To play a conventional slot machine, a player deposits money in the form of coins, gaming tokens or paper currency either into a coin head or bill acceptor. The coins and gaming tokens are collected in a reservoir inside the gaming machine while the paper currency is collected in the bill acceptor inside the gaming machine. If the coins, gaming tokens or paper currency are validated as authentic, the player accrues the appropriate number of playing credits on a credit meter. For example, a twenty-five cent gaming machine will accrue four credits for each dollar deposited into the gaming machine.
After accruing credits on the credit meter, the player determines how many credits to wager on the next spin of the slot reels. The gaming device or player then spins the reels by pressing the spin button or by pulling a handle. When the reels stop spinning, symbols are displayed and the player collects credits for winning combinations of symbols on the reels, if any, according to a pay table.
Specifically, slot machines include a symbol matrix which includes symbols displayed on three or more of the reels (also called “columns” or “reel columns”) that are adjacent to each other. The resulting matrix of symbols typically ranges from three columns by three rows with nine total symbols, to five columns by three rows with fifteen total symbols. Each position in the symbol matrix is referenced by column, from left to right, and row, from the top to bottom (“symbol positions”). For example: symbol position 1/2 is located in column 1 and row 2.
Players collect credits for predetermined winning symbol combinations that appear in specific or designated symbol positions (i.e, “pay lines”) on the reels. Winning symbol combinations typically require that three or more of the same symbols appear adjacent to each other starting from the leftmost position of a pay line (i.e., a “line pay”). In addition, players may also collect credits for winning symbol combinations that appear anywhere on a pay line (i.e., a “line scatter pay”) or anywhere on the reels (i.e., a “reel scatter pay”).
Credits are awarded to the player for each winning symbol combination based on a predetermined schedule or paytable. For line pays and line scatter pays, the number of credits wagered on the winning pay line multiplies the number of credits indicated by the pay table. For reel scatter pays, the total number of credits wagered multiplies the number of credits indicated by the pay table.
Following any type of win or payout (e.g., line pays, line scatter pays or reel scatter pays), a designated number of credits are added or transferred to the player's credit balance shown on the credit meter. As long as the player has credits on the credit meter, the player may continue to play the game.
Accordingly, there is a continuing need for new gaming devices which provide players with more opportunities to obtain awards in a game.
The present invention relates generally to a slot game and payout methods for a slot machine and more particularly, to a game and a payout method based upon multiple symbols in one or more symbol positions of the symbol matrix on a set of reels.
In one embodiment, the gaming device includes a game having a plurality of reels including a plurality of symbol positions or locations on the reels. The symbol positions or locations are positions or areas on the reels where the symbols are displayed to a player. Typically, in conventional gaming devices, a reel-type game includes a plurality of reels having symbols where one symbol is displayed in each symbol position on the reels. The present invention includes at least one and preferably, a plurality of symbols having at least one replicator or split symbol. The replicator symbol displays at least two of the same or identical symbols in a single symbol position on the reels. For example, when a replicator symbol is indicated in a symbol position on the reels, the replicator symbol may display two identical symbols, three identical symbols or any suitable number of identical symbols desired by the game implementor in a single symbol position. Therefore, contrary to conventional reel-type games, the replicator symbol of the present invention enables the gaming device to display more symbols on the reels and thereby enhances the probability that a winning combination of symbols will occur on the reels. This increases the player's excitement and enjoyment of the game because the player has a better opportunity to obtain a winning combination of symbols and thereby a better opportunity to obtain an award in the game.
In one embodiment, a winning symbol combination includes symbols indicated in at least one symbol position on a payline associated with the reels. In another embodiment, a winning symbol combination includes symbols indicated in at least one symbol position on a plurality of paylines associated with the reels. In a further embodiment, a winning symbol combination includes symbols indicated in at least one symbol position on any of the paylines associated with the reels. It should be appreciated that a winning symbol combination may be indicated in any symbol position or symbol positions on the reels.
In one embodiment, the present invention includes replicator symbols that display at least two identical symbols to a player in any single symbol position on the reels. In another embodiment, the replicator symbol or replicator symbols are only indicated in a designated symbol position or symbol positions on the reels. It should be appreciated that the replicator symbol or replicator symbols may be indicated in one, a plurality or all of the symbol positions on the reels. It should also be appreciated that the replicator symbols may display the same or identical symbols or at least one different symbol in a symbol position on the reels.
In another embodiment, the symbols include at least one bonus symbol. The gaming device provides a bonus outcome to the player for a winning combination of bonus symbols where the winning combination includes at least two bonus symbols indicated in at least one symbol position on the reels. In another embodiment, the winning symbol combination including the bonus symbols is indicated in at least one symbol position on a payline associated with the reels. In a further embodiment, the winning symbol combination including the bonus symbol is indicated in at least one symbol position on a plurality of paylines associated with the reels. The bonus outcome may be at least one award, value, modifier such as a multiplier, free game, free spin, game element or any suitable award or outcome.
It is therefore an advantage of the present invention to provide a gaming device that increases the probability of obtaining awards in a game.
Another advantage of the present invention is to provide a gaming device that increases the probability of obtaining a relatively large award in a game.
Other objects, features and advantages of the invention will be apparent from the following detailed disclosure, taken in conjunction with the accompanying sheets of drawings, wherein like numerals refer to like parts, elements, components, steps and processes.
Referring now to the drawings, two alternative embodiments of the gaming device of the present invention are illustrated in

In one embodiment, as illustrated in
In one embodiment, part or all of the program code and/or operating data described above can be stored in a detachable or removable memory device, including, but not limited to, a suitable cartridge, disk or CD ROM. A player can use such a removable memory device in a desktop, a laptop personal computer, a personal digital assistant (PDA) or other computerized platform. The processor and memory device may be collectively referred to herein as a “computer” or “controller.”
In one embodiment, as discussed in more detail below, the gaming device randomly generates awards and/or other game outcomes based on probability data. That is, each award or other game outcome is associated with a probability and the gaming device generates the award or other game outcome to be provided to the player based on the associated probabilities. In this embodiment, since the gaming device generates outcomes randomly or based upon a probability calculation, there is no certainty that the gaming device will ever provide the player with any specific award or other game outcome.
In another embodiment, as discussed in more detail below, the gaming device employs a predetermined or finite set or pool of awards or other game outcomes. In this embodiment, as each award or other game outcome is provided to the player, the gaming device removes the provided award or other game outcome from the predetermined set or pool. Once removed from the set or pool, the specific provided award or other game outcome cannot be provided to the player again. This type of gaming device provides players with all of the available awards or other game outcomes over the course of the play cycle and guarantees the amount of actual wins and losses.
In one embodiment, as illustrated in

In one embodiment, one input device is a cash out button 38. 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, the player receives the coins or tokens in a coin payout tray 40. In one embodiment, when the player cashes out, the player may receive other payout mechanisms such as tickets or credit slips redeemable by a cashier or funding to the player's electronically recordable identification card.
In one embodiment, as mentioned above and 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, an SCSI port or a key pad.
In one embodiment, as seen in
In one embodiment, the gaming machine may include a player or other 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 either an analog, digital or other suitable format. The display devices may be configured to display the image acquired by the camera as well as 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 that image can be incorporated into the primary and/or secondary game as a game image, symbol or indicia.
Gaming device 10 can incorporate any suitable wagering primary or base game. The gaming machine or device of the present invention 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, number game or other game of chance susceptible to representation in an electronic or electromechanical form which produces a random outcome based on probability data upon activation from 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 into the present invention.
In one embodiment, as illustrated in
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 poker and initially deals five cards all face up from a virtual deck of fifty-two card deck. Cards may be dealt as in a traditional game of cards or in the case of the gaming device, may also include that the cards are 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 device, such as 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 replacement cards are dealt from the remaining cards in the deck. This results in a final five-card hand. The final five-card hand is compared to a payout table which utilizes conventional poker hand rankings to determine the winning hands. The player is provided with an award based on a winning hand and the 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 player is dealt 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 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 and preferable a plurality of the selectable indicia or numbers via an input device or via the touch screen. The gaming device then displays a series of drawn numbers to determine an amount of matches, if any, between the player's 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.
In one embodiment, in addition to winning credits 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 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 gaming device includes a program which will automatically begin a bonus round when the player has achieved a triggering event or qualifying condition in 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 one embodiment, once 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 geometric increase in the number of bonus wagering credits awarded. In one embodiment, extra bonus wagering credits may be redeemed 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 need be employed. That is, a player may not purchase an entry into a bonus game; he must win or earn entry through play of the primary game and, thus, play of the primary game is encouraged. In another embodiment, qualification of the bonus or secondary game could be accomplished through a simple “buy in” by the player if, for example, the player has been unsuccessful at qualifying through other specified activities.
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 of the present invention. 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 a 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, one or more of the gaming devices of the present invention 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.
A plurality of the gaming devices of the present invention 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 of the present invention may be substantially identical to the LAN gaming system described above, although the number of gaming devices in each system may vary relative to each other.
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 signal 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 are 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 enhanced bandwidth of digital wireless communications may render such technology suitable for some or all communications according to the present invention, 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.
In another embodiment, a plurality of gaming devices at one or more gaming sites may be networked to a 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 bonus or secondary event awards. In one embodiment, a 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 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 host site computer is maintained for the overall operation and control of the system. In this embodiment, a 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 host site computer. Each central server computer is responsible for all data communication between the gaming device hardware and software and the host site computer.
The present invention is directed to a gaming device having a game including a plurality of reels, wherein the reels include one or more split symbols or replicator symbols that display at least two identical symbols at a single symbol position on the reels. The replicator symbols increase the likelihood that a winning combination of symbols occurs on the reels. Therefore, a player's excitement and enjoyment of the game increases because the player believes that they have a better opportunity to obtain a winning symbol combination and thereby an award in the game.
Referring now to
In one embodiment, the symbols 100 include at least one split symbol or replicator symbol 102 or 104. Each replicator symbol includes at least two symbols from the plurality of symbols at a single symbol position on the reels. For example, replicator symbol 102 includes two “C” symbols in one symbol position (4/3) on reel 54d. Similarly, replicator symbol 104 includes three “F” symbols at a single symbol position (2/3) on reel 54b. In this embodiment, each replicator symbol includes at least two of the same symbols or identical symbols at a single symbol position. In another embodiment, the replicator symbols include at least two symbols from the plurality of symbols where at least one of the symbols associated with the replicator symbol is different. The replicator symbols provide additional symbols on the reels and therefore enhance the probability that a winning symbol combination or combinations will occur on the reels. In one embodiment, the gaming device provides an outcome such as one or more awards, prizes, credits, free spins, free games, game elements or any other suitable award to a player when a designated symbol combination including at least two of the symbols is indicated in at least one of the symbol positions on the reels 54.
In one embodiment a plurality of paylines such as paylines 52a, 52b and 52c are associated with the reels 54. In one embodiment, the gaming device provides an outcome to the player when a designated combination of symbols such as a winning combination of symbols is indicated in at least one symbol position on one of the paylines 52a, 52b or 52c. In another embodiment, the gaming device provides the outcome to the player when the winning symbol combination is indicated in at least one symbol position on a plurality of the paylines. In a further embodiment, the gaming device provides the outcome to the player when a winning symbol combination is indicated in at least one symbol position on any of the paylines associated with the reels. It should be appreciated that a designated combination of symbols or a winning symbol combination may be a line pay, a line scatter pay, a reel scatter pay or any suitable winning combination of the symbols.
In one embodiment, the gaming device includes a set of meters or displays used to display the salient information for the game, including the number of credits, number of pay lines, amount bet per line, total bet, and the amount paid to the player in a spin of the reels. If necessary, any number of meters may be added to further facilitate control of the games.
In one embodiment, the number of credits in the credit pool is displayed by a credit meter or credit display 114. The pool of credits increases and decreases according to the player's wins or losses in a game and may be supplemented, if necessary, by the player when the player deposits additional coins, tokens or paper currency into the gaming device.
In one embodiment, the number of pay lines upon which the player wagered in a game is displayed on a Number of Pay Lines meter or display 106. The pay lines are activated in a predetermined order, as follows: the first wager is applied to pay line 52a; the second wager is applied to pay line 52b; and the third wager is applied to pay line 52c. However, the games may have fewer or greater than three pay lines and activate the paylines in any suitable order.
In one embodiment, the number of credits wagered on each pay line is displayed on a Bet Per Line display. In this embodiment, the same amount is wagered on each of the pay lines. Alternatively, In another embodiment the player could wager different amounts on each pay line in a game.
In one embodiment, the total number of credits bet on all of the pay lines is displayed by a Total Bet display 110. The total bet is calculated by multiplying the number of pay lines by the bet per line. In addition, the number of credits awarded for any winning symbol combinations is displayed by a Paid display 112.
In one embodiment, all winning combinations are defined by pay tables or award summary tables associated with a game. The pay tables define the winning symbol combinations for a game such as a winning symbol combination including three or more of the same symbols on a pay line. Each symbol in a symbol position counts towards the total number of symbols on a pay line. In addition, a pay table may also define scatter awards for winning symbol combinations including symbols scattered anywhere on the reels. Alternatively, any pre-determined or designated arrangement of symbols may be defined as a winning symbol combination in a game and any suitable number of awards or credits may be provided to a player for the winning symbol combinations.
Referring now to
In this embodiment, the player must obtain a designated combination of the symbols 100 on at least one of the paylines 52a, 52b or 52c. Furthermore, in this example, the winning symbol combinations must form a line pay or a combination of at least three of the same symbols indicated in an least one of the symbol positions on reel 54a. For example, if one of the symbol positions on reel 54a includes a replicator symbol 102 or 104 and one of the symbol positions on reel 54b, on the same payline as the replicator symbol, includes the same symbol as the symbols of the replicator symbol, the player obtains a winning symbol combination including three of the same symbols on that payline. However, if the three identical or matching symbols are indicated in adjacent symbol positions on payline 52a associated with reels 54b and 54c but not reel 54a, the player does not obtain a winning symbol combination. Additionally in this example, the gaming device displays several different meters or displays as described above.

In the example, the winning symbol combination including the three E symbols indicated on payline 54b is formed by a single E symbol at symbol position 1/1, a single E symbol at symbol position 2/1 and a single E symbol at symbol position 3/1. The winning symbol combination including six D symbols is formed by a replicator symbol including two D symbols at symbol position 1/2, a replicator symbol including two D symbols at symbol position 2/2 and a replicator symbol including two D symbols at symbol position 3/2. Therefore, the two different winning symbol combinations show how the replicator symbols may provide more winning symbol combinations and thereby more awards in a game and also how these replicator symbols may provide larger awards in the game.
