Description

BACKGROUND

1. Field of the Invention

Embodiments of the present invention generally relate to a gaming device having wild symbol generation within a play matrix. More specifically, embodiments of the present invention relate to a slot machine having a variety of methods of play to enable wild symbols to be created in the play matrix.

2. Description of Related Art

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 he wishes to wager on the next spin of the slot reels. After setting the wager, the player spins the reels by pressing the spin button or by pulling a handle. When the reels stop spinning, symbols are displayed on the slot reels. The player then collects credits for winning combinations, if any, according to a pay table. More specifically, the slot machine operates as follows:

Symbol Matrix.

Slot symbols are displayed on 3 or more slot reels (also called “columns”) placed adjacent to each other. Each column contains at least 3 rows, with a symbol in each row. The resulting matrix of symbols typically ranges from 3 columns by 3 rows with 9 total symbols to 5 columns by 3 rows with 15 total symbols. Within the symbol matrix, positions on the slot reels may be referred to according to 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 (i.e., left-most column) and row 2 (i.e., middle row).

Winning Combinations.

Players collect credits for predetermined winning symbol combinations that appear in specific positions (“pay lines”) on the slot reels. Winning 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 (“line pays”). For example: a player may collect a line pay if 3 Banana symbols appeared in symbol positions 1/1, 2/1, 3/1 on a pay line using symbol positions 1/1, 2/1, 3/1, 4/1, and 5/1.

Players may also collect credits for predetermined winning combinations that appear anywhere on a pay line (“line scatter pays”) or anywhere on the slot reels (“reel scatter pays”). For example, a player may collect a line scatter pay if 3 Banana symbols appeared in symbol positions 1/1, 3/1, 5/1 on a pay line using symbol positions 1/1, 2/1, 3/1, 4/1, and 5/1; and collect a reel scatter pay if 3 Banana symbols appeared anywhere on the slot reels.

Pay Table.

Credits are awarded to the player for each winning symbol combination based on a predetermined schedule. 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 example, a player may wager two credits each on five pay lines, spin the reels, and collect twice the amount indicated on the pay table for a line pay or line scatter pay appearing on any of the five played pay lines. For reel scatter pays, the total number of credits wagered multiplies the number of credits indicated by the pay table. For example, a player may wager ten total credits, spin the reels, and collect ten times the amount indicated on the pay table for a reel scatter pay appearing on anywhere on the slot reels.

Following any type of pay (e.g., line pays, line scatter pays, or reel scatter pays), credits won are added 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. Following any spin, the player may collect the credit balance by pressing the Cash Out button.

While the above elements are common to many slot machine games, without more, players are often easily bored by simple conventional game play. Therefore, there is a need for a gaming apparatus having an improved game play to attract more players.

Embodiments of the present invention generally relate to a gaming device having wild symbol generation within a play matrix. More specifically, embodiments of the present invention relate to a slot machine having a variety of methods of play to enable wild symbols to be created in the play matrix.

Two alternative embodiments of the gaming device of the present invention are illustrated in FIGS. 1A and 1B as gaming device 10a and gaming device 10b, respectively. Gaming device 10a and/or gaming device 10b are generally referred to herein as gaming device 10.

In one embodiment, as illustrated in FIGS. 1A and 1B, gaming device 10 has a support structure, housing or cabinet which provides support for a plurality of displays, inputs, controls and other features of a conventional gaming machine. It is configured so that a player can operate it while standing or sitting. The gaming device may be positioned on a base or stand or can be configured as a pub-style table-top game (not shown) which a player can operate preferably while sitting. As illustrated by the different configurations shown in FIGS. 1A and 1B, the gaming device can be constructed with varying cabinet and display configurations.

In several embodiments, the electronic gaming devices, for example, as shown in FIGS. 1A-1D, may comprise all or part of a general purpose computer system, for example, the general purpose computer system of FIG. 2. It should be appreciated, however, the general purpose computing system of FIG. 2 is merely an exemplary embodiment of an electronic device, and actual electronic devices may comprise any one or more components shown in FIG. 2A, suitable for embodiments of the present invention.

With reference to FIG. 2A, a general purpose computer system in the form of a computer 210 is shown. As understood by embodiments of the present invention, components shown in dashed outline are not part of the computer 210, but are used to illustrate the exemplary embodiment of FIG. 2A. Components of computer 210 may include, but are not limited to, a processor 220, a system memory 230, a memory/graphics interface 221, also known as a Northbridge chip, and an I/O interface 222, also known as a Southbridge chip. The system memory 230 and a graphics processor 290 may be coupled to the memory/graphics interface 221. A monitor 291 or other graphic output device may be coupled to the graphics processor 290.

A series of system busses may couple various system components including a high speed system bus 223 between the processor 220, the memory/graphics interface 221 and the I/O interface 222, a front-side bus 224 between the memory/graphics interface 221 and the system memory 230, and an advanced graphics processing (AGP) bus 225 between the memory/graphics interface 221 and the graphics processor 290. The system bus 223 may be any of several types of bus structures including, by way of example, and not limitation, such architectures include Industry Standard Architecture (ISA) bus, Micro Channel Architecture (MCA) bus and Enhanced ISA (EISA) bus. As system architectures evolve, other bus architectures and chip sets may be used but often generally follow this pattern. For example, companies such as Intel and AMD support the Intel Hub Architecture (IHA) and the Hypertransport architecture, respectively.

The computer 210 typically includes a variety of computer readable media. Computer readable media can be any available media that can be accessed by computer 210 and includes both volatile and nonvolatile media, removable and non-removable media. By way of example, and not limitation, computer readable media may comprise computer storage media and communication media. Computer storage media includes volatile and nonvolatile, removable and non-removable media implemented in any method or technology for storage of information such as computer readable instructions, data structures, program modules or other data. Computer storage media includes, but is not limited to, RAM, ROM, EEPROM, flash memory or other memory technology, CD-ROM, digital versatile disks (DVD) or other optical disk storage, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, or any other medium that can be used to store the desired information and can accessed by the computer 210.

Communication media typically embodies computer readable instructions, data structures, program modules or other data in a modulated data signal such as a carrier wave or other transport mechanism and includes any information delivery media. The term “modulated data signal” means a signal that has one or more of its characteristics set or changed in such a manner as to encode information in the signal. By way of example, and not limitation, communication media includes wired media such as a wired network or direct-wired connection, and wireless media such as acoustic, RF, infrared and other wireless media. Combinations of the any of the above should also be included within the scope of computer readable media.

The system memory 230 includes computer storage media in the form of volatile and/or nonvolatile memory such as read only memory (ROM) 231 and random access memory (RAM) 232. The system ROM 231 may contain permanent system data 243, such as identifying and manufacturing information. In some embodiments, a basic input/output system (BIOS) may also be stored in system ROM 231. RAM 232 typically contains data and/or program modules that are immediately accessible to and/or presently being operated on by processor 220. By way of example, and not limitation, FIG. 2 illustrates operating system 234, application programs 235, other program modules 236, and program data 237.

The I/O interface 222 may couple the system bus 223 with a number of other buses 226, 227 and 228 that couple a variety of internal and external devices to the computer 210. A serial peripheral interface (SPI) bus 226 may connect to a BIOS memory 233 containing the basic routines that help to transfer information between elements within computer 210, such as during start-up.

In some embodiments, a security module 229 may be incorporated to manage receipt of money/credits, issuance of money/credits, and enforcement of policies, as may be required in the gaming industry. In many embodiments, such security module 229 may be coupled with a payment acceptor built into a physical machine. A payment acceptor may include a coin slot and a payment, note or bill acceptor, where the player inserts money, coins or tokens. For example, the player can place coins in the coin slot or paper money, ticket or voucher into the payment, note or bill acceptor. In other embodiments, devices such as readers or validators for credit cards, debit cards or credit slips could be used for accepting payment. In one embodiment, a player may insert an identification card into a card reader of the gaming device. In one embodiment, the identification card is a smart card having a programmed microchip or a magnetic strip coded with a player's identification, credit totals and other relevant information. In one embodiment, money may be transferred to a gaming device through electronic funds transfer. When a player funds the gaming device, the processor determines the amount of funds entered and the corresponding amount is shown on the credit or other suitable display as described above.

A super input/output chip 260 may be used to connect to a number of ‘legacy’ peripherals, such as floppy disk 252, keyboard/mouse/buttons 262, and printer 296, as examples. The super I/O chip 260 may be connected to the I/O interface 222 with a low pin count (LPC) bus, in some embodiments. The super I/O chip 260 is widely available in the commercial marketplace.

In one embodiment, bus 228 may be a Peripheral Component Interconnect (PCI) bus, or a variation thereof, may be used to connect higher speed peripherals to the I/O interface 222. A PCI bus may also be known as a Mezzanine bus. Variations of the PCI bus include the Peripheral Component Interconnect-Express (PCI-E) and the Peripheral Component Interconnect-Extended (PCI-X) busses, the former having a serial interface and the latter being a backward compatible parallel interface. In other embodiments, bus 228 may be an advanced technology attachment (ATA) bus, in the form of a serial ATA bus (SATA) or parallel ATA (PATA).

The computer 210 may also include other removable/non-removable, volatile/nonvolatile computer storage media. By way of example only, FIG. 2A illustrates a hard disk drive 240 that reads from or writes to non-removable, nonvolatile magnetic media. Removable media, such as a universal serial bus (USB) memory 252 or CD/DVD drive 256 may be connected to the PCI bus 228 directly or through an interface 250. Other removable/non-removable, volatile/nonvolatile computer storage media that can be used in the exemplary operating environment include, but are not limited to, magnetic tape cassettes, flash memory cards, digital versatile disks, digital video tape, solid state RAM, solid state ROM, and the like.

The drives and their associated computer storage media, discussed above and illustrated in FIG. 2A, provide storage of computer readable instructions, data structures, program modules and other data for the computer 210. In FIG. 2A, for example, hard disk drive 240 is illustrated as storing operating system 244, application programs 245, other program modules 246, and program data 247. Note that these components can either be the same as or different from operating system 234, application programs 235, other program modules 236, and program data 237. Operating system 244, application programs 245, other program modules 246, and program data 247 are given different numbers here to illustrate that, at a minimum, they are different elements within the computer 210. A user may enter commands and information into the computer 210 through input devices such as a mouse/keyboard 262 or other input device combination. Other input devices (not shown) may include a microphone, joystick, game pad, satellite dish, scanner, or the like. These and other input devices are often connected to the processor 220 through one of the I/O interface busses, such as the SPI 226, the LPC 227, or the PCI 228, but other busses may be used. In some embodiments, other devices may be coupled to parallel ports, infrared interfaces, game ports, and the like (not depicted), via the super I/O chip 260.

The computer 210 may operate in a networked environment using logical connections to one or more remote computers, such as a remote computer 280 via a network interface controller (NIC) 270. The remote computer 280 may be a personal computer, a server, a router, a network PC, a peer device or other common network node, and typically includes many or all of the elements described above relative to the computer 210. The logical connection between the NIC 270 and the remote computer 280 depicted in FIG. 2 may include a local area network (LAN), an Ethernet-based network, a wide area network (WAN), or both, but may also include other networks. Such networking environments are commonplace in offices, enterprise-wide computer networks, intranets, and the Internet.

Returning to FIGS. 1A-1D, 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.

As shown by FIGS. 1A and 1B, and supported by the elements depicted in FIG. 2A, many embodiments of the present invention comprise at least one, and often a plurality, of input devices in communication with the processor. The input devices can include any suitable device which enables the player to produce an input signal which is read by the processor, for instructing the game and/or gaming device to do something. In one embodiment, after appropriate funding of the gaming device, the input device is a game activation device, such as a pull arm 32 or a play button 34 which is used by the player to start any primary game or sequence of events in the gaming device. The play button can be any suitable play activator such as a bet one button, a max bet button or a repeat the bet button. In one embodiment, upon appropriate funding, the gaming device begins the game play automatically. In another embodiment, upon the player engaging one of the play buttons, the gaming device automatically activates game play.

In one embodiment, as shown in FIGS. 1A and 1B, one input device is a bet one button 36. The player places a bet by pushing the bet one button. 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 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, one input device is a touch-screen coupled with a touch-screen controller, or some other touch-sensitive display overlay to allow for player interaction with the images on the display. The touch-screen and the touch-screen controller are connected to a video controller. A player can make decisions and input signals into the gaming device by touching touch-screen at the appropriate places.

In one embodiment, the gaming device includes a sound generating device controlled by one or more sound cards which function in conjunction with the processor. In one embodiment, the sound generating device includes at least one and preferably a plurality of speakers or other sound generating hardware and/or software for generating sounds, such as playing music for the primary and/or secondary game or for other modes of the gaming device, such as an attract mode. In one embodiment, the gaming device provides dynamic sounds coupled with attractive multimedia images displayed on one or more of the display devices to provide an audio-visual representation or to otherwise display full-motion video with sound to attract players to the gaming device. During idle periods, the gaming device may display a sequence of audio and/or visual attraction messages to attract potential players to the gaming device. The videos may also be customized for or to provide any appropriate information.

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.

Suitable gaming devices may incorporate any suitable wagering primary or base game. The gaming machine or device of embodiments 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 an embodiment of the present invention.

In one embodiment, a base or primary game may be a slot game with one or more paylines 52. The paylines may be horizontal, vertical, circular, diagonal, angled or any combination thereof. In this embodiment, the gaming device displays at least one and preferably a plurality of reels 54, for example, having three to five reels 54 in either electromechanical form with mechanical rotating reels or video form with simulated reels and movement thereof. In one embodiment, an electromechanical slot machine includes a plurality of adjacent, rotatable wheels which may be combined and operably coupled with an electronic display of any suitable type. In another embodiment, if the reels 54 are in video form, the plurality of simulated video reels 54 are displayed on one or more of the display devices as described above. Each reel 54 displays a plurality of indicia such as bells, hearts, fruits, numbers, letters, bars or other images which may generally correspond to a theme associated with the gaming device. In this embodiment, the gaming device awards prizes when the reels of the primary game stop spinning if specified types and/or configurations of indicia or symbols occur on an active pay line or otherwise occur in a winning pattern.

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 FIGS. 1A and 1B. In another embodiment, the triggering event or qualifying condition may be by exceeding a certain amount of game play (number of games, number of credits, amount of time), reaching a specified number of points earned during game play or as a random award.

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 FIG. 2B, one or more of the gaming devices 10 of embodiments of the present invention may be connected to each other through a data network or a remote communication link 58 with some or all of the functions of each gaming device provided at a central location such as a central server or central controller 56. More specifically, the processor of each gaming device may be designed to facilitate transmission of signals between the individual gaming device and the central server or controller.

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 an embodiment 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 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 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 each other.

In another embodiment, the data network is a global computer network, such as the Internet, or an intranet network, and the gaming system may be considered an online system, a mobile system, or the like. In this embodiment, the operation of the gaming device can be viewed at the gaming device with at least one web browser, or application, such that access to the data network is feasible.

In a base example game, an individual “Sam Slotsky,” is standing in front of a nickel-denomination version of an embodiment of the present invention. Sam sees slot game on the slot game on a video display 400, illustrated for example in FIG. 3. The slot game uses a 5-column by 3-row symbol matrix, as shown on the slot reels 402-410. For this example, video display 400 is populated with symbols and/or information described below which replaces the symbols and/or information currently displayed in FIG. 3.

Below the video display 400, the button panel holds seven buttons: Cash Out 412, Pay Table 414, Help 416, Select Pay Lines 418, Bet Per Line 420, Bet Max 422, and Spin 424. In addition, there are also five meters on the video display 400 below the game: Credits 426, Number of Pay Lines 428, Amount Bet Per Line 430, Total Bet 432 and Paid 434.

Sam presses the Pay Table button 414 to view the pays for winning combinations. After viewing the pay table, Sam deposits $20 into the bill receptor and the Credits meter 426 counts up from 0 to 400 since the denomination for this game is five cents per credit. Sam then his chooses the wager for the game: The game's Number of Pay Lines meter 428 reads 1. Sam presses the Select Pay Lines button 418 four times and the Number of Pay Lines meter 428 counts up from 1 to 5. An exemplary set of paylines used in this example is illustrated in FIG. 11. As Sam presses the Select Pay Lines button 418, the video display 400 shows the locations of each selected pay line on the slot reels 402-410. For example, the first pay line 502 starts in the middle row of slot reel 402 and proceeds in the straight line through the middle position of slot reels 404-410; The game's Amount Bet Per Line meter 430 reads 1. Sam presses the Bet Per Line button 420 two times and the Amount Bet Per Line meter 430 counts up from 1 to 3; The Total Bet meter 432 started at 1, but after Sam's adjustments it now reads 15; and The Paid meter 434 reads 0.

After setting his wager, Sam presses the spin button 424. The Credits meter 426 counts down from 400 to 385. The slot reels 402-410 spin, stop, and display a variety of symbols. The “before” symbol matrix contained no winning combinations. The “after” symbol matrix, however, contains a winning 5-5-D combination on pay line 1 at 502. The winning combination is formed by the extension of the D wild symbol from the top position of slot reel 406 into the middle and bottom positions of slot reel 406.

The game awards 75 credits for the winning symbol combination of 5-5-D. The D symbol is wild and acts as a 5 symbol to make the 5-5-5 combination. The 75 credit award reflects the game's pay table which states that 5-5-5 pays 25 credits for each credit wagered upon the pay line (e.g., 25 credits times 3 credits wagered on the pay line). The Credits meter 426 counts up from 385 to 460 and the game Paid meter 434 reads 75.

Again, Sam presses the spin button 424. The Credits meter 426 counts down from 460 to 445. The slot reels 402-410 spin, stop, and display other symbols. The “before” symbol matrix contains 2 winning combinations of 8-U-D on pay line 4 at 508 and 4-4-D on pay line 3 at 506. The “after” symbol matrix, contains an additional winning combination of 8-U-8-8 on pay line 1 at 502. The additional winning combination is formed by the extension of the U wild symbol from the middle position of slot reel 404 into the top position of slot reel 404.

The game awards 930 credits for the winning combinations, as follows: The game awards 300 credits for the winning symbol combination of 8-U-D. The U and D symbols are wild and act as 8 symbols to make the 8-8-8 combination. The 300 credit award reflects the game's pay table which states that 8-8-8 pays 100 credits for each credit wagered upon the pay line (e.g., 100 credits times 3 credits wagered on the pay line). The game awards 30 credits for the winning symbol combination of 4-4-D. The D symbol is wild and acts as a 4 symbol to make the 4-4-4 combination. The 30 credit award reflects the game's pay table which states that 4-4-4 pays 10 credits for each credit wagered upon the pay line (e.g., 10 credits times 3 credits wagered on the pay line). The game awards 600 credits for the winning symbol combination of 8-U-8-8. The U symbol is wild and act as an 8 symbol to make the 8-8-8-8 combination. The 600 credit award reflects the game's pay table which states that 8-8-8-8 pays 200 credits for each credit wagered upon the pay line (e.g., 200 credits times 3 credits wagered on the pay line).

The Credits meter 426 counts up from 445 to 1375 and the game Paid meter 434 reads 930. Again, Sam presses the spin button 424. The Credits meter 426 counts down from 460 to 445. The slot reels 402-410 spin, stop, and display additional symbols. The “before” symbol matrix contains 1 winning combination of 3-U-3 on pay line 2 at 504. The “after” symbol matrix, extends the 3-U-3 combination into 3-U-3-U-3 and also contains an additional 2 winning combinations of 4-4-D-U on pay line 3 at 506 and 3-3-D-U-3 on pay line 4 at 508. The additional winning combinations are formed by the extension of the D wild symbol from the middle position of slot reel 406 into the bottom position of slot reel 406 and the extension of the U wild symbol from the bottom position of slot reel 408 into the middle and top position of slot reel 408.

The game awards 300 credits for the winning combinations, as follows: The game awards 120 credits for the winning symbol combination of 3-U-3-U-3. The U symbols are wild and act as 3 symbols to make the 3-3-3-3-3 combination. The 120 credit award reflects the game's pay table which states that 3-3-3-3-3 pays 40 credits for each credit wagered upon the pay line (e.g., 40 credits times 3 credits wagered on the pay line). It should be noted that the game only awards credits for the 3-U-3-U-3 combination formed after expansion; no credits are issued for the 3-U-3 combination formed before expansion. However, in alternative embodiments, credits may be issued prior to, and after expansion. The game awards 60 credits for the winning symbol combination of 4-4-D-U. The D and U symbols are wild and acts as 4 symbols to make the 4-4-4-4 combination. The 60 credit award reflects the game's pay table which states that 4-4-4-4 pays 20 credits for each credit wagered upon the pay line (e.g., 20 credits times 3 credits wagered on the pay line). The game awards 120 credits for the winning symbol combination of 3-3-D-U-3. The U symbols are wild and act as 3 symbols to make the 3-3-3-3-3 combination. The 120 credit award reflects the game's pay table which states that 3-3-D-U-3 pays 40 credits for each credit wagered upon the pay line (e.g., 40 credits times 3 credits wagered on the pay line).

The Credits meter 426 counts up from 1360 to 1660 and the game Paid meter 434 reads 300. Content with his winnings, Sam presses the Cash Out button 412. The gaming device issues 1660 nickels or any other form of currency, including cash, an EZ-PAY™ ticket, or electronic payment.

During play of the base game, the player may receive pays for additional features, such as line and reel scatter pays. FIGS. 9 and 10 show scatter pays that award the player a predetermined payout for the appearance of line and reel scatter symbols on the slot reels 402-410. FIG. 9 shows a “line scatter pay” that issues awards for the 2 scatter symbols “11” on pay line 1 at 502; and FIG. 10 shows a “reel scatter pay” that issues awards for 3 scatter symbols “12” on the slot reels 402-410.

It should be noted that the U and D directional wild symbols in FIGS. 9 and 10 do not act as scatter symbols. Alternatively, directional wild symbols may also act as any or all types of scatter symbols, and optionally simultaneously therewith.

The Scatter pays illustrated in FIGS. 9 and 10 issue a specific number of credits. The credits may be issued immediately or after the completion of a bonus feature e.g., animation sequence or animated bonus game). The calculation of the scatter pay award depends on the type of scatter pay: For the line scatter pay, the number of credits wagered on the winning pay line multiplies the number of credits indicated by the pay table. In FIG. 9, the player wagered three credits each on five pay lines and collected three times the amount indicated on the pay table. For the reel scatter pay, the total number of credits wagered multiplies the number of credits indicated by the pay table. In FIG. 10, the player wagered fifteen total credits and collected fifteen times the amount indicated on the pay table. Alternatively, any award schedule may be used to pay for any pre-determined arrangement of scatter symbols—line-scatter or reel-scatter.

A variety of additional alternative embodiments of such type of system are disclosed by commonly owned U.S. Pat. No. 7,758,414, the disclosure of which is incorporated by reference herein in its entirety. In addition, certain features of U.S. patent application Ser. No. 12/221,658 are related to features of embodiments of the present invention, and the disclosure of such reference is hereby incorporated by reference herein in its entirety.

Embodiments of the present invention further include a variety of methods of play that can be programmed on an electronic video slot machine to enable wild symbols to be created in the play matrix. In a first exemplary method, “activated wilds” comprises wild versions of certain designated symbols placed on the reel strips, in addition to the regular versions of these symbols. If a wild version of a symbol appears in the play matrix then every regular version of the same symbol changes into its wild version, prior to any win evaluation. In an alternate embodiment, the presence of a designated symbol in the play matrix causes all symbols in a designated subset of the symbol set which also appear in the play matrix to change into wild symbols prior to the win evaluation.

In a second exemplary method, “wild connections” comprises one or more symbols on the reel strips designated as activator symbols. The presence of these activator symbols in the play matrix on a given spin causes symbols in certain predetermined positions in the symbol matrix to change into wild symbols. In many embodiments, if two such symbols appear in the play matrix then every symbol which occupies a position in the matrix on any connected pay line which includes both activator symbols is changed into a wild symbol.

In yet another embodiment, if two such activator symbols appear in the play matrix on the same row then every symbol on the row between them, as well as the activator symbols themselves are changed into wild symbols prior to the win evaluation. In an additional embodiment, if two such activator symbols appear in the play matrix on the same reel then every symbol on the reel between them, as well as the activator symbols themselves are changed into wild symbols prior to the win evaluation

It should be emphasized that the above-described embodiments of the present invention are merely possible examples of implementations, merely set forth for a clear understanding of the principles of the invention. Many variations and modifications may be made to the above-described embodiment(s) of the invention without departing substantially from the spirit and principles of the invention. For example, an element disclosed by one embodiment of the present invention may be included in any other disclosed embodiment, where suitable. All such modifications and variations are intended to be included herein within the scope of this disclosure and the present invention.
