The present invention relates to a system detecting fraud in a game in a casino, or error or fraud at the time of betting or settlement of chips.
In a casino or the like, attempts have been made to prevent various frauds. The casino includes a surveillance camera for surveilling the fraud, and prevents a fraud by detecting a fraud in a game, or a fraud due to collection or paying of chips, different from a win or lose result, from an image obtained by the surveillance camera.
On the other hand, it is proposed that a wireless IC (RFID) tag is applied to each of the chips in order to recognize the numbers or the total amount of bet chips, and thus, the amount of chips is recognized.
In a card game monitoring system described in WO 2015/107902 A, whether or not chips placed on a gaming table are collected or paid as a win or lose result is determined by performing image analysis with respect to the movement of the chip, and thus, fraud monitoring is performed.
An object of the invention is to provide a novel system managing a game in a casino.
One aspect of the invention is a game management system managing a casino game performed in a plurality of tables in casino facilities, the system including: a camera obtaining an image by capturing bet gaming tokens; an information processing device specifying a betting amount on the basis of the type and the number of gaming tokens in the image by specifying a betting target on the basis of a position of the gaming token in the image; a game result determination device determining a game result of the casino game; a calculation device calculating a profit of a casino manager for each table and each game of the plurality of tables, on the basis of the betting target, the betting amount, and the game result; and a recording apparatus recording the profit.
The foregoing and other objects, features, aspects and advantages of the exemplary embodiments will become more apparent from the following detailed description of the exemplary embodiments when taken in conjunction with the accompanying drawings.
In a casino such as a casino, highly stacked chips are placed on a gaming table, and thus, there is a problem in that a total amount of the chips cannot be accurately read by an IC tag reading device provided under the gaming table. If the sensitivity of the reading device is heightened, chips placed at other positions (win or lose depends on the position) may be added, and thus, there is a problem in that the total amount of chips at each position cannot be recognized. In addition, in image capturing of a camera, there is a problem in that the total amount of chips cannot be recognized because a blind spot is formed according to a viewing angle of the camera, or entering into a shadow caused by overlap.
In addition, if cards are slanted by “card squeegee” (behavior of bending a face-down card to enjoying a rank of the card little by little) or the like which is frequently performed by players in a baccarat game, there is a problem in that ranks and suits of cards cannot be determined through image analysis using cameras.
In addition, fraud in the gaming table is further more sophisticated, and thus, there is a new problem in that fraud by an advanced betting method which cannot be found through simple detection of largeness or the like in the winning amount in the gaming table cannot be detected by the camera or by tracking the winning amount. In addition, fraud according to conspiracy of a dealer and a player is not sufficiently prevented in the related art.
In order to solve the above-described problems, in a first embodiment, a fraud detection system in a casino having a plurality of gaming tables is configured to include a game recording apparatus which records a progress of a game played in the gaming table including a dealer and a player as an image through a camera, an image analyzing apparatus which performs image analysis on the image of the recorded progress of the game, a card distribution device which determines a win or lose result of each game in the gaming table, and a control device which detects fraud practiced in the gaming table by using a result of the image analysis by the image analyzing apparatus and a win or lose result determined by the card distribution device.

In addition, the control device has an artificial intelligence utilizing type structure or a deep learning structure capable of performing comparison calculation of match or mismatch between the total input amount of the cash according to the input by the dealer in the gaming table for which the dealer is responsible and the total amount of the cash according to the result of the image analysis by the image analyzing apparatus.
According to the fraud detection system of the embodiment, although the cards are slanted by “card squeegee” frequently performed by players in a baccarat game or the like, the rank and suit of the cards can be determined by image analysis, so that the total amount of chips being overlapped or being in a blind spot together with the positions can be recognized. In addition, fraud at the time of exchanging cash and chips can be detected.
Hereinafter, an overview of the fraud detection system in the casino having a plurality of the gaming tables in the first embodiment will be described more in detail.
The fraud detection system is configured to further include a control device 14 which compares the actual rank of the cards according to the result of the image analysis by the image analyzing apparatus 12 and the win or lose result determined by the card distribution device 3 to detect fraud (for example, mismatch between a sum of ranks of distributed cards and a win or lose result) performed in the gaming table 4. The card distribution device 3 has a structure capable of reading rank (A, 2 to 10, J, Q, K) and suit (heart, spade, or the like) of the card C manually distributed by the dealer 5. The control device 14 has a structure capable of determining match or mismatch by checking information on rank and suit obtained from the image (captured by using the camera 2) of each card distributed in the gaming table 4 by the image analyzing apparatus 12 (using artificial intelligence) and information on rank and suit read by the card distribution device 3. In this fraud detection system, each of the image analyzing apparatus 12 and the control device 14 has a structure including a computer configured with an integrated or plural components, a program, and a memory in a complex manner.
Each of the image analyzing apparatus 12 and the control device 14 has an artificial intelligence utilizing type structure or a deep learning structure where, with respect to even a card C which is distributed in the gaming table 4 and is folded or stained by the player 6, information on rank of the card can be obtained. As illustrated in
The control device 14 having an artificial intelligence utilizing type structure or a deep learning structure can recognize, through the camera 2 and the image analyzing apparatus 12, the position (player, banker, or pair) of the betting area 8 on which the player 6 wagers the chip 9 and the types (different amount values are designated to different colors of the chips 9) and the number of the wagered chips 9. In many case, the chips 9 are not aligned and stacked in the vertical direction, but as illustrated in
The control device 14 is capable of performing analysis and recognition of the total amount of the chips 9 in the chip tray 17 of the dealer 5 of the gaming table 4 by using the image analyzing apparatus 12 and is capable of performing comparison calculation according to the win or lose result of the game as to whether or not the total amount of the chips 9 in the chip tray 17 is increased or decreased according to the amount of the collection of the lost chips 9 wagered by the players 6 and the redemption (9W) of the winning chips of the winning player 6W after the end of the game and the settlement. Although the total amount of the chips 9 in the chip tray 17 are always checked by means of RFID or the like, whether or not the increased or decreased amount is correct is performed by the control device 14 allowing the image analyzing apparatus 12 to perform image analysis of the progress of the game. An artificial intelligence utilizing type structure or a deep learning structure is used for these configurations.
In this example, since fraud or error is detected based on the information of the win or lose result of the game, information as to what position (player, banker, or pair) of the betting area 8 how many and what type of the chips 9 are wagered on, and the increased/decreased amount of the chips 9 in the chip tray 17 after the collection of the lost chips and the redemption for the winning chips 9, fraud or error can be detected although the recognition of the movement of the chips 9 after the end of the game, that is, the movement of the wagered chips 9 toward the player side or the movement toward the dealer side is not performed.
Herein, for example, in the baccarat, the win or lose result of the game can be determined in accordance with the rule of the baccarat by reading the rank of a card C fed out in the game in the card distribution device 3. In addition, the win or lose result of the game can be determined by capturing an image of the gaming table 4 by using the camera 2, analyzing the image by using the image analyzing apparatus 12, and matching the analysis result with the game rule by using the control device 14. In this case, the camera 2, the image analyzing apparatus 12, and the control device 14 constitute a win/lose result determining apparatus. Information on the players at each play position 7 and information as to what position (player, banker, or pair) of the betting area 8 how many and what type of the chips 9 are wagered on can be obtained by capturing an image of the chips 9 placed on the betting area 8 by using the camera 2 and analyzing the image at each play position 7 by using the image analyzing apparatus 12.
In addition, the increased/decreased amount of the chips 9 in the chip tray 17 before and after the collection of the lost chips 9 and the redemption for the winning chips 9 can be calculated by comparing total amount of the chips 9 in the chip tray 17 before the collection of the lost chips 9 and the redemption for the winning chips 9 and the total amount of the chips 9 in the chip tray 17 after the collection of the lost chips 9 and the redemption for the winning chips 9. The total amount of the chips 9 in the chip tray 17 before the collection of the lost chips 9 and the redemption for the winning chips 9 and the total amount of the chips 9 in the chip tray 17 after the collection of the lost chips 9 and the redemption for the winning chips 9 can be detected by capturing an image of the chip tray 17 containing the chips 9 by using the camera 2 and analyzing the image by using the image analyzing apparatus 12. In addition, the total amount of the chips 9 contained in the chip tray 17 may be detected by burying RFIDs representing the amount is in the chips 9 and providing an RFID reader to the chip tray 17.
For example, the total amount of the chips 9 in the chip tray 17 before the start of the game is denoted by Bb, and the total amount of the chips 9 in the chip tray 17 after the end of the game and the end of the collection of the lost chips and the redemption of the winning chip is denoted by Ba. In addition, in the game, the total amount of the entire play positions 7 in the player area where the chips 9 are wagered is denoted by bp, the total amount of the entire play positions 7 in the banker area where the chips 9 are wagered is denoted by bb, and the total amount of the entire play positions 7 in the tie area where the chips 9 are wagered is denoted by bt. For example, in the case where the win or lose result of the game is banker win, Ba−Bb=bp−bb+bt needs to be satisfied. Alternatively, the total amount Ba of the chips 9 in the chip tray 17 after the end of the game needs to be (Bb+bp−bb+bt). In the case where the above condition is not satisfied, it may be determined that fraud or mistake occurs in the collection of the chips or the redemption for the chips.
In addition, the redemption for the chip 9W to the wining player 6W is performed by using the chips 9 in the redemption chip tray 172, and the image analyzing apparatus 12 and the control device 14 can secure an enough time to recognize the actual total amount of the chips 9 in the collection chip tray 171 after the collection.
The gaming table 4 is provided with a discard area 41 and/or a discard slot 42 for discarding the cards C used in the game. When the game is ended, the cards C used in the game are collected and discarded in the discard area 41 or the discard slot 42 on the gaming table 4.
The gaming table 4 is further provided with a marker 43 indicating win or lose of the game.
In this manner, in the embodiment, the control device 14 calculates balance in chips from the amount of the betting chips on the gaming table 4 for each game and the win or lose result of the game and verifies the increased amount of the balance of the chips in the chip tray 17 after the game. If the difference is detected in the verification, the control device 14 issues caution or adds the record indicating this message to the record of the video captured by the camera 2. A casino manager can investigate the cause of the difference by checking the video.
In the embodiment, the fraud detection system performs addition/subtraction calculation of the increased/decreased amount of the chips in the game calculated from the position, type, and number of the chips 9 wagered by all the players 6 in the game and the win or lose result of the game obtained from the win/lose result determining apparatus from the total amount of the chips 9 in the chip tray 17 before the settlement of each game and compares the correct total amount of the chips 9 in the chip tray 17 after the end of the game and the settlement and the actual total amount of the chips 9 in the chip tray 17 at the time of the end of the game obtained through the image analyzing apparatus 12 to determine whether or not there is difference between the correct total amount and the actual total amount.
The control device 14 recognizes the position, type, and number of the chips wagered by each player through the image analyzing apparatus 12, recognizes the actual total amount of the chips in the chip tray at the time when the collection of all the amount of the lost chips wagered by each player is ended, compares the correct total amount of the chips 9 in the chip tray 17 added with the increased amount of the chips in the chip tray 17 in the game from the position, type, and number of the chips wagered by the lost player from the total amount of the chips in the chip tray before the settlement of each game and the actual total amount of the chips 9 in the chip tray 17 to determine whether or not there is difference between the correct total amount and the actual total amount.
In the case where the control device 14 compares the correct total amount of the chips 9 in the chip tray 17 added with the increased amount of the chips in the chip tray 17 in the game from the position, type, and number of the chips 9 wagered by the lost player from the total amount of the chips 9 in the chip tray 17 before the settlement of each game and the actual total amount of the chips 9 in the chip tray 17 and determines that there is no difference between the correct total amount and the actual total amount and the control device compares the correct total amount of the chips in the chip tray 17 after the end of the game and the settlement and the actual total amount of the chips 9 in the chip tray 17 obtained through the image analyzing apparatus 12 at the time of the end of the game and determines that there is difference between the correct total amount and the actual total amount, the control device determines a mistake in payment and generates a payment mistake signal indicating the mistake in payment.
The chip tray 17 is provided with a collection chip tray 171 where the chips 9 wagered by the lost player are collected and temporarily stored. The image analyzing apparatus 12 compares the correct total amount of the chips 9 in the collection chip tray 171 added with the increased amount of the chips 9 in the game calculated from the position, type, and number of the chips 9L wagered by the lost player and the actual total amount of the chips 9 in the collection chip tray 171 to determine whether or not there is difference between the correct total amount and the actual total amount.
When the control device 14 determines that there is difference that the recognized actual total amount of the chips 9 in the chip tray 17 of the dealer 5 of the gaming table 4 does not match with the increased/decreased amount of the chips calculated from the amount of the chips wagered by all the players and the win or lose result of the game, the game recording apparatus 11 may allocate indexes or time points to the acquired images or may reproduce the images specified with a collection scene or a redemption scene of the chips 9 so that the record of the game where the difference occurs can be analyzed in the game recording apparatus 11.
In this manner, the control device 14 acquires the total amount of the chips in the chip tray 17 after the end of the game and the settlement through the image analyzing apparatus 12, and in this case, the determination after the settlement is performed at any one of the times 1) to 4) as follows: 1) the time when redemption for the winning chips 9 is ended; 2) the time when the cards C used in the game are collected to be discarded into a discard area 41 or a discard slot 42 of the table; 3) the time when a predetermined button attached to the win/lose result determining apparatus is pushed; and 4) the time when a marker 43 representing win or lose is returned to an initial state.
In addition, the control device 14 has an artificial intelligence utilizing type structure or a deep learning structure capable of extracting a strange situation (set by the casino side) by recognizing the position (position of player, banker, or pair wagered) and amount (type and number) of the chips wagered on each play position 7 of the gaming table 4, comparing the history of win and lose of each player 6 obtained from win or lose result of each game and the amount of the acquired chips (winning amount) and the statistical data of a large number of previous games (big data). Typically, the control device 14 has an artificial intelligence utilizing type structure or a deep learning structure, where, in the case where an winning amount of a certain amount (one million dollars) or more occurs and the state that the amount of betting chips at the lose time is small and the amount of betting chips at the win time is large at a play position 7 of a certain gaming table 4 continues several games, the state can be extracted as a strange situation by comparing the state and the statistical data (big data or the like) of previous games.
In addition, the control device 14 (integrated with the image analyzing apparatus 12) of the fraud detection system has a structure capable of extracting a strange situation or specifying individual player 6 at the play position 7 which the player wins a predetermined amount or more. With respect to the specifying of the player 6, in the image analyzing apparatus 12, an image of a face is obtained by extraction of feature points, and identification number (ID) is provided to specify the player. In addition, the control device 14 has a caution function of informing about the existence of the specified player in another gaming table when the specified player 6 departs and arrives at the other gaming table. More specifically, a pit manger managing each gaming table 4 or each table manager (or a dealer) is informed, so that the strange situation can be further prevented.
In addition, control device 14 is provided with database storing history of exchange of cash K and the chips 9. By referring to the database in unit of a predetermined time or a day, the control device performs comparison determination as to whether or not the recognized amount of the chips 9 in the chip tray 17 of the dealer 5 of the gaming table 4 is increased or decreased according to the paid amount of the chips 9 corresponding to the exchanged cash K or the total amount of the paid amount of the cash K corresponding to the exchanged chips 9.
In addition, in the above-described example, the history of win and lose and the amount of the acquired chips (winning amount) for each play position 7 may be surveilled without specifying individual player 6. In this case, if each player 6 leaves the seat, the player 6 cannot be tracked. However, the strange situation where the amount of betting chips at the lose time at the specified play position 7 of one game table 4 is small and the state that the amount of betting chips at the win time is large continues for several games can be detected. Next, in the case where such a play position 7 is detected, it is suspected that there is fraud or error at the play position 7. Next, by verifying the video obtained by capturing an image of the play position 7, the fraud or error can be found.
More specifically, the camera 2 is installed to capture at least an image of the chips 9 placed on the betting area 8 of the gaming table 4. The image analyzing apparatus 12 analyzes the image captured by the camera 2 to detect which of the positions “player”, “banker”, and “tie” of the betting area 8 the chips are placed on for each user position 7 and the amount of the placed chips. In addition, the card distribution device 3 also functions as a win/lose result determining apparatus to determine the win or lose result of the game. The control device 14 records (surveils) the history of win and lose and the amount of the acquired chips (acquired amount of chips) for each play position 7 based on the position (player, banker, or tie) of the betting area 8 on which the chips 9 are placed and the win or lose result of the game. In addition, any one of the history of win and lose and the acquired amount of chips may be recorded. In the case of a strange situation (set by the casino side) that the history of win and lose and/or the history of the acquired amount of chips are strange in comparison with the statistical data of a large number of previous games (big data), the control device 14 specifies the player position 7 as a play position where fraud is suspected to occur.
In the case where fraud is suspected to occur at a certain player position 7, the fraud detection system may generate alarm (light, sound, or vibration) so that at least dealer can perceive at this time. Therefore, at least at this moment, by stopping the subsequent game or the like, it is possible to prevent the fraud from continuously occurring. In addition, information indicating that fraud is suspected to occur may be added to the image captured and recorded by the camera 2. Therefore, by checking video, it is possible to find a cause of the suspicion of the fraud.
The fraud detection system in the casino having the gaming table according to the embodiment further has a function of performing inspection at the time of exchange of cash and chips which is frequently performed in the gaming table 4. In the casino such as a casino, before a game, the player 6 exchanges money (cash or the like) and gaming chips at a predetermined cashier cage. When the player 6 spends all chips, the player may exchange cash and chips 9 on the gaming table (baccarat table or the like) to continuously do the game without leaving the seat from the gaming table 4. However, at the point, there is a chance of fraud between the dealer 5 and the player. On the gaming table (baccarat table or the like), the exchange of the cash and the chip 9 needs to be performed when the game is not in progress. In order to determine the win or lose of the game, the card distribution device 3 can detect card dealing start and dealing end (time of determining the win or lose). Therefore, the card distribution device 3 detects a situation other than card distributing (dealing), and the control device 14 detects the exchange of the cash and the chips 9 in the gaming table 4 in the situation other than the card dealing (illustrated in
The control device 14 can recognize the number and amount of cash K by performing the image analysis on the surface of the cash. In addition, in the gaming table 4, whether or not the cash K in exchange for the chips 9 is genuine is performed by irradiating the cash with black light to detect a genuine mark G of the cash. As illustrated in
The control device 14 has an artificial intelligence utilizing type structure or a deep learning structure capable of performing comparison calculation as to whether or not the total amount of the chips 9 in the chip tray 17 of the dealer 5 of the gaming table 4 is increased or decreased according to the paid amount of the chips corresponding to the exchanged cash after the exchange of cash and chips and the settlement. The case where the total amount of the chips 9 in the chip tray 17 of the dealer 5 is always checked by the RFID or the like of the chips 9 in advance may be considered. In addition, the total amount of the chips 9 contained in the chip tray 17 can be detected by capturing an image of the chip tray 17 containing the chips 9 by using the camera 2 and analyzing the image by using the image analyzing apparatus 12.
In addition, the control device 14 verifies match between the increase or decrease of the amount of the chips 9 in the chip tray 17 and the exchanged amount of the chips according to the result of the image analysis of the gaming table 4 before and after the exchange of cash and chips. The paid amount of the cash may be input to the control device 14 by the dealer 5 through key input or the like. The paid amount of the cash may be specified by the camera 2 capturing an image of the gaming table 4 where the cash is being paid and by the image analyzing apparatus 12 analyzing the image.
As described above, the control device 14 determines whether or not the decreased amount of the chips 9 in the chip tray 17 due to the exchange of cash and chips matches with the amount of the cash paid to the dealer 5 by the player 6. In addition, the control device 14 is an intelligence control device and has an artificial intelligence utilizing type structure or a deep learning structure capable of performing comparison calculation of match or mismatch between the input amount (typically, obtained by key input or the like) of the cash by the dealer 5 and the calculated amount of the cash obtained from the result of the image analysis by the image analyzing apparatus 12 after the exchange of cash and chips and the settlement.
In addition, the control device 14 has an artificial intelligence utilizing type structure or a deep learning structure capable of performing comparison calculation of match or mismatch between the total input amount of the cash according to the input by the dealer in the gaming table 4 for which the dealer is responsible and the total amount of the cash according to the result of the image analysis by the image analyzing apparatus 12.
The control device 14 performs comparison determination as to whether or not the recognized amount of the chips 9 in the chip tray 17 of the dealer 5 of the gaming table 4 is increased or decreased according to the paid amount of the chips 9 corresponding to the exchanged cash or the paid amount of the cash corresponding to the exchanged chips 9 after the exchange of the cash and the chips 9.

Such a technique is a technique of performing image recognition on a captured image to recognize an object included in the image. Particularly, in recent years, object recognition at high accuracy is performed by using a deep learning technique utilizing a multilayered neutral network. In the deep learning technique, generally, layers covering multiple stages are overlapped in intermediate layers between an input layer and an output layer of the neutral network, so that the object is recognized at high accuracy. In the deep learning technique, particularly, a convolution neutral network has drawn attention because the convolution neutral network has higher performance than the object recognition based on image feature amounts in the related art.
In the convolution neutral network, recognition object images attached with label are learned, and main objects included in the recognition object image are recognized. In the case where a plurality of the main objects exist in the learned image, an area rectangle is specified, and the image corresponding to the specified area is attached with a label and the learning is performed. In addition, in the convolution neutral network, the main objects in the image and the positions of the objects can also be determined.
As the convolution neutral network is described more in detail, in the object recognition process, edge extraction process and the like is performed on the recognition object image, candidate areas are extracted based on localized features, the candidate areas are input to the convolution neutral network to extract feature vectors, classification is performed, and the candidate area having the highest degree of certainty among the classified candidate areas is acquired as a result of the recognition. The degree of certainty is a quantity representing how higher a degree of similarity between a certain image area and a subject of the image learned together with the label is than the degree of similarity of another class.

Furthermore, the calculation unit 511 may calculate the sales, the profit, and the profit rate for each position of the player on each of the gaming tables 4, and the table creation unit 512 may create the table and the graph in which the sales, the profits, and the profit rates are arranged in time series for each position of the player on each of the gaming tables 4. In addition, in a case where the game management system 100 includes a section recognizing the player, the sales according to the betting of the player and the profit obtained from the player may be calculated, and the table and the graph may be created, for each player.
The recording apparatus 52 records the sales, the profit, and the profit rate calculated by the calculation unit 511, in the form of the table and the graph created by the table creation unit 512.
Specifically, the calculation unit 511 calculates the total amount (the sales) of the betting amount for each of the plurality of gaming tables 4 and each game, obtains the degree of collection or the redemption with respect to which betting target, on the basis of the betting target, the betting amount, and the game result, and calculates the profit of the casino manager. In addition, the calculation unit 511 obtains a difference in the dealer amount before and after the table game, for each of the plurality of gaming tables 4 and each game, and thus, calculates the profit of the casino manager. The profit of the former is a so-called theoretical value, and the profit of the latter is a so-called result value, and it is necessary that the theoretical value and the result value are coincident with each other. The calculation unit 511 determines whether or not the theoretical value and the result value are coincident with each other, and in a case where the theoretical value and the result value are coincident with each other, the profit is adopted, and in a case where the theoretical value and the result value are not coincident with each other, a warning to that effect may be generated.
The calculation unit 511 further calculates the total amount (the sales) of the betting amount for each of the plurality of tables 4 and each game. In addition, the calculation unit 511 calculates the profit rate (the gross rate) (=Profit/Sales) on the basis of the sales and the profit (the gross) of a predetermined period or a predetermined number of games.
In addition, the calculation unit 511 recognizes the sales (the total betting amount) and the profit amount for each gaming table 4, and different tax rates are applied to the profit amount of the gaming table 4 for each area, and thus, it is possible to calculate the tax to be paid in the casino facilities. The calculation unit 511, for example, is capable of setting different tax rates such that 10% of the profit amount is paid in a VIP area, and 20% of the profit amount is paid in a Mass area. Further, in this case, in the casino facilities, in order to induce the casino guest to the VIP area where the tax rate of the tax to be paid is low, the casino facilities are capable of fulfilling the service of the VIP area, or of applying a special game rule.
In addition, the calculation unit 511 is capable of comparing the sales (the total betting amount), the profit amount, and the profit rate, with the sales in the past (for example, yesterday, last year, or the like).
The table creation unit 512 adds up the sales, the profit, and the profit rate calculated by the calculation unit 511, and creates various tables and graphs.
Furthermore, in the examples described above, the calculation unit 511 and the table creation unit 512 calculate the sales, the profit, and the profit rate for each gaming table 4, and create the table or the graph, but instead thereof or in addition thereto, may calculate the sales, the profit, and the profit rate for each pit in which the plurality of gaming tables 4 are collected, and may create a table or a graph.
The calculation unit 511 may calculate the sales, the profit, and the profit rate whenever the information of the dealer amount, the game result, and the betting contents is acquired for each game, or may calculate the sales, the profit, and the profit rate at a timing when the table creation unit 512 creates a table.
The table creation unit 512 may create a table for each period targeted by the table or the graph. For example, in a case where the table creation unit 512 creates a graph illustrating a transition of the sales for one day (for 24 hours) on each of the gaming tables 4, the table may be automatically created every 24 hours (as soon as the data is collected). Alternatively, the table creation unit 512 may create the table or the graph at a manually indicated timing, regardless of the period targeted by the table or the graph. Alternatively, the table creation unit 512 may automatically create the table or the graph at an interval shorter than the period targeted by the table or the graph. For example, adding-up for 24 hours in the past may be performed every 6 hours, and thus, the table or the graph may be created.
The alarming unit 513 determines that a peculiar situation occurs on the basis of the sales, the profit, and the profit rate calculated by the calculation unit 511, and the adding-up of the table creation unit 512, and generates an alarm. For example, the alarming unit 513 may compare the profit rate calculated by the calculation unit 511 or the profit rate for a predetermined period or for a predetermined number of games, added up by the table creation unit 512, with a predetermined first threshold value, and may generate an alarm when the profit rate is less than or equal to the first threshold value, or may compare the profit rate calculated by the calculation unit 511 or the profit rate for a predetermined period or for a predetermined number of games, added up by the table creation unit 512, with a predetermined second threshold value, and may generate an alarm when the profit rate is greater than or equal to the second threshold value. In addition, the alarming unit 513 may compare the profit and the sales with a predetermined threshold value, and thus, may generate an alarm.
The alarming unit 513 may perform more complicated analysis with respect to the sales or the profit, and may find a peculiar situation. For example, the alarming unit 513 may generate an alarm on the basis of the transition of the profit rate in the table or graph created by the table creation unit 512. In this case, the peculiar situation may be determined by using the machine learning model. The machine learning model may be a model of outputting a probability of being peculiar by using the transition of the profit rate obtained by the adding-up of the table creation unit 512 as input, and in a case where the probability is less than or equal to a predetermined threshold value, the alarming unit 513 may determine that it is the peculiar situation, and may generate an alarm.
The alarm may be realized by a section of attaching a mark to an element which is determined as being peculiar in the table or the graph created by the table creation unit 512, and in addition, in a case where such a peculiar situation occurs, the alarm may be realized by generating and outputting an image, a sound, a driving signal of an alarm device (a lamp, a buzzer, or the like), and the like. In the example of
As illustrated in
The reader/writer 70 includes a wireless unit 71, a seating button 72, a leaving button 73, and a position designation button 74. The wireless unit 71 writes in and reads out the information with respect to an RF tag 11MM built in the membership card 1M, in an RFID manner. The position designation button 74 includes buttons of “1”, “2”, “3”, “5”, “6”, “7”, and “8” respectively corresponding to seven positions of the gaming table 4, and a button “C” of cancelling the designation.
In a case where a player P arrives at a player position in the gaming table 4, a dealer D keeps the membership card 1M from the player P, and allows the reader/writer 70 to read out the membership card 1M. Specifically, the dealer D presses the position designation button 74 of the corresponding player position, presses the seating button 72, holds the membership card 1M in the wireless unit 71, and reads out the information recorded in the membership card 1M. Accordingly, the reader/writer 70 is capable of specifying the player P in each player position with the member ID, and the reader/writer 70 functions as a player specification section.
The reader/writer 70 outputs (transmits) information read out by the wireless unit 71, a seating signal according to the press of the seating button 72, and information of the player position where the player corresponding to the member ID is seated, to the control device 14. The control device 14 records the information received from the reader/writer 70, and records time of receiving the seating signal as a start time. The start time is recorded in the form of date and time. In addition, the control device 14 transmits the information of the start time and the member ID received from the reader/writer 70, to the management device 50.
The control device 14 recognizes in which player position the player P of which member ID plays, on the basis of the member ID received from the reader/writer 70 and the information of the player position. That is, the control device 14 is capable of associating each player position of the gaming table 4 with the player P to be specified in the gaming table 4. The control device 14 may obtain the betting amount, a paying amount, and a collection amount with respect to each of the members ID, and may record the amount, while the player P plays a game a plurality of times.
The dealer D allows the reader/writer 70 to read out the kept membership card 1M from the player P when the player P is separated from the gaming table 4. In this case, the dealer D presses the leaving button 73, holds the membership card 1M in the wireless unit 71, and reads out the member ID from the membership card 1M.
The reader/writer 70 outputs (transmits) the member ID and a leaving signal to the control device 14. In a case where the member ID and the leaving signal are received from the reader/writer 70, the control device 14 records time of receiving the leaving signal as an end time. The end time is recorded in the form of date and time. In addition, the control device 14 obtains a cumulative betting amount and a cumulative balance with respect to the member ID, from the start time to the end time. Further, the control device 14 calculates an acquisition point on the basis of the cumulative betting amount from the start time to the end time.
The control device 14 adds the calculated acquisition point to the retained point read out from the membership card 1M at the time of seating, and updates the retained point. In addition, all of the acquisition point for the last three days, the acquisition point for the last one month, and the acquisition point for the last one year are updated on the basis of the calculated acquisition point. The control device 14 outputs the updated retained point, the updated acquisition point for the last three days, the updated acquisition point for the last one month, and the updated acquisition point for the last one year, and the cumulative balance from the start time to the end time, to the reader/writer 70. The reader/writer 70 replaces the information of the membership card 1M with the information described above. Furthermore, the cumulative balance from the start time to the end time is recorded as the recent balance.
According to the function of the control device 14 and the reader/writer 70, it is possible to apply a point corresponding to the actual betting amount to the membership card 1M, and it is possible for the player P to store the retained point in the membership card 1M.
A display 15 (see
The display 15 displays various kinds of information. For example, when a game table 4 is closed, an indication (for example, the character of “CLOSED”) indicating that the game table 4 is closed is displayed, and when the game table 4 is opened, game conditions such as a minimum bet amount (for example, the character of “MIN. $100”) and a maximum bet amount (for example, the character of “MAX. $100,000”) are displayed.
Two right grooves include a collection float 171 for temporarily accommodating the chips 9 collected from a losing player P at the time of liquidation and an accommodation float 172 for accommodating the chips 9 for each value. The dealer D temporarily accommodates the chips 9 collected from the game table 4 in the collection float 171, and then withdraws the chips 9 from the accommodation float 172 to a winning player P, and finally accommodates the chips 9 accommodated in the collection float 171 in the accommodation float 172 corresponding to each value.
On the upper side of the chip tray 17, there are three confirmation lamps including a bet confirmation lamp 173, a collection confirmation lamp 174, and a withdrawal confirmation lamp 175. The bet confirmation lamp 173 is turned on according to the result of confirming whether there is no variation (late betting or unbetting) in the chips 9 betted between the game start time and the game end time. The collection confirmation lamp 174 is turned on in accordance with a confirmation result of whether or not a collection amount and the collected chips 9 are authentic. The withdrawal confirmation lamp 175 is turned on in accordance with a confirmation result as to whether a withdrawal amount is correct.
An RFID reader 176 for reading an RFID tag built in the chip 9 is provided inside the chip tray 17. RFID tags of the chips 9 accommodated in all grooves including the collection float 171 and the accommodation float 172 may be read by the RFID reader 176. Since information indicating the value of the chip 9 is recorded in the RFID tag of each chip 9 as described above, the RFID reader 176 reads the RFID tags of all the chips 9 in the chip tray 17, so that a total amount of the chips 9 in the chip tray 17 may be determined.
Moreover, the RFID reader 176 may read and sort the RFID tag of the chip 9 accommodated in the collection float 171 and the RFID tag of the chip 9 accommodated in the accommodation float 172. That is, when reading the RFID tag, the RFID 176 may distinguish whether the RFID tag is the RFID tag of the chip 9 accommodated in the collection float 171 or the RFID tag of the chip 9 accommodated in the accommodation float 172. Moreover, in order to perform such reading and sorting, the RFID reader 176 may separately include an antenna for reading the RFID tag of the chip 9 accommodated in the collection float 171 and an antenna for reading the RFID tag of the chip 9 accommodated in the accommodation float 172 or may include the antenna for each groove.
Further, the confirmation unit 179 is connected to the bet confirmation lamp 173, the collection confirmation lamp 174, and the withdrawal confirmation lamp 175 to control the lamps. Specifically, the confirmation unit 179 controls lighting on, blinking, and lighting off of the bet confirmation lamp 173, the collection confirmation lamp 174, and the withdrawal confirmation lamp 175 and controls emission colors thereof. An operation of the confirmation unit 179 will be described later.
As described above, information for detecting fraud or mistake (hereinafter, simply referred to as “fraud”) is input into the control device 14 from each of a camera 2, a card distribution device 3, and a chip tray 17. Hereinafter, a method for detecting the fraud for each game will be described.
Among the steps, the determination and confirmation of the bet information of the chip 9 (step S122), the confirmation of collection of the chip 9 and the judgment of authenticity (step S123), and the confirmation of withdrawal of the chip 9 (step S124) are executed by the bet information determination and confirmation unit 1791, the collection confirmation unit 1792, the authenticity judgment unit 1793, and the withdrawal confirmation unit 1794 of the confirmation unit 179 of the chip tray 17, respectively.
A monitor is connected to the control device 14, and a screen for confirmation is displayed on the monitor with respect to the determination and confirmation of the bet information of the chip 9 (step S122), the confirmation of the collection and the judgment of authenticity (step S123), and the confirmation of the withdrawal of the chip 9 (step S124). The monitor is connected to the control device 14, installed in a backyard, and visually checked by an observer. Moreover, the monitor may be installed in the game table 4 instead of the backyard or in addition to the backyard.
First, a bet by the player P is started by an instruction of the dealer D (step S01). The player P makes a bet by placing the chip 9 in each of the bet areas. When all of the players P finish betting, the dealer D signs “no more bet” (step S02) and thereafter, the player P is not allowed to change a bet target and a bet amount.
When the bet ends, the dealer D draws a first card from the card distribution device 3 (step S03). When the card distribution device 3 detects that the first card is drawn (step S31) when the card draw is detected for the first time after a standby button 133 of the previous game is pressed, and the time when a punching unit 40 performs punching, is recorded in a recording unit 41, and reported to the control device 14.
The control device 14 controls the camera 2 to photograph the bet area (step S21). The camera 2 transmits the photographed image to the control device 14 and the control device 14 performs image recognition on the image and recognizes bet information at the start of the game (step S501). Further, the control device 14 controls the chip tray 17 to read all the chips 9 in the chip tray 17 by the RFID reader 176 and confirms the total amount of all the chips 9 in the chip tray 17 (step S171).
Moreover, the camera 2 may continuously photograph the bet area at predetermined time intervals and transmit the image to the control device 14. In this case, the control device 14 receives a report of detection of drawing of the first card from the card distribution device 3 and thereafter, performs the image recognition on the image acquired from the camera 2 for the first time to recognize the bet information at the start of the game. Here, the bet information is information indicating which player performs betting, to which bet target (PLAYER, BANKER, TIE, PLAYER PAIR, and BANKER PAIR) betting is performed, which value of chip 9 is bet, and how many chips are bet. The control device 14 stores the bet information at the start of the game.
The dealer D draws out the cards in order and draws the last card (step S04), and when all of the cards through a squeeze by the player P is opened (step S05), the game result is determined on the game table 4. Moreover, as described above, when the dealer D draws out the cards in order, the card distribution device 3 reads a rank and a suit of the card to be drawn.
When all of the cards are opened, the dealer D presses the standby button 133 of the card distribution device 3 (step S06). When the card distribution device 3 detects the pressing of the standby button 133 (step S32), the game result is judged based on the ranks and the suits of the cards read up to that time and a rule of a baccarat (step S33), and a display lamp 13 is turned on according to the game result (step S34).
The dealer D compares the game result judged from the opened card on the game table 4 with the game result indicated by the display lamp 13 of the card distribution device 3 and confirms that both game results match each other (step S07). The confirmation corresponds to determination and confirmation (step S121) of the game result of the flow of
Meanwhile, when the card distribution device 3 detects pressing of the standby button 133 (step S32), the card distribution device 3 reports the detected pressing to the control device 14. The control device 14 controls the camera 2 to photograph a bet area 44 (step S22). The camera 2 transmits the photographed image to the control device 14 and the control device 14 performs image recognition on the image and recognizes the bet information at the end of the game (step S502).
Since the player P is not permitted to change bet contents (bet target and bet amount) from the start of the game (end of the bet) to the end of the game, when there is no fraud, the bet information (step S501) at the start of the game and the bet information (step S502) at the end of the game recognized by the control device 5 may match each other. Herein, the control device 14 compares both bet information (step S503).
The control device 14 reports a match or a mismatch to the chip tray 17 as a comparison result. A case where the comparison result is the mismatch includes a case where the total number or the total amount of chips 9 at the end of the game is larger than that at the start of the game (late betting tried by the winning player P) and a case where the total number or the total amount of chips 9 at the end of the game is smaller than that at the start of the game (unbetting tried by the losing player P).
The bet information determination and confirmation unit 1791 of the chip tray 17 turns on the bet confirmation lamp 173 according to the comparison result from the control device 14 (step S172). Herein, the bet information determination and confirmation unit 1791 turns on the bet confirmation lamp 173 in green when the comparison result is the match and turns on the bet confirmation lamp 173 in yellow when the comparison result is not mismatch.
The dealer D confirms that the bet confirmation lamp 173 is turned on in green (step S08) and collects the chips 9 from the losing player P and stores the collected chips 9 in the collection float 171 (step S09). The control device 14 calculates the amount (collection amount) of the chip 9 to be collected based on the recognized bet information and the game result judged by the card distribution device 3 (step S504). The collection amount is calculated from the values and the number of the chips 9 to be collected. The control device 14 notifies the calculated collection amount to the chip tray 17.
When the chip 9 collected by the dealer D is put in the collection float 171 of the chip tray 17, the collection confirmation unit 1792 of the chip tray 17 acquires the read information from the RFID reader 176, determines the collection amount of the chips 9 accommodated in the collection float 171, and compares the determined collection amount with the calculated collection amount notified from the control device 14 to confirm whether the collection amount (the number of chips for each value) is correct (step S173). Moreover, since the RFID reader 176 may obtain information on the number of chips for each value as the read information as a result of reading the chip 9, the control device 14 also calculates the collection amount as the number of chips for each value. Therefore, even in the comparison, it is judged whether the number of chips for each value matches.
Further, in this case, the authenticity judgment unit 1793 performs the authenticity judgment of the collected chips 9 by judging whether the number of chips 9 recognized by the RFID reader 176 and the number of chips 9 detected by the optical sensor 178 match each other (step S174). In the case where an illegal chip 9 not containing the RFID tag is collected from the player P, the illegal chip 9 is detected by the optical sensor 178, but the illegal chip 9 is not detected by the RFID reader 176, and as a result, there is the mismatch between the both sides, thereby detecting the existence of the illegal chip 9.
The collection confirmation unit 1792 and the authenticity judgment unit 1793 turn on the collection confirmation lamp 174 according to the results of the confirmation of the collection amount and the authenticity judgment (step S175). Specifically, the chip tray 17 turns on the collection confirmation lamp 174 in green when the collection amount detected by the RFID reader 176 matches the calculated collection amount acquired from the control device 14 and the collected chip 9 is authentic and makes the collection confirmation lamp 174 blink in yellow when both the collection amounts do not match each other or the illegal chip 9 exists.
The dealer D confirms that the collection confirmation lamp 174 is turned on in green (step S10) and withdraws the chip 9 to the winning player (step S12). The control device 14 calculates the withdrawal amount of the chip 9 based on the recognized bet information and the game result judged by the card distribution device 3 (step S505). The control device 14 notifies the chip tray 17 of the calculated withdrawal amount. Herein, the withdrawal amount is also calculated as information on the number of chips for each value.
When the dealer D withdraws the chip 9 from the chip tray 17 onto the game table 4, the chip tray 17 calculates the withdrawal amount of the chip 9 accommodated in the chip tray 17 by using the RFID reader 176 and compares the calculated withdrawal amount with the calculated withdrawal amount notified from the control device 14 to confirm whether the withdrawal amount is correct (step S176). The withdrawal amount may be obtained as the information on the number of chips for each value by the RFID reader 176.
Herein, the confirmation of the withdrawal amount in the chip tray 17 will be described. The chip tray 17 confirms the total amount of the chip tray 17 when the game starts (step S171). In addition, notification of the calculated collection amount and withdrawal amount is received from the control device 14 (steps S504 and S505). An increase/decrease amount is calculated from the collection amount and the withdrawal amount. By adding the calculated increase/decrease amount to the total amount of the chips 9 in the chip tray 17 at the start of the game confirmed in step S171, the total amount of the chips 9 to be in the chip tray 17 after the liquidation is calculated. Herein, the total amount of the chips 9 is also calculated as the number of chips for each value.
When the calculated total amount matches the total amount of the chips 9 read by the RFID reader 176 after withdrawal, it is regarded that the collection and the withdrawal are performed accurately. Since it is confirmed that collection is performed correctly in step S173, this means that the withdrawal is correctly performed. Accordingly, the withdrawal confirmation unit 1794 of the chip tray 17 judges whether the withdrawal amount is correct by comparing the total amount (the number of chips for each value) (acquired from the control device 14) of the chips 9 to be in the chip tray 17 after the liquidation which may be obtained by the calculation and the total amount (the number of chips for each value) of the chips 9 read by the RFID reader 176 (step S176).
Moreover, in place of the above, the confirmation of the withdrawal may be made by the following method. That is, after confirming that the collection is correctly performed, the RFID reader 176 of the chip tray 17 reads the RFID tags of all of the chips 9 in the chip tray 17 and determines an actual total amount (the number of chips for each value) before withdrawal after collection in the chip tray 17, and the RFID reader 176 reads the RFID tags of all of the chips 9 in the chip tray 17 again after the withdrawal and determines the actual total amount in the chip tray 17 (the number of chips for each value) after the withdrawal and as a result, calculates an amount actually withdrawn from the chip tray 17 and compares the actual withdrawal amount and the withdrawal amount calculated by the control device 14, thereby confirming whether the withdrawal is correctly performed.
The chip tray 17 turns on the withdrawal confirmation lamp 175 according to the confirmation result of the withdrawal amount (step S177). Specifically, the chip tray 17 turns on the withdrawal confirmation lamp 175 in green when the actual withdrawal amount matches the calculated withdrawal amount and makes the withdrawal confirmation lamp 175 blink in yellow when the actual withdrawal amount does not match the calculated withdrawal amount. The dealer confirms that the withdrawal confirmation lamp 175 is turned on in green (step S12) and ends the game.
Moreover, in the embodiment, an example in which the confirmation unit 179 is provided in the chip tray 17 is described, but some or all functions of the confirmation unit 179 may be provided in the control device 14. In this case, after the control device 14 performs processing by the confirmation unit 179, the control device 14 instructs the bet confirmation lamp 173, the collection confirmation lamp 174, and the withdrawal confirmation lamp 175 of the chip tray 17 to be turned on, blink, and be turned off.
“(1) 1st Card” at the lower end indicates the number of chips 9 accommodated in the chip tray 17 for each value of the chip 9 at the start of the game (when the first card is drawn). “(2) Game Result” indicates a balance according to the result of the game by the number of chips 9 for each value. In this example, it is shown that four 10,000-dollar chips decrease and three 1,000-dollar chips increase in the chip tray 17 by liquidating the game.
“(3) Calculated” indicates the result of calculating the balance of (2) for (1), that is, the number of chips 9 for each value to be in the chip tray 17 after liquidation. “(4) Discard” indicates the actual number of chips 9 in the chip tray 17 read by the RFID reader 176 by triggering discarding of cards in a discard box. “(5) Judgment” outputs the comparison result between (3) and (4). That is, (5) Judgment indicates the comparison result between the number of chips 9 calculated in (3) and the actual number of chips 9 read by the RFID reader 176 in (4).
Moreover, even though the monitor screens as shown in
As described above, in a game table system of the embodiment, the fraud in each stage of the game is detected by using various sensing techniques and image recognition techniques. A management system including the game table system and a plurality of game table systems of the embodiment uses the results of the sensing and image recognition not only as fraud discovery for each game but also as management information of a casino. Moreover, the casino business information also includes advanced fraud detection that may not be discovered only by fraud detection for each game. To this end, the control device 14 of each game table system is connected to a management device 60 to transmit various information to the management device 60.
There are two kinds of table surface layouts (hereinafter, simply referred to as “layout”) in four game tables. In a game table 4A of a first type layout (Type-a), positions (player positions 1, 2, 3, 5, 6, 7, and 8) for seven players are prepared and in a game table 4B of a second type layout (Type-b), positions (player positions 1, 2, 3, 5, and 6) for five players are prepared.
In the game table 4A of the first type, bet areas of PLAYER, BANKER, TIE, PLAYER PAIR, and BANKER PAIR as the bet targets are provided at positions corresponding to the respective player positions. Meanwhile, in the game table 4B of the second type, only the bet areas of PLAYER and BANKER as the bet targets are provided at the positions corresponding to the respective player positions and the bet areas of TIE, PLAYER PAIR, and BANKER PAIR are respectively decided and arranged.
The “date and time” is the start date and time of the game. Moreover, as the “date and time”, in addition to or in place of the game start date and time, the end date and time of the game may be recorded. The “table ID” is an ID uniquely given to each table. The table may be identified by the table ID. The “layout” represents a layout type of a table surface. In the example of
The “minimum bet amount” is a minimum bet amount set in the game. Players who participate in the game need to bet chips whose amount is equal to or more than the minimum bet amount in each game. Moreover, the minimum bet amount may be appropriately changed at the timing between the game and the game. Further, in addition to the minimum bet amount, a maximum bet amount which is a maximum bet amount may be set and recorded in one game of the game table 4.
The “dealer ID” is an ID for identifying the dealer D in charge of dealing in the game table 4. Each dealer D is provided with a dealer card incorporating an IC tag storing a dealer ID so that when the dealer D arrives at the game table 4, a reader/writer 5 reads the IC tag of the dealer card and outputs a dealer ID read by the reader/writer 5 to the control device 14. Alternatively, the control device 14 may have an input device and the dealer D arriving at the game table 4 may input the dealer ID thereof from the input device.
The “bet time” is a time from the start of betting up to the end of the betting. When the control device 14 determines that withdrawal of the previous game is normally completed in the chip tray 17, the control device 14 recognizes that the betting starts. Further, the control device 14 recognizes that the betting ends when the card distribution device 3 detects the drawing of the first card. When the first card is drawn, the card distribution device 3 punches the time and reports the time to the control device 14, so that the control device 14 determines the bet end time based on the report.
Moreover, the discard box for discarding the used card may be provided in the game table 4 and a sensor may be provided in the discard box and in this case, when the control device 14 detects the discard of the card by the sensor, the control device 14 may recognize that the betting of the next game starts. Further, an operation member may be provided to instruct the card distribution device 3 or the like to start a predetermined bet and the dealer may operate the operation member immediately before the start of betting and in that case, the control device 14 may recognize that the betting starts when detecting the operation of the operation member. In addition, the control device 14 may recognize the start of the betting by detecting the bet chip 9 by recognizing the image of the camera 2.
The “gaming time” is the time until the dealer D draws the first card from the card distribution device 3 and then the standby button 133 is pressed. That is, the game time includes the time until the last card is withdrawn from the card distribution device 3, all cards are opened through squeezing by the player P, the game result is made clear on the game table 4, and then the dealer D presses the standby button 133 according to the game result.
The “chip collection time” is a time until the game ends and then the collection of the chip 9 from the losing player P is completed. As described above, a time at which the dealer D presses the standby button 133 immediately after the result of the game is confirmed is set as the end time of the game. Further, the control device 14 sets a time at which collection confirmation is reported from the chip tray 17 as the collection end time.
The “chip withdrawal time” is a time from completion of the collection of the chip 9 from the losing player P until the withdrawal of the chip 9 to the winning player P is completed. The control device 14 sets a time at which withdrawal confirmation is reported from the chip tray 17 as the withdrawal end time. Alternatively, the control device 14 may determine the chip collection time and the chip withdrawal time by analyzing the image of the camera 2. Alternatively, the time when the discard of the card in the discard box is detected may be the end of “chip withdrawal time”.
The “game result” is PLAYER, BANKER, or TIE and the presence or absence of PLAYER PAIR and BANKER PAIR. As described above, by determining the game result by reading the rank and the suit of the card withdrawn from the card distribution device 3, the control device 14 receives the information on the game result from the card distribution device 3.
The “dealer chip amount at the start” is the total amount of chips 9 accommodated in the dealer tray 17 at the start of the game, and is acquired at the chip tray 17 in step S171 of
The “verification result” is a result of verifying whether a theoretical dealer chip amount after liquidation and an actual dealer chip amount after liquidation match each other and is indicated by either OK or NG. A table management control device 50 calculates a theoretical balance based on the actual total amount after liquidation (“post-liquidation dealer chip amount” described above) of the chips 9 of the chip tray 17 read by the chip tray 17 and the game result determined by the reading of the card by the card distribution device 3 and adds the balance to the actual total amount (“start dealer chip amount” described above) of the chips 9 in the chip tray 17 at the start, which is read by the chip tray 17 and calculates the theoretical total amount (theoretical post-liquidation dealer chip amount) of the chip tray 17 after liquidation to compare the actual total amount and the theoretical total amount (corresponding to step S176 in
The control device 14 compares the theoretical post-liquidation dealer chip amount with the actual post-liquidation dealer chip amount for each game, and sets the verification result to “OK” in the case of the match and to “NG” in the case of the mismatch.
Moreover, the game record includes, for each “player position”, “member ID”, “bet amount”, “bet target”, “withdrawal (−)/collection (+)”, “sales”, and “net profit”. As “player position”, as shown in
“Bet amount” is a bet amount for each player position and is indicated by the number of chips for each value of the chip 9 at each player position. In addition thereto or in place thereof, information on the bet amount may be displayed for each stack of the chips 9 when image recognition is performed by the camera 2 and the measurement device 21 as the information of “bet amount”. In this case, “bet amount” includes information on the number of stacks and the value and the number of chips 9 for each stack for each player position.
The “withdrawal (−)/collection (+)” is the amount of withdrawal or collection for each player position. The control device 14 records an amount paid out from the dealer D separately from the bet amount by writing a minus sign for the winning player P and records a plus sign to the bet amount for the losing player P, as the “withdrawal (−)/collection (+)”.
The “sales” is a total bet amount acquired by adding the bet amounts of all players P in the game. The control device 14 calculates and records “sales” by adding the bet amounts of all of the players P. The “net profit” is an amount acquired by adding the withdrawal amounts (−) and the collection amounts (+) of all of the players in the game and is a profit of a game organizer (house) in the game. The control device 14 calculates and records the “net profit” by adding the withdrawal amounts and the collection amounts of all of the players P. Moreover, the sales (total bet amount) are recorded as the number of chips 9 for each value.
As described above, the control device 14 outputs a net profit Y which is a winning or losing amount of the game organizer and a total bet amount (sales) B which is a total amount of chips 9 placed by the player P for each game table 4. In particular, the camera 2 and the measurement device 21 detect the total bet amount B for each player position on the game table 4 and the control device 14 outputs information of the total bet amount B for each player P as the game record and for each player position.
The control device 14 generates the game record for each game. The control device 14 of each game table 4 is connected to the management device 60 and the game record generated by the control device 14 is transmitted from the control device 14 to the management device 60. Moreover, the management device 60 is connected to the control device 14 to be communicable by a wired or wireless way. The management device 60 counts the game records obtained from the plurality of control devices 14 and performs the following processing.
The management device 60 is a computer having a processor and a memory, and the arithmetic device 61, which operates in accordance with a management control program of the embodiment, includes the sales balance management unit 611, the loss management unit 612, the operation management unit 613, the layout management unit 614, the point management unit 615, the minimum bet management unit 616, and the dealer chip management unit 617. The management device 60 also further includes a recording device such as a hard disk. Further, the management device 60 has a communication function for communication with the control device 14.
The sales balance management unit 611 manages the sales of the house in a predetermined period by the value and the number of chips 9 betted for each game table 4 and also manages the total sales amount of each game table 4. In addition, the sales balance management unit 611 also manages the sales of the house in a predetermined period by the number of chips 9 for each value. Moreover, the sales balance management unit 611 also manages the sales of the house in a predetermined period even by the total sales amount of the sum of all game tables 4. Figures managed by the sales balance management unit 611 are shown in the sales table.
The sales balance management unit 611 manages an income (gross profit) of the house in a predetermined period for each game table 4. Further, the sales balance management unit 611 manages a total gross profit of all game tables 4 in a predetermined period. Further, the sales balance management unit 611 also manages a gross profit rate for each game table 4 in a predetermined period and a total gross profit rate of all of the game tables 4. In the gross profit table, the numerical values managed by the sales balance management unit 611 are shown together with the sales of each game table 4 and the total sales of all of the game tables 4.
As described above, the management device 60 manages the sales and the gross profit rate. The income of the house may be obtained as an amount acquired by subtracting loss due to fraud or mistake from the product of the sales and the gross profit rate. That is, Equation (1) below is established:
Income=Sales×Gross profit rate−Loss (1)
Herein, the game organizer may increase the income (gross profit) by increasing the sales, increasing the gross profit rate, and reducing the loss. Moreover, reducing the loss due to the mistake or fraud is implemented by a table system using the various sensors. Hereinafter, processing for increasing the sales and the gross profit rate will be described.
With information on the sales and the gross profit rate alone, it is difficult to link the information to a concrete management measure for increasing the sales and the gross profit rate. Herein, the management device 60 decomposes the sales and the gross profit rate into a plurality of constituent elements and calculates information useful for improving each element.
The sales is represented by the product of the number of transactions and the unit price (hereinafter, referred to as “bet unit price”) of the bet amount. That is, Equation (2) below is established:
Sales=Number of transactions×Bet unit price (2)
Herein, the number of transactions means a play of one game by one player P. For example, when three players P are playing on one game table 4, the number of transactions in one game is three and when two players P are playing on each of three game tables 4, the number of transactions in one game is 2×3=6. Further, the bet unit price means an average bet amount (sales) (in one transaction) in one game of each player P. That is, in order to increase the sales, it is preferable to increase the number of transactions and increase the bet unit price.
The number of transactions is represented by the product of the number of players (number of guests) and a turnover rate. That is, Equation (3) below is established:
Number of transactions=Number of players×Rotation rate (3)
Herein, the number of players means the number of players who participate in the game (takes a bet) and the turnover rate means a reciprocal number of a time required for one game (i.e., game progress speed). Therefore, in order to increase the number of transactions, it is preferable to increase the number of players who participate in the game and the turnover rate of the game.
Further, the gross profit rate is a deduction rate (house edge) when the game result matches a theoretical probability. Therefore, the gross profit rate is represented by the product of a winning rate and the deduction rate and Equation (4) below is established:
Gross profit rate=Winning rate×Deduction rate (4)
Herein, the winning rate is a rate indicating how far a house side overcomes from a theoretical house winning rate derived from a rule of the game, and becomes 1 when a winning rate of the house matches a theoretical winning rate, larger than 1 when the winning rate of the house is higher than the theoretical winning rate, and smaller than 1 when the winning rate of the house is lower than the theoretical winning rate. Further, the winning rate becomes 1 when the winning rate of the player P matches the theoretical winning rate derived from the rule of the game, smaller than 1 when the winning rate of the player P is higher than the theoretical winning rate, and larger than 1 when the winning rate of the player P is lower than the theoretical winning rate.
Further, the reduction rate is a rate of a fee collected by the house side to the bet amount and is determined by the rule of the game including setting of odds. The deduction rate is set so that the house side may receive a benefit of, for example, 1 to 3% when the winning rate is 1, that is, the result of the game matches the theoretical result. For example, in a game that predicts a pip of a dice, the winning rate of the player is ⅙, but by setting the odds to 5.9 times instead of 6 times, the deduction rate of approximately 1.7% is set.
As the deduction rate, different values may be set for each type of layout of the game table 4 or for each bet area. For example, deduction rates are set in TIE and PAIR of the baccarat, which are different from those of BANKER and PLAYER, and as a result, different deduction rates from other red or black numbers are set even in “0” and “00” of a roulette.
From Equations (1) to (4) above, the income (gross profit) of the house may be decomposed into a plurality of elements as in Equation (5) below.
Income=Number of players×Turnover rate×Bet unit price×Winning rate×Deduction rate−Loss (5)
First, by element decomposition of Equation (1), a large structure of the income may be analyzed. For example, when the income (gross profit) is 10,000 dollars, 10,000 dollars may be determined as 1% of profit on 1 million dollar sales, 10% of profit of 100,000 dollars, 0.1% of profit of 10 million dollars, or the like. Herein, the sales balance management unit 611 compares the gross profit rate with a predetermined reference gross profit rate (e.g., 2%) or a reference gross profit rate range (e.g., 1 to 3%) and when the gross profit rate is extremely low (for example, 1% or less) and when the gross profit rate is extremely high (for example, 3% or more), the sales balance management unit 611 generates a warning.
As shown in Equation (4), the gross profit rate may be decomposed into the winning rate and the deduction rate, but since the deduction rate is set by the game organizer, when the gross profit rate is extremely high or low, it is considered that the winning rate is extremely high or low. Herein, when the gross profit rate is extremely high or low, fraud such as manipulating the winning rate by the player P or dealer D is suspected.
Herein, the sales balance management unit 611 calculates the gross profit rates in a predetermined period for each player P, for each dealer D, and for each game table 4, respectively. Even in respect to the gross profit rate, the sales balance management unit 611 generates the warning when the gross profit rate is extremely low and when the gross profit rate is extremely high. The generated warning may be notified to a communication account (for example, an e-mail address) of the game organizer or may be recorded in the recording unit 62.
The sales balance management unit 611 generates statistics of each of the number of games, the number of players, and the bet unit price in a predetermined period by analyzing the game record obtained from each control device 14. When the sales is not ideal, the game organizer may know whether there is room for improvement in the number of games, the number of players, or the bet unit price and may also verify whether an effect of such improvement measures may be obtained by looking at trends of the number of games, the number of players, and the bet unit price when taking the improvement measures for increasing the number of games, the number of players, and the bet unit price.
The sales balance management unit 611 calculates and outputs a sales-versus-profit rate X which is a ratio between a net profit Y which is the winning or losing amount of the game organizer and a total bet amount (sales) B which is the total amount of chips 9 placed by the player P. Further, the sales balance management unit 611 compares the sales-versus-profit rate X with a theoretical profit rate or a past average profit rate and outputs the comparison result. The sales balance management unit 611 calculates the sales-versus-profit rate X for each game table 4, each player P, each player position, or each dealer D for every predetermined period or for each game and outputs the calculated sales-versus-profit rate X if necessary.
Further, the sales balance management unit 611 determines a relationship between the number of games and the time (betting time+gaming time+chip collection time+chip withdrawal time) required for the number of games. In addition, the sales balance management unit 611 calculates, for each player P or each game table 4, and/or for each dealer D in charge of each game table 4, the total bet amount B around a predetermined number of games, the winning or losing amount Y of the game organizer, and/or the sales-versus-profit rate X, and outputs the calculated total bet amount B around the predetermined number of games, winning or losing amount Y of the game organizer, and/or sales-versus-profit rate as necessary.
In addition, the sales balance management device 611 records 1) a bet amount B of individual games to be played on the game table 4, 2) a winning or losing result (W&L) of the individual games performed on the game table 4, and 3) a gross profit rate R % based on the rule of the game to be performed, in the recording device 62. Then, the sales balance management device 611 outputs the total profit Y by calculating Equation (6) below by using the information of 1) to 3) for each game and/or information of 1) to 3) at a predetermined time or period.
Y=Σ(B×W&L×R %) (6)
Here, 1) the bet amount B of the individual game performed on the game table 4 is the sales in each game. 2) The winning and losing result (W & L) of individual games played on the game table 4 is synonymous with the above-mentioned winning rate. For the winning/losing result (W & L), the winning/losing result is +1 when the casino side wins (collects the chip), but −1 when the casino side loses (withdraws the chip). 3) The gross profit rate (R %) based on the rule of the game played on the game table is synonymous with the above deduction rate and is determined by the rule of the game including the setting of the odds. For example, the gross profit rate becomes 100% when betting on BANKER or PLAYER (that is, when the player wins, he/she receives withdrawal equal to the bet amount and when the player loses, the bet amount is fully collected), 800% in the case where the player wins when betting on PAIR, and 100% in the case where the dealer wins (that is, when the player wins, the player is withdrawn 8 times larger than the bet amount and when the player loses, the bet amount is fully collected).
In the case where different gross profit rates are set for each type of layout of the game table 4 or for each bet area (bet target) (for example, when the odds of TIE and PAIR increase), the sales balance management unit 611 calculates the gross profit Y by adopting the different gross profit rates (R1%, R2%, . . . ). When different gross profit rates are set for each type of layout of the game table 4 or for each bet area (bet target), the sales balance management unit 611 outputs distribution states of the total bet amount TB of the game and/or the bet amount B of the game for each of types of layouts of the different gross profit rates (R1%, R2%, . . . ) or for each bet area (bet target). Thus, for example, it is possible to determine only the bet amount to TIE.
Moreover, when different gross profit rates are set for each type of layout of the game table 4 or for each bet area (bet target), the sales balance management unit 611 outputs the distribution state of the total bet amount TB of the game and/or the bet amount B of the game for each of different gross profit rates (R1%, R2%, . . . ), for each type of layout, or for each bet area (bet target). Thus, for example, it is possible to determine the bet amount of the bet target whose gross profit rate is extremely high.
Moreover, when different gross profit rates are set for each type of layout of the game table 4 or for each bet area, the sales balance management unit 611 compares the gross profits Y or the total gross profit rates (R %) of respective game tables 4 in units of the game tables 4 having the types of layouts or bet areas (bet target) of the different gross profit rates (R1%, R2%, . . . ). As a result, the gross profit rates of the tables may be compared with each other.
The loss management unit 612 detects the fraud or the mistake by statistically analyzing records of a plurality of games in a plurality of game tables 4, rather than detecting the fraud or mistake for each game. The loss management unit 612 counts and outputs the number of times of mismatch detection of comparing whether the increase/decrease amount of the total amount of the chips 9 existing in the chip tray 17 matches the winning or losing amount Y of the game organizer side. The mismatch may be detected as the case where the “verification result” of the game record (see
Further, the loss management unit 612 compares the increase/decrease amount of the total amount of the chips 9 existing in the chip tray 17 and the winning or losing amount Y of the game organizer side and counts and outputs a mismatch amount L when both amounts mismatch each other. The loss management unit 612 may calculate the mismatch amount L by comparing a difference between the “start dealer chip amount” and the “post-liquidation dealer chip amount” of the game record and the “net profit”. The loss management unit 61 records the count values for each game table 4, for each dealer D in charge of each game table 4, and for each player P in the recording device 62. The loss management unit 612 periodically refers to the recording device 62 to determine and outputs a cumulative amount of the mismatch amount L. As a result, when there is a game table 4, a dealer D, or a player P having a high count value, it is possible to discover the fraud by further executing a new investigation.
Further, the loss management unit 612 compares the increase/decrease amount of the total amount of the chips 9 existing in the chip tray 17 and the winning or losing amount Y of the game organizer side, and counts the mismatch amount (loss amount) L, corrects Equation (6) to Equation (7) below, and outputs a gross profit Y′.
Y′=Σ(B×W&L×R %±L) (7)
As a result, it is possible to calculate the gross profit in consideration of the loss amount L.
Furthermore, at the time when a predetermined number of games end, the loss management unit 612 compares a result of a total amount of the actual winning rate and the gross profit Y and a number based on probability statistical calculation or a number based on past accumulated data for each player P, for each dealer D in charge of each game table 4, and for each game table 4 and judges whether there is a significant difference between them to specify a player P, a dealer D, and a game table 4 in which there is the significant difference. As a result, since it is possible to discover a player P or a dealer D who is extremely more likely to win or lose by comparing the number on the probability statistical calculation or the number based on the past accumulated data, it is also possible to discover the fraud which is not discovered in the game table 4.
When detecting the significant difference, the loss management unit 612 records the bet chip amount of each game table 4 in the bet area (bet position) with a different gross rate (R %) in the recording device 62 to specify whether a cause of the significant difference in a series of games in which there is the significant difference is related to the bet area (bet position) (for example, “TIE” of the baccarat) of the different gross rate (R %). As a result, for example, although the number of times of winning is standard, in the case of winning, it is possible to identify the player P who is continuously betting on a betting target of high magnification, thereby discovering the fraud.
In addition, the loss management unit 612 may determine purchase information of the chip 9 of each player P for each type of chip 9. For example, the purchase information may be acquired from a device provided in a cashier for purchasing the chip 9 and when purchasing the chip 9 with the game table 4, the purchase information may be acquired by the image recognition by the camera 2 and the measurement device 21. The purchase information includes the number of chips for each value of the purchased chip 9 and purchase date and time.
The loss management unit 612 determines the purchase information of the chip 9 of the player P in a predetermined time or period and associates the purchase information with the bet amount, the winning amount or the losing amount for each player P and records the purchase information in the recording device 62, and outputs the purchase information as necessary. As a result, it is possible to detect suspicion of money laundering due to collusion between the player P and the dealer D.
The operation management unit 613 calculates the number of games and the number of players in a predetermined period for each dealer D. Generally, as the number of players increases, it takes time to collect and withdraw the chips 9, and as a result, the turnover rate (that is, the number of games per unit time) does not become large. When the turnover rate is large despite the large number of players, it means that a progress operation of the game of the dealer D is smooth. On the contrary, when the turnover rate is small despite the small number of players, it means that there is a problem that the progress operation of the game of the dealer D is slow.
Therefore, the operation management unit 613 extracts a dealer D whose turnover rate×the number of players in a predetermined period, that is, the number of transactions is less than a predetermined threshold value. The game organizer may enhance the sales by making efforts to improve the operation so that the progress of the game is advanced with respect to the extracted dealer D.
The operation management unit 613 further creates statistics of the bet time, the gaming time, the chip collection time, and the chip withdrawal time for each dealer D. For each dealer D, it is desirable that the turnover rate is high, but it is effective to analyze how long the bet time, the chip collection time, the chip withdrawal time, and the gaming time are as a factor that does not increase the turnover rate. The length of the bet time depends largely on a betting operation of the player P and the dealer D has few elements capable of controlling the length of the bet time. Meanwhile, the length of the chip liquidation time depends largely on the operation of the dealer and may be shortened by the effort of the dealer D. Behaviors of both player P and the dealer D may influence the length of the gaming time (for example, a squeeze of the player P in the baccarat affects the gaming time).
Herein, the operation management unit 613 calculates the chip collection time/the number of players and the chip withdrawal time/the number of players for each game record. In addition, the operation management unit 613 calculates an average of the bet times for a plurality of game records, an average of the chip collection time/the number of players, an average of the chip withdrawal time/the number of players, and an average of the gaming times for each dealer D to extract a dealer D in which such an average is larger than a predetermined threshold value and a dealer D in which such an average is smaller than the predetermined threshold value. The game organizer may provide necessary guidance to the dealer D using the statistical data.
Further, the operation management unit 613 determines the dealer in charge of each game table 4 based on the game record sent from the control device 14 and detects, for each dealer, at least one element time of 1) the bet time, 2) the chip collection time, 3) the chip withdrawal time, and 4) the gaming time, and stores the detected element time in the recording device 62.
Further, the operation management unit 613 determines the bet position (bet target) and/or the number of stacks of the chip 9 placed by a game participant on the game table 4 or the number of chips 9 per stack, and outputs the bet position and/or the number of stacks or the number of chips 9 in association with the number of games and a time taken for the number of games. In addition, the operation management unit 613 determines the number of players on the game table 4 and outputs the number of players in association with the number of games and the time taken for the number of games. Herein, the time taken for the game may be the sum of the bet time, the gaming time, the chip collection time, and the chip withdrawal time of the number of games, or the sum (chip liquidation time) of only the chip collection time and the chip withdrawal time of each game (Chip settling time) or may be either the chip collection time or the chip withdrawal time.
The layout management unit 614 calculates the gross profit rate in a predetermined period for each type of layout. By studying the gross profit rate, it is possible to know which layout may make the gross profit rate higher. The layout management unit 614 calculates the bet amount for each bet target. By analyzing the bet amount of each bet target for each layout, it may be determined which layout is more desirable.
The layout management unit 614 analyzes whether the difference in layout affects the sales. Specifically, the layout management unit 614 calculates the bet unit price/minimum bet amount for each game record and performs totaling for each layout. Further, more specifically, the layout management unit 614 evaluates the layout by analyzing in which bet target (PLAYER, BANKER, TIE, PLAYER PAIR, and BANKER PAIR) the number of times of betting or the bet amount is larger for each layout. For example, it may be evaluated that the layout with a large bet amount to TIE, PLAYER PAIR, and BANKER PAIR contributes to an increase in sales.
As described above, the larger the number of players and the bet unit price, the higher the sales of the house. The number of players and the bet unit price may not be increased directly by instructing the dealer, so it is effective by the motion of the player. As the motion of the player, there are point granting and setting of the minimum bet amount. Hereinafter, the point granting and the setting of the minimum bet amount will be described in order.
The point management unit 615 grants the point to the player P who is a member and gives a benefit corresponding to the point. The player P may change the point to various benefits according to the size of the point. The point management unit 615 devises the setting of the benefit to increase the number of players and the bet unit price.
The recording unit 62 stores points owned by each member. In order to grant the points to the member, the point management unit 615 notifies the control device 14 of the granted points and updates the points owned by the corresponding member, which are stored in the recording unit 62. The control device 14 adds the points granted by the management device 60 to the points owned by the player P and updates the owned points. The reader/writer 5 records the updated owned points in the membership card 1 of the player P.
The point management unit 615 grants points of the number of points corresponding to the bet amount of the player P. Alternatively, the point managing unit 615 may determine the number of participating games for each player P in a predetermined time or period and grant the point or a status to the player P under predetermined conditions. When a value obtained by subtracting the loss amount from the gross profit of the game organizer is positive, the game organizer gains a profit and when the value is minus, the game organizer suffers a loss. The value obtained by subtracting the loss amount from the gross profit of the game organizer is called the net profit of the game organizer and cost of the game organizer related to the benefit granted to the member may be determined according to the net profit as a whole.
The point management unit 615 adjusts the ratio of the granted points to the bet amount of the player P and the relationship between the benefit and the consumption point according to the net profit. In addition, the point management unit 62 adjusts the ratio of the granted points to the bet amount of the player as a temporary campaign promotion and the relationship between the benefit and the consumption point so as to increase the number of players and the bet unit price according to the number of players and the bet unit price in the game record. The ratio of the granted points to the bet amount of the player and the relationship between the benefit and the consumption point are stored in the recording unit 62.
In addition, the point management unit 615 records in the recording device 62 at least one information of 1) the number of times of visitation to the game arcade, 2) the number of times of betting, 3) the winning amount, and 4) the losing amount for each specific game participant weekly or monthly, or in a predetermined period and reads at least one information of 1) to 4) from the recording device 62 and outputs the read information when the player P enters the casino game arcade. The fact that a specific player P visits the game arcade may be determined by confirming the ID using the membership card 1 when entering the game arcade, determined by confirming the ID using the membership card 1 when purchasing the chip, or determined by reading the membership card 1 with the reader/writer 5 on the game table 4.
The member may receive the benefit or status by consuming the owned points, but a specific grant condition is set with respect to a predetermined benefit and status in addition to the consumption of the owned point to grant the relevant benefit or status only to a player P which satisfies the grant condition.
Further, the point management unit 615 not only may grant the point and status according to the sales but also may specially give the point or status when the specific grant condition is satisfied. The specific grant condition may mean that the bet amount, the number of times of betting, the winning amount, and the losing amount satisfy the predetermined condition in a predetermined time or period. Here, the predetermined time or period may be a unit of day, a plurality of consecutive days or a unit of month, or cumulative (indefinite). Further, the point management unit 615 may additionally grant the point or status to a member to which the point is intensively granted in a predetermined time or period.
For example, since members whose net profit in a predetermined period is equal to or greater than a predetermined amount stay in the casino game arcade and participate in the game after the next day, it is effective to grant the benefit immediately available as payment of usage fee of a service (for example, postponing a check-out date of a hotel, upgrading a room, etc.) of the hotel for urging a long stay. Therefore, for example, the point management unit 615 assigns a grant condition that the net profit of the player in the predetermined period is equal to or more than a predetermined amount to the benefits such as postponing the check-out date of the hotel currently staying and upgrading the room.
Meanwhile, when the net profit of the player in the predetermined period is equal to or less than the predetermined amount, it is effective to grant a time limit chip that may be used after a predetermined period of time, a chip that may be bet, but may not be converted, or a coupon that may be used at the casino game arcade as the benefit. Therefore, for example, the point management unit 615 assigns the grant condition that the profit of the player in the predetermined period is equal to or less than the predetermined amount to the benefit such as the time limit chip that may be used after the predetermined period of time and the coupon that may be used at the casino game arcade. Of course, the grant condition is not set in the benefit, but the benefit may include a benefit which may be obtained only by consuming the point.
The member uses the membership card 1 in order to exchange the owned points into the benefit. The point management unit 615 acquires a request to change the points into the benefit and with reference to the recording unit 62, with respect to the required benefit, judges whether the owned points of the relevant member ID are sufficient for the number of consumption points corresponding to the benefit and whether to satisfy the grant condition when the grant condition is set.
When the owned points are sufficient and the grant condition is satisfied, the point management unit 615 updates the owned points by subtracting the number of points corresponding to the benefit from the owned points. The point management unit 615 rewrites the owned points of the recording unit 62 with the owned point updated by granting the benefit.
The benefit may be used at the casino game arcade, a related hotel, and a predefined facility. In the case of using the benefit in the casino game arcade, the benefit may be an entry right to a VIP room or substitute money for the game that may not be converted. In this case, the point management unit 615 may grant the entry right to the VIP room in exchange for a predetermined number of points and when the owned point is equal to or more than a predetermined value, the point management unit 615 may grant the substitute money for the game which may not be converted, which corresponds to the number of points. Further, when the benefit is used in the hotel, the benefit may be various services of the hotel.
The point management unit 615 may grant the benefit without consuming the point when granting to the member the benefit corresponding to the owned point. In other words, the status (rating) of the members may be set according to the owned point and the benefit corresponding to the status may be granted. Alternatively, the status may be granted instead of the point. In this case, the point management unit 615 confirms the owned point of the member who intend to receive the benefit and grants the benefit when the point are equal to or greater than a predetermined value. For example, a right to use the VIP room may be granted to a member whose owned point is larger than a predetermined threshold value.
Further, the point management unit 615 may output a cumulative bet amount for each game participant or the bet amount in a predetermined period as credit information of the game participant.
The minimum bet management unit 616 determines the minimum bet amount (or a recommendation value) of each game table 4 based on the game record acquired from the control device 14. By appropriately setting the minimum bet amount of the plurality of game tables 4 at the casino game arcade, the number of games, the number of players, and the bet unit price are optimized to enhance the sales. That is, in a predetermined game table 4, when a player (high-amount player) playing with a bet amount sufficiently higher than the minimum bet amount and a player (low-amount player) playing with the minimum bet amount or a bet amount slightly higher than the minimum bet amount coexist, the sales of the entire casino game arcade may be kept low.
When three low-amount players with a bet amount of approximately 1,000 dollars are added to the game table 4, the total bet amount of the game table 4 rises to approximately 1,3000 dollars, but as the number of players increases, the average time required for one game also increases. Assuming that the play time increases by 10 seconds each time one player increases, when the number of players reaches 4, the average time required for one game is 90 seconds. As a result, the sales per hour will decrease from approximately 600,000 dollars to approximately 520,000 dollars. As described above, since the high-amount player and the low-amount player coexist in the same game table, the sales of the house decreases even if the number of players increases.
In the example of
As described above, when the high-amount player is distributed in the plurality of game tables 4 and the high-amount player and the low-amount player coexist in each game table 4, the sales (in the case of
As in the above example, since the high-amount player and the low-amount player coexist in the game table 4 without appropriately setting the minimum bet amount, not only the sales of the house is reduced, but also the time required for one game increases in the high-amount player, and as a result, it is difficult to play the game comfortably.
Herein, the minimum bet management unit 616 sets an appropriate minimum bet amount of each game table 4 of the casino game arcade based on the game record sent from each control device 14.
The minimum bet management unit 616 sets the minimum bet amount of each game table 4 so as to increase the sales and the gross sales-versus-profit rate. Further, the minimum bet management unit 616 may set the minimum bet amount of each game table 4 so as to increase an average value of the number of games per unit time or the total bet amount per game.
In the minimum bet management unit 616, candidates of the minimum bet amount divided into a plurality of stages are set. In the embodiment, in the minimum bet management unit 616, five steps of minimum bet amount candidates of 100 dollars, 500 dollars, 1,000 dollars, 5,000 dollars, and 10,000 dollars are prepared. The minimum bet management unit 616 is set to select any one of the candidates of the minimum bet amount. Moreover, the minimum bet management unit 616 sets a more appropriate minimum bet amount in addition to the prepared candidates and when the minimum bet amount is inappropriate among predetermined minimum bet amount candidates, the minimum bet management unit 616 may more finely classify the minimum bet amount candidates.
The management device 60 outputs (transmits) the set minimum bet amount to the control device 14 of the game table 4. The control device 14 displays on the display 15 the minimum bet amount received from the management device 60. When receiving the minimum bet amount set from the management device 60, the control device 14 may display the recommendation value on the display 15 as it is or the control device 14 instructs only the dealer to display the recommendation value on the display 15 in accordance with the judgment and operation of the dealer.
Based on the information on the number of players in the game record and the information on the bet amount which is a minimum amount of the bet amount for each player position, or the information on the average bet amount in the game record, the minimum bet management unit 616 selects any one of the minimum bet amount candidates divided into the plurality of stages.
The minimum bet management unit 616 sets the minimum bet amount of each game table 4 by determining the total bet amount of each player for each game table 4, for each game and/or for each predetermined time or for each predetermined period. In the embodiment, the minimum bet management unit 616 raises the minimum bet amount when the number of players betting on the current minimum bet amount of the game table 4 at a predetermined rate or more is equal to or more than a predetermined ratio.
Specifically, the minimum bet management unit 616 rates, a player in which the minimum amount among the bet amounts of a predetermined number (five games in the embodiment) of games in the past is the predetermined ratio of the minimum bet amount (150% in the present embodiment) or more is rated as the high-amount player for each player position with respect to each game table 4. When the number of high-amount player is equal to or more than the predetermined ratio (50% in the embodiment) or more in the game table 4, the minimum bet management unit 616 sets the minimum bet amount which is higher than the previously set minimum bet amount in the game table 4.
In the example of
Meanwhile, in the example of
When raising the minimum bet amount, the minimum bet management unit 616 increases the minimum bet amount by one level and performs the same calculation as above. In the case of
In the above example, the minimum bet management unit 616 evaluates the minimum amount among the bet amounts of the past 5 games of the respective player positions (players), but instead of this, the minimum bet management unit 616 may rate a player in which the average value (average bet amount) of the bet amounts of the past predetermined number of games (for example, 5 games) is equal to or more than a predetermined ratio of the minimum bet amount (for example, 300%) as the high-amount player for each player position with respect to each game table 4.
Further, in the above example, when the number of high-amount players is equal to or more than the predetermined ratio, the minimum bet amount is changed to the amount higher by one level among the predetermined candidates, but instead of this, a predetermined ratio (for example, 150%) of the minimum bet amount, that is, in the example of
Next, determination of the recommendation value of the minimum bet amount according to the table congestion degree will be described. The minimum bet management unit 616 calculates the table congestion degree of each game table 4 based on the information on the number of players of the game record. Moreover, the table congestion degree indicates a ratio of the number of players participating in the game to a capacity of each game table 4. The minimum bet management unit 616 sets the minimum bet amount of each game table 4 according to the table congestion degree determined by the minimum bet management unit 616.
As shown in
In such a situation, the minimum bet management unit 616 raises to 10,000 dollars the minimum bet amount of the game table 4d in which the number of players participating in the game is smallest (table congestion degree is lowest) of the game tables 4c and 4d in which the minimum bet amount is 1,000 dollars. In doing so, as shown in
As described with reference to
In this way, the minimum bet management unit 616 determines the recommendation value of the minimum bet amount of each game table 4 so as to reduce the average number of players in the game in the game table 4 in which the minimum bet amount is high. Therefore, the minimum bet management unit 616 may lower the recommendation value of the minimum bet amount when the game table 4 with the number of participants in the game equal to or smaller than a predetermined number of persons is equal to or larger than a predetermined ratio.
As described above, in the example, the minimum bet management unit 616 manages a plurality of game tables 4 and determines the total bet amount for each of the plurality of game tables 4, for each game and/or for each predetermined time or for each predetermined period, and for each player to set different minimum bet amounts with respect to the plurality of game tables, respectively.
The minimum bet management unit 616 calculates the area congestion degree of each area when the casino game arcade is divided into a plurality of areas based on the information on the number of players determined by the control device 14 as a player number determination device. The area congestion degree is a ratio of the total number of players to the total number of player positions in the area. Moreover, the minimum bet management unit 616 may set the ratio of the game table 4 whose table congestion degree exceeds a predetermined value (for example, 80%) for each area as the area congestion degree.
The minimum bet management unit 616 determines all game tables 4 in the casino game arcade and the number of opened game tables 4 among them, and determines the recommended number of game tables 4 to be opened for each area according to the area congestion degree determined by the minimum bet management unit 616. Specifically, when the area congestion degree becomes equal to or greater than a predetermined value (80% in the embodiment), the minimum bet management unit 616 determines to newly open the game table 4 in the area.
When opening a new game table 4, the minimum bet management unit 616 sets the minimum bet amount of the game table 4. The minimum bet management unit 616 may simply set the same minimum bet amount as the minimum bet amount of the game table 4 around the newly opened game table 4 in the newly opened game table 4. As a result, customers are guided to the area to efficiently play the game.
Meanwhile, the minimum bet management unit 616 may set the minimum bet amount so that the sales of the house is maximized in order to newly open the game table 4.
In the case of
In the case of
In the case of
In this manner, the minimum bet management unit 616 determines the minimum bet amount of the newly opened game table 4 based on the minimum bet amount and the actual bet amount of the game table 4 around the game table 4. Further, as in the example of
The minimum bet management unit 616 manages the dealer who is at work and determines whether to open the new game table 4 according to the number of dealers. Specifically, even when the area congestion degree becomes high, when there are no dealer waiting (to be allowed to move) (that is, all dealers are on the game table 4) and when the game table 4 which may be newly opened disappears (that is, when all of the game tables 4 are opened), the minimum bet management unit 616 does not determine to open the new game table 4 and the minimum bet management unit 616 responds by changing the minimum bet amount of the already opened game table 4.
The minimum bet management unit 616 records the transition of the area congestion degree in the recording unit 62 for each area to determine the recommended number of game table 4 to be opened for each area based on the recorded transition information. That is, when the area congestion degree tends to increase, the minimum bet management unit 616 determines to open the new game table 4 before the area congestion degree reaches a predetermined value in the area.
As described above, in the example, the minimum bet management unit 616 manages a plurality of game tables 4 and determines the total bet amount for each of the plurality of game tables 4, for each game and/or, for each predetermined time or for each predetermined period, and for each player to set the minimum bet amount with respect to the newly opened game table.
The minimum bet management unit 616 records the bet amount and withdrawal/collection information included in the game record in the recording unit 62 in association with the member ID. In this way, the minimum bet management unit 616 records past play contents in the recording unit 62 for each player.
Based on the game record, the minimum bet management unit 616 further calculates with respect to each player the average bet amount, an average continuous play time in the same table, an absence rate when the minimum bet amount increases, a recent winning rate, the winning amount, etc. from the past play contents based on the game record, and stores them in the recording unit 62 as tendency information of each player in association with the member ID.
The minimum bet management unit 616 may determine the recommended number of game tables to be newly opened based on the tendency information of the plurality of players in the area recorded in the recording unit 62 for each area. Further, the minimum bet management unit 616 sets the minimum bet amount of the currently opened game table 4 based on the tendency information of the plurality of players in the area recorded in the recording unit 62 for each area or set the minimum bet amount of the newly opened game table 4.
That is, in the above description, it is assumed from the state of
The dealer accommodates the chips 9 collected from the losing player in the chip tray 17 and also withdraws the chips 9 from the chip tray 17 to the winning player. Therefore, the number of chips 9 in the chip tray 17 increases or decreases.
When many chips 9 are collected and may not be accommodated in the game table 4, the dealer calls a staff (pit manager) of a nearest pit to collect the chips 9. On the contrary, even if many chips 9 are withdrawn and the chips to be withdrawn in the game liquidation are insufficient, the dealer calls the staff of the nearest pit to replenish the chips 9.
When the dealer chip amount after liquidation in the game record sent from the control device 14 exceeds a predetermined upper limit threshold value and falls below a predetermined lower limit threshold value, the dealer chip management unit 617 notifies the nearest pit of the game table 4 of the effect. The notification includes at least the table number of the corresponding game table 4 and information indicating collection or replenishment.
As a result, the pit manager may collect or replenish the corresponding game table 4 according to the notification from the management device 60. Further, the dealer does not need to pay attention to the timing of calling the pit manager and may concentrate on dealing of the game.
As described above, according to the table game management system of the embodiment, by installing various sensors in each game table 4, the fraud or the mistake is automatically discovered and the fraud or the mistake is reduced, thereby increasing the gross profit of the house. Further, by statistically processing sensing data acquired for discovering the fraud and mistake, various analyses to increase the gross profit of the house are conducted and presented to the game organizer. This allows the game organizer not only to increase gross profit by reducing passive factors such as fraud and loss due to the mistake but also to increase the gross profit by strengthening more aggressive factors.
Moreover, in the embodiment, the management system 100 has a configuration including the plurality of control devices 14 installed for each game table 4 and the management device 60 connected to the plurality of control devices 14, but some or all functions of the control device 14 may be provided in the management device 60 or some or all functions of the management device 60 may be provided in the control device 14 of each game table 4. That is, the configurations and functions of the control device 14 and the management device 60 described above may be implemented by a device which may be provided in each game table 4 or a device which may be provided in places (for example, the backyard) different from the game table 4.
As described above, according to the third embodiment, in the game table 4, the bet contents are determined by the camera 2 and the control device 14 as the image recognition device, the game result is determined by the card distribution device 3, and the dealer amount is determined by the antenna and the RF reader and the information is intensively managed by the management devices 50 and 60, and as a result, it is possible to automatically determine the sales, the profit, the profit rate, etc. of a casino operator.
In the embodiment described above, the win or lose determination device is realized by the card distribution device 3, that is, the card distribution device 3 has a configuration of performing win or lose determination, but the win or lose determination may be performed by the control device 14. In this case, from the card distribution device 3, the information read out from the distributed card (card reading information) is transmitted to the control device 14, and the control device 14 determines the win or lose result of the game according to the game rule, on the basis of the card reading information from the card distribution device 3, as the win or lose determination device.
In addition, in the embodiment described above, the calculation unit 511 calculates the sales, the profit, and the profit rate, and the table creation unit 512 creates the table or the graph by adding up the calculated sales, profit, and profit rate, but instead thereof, a part or all of the adding-up may be performed by the calculation unit 511, and the table creation unit 512 may create the table or the graph by using the added-up result of the calculation unit 511.
