The copyright owner has no objection to the facsimile reproduction by anyone of the patent disclosure, as it appears in the Patent and Trademark Office patent files or records, but otherwise reserves all copyright rights whatsoever.
The present invention relates generally to gaming machines, systems, apparatus, and methods and, more particularly, to gaming machines, systems, apparatus, and methods including one or more grouped held value symbols.
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 improve the operation of gaming apparatus and games played thereon by increasing processing speed and efficiency of usage of processing and/or memory resources. To make games more entertaining and exciting, they often offer the complexities of advanced graphics and special effects, multiple bonus features with different game formats, and multiple random outcome determinations per feature. The game formats may, for example, include picking games, reel spins, wheel spins, and other arcade-style play mechanics. Inefficiencies in processor execution of the game software can slow down play of the game and prevent a player from the playing the game at their desired pace.
According to certain aspects of the present invention, a gaming system includes a regulated gaming machine primarily dedicated for use in playing at least one regulated casino wagering game. The gaming machine includes an electronic display device and one or more electronic input devices and game-logic circuitry configured to detect, via at least one of the one or more electronic input devices, a physical item associated with a monetary value that establishes a credit balance and to initiate the casino wagering game in response to an input indicative of a wager covered by the credit balance. In response to a triggering event: the game logic circuitry is further configured to initiate play of a feature game including randomly selecting a set of symbols from a plurality of symbols, the plurality of symbols including standard symbols and value symbols and to display the set of symbols in an array on the electronic display device. The value symbols are associated with one or more values and are held in place in a group on the electronic display device. One or more of the standard symbols are replaced with respective replacement symbols randomly selected from the plurality of symbols. In response to the replacement symbols including another one or more of the value symbols, the new value symbols may be added to the group and at least one of the values of the symbols previously in the group is modified. At the conclusion of the feature game, an award based on the cumulative current value of the held value symbols is determined. At the conclusion of game play, the game-logic circuitry is configured to receive, via at least one of the one or more electronic input devices, a cashout input that initiates a payout from the credit balance.
According to other aspects of the present invention, a gaming system includes a regulated gaming machine primarily dedicated for use in playing at least one regulated casino wagering game. The gaming machine includes an electronic display device and one or more electronic input devices and means for detecting, via at least one of the one or more electronic input devices, a physical item associated with a monetary value that establishes a credit balance and for initiating the casino wagering game in response to an input indicative of a wager covered by the credit balance. In response to a triggering event: the gaming system further includes: means for initiating play of a feature game including randomly selecting a set of symbols from a plurality of symbols, the plurality of symbols including standard symbols and value symbols; means for displaying the set of symbols in an array on the electronic display device, the value symbols being associated with one or more values; means for holding one or more of the value symbols in place in a group on the electronic display device; means for replacing one or more of the standard symbols with respective replacement symbols randomly selected from the plurality of symbols; and, when the replacement symbols include another one or more of the value symbols, means for adding the another one or more of the value symbols to the group and for modifying at least one of the values of the symbols previously in the group; and means for awarding the current cumulative value of the held value symbols. At the conclusion of game play, the gaming system also includes means for receiving, via at least one of the one or more electronic input devices, a cashout input that initiates a payout from the credit balance.
In accordance with another embodiment, a method of operating a gaming system that includes a regulated gaming machine primarily dedicated for use in playing at least one regulated casino wagering game, the gaming machine including an electronic display device and one or more electronic input devices and game-logic circuitry for detecting, via at least one of the one or more electronic input devices, a physical item associated with a monetary value that establishes a credit balance includes the step of initiating the casino wagering game in response to an input indicative of a wager covered by the credit balance. In response to a triggering event: the method further includes steps for: initiating play of a feature game including randomly selecting a set of symbols from a plurality of symbols, the plurality of symbols including standard symbols and value symbols; for displaying the set of symbols in an array on the electronic display device, the value symbols being associated with one or more values; for holding one or more of the value symbols in place in a group on the electronic display device; for replacing one or more of the standard symbols with respective replacement symbols randomly selected from the plurality of symbols; and, in response to the replacement symbols including another one or more of the value symbols, for adding the another one or more of the value symbols to the group and for modifying at least one of the values of the symbols previously in the group; and for awarding the cumulative current value of the held value symbols. At the conclusion of game play, the method includes the step of receiving, via at least one of the one or more electronic input devices, a cashout input that initiates a payout from the credit balance.
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 may be subject to approval for use in one of more regulated gaming jurisdictions. 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 the primary display 18, a secondary display 20, and one or more audio speakers. 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, one or more buttons 26 on a button panel and/or other player-input devices, a bill/ticket acceptor 28, a card reader/writer and/or 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. The value input devices are used to deposit cash or credits onto the gaming machine 10. The cash or credits are used to fund wagers placed on the wagering game played via the gaming machine 10. Examples of value input devices include, but are not limited to, a coin acceptor, the bill/ticket acceptor 28, the card reader/writer 30, a wireless communication interface for reading cash or credit data from a nearby mobile device, and a network interface for withdrawing cash or credits from a remote account via an electronic funds transfer. A value input device is configured to detect a physical item, such as coins, currency, cards, etc., 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, for example, at a minimum of 100 Hz (100 calls per second) as set forth in Nevada's New Gaming Device Submission Package. Accordingly, the RNG cannot be carried out manually by a human and is integral to operating the game. For purposes of the present detailed description, the term “randomly determine” or “randomly select” is intended to include the use of either a pseudo-RNG or physical RNG in the determination of a value, outcome or element.
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 response to receiving an input indicative of a wager covered by the credit balance on the “credits” meter 84, the reels 82 are rotated and stopped to place symbols on the reels in visual association with paylines such as paylines 88. The wagering game evaluates the displayed array of symbols on the stopped reels and provides immediate awards and bonus features in accordance with a pay table. The pay table may, for example, include “line pays” or “scatter pays.” Line pays occur when a predetermined type and number of symbols appear along an activated payline, typically in a particular order such as left to right, right to left, top to bottom, bottom to top, etc. Scatter pays occur when a predetermined type and number of symbols appear anywhere in the displayed array without regard to position or paylines. Similarly, the wagering game may trigger bonus features based on one or more bonus triggering symbols appearing along an activated payline (i.e., “line trigger”) or anywhere in the displayed array (i.e., “scatter trigger”). The wagering game may also provide mystery awards and features independent of the symbols appearing in the displayed array.
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).

Though not shown, in some embodiments, a new border will surround any three or more value symbols outside of border 480 that are adjacent to one another. For each spin, if the number of surrounded value symbols has increased since the previous spin, the value assigned to each surrounded value symbol will increase. In one or more embodiments, the amount each value increases is equal to the number of credits wagered on the game, in this example, 250. In these and similar embodiments, such a fixed increment amount reduces how often the RNG must be used to determine the intermediate and final awards of the feature game. In some embodiments, if more than a certain number of value symbols appear on the screen, for example, 10, the amount each assigned value increases may be a higher multiple of the wager amount, for example, twice the wager amount. In other embodiments, other methods of increase, for example, random, may be employed. In still other embodiments, if the number of surrounded value symbols has increased since the previous spin, the number of remaining bonus spins may be reset to its original value (for example, 3, 4 or 5).

The original three value symbols within border 480 have had their original credit values increased from 750 to 1750, 250 to 1250, and 500 to 1500, respectively. Other value symbols within border 480 have had their initially assigned credit values increased as well. Because the value symbols at the top of the fourth and fifth columns did not have a third (or more) value symbols land adjacent to them during any of the spins, they are not surrounded by a border and no credit values were assigned to them, though they remained locked in place during all spins after their initial appearance.
With the feature game at its conclusion, the values assigned to each of the value symbols are totaled (500+500+750+1000+1750+1250+1500+250) and an award of 7500 credit is added to the game's credit meter or otherwise awarded to the player of the game (as a hand pay, for example). During the feature game, non-value symbols are not active and are not used for evaluating for winning combinations according to a pay table.
In accordance with one or more embodiments, instead of a credit value, a special annotation may be assigned to a particular value symbol, either when it first triggers the feature game, when it first appears adjacent to border 480 or when its value is increased as a result of subsequent spins. For example, a representation of a particular prize such as a mini-, minor-, major- or grand-bonus or jackpot, which may or not be a progressive prize, may be placed on the symbol in lieu of a credit amount.
While the above examples are described within the context of a feature game, it is equally contemplated that the invention can be practiced within the context of the basic wagering game. Though adjacent value symbols are grouped in the above example by surrounding them with a border, in one or more embodiments, a group is sufficiently formed if value symbols of a like type appear anywhere in the matrix, whether adjacent or not. In these embodiments, an indication that a value symbol is a member of a group may, as one non-limiting example, be shown graphically by highlighting each member of the group.
In block 505 of
In block 510, a certain number of value symbols, such as the 3, 4 or 5 “heart” symbols described above with respect to the example of
In block 515, each of the value symbols is assigned an initial numeric credit value, which is displayed upon each of the value symbols. In the example of
In block 520, a border or other designation groups each of the adjacent value symbols. During the bonus spins, these and any additional value symbols displayed on the matrix will be superimposed over their positions in the matrix (locked in place) and will replace any reel symbol appearing at their position. In one or more embodiments, the only active symbols during the bonus spins are the value symbols.
In block 525, the number of triggering symbols (for example, 3, 4, or 5) may be used to determine a number of feature game spins. In other embodiments, the number of spins awarded may be based on other factors, such as, but not limited to, the total credits wagered on the game.
In block 530, during the feature game spins, any value symbols currently displayed on the matrix will be superimposed over their positions in matrix (locked in place) and will replace any reel symbol appearing at their respective positions.
In block 535, any unlocked symbol positions of the matrix are repopulated by, for example, spinning the reels underlying any locked value symbols.
In decision block 540, it is determined whether any additional value symbols have been added to the matrix as a result of its repopulation. If not, flow proceeds to block 565, where the number of remaining bonus spins is decremented. Flow then proceeds to decision block 570. If, however, additional value symbols have been added to the matrix, any value symbols adjacent to the border around previously grouped adjacent value symbols is expanded to include the new adjacent symbols in block 545. In block 550, an initial value is assigned to the newly appearing value symbols within the border as described in the description of block 515.
In block 555, the values assigned to adjacent value symbols previously within the bordered area of the matrix are increased. In one or more embodiments, the amount each value increases is equal to the number of credits wagered on the game, for example, 250. In some embodiments, if more than a certain number of value symbols appear on the screen, for example, 10, the amount each assigned value increases may be a higher multiple of the wager amount, for example, twice the wager amount. In other embodiments, other methods of increase, for example, random, may be employed.
In decision block 560, a determination is made whether the number of remaining bonus spins has been exhausted. If yes, flow proceeds to block 580, where the feature game ends. If not, in accordance with some embodiments, an additional determination may be made whether the matrix currently displays more than a certain number (for example, 15) value symbols. If yes, flow proceeds to block 580, where the feature game ends. If no, flow proceeds to block 530, where another “spin” of the feature game occurs.
The order of actions as shown in
Referring now to
In this embodiment, the feature game is triggered when a particular number of bonus trigger symbols, for example, seven, appear during play of a base game (not shown). The trigger symbols are collected and randomly placed in positions of matrix 640 at the start of the feature game. The remaining individual reels spin to reveal value symbols 620 or blanks (in this example, value symbols 620 comprise gems of various colors and/or shapes). When all reels have been spun, any locations displaying non-blank symbols, in this case gems, will have their displayed symbols “fall” to the lowest non-blank position in their respective columns, leaving a blank symbol in their original positions. Matching gems fuse together when in a 2×2 or larger rectangle. Upon being fused together to create larger gem symbols, as illustrated, for example, by gem 660, a credit value is assigned to the fused symbol. Different types of gems may have values assigned to them based on a list of possible credit values associated with each gem type. In one or more embodiments, certain gems are wild and may substitute for any gem type for the purpose of creating fused gems. In accordance with one or more embodiments, the fusing of one or more gems may reset the number of free spins available during the feature game. In accordance with still other embodiments, the feature game may end when no gems appear during a set of spins or when the number of spins available decrements to zero. At the conclusion of the feature game, an award based on the displayed credit values on each of the fused gems is paid to the player. In accordance with some embodiments, a special award, which may include a progressive award, may be awarded in the case of the entire matrix 640 filling with gem symbols. In still other embodiments, various progressive awards may be assigned to fused gems of certain sizes. For example, a minor progressive may be assigned to a fused gem comprised of 6 original gems, whereas a larger progressive may be assigned to a fused gem comprised of 10 original gems.
In block 705 of
In block 710, a number of bonus spins is determined. In one or more embodiments, the number of triggering symbols may be a factor in determining a number of feature game spins. In other embodiments, the number of spins awarded may be based on other factors, such as, but not limited to, the total credits wagered on the game.
In block 715, a certain number of value symbols, such as the “gem” symbols described above with respect to the example of
In block 720, the unpopulated symbol positions of the matrix are populated by, for example, spinning the reel associated with each unpopulated symbol position.
In block 725, when all the remaining reels have been spun, any locations displaying non-blank symbols, in this case gems, will have their displayed symbols “fall” to the lowest non-blank position in their respective columns, leaving a blank symbol in their original positions.
In block 730, matching adjacent value symbols fuse together when in a 2×2 or larger rectangle. In one or more embodiments, different types of gems may have values assigned to them based on a list of possible credit values associated with each gem type. In some embodiments, certain gems are wild and may substitute for any gem type for the purpose of creating fused gems. After being fused together to create larger value symbols, a credit value is assigned to the fused symbol in block 735.
In decision block 740, it is determined whether the array is full of value symbols. If so, a special award, for example, a progressive award, may be awarded at block 745 and the feature game is terminated at block 765.
If the array is not full, in decision block 540, it is determined whether any additional value symbols have been added to the matrix as a result of spins that occurred in block 720. If not, the feature game is terminated at block 765. If so, flow proceeds to block 755, where the number of remaining bonus spins is decremented.
In decision block 760, a determination is made whether the number of remaining bonus spins has been exhausted. If yes, flow proceeds to block 765, where the feature game ends. If no, flow proceeds to block 720, where another “spin” of the feature game occurs.
The order of actions as shown in
In accordance with other embodiments employing fused symbols, when a feature game trigger occurs, the value symbols are placed and then held in place in the matrix. All other symbols are replaced by a random selection of blank/greyed out symbols from the base game. Any value symbols that are adjacent to each other are then automatically fused to create larger symbols in shapes, for example, shown in
In accordance with some embodiments, fused symbols are formed according to defined ‘blocks’ of symbols (2×1; 3×1; 2×2; etc.), where blocks are formed in an order of preference, for example, based on size, then height. For example, if value symbols had landed in the array of
Once all value symbol transformations are complete, a number of additional spins are awarded, as described above. Individual reels will spin in each of the symbol positions and only value symbols or a blank/greyed out symbol will appear on each reel. Any additional value symbols that land are held for the duration of the feature game and those that land adjacent to existing value symbols will automatically transform into larger fused symbols as indicated above.
In accordance with one or more embodiments, when a value symbol is held in position as indicated above, it may be designated as occupying a first layer at its location on the matrix. An individual reel associated with the location will still spin during each subsequent play of the feature game. Should another value symbol land in a position in the matrix already occupied by a held value symbol, the new value symbol may be designated as occupying a second layer at that location. Value symbols that land in each layer are held for the duration of the feature game and those that land adjacent to existing value symbols in their respective layer will automatically transform into larger fused symbols as indicated above.
Once all spins are complete, a reel associated with each fused symbol (in one or more layers) is revealed and spun to determine a prize for the fused symbol. Each symbol on this reel represents a potential credit prizes or progressive jackpots. The larger a fused symbol, the larger the credit prizes or progressive jackpots available on the reel. All determined prizes are held until all value symbol reels have been spun and prizes determined, at which point the total of all of the sub-prizes is awarded and the feature game ends.
