FIELD OF THE INVENTION
The present invention relates to a system and method for managing the download of gaming machine data, such as game code and other gaming machine control code.
BACKGROUND OF THE INVENTION
Today's gaming devices such as electronically controlled slot, video and similar machines generally include a central controller including a processor and a memory. The central controller controls the gaming machine, including the presentation of one or more games to a player at the gaming machine.
The processor of the gaming controller executes code to control the operation of the gaming machine. This code is stored at the memory of the gaming controller. Generally, the control code, including specific game code, is loaded into the memory when the gaming machine is manufactured.
There are a variety of circumstances which may arise when it is desirable to change the control and/or game code associated with the gaming machine controller. For example, the operator may wish to change the “paytable” so that the gaming machine returns a higher percentage of bets wagered. The operator may also wish to update an older game with a newer, more desirable one. Currently, this requires that a technician travel to the gaming machine, take the gaming machine out of service, and load new code. The new code may be loaded by replacing a static memory chip or in the case of a rewriteable memory, by overwriting older code.
There are numerous disadvantages with this arrangement, including that the arrangement takes the machine out of service and requires substantial manpower to accomplish, all reducing the profit which may be yielded by the machine. The present invention is directed at a practical manner for implementing downloads of gaming and other code, including managing the downloads without interruption to the gaming machine.
SUMMARY OF THE INVENTION

This data may include information such as the length of time of game play, amounts bet, amounts awarded, and a wide variety of other information. In general, the player tracking device of each gaming machine 20 is adapted to transmit the player tracking data over the communications link(s) to the player tracking host 54. Based on player activities, a player may be awarded a “comp”. Comps are generally awards, such as prizes, money, free game play, lodging or the like which are provided to the player apart from any awards which the player receives from direct game play. Such are referred to as “comps” as they are “complimentary” and generally do not require specific obligation, such as an additional bet, in order to be received. The system is often referred to as a reward or loyalty system because a player is generally awarded an award resulting from an extended or frequent game play. In one arrangement, a player may acquire points based upon a game criteria, such as amounts bet, won or lost. If a player accrues sufficient credits, the player is awarded a reward.
As illustrated in FIG. 2, a communication interface 72 is provided between the SMIB 70 and the player tracking system network 58. The communication interface 72 may comprise a wide variety of devices. For example, the communication interface 72 may comprise a modem or a PC type card including an antennae for implementing a wireless communication protocol such as Bluetooth. The communication interface 72 may comprise a PC type card facilitating a protocol over a wired network, such as Ethernet or Firewire®.
Player tracking information is transmitted via the SMIB 70 to the player tracking host 54. In one embodiment, data is transmitted from the SMIB 70 to the network 58 via the communication interface 72. This data is routed to the player tracking host 54.
In one embodiment, the information which is transmitted may comprise game play information regarding a player's game play activity. This information may include coins (or other monetary amounts credited), coins paid out, and time of play.
In a preferred embodiment, a communication link is also provided between a gaming code host 56 and the SMIB 70. In one embodiment, the gaming code host 56 is associated with the player tracking system network 58 and the communication link is provided by the network 58.
The gaming code host 56 may comprise a variety of devices. In one embodiment, the gaming code host 56 comprises a computing device configured as a server. In such a configuration, the gaming code host 56 may include at least one processor, at least one memory device, and at least one communication interface. The memory device may comprise a mass storage device for storing large amounts of data, such as an array of hard discs.
In one embodiment, the gaming code host 56 may comprise a portion of or be integrated with the player tracking host 54. In other words, a single computing device or group of computing devices may be configured to perform player tracking functions as detailed above and gaming code storage and dissemination, as detailed below.
Preferably, the game code host 56 stores executable code or other data or information for use by the gaming machine controller 60. This code may comprise, for example, game code or other control code for use by the gaming machine controller, such as for use in controlling the various peripheral devices of the gaming machine 20. The code may be stored in a variety of forms. For example, the code may be encrypted, compressed, and comprise compiled or uncompiled data.
In accordance with a method of the invention, as described in more detail below, code may be transmitted from the game code host 56 to the gaming machine 20 for use by the gaming machine controller 60 of the gaming machine 20 in operating the gaming machine, including presenting one or more games. In a preferred embodiment, code is transmitted from the game code host 56 to the SMIB 70 of the gaming machine 20, and then some or all of the code in modified or unmodified form is provided by the SMIB 70 to the gaming machine controller 60.
As illustrated in FIG. 2, in a preferred embodiment, a communication link 74 is provided between the gaming machine controller 60 and the SMIB 70. The communication link 74 permits data to be transmitted from the SMIB 70 to the gaming machine controller 60, and from the gaming machine controller 60 to the SMIB 70.
In a preferred embodiment, the communication link 74 operates by a proprietary protocol which permits only limited interaction between the SMIB 70 and gaming machine controller 60. This proprietary protocol is preferably different than the communication protocol by which the SMIB 70 transmits information to and receives information from the network 58, including the player tracking host 54 and game code host 56. In this manner, attempts to tamper with the gaming machine controller 60 via access through the network 58 and SMIB 70 are prevented. This ensures the security of the gaming machine controller 60.
In accordance with one embodiment of the invention there is a method of managing or controlling the download of code or other information from a remote location to a gaming machine. In one embodiment, the method is implemented via a gaming system including a game code server 56, network 58, and at least one gaming machine 20 as described above.
In one embodiment of method, in a first step St, gaming machine code is provided to a device remote from the gaming machine. As described above, this remote device may comprise a game code server 56. The gaming machine code may be provided to the game code server 56 or other device in a variety of manners. For example, the code may be generated at the game code server 56. The code may also be generated remotely and be transferred to the server, such as through a network communication link or a removable media such as CD-ROM, removable disk or the like.
As indicated above, the code may be in a variety of forms and may be configured for a variety of purposes. For example, the code may be in a variety of languages. The code may also be configured for use by a gaming controller in presenting a game or specifically controlling a particular peripheral device of the gaming machine. As indicated, the code is preferably machine readable code. The code may comprise data or other information, as is known in the use of computing devices.
In a second step S2 of the method, the code is transferred from the remote device, such as the game code server 56, to a portion of the gaming machine 20 other than the gaming machine controller 60. As indicated above, this other portion of the gaming machine 20 preferably comprises a secondary device. By “secondary device,” it is meant a device other than the device which is primarily intended to run or utilize the code or information. In one preferred embodiment, this secondary device comprises the player tracking controller or SMIB 70.
In one embodiment, the code may be transferred to the SMIB 70 or other device based on a variety of criteria or events. For example, in one embodiment, the trigger for the download may be effected at the game code server 56. As one example, a game operator may wish to update particular code associated with one or more gaming machines 20, such as bill validation code. The operator may cause new code to be transmitted from the game code server 56 to each gaming machine 20. For example, the operator may input a request to transmit code directly to the game code server 56 by a keyboard or other direct input device.
In another embodiment, a request for code may be transmitted from the gaming machine 20 to the game code server 56 for fulfillment. In one embodiment, the gaming machine controller 60 may generate such a request. For example, the gaming machine controller 60 may cause the display 68 to display a list of games which may be played at the gaming machine 20. A player may select a particular game from the list. In response to the selection, the gaming machine controller 60 may transmit a request to receive the gaming code necessary to present the selected game to the player. In a preferred embodiment, the request from the gaming machine controller 60 is transmitted to the SMIB 70 via the communication link 74, and then from the SMIB 70 to the game code server 56.
In another embodiment, the request may be generated by and transmitted from the SMIB 70. For example, a player may be permitted to select their favorite or “default” game. The default game is presented to the player at the gaming machine 20 whenever the player identifies themselves at the gaming machine 20. For example, a player may insert their player tracking card into the card reader 32. The player tracking card may include information regarding the player's preferred game. Alternatively, the player tracking card may include player identification information which the player tracking controller sends to the player tracking host 54. The player tracking host 54 may utilize the identification information to identify the player's preferred game. This information may be sent back to the SMIB 70 and then the SMIB 70 may transmit a request to the game code server 56 for game code for the player's game. Alternatively, the game information may be transmitted from the player tracking host 54 to the game code server 56 directly.
The game code may be transmitted to the SMIB 70 or other device of the gaming machine 20 in a variety of manners. In part, the manner by which the code is transmitted is dependent upon the communication protocol used. Generally, however, the code will be transmitted in packetized form. Preferably, each data packet includes a destination address, such as in an address header. The packetized form of the transmission permits the code to be transmitted to a variety of different gaming machines 20 associated with the system 50 at generally the same time. Individual packets are reassembled at each gaming machine 20.
The code may be transmitted in whole or in part during a transmission event. For example, if a request is made for particular game code, the game code may be transmitted in portions or segments spaced over time, or be transmitted immediately. The manner by which code is transmitted may be determined by a variety of criteria. In one embodiment of the invention, the request for code may include an indication of the priority of the need for the code. For example, in the case of an upgrade of code, the code may be transmitted when sufficient bandwidth is detected as being available to permit the transmission without slowing current network activity, such as the transmission of player tracking data. In the case where a player is requesting to play a particular game, the request may be of a high priority. In this event, the code may be transmitted immediately, even though such may slow the speed at which other data is transmitted between the various gaming machines 20 and the other devices on the network 58.
In a step S3 of the method, the code is processed by the SMIB 70 or processing device of the secondary device, such as a processor of a player tracking controller. The processing may simply comprise a re-transmission of the code or data to the gaming machine controller 60. In other embodiments, the processing may comprise the compilation of code, assembly of data or the like. For example, in one embodiment where code is transmitted in portions over an extended period of time, the processing may comprise assembling the various portions of the code.
In a preferred embodiment, the code is received by the communications interface 72 and is routed to a memory of the SMIB 70. In one embodiment the code is stored at the memory of the SMIB 70 over a period of time, and in another embodiment the code is only stored until it has been processed and transmitted to the gaming machine controller 60. In one embodiment, the code may be stored until overwritten.
In a step S4 of a method, the processed code is provided to the gaming machine controller 60. In one embodiment this step comprises the transmission of the code over the communication link 74 from the SMIB 70 to the gaming machine controller 60.
In a preferred embodiment, the transmitted code is stored at the memory 64 of the gaming machine controller 60. The code may be stored in other locations.
Once the code is transmitted to the gaming machine controller 60, the code may be further processed. In a preferred embodiment the code is used, such as executed by the CPU 62, by the gaming machine controller 60.
The apparatus or system for implementing the methods of the invention may vary. As indicated, in one embodiment, the game code or other data is transmitted from the game code host 56 to the gaming machine 20 via the player tracking network 58. In embodiment, the game code host 56 in on or a part of this network. In another embodiment, the game code host 56 is associated with a different network, and the game code is transmitted from the game code host 56 via this network and the player tracking network 58 to reach the gaming machine 20.
In another embodiment, the game code host 56 may be arranged to transmit game code to the player tracking controller via a network or communication link entirely separate from the network 58 connecting the player tracking controller and the player tracking host 54. In this manner, a secure network link may be provided to the gaming machine over which gaming code is transmitted. For example, in one embodiment, the player tracking device of the gaming machine 20 may include a first communication interface 72 and a second communication interface (not shown). The first communication interface 72 connects the player tracking device to the network 58 (and thus the player tracking host 54), such as via a wired or wireless link. The second communication interface connects the player tracking device to the game code host 56, such as via a wired or wireless link. In a preferred embodiment, the player tracking device is connected by a wired link to a wired network 58, and via a wireless link to the game code host 56 (or via a wireless link to a part of a network with which the game code host 56 is associated). In this configuration, a gaming machine 20 which is already wired to an existing wired player tracking network can be simply configured to implement the invention without the need to put into place another wired link, but still provide greater data bandwidth and a dedicated path, by utilizing a wireless link. In another embodiment, the player tracking device includes a single communication interface adapted to communicate with both communication links/networks.
Game code may be transmitted to a secondary device of the gaming machine other than the player tracking controller. For example, a processing unit/controller/communication interface element may be associated with the machine and have as its sole or primary purpose only serving as the interface for the download of control code to the gaming machine.
As indicated, in one embodiment the player tracking host 54 and game code host 56 are located remote from the gaming machine 20. By “remote,” it is generally meant that these devices are not located within or at the gaming machine 20. Further, one or more gaming machines 20 which are located remote from one another may be associated with the same game code host 56. The one or more gaming machines 20 may be associated with different gaming properties or operators, or a variety of properties or locations operated by a single entity or different entities. In such an embodiment, the one or more communication links forming the network 58 may comprise phone lines or the link connecting the properties.
The system and method in accordance with the present invention has numerous advantages. As one aspect of the invention, a means is provided for providing gaming code or other data from a remote location to a gaming machine. This means provides the code to the gaming machine for use by the gaming machine controller in an indirect fashion.
A number of advantages are realized as a result of the indirect download of code to the gaming machine. One advantage is that resources of the gaming machine controller are not utilized to effect the download. As one example, a gaming machine controller may be storing and executing a particular set of gaming code at a time when the operator wishes to update the code for that game. In the arrangement of the invention, the updated code can be transmitted to the machine and be stored at the machine without interrupting the gaming machine controller. When play of the gaming machine ceases, then the code may be provided to the gaming machine controller for installation and use.
In a preferred embodiment, the player tracking controller or other secondary device to the gaming machine controller acts as the “queue” for downloaded code. Thus, while the gaming machine controller may be running a particular game, the code can be downloaded to the player tracking controller or other secondary device. It will be appreciated that the time necessary to download code from a remote device to the player tracking controller or other secondary device will generally be substantially greater, and generally greater in magnitudes, than the time needed to transmit the code from the player tracking controller or other secondary device to the gaming machine controller.
As one aspect of the invention, the “queuing” effect of the download has the advantage of improving network traffic. In many cases, particular code need not be immediately accessible to the gaming machine controller of a gaming machine. However, by necessity, without the queuing feature of the invention, the code must generally be sent as quickly as possible to avoid the gaming controller from being tied up in waiting for the code for installation. In accordance with the invention, during periods of high network traffic, only limited amounts of code may be downloaded to the player tracking controller or other secondary device of the gaming machine. During lower periods of network traffic the code may be downloaded at higher rates. Regardless of the speed of download, however, the player tracking controller is arranged to obtain and store, including assembling this code. When the entirety of the code is downloaded, the code can be immediately provided to the gaming machine controller.
As another aspect of the invention, a request for code or to provide code may include priority information. This priority information can be used to match the need for code at a particular time or speed with the available network bandwidth. Thus, only code immediately required is immediately transmitted, while other code may be transmitted only when the network bandwidth is greater, as discussed above.
In accordance with the invention, greater amounts of code are immediately available to the gaming machine controller. For example, the gaming machine controller may have game code for a first game loaded into its memory. The player tracking controller or other secondary device may store game code for a second game. In the event a desire exists to present the second game, the code is already available to the gaming machine controller on an immediate basis. As one aspect of this feature, this allows the gaming machine controller to have less memory. This may allow, for example, the gaming machine controller to include only higher speed access memory, such as RAM, instead of a hard drive, since less code needs to be stored by the gaming machine controller. This is because the gaming machine controller still has ready access to other code necessary to present other games or to control the gaming machine via the player tracking controller or other secondary device memory.
Yet another advantage of the invention is that in some instances, older gaming machines may not be provided with a network link to their gaming machine controllers. These gaming machines may have been retrofitted with a separate player tracking device associated with a player tracking network or system. In accordance with the invention, gaming code can now be provided to the gaming machine controller using the existing player tracking network, avoiding the need for another network or communications link.
It will be understood that the above described arrangements of apparatus and the method therefrom are merely illustrative of applications of the principles of this invention and many other embodiments and modifications may be made without departing from the spirit and scope of the invention as defined in the claims.
