The present invention relates generally to gaming machines, and methods for playing wagering games, and more particularly, to a gaming system having one or more trigger time indicators.
Gaming machines, such as slot machines, video poker machines and the like, have been a cornerstone of the gaming industry for several years. Generally, the popularity of such machines with players is dependent on the likelihood (or perceived likelihood) of winning money at the machine and the intrinsic entertainment value of the machine relative to other available gaming options. Where the available gaming options include a number of competing machines and the expectation of winning at each machine is roughly the same (or believed to be the same), players are likely to be attracted to the most entertaining and exciting machines. Shrewd operators consequently strive to employ the most entertaining and exciting machines, features, and enhancements available because such machines attract frequent play and hence increase profitability to the operator. Therefore, there is a continuing need for gaming machine manufacturers to continuously develop new games and improved gaming enhancements that will attract frequent play through enhanced entertainment value to the player.
One concept that has been successfully employed to enhance the entertainment value of a game is the concept of a “secondary” or “bonus” game that may be played in conjunction with a “basic” game. The bonus game may comprise any type of game, either similar to or completely different from the basic game, which is entered upon the occurrence of a selected event or outcome in the basic game. Generally, bonus games provide a greater expectation of winning than the basic game and may also be accompanied with more attractive or unusual video displays and/or audio. Bonus games may additionally award players with “progressive jackpot” awards that are funded, at least in part, by a percentage of coin-in from the gaming machine or a plurality of participating gaming machines. Because the bonus game concept offers tremendous advantages in player appeal and excitement relative to other known games, and because such games are attractive to both players and operators, there is a continuing need to develop gaming systems with new types of bonus games to satisfy the demands of players and operators.
One concept which has been employed in gaming systems is the awarding of mystery prizes or jackpots. Traditionally, such prizes are awarded to players independently of gameplay, in other words, not as a function of obtaining a particular outcome on a wagering game. Rather, mystery prizes are awarded through various triggering mechanisms. One such triggering mechanism is providing a mystery prize to one or more players at randomly selected time periods. Another triggering mechanism is awarding mystery prizes after a predetermined amount of wagers are received from players of the gaming system. Yet another triggering mechanism involves randomly selecting a predetermined jackpot trigger value and awarding the mystery award or jackpot when the jackpot value reaches the trigger amount. In this latter triggering mechanism, the gaming system may or may not display information as to the range of trigger values. One problem which exists is that even when such a range is displayed, players are unaware if and when the jackpot is more likely to be triggered given the current status of the jackpot within such range. Another problem that exists is that such mystery jackpots offer only a single, relatively larger prize, which often causes long periods of time in between successive triggering events of the jackpot. The present invention is directed to solving these and other problems.
According to one aspect of the present invention, a gaming system comprises a wager input device for receiving at least one wager and one or more displays for displaying a randomly selected outcome of a wagering game. The one or more displays display a trigger time indicator. The gaming system further comprises at least one controller operative to (i) add a portion of the at least one wager to an actual turnover, (ii) randomly select a trigger amount from a range of available trigger amounts, (iii) calculate a time estimate when the actual turnover will become equal to or greater than the trigger amount based on a current turnover rate, (iv) update the trigger time indicator based on the time estimate, and (v) award a prize in response to the actual turnover becoming equal to or greater than the trigger amount.
According to another aspect of the invention, a method of conducting a wagering game on a gaming system comprises receiving a wager, displaying a randomly selected outcome of the wagering game, and adding at least a portion of the wager to an actual turnover. The method further comprises randomly selecting a trigger amount from a range of available trigger amounts, calculating a time estimate when the actual turnover will become equal to or greater than the trigger amount based on a current turnover rate, and displaying the time estimate on a trigger time indicator. The method further comprises awarding a prize in response to the actual turnover becoming equal to or greater than the trigger amount.
According to yet another aspect of the invention, a method of conducting wagering games on a gaming system comprises receiving a plurality of wagers, displaying a plurality of randomly selected outcomes of the wagering games, and displaying a plurality of progressive jackpots. The method further comprises apportioning a portion of the plurality of wagers and adding the portion to an actual turnover, distributing the portion among the plurality of progressive jackpots, and randomly selecting a trigger amount from a range of available trigger amounts. The method further comprises calculating a time estimate when the actual turnover will become equal to or greater than the trigger amount based on a current turnover rate, displaying the time estimate on a trigger time indicator, and awarding a randomly selected one of the progressive jackpots in response to the actual turnover becoming equal to or greater than the trigger amount.
According to another aspect of the invention, a gaming system comprises a plurality of gaming terminals, at least one wager input device associated with the plurality of gaming terminals, and at least one controller. Each gaming terminal comprises at least one primary display. Each gaming terminal is operative to (i) detect receipt of a wager for a wagering game displayed on the respective gaming terminal, and (ii) transfer an amount of the wager to the controller. The at least one controller is operative to (i) add a portion of the wager to an actual turnover for the plurality of gaming terminals, (ii) randomly select a trigger amount from a range of available trigger amounts, (iii) calculate a time estimate when the actual turnover will become equal to or greater than the trigger amount based on a current turnover rate at which wagers are received at the gaming terminals, (iv) update a trigger time indicator of the at least one display based on the time estimate, and (v) award a prize in response to the actual turnover becoming equal to or greater than the trigger amount.
According to yet another aspect of the invention, a gaming terminal comprises a value input device for receiving wagers and one or more displays for displaying a randomly selected outcome of a wagering game. The one or more displays further display a trigger time indicator. The gaming terminal further comprises a first controller operative to transfer an amount of each wager received to a second controller and cause the at least one display to display the trigger time indicator. The second controller is operative to (i) add a portion of each wager to an actual turnover, (ii) calculate a current turnover rate for the gaming terminal and any other eligible gaming terminals, (iii) determine a time estimate at which the actual turnover will reach a randomly selected trigger amount, and (iv) send the time estimate to the first controller to update the trigger time indicator. The time estimate is based upon the current turnover rate.
According to another aspect of the invention, a method of conducting a wagering game on a gaming system comprises receiving a wager and displaying a randomly selected outcome of a wagering game. The method further comprises calculating a clock time estimate when a special award will be triggered by a triggering event, displaying the clock time estimate on a trigger time indicator, and awarding the special award in response to the triggering event.
According to yet another aspect of the invention, a computer readable storage medium is encoded with instructions for directing a gaming system to perform the above methods.

Referring to
The gaming machine 10 comprises a housing 12 and includes input devices, including a value input device 18 and a player input device 24. For output the gaming machine 10 includes a primary display 14 for displaying information about the basic wagering game. The primary display 14 can also display information about a bonus wagering game and a progressive wagering game. The gaming machine 10 may also include a secondary display 16 for displaying game events, game outcomes, and/or signage information. While these typical components found in the gaming machine 10 are described below, it should be understood that numerous other elements may exist and may be used in any number of combinations to create various forms of a gaming machine 10.
The value input device 18 may be provided in many forms, individually or in combination, and is preferably located on the front of the housing 12. The value input device 18 receives currency and/or credits that are inserted by a player. The value input device 18 may include a coin acceptor 20 for receiving coin currency (see
The player input device 24 comprises a plurality of push buttons 26 on a button panel for operating the gaming machine 10. In addition, or alternatively, the player input device 24 may comprise a touch screen 28 mounted by adhesive, tape, or the like over the primary display 14 and/or secondary display 16. The touch screen 28 contains soft touch keys 30 denoted by graphics on the underlying primary display 14 and used to operate the gaming machine 10. The touch screen 28 provides players with an alternative method of input. A player enables a desired function either by touching the touch screen 28 at an appropriate touch key 30 or by pressing an appropriate push button 26 on the button panel. The touch keys 30 may be used to implement the same functions as push buttons 26. Alternatively, the push buttons 26 may provide inputs for one aspect of the operating the game, while the touch keys 30 may allow for input needed for another aspect of the game.
The various components of the gaming machine 10 may be connected directly to, or contained within, the housing 12, as seen in
The operation of the basic wagering game is displayed to the player on the primary display 14. The primary display 14 can also display the bonus game associated with the basic wagering game. The primary display 14 may take the form of a cathode ray tube (CRT), a high resolution LCD, a plasma display, an LED, or any other type of display suitable for use in the gaming machine 10. As shown, the primary display 14 includes the touch screen 28 overlaying the entire display (or a portion thereof) to allow players to make game-related selections. Alternatively, the primary display 14 of the gaming machine 10 may include a number of mechanical reels to display the outcome in visual association with at least one payline 32. In the illustrated embodiment, the gaming machine 10 is an “upright” version in which the primary display 14 is oriented vertically relative to the player. Alternatively, the gaming machine may be a “slant-top” version in which the primary display 14 is slanted at about a thirty-degree angle toward the player of the gaming machine 10.
A player begins play of the basic wagering game by making a wager via the value input device 18 of the gaming machine 10. A player can select play by using the player input device 24, via the buttons 26 or the touch screen keys 30. The basic game consists of a plurality of symbols arranged in an array, and includes at least one payline 32 that indicates one or more outcomes of the basic game. Such outcomes are randomly selected in response to the wagering input by the player. At least one of the plurality of randomly-selected outcomes may be a start-bonus outcome, which can include any variations of symbols or symbol combinations triggering a bonus game.
In some embodiments, the gaming machine 10 may also include a player information reader 52 that allows for identification of a player by reading a card with information indicating his or her true identity. The player information reader 52 is shown in
Depicted in
The player-accessible value input device 118 may comprise, for example, a slot located on the front, side, or top of the casing 112 configured to receive credit from a stored-value card (e.g., casino card, smart card, debit card, credit card, etc.) inserted by a player. In another aspect, the player-accessible value input device 118 may comprise a sensor (e.g., an RF sensor) configured to sense a signal (e.g., an RF signal) output by a transmitter (e.g., an RF transmitter) carried by a player. The player-accessible value input device 118 may also or alternatively include a ticket reader, or barcode scanner, for reading information stored on a credit ticket, a card, or other tangible portable credit or funds storage device. The credit ticket or card may also authorize access to a central account, which can transfer money to the handheld gaming machine 110.
Still other player-accessible value input devices 118 may require the use of touch keys 130 on the touch-screen display (e.g., primary display 114 and/or secondary display 116) or player input devices 124. Upon entry of player identification information and, preferably, secondary authorization information (e.g., a password, PIN number, stored value card number, predefined key sequences, etc.), the player may be permitted to access a player's account. As one potential optional security feature, the handheld gaming machine 110 may be configured to permit a player to only access an account the player has specifically set up for the handheld gaming machine 110. Other conventional security features may also be utilized to, for example, prevent unauthorized access to a player's account, to minimize an impact of any unauthorized access to a player's account, or to prevent unauthorized access to any personal information or funds temporarily stored on the handheld gaming machine 110.
The player-accessible value input device 118 may itself comprise or utilize a biometric player information reader which permits the player to access available funds on a player's account, either alone or in combination with another of the aforementioned player-accessible value input devices 118. In an embodiment wherein the player-accessible value input device 118 comprises a biometric player information reader, transactions such as an input of value to the handheld device, a transfer of value from one player account or source to an account associated with the handheld gaming machine 110, or the execution of another transaction, for example, could all be authorized by a biometric reading, which could comprise a plurality of biometric readings, from the biometric device.
Alternatively, to enhance security, a transaction may be optionally enabled only by a two-step process in which a secondary source confirms the identity indicated by a primary source. For example, a player-accessible value input device 118 comprising a biometric player information reader may require a confirmatory entry from another biometric player information reader 152, or from another source, such as a credit card, debit card, player ID card, fob key, PIN number, password, hotel room key, etc. Thus, a transaction may be enabled by, for example, a combination of the personal identification input (e.g., biometric input) with a secret PIN number, or a combination of a biometric input with a fob input, or a combination of a fob input with a PIN number, or a combination of a credit card input with a biometric input. Essentially, any two independent sources of identity, one of which is secure or personal to the player (e.g., biometric readings, PIN number, password, etc.) could be utilized to provide enhanced security prior to the electronic transfer of any funds. In another aspect, the value input device 118 may be provided remotely from the handheld gaming machine 110.
The player input device 124 comprises a plurality of push buttons on a button panel for operating the handheld gaming machine 110. In addition, or alternatively, the player input device 124 may comprise a touch screen mounted to a primary display 114 and/or secondary display 116. In one aspect, the touch screen is matched to a display screen having one or more selectable touch keys 130 selectable by a user's touching of the associated area of the screen using a finger or a tool, such as a stylus pointer. A player enables a desired function either by touching the touch screen at an appropriate touch key 130 or by pressing an appropriate push button 126 on the button panel. The touch keys 130 may be used to implement the same functions as push buttons 126. Alternatively, the push buttons may provide inputs for one aspect of the operating the game, while the touch keys 130 may allow for input needed for another aspect of the game. The various components of the handheld gaming machine 110 may be connected directly to, or contained within, the casing 112, as seen in
The operation of the basic wagering game on the handheld gaming machine 110 is displayed to the player on the primary display 114. The primary display 114 can also display the bonus game associated with the basic wagering game. The primary display 114 preferably takes the form of a high resolution LCD, a plasma display, an LED, or any other type of display suitable for use in the handheld gaming machine 110. The size of the primary display 114 may vary from, for example, about a 2-3″ display to a 15″ or 17″ display. In at least some aspects, the primary display 114 is a 7″-10″ display. As the weight of and/or power requirements of such displays decreases with improvements in technology, it is envisaged that the size of the primary display may be increased. Optionally, coatings or removable films or sheets may be applied to the display to provide desired characteristics (e.g., anti-scratch, anti-glare, bacterially-resistant and anti-microbial films, etc.). In at least some embodiments, the primary display 114 and/or secondary display 116 may have a 16:9 aspect ratio or other aspect ratio (e.g., 4:3). The primary display 114 and/or secondary display 116 may also each have different resolutions, different color schemes, and different aspect ratios.
As with the free standing gaming machine 10, a player begins play of the basic wagering game on the handheld gaming machine 110 by making a wager (e.g., via the value input device 18 or an assignment of credits stored on the handheld gaming machine via the touch screen keys 130, player input device 124, or buttons 126) on the handheld gaming machine 110. In at least some aspects, the basic game may comprise a plurality of symbols arranged in an array, and includes at least one payline 132 that indicates one or more outcomes of the basic game. Such outcomes are randomly selected in response to the wagering input by the player. At least one of the plurality of randomly selected outcomes may be a start-bonus outcome, which can include any variations of symbols or symbol combinations triggering a bonus game.
In some embodiments, the player-accessible value input device 118 of the handheld gaming machine 110 may double as a player information reader 152 that allows for identification of a player by reading a card with information indicating the player's identity (e.g., reading a player's credit card, player ID card, smart card, etc.). The player information reader 152 may alternatively or also comprise a bar code scanner, RFID transceiver or computer readable storage medium interface. In one presently preferred aspect, the player information reader 152, shown by way of example in

The controller 34 is also coupled to the system memory 36 and a money/credit detector 38. The system memory 36 may comprise a volatile memory (e.g., a random-access memory (RAM)) and a non-volatile memory (e.g., an EEPROM). The system memory 36 may include multiple RAM and multiple program memories. The money/credit detector 38 signals the processor that money and/or credits have been input via the value input device 18. Preferably, these components are located within the housing 12 of the gaming machine 10. However, as explained above, these components may be located outboard of the housing 12 and connected to the remainder of the components of the gaming machine 10 via a variety of different wired or wireless connection methods.
As seen in
Communications between the controller 34 and both the peripheral components of the gaming machine 10 and external systems 50 occur through input/output (I/O) circuits 46, 48. More specifically, the controller 34 controls and receives inputs from the peripheral components of the gaming machine 10 through the input/output circuits 46. Further, the controller 34 communicates with the external systems 50 via the I/O circuits 48 and a communication path (e.g., serial, parallel, IR, RC, 10bT, etc.). The external systems 50 may include a gaming network, other gaming machines, a gaming server, communications hardware, or a variety of other interfaced systems or components. Although the I/O circuits 46, 48 may be shown as a single block, it should be appreciated that each of the I/O circuits 46, 48 may include a number of different types of I/O circuits.
Controller 34, as used herein, comprises any combination of hardware, software, and/or firmware that may be disposed or resident inside and/or outside of the gaming machine 10 that may communicate with and/or control the transfer of data between the gaming machine 10 and a bus, another computer, processor, or device and/or a service and/or a network. The controller 34 may comprise one or more controllers or processors. In
The gaming machines 10, 110 may communicate with external systems 50 (in a wired or wireless manner) such that each machine operates as a “thin client,” having relatively less functionality, a “thick client,” having relatively more functionality, or through any range of functionality there between. As a generally “thin client,” the gaming machine may operate primarily as a display device to display the results of gaming outcomes processed externally, for example, on a server as part of the external systems 50. In this “thin client” configuration, the server executes game code and determines game outcomes (e.g., with a random number generator), while the controller 34 on board the gaming machine processes display information to be displayed on the display(s) of the machine. In an alternative “thicker client” configuration, the server determines game outcomes, while the controller 34 on board the gaming machine executes game code and processes display information to be displayed on the display(s) of the machines. In yet another alternative “thick client” configuration, the controller 34 on board the gaming machine 110 executes game code, determines game outcomes, and processes display information to be displayed on the display(s) of the machine. Numerous alternative configurations are possible such that the aforementioned and other functions may be performed onboard or external to the gaming machine as may be necessary for particular applications. It should be understood that the gaming machines 10, 110 may take on a wide variety of forms such as a free standing machine, a portable or handheld device primarily used for gaming, a mobile telecommunications device such as a mobile telephone or personal daily assistant (PDA), a counter top or bar top gaming machine, or other personal electronic device such as a portable television, MP3 player, entertainment device, etc.

The gaming system 300 may also include one or more secondary displays 316 for conveying and displaying jackpot information. In the embodiment shown in

The status labels 378 may include relevant alpha-numeric information which, in conjunction with the thermometer icon 376, conveys information relevant to an actual turnover 375 relative to an expected turnover value, as described in detail herein. In this embodiment, the status labels 378 include a plurality of “states” 380 (
In
However, when the actual turnover 375 exceeds the theoretical or expected value at which the mystery award 372 should be triggered ($2,000 in this case), then the state 380 indicates “Heat Wave,” “Super Heat Wave,” or “Mega Heat Wave” to subjectively communicate an increased probability of an imminent triggering event. In alternative embodiments, the E.V. indicator 374 may also include objective information such as the low end and high end values of the range 384, and the value of the actual turnover 375. However, in a preferred embodiment, only subjective information is conveyed by the E.V. indicator 374 so as to convey excitement and increase play of the gaming system 300, without revealing specific details of the exact values of the actual turnover 375 and the bounds of the range 384. As used herein, “turnover” refers to the accumulation of the portions of wagers input into the gaming system 300 that are dedicated to funding the mystery jackpot awards 372 that have not been triggered or awarded. Many other expected-value tables 382 may be utilized other than the one shown in
In the example shown in
In this embodiment, once the actual turnover 375 reaches the randomly selected turnover trigger value (e.g., $3,468.14), a jackpot triggering event has occurred. In some embodiments, the jackpot is triggered when the actual turnover 375 equals the randomly selected trigger value. In other embodiments, the actual turnover 375 must surpass, or be greater than, the selected trigger value for the jackpot to be triggered. In this embodiment, one of the four mystery jackpot awards 372 is randomly selected and awarded to the player whose wager contributed the incremental portion of turnover causing the jackpot triggering event. The mystery jackpot award 372 is randomly chosen in accordance with a weighted probability assigned to each of the four mystery jackpot awards 372. The weighted probabilities are stored in a data table (see
Turning to
Thus, for the higher level awards (larger amounts) the turnover is larger between triggering of such awards given the relatively lower probability of triggering them. In the fourth column 608 of the table 600, the Total EV is shown. This represents a percentage of wagers input into the gaming system that the operator has selected to have apportioned to fund the mystery awards 372. Thus, in this embodiment, the operator has configured the gaming system such that 5% of wagers input into the system are used to fund the mystery awards 372, and that of that 5%, 1.5% is used to fund the Level 1 award, 1.5% is used to fund the Level 2 award, 1.0% is used to fund the Level 3 award, and 1.0% is used to fund the Level 4 award (totaling 5%).
In the sixth column 612 of the table 600 are shown the Start-Up values of the various levels of the awards 372, which are selected and customizable by the operator of the gaming system. The start-up values (or reset values) represent an amount of money that the various awards 372 reset to after being triggered or awarded. Thus, after a Level 1 award is won and distributed, the Level 1 jackpot resets to a Start-Up value of $20.00 as seen in the table 600. The other start-up values for the other awards 372 are also shown. The seventh and eighth columns 614, 616 of the table 600 are the Start-Up EV and the Increment EV which represent the portions of the Total EV (fourth column 608) that fund the start up and incrementing, respectively, of each of the mystery awards 372. For example, looking at the Level 1 award, of the 1.50% Total EV for that award 372, a portion of it goes to funding the $20.00 start-up value when the Level 1 jackpot resets, and another portion of it goes to funding the incrementing of that jackpot. The Start-Up EV for each Level jackpot is a function of the operator's selected Start-Up value (column 612) and the Turnover (column 606). Specifically, the equation for the Start-Up EV is shown in Equation 2 below, showing an example calculation for the Start-Up EV for the Level 1 award:
Thus, of the 1.50% Total EV for the Level 1 award, 0.69% contributes to the funding of the $20.00 Start-Up value. The remainder of the Total EV funds the incrementing of the Level 1 award. Thus, the following equations show the relationship between Total EV, Start-Up EV and Increment EV (Equation 3), showing an example calculation for the Increment EV for the Level 1 award (Equation 4):
Total EV=Start Up EV+Increment EV Equation 3
Therefore:
Increment EV=Total EV−Start Up EV=1.50%−0.69%=0.81% Equation 4
Thus, of the 1.50% Total EV for the Level 1 award, 0.81% contributes to the funding of the incrementing of the Level 1 award.
In the fifth column 610 of the table 600 is shown the Strike value for each of the various levels of awards 372. The Strike value represents the average value of the different levels of awards 372 when they are awarded. Of course on individual instances, the actual value of the award may be greater than, less than, or equal to the Strike value. But on average, the value of the awards will be the Strike values shown in the table 600. Thus, the average value, or strike value of the Level 1 award is $43.48. The strike values of the awards for Levels 2, 3, and 4, respectively, are $150.00, $200.00, and $2,000.00. The Strike value for a particular award 372 is a function of the Start Up value (column 612), the Turnover (column 606), and the IncrementEV (column 614). Specifically, the Strike value is governed by the Equation 5 below, showing an example calculation for the Strike value of the Level 1 award:
Strike=StartUp+(Turnover)(Increment EV)=$20.00+($2,898.55)(0.0081)=$43.48 Equation 5
Therefore, the data table 600 shows the mathematics used for apportioning portions of received wagers and using the apportioned amounts to fund the various levels of jackpots. The table 600 also shows what the theoretical strike values of the jackpots are and the average turnover required for each jackpot to be triggered. The data in the table 600 is provided by way of example, but many other configurations of the data table 600 are possible. The operator customizable features (such as the Total EV and the Start-Up Values) affect many of the results shown in the table 600, and would be different for differing inputs selected by the operator. Many configurations are possible.

As with other embodiments, a plurality of gaming machines or terminals are in communication with a central controller which controls a trigger time indicator (not shown). Players at the various gaming terminals place wagers and execute plays of wagering games displayed on their gaming terminals. Portions of each such wager are used to increment the progressive jackpots 372a-d. As previously described, the controller of the gaming system 300, in one example, randomly selects a trigger amount (e.g., turnover trigger value) between a minimum trigger value and a maximum trigger value, which in this embodiment is again between zero and $4,000. As players play the gaming system 300, portions of their wager inputs are used to fund and increment the actual turnover, which in turn are apportioned to the various mystery jackpot awards 372. The controller in one example is operative to calculate a time estimate when the actual turnover will become equal to or greater than the trigger amount, for example, a trigger time estimate or a projected time until a jackpot triggering event occurs. This time estimate may be based on the trigger amount, the actual turnover, and a current turnover rate, as described herein.
The controller in this embodiment determines the current turnover rate as a sum of all portions of the wager inputs received at all gaming terminals during a previous time interval. In one example, the controller uses a fixed time interval, such as 30 or 60 seconds. In other examples, the length of the time interval may be set by an operator of the gaming system 300 and/or dynamically adjusted by the controller or other hardware and/or software. Additionally, the controller may round and/or truncate the current turnover rate up, down, or to a nearest value of a plurality of predetermined values. The current turnover rate may be expressed as “dollars received per interval”. The controller in one example calculates the trigger time estimate as:
time estimate=(trigger amount−actual turnover)/current turnover rate.
As one example, for a trigger amount of $3800, an actual turnover of $2200, and a current turnover rate of $75 per 60 second interval, the calculated trigger time estimate is 21.33 minutes. Thus, in such an example, the controller has randomly selected a trigger amount of $3800, has recognized that an actual turnover of $2200 has been collected so far (since the last jackpot triggering event), and calculated that in the past interval (60 seconds), $75.00 of turnover has been collected (based upon portions of wagers received from all gaming terminals). In alternative implementations, the controller may receive a value for the turnover rate from an external source or another controller.
To convey excitement and increase play of the gaming system 300, the controller is operative to display the trigger time estimate to players of the gaming system 300 or others in the vicinity of the gaming system 300 (e.g., within viewing distance of a community display). Turning to
The trigger time indicators 1002, 1004 in one example show a display message 1006 with the trigger time estimate. As shown in
The controller in one example is operative to activate and deactivate the trigger time indicators 1002, 1004 based on the trigger time estimate. For example, when the trigger time estimate is less than a first predetermined threshold, the controller is operative to activate the trigger time indicators 1002, 1004. Similarly, when the trigger time estimate is greater than a second predetermined threshold that is relatively large (e.g., 30 minutes or more), the controller is operative to deactivate the trigger time indicators 1002, 1004. In one example, activation of the trigger time indicators 1002, 1004 causes the trigger time indicators 1002, 1004 to power up or turn on their display. Conversely, deactivation of the trigger time indicators 1002, 1004 causes the trigger time indicators 1002, 1004 to power down or go into a power saving mode with a blank display. In another example, activation causes the trigger time indicators 1002, 1003 to display the calculated trigger time. Conversely, deactivation causes the trigger time indicators 1002, 1004 to clear their displays, display an alternate message, or fulfill another function as needed by the gaming system 300. In yet another example, activating the trigger time indicators 1002, 1004 comprises adding them to their respective displays 316, 314, while deactivating the trigger time indicators 1002, 1004 comprises removing them from their respective displays 316, 314. Regardless of whether or not the trigger time indicators 1002, 1004 are displayed, the controller may continue to calculate the trigger time as described herein. Thus, when the calculated trigger time falls below the first predetermined threshold, the trigger time indicators 1002 ,1004 are activated. In the example shown in

The controller in one example calculates the trigger time estimate at a first frequency and updates the trigger time indicator at a second frequency. The first and second frequencies in one example are predetermined and/or selected by the operator of the gaming system 300. In another example, the controller dynamically adjusts the first and/or second frequencies based on the time estimate. For example, as the time estimate falls under 60 seconds, the controller may update the trigger time indicator every 5 seconds. In another example, if the time estimate is larger than 20 minutes, the controller may update the trigger time indicator every 2 minutes. The controller may receive information from a variety of external sources and use such information to determine whether a change in either the first or second frequencies is necessary or desirable.
In one implementation, the controller is operative to adjust the time estimate before updating the trigger time indicator. For example, the operator of the gaming system 300 may desire to reduce a sensitivity of the time estimate in order to reduce the likelihood of the time estimate quickly alternating between two adjacent values. The controller in one example performs an average of the time estimate with one or more previous time estimates to reduce the sensitivity. In yet another example, the controller rounds and/or truncates the time estimate up, down, to a nearest value of a plurality of predetermined values, or a combination thereof. The operator of the gaming system 300 in one example selects predetermined values of 20, 15, 10, 5, 2, and 1 minute. In a still further example, the controller may round down to a first predetermined value (e.g., 1 minute) when the time estimate is within a selected range of the predetermined value (e.g., within 20 seconds) but not fall back to the previous predetermined value (e.g., 2 minutes) until the time estimate has increased to within a second predetermined range (e.g., 5 seconds) of the previous predetermined value. In this example, the time estimate has a greater tendency to fall than to rise.
Referring again to
In one implementation with a plurality of trigger time indicators, the controller maintains a corresponding plurality of time estimates. The controller may use different values for the first frequency, second frequency, display messages, or other parameters for each trigger time indicator. In one example, a trigger time indicator shown on a primary display of a gaming terminal occupied by a preferred player is maintained by the controller with a preferred set of parameters. For example, the controller may update the trigger time indicator for the preferred player more often or provide more accurate time estimates.

The gaming systems of the present invention offer a number of benefits to players of the wagering game 360. Firstly, the E.V. indicator of the present invention permits players to be aware of the relative value of the actual turnover within a range of turnovers, so as to be able to assess whether there is a relatively increased or decreased likelihood of a jackpot being triggered. The E.V. indicator communicates to players if the actual turnover is above its theoretical average, thereby making it more likely that a jackpot triggering event will occur imminently. Moreover, the plurality of mystery awards or jackpots permits more frequent triggering of a mystery prize, as compared to single-prize progressives. The combination of using actual turnover as a triggering mechanism, coupled with the random selection of a progressive jackpot according to a weighted probability table, creates an enjoyable mystery prize for players and benefits operators of gaming systems by stimulating frequent and frenzied wagering. Moreover, the trigger time indicator provides an additional mechanism for causing excitement and anticipation in players of the gaming system, as well as observers. By displaying to such players and observers the projected time until a triggering event occurs, the system optimizes opportunity to cause players to wager faster or in greater amounts in an attempt to more quickly bring about the triggering event. Additionally, the imminent nature of the triggering event creates a frenzy atmosphere as players compete to be the one causing the triggering event and thus being the recipient of the selected progressive jackpot to be awarded in response thereto.
Each of these embodiments and obvious variations thereof is contemplated as falling within the spirit and scope of the claimed invention, which is set forth in the following claims.
