     FIELD OF THE INVENTION 
     The present invention relates to a technological improvement to gaming systems, apparatus, and methods and, more particularly, to new and improved animations in connection with a symbol array persistence feature. 
     BACKGROUND OF THE INVENTION 
     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 playing the game at their desired pace. 
     Yet 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.

     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. 
     DETAILED DESCRIPTION 
     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. Embodiments may be combined with aspects of one embodiment supplementing or replacing aspects of another embodiment. 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. 
     Embodiments of the present invention comprise an innovative application of data processing steps that, when implemented by game-logic circuitry, direct an electronic display device to present a symbol-value aggregation process that minimizes processing overhead by utilizing numbered indicia to represent credit values instead of complex, fanciful game images. Further, the process aggregates displayed values borne by special symbols (i.e., value-bearing symbols) according to stored, variable criteria. In this way, the value-bearing symbols provide building blocks for innumerable different aggregation sequences simply by manipulating the aggregation criteria associated with the value-bearing symbols, resulting in fewer rules needed for the aggregation process than would be necessary for calculating values of winning symbol combinations enumerated in stored paytables, as found in prior art reel-spinning routines. At the same time, embodiments of the present invention provide a straightforward, what-you-see-is-what-you-get (WYSIWYG) visual presentation that is simple to understand and, therefore, effective in generating player excitement and enthusiasm. The result is a highly flexible value-aggregation process that can be easily adapted to any theme/brand while remaining easily understood by players. 
     Referring to  FIG.  1   , there is shown a gaming machine  10  similar to those operated in gaming establishments, such as casinos. With regard to the present invention, the gaming machine  10  may be any type of gaming terminal or machine and may have varying structures and methods of operation. For example, in some aspects, the gaming machine  10  is an electromechanical gaming terminal configured to play mechanical slots, whereas in other aspects, the gaming machine is an electronic gaming terminal configured to play a video casino game, such as slots, keno, poker, blackjack, roulette, craps, etc. The gaming machine  10  may take any suitable form, such as floor-standing models as shown, handheld mobile units, bartop models, workstation-type console models, etc. Further, the gaming machine  10  may be primarily dedicated for use in playing wagering games, or may include non-dedicated devices, such as mobile phones, personal digital assistants, personal computers, etc. Exemplary types of gaming machines are disclosed in U.S. Pat. Nos. 6,517,433, 8,057,303, and 8,226,459, which are incorporated herein by reference in their entireties. 
     The gaming machine  10  illustrated in  FIG.  1    comprises a gaming cabinet  12  that securely houses various input devices, output devices, input/output devices, internal electronic/electromechanical components, and wiring. The cabinet  12  includes exterior walls, interior walls and shelves for mounting the internal components and managing the wiring, and one or more front doors that are locked and require a physical or electronic key to gain access to the interior compartment of the cabinet  12  behind the locked door. The cabinet  12  forms an alcove  14  configured to store one or more beverages or personal items of a player. A notification mechanism  16 , such as a candle or tower light, is mounted to the top of the cabinet  12 . It flashes to alert an attendant that change is needed, a hand pay is requested, or there is a potential problem with the gaming machine  10 . 
     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&#39;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  FIG.  3   ). The physical item may, for example, be currency bills, coins, tickets, vouchers, coupons, cards, and/or computer-readable storage mediums. The deposited 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. In response to a cashout input that initiates a payout from the credit balance on the “credits” meter  84  (see  FIG.  3   ), the value output devices are used to dispense cash or credits from the gaming machine  10 . The credits may be exchanged for cash at, for example, a cashier or redemption station. Examples of value output devices include, but are not limited to, a coin hopper for dispensing coins or tokens, a bill dispenser, the card reader/writer  30 , the ticket dispenser  32  for printing tickets redeemable for cash or credits, a wireless communication interface for transmitting cash or credit data to a nearby mobile device, and a network interface for depositing cash or credits to a remote account via an electronic funds transfer. 
     Turning now to  FIG.  2   , there is shown a block diagram of the gaming-machine architecture. The gaming machine  10  includes game-logic circuitry  40  securely housed within a locked box inside the gaming cabinet  12  (see  FIG.  1   ). The game-logic circuitry  40  includes a central processing unit (CPU)  42  connected to a main memory  44  that comprises one or more memory devices. The CPU  42  includes any suitable processor(s), such as those made by Intel and AMD. By way of example, the CPU  42  includes a plurality of microprocessors including a master processor, a slave processor, and a secondary or parallel processor. Game-logic circuitry  40 , as used herein, comprises any combination of hardware, software, or firmware disposed in or outside of the gaming machine  10  that is configured to communicate with or control the transfer of data between the gaming machine  10  and a bus, another computer, processor, device, service, or network. The game-logic circuitry  40 , and more specifically the CPU  42 , comprises one or more controllers or processors and such one or more controllers or processors need not be disposed proximal to one another and may be located in different devices or in different locations. The game-logic circuitry  40 , and more specifically the main memory  44 , comprises one or more memory devices which need not be disposed proximal to one another and may be located in different devices or in different locations. The game-logic circuitry  40  is operable to execute all of the various gaming methods and other processes disclosed herein. The main memory  44  includes a wagering-game unit  46 . In one embodiment, the wagering-game unit  46  causes wagering games to be presented, such as video poker, video black jack, video slots, video lottery, etc., in whole or part. 
     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  FIG.  1   . The I/O bus  48  is also connected to a storage unit  56  and an external-system interface  58 , which is connected to external system(s)  60  (e.g., wagering-game networks). 
     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&#39;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  FIG.  2   . Any component of the gaming-machine architecture includes hardware, firmware, or tangible machine-readable storage media including instructions for performing the operations described herein. Machine-readable storage media includes any mechanism that stores information and provides the information in a form readable by a machine (e.g., gaming terminal, computer, etc.). For example, machine-readable storage media includes read only memory (ROM), random access memory (RAM), magnetic-disk storage media, optical storage media, flash memory, etc. 
     Referring now to  FIG.  3   , there is illustrated an image of a basic-game screen  80  adapted to be displayed on the primary display  18  or the secondary display  20 . The basic-game screen  80  portrays a plurality of simulated symbol-bearing reels  82 . Alternatively or additionally, the basic-game screen  80  portrays a plurality of mechanical reels or other video or mechanical presentation consistent with the game format and theme. The basic-game screen  80  also advantageously displays one or more game-session credit meters  84  and various touch screen buttons  86  adapted to be actuated by a player. A player can operate or interact with the wagering game using these touch screen buttons or other input devices such as the buttons  26  shown in  FIG.  1   . The game-logic circuitry  40  operates to execute a wagering-game program causing the primary display  18  or the secondary display  20  to display the wagering game. 
     In response to receiving an input indicative of a wager drawn on or deducted from 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 games 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 games 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  FIG.  1   , following receipt of an input from the player to initiate a wagering-game instance. The gaming machine  10  then communicates the wagering-game outcome to the player via one or more output devices (e.g., primary display  18  or secondary display  20 ) through the display of information such as, but not limited to, text, graphics, static images, moving images, etc., or any combination thereof. In accord with the method of conducting the wagering game, the game-logic circuitry  40  transforms a physical player input, such as a player&#39;s pressing of a “Spin Reels” touch key or button, into an electronic data signal indicative of an instruction relating to the wagering game (e.g., an electronic data signal bearing data on a wager amount). 
     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&#39;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). 
     Referring now to  FIG.  4   , there is shown a flowchart representing a data processing method  100  corresponding to at least some instructions stored and executed by the game-logic circuitry  40  in  FIG.  2    to perform operations according to one or more embodiments of the present concepts. The method  100  incorporates the use of value-bearing symbols presented by one or more display devices in communication with the game-logic circuitry  40 . Value-bearing symbols are symbols that include award indicia that visibly indicate an award value associated with the value-bearing symbol. The awards associated with the value-bearing symbols include at least the indicated award values, and awards associated with multiple value-bearing symbols may aggregated the award values of the value-bearing symbols together into an aggregated award value. The method  100  uses value-bearing symbols that are held or locked into the symbol array until either one or more award conditions are met or a counter associated with the value-bearing symbols has met a termination count or value. For example, the award condition may be to fill a column with value-bearing symbols, and if this condition is met, the values indicated by the value-bearing symbols within the column are awarded. However, if a counter (e.g., a spin or game cycle counter) associated with the column reaches a termination count prior to the award condition, then the value-bearing symbols are removed from the column. In other embodiments the method  100  includes additional, fewer, or alternative steps to be performed by the game-logic circuitry  40 , the display device, and/or another suitable device of the gaming system, including those steps and devices described elsewhere herein. 
     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 an array of symbol in the respective symbol positions. The array of symbol positions is arranged in a number of rows (e.g., three rows) by a number of columns (e.g., five columns). The symbol positions of the array may be allocated to one or more subsets for a value-bearing symbol feature described herein. In the example embodiment, each column defines a subset. In other embodiments, the subset may any other suitable grouping of symbol positions. Each subset is associated with a subset counter that is selectively initialized and terminated as described herein. At step  106 , a player enters play parameters such as a wager amount to be drawn from a credit balance (deducted from a credit meter) and number of lines or ways 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. At step  108 , in response to the player initiating the reel spin, the game-logic circuitry generates a random game outcome. At step  110 , the game-logic circuitry spins and stops the reels to land a plurality of symbols in the displayed array according to the selected game outcome. At step  112 , the game-logic circuitry provides awards for any winning symbol combinations (e.g., line pays and scatter pays) in the array. 
     At step  114 , the game-logic circuitry determines whether or not the landed plurality of symbols include any value-bearing symbols. If one or more value-bearing symbols are included within the landed plurality of symbols, the game-logic circuitry then locks any value-bearing symbols to the symbol array at step  116  such that the locked value-bearing symbols remain within the symbol array through one or more subsequent spins. Each value-bearing symbol may be locked to a symbol position, row, or column, such as the symbol position, row, or column in which the value-bearing symbol occupied as part of the landed plurality of symbols. 
     At step  118 , for subsets of the symbol array that did not include locked value-bearing symbols prior to the game outcome and are now occupied by one or more locked value-bearing symbols from step  116 , a respective subset counter is initialized. The respective subset counter is initialized to an initial count or value. In at least some embodiments, the initial count is predetermined. In other embodiments, the initial count may be variable according to one or more parameters (e.g., randomly generated values, wager amount, player history, etc.). In the example embodiment, the subset counters are configured to count spins or game outcomes. In other embodiments, the subset counters may be configured to count a different parameter of the game, such as a number of outcomes with or without a particular symbol. 
     At step  120 , the game-logic circuitry determines whether or not award conditions have been met for at least some of the locked value-bearing symbols. In the example embodiment, the award conditions include locking value-bearing symbols in every symbol position of a particular subset. In other embodiments, the award conditions may not require the entire subset be filled with value-bearing symbols, but rather a trigger amount of value-bearing symbols be reached. Additionally or alternatively, other suitable conditions within the symbol array may be incorporated within the award conditions. 
     At step  122 , if the award conditions have been met (i.e., the number of value-bearing symbols has reached the trigger amount), the values visually indicated on the locked value-bearing symbols associated with the award conditions are awarded and the associated value-bearing symbols are removed or unlocked from the symbol array. That is, the value-bearing symbols may be removed immediately to reveal an underlying symbol or a blank space in its place on the symbol array until another spin or game cycle of the game is conducted. Unlocking the value-bearing symbols may cause the value-bearing symbols to ‘spin’ with other symbols in the symbol array, thereby freeing the underlying symbol position for a new symbol (including a subsequent value-bearing symbol) to land within. In some embodiments, achieving the award conditions for one subset may result in every value-bearing symbol within the array being removed or unlocked. It is to be understood that the award conditions of each subset may be at least partially independent from each other such that the award conditions for multiple subsets may be met during the same game outcome. In such an outcome, awards for each winning subset may be provided simultaneously. 
     At step  124 , the game-logic circuitry adjusts any initialized subset counters (referred to herein as “active counters” or “active subset counters”) based on the game outcome. More specifically, the game-logic circuitry adjusts the active counters for at least three different states of the associated subset: (i) an award condition has been met; (ii) additional value-bearing symbols have been locked into the subset; and (iii) no new value-bearing symbols have been locked into the subset. A fourth state in which an inactive counter is initialized or activated is addressed by the step  118 , and no additional changes are made to the newly activated counter by the game-logic circuitry. 
     In the first state in which an award condition was met, the locked value-bearing symbols have been removed or unlocked from the symbol array and a corresponding award has been provided. As a result, the game-logic circuitry deactivates the subset counter associated with the subset that included the removed or unlocked symbols. The subset counter is reverted to an inactive state until a subsequent game outcome includes a value-bearing symbol within the associated subset, thereby initializing the subset counter at step  118 . 
     In the second state in which one or more additional value-bearing symbols have landed within a subset associated with an active subset counter, the subset counter is adjusted to, towards, or beyond the initial count. That is, the current count of the subset counter may be incremented or decremented towards the initial count, or the current count may be set to a predefined value (including being reset to the initial count). In the example embodiment, the count may be incremented or decremented by one. In certain embodiments, the count is incremented or decremented by a value other than one. This adjustment facilitates ‘streaks’ that perpetuates the feature in response to positive game outcomes that continue to approach the award conditions (i.e., accruing additional value-bearing symbols in a particular subset). 
     Other suitable mathematical operations may be used to adjust the counter as well. The adjustments may also be based on the current count and/or other conditions. For example, the amount by which the counter increases or decreases may be at least partially a function of the current count and/or a randomly generated value. In another example, each subset may have different adjustment configurations. In other embodiments, the subset counter may remain unchanged (i.e., the current count does not change) in the second state. It is to be understood that although the foregoing adjustments were described with respect to the second state, these adjustments may be equally applicable to other states resulting in the adjustment of the subset counters. 
     For the third state, in contrast to the second state, if no additional value-bearing symbols are detected in a subset, then the subset counter is adjusted away from the initial counter and towards a termination count. For example, if the initial count is three and the termination count is zero, the counter may be decremented by one for each spin or outcome in which no additional value-bearing symbols are detected in the subset. 
     At step  126 , in response to the subset counter adjustments of step  124 , the game-logic circuitry determines if any of the active subset counters have met a termination count. If the termination count has been met by a subset counter, the game-logic circuitry removes or unlocks any locked value-bearing symbols from the associated subset and deactivates the subset counter at step  128 . The aggregated value of the removed value-bearing symbols is not awarded at step  128 . That is, in the example embodiment, the aggregated value of the locked value-bearing symbols in a subset is only awarded in response to one or more award conditions being met for that particular subset (e.g., filling the subset with value-bearing symbols). In other embodiments, at least a portion the aggregated value may be stored (at least temporarily) in a register or other suitable game element as described in one of the foregoing embodiments to facilitate ‘redemption awards’ through additional game features. 
     The game-logic circuitry concludes the current game cycle at step  130  following either a determination at step  126  that no termination count has been met by any active subset counters or in response to step  128 . Subsequent game cycles may proceed according to at least some of the steps of the method  100 . It is to be understood that although the steps of the method  100  have be described in a particular order, other embodiments may include additional, fewer, or alternative steps and/or reorder the described steps  102 - 130 . For example, steps  114 - 128  may be reordered, and these steps may occur at any point between the outcome being generated at step  108  and concluding the game cycle at step  130 . 
       FIGS.  5 A- 5 F  depict an example game interface during play of a game implementing the game feature described in  FIG.  4   . More specifically,  FIG.  5 A  depicts the interface at a first game cycle outcome,  FIG.  5 B  depicts the interface at a second game cycle outcome,  FIG.  5 C  depicts the interface at a third game cycle outcome,  FIG.  5 D  depicts the interface at a fourth game cycle outcome,  FIG.  5 E  depicts the interface at a fifth game cycle outcome, and  FIG.  5 F  depicts the interface at a sixth game cycle outcome. The game cycles are ordered in chronological order such that the first game cycle precedes the second game cycle, which precedes the third game cycle, and so forth. 
     In each game cycle, a plurality of symbol-bearing reels is spun and stopped to land a plurality of symbols in a symbol array  200 . The illustrated array  200  has fifteen symbol positions arranged in three rows and five columns  202 ,  204 ,  206 ,  208 , and  210 . Each column is associated with a respective reel such that each stopped reel presents three symbols. Alternatively, each symbol position may be associated with a respective independent reel such that each stopped reel presents a single symbol. The array may have more or less rows and/or columns. The number of symbol positions in each column may vary from each other. For example, the number of symbol positions in each column may be progressively increased such that the first column  202  has less symbol positions than the fifth column  210  does. 
     In the example embodiment, the subsets described in  FIG.  4    are the columns  202 ,  204 ,  206 ,  208 , and  210  of the symbol array  200 . It is to be understood that the subsets may be defined alternatively as rows or other suitable combinations of symbol positions (including combinations that are not adjacent to each other). In certain embodiments, some of the symbol positions of the array  200  are not associated with any subset. For example, the first column  202  may not be a subset, and therefore value-bearing symbols either are not present within the reels of the first column  202  or are not locked to the first column to determine an award as described herein. 
     Referring to the first game cycle of  FIG.  5 A , the reels are spun and stopped to land a plurality of symbols in the array  200 . As shown in  FIG.  5 A , the landed plurality of symbols includes a value-bearing symbol V 9  in the second column  204 . Similar to the value-bearing symbols described above, the value-bearing symbol V 9  includes visual value indicia (e.g., a value presented in text) indicating a value associated with the value-bearing symbol V 9 . The value of the value-bearing symbol V 9  and other value-bearing symbols may be predefined, fixed values or dynamic values. For dynamic values, the value of each value-bearing symbol may be randomly determined and/or a function of one or more value parameters. The value parameters may include, but are not limited to, a wager amount, wager frequency, wager history, game history, player history, and/or other suitable parameters associated with the player and/or the game. In one example, as a player wagers more on each game cycle or spin, the potential value of the value-bearing symbols may increase. In certain embodiments, the identity of the particular column or subset may be a value parameter. For example, the second column  202  may include a lower average value for each value-bearing symbol relative to the average value of value-bearing symbols within the fifth column  210 . In certain embodiments, the value-bearing symbols are not limited to a value amount but may include value indicia indicating one or more progressive jackpots associated with the wagering game. That is, the value of the progressive jackpot may be awarded from a value-bearing symbol if the award conditions described herein at met. 
     In response to the value-bearing symbol V 9  landing in the second column  204 , a subset counter  212  is initialized for the second column  204 . In the example interface, none of the other columns have active subset counters, and the difference between active and inactive subset counters is visually denoted by the inactive subset counters between removed from the interface. However, in other embodiments, other suitable visual characters may be used to distinguish between active and inactive counters. For example, inactive counters may be greyed-out. The subset counter  212  may undergo a transition animation to depict the change from the inactive state to active. Such a transition animation may include other elements of the interface, such as the value-bearing symbol V 9  and/or the column  204 . 
     The subset counter  212  is initialized at an initial count of three. The counter  212  is configured to count game cycle outcomes and establishes a finite window for the player to achieve the award conditions associated with the second column  204 . The counter  212  includes a plurality of count indicators  214  that visually indicate the current count of the counter  212 . In the example embodiment, the count indicators  214  are a series of dots in which filled-in dots represent the current count (which is three in  FIG.  5 A ). Not only do these dots indicate the current count, but also how the current count relates to the termination count and the initial count. In other embodiments, other suitable indicators of the current count may be used, such as a text-based indicator. 
     The value-bearing symbol V 9  is locked into the symbol array  200  such that, for one or more subsequent game cycles, the value-bearing symbol V 9  occupies a symbol position irrespective of the underlying reels. That is, the locked value-bearing symbol V 9  may supersede an underlying symbol from the reels in the same position, or the reels may ignore or skip the symbol position. The value-bearing symbols may be locked into the symbol positions in which the value-bearing symbols landed in or other symbol positions within the symbol array  200 . For example, the value-bearing symbol V 9  may be locked to the second column  204  such that the value-bearing symbol V 9  may be moved to a different position within the second column  204 . This may be beneficial particularly in embodiments in which paylines and/or other features of the game may need certain rows or symbol positions unoccupied by value-bearing symbols to activate. The locking process may include one or more animations to indicate to the player that the value-bearing symbol has been locked. For example, a border or background may be added to the symbol position of the locked value-bearing symbol V 9  to visually distinguish the locked symbol position from other symbol positions. In another example, one or more visual characteristics (including any animation) of the value-bearing symbol V 9  may be changed to indicated that the value-bearing symbol V 9  has been locked. 
     With respect now to  FIG.  5 B , the second game cycle has been initiated to generate an outcome, and the symbol array  200  has been populated by a new set of symbols with the exception of the locked value-bearing symbol V 9 . In the second game cycle outcome, no additional value-bearing symbols have been detected in the second column  204 . As a result, the subset counter  212  is decremented by one, and the count indicator  214  has been updated to indicate that the current count is two. In other embodiments, different adjustments may be made to the current count of the subset counter  212  in response to no additional value-bearing symbols being detected in the second column  204 . For example, the initial count of the counter  212  may be zero or one, and the count is incremented instead of decremented. In another example, the counter  212  may be set at a value or count rather than applying arithmetic operations. The operations applied to the counter  212  may be linear (e.g., decrementing by one for each cycle without additional value-bearing symbols) or non-linear. Non-linear operations may be used, for example, in embodiments in which the count of the counter  212  is used to generate visual elements or animations like a graph for the indicator  214  or in embodiments in which the current count may have a functional relationship to one or more elements of the game, such as the value of the next value-bearing symbol. 
     In addition to the updated count of the column  212 , the fourth column  208  includes a value-bearing symbol V 10  in the second game cycle outcome. The value-bearing symbol V 10  is locked to the fourth column  208 , and a subset counter  216  associated with the fourth column  208  has been initialized similar to the subset counter  212  in the first game cycle outcome shown in  FIG.  5 A . As described herein, with respect to the value-bearing symbol feature, each column may be independent of the other columns. That is, the counter and award conditions are independent for each column. In other embodiments, value-bearing symbols, counters, and/or award conditions may be affected by the state of symbol positions of the array  200  outside of the associated column. For example, receiving an award for value-bearing symbols in one column may remove or unlock the value-bearing symbols in other columns. 
       FIG.  5 C  depicts the interface in response to an outcome being generated for the third game cycle. In the illustrated example, no additional value-bearing symbols landed in the symbol array  200 . As a result, the subset counters  212 ,  216  have been decremented to one and two, respectively. The respective count indicators  214  have been updated to visually indicate these adjustments to the counters  212 ,  216  to the player. 
     Following the third game cycle,  FIG.  5 D  depicts the outcome of the fourth game cycle succeeding the third game cycle. In the fourth game cycle, no additional value-bearing symbols have landed in the second column  204 , thereby failing to achieve the award conditions within the period of time defined by the subset counter  212 . As a result, the subset counter  212  has been decremented from one to zero. In the example embodiment, zero is the termination count for the counters. When the termination count is met by the counter  212 , the value-bearing symbol feature is reset for the column  204 . More specifically, the value-bearing symbol V 9  is removed from the symbol array  200  and the counter  212  is also deactivated as described further in detail below with respect to  FIG.  5 E . It is to be understood that, in this context, ‘removing’ the value-bearing symbol V 9  may include the removal of the value-bearing symbol prior to the next spin or game cycle or unlocking the value-bearing symbol V 9  such that the symbol position is available to receive a new symbol from the next spin. The value(s) of the removed value-bearing symbols from the second column  204  are not awarded in the example embodiment. In other embodiments, other suitable game features may facilitate retrieval of at least a portion of the aggregated value of the removed value-bearing symbols. 
     The fourth game cycle outcome also includes a new value-bearing symbol V 11  in the fourth column  208 . The value-bearing symbol V 11  is locked into the fourth column  208  and the subset counter  216  is reset to three (i.e., the initial count) as shown by the counter indicators  214  of the counter  216 . That is, in the example embodiment, the current count of an active subset counter is reset to three in response to one or more additional value-bearing symbols irrespective of whether the current count is one, two, or three. In other embodiments, the current count is incremented or remains the same rather than reset to the initial count or another predefined value. It is to be understood that different configurations of the counters (i.e., different initial counts, termination counts, and/or operations) may result in different specific operations applied to the current count of the subset counters. The general configuration of the example counters is that landing new value-bearing symbols causes the current count to move towards or to the initial count and away from the termination count, and vice versa for not landing any new value-bearing symbols. This general configuration incorporates ‘streak’ gameplay in which continually accruing positive outcomes (i.e., a “hot streak”) extend play of the game feature, while repeated misses (i.e., a “cold streak”) causes the game feature to end. In other embodiments, other suitable configurations of the counters may be used to regulate play of the game feature. 
     The fifth game cycle follows immediately after the fourth game cycle, and  FIG.  5 E  depicts the outcome of the fifth game cycle. As described with respect to  FIG.  5 D , the second column  204  did not achieve the award conditions of filling every symbol position in the column  204 . As a result, the value-bearing symbol V 9  was removed or unlocked from the symbol array  200  and the symbol position is populated with a new symbol (which may be another value-bearing symbol). The subset counter  212  shown in  FIGS.  5 A- 5 D  has been returned to an inactive state similar to the counters of the first, third, and fifth columns  202 ,  206 ,  210 . In the example embodiment, the subset counter  216  of the fourth column  208  is not affected by the subset counter  212  returning to the inactive state. The inactive state of the column  212  may persist at least until one or more triggering conditions (e.g., a new value-bearing symbol in the second column  204 ) are detected in subsequent game cycles. 
     In the fourth column  208 , an additional value-bearing symbol V 12  has landed, thereby filling every symbol position in the column  208  with a value-bearing symbol. In the example embodiment, the award conditions have been met for the fourth column  208 , and an award is provided. More specifically, the values indicated by the value indicia of the value-bearing symbols V 10 , V 11 , and V 12  are combined together as an aggregated award value. In some embodiments, if one or more of the value-bearing symbols includes a progressive jackpot indicia, the jackpot value may be combined with the other awarded values. 
     In addition to providing an aggregated award value, the value-bearing symbols V 10 , V 11 , and V 12  are removed or unlocked from the fourth column  208  for the next game cycle, and the subset counter  216  is set to an inactive state. This process is similar to the steps taken in response to a counter meeting the termination count. The difference between the two processes, in the example embodiment, being whether or not the values of the value-bearing symbols are awarded. 
       FIG.  5 F  depicts the outcome of the sixth game cycle following the fifth game cycle. The fourth column  208  has been reset as described above to await a new value-bearing symbol to activate the column time  216  (shown in  FIGS.  5 B- 5 E ) again. The fifth column  210  includes a new value-bearing symbol V 13 , and an associated subset counter  218  is activated similar to the subset counter  212  in  FIG.  5 A  and the subset counter  216  in  FIG.  5 B . Although only one or two subset counters have been active at a time in  FIGS.  5 A- 5 F , it is to be understood that any other suitable number of columns (including none and all of the columns) may have an active associated column timer on a given game cycle. In certain embodiments, a limitation may be placed on the number of columns having an active column timer on a given game cycle. 
     In at least some of the embodiments, the value-bearing symbols may be combined with additional value-bearing modifiers or symbols external to the symbol array. For example, an award symbol or graphical element having indicia associated with an award value may activate (e.g., visually appear or change to indicate the award symbol is active) in response to one or more award symbol conditions, which may include the trigger condition for awarding the value-bearing symbols within the symbol array. The award from these award symbols may be provided with the award from the associated value-bearing symbols or in response to a termination condition, such as a number of game cycles being met. Persisting the award symbol over multiple game cycles may facilitate additional features for building player excitement for an upcoming award. In certain embodiments, the indicia of the award symbol may be hidden from the player&#39;s view for one or more game cycles and is revealed prior to providing an award for the award symbol. Other suitable variations and additions of award symbols external to the symbol array are contemplated for incorporation with the embodiments described herein. 
       FIGS.  6 A- 6 D  depict an example game interface of a gaming machine with a symbol array  300  similar to the array  200  shown in  FIGS.  5 A- 5 F . More specifically,  FIGS.  6 A- 6 D  depict the game interface through an example game sequence including award symbols. The array  300  arranged in three rows and five columns  302 ,  304 ,  306 ,  308 , and  310 . In other embodiments, the array  300  may include a different number of rows and/or columns. In certain embodiments, the array  300  is not a parallelogram of symbol positions, but rather may be arranged in other suitable configurations, including a plurality of separate sets of the symbol positions. 
     In the example embodiment, a first state of the array  300  shown in  FIG.  6 A  is similar to the state shown in  FIG.  5 D , with a pair of active subset counters  312 ,  314  and a plurality of value-bearing symbols V 9 , V 10 , V 11 . In at least some embodiments, in addition to the subset counters  312 ,  314 , the game feature for providing awards from the value-bearing symbols may be limited in length by one or more other timers or counters. For example, the game feature described herein may be implemented as a bonus game feature that is active for a number of game cycles or rounds that may be free to the player (i.e., no wager or participation fee is required to initiate the game cycles of the bonus game feature). In another example, a periodic timer or counter may reset the array  300  after a number of game cycles or after a period of time, which may be predetermined or dynamic. These timers or counters may be used, for example, to conclude or reset the game feature and/or to provide awards for value-bearing symbols that have not met the trigger amount as described herein. 
     In the example embodiment, a second game state is shown in  FIG.  6 B . In the second game state, a game cycle after the first game state has occurred, and the fourth column  308  is populated with an additional value-bearing symbol V 12 . As a result, the trigger amount of value-bearing symbols for the fourth column is met, and the award values indicated by the value-bearing symbols V 10 , V 11 , and V 12  are to be awarded to the player. In the example embodiment, the trigger amount may also be an activation condition for an award symbol  316 . The award symbol  316  is associated with the fourth column  308  and is presented above the fourth column external to the symbol array  300 . That is, other award symbols may be activated independently for each remaining subset of the array  300  (i.e., the columns  302 ,  304 ,  306 ,  310 ). Other suitable presentations of the award symbol  316  (including presentations within the array  300 ) are contemplated by the present disclosure. 
     In certain embodiments, the award symbol  316  may be associated with a plurality of subsets or the array  300  as a whole. In other embodiments, the condition or conditions for activating the award symbol  316  may include additional or alternative parameters. In one example, a different number of value-bearing symbols may trigger the award symbol  316 , including a number of symbols over different subsets. The number of value-bearing symbols to generate the award symbol  316  may be referred to herein as an “award amount,” which may be the same as the trigger amount or a different amount (i.e., values greater than or less than the trigger amount). In another example, the trigger condition may include achieving a threshold wager amount, wager frequency, play time, and/or other suitable values in combination with a subset or the array  300  being populated with value-bearing symbols. 
     In the example embodiment, rather than immediately award the player based on the value-bearing symbols V 10 , V 11 , and V 12  in response to meeting the trigger amount, the value-bearing symbols V 10 , V 11 , and V 12  may persist in the array  300  with the award symbol  316  for one or more subsequent game cycles. That is, the game feature described herein with respect to the award symbol  316  may be active for a limited number of game cycles, wherein expiration of the limited number of game cycles may result in an award sequence for any remaining value-bearing symbols present within the array  300 , including value-bearing symbols in subsets that have not been met the trigger amount, and any award symbols. Other variations are contemplated herein, such as, and without limitation, the award sequence applying only to subsets having met the trigger amount, initiating the award sequence in response to other suitable termination conditions, and/or initiating awards sequences on a per-subset basis (i.e., award sequences for each subset may be independently initiated). 
     In the example embodiment, prior to the award sequence associated with the fourth column  308 , the award value associated with the award symbol  316  is visibly hidden while one or more subsequent game cycles continue. Hiding the value may increase excitement and anticipation, as the player knows an additional award will be provided at prior to conclusion of the game feature. In other embodiments, the award value may be presented immediately when initially presenting the award symbol  316 . In certain embodiments, rather than hiding the award value, the award symbol  316  may be animated to cycle through available award values. 
       FIG.  6 C  depicts a third game state at which a termination condition is detected. That is, as described above, the termination condition may include a predetermined number of game cycles being determined or presented. In other embodiments, another or additional termination conditions may be detected, such as the player initiating a card out sequence to conclude the gaming session. 
     In the example third state, the second column  304  includes two value-bearing symbols V 9 , V 13 , and the fourth column  308  includes the award symbol  316  and the three value-bearing symbols V 10 , V 11 , and V 12 . At the third state, a termination condition has been met (e.g., a number of game cycles have been completed), and an award sequence is initiated. For the award sequence, an award value A 1  is revealed on the award symbol  316 . In the example embodiment, every value-bearing symbol present in the array  300  at the third state is awarded to the player. That is, the award values of the value-bearing symbols V 9 -V 13  are provided in the award sequence. In other embodiments, only the value-bearing symbols V 10 -V 12  are awarded for reaching the trigger amount. 
     During the bonus game feature associated with the award symbol  316 , the subset counters may still be used to selectively remove value-bearing symbols from the array  300  prior to the award sequence. At the initiation of the award sequence, the subset counter may be given priority over or defer priority to the award sequence. That is, if a subset counter expires at the end of a game cycle that also initiates the award sequence, the associated value-bearing symbols may be removed prior to the award sequence (such that no award is provided for these symbols) or the award sequence may include the value-bearing symbols. 
       FIG.  6 D  depicts a fourth state following the third state during the award sequence. In the example embodiment, the value-bearing symbols may be removed from the array  300  to signify the aggregate award provided to the player. For example, each value-bearing symbol may be sequentially removed from the array  300  (e.g., left to right and top to bottom) as the associated award values are applied to a visible aggregate award value or credit balance presented by the display device of the gaming machine. In such an example, the value-bearing symbols may be animated to drop or fly off the array  300 . Other suitable animations and presentation elements may be used to convey the awarded values to the player. It is to be understood the order and sequence of animations may be adjusted to fit the presentation of the award sequence. For example, the award value A 1  of the award symbol  316  may be hidden until the award symbol  316  is animated to be removed from the interface during the award sequence. The award symbol  316  may be removed from the interface within, prior to, or after the sequence of removing the value-bearing symbols from the array  300 . 
     In at least some embodiments, the award symbol  316  may not be limited to a single award value. That is, at the original position of the award symbol  316  (or another suitable position within the interface), one or more subsequent award symbols  318  may be presented during the award sequence. The subsequent award symbols  318  include award indicia visibly identifying an award value A 2 . In the example embodiment, the subsequent award symbol  318  is revealed as the initial award symbol  316  is animated to be removed from the gaming interface and awarded to the player. As the subsequent award symbol  318  is then animated to be removed from the interface, another subsequent award symbol  318  with an award value A 3  may be presented. The subsequent award symbols  318  may be visibly identified by the player prior to presentation through additional presentation elements associated with the award symbol or alterations to the award symbol  316  (e.g., the color of the award symbol  316  changes). In one example, the subsequent award symbols  318  may appear ‘stacked’ to the player to indicate additional award symbols being present. 
     The number of award symbols  316 ,  318  presented during the award sequence may be randomly determined or a function of one or more parameters from play of the game. For example, the total number of value-bearing symbols within the array  300  and/or other indicia of the value-bearing symbols within the fourth column  308  may determine how many award symbols  316 ,  318  are provided. In certain embodiments, the determined number of award symbols  316 ,  318  may include at least one award symbol and up to a predefined maximum number of award symbols. In certain embodiments, the number of subsequent award symbols  318  is not determined on a per-symbol basis for each active award symbol  316 , but rather is determined for a plurality of award symbols. That is, a number of subsequent award symbols  318  may be distributed between one or more active award symbols  316  during the award sequence. 
     The award values (A 1 , A 2 , A 3 , . . . An) may be the same values or different values. Similar to the number of award symbols  316 ,  318 , the award values may be randomly determined (e.g., randomly selected from a weighted table of award values) and/or based on one or more parameters of the game. In certain embodiments, the award values may be divided between the number of award symbols from a total award value that may be at least partially randomly determined. It is to be understood that the award values and the values of the value-bearing symbols may be collectively considered an “aggregate award” provided during one or more award sequences without requiring the values being aggregated prior to being applied to the player&#39;s credit balance. That is, the awards may be provided individually or within subgroupings to adapt to the format of the award sequence or sequences of the game feature. 
     In at least some embodiments, after the award sequence is completed, the game may continue to a different game feature or reset the game feature associated with the award symbols. In one example, the game feature described in  FIGS.  4  and  5 A- 5 F  may be performed without the award symbols after the award sequence and until a trigger condition for the award symbol game feature is detected. In another example, a base game feature using the award symbols may commence, where the award symbol  316  may be awarded immediately in response to the associated subset meeting the trigger amount, no subsequent award symbols  318  are provided, and/or incomplete subsets are not awarded after a number of game cycles. In such an example, the award symbol feature described with respect to  FIGS.  6 A- 6 D  may represent a bonus or free spin game feature that is selectively triggered. In a further example, the game feature described above with respect to  FIGS.  6 A- 6 D  may be reset to continue for another plurality of game cycles. 
       FIGS.  7 A and  7 B  depict game interfaces with other embodiments of award symbols. The features described in  FIGS.  7 A and  7 B  may be incorporated with or replace the features described in  FIGS.  6 A- 6 D .  FIGS.  7 A and  7 B  depict an example symbol array  400  having a plurality of symbol positions organized into a plurality of columns  402 ,  404 ,  406 ,  408 , and  410  similar to the array  300  shown in  FIGS.  6 A- 6 D . In other embodiments, the game interface may include additional, fewer, or alternative elements, including those elements described elsewhere herein. 
     With respect to  FIG.  7 A , two subset counters  412 ,  414  are active for the second and fourth columns  404 ,  408 . Although no award condition has been met for any of the columns in the illustrated state, a set of award symbols  416  are presented above the symbol array. More specifically, each award symbol  416  is presented above a respective column  402 - 410  of the array  400 . In other embodiments, the award symbols  416  may be organized in a different configuration and/or associated with different subsets of symbol positions within the array  400 . For example, the award symbols  416  may instead be associated with a particular row of the array  400  rather than one of the columns  402 - 410 . In another example, each symbol position is associated with a color, background, or other visual characteristic linked to one of the award symbols  416  to define the subset. In a further example, the subsets associated with each award symbol  416  may overlap other subsets such that the functionality of the award symbols  416  described herein may be performed simultaneously with two award symbols  416 . In certain embodiments, the award symbols  416  are dynamic such that the associated subset of symbol positions (which may include all symbol positions) changes within the gaming session. For example, the award symbol  416  may move within the game interface to visually indicate the association with a new subset. 
     In the example embodiment, each award symbol  416  presents an award value (A 1 -A 5 ) through play of the game feature. The award value may change between game outcomes through one or more animations, such as flipping to a new value, spinning an underlying reel strip, or otherwise replace the old value with a new award value. In other embodiments, the award values remain fixed for a plurality of game outcomes. In one example, detecting a reset condition for the underlying subset of the array  400  causes the award value to change. In another example, awarding the award symbol  416  as described herein changes the award value. In a further example, the award value changes in response to changes to wager amount and/or frequency. The award values are selected from a range or set of available award values based at least partially on one or more random determinations by the game-logic circuitry. In other embodiments, the award values are predetermined. 
     In some embodiments, similar to the embodiments shown in  FIGS.  6 A- 6 D , the award values of the award symbols  416  are not presented until an award condition is triggered. That is, the award symbols  416  appear blank or otherwise obscure the award value until it is determined that the award value is to be provided to the player. The award condition and/or award sequence for the award symbols  416  may be the same or different from the award conditions and award sequence of  FIGS.  6 A- 6 D . In one example, the award condition is collecting a trigger amount of value-bearing symbols in the corresponding subset, and the award sequence reveals or otherwise presents the award value of the symbol as the award value is combined with the credit balance of the player. In another example, the game feature is a bonus game feature with a limited duration, and award sequence occurs at the end of the game feature if the corresponding award condition was achieved during the game feature. In a further example, the award condition is a random determination separate from populating the symbol array  400 , where one or more award symbols  416  are selected to be awarded. In yet another example, the award sequence for the award sequence may not cause the award value of the award symbol  416  to be directly awarded, but rather modifies the award value of one or more value-bearing symbols within the array  400  and/or adds a new value-bearing symbol to the array  400 , where the award value of the new value-bearing symbol is at least partially a function of the award value of the award symbol  416 . In another example, one or more award conditions (e.g., a combination of certain symbols within the array  400 ) cause a plurality of award symbols to be awarded together. 
     The award symbols  416  may be configured to provide a single award value or a plurality of award values in response to an associated award condition. That is, the award symbols  416  may be configured to function similar to the award symbols  316 ,  318  shown in  FIGS.  6 C  and  6 D, where a plurality of awards are provided. Each award may be presented as a separate award symbol  416  or as a plurality of awards originating from the same award symbol  416 . The number of awards and/or the amount of each award may be at least partially random or predetermined. In such embodiments, the number of awards can include one and up to a predetermined maximum number of awards. The value of each award may be scaled or otherwise based on the number of awards for the award symbol  416 . 
     In certain embodiments, the award symbols  416  include active and inactive symbols. Active award symbols  416  are eligible to be awarded or have already been award but await an award sequence (e.g., at the conclusion of the game feature). Inactive award symbols  416  are not eligible to be awarded such that even if the award condition of an inactive symbol  416  is triggered, the award of the inactive symbol  416  is not provided. The active and inactive award symbols  416  may be distinguishable based on visual characteristics. For example, the inactive symbols may appear transparent, greyed out, or altogether hidden from the game interface. The determination of active or inactive for each award symbol  416  may be based on, for example, player selection, random determination, the symbols within the array  400 , the wager amount and/or frequency of the player, the player account history, and/or other suitable parameters associated with the game feature. 
     The award symbols  416  may take any suitable form to provide the functionality described herein. Similarly, the award sequence or animation for providing the award values of the award symbols  416  may be adjusted according to the design and/or function of the game feature. For example,  FIG.  7 B  depicts award wheels  418  in place of the award symbols  416  shown in  FIG.  7 A . The award wheels  418  are segmented and each wheel segment includes a corresponding award value or jackpot value. In response to an award condition associated with one of the award wheels  418 , the wheel  418  and/or a corresponding selector (illustrated as an arrow pointing towards the wheel  418  in  FIG.  7 B ) are spun and stopped to select one of the wheel segments. The award value or jackpot value associated with the selected wheel segment is then provided as an award. In other embodiments, the selection may occur for each game outcome or several game outcomes such that the selected award is provided in response to achieving the corresponding award condition. In further embodiments, rather than depicting separate wheels for each subset of the array, the game interface may include a single award wheel  418  that selects the award value for any subsets achieving the award condition for a given game outcome. 
     Other suitable award presentation elements similar to the symbols and wheels shown in  FIGS.  6 A- 7 B  are contemplated as within the spirit and scope of the present disclosure. For example, one or more reel strips may be provided in place of the award symbols  416  in  FIG.  7 A , where the reel strips include award symbols  416  or award values that randomly populate award positions on the game interface. In other embodiments, the award condition triggers an award sequence with presentation elements that replace or obscure the symbol array to select one or more award values. In one example, the single award wheel  418  described above is presented over the array  400  in response to detecting an award condition, and one or more wheel segments are selected to provide the award value (or set of award values) associated with the award condition to the player. 
     In some embodiments, the features and functions described in the present disclosure are not limited to triggering based on value-bearing symbols. That is, other suitable trigger symbols (including symbols that are converted to value-bearing symbols as described herein) may be used in place of or in combination with the value-bearing symbols to initiate subset counter and trigger awards. For example, modifier trigger symbols may be used to modify the award value of one or more other value-bearing symbols. In another example, at least one type of trigger symbol has a hidden award value that is revealed and/or has a modifiable value that is updated in response to a modifier event as described herein. In a further example, at least one type of trigger symbol causes an award game feature to initiate (e.g., selecting a jackpot award or credit award from a segmented wheel). Accordingly, it is to be understood that the foregoing and following systems and methods may incorporate other trigger symbols where the use of value-bearing symbols is described herein. For example, the trigger symbols may be used within the method  100  (shown in  FIG.  4   ) in addition to or in place of the value-bearing symbols. 
       FIG.  8    is a flow diagram of an example method  500  for modifying, revealing, or otherwise update the award values associated with trigger symbols. That is, in response to a particular game event or conditions associated with the game feature, an award value associated with a trigger symbol is generated and/or updated. In at least some embodiments, the method  500  is integrated into a method similar to the method  100  shown in  FIG.  4    and conducted by a gaming machine. More specifically, the steps of the method  500  may be integrated through steps  114 - 128  of the method  100 . In other embodiments, the method  500  is integrated within another suitable game feature conducted by a gaming machine. The method  500  is at least partially performed by game-logic circuitry of the gaming machine in communication with one or more display devices to present the game feature associated with the method  500 . In other embodiments, the method  500  is at least partially performed by another suitable device and/or includes additional, fewer, or alternative steps, including those described elsewhere herein. 
     As mentioned above, the method  500  is integrated within a game feature. As a result, the method  500  begins in response to one or more new trigger symbols populating the symbol array from a game or spin outcome. At step  502 , the new trigger symbols are locked into the respective subsets and any associated subset counters are initiated or reset as described in the method  100 . If the number of trigger symbols in the subset reaches or exceeds a trigger amount, the trigger symbols are awarded as described in the method  100 . 
     In the example embodiment, at step  504 , the game-logic circuitry determines whether or not a modifier event associated with each trigger symbol is detected. A modifier event is an event, action, or outcome of the game feature that initiates the modifications of the associated trigger symbols as described herein. The modifier events may require certain other conditions to be met in addition to the events, such as meeting play time or wager thresholds, having a predetermined number of symbols in a subset, and the like. Each modifiable trigger symbol may be associated with a one or more unique modifier events and/or modifier events shared by other modifiable trigger symbols (e.g., the other trigger symbols in the same subset). 
     Modifier events may include, but are not limited to: (i) the associated trigger symbol populating the array, (ii) other certain symbols populating the subset of the associated trigger symbol, (iii) other certain symbols populating the symbol array (e.g., designated trigger symbols or symbols sharing characteristics of the associated trigger symbol), (iv) certain symbols (including other trigger symbols) populating a locked symbol position with a preexisting trigger symbol, (v) symbol positions associated with the symbol position being populated by the associated trigger symbol, (vi) symbols and/or other game elements external to the symbol array that are associated with the trigger symbol activating or otherwise linking to the trigger symbol, (vii) the associated trigger symbol populating a user-selected symbol position or subset, (viii) a particular combination of symbols populating the array, (ix) player selection of the associated trigger symbol, (x) the subset of the associated trigger symbol and/or another subset reaching the trigger amount (or another predetermined amount) of trigger symbols or a particular type of trigger symbols, and/or (xi) a trigger event for a bonus game feature or other game feature. Other suitable events that are detectable by the game-logic circuitry are considered to be within the spirit and scope of the modifier events described herein. 
     In the example embodiment, in response to detecting a modifier event associated with a trigger symbol, the game-logic circuitry causes the display device to adjust, reveal, or otherwise present an award value associated with the trigger symbol at step  506 . That is, in some embodiments, the trigger symbol is associated with an initial award value (e.g., a value-bearing symbol) that is modified or otherwise changed in response to the modifier event, and, in other embodiments, the award value is presented in an award sequence for the trigger symbol, which may include converting the trigger symbol to a value-bearing symbol, presenting another game element to provide the award, and/or other suitable presentation methods. Specific examples of the modifier events and the corresponding effects are described with respect to  FIGS.  9 A- 12    herein. 
     In other embodiments, the modifier event causes the award value of one or more other symbols to be changed or revealed. For example, a modifier event associated with a first trigger symbol in a first subset may affect the award values of one or more other trigger symbols populating the first subset. In such embodiments, the trigger symbol associated with the modifier event may include an award value, multiplier, and/or other suitable operator that impacts the change to the other trigger symbols. In certain embodiments, the changes to the symbols may not impact an award value of the symbol or has an indirect impact. In one example, a trigger symbol is modified to include additional functionality, such as a trigger for a bonus game feature. In another example, where symbol combinations determine awards for a given game outcome, the trigger symbol is upgraded to a higher-value symbol type. 
     It is to be understood that the award value presented in response to the modifier event is a new award value generated and/or revealed responsive to the modifier and is not the same as a previously presented award value of the trigger symbol unless the modifier event results in no change in award value. For example, a trigger symbol occupying a subset may not be increased in value unless another trigger symbol is present in the subset. 
     The changes to the trigger symbols and/or other symbols are presented by the display device through one or more presentation elements and/or animations. That is, the presentation elements and/or the animations enable the player to readily monitor and track the changes to available and/or provided award values. In some embodiments, modified or modifiable trigger symbols may be visually distinct from other trigger symbols. For example, certain trigger symbols do not present a respective award value until the associated modifier event is detected, and other trigger symbols are presented as value-bearing symbols throughout the game feature. 
     At step  508 , the game-logic circuitry proceeds with the game feature according to the steps of the method  100 . More specifically, the game-logic circuitry generates game outcomes and causes the display device to present the game outcomes while awaiting detection of award conditions, reset conditions, and/or termination conditions. In the example embodiment, the award conditions are reaching or exceeding a trigger amount of trigger symbols in a given subset of the array, the reset condition is a subset counter reaching a reset value (e.g., zero), and the termination condition is concluding a number of game outcomes, detecting a credit balance of zero, and/or detecting player initiation of a payout sequence. In other embodiments, the game-logic circuitry monitors other suitable conditions (including additional or alternative award, reset, and/or termination conditions). In certain embodiments, the award condition and/or the reset condition may be considered modifier events. For example, one trigger symbol may have a hidden award value that is revealed and/or generated in response to the associated award condition being met. Play of the game feature continues by generating new game outcomes until another game feature is initiated or a termination condition is met. 
       FIGS.  9 A- 9 D  depict a game interface including an example symbol array  600  for a game feature including modifier events. The symbol array  600  and the underlying game feature may be substantially similar to the arrays and game features shown in  FIGS.  5 A- 8   . In the example embodiment, the array  600  includes five columns  602 ,  604 ,  606 ,  608 , and  610 . In other embodiments, the game interface may have a different configuration and/or the game feature may include additional, fewer, or alternative functionality, including those described elsewhere herein. 
       FIG.  9 A  depicts the symbol array  600  at a first game outcome. In the first game outcome, a subset counter  612  for the second column  604  is initiated in response to a trigger symbol  614  populating the second column  604 . The trigger symbol  614  in this example is a value-bearing symbol having a value of ‘400’ and is locked into a symbol position of the second column  604  for one or more subsequent game outcomes. 
       FIG.  9 B  depicts the symbol array  600  at a second game outcome following the first game outcome shown in  FIG.  9 A . In the second game outcome, another trigger symbol  616  is locked into the second column  604  (thereby resetting the subset counter to the initial value of three), and a second subset counter  618  is initiated in response to locking a third trigger symbol  620  in the fourth column  608 . In the example embodiment, the values of each trigger symbol  614 ,  616 , and  620  are different. The first and third trigger symbols  614 ,  620  have values selected from a range or set of available award values, while the value of the second trigger symbol  616  is determined in response to a modifier event associated with the second trigger symbol  616 . 
     More specifically, the modifier event for the second trigger symbol  616  is the trigger symbol  616  populating a subset (i.e., column) having one or more preexisting or locked trigger symbols. In the example embodiment, the value of the second trigger symbol  616  is at least partially a function of the value of the first trigger symbol  614 . That is, the second trigger symbol  616  had an initial value of ‘100’ that is updated to include the value of the first trigger symbol. The resulting value of the second trigger symbol is ‘500’. The initial value of the second trigger symbol  616  may be used to ensure the second trigger symbol  616  has a corresponding award value even if no other trigger symbols are present in the subset or array. In other embodiments, the second trigger symbol  616  does not have an initial value, but rather is fully dependent on the values of the trigger symbols linked to the second trigger symbol  616  and the underlying mathematical operation(s). The “linked” trigger symbols may be all trigger symbols in the array, the trigger symbols in the same subset, trigger symbols sharing the same characteristic or type, trigger symbols occupying symbol positions sharing characteristics with the modifiable trigger symbol, and/or other suitable links between trigger symbols. In certain embodiments, the player may manually select trigger symbols to be linked together at least temporarily. 
     While the example provided with the first and second trigger symbols  614 ,  616  uses addition to generate the award value of the second trigger symbol  616 , other suitable mathematical operations may be used. For example, certain types of trigger symbols or combinations of trigger symbols may result in the values being multiplied and/or an additional award bonus being added to the final award value. 
     In certain embodiments, the value is not based on the award values of other symbols, but rather based on the number of locked trigger symbols. In such an embodiment, the award value may increase or decrease as the number of locked trigger symbols increases. The award value may be selected from a predetermined table of award values based on the number of locked trigger symbols in the array or subset. 
     The award value of the second trigger symbol  616  is presented in response to the modifier event such that the initial value of the second trigger symbol  616  is presented and then updated to the final award value, thereby enabling the player to recognize the change in value of the second trigger symbol  616 . In other embodiments, the initial value is not shown, and the second trigger symbol  616  is initially presented with the final award value of ‘500’. In further embodiments, the award value of the second trigger symbol  616  may not be revealed until an award condition associated with the second column  604  is detected. 
     In some embodiments, modifiable trigger symbols like the second trigger symbol  616  remain at the award value determined in response to the modifier event until the second trigger symbol  616  is removed from the array  600 . In other embodiments, the modifiable trigger symbols are updated again in response to new modifier events, such as a new trigger symbol occupying the subset and/or an “update symbols” populating the subset or array, where the update symbol causes the modifiable trigger symbols to reevaluate the respective award values based on the current state of the array  600 . The update symbols may be trigger symbols or other symbols that selectively populate the array  600 . 
     In certain embodiments, the modifier event includes a new symbol (e.g., a new trigger symbol) populating a locked symbol position of the array  600 . That is, while the locked trigger symbol persists in the corresponding symbol position, other symbols may selectively populate the locked position with the locked trigger symbol to activate a corresponding modifier event. The new symbols may include trigger symbols, symbols with multipliers, operators, and/or other suitable modifiers, and/or symbols that do not impact the game outcome (i.e., inactive symbols). In one example, the award value of the locked trigger symbol is modified at least partially as a function of the value, multiplier, operator, and/or other suitable modifier associated with the new symbol occupying the locked symbol position. The effect of overlapping symbols is not limited to the locked trigger symbol in at least some embodiments. For example, if a new trigger symbol populates a locked symbol position, the award value of the new trigger symbol may be applied to all locked trigger symbols in the corresponding subset. 
     In such embodiments with overlapping symbols, the locked symbols and/or the new symbols may be presented by the display device in a manner that enables the player to identify both symbols and/or the result of the overlapping symbols. For example, the display device may present one or more animations depicting the combination of values from the locked trigger symbol and the new overlapping symbol. In certain embodiments in which inactive symbols are included, the locked trigger symbols may fully or substantially obscure the inactive symbol. The inactive nature of such symbols may be temporary. That is, in unlocked symbol positions, these symbols may return to an active state and are incorporated within the game outcome and any winning outcome determination. This configuration may be used, for example, for embodiments including reel strips that span a plurality of symbol positions (e.g., a whole column), where the locked trigger symbol obscures one of the symbol positions associated with a given reel strip. 
       FIG.  9 C  depicts the game interface at a third game outcome following the second game outcome shown in  FIG.  9 B . At the third game outcome, a fourth trigger symbol  622  occupies the second column  604 , and an enhanced trigger symbol  624  occupies the fourth column  608 . In the example embodiment, the fourth trigger symbol  622  had an initial value of ‘200’. Like the third trigger symbol  616 , the modifier event for the fourth trigger symbol  622  is populating the array  600  with the fourth trigger symbol  622 , and the resulting action increases the award value of the fourth trigger symbol via aggregation. More specifically, the initial value of the fourth trigger symbol  622  is combined with the award values of the other two trigger symbols  614 ,  616  in the same subset to generate an aggregated award value of ‘1100’ as presented by the display device. The aggregation may be presented through one or more animations and/or presentation elements provided by the display device. 
     The enhanced trigger symbol  624  have additional or alternative modifier events and/or resulting actions in comparison to other trigger symbols  614 ,  616 ,  620 , and  624 . In the illustrated example, the enhanced trigger symbol  624  has no initial award value, but instead aggregates the values of all other trigger symbols locked into the array  600  irrespective of the subset or other affiliation between symbols or symbol positions. That is, the enhanced trigger symbol  624  has an aggregated award value from the award values of the trigger symbols  614 ,  616 , and  620 . In certain embodiments, multiple new trigger symbols landing on the same outcome may be processed sequentially (i.e., modifying and/or locking the new trigger symbols in order) such that the award value of fourth trigger symbol  622  is also aggregated within the value of the enhanced trigger symbol  624 . In other embodiments, the enhanced trigger symbol  624  has a different effect and/or different modifier event. Multiple types of enhanced trigger symbols  624  may be included in the game feature. In certain embodiments, the enhanced trigger symbol  624  may trigger the award condition without requiring the number of trigger symbols to reach the predetermined trigger amount. 
     In at least some embodiments, the enhanced trigger symbol  624  is visually distinct from the other trigger symbols. Although the illustrated embodiment depicts the enhanced trigger symbol  624  as a diamond and the other trigger symbols as circles or coins, it is to be understood that other suitable visual distinctions may be used. For example, the symbols may appear the same, but the symbol position of the enhanced trigger symbol  624  is visually distinct from the corresponding symbol positions of the other trigger symbols. In another example, the enhanced trigger symbol  624  has the same shape but a different color. In certain embodiments, the trigger symbols may be changed to or from enhanced trigger symbols in response to one or more game events, player input, random selection, and the like. 
       FIG.  9 D  depicts the game interface at a fourth game outcome following the third game outcome shown in  FIG.  9 C . At the fourth game outcome, the award values of the trigger symbols  614 ,  616 , and  622  have been provided to the player through one or more award sequences. That is, filling the second column  604  with trigger symbols activated the award condition for the second column  604 , and the award values of the trigger symbols  614 ,  616 , and  622  were provided as an award to the player (i.e., the award values are applied to the credit balance of the player). The trigger symbols  614 ,  616 , and  622  were removed from the array  600 , and the subset counter  612  of the second column  604  is also removed. Any new trigger symbols in the second column  604  reactivates the subset counter  612  as described in  FIG.  4   . 
     The fourth game outcome also includes a fifth trigger symbol  626  that populates the fourth column  608 . In this example, the fifth trigger symbol  626  is not modified by the other trigger symbols  620 ,  624 , but rather includes an award value of ‘250’ that is generated or selected by the game-logic circuitry. The fifth trigger symbol  626  and/or the corresponding symbol position may be a type of trigger symbol and/or symbol position, respectively, that do not include an associated modifier event. In other embodiments, the other trigger symbols locked in the subset or array  600  and/or the symbol position of the trigger symbol  626  prevent the modifier event from activating. That is, in such embodiments, the value or number of trigger symbols within the subset or array  600  have met or exceeded a threshold value such that subsequent trigger symbols remained unmodified. In further embodiments, activation of the modifier event associated with the fifth trigger symbol  626  is at least partially based on random determination by the game-logic circuitry. In some embodiments, the activation of modifier events is based on player selection, where the player is provided a limited number of opportunities to activate modifier events that occur within the game feature. In other embodiments, the fifth trigger symbol  626  has an active modifier event and aggregates the value of one or more other trigger symbols similar to the third and fourth trigger symbols  616 ,  622 . 
     As the enhanced trigger symbol  624  is still a trigger symbol, the trigger amount of the fourth column  608  has been met. An award sequence similar to the sequence provided between the third and fourth game outcomes for the second column  604  is presented for the fourth column  608  following the fourth game outcome. In some embodiments, the enhanced trigger symbol  624  may count as a plurality of trigger symbols towards the trigger amount. In the illustrated example, such an enhancement may result in the trigger amount for the fourth column  608  being achieved at the third game outcome rather than the fourth game outcome. The award values of the trigger symbols  620  and  624  would be awarded following the third game outcome (thereby removing these symbols from the fourth column  608 ), and the fifth trigger symbol  626  would reinitiate the subset counter  618  for the fourth column  608 . 
     The number of trigger symbols represented by the enhanced trigger symbol  624  may be randomly determined and/or based on one or more game events or conditions. In at least some embodiments, the modifier event associated with the enhanced trigger symbol  624  causes the enhanced trigger symbol  624  to “split” into a plurality of trigger symbols occupying a plurality of symbol positions, where the value of the split trigger symbols is at least partially based on the initial value of the enhanced trigger symbol  624 . For example, the split trigger symbols may be the same value as the initial value of the enhanced trigger symbol  624  or the initial value is evenly divided between the split trigger symbols. In another example, a multiplier and/or additional award is combined with the initial award value to generate the values of the split trigger symbols. In other embodiments, the award values of the split trigger symbols are predetermined and/or generated irrespective to the value of the enhanced trigger symbol  624  (e.g., the values are generated or selected in the same manner as other trigger symbols). In one example, at least some split trigger symbols have no award value or a predetermined award value. Trigger symbols with no award value may still be beneficial to increase the chance (or guarantee, depending on the functionality of the enhanced trigger symbol  624 ) of achieving the award condition. 
     The location of the split trigger symbols within the array  600  may be the same subset as the enhanced trigger symbol  624  and/or elsewhere within the array  600 . In one example, the split trigger symbols remain in the same subset to approach, meet, or exceed the trigger amount. In another example, at least some trigger symbols are split to occupy other subsets with active counters, such as a subset that is the closest to reaching the corresponding trigger amount of trigger symbols. In a further example, the split trigger symbols occupy symbol positions at least partially based on one or more random determinations. 
     In certain embodiments, in addition to or instead of splitting or duplicating, the enhanced trigger symbol  624  is configured to relocate and/or cause other symbols to relocate within the array  600 . In one example in which the enhanced trigger symbol  624  aggregates award values from locked trigger symbols in a subset, the enhanced trigger symbol  624  may be moved from an initial position in a subset with no locked trigger symbols to a subset with at least one locked trigger symbol, thereby ensuring the function of the enhanced trigger symbol  624  is maintained. In another example, the enhanced trigger symbol  624  may “pull” a locked trigger symbol from another subset to reach or approach the trigger amount in the subset of the enhanced trigger symbol. The triggers for the movement and/or splitting associated with the enhanced trigger symbol  624  may be the modifier events as described above or separate trigger events. In certain embodiments, the trigger events are the modifier events in combination with one or more other conditions of the game, such as the number of locked trigger symbols in each subset and the like. 
     It is to be understood that the functions of the trigger symbols and enhanced trigger symbols described above can be combined or isolated in any suitable configuration for the game features described herein. It is also to be understood that functionality tied to a particular trigger symbol may instead be tied to a particular subset or symbol position. For example, the functionality of the enhanced trigger symbol  624  over a regular trigger symbol may be imparted by the underlying symbol position rather than a specialized trigger symbol existing within the set of available symbols for populating the array  600 . These symbol positions with additional functionality may maintain the enhancements for one game outcome or a plurality of game outcomes (including the entire duration of the game). Removing and/or adding the enhancements to the symbol positions may be at least partially random, user selection, based on predetermined rules, and/or in response to one or more game events (e.g., after enhancing one trigger symbol, the enhancement is removed from a given symbol position). 
     In some embodiments, one or more trigger symbols have hidden or obscured award values that are presented in response to a modifier event, such as at the time an associated award condition is detected.  FIGS.  10 A and  10 B  depict an example game interface with a symbol array  700  for a game feature similar to the features described in  FIGS.  4 - 9 D . The game interface is presented by one or more display devices of a gaming machine in communication with game-logic circuitry. The array  700  includes five columns  702 ,  704 ,  706 ,  708 , and  710  and three rows of symbol positions. In other embodiments, the game interface includes additional, fewer, or alternative elements, including those described elsewhere herein. 
       FIG.  10 A  depicts the game interface at a first game outcome. In response to the first game outcome, the display device presents a subset counter  712  for the second column  704 . More specifically, the first game outcome includes a first trigger symbol  714  in the second column  704 , thereby initiating the subset counter  712  as described in  FIG.  4   . Unlike value-bearing trigger symbols, the first trigger symbol  714  does not include award indicia visually indicating an associated award. The first trigger symbol  714  may include no indicia, obscured indicia, a plurality of indicia, or combinations thereof (e.g., the form of the trigger symbol  714  changes in response to game events, conditions, and/or outcomes). For a plurality of indicia, the first trigger symbol  714  is not hidden, but rather the award value is not fixed and rotates through a plurality of award values (or presents the plurality of award values all at once). For example, the first trigger symbol  714  may be presented as a reel strip that spins through a plurality of available award values. In another example, the first trigger symbol  714  is a segmented wheel, where each segment represents an award value. In a further example, the first trigger symbol  714  appears the same as other value-bearing symbols (i.e., award indicia for a single award value), but cycles through a plurality of award values throughout the game feature. Other suitable presentations of the trigger symbols with hidden, obscured, and/or indeterminant award values are considered within the scope and spirit of the present disclosure. 
     In the example embodiment, the award value of the first trigger symbol  714  remains hidden until a corresponding modifier event is detected. The modifier event is detection of an award condition associated with the first trigger symbol  714  (i.e., meeting the trigger amount of trigger symbols in the second column  704 ). In other embodiments, other suitable modifier events may be used in addition to or in place of the award condition, such as detection of a new trigger symbol in the subset. 
       FIG.  10 B  depicts the game interface at a second game outcome that is subsequent to the first game outcome. In the second game outcome, the second column  704  includes two additional trigger symbols  716 ,  718 , and the fourth column  708  includes another trigger symbol  722  to initiate an associated subset counter  720 . In the example embodiment, filling the second column  704  with the trigger symbols  714 ,  716 ,  718  activates a corresponding award condition. The game-logic circuitry detects the award condition and triggers the modifier event for the first trigger symbol  714 , thereby causing the display device to present award indicia for the first trigger symbol  714 . 
     In some embodiments, the revealed award value is determined or generated in response to the modifier event. That is, no value is assigned to the first trigger symbol  714  until the first trigger symbol  714  is to be awarded to the player. In other embodiments, the award value is determined prior to the modifier event, such as during the selection of the first trigger symbol  714  from a set of available symbols for populating the array  700 . The revealed award value may be generated using the same rules, range, and/or set of values as the values of other symbols, or the value may be selected or generated through separate means. For example, the set of values or range of values for hidden award values may be at least partially different from the set or range associated with other trigger symbols. In another example in which award values are selected from a weighted table of award values, the hidden award values may be selected from a different table and/or having different weighting parameters on the available award values. In the illustrated example, the award value of the first trigger symbol  714  is selected from a set of award values including and/or favoring higher values in comparison to the set of award values for other trigger symbols. 
     In other embodiments, the award value is at least partially based on the award values, multipliers, and other game elements within the game interface. For example, the first trigger symbol  714  may include functionality similar to the trigger symbols of  FIGS.  9 A- 9 D  such that the award value of the first trigger symbol  714  includes at least the aggregate value of the other trigger symbols in the same subset. In another example, the first trigger symbol  714  reveals an operator, initial value, and/or multiplier that is combined with one or more award values on the game interface to generate the revealed award value of the first trigger symbol  714 . Other functions and/or configurations of trigger symbols with hidden award values are considered within the spirit and scope of the present disclosure, including functions and configurations described elsewhere herein. In one example, the modifier event may also cause the first trigger symbol  714  to move and/or generate additional trigger symbols to populate the array  700  as described above. 
     The presentation of the first trigger symbol  714  may include any suitable presentation configuration to convey to the player that revealed award value. That is, one or more animations and/or presentation elements (e.g., the symbol  714  itself) are presented in a manner that enables the player to readily identify the change to the first trigger symbol  714 . For example, if the first trigger symbol  714  is a wheel, reel strip, or other elements animated to cycle through a plurality of award values, the display device presents the first trigger symbol  714  “stopping” or otherwise focusing on the award value of the first trigger symbol  714 . In certain embodiments, the revealed award value is presented through an additional game feature or game element, such as an award or jackpot wheel. 
       FIGS.  11 A and  11 B  depict an example game interface similar to the interface shown in  FIGS.  10 A and  10 B . The game interface includes an array  800  with five columns  802 ,  804 ,  806 ,  808 , and  810 . The game interface is presented by one or more display devices of a gaming machine that are in communication with game-logic circuitry. In other embodiments, the game interface includes additional, fewer, or alternative presentation and/or game elements, including those described elsewhere herein. 
       FIG.  11 A  depicts the game interface a first game outcome similar to the first game outcome shown in  FIG.  10 A . More specifically, the second column  804  is populated by a first trigger symbol  814 , which causes a subset counter  812  to be initiated for the second column  804 . Like the first trigger symbol  614  shown in  FIG.  10 A , the first trigger symbol  814  does not initially include award indicia for an award value. Rather, the first trigger symbol  814  includes indicia indicating other functionality associated with the trigger symbol  814 . In the illustrated example, the first trigger symbol  814  includes the indicia of ‘JW’ to indicate the first trigger symbol  814  is associated with a jackpot wheel feature as described herein. Other suitable game features may be used with the first trigger symbol in addition to or instead of the jackpot wheel feature. For example, and without limitation, a bingo feature game, a picking feature game, roulette feature game, slot feature game, and the like may be associated with trigger symbols as describe herein. 
     The association between the first trigger symbol  814  and a game feature is not limited to indicia, but rather may include other suitable visual indicators (e.g., background, symbol type, etc.) to indicate the association. In some embodiments, the symbol position rather than the trigger symbol  814  is associated with the jackpot wheel feature such that the trigger conditions for the jackpot wheel feature include the associated symbol position or positions being occupied by trigger symbols. In certain embodiments, the first trigger symbol  814  includes award indicia to function the same as other value-bearing trigger symbols while maintaining the trigger functionality for the jackpot wheel feature. 
     In the example embodiment, the modifier event associated with the first trigger symbol  814  triggers the jackpot wheel feature. That is, reaching or exceeding the trigger amount of trigger symbols in the subset of the first trigger symbol  814  (i.e., the second column  804 ) causes the jackpot wheel feature to be initiated. In some embodiments, the award values for other trigger symbols in the subset are provided prior to the jackpot wheel presentation. In other embodiments, the award values are provided during and/or following the jackpot wheel presentation. In certain embodiments, the award values of the other trigger symbols are incorporated into the jackpot wheel feature (or other triggered game feature). For example, the jackpot wheel feature may include the award values of other trigger symbols and/or modify the award values of the other trigger symbols. In other embodiments, the trigger event for the jackpot wheel feature may be at least partially different from the modifier event. For example, the trigger event may include detecting a plurality of modifier events associated with symbols similar to the first trigger symbol  814  over one or more spins. 
       FIG.  11 B  depicts the game interface following a second game outcome subsequent to the first game outcome. In the second game outcome, the modifier event associated with the first trigger symbol  814  is detected. That is, the second column  804  is filled with trigger symbols. This modifier event in turn activates the jackpot wheel feature to generate or reveal an award value associated with the first trigger symbol  814 . 
     In the example embodiment, a jackpot wheel  816  is presented over the array  800 . The jackpot wheel  816  includes a plurality of wheel segments  818  associated with respective awards and segment selector  820  that visually indicates a selected segment from the wheel  816  as described herein. In other embodiments, the jackpot wheel  816  and/or the game interface have a different suitable configuration for the functions described herein. In one example, the jackpot wheel  816  is not presented over the array  800 , but rather is presented elsewhere on the game interface such that the array  800  remains in view (thereby enabling the underlying game feature and/or the award sequence to continue). In another example, the segment selector  820  is presented within the boundary of the wheel  816 . 
     In the illustrated embodiment, the jackpot wheel  816  includes a plurality of jackpot awards, where the indicia shown (“GRAND,” “MAJOR,” “MINOR,” and “MINI”) represent different jackpots. The jackpot awards may be progressive awards that are incrementally funded through wagers and/or other fund inputs or fixed, predetermined jackpots. In other embodiments, the jackpot wheel  816  includes a different number of jackpot awards and/or other jackpot award configurations. In some embodiments, the jackpot wheel  816  includes credit awards in addition to or in place of the jackpot awards. In such embodiments, the credit awards may be predetermined or based on the state of the array  800 . Other suitable awards, such as modifiers to be applied to other awards (e.g., the award values of the other trigger symbols to be awarded) may be included within the jackpot wheel  816 . Although the segments  818  shown in  FIG.  11 B  are all substantially the same size, other embodiments include segments  818  of different sizes. The difference in size between segments  818  may be directly tied to the probabilities of selecting each segment such that the player can visualize the odds of selecting a particular segment  818 . In other embodiments, the visual sizes of the segments  818  are not directly related to the underlying probabilities. 
     The display device is configured to animate the jackpot wheel  816  and/or the segment selector  820  through one or more spinning animations and then stopping on a wheel segment  818  randomly selected by the game-logic circuitry. The award associated with the selected wheel segment  818  (and, by extension, the trigger symbol  814 ) is provided to the player through an award sequence presented by the display device. The award sequence may be dedicated to the jackpot wheel  816 , or the award sequence may be shared with other awards provided through the game feature (e.g., the awards of any value-bearing trigger symbols). 
     In at least some embodiments with the jackpot wheel  816 , a plurality of trigger symbols  814  can be locked into the array  800  such that a plurality of modifier events associated with the jackpot wheel feature are activated simultaneously. In such embodiments, the jackpot wheel  816  may persist for a plurality of spins based on the number of modifier events detected that are associated with the wheel  816 . In one example, the number of spins matches the number of modifier events (which may correspond to an equal number of trigger symbols like the trigger symbol  814  being awarded). In another example, each additional modifier event scales the number of spins, where the number of spins is greater than the number of corresponding modifier events. Between spins of the jackpot wheel  816 , the wheel segments  818  may change to include additional or alternative awards, remove previously selected awards, and the like. In other embodiments, a new jackpot wheel  816  is presented for each respective modifier event associated with the jackpot wheel feature. These jackpot wheels  816  may be presented simultaneously, sequentially, and/or in other suitable configurations. 
       FIG.  12    depicts a game interface of an example game feature utilizing player selection with the functionality described in the present disclosure. The game interface is presented by one or more display devices of a gaming machine that are in communication with game-logic circuitry. The game interface, similar to other game interfaces described above, includes a symbol array  900 . Unless otherwise explicitly stated, the functionality and/or presentation of the game feature shown in  FIG.  12    is similar to the functionality and/or presentation of the game features described above with respect to  FIGS.  4 - 11 B . In other embodiments, the game interface includes additional, fewer, or alternative elements that may alter the functionality and/or presentation of the game feature, including those elements described elsewhere herein. 
     In the example embodiments, the game feature includes a user or player selection function to modify or otherwise affect the awards or potential awards associated with the game feature. That is, in response to one or more modifier events, the game interface includes a plurality of player selectable options  920  and prompts the player to select one or more of the options  920 . It is to be understood that although the options are shown in  FIG.  12    above the array  900 , the player selectable options  920  may be positioned elsewhere and/or presented in a different suitable configuration. In one example, the player selectable options are presented by a touchscreen of the gaming machine that functions as an input device of the gaming machine. 
     The player selectable options  920  are selectable in response to one or more modifier events. In one example, the modifier event is meeting or exceeding a trigger amount for a subset of the array  900 . In the illustrated interface, a fourth column  908  of the array  900  is filled with value-bearing symbols  914 , and the game-logic circuitry detects this state as a modifier event to trigger the player selection feature. In such examples, at least some of the selections by the player may apply only to the value-bearing symbols  914  within the fourth column  908 . In other examples, the modifier event is detection of a particular symbol in the array  900  or detecting the conclusion of predetermined number of free spins or game outcomes. In other embodiments, the modifier event may be any suitable game state or condition that is detectable from the current aspects of the game, including aspects not shown in the illustrated embodiment. For example, the modifier event may be based on a different symbol type, a combination of symbols having different types, and/or other suitable events or conditions that one of ordinary skill in the art would recognize as based on the game feature. 
     The player selections described herein may apply to one, some (e.g., a particular subset), or all value-bearing symbols  914  and/or symbol positions in the array  900 . The determination of which symbols and/or positions are affected by the player selection may be at least partially random, which symbols and/or symbol positions are associated with the modifier event, the type of selected option  920  (i.e., different options have different scopes of effect), and the like. In some embodiments, one or more game elements external to the player options  920  and the symbols determine the scope of the effect of the selected option  920 . For example, an indicator (e.g., an arrow) external to the array  900  may identify one or more symbol positions to be affect, or one or more symbol positions are designated randomly (e.g., which may be visually indicated through a change in color, background, framing, etc.) to receive the effect of the selected option  920 . In certain embodiments, the player selections may include other suitable enhancements, awards, and the like, such as awarding additional value-bearing symbols  914 . 
     In at least some embodiments, the player selectable options are presented having a hidden, obscured, or otherwise indeterminant effect. In the example embodiment, the player selectable options are initially presented as hidden options  922 . In response the player selecting a particular option, the display device is configured to reveal the corresponding modifier or effect. Several other examples states of the player options are shown in  FIG.  12   . The player option  924  includes a credit value of ‘300.’ This credit value may be applied to all, some, or one value-bearing symbol  914  associated with the player selection. For example, if the player selection is associated with the value-bearing symbols  914  of the fourth column  908 , the value of each symbol may be increased by ‘300’ in response to the selection of the option  924 . The credit value may be applied randomly to one or more value-bearing symbols. In another example, the award values of all new value-bearing symbols  914  populating the array  900  for at least one or more game outcomes following the selection are increased by the selected award value. 
     In certain embodiments, rather than applying the value to other symbols, the credit value is combined with other awards of the player. For example, the modifier event triggering the player selection may also be the award condition (e.g., for the fourth column  908 ) such that an award sequence is guaranteed for one or more awards. The credit award of the option  924  is then combined with the other awards of the award sequence. In further embodiments, the credit value may replace the credit value of one or more value-bearing symbols  914  and/or add additional value-bearing symbols  914  to the array  900 . In one example, the selection causes all value-bearing symbols  914  with an award value below the selected value to be increased to the selected value, thereby establishing an award value floor. In another example, the selection adds a value-bearing symbol  914  with the selected value to a subset approaching the respective trigger amount of trigger symbols (e.g., the value-bearing symbols  914 ). Other suitable means and/or configurations of applying the credit value to value-bearing symbols  914  and/or other game elements of the game feature are considered to be within the spirit and scope of the present disclosure, including those means described elsewhere herein. 
     Another player selectable option  926  includes a ‘2×’ multiplier, where one or more values are applied to multiplier to increase the resulting value. Similar to the credit value of the option  924 , the multiplier option  926  is applicable to all, some, or one of the value-bearing symbols  914  and/or other suitable values within the game feature, such as the credit value of other selected options  924 . In some embodiments, the multiplier may be applied to unselected options  920 . The multiplier is not limited to a purely numerical multiplication. That is, other suitable mathematical operations (which may include multiplication) may be used. For example, the option  926  may instead cause a plurality of award values from value-bearing symbols  914  to be aggregated together as an additional award or to replace the initial value of a given value-bearing symbol  914 . 
     Other suitable options and modifiers included within the player selectable options  920  are considered to be within the spirit and scope of the present disclosure, including those options and modifiers described elsewhere herein. In one example, jackpot awards associated with one or more player options. That is, selection of the jackpot option either awards a jackpot or increases progression towards a jackpot award (e.g., collecting three jackpot options provides a jackpot award or a jackpot symbol is added to the array  900  similar to  FIGS.  11 A- 11 B ). In another example, the options  920  include options for increasing or decreasing a number of free spins, a number of player selections, and/or a number of player selectable options  920 . In a further example, one or more options  920  may change the set or range of available award values for subsequent value-bearing symbols  914  that occupy a particular symbol position or subset. That is, the subsequent value-bearing symbol  914  may be increased in value indirectly from the selected option. In another example, one or more options  920  apply effects or modifiers to a particular symbol position, group of symbol positions (including the subsets), or to the array  900  as a whole. 
     Following selection of an option  920 , the selected option  920  is presented and the corresponding modification or other effect is applied to the game feature. The application of the modification or effect may be visually conveyed through one or more presentation elements and/or animations. For example, changes to the award values of value-bearing symbols  914  are reflected by updating the respective award indicia. The selected option  920  is then replaced by a new hidden option  922  or is transitioned to an inactive option  928  that is not selectable by the player for subsequent selections. The inactive option  928  may appear greyed out or otherwise unavailable in some embodiments. In other embodiments, the selected option  920  is simply removed from the interface, which may cause the remaining options  920  to be reorganized within the interface. For embodiments with no persistence between player selections, all the player selectable options are removed from the interface or transitioned to inactive until a new modifier event associated with player selection is detected. 
     In certain embodiments, the functionality described above may not rely on player input, but rather automatically selects and applies the modifications and effects of the player selectable options  920 . That is, the game-logic circuitry is configured to randomly select one or more of the player selectable options  920  to proceed through the game feature. In certain embodiments, the selection alternates between player selection and automatic selection. In some of these embodiments, the game-logic circuitry determines whether the selection is automatic or manual in response to one or more game events or conditions and/or based on one or more random determinations. For example, the game-logic circuitry may be configured to randomly select between automatic and manual selection with one or more weighting parameters impacted by the wager, game, and/or player history associated with the gaming session and/or the player. 
     In the embodiments disclosed herein, each value-bearing symbol may be assigned a credit value that is displayed upon the symbol. The credit value may, for example, range from a minimum credit value to a maximum credit value and be based on the total amount wagered on the game. For example, if a player wagers a minimum of 100 credits, the assigned credit value may range from 100 to 1000 credits. And if a player wagers a maximum of 500 credits, the assigned credit value may proportionately increase and thereby range from 500 to 5000 credits. In some embodiments, the assigned value may be randomly selected from a list of possible multipliers of the total amount wagered on the game, for example, 1×, 2×, 3×, 4×, 5×, 10×, 15×, 20×, 50×, and 100×. In other embodiments, the value may be pre-assigned to each value-bearing symbol as part of the reel strip layouts of the game reels. In still other embodiments, the assigned value may be randomly selected before, during, or at the conclusion of a reel spin. 
     As disclosed in the embodiments herein, awards may be provided for each game outcome based on at least the remaining symbols. For example, line pays and scatter pays may be awarded for each game cycle outcome based on the symbols populating the symbol array. In some embodiments, the value-bearing symbols may not be associated with awards outside of the features described herein. In other embodiments, the value-bearing symbols may be included within line pays, scatter pays, and/or other suitable awards. For example, the value-bearing symbols may be treated as a special symbol, such as a wild symbol. 
     While the embodiments are largely described within the context of a base game, it is equally contemplated that the disclosed embodiments can be practiced within the context of a free game bonus without a wager between free game cycles. 
     The embodiments of the present invention provide an innovative procedure for aggregating and adjusting values of symbols in a symbol array. Game-logic circuitry executing instructions in accordance with the embodiments present a visual display of spinning reels with clearly enumerated symbology that combine in readily understood arrangements to increase in value. An observer experiences excitement and anticipation as new symbols land in the array and aggregate values are summed and displayed. In stark contrast to conventional reel-spinning games in which symbol images are evaluated for winning combinations by paytable rules, the disclosed embodiments provide immediately recognizable values in WYSIWYG display configurations while adding variability as to how the values to be awarded to the player are selected and accumulated. 
     The value-aggregation and value-alteration procedure may be symbol- and game-agnostic. Themes and imagery of symbols and environment may be varied with no effect on the value-aggregation process. Or, if so desired, the criteria for value-aggregation may be modified in innumerable ways to produce new visual/animation effects and exciting summation sequences. 
     Further benefits are realized in increased computer processing efficiency, fewer rules to be evaluated, and simpler graphical representations. For example, in a conventional paytable evaluation, overlapping payline sections require multiple evaluation steps. Often, analysis is required to determine which payline results in the highest credit total, with the lesser value paylines being discarded but only after being evaluated—all this adds to processing overhead. Special symbols like wilds, multipliers, and scatter symbols can modify paytable values and may require separate, additional evaluation according to customized rule sets. All these procedures can be inherently more complex than simple aggregation (i.e., addition) and alteration of number values. The embodiments disclosed herein represents a win-win: simpler, almost self-explanatory graphics combined with faster, more efficient processing. The inventive value-aggregation procedure can be implemented on the vast majority of casino gaming machines without requiring upgrades or modifications. 
     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.
