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 partial reel re-spin feature. Generally, for a play of the slot game in various embodiments, the gaming system displays a randomly determined plurality of symbols of a first set of symbols at a plurality of symbol display areas (such as by displaying a first set of reels spinning and stopping in association with the symbol display areas). The gaming system makes an award determination based on the displayed symbols. Upon an occurrence of a triggering event (such as the display of a triggering symbol), the gaming system selects a designated set of a plurality of the symbol display areas (such as based on a proximity of those symbol display areas to the triggering symbol), and replaces the symbols of the first set of symbols displayed at the symbol display areas of the designated set with symbols from a second set of one or more symbols (such as by displaying a second set of reels spinning and stopping in association with the symbol display areas of the designated set). The gaming system makes another award determination based on the displayed symbols.
More specifically, in operation of one embodiment, for a play of the slot game, the gaming system displays a plurality of symbol display areas and, for each symbol display area, displays a randomly determined symbol of a first set of a plurality of symbols at that symbol display area by displaying a first set of reels spinning and stopping in association with the symbol display areas. In this embodiment, the first set of symbols includes a triggering symbol. The gaming system determines any awards based on the displayed symbols and displays any determined awards. The gaming system determines if the triggering symbol is displayed at one of the symbol display areas. If the gaming system determines that the triggering symbol is not displayed at any of the symbol display areas, the gaming system ends the play of the slot game. If, on the other hand, the gaming system determines that the triggering symbol is displayed at one of the symbol display areas, the gaming system provides the partial reel re-spin feature, described below.
More specifically, if the gaming system determines that the triggering symbol is displayed at one of the symbol display areas, the gaming system determines a designated set of a plurality of the symbol display areas. In this embodiment, the gaming system does so based at least in part on a proximity of each other symbol display area to the symbol display area at which that triggering symbol is displayed. Put differently, the gaming system uses the location of each other symbol display area relative to the symbol display area at which that triggering symbol is displayed to (at least in part) determine which of the other symbol display areas to include in the designated set of the symbol display areas.
For each symbol display area of the designated set of the symbol display areas, the gaming system replaces the symbol of the first set of symbols displayed at that symbol display area with a randomly determined symbol of a second set of one or more symbols, which may be the same as or different than the first set of symbols. In this embodiment, the gaming system does so by determining a second set of reels each including a plurality of the second set of symbols and displaying the second set of reels spinning and stopping in association with the symbol display areas of the designated set. The gaming system determines any awards based on the displayed symbols and displays any determined awards. The gaming system then ends the play of the slot game.
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 Partial Reel Re-Spin Feature
Various embodiments of the present disclosure provide a gaming system and method providing a slot game including a partial reel re-spin feature. Generally, for a play of the slot game in various embodiments, the gaming system displays a randomly determined plurality of symbols of a first set of symbols at a plurality of symbol display areas (such as by displaying a first set of reels spinning and stopping in association with the symbol display areas). The gaming system makes an award determination based on the displayed symbols. Upon an occurrence of a triggering event (such as the display of a triggering symbol) the gaming system selects a designated set of a plurality of the symbol display areas, and replaces the symbols of the first set of symbols displayed at the symbol display areas of the designated set with symbols from a second set of one or more symbols (such as by displaying a second set of reels spinning and stopping in association with the symbol display areas of the designated set). The gaming system makes another award determination based on the displayed symbols.
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, 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 partial reel re-spin feature. The gaming system displays a plurality of symbol display areas, as indicated by block 102. For each symbol display area, the gaming system displays a randomly determined symbol of a first set of a plurality of symbols at that symbol display area (such as by displaying a first set of reels spinning and stopping in association with the symbol display areas), as indicated by block 104. In this example embodiment, the first set of symbols includes a triggering symbol. The gaming system determines any awards based on the displayed symbols, as indicated by block 106, and displays any determined awards, as indicated by block 108. The gaming system determines if the triggering symbol is displayed at one of the symbol display areas, as indicated by diamond 110.
If the gaming system determines that the triggering symbol is not displayed at any of the symbol display areas, the process 100 (and, in this example embodiment, the play of the slot game) ends. If, on the other hand, the gaming system determines that the triggering symbol is displayed at one of the symbol display areas, the gaming system provides the partial reel re-spin feature. More specifically, if the gaming system determines that the triggering symbol is displayed at one of the symbol display areas, the gaming system determines a designated set of a plurality of the symbol display areas, as indicated by block 112. The gaming system does so based at least in part on a proximity of each other symbol display area to the symbol display area at which that triggering symbol is displayed. Put differently, the gaming system uses the location of each other symbol display area relative to the symbol display area at which that triggering symbol is displayed to (at least in part) determine which of the other symbol display areas to include in the designated set of the symbol display areas.
For each symbol display area of the designated set of the symbol display areas, the gaming system replaces the symbol of the first set of symbols displayed at that symbol display area with a randomly determined symbol of a second set of one or more symbols (such as by displaying a second set of reels spinning and stopping in association with the symbol display areas of the designated set), as indicated by block 114. The second set of symbols may be the same as, or different than, the first set of symbols. The gaming system determines any awards based on the displayed symbols, as indicated by block 116, and displays any determined awards, as indicated by block 118. The process 100 (and, in this example embodiment, the play of the slot game) then ends.
FIGS. 2A, 2B, 2C, 2D, 2E, and 2F illustrate screen shots of one example embodiment of the gaming system of the present disclosure providing the slot game having the partial reel re-spin feature.
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, 2100, 210p, 210q, 210r, 210s, 210t, 210u, 210v, 210w, 210x, 210y, 210z, 210aa, 210bb, 210cc, 210dd, 210ee, 210ff, 210gg, 210hh, 210ii, 210jj, 210kk, 210ll, 210mm, 210nn, 210oo, 210pp, 210qq, 210rr, and 210ss arranged in a 9×5 grid or matrix. The gaming system also displays a first set of a plurality of reels 205a, 205b, 205c, 205d, and 205e, each of which includes a plurality of a first set of a plurality of symbols, in association with the symbol display areas.
More specifically, each reel 205a, 205b, 205c, 205d, and 205e of the first set of reels 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, 210k, 210p, 210u, 210z, 210ee, 210jj, and 210oo; (b) the reel 205b is associated with, and configured to display symbols at, the symbol display areas 210b, 210g, 210l, 210q, 210v, 210aa, 210ff, 210kk, and 210pp; (c) the reel 205c is associated with, and configured to display symbols at, the symbol display areas 210c, 210h, 210m, 210r, 210w, 210bb, 210gg, 210ll, and 210qq; (d) the reel 205d is associated with, and configured to display symbols at, the symbol display areas 210d, 210i, 210n, 210s, 210x, 210cc, 210hh, 210mm, and 210rr; and (e) the reel 205e is associated with, and configured to display symbols at, the symbol display areas 210e, 210j, 2100, 210t, 210y, 210dd, 210ii, 210nn, and 210ss. 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 primary slot game (in credit or currency form).
As noted above, the slot game has a partial reel re-spin feature. In this example embodiment, the gaming system provides the partial reel re-spin feature when a triggering symbol included in the first set of symbols is displayed at one of the symbol display areas following a spin of the first set of reels (i.e., after the gaming system has displayed the first set of reels spinning and stopping such that a symbol of the first set of symbols is displayed at each of the symbol display areas). In this example embodiment, the triggering symbol is a Dollar Sign symbol, though it should be appreciated that any suitable symbol may be the triggering symbol. In this example embodiment, when the triggering symbol is displayed at one of the symbol display areas following a spin of the first set of reels, the gaming system provides the partial reel re-spin feature by: (a) determining a designated set of a plurality of the symbol display areas based at least in part on a proximity of each other symbol display area to the symbol display area at which that triggering symbol is displayed, (b) replacing the symbols of the first set of symbols displayed at the symbol display areas of the designated set of the symbol display areas with symbols from a second set of one or more symbols, and (c) making an award determination based on the displayed symbols.
More specifically, in this example embodiment, when the triggering symbol is displayed at one of the symbol display areas following a spin of the first set of reels, the gaming system determines and includes the following symbol display areas in the designated set of the symbol display areas associated with that triggering symbol: (a) the symbol display area at which that triggering symbol is displayed, (b) each symbol display area adjacent to the symbol display area at which that triggering symbol is displayed, and (c) each symbol display area diagonally adjacent to the symbol display area at which that triggering symbol is displayed. It should thus be appreciated that the symbol display areas in the designated set of the symbol display areas associated with a particular displayed triggering symbol are determined based on the location of each other symbol display area relative to the symbol display area at which that particular triggering symbol is displayed.
Additionally, in this example embodiment, after determining the designated set of the symbol display areas associated with a particular displayed triggering symbol, the gaming system replaces the symbols of the first set of symbols displayed at the symbol display areas of the designated set of the symbol display areas with symbols from the second set of symbols by: (a) determining a second set of one or more reels, each of which includes a plurality of the symbols of the second set of symbols; (b) for each reel of the second set, associating one of more of the symbol display areas of the designated set of the symbol display areas with that reel such that that reel is configured to display a symbol at each of those symbol display areas; and (c) displaying the reel(s) of the second set spinning and stopping such that a symbol of the second set of symbols is displayed at each symbol display area of the designated set of the symbol display areas.
Turning to FIG. 2A, the gaming system receives a deposit of value from a player and credits the player with 2,500 credits (as shown in the credit meter 237). The gaming system displays the following message in the message box 230: “PLACE A WAGER AND PRESS ‘SPIN’ TO SPIN THE REELS! WATCH FOR $ SYMBOLS THAT TRIGGER PARTIAL REEL RE-SPINS AND ADDITIONAL AWARD DETERMINATIONS!”
As shown in FIG. 2B, the gaming system receives a bet of 100 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 100 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 of the first set 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 of the first set such that: (a) Cherry symbol 220a is displayed at the symbol display area 210a, (b) Triple Bar symbol 220b is displayed at the symbol display area 210b, (c) Bar symbol 220c is displayed at the symbol display area 210c, (d) Cherry symbol 220d is displayed at the symbol display area 210d, (e) Triple Cherry symbol 220e is displayed at the symbol display area 210e, (f) Triple Cherry symbol 220f is displayed at the symbol display area 210f, (g) Dollar Sign symbol 220g is displayed at the symbol display area 210g, (h) Cherry symbol 220h is displayed at the symbol display area 210h, (i) Seven symbol 220i is displayed at the symbol display area 210i, (j) Seven symbol 220j is displayed at the symbol display area 210j, (k) Cherry symbol 220k is displayed at the symbol display area 210k, (l) Bar symbol 220l is displayed at the symbol display area 210l, (m) Seven symbol 220m is displayed at the symbol display area 210m, (n) Double Bar symbol 220n is displayed at the symbol display area 210n, (o) Double Bar symbol 220o is displayed at the symbol display area 210o, (p) Cherry symbol 220p is displayed at the symbol display area 210p, (q) Triple Bar symbol 220q is displayed at the symbol display area 210q, (r) Cherry symbol 220r is displayed at the symbol display area 210r, (s) Bar symbol 220s is displayed at the symbol display area 210s, (t) Bar symbol 220t is displayed at the symbol display area 210t, (u) Triple Bar symbol 220u is displayed at the symbol display area 210u, (v) Bar symbol 220v is displayed at the symbol display area 210v, (w) Dollar Sign symbol 220w is displayed at the symbol display area 210w, (x) Triple Bar symbol 220x is displayed at the symbol display area 210x, (y) Triple Cherry symbol 220y is displayed at the symbol display area 210y, (z) Bar symbol 220z is displayed at the symbol display area 210z, (aa) Triple Cherry symbol 220aa is displayed at the symbol display area 210aa, (bb) Cherry symbol 220bb is displayed at the symbol display area 210bb, (cc) Seven symbol 220ee is displayed at the symbol display area 210cc, (dd) Cherry symbol 220dd is displayed at the symbol display area 210dd, (ee) Bar symbol 220ee is displayed at the symbol display area 210ee, (ff) Bar symbol 220ff is displayed at the symbol display area 210ff, (gg) Triple Cherry symbol 220gg is displayed at the symbol display area 210gg, (hh) Seven symbol 220hh is displayed at the symbol display area 210hh, (ii) Cherry symbol 220ii is displayed at the symbol display area 210ii, (jj) Cherry symbol 220jj is displayed at the symbol display area 210jj, (kk) Double Bar symbol 220kk is displayed at the symbol display area 210kk, (ll) Cherry symbol 220ll is displayed at the symbol display area 210ll, (mm) Triple Cherry symbol 220mm is displayed at the symbol display area 210mm, (nn) Seven symbol 220nn is displayed at the symbol display area 210nn, (oo) Cherry symbol 220oo is displayed at the symbol display area 210oo, (pp) Double Bar symbol 220pp is displayed at the symbol display area 210pp, (qq) Seven symbol 220qq is displayed at the symbol display area 210qq, (rr) Bar symbol 220rr is displayed at the symbol display area 210rr, and (ss) Bar symbol 220ss is displayed at the symbol display area 210ss. 
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 example embodiment, the gaming system determines that no winning symbol combinations are displayed at the symbol display areas associated with any of the wagered-on paylines.
The gaming system determines whether the Dollar Sign symbol (i.e., the triggering symbol in this example embodiment) is displayed at any of the symbol display areas. The gaming system determines that: (a) the Dollar Sign symbol 220g is displayed at the symbol display area 210g, and (b) the Dollar Sign symbol 220w is displayed at the symbol display area 210w. The gaming system displays the following message in the message box 230: “SORRY, NO WINNING SYMBOL COMBINATIONS ARE DISPLAYED. BUT TWO $ SYMBOLS ARE DISPLAYED! PLEASE WAIT WHILE THE REELS ARE PARTIALLY RE-SPUN AND AN ADDITIONAL AWARD DETERMINATION IS MADE!”
As shown in FIG. 2D, for each displayed triggering symbol, the gaming system determines a designated set of the symbol display areas. Specifically, for the Dollar Sign symbol 220g, the gaming system determines a designated set of the symbol display areas 240a including: (i) the symbol display area 210g (i.e., the symbol display area at which the Dollar Sign symbol 220g is displayed); (ii) the symbol display areas 210b, 210f, 210h, and 210l (i.e., each symbol display area adjacent to the symbol display area 210g at which the Dollar Sign symbol 220g is displayed); and (iii) the symbol display areas 210a, 210c, 210k, and 210m (i.e., each symbol display area diagonally adjacent to the symbol display area 210g at which the Dollar Sign symbol 220g is displayed). Similarly, for the Dollar Sign symbol 220w, the gaming system determines a designated set of the symbol display areas 240b including: (i) the symbol display area 210w (i.e., the symbol display area at which the Dollar Sign symbol 220w is displayed); (ii) the symbol display areas 210r, 210v, 210x, and 210bb (i.e., each symbol display area adjacent to the symbol display area 210w at which the Dollar Sign symbol 220w is displayed); and (iii) the symbol display areas 210q, 210s, 210aa, and 210cc (i.e., each symbol display area diagonally adjacent to the symbol display area 210w at which the Dollar Sign symbol 220w is displayed). In this example embodiment, the gaming system highlights the designated sets of the symbol display areas 240a and 240b via a dark border, though it should be appreciated that the gaming system may do so (or not) in any other suitable manner. The gaming system displays the following message in the message box 230: “THE PORTIONS OF THE REELS THAT WILL BE RE-SPUN ARE HIGHLIGHTED . . . .
As explained above, in this example embodiment, after determining the designated sets of the symbol display areas, for each of the designated sets of the symbol display areas, the gaming system determines a second set of reels and associates each reel of the second set of reels with one or more of the symbol display areas of that designated set of the symbol display areas. In this example embodiment, the second set of symbols is the same as the first set of symbols, and each of the reels of the second set of reels includes a plurality of the symbols of the second set of symbols. In this example embodiment, each individual designated set of the symbol display areas is associated with an individual second set of reels.
Specifically, respect to the designated set of the symbol display areas 240a associated with the Dollar Sign symbol 220g, the gaming system: (a) determines a reel 255a, which is the same as the reel 205a, and associates the reel 255a with the symbol display areas 210a, 210f, and 210k of the designated set of the symbol display areas 240a such that the reel 255a is configured to display symbols at those symbol display areas; (b) determines a reel 255b, which is the same as the reel 205b, and associates the reel 255b with the symbol display areas 210b, 210g, and 210l of the designated set of the symbol display areas 240a such that the reel 255b is configured to display symbols at those symbol display areas; and (c) determines a reel 255c, which is the same as the reel 205c, and associates the reel 255c with the symbol display areas 210c, 210h, and 210m of the designated set of the symbol display areas 240a such that the reel 255c is configured to display symbols at those symbol display areas. Thus, in this example embodiment, the second set of reels associated with the designated set of the symbol display areas 240a includes the reels 255a, 255b, and 255c. 
With respect to the designated set of the symbol display areas 240b associated with the Dollar Sign symbol 220w, the gaming system: (a) determines a reel 265b, which is the same as the reel 205b, and associates the reel 265b with the symbol display areas 210q, 210v, and 210aa of the designated set of the symbol display areas 240b such that the reel 265b is configured to display symbols at those symbol display areas; (b) determines a reel 265c, which is the same as the reel 205c, and associates the reel 265c with the symbol display areas 210r, 210w, and 210bb of the designated set of the symbol display areas 240b such that the reel 265c is configured to display symbols at those symbol display areas; and (c) determines a reel 265d, which is the same as the reel 205d, and associates the reel 265d with the symbol display areas 210s, 210x, and 210cc of the designated set of the symbol display areas 240b such that the reel 265d is configured to display symbols at those symbol display areas. Thus, in this example embodiment, the second set of reels associated with the designated set of the symbol display areas 240b includes the reels 265b, 265c, and 265d. 
It should thus be appreciated that, in this example embodiment, for a particular designated set of the symbol display areas, the second set of reels that the gaming system employs for that designated set of the symbol display areas is the same as the first set of reels the gaming system employed for the symbol display areas of that designated set of the symbol display areas.
As shown in FIG. 2E, the gaming system: (a) displays the reels 255a, 255b, 255c of the second set of reels associated with the designated set of the symbol display areas 240a spinning in association with the designated set of the symbol display areas 240a; (b) displays the reels 265b, 265c, and 265d of the second set of reels associated with the designated set of the symbol display areas 240b spinning in association with the designated set of the symbol display areas 240b; and (c) does not display any reels spinning in association with the symbol display areas not included in any of the designated sets of the symbol display areas. That is, in this example embodiment, the gaming system does not replace any symbols of the first set of symbols displayed at the symbol display areas that are not included in either of the designated sets of the symbol display areas. The gaming system displays the following message in the message box 230: “PLEASE WAIT WHILE THE HIGHLIGHTED PORTIONS OF THE REELS ARE RE-SPUN . . . ”
As illustrated in FIG. 2F, with respect to the designated set of the symbol display areas 240a, the gaming system stops the reels 255a, 255b, and 255c of the second set of reels associated with the designated set of the symbol display areas 240a from spinning such that: (a) the Bar symbol 221a is displayed at the symbol display area 210a, (b) the Double Bar symbol 221b is displayed at the symbol display area 210b, (c) the Cherry symbol 221c is displayed at the symbol display area 210c, (d) the Seven symbol 221f is displayed at the symbol display area 210f, (e) the Seven symbol 221g is displayed at the symbol display area 210g, (f) the Seven symbol 221h is displayed at the symbol display area 210h, (g) the Bar symbol 221k is displayed at the symbol display area 210k, (h) the Cherry symbol 221l is displayed at the symbol display area 210l, and (i) the Seven symbol 221m is displayed at the symbol display area 210m. 
Additionally, with respect to the designated set of the symbol display areas 240b, the gaming system stops the reels 265b, 265c, and 265d of the second set of reels associated with the designated set of the symbol display areas 240b from spinning such that: (a) the Cherry symbol 221q is displayed at the symbol display area 210q, (b) the Cherry symbol 221r is displayed at the symbol display area 210r, (c) the Seven symbol 221s is displayed at the symbol display area 210s, (d) the Bar symbol 221v is displayed at the symbol display area 210v, (e) the Bar symbol 221w is displayed at the symbol display area 210w, (f) the Seven symbol 221x is displayed at the symbol display area 210x, (g) the Bar symbol 221aa is displayed at the symbol display area 210aa, (h) the Bar symbol 221bb is displayed at the symbol display area 210bb, and (i) the Triple Cherry symbol 221cc is displayed at the symbol display area 210cc. 
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 associated with the slot game are displayed at the symbol display areas associated with any of the wagered-on paylines. In this example embodiment, the gaming system determines: (a) an award of 10,000 credits associated with the Seven-Seven-Seven-Seven-Seven winning symbol combination displayed at the symbol display areas associated with a payline 215a; (b) an award of 30 credits associated with the Cherry-Cherry-Cherry winning symbol combination displayed at the symbol display areas associated with a payline 215b; (c) an award of 10 credits associated with the Bar-Bar-Bar winning symbol combination displayed at the symbol display areas associated with a payline 215c; and (d) an award of 10 credits associated with the Bar-Bar-Bar winning symbol combination displayed at the symbol display areas associated with a payline 215d. The gaming system displays the total award of 10,050 credits in the award meter 238 and updates the player's credit meter 237 to reflect the total award of 10,050 credits.
Variations
It should be appreciated that the gaming system may determine which symbol display areas to include in the designated set of the symbol display areas in any suitable manner.
In various embodiments, upon an occurrence of the triggering event, the gaming system randomly determines which particular symbol display areas to include in the designated set of the symbol display areas. In one such embodiment, a quantity of the symbol display areas to include in the designated set of the symbol display areas is predetermined. In another such embodiment, the gaming system randomly determines the quantity of the symbol display areas to include in the designated set of the symbol display areas.
In certain embodiments, upon an occurrence of the triggering event, the gaming system determines which symbol display areas to include in the designated set of the symbol display areas based at least in part on a proximity of each other symbol display area to a designated one of the symbol display areas (such as a symbol display area displaying a triggering symbol). In one such embodiment, symbol display areas relatively close to the designated symbol display area have a relatively higher probability of being included in the designated set of the symbol display areas than symbol display areas relatively far from the designated symbol display area. Put differently, in this embodiment, the gaming system is more likely to select a symbol display area that is relatively close to the designated symbol display area for inclusion in the designated set of the symbol display areas than a symbol display area that is relatively far from the designated symbol display area.
In another such embodiment, symbol display areas relatively close to the designated symbol display area have a relatively lower probability of being included in the designated set of the symbol display areas than symbol display areas relatively far from the designated symbol display area. Put differently, in this embodiment, the gaming system is more likely to select a symbol display area that is relatively far from the designated symbol display area for inclusion in the designated set of the symbol display areas than a symbol display area that is relatively close to the designated symbol display area.
In various embodiments, upon an occurrence of the triggering event, the gaming system determines which symbol display areas to include in the designated set of the symbol display areas based at least in part on one of a plurality of different patterns. In one such embodiment, upon an occurrence of the triggering event, the gaming system includes the symbol display areas included in a same row as the symbol display area displaying the designated symbol in the designated set of the symbol display areas. In another such embodiment, upon an occurrence of the triggering event, the gaming system includes the symbol display areas included in a same column as the symbol display area displaying the designated symbol in the designated set of the symbol display areas In another such embodiment, upon an occurrence of the triggering event, the gaming system includes the symbol display areas included in a same row and/or a same column as the symbol display area displaying the designated symbol in the designated set of the symbol display areas. In another such embodiment, upon an occurrence of the triggering event, the gaming system includes the symbol display areas adjacent to the symbol display area displaying the designated symbol in the designated set of the symbol display areas. In another such embodiment, upon an occurrence of the triggering event, the gaming system includes the symbol display areas diagonally adjacent to the symbol display area displaying the designated symbol in the designated set of the symbol display areas.
In certain embodiments, the slot game includes a plurality of different triggering symbols. In these embodiments, upon an occurrence of the triggering event, the gaming system determines which symbol display areas to include in the designated set of the symbol display areas based on which particular triggering symbol is displayed. For instance, if a first triggering symbol is displayed, the gaming system employs a first pattern to determine the designated set of the symbol display areas, but if a second triggering symbol is displayed, the gaming system employs a second different pattern to determine the designated set of the symbol display areas.
In certain embodiments, upon an occurrence of the triggering event, the gaming system enables the player to select at least one symbol display area to include in the designated set of the symbol display areas. In other embodiments, the gaming system determines which symbol display areas to include in the designated set of the symbol display areas based, at least in part, on the player's wager amount.
In certain embodiments, when two triggering symbols are displayed in different rows and different columns, the two triggering symbols define opposing corners of the designated set of the symbol display areas. FIGS. 3A and 3B illustrate screen shots of one such example embodiment of the gaming system of the present disclosure. Specifically, FIG. 3A illustrates a screen shot of the gaming system following a spin of the first set of reels. Here, the gaming system displays, in pertinent part, a Dollar Sign symbol 320v (i.e., a triggering symbol in this example embodiment) at the symbol display area 310v and a Dollar Sign symbol 320mm at the symbol display area 310mm. As shown in FIG. 3B, in this example embodiment, the gaming system determines a designated set of the symbol display area 340a including the symbol display areas 310v and 310mm, which define opposing corners of the designated set of the symbol display areas 340a. 
In certain such embodiments, when the two triggering symbols are displayed at the symbol display areas that define the opposing corners of the entire set of the symbol display areas (such as the symbol display areas 310a and 310ss shown in FIGS. 3A and 3B), the gaming system prevents the designated set of the symbol display areas from including all of the symbol display areas. In these embodiments, the gaming system selects a subset of the symbol display areas (such as randomly or based on any other suitable factor) to include in the designated set of the symbol display areas.
The triggering event that causes the gaming system to provide the partial reel re-spin feature may be any suitable event, such as (but not limited to): (a) the display of a triggering symbol in one of the symbol display areas following a spin of the first or second set of reels; (b) the display of a designated symbol combination following a spin of the first or second set of reels; (c) the display of a winning symbol combination following a spin of the first or second set of reels; (d) the gaming system providing the player a designated award (such as a progressive award or a jackpot award); (e) a total quantity of plays of the slot game played by the player during a gaming session reaching a designated quantity of plays; (f) the gaming system receiving a deposit of value to fund the gaming system at least a designated quantity of times during a gaming session; (g) a total amount wagered by the player during a gaming session reaching a designated amount wagered; (h) a total amount of credits or currency won by the player during a gaming session reaching a designated amount won; (i) a total amount of credits or currency lost by the player during a gaming session reaching a designated amount lost; (j) a time of day reaching a designated time of day; (k) a length of a gaming session reaching a designated length of time; (l) a play of a bonus game having not been provided within a designated amount of time during a gaming session; (m) a play of a bonus game having not been provided within a designated quantity of plays of the slot game during a gaming session; (n) the player achieving a designated quantity of consecutive winning outcomes during a gaming session; (o) the player achieving a designated quantity of consecutive losing outcomes during a gaming session; (p) a total quantity of winning outcomes achieved by the player during a gaming session reaching a designated quantity; (q) a total quantity of losing outcomes achieved by the player during a gaming session reaching a designated quantity; (r) a total amount of coin-in during a gaming session reaching a designated quantity; (s) a credit balance of the player reaching a designated credit balance; (t) a total amount of currency deposited by the player during a gaming session reaching a designated amount; (u) a change in frequency of play reaching a designated amount; (v) a ticket, coupon, or promotion being inserted or otherwise entered (such as by typing in a promotion code or scanning a barcode); (w) a designated quantity of credits being transferred onto the gaming system; (x) player tracking points being converted into one or more credits; and/or (y) a triggering event occurring during play of a community or multiplayer game.
FIGS. 4A and 4B illustrate screen shots of another example embodiment of the gaming system of the present disclosure configured to provide the partial reel re-spin feature when: (a) a designated symbol combination is displayed, and (b) a triggering symbol is displayed. In other words, in this example embodiment, the triggering event occurs when both the designated symbol combination and the triggering symbol are displayed following a spin of the first set of reels, and does not occur when only one of or neither of the designated symbol combination and the triggering symbol is displayed following a spin of the first set of reels. In this example embodiment, the designated symbol combination is any winning symbol combination and the triggering symbol is the Dollar Sign symbol.
FIG. 4A illustrates a screen shot of the gaming system following a spin of the first set of reels. In this example embodiment, following the spin of the first set of reels, the gaming system displays: (a) Bar symbol 420a is displayed at the symbol display area 410a, (b) Triple Bar symbol 420b is displayed at the symbol display area 410b, (c) Cherry symbol 420c is displayed at the symbol display area 410c, (d) Triple Cherry symbol 420d is displayed at the symbol display area 410d, (e) Triple Cherry symbol 420e is displayed at the symbol display area 410e, (f) Seven symbol 420f is displayed at the symbol display area 410f, (g) Seven symbol 420g is displayed at the symbol display area 410g, (h) Seven symbol 420h is displayed at the symbol display area 410h, (i) Seven symbol 420i is displayed at the symbol display area 410i, (j) Seven symbol 420j is displayed at the symbol display area 410j, (k) Bar symbol 420k is displayed at the symbol display area 410k, (l) Bar symbol 420l is displayed at the symbol display area 410l, (m) Cherry symbol 420m is displayed at the symbol display area 410m, (n) Seven symbol 420n is displayed at the symbol display area 410n, (o) Triple Bar symbol 4200 is displayed at the symbol display area 4100, (p) Seven symbol 420p is displayed at the symbol display area 410p, (q) Bar symbol 420q is displayed at the symbol display area 410q, (r) Cherry symbol 420r is displayed at the symbol display area 410r, (s) Triple Cherry symbol 420s is displayed at the symbol display area 410s, (t) Bar symbol 420t is displayed at the symbol display area 410t, (u) Cherry symbol 420u is displayed at the symbol display area 410u, (v) Dollar Sign symbol 420v is displayed at the symbol display area 410v, (w) Triple Cherry symbol 420w is displayed at the symbol display area 410w, (x) Triple Bar symbol 420x is displayed at the symbol display area 410x, (y) Bar symbol 420y is displayed at the symbol display area 410y, (z) Triple Cherry symbol 420z is displayed at the symbol display area 410z, (aa) Cherry symbol 420aa is displayed at the symbol display area 410aa, (bb) Triple Bar symbol 420bb is displayed at the symbol display area 410bb, (cc) Triple Bar symbol 420ee is displayed at the symbol display area 410cc, (dd) Double Bar symbol 420dd is displayed at the symbol display area 410dd, (ee) Cherry symbol 420ee is displayed at the symbol display area 410ee, (ff) Triple Cherry symbol 420ff is displayed at the symbol display area 410ff, (gg) Triple Bar symbol 420gg is displayed at the symbol display area 410gg, (hh) Bar symbol 420hh is displayed at the symbol display area 410hh, (ii) Bar symbol 420ii is displayed at the symbol display area 410ii, (jj) Seven symbol 420jj is displayed at the symbol display area 410jj, (kk) Seven symbol 420kk is displayed at the symbol display area 410kk, (ll) Triple Bar symbol 420ll is displayed at the symbol display area 410ll, (mm) Dollar Sign symbol 420mm is displayed at the symbol display area 410mm, (nn) Double Bar symbol 420nn is displayed at the symbol display area 410nn, (oo) Bar symbol 42000oo is displayed at the symbol display area 410oo, (pp) Cherry symbol 420pp is displayed at the symbol display area 410pp, (qq) Cherry symbol 420qq is displayed at the symbol display area 410qq, (rr) Double Bar symbol 420rr is displayed at the symbol display area 410rr, and (ss) Double Bar symbol 420ss is displayed at the symbol display area 410ss. 
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 associated with the slot game are displayed at the symbol display areas associated with any of the wagered-on paylines. In this example embodiment, the gaming system determines an award of 10,000 credits associated with the Seven-Seven-Seven-Seven-Seven winning symbol combination displayed at the symbol display areas associated with a payline 415a. The gaming system displays the award of 10,000 credits in the award meter 438 and updates the player's credit meter 437 to reflect the award of 10,000 credits.
The gaming system determines whether the triggering event occurred by, in this example embodiment, determining whether both: (a) any winning symbol combination (i.e., a designated symbol combination in this example embodiment), and (b) at least one Dollar Sign symbol (i.e., the triggering symbol in this example embodiment) are displayed at the symbol display areas. Here, the gaming system determines that: (a) the Seven-Seven-Seven-Seven-Seven winning symbol combination, and (b) the Dollar Sign symbol 420v is displayed at the symbol display area 410v and the Dollar Sign symbol 420mm is displayed at the symbol display area 410mm. The gaming system displays the following message in the message box 430: “CONGRATULATIONS, YOU WIN 10,000 CREDITS!. TWO $ SYMBOLS AND A WINNING SYMBOL COMBINATION ARE DISPLAYED! PLEASE WAIT WHILE THE REELS ARE PARTIALLY RE-SPUN AND AN ADDITIONAL AWARD DETERMINATION IS MADE!”
As shown in FIG. 4B, for each displayed triggering symbol, the gaming system determines a designated set of the symbol display areas. Specifically, for the Dollar Sign symbol 420v, the gaming system determines a designated set of the symbol display areas 440a including: (i) the symbol display area 410v (i.e., the symbol display area at which the Dollar Sign symbol 420v is displayed); (ii) the symbol display areas 410q, 410u, 410w, and 410aa (i.e., each symbol display area adjacent to the symbol display area 410v at which the Dollar Sign symbol 420v is displayed); and (iii) the symbol display areas 410p, 410r, 410z, and 410bb (i.e., each symbol display area diagonally adjacent to the symbol display area 410v at which the Dollar Sign symbol 420v is displayed). Similarly, for the Dollar Sign symbol 420mm, the gaming system determines a designated set of the symbol display areas 440b including: (i) the symbol display area 410mm (i.e., the symbol display area at which the Dollar Sign symbol 420mm is displayed); (ii) the symbol display areas 410hh, 410ll, 410nn, and 410rr (i.e., each symbol display area adjacent to the symbol display area 410mm at which the Dollar Sign symbol 420mm is displayed); and (iii) the symbol display areas 410gg, 410ii, 410qq, and 410ss (i.e., each symbol display area diagonally adjacent to the symbol display area 410mm at which the Dollar Sign symbol 420mm is displayed). The gaming system displays the following message in the message box 430: “THE PORTIONS OF THE REELS THAT WILL BE RE-SPUN ARE HIGHLIGHTED . . . ”
In various embodiments, when a designated symbol combination is displayed following a spin of the first set of the reels, the gaming system: (a) designates one of the symbols of the first set of symbols as a triggering symbol, and (b) determines whether the triggering symbol is displayed at any of the symbol display areas other than the symbol display areas displaying the designated symbol combination. If the triggering symbol is displayed at a symbol display area other than the symbol display areas displaying the designated symbol combination, the gaming system provides the partial reel re-spin feature. In one such embodiment, the gaming system determines which of the symbols of the first set of symbols to designate as the triggering symbol based at least in part on the displayed designated symbol combination. For instance, in one example embodiment in which the designated symbol combination is any winning symbol combination and a winning symbol combination is displayed following a spin of the first set of reels, the gaming system designates the symbol of that winning symbol combination as the triggering symbol.
FIGS. 5A and 5B illustrate screen shots of one such example embodiment of the gaming system of the present disclosure configured to provide the partial reel re-spin feature when: (a) a designated symbol combination is displayed, and (b) a triggering symbol is displayed at a symbol display area other than the symbol display areas displaying the designated symbol combination. In other words, in this example embodiment, the triggering event occurs when the designated symbol combination and the triggering symbol are displayed at distinct symbol display areas following a spin of the first set of reels. In this example embodiment, the designated symbol combination is any winning symbol combination, and the gaming system determines which of the symbols of the first set of symbols to designate as the triggering symbol based at least in part on the displayed designated symbol combination.
FIG. 5A illustrates a screen shot of the gaming system following a spin of the first set of reels. In this example embodiment, following the spin of the first set of reels, the gaming system displays: (a) Bar symbol 520a is displayed at the symbol display area 510a, (b) Triple Bar symbol 520b is displayed at the symbol display area 510b, (c) Cherry symbol 520c is displayed at the symbol display area 510c, (d) Triple Cherry symbol 520d is displayed at the symbol display area 510d, (e) Triple Cherry symbol 520e is displayed at the symbol display area 510e, (f) Seven symbol 520f is displayed at the symbol display area 510f, (g) Seven symbol 520g is displayed at the symbol display area 510g, (h) Seven symbol 520h is displayed at the symbol display area 510h, (i) Seven symbol 520i is displayed at the symbol display area 510i, (j) Seven symbol 520j is displayed at the symbol display area 510j, (k) Bar symbol 520k is displayed at the symbol display area 510k, (l) Bar symbol 520l is displayed at the symbol display area 510l, (m) Cherry symbol 520m is displayed at the symbol display area 510m, (n) Double Bar symbol 520n is displayed at the symbol display area 510n, (o) Bar symbol 520o is displayed at the symbol display area 5100, (p) Cherry symbol 520p is displayed at the symbol display area 510p, (q) Seven symbol 520q is displayed at the symbol display area 510q, (r) Triple Bar symbol 520r is displayed at the symbol display area 510r, (s) Triple Bar symbol 520s is displayed at the symbol display area 510s, (t) Cherry symbol 520t is displayed at the symbol display area 510t, (u) Bar symbol 520u is displayed at the symbol display area 510u, (v) Bar symbol 520v is displayed at the symbol display area 510v, (w) Triple Cherry symbol 520w is displayed at the symbol display area 510w, (x) Double Bar symbol 520x is displayed at the symbol display area 510x, (y) Double Bar symbol 520y is displayed at the symbol display area 510y, (z) Triple Bar symbol 520z is displayed at the symbol display area 510z, (aa) Bar symbol 520aa is displayed at the symbol display area 510aa, (bb) Cherry symbol 520bb is displayed at the symbol display area 510bb, (cc) Triple Bar symbol 520cc is displayed at the symbol display area 510cc, (dd) Cherry symbol 520dd is displayed at the symbol display area 510dd, (ee) Bar symbol 520ee is displayed at the symbol display area 510ee, (ff) Seven symbol 520ff is displayed at the symbol display area 510ff, (gg) Double Bar symbol 520gg is displayed at the symbol display area 510gg, (hh) Triple Bar symbol 520hh is displayed at the symbol display area 510hh, (ii) Bar symbol 520ii is displayed at the symbol display area 510ii, (jj) Cherry symbol 520jj is displayed at the symbol display area 510jj, (kk) Cherry symbol 520kk is displayed at the symbol display area 510kk, (ll) Bar symbol 52011 is displayed at the symbol display area 510ll, (mm) Triple Cherry symbol 520mm is displayed at the symbol display area 510mm, (nn) Seven symbol 520nn is displayed at the symbol display area 510nn, (oo) Cherry symbol 520oo is displayed at the symbol display area 510oo, (pp) Triple Cherry symbol 520pp is displayed at the symbol display area 510pp, (qq) Triple Bar symbol 520qq is displayed at the symbol display area 510qq, (rr) Bar symbol 520rr is displayed at the symbol display area 510rr, and (ss) Bar symbol 520ss is displayed at the symbol display area 510ss. 
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 associated with the slot game are displayed at the symbol display areas associated with any of the wagered-on paylines. In this example embodiment, the gaming system determines an award of 10,000 credits associated with the Seven-Seven-Seven-Seven-Seven winning symbol combination displayed at the symbol display areas associated with a payline 515a. The gaming system displays the award of 10,000 credits in the award meter 538 and updates the player's credit meter 537 to reflect the award of 10,000 credits.
The gaming system designates the Seven symbol, which is the symbol included in the displayed winning symbol combination, as the triggering symbol. The gaming system determines whether the triggering event occurred by, in this example embodiment, determining whether the Seven symbol (i.e., the triggering symbol in this example embodiment) is displayed at a symbol display area other than the symbol display areas displaying the winning symbol combination. Here, the gaming system determines that the Seven symbol 520q is displayed at the symbol display area 510q (which is not one of the symbol display areas at which one of the Seven symbols of the winning symbol combination is displayed), the Seven symbol 520ff is displayed at the symbol display area 510ff (which is not one of the symbol display areas at which one of the Seven symbols of the winning symbol combination is displayed), and the Seven symbol 520nn is displayed at the symbol display area 510nn (which is not one of the symbol display areas at which one of the Seven symbols of the winning symbol combination is displayed). The gaming system displays the following message in the message box 530: “CONGRATULATIONS, YOU WIN 10,000 CREDITS!. THREE ADDITIONAL 7 SYMBOLS ARE DISPLAYED. PLEASE WAIT WHILE THE REELS ARE PARTIALLY RE-SPUN AND AN ADDITIONAL AWARD DETERMINATION IS MADE!”
As shown in FIG. 5B, for each displayed triggering symbol, the gaming system determines a designated set of the symbol display areas.

FIGS. 7A and 7B illustrate screen shots of another such example embodiment of the gaming system of the present disclosure configured to merge designated sets of the symbol display areas that each include at least one same one of the symbol display areas.
FIG. 7A illustrates a screen shot of the gaming system following a spin of the first set of reels. In this example embodiment, the gaming system has determined: (a) a designated set of the symbol display areas 740a associated with the displayed triggering symbol 720g and including the symbol display areas 710a, 710b, 710c, 710f, 710g, 710h, 710k, 710l, and 710m; (b) a designated set of the symbol display areas 740b associated with the displayed triggering symbol 720r and including the symbol display areas 710l, 710m, 710n, 710q, 710r, 710s, 710v, 710w, and 710x; and (c) a designated set of the symbol display areas 740c associated with the displayed triggering symbol 720aa and including the symbol display areas 710u, 710v, 710w, 710z, 710aa, 710bb, 710ee, 710ff, and 710gg. 
The gaming system determines whether any of the designated sets of the symbol display areas include at least one same one of the symbol display areas. Here, the gaming system determines that: (a) the designated set of the symbol display areas 740a and the designated set of the symbol display areas 740b each include the symbol display areas 710l and 710m, and (b) the designated set of the symbol display areas 740b and 740c each include the symbol display areas 710v and 710w. Accordingly, the gaming system determines to merge the designated set of the symbol display areas 740b with both the designated set of the symbol display areas 740a and the designated set of the symbol display areas 740c, and displays the following message in the message box 730: “PLEASE WAIT WHILE THE OVERLAPPING SETS OF SYMBOL DISPLAY AREAS ARE MERGED . . . ”
As shown in FIG. 7B, the gaming system merges the designated sets of the symbol display areas 740a, 740b, and 740c into a single merged set of the symbol display areas 740d including the symbol display areas 710a, 710b, 710c, 710f, 710g, 710h, 710k, 710l, 710m, 710n, 710q, 710r, 710s, 710u, 710v, 710w, 710x, 710z, 710aa, 710bb, 710ee, 710ff, and 710gg. The gaming system displays the following message in the message box 730: “THE PORTIONS OF THE REELS THAT WILL BE RE-SPUN ARE HIGHLIGHTED . . . ”
In certain embodiments, the gaming system merges designated sets of the symbol display areas that share a common border into a single merged designated set of the symbol display areas. In other words, when at least one symbol display area of a first designated set of the symbol display areas is adjacent to (or, in other embodiments, adjacent symbol display areas or diagonally adjacent symbol display areas) at least one symbol display area of a second designated set of the symbol display areas, the gaming system merges those designated sets of the symbol display areas to create a single, merged designated set of the symbol display areas.
FIGS. 8A and 8B illustrate screen shots of another such example embodiment of the gaming system of the present disclosure configured to merge designated sets of the symbol display areas that share a common border into a single merged designated set of the symbol display areas.
FIG. 8A illustrates a screen shot of the gaming system following a spin of the first set of reels. In this example embodiment, the gaming system has determined: (a) a designated set of the symbol display areas 840a associated with the displayed triggering symbol 820v and including the symbol display areas 810p, 810q, 810r, 810u, 810v, 810w, 810z, 810aa, and 810bb; and (b) a designated set of the symbol display areas 840b associated with the displayed triggering symbol 820mm and including the symbol display areas 810gg, 810hh, 810ii, 810ll, 810mm, 810nn, 810qq, 810rr, and 810ss. 
The gaming system determines whether at least one symbol display area of the designated set of the symbol display areas 840a is adjacent to at least one symbol display area of the designated set of the symbol display areas 840b. Here, the gaming system determines that the symbol display area 810bb of the designated set of the symbol display areas 840a is adjacent to the symbol display area 810gg of the designated set of the symbol display areas 840b. Accordingly, the gaming system determines to merge the designated set of the symbol display areas 840a and 840b, and displays the following message in the message box 830: “PLEASE WAIT WHILE THE SETS OF SYMBOL DISPLAY AREAS SHARING A COMMON BORDER ARE MERGED . . . ”
As shown in FIG. 8B, the gaming system merges the designated sets of the symbol display areas 840a and 840b into a single merged set of the symbol display areas 840c including the symbol display areas 810p, 810q, 810r, 810u, 810v, 810w, 810z, 810aa, 810bb, 810gg, 810hh, 810ii, 810ll, 810mm, 810nn, 810qq, 810rr, and 810ss. The gaming system displays the following message in the message box 830: “THE PORTIONS OF THE REELS THAT WILL BE RE-SPUN ARE HIGHLIGHTED . . . ”
In certain embodiments, when the gaming system determines a designated set of the symbol display areas upon the occurrence of the triggering event, the gaming system determines whether to display a designated symbol, such as a Wild symbol, at one or more of the symbol display areas of that designated set of the symbol display areas. For instance, in one example embodiment, after determining a designated set of the symbol display areas following the occurrence of the triggering event, the gaming system randomly determines (such as via a paytable-driven random determination), for each symbol display area in the designated set of the symbol display areas, whether to replace the symbol of the first set of symbols displayed at that symbol display area with a Wild symbol. Thereafter, for each symbol display area of the designated set of the symbol display areas at which a Wild symbol is not displayed, the gaming system replaces the symbol of the first set of symbols displayed at that symbol display area with a symbol of the second set of symbols.
In other embodiments, when the gaming system determines a designated set of the symbol display areas upon the occurrence of the triggering event, the gaming system determines whether to display a designated symbol, such as a Wild symbol, at one or more of the symbol display areas, including the symbol display areas not included in the designated set of the symbol display areas. For instance, in one example embodiment, after determining a designated set of the symbol display areas following the occurrence of the triggering event, the gaming system randomly determines (such as via a paytable-driven random determination), for each symbol display area (including those not included in the designated set of the symbol display areas), whether to replace the symbol of the first set of symbols displayed at that symbol display area with a Wild symbol. Thereafter, for each symbol display area of the designated set of the symbol display areas at which a Wild symbol is not displayed, the gaming system replaces the symbol of the first set of symbols displayed at that symbol display area with a symbol of the second set of symbols.
In various embodiments, the second set of one or more symbols only includes Wild symbols. Thus, in these embodiments, when the gaming system determines a designated set of the symbol display areas upon the occurrence of the triggering event, for each symbol display area in the designated set of the symbol display areas, the gaming system replaces the symbol of the first set of symbols displayed at that symbol display area with a Wild symbol.
In certain embodiments, the partial reel re-spin feature also includes an expanding Wilds feature. In one such embodiment, when the gaming system determines a designated set of the symbol display areas upon the occurrence of the triggering event, the gaming system replaces the symbols of the first set displayed at each of a column of the symbol display areas of the designated set (such as the column of the symbol display areas of the designated set including the symbol display area at which the triggering symbol is displayed) with Wild symbols. In another such embodiment, when the gaming system determines a designated set of the symbol display areas upon the occurrence of the triggering event, the gaming system replaces the symbols of the first set displayed at each of a row of the symbol display areas of the designated set (such as the row of the symbol display areas of the designated set including the symbol display area at which the triggering symbol is displayed) with Wild symbols. In another such embodiment, when the gaming system determines a designated set of the symbol display areas upon the occurrence of the triggering event, the gaming system replaces the symbols of the first set displayed at each of a column of the symbol display areas (such as the column of the symbol display areas including the symbol display area at which the triggering symbol is displayed) with Wild symbols. In another such embodiment, when the gaming system determines a designated set of the symbol display areas upon the occurrence of the triggering event, the gaming system replaces the symbols of the first set displayed at each of a row of the symbol display areas (such as the row of the symbol display areas including the symbol display area at which the triggering symbol is displayed) with Wild symbols.
In various embodiments, the gaming system provides the player an award (such as an award or monetary credits or any other suitable award) upon an occurrence of the triggering event in addition to providing the partial reel re-spin feature. In one such embodiment, the gaming system determines the award based on the size of the designated set of the symbol display areas (e.g., based on how many symbol display areas are included in the designated set).
As noted above, in certain embodiments, for a particular designated set of the plurality of symbol display areas, the second set of reels that the gaming system employs to determine and display symbols of the second set at the symbol display areas of the designated set is the same as the first set of reels that the gaming system employed to determine and display symbols of the first set at those symbol display areas of the designated set.
In other embodiments, for a particular designated set of the plurality of symbol display areas, the gaming system determines the second set of reels that the gaming system employs to determine and display symbols of the second set at the symbol display areas of the designated set based on the symbols of the first set displayed at the symbol display areas of the designated set of the symbol display areas. For instance, in one example embodiment, for a particular designated set of the symbol display areas, the gaming system determines the second set of reels by, for each column of symbol display areas of that designated set, determining a reel including only the symbols displayed at the symbol display areas of that column. Thus, in this example embodiment, each column of symbol display areas in a particular designated set of the symbol display areas is associated with a reel in the second set of reels that includes only the symbols of the first set originally displayed at the symbol display areas of that particular column.
FIGS. 9A and 9B illustrate screen shots of one such example embodiment of the gaming system of the present disclosure. Specifically, FIG. 9A illustrates a designated set of the symbol display areas including the symbol display areas 910a, 910b, 910c, 910f, 910g, 910h, 910k, 910l, and 910m respectively displaying Seven symbol 920a, Seven symbol 920b, Seven symbol 920c, Bar symbol 920f, Dollar Sign symbol 920g, Double Bar symbol 920h, Seven symbol 920k, Cherry symbol 920l, and Triple Bar symbol 920m. In this example embodiment, as shown in FIG. 9B, the gaming system determines a second set of reels including: (a) a reel 955a that includes the symbols 920a, 920f, and 920k displayed at the symbol display areas 910a, 910f, and 910k and associates the reel 955a with those symbol display areas; (b) a reel 955b that includes the symbols 920b, 920g, and 920l displayed at the symbol display areas 910b, 910g, and 910l and associates the reel 955b with those symbol display areas; and (c) a reel 955c that includes the symbols 920c, 920h, and 920m displayed at the symbol display areas 910c, 910h, and 910m and associates the reel 955c with those symbol display areas.
In another example embodiment, for a particular designated set of the symbol display areas, the gaming system determines the second set of reels by, for each column of symbol display areas of that designated set, creating a reel including only the symbols displayed at the symbol display areas of the designated set. Thus, in this example embodiment, each column of symbol display areas in a particular designated set of the symbol display areas is associated with a reel in the second set of reels that includes only the symbols of the first set originally displayed at the symbol display areas of the designated set.
FIGS. 9A and 9C illustrate screen shots of one such example embodiment of the gaming system of the present disclosure. Specifically, FIG. 9A illustrates a designated set of the symbol display areas including the symbol display areas 910a, 910b, 910c, 910f, 910g, 910h, 910k, 910l, and 910m respectively displaying Seven symbol 920a, Seven symbol 920b, Seven symbol 920c, Bar symbol 920f, Dollar Sign symbol 920g, Double Bar symbol 920h, Seven symbol 920k, Cherry symbol 920l, and Triple Bar symbol 920m. In this example embodiment, as shown in FIG. 9C, the gaming system determines a second set of reels including: (a) a reel 965a that includes the symbols 920a, 920b, 920c, 920f, 920g, 920h, 920k, 920l, and 920m displayed at the symbol display areas of the designated set and associates the reel 965a with the symbol display areas 910a, 910f, and 910k; (b) a reel 965b identical to the reel 965a and associates the reel 965b with the symbol display areas 910b, 910g, and 910l; and (c) a reel 965c that is identical to the reel 965a and associates the reel 965c with the symbol display areas 910c, 910h, and 910m. 
In further embodiments, for a particular designated set of the plurality of symbol display areas, the gaming system determines the second set of reels that the gaming system employs to determine and display symbols of the second set at the symbol display areas of the designated set based on the symbols of the first set displayed at the symbol display areas of the designated set of the symbol display areas and a desired hit frequency and average expected payback percentage. For instance, in one example embodiment, for a particular designated set of the symbol display areas, the gaming system determines the second set of reels by, for each column of symbol display areas of that designated set, determining a reel including the symbols displayed at the symbol display areas of that column and one or more additional symbols such that the hit frequency of that reel approaches the desired hit frequency and the average expected payback percentage approaches the desired average expected payback percentage.
In certain embodiments, for a particular designated set of the symbol display areas, the gaming system replaces the symbols displayed at the symbol display areas of the designated set more than once and provides more than one additional award evaluations. For instance, in one example embodiment, the gaming system determines how many times to replace the symbols displayed at the symbol display areas of the designated set (such as by spinning and stopping a second set of reels in association with the symbol display areas of the designated set) and how many additional award evaluations to provide based on the quantity of displayed triggering symbols. In this example embodiment, each displayed triggering symbol represents one spin of the second set of reels (e.g., if two triggering symbols are displayed, the gaming system spins the reels of the second set twice and provides two additional award determinations).
In various embodiments, instead of (or in addition to) evaluating the symbols displayed at all of the symbol display areas after replacing the symbols of the first set of symbols displayed at the symbol display areas of a designated set of the symbol display areas with symbols of the second set of symbols, the gaming system evaluates only the symbols displayed at the symbol display areas of that designated set. In certain such embodiments, the gaming system does so using a different paytable.
In various embodiments in which the gaming system replaces the symbols of the first set displayed at the symbol display areas of a designated set of the symbol display areas by spinning and stopping a second set of reels in association with the designated set of the symbol display areas, the gaming system employs any suitable spin feature such as, but not limited to: (a) reverse-spinning reels (e.g., spinning bottom-to-top instead of top-to-bottom); (b) locking reels; (c) sideways spinning reels (e.g., left-to-right spin or right-to-left spin); (d) increased spin speed; (e) forward-spinning reels and reverse-spinning reels; and/or (f) additional reel animations (e.g., a sparkle, blur, or wobble effect).
In certain embodiments, after the gaming system replaces the symbols of the first set of symbols displayed at the symbol display areas of the designated set of the symbol display areas with symbols of the second set of symbols, the gaming system repeats the process if another triggering symbol is displayed at one of the symbol display areas of the designated set.
In various embodiments, if the triggering event occurs, the gaming system does not make any award determinations until after the gaming system provides the partial reel re-spin feature.
In certain embodiments, upon an occurrence of the triggering event, the gaming system randomly determines whether to provide a play of a bonus game. In certain such embodiments, if the triggering event occurs, the gaming system displays a plurality of bonus reels and spins and stops the displayed bonus reels. If the symbols displayed on the stopped bonus reels form a bonus triggering combination, the gaming system provides a play of the bonus game. In one such embodiment, the triggering event occurs if a designated symbol or a designated symbol combination is displayed. For instance, in one example embodiment, when the designated symbol is displayed following a spin of the first set of reels, the gaming system zooms in on the designated symbol, displays the plurality of bonus reels, and spins and stops the displayed plurality of bonus reels to determine whether to provide a play of the bonus game.
In certain embodiments, upon an occurrence of the triggering event, the gaming system randomly determines one of a plurality of guaranteed bonus awards to provide the player. In certain such embodiments, if the triggering event occurs, the gaming system displays a plurality of bonus reels and spins and stops the displayed bonus reels. The gaming system provides a guaranteed bonus award associated with the symbols displayed on the stopped bonus reels. In one such embodiment, the triggering event occurs if a designated symbol or a designated symbol combination is displayed. For instance, in one example embodiment, when the designated symbol is displayed following a spin of the first set of reels, the gaming system zooms in on the designated symbol, displays the plurality of bonus reels, and spins and stops the displayed plurality of bonus reels to determine the guaranteed bonus award.

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. 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.
