1. Technical Field
This description generally relates to the field of gaming devices, and more particularly to enabling participation in multiple progressive jackpots at a single gaming device.
2. Description of the Related Art
Gaming properties often devote a large percentage of floor space to gaming devices. Each gaming device presents players with individual games of chance, games of skill, or combinations thereof that a player may wager on.
Many gaming properties also offer progressive jackpots tied to one or more of the gaming devices. As used herein, the term “progressive jackpot” is a general term referring to any jackpot wherein the value of the jackpot increases as a fraction of at least some wagers accepted at participating gaming devices. Gaming properties may offer individual progressive jackpots associated solely with a single gaming device or group progressive jackpots associated with a plurality of gaming devices. Since the value of a progressive jackpot increases as a fraction of wagers made, the progressive jackpots can reach sizeable amounts that may help to increase players' excitement when playing the gaming devices.
It would be desirable to make play of these gaming devices and participation in progressive jackpots even more enjoyable for the players.
In one embodiment, a computer-implemented method of enabling participation in progressive jackpots in a gaming property comprises: accepting a wager at a gaming device; logically associating the wager with a first progressive jackpot, the first progressive jackpot associated with a first set of participating gaming devices; and logically associating the wager with a second progressive jackpot different than the first progressive jackpot, the second progressive jackpot associated with a second set of participating gaming devices, the second set of participating gaming devices comprising more gaming devices than the first set of participating gaming devices.
In another embodiment, a gaming device is disclosed, the gaming device comprising: a housing; a display carried by the housing; a user interface carried by the housing and configured to receive user input from a player; a processor that executes instructions; and a computer-readable memory that stores instructions. The instructions stored on the computer-readable memory may cause the processor to enable participation in progressive jackpots, by: accepting a wager via the user interface; logically associating the wager with a first progressive jackpot, the first progressive jackpot associated with a first set of participating gaming devices; and logically associating the wager with a second progressive jackpot different than the first progressive jackpot, the second progressive jackpot associated with a second set of participating gaming devices, the second set of participating gaming devices comprising more gaming devices than the first set of participating gaming devices.
In yet another embodiment, a computer-readable medium stores instructions that cause a processor to enable participation in progressive jackpots, by: receiving information indicative of a wager made at a gaming device; logically associating the wager with a first progressive jackpot, the first progressive jackpot associated with a first set of participating gaming devices; and logically associating the wager with a second progressive jackpot different than the first progressive jackpot, the second progressive jackpot associated with a second set of participating gaming devices, the second set of participating gaming devices comprising more gaming devices than the first set of participating gaming devices.

Description of an Exemplary Gaming Property
The gaming property 100 may comprise any of a variety of establishments housing a plurality of gaming devices 104 used for gaming/gambling. In one embodiment, the gaming property 100 may be a casino. However, even convenience stores or gas stations having one or more gaming devices may be a gaming property 100.
In one embodiment, the banks 108 may comprise a plurality of gaming devices 104 grouped in accordance with a floor layout of the gaming property 100. For example, the gaming devices 104a-c may form a row of similar gaming devices in the gaming property 100. However, in other embodiments, the banks 108 may be defined as any of a number of logical groupings of the gaming devices 104 within the gaming property 100.
As illustrated, a network may be formed within the gaming property 100 between the progressive jackpot controllers 102, 106a, 106b and the gaming devices 104. This network may comprise any of a variety of networks and related hardware and/or software. In some embodiments, the network may comprise a wired or wireless enterprise-wide computer network, intranet, extranet or the Internet.
The gaming devices 104 may comprise any of a variety of electronic devices offering games of chance, games of skill, or combinations thereof that a player may wager on. Such games may include mechanical slots, video slots, video keno, video poker, video blackjack, Class II bingo, lottery, craps, a mechanical or video representation of a wheel game, etc. The gaming devices 104 may have a variety of configurations, but one example structure and configuration for the gaming devices 104 is discussed in greater detail with respect to
Of course, it may be understood that each gaming device 104 need not enable play of the same game or games as every other gaming device 104. For example, some of the gaming devices 104 may enable play of video slots, while others of the gaming devices 104 may enable play of video blackjack.
As illustrated in
Of course, other logical sets of gaming devices associated with corresponding progressive jackpots may also be defined within the gaming property 100. The sets may be organized in accordance with any of a variety of characteristics. For example, the sets may be based on physical location, types of gaming devices 104, characteristics of players playing the gaming devices 104, etc. In one embodiment, the gaming devices 104 in two or more banks 108 may define a set that comprises a subset of the total number of gaming devices in the gaming property 100.
Still other sets of participating gaming devices may be defined to include gaming devices not located within the illustrated gaming property 100. For example, gaming devices may be logically organized to form county-wide or state-wide sets of gaming devices associated with corresponding progressive jackpots. Such gaming devices may be housed in a plurality of gaming properties located throughout a respective geographical area.
Based on the above-defined sets, each gaming device 104 may participate in a plurality of progressive jackpots, wherein a single wager placed at a gaming device 104 may be logically associated with at least a first progressive jackpot and a second progressive jackpot different than the first progressive jackpot. The first progressive jackpot may be associated with a first set of participating gaming devices, and the second progressive jackpot may be associated with a second set of participating gaming devices comprising more gaming devices than the first set of participating gaming devices. As one example, the gaming device 104a may be a member of a unitary set, a bank-wide set identified as the bank 108a, and a property-wide set defined by the gaming property 100. The gaming device 104a may therefore enable participation in an individual progressive jackpot, a bank-wide progressive jackpot and a property-wide progressive jackpot. Indeed, a single wager placed at the gaming device 104a may be logically associated with all three of these jackpots.
Of course, not all of the gaming devices defining a particular set need participate in the corresponding progressive jackpot concurrently. Rather, a set is defined by the gaming devices that are configured to contribute to and participate in a corresponding progressive jackpot, regardless of the current state of those gaming devices.
In one embodiment, once a wager has been logically associated with the first and the second progressive jackpots, a first fraction of the wager may be allocated to increase the first progressive jackpot, and a second fraction of the wager may be allocated to increase the second progressive jackpot. For example, a first fraction of a wager made at the gaming device 104a may be allocated to increase the bank-wide progressive jackpot, and a second fraction of the wager may be allocated to increase the property-wide progressive jackpot. In some embodiments, the gaming devices 104 may allocate a fraction of only particular wagers to the progressive jackpots (e.g., only those wagers made while playing particular games, or only those wagers in which a maximum number of bets has been placed).
Since the progressive jackpots may be completely independent, different fractions may be allocated to increase the different progressive jackpots. In one embodiment, a greater fraction may be allocated to those jackpots with fewer participating gaming devices. For example, the bank-wide progressive jackpot may be allocated a greater fraction of wagers than the property-wide progressive jackpot, while the individual progressive jackpot may be allocated a still greater fraction.
It may be understood that such allocations are independent of any particular accounting method used to increase progressive jackpots by the appropriate amount. In one embodiment, the value of a progressive jackpot may simply be incremented electronically, while the monies represented by the wagers collected are placed in one or more accounts held by the gaming property 100.
In one embodiment, a player playing one of the gaming devices 104 may win at least a portion of one of the first and the second progressive jackpots when making a single wager, with independent odds of winning each progressive jackpot. In one embodiment, only one of the first and the second progressive jackpots may be won with any single wager. However, in other embodiments, two or more progressive jackpots may be won with the same wager.
The progressive jackpots may be won when a particular outcome results from a game offered at the gaming device 104. For example, certain outcomes of a video slot game may indicate a win of at least a portion of an appropriate progressive jackpot. In one embodiment, a more likely outcome may indicate a win of at least a portion of the first progressive jackpot, while a less likely outcome may indicate a win of at least a portion of the second progressive jackpot.
The odds of winning each progressive jackpot may be fixed or variable. In one embodiment, the odds of winning progressive jackpots associated with more gaming devices 104 may be worse than the odds of winning progressive jackpots associated with relatively fewer gaming devices.
Eligibility to win all or a portion of a progressive jackpot may also be based on one or more factors. In one embodiment, a player must place a wager equal to or greater than a certain minimum number of bets in order to be eligible to win one or more of the progressive jackpots. In another embodiment, a player may be eligible to win more or less of a progressive jackpot depending upon the number of bets wagered. In yet another embodiment, a player must have a player account established at the gaming property 100 in order to be eligible.
Each progressive jackpot may be monitored and administered at one of the computing devices within the gaming property 100. In some embodiments, the progressive jackpots may be monitored and administered at different progressive jackpot controllers. In other embodiments, at least some of the progressive jackpots may be monitored and administered at one universal progressive jackpot controller.
In one embodiment, the individual progressive jackpots may be monitored and administered at the gaming devices 104 themselves. For example, a progressive jackpot program executed on each of the gaming devices 104 may be configured to monitor and administer a corresponding individual progressive jackpot. The progressive jackpot program may maintain, inter alia, information indicative of which fraction of wagers should be allocated to the individual progressive jackpot, rules associated with the individual progressive jackpot, and a current value of the individual progressive jackpot. The progressive jackpot program may also maintain other information associated with the wagers made at the gaming devices 104. For example, in one embodiment, the progressive jackpot program may store information indicative of the sizes of the wagers, the times at which the wagers were placed, player identifiers associated with the wagers, etc.
The property-wide progressive jackpot controller 102 may, inter alia, monitor and administer the property-wide progressive jackpot. In some embodiments, more than one progressive jackpot may be hosted on the property-wide progressive jackpot controller 102 (including, e.g., individual or bank-wide progressive jackpots). As illustrated, the property-wide progressive jackpot controller 102 may comprise a computing device communicatively coupled to the gaming devices 104 participating in the property-wide progressive jackpot. In one embodiment, the property-wide progressive jackpot controller 102 may perform many of the same tasks described above with reference to the progressive jackpot program of each gaming device 104. The property-wide progressive jackpot controller 102 may be implemented in any of a variety of types of hardware. One example progressive jackpot controller is described in greater detail below with reference to
When a wager is made at a gaming device 104 that is associated with the property-wide progressive jackpot, information indicative of that wager may be forwarded to the property-wide progressive jackpot controller 102. The forwarded information may include, inter alia, information indicative of the total wagered amount as well as eligibility information. The property-wide progressive jackpot controller 102 may receive this forwarded information and logically associate the wager with the property-wide progressive jackpot. The property-wide progressive jackpot controller 102 may then increase the property-wide progressive jackpot by at least a fraction of the wager and may assist the gaming device 104 in determining whether or not a player has won at least a portion of the property-wide progressive jackpot.
The bank-wide progressive jackpot controllers 106 may be configured to monitor and administer their respective bank-wide progressive jackpots, and may function generally similarly to the property-wide progressive jackpot controller 102. In one embodiment, the bank-wide progressive jackpot controllers 106 may also be configured similarly to the property-wide progressive jackpot controller 102.
Of course, in other embodiments, there need not be separate progressive jackpot controllers. For example, the individual and group progressive jackpots may be administered by the gaming devices 104 themselves in a distributed or peer-to-peer environment.

Description of an Exemplary Method for Enabling Participation in Progressive Jackpots
The method begins at 502, when a wager is accepted at a gaming device 104. The wager may be accepted at the gaming device 104 in a variety of ways. In one embodiment, a player may first purchase a number of credits on the gaming device 104. For example, the player may use one or more currency acceptors (e.g., a coin slot, or bill acceptor) or a financial card reader. The player may then provide user input via a user interface of the gaming device 104 indicating a desire to place the wager. Provided the wager meets certain criteria (e.g., the amount of the wager is not greater than the purchased credits), the gaming device 104 may then accept the wager. The amount of the wager may then be subtracted from the purchased credits.
At 504, the wager is logically associated with a first progressive jackpot, the first progressive jackpot associated with a first set of participating gaming devices. As discussed above, the first set of participating gaming devices may comprise any number of gaming devices. In one embodiment, the first set of participating gaming devices is defined by the gaming device 104 itself. In another embodiment, the first set of participating gaming devices may be defined by a bank 108 of the gaming devices 104 in the gaming property 100. In yet another embodiment, the first set of participating gaming devices may be defined by a plurality of gaming devices 104 located throughout the gaming property 100, or by a plurality of gaming devices in a plurality of gaming properties.
The logical association may be performed at any of a number of computing devices within or outside the gaming property 100, depending upon which gaming devices are included in the first set of participating gaming devices. In one embodiment, the gaming device 104 that has accepted the wager may store information indicative of the first progressive jackpot and may perform the logical association. In another embodiment, the gaming device 104 may accept the wager and then send information indicative of the wager to a progressive jackpot controller (e.g., the property-wide progressive jackpot controller 102 or one of the bank-wide progressive jackpot controllers 106). The progressive jackpot controller may receive this information and may then logically associate the wager with the respective progressive jackpot administered thereon.
A number of actions may be taken based at least in part on the above logical association. In one embodiment, at least a first fraction of the wager may be allocated to increase the first progressive jackpot. This allocation may occur at the gaming device 104 or at a progressive jackpot controller communicatively coupled to the gaming device 104, depending upon which computing device administers the first progressive jackpot. In one embodiment, the gaming device 104 may have stored thereon a table including an increment rate indicative of which fraction of the wager should be allocated to the first progressive jackpot and may itself increase the first progressive jackpot. In another embodiment, the gaming device 104 may determine the first fraction of the wager that should be allocated to the first progressive jackpot, and information indicative of this amount may be sent to a corresponding progressive jackpot controller.
In another embodiment, the first fraction allocated to the first progressive jackpot may be variable. When the first progressive jackpot is small, for example, the first fraction may be larger to increase the value of the first progressive jackpot more quickly. However, once the first progressive jackpot has reached a certain value, the first fraction may be reduced or eliminated.
At 506, the wager is logically associated with a second progressive jackpot different than the first progressive jackpot, the second progressive jackpot associated with a second set of participating gaming devices, the second set of participating gaming devices comprising more gaming devices than the first set of participating gaming devices. As described above, the second set of participating gaming devices may comprise any number of gaming devices greater than the number of gaming devices comprising the first set of participating gaming devices. Indeed, in some embodiments, the first set of participating gaming devices may comprise a subset of the second set of participating gaming devices. In one embodiment, the first set of participating gaming devices is defined by the gaming device 104 itself, and the second set of participating gaming devices may be defined by the bank 106 of the gaming devices 104 in the gaming property 100. In another embodiment, the first set of participating gaming devices may be defined by the bank 106 of the gaming devices 104 in the gaming property 100, and the second set of participating gaming devices may be defined by a plurality of gaming devices 104 located throughout the gaming property 100, or by a plurality of gaming devices in a plurality of gaming properties.
As described above with reference to act 504, the logical association may be performed at any of a number of computing devices within or outside the gaming property 100, depending upon which gaming devices define the second set of participating gaming devices. In one embodiment, the gaming device 104 that has accepted the wager may store information indicative of the second progressive jackpot and may perform the logical association. In another embodiment, the gaming device 104 may accept the wager and then send information indicative of the wager to a progressive jackpot controller (e.g., the property-wide progressive jackpot controller 102 or one of the bank-wide progressive jackpot controllers 106). The progressive jackpot controller may then logically associate the wager with the respective progressive jackpot administered thereon.
In one embodiment, at least a second fraction of the wager may be allocated to increase the second progressive jackpot. This allocation may occur at the gaming device 104 or at a progressive jackpot controller communicatively coupled to the gaming device 104, depending upon which computing device administers the second progressive jackpot.
The second fraction may also be larger than, equal to, or smaller than the first fraction. In one embodiment, the second fraction may be smaller than the first fraction, such that the first progressive jackpot, which is associated with fewer participating gaming devices, may increase more rapidly.
In one embodiment, the method described herein may further include enabling play of a game of chance on the gaming device 104. When playing the game of chance, the odds of winning the first progressive jackpot may be better than the odds of winning the second progressive jackpot. Thus, with more gaming devices participating in the second progressive jackpot, it may be made less likely that any particular wager will win the second progressive jackpot.
The foregoing detailed description has set forth various embodiments of the devices and/or processes via the use of block diagrams, schematics, and examples. Insofar as such block diagrams, schematics, and examples contain one or more functions and/or operations, it will be understood by those skilled in the art that each function and/or operation within such block diagrams, flowcharts, or examples can be implemented, individually and/or collectively, by a wide range of hardware, software, firmware, or virtually any combination thereof. In one embodiment, the present subject matter may be implemented via Application Specific Integrated Circuits (ASICs). However, those skilled in the art will recognize that the embodiments disclosed herein, in whole or in part, can be equivalently implemented in standard integrated circuits, as one or more programs executed by one or more processors, as one or more programs executed by one or more controllers (e.g., microcontrollers), as firmware, or as virtually any combination thereof, and that designing the circuitry and/or writing the code for the software and or firmware would be well within the skill of one of ordinary skill in the art in light of this disclosure.
When logic is implemented as software and stored in memory, one skilled in the art will appreciate that logic or information can be stored on any computer readable medium for use by or in connection with any processor-related system or method. In the context of this document, a memory is a computer-readable medium that is an electronic, magnetic, optical, or other physical device or means that contains or stores a computer and/or processor program. Logic and/or the information can be embodied in any computer-readable medium for use by or in connection with an instruction execution system, apparatus, or device, such as a computer-based system, processor-containing system, or other system that can fetch the instructions from the instruction execution system, apparatus, or device and execute the instructions associated with logic and/or information.
In the context of this specification, a “computer-readable medium” can be any means that can store the program associated with logic and/or information for use by or in connection with the instruction execution system, apparatus, and/or device. The computer-readable medium can be, for example, but is not limited to, an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus or device. More specific examples (a nonexhaustive list) of the computer readable medium would include the following: a portable computer diskette (magnetic, compact flash card, secure digital, or the like), a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM, EEPROM, or Flash memory), and a portable compact disc read-only memory (CDROM). Note that the computer-readable medium could even be paper or another suitable medium upon which the program associated with logic and/or information is printed, as the program can be electronically captured, via for instance optical scanning of the paper or other medium, then compiled, interpreted or otherwise processed in a suitable manner if necessary, and then stored in memory.
The various embodiments described above can be combined to provide further embodiments. From the foregoing it will be appreciated that, although specific embodiments have been described herein for purposes of illustration, various modifications may be made without deviating from the spirit and scope of the teachings. Accordingly, the claims are not limited by the disclosed embodiments.
