Gaming machines which provide players awards in primary or base games are well known. Gaming machines generally require the player to place or make a wager to activate the primary or base game. In many of these gaming machines, the award is based on the player obtaining a winning symbol or symbol combination and is also based on the amount of the wager (e.g., the higher the wager, the higher the award). Generally, symbols or symbol combinations which are less likely to occur provide higher awards. In such known gaming machines, the amount of the wager made on the base game by the player can vary.
Certain known gaming machines provide reel games implemented using a plurality of independent reels, wherein each independent reel is configured to generate a single symbol for a spin of the reel. Such gaming machines display the plurality of independent reels in a matrix or other arrangement of independent reels. For a play of a game provided by such gaming machines, the gaming machine generates and displays a plurality of symbols by spinning each independent reel. The gaming machine provides an award for any winning symbol or winning symbol combination displayed by the plurality of independent reels.
Symbol stacking in a reel game is also known. Symbol stacking is implemented by forming stacks of one or more identical symbols in adjacent symbol positions of a reel strip utilized by a single reel. The identical symbols on the same single reel are adjacent to each other, and thus “stacked.” For example, in a slot game with three rows of symbols, three cherry symbols may appear adjacent to each other on a reel to form a stack of three cherry symbols. For a spin of the stacked reel of such a slot game, part or all of a stack of symbols can be displayed in a viewing area of the gaming machine. In one known slot gaming device, when a gaming machine generates stacks of symbols that are identical on three or more adjacent reels, multiple winning symbol combinations can be formed and the gaming machine can provide large payouts to the player if portions of one or more stacks of symbols are displayed.
Gaming machines which provide cascading symbol games are also known. In one such cascading symbol game, a gaming machine generates and displays a plurality of symbols in a plurality of symbol positions. The gaming machine evaluates the displayed symbols and provides an award for each winning symbol combination formed. The gaming machine then removes the displayed symbols that form the winning symbol combination(s) to create one or more empty symbol positions. The gaming machine shifts zero, one, or more of the remaining displayed symbols downward into zero, one, or more of the empty symbol positions and generates and displays a symbol for each remaining empty symbol position. The gaming machine re-evaluates the displayed symbols, provides an award for any displayed winning symbol combinations and repeats the steps of removing symbols, shifting symbols, generating new symbols, and evaluating symbol combinations until no winning symbol combination is displayed.
There is a continuing need to increase the excitement and entertainment experienced by people playing gaming machines. There is a further need for increasing the number of winning symbol combinations generated and awards provided to a player for a single play of a game.
The present disclosure relates generally to gaming systems and methods for providing a cascading or tumbling symbol game including a plurality of independent reels with stacked symbols. More particularly, the present disclosure relates to a gaming system which includes a plurality of independent reels arranged as a matrix of independent reels. Each independent reel is associated with a virtual reel strip which includes a plurality of symbols in a plurality of symbol positions, wherein the symbols are displayable for spins of that independent reel. Each symbol of each independent reel also has a probability of being generated for a spin of that independent reel. At least two adjacent independent reels are each associated with a virtual reel strip which provides a relatively high probability of generating a same designated symbol. Moreover, at least one of the plurality of independent reels is associated with a virtual reel strip having a same designated symbol in a plurality of adjacent symbol positions of that virtual reel strip.
In operation of one embodiment, the gaming system disclosed herein generates one of the symbols of each independent reel by randomly selecting that symbol from among the plurality of symbols of each associated virtual reel strip. The gaming system provides an award based on any generated winning symbol combinations. In one embodiment, the gaming system then generates a different symbol for at least one of the independent reels, such as by displaying a symbol which is adjacent to a previously displayed symbol of a virtual reel strip. The gaming system determines whether any new winning symbol combinations are displayed and provides any appropriate award. Since, as described above, at least two adjacent independent reels are each associated with a virtual reel strip having a relatively high probability of generating the same designated symbol, the gaming system provides a stacked symbol effect with respect to the designated symbol for each new symbol generation. Moreover, since the gaming system includes at least one independent reel associated with a reel strip having a plurality of adjacent designated symbols, the gaming system also provides a stacked symbol effect with respect to the designated symbol for each re-generation of a symbol for such stacked independent reels. Thus, the gaming system is relatively likely to display the designated symbol for a plurality of subsequent generations by that independent reel, increasing the probability of winning multiple awards for a play of the game.
In one embodiment, the gaming system disclosed herein includes a plurality of independent reels displayed as a matrix of independent reels. Each independent reel includes a plurality of symbols in a plurality of symbol positions, wherein any of the symbols can be generated for a spin of that independent reel. In one embodiment, each independent reel is associated with a virtual reel strip which includes a plurality of symbols. In another embodiment, each independent reel utilizes a table including a plurality of symbols. In various embodiments, each symbol of each independent reel includes a probability of being generated for a spin of that independent reel. For example, a first independent reel utilizes a reel strip including a designated symbol, the symbols of the first independent reel being generated in accordance with an 80% chance of generating the designated symbol. In this example, a second independent reel utilizes a reel strip which generates symbols in accordance with a 70% chance of generating the same designated symbol.
In one embodiment, the gaming system is configured such that at least two adjacent independent reels each utilize a table and/or a virtual reel strip which includes a relatively high probability of generating a same designated symbol. In one such embodiment, each of the adjacent independent reels utilizes a same reel strip. In another embodiment, each of the adjacent independent reels utilize different virtual reel strips having different (and relatively high) probabilities of generating the same designated symbol. Continuing with the example discussed above, the first and second tables are utilized by independent reels which are adjacent to one another such that each adjacent independent reel has at least a 70% chance of generating the designated symbol for a spin of each symbol generation or re-generation of that independent reel. It should be appreciated that this arrangement of independent reels (i.e., adjacent independent reels which each have at least a 70% percent chance of generating the designated symbol) results in the stacked symbol effect with respect to the designated symbol for an initial, random generation by the plurality of independent reels due to the relatively high likelihood of simultaneously generating the designated symbol for at least two adjacent independent reels.
In one embodiment, at least one of the independent reels provides a stacked symbol effect with respect to the designated symbol. In this embodiment, any independent reel which provides a stacked symbol effect includes a plurality of symbols displayed in a plurality of symbol positions of a virtual reel strip, wherein at least two adjacent symbol positions of the virtual reel strip include the designated symbol. For such a stacked independent reel, the gaming system is relatively likely to generate and display the designated symbol a plurality of times for a plurality of symbol generations. For example, the virtual reel strip of a stacked independent reel includes the designated symbol in four adjacent symbol positions.
In one embodiment, for a play of the game, the gaming system randomly generates and displays a symbol for each independent reel (such as by spinning the independent reels) based on the probabilities defined by the virtual reel strip or table utilized by that independent reel. In this embodiment, the gaming system determines whether the displayed symbols form any winning symbol combinations. If any winning symbol combinations are formed, the gaming system provides an award for such winning symbol combinations. In one embodiment, the gaming system determines at least one independent reel for which to regenerate a symbol by displaying a symbol in an adjacent symbol position of the virtual reel strip. In one embodiment, the gaming system determines such an independent reel based on the independent reels which displayed a symbol included in a winning symbol combination. In another embodiment, the gaming system determines such an independent reel based on independent reels which displayed the designated symbol. In one embodiment, for each determined independent reel, the gaming system activates that independent reel to display a symbol of an adjacent symbol position of the virtual reel strip associated with that independent reel. The gaming system determines whether any new winning symbol combinations are displayed and provides an award for such newly displayed winning symbol combinations. In the example discussed above, wherein at least one of the reels includes five adjacent designated symbols, the gaming system displays a first one of the five adjacent designated symbols for an initial generation of symbols, and displays a second one of the five adjacent symbols upon the re-generation for the play of the game. It should be appreciated that in this example, the gaming system can display the designated symbol for as many as five generations of symbols for the at least one example independent reel.
It should be appreciated that by providing a plurality of independent reels wherein at least two adjacent independent reels each have a relatively high probability of generating a same designated symbol, the disclosed gaming system provides a game having a stacked symbol effect with respect to the designated symbol for an initial generation of symbols. That is, the disclosed gaming system provides an increased probability of generating winning symbol combinations or winning symbol combinations associated with higher award values based on the relatively high probability of generating designated symbols for initial spins of two or more adjacent independent reels. Moreover, because the designated symbols are in adjacent symbol positions of a virtual reel strip (i.e., the symbols are stacked) for one or more of the independent reels, an activation of such an independent reel to display an adjacent symbol to the currently displayed designated symbol has a relatively high probability of displaying another designated symbol. Thus, the stacked symbol effect provided by the disclosed gaming system increases the probability of generating a plurality of different winning symbol combinations for a play of the game.
Additional features and advantages are described in, and will be apparent from, the following Detailed Description and the figures.

The player can increase the bet by one credit each time the player pushes the bet one button. When the player pushes the bet one button, the number of credits shown in the credit display preferably decreases by one, and the number of credits shown in the bet display preferably increases by one. In another embodiment, one input device is a bet max button (not shown) which enables the player to bet the maximum wager permitted for a game of the gaming device.
In one embodiment, one input device is a cash out button 34. The player may push the cash out button and cash out to receive a cash payment or other suitable form of payment corresponding to the number of remaining credits. In one embodiment, when the player cashes out, a payment device, such as a ticket, payment, or note generator 36 prints or otherwise generates a ticket or credit slip to provide to the player. The player receives the ticket or credit slip and may redeem the value associated with the ticket or credit slip via a cashier (or other suitable redemption system). In another embodiment, when the player cashes out, the player receives the coins or tokens in a coin payout tray. It should be appreciated that any suitable payout mechanisms, such as funding to the player's electronically recordable identification card or smart card, may be implemented in accordance with the gaming device disclosed herein.
In one embodiment, as mentioned above and as seen in
The gaming device may further include a plurality of communication ports for enabling communication of the processor with external peripherals, such as external video sources, expansion buses, game or other displays, a SCSI port, or a keypad.
In one embodiment, as seen in
In one embodiment, the gaming machine may include a sensor, such as a camera, in communication with the processor (and possibly controlled by the processor), that is selectively positioned to acquire an image of a player actively using the gaming device and/or the surrounding area of the gaming device. In one embodiment, the camera may be configured to selectively acquire still or moving (e.g., video) images and may be configured to acquire the images in an analog, digital, or other suitable format. The display devices may be configured to display the image acquired by the camera as well as to display the visible manifestation of the game in split screen or picture-in-picture fashion. For example, the camera may acquire an image of the player and the processor may incorporate that image into the primary and/or secondary game as a game image, symbol or indicia.
Gaming device 10 can incorporate any suitable wagering game as the primary or base game. The gaming machine or device may include some or all of the features of conventional gaming machines or devices. The primary or base game may comprise any suitable reel-type game, card game, cascading or falling symbol game, number game, or other game of chance susceptible to representation in an electronic or electromechanical form, which in one embodiment produces a random outcome based on probability data at the time of or after placement of a wager. That is, different primary wagering games, such as video poker games, video blackjack games, video keno, video bingo or any other suitable primary or base game may be implemented.
In one embodiment, as illustrated in
In an alternative embodiment, rather than determining any outcome to provide to the player by analyzing the symbols generated on any wagered upon paylines as described above, the gaming device determines any outcome to provide to the player based on the number of associated symbols which are generated in active symbol positions on the requisite number of adjacent reels (i.e., not on paylines passing through any displayed winning symbol combinations). In this embodiment, if a winning symbol combination is generated on the reels, the gaming device provides the player one award for that occurrence of the generated winning symbol combination. For example, if one winning symbol combination is generated on the reels, the gaming device will provide a single award to the player for that winning symbol combination (i.e., not based on the number of paylines that would have passed through that winning symbol combination). It should be appreciated that because a gaming device that enables wagering on ways to win provides the player one award for a single occurrence of a winning symbol combination and a gaming device with paylines may provide the player more than one award for the same occurrence of a single winning symbol combination (i.e., if a plurality of paylines each pass through the same winning symbol combination), it is possible to provide a player at a ways to win gaming device with more ways to win for an equivalent bet or wager on a traditional slot gaming device with paylines.
In one embodiment, the total number of ways to win is determined by multiplying the number of symbols generated in active symbol positions on a first reel by the number of symbols generated in active symbol positions on a second reel by the number of symbols generated in active symbol positions on a third reel and so on for each reel of the gaming device with at least one symbol generated in an active symbol position. For example, a three reel gaming device with three symbols generated in active symbol positions on each reel includes 27 ways to win (i.e., 3 symbols on the first reel×3 symbols on the second reel×3 symbols on the third reel). A four reel gaming device with three symbols generated in active symbol positions on each reel includes 81 ways to win (i.e., 3 symbols on the first reel×3 symbols on the second reel×3 symbols on the third reel×3 symbols on the fourth reel). A five reel gaming device with three symbols generated in active symbol positions on each reel includes 243 ways to win (i.e., 3 symbols on the first reel×3 symbols on the second reel×3 symbols on the third reel×3 symbols on the fourth reel×3 symbols on the fifth reel). It should be appreciated that modifying the number of generated symbols by either modifying the number of reels or modifying the number of symbols generated in active symbol positions by one or more of the reels modifies the number of ways to win.
In another embodiment, the gaming device enables a player to wager on and thus activate symbol positions. In one such embodiment, the symbol positions are on the reels. In this embodiment, if based on the player's wager, a reel is activated, then each of the symbol positions of that reel will be activated and each of the active symbol positions will be part of one or more of the ways to win. In one embodiment, if based on the player's wager, a reel is not activated, then a designated number of default symbol positions, such as a single symbol position of the middle row of the reel, will be activated and the default symbol position(s) will be part of one or more of the ways to win. This type of gaming machine enables a player to wager on one, more than one or all of the reels and the processor of the gaming device uses the number of wagered on reels to determine the active symbol positions and the number of possible ways to win. In alternative embodiments, (1) no symbols are displayed as generated at any of the inactive symbol positions, or (2) any symbols generated at any inactive symbol positions may be displayed to the player but suitably shaded or otherwise designated as inactive.
In one embodiment wherein a player wagers on one or more reels, a player's wager of one credit may activate each of the three symbol positions on a first reel, wherein one default symbol position is activated on each of the remaining four reels. In this example, as described above, the gaming device provides the player three ways to win (i.e., 3 symbols on the first reel×1 symbol on the second reel×1 symbol on the third reel×1 symbol on the fourth reel×1 symbol on the fifth reel). In another example, a player's wager of nine credits may activate each of the three symbol positions on a first reel, each of the three symbol positions on a second reel and each of the three symbol positions on a third reel wherein one default symbol position is activated on each of the remaining two reels. In this example, as described above, the gaming device provides the player twenty-seven ways to win (i.e., 3 symbols on the first reel×3 symbols on the second reel×3 symbols on the third reel×1 symbol on the fourth reel×1 symbol on the fifth reel).
In one embodiment, to determine any award(s) to provide to the player based on the generated symbols, the gaming device individually determines if a symbol generated in an active symbol position on a first reel forms part of a winning symbol combination with or is otherwise suitably related to a symbol generated in an active symbol position on a second reel. In this embodiment, the gaming device classifies each pair of symbols which form part of a winning symbol combination (i.e., each pair of related symbols) as a string of related symbols. For example, if active symbol positions include a first cherry symbol generated in the top row of a first reel and a second cherry symbol generated in the bottom row of a second reel, the gaming device classifies the two cherry symbols as a string of related symbols because the two cherry symbols form part of a winning symbol combination.
After determining if any strings of related symbols are formed between the symbols on the first reel and the symbols on the second reel, the gaming device determines if any of the symbols from the next adjacent reel should be added to any of the formed strings of related symbols. In this embodiment, for a first of the classified strings of related symbols, the gaming device determines if any of the symbols generated by the next adjacent reel form part of a winning symbol combination or are otherwise related to the symbols of the first string of related symbols. If the gaming device determines that a symbol generated on the next adjacent reel is related to the symbols of the first string of related symbols, that symbol is subsequently added to the first string of related symbols. For example, if the first string of related symbols is the string of related cherry symbols and a related cherry symbol is generated in the middle row of the third reel, the gaming device adds the related cherry symbol generated on the third reel to the previously classified string of cherry symbols.
On the other hand, if the gaming device determines that no symbols generated on the next adjacent reel are related to the symbols of the first string of related symbols, the gaming device marks or flags such string of related symbols as complete. For example, if the first string of related symbols is the string of related cherry symbols and none of the symbols of the third reel are related to the cherry symbols of the previously classified string of cherry symbols, the gaming device marks or flags the string of two cherry symbols as complete.
After either adding a related symbol to the first string of related symbols or marking the first string of related symbols as complete, the gaming device proceeds as described above for each of the remaining classified strings of related symbols which were previously classified or formed from related symbols on the first and second reels.
After analyzing each of the remaining strings of related symbols, the gaming device determines, for each remaining pending or incomplete string of related symbols, if any of the symbols from the next adjacent reel, if any, should be added to any of the previously classified strings of related symbols. This process continues until either each string of related symbols is complete or there are no more adjacent reels of symbols to analyze. In this embodiment, where there are no more adjacent reels of symbols to analyze, the gaming device marks each of the remaining pending strings of related symbols as complete.
When each of the strings of related symbols is marked complete, the gaming device compares each of the strings of related symbols to an appropriate paytable and provides the player any award associated with each of the completed strings of symbols. It should be appreciated that the player is provided one award, if any, for each string of related symbols generated in active symbol positions (i.e., as opposed to a quantity of awards being based on how many paylines that would have passed through each of the strings of related symbols in active symbol positions).
In one embodiment, a base or primary game may be a poker game wherein the gaming device enables the player to play a conventional game of video draw poker and initially deals five cards all face up from a virtual deck of fifty-two cards. Cards may be dealt as in a traditional game of cards or in the case of the gaming device, the cards may be randomly selected from a predetermined number of cards. If the player wishes to draw, the player selects the cards to hold via one or more input devices, such as by pressing related hold buttons or via the touch screen. The player then presses the deal button and the unwanted or discarded cards are removed from the display and the gaming machine deals the replacement cards from the remaining cards in the deck. This results in a final five-card hand. The gaming device compares the final five-card hand to a payout table which utilizes conventional poker hand rankings to determine the winning hands. The gaming device provides the player with an award based on a winning hand and the number of credits the player wagered.
In another embodiment, the base or primary game may be a multi-hand version of video poker. In this embodiment, the gaming device deals the player at least two hands of cards. In one such embodiment, the cards are the same cards. In one embodiment each hand of cards is associated with its own deck of cards. The player chooses the cards to hold in a primary hand. The held cards in the primary hand are also held in the other hands of cards. The remaining non-held cards are removed from each hand displayed and for each hand replacement cards are randomly dealt into that hand. Since the replacement cards are randomly dealt independently for each hand, the replacement cards for each hand will usually be different. The poker hand rankings are then determined hand by hand against a payout table and awards are provided to the player.
In one embodiment, a base or primary game may be a keno game wherein the gaming device displays a plurality of selectable indicia or numbers on at least one of the display devices. In this embodiment, the player selects at least one bit potentially a plurality of the selectable indicia or numbers via an input device such as a touch screen. The gaming device then displays a series of drawn numbers and determine an amount of matches, if any, between the players selected numbers and the gaming device's drawn numbers. The player is provided an award based on the amount of matches, if any, based on the amount of determined matches and the number of numbers drawn.
In one embodiment, in addition to winning credits or other awards in a base or primary game, the gaming device may also give players the opportunity to win credits in a bonus or secondary game or in a bonus or secondary round. The bonus or secondary game enables the player to obtain a prize or payout in addition to the prize or payout, if any, obtained from the base or primary game. In general, a bonus or secondary game produces a significantly higher level of player excitement than the base or primary game because it provides a greater expectation of winning than the base or primary game, and is accompanied with more attractive or unusual features than the base or primary game. In one embodiment, the bonus or secondary game may be any type of suitable game, either similar to or completely different from the base or primary game.
In one embodiment, the triggering event or qualifying condition may be a selected outcome in the primary game or a particular arrangement of one or more indicia on a display device in the primary game, such as the number seven appearing on three adjacent reels along a payline in the primary slot game embodiment seen in
In another embodiment, the gaming device processor 12 or central controller 56 randomly provides the player one or more plays of one or more secondary games. In one such embodiment, the gaming device does not provide any apparent reason to the player for qualifying to play a secondary or bonus game. In this embodiment, qualifying for a bonus game is not triggered by an event in or based specifically on any of the plays of any primary game. That is, the gaming device may simply qualify a player to play a secondary game without any explanation or alternatively with simple explanations. In another embodiment, the gaming device (or central server) qualifies a player for a secondary game at least partially based on a game triggered or symbol triggered event, such as at least partially based on the play of a primary game.
In one embodiment, the gaming device includes a program which will automatically begin a bonus round after the player has achieved a triggering event or qualifying condition in the base or primary game. In another embodiment, after a player has qualified for a bonus game, the player may subsequently enhance his/her bonus game participation through continued play on the base or primary game. Thus, for each bonus qualifying event, such as a bonus symbol, that the player obtains, a given number of bonus game wagering points or credits may be accumulated in a “bonus meter” programmed to accrue the bonus wagering credits or entries toward eventual participation in a bonus game. The occurrence of multiple such bonus qualifying events in the primary game may result in an arithmetic or exponential increase in the number of bonus wagering credits awarded. In one embodiment, the player may redeem extra bonus wagering credits during the bonus game to extend play of the bonus game.
In one embodiment, no separate entry fee or buy-in for a bonus game is needed. That is, a player may not purchase entry into a bonus game; rather they must win or earn entry through play of the primary game, thus encouraging play of the primary game. In another embodiment, qualification of the bonus or secondary game is accomplished through a simple “buy-in” by the player—for example, if the player has been unsuccessful at qualifying through other specified activities. In another embodiment, the player must make a separate side-wager on the bonus game or wager a designated amount in the primary game to qualify for the secondary game. In this embodiment, the secondary game triggering event must occur and the side-wager (or designated primary game wager amount) must have been placed to trigger the secondary game.
In one embodiment, as illustrated in
In one embodiment, the game outcome provided to the player is determined by a central server or controller and provided to the player at the gaming device. In this embodiment, each of a plurality of such gaming devices are in communication with the central server or controller. Upon a player initiating game play at one of the gaming devices, the initiated gaming device communicates a game outcome request to the central server or controller.
In one embodiment, the central server or controller receives the game outcome request and randomly generates a game outcome for the primary game based on probability data. In another embodiment, the central server or controller randomly generates a game outcome for the secondary game based on probability data. In another embodiment, the central server or controller randomly generates a game outcome for both the primary game and the secondary game based on probability data. In this embodiment, the central server or controller is capable of storing and utilizing program code or other data similar to the processor and memory device of the gaming device.
In an alternative embodiment, the central server or controller maintains one or more predetermined pools or sets of predetermined game outcomes. In this embodiment, the central server or controller receives the game outcome request and independently selects a predetermined game outcome from a set or pool of game outcomes. The central server or controller flags or marks the selected game outcome as used. Once a game outcome is flagged as used, it is prevented from further selection from the set or pool and cannot be selected by the central controller or server upon another wager. The provided game outcome can include a primary game outcome, a secondary game outcome, primary and secondary game outcomes, or a series of game outcomes such as free games.
The central server or controller communicates the generated or selected game outcome to the initiated gaming device. The gaming device receives the generated or selected game outcome and provides the game outcome to the player. In an alternative embodiment, how the generated or selected game outcome is to be presented or displayed to the player, such as a reel symbol combination of a slot machine or a hand of cards dealt in a card game, is also determined by the central server or controller and communicated to the initiated gaming device to be presented or displayed to the player. Central production or control can assist a gaming establishment or other entity in maintaining appropriate records, controlling gaming, reducing and preventing cheating or electronic or other errors, reducing or eliminating win-loss volatility, and the like.
In another embodiment, a predetermined game outcome value is determined for each of a plurality of linked or networked gaming devices based on the results of a bingo, keno, or lottery game. In this embodiment, each individual gaming device utilizes one or more bingo, keno, or lottery games to determine the predetermined game outcome value provided to the player for the interactive game played at that gaming device. In one embodiment, the bingo, keno, or lottery game is displayed to the player. In another embodiment, the bingo, keno or lottery game is not displayed to the player, but the results of the bingo, keno, or lottery game determine the predetermined game outcome value for the primary or secondary game.
In the various bingo embodiments, as each gaming device is enrolled in the bingo game, such as upon an appropriate wager or engaging an input device, the enrolled gaming device is provided or associated with a different bingo card. Each bingo card consists of a matrix or array of elements, wherein each element is designated with a separate indicia, such as a number. It should be appreciated that each different bingo card includes a different combination of elements. For example, if four bingo cards are provided to four enrolled gaming devices, the same element may be present on all four of the bingo cards while another element may solely be present on one of the bingo cards.
In operation of these embodiments, upon providing or associating a different bingo card with each of a plurality of enrolled gaming devices, the central controller randomly selects or draws, one at a time, a plurality of the elements. As each element is selected, a determination is made for each gaming device as to whether the selected element is present on the bingo card provided to that enrolled gaming device. This determination can be made by the central controller, the gaming device, a combination of the two, or in any other suitable manner. If the selected element is present on the bingo card provided to that enrolled gaming device, that selected element on the provided bingo card is marked or flagged. This process of selecting elements and marking any selected elements on the provided bingo cards continues until one or more predetermined patterns are marked on one or more of the provided bingo cards. It should be appreciated that in one embodiment, the gaming device requires the player to engage a daub button (not shown) to initiate the process of the gaming device marking or flagging any selected elements.
After one or more predetermined patterns are marked on one or more of the provided bingo cards, a game outcome is determined for each of the enrolled gaming devices based, at least in part, on the selected elements on the provided bingo cards. As described above, the game outcome determined for each gaming device enrolled in the bingo game is utilized by that gaming device to determine the predetermined game outcome provided to the player. For example, a first gaming device to have selected elements marked in a predetermined pattern is provided a first outcome of win $10 which will be provided to a first player regardless of how the first player plays in a first game, and a second gaming device to have selected elements marked in a different predetermined pattern is provided a second outcome of win $2 which will be provided to a second player regardless of how the second player plays a second game. It should be appreciated that as the process of marking selected elements continues until one or more predetermined patterns are marked, this embodiment ensures that at least one bingo card will win the bingo game and thus at least one enrolled gaming device will provide a predetermined winning game outcome to a player. It should be appreciated that other suitable methods for selecting or determining one or more predetermined game outcomes may be employed.
In one example of the above-described embodiment, the predetermined game outcome may be based on a supplemental award in addition to any award provided for winning the bingo game as described above. In this embodiment, if one or more elements are marked in supplemental patterns within a designated number of drawn elements, a supplemental or intermittent award or value associated with the marked supplemental pattern is provided to the player as part of the predetermined game outcome. For example, if the four corners of a bingo card are marked within the first twenty selected elements, a supplemental award of $10 is provided to the player as part of the predetermined game outcome. It should be appreciated that in this embodiment, the player of a gaming device may be provided a supplemental or intermittent award regardless of whether the enrolled gaming device's provided bingo card wins or does not win the bingo game as described above.
In another embodiment, one or more of the gaming devices are in communication with a central server or controller for monitoring purposes only. That is, each individual gaming device randomly generates the game outcomes to be provided to the player and the central server or controller monitors the activities and events occurring on the plurality of gaming devices. In one embodiment, the gaming network includes a real-time or on-line accounting and gaming information system operably coupled to the central server or controller. The accounting and gaming information system of this embodiment includes a player database for storing player profiles, a player tracking module for tracking players and a credit system for providing automated casino transactions.
In one embodiment, the gaming device disclosed herein is associated with or otherwise integrated with one or more player tracking systems. Player tracking systems enable gaming establishments to recognize the value of customer loyalty through identifying frequent customers and rewarding them for their patronage. In one embodiment, the gaming device and/or player tracking system tracks any player's gaming activity at the gaming device. In one such embodiment, the gaming device includes at least one card reader 38 in communication with the processor. In this embodiment, a player is issued a player identification card which has an encoded player identification number that uniquely identifies the player. When a player inserts their playing tracking card into the card reader to begin a gaming session, the card reader reads the player identification number off the player tracking card to identify the player. The gaming device and/or associated player tracking system timely tracks any suitable information or data relating to the identified player's gaming session. Directly or via the central controller, the gaming device processor communicates such information to the player tracking system. The gaming device and/or associated player tracking system also timely tracks when a player removes their player tracking card when concluding play for that gaming session. In another embodiment, rather than requiring a player to insert a player tracking card, the gaming device utilizes one or more portable devices carried by a player, such as a cell phone, a radio frequency identification tag or any other suitable wireless device to track when a player begins and ends a gaming session. In another embodiment, the gaming device utilizes any suitable biometric technology or ticket technology to track when a player begins and ends a gaming session.
During one or more gaming sessions, the gaming device and/or player tracking system tracks any suitable information or data, such as any amounts wagered, average wager amounts, and/or the time at which these wagers are placed. In different embodiments, for one or more players, the player tracking system includes the player's account number, the player's card number, the player's first name, the player's surname, the player's preferred name, the player's player tracking ranking, any promotion status associated with the players player tracking card, the player's address, the player's birthday, the player's anniversary, the player's recent gaming sessions, or any other suitable data. In one embodiment, such tracked information and/or any suitable feature associated with the player tracking system is displayed on a player tracking display 40. In another embodiment, such tracked information and/or any suitable feature associated with the player tracking system is displayed via one or more service windows (not shown) which are displayed on the central display device and/or the upper display device.
In one embodiment, a plurality of the gaming devices are capable of being connected together through a data network. In one embodiment, the data network is a local area network (LAN), in which one or more of the gaming devices are substantially proximate to each other and an on-site central server or controller as in, for example, a gaming establishment or a portion of a gaming establishment. In another embodiment, the data network is a wide area network (WAN) in which one or more of the gaming devices are in communication with at least one off-site central server or controller. In this embodiment, the plurality of gaming devices may be located in a different part of the gaming establishment or within a different gaming establishment than the off-site central server or controller. Thus, the WAN may include an off-site central server or controller and an off-site gaming device located within gaming establishments in the same geographic area, such as a city or state. The WAN gaming system may be substantially identical to the LAN gaming system described above, although the number of gaming devices in each system may vary relative to one another.
In another embodiment, the data network is an internet or intranet. In this embodiment, the operation of the gaming device can be viewed at the gaming device with at least one internet browser. In this embodiment, operation of the gaming device and accumulation of credits may be accomplished with only a connection to the central server or controller (the internet/intranet server) through a conventional phone or other data transmission line, digital subscriber line (DSL), T-1 line, coaxial cable, fiber optic cable, or other suitable connection. In this embodiment, players may access an internet game page from any location where an internet connection and computer or other internet facilitator is available. The expansion in the number of computers and number and speed of internet connections in recent years increases opportunities for players to play from an ever-increasing number of remote sites. It should be appreciated that the enhanced bandwidth of digital wireless communications may render such technology suitable for some or all communications, particularly if such communications are encrypted. Higher data transmission speeds may be useful for enhancing the sophistication and response of the display and interaction with the player.
As mentioned above, in one embodiment, the present disclosure may be employed in a server-based gaming system. In one such embodiment, as described above, one or more gaming devices are in communication with a central server or controller. The central server or controller may be any suitable server or computing device which includes at least one processor and a memory or storage device. In alternative embodiments, the central server is a progressive controller or another gaming machine in the gaming system. In one embodiment, the memory device of the central server stores different game programs and instructions, executable by a gaming device processor, to control the gaming device. Each executable game program represents a different game or type of game which may be played on one or more of the gaming devices in the gaming system. Such different games may include the same or substantially the same game play with different pay tables. In different embodiments, the executable game program is for a primary game, a secondary game or both. In another embodiment, the game program may be executable as a secondary game to be played simultaneous with the play of a primary game (which may be downloaded to or fixed on the gaming device) or vice versa.
In this embodiment, each gaming device at least includes one or more display devices and/or one or more input devices for interaction with a player. A local processor, such as the above-described gaming device processor or a processor of a local server, is operable with the display device(s) and/or the input device(s) of one or more of the gaming devices.
In operation, the central controller is operable to communicate one or more of the stored game programs to at least one local processor. In different embodiments, the stored game programs are communicated or delivered by embedding the communicated game program in a device or a component (e.g., a microchip to be inserted in a gaming device), writing the game program on a disc or other media, or downloading or streaming the game program over a dedicated data network, internet, or a telephone line. After the stored game programs are communicated from the central server, the local processor executes the communicated program to facilitate play of the communicated program by a player through the display device(s) and/or input device(s) of the gaming device. That is, when a game program is communicated to a local processor, the local processor changes the game or type of game played at the gaming device.
In another embodiment, a plurality of gaming devices at one or more gaming sites may be networked to the central server in a progressive configuration, as known in the art, wherein a portion of each wager to initiate a base or primary game may be allocated to one or more progressive awards. In one embodiment, a progressive gaming system host site computer is coupled to a plurality of the central servers at a variety of mutually remote gaming sites for providing a multi-site linked progressive automated gaming system. In one embodiment, a progressive gaming system host site computer may serve gaming devices distributed throughout a number of properties at different geographical locations including, for example, different locations within a city or different cities within a state.
In one embodiment, the progressive gaming system host site computer is maintained for the overall operation and control of the progressive gaming system. In this embodiment, a progressive gaming system host site computer oversees the entire progressive gaming system and is the master for computing all progressive jackpots. All participating gaming sites report to, and receive information from, the progressive gaming system host site computer. Each central server computer is responsible for all data communication between the gaming device hardware and software and the progressive gaming system host site computer. In one embodiment, an individual gaming machine may trigger a progressive award win. In another embodiment, a central server (or the progressive gaming system host site computer) determines when a progressive award win is triggered. In another embodiment, an individual gaming machine and a central controller (or progressive gaming system host site computer) work in conjunction with each other to determine when a progressive win is triggered, for example through an individual gaming machine meeting a predetermined requirement established by the central controller.
In one embodiment, a progressive award win is triggered based on one or more game play events, such as a symbol-driven trigger. In other embodiments, the progressive award triggering event or qualifying condition may be achieved by exceeding a certain amount of game play (such as number of games, number of credits, or amount of time), or reaching a specified number of points earned during game play. In another embodiment, a gaming device is randomly or apparently randomly selected to provide a player of that gaming device one or more progressive awards. In one such embodiment, the gaming device does not provide any apparent reasons to the player for winning a progressive award, wherein winning the progressive award is not triggered by an event in or based specifically on any of the plays of any primary game. That is, a player is provided a progressive award without any explanation or alternatively with simple explanations. In another embodiment, a player is provided a progressive award at least partially based on a game triggered or symbol triggered event, such as at least partially based on the play of a primary game.
In one embodiment, one or more of the progressive awards are each funded via a side bet or side wager. In this embodiment, a player must place or wager a side bet to be eligible to win the progressive award associated with the side bet. In one embodiment, the player must place the maximum bet and the side bet to be eligible to win one of the progressive awards. In another embodiment, if the player places or wagers the required side bet, the player may wager at any credit amount during the primary game (i.e., the player need not place the maximum bet and the side bet to be eligible to win one of the progressive awards). In one such embodiment, the greater the player's wager (in addition to the placed side bet), the greater the odds or probability that the player will win one of the progressive awards. It should be appreciated that one or more of the progressive awards may each be funded, at least in part, based on the wagers placed on the primary games of the gaming machines in the gaming system, via a gaming establishment or via any suitable manner.
In another embodiment, one or more of the progressive awards are partially funded via a side-bet or side-wager which the player may make (and which may be tracked via a side-bet meter). In one embodiment, one or more of the progressive awards are funded with only side-bets or side-wagers placed. In another embodiment, one or more of the progressive awards are funded based on players wagers as described above as well as any side-bets or side-wagers placed.
In one alternative embodiment, a minimum wager level is required for a gaming device to qualify to be selected to obtain one of the progressive awards. In one embodiment, this minimum wager level is the maximum wager level for the primary game in the gaming machine. In another embodiment, no minimum wager level is required for a gaming machine to qualify to be selected to obtain one of the progressive awards.
In another embodiment, a plurality of players at a plurality of linked gaming devices in a gaming system participate in a group gaming environment. In one embodiment, a plurality of players at a plurality of linked gaming devices work in conjunction with one another, such as by playing together as a team or group, to win one or more awards. In one such embodiment, any award won by the group is shared, either equally or based on any suitable criteria, amongst the different players of the group. In another embodiment, a plurality of players at a plurality of linked gaming devices compete against one another for one or more awards. In one such embodiment, a plurality of players at a plurality of linked gaming devices participate in a gaming tournament for one or more awards. In another embodiment, a plurality of players at a plurality of linked gaming devices play for one or more awards wherein an outcome generated by one gaming device affects the outcomes generated by one or more linked gaming devices.
The present disclosure may be implemented in various configurations for gaming machines, gaming devices, or gaming systems, including but not limited to: (1) a dedicated gaming machine, gaming device, or gaming system.
Gaming System Providing Stacks of Symbols Using Independent Reels
In one embodiment, the gaming system disclosed herein includes or displays a plurality of independent reels arranged as a matrix of independent reels. In one embodiment, each independent reel includes a plurality of symbols in a plurality of symbol positions, and is associated with a probability of generating each of the plurality of symbols. In one embodiment, each independent reel is associated with a virtual reel strip and/or a table which define a plurality of probabilities of generating the plurality of symbols. At least two adjacent independent reels (such as two independent reels positioned horizontally adjacent to one another) each utilize or are associated with a virtual reel strip and/or a table defining a relatively high probability of generating a same designated symbol. Due to the adjacent independent reels which are relatively likely to generate the designated symbol, the gaming system disclosed herein is configured to provide a game with a relatively high probability of generating one or more adjacent designated symbols for an initial generation of symbols and for one or more re-generations of symbols during a play of a game, thus causing a stacked symbol effect with respect to the designated symbol.
In one embodiment, the disclosed gaming system displays a plurality of independent reels, as indicated in block 102. In one such embodiment, the gaming system displays the plurality independent reels as a matrix of independent reels, such that each independent reel is adjacent to at least one other independent reel. In this embodiment, each independent reel includes a plurality of symbols, such that a spin of that independent reel results in a display of one of the plurality of symbols.
In one embodiment, each of the independent reels is associated with a virtual reel strip, as indicated by block 102. In one such embodiment, each virtual reel strip includes a plurality of symbols in a plurality of symbol positions, the symbols being displayable for a spin of the independent reel. In this embodiment, each symbol has a probability of being generated for a spin of the independent reel. In one embodiment, each virtual reel strip is associated with a table which defines the probabilities of generating the symbols of that independent reel. In various embodiments, for a spin of any of the independent reels, the disclosed gaming system selects one of the symbols for the independent reel to display in accordance with the defined probabilities.
In one embodiment, at least two adjacent independent reels each have virtual reel strips associated with a table of symbols having a relatively high probability of generating a designated symbol, as indicated by block 102. In one embodiment, such independent reels (i.e., independent reels which are relatively likely to generate the designated symbol) are referred to as weighted independent reels with respect to the designated symbol. In one such embodiment, the adjacent weighted independent reels are horizontally adjacent to one another. In another embodiment, the adjacent weighted independent reels are vertically adjacent to one another. In various embodiments, the gaming system provides more than two adjacent weighted independent reels. In one embodiment, the gaming system provides a cluster or dump of weighted independent reels, such that two or more weighted independent reels are horizontally adjacent to each other and two or more weighted independent reels are vertically adjacent to each other.
In one embodiment, the disclosed gaming system enables a player to wager on a play of the game including the plurality of independent reels, as indicated by block 104. In one embodiment, for the play of the game, the gaming system generates a symbol for each of the plurality of independent reels, as indicated by block 106. In one such embodiment, the gaming system generates the plurality of symbols by selecting one of the numbers associated with one of the symbols of the table, such as based on an output of a random number generator, and by displaying the appropriate symbol of the virtual reel strip. In another embodiment, each of the independent reels is a mechanical reel, and the gaming system generates a symbol for each of the independent reels by spinning that mechanical reel. It should be appreciated that the instant disclosure contemplates any suitable method of determining a random symbol for display by an independent reel based on a probability associated with that symbol.
In one embodiment, the gaming system determines whether any winning symbol combinations are generated for the play of the game, as indicated by block 108. It should be appreciated that in various embodiments, by displaying at least two adjacent independent reels which are weighted toward generating the designated symbol, the disclosed gaming system increases the probability of generating winning symbol combinations for plays of the game. In one embodiment, if no winning symbol combination is generated, the gaming system ends the play of the game and enables the player to wager again on a play of the game, as indicated by block 104.
In one embodiment, if at least one winning symbol combination is generated, the gaming system provides an award based on any generated winning symbol combinations, as indicated by block 110. In this embodiment, the gaming system determines at least one independent reel for which to re-generate a symbol for the play of the game, as indicated by block 112. In one such embodiment, the at least one determined independent reel is an independent reel displaying a symbol included in a winning symbol combination, as indicated by block 112.
In one embodiment, the gaming system re-generates a symbol for display by any determined independent reels, as indicated by block 114. Specifically, the gaming system in one embodiment displays a symbol for that independent reel which is in a symbol position of the associated virtual reel strip adjacent to the symbol position of the currently displayed symbol of the associated virtual reel strip. It should be appreciated that if the currently displayed symbol is a designated symbol, the gaming system is relatively likely to re-generate and display another designated symbol due to the plurality of adjacent (i.e., stacked) designated symbols of one or more of the independent reels disclosed herein.
In one embodiment, based on any re-generated symbols, the gaming system determines whether any new winning symbol combinations are displayed, as indicated in block 108. If any new winning symbol combinations are displayed, the gaming system provides an award as indicated by block 110 and re-generates one or more symbols for one or more independent reels, as indicated by blocks 112 and 114. In one embodiment, if the gaming system determines that no additional winning symbol combinations are generated, as indicated by block 108, the gaming system ends the play of the game and enables the player to wager on a new play of the game, as indicated by block 104.
In an alternative embodiment, the gaming system disclosed herein does not re-generate any symbols for a play of the game. In this embodiment, upon providing the determined award based on any winning symbol combinations, as indicated by block 110, the gaming system ends the play of the game. In another embodiment, the gaming system performs at least one re-generation of symbols for a play of the game, up to a maximum number of regenerations. That is, the gaming system performs the loop indicated by block 108, 110, 112, and 114 a plurality of times up to a maximum number of times. In various such embodiments, the maximum number of regenerations is predetermined, randomly determined, determined based on a generated symbol or symbol combination, determined based on a quantity of designated symbols of the independent reel, determined based on a random determination by the central controller, determined based on a random determination at the gaming system, determined based on one or more side wagers placed, determined based on the players primary game wager, determined based on time (such as the time of day), determined based on an amount of coin-in accumulated in one or more pools, or determined based on any other suitable method or criteria.
In the illustrated embodiment, for a generation of a symbol for an independent reel, the gaming system selects one of the symbols from either Table A 400 or Table B 450 by randomly selecting one of the numbers of the number column 420 or 470, respectively, and displaying the symbol associated with the selected number. In this embodiment, the gaming system has an equal probability of selecting each of the numbers one through twenty of number columns 420 and 470. It should therefore be appreciated that the symbols in symbol columns 410 and 460 define probabilities of selecting each symbol for a spin of a reel associated with either Table A 400 or Table B 450. Specifically, since sixteen of the twenty symbols of Table A 400 are King symbols 410b, a random selection of one of the numbers of the number column 420 results in an 80% chance of generating a King symbol. A spin of an independent reel associated with Table A 400 has a 5% chance of generating each of an Ace symbol 410a, a Queen Symbol 410c, a Jack symbol 410d, and a Ten Symbol 410e (i.e., each symbol is included once out of twenty total symbols). Since each symbol of Table B 450 is repeated four times, the probability of generating an Ace symbol 460a, a King symbol 460b, a Queen symbol 460c, a Jack symbol 460d, and a Ten symbol 460e is each 20%. It should therefore be appreciated that Table A 400 represents a weighted table with respect to the King symbol, and that Table B 450 represents a non-weighted table.
In one embodiment, each of the independent reels of the disclosed gaming system includes a virtual reel strip associated with one of the tables 400 or 450. In this embodiment, the order of symbols of the tables 400 or 450 define the order of symbols of the virtual reel strip. Thus, in the illustrated embodiment, a virtual reel strip associated with Table A 400 includes fifteen King symbols in adjacent symbol positions of the virtual reel strip. In this embodiment, displaying a plurality of symbols sequentially according to the order of symbols of the reel strips is relatively likely to result in a plurality of the King symbols being displayed sequentially for the independent reel associated with Table A 400. In various embodiments, the quantity of adjacent designated symbols (such as King symbols) is less than fifteen designated symbols, such as approximately five designated symbols.
In the illustrated schematic representation 500, any independent reel which uses Table A 400 to generate symbols for spins of that independent reel is weighted with respect to the King symbol 410b. It should be appreciated that in the schematic representation 500 of
In one embodiment, each of the independent reels 502a, 502b, 502c, 502d, 502e, 502f, and 5029 provides a stacked symbol effect with respect to subsequent generations of symbols during the play of the game. In this embodiment, the gaming system is configured to determine one or more independent reels for a play of the game in which to regenerate a symbol. The gaming system regenerates such symbols by displaying a symbol from a symbol position of a virtual reel strip which is adjacent to the symbol position of the displayed symbol. Thus, it should be appreciated that if one of the designated symbols from the stack of designated symbols is initially displayed, the gaming system is relatively likely to display another one of the stacked symbols for the re-generation. When implemented as a cascading symbols game with respect to the individual independent reels, it should be appreciated that each of the independent reels 502a, 502b, 502c, 502d, 502e, 502f, and 502g provides a stacked symbol effect.
Specifically,
The gaming device of the embodiment illustrated in
At the point in time illustrated by
It should be appreciated that winning symbol combination 610b was generated and displayed for a plurality of independent reels providing a stacked symbol effect with respect to the King symbol. Specifically, winning symbol combination 610b includes three King symbols each of which was generated by an independent reel which has an 80% chance of generating a King symbol. It should thus be appreciated that by providing the plurality of weighted independent reels, the disclosed gaming system advantageously provides a stacked symbol effect with respect to the King symbol, resulting in a relatively high probability of generating winning symbol combinations, such as winning symbol combination 610b, for an initial generation of symbols during a play of the game.
It should be appreciated that in the illustrated embodiment, each of the independent reels which re-generates a symbol is an independent reel which utilizes weighted Table A 400. It should be further appreciated that since each independent reel which is being re-spun is associated with weighted Table A 400, the gaming device 10a provides the player with a relatively high probability of re-generating a King symbol for the additional spins of the independent reels. In another embodiment, the gaming device re-spins one or more independent reels which do not utilize weighted tables, such as independent reels associated with Table B 450.
In other embodiments, such as the embodiment discussed above with respect to
It should be appreciated that by re-generating symbols adjacent to previously displayed symbols on the virtual reel strips associated with the disclosed stacked independent reels, the disclosed gaming system provides players with additional opportunities to win awards for winning symbol combinations generated during the play of a game without removing valuable symbols (such as designated symbols for which a stacked symbol effect is provided) from the viewable area of the game. Specifically, in traditional stacked symbol games, a shifting or re-generating feature would frequently result in one or more of the plurality of stacked symbols being shifted out of the viewable area of the disclosed game. By re-generating one or more symbols using the independent reels as disclosed herein (and continuing to display other previously-generated symbols), the disclosed system provides a cascading or tumbling symbols game while maintaining the benefits of the stacked symbol effect of implemented by the independent reels.
It should be appreciated that since each of the independent reels 602c, 602g, and 602k utilizes weighted Table A 400, the gaming device 10a is relatively likely to re-generate at least one King symbol. Moreover, it should be appreciated that the gaming device 10a is relatively unlikely to generate the Jack symbol by spinning independent reel 602g. It should be therefore appreciated that symbols are re-generated using weighted independent reels 602c, 602g, and 602k in accordance with a relatively high probability of re-generating at least one additional winning symbol combination for the play of the game.
In the embodiment illustrated in
In the embodiment illustrated in
In the illustrated embodiment, the gaming system disclosed herein is configured to utilize the dependent reel 710 to determine which of a plurality of independent reels to use to generate symbols for a play of a game having a matrix of independent reels. In one embodiment, the matrix of independent reels includes five columns or windows of independent reels, each column or window including three independent reels. In the illustrated embodiment, the gaming system spins dependent reel 710 to determine which independent reels to use to generate symbols for at least one of the five columns of independent reels. In the illustrated embodiment, the gaming system determines that three adjacent independent reels 702b, 702c, and 702d will be used to generate symbols for one of the columns during a play of the game. This determination is indicated by the independent reels selection indicator 720.
In one embodiment, for a play of the game, the gaming system generates a symbol utilizing each of the independent reels 702b, 702c, and 702d selected by spinning the dependent reel 710. These generations are based on the tables 400 and 450 associated with the independent reels, such that the gaming system is relatively likely to generate a designated symbol for the top independent reel (i.e., independent reel 702b). Thus, it should be appreciated that the dependent reel 710 in one embodiment increases player excitement and enjoyment by changing which independent reels (and the tables associated with the independent reels) are utilized to generate symbols for a play of the game.
In one embodiment, during a play of the game, the gaming system re-generates a set of independent reels usable to generate symbols by re-spinning dependent reel 710. In one such embodiment, the gaming system turns or shifts the independent reel 710 by one position upon determining that a winning symbol combination has been displayed, such that a different set of independent reels are utilized to generate symbols for the play of the game. In another embodiment, the gaming system spins dependent reel 710 during the play of the game to newly generate a subset of independent reels usable to generate symbols.
It should be appreciated that in one embodiment, such as the embodiment illustrated in
In one embodiment, the dependent reel and the plurality of independent reels contained thereon are implemented as mechanical reels. In this embodiment, the dependent reel is an outer mechanical reel, and each symbol position of the outer mechanical reel includes an inner mechanical independent reel. For the play of the game, the gaming system spins the outer mechanical reel to generate a subset of the inner independent reels, and spins each of the subset of independent reels to generate symbols usable to determine awards.
In one embodiment, the gaming system displays the spinning of the dependent reel to the player. In another embodiment, the gaming system selects a plurality of independent reels from the symbol positions of the dependent reel without displaying the selection to the player. In one embodiment, the gaming system displays an indicator corresponding to which of the independent reels is being used to generate symbols for the play of the game. For example, the gaming system displays a green ring around any independent reel utilizing Table A 400 (i.e., the table which is relatively likely to generate the designated symbol) and a red ring around any independent reel utilizing Table B 450 (i.e., the table which is not weighted toward generating the designated symbol). Moreover, in one embodiment the gaming system indicates the shifting or rotating of the dependent reel 710 such that when a portion of a stack of independent reels is displayed, the player is aware that the currently displayed independent reels are relatively likely to generate designated symbols (and thus additional winning symbol combinations). It should be appreciated that indicating which of the independent reels is being utilized to generate symbols for a play of the game increases player excitement and enjoyment by magnifying the stacked symbol effect with respect to the designated symbol for a play of the game.
In one embodiment, the gaming system disclosed herein is configured to assign the plurality of reel strips and tables to the plurality of independent reels prior to a player wagering on a play of the game. In this embodiment, the disclosed gaming system provides a same stacked symbol effect for a plurality of plays of the game for a plurality of different players. In another embodiment, the gaming system assigns the reel strips and tables to the independent reels after the player has wagered on a play of the game. In one such embodiment, the gaming system assigns at least one table to at least one reel based on the players wager on the play of the game. In various embodiments, which reel strips are assigned to which independent reels is predetermined, randomly determined, determined based on a generated symbol or symbol combination, determined based on a random determination by the central controller, determined based on a random determination at the gaming system, determined based on one or more side wagers placed, determined based on time (such as the time of day), determined based on an amount of coin-in accumulated in one or more pools or determined based on any other suitable method or criteria. In one embodiment, the gaming system determines a plurality of adjacent weighted independent reels prior to a play of the game and randomly determines which of a plurality of weighted tables to assign to the remainder of the reels. It should be appreciated that any suitable mechanism of determining which tables to assign to which reel is contemplated herein.
In one embodiment, the gaming system selects an independent reel with which to re-generate a symbol for a play of the game based on the winning symbol combinations generated, such as by re-generating a symbol for each independent reel which displays a symbol included in a winning symbol combination. In other embodiments, which independent reel is selected to re-generate a symbol is predetermined, randomly determined, determined based on a generated symbol or symbol combination, determined based on a random determination by the central controller, determined based on a random determination at the gaming system, determined based on one or more side wagers placed, determined based on the player's primary game wager, determined based on time (such as the time of day), determined based on an amount of coin-in accumulated in one or more pools or determined based on any other suitable method or criteria.
In one embodiment, each table utilized by the independent reels of the disclosed gaming system includes the same plurality of symbols. In another embodiment, at least one table includes at least one symbol which is not included on at least one different table. It should be appreciated that in this embodiment, certain of the independent reels associated with certain of the tables are incapable of generating certain symbols for the play of the game. In one embodiment, each independent reel is associated with a table which includes the designated symbol (i.e., a symbol for which a stacked symbol effect is provided) based on a non-zero probability.
In one embodiment, wherein each independent reel utilizes a reel strip including the same set of symbols, the disclosed gaming system is configured to shift at least one previously displayed symbol such that a different independent reel displays the shifted symbol. In various embodiments, the gaming system shifts a symbol by displaying the symbol using a shifted-to independent reel. In one embodiment, the gaming system shifts the symbol from an adjacent independent reel to the different independent reel. In a further embodiment, the gaming system shifts a symbol from an independent reel which utilizes a weighted reel strip to generate symbols to a different independent reel which does not utilize a weighted reel strip. In various embodiments, which symbol to shift to a different independent reel is predetermined, randomly determined, determined based on a generated symbol or symbol combination, determined based on a random determination by the central controller, determined based on a random determination at the gaming system, determined based on one or more side wagers placed, determined based on the player's primary game wager, determined based on time (such as the time of day), determined based on an amount of coin-in accumulated in one or more pools or determined based on any other suitable method or criteria.
In one embodiment, the gaming system disclosed herein is programmed to randomly re-generate a symbol for an independent reel as opposed to displaying a symbol in an adjacent symbol position to the currently displayed symbol. In this embodiment, for any determined independent reel during a play of the game, the gaming system randomly generates a symbol using the associated reel strip and displays the generated symbol to the player. In various embodiments, whether to randomly generate a symbol for a determined independent reel is predetermined, randomly determined, determined based on a generated symbol or symbol combination, determined based on a random determination by the central controller, determined based on a random determination at the gaming system, determined based on one or more side wagers placed, determined based on the player's primary game wager, determined based on time (such as the time of day), determined based on an amount of coin-in accumulated in one or more pools or determined based on any other suitable method or criteria.
In one embodiment, the gaming system alters the table utilized by a determined one of the independent reels prior to re-generating a symbol for that independent reel. In one such embodiment, the gaming system randomly selects one of a plurality of tables and associates the selected table with an independent reel determined to re-generate a symbol prior re-generating a symbol for that independent reel. In another embodiment, the gaming system shifts the table associated with an adjacent independent reel to the determined independent reel prior to spinning the independent reel. In various embodiments, the reel strip with which the gaming system associates the determined independent reel is predetermined, randomly determined, determined based on a generated symbol or symbol combination, determined based on a random determination by the central controller, determined based on a random determination at the gaming system, determined based on one or more side wagers placed, determined based on the player's primary game wager, determined based on time (such as the time of day), determined based on an amount of coin-in accumulated in one or more pools or determined based on any other suitable method or criteria.
In one embodiment, the gaming system disclosed herein is configured to provide at least two adjacent independent reels associated with weighted reel strips for generating a designated symbol, thus causing a stacking effect with respect to the designated symbol. In one embodiment, the designated symbol is a wild symbol, usable as any symbol for purposes of determining winning symbol combinations. In another embodiment, the designated symbol is a symbol usable to form designated winning symbol combinations, such as winning symbol combinations associated with high-value awards. In various embodiments, the gaming system is programmed to adjacently position independent reels associated with reel strips weighted for other symbols, such as symbols which are randomly determined for a play of the game. In various embodiments, which symbols are stacked is predetermined, randomly determined, determined based on a generated symbol or symbol combination, determined based on a random determination by the central controller, determined based on a random determination at the gaming system, determined based on one or more side wagers placed, determined based on the player's primary game wager, determined based on time (such as the time of day), determined based on an amount of coin-in accumulated in one or more pools or determined based on any other suitable method or criteria.
It should be understood that various changes and modifications to the presently preferred embodiments described herein will be apparent to those skilled in the art. Such changes and modifications can be made without departing from the spirit and scope of the present subject matter and without diminishing its intended advantages. It is therefore intended that such changes and modifications be covered by the appended claims.
