The present invention relates to a technological improvement to gaming systems, gaming machines, and methods and, more particularly, to new and improved animations in connection with a symbol array feature.
The gaming industry depends upon player participation. Players are generally “hopeful” players who either think they are lucky or at least think they can get lucky—for a relatively small investment to play a game, they can get a disproportionately large return. To create this feeling of luck, a gaming apparatus relies upon an internal or external random element generator to generate one or more random elements such as random numbers. The gaming apparatus determines a game outcome based, at least in part, on the one or more random elements.
A significant technical challenge is to improve the operation of gaming apparatus and games played thereon, including the manner in which they leverage the underlying random element generator, by making them yield a negative return on investment in the long run (via a high quantity and/or frequency of player/apparatus interactions) and yet random and volatile enough to make players feel they can get lucky and win in the short run. Striking the right balance between yield versus randomness and volatility to create a feeling of luck involves addressing many technical problems, some of which can be at odds with one another. This luck factor is what appeals to core players and encourages prolonged and frequent player participation. As the industry matures, the creativity and ingenuity required to improve such operation of gaming apparatus and games grows accordingly.
Another significant technical challenge is to provide a new and improved level of game play that uses new and improved gaming apparatus animations. Improved animations represent improvements to the underlying technology or technical field of gaming apparatus and, at the same time, have the effect of encouraging prolonged and frequent player participation.
According to an embodiment of the present invention, there is provided a gaming system, gaming machine, and method that utilize an electronic display device configured to display a plurality of symbol-bearing reels and an array of symbol positions. The array of symbol positions comprises a plurality of rows and columns. The plurality of symbol-bearing reels are spun and stopped to land symbols on the reels in the symbol positions of the array. Payouts are awarded for any winning symbol combinations along horizontal and vertical ways. In response to a triggering event, the array is expanded by expanding one or more of the rows of the array to add one or more symbol positions to each expanded row. The plurality of symbol-bearing reels are again spun and stopped to land symbols on the reels in the symbol positions of the expanded array. Payouts are again awarded for any winning symbol combinations along the horizontal and vertical ways. The reels may be associated with the respective rows of the array such that each stopped reel serves to populate the symbol positions of a respective one of the rows.
Each horizontal way comprises symbol positions in respective consecutive ones of the columns starting with the leftmost symbol position of each row. Each vertical way comprises symbol positions in respective consecutive ones of the rows starting from the topmost row. Said another way, the symbols of any winning symbol combinations along the horizontal ways appear in respective consecutive ones of the columns starting with the leftmost symbol position of each row, and the symbols of any winning symbol combinations along the vertical ways appear in respective consecutive ones of the rows starting from the topmost row. In one embodiment, only the highest win is awarded per way.
Additional aspects of the invention will be apparent to those of ordinary skill in the art in view of the detailed description of various embodiments, which is made with reference to the drawings, a brief description of which is provided below.
While the invention is susceptible to various modifications and alternative forms, specific embodiments have been shown by way of example in the drawings and will be described in detail herein. It should be understood, however, that the invention is not intended to be limited to the particular forms disclosed. Rather, the invention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the appended claims.
While this invention is susceptible of embodiment in many different forms, there is shown in the drawings and will herein be described in detail preferred embodiments of the invention with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the broad aspect of the invention to the embodiments illustrated. For purposes of the present detailed description, the singular includes the plural and vice versa (unless specifically disclaimed); the words “and” and “or” shall be both conjunctive and disjunctive; the word “all” means “any and all”; the word “any” means “any and all”; and the word “including” means “including without limitation.”
For purposes of the present detailed description, the terms “wagering game,” “casino wagering game,” “gambling,” “slot game,” “casino game,” and the like include games in which a player places at risk a sum of money or other representation of value, whether or not redeemable for cash, on an event with an uncertain outcome, including without limitation those having some element of skill. In some embodiments, the wagering game involves wagers of real money, as found with typical land-based or online casino games. In other embodiments, the wagering game additionally, or alternatively, involves wagers of non-cash values, such as virtual currency, and therefore may be considered a social or casual game, such as would be typically available on a social networking web site, other web sites, across computer networks, or applications on mobile devices (e.g., phones, tablets, etc.). When provided in a social or casual game format, the wagering game may closely resemble a traditional casino game, or it may take another form that more closely resembles other types of social/casual games.

The gaming machine 10 illustrated in
The input devices, output devices, and input/output devices are disposed on, and securely coupled to, the cabinet 12. By way of example, the output devices include a primary display 18, a secondary display 20, and one or more audio speakers 22. The primary display 18 or the secondary display 20 may be a mechanical-reel display device, a video display device, or a combination thereof in which a transmissive video display is disposed in front of the mechanical-reel display to portray a video image superimposed upon the mechanical-reel display. The displays variously display information associated with wagering games, non-wagering games, community games, progressives, advertisements, services, premium entertainment, text messaging, emails, alerts, announcements, broadcast information, subscription information, etc. appropriate to the particular mode(s) of operation of the gaming machine 10. The gaming machine 10 includes a touch screen(s) 24 mounted over the primary or secondary displays, buttons 26 on a button panel, a bill/ticket acceptor 28, a card reader/writer 30, a ticket dispenser 32, and player-accessible ports (e.g., audio output jack for headphones, video headset jack, USB port, wireless transmitter/receiver, etc.). It should be understood that numerous other peripheral devices and other elements exist and are readily utilizable in any number of combinations to create various forms of a gaming machine in accord with the present concepts.
The player input devices, such as the touch screen 24, buttons 26, a mouse, a joystick, a gesture-sensing device, a voice-recognition device, and a virtual-input device, accept player inputs and transform the player inputs to electronic data signals indicative of the player inputs, which correspond to an enabled feature for such inputs at a time of activation (e.g., pressing a “Max Bet” button or soft key to indicate a player's desire to place a maximum wager to play the wagering game). The inputs, once transformed into electronic data signals, are output to game-logic circuitry for processing. The electronic data signals are selected from a group consisting essentially of an electrical current, an electrical voltage, an electrical charge, an optical signal, an optical element, a magnetic signal, and a magnetic element.
The gaming machine 10 includes one or more value input/payment devices and value output/payout devices. In order to deposit cash or credits onto the gaming machine 10, the value input devices are configured to detect a physical item associated with a monetary value that establishes a credit balance on a credit meter such as the “credits” meter 84 (see
Turning now to
The game-logic circuitry 40 is also connected to an input/output (I/O) bus 48, which can include any suitable bus technologies, such as an AGTL+ frontside bus and a PCI backside bus. The I/O bus 48 is connected to various input devices 50, output devices 52, and input/output devices 54 such as those discussed above in connection with
The external system 60 includes, in various aspects, a gaming network, other gaming machines or terminals, a gaming server, a remote controller, communications hardware, or a variety of other interfaced systems or components, in any combination. In yet other aspects, the external system 60 comprises a player's portable electronic device (e.g., cellular phone, electronic wallet, etc.) and the external-system interface 58 is configured to facilitate wireless communication and data transfer between the portable electronic device and the gaming machine 10, such as by a near-field communication path operating via magnetic-field induction or a frequency-hopping spread spectrum RF signals (e.g., Bluetooth, etc.).
The gaming machine 10 optionally communicates with the external system 60 such that the gaming machine 10 operates as a thin, thick, or intermediate client. The game-logic circuitry 40—whether located within (“thick client”), external to (“thin client”), or distributed both within and external to (“intermediate client”) the gaming machine 10—is utilized to provide a wagering game on the gaming machine 10. In general, the main memory 44 stores programming for a random number generator (RNG), game-outcome logic, and game assets (e.g., art, sound, etc.)—all of which obtained regulatory approval from a gaming control board or commission and are verified by a trusted authentication program in the main memory 44 prior to game execution. The authentication program generates a live authentication code (e.g., digital signature or hash) from the memory contents and compare it to a trusted code stored in the main memory 44. If the codes match, authentication is deemed a success and the game is permitted to execute. If, however, the codes do not match, authentication is deemed a failure that must be corrected prior to game execution. Without this predictable and repeatable authentication, the gaming machine 10, external system 60, or both are not allowed to perform or execute the RNG programming or game-outcome logic in a regulatory-approved manner and are therefore unacceptable for commercial use. In other words, through the use of the authentication program, the game-logic circuitry facilitates operation of the game in a way that a person making calculations or computations could not.
When a wagering-game instance is executed, the CPU 42 (comprising one or more processors or controllers) executes the RNG programming to generate one or more pseudo-random numbers. The pseudo-random numbers are divided into different ranges, and each range is associated with a respective game outcome. Accordingly, the pseudo-random numbers are utilized by the CPU 42 when executing the game-outcome logic to determine a resultant outcome for that instance of the wagering game. The resultant outcome is then presented to a player of the gaming machine 10 by accessing the associated game assets, required for the resultant outcome, from the main memory 44. The CPU 42 causes the game assets to be presented to the player as outputs from the gaming machine 10 (e.g., audio and video presentations). Instead of a pseudo-RNG, the game outcome may be derived from random numbers generated by a physical RNG that measures some physical phenomenon that is expected to be random and then compensates for possible biases in the measurement process. Whether the RNG is a pseudo-RNG or physical RNG, the RNG uses a seeding process that relies upon an unpredictable factor (e.g., human interaction of turning a key) and cycles continuously in the background between games and during game play at a speed that cannot be timed by the player. Accordingly, the RNG cannot be carried out manually by a human and is integral to operating the game.
The gaming machine 10 may be used to play central determination games, such as electronic pull-tab and bingo games. In an electronic pull-tab game, the RNG is used to randomize the distribution of outcomes in a pool and/or to select which outcome is drawn from the pool of outcomes when the player requests to play the game. In an electronic bingo game, the RNG is used to randomly draw numbers that players match against numbers printed on their electronic bingo card.
The gaming machine 10 may include additional peripheral devices or more than one of each component shown in
In accord with various methods of conducting a wagering game on a gaming system in accord with the present concepts, the wagering game includes a game sequence in which a player makes a wager and a wagering-game outcome is provided or displayed in response to the wager being received or detected. The wagering-game outcome, for that particular wagering-game instance, is then revealed to the player in due course following initiation of the wagering game. The method comprises the acts of conducting the wagering game using a gaming apparatus, such as the gaming machine 10 depicted in
In the aforementioned method, for each data signal, the game-logic circuitry 40 is configured to process the electronic data signal, to interpret the data signal (e.g., data signals corresponding to a wager input), and to cause further actions associated with the interpretation of the signal in accord with stored instructions relating to such further actions executed by the controller. As one example, the CPU 42 causes the recording of a digital representation of the wager in one or more storage media (e.g., storage unit 56), the CPU 42, in accord with associated stored instructions, causes the changing of a state of the storage media from a first state to a second state. This change in state is, for example, effected by changing a magnetization pattern on a magnetically coated surface of a magnetic storage media or changing a magnetic state of a ferromagnetic surface of a magneto-optical disc storage media, a change in state of transistors or capacitors in a volatile or a non-volatile semiconductor memory (e.g., DRAM, etc.). The noted second state of the data storage media comprises storage in the storage media of data representing the electronic data signal from the CPU 42 (e.g., the wager in the present example). As another example, the CPU 42 further, in accord with the execution of the stored instructions relating to the wagering game, causes the primary display 18, other display device, or other output device (e.g., speakers, lights, communication device, etc.) to change from a first state to at least a second state, wherein the second state of the primary display comprises a visual representation of the physical player input (e.g., an acknowledgement to a player), information relating to the physical player input (e.g., an indication of the wager amount), a game sequence, an outcome of the game sequence, or any combination thereof, wherein the game sequence in accord with the present concepts comprises acts described herein. The aforementioned executing of the stored instructions relating to the wagering game is further conducted in accord with a random outcome (e.g., determined by the RNG) that is used by the game-logic circuitry 40 to determine the outcome of the wagering-game instance. In at least some aspects, the game-logic circuitry 40 is configured to determine an outcome of the wagering-game instance at least partially in response to the random parameter.
In one embodiment, the gaming machine 10 and, additionally or alternatively, the external system 60 (e.g., a gaming server), means gaming equipment that meets the hardware and software requirements for fairness, security, and predictability as established by at least one state's gaming control board or commission. Prior to commercial deployment, the gaming machine 10, the external system 60, or both and the casino wagering game played thereon may need to satisfy minimum technical standards and require regulatory approval from a gaming control board or commission (e.g., the Nevada Gaming Commission, Alderney Gambling Control Commission, National Indian Gaming Commission, etc.) charged with regulating casino and other types of gaming in a defined geographical area, such as a state. By way of non-limiting example, a gaming machine in Nevada means a device as set forth in NRS 463.0155, 463.0191, and all other relevant provisions of the Nevada Gaming Control Act, and the gaming machine cannot be deployed for play in Nevada unless it meets the minimum standards set forth in, for example, Technical Standards 1 and 2 and Regulations 5 and 14 issued pursuant to the Nevada Gaming Control Act. Additionally, the gaming machine and the casino wagering game must be approved by the commission pursuant to various provisions in Regulation 14. Comparable statutes, regulations, and technical standards exist in other gaming jurisdictions. As can be seen from the description herein, the gaming machine 10 may be implemented with hardware and software architectures, circuitry, and other special features that differentiate it from general-purpose computers (e.g., desktop PCs, laptops, and tablets).

At step 102, the game-logic circuitry initiates a wagering game. At step 104, the game-logic circuitry directs a display of the gaming machine to display a plurality of symbol-bearing reels and an array of symbol positions. The array of symbol positions comprises a plurality of rows and columns. The rows of the array are oriented in a horizontal direction, and the columns of the array are oriented in a generally vertical direction. Alternatively, the “rows” of the array may be oriented in a vertical direction, and the “columns” of the array may be oriented in a horizontal direction. The symbol positions in each row of the array are horizontally aligned with each other, and the symbol positions in each column of the array are vertically aligned with each other. The reels are associated with the respective rows of the array such that the reels spin horizontally in a direction illustrated by the arrows in
At step 106, a player enters play parameters such as a wager amount to be drawn from a credit balance and number of ways or lines along which winning symbol combinations must appear. To initiate a spin of the reels, the player may press a “Spin Reels” or “Max Bet” key on a button panel or touch screen. As shown in
At step 108, in response to the player initiating the reel spin, the game-logic circuitry generates a random game outcome using the above-referenced RNG. At step 110, the game-logic circuitry spins the reels (in the direction illustrated by the arrows in
At step 112, the game-logic circuitry provides awards for any winning symbol combinations in the active array. In one embodiment, payouts are awarded for any winning combinations along horizontal and vertical ways or lines. Each horizontal way comprises symbol positions in respective consecutive ones of the columns starting with the leftmost symbol position of each row. Each vertical way comprises symbol positions in respective consecutive ones of the rows starting from the topmost row. Said another way, the symbols of any winning symbol combinations along the horizontal ways appear in respective consecutive ones of the columns starting with the leftmost symbol position of each row, and the symbols of any winning symbol combinations along the vertical ways appear in respective consecutive ones of the rows starting from the topmost row. Only the highest win is awarded per horizontal way, and only the highest win is awarded per vertical way.
In the 6×4 active array shown in
At step 114, the game-logic circuitry determines whether or not the landed plurality of symbols include a bonus triggering combination. The bonus triggering combination may, for example, be a “scatter” combination comprising a threshold number of a particular symbol landing anywhere in the active array. In one embodiment, at least four scattered FREE symbols trigger a series of three free games. In other embodiments, the triggered number of free games may be more or less than three. If the reel spin does not result in the bonus trigger at step 114, the game-logic circuitry concludes the current game cycle at step 116. If, however, the reel spin results in the bonus trigger at step 114, flow proceeds to step 118 to conduct a series of free games with steps 118, 120, 122, 124, and 126. As shown in
At step 118, prior to each free game in the series, the game-logic circuitry randomly determines whether or not to expand the active array by expanding one or more of the rows of the array to add one or more symbol positions to each expanded row. This random determination may, for example, be a mystery event independent of any symbols landing in the array. If the game-logic circuitry determines not to expand the active array at step 118, the game-logic circuitry spins and stops the reels to populate the active array at step 122 and provides awards for any winning symbol combinations in the active array 124 as described above with respect to the wagered-on base game.
If, however, the game-logic circuitry determines to expand the active array at step 118, the game-logic circuitry directs the display to show new and improved animations expanding one or more rows of the active array at step 120. In one embodiment, multiple rows may expand at the same time and different rows may expand by varying numbers of symbol positions. Also, an expanding row always expands by the same number of symbol positions in opposite directions (i.e., the left and right directions) such that the expanding row may expand by one symbol position in each direction (for a total expansion of two symbol positions), two symbol positions in each direction (for a total expansion of four symbol positions), or so on. When a row is expanded, the reel associated with that row still populates all the symbol positions in that row: in effect, the number of adjacent symbols on the reel that are visible to the player is increased to correspond to the number of symbol positions in the expanded row. As shown in
At step 126, the game-logic circuitry determines whether or not the completed free game was the last free game in the series of free games. If it was the last free game, the game-logic circuitry concludes the game cycle at step 116. If, however, it was not the last free game, flow proceeds back to steps 118, 120, 122, and 124 to conduct another free game, including whether or not to further expand the active array at steps 118 and 120. If the array was expanded in a prior free game, the array remains expanded for any remaining subsequent free games and may be further expanded prior to each such free game. In each further expansion, multiple rows may expand at the same time, different rows may expand by varying numbers of symbol positions, and an expanding row expands by the same number of symbol positions in opposite directions (i.e., left and right directions).
In one embodiment, the series of free games can be retriggered by the appearance of at least four scattered FREE symbols in any free game. If retriggered, three free games are added to the current remaining number of free games.

In one embodiment, the game-logic circuitry applies constraints to row expansion. Specifically, any given row of the array can only expand if such expansion would cause that row to be no more than two positions larger than the number of symbol positions in any other row. In other words, after any expansion, the number of symbol positions in each of the rows will be within two symbol positions of each other. For example, if the number of symbol positions in rows one through six are 4, 4, 4, 4, 4, and 4, respectively, then on the current spin: (i) if any one of the rows does not expand, then the other rows can expand by no more than two symbol positions (for a total of six symbol positions in an expanded row); and (ii) if all the rows expand by two symbol positions, then any of the rows can further expand by another two symbol positions (for a total of eight symbol positions in the further expanded row). If the number of symbol positions in rows one through six are 4, 6, 6, 4, 4, and 6, respectively, then on the current spin: (i) if any one of rows one, four, and five does not expand, then rows two, three, and six cannot expand; and (ii) if rows one, four, and five each expand by two symbol positions, then (a) each of those rows can further expand by another two symbol positions, and/or (b) rows two, three, and six can each expand by two symbol positions. In the absence of the expansion constraint described above, a player could get frustrated by situations where the number of horizontal ways remains the same but the likelihood of achieving a win is reduced.
In another embodiment, a row may expand by one or more symbol positions in the left direction only, the right direction only, or both directions. If the rows are then shifted to keep the array symmetrical about a vertical center line, one or more rows may be horizontally offset from other rows by one-half symbol position. In yet another embodiment, after any expansion, the rows of the expanded array may be shifted so that the array is either left aligned (i.e., the leftmost symbol positions of the rows are aligned with each other) or right aligned (i.e., the rightmost symbol positions of the rows are aligned with each other). In a further embodiment, each symbol position of the active array is populated by a respective independent reel. Thus, in a 6×4 array for example, the 24 symbol positions are populated by 24 independent reels, respectively.
Each of these embodiments and obvious variations thereof is contemplated as falling within the spirit and scope of the claimed invention, which is set forth in the following claims. Moreover, the present concepts expressly include any and all combinations and subcombinations of the preceding elements and aspects.
This application is a continuation of U.S. patent application Ser. No. 17/487,918, filed Sep. 28, 2021, which claims the benefit of priority to U.S. Provisional Patent Application No. 63/105,508, filed Oct. 26, 2020, the contents of which are incorporated herein by reference in their entirety.
