording means 32
1a identifies the player based on the player identification data output from the player identification information acquisition device 20, and
The evaluation target data based on the game data output from each gaming machine 10 can be recorded in the gaming machine-specific data table 323a stored in the storage device 32 for each gaming machine 10 and for each player. The skill level of the worker
It can also be evaluated.

Conventionally, the evaluation target data based on the game data output from each gaming machine has only been recorded in a predetermined storage device for each gaming machine without specifying the player. The skill level of the player could not be analyzed and evaluated, and the unit average value for each evaluation target item, that is, the value obtained by averaging the skill level of each player was used as the evaluation value of the game machine. When a plurality of players play one gaming machine, it is normal that there is a difference in skill level among the players, and in the example of this embodiment, the unit average of the first pachinko machine is also averaged. It can be seen that the value has been raised by the performance of the player with the member ID “122” having a significantly higher game level than the other two players. Generally, only a few players have a high skill level, and considering that the majority of players have a lower skill level, it is necessary to position the average value as the evaluation value and adjust the nails as in the past. If the decision is made, there is a possibility that the profit of the player will sometimes be impaired or the profit of the pachinko parlor side will be impaired.

Therefore, in the gaming machine management device 30 according to the present embodiment, the calculating means 321b uses a statistical method based on the evaluation target data stored in the gaming machine-specific data table 323a by the recording means 321a for each gaming machine 10. Then, the evaluation value for each evaluation target item is calculated (S10).
3).

Specifically, the calculating means 321b in the present embodiment calculates, for each gaming machine 10, a value (median) that divides the distribution of the data to be evaluated for each of the items to be evaluated as an evaluation value. . Data table 323 for each gaming machine of the first pachinko machine shown in FIG.
Describing with reference to a, for example, regarding the “ball-out rate” which is one of the evaluation target items, this calculating means 321
According to b, the evaluation target data “100.1” of each player
%, 62.2%, 43.5% "are arranged in ascending or descending order, the central value" 62.2% "is taken as the evaluation value. In addition, when the number of evaluation target data is an even number, for example, the evaluation target data of “ball-out rate” is “100.1
%, 62.2%, 43.5%, 42.0% ", the middle value" 52.85% "of the two central values" 62.2%, 43.5% "is evaluated. The value. Then, the evaluation values are similarly obtained for each of the evaluation target items of "base", "start", "TY" and "A%" other than the "ball payout rate".

FIG. 4B shows the gaming machine-specific data table 323a of the first pachinko machine whose evaluation value has been obtained by the above steps. When the difference in skill level between the players is large and the variation in the evaluation target data for each evaluation target item is large as in the present embodiment, in particular, the evaluation value (base average value) by the conventional arithmetic calculation, It is better to use the evaluation value obtained by the statistical method as the basis of the judgment as in this embodiment.
Depending on the performance of a few players with high skill levels, or the performance of players with extremely low skill levels,
Since the evaluation value is neither raised nor lowered, the current state (adjustment condition) of the gaming machine 10 can be grasped more accurately.

Next, the gaming machine management device 30 has the extraction means 3
21c compares the evaluation value calculated by the calculating means 321b with the simulation data for each evaluation target item of each machine type based on the game performance data in the past predetermined period, and the evaluation value is based on the simulation data. It is determined whether it is within a preset target value range (S104).

More specifically, the gaming machine management database 3
In 23, for example, a model-specific data table 323b as shown in FIG. 5 is formed, and in the model-specific data table 323b, model-specific game performance data in a predetermined past period (for example, one week) (Average game performance data for each same model) is recorded and accumulated. Further, in the gaming machine management database 323, for example, a simulation data table 323c as shown in FIGS. 6 and 7 is formed based on the value shown in the “model average” column of the model-specific data table 323b. Has been done. As described above, the simulation data table 323c is a simulation for analyzing how sales, gross profit, divisor, etc. change as the base, start, TY, A%, etc. values increase and decrease. Since the simulation data table 323c is utilized in advance, a simulation based on the model-based game record data stored in the model-specific data table 323b in the past predetermined period is executed. To be done.

FIG. 6 shows the value of “base”, which is one of the evaluation target items, and FIG. 7 shows the value of “start”, which is one of the evaluation target items. Data table 3
23c, each of which fluctuates "base" and "start"
And the like, and values such as “sales / unit” and “gross profit / unit” indicating sales and gross profit per pachinko machine are the simulation data here. The range of the target value is determined based on these simulation data. For example, the upper limit of gross profit per pachinko machine is “7000
Assuming that "yen" is set and the lower limit is set to "4000 yen" in advance, the range of the target value of "base" is set to "32 to 34" (see FIG. 6), and the range of the target value of "start" is " 5
9 to 61 ”(see FIG. 7).

Then, the extraction means 321c determines, for each item to be evaluated, whether or not the evaluation value is within the range of the target value, and when it is out of the range of the target value, the corresponding gaming machine 10 and the evaluation target Items and are extracted (S105). For example, in the pachinko machine of the first series described above, the evaluation value of "base" is "34" as shown in FIG. Since the evaluation value is “58”, it is outside the range of the above target value.
In this way, it is determined whether or not each evaluation value of "TY" and "A%" is also within the range of each target value. In the present embodiment, the evaluation value of "TY" is outside the range of the target value. And
The evaluation value of "A%" was within the range of the target value. Therefore,
In such a case, the extraction unit 321c extracts the first pachinko machine and each evaluation target item of "start" and "TY".

Here, assuming that the conventional "vehicle average value" is the evaluation value, for example, the "start" vehicle average value is "6".
0 ”(see FIG. 4B), and the range of the target value is“ 59 to 61 ”(see FIG. 7), so it is not an adjustment target. However, since the platform average value is a value raised by the result of one player having a high skill level among the three players as described above, if the nail adjustment is not performed, Amusement machine 10
So, if a normal player whose skill level is not particularly high plays, it is highly likely that it will fall below the target value range, and the winning opening that will trigger the variable pattern device to start than the pachinko parlor planned It is clear that the ball becomes difficult to enter.

The extracting means 321c may be provided with a function of determining how much the evaluation value is above or below the target value range and extracting the evaluation value. Accordingly, when the evaluation value is above or below the range of the target value, it is possible to specifically instruct the degree of nail adjustment according to the degree.

Next, the gaming machine management device 30 outputs the output means 3
21d, the gaming machine 10 and the evaluation target items extracted by the extracting means 321c are output to the output device 40 as an adjustment candidate base and an adjustment point (S106). Output device 4
The output format to 0 can be devised variously and is not limited at all, but for example, as shown in FIG. 4C, the data table 32 for each gaming machine of the corresponding gaming machine 10
In 3a, in order to distinguish the unit number column and the evaluation value column of each evaluation target item from the non-applicable gaming machine 10 or the evaluation target item, the colors of letters and numerical values and the background color are reversed, It is also possible to display on a display device as the output device 40, or to create a list table listing the adjustment candidate bases and adjustment points and output it to the printing device as the output device 40 for printing. As a result, not only the adjustment candidate stand,
It is possible to know the adjustment location concretely and take appropriate measures.

[0042]

As described above, according to the gaming machine management method and the gaming machine management apparatus of the present invention, it is determined whether or not each gaming machine needs to be adjusted based on the data in consideration of the skill level of the player. Therefore, it is possible to perform more appropriate management than before.
