[Technical Field]

[0001] The present invention relates to a fraud monitoring system for table games in gaming facilities, and more particularly to a technology for detecting fraudulent activity. [Background technology]

[0002] Casinos and other gaming establishments are attempting to prevent various types of fraudulent activity. Gaming establishments are equipped with surveillance cameras to monitor for fraudulent activity, and images captured by the cameras are used to detect cheating in games and fraudulent withdrawals or redemptions of chips that do not correspond to the winning or losing results. On the other hand, it has been proposed to attach an IC tag to each chip to track the number of chips bet and the total amount.

[0003] The card game monitoring system described in Patent Document 1 monitors for fraudulent activity by determining whether chips placed on a gaming table have been collected or redeemed in accordance with the outcome of the game through image analysis of the movement of the chips.

Best Mode for Carrying Out the Invention

[0035] The outline of the illegal monitoring system 10 for table games in a casino will be described below with reference to the drawings. Here, table games include various table games such as baccarat, blackjack, poker, bridge, roulette, dice, etc. Below, the baccarat game will be taken as a representative example for explanation.

[0036] FIG. 1 and FIG. 2 are diagrams showing the whole of the illegal monitoring system 10. The gaming table 4 is a table for baccarat, and each bet area 44 for seven game participants 6 is provided. Each bet area 44 of each game participant 6 includes areas for PLAYER 441, BANKER 442, TIE 443, PLAYER PAIR (P) 444, and BANKER PAIR (B) 445. Each game participant 6 makes a bet by placing gaming tokens 9 of the amount to be bet in each area corresponding to the object of the bet.

[0037] In the gaming table 4, a win / loss determination device for determining the win / loss result of each game uses a card distribution device 3. The card distribution device 3 is a so-called electronic shoe already used by those skilled in the art, in which the rules of the game are programmed in advance, and it has a structure capable of reading the information of the dealt playing cards and determining the win / loss of the game. For example, in the baccarat game, the win of the banker, the win of the player, a tie (draw), and a pair (the ranks of the player's or banker's hand are the same) are basically determined by the ranks of 2 - 3 cards, and the determination result (win / loss result) is displayed on the result display lamp 13. Also, the card distribution device 3 sends the determined win / loss result of the game to the management control device 50.

[0038] However, as another embodiment, instead of the card distribution device 3, the dealt playing cards may be recognized by an image by a camera device 2 to determine the win / loss, and it may be used as a win / loss determination device.

[0039] The camera device 2 is provided above the gaming table 4 and photographs the bet area 44. The gaming table 4 of the present embodiment is provided with seven player positions 45 (the "1", "2", "3", "5", "6", "7", "8" in FIG. 1), and seven game participants 6 can participate in the game. The camera device 2 photographs the bet areas 44 of all the player positions 45. Note that it is not necessary for one camera device 2 to photograph the bet areas 44 of all the player positions 45, and a plurality of camera devices 2 may be used to share the task of photographing all the bet areas 44.

[0040] The gaming substitute currency 9 has markings, patterns, and / or colors on its surface and / or side surfaces that can identify its type (value). The bet chip measuring device 19 identifies the position (bet target), type, and number of gaming substitute currency 9 placed in the bet area 44 based on the color of the edge on the side surface of the gaming substitute currency 9 in the image photographed by the camera device 2. At this time, the bet chip measuring device 19 may be configured to use an existing artificial intelligence-utilizing computer or control system, deep learning (structure) technology, and self-learning functions to recognize situations where the gaming substitute currency 9 is hidden due to blind spots (when a part of a single chip is hidden or when the entire chip is hidden), so as to accurately grasp the position and number, etc.

[0041] Furthermore, as shown in FIG. 4, the gaming substitute currency 9 may have a structure in which a plurality of plastic layers of different colors are laminated, with at least a colored layer 121 in the middle, and white layers or light-colored layers 120 are laminated on both sides of the colored layer 121 to form a stripe pattern in the lamination direction on the side surface, and the type of the gaming substitute currency 9 can be identified by the colored layer. In this case, the type of the gaming substitute currency 9 (10 points, 20 points, 100 points, 1000 points, etc.) can be identified by changing the color of the colored layer 121 (such as red, green, yellow, or blue).

[0042] In such a case, as shown in FIG. 4 (compared with the conventional chip shown in FIG. 2), it has a laminated multi-layer structure, and distinct stripe patterns in the stacking direction are formed on the side surface. Therefore, the bet chip measuring device 19 can easily and accurately measure the type and number of the gaming substitute coins 9.

[0043] Alternatively, the structure for detecting the position 8 and type in the betting area 8 of the gaming substitute coins 9 is not limited to this. For example, as shown in FIG. 3, an RFID 125 storing information capable of specifying at least its type is embedded in the gaming substitute coin 9, and an RFID antenna (not shown) installed on the gaming table 4 reads the ID to detect and specify the position (bet target), type, and number of the gaming substitute coins 9 placed in the bet area 44.

[0044] In front of the dealer 5 on the gaming table 4, a gaming substitute coin tray 17 for the dealer 5 to store the gaming substitute coins 9 is provided. At least a part of the gaming substitute coin tray 17 is embedded in the gaming table 4. In the gaming substitute coin tray 17, the bet chip measuring device 19 analyzes and measures the gaming substitute coins 9 stacked in the horizontal direction, and thus the type and number of the gaming substitute coins 9 can be determined. Also in this case, the bet chip measuring device 19 may specify the position (bet target), type, and number of the gaming substitute coins 9 stored in the gaming substitute coin tray 17 from the color of the edge on the side surface of the gaming substitute coins 9 based on the image captured by the camera device 2. Or, for example, as shown in FIG. 3, an RFID 125 storing information capable of specifying at least its type is embedded in the gaming substitute coin 9, and an RFID antenna (not shown) installed on the gaming table 4 reads the ID to detect and specify the position (bet target), type, and number of the gaming substitute coins 9 stored in the gaming substitute coin tray 17.

[0045] The management control device 50 grasps the position, type, and number of the gaming tokens 9 on the gaming table 4 obtained by the bet chip measuring device 19, and has a function of calculating the casino's revenue and expenditure on the gaming table 4 using the win / loss result obtained from the card distribution device 3 as a win / loss determination device. The management control device 50 stores the number of games played on the gaming table 4, and for each game, using the measurement result of the bet chip measuring device 19, it identifies and stores the position and amount of the gaming tokens 9 placed on the gaming table 4 by the game participants 6 for each game participant 6 or player position 45 of the gaming table 4.

[0046] Furthermore, the management control device 50 has a calculation function of performing the settlement amount (calculation of the casino's revenue and expenditure on the gaming table 4) for each game. After the total amount of the gaming tokens 9 in the gaming token tray 17 of the dealer 5 on the gaming table 4 is settled with the gaming tokens 9 bet by each game participant 6 after each game, it has a structure capable of comparing and calculating whether the increase or decrease of the gaming tokens corresponding to the settlement is correct. The management control device 50 can always (or at a predetermined time interval) verify the total amount of the gaming tokens 9 in the gaming token tray 17.

[0047] The management control device 50 stores the total number of games participated by the same person for each game participant 6 or player position 45, the transition of the bet chip amounts for each game, and the return amounts obtained in each game. The return amount is the amount of money obtained by the game participant 6 as a result of the bet. Based on the total number of games, the transition of the bet chip amounts for each game, and the return amounts obtained in each game, the management control device 50 calculates the winning rate at the end of each game as shown in FIG. 7, aggregates the return amounts obtained in each game, and obtains the results of the actual winning rate and total return amount for each game participant 6 or player position 45 of the same person when a predetermined number of games are completed. The management control device 50 compares the obtained actual winning rate and total return amount with the numbers in probability statistics calculations to determine whether there is a significant difference between the two, and has a calculation function of identifying any one of the game participant 6 or player position 45 where a significant difference occurs, or the gaming table 4, or the room where the gaming table 4 is placed.

[0048] Specifically, the management control device 50 may determine that there is a significant difference when, for example, the ratio of the winning rate to the number of games is higher than a predetermined threshold compared to the number obtained by probability statistical calculation, or when the ratio of the total return amount to the number of games is higher than a predetermined threshold compared to the number obtained by probability statistical calculation, or when the ratio of the total return amount to the winning rate is higher than a predetermined threshold compared to the number obtained by probability statistical calculation, or when the total return amount obtained by one person is higher than a predetermined threshold compared to the number obtained by probability statistical calculation, or may determine that there is a significant difference according to other criteria.

[0049] FIG. 5 shows an overall view of a room having a plurality of gaming tables 4. The management control device 50 stores the total number of games, the transition of the bet chip amount for each game, and the return amount obtained in each game for each person of the same person for each game participant 6 or player position 45 of each of the plurality of gaming tables 4, and obtains the winning rate and the total return amount. The management control device 50 may further store the total number of games, the transition of the bet chip amount for each game, and the return amount obtained in each game for each gaming table 4 and for each room, and obtain the winning rate and the total return amount. By doing so, it is possible to detect collusive cheating across the entire gaming table or the entire room.

[0050] The management control device 50 may further have a function of identifying the dealer 5 in each gaming game, and may have a function of identifying the dealer 5 in charge of a series of games in which the significant difference occurs. In addition, the management control device 50 stores the total number of games, the transition of the bet chip amount for each game, and the return amount obtained in each game for each dealer 5, and can obtain the winning rate and the total return amount, and detect a dealer 5 highly likely to be leading the cheating.

[0051] FIG. 6 is a diagram showing the transition of the total return amount of each game participant 6 over time. By comparing with the data obtained by probability calculation, past statistical data, or comparing among the game participants 6, it is possible to detect a game participant 6 highly likely to be cheating.

[0052] The management control device 50 has a computing function that factorizes the total return amount in a series of games in which a significant difference has occurred, and identifies whether the cause of the significant difference in the series of games in which the significant difference has occurred is due to the winning rate or the amount of the bet chips. That is, whether the total return amount is large because the same amount of money is bet both when winning and when losing, and simply the probability of winning is high, or whether the probability of winning is not so high, but a large amount of money is bet when winning and a small amount of money is bet when losing, can be determined.

[0053] Furthermore, the management control device 50 stores the bet chip amounts of each gaming game at bet positions with different return multiples, and has a computing function that identifies whether the cause of the significant difference in a series of games in which the significant difference has occurred is related to bet positions with different return multiples. For example, in baccarat, the return multiple is 2 times for player / banker, 8 times for tie, and 11 times for pair. Therefore, it is possible to detect a betting method of winning only with a betting method with a high return multiple such as tie or pair, which has a high possibility of being an illegal act. In particular, tie is well-known as an illegal act because it is established if 10 or picture cards (J, Q, K) are consecutive.

[0054] Furthermore, the management control device 50 has a plurality of criteria for determining whether there is a significant difference, and issues different types of warnings for each criterion. For example, if the detected significant difference is a significant difference that can occur about once every three days, a first-stage warning is issued; if the detected significant difference is a significant difference that can occur about once a week, a second-stage warning is issued; if the detected significant difference is a significant difference that can occur about once a month, a third-stage warning is issued. When an illegal act is detected, the abnormal display lamps 16 provided on both the win / loss determination device 3 and the gaming table 4 are lit, and the detection of the illegal act is output 15 wirelessly / wiredly to the casino management department or the like. A monitor or lamp for issuing a warning or display in response to the determination result may be provided in another place. Also, the configuration may be such that the VTR recorded by the camera device 2 can be played back when a warning is received.

[0055] Figure 7 is a graph showing the change in the winning rate of game participant 6 for each number of games. For example, in this case, the winning rate is high in the 100th to 200th games, but since the number of games is small, it is within the range that can occur in probability calculations, so a warning is issued at the first stage. After that, since the winning rate is decreasing, the warning disappears once, but the winning rate rises again at the 1000th game. In this case, since the winning rate is high despite the large number of games, it is an event that is unlikely to occur in probability calculations, and a warning is issued at the third stage.

[0056] Furthermore, the management control device 50 has different significance difference determination criteria for each number of games delimited by a predetermined rule or for each predetermined number of games, and issues different types of warnings. For example, in a table game using shuffle playing cards such as baccarat, shuffle playing cards for 8 to 10 decks are shuffled and stored in a box, and the shuffle playing cards are set in the card distribution device 3 to play the game. Figure 8 shows a graph in which the data of the winning rates are tabulated for each box (referred to as a shoe) of the shuffle playing cards used in the game (Shoe 1S, Shoe 2S, Shoe 3S). By this, it is possible to detect illegal acts such as knowing the order within a specific box of shuffle playing cards, which cannot be detected by simply monitoring the overall winning rate. In the graph continuously monitoring the overall winning rate in the upper part of Figure 8, the winning rate is high at first and then seems to have no characteristics. However, looking at the graph divided by shoe in the lower part of Figure 8, it can be detected that the winning rate is high in Shoe 3S, indicating a high possibility of illegal acts. Also, the graphs of the same winning rate in Shoe 1S and Shoe 3S can be seen, indicating a high possibility of illegal acts.

[0057] Furthermore, the management control device 50 determines whether there is a significant difference for each game sequentially as the plurality of games progress, or for each elapse of a predetermined number of games, and issues a warning when the stage exceeds the significance difference determination criteria. For example, even if the winning rate is 70% when 50 games are played, it is difficult to determine that there is a significant difference, but if the winning rate is 70% after 500 games are played, it is determined that there is a significant difference, and the suspicion of illegal acts increases.

[0058] The management control device 50 can calculate the occurrence probability for each game unit and determine whether there is a significant difference. If each game unit is, for example, 75 game units, it calculates the probability that the results of the 1st to 75th times are consecutive, and then sequentially calculates the probability that the results of the 2nd to 76th games are consecutive, and outputs a warning when the occurrence probability exceeds the determination criterion of the significant difference. The game unit is not limited to 75 games, and may be game units such as 100 games or 300 games. In addition, the management control device 50 can calculate the occurrence probability for each bet type and for each box number.

[0059] Furthermore, the management control device 50 has a plurality of criteria for determining whether there is a significant difference, identifies the game participants 6 or player positions 45 having the possibility of fraud for each criterion, scores them for different criteria, and can display the warning as a score display or a rank display.

[0060] Furthermore, the management control device 50 can perform the numerical values in the probability statistical calculation used to determine whether there is a significant difference by using conditional probability calculation when specific elements are fixed values. For example, with the number of games fixed, it may be calculated using conditional probability calculation.

[0061] The management control device 50 further has a function of sequentially grasping the numbers shown on the playing cards or the dice in a series of games, speculates on the cause of fraud when it is determined that there is a significant difference based on the data of the numbers shown in a series of games, and can list the possible causes of fraud. For example, if it is found that when the number of the playing card drawn first is 9, the player wins based on the data of the numbers shown in a series of games, it can be speculated that the position of the playing card with the number 9 being known is the cause of fraud.

[0062] Furthermore, the management control device 50 may speculate on the cause of fraud when it is determined that there is a significant difference by using either or both of the big data related to past games and the data of past frauds, and list the possible causes of fraud.

[0063] In addition, the management control device 50 calculates the total number of games played on each gaming table 4 and the trends of the casino's income and expenses in each game, and based on these calculations, when a predetermined number of games is completed, it compares the result of the casino's income or expense amount with the numbers in probability and statistical calculations to determine whether there is a significant difference between the two, and may have a computing function to identify either the gaming table 4 where a significant difference has occurred or one of the rooms where the gaming table 4 is located. In this case, it is not necessary to know the bet amount for each game participant 6, and it is only necessary to know the balance of the gaming substitute currency tray.

[0064] Furthermore, the table game fraud monitoring system may further include a device for identifying the game participant 6 of the gaming table 4 from information such as a face recognition system or the ID card, credit card, etc. used.

[0065] In the case of a face recognition system, an image of the face is obtained by feature point extraction or the like, and an identity number (ID, etc.) is attached for identification. When the identified game participant 6 leaves and arrives at another gaming table, it has a warning function to notify the presence of the specific player at the other gaming table. Specifically, it can warn the pit manager who manages each gaming table 4 and each table supervisor.

Typically, the occurrence of a winning amount of a certain amount (one million dollars) or more, or at a play position 7 on a certain gaming table 4, a state where the amount of bet chips when losing is small and the amount of bet chips when winning is large continues for several games, and this can be extracted as a special situation compared with the statistical data (big data, etc.) of past games. It is equipped with a management control device 50 of an artificial intelligence utilization type or deep learning structure. Furthermore, the management control device 50 can identify what the cause of the illegal act is compared with the statistical data of past games.

[0068] Since the management control device 50 has artificial intelligence taught with the data of past illegal games as teacher data, it can detect new types of illegal acts detected by the artificial intelligence.

[0069] When it is determined that there is a significant difference, the management control device 50 speculates on the cause of the illegality using the big data related to past games as additional items, and lists the possible causes of the illegality.

Based on these calculations, at the time when a predetermined number of games have ended, it is determined whether there is a significant difference indicating a possibility of fraud in any one of the game participant 6 or player position 45, the gaming table 4, or the room where the gaming table 4 is located. It is equipped with a computer function for this purpose.

[0071] In yet another embodiment of the present invention, a table game fraud monitoring program includes a win / loss determination step of grasping the win / loss result of each game on the gaming table 4, a bet chip grasping step of grasping the amount of gaming substitute currency 9 bet by the game participant 6 on the gaming table 4 in each game, a game progress grasping and management step of storing the number of games played on the gaming table 4 and specifying and storing the betting pattern of the gaming substitute currency 9 placed by the game participant 6 on the gaming table 4 for each game participant 6 or player position 45 of the gaming table 4 using the trend data of the bet chips in the bet chip grasping step for each game, and a fraud occurrence possibility verification step. The fraud occurrence possibility verification step grasps the total number of games participated by the same person for each game participant 6 or player position 45, the trend of the bet chip amount, and the return amount for each game, and uses these as the basis for calculation. At the time when a predetermined number of games have ended, it includes a step of calculating the actual winning rate of the same person for each game participant or player position and a step of calculating the total return amount, a significant difference determination step of comparing the obtained winning rate and total return amount with the winning rate and total return amount based on probability statistics calculation or past data in a predetermined number of games to determine whether there is a significant difference between the two, and an abnormal location determination step of specifying any one of the game participant or player position where a significant difference has occurred, the gaming table, or the room where the gaming table is located.
