COPYRIGHT NOTICE
A portion of the disclosure of this patent document contains or may contain material that is subject to copyright protection. The copyright owner has no objection to the photocopy reproduction by anyone of the patent document or the patent disclosure in exactly the form it appears in the Patent and Trademark Office patent file or records, but otherwise reserves all copyright rights whatsoever.
BACKGROUND
Gaming systems that provide players awards in primary or base games are well known. These gaming systems generally require a player to place a wager to activate a play of the primary game. For many of these gaming systems, any award provided to a player for a wagered-on play of a primary game is based on the player obtaining a winning symbol or a winning symbol combination and on an amount of the wager (e.g., the higher the amount of the wager, the higher the award). Winning symbols or winning symbol combinations that are less likely to occur typically result in larger awards being provided when they do occur.
For such known gaming systems, an amount of a wager placed on a primary game by a player may vary. For instance, a gaming system may enable a player to wager a minimum quantity of credits, such as one credit (e.g., in monetary currency, one penny, nickel, dime, quarter, or dollar; in non-monetary currency, one point, credit, coin, token, free play credit, or virtual buck), up to a maximum quantity of credits, such as five credits. The gaming system may enable the player to place this wager a single time or multiple times for a single play of the primary game. For instance, a gaming system configured to operate a slot game may have one or more paylines, and the gaming system may enable a player to place a wager on each of the paylines for a single play of the slot game. Thus, it is known that a gaming system, such as one configured to operate a slot game, may enable players to place wagers of substantially different amounts on each play of a primary game. For example, the amounts of the wagers may range from one credit up to 125 credits (e.g., five credits on each of twenty-five separate paylines). This is also true for other wagering games, such as video draw poker, in which players can place wagers of one or more credits on each hand, and in which multiple hands can be played simultaneously. Accordingly, it should be appreciated that different players play at substantially different wager amounts or levels and substantially different rates of play.
Bonus or secondary games are also known in gaming systems. Such gaming systems usually provide an award to a player for a play of one such bonus game in addition to any awards provided for any plays of any primary games. Bonus games usually do not require an additional wager to be placed by the player to be initiated. Bonus games are typically initiated or triggered upon an occurrence of a designated triggering symbol or designated triggering symbol combination in the primary game. For instance, a gaming system may initiate or trigger a bonus game when a bonus symbol occurs on the payline on the third reel of a three reel slot machine. The gaming systems generally indicates when a bonus game is initiated or triggered through one or more visual and/or audio output devices, such as the reels, lights, speakers, display screens, etc. Part of the enjoyment and excitement of playing certain gaming systems is the initiation or triggering of a bonus game, even before the player knows an amount of a bonus award won via the bonus game.
Various players continually seek out new and different variations to gaming systems. A continuing need thus exists for gaming systems and methods that provide new, exciting, and engaging games.
SUMMARY
Various embodiments of the present disclosure provide a gaming system and method providing a slot game including a symbol replacement feature. Generally, in various embodiments, the slot game employs a plurality of different symbols, each of which is included in one of a plurality of different groups. Each group includes at least two different symbols. In operation of these embodiments, the gaming system displays a plurality of the symbols and, if a triggering event associated with one of the groups occurs, the gaming system provides the symbol replacement feature by replacing at least one displayed symbol of that group with a different one of the symbols of that group. Thus, when providing the symbol replacement feature in these embodiments, the gaming system of the present disclosure replaces certain displayed symbols included in a particular group with different symbols included in that particular group and not with any symbols included in any other groups.
More specifically, in operation of one embodiment, for a play of the slot game, the gaming system displays a plurality of symbol display areas. For each of the plurality of symbol display areas, the gaming system randomly determines one of a set of a plurality of different symbols and displays that randomly determined symbol at that symbol display area, such as by displaying a plurality of reels spinning and stopping in association with the symbol display areas. In this embodiment, for each symbol of the set of symbols, that symbol is included in one of a plurality of different groups of the symbols. Additionally, in this embodiment, each group of the symbols includes at least two different symbols of the set of symbols. If a triggering event associated with one of the groups of the symbols occurs, for each of at least one displayed symbol in that group of the symbols, the gaming system replaces that displayed symbol with a different one of the symbols in that group of the symbols. The gaming system determines any awards associated with the displayed symbols, and displays any determined awards.
In one embodiment, a first one of the groups of the symbols includes a first symbol having a first value and a second symbol having a second value that is lower than the first value. In this embodiment, if a first triggering event associated with the first one of the groups occurs and at least one of the second symbols is displayed, for each displayed second symbol, the gaming system replaces that displayed second symbol with the first symbol having the higher first value. Thus, in this embodiment, the gaming system employs the symbol replacement feature to replace relatively low-value displayed symbols of a particular group with relatively high-value displayed symbols of that same particular group.
It should thus be appreciated that the gaming system and method of the present disclosure provide a new game to increase player engagement, enjoyment, entertainment, and excitement.
Additional features and advantages are described herein, and will be apparent from, the following Detailed Description and the Figures.

DETAILED DESCRIPTION
Slot Game Including a Symbol Replacement Feature
Various embodiments of the present disclosure provide a gaming system and method providing a slot game including a symbol replacement feature. Generally, in various embodiments, the slot game employs a plurality of different symbols, each of which is included in one of a plurality of different groups. Each group includes at least two different symbols. In operation of these embodiments, the gaming system displays a plurality of the symbols and, if a triggering event associated with one of the groups occurs, the gaming system provides the symbol replacement feature by replacing at least one displayed symbol of that group with a different one of the symbols of that group. Thus, when providing the symbol replacement feature in these embodiments, the gaming system of the present disclosure replaces certain displayed symbols included in a particular group with different symbols included in that particular group and not with any symbols included in any other groups.
Although the slot game is described as a primary wagering game in the embodiments described herein, it should be appreciated that the slot game of the present disclosure may additionally or alternatively be implemented as a bonus or secondary game. Further, while any credit balances, any wagers, and any awards are displayed as amounts of monetary currency or credits, one or more of such credit balances, such wagers, and such awards may be for any suitable non-monetary credits or currency, such as promotional credits and/or player tracking points or credits.
FIG. 1 illustrates a flowchart of an example process or method 100 of operating one embodiment of the gaming system of the present disclosure. In various embodiments, the process 100 is represented by a set of instructions stored in one or more memories and executed by one or more processors. Although the process 100 is described with reference to the flowchart shown in FIG. 1, it should be appreciated that many other processes of performing the acts associated with this illustrated process 100 may be employed. For example, the order of certain of the illustrated blocks and/or diamonds may be changed, certain of the illustrated blocks and/or diamonds may be optional, and/or certain of the illustrated blocks and/or diamonds may not be employed.
In operation of this example embodiment, the process 100 begins upon initiation of a play of the slot game including the symbol replacement feature. The gaming system displays a plurality of symbol display areas, as indicated by block 102. For each of the plurality of symbol display areas, the gaming system randomly determines one of a set of a plurality of different symbols and displays that randomly determined symbol at that symbol display area (such as by displaying a plurality of reels spinning and stopping in association with the symbol display areas), as indicated by block 104. In this example embodiment, for each symbol of the set of symbols, that symbol is included in one of a plurality of different groups of the symbols. Additionally, in this example embodiment, each group of the symbols includes at least two different symbols of the set of symbols.
The gaming system determines if a triggering event associated with one of the groups of the symbols occurs, as indicated by diamond 106. If the gaming system determines that no such triggering event has occurred, the process 100 proceeds to block 110, described below. If, on the other hand, the gaming system determines that a triggering event associated with one of the groups of the symbols has occurred, for each of at least one displayed symbol in that group of the symbols, the gaming system replaces that displayed symbol with a different one of the symbols in that group of the symbols, as indicated by block 108. The gaming system determines any awards associated with the displayed symbols, as indicated by the block 110, and displays any determined awards, as indicated by block 112.

It should thus be appreciated that, in this example embodiment, each group of the symbols includes a different low-value symbol, a different high-value symbol, and a different triggering symbol. More specifically, in this example embodiment: (1) Group 1 includes the low-value symbol L1, the high-value symbol H1, and the triggering symbol T1; (2) Group 2 includes the low-value symbol L2, the high-value symbol H2, and the triggering symbol T2; (3) Group 3 includes the low-value symbol L3, the high-value symbol H3, and the triggering symbol T3; (4) Group 4 includes the low-value symbol L4, the high-value symbol H4, and the triggering symbol T4; and (5) Group 5 includes the low-value symbol L5, the high-value symbol H5, and the triggering symbol T5.
It should also be appreciated that, in this example embodiment, each particular symbol is categorized in or included in only one of the five groups of the symbols and in only one of the three subsets of the symbols. Put differently, in this example embodiment, none of the groups of the symbols shares a same one of the symbols and none of the subsets of the symbols shares a same one of the symbols.
In this example embodiment, the gaming system displays, such as on a display device 1116 (described below), a plurality of symbol display areas 210a, 210b, 210c, 210d, 210e, 210f, 210g, 210h, 210i, 210j, 210k, 210l, 210m, 210n, and 2100o arranged in a 3×5 grid or matrix. The gaming system also displays a plurality of reels 205a, 205b, 205c, 205d, and 205e, each of which includes a plurality of the symbols of the set of symbols, in association with the symbol display areas. More specifically, each reel 205a, 205b, 205c, 205d, and 205e is associated with, and configured to display symbols at, a plurality of the symbol display areas. In this example embodiment: (a) the reel 205a is associated with, and configured to display symbols at, the symbol display areas 210a, 210f, and 210k; (b) the reel 205b is associated with, and configured to display symbols at, the symbol display areas 210b, 210g, and 210l; (c) the reel 205c is associated with, and configured to display symbols at, the symbol display areas 210c, 210h, and 210m; (d) the reel 205d is associated with, and configured to display symbols at, the symbol display areas 210d, 210i, and 210n; and (e) the reel 205e is associated with, and configured to display symbols at, the symbol display areas 210e, 210j, and 210o. The slot game is associated with a plurality of paylines (not shown for clarity), each of which is associated with a different plurality of the symbol display areas.
The gaming system also displays: (a) a message box 230 that displays a variety of messages or indications before, during, or after play of the slot game; (b) a plurality of buttons actuatable by the player, including: (i) a Bet Per Line button 231 that, when actuated by the player, causes the gaming system to enable the player to select an amount to bet on each wagered-on payline; (ii) a Select Lines button 232 that, when actuated by the player, causes the gaming system to enable the player to select the paylines on which the player desires to wager for a play of the slot game; (iii) a Menu button 233 that, when actuated by the player, causes the gaming system to display additional information about the slot game, such as the paytable for the slot game and/or the rules of the slot game; (iv) a Max Bet button 234 that, when actuated by the player, causes the gaming system to set the amount bet on each payline to a maximum amount and to set the quantity of paylines on which the player desires to wager to a maximum quantity of the paylines; and (v) a Spin button 235 that, when actuated by the player, causes the gaming system to initiate a play of the slot game; and (c) a plurality of meters including: (i) a bet meter 236 that displays any bet placed on a play of the slot game (in credit or currency form), (ii) a credit meter 237 that displays the player's credit balance (in credit or currency form), and (iii) an award meter 238 that displays any awards won for the play of the slot game (in credit or currency form).
As noted above, the slot game includes a symbol replacement feature that the gaming system provides upon an occurrence of a triggering event. In this example embodiment, each group of the symbols is associated with a different triggering event, and the symbol replacement feature varies based on which particular triggering event occurs.
Turning to the triggering events, generally, for each group of the symbols in this example embodiment, the triggering event associated with that group of the symbols occurs when the triggering symbol included in that group of the symbols is displayed at each symbol display area of one of the columns of the symbol display areas. More specifically: (a) the triggering event associated with Group 1 occurs when the T1 symbol is displayed at each symbol display area of one of the columns of the symbol display areas, (b) the triggering event associated with Group 2 occurs when the T2 symbol is displayed at each symbol display area of one of the columns of the symbol display areas, (c) the triggering event associated with Group 3 occurs when the T3 symbol is displayed at each symbol display area of one of the columns of the symbol display areas, (d) the triggering event associated with Group 4 occurs when the T4 symbol is displayed at each symbol display area of one of the columns of the symbol display areas, and (e) the triggering event associated with Group 5 occurs when the T5 symbol is displayed at each symbol display area of one of the columns of the symbol display areas.
Turning to the symbol replacement feature, generally, for each group of the symbols in this example embodiment, when the triggering event associated with that group of the symbols occurs, the gaming system replaces any displayed low-value symbols included in that group of the symbols and any triggering symbols included in that group of the symbols with the high-value symbol included in that group of the symbols. More specifically: (a) when the triggering event associated with Group 1 occurs, the gaming system replaces any displayed L1 symbols and any displayed T1 symbols with an H1 symbol, (b) when the triggering event associated with Group 2 occurs, the gaming system replaces any displayed L2 symbols and any displayed T2 symbols with an H2 symbol, (c) when the triggering event associated with Group 3 occurs, the gaming system replaces any displayed L3 symbols and any displayed T3 symbols with an H3 symbol, (d) when the triggering event associated with Group 4 occurs, the gaming system replaces any displayed L4 symbols and any displayed T4 symbols with an H4 symbol, and (e) when the triggering event associated with Group 5 occurs, the gaming system replaces any displayed L5 symbols and any displayed T5 symbols with an H5 symbol.
Turning to FIG. 2A, the gaming system receives a deposit of value from a player and credits the player with 1,000 credits (as shown in the credit meter 237). The gaming system displays the following message in the message box 230: “PLACE A BET AND PRESS ‘SPIN’ TO SPIN THE REELS! WATCH FOR A TRIGGERING EVENT THAT CAUSES CERTAIN HIGH-VALUE SYMBOLS TO REPLACE CERTAIN LOW-VALUE SYMBOLS!”
As shown in FIG. 2B, the gaming system receives a bet of 30 credits (as shown in the bet meter 236) and an actuation of the Spin button 235 from the player. Upon receiving the actuation of the Spin button 235, the gaming system reduces the player's credit balance by the 30 credit wager (as shown in the credit meter 237); initiates a play of the slot game; and displays the reels 205a, 205b, 205c, 205d, and 205e spinning. The gaming system displays the following message in the message box 230: “PLEASE WAIT WHILE THE REELS SPIN . . . .”
As illustrated in FIG. 2C, the gaming system stops spinning the reels 205a, 205b, 205c, 205d, and 205e such that: (a) T3 symbol 220a is displayed at the symbol display area 210a, (b) L3 symbol 220b is displayed at the symbol display area 210b, (c) H3 symbol 220c is displayed at the symbol display area 210c, (d) L3 symbol 220d is displayed at the symbol display area 210d, (e) L1 symbol 220e is displayed at the symbol display area 210e, (f) T3 symbol 220f is displayed at the symbol display area 210f, (g) H1 symbol 220g is displayed at the symbol display area 210g, (h) L1 symbol 220h is displayed at the symbol display area 210h, (i) L3 symbol 220i is displayed at the symbol display area 210i, (j) H3 symbol 220j is displayed at the symbol display area 210j, (k) T3 symbol 220k is displayed at the symbol display area 210k, (l) L2 symbol 220l is displayed at the symbol display area 210l, (m) H2 symbol 220m is displayed at the symbol display area 210m, (n) L3 symbol 220n is displayed at the symbol display area 210n, and (o) L4 symbol 220o is displayed at the symbol display area 210o. 
In this example embodiment, before making any award determinations based on the displayed symbols, the gaming system determines whether to provide the symbol replacement feature and, therefore, determines whether any of the triggering events occurred based on the displayed symbols. In this instance, the gaming system determines that the triggering event associated with Group 3 occurred because the T3 symbol (i.e., the triggering symbol associated with Group 3) is displayed at each symbol display area of the column of symbol display areas associated with the reel 205a (i.e., the symbol display areas 210a, 210f, and 210k). The gaming system displays the following message in the message box 230: “THE TRIGGERING EVENT OCCURRED! PLEASE WAIT WHILE ALL TRIGGERING SYMBOLS T3 AND ALL LOW-VALUE SYMBOLS L3 ARE REPLACED WITH THE HIGH-VALUE SYMBOL H3!”
Accordingly, as illustrated in FIG. 2D, the gaming system replaces each displayed T3 and L3 symbol (i.e., each low-value symbol and each triggering symbol included in Group 3) with the H3 symbol (i.e., the high-value symbol included in Group 3). More specifically, the gaming system replaces: (a) the T3 symbol 220a with the H3 symbol 221a, (b) the L3 symbol 220b with the H3 symbol 221b, (c) the L3 symbol 220d with the H3 symbol 221d, (d) the T3 symbol 220f with the H3 symbol 221f, (e) the L3 symbol 220i with the H3 symbol 221i, (f) the T3 symbol 220k with the H3 symbol 221k, and (g) the L3 symbol 220n with the H3 symbol 221n. 
Thereafter, the gaming system determines any awards associated with the symbols displayed at the symbol display areas by determining whether any winning combinations of the symbols included in the paytable (not shown) associated with the slot game are displayed at the symbol display areas associated with any of the wagered-on paylines (not shown). In this instance, the gaming system determines: (a) an award of 100 credits associated with the H3-H3-H3-H3 winning symbol combination displayed at the symbol display areas associated with a payline 215a; and (b) an award of 1,000 credits associated with the H3-H3-H3-H3-H3 winning symbol combination displayed at the symbol display areas associated with a payline 215b. The gaming system displays the total award of 1,100 credits in the award meter 238 and updates the player's credit meter 237 to reflect the total award of 1,100 credits. The gaming system displays the following message in the message box 230: “CONGRATULATIONS, YOU WIN 1,100 CREDITS!”
Second Example Embodiment
FIGS. 3A and 3B illustrate screen shots of another example embodiment of the gaming system of the present disclosure providing the slot game having the symbol replacement feature. In this example embodiment, as indicated in Table 2 below, the slot game employs the following set of a plurality of different symbols: L1, L2, L3, L4, L5, H1, H2, H3, H4, H5, T1, T2, T3, T4, and T5. As also indicated in Table 2 below, each symbol is categorized or included in: (a) one of the following three symbol value subsets: (i) a low-value symbol subset, (ii) a high-value symbol subset, and (iii) a triggering symbol subset; and (b) one of the following five symbol groups: (i) Group 1, (ii) Group 2, (iii) Group 3, (iv) Group 4, and (v) Group 5.

It should thus be appreciated that, in this example embodiment, each group of the symbols includes a different low-value symbol, a different high-value symbol, and a different triggering symbol. More specifically, in this example embodiment: (1) Group 1 includes the low-value symbol L1, the high-value symbol H1, and the triggering symbol T1; (2) Group 2 includes the low-value symbol L2, the high-value symbol H2, and the triggering symbol T2; (3) Group 3 includes the low-value symbol L3, the high-value symbol H3, and the triggering symbol T3; (4) Group 4 includes the low-value symbol L4, the high-value symbol H4, and the triggering symbol T4; and (5) Group 5 includes the low-value symbol L5, the high-value symbol H5, and the triggering symbol T5.
It should also be appreciated that, in this example embodiment, each particular symbol is categorized in or included in only one of the five groups of the symbols and in only one of the three subsets of the symbols. Put differently, in this example embodiment, none of the groups of the symbols shares a same one of the symbols and none of the subsets of the symbols shares a same one of the symbols.
In this example embodiment, the gaming system displays, such as on a display device 1116 (described below), a plurality of symbol display areas 310a, 310b, 310c, 310d, 310e, 310f, 310g, 310h, 310i, 310j, 310k, 3101, 310m, 310n, and 310o arranged in a 3×5 grid or matrix. The gaming system also displays a plurality of reels 305a, 305b, 305c, 305d, and 305e, each of which includes a plurality of the symbols of the set of symbols, in association with the symbol display areas. More specifically, each reel 305a, 305b, 305c, 305d, and 305e is associated with, and configured to display symbols at, a plurality of the symbol display areas. In this example embodiment: (a) the reel 305a is associated with, and configured to display symbols at, the symbol display areas 310a, 310f, and 310k; (b) the reel 305b is associated with, and configured to display symbols at, the symbol display areas 310b, 310g, and 310l; (c) the reel 305c is associated with, and configured to display symbols at, the symbol display areas 310c, 310h, and 310m; (d) the reel 305d is associated with, and configured to display symbols at, the symbol display areas 310d, 310i, and 310n; and (e) the reel 305e is associated with, and configured to display symbols at, the symbol display areas 310e, 310j, and 310o. The slot game is associated with a plurality of paylines (not shown for clarity), each of which is associated with a different plurality of the symbol display areas.
The gaming system also displays: (a) a message box 330 that displays a variety of messages or indications before, during, or after play of the slot game; (b) a plurality of buttons actuatable by the player, including: (i) a Bet Per Line button 331 that, when actuated by the player, causes the gaming system to enable the player to select an amount to bet on each wagered-on payline; (ii) a Select Lines button 332 that, when actuated by the player, causes the gaming system to enable the player to select the paylines on which the player desires to wager for a play of the slot game; (iii) a Menu button 333 that, when actuated by the player, causes the gaming system to display additional information about the slot game, such as the paytable for the slot game and/or the rules of the slot game; (iv) a Max Bet button 334 that, when actuated by the player, causes the gaming system to set the amount bet on each payline to a maximum amount and to set the quantity of paylines on which the player desires to wager to a maximum quantity of the paylines; and (v) a Spin button 335 that, when actuated by the player, causes the gaming system to initiate a play of the slot game; and (c) a plurality of meters including: (i) a bet meter 336 that displays any bet placed on a play of the slot game (in credit or currency form), (ii) a credit meter 337 that displays the player's credit balance (in credit or currency form), and (iii) an award meter 338 that displays any awards won for the play of the slot game (in credit or currency form).
As noted above, the slot game includes a symbol replacement feature that the gaming system provides upon an occurrence of a triggering event. In this example embodiment, each group of the symbols is associated with a different triggering event, and the symbol replacement feature varies based on which particular triggering event occurs.
Turning to the triggering events, generally, for each group of the symbols in this example embodiment, the triggering event associated with that group of the symbols occurs when the triggering symbol included in that group of the symbols is displayed at at least one of the symbol display areas. More specifically: (a) the triggering event associated with Group 1 occurs when the T1 symbol is displayed at at least one of the symbol display areas, (b) the triggering event associated with Group 2 occurs when T2 symbol is displayed at at least one of the symbol display areas, (c) the triggering event associated with Group 3 occurs when the T3 symbol is displayed at at least one of the symbol display areas, (d) the triggering event associated with Group 4 occurs when the T4 symbol is displayed at at least one of the symbol display areas, and (e) the triggering event associated with Group 5 occurs when the T5 symbol is displayed at at least one of the symbol display areas.
Turning to the symbol replacement feature, generally, for each group of the symbols in this example embodiment, when the triggering event associated with that group of the symbols occurs, the gaming system replaces: (a) any displayed low-value symbols included in that group of the symbols, (b) any displayed triggering symbols included in that group of the symbols, and (c) the symbols displayed at any symbol display areas in the same column as the symbol display areas (if any) displaying that low-value symbol or that triggering symbol with the high-value symbol included in that group of the symbols. More specifically: (a) when the triggering event associated with Group 1 occurs, the gaming system replaces: (i) any displayed L1 symbols, (ii) any displayed T1 symbols, and (iii) any symbols displayed at any symbol display areas in the same column as the symbol display areas (if any) displaying the L1 symbol or the T1 symbol with an H1 symbol; (b) when the triggering event associated with Group 2 occurs, the gaming system replaces: (i) any displayed L2 symbols, (ii) any displayed T2 symbols, and (iii) any symbols displayed at any symbol display areas in the same column as the symbol display areas (if any) displaying the L2 symbol or the T2 symbol with an H2 symbol; (c) when the triggering event associated with Group 3 occurs, the gaming system replaces: (i) any displayed L3 symbols, (ii) any displayed T3 symbols, and (iii) any symbols displayed at any symbol display areas in the same column as the symbol display areas (if any) displaying the L3 symbol or the T3 symbol with an H3 symbol; (d) when the triggering event associated with Group 4 occurs, the gaming system replaces: (i) any displayed L4 symbols, (ii) any displayed T4 symbols, and (iii) any symbols displayed at any symbol display areas in the same column as the symbol display areas (if any) displaying the L4 symbol or the T4 symbol with an H4 symbol; and (e) when the triggering event associated with Group 5 occurs, the gaming system replaces: (i) any displayed L5 symbols, (ii) any displayed T5 symbols, and (iii) any symbols displayed at any symbol display areas in the same column as the symbol display areas (if any) displaying the L5 symbol or the T5 symbol with an H5 symbol.
Turning to FIG. 3A, the gaming system has spun and stopped the reels 305a, 305b, 305c, 305d, and 305e such that: (a) H2 symbol 320a is displayed at the symbol display area 310a, (b) L4 symbol 320b is displayed at the symbol display area 310b, (c) H5 symbol 320c is displayed at the symbol display area 310c, (d) H4 symbol 320d is displayed at the symbol display area 310d, (e) L3 symbol 320e is displayed at the symbol display area 310e, (f) L1 symbol 320f is displayed at the symbol display area 310f, (g) H3 symbol 320g is displayed at the symbol display area 310g, (h) T2 symbol 320h is displayed at the symbol display area 310h, (i) H2 symbol 320i is displayed at the symbol display area 310i, (j) H5 symbol 320j is displayed at the symbol display area 310j, (k) L3 symbol 320k is displayed at the symbol display area 310k, (l) L2 symbol 320l is displayed at the symbol display area 310l, (m) L4 symbol 320m is displayed at the symbol display area 310m, (n) L1 symbol 320n is displayed at the symbol display area 310n, and (o) L2 symbol 3200 is displayed at the symbol display area 310o. 
In this example embodiment, before making any award determinations based on the displayed symbols, the gaming system determines whether to provide the symbol replacement feature and, therefore, determines whether any of the triggering events occurred based on the displayed symbols. In this instance, the gaming system determines that the triggering event associated with Group 2 occurred because the T2 symbol (i.e., the triggering symbol included in Group 2) is displayed at at least one of the symbol display areas (i.e., the symbol display area 310h). The gaming system displays the following message in the message box 330: “THE TRIGGERING EVENT OCCURRED! PLEASE WAIT WHILE ALL TRIGGERING SYMBOLS T2, ALL LOW-VALUE SYMBOLS L2, AND ALL SYMBOLS DISPLAYED IN THE SAME COLUMN AS THE T2 AND L2 SYMBOLS ARE REPLACED WITH THE HIGH-VALUE SYMBOL H2!”
Accordingly, as illustrated in FIG. 3B, the gaming system replaces: (a) any displayed L2 symbols, (b) any displayed T2 symbols, and (c) any symbols displayed at any symbol display areas in the same column as the symbol display areas (if any) displaying the L2 symbol or the T2 symbol with an H2 symbol. More specifically, the gaming system replaces: (a) the L2 symbol 320l with the H2 symbol 321l; (b) the H3 symbol 320g and the L4 symbol 320b, which are displayed at the symbol display areas in the same column as the symbol display area that formerly displayed the L2 symbol 320l, with the H2 symbol 321g and the H2 symbol 321b; (c) the T2 symbol 320h with the H2 symbol 321h; (d) the H5 symbol 320c and the L4 symbol 320m, which are displayed at the symbol display areas in the same column as the symbol display area that formerly displayed the T2 symbol 320h, with the H2 symbol 321c and the H2 symbol 321m; (e) the L2 symbol 3200 with the H2 symbol 321o; and (f) the L3 symbol 320e and the H5 symbol 320j, which are displayed at the symbol display areas in the same column as the symbol display area that formerly displayed the L2 symbol 320o, with the H2 symbol 321e and the H2 symbol 321i. 
Thereafter, the gaming system determines any awards associated with the symbols displayed at the symbol display areas by determining whether any winning combinations of the symbols included in the paytable (not shown) associated with the slot game are displayed at the symbol display areas associated with any of the wagered-on paylines (not shown). In this instance, the gaming system determines: (a) an award of 10 credits associated with the H2-H2-H2 winning symbol combination displayed at the symbol display areas associated with a payline 315a; (b) an award of 500 credits associated with the H2-H2-H2-H2-H2 winning symbol combination displayed at the symbol display areas associated with a payline 315b; and (c) an award of 500 credits associated with the H2-H2-H2-H2-H2 winning symbol combination displayed at the symbol display areas associated with a payline 315c. The gaming system displays the total award of 1,010 credits in the award meter 338 and updates the player's credit meter 337 to reflect the total award of 1,010 credits. The gaming system displays the following message in the message box 330: “CONGRATULATIONS, YOU WIN 1,010 CREDITS!”

It should thus be appreciated that, in this example embodiment, each group of the symbols includes a different low-value symbol and a different high-value symbol. More specifically, in this example embodiment: (1) Group 1 includes the low-value symbol L1 and the high-value symbol H1; (2) Group 2 includes the low-value symbol L2 and the high-value symbol H2; (3) Group 3 includes the low-value symbol L3 and the high-value symbol H3; (4) Group 4 includes the low-value symbol L4 and the high-value symbol H4; and (5) Group 5 includes the low-value symbol L5 and the high-value symbol H5.
It should also be appreciated that, in this example embodiment, each particular symbol is categorized in or included in only one of the five groups of the symbols and in only one of the two subsets of the symbols. Put differently, in this example embodiment, none of the groups of the symbols shares a same one of the symbols and none of the subsets of the symbols shares a same one of the symbols.
In this example embodiment, the gaming system displays, such as on a display device 1116 (described below), a plurality of symbol display areas 410a, 410b, 410c, 410d, 410e, 410f, 410g, 410h, 410i, 410j, 410k, 410l, 410m, 410n, and 410o arranged in a 3×5 grid or matrix. The gaming system also displays a plurality of reels 405a, 405b, 405c, 405d, and 405e, each of which includes a plurality of the symbols of the set of symbols, in association with the symbol display areas. More specifically, each reel 405a, 405b, 405c, 405d, and 405e is associated with, and configured to display symbols at, a plurality of the symbol display areas. In this example embodiment: (a) the reel 405a is associated with, and configured to display symbols at, the symbol display areas 410a, 410f, and 410k; (b) the reel 405b is associated with, and configured to display symbols at, the symbol display areas 410b, 410g, and 410l; (c) the reel 405c is associated with, and configured to display symbols at, the symbol display areas 410c, 410h, and 410m; (d) the reel 405d is associated with, and configured to display symbols at, the symbol display areas 410d, 410i, and 410n; and (e) the reel 405e is associated with, and configured to display symbols at, the symbol display areas 410e, 410j, and 410o. The slot game is associated with a plurality of paylines (not shown for clarity), each of which is associated with a different plurality of the symbol display areas.
The gaming system also displays: (a) a message box 430 that displays a variety of messages or indications before, during, or after play of the slot game; (b) a plurality of buttons actuatable by the player, including: (i) a Bet Per Line button 431 that, when actuated by the player, causes the gaming system to enable the player to select an amount to bet on each wagered-on payline; (ii) a Select Lines button 432 that, when actuated by the player, causes the gaming system to enable the player to select the paylines on which the player desires to wager for a play of the slot game; (iii) a Menu button 433 that, when actuated by the player, causes the gaming system to display additional information about the slot game, such as the paytable for the slot game and/or the rules of the slot game; (iv) a Max Bet button 434 that, when actuated by the player, causes the gaming system to set the amount bet on each payline to a maximum amount and to set the quantity of paylines on which the player desires to wager to a maximum quantity of the paylines; and (v) a Spin button 435 that, when actuated by the player, causes the gaming system to initiate a play of the slot game; and (c) a plurality of meters including: (i) a bet meter 436 that displays any bet placed on a play of the slot game (in credit or currency form), (ii) a credit meter 437 that displays the player's credit balance (in credit or currency form), and (iii) an award meter 438 that displays any awards won for the play of the slot game (in credit or currency form).
As noted above, the slot game includes a symbol replacement feature that the gaming system provides upon an occurrence of a triggering event. In this example embodiment, each group of the symbols is associated with a different triggering event, and the symbol replacement feature varies based on which particular triggering event occurs.
Turning to the triggering events, generally, for each group of the symbols in this example embodiment, the triggering event associated with that group of the symbols occurs when each symbol included in that group of the symbols is displayed at at least one of the symbol display areas. More specifically: (a) the triggering event associated with Group 1 occurs when the L1 symbol is displayed at at least one of the symbol display areas and the H1 symbol is displayed at at least one of the symbol display areas, (b) the triggering event associated with Group 2 occurs when the L2 symbol is displayed at at least one of the symbol display areas and the H2 symbol is displayed at at least one of the symbol display areas, (c) the triggering event associated with Group 3 occurs when the L3 symbol is displayed at at least one of the symbol display areas and the H3 symbol is displayed at at least one of the symbol display areas, (d) the triggering event associated with Group 4 occurs when the L4 symbol is displayed at at least one of the symbol display areas and the H4 symbol is displayed at at least one of the symbol display areas, and (e) the triggering event associated with Group 5 occurs when the L5 symbol is displayed at at least one of the symbol display areas and the H5 symbol is displayed at at least one of the symbol display areas.
Turning to the symbol replacement feature, generally, for each group of the symbols in this example embodiment, when the triggering event associated with that group of the symbols occurs, the gaming system replaces: (a) any displayed low-value symbols included in that group of the symbols and any symbols displayed at symbol display areas to the right of and in the same row as the symbol display areas displaying those low-value symbols with the high-value symbol in that group of the symbols, and (b) any symbols displayed at symbol display areas to the right of and in the same row as any symbol display areas displaying the high-value symbol in that group of the symbols with the high-value symbol in that group of the symbols. More specifically: (a) when the triggering event associated with Group 1 occurs, the gaming system replaces: (i) any displayed L1 symbols, (ii) the symbols displayed at any symbol display areas to the right of and in the same row as the symbol display areas displaying such L1 symbols, and (iii) the symbols displayed at any symbol display areas to the right of and in the same row as any symbol display areas displaying the H1 symbol with the H1 symbol; (b) when the triggering event associated with Group 2 occurs, the gaming system replaces: (i) any displayed L2 symbols, (ii) the symbols displayed at any symbol display areas to the right of and in the same row as the symbol display areas displaying such L2 symbols, and (iii) the symbols displayed at any symbol display areas to the right of and in the same row as any symbol display areas displaying the H2 symbol with the H2 symbol; (c) when the triggering event associated with Group 3 occurs, the gaming system replaces: (i) any displayed L3 symbols, (ii) the symbols displayed at any symbol display areas to the right of and in the same row as the symbol display areas displaying such L3 symbols, and (iii) the symbols displayed at any symbol display areas to the right of and in the same row as any symbol display areas displaying the H3 symbol with the H3 symbol; (d) when the triggering event associated with Group 4 occurs, the gaming system replaces: (i) any displayed L4 symbols, (ii) the symbols displayed at any symbol display areas to the right of and in the same row as the symbol display areas displaying such L4 symbols, and (iii) the symbols displayed at any symbol display areas to the right of and in the same row as any symbol display areas displaying the H4 symbol with the H4 symbol; and (e) when the triggering event associated with Group 5 occurs, the gaming system replaces: (i) any displayed L5 symbols, (ii) the symbols displayed at any symbol display areas to the right of and in the same row as the symbol display areas displaying such L5 symbols, and (iii) the symbols displayed at any symbol display areas to the right of and in the same row as any symbol display areas displaying the H5 symbol with the H5 symbol.
Turning to FIG. 4A, the gaming system has spun and stopped the reels 405a, 405b, 405c, 405d, and 405e of the first set such that: (a) L4 symbol 420a is displayed at the symbol display area 410a, (b) H2 symbol 420b is displayed at the symbol display area 410b, (c) L1 symbol 420c is displayed at the symbol display area 410c, (d) L3 symbol 420d is displayed at the symbol display area 410d, (e) L3 symbol 420e is displayed at the symbol display area 410e, (f) H5 symbol 420f is displayed at the symbol display area 410f, (g) L1 symbol 420g is displayed at the symbol display area 410g, (h) H5 symbol 420h is displayed at the symbol display area 410h, (i) H4 symbol 420i is displayed at the symbol display area 410i, (j) H5 symbol 420j is displayed at the symbol display area 410j, (k) H2 symbol 420k is displayed at the symbol display area 410k, (l) L3 symbol 420l is displayed at the symbol display area 410l, (m) L4 symbol 420m is displayed at the symbol display area 410m, (n) L1 symbol 420n is displayed at the symbol display area 410n, and (o) H2 symbol 4200 is displayed at the symbol display area 410o. 
In this example embodiment, before making any award determinations based on the displayed symbols, the gaming system determines whether to provide the symbol replacement feature and, therefore, determines whether any of the triggering events occurred based on the displayed symbols. In this instance, the gaming system determines that the triggering event associated with Group 4 occurred because the L4 symbol is displayed at at least one of the symbol display areas and the H4 symbol is displayed at at least one of the symbol display areas. The gaming system displays the following message in the message box 430: “THE TRIGGERING EVENT OCCURRED! PLEASE WAIT WHILE ALL LOW-VALUE SYMBOLS L4 AND ALL SYMBOLS DISPLAYED TO THE RIGHT OF AND IN THE SAME ROW AS THE LOW-VALUE SYMBOLS L4 AND THE HIGH-VALUE SYMBOLS H4 ARE REPLACED WITH THE HIGH-VALUE SYMBOL H4!”
Accordingly, as illustrated in FIG. 4B, the gaming system replaces: (i) any displayed L4 symbols, (ii) the symbols displayed at any symbol display areas to the right of and in the same row as the symbol display areas displaying such L4 symbols, and (iii) the symbols displayed at any symbol display areas to the right of and in the same row as any symbol display areas displaying the H4 symbol with the H4 symbol. More specifically, the gaming system replaces: (a) the L4 symbol 420a with the H4 symbol 421a; (b) the H2 symbol 420b, the L1 symbol 420c, the L3 symbol 420d, and the L3 symbol 420e, which are displayed at the symbol display areas to the right of and in the same row as the symbol display area 410a that formerly displayed the L4 symbol 420a, with the H4 symbol 421b, and H4 symbol 421c, the H4 symbol 421d, and the H4 symbol 421e; (c) the H5 symbol 420j, which is displayed at the symbol display area to the right of and in the same row as the symbol display area 410i that displays the H4 symbol 420i, with the H4 symbol 421j; (d) the L4 symbol 420m with the H4 symbol 421m; and (e) the L1 symbol 420n and the H2 symbol 420o, which are displayed at the symbol display areas to the right of and in the same row as the symbol display area 410m that formerly displayed the L4 symbol 420m, with the H4 symbol 421n and the H4 symbol 421o. 
Thereafter, the gaming system determines any awards associated with the symbols displayed at the symbol display areas by determining whether any winning combinations of the symbols included in the paytable (not shown) associated with the slot game are displayed at the symbol display areas associated with any of the wagered-on paylines (not shown). In this instance, the gaming system determines: (a) an award of 750 credits associated with the H4-H4-H4-H4-H4 winning symbol combination displayed at the symbol display areas associated with a payline 415a; (b) an award of 750 credits associated with the H4-H4-H4-H4-H4 winning symbol combination displayed at the symbol display areas associated with a payline 415b; and (c) an award of 750 credits associated with the H4-H4-H4-H4-H4 winning symbol combination displayed at the symbol display areas associated with a payline 415c. The gaming system displays the total award of 2,250 credits in the award meter 438 and updates the players credit meter 437 to reflect the total award of 2,250 credits. The gaming system displays the following message in the message box 430: “CONGRATULATIONS, YOU WIN 2,250 CREDITS!”
Variations
It should be appreciated that the triggering event that causes the gaming system to provide the reel replacement feature may be any suitable event, such as (but not limited to): (a) the display of a designated symbol (such as a triggering symbol) in each of a designated quantity of at least one of the symbol display areas following a spin of the reels; (b) the display of a designated symbol (such as a triggering symbol) in each of one or more designated symbol display areas; (c) the display of a designated symbol combination (such as a combination of a plurality of triggering symbols); (d) the display of a winning symbol combination following a spin of the reels; (e) the gaming system providing the player a designated award (such as a progressive award or a jackpot award); (f) a total quantity of plays of the slot game played by the player during a gaming session reaching a designated quantity of plays; (g) the gaming system receiving a deposit of value to fund the gaming system at least a designated quantity of times during a gaming session; (h) a total amount wagered by the player during a gaming session reaching a designated amount wagered; (i) a total amount of credits or currency won by the player during a gaming session reaching a designated amount won; (j) a total amount of credits or currency lost by the player during a gaming session reaching a designated amount lost; (k) a time of day reaching a designated time of day; (l) a length of a gaming session reaching a designated length of time; (m) a play of a bonus game having not been provided within a designated amount of time during a gaming session; (n) a play of a bonus game having not been provided within a designated quantity of plays of the slot game during a gaming session; (o) the player achieving a designated quantity of consecutive winning outcomes during a gaming session; (p) the player achieving a designated quantity of consecutive losing outcomes during a gaming session; (q) a total quantity of winning outcomes achieved by the player during a gaming session reaching a designated quantity; (r) a total quantity of losing outcomes achieved by the player during a gaming session reaching a designated quantity; (s) a total amount of coin-in during a gaming session reaching a designated quantity; (t) a credit balance of the player reaching a designated credit balance; (u) a total amount of currency deposited by the player during a gaming session reaching a designated amount; (v) a change in frequency of play reaching a designated amount; (w) a ticket, coupon, or promotion being inserted or otherwise entered (such as by typing in a promotion code or scanning a barcode); (x) a designated quantity of credits being transferred onto the gaming system; and/or (y) player tracking points being converted into one or more credits.
In various embodiments, the slot game is associated with a single triggering event rather than a separate triggering event associated with each group of the symbols. It should be appreciated that, in certain such embodiments, upon an occurrence of the triggering event, the gaming system provides the symbol replacement feature in association with a randomly determined (or other suitably determined) group of the symbols or sequentially for each group of the symbols.
In certain embodiments, the slot game is associated with a plurality of triggering events that are not associated with any particular group(s) of the symbols. It should be appreciated that, in certain such embodiments, upon an occurrence of the triggering event, the gaming system provides the symbol replacement feature in association with a randomly determined (or other suitably determined) group of the symbols.
In certain embodiments, each group of the symbols is associated with a plurality of different triggering events, and each such triggering event is associated with a different variation of the symbol replacement feature. Thus, in these embodiments, for a particular group of the symbols, the type of symbol replacement feature that the gaming system provides depends on which of the triggering events associated with that group of the symbols occurs. For instance, in one example embodiment, Group 1 is associated with: (a) a first triggering event that occurs when the triggering symbol included in Group 1 is displayed at at least one of the symbol display areas, and (b) a second triggering event that occurs when the triggering symbol included in Group 1 is displayed at each symbol display area of a column of symbol display areas. In this example embodiment: (a) when the first triggering event occurs, the gaming system replaces all displayed low-value symbols included in Group 1 and all displayed triggering symbols included in group 1 with the high-value symbol included in Group 1; and (b) when the second triggering event occurs, the gaming system replaces all displayed low-value symbols included in Group 1, all displayed triggering symbols included in Group 1, and all other symbols displayed at symbol display areas in the same columns as such displayed low-value symbols and triggering symbols with the high-value symbol included in Group 1. Thus, in this example embodiment, the gaming system provides progressively more valuable symbol replacement features as the triggering events become less likely to occur.
In various embodiments, upon an occurrence of a triggering event associated with a particular group of the symbols, the gaming system provides an ancillary symbol replacement feature in addition to replacing any displayed instances of (at least) a first one of the symbols in that group of the symbols with a second different one of the symbols in that particular group of the symbols. For instance, in various embodiments, the gaming system provides ancillary symbol replacement feature by: (a) replacing any symbols displayed at any symbol display areas above and in the same column as the symbol display area(s) displaying such first symbols with the second symbol, (b) replacing any symbols displayed at any symbol display areas below and in the same column as the symbol display area(s) displaying such first symbols with the second symbol, (c) replacing any symbols displayed at any symbol display areas in the same column as the symbol display area(s) displaying such first symbols with the second symbol, (d) replacing any symbols displayed at any symbol display areas to the right of and in the same row as the symbol display area(s) displaying such first symbols with the second symbol, (e) replacing any symbols displayed at any symbol display areas to the left of and in the same row as the symbol display area(s) displaying such first symbols with the second symbol, (f) replacing any symbols displayed at any symbol display areas in the same row as the symbol display area(s) displaying such first symbols with the second symbol, (g) replacing any symbols displayed at one or more randomly selected symbol display areas with the second symbol, (h) replacing any symbols displayed at one or more player-selected symbol display areas with the second symbol; (i) replacing any symbols displayed at any symbol display areas along a line extending diagonally upward and to the right of the symbol display area(s) displaying such first symbols with the second symbol; (j) replacing any symbols displayed at any symbol display areas along a line extending diagonally upward and to the left of the symbol display area(s) displaying such first symbols with the second symbol; (k) replacing any symbols displayed at any symbol display areas along a line extending diagonally downward and to the right of the symbol display area(s) displaying such first symbols with the second symbol; (l) replacing any symbols displayed at any symbol display areas along a line extending diagonally downward and to the left of the symbol display area(s) displaying such first symbols with the second symbol; (m) replacing any symbols displayed at any symbol display areas along a line extending diagonally upward and to the right of and diagonally downward and to the left of the symbol display area(s) displaying such first symbols with the second symbol; (n) replacing any symbols displayed at any symbol display areas along a line extending diagonally upward and to the left of and diagonally downward and to the right of the symbol display area(s) displaying such first symbols with the second symbol; or (o) any suitable combination thereof).
In certain embodiments including a plurality of different triggering events, one or more of the triggering events are associated with different ancillary symbol replacement feature. In one such embodiments, the rarer the triggering event, the more valuable the ancillary symbol replacement feature.
In various embodiments, the gaming system provides one or more of the ancillary symbol replacement features when the slot game is a bonus game and does not provide any such ancillary symbol replacement features when the slot game is a primary game. In other words, in these embodiments, the gaming system provides the symbol replacement feature without any ancillary symbol replacement features when the triggering event occurs during primary game play, and provides the symbol replacement feature along with one or more ancillary symbol replacement features when the triggering event occurs during bonus game play.
In certain embodiments, if the triggering event occurs, the gaming system makes a first award determination before providing the symbol replacement feature and a second award determination after providing the symbol replacement feature.
In various embodiments, at least two groups of the symbols share a same one of the symbols. For instance, in one such embodiment, at least two groups of the symbols share a Wild symbol. In other embodiments, at least two sub-sets of the symbols share a same one of the symbols. For instance, in one such embodiment, at least two sub-sets of the symbols share a Wild symbol.
It should be appreciated that the set of symbols may be categorized or included in groups in any suitable manner. For instance, in one embodiment, the gaming system includes symbols sharing a common color in the same group (e.g., Group 1 includes red symbols, Group 2 includes blue symbols, etc.). In another embodiment, the gaming system includes symbols sharing a common theme in the same group (e.g., Group 1 includes royal symbols, Group 2 includes animal symbols, and the like). In another embodiment, the gaming system includes symbols of a same size in the same group (e.g., Group 1 includes symbols of a first size, Group 2 includes symbols of a second size that is smaller than the first size, etc.). In another embodiment, the gaming system includes symbols having the same shape in the same group (e.g., Group 1 includes star-shaped symbols, Group 2 includes circular symbols, Group 3 includes triangular symbols, etc.). In another embodiment, the gaming system includes single symbols in Group 1 and double symbols in Group 2.

Operation of Primary or Base Games and/or Secondary or Bonus Games
In various embodiments, an EGM may be implemented in one of a variety of different configurations. In various embodiments, the EGM may be implemented as one of: (a) a dedicated EGM wherein computerized game programs executable by the EGM for controlling any primary or base games (referred to herein as “primary games”) and/or any secondary or bonus games or other functions (referred to herein as “secondary games”) displayed by the EGM are provided with the EGM prior to delivery to a gaming establishment or prior to being provided to a player; and (b) a changeable EGM wherein computerized game programs executable by the EGM for controlling any primary games and/or secondary games displayed by the EGM are downloadable to the EGM through a data network or remote communication link after the EGM is physically located in a gaming establishment or after the EGM is provided to a player.
As generally explained above, in various embodiments in which the gaming system includes a central server, central controller, or remote host and a changeable EGM, the at least one memory device of the central server, central controller, or remote host stores different game programs and instructions executable by the at least one processor of the changeable EGM to control one or more primary games and/or secondary games displayed by the changeable EGM. More specifically, each such executable game program represents a different game or a different type of game that the at least one changeable EGM is configured to operate. In one example, certain of the game programs are executable by the changeable EGM to operate games having the same or substantially the same game play but different paytables. In different embodiments, each executable game program is associated with a primary game, a secondary game, or both. In certain embodiments, an executable game program is executable by the at least one processor of the at least one changeable EGM as a secondary game to be played simultaneously with a play of a primary game (which may be downloaded to or otherwise stored on the at least one changeable EGM), or vice versa.
In operation of such embodiments, the central server, central controller, or remote host is configured to communicate one or more of the stored executable game programs to the at least one processor of the changeable EGM. In different embodiments, a stored executable game program is communicated or delivered to the at least one processor of the changeable EGM by: (a) embedding the executable game program in a device or a component (such as a microchip to be inserted into the changeable EGM); (b) writing the executable game program onto a disc or other media; or (c) uploading or streaming the executable game program over a data network (such as a dedicated data network). After the executable game program is communicated from the central server, central controller, or remote host to the changeable EGM, the at least one processor of the changeable EGM executes the executable game program to enable the primary game and/or the secondary game associated with that executable game program to be played using the display device(s) and/or the input device(s) of the changeable EGM. That is, when an executable game program is communicated to the at least one processor of the changeable EGM, the at least one processor of the changeable EGM changes the game or the type of game that may be played using the changeable EGM.
In certain embodiments, the gaming system randomly determines any game outcome(s) (such as a win outcome) and/or award(s) (such as a quantity of credits to award for the win outcome) for a play of a primary game and/or a play of a secondary game based on probability data. In certain such embodiments, this random determination is provided through utilization of an RNG, such as a true RNG or a pseudo RNG, or any other suitable randomization process. In one such embodiment, each game outcome or award is associated with a probability, and the gaming system generates the game outcome(s) and/or the award(s) to be provided based on the associated probabilities. In these embodiments, since the gaming system generates game outcomes and/or awards randomly or based on one or more probability calculations, there is no certainty that the gaming system will ever provide any specific game outcome and/or award.
In certain embodiments, the gaming system maintains one or more predetermined pools or sets of predetermined game outcomes and/or awards. In certain such embodiments, upon generation or receipt of a game outcome and/or award request, the gaming system independently selects one of the predetermined game outcomes and/or awards from the one or more pools or sets. The gaming system flags or marks the selected game outcome and/or award as used. Once a game outcome or an award is flagged as used, it is prevented from further selection from its respective pool or set; that is, the gaming system does not select that game outcome or award upon another game outcome and/or award request. The gaming system provides the selected game outcome and/or award. At least U.S. Pat. Nos. 7,470,183; 7,563,163; and 7,833,092 and U.S. Patent Application Publication Nos. 2005/0148382, 2006/0094509, and 2009/0181743 describe various examples of this type of award determination.
In certain embodiments, the gaming system determines a predetermined game outcome and/or award based on the results of a bingo, keno, or lottery game. In certain such embodiments, the gaming system utilizes one or more bingo, keno, or lottery games to determine the predetermined game outcome and/or award provided for a primary game and/or a secondary game. The gaming system is provided or associated with a bingo card. Each bingo card consists of a matrix or array of elements, wherein each element is designated with separate indicia. After a bingo card is provided, the gaming system randomly selects or draws a plurality of the elements. As each element is selected, a determination is made as to whether the selected element is present on the bingo card. If the selected element is present on the bingo card, that selected element on the provided bingo card is marked or flagged. This process of selecting elements and marking any selected elements on the provided bingo cards continues until one or more predetermined patterns are marked on one or more of the provided bingo cards. After one or more predetermined patterns are marked on one or more of the provided bingo cards, game outcome and/or award is determined based, at least in part, on the selected elements on the provided bingo cards. At least U.S. Pat. Nos. 7,753,774; 7,731,581; 7,955,170; and 8,070,579 and U.S. Patent Application Publication No. 2011/0028201 describe various examples of this type of award determination.
In certain embodiments in which the gaming system includes a central server, central controller, or remote host and an EGM, the EGM is configured to communicate with the central server, central controller, or remote host for monitoring purposes only. In such embodiments, the EGM determines the game outcome(s) and/or award(s) to be provided in any of the manners described above, and the central server, central controller, or remote host monitors the activities and events occurring on the EGM. In one such embodiment, the gaming system includes a real-time or online accounting and gaming information system configured to communicate with the central server, central controller, or remote host. In this embodiment, the accounting and gaming information system includes: (a) a player database for storing player profiles, (b) a player tracking module for tracking players (as described below), and (c) a credit system for providing automated transactions. At least U.S. Pat. No. 6,913,534 and U.S. Patent Application Publication No. 2006/0281541 describe various examples of such accounting systems.
As noted above, in various embodiments, the gaming system includes one or more executable game programs executable by at least one processor of the gaming system to provide one or more primary games and one or more secondary games. The primary game(s) and the secondary game(s) may comprise any suitable games and/or wagering games, such as, but not limited to: electro-mechanical or video slot or spinning reel type games; video card games such as video draw poker, multi-hand video draw poker, other video poker games, video blackjack games, and video baccarat games; video keno games; video bingo games; and video selection games.
In certain embodiments in which the primary game is a slot or spinning reel type game, the gaming system includes one or more reels in either an electromechanical form with mechanical rotating reels or in a video form with simulated reels and movement thereof. Each reel displays a plurality of indicia or symbols, such as bells, hearts, fruits, numbers, letters, bars, or other images that typically correspond to a theme associated with the gaming system. In certain such embodiments, the gaming system includes one or more paylines associated with the reels. The example EGM 1110b shown in FIG. 6B includes a payline 1152 and a plurality of reels 1154. In certain embodiments, one or more of the reels are independent reels or unisymbol reels. In such embodiments, each independent reel generates and displays one symbol.
In various embodiments, one or more of the paylines is horizontal, vertical, circular, diagonal, angled, or any suitable combination thereof. In other embodiments, each of one or more of the paylines is associated with a plurality of adjacent symbol display areas on a requisite number of adjacent reels. In one such embodiment, one or more paylines are formed between at least two symbol display areas that are adjacent to each other by either sharing a common side or sharing a common corner (i.e., such paylines are connected paylines). The gaming system enables a wager to be placed on one or more of such paylines to activate such paylines. In other embodiments in which one or more paylines are formed between at least two adjacent symbol display areas, the gaming system enables a wager to be placed on a plurality of symbol display areas, which activates those symbol display areas.
In various embodiments, the gaming system provides one or more awards after a spin of the reels when specified types and/or configurations of the indicia or symbols on the reels occur on an active payline or otherwise occur in a winning pattern, occur on the requisite number of adjacent reels, and/or occur in a scatter pay arrangement.
In certain embodiments, the gaming system employs a ways to win award determination. In these embodiments, any outcome to be provided is determined based on a number of associated symbols that are generated in active symbol display areas on the requisite number of adjacent reels (i.e., not on paylines passing through any displayed winning symbol combinations). If a winning symbol combination is generated on the reels, one award for that occurrence of the generated winning symbol combination is provided. At least U.S. Pat. No. 8,012,011 and U.S. Patent Application Publication Nos. 2008/0108408 and 2008/0132320 describe various examples of ways to win award determinations.
In various embodiments, the gaming system includes a progressive award. Typically, a progressive award includes an initial amount and an additional amount funded through a portion of each wager placed to initiate a play of a primary game. When one or more triggering events occurs, the gaming system provides at least a portion of the progressive award. After the gaming system provides the progressive award, an amount of the progressive award is reset to the initial amount and a portion of each subsequent wager is allocated to the next progressive award. At least U.S. Pat. Nos. 5,766,079; 7,585,223; 7,651,392; 7,666,093; 7,780,523; and 7,905,778 and U.S. Patent Application Publication Nos. 2008/0020846, 2009/0123364, 2009/0123363, and 2010/0227677 describe various examples of different progressive gaming systems.
As generally noted above, in addition to providing winning credits or other awards for one or more plays of the primary game(s), in various embodiments the gaming system provides credits or other awards for one or more plays of one or more secondary games. The secondary game typically enables an award to be obtained addition to any award obtained through play of the primary game(s). The secondary game(s) typically produces a higher level of player excitement than the primary game(s) because the secondary game(s) provides a greater expectation of winning than the primary game(s) and is accompanied with more attractive or unusual features than the primary game(s). It should be appreciated that the secondary game(s) may be any type of suitable game, either similar to or completely different from the primary game.
In various embodiments, the gaming system automatically provides or initiates the secondary game upon the occurrence of a triggering event or the satisfaction of a qualifying condition. In other embodiments, the gaming system initiates the secondary game upon the occurrence of the triggering event or the satisfaction of the qualifying condition and upon receipt of an initiation input. In certain embodiments, the triggering event or qualifying condition is a selected outcome in the primary game(s) or a particular arrangement of one or more indicia on a display device for a play of the primary game(s), such as a “BONUS” symbol appearing on three adjacent reels along a payline following a spin of the reels for a play of the primary game. In other embodiments, the triggering event or qualifying condition occurs based on a certain amount of game play (such as number of games, number of credits, amount of time) being exceeded, or based on a specified number of points being earned during game play. It should be appreciated that any suitable triggering event or qualifying condition or any suitable combination of a plurality of different triggering events or qualifying conditions may be employed.
In other embodiments, at least one processor of the gaming system randomly determines when to provide one or more plays of one or more secondary games. In one such embodiment, no apparent reason is provided for the providing of the secondary game. In this embodiment, qualifying for a secondary game is not triggered by the occurrence of an event in any primary game or based specifically on any of the plays of any primary game. That is, qualification is provided without any explanation or, alternatively, with a simple explanation. In another such embodiment, the gaming system determines qualification for a secondary game at least partially based on a game triggered or symbol triggered event, such as at least partially based on play of a primary game.
In various embodiments, after qualification for a secondary game has been determined, the secondary game participation may be enhanced through continued play on the primary game. Thus, in certain embodiments, for each secondary game qualifying event, such as a secondary game symbol, that is obtained, a given number of secondary game wagering points or credits is accumulated in a “secondary game meter” configured to accrue the secondary game wagering credits or entries toward eventual participation in the secondary game. In one such embodiment, the occurrence of multiple such secondary game qualifying events in the primary game results in an arithmetic or exponential increase in the number of secondary game wagering credits awarded. In another such embodiment, any extra secondary game wagering credits may be redeemed during the secondary game to extend play of the secondary game.
In certain embodiments, no separate entry fee or buy-in for the secondary game is required. That is, entry into the secondary game cannot be purchased; rather, in these embodiments entry must be won or earned through play of the primary game, thereby encouraging play of the primary game. In other embodiments, qualification for the secondary game is accomplished through a simple “buy-in.” For example, qualification through other specified activities is unsuccessful, payment of a fee or placement of an additional wager “buys-in” to the secondary game. In certain embodiments, a separate side wager must be placed on the secondary game or a wager of a designated amount must be placed on the primary game to enable qualification for the secondary game. In these embodiments, the secondary game triggering event must occur and the side wager (or designated primary game wager amount) must have been placed for the secondary game to trigger.
In various embodiments in which the gaming system includes a plurality of EGMs, the EGMs are configured to communicate with one another to provide a group gaming environment. In certain such embodiments, the EGMs enable players of those EGMs to work in conjunction with one another, such as by enabling the players to play together as a team or group, to win one or more awards. In other such embodiments, the EGMs enable players of those EGMs to compete against one another for one or more awards. In one such embodiment, the EGMs enable the players of those EGMs to participate in one or more gaming tournaments for one or more awards. At least U.S. Patent Application Publication Nos. 2007/0123341, 2008/0070680, 2008/0176650, and 2009/0124363 describe various examples of different group gaming systems.
In various embodiments, the gaming system includes one or more player tracking systems. Such player tracking systems enable operators of the gaming system (such as casinos or other gaming establishments) to recognize the value of customer loyalty by identifying frequent customers and rewarding them for their patronage. Such a player tracking system is configured to track a player's gaming activity. In one such embodiment, the player tracking system does so through the use of player tracking cards. In this embodiment, a player is issued a player identification card that has an encoded player identification number that uniquely identifies the player. When the player's playing tracking card is inserted into a card reader of the gaming system to begin a gaming session, the card reader reads the player identification number off the player tracking card to identify the player. The gaming system timely tracks any suitable information or data relating to the identified player's gaming session. The gaming system also timely tracks when the player tracking card is removed to conclude play for that gaming session. In another embodiment, rather than requiring insertion of a player tracking card into the card reader, the gaming system utilizes one or more portable devices, such as a cell phone, a radio frequency identification tag, or any other suitable wireless device, to track when a gaming session begins and ends. In another embodiment, the gaming system utilizes any suitable biometric technology or ticket technology to track when a gaming session begins and ends.
In such embodiments, during one or more gaming sessions, the gaming system tracks any suitable information or data, such as any amounts wagered, average wager amounts, and/or the time at which these wagers are placed. In different embodiments, for one or more players, the player tracking system includes the player's account number, the player's card number, the player's first name, the player's surname, the player's preferred name, the player's player tracking ranking, any promotion status associated with the player's player tracking card, the player's address, the player's birthday, the player's anniversary, the player's recent gaming sessions, or any other suitable data. In various embodiments, such tracked information and/or any suitable feature associated with the player tracking system is displayed on a player tracking display. In various embodiments, such tracked information and/or any suitable feature associated with the player tracking system is displayed via one or more service windows that are displayed on the central display device and/or the upper display device. At least U.S. Pat. Nos. 6,722,985; 6,908,387; 7,311,605; 7,611,411; 7,617,151; and 8,057,298 describe various examples of player tracking systems.
It should be understood that various changes and modifications to the present embodiments described herein will be apparent to those skilled in the art. Such changes and modifications can be made without departing from the spirit and scope of the present subject matter and without diminishing its intended advantages. It is therefore intended that such changes and modifications be covered by the appended claims.
