FIELD OF THE INVENTION
The present invention relates generally to gaming machines that support wagering on wagering games, and more particularly to controlling schedules and programs executed on reconfigurable gaming machines.
BACKGROUND OF THE INVENTION
Gaming machines, such as slot machines and video poker machines, have been a cornerstone of the gaming industry for several years. Different players, changing popularity of types of games, geographic location of a gaming machine on a casino floor, range of amounts that can be wagered, time of day and day of the week may cause players to be attracted to different types of gaming machines. Casino operators consequently monitor the amount of play of different types and wagering limits of gaming machines and manage the availability of different games to maximize profitability to the operator. Therefore, there is a continuing need for gaming machine manufacturers to provide the operator with increased control of reconfigurable gaming machines.
A centralized gaming controller may have responsibility for reconfiguring remote gaming machines to provide different games and/or variations of games such as the range of the amounts that can be wagered. Such a system permits the operator to change a gaming machine (remote terminal) from one game to another and to vary characteristics of a game. This gives the operator an opportunity to advantageously schedule games and game characteristics being offered to the players to maximize profits. However, a malfunction of the controlling server or communication link between the server and the gaming machines could result in the gaming machines remaining in an undesired mode of operation for longer than anticipated where the server is responsible for implementing changes in gaming machine operation. This could result in lower profits to the operator, e.g. being unable to change a low minimum wager limit used during a weekday to a higher minimum wager limit during a peak interval such as a Saturday evening.
SUMMARY OF THE INVENTION
According to one aspect of the present invention, a gaming machine includes an input/output module associated with a microprocessing unit. The module is adapted to download from a server time-based schedules of gaming actions to be taken by the gaming machine. Memory in the gaming machine stores the time-based schedules. The memory also stores a time-based backup schedule of gaming actions to be taken. A microprocessing unit determines whether one of the time-based schedules or the backup schedule will be implemented. The microprocessing unit controls the performance of the gaming actions defined by the schedule being implemented.
According to another aspect of the invention, a method is implemented for controlling gaming machines that permits wagering on games. The method includes downloading from a server time-based schedules, including a first schedule, of gaming actions to be taken by a first gaming machine. The time-based schedules are stored in memory in the first gaming machine. Also stored in the memory is a time-based backup schedule of gaming actions to be taken by the first gaming machine. A determination is made by the first gaming machine of whether the first schedule or the backup schedule is to be implemented. The first gaming machine implements the gaming actions defined by the selected schedule.
According to yet another aspect of the invention, a computer readable storage medium is encoded with instructions for directing a gaming machine to perform the above method.
Additional aspects of the invention will be apparent to those of ordinary skill in the art in view of the detailed description of various embodiments, which is made with reference to the drawings, a brief description of which is provided below.

DETAILED DESCRIPTION
Various embodiments of this invention can be utilized. The drawings and descriptions of embodiments of the invention exemplify its principles and are not intended to limit the broad aspect of the invention to only the illustrated embodiments.
Referring to FIG. 1, an exemplary gaming system 10 includes a gaming distributor 12 coupled to a central gaming business 14 by communication links 16. Local gaming facilities 18 are connected by communication links 20 to the central gaming business 14. As used herein, “gaming” refers to the use of various games that support the placing of wagers on the outcome of the games, e.g. a video poker machine. The gaming distributor 12 may consist of the creator or distributor of games and/or gaming machines, e.g. WMS Industries Inc. The central gaming business 14 may consist of centralized operations for a casino or licensed gaming machine operator. The local gaming facilities 18 may consist of geographically separated locations, i.e. different casinos, all owned or controlled by the same central gaming business.
The gaming distributor 12 may include a computer workstation 22 coupled to a nonvolatile memory storage device 24 such as a hard drive. The workstation 22 is also coupled to a server 26 that provides a host for communications over communication channels 28. The workstation 22 may provide a plurality of functions that serve to support the gaming distributor. In accordance with this illustrative embodiment, one function of the workstation 22 is to provide support for the central gaming business 14. For example, the workstation 22 may cause an updated version of a software implemented game stored in device 24 to be downloaded by server 26 to the central gaming business 14 for storage and redistribution to the associated gaming machines at its local gaming facilities.
A central gaming business 14 includes a workstation 30 supported by data storage element 32 and a server 34 that serves as a communication host with the gaming distributor 12 and communication channels 36 coupled to the local gaming facilities 18. The server 34 also supports communication with a router 38 that in turn supports wireless communications with the wireless device 40 which may comprise a laptop computer, personal digital assistant, a data enabled cellular telephone, etc. The wireless device 40 permits users, e.g. administrators and operational personnel of the central gaming business, to receive information generated by workstation 30 as well as information concerning the local gaming facilities 18. It may be utilized to provide data input and instructions to workstation 30.
Each local gaming site 18 includes a server 42 that functions as a host of communications between the subject local gaming facility and the central gaming business 14 and the other local gaming facilities. A router 44 routes communications between the server 42 and other elements including data storage element 46, gaming machines 48 and a wireless communication link with a wireless device 50. The data storage element 46 can be utilized to store control information, gaming machine statistics and gaming programs and/or updates to gaming programs. For example, assume that gaming machines 48 at the subject local gaming facility are to be updated with a new version of a game. This new version may have been downloaded from the gaming distributor 12 by the central gaming business 14 and stored in data storage element 32. At an appropriate time under the control workstation 30, the new version is downloaded and stored by the data storage element 46 of each local gaming facility that contains a gaming machine 48 to receive the new version. At a convenient time such as determined by server 42, the new version stored in data element 46 will be downloaded into the memory of the appropriate gaming machines 48.
Alternatively, a new version of the game can be downloaded directly from the central gaming business 14 to the respective gaming machines 48. The wireless device 50 is similar to the previously described wireless device 40 and preferably supports bidirectional communications. However, in one exemplary embodiment, wireless device 50 is primarily utilized to display status information to gaming system managers concerning the status and utilization of the gaming machines 48 so that the managers are free to roam around the gaming facility. It will be noted that not all of the gaming machines at a particular local gaming facility may be capable of being remotely updated. Those skilled in the art will appreciate that new gaming machines may be designed with sufficient processing and communications ability to be able to be remotely updated and controlled without requiring intermediate processing such as provided by server 42 and router 44. Of course, a gaming system manager may utilize a personal computer 52 connected to server 42, or alternatively to router 44, to display gaming information and provide control instructions for the gaming machines 48 located at the same local gaming facility.
FIG. 2 shows workstation 30 in more detail. It includes a microprocessor 60 that is supported by read-only memory (ROM) 62, random access memory (RAM) 64 and nonvolatile data storage element 66 such as a hard disk. As will be appreciated by those skilled in the art, ROM 62 stores boot-up control instructions and information for microprocessor 60, and RAM 64 normally stores application control instructions and data obtained from data storage element 66 and/or ROM 62 associated with the implementation and running of an application program. Input devices 68 such as a keyboard and/or mouse and an output device 70 such as a monitor are typically coupled by corresponding support modules (not shown) to microprocessor 60 enabling a user to provide inputs and observe displayed information. An input/output (I/O) module 72 is coupled to microprocessor 60 and enables bidirectional communications between the microprocessor and external devices thereby allowing the module to transmit instructions to and receive requests from the various gaming machines. The microprocessor and required supporting elements forms a microprocessing unit.
Workstation 30, operating under the control of application software, supports a variety of gaming programs and related characteristics as well as the scheduling thereof for use on the remotely reconfigurable gaming machines. This provides a game system manager with increased flexibility and convenience in being able to control and modify the operation of gaming machines.
FIG. 3 shows an illustrative gaming machine 48 in more detail. It includes a microprocessor 80 that is supported by ROM 82, RAM 84 and nonvolatile data storage element 86 such as a hard disk. As will be appreciated by those skilled in the art, ROM 82 stores boot-up control instructions and information for microprocessor 80, and RAM 84 normally stores application control instructions and data obtained from data storage element 86 and/or ROM 82 associated with the implementation and running of an application program. Input devices 88 such as buttons, keypad, joystick, etc. and an output devices 90 such as video on a display, lights, audio, sounds, etc. are typically coupled by corresponding support modules (not shown) to microprocessor 80 enabling a user of the gaming machine to provide inputs to the game being played and receive output information about the game. A manual override switch disposed inside the gaming machine for operation by an administrator is another input device. Its function as described in greater detail with regard to FIG. 5. An input/output (I/O) module 92 is coupled to microprocessor 80 and enables bidirectional communications between the microprocessor and external devices, e.g. allowing the module to receive instructions from and transmit requests to the server 42 via router 44. An administration port 94 may interface with a wire or optical cable employing a known protocol, e.g. serial, parallel, or USB, or may consist of a wireless communication module employing a known wireless protocol. The administration port permits an authorized administrator to transmit information including control instructions and game application programs directly to the gaming machine and to receive information including statistics, data, etc. from the gaming machine such as by coupling a computing device, e.g. laptop computer, to the gaming machine via the administration port 94. Alternatively, local software on the gaming machine could support changes to gaming actions while in an administration mode such as by touch screen input. This permits local as well as remote configuration of the gaming machine and provides a system manager with increased flexibility and convenience in being able to locally control and modify gaming action on the gaming machines. “Gaming action” refers to which game is being executed as well as controllable parameters associated with a game, including but not limited to, wagering limit, denomination, available pay tables, game themes, etc. Configuring a game machine by the administration port can be used as a backup updating/control method of the gaming machines where the primary updating/control method is from a server in a client/server model. Or it can be used as the primary method without the use of a server. The microprocessor and required supporting elements forms a microprocessing unit. Various types of hard wired circuitry can be used in the gaming machine for portions that do not require changes in logic.
FIG. 4 shows an illustrative functional diagram of a gaming machine 100. The gaming machine illustrated in FIG. 4 is controlled by a microprocessing unit such as described in FIG. 3 that operates under stored program instructions. An operating system 102 that preferably includes a calendar function 104 and clock function 106 controls the interaction and functionality of operation among modules of the microprocessing unit. Utility applications 108 provide additional functionality and capabilities for the gaming machine such as passing information among applications and bidirectional communications with external devices, e.g. a server or router.
A scheduling application 110 monitors date and time, and contains one or more schedules that control the game and its characteristics to be run on the gaming machine 100. A “schedule” refers to predetermined games and associated game functions that change at defined times, days, or dates. This accommodates changes per day of week, holidays, and special events associated with the casino such as superbowl party, concert, boxing match, etc. Each of the schedules contained in the scheduling application includes game data 112 that determines controllable characteristics of the associated game, e.g. minimum/maximum wagering limit. In accordance with one embodiment of the present invention, the scheduling application 110 includes a first schedule of games to be run on the gaming machine where the first schedule and the games controlled by the first schedule are downloaded from a central server. Additionally, a backup schedule and corresponding games to be run on the gaming machine are also stored in memory of the gaming machine. The utilization of the backup schedule is explained below with regard to FIG. 5.
Game programs 114, 116, 118 and 120 are stored in memory of the gaming machine 100 for use in accordance with one or more schedules stored as part of the scheduling application 110. Each of the game programs may represent a different wagering game suitable for play on the physical gaming machine.
FIG. 5 shows an illustrative method for updating and controlling a gaming machine in accordance with present invention. In step 150 a determination is made of whether a manual override of a schedule downloaded from the server is in effect. An internal switch in the gaming machine may be manually controlled by an administrator to provide an override signal. Alternatively an override signal may be communicated to the gaming machine such as from local software or remote software coupled via the administration port 94. A NO determination in step 150 results in a determination in step 151 of whether the current schedule from the server is still within a valid time frame, i.e. is a time/day/date parameter downloaded with the schedule from the server still within the current time/day/date? A NO determination by step 151 results in the backup gaming schedule being run as indicated at step 164. A YES determination by step 151 results in a determination in step 152 of whether communications are available with the server, i.e. can the server and the subject gaming machine communicate with each other? A YES determination by step 152 results in a further determination in step 154 of whether an update to the gaming machine is to be made from the server. A YES determination in step 154 results in new information being loaded from the server in step 156. Such server information may include a new gaming schedule, data associated with an existing game on the gaming machine that will change the characteristics of the existing game, control instructions, or downloading a new game and/or deleting an existing game. Following step 156 or upon a NO determination by step 154, the gaming machine proceeds to implement the current server-based schedule as indicated at step 158. The delay indicated in step 160 represents a selectable time interval to delay before returning for another pass through the loop as described in FIG. 5. Depending upon the configuration of the gaming machine environment a typical delay interval could consist of less than 10 seconds or could be several minutes or hours.
A NO determination at step 152, indicating that communications are not available with the server, results in a determination in step 162 of whether the loaded game schedule from the server differs from a backup schedule held in memory in the game machine. A NO determination in step 162 indicating that the game schedule from the server does not differ from the backup schedule results in the gaming machine continuing to run the current schedule from the server at step 158. A YES determination by step 162 results in the gaming machine running the backup gaming schedule as indicated at step 164 with the process continuing to delay step 160. Alternatively, upon a NO determination by step 152 indicating that communications are not available with server, step 162 could be omitted with the backup gaming schedule of step 164 being implemented.
A YES determination by step 150 indicates that a manual override of the server's schedule has been made and results in gaming machine executing the backup gaming schedule at step 164. The intent of the manual override is to cause control of the gaming schedule being run by the gaming machine to be controlled by a backup schedule as opposed to the last schedule downloaded from the server. Upon a loss of communications with the server and a determination that the backup schedule is not the same as the last schedule downloaded from the server, the backup schedule will be automatically implemented by the gaming machine. Maintaining a backup schedule on the gaming machine allows it to operate in a desired mode in the event of a malfunction of the server or its communication link with the gaming machine.
The backup schedule can be manually loaded into the gaming machine through administration port 94. Alternatively, the backup schedule can be downloaded from the server for later use by the gaming machine should communications be lost with the server. Of course the backup schedule itself can be updated as needed.
The gaming machine 48 in one example employs one or more computer-readable signal-bearing media. The computer-readable signal-bearing media store software, firmware and/or assembly language for performing one or more portions of one or more embodiments of the invention. Examples of a computer-readable signal-bearing medium for the gaming machine 48 comprise ROM 82, RAM 84 and hard drive 86. The computer-readable signal-bearing medium for the gaming machine 48 in one example comprise one or more of a magnetic, electrical, optical, biological, and atomic data storage medium. For example, the computer-readable signal-bearing medium comprise floppy disks, magnetic tapes, CD-ROMs, DVD-ROMs, hard disk drives, and electronic memory. In another example, the computer-readable signal-bearing medium comprises a signal transmitted over a network coupled with the gaming machine 48; see FIG. 1.
The steps or operations described herein are just exemplary. There may be many variations to these steps or operations without departing from the spirit of the invention. For instance, the steps may be performed in a differing order, or steps may be added, deleted, or modified.
