## Title
Gaming system and method providing a slot game having a surrounded symbol award evaluation

## Abstract

Various embodiments of the present disclosure provide a gaming system and method providing a slot game having a surrounded symbol award evaluation. Generally, in various embodiments, for a play of the slot game having the surrounded symbol award evaluation the gaming system: (a) displays a plurality of symbols at a plurality of symbol display areas; (b) determines whether any displayed non-enclosing symbols are surrounded by a plurality of displayed enclosing symbols; and (c) if so, determines any awards based on the surrounded non-enclosing symbol(s). Thus, instead of (or in addition to) using a payline evaluation, a ways-to-win evaluation, a scatter pay evaluation, or any other evaluation of the displayed symbols to determine whether to provide any awards, the gaming system of the present disclosure does so by determining whether a particular type of symbol (such as an enclosing symbol) surrounds another type of symbol (such as a non-enclosing symbol).

BACKGROUND
Gaming systems (such as electronic gaming machines (EGMs)) 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 gaming system configured to operate a slot or spinning-reel type game, there are a variety of known ways in which the gaming systems may evaluate displayed symbols to determine whether to provide any awards for a play of the slot game. One known manner of doing so includes the gaming system evaluating the displayed symbols to determine whether any winning symbols or winning symbol combinations are displayed along one or more paylines. Another known manner of doing so includes the gaming system determining whether any scatter pay symbols are displayed. Another known manner of doing so includes the gaming system performing a ways-to-win evaluation of the displayed symbols. Each of these award evaluations is described below.
One known gaming system is configured to operate a slot game associated with a plurality of reels and one or more paylines. The slot game may be associated with any suitable number of reels, such as three to five reels, which each include any suitable number of symbols and are configured to display one or more of those symbols at one or more symbol display areas. The gaming system initiates a spin of the reels upon receiving one or more wagers on one or more paylines associated with the slot game. The slot game may be associated with one, three, five, nine, fifteen, twenty-five, or any other suitable number of paylines that are horizontal, vertical, diagonal, or any combination thereof and are associated with one or more of the symbol display areas. One slot game includes a different payline associated with each possible combination of symbol display areas.
The gaming system spins and stops the reels such that a symbol is displayed at each symbol display area. The gaming system analyzes the displayed symbols to determine if the any winning symbols or winning combinations of the symbols are displayed on or along one or more of the wagered-on paylines. The gaming system provides any awards associated with any displayed winning symbols or winning symbol combinations to the player. More specifically, in such slot games, the gaming system generally determines the awards based on the number of wagered-on paylines that pass through each of the winning symbol combinations. That is, the gaming system separately analyzes each wagered-on payline to determine if a winning symbol combination is displayed along that payline. For each occurrence of each payline passing through a winning symbol combination, the gaming system provides the player the award associated with that winning symbol combination. For example, in a five reel slot game, if four related symbols (that form a winning symbol combination) are generated by the first four reels and twelve paylines pass through the first three of those related symbols (i.e., three paylines running left to right pass through all four related symbols and nine paylines running left to right pass through the first three related symbols), the gaming system provides the player twelve awards (i.e., one award for each payline that passes through the winning symbol combination). These twelve separate awards are each for the single occurrence of the winning symbol combination including the four related symbols. Accordingly, the greater the number of wagered-on paylines that pass through a winning symbol combination, the greater the award as compared to an identical winning symbol combination in which fewer wagered-on paylines pass through the same winning symbol combination.
In another type of gaming system configured to operate a slot game (that may or may not be associated with paylines), the gaming system analyzes the displayed symbols to determine if the gaming system has randomly generated and displayed a designated quantity of one or more scatter pay symbols. In this type of scatter pay award evaluation, the location of the designated quantity of displayed scatter pay symbols does not matter as long as those scatter pay symbols are displayed. The gaming system provides any awards associated with any displayed scatter pay symbols to the player.
In another type of gaming system configured to operate a slot game, the gaming system enables the player to wager on a number of ways to win, wherein any award provided to the player is based on the number of associated symbols that are generated in active symbol display areas on a requisite number of adjacent reels. In such ways to win slot games, the gaming system determines any award to provide to the player based on the number of associated symbols that are generated in active symbol display areas on a requisite number of adjacent reels (i.e., not on paylines passing through any displayed winning symbol combinations).
In some known ways to win slot games, the gaming system determines the total number of ways to win by multiplying the number of symbols generated in active symbol display areas on a first reel by the number of symbols generated in active symbol display areas on a second reel by the number of symbols generated in active symbol display areas on a third reel and so on for each reel associated with the slot game with at least one symbol generated in an active symbol display area. For example, a three reel slot game with three symbols generated in active symbol display areas on each reel includes 27 ways to win (i.e., 3 symbols on the first reel×3 symbols on the second reel×3 symbols on the third reel). A four reel slot game with three symbols generated in active symbol display areas on each reel includes 81 ways to win (i.e., 3 symbols on the first reel×3 symbols on the second reel×3 symbols on the third reel×3 symbols on the fourth reel). A five reel slot game with three symbols generated in active symbol display areas on each reel includes 243 ways to win (i.e., 3 symbols on the first reel×3 symbols on the second reel×3 symbols on the third reel×3 symbols on the fourth reel×3 symbols on the fifth reel). Modifying the number of generated symbols by either modifying the number of reels or modifying the number of symbols generated in active symbol display areas by one or more of the reels modifies the number of ways to win.
There is a continuing need to provide new and exciting manners of evaluating symbols to determine awards to increase player enjoyment, entertainment, and excitement.
SUMMARY
Various embodiments of the present disclosure provide a gaming system and method providing a slot game having a surrounded symbol award evaluation. Generally, in various embodiments, for a play of the slot game having the surrounded symbol award evaluation the gaming system: (a) displays a plurality of symbols at a plurality of symbol display areas; (b) determines whether any displayed non-enclosing symbols are surrounded (i.e., enclosed) by a plurality of displayed enclosing symbols; and (c) if so, determines any awards based on the surrounded non-enclosing symbol(s). Thus, instead of (or in addition to) using a payline evaluation, a ways-to-win evaluation, a scatter pay evaluation, or any other evaluation of the displayed symbols to determine whether to provide any awards for the play of the slot game, the gaming system of the present disclosure does so by determining whether a particular type of symbol (such as an enclosing symbol) surrounds another type of symbol (such as a non-enclosing symbol).
More specifically, for a play of the slot game having the surrounded symbol award evaluation in one embodiment, the gaming system provides (such as displays) a plurality of symbol display areas. For each of the symbol display areas, the gaming system displays one of a plurality of different symbols at that symbol display area. The plurality of different symbols include a plurality of enclosing symbols and a plurality of non-enclosing symbols. The gaming system determines whether any displayed non-enclosing symbols are surrounded by a plurality of displayed enclosing symbols. If at least one displayed non-enclosing symbol is surrounded by a plurality of displayed enclosing symbols, the gaming system determines any awards associated with that at least one surrounded non-enclosing symbol and displays any determined awards.
It should thus be appreciated that the gaming system and method of the present disclosure provide a new way to evaluate displayed symbols to determine whether to provide any awards, which increases player 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
Surrounded Symbol Award Evaluation
Various embodiments of the present disclosure provide a gaming system and method providing a slot game having a surrounded symbol award evaluation. Generally, in various embodiments, for a play of the slot game having the surrounded symbol award evaluation the gaming system: (a) displays a plurality of symbols at a plurality of symbol display areas; (b) determines whether any displayed non-enclosing symbols are surrounded (i.e., enclosed) by a plurality of displayed enclosing symbols; and (c) if so, determines any awards based on the surrounded non-enclosing symbol(s). Thus, instead of (or in addition to) using a payline evaluation, a ways-to-win evaluation, a scatter pay evaluation, or any other evaluation of the displayed symbols to determine whether to provide any awards for the play of the slot game, the gaming system of the present disclosure does so by determining whether a particular type of symbol (such as an enclosing symbol) surrounds another type of symbol (such as a non-enclosing symbol).
While the slot game having the surrounded symbol award evaluation of the present disclosure is employed as a primary wagering game in the embodiments described below, it should be appreciated that the slot game may additionally or alternatively be employed as or in association with a bonus game or a secondary game. While any credit balances, any wagers, and any awards are displayed as amounts of monetary currency or credits in the embodiments described below, 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.
Manners in which a Symbol May be Surrounded
In various embodiments, the gaming system determines that a displayed non-enclosing symbol is surrounded by a plurality of displayed enclosing symbols when a continuous or unbroken chain of adjacent symbol display areas that each display an enclosing symbol surrounds the symbol display area of the displayed non-enclosing symbol.
FIG. 1A illustrates a screenshot of an example of one such embodiment. In this example embodiment, the gaming system determines that a displayed non-enclosing Seven symbol 20e is surrounded by a plurality of displayed enclosing X symbols 20a, 20b, 20c, 20f, 20i, 20h, 20g, and 20d because the respective symbol display areas 10a, 10b, 10c, 10f, 10i, 10h, 10g, and 10d of those displayed enclosing X symbols form a continuous chain of adjacent symbol display areas that surround the symbol display area 10e of the displayed non-enclosing Seven symbol 20e. 
In certain embodiments, the gaming system determines that a displayed non-enclosing symbol is surrounded by a plurality of displayed enclosing symbols when: (a) the symbol display area of the displayed non-enclosing symbol is, on all sides, orthogonally adjacent to another symbol display area; and (b) an enclosing symbol is displayed at each such symbol display area orthogonally adjacent to the symbol display area of the displayed non-enclosing symbol. Put differently, in this example embodiment, if the symbol display areas immediately above, below, to the left of, and to the right of a symbol display area of a displayed non-enclosing symbol each display an enclosing symbol, the gaming system determines that those displayed enclosing symbols surround that displayed non-enclosing symbol. If, on the other hand: (a) at least one of the symbol display areas immediately above, below, to the left of, and to the right of a symbol display area of a displayed non-enclosing symbol does not display an enclosing symbol; and/or (b) there is no symbol display area to the left of, and/or to the right of a symbol display area of a displayed non-enclosing symbol, the gaming system determines that that displayed non-enclosing symbol is not surrounded by a plurality of displayed enclosing symbols.
FIG. 1B illustrates a screenshot of an example of one such embodiment. In this example embodiment, the gaming system determines that a displayed non-enclosing Seven symbol 21e is surrounded by a plurality of displayed enclosing X symbols 21b, 21f, 21h, and 21d because: (a) the symbol display area 10e of the displayed non-enclosing Seven symbol 21e is, on all sides, orthogonally adjacent to another symbol display area (i.e., symbol display areas 10b, 10f, 10h, and 10d); and (b) each symbol display area orthogonally adjacent to the symbol display area 10e of the displayed non-enclosing Seven symbol 21e displays an enclosing X symbol.
In various embodiments, the gaming system determines that a displayed non-enclosing symbol is surrounded by a plurality of displayed enclosing symbols when: (a) the symbol display area of the displayed non-enclosing symbol is, on all sides, diagonally adjacent to another symbol display area; and (b) an enclosing symbol is displayed at each such symbol display area diagonally adjacent to the symbol display area of the displayed non-enclosing symbol.
FIG. 1C illustrates a screenshot of an example of one such embodiment. In this example embodiment, the gaming system determines that a displayed non-enclosing Seven symbol 22e is surrounded by a plurality of displayed enclosing X symbols 22a, 22c, 22g, and 22i because: (a) the symbol display area 10e of the displayed non-enclosing Seven symbol 21e is, on all sides, diagonally adjacent to another symbol display area (i.e., symbol display areas 10a, 10c, 10g, and 10i); and (b) each symbol display area diagonally adjacent to the symbol display area 10e of the displayed non-enclosing Seven symbol 21e displays an enclosing X symbol.
In certain embodiments, the gaming system determines that a displayed non-enclosing symbol is surrounded by a plurality of displayed enclosing symbols when, if the symbol display area of the displayed non-enclosing symbol is adjacent to a border of the grid or matrix of symbol display areas, a combination of: (a) a continuous or unbroken chain of adjacent symbol display areas that each display an enclosing symbol, and (b) the border of the symbol display area grid surround the symbol display area of the displayed non-enclosing symbol.
FIG. 1D illustrates a screenshot of an example of one such embodiment. In this example embodiment, the gaming system determines that a displayed non-enclosing Seven symbol 23b is surrounded by a plurality of displayed enclosing X symbols 23a, 23d, 23e, 23f, and 23c and the border of the grid of symbol display areas because: (a) the symbol display area 10b of the displayed non-enclosing Seven symbol 23b is adjacent to the border of the grid of symbol display areas, and (b) the respective symbol display areas 10a, 10d, 10e, 10f, and 10c of those enclosing X symbols form a continuous chain of adjacent symbol display areas that, in combination with the border, surround the symbol display area 10b of the non-enclosing Seven symbol 23b. 
Example Embodiments
FIG. 2 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, for a play of a slot game having the surrounded symbol award evaluation, the gaming system displays a plurality of symbol display areas, as indicated by block 102. For each of the symbol display areas, the gaming system displays one of a plurality of different symbols at that symbol display area, as indicated by block 104. The plurality of different symbols includes a plurality of enclosing symbols and a plurality of non-enclosing symbols. The gaming system determines whether any displayed non-enclosing symbols are surrounded by a plurality of displayed enclosing symbols, as indicated by diamond 106. In this example embodiment, the gaming system determines that a displayed non-enclosing symbol is surrounded by a plurality of displayed enclosing symbols when a continuous or unbroken chain of adjacent symbol display areas that each display an enclosing symbol surrounds the symbol display area of the displayed non-enclosing symbol.
If the gaming system determines that no displayed non-enclosing symbols (if any) are surrounded by a plurality of displayed enclosing symbols, the process 100 proceeds to block 112 and ends. If, on the other hand, the gaming system determines that at least one displayed non-enclosing symbol is surrounded by a plurality of displayed enclosing symbols, the gaming system determines any awards associated with the at least one surrounded non-enclosing symbol, as indicated by block 108. The gaming system displays any determined awards, as indicated by block 110. The process 100 then proceeds to block 112 and ends.
FIGS. 3A, 3B, and 3C illustrate screenshots of different outcomes of plays of one example embodiment of the slot game of the present disclosure implemented as a primary wagering game. In this example embodiment, the gaming system determines that a displayed non-enclosing symbol is surrounded by a plurality of displayed enclosing symbols when a continuous or unbroken chain of adjacent symbol display areas that each display an enclosing symbol surrounds the symbol display area of the displayed non-enclosing symbol.
In this example embodiment, the slot game is associated with a plurality of different symbols including: (a) a plurality of enclosing X symbols; and (b) a plurality of non-enclosing symbols including a non-enclosing Cherry symbol, a non-enclosing Bar symbol, a non-enclosing Triple Cherry symbol, a non-enclosing Double Bar symbol, a non-enclosing Triple Bar symbol, and a non-enclosing Seven symbol. The gaming system displays, such as on a display device 1116 or 1118 (described below), a plurality of symbol display areas including symbol display areas 210a, 210b, 210c, 210d, 210e, 210f, 210g, 210h, 210i, 210j, 210k, 210l, 210m, 210n, and 210o arranged in a 3×5 grid or matrix. Each of the symbol display areas is configured to display one of the symbols.
The gaming system also displays: (a) a message box 260 in which the gaming system displays a variety of messages or indications before, during, or after play of the slot game; and (b) a plurality of meters including: (i) a credit meter 270 in which the gaming system displays the player's credit balance (in credit or currency form), (ii) a wager or bet meter 280 that displays any wager or bet placed on a play of the slot game (in credit or currency form), and (iii) an award meter 290 that displays any awards won for the play of the slot game (in credit or currency form). While in this illustrated example embodiment the gaming system indicates the player's credit balance, any wagers, and any awards in the form of amounts of currency, it should be appreciated that such indications may alternatively or additionally be made in the form of amounts of credits.
Turning to FIG. 3A, the gaming system displays an outcome of a play of the slot game of this example embodiment. In this instance, the gaming system displays: (a) enclosing X symbol 220a at the symbol display area 210a, (b) enclosing X symbol 220b at the symbol display area 210b, (c) enclosing X symbol 220c at the symbol display area 210c, (d) non-enclosing Triple Bar symbol 220d at the symbol display area 210d, (e) enclosing X symbol 220e at the symbol display area 210e, (f) enclosing X symbol 220f at the symbol display area 210f, (g) non-enclosing Seven symbol 220g at the symbol display area 210g, (h) enclosing X symbol 220h at the symbol display area 210h, (i) enclosing X symbol 220i at the symbol display area 210i, (j) enclosing X symbol 220j at the symbol display area 210j, (k) enclosing X symbol 220k at the symbol display area 210k, (l) enclosing X symbol 220l at the symbol display area 210l, (m) enclosing X symbol 220m at the symbol display area 210m, (n) enclosing X symbol 220n at the symbol display area 210n, and (o) enclosing X symbol 220o at the symbol display area 210o. 
The gaming system determines whether any displayed non-enclosing symbols are surrounded by a plurality of displayed enclosing symbols as described above. Here, the gaming system determines that the non-enclosing Seven symbol 220g is surrounded by a plurality of enclosing X symbols 220a, 220b, 220c, 220h, 220m, 220l, 220k, and 220f because the respective symbol display areas 210a, 210b, 210c, 210h, 210m, 210l, 210k, and 210f of those enclosing X symbols form a continuous chain of adjacent symbol display areas that surround the symbol display area 210g of the non-enclosing Seven symbol 220g. 
On the other hand, the gaming system determines that the non-enclosing Triple Bar symbol 220d is not surrounded by a plurality of displayed enclosing X symbols because no continuous chain of adjacent symbol display areas displaying enclosing X symbols surrounds the symbol display area 210d of the non-enclosing Triple Bar symbol 220d. Rather, a plurality of enclosing X symbols 220c, 220h, 220i, 220j, and 220e partially surround the non-enclosing Triple Bar symbol 220d because the respective symbol display areas 210c, 210h, 210i, 210j, and 210e of those enclosing X symbols form a non-continuous chain of adjacent symbol display areas that partially surrounds the symbol display area 210d of the non-enclosing Triple Bar symbol 220d. 
The gaming system determines any awards associated with the surrounded non-enclosing symbols (if any). In this example embodiment, the gaming system determines: (a) an award of 2 credits for each surrounded non-enclosing Cherry symbol, (b) an award of 3 credits for each surrounded non-enclosing Bar symbol, (c) an award of 4 credits for each surrounded non-enclosing Triple Cherry symbol, (d) an award of 6 credits for each surrounded non-enclosing Double Bar symbol, (e) an award of 10 credits for each surrounded non-enclosing Triple Bar symbol, and (f) an award of 20 credits for each surrounded non-enclosing Seven symbol. In other words, in this example embodiment, the gaming system determines the total award for a given play of the slot game by summing the individual award associated with each surrounded non-enclosing symbol. Here, the gaming system determines an award of 20 credits associated with the single surrounded non-enclosing Seven symbol 220g, and displays the determined 20 credit total award in the award meter 290. The gaming system displays the following message in the message box 260: “YOU WIN 20 CREDITS FOR THE SURROUNDED 7!”
Turning to FIG. 3B, the gaming system displays an outcome of another play of the slot game of this example embodiment. In this instance, the gaming system displays: (a) enclosing X symbol 221a at the symbol display area 210a, (b) enclosing X symbol 221b at the symbol display area 210b, (c) enclosing X symbol 221c at the symbol display area 210c, (d) enclosing X symbol 221d at the symbol display area 210d, (e) enclosing X symbol 221e at the symbol display area 210e, (f) enclosing X symbol 221f at the symbol display area 210f, (g) non-enclosing Seven symbol 221g at the symbol display area 210g, (h) enclosing X symbol 221h at the symbol display area 210h, (i) non-enclosing Seven symbol 221i at the symbol display area 210i, (j) enclosing X symbol 221j at the symbol display area 210j, (k) enclosing X symbol 221k at the symbol display area 210k, (l) enclosing X symbol 221l at the symbol display area 210l, (m) enclosing X symbol 221m at the symbol display area 210m, (n) enclosing X symbol 221n at the symbol display area 210n, and (o) enclosing X symbol 2210 at the symbol display area 210o. 
The gaming system determines whether any displayed non-enclosing symbols are surrounded by a plurality of displayed enclosing symbols as described above. Here, the gaming system determines that: (a) the non-enclosing Seven symbol 221g is surrounded by a first plurality of enclosing X symbols 221a, 221b, 221c, 221h, 221m, 221l, 221k, and 221f because the respective symbol display areas 210a, 210b, 210c, 210h, 210m, 210l, 210k, and 210f of those enclosing X symbols form a continuous chain of adjacent symbol display areas that surround the symbol display area 210g of the non-enclosing Seven symbol 221g; and (b) the non-enclosing Seven symbol 221i is surrounded by a second different plurality of enclosing X symbols 221c, 221d, 221e, 221j, 221o, 221n, 221m, and 221h because the respective symbol display areas 210c, 210d, 210e, 210j, 210o, 210n, 210m, and 210h of those enclosing X symbols form a continuous chain of adjacent symbol display areas that surround the symbol display area 210i of the non-enclosing Seven symbol 221i. 
The gaming system determines any awards associated with the surrounded non-enclosing symbols (if any) as described above with respect to FIG. 3A. Here, the gaming system determines an award of 20 credits associated with each of the surrounded non-enclosing Seven symbols 221g and 221i, and displays the determined 40 credit total award in the award meter 290. The gaming system displays the following message in the message box 260: “YOU WIN 20 CREDITS FOR EACH SURROUNDED 7 FOR A TOTAL AWARD OF 40 CREDITS!”
Turning to FIG. 3C, the gaming system displays an outcome of another play of the slot game of this example embodiment. In this instance, the gaming system displays: (a) enclosing X symbol 222a at the symbol display area 210a, (b) enclosing X symbol 222b at the symbol display area 210b, (c) enclosing X symbol 222c at the symbol display area 210c, (d) enclosing X symbol 222d at the symbol display area 210d, (e) enclosing X symbol 222e at the symbol display area 210e, (f) enclosing X symbol 222f at the symbol display area 210f, (g) non-enclosing Seven symbol 222g at the symbol display area 210g, (h) non-enclosing Seven symbol 222h at the symbol display area 210h, (i) non-enclosing Seven symbol 222i at the symbol display area 210i, (j) enclosing X symbol 222j at the symbol display area 210j, (k) enclosing X symbol 222k at the symbol display area 210k, (l) enclosing X symbol 222l at the symbol display area 210l, (m) enclosing X symbol 222m at the symbol display area 210m, (n) enclosing X symbol 222n at the symbol display area 210n, and (o) enclosing X symbol 222o at the symbol display area 210o. 
The gaming system determines whether any displayed non-enclosing symbols are surrounded by a plurality of displayed enclosing symbols as described above. Here, the gaming system determines that the non-enclosing Seven symbols 222g, 222h, and 222i are surrounded by a plurality of enclosing X symbols 222a, 222b, 222c, 222d, 222e, 222j, 222o, 222n, 222m, 222l, 222k, and 222f because the respective symbol display areas 210a, 210b, 210c, 210d, 210e, 210j, 210o, 210n, 210m, 210l, 210k, and 210f of those enclosing X symbols form a continuous chain of adjacent symbol display areas that surround the symbol display areas 210g, 210h, and 210i of the non-enclosing Seven symbols 222g, 222h, and 222i. 
The gaming system determines any awards associated with the surrounded non-enclosing symbols (if any) as described above with respect to FIG. 3A. Here, the gaming system determines an award of 20 credits associated each of the surrounded non-enclosing Seven symbols 222g, 222h, and 222i, and displays the determined 60 credit total award in the award meter 290. The gaming system displays the following message in the message box 260: “YOU WIN 20 CREDITS FOR EACH SURROUNDED 7 FOR A TOTAL AWARD OF 60 CREDITS!”
FIG. 3D illustrates a screenshot of an outcome of a play of another example embodiment of the slot game of the present disclosure implemented as a primary wagering game.

The gaming system determines whether any displayed enclosing symbols of one type are surrounded by a plurality of displayed enclosing symbols of the other type (and vice-versa) as described above. Here, the gaming system determines that: (a) the enclosing A symbol 720p and the enclosing C symbol 720q of the second group are surrounded by a plurality of enclosing symbols 720e, 720f, 720g, 720h, 720r, 720bb, 720aa, 720z, 720y, and 720o of the first group because the respective symbol display areas 710e, 710f, 710g, 710h, 710r, 710bb, 710aa, 710z, 710y, and 710o of those enclosing symbols of the first group form a continuous chain of adjacent symbol display areas that surround the symbol display areas 710p and 710q of the enclosing A symbol 720p and the enclosing C symbol 720q of the second group; (b) the enclosing Y symbol 720v and the enclosing X symbol 720w of the first group are surrounded by a plurality of enclosing symbols 720k, 7201, 720m, 720n, 720x, 720hh, 720gg, 720ff, 720ee, and 720u of the second group because the respective symbol display areas 710k, 710l, 710m, 710n, 710x, 710hh, 710gg, 710ff, 710ee, and 710u of those enclosing symbols of the second group form a continuous chain of adjacent symbol display areas that surround the symbol display areas 710v and 710w of the enclosing Y symbol 720v and the enclosing X symbol 720w of the first group; and (c) the enclosing A symbol 720jj, the enclosing C symbol 720kk, and the enclosing B symbol 720ll of the second group are surrounded by a plurality of enclosing symbols 720y, 720z, 720aa, 720bb, 720cc, 720mm, 720ww, 720vv, 720uu, 720tt, 720ss, and 720ii of the first group because the respective symbol display areas 710y, 710z, 710aa, 710bb, 710cc, 710mm, 710ww, 710vv, 710uu, 710tt, 710ss, and 710ii of those enclosing symbols of the first group form a continuous chain of adjacent symbol display areas that surround the symbol display areas 710jj, 710kk, and 710ll of the enclosing A symbol 720jj, the enclosing C symbol 720kk, and the enclosing B symbol 720ll of the second group.
The gaming system determines any awards associated with the surrounded non-enclosing symbols (if any). In this example embodiment, the gaming system determines: (a) an award of 2 credits for each surrounded enclosing C symbol and for each surrounded Z symbol, (b) an award of 5 credits for each surrounded enclosing B symbol and for each surrounded enclosing Y symbol, and (c) an award of 10 credits for each surrounded enclosing A symbol and for each surrounded enclosing X symbol. Here, the gaming system determines a total award of 44 credits associated with the surrounded enclosing symbols 720p, 720q, 720v, 720w, 720jj, 720kk, and 720ll, and displays the determined 44 credit total award in the award meter 790. The gaming system displays the following message in the message box 760: “YOU WIN 10 CREDITS FOR EACH SURROUNDED X AND EACH SURROUNDED A, 5 CREDITS FOR EACH SURROUNDED Y AND EACH SURROUNDED B, AND 10 CREDITS FOR EACH SURROUNDED C FOR A TOTAL AWARD OF 44 CREDITS!”
In certain embodiments, the plurality of different symbols associated with the slot game include one or more Wild symbols. In various embodiments, the Wild symbol may act as only a non-enclosing symbol, only an enclosing symbol, or either a non-enclosing symbol or an enclosing symbol. In one example embodiment including one set or group of enclosing symbols, when a displayed Wild symbol is surrounded by a plurality of displayed enclosing symbols, the displayed Wild symbol may act as any of the non-enclosing symbols (such as the non-enclosing symbol that would result in the highest award). In another example embodiment including one set or group of enclosing symbols, when a Wild symbol is displayed, the gaming system determines whether that displayed Wild symbol should act as any of the non-enclosing symbols or as an enclosing symbol based on whichever will result in the highest award. In one example embodiment including two sets or group of enclosing symbols of different types, each type of enclosing symbols is associated with its own separate Wild symbol. In another example embodiment including two sets or group of enclosing symbols of different types, the slot game is associated with at least one universal Wild symbol usable with both types of enclosing symbols.
In various embodiments, the plurality of symbols includes one or more Bonus symbols. In one example embodiment in which the Bonus symbols are non-enclosing symbols, when a designated quantity (such as one or three) of displayed Bonus symbols are surrounded by a plurality of enclosing symbols, the gaming system triggers a bonus feature, such as a play of a bonus game. In one embodiment, the triggered bonus feature differs based on how many displayed Bonus symbols are surrounded (e.g., the more displayed Bonus surrounded, the more valuable the Bonus). In certain instances, a plurality of displayed Bonus symbols may be separately surrounded. For example, a first displayed Bonus symbol is surrounded by a first plurality of displayed enclosing symbols and a second different displayed Bonus symbol is surrounded by a second different plurality of displayed enclosing symbols. In these instances, in one embodiment the gaming system combines or aggregates the bonus features associated with both surrounded Bonus symbols and provides the aggregated bonus features. In another embodiment, the gaming system provides an enhanced bonus feature (such as the aggregated bonus features with a modifier).
In another example embodiment in which the Bonus symbols are enclosing symbols, when a plurality of displayed Bonus symbols surround a designated quantity (such as one or three) of displayed non-enclosing symbols, the gaming system triggers the bonus feature. In one embodiment, the triggered bonus feature differs based on how many non-enclosing symbols the displayed Bonus symbols surround (e.g., the more displayed non-enclosing symbols surrounded, the more valuable the Bonus).
As described above, in various embodiments, the plurality of symbols employed for the slot game includes: (a) a plurality of enclosing symbols of a first type, and (b) a plurality of enclosing symbols of a second type. In certain such embodiments, the gaming system provides a special or enhanced award if a displayed enclosing symbol is doubly surrounded. For example, in one such embodiment, the gaming system determines an award if: (a) a displayed enclosing symbol of the first type is surrounded by a plurality of displayed enclosing symbols of the second type, and/or (b) a displayed enclosing symbol of the second type is surrounded by a plurality of displayed enclosing symbols of the first type. In this example embodiment, the gaming system determines a special award if: (a) a displayed enclosing symbol of the first type is surrounded by a plurality of displayed enclosing symbols of the second type and that plurality of displayed enclosing symbols of the second type is surrounded by a plurality of displayed enclosing symbols of the first type, and/or (b) a displayed enclosing symbol of the second type is surrounded by a plurality of displayed enclosing symbols of the first type and that plurality of displayed enclosing symbols of the first type is surrounded by a plurality of displayed enclosing symbols of the second type.
FIG. 9 illustrates a screenshot of an outcome of a play of one such example embodiment of the slot game of the present disclosure implemented as a primary wagering game in which: (a) the slot game is associated with a plurality of different symbols including: (i) a first group or set of a plurality of enclosing X symbols (i.e., enclosing symbols of a first type); and (ii) a second group or set of a plurality of enclosing A symbols (i.e., enclosing symbols of a second type); and (b) the gaming system determines: (i) that a displayed enclosing symbol of the first group is surrounded by a plurality of displayed enclosing symbols of the second group when a continuous or unbroken chain of adjacent symbol display areas that each display an enclosing symbol of the second group surrounds the symbol display area of the displayed enclosing symbol of the first group; and (ii) that a displayed enclosing symbol of the second group is surrounded by a plurality of displayed enclosing symbols of the first group when a continuous or unbroken chain of adjacent symbol display areas that each display an enclosing symbol of the first group surrounds the symbol display area of the displayed enclosing symbol of the second group.
In this example embodiment, the gaming system displays a plurality of symbol display areas including symbol display areas 810a, 810b, 810c, 810d, 810e, 810f, 810g, 810h, 810i, 810j, 810k, 810l, 810m, 810n, 810o, 810p, 810q, 810r, 810s, 810t, 810u, 810v, 810w, 810x, and 810y arranged in a 5×5 grid or matrix. Each of the symbol display areas is configured to display one of the symbols. The gaming system also displays: (a) a message box 860 (described above); and (b) a plurality of meters including: (i) a credit meter 870 (described above), (ii) a wager or bet meter 880 (described above), and (iii) an award meter 890 (described above).
As noted above, the gaming system displays an outcome of a play of the slot game of this example embodiment (not listed for brevity). The gaming system determines whether any displayed enclosing symbols of one type are surrounded by a plurality of displayed enclosing symbols of the other type (and vice-versa) as described above. The gaming system also determines whether any displayed enclosing symbols are doubly surrounded as described above.
Here, the gaming system determines that: (a) the enclosing Seven symbol 820m is surrounded by a plurality of enclosing X symbols 820g, 820h, 820i, 820n, 820s, 820r, 820q, and 820l because the respective symbol display areas 810g, 810h, 810i, 810n, 810s, 810r, 810q, and 810l of those enclosing X symbols of the first group form a continuous chain of adjacent symbol display areas that surround the symbol display area 810p of the enclosing Seven symbol 820m; and (b) the enclosing X symbols 820g, 820h, 820i, 820n, 820s, 820r, 820q, and 820l are surrounded by a plurality of enclosing Seven symbols 820a, 820b, 820c, 820d, 820e, 820j, 820o, 820t, 820y, 820x, 820w, 820v, 820u, 820p, and 820k because the respective symbol display areas 810a, 810b, 810c, 810d, 810e, 810j, 810o, 810t, 810y, 810x, 810w, 810v, 810u, 810p, and 810k of those enclosing Seven symbols form a continuous chain of adjacent symbol display areas that surround the symbol display areas 810g, 810h, 810i, 810n, 810s, 810r, 810q, and 810l of the enclosing X symbols 820g, 820h, 820i, 820n, 820s, 820r, 820q, and 820l. The gaming system determines that the enclosing Seven symbol 820m is doubly surrounded because the enclosing Seven symbol 820m is surrounded by a plurality of displayed enclosing X symbols and that plurality of displayed enclosing X symbols is itself surrounded by a plurality of displayed enclosing Seven symbols.
The gaming system determines any awards associated with the surrounded non-enclosing symbols (if any). In this example embodiment, the gaming system determines: (a) an award of 5 credits for each surrounded enclosing X symbol and for each surrounded Seven symbol, and (b) a special award of 2,000 credits for each doubly-surrounded enclosing X symbol and for each doubly-surrounded enclosing Seven symbol. Here, the gaming system determines a total award of 2,040 credits associated with the surrounded enclosing X symbols and the doubly-surrounded enclosing Seven symbol, and displays the determined 2,040 credit total award in the award meter 890. The gaming system displays the following message in the message box 860: “YOU WIN 5 CREDITS FOR EACH SURROUNDED X AND 2,000 CREDITS FOR THE DOUBLY-SURROUNDED SEVEN!”
FIG. 10 illustrates a screenshot of an outcome of a play of another example embodiment of the slot game of the present disclosure implemented as a primary wagering game. In this example embodiment, the gaming system determines that a displayed non-enclosing symbol is surrounded by a plurality of displayed enclosing symbols when: (a) if the symbol display area of the displayed non-enclosing symbol is not adjacent to a border of the grid or matrix of symbol display areas, a continuous or unbroken chain of adjacent symbol display areas that each display an enclosing symbol surrounds the symbol display area of the displayed non-enclosing symbol; and (b) if the symbol display area of the displayed non-enclosing symbol is adjacent to a border of the grid or matrix of symbol display areas, a combination of: (i) a continuous or unbroken chain of adjacent symbol display areas that each display an enclosing symbol, and (ii) the border of the symbol display area grid surround the symbol display area of the displayed non-enclosing symbol.
In this example embodiment, the slot game is associated with the plurality of different symbols described above with respect to FIG. 3A. In this example embodiment, the gaming system displays a plurality of symbol display areas including symbol display areas 910a, 910b, 910c, 910d, 910e, 910f, 910g, 910h, 910i, 910j, 910k, 9101, 910m, 910n, and 910o arranged in a 3×5 grid or matrix. Each of the symbol display areas is configured to display one of the symbols. The gaming system also displays: (a) a message box 960 (described above); and (b) a plurality of meters including: (i) a credit meter 970 (described above), (ii) a wager or bet meter 980 (described above), and (iii) an award meter 990 (described above).
As noted above, the gaming system displays an outcome of a play of the slot game of this example embodiment. In this instance, the gaming system displays: (a) enclosing X symbol 920a at the symbol display area 910a, (b) enclosing X symbol 920b at the symbol display area 910b, (c) enclosing X symbol 920c at the symbol display area 910c, (d) non-enclosing Seven symbol 920d at the symbol display area 910d, (e) enclosing X symbol 920e at the symbol display area 910e, (f) enclosing X symbol 920f at the symbol display area 910f, (g) non-enclosing Triple Bar symbol 920g at the symbol display area 910g, (h) enclosing X symbol 920h at the symbol display area 910h, (i) enclosing X symbol 920i at the symbol display area 910i, (j) enclosing X symbol 920j at the symbol display area 910j, (k) enclosing X symbol 920k at the symbol display area 910k, (l) enclosing X symbol 920l at the symbol display area 910l, (m) enclosing X symbol 920m at the symbol display area 910m, (n) enclosing X symbol 920n at the symbol display area 910n, and (o) enclosing X symbol 920o at the symbol display area 910o. 
The gaming system determines whether any displayed non-enclosing symbols are surrounded by a plurality of displayed enclosing symbols, as described above. Here, the gaming system determines that: (a) the non-enclosing Seven symbol 920d is surrounded by the combination of a plurality of enclosing X symbols 920e, 920j, 920i, 920h, and 920c and the border of the 3×5 grid because: (i) the symbol display area 910d of the non-enclosing Seven symbol 920d is adjacent to the border; and (ii) the respective symbol display areas 910e, 910j, 910i, 910h, and 910c of those enclosing X symbols form a continuous chain of adjacent symbol display areas that, in combination with the border, surround the symbol display area 910d of the non-enclosing Seven symbol 920d; and (b) the non-enclosing Triple Bar symbol 920g is surrounded by a plurality of enclosing X symbols 920a, 920b, 920c, 920h, 920m, 920l, 920k, and 920f because the respective symbol display areas 910a, 910b, 910c, 910h, 910m, 9101, 910k, and 910f of those enclosing X symbols form a continuous chain of adjacent symbol display areas that surround the symbol display area 910g of the non-enclosing Triple Bar symbol 920g. 
The gaming system determines any awards associated with the surrounded non-enclosing symbols (if any) as described above with respect to FIG. 3A. Here, the gaming system determines an award of 20 credits associated with the surrounded non-enclosing Seven symbol 920d and an award of 10 credits associated with the surrounded non-enclosing Triple Bar symbol 920g, and displays the determined 30 credit total award in the award meter 990. The gaming system displays the following message in the message box 960: “YOU WIN 10 CREDITS FOR THE SURROUNDED TRIPLE BAR AND 20 CREDITS FOR THE SURROUNDED 7 FOR A TOTAL AWARD OF 30 CREDITS!”
Although not shown, it should be appreciated that a non-enclosing symbol may be surrounded by multiple sides of the border and one or more enclosing symbols. For instance, if a non-enclosing symbol was displayed at the symbol display area 910 rather than the enclosing X symbol 920o, the gaming system would determine that that non-enclosing symbol is surrounded by the enclosing X symbols 920j, 920i, and 920n and the border of the 3×5 grid.
In certain such embodiments, for a given surrounded non-enclosing symbol, the gaming system determines the award associated with that surrounded non-enclosing symbol based on whether that non-enclosing symbol is surrounded by enclosing symbols and/or the border. For instance, in one example embodiment, the gaming system determines: (a) a first award if the symbol display area of the surrounded non-enclosing symbol is adjacent to the border of the grid of symbol display areas, and (b) a second different award (such as a higher award) if the symbol display area of the surrounded non-enclosing symbol is not adjacent to the border. In another example embodiment, the gaming system determines larger awards as the number of enclosing symbol surrounding that non-enclosing symbol increases. For instance, the gaming system determines a first award if the non-enclosing symbol is surrounded by the border and three enclosing symbols and a second higher award if the non-enclosing symbol is surrounded by the border and five non-enclosing symbols.
In certain embodiments, at least one of the enclosing symbols (or non-enclosing symbols, or bonus symbols, or wild symbols, or any other suitable symbols) is itself associated with an award, such as an award of credits, an award of a quantity of free plays of the slot game, or a modifier (such as a multiplier). In one embodiment, if the gaming system displays one of the enclosing symbols associated with an award, the gaming system provides that award to the player in addition to any awards associated with any surrounded displayed non-enclosing symbols. In another embodiment, if the gaming system displays one of the enclosing symbols associated with an award, the gaming system provides that award to the player if that displayed enclosing symbol is part of a plurality of displayed enclosing symbols that surround a displayed non-enclosing symbol.
In various embodiments, the slot game is associated with: (a) a plurality of enclosing symbols, (b) a plurality of non-enclosing symbols of a first type, and (b) a plurality of non-enclosing symbols of a second type. In these embodiments, the gaming system determines an award if a plurality of displayed enclosing symbols surround only displayed non-enclosing symbols of the first type or only displayed non-enclosing symbols of the second type. If, on the other hand, a plurality of displayed enclosing symbols surround displayed non-enclosing symbols of both types, the gaming system performs a different function, such as triggers a bonus feature.
In one such example embodiment, the slot game is associated with: (a) a plurality of enclosing symbols, (b) a plurality of non-enclosing hero symbols, and (c) a plurality of non-enclosing monster symbols. In this example embodiment, if a plurality of displayed enclosing symbols surround only displayed non-enclosing hero symbols, the gaming system determines an award based on the surrounded non-enclosing hero symbols. If, on the other hand, a plurality of displayed enclosing symbols surrounds at least one displayed non-enclosing hero symbol and at least one displayed non-enclosing monster symbol, the gaming system triggers a battle bonus feature. In this example embodiment, the quantity of surrounded non-enclosing hero symbols determines how many heroes the gaming system provides the player in the battle bonus feature and the quantity of surrounded non-enclosing monster symbols determines how many monsters the gaming system enables the player to battle in the battle bonus feature. For instance, if a plurality of displayed enclosing symbols surround one displayed non-enclosing hero symbol and three displayed non-enclosing monster symbols, the gaming system provides the player one hero to battle three monsters in the battle bonus feature (either at once or in three separate rounds). In another example, if a plurality of displayed enclosing symbols surround three displayed non-enclosing hero symbols and one displayed non-enclosing monster symbol, the gaming system provides the player three heroes to battle one monster in the battle bonus feature.
In certain embodiments, when a plurality of displayed enclosing symbols surround a plurality of displayed non-enclosing symbols, the gaming system determines the total award by multiplying the award values of any sets of two or more matching surrounded non-enclosing symbols and adding to that value the award values of any single surrounded non-enclosing symbols. In one example, if a plurality of displayed enclosing symbols surround three displayed Cherry non-enclosing symbols, the gaming system determines a total award of 8 credits (i.e., 2 credits×2 credits×2 credits). In another example, if a plurality of displayed enclosing symbols surround one displayed Cherry non-enclosing symbol and one displayed Seven non-enclosing symbol, the gaming system determines a total award of 22 credits (i.e., 2 credits+20 credits). In another example, if a plurality of displayed enclosing symbols surround one displayed Cherry non-enclosing symbol and two displayed Seven non-enclosing symbols, the gaming system determines a total award of 402 credits (i.e., 2 credits+(20 credits×20 credits)).
In various embodiments, the paytable includes award values associated with multiple surrounded matching non-enclosing symbols. For instance, in one example embodiment, the gaming system determines: (a) an award of 2 credits if a single displayed non-enclosing Bar symbol is surrounded by a plurality of displayed enclosing symbols, (b) an award of 10 credits if two displayed non-enclosing Bar symbols are surrounded by a plurality of displayed enclosing symbols, and (c) an award of 100 credits if three displayed non-enclosing Bar symbols are surrounded by a plurality of displayed enclosing symbols.
In certain embodiments, the paytable includes award values associated with multiple surrounded non-matching non-enclosing symbols. For instance, in one example embodiment, the gaming system determines: (a) an award of 500 credits if a displayed non-enclosing Triple Bar symbol, a displayed non-enclosing Double Bar symbol, and a displayed non-enclosing Bar symbol (in that particular order from left to right) are surrounded by a plurality of displayed enclosing symbols; (b) an award of 200 credits if a displayed non-enclosing Bar symbol, a displayed non-enclosing Double Bar symbol, and a displayed non-enclosing Triple Bar symbol (in that particular order from left to right) are surrounded by a plurality of displayed enclosing symbols; and (c) an award of 50 credits if a displayed non-enclosing Double Bar symbol, a displayed non-enclosing Triple Bar symbol, and a displayed non-enclosing Bar symbol (in that particular order from left to right) are surrounded by a plurality of displayed enclosing symbols.
In various embodiments, when at least two different pluralities of displayed enclosing symbols each surround a different set of one or more displayed non-enclosing symbols, the gaming system evaluates each surrounded set separately and sums the awards (if any) for each set to determine the total award. In other embodiments, when at least two different pluralities of displayed enclosing symbols each surround a different set of one or more displayed non-enclosing symbols, the gaming system collectively evaluates the surrounded non-enclosing symbols of each set (i.e., performs one surrounded symbol award evaluation including the surrounded symbols of all sets of surrounded non-enclosing symbols). In another embodiment, the gaming system performs an award evaluation in either of the above-described embodiments and employs a modifier associated with the quantity of sets (e.g., three sets is associated with a 3× multiplier).
It should be appreciated that the surrounded symbol award evaluation described herein may be employed with any suitable type of slot game having any suitable features or characteristics and is not limited to the example embodiments described herein. For example, the surrounded symbol award evaluation may be employed with any of the following slot games: (a) slot games including independent reels, (b) slot games including dependent reels, (c) slot games including a tumbling reels or cascading symbols feature, (d) slot game having a scatter-pay evaluation, (e) slot games having an end-to-end award evaluation, and (f) slot games including split symbols.
It should be appreciated that the surrounded symbol award evaluation described herein may be employed in addition to any other type of award evaluation. For example, the surrounded symbol award evaluation may be employed in addition to a payline evaluation or in addition to a ways-to-win evaluation.
While the above-described example embodiments are directed to gaming systems including video reels, it should be appreciated that gaming systems including mechanical reels may be configured to operate the slot game of the present disclosure having the surrounded symbol award evaluation.

In one example, certain of the game programs are executable by the changeable EGM to operate games having the same or substantially the same game play but different paytables. In different embodiments, each executable game program is associated with a primary game, a secondary game, or both. In certain embodiments, an executable game program is executable by the at least one processor of the at least one changeable EGM as a secondary game to be played simultaneously with a play of a primary game (which may be downloaded to or otherwise stored on the at least one changeable EGM), or vice versa.
In operation of such embodiments, the central server, central controller, or remote host is configured to communicate one or more of the stored executable game programs to the at least one processor of the changeable EGM. In different embodiments, a stored executable game program is communicated or delivered to the at least one processor of the changeable EGM by: (a) embedding the executable game program in a device or a component (such as a microchip to be inserted into the changeable EGM); (b) writing the executable game program onto a disc or other media; or (c) uploading or streaming the executable game program over a data network (such as a dedicated data network). After the executable game program is communicated from the central server, central controller, or remote host to the changeable EGM, the at least one processor of the changeable EGM executes the executable game program to enable the primary game and/or the secondary game associated with that executable game program to be played using the display device(s) and/or the input device(s) of the changeable EGM. That is, when an executable game program is communicated to the at least one processor of the changeable EGM, the at least one processor of the changeable EGM changes the game or the type of game that may be played using the changeable EGM.
In certain embodiments, the gaming system randomly determines any game outcome(s) (such as a win outcome) and/or award(s) (such as a quantity of credits to award for the win outcome) for a play of a primary game and/or a play of a secondary game based on probability data. In certain such embodiments, this random determination is provided through utilization of an RNG, such as a true RNG or a pseudo RNG, or any other suitable randomization process. In one such embodiment, each game outcome or award is associated with a probability, and the gaming system generates the game outcome(s) and/or the award(s) to be provided based on the associated probabilities. In these embodiments, since the gaming system generates game outcomes and/or awards randomly or based on one or more probability calculations, there is no certainty that the gaming system will ever provide any specific game outcome and/or award.
In certain embodiments, the gaming system maintains one or more predetermined pools or sets of predetermined game outcomes and/or awards. In certain such embodiments, upon generation or receipt of a game outcome and/or award request, the gaming system independently selects one of the predetermined game outcomes and/or awards from the one or more pools or sets. The gaming system flags or marks the selected game outcome and/or award as used. Once a game outcome or an award is flagged as used, it is prevented from further selection from its respective pool or set; that is, the gaming system does not select that game outcome or award upon another game outcome and/or award request. The gaming system provides the selected game outcome and/or award. At least U.S. Pat. Nos. 7,470,183; 7,563,163; and 7,833,092 and U.S. Patent Application Publication Nos. 2005/0148382, 2006/0094509, and 2009/0181743 describe various examples of this type of award determination.
In certain embodiments, the gaming system determines a predetermined game outcome and/or award based on the results of a bingo, keno, or lottery game. In certain such embodiments, the gaming system utilizes one or more bingo, keno, or lottery games to determine the predetermined game outcome and/or award provided for a primary game and/or a secondary game. The gaming system is provided or associated with a bingo card. Each bingo card consists of a matrix or array of elements, wherein each element is designated with separate indicia. After a bingo card is provided, the gaming system randomly selects or draws a plurality of the elements. As each element is selected, a determination is made as to whether the selected element is present on the bingo card. If the selected element is present on the bingo card, that selected element on the provided bingo card is marked or flagged. This process of selecting elements and marking any selected elements on the provided bingo cards continues until one or more predetermined patterns are marked on one or more of the provided bingo cards. After one or more predetermined patterns are marked on one or more of the provided bingo cards, game outcome and/or award is determined based, at least in part, on the selected elements on the provided bingo cards. At least U.S. Pat. Nos. 7,753,774; 7,731,581; 7,955,170; and 8,070,579 and U.S. Patent Application Publication No. 2011/0028201 describe various examples of this type of award determination.
In certain embodiments in which the gaming system includes a central server, central controller, or remote host and an EGM, the EGM is configured to communicate with the central server, central controller, or remote host for monitoring purposes only. In such embodiments, the EGM determines the game outcome(s) and/or award(s) to be provided in any of the manners described above, and the central server, central controller, or remote host monitors the activities and events occurring on the EGM. In one such embodiment, the gaming system includes a real-time or online accounting and gaming information system configured to communicate with the central server, central controller, or remote host. In this embodiment, the accounting and gaming information system includes: (a) a player database for storing player profiles, (b) a player tracking module for tracking players (as described below), and (c) a credit system for providing automated transactions. At least U.S. Pat. No. 6,913,534 and U.S. Patent Application Publication No. 2006/0281541 describe various examples of such accounting systems.
As noted above, in various embodiments, the gaming system includes one or more executable game programs executable by at least one processor of the gaming system to provide one or more primary games and one or more secondary games. The primary game(s) and the secondary game(s) may comprise any suitable games and/or wagering games, such as, but not limited to: electro-mechanical or video slot or spinning reel type games; video card games such as video draw poker, multi-hand video draw poker, other video poker games, video blackjack games, and video baccarat games; video keno games; video bingo games; and video selection games.
In certain embodiments in which the primary game is a slot or spinning reel type game, the gaming system includes one or more reels in either an electromechanical form with mechanical rotating reels or in a video form with simulated reels and movement thereof. Each reel displays a plurality of indicia or symbols, such as bells, hearts, fruits, numbers, letters, bars, or other images that typically correspond to a theme associated with the gaming system. In certain such embodiments, the gaming system includes one or more paylines associated with the reels. The example EGM shown in FIG. 12B includes a payline 1152 and a plurality of reels 1154. In certain embodiments, one or more of the reels are independent reels or unisymbol reels. In such embodiments, each independent reel generates and displays one symbol.
In various embodiments, one or more of the paylines is horizontal, vertical, circular, diagonal, angled, or any suitable combination thereof. In other embodiments, each of one or more of the paylines is associated with a plurality of adjacent symbol display areas on a requisite number of adjacent reels. In one such embodiment, one or more paylines are formed between at least two symbol display areas that are adjacent to each other by either sharing a common side or sharing a common corner (i.e., such paylines are connected paylines). The gaming system enables a wager to be placed on one or more of such paylines to activate such paylines. In other embodiments in which one or more paylines are formed between at least two adjacent symbol display areas, the gaming system enables a wager to be placed on a plurality of symbol display areas, which activates those symbol display areas.
In various embodiments, the gaming system provides one or more awards after a spin of the reels when specified types and/or configurations of the indicia or symbols on the reels occur on an active payline or otherwise occur in a winning pattern, occur on the requisite number of adjacent reels, and/or occur in a scatter pay arrangement.
In certain embodiments, the gaming system employs a ways to win award determination. In these embodiments, any outcome to be provided is determined based on a number of associated symbols that are generated in active symbol display areas on the requisite number of adjacent reels (i.e., not on paylines passing through any displayed winning symbol combinations). If a winning symbol combination is generated on the reels, one award for that occurrence of the generated winning symbol combination is provided. At least U.S. Pat. No. 8,012,011 and U.S. Patent Application Publication Nos. 2008/0108408 and 2008/0132320 describe various examples of ways to win award determinations.
In various embodiments, the gaming system includes a progressive award. Typically, a progressive award includes an initial amount and an additional amount funded through a portion of each wager placed to initiate a play of a primary game. When one or more triggering events occurs, the gaming system provides at least a portion of the progressive award. After the gaming system provides the progressive award, an amount of the progressive award is reset to the initial amount and a portion of each subsequent wager is allocated to the next progressive award. At least U.S. Pat. Nos. 5,766,079; 7,585,223; 7,651,392; 7,666,093; 7,780,523; and 7,905,778 and U.S. Patent Application Publication Nos. 2008/0020846, 2009/0123364, 2009/0123363, and 2010/0227677 describe various examples of different progressive gaming systems.
As generally noted above, in addition to providing winning credits or other awards for one or more plays of the primary game(s), in various embodiments the gaming system provides credits or other awards for one or more plays of one or more secondary games. The secondary game typically enables an award to be obtained addition to any award obtained through play of the primary game(s). The secondary game(s) typically produces a higher level of player excitement than the primary game(s) because the secondary game(s) provides a greater expectation of winning than the primary game(s) and is accompanied with more attractive or unusual features than the primary game(s). It should be appreciated that the secondary game(s) may be any type of suitable game, either similar to or completely different from the primary game.
In various embodiments, the gaming system automatically provides or initiates the secondary game upon the occurrence of a triggering event or the satisfaction of a qualifying condition. In other embodiments, the gaming system initiates the secondary game upon the occurrence of the triggering event or the satisfaction of the qualifying condition and upon receipt of an initiation input. In certain embodiments, the triggering event or qualifying condition is a selected outcome in the primary game(s) or a particular arrangement of one or more indicia on a display device for a play of the primary game(s), such as a “BONUS” symbol appearing on three adjacent reels along a payline following a spin of the reels for a play of the primary game. In other embodiments, the triggering event or qualifying condition occurs based on a certain amount of game play (such as number of games, number of credits, amount of time) being exceeded, or based on a specified number of points being earned during game play. It should be appreciated that any suitable triggering event or qualifying condition or any suitable combination of a plurality of different triggering events or qualifying conditions may be employed.
In other embodiments, at least one processor of the gaming system randomly determines when to provide one or more plays of one or more secondary games. In one such embodiment, no apparent reason is provided for the providing of the secondary game. In this embodiment, qualifying for a secondary game is not triggered by the occurrence of an event in any primary game or based specifically on any of the plays of any primary game. That is, qualification is provided without any explanation or, alternatively, with a simple explanation. In another such embodiment, the gaming system determines qualification for a secondary game at least partially based on a game triggered or symbol triggered event, such as at least partially based on play of a primary game.
In various embodiments, after qualification for a secondary game has been determined, the secondary game participation may be enhanced through continued play on the primary game. Thus, in certain embodiments, for each secondary game qualifying event, such as a secondary game symbol, that is obtained, a given number of secondary game wagering points or credits is accumulated in a “secondary game meter” configured to accrue the secondary game wagering credits or entries toward eventual participation in the secondary game. In one such embodiment, the occurrence of multiple such secondary game qualifying events in the primary game results in an arithmetic or exponential increase in the number of secondary game wagering credits awarded. In another such embodiment, any extra secondary game wagering credits may be redeemed during the secondary game to extend play of the secondary game.
In certain embodiments, no separate entry fee or buy-in for the secondary game is required. That is, entry into the secondary game cannot be purchased; rather, in these embodiments entry must be won or earned through play of the primary game, thereby encouraging play of the primary game. In other embodiments, qualification for the secondary game is accomplished through a simple “buy-in.” For example, qualification through other specified activities is unsuccessful, payment of a fee or placement of an additional wager “buys-in” to the secondary game. In certain embodiments, a separate side wager must be placed on the secondary game or a wager of a designated amount must be placed on the primary game to enable qualification for the secondary game. In these embodiments, the secondary game triggering event must occur and the side wager (or designated primary game wager amount) must have been placed for the secondary game to trigger.
In various embodiments in which the gaming system includes a plurality of EGMs, the EGMs are configured to communicate with one another to provide a group gaming environment. In certain such embodiments, the EGMs enable players of those EGMs to work in conjunction with one another, such as by enabling the players to play together as a team or group, to win one or more awards. In other such embodiments, the EGMs enable players of those EGMs to compete against one another for one or more awards. In one such embodiment, the EGMs enable the players of those EGMs to participate in one or more gaming tournaments for one or more awards. At least U.S. Patent Application Publication Nos. 2007/0123341, 2008/0070680, 2008/0176650, and 2009/0124363 describe various examples of different group gaming systems.
In various embodiments, the gaming system includes one or more player tracking systems. Such player tracking systems enable operators of the gaming system (such as casinos or other gaming establishments) to recognize the value of customer loyalty by identifying frequent customers and rewarding them for their patronage. Such a player tracking system is configured to track a player's gaming activity. In one such embodiment, the player tracking system does so through the use of player tracking cards. In this embodiment, a player is issued a player identification card that has an encoded player identification number that uniquely identifies the player. When the player's playing tracking card is inserted into a card reader of the gaming system to begin a gaming session, the card reader reads the player identification number off the player tracking card to identify the player. The gaming system timely tracks any suitable information or data relating to the identified player's gaming session. The gaming system also timely tracks when the player tracking card is removed to conclude play for that gaming session. In another embodiment, rather than requiring insertion of a player tracking card into the card reader, the gaming system utilizes one or more portable devices, such as a cell phone, a radio frequency identification tag, or any other suitable wireless device, to track when a gaming session begins and ends. In another embodiment, the gaming system utilizes any suitable biometric technology or ticket technology to track when a gaming session begins and ends.
In such embodiments, during one or more gaming sessions, the gaming system tracks any suitable information or data, such as any amounts wagered, average wager amounts, and/or the time at which these wagers are placed. In different embodiments, for one or more players, the player tracking system includes the player's account number, the player's card number, the player's first name, the player's surname, the player's preferred name, the player's player tracking ranking, any promotion status associated with the player's player tracking card, the player's address, the player's birthday, the player's anniversary, the player's recent gaming sessions, or any other suitable data. In various embodiments, such tracked information and/or any suitable feature associated with the player tracking system is displayed on a player tracking display. In various embodiments, such tracked information and/or any suitable feature associated with the player tracking system is displayed via one or more service windows that are displayed on the central display device and/or the upper display device. At least U.S. Pat. Nos. 6,722,985; 6,908,387; 7,311,605; 7,611,411; 7,617,151; and 8,057,298 describe various examples of player tracking systems.
It should be understood that various changes and modifications to the present embodiments described herein will be apparent to those skilled in the art. Such changes and modifications can be made without departing from the spirit and scope of the present subject matter and without diminishing its intended advantages. It is therefore intended that such changes and modifications be covered by the appended claims.
