BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a game management system for managing a game, which is played on a game table and employs a plurality of cards and chips.
2. Related Background Art
In games employing a plurality of cards and chips, for example, the cards are exchanged between a dealer and players facing each other over a game table, and the chips according to bets are exchanged between the players through the dealer. A casino hotel is known as an establishment for playing such card games. In a casino hotel, a guest who has received a house card (e.g., an ID card on which an identification number is recorded to prove him/herself) upon check-in, in other words, a user of the casino hotel can utilize the house card to use different facilities in the hotel. The house card is read out at the cashiers in restaurants and bars in the hotel so that the bills are stored in a hotel server. Upon check-out, all the bills are displayed on the terminal at the front desk. In addition, the house card can be utilized in transportation outside the hotel during a stay by connecting the transportation to the hotel via network.
SUMMARY OF THE INVENTION
Incidentally, a game charge at a casino is billed separately in conventional casino hotels. Accordingly, the aforementioned house card cannot be utilized to play games. In this case, there is a problem that the hotels cannot provide obliging service to their guests. It is because types of games played at a casino and money spent for the games cannot be recorded onto a history from upon check-in until check-out.
The present invention has been devised to solve the problem. An object of the present invention is to provide a game management system capable of collectively managing the tracks and the results of the games played by the user.
In order to achieve the object, the game management system of the present invention for managing a game, which is played on a game table and employs a plurality of cards and a plurality of chips, includes: (a) card identification information recording means for recording card identification information for identifying each of the plurality of cards, the card identification information recording means being provided with each of the plurality of cards; (b) chip identification information recording means for recording chip identification information for identifying each of the plurality of chips, the chip identification information recording means being provided with each of the plurality of chips; (c) first identification information detecting means for detecting the card identification information recorded on the card identification information recording means provided with each of the plurality of cards, the first identification information detecting means being provided with the game table; (d) second identification information detecting means for detecting the chip identification information recorded on the chip identification information recording means provided with each of the plurality of chips, the second identification information detecting means being provided with the game table; (e) individual identifying means for acquiring personal information for identifying a participant in the game, the individual identifying means being provided with the game table; and (f) managing means for managing tracks and results of the game played on the game table in association with the personal information, which is acquired by the individual identifying means, based on the card identification information detected by the first identification information detecting means and the chip identification information detected by the second identification information detecting means.
According to the present invention, the individual identifying means provided with the game table recognizes the personal information concerning the participant in the game. In other words, the individual identifying means recognizes the user of the facility. The first and second identification information detecting means provided with the game table recognize the cards and the chips used by the participant during the game respectively. Therefore, the managing means can collectively manage the tracks and the results of the game played on the game table in association with the personal information.
In the game management system of the present invention, information concerning the cards at the beginning of the game and a movement history of the cards during the game can be included as the track of the game. It is possible to include information on the cards remaining at the end of the game as the result of the game. Kinds and the number of cards dealt at the beginning of the game can be included as the information concerning the cards at the beginning of the game. It is possible to include kinds and the number of the remaining cards at the end of the game as the information on the cards remaining at the end of the game.
In the game management system of the present invention, information concerning the chips bet at the beginning of the game and a movement history of each of the chips during the game can be included as the track of the game. It is possible to include information concerning the remaining chips at the end of the game as the result of the game. Kinds and the number of chips bet at the beginning of the game can be included as the information concerning the chips bet at the beginning of the game. Kinds and the number of the remaining chips at the end of the game can be included as the information concerning the chips remaining at the end of the game.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Hereinafter, a game management system according to an embodiment of the present invention is described with reference to the accompanying drawings. FIG. 1 shows a configuration of a casino/hotel system according to an embodiment of the present invention.
A plurality of servers, terminals, and the like are connected via network to construct the casino/hotel system 1. These servers, terminals, and the like have functions as described below in the casino/hotel.
Various functions for general management of a terminal 4a of a front desk 4, cashiers 6a and 8a of a restaurant 6 and a bar 8, and the like are constructed in a hotel server 2. Various functions to reserve and issue tickets for a variety of shows and events in a hotel are constructed in the service server 10. A function to manage the intranet in the hotel is constructed in an intra-service server 12. A function to comply with a video-on-demand and a game-on-demand at a set-top box 16a in a room 16 is constructed in a multimedia server 14.
Various functions to manage an ID card 20 called a house card (card which can identify a guest staying at the hotel), a personal account, and the like are constructed in a house card server 18.
A guest who checked in a casino/hotel, namely a user, is issued with the ID card (house card) 20 to identifying the user by a card issuing machine 4b of the front desk 4. Information for identifying the user of the casino/hotel is recorded on the ID card 20. In the present embodiment, information which can identify an individual user (user ID) is recorded on the ID card 20. Note that the ID card 20 may be distributed to each room in the hotel. In this case, ID assigned to each room in the hotel is recorded on the ID card 20.
The user who acquired the ID card 20 can utilize all the facilities in the casino hotel by showing the ID card 20 to be checked. For example, at the cashiers 6a and 8a of the restaurant 6 and the bar 8 in the hotel, the ID card 20 is read out by card reader 6b and 8b so that bills are stored on the hotel server 2. Accordingly, all the bills are displayed on the terminal 4a of the front desk 4 upon check-out. In other words, the ID card 20 can be linked to various management systems in addition to the undermentioned game management system and has at least a function as a credit card to pay for goods as well as meals and drinks.
Various functions are constructed in this game management system of the casino/hotel system 1 to manage different games played on each of game tables 24 in a casino 22. FIG. 2A is a view showing the configuration of the game table 24. In the following description, a card game employing the plurality of cards 26 and chips 28 is played on the game table 24 as shown in FIG. 2A.
This game management system is constructed by resonant tags (card identification information recording means) provided on the plurality of cards 26, a micro wireless ID tag (chip identification information recording means) 44 provided on each of the plurality of chips 28, first identification information detectors (first identification information detecting means) 30, second identification information detectors (second identification information detecting means) 46, a PTS server 66, an accumulation/analysis server 68, and a casino deposit server 72. Herein, the PTS server 66, the accumulation/analysis server 68, and the casino deposit server 72 correspond to the managing means of the present invention.
FIG. 2B is a view showing the configuration for detecting card identification information of cards. In the present embodiment, the plurality of cards 26 are presumed to be a deck of playing cards, which includes 54 cards. The card identification information to identify individual cards is recorded on the plurality of cards 26. In the present embodiment, a resonant tag is provided on each of the cards 26 to record the card identification information for each of the plurality of cards (playing cards) 26. For example, as shown in FIG. 2B, at least two resonant tags (resonant tags T1, T2, and T3 on the ace of hearts of a playing card 26a, and resonant tags T1, T3, and T7 on the ten of hearts of a playing card 26b) are disposed on each of the playing cards 26 (refer to 26a and 26b). In this case, the card identification information on each of the playing cards 26 is configured by a combination of at least two resonant tags. By detecting echo waves (F1, F2 F3, and F1, F3, F7) transmitted from these resonant tags, it is possible to identify specific playing cards (26a and 26b) from the plurality of playing cards.
As shown in FIGS. 2A and 2B, the first identification information detectors 30 for detecting the card identification information are provided in the vicinities of a dealer D and participants P1, P2, and P3 in the game on the game table 24.
The first identification information detector 30 has a transmitter 32, a frequency register 34, a transmitter controller 36, a card frequency register 38, a receiver 40, and an analysis collation unit 42.
The transmitter 32 transmits electromagnetic waves (W1, W2, W3, W4, W5, W6, W7, and W8) to the plurality of playing cards 26 (26a, 26b) so that the plurality of resonant tags (e.g., T1, T2, T3 and T1, T3, T7) transmit echo waves (F1, F2, F3 and F1, F3, F7).
The frequency register 34 sets frequencies (f1, f2, f3, f4, f5, f6, f7, and f8) of the electromagnetic waves (W1, W2, W3, W4, W5, W6, W7, and W8) to register. The transmitter controller 36 makes the transmitter 32 to transmit the electromagnetic wave corresponding to each of the frequencies registered in the frequency register 34.
The card frequency register 38 selects combinations of at least two of the frequencies registered in the frequency register 34 (e.g., f1, f2, f3 and f1, f3, f7). Thereafter, the card frequency register 38 associates the selected combinations of at least two frequencies to the plurality of playing cards 26 (26a and 26b) respectively to register.
The receiver 40 receives the echo waves (F1, F2, F3 and F1, F3, F7) transmitted from the plurality of resonant tags (T1, T2, T3 and T1, T3, T7) when the electromagnetic waves (W1, W2, W3, W4, W5, W6, W7, and W8) are transmitted from the transmitter 32.
The analysis collation unit 42 analyzes each of the frequencies (f1, f2, f3 and f1, f3, f7) of the echo waves (F1, F2, F3 and F1, F3, F7) received by the receiver 40 based on the frequencies (f1, f2, f3, f4, f5, f6, f7, and f8) registered in the frequency register 34. The analysis collation unit 42 collates the combinations of the analyzed frequencies (f1, f2, f3, and f1, f3, f7) with the combinations of the frequencies of the plurality of playing cards 26 (26a and 26b) registered in the card frequency register 38 to identify the cards.
In order to identify kinds of the 54 playing cards at a minimum number of resonant tags, eight resonant tags, which transmit echo waves with different frequencies, are required. In this case, three resonant tags are combined (8C3=56) to be disposed on each of the playing cards. Alternatively, when eleven resonant tags are used, two resonant tags are combined (11C2=56) to be disposed on each of the playing cards.
Suppose the case where three resonant tags are combined to be disposed on each of 54 playing cards by using eight resonant tags (only T1 T2, T3, and T7 are shown in the drawing, but T1 to T8 are employed in the actual case). In this case, eight frequencies (f1, f2, f3, f4, f5, f6, f7, and f8) to excite the eight resonant tags are registered with the frequency register 34 of the first identification information detector 30. The card frequency register 38 selects combinations of three of the eight frequencies registered with the frequency register 34. Thereafter, the card frequency register 38 associates the combinations of three selected frequencies with each of the playing cards to register. For example, frequencies (f1, f2, f3) are associated with the ace of hearts, and frequencies (f1, f3, f7) are associated with the ten of hearts. In this case, when the frequencies of the echo waves transmitted from the three resonant tags are (f1, f2, f3), the analysis collation unit 42 identifies the card as the ace of hearts. When the frequencies of the echo waves transmitted from the three resonant tags are (f1, f3, f7), the analysis collation unit 42 identifies the card as the ten of hearts.
Chip identification information to identify the chips is recorded on each of the plurality of chips 28. FIG. 2C is a view showing the configuration for detecting chip identification information on a chip. In the present embodiment, as shown in FIG. 2C, a micro wireless ID tag 44 is embedded in each of the plurality of chips 28. The chip identification information to identify the chip is recorded on the micro wireless ID tag 44. A value ($1, $5, $10 or the like), an intrinsic number (a number for identifying the chip), and the like of the chip 28 are registered with the micro wireless ID tag 44. The second identification information detectors 46 which detect the chip identification information recorded on the micro wireless ID tag 44 are provided in the vicinities of the dealer D and the participants P1, P2, and P3 on the game table.
An ID readout device and a chip weighing device 60 constitute the second identification information detector 46. X transmitting and receiving antennas 50 and 52 and Y transmitting and receiving antennas 56 and 58 are perpendicularly disposed to constitute the ID readout device. The X transmitting and receiving antennas 50 and 52 extend from an X scan driver 48 parallel to each other. The Y transmitting and receiving antennas 56 and 58 extend from a Y scan driver 54 parallel to each other.
According to the ID readout device, electric waves are generated in the vicinities of the cross points of the antennas when scanning electric waves are transmitted from the X and Y transmitting antennas 50 and 56 while the chip 28 is bet on the game table 24 (the second identification information detector 46). These electric waves are received by the X and Y receiving antennas 52 and 58. However, when the chip 28 is bet in the vicinities of the cross points, impedance varies due to the dielectric chip 28. As a result, reception of the electric waves changes at the X and Y receiving antenna 52 and 58. By detecting the change in the reception of the electric waves, the presence of the chip 28 is determined. Simultaneously, the X and Y receiving antennas 52 and 58 receive signals from the micro wireless ID tag 44, the kind ($1, $5, $10 or the like), the intrinsic number (number for identifying the chip) and the like of the chip 28 are read out.
The chip weighing device 60 is disposed to cover the betting area. An electric weighing instrument such as a semiconductor pressure sensor, for example, can be used as the chip weighing device 60. Weight per chip is recorded on the chip weighing device 60. Consequently, it is possible to calculate the number of bet chips 28 by dividing the total weight by the weight per chip.
In this game management system, users who wish to play a card game at the casino 22 (refer to FIG. 1) obtain the desired number of chips 28 at the chip issuing/adjusting machine 62 when the users enter the casino with the aforementioned ID card 20. The users who obtained the chips 28 set the ID cards 20 at the readout unit 64 of the game table 24. The readout unit 64 reads out the contents of the ID cards 20, in other words, the user IDs recorded on the ID cards 20 to identify the users. Thus, the readout unit 64 recognizes the users as the participants in the game.
Data recognized by the readout section 64, in other words, the user IDs are sent to the PTS (Player Tracking System) server 66 and registered as participants (P1, P2, and P3) in the present game. Note that the readout process can be arbitrarily set (magnetic or optical readout process) in accordance with the recording method (magnetic or optical recording) of the ID cards 20.
The PTS server 66, the accumulation/analysis server 68, and the casino deposit server 72 are server devices physically comprising CPU (Central Processing Unit), a memory device such as a memory, data storage device such as a hard disk, and a communication device or the like for connecting to the hotel/casino system 1 via network, respectively.
The PTS server 66 manages tables for registering data including all the histories of the cards and all the histories of the chips at the game table. The accumulation/analysis server 68 accumulates and analyzes data including all the histories of the cards and all the histories of the chips, which are registered with the PTS server 66.
FIG. 3A is a view showing an example of a table managed by the PTS server regarding all the histories of the cards. As shown in FIG. 3A, when the dealer D deals the cards (playing cards) 26 at the beginning of the game, the first identification information detector 30 detects the kinds and the number of playing cards 26. Data (the kinds and the number of the playing cards 26) detected by the first identification information detector 30 is transmitted to the PTS server 66. During the game, the first identification information detector 30 sequentially detects the movement history of the playing cards 26 exchanged between the dealer D and the participants P1, P2, and P3. This detected data is transmitted to the PTS server 66. Specifically, the movement paths and the movement directions of the playing cards 26 are easily and accurately detected and registered with the PTS server 66 only via the first identification information detector 30 of the game table 24. At the end of the game, the first identification information detector 30 detects the kinds and the number of the remaining playing cards 26. This detected data is transmitted to the PTS server 66. As a result, all the tracks of the playing cards 26 in the card game are sequentially registered with the table managed by the PTS server 66 and managed by the accumulation/analysis server 68 collectively.
FIG. 3B is a view showing an example of a table managed by the PTS server regarding all the histories of the chips. As shown in FIG. 3B, the chips 28 bet during the card game are constantly detected by the second identification information detector 46 (ID readout device). The values of the chips 28 ($1, $5, $10 or the like), in other words, the kinds, the intrinsic numbers (number for identifying the chips), and the like are read out. At the same time, the chip weighing device 60 calculates the number of bet chips 28 accurately. All of these data (the kinds, the intrinsic numbers, and the number of the bet chips) are sequentially transmitted to the PTS server 66 and registered with the table managed by the PTS server 66 from the beginning until the end of the game. The accumulation/analysis server 68 refers the data including the kinds, the number, and the like of remaining chips 28 at the end of the game, which are registered with the PTS server 66. Thus, it is possible to calculate the total amount of remaining money accurately in a short period of time. Therefore, all the tracks of the chips are sequentially registered with the PTS server 66 and managed by the accumulation/analysis server 68 collectively.
FIGS. 4, 5A to 5C and 6 are views showing tables of another example, which are managed by the PTS server 66. These drawings show tables managed by the PTS server 66 when poker is played as the game.
FIG. 4 is a view showing an example of a table managed by the PTS server regarding the results of games. A game table ID, a game start time, a game end time, an investment, a return, and a fraud detection flag are registered with the table shown in FIG. 4 in association with the user ID read out from the ID card 20. Once the participant places the ID card 20 on the readout unit 64 when participating the game at the game table 24, the user ID read out from the ID card 20 by the readout unit 64 is registered with the table as shown in FIG. 4. At this time, the user ID is registered in association with a history number, which is automatically numbered. In the example shown in FIG. 4, the name of the user is registered as the user ID, such as “Taro Aruze.” Moreover, the game start time and the game table ID for identifying the seat at the game table are registered in association with the user ID.
FIGS. 5A, 5B, and 5C are views showing the tables of an example, with which the histories of the playing cards 26 used in the game are registered. FIG. 5A shows a table regarding the playing cards 26 dealt for the participants in the game at the beginning of the game. FIG. 5B shows a table regarding the movement histories of the playing cards 26 during the game. FIG. 5C shows a table regarding the remaining playing cards 26 at the end of the game.
A game number, which is automatically numbered, is registered with each of the tables shown in FIGS. 5A, 5B, and 5C for each poker game. As shown in FIG. 5A, the game table ID for identifying the seat at the game table, the number of playing cards (“NUMBER OF CARDS” in the drawing) at the beginning of the game, the kinds of the playing cards 26 (“CARDS 1 to 5” in the drawing), and the dealt time thereof (“TIME” in the drawing) are registered with the tables at the beginning of the game in association with the game number.
As shown in FIG. 5B, the movement tracks of the playing cards 26 (“MOVEMENT HISTORIES OF CARDS” in the drawing) as well as the game table ID and the movement time (“TIME” in the drawing) are registered with the tables in association with the game number during the game. Referring to FIG. 5B, it is recorded that the two of clubs was exchanged for the three of clubs as a first data of the table. In addition, it is recorded that the five of clubs was exchanged for a counterfeit card which was unrecognizable by the first identification information detectors 30 as a second data of the table.
As shown in FIG. 5C, the number of playing cards 26 at the end of the game (“NUMBER OF CARDS” in the drawing), the kinds of the remaining playing cards 26 at the end of the game (“CARDS 1 TO 5” in the drawing) as well as the game table ID and the end time of the game (“TIME” in the drawing) are stored in association with the aforementioned game number at the end of the game. Referring to FIG. 5C, it is recorded that five cards were remained at the end of the game as a first data of the table. In addition, it is recorded that four cards and a counterfeit card were remained for at the end of the game as a second data of the table.
FIG. 6 is a view showing an example of a table managed by the PTS server regarding the chips 28. In the example shown in FIG. 6, the aforementioned game number is registered with the table for each poker game. The number of bet chips 28 as well as a bet time are registered with the table in association with the game number for each kind of the bet chip (“$1, $5, $10” in the drawing). In addition, upon the chip return, the return time and the number of returning chips are registered with the table for each kind of chip.
Referring back to FIG. 4, when the participant in the game removes the ID card 20 from the readout unit 64, the time thereof is recognized as the game end time and registered with the table shown in FIG. 4. The accumulation/analysis server 68 refers the foregoing table managed by the PTS server 66 as shown in FIG. 6. Accordingly, the accumulation/analysis server 68 calculates the investment and the return of the participant in the game to be registered with the table in association with the user ID of the participant (refer to FIG. 4). Herein, the accumulation/analysis server 68 can acquire the kinds and the number of bet chips and the kinds and the number of returning chips for each user from the table shown in FIG. 6 by referring the game table ID, the game start time, and the game end time shown in FIG. 4, which are associated with the user ID. Thus, it is possible to calculate the investment and the return for each user and register the same in association with the user ID.
The ID card 20 is provided with a deposit checking unit 70 (refer to FIG. 1) for checking the amount of deposit of the user. In the foregoing embodiment, the chips 28 are directly bet. However, various games, in other words, the card games can be played in accordance with the checking results of the deposit checking unit 70 instead of the chips 28. In this case, the participants P1, P2, and P3 can bet arbitrary amount of money by using bet inputting means 90 (e.g., a numeric keypad) at hand. Similar to the aforementioned chips 28, all the bets are sequentially registered with the PTS server 66 and collectively managed by the accumulation/analysis server 68. The casino deposit server 72 manages the deposits in the casino collectively (refer to FIG. 1). Thus, it is possible to update the deposit balance in accordance with the points of the game results and pay an additional deposit without cash.
As described above, according to the game management system 1 in the present embodiment, it is possible to manage all the histories of the cards 26 and the chips 28 from the beginning until the end of the game. Accordingly, by referring the data registered with the PTS server 66, the accumulation/analysis server 68 can detect a fraud game and operation. Therefore, it is possible to prevent the fraud game and operation.
Specifically, each of the cards 26 and the chips 28 are constantly monitored by the first and second identification information detectors 30 and 46 respectively and registered with the tables managed by the PTS server. Thus, it is possible to find the counterfeits instantly when a counterfeit card or a counterfeit chip enters during the game. For example, when the number of cards is small, the accumulation/analysis server 68 refers the tables in FIGS. 5A to 5C to detect the deficiency in the number of cards. Accordingly, the fraud can be detected. More specifically, when poker is played as the game and four cards are registered with the table shown in FIG. 5C as the number of cards, the accumulation/analysis server 68 detects the number as the fraud of the game. When the cards are moved in such a direction that the movement is forbidden in the game, the accumulation/analysis server 68 can detect the fraud by referring the tables in FIGS. 5A to 5C. Thus, the accumulation/analysis server 68 can accurately follow the fraud operation time and the flow of the cards 26 at that time based on the histories of the cards 26 detected by the first identification information detector 30, even when the cards 26 are illegally manipulated in the conspiracy of the dealer D and the participants P1, P2, and P3.
In addition, the accumulation/analysis server 68 can detect a counterfeit chip by checking whether there is a contradiction in a relationship between the bet chips and the return. This checking is performed from the odds of the hand based on the kinds of cards at the end of the game, the kinds and the number of bet chips, and the kinds and the number of a return. For example, by preparing a table, with which a relationship between the odds and the kinds of cards is registered, in the PTS server 66, it is possible to acquire the odds of the hand from the kinds of the playing cards 26 at the end of the game registered with the table shown in FIG. 5C. When there is a contradiction between the acquired odds of the hand and the relationship between the bet chips and the return shown in FIG. 6, the contradiction can be detected as the fraud.
When detecting the fraud, the accumulation/analysis server 68 registers the fraud detection flag (“1” in the drawing indicates that the fraud is detected) with the table shown in FIG. 4 in association with the user ID. The game management system of the present embodiment can thus prevent the fraud operation since the game management system can detect the fraud operation.
According to the present embodiment, the user can utilize all the facilities with the ID card 20 (house card) given when checking in a hotel. Thus, the hotel can provide obliging services for its guests. Especially, since a game charge at a casino has been billed separately in conventional casino hotels, casino users have been irritated by the fact that the users have to manage their funds on their own. However, the ID card 20 enables the user to pay for all the bills upon check-out. As a result, burdens are reduced for the casino users.
Moreover, by utilizing the deposit function of the ID card 20, it is possible to set a limit on playing games. This eliminates extreme losses for the users, and thus the users can feel relaxed to play the games.
The principles of the present invention have been illustrated and described in the preferred embodiments, but it is apparent to a person skilled in the art that the present invention can be modified in arrangement and detail without departing from such principles. For example, poker has been an example of the game to describe the aforementioned embodiment.
