Each of these different enhancement features are described below. Additionally, it should be appreciated that the secondary symbol accumulation enhancement feature for the sequence can be employed to provide other suitable enhancements for the sequence such as but not limited to additional counter resets for the sequence.

In various embodiments, the gaming system and method provide a primary game such as a primary wagering game, and for each play of the primary wagering game the gaming system and method display randomly determined symbols on symbol displays (such as on a plurality of reels) at a plurality of symbol display positions associated with the symbol displays. In various embodiments, one or more plays of the primary wagering game includes one or more of the enhancement features associated with or for triggering an accumulation sequence. For example, the single function or multi-function sequence triggering symbol enhancement feature can be applied for triggering a sequence from the play of the primary wagering game. Upon an occurrence of a symbol accumulation sequence triggering event in or associated with a play of the primary wagering game, the gaming system and method provide the symbol accumulation sequence based on or with one or more of the above enhancement features. In various embodiments, the symbol accumulation sequence triggering event includes the occurrence of a quantity of award symbols on the symbol displays. In various embodiments, the quantity of award symbols is predetermined (such as six award symbols), although the quantity can vary in accordance with the present disclosure. In various embodiments, the award symbols that trigger the symbol accumulation sequence remain on the symbol displays at the respective symbol display positions throughout the symbol accumulation sequence and are thus considered accumulated symbols for the symbol accumulation sequence. In various embodiments, the gaming system and method partly determine the total award for the symbol accumulation sequence based on these accumulated award symbols such as further explained below. The gaming system and method can also modify one or more of these award symbols during the accumulation sequence via various different enhancement features such as further described below. Thus, these the single function or multi-function sequence triggering symbol enhancement feature can provide one or more enhancements for the sequence.

In various embodiments, the symbol accumulation sequence includes a predefined initial quantity of activations of one or a plurality of the symbol displays (such as the reels) that each display a symbol at one of the plurality of symbol display positions associated therewith, wherein each activation utilizes previously one or more of the accumulated award symbols displayed by the symbol displays at the respective symbol display positions. In various embodiments, the predefined initial quantity is three, but can be any suitable quantity.

In various embodiments, the gaming system and method provide one or more of the enhancement features prior to or during the symbol accumulation sequence such as described herein or in other suitable manners. In various embodiments, one or more of the enhancement features are applied to trigger an accumulation sequence and/or to provide an enhancement feature in an accumulation sequence.

In various embodiments, the gaming system and method resets the remaining quantity of activations of the symbol displays for the symbol accumulation sequence responsive to a predefined additional quantity of award symbols being accumulated during an activation of the symbol displays of the symbol accumulation sequence. In various embodiments, the predefined quantity is one, but can be any suitable quantity.

In various embodiments, the gaming system and method ends the symbol accumulation sequence responsive to the quantity of activations of the symbol displays having all been employed (including any additional activations due to any resets of the quantity of remaining activations).

In various embodiments, the gaming system and method ends the symbol accumulation sequence responsive to the award symbols being accumulated at a quantity of (such as all of) the symbol display positions during activations of the symbol displays in the sequence.

While certain embodiments described below are directed to a secondary game including the symbol accumulation sequence, it should be appreciated that such embodiments may additionally or alternatively be employed in association with a primary game such as a primary wagering game.

While the player's credit balance, the player's wager, and any awards are displayed as an amount of monetary credits or currency in certain of the embodiments described below, one or more of such player's credit balance, such player's wager, and any awards provided to such a player may be for non-monetary credits, promotional credits, and/or player tracking points or credits.

FIG. 1 is a flowchart of an example process 100 of operating the gaming system of the present disclosure. In various embodiments, the process is represented by a set of instructions stored in one or more memories and executed by one or more processors. Although the process is described with reference to the flowchart shown in FIG. 1, many other processes of performing the acts associated with this illustrated process may be employed. For example, the order of certain of the illustrated blocks or diamonds may be changed, certain of the illustrated blocks or diamonds may be optional, or certain of the illustrated blocks or diamonds may not be employed.

The gaming system enables a player to place a wager to play a primary wagering game, as indicated in block 102. In various embodiments, the gaming system enables a player to place the wager from a plurality of different wager amounts.

The gaming system displays the play of the primary wagering game, determines whether any winning symbols or winning symbol combinations occur in the play of the primary wagering game, determines any awards based on any of the winning symbols or winning symbol combinations, and displays and provides the player any awards, as indicated in block 104.

The gaming system determines whether a symbol accumulation sequence triggering event occurs in the play of the primary wagering game, as indicated in diamond 106.

Responsive to the gaming system determining that a symbol accumulation sequence triggering event occurs does not occur in the play of the primary wagering game, the gaming system returns to block 102.

Responsive to the gaming system determining that a symbol accumulation sequence triggering event occurs in the play of the primary wagering game, the gaming system initiates the symbol accumulation sequence and initially sets an activation counter associated with the symbol accumulation sequence to an initial quantity of activations of the symbol displays of the symbol accumulation sequence, as indicated in block 108. The activation counter tracks the quantity of activations of the symbol displays (such as the reels) for the symbol accumulation sequence.

For each activation of the symbol displays for the symbol accumulation sequence, the gaming system decreases the activation counter for the symbol accumulation sequence, as indicated in block 110.

For each activation of the symbol displays for the accumulation sequence, the gaming system accumulates any displayed additional award symbols during the symbol accumulation sequence, as indicated in block 112. In various embodiments, the gaming system accumulates award symbols displayed at the symbol display positions not otherwise associated with a previously accumulated award symbol. In other words, the gaming system of these embodiments accumulates up to one award symbol for each symbol display position associated with the symbol displays. If the gaming system determines to accumulate at least one award symbol, for each award symbol accumulated, the gaming system accumulates that award symbol in association with the symbol display position which that award symbol is displayed at. The gaming system displays an indication that an award symbol has been accumulated in association with that symbol display position. In various embodiments, once accumulated in association with a symbol display position for one quantity activations of the symbol accumulation sequence, the gaming system displays one or more award symbols at that same symbol display position for one, a plurality of, or each of the subsequent activations of the symbol displays of the symbol accumulation sequence.

For each activation of the symbol displays for the symbol accumulation sequence where the gaming system accumulates any displayed award symbols, the gaming system resets the counter to the initial quantity of activations for the symbol accumulation sequence, as indicated in block 114.

For each activation of the symbol displays for the symbol accumulation sequence where one of the enhancement features occurs, the gaming system provides and displays that enhancement feature, as indicated in block 116.

For any activation of the symbol displays for the accumulation sequence where an award triggering event occurs, the gaming system determines, displays, and provides the player the respective award, as indicated in block 118.

For a last activation of the symbol displays for the accumulation sequence, the gaming system determines, displays, and provides the player the respective award, as indicated in block 120. In other words, if the counter reaches zero for the symbol accumulation sequence, the gaming system provides any awards based on the accumulated award symbols associated with any of the symbol display positions and terminates the symbol accumulation sequence.

FIGS. 2A to 2Y illustrate screen shots of various points during an example plays of a primary wagering game and a symbol accumulation sequence triggered by one of the plays of the primary wagering game of one example embodiment of the present disclosure.

FIGS. 2A, 2B, 2C, and 2D first illustrate screen shots of various points during example plays of a primary wagering game of one example embodiment of the present disclosure on a gaming system such as an EGM. In this example, the EGM displays via display device 200 (such as a display device of an EGM described below), a plurality of adjacently arranged video reels configured to display a plurality of symbols (on those video reels) that are randomly determined by the processor of the EGM and that are displayed by the EGM at a plurality of symbol display positions respectively associated with the plurality of reels. More specifically, this example embodiment includes: (a) reel 210, reel 220, reel 230, reel 240, and reel 250; and (b) nine respective symbol display positions (not labeled) associated with each of the reels 210, 220, 230, 240, and 250. In this example, each of the reels 210, 220, 230, 240, and 250 includes a plurality of different symbols (not shown) and those different symbols include base symbols and two different types of symbol accumulation sequence triggering symbols including: (1) award symbols; and (2) enhancement feature triggering symbols. FIGS. 2A, 2B, 2C, and 2D show example award symbols 251, 252, 253, and 254; and (2) example enhancement feature triggering symbols 271, 272, 273, and 274. The quantities and positions of such symbols on the reels can vary in accordance with the present disclosure. The symbols on the reels in addition to the symbol accumulation sequence triggering symbols can be any suitable conventional or non-conventional reel symbols. These symbols are sometimes referred to herein as base symbols.

In this example embodiment, the EGM can also cause the display device 200 to display various other information such as but not limited to: (1) a credit meter (not shown) that displays the player's credit balance; (2) a wager display (not shown) that displays any wagers placed on any plays of the primary wagering game; (3) a win display (not shown) that displays any awards won for each play of the primary wagering game (and any plays of secondary games or the symbol accumulation sequence); and (4) a message display (not shown) configured to display messages to the player. The EGM can indicate the player's credit balance, the player's wager, and any awards available to be won or provided to the player in the form of amounts of credits. It should be appreciated that such indications can alternatively or additionally be made in the form of amounts of currency, points, or the like.

For the point of the play of the primary wagering game shown in FIG. 2A, the EGM has received a monetary amount from the player and established a credit balance (not shown) for the player. For the example of FIG. 2A, the EGM has also received a player input for the play of the primary wagering game and an associated wager of credits from the player for that play of the primary wagering game. For the example of FIG. 2A, responsive to this input and this wager (that function as an occurrence of a game triggering event in this example), the EGM has triggered the play of the primary wagering game. For the example of FIG. 2A, for this play of the primary wagering game, the EGM has also: (1) randomly determined a plurality of base symbols (not labeled) of each of the reels 210, 220, 230, 240, and 250 to display at the respective symbol display positions associated with those reels; and (2) caused each of the reels 210, 220, 230, 240, and 250 to spin and to stop spinning to display those randomly determined base symbols at the symbol display positions associated with those reels 210, 220, 230, 240, and 250. FIG. 2A displays the play of the primary wagering game after this has occurred. At this point, the EGM evaluates the symbols displayed at the symbol display positions associated with each of the reels 210, 220, 230, 240, and 250.

In this example, the EGM also displays three symbol accumulation sequence triggering symbols including, in addition to the other displayed base symbols, two award symbols 251 and 252 and one enhancement feature triggering symbol 272 on the reels 210, 220, 230, 240, and 250. In this example, the enhancement feature triggering symbol 272 is a multi-function sequence triggering symbol enhancement feature for the sequence that can function with the award symbols to trigger the symbol accumulation sequence and also functions as a trigger for one of the bonus features as further described below. In this example, since the required quantity of six symbol accumulation sequence triggering symbols needed to trigger the symbol accumulation sequence has not occurred (e.g., only three have occurred), the symbol accumulation sequence has not been triggered from this play of the primary wagering game shown in FIG. 2A. The EGM can display any awards based on the rest of the base symbols on the reels 210, 220, 230, 240, and 250 such as in a conventional manner.

For the point of another play of the primary wagering game shown in FIG. 2B, the EGM has received a player input for that play of the primary wagering game and an associated wager of credits from the player for that play of the primary wagering game. For the example of FIG. 2B, responsive to this input and this wager (that function as an occurrence of a game triggering event in this example), the EGM has triggered this play of the primary wagering game. For the example of FIG. 2B, for this play of the primary wagering game, the EGM has also: (1) randomly determined a plurality of base symbols (not labeled) of each of the reels 210, 220, 230, 240, and 250 to display at the respective symbol display positions associated with those reels; and (2) caused each of the reels 210, 220, 230, 240, and 250 to spin and to stop spinning to display those randomly determined base symbols at the symbol display positions associated with those reels 210, 220, 230, 240, and 250. FIG. 2B displays the play of the primary wagering game after this has occurred. At this point, the EGM evaluates the base symbols displayed at the symbol display positions associated with each of the reels 210, 220, 230, 240, and 250.

In this example, the EGM also displays six symbol accumulation sequence triggering symbols including three award symbols 251, 253, and 254 and three enhancement feature triggering symbols 271, 273, and 274 on the reels 210, 220, 230, 240, and 250. In this example, each of the enhancement feature triggering symbols 271, 273, and 274 is a multi-function sequence triggering symbol enhancement feature for the sequence that functions with the award symbols to trigger the symbol accumulation sequence and also functions as a trigger for one of the bonus enhancement features as further described below. In this example, since the required quantity of six symbol accumulation sequence triggering symbols needed to trigger the symbol accumulation sequence has occurred, the symbol accumulation sequence has been triggered from this play of the primary wagering game. The EGM can display any awards based on the rest of the symbols on the reels such as in a conventional manner.

The enhancement feature triggering symbols 271, 273, and 274 can each be a dedicated enhancement feature triggering symbol or a non-dedicated enhancement feature triggering symbol. A dedicated enhancement feature triggering symbol has a dedicated enhancement feature associated with it. A non-dedicated enhancement feature trigging symbol does not have a single enhancement feature specifically associated with it, but rather has a plurality of different enhancement features associated with it, and when it occurs, the EGM determines (such as randomly or in a predetermined order) which of those different enhancement feature that symbol triggers.

FIG. 2C shows the enhancement feature triggering symbols 271, 273, and 274 being non-dedicated enhancement feature triggering symbols (indicated by no cross-hatching) where the EGM randomly determines the enhancement feature that each non-dedicated enhancement feature will provide. Specifically in this case: (1) the enhancement feature triggering symbol 271 triggers the double-up enhancement feature for the trigger symbol accumulation sequence; (2) the enhancement feature triggering symbol 273 triggers the extra-row enhancement feature for the trigger symbol accumulation sequence; and (3) the enhancement feature triggering symbol 274 triggers the boost enhancement feature for the trigger symbol accumulation sequence.

FIG. 2D shows the enhancement feature triggering symbols 271, 273, and 274 being dedicated enhancement feature triggering symbols (indicated by the cross-hatching that corresponds to the cross-hatching of the optionally displayed enhancement feature indicators 290, 291, and 292) that each provide a dedicated enhancement feature. In this case: (1) the enhancement feature triggering symbol 271 triggers the double-up enhancement feature for the trigger symbol accumulation sequence; (2) the enhancement feature triggering symbol 273 triggers the extra-row enhancement feature for the trigger symbol accumulation sequence; and (3) the enhancement feature triggering symbol 274 triggers the boost enhancement feature for the trigger symbol accumulation sequence. It should be appreciated that the other enhancement features triggerable by the enhancement feature triggering symbols can include, for example, (a) a compression enhancement feature for the trigger symbol accumulation sequence; (b) a jackpot enhancement feature for the trigger symbol accumulation sequence; (c) an extra activation enhancement feature for the trigger symbol accumulation sequence; and (d) a collect enhancement feature for the trigger symbol accumulation sequence.

FIGS. 2E to 2Y illustrate screen shots of various points during the example symbol accumulation sequence triggered from the second play of the primary wagering game as described above. In this example, the EGM displays via display device 200, the plurality of adjacently arranged video reels configured to display award symbols at the plurality of symbol display positions respectively associated with the plurality of reels 210, 220, 230, 240, and 250. For the symbol accumulation sequence, in this example, each of the reels 210, 220, 230, 240, and 250 includes a plurality of different award symbols. In various embodiments, one or more of the reels 210, 220, 230, 240, and 250 can also include one or more additional enhancement feature triggering symbols that can trigger further enhancement features for the symbol accumulation sequence. These reels can be the same or different than the reels in the play of the primary wagering game.

FIG. 2E shows the plurality of reels 210, 220, 230, 240, and 250 for the symbol accumulation sequence before the first activation of the reels 210, 220, 230, 240, and 250 for the symbol accumulation sequence. FIG. 2E shows that the three award symbols 251, 253, and 254 (that along with the enhancement feature triggering symbols 271, 273, and 274 triggered the symbol accumulation sequence) have been accumulated and thus remain at the respective symbol display positions for the symbol accumulation sequence. FIG. 2E shows the enhancement feature triggering symbols 271, 273, and 274 have been removed because they are not award symbols for the symbol accumulation sequence. FIG. 2E shows the initial quantity of activations (labeled “Respins” in this example) are set at 3 for the symbol accumulation sequence. FIG. 2E shows the secondary symbol accumulation enhancement feature for each of the enhancement features triggered by the respective enhancement feature triggering symbols 271, 273, and 274 for the symbol accumulation sequence. Specifically, FIG. 2E shows: (1) a double-up symbol collection area 310 for the symbol accumulation sequence; (2) an extra-row symbol collection area 320 for the symbol accumulation sequence; and (3) a boost symbol collection area 330 for the symbol accumulation sequence. The double-up symbols, the extra-row symbols, and the boost symbols that are collectable in these areas are referred to herein as enhancement symbols. The present disclosure contemplates that other types of enhancement symbols can be employed in accordance with the present disclosure.

FIG. 2E shows that each such symbol collection area is associated with three independent secondary reels that can generate the respective symbols. Specifically, the double-up symbol collection area 310 is associated with three secondary reels 312, 314, and 316, the extra-row symbol collection area 320 is associated with three secondary reels 322, 324, and 326, and the boost symbol collection area 330 is associated with three secondary reels 332, 334, and 336. These secondary reels are only labeled in FIG. 2E in this example.

FIG. 2E shows: (1) the double-up symbol collection area 310 and that no double-up symbols have been accumulated in that collection area; (2) the extra-row symbol collection area 320 and that no extra-row symbols have been accumulated in that collection area; and (3) the boost symbol collection area 330 and that no boost symbols have been accumulated in that collection area. FIG. 2E shows that: (1) the double-up symbol collection area 310 is closest to the reels; (2) the extra-row symbol collection area 320 is next closest to the reels; and (3) the boost symbol collection area 330 is next closest to the reels. FIG. 2E shows that for each of the double-up enhancement feature, the extra-row enhancement feature, and the boost enhancement feature, a quantity (such as three) respective triggering symbols must be collected for the EGM to apply that feature. These quantities can vary and can but do not need to be the same in accordance with the present disclosure.

This configuration can be used to provide either the secondary symbol accumulation enhancement feature with a blocking or delay feature for the sequence, or to provide the secondary symbol accumulation enhancement feature without a blocking or delay feature for the sequence. The secondary symbol accumulation enhancement feature with a blocking or delay feature for the sequence requires the double-up enhancement feature, the extra-row enhancement feature, and the boost enhancement feature to be provided in a specific order. Specifically in this example, the double-up enhancement feature (which has a collection area closest to the reels) must be provided before the extra row enhancement feature and the boost enhancement feature can be provided, and the extra-row enhancement feature (which has a collection area next closest to the reels) must be provided before the boost enhancement feature (which has a collection area furthest from the reels) can be provided. In other words, in this example, the double-up enhancement feature functions as a blocking feature for the extra-row enhancement feature and the boost enhancement feature, and the extra-row enhancement feature functions as a blocking feature for the boost enhancement feature. It should be appreciated that the arrangements and blocking features for two or more enhancements can be provided in any suitable manner in accordance with the present disclosure. Alternatively, the secondary symbol accumulation enhancement feature without a blocking or delay feature for the sequence enables any of the double-up enhancement feature, the extra-row enhancement feature, and the boost enhancement feature to be provided in any order.

FIG. 2F shows the plurality of reels 210, 220, 230, 240, and 250 for the symbol accumulation sequence for a first activation of the reels for the symbol accumulation sequence. FIG. 2F shows the additional award symbol 255 occurred on reel 250 and the EGM accumulates this additional award symbol for the symbol accumulation sequence. FIG. 2F shows the quantity of activations reset to 3 for the symbol accumulation sequence because this additional award symbol has been accumulated in this activation of the reels. FIG. 2F shows that the double-up symbol 313 has occurred on the first secondary reel 312 and has been accumulated in the double-up symbol collection area 310, and the boost symbol 337 has occurred on the third secondary reel 336 and has been accumulated in the boost symbol collection area 330. FIG. 2F thus shows at this point in the symbol accumulation sequence that: (1) one double-up symbol has been accumulated in the double-up symbol collection area 310; (2) zero extra-row symbols have been accumulated in the extra-row symbol collection area 320; and (3) one boost symbol has been accumulated in the boost symbol collection area 330.

FIG. 2G shows the plurality of reels 210, 220, 230, 240, and 250 for the symbol accumulation sequence for a second activation of the reels for the symbol accumulation sequence. FIG. 2G shows no additional award symbols occurred on reels for the symbol accumulation sequence. FIG. 2G shows the quantity of activations as 2 for the symbol accumulation sequence. FIG. 2G shows that the double-up symbol 317 has occurred on the third secondary reel 316 and has been accumulated in the double-up symbol collection area 310. FIG. 2G thus shows at this point in the symbol accumulation sequence that: (1) two double-up symbols have been accumulated in the double-up symbol collection area 310; (2) zero extra-row symbols have been accumulated in the extra-row symbol collection area 320; and (3) one boost symbol has been accumulated in the boost symbol collection area 330.

FIG. 2H shows the plurality of reels 210, 220, 230, 240, and 250 for the symbol accumulation sequence for a third activation of the reels for the symbol accumulation sequence. FIG. 2H shows that the additional award symbol 256 occurred on reel 240 and the EGM accumulates this additional award symbol for the symbol accumulation sequence. FIG. 2H shows the quantity of activations reset to 3 for the symbol accumulation sequence because this additional award symbol has been accumulated in this activation of the reels. FIG. 2H shows that the extra-row symbol 325 has occurred on the second secondary reel 324 and has been accumulated in the extra-row symbol collection area 320. FIG. 2H shows that the boost symbol 335 has occurred on the second secondary reel 334 and has been accumulated in the boost symbol collection area 330. FIG. 2H thus shows at this point in the symbol accumulation sequence that: (1) two double-up symbols have been accumulated in the double-up symbol collection area 310; (2) one extra-row symbol has been accumulated in the extra-row symbol collection area 320; and (3) two boost symbols have been accumulated in the boost symbol collection area 330.

FIG. 2I shows the plurality of reels 210, 220, 230, 240, and 250 for the symbol accumulation sequence for a fourth activation of the reels for the symbol accumulation sequence. FIG. 2I shows that the additional award symbol 257 occurred on reel 240 and the EGM accumulates this additional award symbol for the symbol accumulation sequence. FIG. 2I shows the quantity of activations reset to 3 for the symbol accumulation sequence because this additional award symbol has been accumulated in this activation of the reels.

If a quantity such as three activator symbols (such as example activator symbols 411, 421, and 431) are displayed on the reels 410, 420, and 430 at the symbol display positions associated with the reels 410, 420, and 430, the EGM provides one or more additional features based on the symbol accumulation sequence triggering symbols displayed on the reels 210, 220, 230, 240, and 250 at the respective associated symbol display positions for that play of the primary wagering game.

In one such example embodiment, if there are only one or more award symbols appearing on the reels 210, 220, 230, 240, and 250 and displayed at the symbol display positions associated with those reels 210, 220, 230, 240, and 250 in that play of the primary wagering game (i.e., there are no displayed enhancement feature triggering symbols), the EGM provides the player all of the awards associated with those displayed award symbols.

In one such example embodiment, if there are any enhancement feature triggering symbols appearing on the reels 210, 220, 230, 240, and 250 and displayed at the symbol display positions associated with those reels 210, 220, 230, 240, and 250 in that play of the primary wagering game, the EGM triggers the symbol accumulation sequence, and for each enhancement feature triggering symbol, includes the respective enhancement feature for that symbol accumulation sequence. The EGM uses and accumulates any award symbols displayed on the reels 210, 220, 230, 240, and 250 at any of the symbol display positions in the symbol accumulation sequence.

Thus, in various embodiments, this enhancement feature provides: (1) an additional mechanism to generate awards; (2) an additional mechanism for triggering the symbol accumulation sequence (without requiring the predetermined quantity of symbol accumulation sequence triggering symbols); and (3) an additional way to trigger one or more of the different enhancement features.

For the point of the play of the primary wagering game shown in FIG. 3A, the EGM has received a monetary amount from the player and established a credit balance. For the example of FIG. 3A, the EGM has also received a player input for the play of the primary wagering game and an associated wager of credits from the player for that play of the primary wagering game. For the example of FIG. 3A, responsive to this input and this wager (that function as an occurrence of a game triggering event in this example), the EGM has triggered the play of the primary wagering game. For the example of FIG. 3A, for this play of the primary wagering game, the EGM has also: (1) randomly determined a plurality of symbols (not labeled) of each of the reels 210, 220, 230, 240, and 250 to display at the respective symbol display positions associated with those reels; and (2) caused each of the reels 210, 220, 230, 240, and 250 to spin and to stop spinning to display those randomly determined base symbols at the symbol display positions associated with those reels 210, 220, 230, 240, and 250. For this play of the primary wagering game, the EGM has also: (1) randomly determined any symbols of each of the reels 410, 420, and 430 to display at the respective symbol display positions associated with those reels; and (2) caused each of the reels 410, 420, and 430 to spin and to stop spinning to display those randomly determined symbols at the symbol display positions associated with those reels 410, 420, and 430. FIG. 3A displays the play of the primary wagering game after this has occurred. At this point, the EGM evaluates the symbols displayed at the symbol display positions associated with each of the reels 210, 220, 230, 240, and 250 and on reels 410, 420, and 430.

In this example, EGM displays no symbol accumulation sequence triggering symbols on the reels 210, 220, 230, 240, and 250 and no activator symbols on the reels 410, 420, and 430. In this example, since no activator symbols have occurred at the symbol display positions associated with those reels 410, 420, and 430, the symbol accumulation sequence has not been triggered from this play of the primary wagering game. Thus, the EGM does not provide any accumulation sequence or any enhancement features for this play.

In various embodiments, the EGM can also enable the required quantity (such as of six) symbol accumulation sequence triggering symbols to trigger the symbol accumulation sequence. In this example, since that has also not occurred, the symbol accumulation sequence has not been triggered from this play of the primary wagering game. Thus, the EGM does not provide any accumulation sequence or any enhancement features for this play.

For the point of another play of the primary wagering game shown in FIG. 3B, the EGM has received a player input for the next play of the primary wagering game and an associated wager of credits from the player for that play of the primary wagering game. For the example of FIG. 3B, responsive to this input and this wager (that function as an occurrence of a game triggering event in this example), the EGM has triggered this next play of the primary wagering game. For the example of FIG. 3B, for this play of the primary wagering game, the EGM has also: (1) randomly determined a plurality of symbols (not labeled) of each of the reels 210, 220, 230, 240, and 250 to display at the respective symbol display positions associated with those reels; and (2) caused each of the reels 210, 220, 230, 240, and 250 to spin and to stop spinning to display those randomly determined symbols at the symbol display positions associated with those reels 210, 220, 230, 240, and 250. For this play of the primary wagering game, the EGM has also: (1) randomly determined any symbols of each of the reels 410, 420, and 430 to display at the respective symbol display positions associated with those reels; and (2) caused each of the reels 410, 420, and 430 to spin and to stop spinning to display those randomly determined symbols at the symbol display positions associated with those reels 410, 420, and 430. FIG. 3B displays the play of the primary wagering game after this has occurred. At this point, the EGM evaluates the symbols displayed at the symbol display positions associated with each of the reels 210, 220, 230, 240, and 250 and on reels 410, 420, and 430.

In this example, the EGM displays a plurality of base symbols (not labeled) and two award symbols 251 and 254 on the reels 210, 220, 230, 240, and 250, and one activator symbol on the reels 410, 420, and 430. In this example, since the required quantity of activator symbols needed to trigger the symbol accumulation sequence has not occurred, the symbol accumulation sequence has not been triggered from this play of the primary wagering game. Thus, the EGM does not provide any accumulation sequence or any enhancement features for this play.

For the point of another play of the primary wagering game shown in FIG. 3C, the EGM has received a player input for the next play of the primary wagering game and an associated wager of credits from the player for that play of the primary wagering game. For the example of FIG. 3C, responsive to this input and this wager (that function as an occurrence of a game triggering event in this example), the EGM has triggered this next play of the primary wagering game. For the example of FIG. 3C, for this play of the primary wagering game, the EGM has also: (1) randomly determined a plurality of symbols (not all labeled) of each of the reels 210, 220, 230, 240, and 250 to display at the respective symbol display positions associated with those reels; and (2) caused each of the reels 210, 220, 230, 240, and 250 to spin and to stop spinning to display those randomly determined symbols at the symbol display positions associated with those reels 210, 220, 230, 240, and 250. For this play of the primary wagering game, the EGM has also: (1) randomly determined any symbols of each of the reels 410, 420, and 430 to display at the respective symbol display positions associated with those reels; and (2) caused each of the reels 410, 420, and 430 to spin and to stop spinning to display those randomly determined symbols at the symbol display positions associated with those reels 410, 420, and 430. FIG. 3C displays the play of the primary wagering game after this has occurred. At this point, the EGM evaluates the symbols displayed at the symbol display positions associated with each of the reels 210, 220, 230, 240, and 250 and on reels 410, 420, and 430.

In this example, EGM displays a plurality of base symbols (not labeled) and two award symbol 252 and 253 on the reels 210, 220, 230, 240, and 250, and three activator symbols 411, 421, and 431 on the reels 410, 420, and 430. In this example, since the three activator symbols 411, 421, and 431 have occurred but no enhancement feature triggering symbols have occurred, the symbol accumulation sequence has not been triggered from this play of the primary wagering game. Thus, the EGM does not provide any accumulation sequence. Since the three activator symbols 411, 421, and 431 occurred on the reels 411, 421, and 431, the EGM displays and provides the player an award of 175 credits based on the values displayed on the award symbols 252 and 253. The EGM thus provides this enhancement feature based on the occurrence of the three activator symbols 411, 421, and 431.

For the point of another play of the primary wagering game shown in FIG. 3D, the EGM has received a player input for the next play of the primary wagering game and an associated wager of credits from the player for that play of the primary wagering game. For the example of FIG. 3D, responsive to this input and this wager (that function as an occurrence of a game triggering event in this example), the EGM has triggered this next play of the primary wagering game. For the example of FIG. 3D, for this play of the primary wagering game, the EGM has also: (1) randomly determined a plurality of symbols (not all labeled) of each of the reels 210, 220, 230, 240, and 250 to display at the respective symbol display positions associated with those reels; and (2) caused each of the reels 210, 220, 230, 240, and 250 to spin and to stop spinning to display those randomly determined symbols at the symbol display positions associated with those reels 210, 220, 230, 240, and 250. For this play of the primary wagering game, the EGM has also: (1) randomly determined any symbols of each of the reels 410, 420, and 430 to display at the respective symbol display positions associated with those reels; and (2) caused each of the reels 410, 420, and 430 to spin and to stop spinning to display those randomly determined symbols at the symbol display positions associated with those reels 410, 420, and 430. FIG. 3D displays the play of the primary wagering game after this has occurred. At this point, the EGM evaluates the symbols displayed at the symbol display positions associated with each of the reels 210, 220, 230, 240, and 250 and on reels 410, 420, and 430.

In this example, the EGM displays a plurality of base symbols (not labeled), two award symbol 252 and 253, and three enhancement feature triggering symbols 271, 272, and 273 on the reels 210, 220, 230, 240, and 250, and three activator symbols 411, 421, and 431. In this example, since the three enhancement feature triggering symbols 271, 272, and 273 and the three activator symbols 411, 421, and 431 occurred, the EGM triggers the symbol accumulation sequence from this play of the primary wagering game (even though only two award symbols occurred and even though less than six symbol accumulation sequence triggering symbols occurred). The EGM provides the accumulation sequence with three enhancement features. In this example, each of the enhancement feature triggering symbols 271, 272, and 273 is a multi-function sequence triggering symbol for the sequence that functions as a trigger for one of the bonus features. As with the above described embodiment, the enhancement feature triggering symbols 271, 272, and 273 can each be a dedicated enhancement feature triggering symbol or a non-dedicated enhancement feature triggering symbol. As described above, a dedicated enhancement feature triggering symbol has a dedicated enhancement feature associated with it, and a non-dedicated enhancement feature triggering symbol does not have a single enhancement feature specifically associated with it, but rather has a plurality of different enhancement features associated with it, and when it occurs, the EGM randomly determines which of those different enhancement feature it triggers.

FIG. 3E shows the enhancement feature triggering symbols 271, 272, and 273 being a non-dedicated enhancement feature triggering symbols, and the EGM randomly determines the enhancement feature associated with each such symbol.

In this example, the EGM randomly determines that: (1) the enhancement feature triggering symbol 271 triggers the double-up enhancement feature for the symbol accumulation sequence; (2) the enhancement feature triggering symbol 272 triggers the extra-row enhancement feature for the symbol accumulation sequence; and (3) the enhancement feature triggering symbol 273 triggers the boost enhancement feature for the symbol accumulation sequence (indicated by the cross-hatching that corresponds to the cross-hatching of the optionally displayed enhancement feature indicators 290, 291, and 292). It should be appreciated that the other enhancement features triggerable by the enhancement feature triggering symbols can include, for example: (a) a compression enhancement feature for the trigger symbol accumulation sequence; (b) a jackpot enhancement feature for the trigger symbol accumulation sequence; (c) an extra activation enhancement feature for the trigger symbol accumulation sequence; and (d) a collect enhancement feature for the trigger symbol accumulation sequence.

FIGS. 3F to 3Z illustrate screen shots of various points during the example symbol accumulation sequence triggered from the third play of the primary wagering game as described above. In this example, the EGM displays via display device 200, the plurality of adjacently arranged video reels configured to display award symbols at the plurality of symbol display positions respectively associated with the plurality of reels 210, 220, 230, 240, and 250. For the symbol accumulation sequence, in this example, each of the reels includes a plurality of different award symbols. In various embodiments, one or more of the reels can also include one or more additional enhancement feature triggering symbols that can trigger further enhancement features for the symbol accumulation sequence.

FIG. 3F shows the plurality of reels 210, 220, 230, 240, and 250 for the symbol accumulation sequence before the first activation of the reels 210, 220, 230, 240, and 250 for the symbol accumulation sequence. FIG. 3F shows that the two award symbols 252 and 253 have been accumulated and thus remain at the respective symbol display positions for the symbol accumulation sequence. FIG. 3F shows the enhancement feature triggering symbols 271, 272, and 273 have been removed because they are not award symbols for the symbol accumulation sequence. FIG. 3F shows the initial quantity of activations (labeled “Respins” in this example) are set at 3 for the symbol accumulation sequence. FIG. 3F shows the secondary symbol accumulation enhancement feature for each of the enhancement features randomly determined based on the enhancement feature triggering symbols 271, 272, and 273 for the symbol accumulation sequence. Specifically, FIG. 3F shows: (1) a double-up symbol collection area 310 for the symbol accumulation sequence; (2) an extra-row symbol collection area 320 for the symbol accumulation sequence; and (3) a boost symbol collection area 330 for the symbol accumulation sequence. FIG. 3F also shows that each such symbol collection area is associated with three independent secondary reels that can generate the respective symbols. Specifically, the double-up symbol collection area 310 is associated with three secondary reels 312, 314, and 316, the extra-row symbol collection area 320 is associated with three secondary reels 322, 324, and 326, and the boost symbol collection area 330 is associated with three secondary reels 332, 334, and 336 (which are only labeled in FIG. 3F in this example). FIG. 3F shows: (1) the double-up symbol collection area 310 and that no double-up symbols have been accumulated in that collection area 310; (2) the extra-row symbol collection area 320 and that no extra-row symbols have been accumulated in that collection area 320; and (3) the boost symbol collection area 330 and that no boost symbols have been accumulated in that collection area 330. FIG. 3F shows that: (1) the double-up symbol collection area 310 is closest to the reels 210, 220, 230, 240, and 250; (2) the extra-row symbol collection area 320 is next closest to the reels 210, 220, 230, 240, and 250; and (3) the boost symbol collection area 330 is next closest to the reels 210, 220, 230, 240, and 250. FIG. 3F shows that for each of the double-up enhancement feature, the extra-row enhancement feature, and the boost enhancement feature, a quantity (such as three) respective triggering symbols must be collected for the EGM to apply that enhancement feature. These quantities can vary and can but do not need to be the same in accordance with the present disclosure.

FIG. 3G shows the plurality of reels 210, 220, 230, 240, and 250 for the symbol accumulation sequence for a first activation of the reels for the symbol accumulation sequence. FIG. 3G shows the additional award symbols 251 and 254 occurred on reels 210 and 250 and the EGM accumulates these additional award symbols for the symbol accumulation sequence. FIG. 3G shows the quantity of activations reset to 3 for the symbol accumulation sequence because these additional award symbols have been accumulated in this activation of the reels. FIG. 3G shows that the double-up symbol 313 has occurred on the secondary reel 312 and has been accumulated in the double-up symbol collection area 310, and the boost symbol 337 has occurred on the secondary reel 336 and been accumulated in the boost symbol collection area 330. FIG. 3G thus shows at this point in the symbol accumulation sequence that: (1) one double-up symbol has been accumulated in the double-up symbol collection area 310; (2) zero extra-row symbols have been accumulated in the extra-row symbol collection area 320; and (3) one boost symbol has been accumulated in the boost symbol collection area 330.

FIG. 3H shows the plurality of reels 210, 220, 230, 240, and 250 for the symbol accumulation sequence for a second activation of the reels for the symbol accumulation sequence.

FIG. 3I shows that the additional award symbol 255 occurred on reel 240 and the EGM accumulates this additional award symbol for the symbol accumulation sequence. FIG. 3I shows the quantity of activations reset to 3 for the symbol accumulation sequence because this additional award symbol has been accumulated in this activation of the reels. FIG. 3I shows that the extra-row symbol 325 has occurred on the secondary reel 324 and has been accumulated in the extra-row symbol collection area 320. FIG. 3I shows that the boost symbol 335 has occurred on the secondary reel 334 and has been accumulated in the boost symbol collection area 330. FIG. 3I thus shows at this point in the symbol accumulation sequence that: (1) two double-up symbols have been accumulated in the double-up symbol collection area 310; (2) one extra-row symbol has been accumulated in the extra-row symbol collection area 320; and (3) two boost symbols have been accumulated in the boost symbol collection area 330.

FIG. 3J shows the plurality of reels 210, 220, 230, 240, and 250 for the symbol accumulation sequence for a fourth activation of the reels for the symbol accumulation sequence. FIG. 3J shows that the additional award symbol 256 occurred on reel 240 and the EGM accumulates this additional award symbol for the symbol accumulation sequence. FIG. 3J shows the quantity of activations reset to 3 for the symbol accumulation sequence because this additional award symbol has been accumulated in this activation of the reels. FIG. 3J shows that the double-up symbol 315 has occurred on the secondary reel 314 and has been accumulated in the double-up symbol collection area 310. FIG. 3J thus shows at this point in the symbol accumulation sequence that: (1) three double-up symbols have been accumulated in the double-up symbol collection area 310; (2) one extra-row symbol has been accumulated in the extra-row symbol collection area 320; and (3) two boost symbols have been accumulated in the boost symbol collection area 330.

FIGS. 3K and 3L shows that since three double-up symbols have been accumulated in the double-up symbol collection area 310, the EGM now applies this double-up enhancement feature to the award symbols accumulated on the reels in the symbol accumulation sequence. Specifically, the EGM doubles the values of all of the award symbols accumulated on the reels in the symbol accumulation sequence. FIG. 3L also shows that since three double-up symbols have been accumulated in the double-up symbol collection area 310, the EGM now adds a new double-up symbol collection area 310A in the symbol accumulation sequence. FIG. 3K also shows that the extra-row symbol collection area 320 and the boost symbol collection area 330 have both moved downwardly toward the reels.

FIG. 3M shows the plurality of reels 210, 220, 230, 240, and 250 for the symbol accumulation sequence for a fifth activation of the reels for the symbol accumulation sequence. FIG. 3M shows no additional award symbols occurred on reels for the symbol accumulation sequence. FIG. 3M shows the quantity of activations as 2 for the symbol accumulation sequence. FIG. 3M shows that the boost symbol 333 has occurred on the secondary reel 332 of the boost symbol collection area and has been accumulated in the boost symbol collection area 330. FIG. 3M thus shows at this point in the symbol accumulation sequence that: (1) one extra-row symbol has been accumulated in the extra-row symbol collection area 320; (2) two boost symbols have been accumulated in the boost symbol collection area 330; and (3) zero double-up symbols have been accumulated in the double-up symbol collection area 310A.

FIG. 3N shows that even though three double-up symbols have been accumulated in the boost symbol collection area 320, the EGM does not yet and cannot apply this boost enhancement feature to the award symbols accumulated on the reels in the symbol accumulation sequence because the boost enhancement feature is blocked by the uncompleted extra-row symbol collection area 320.

FIG. 3O shows the plurality of reels 210, 220, 230, 240, and 250 for the symbol accumulation sequence for a sixth activation of the reels for the symbol accumulation sequence.

FIG. 3O shows that the extra-row symbol 327 has occurred on the secondary reel 326 and has been accumulated in the extra-row symbol collection area 320. FIG. 3O also shows that the double-up symbol 313 has occurred on the secondary reel 332 and has been accumulated in the double-up symbol collection area 310A. FIG. 3O thus shows at this point in the symbol accumulation sequence that: (1) two extra-row symbols have been accumulated in the extra-row symbol collection area 320; (2) three boost symbols have been accumulated in the boost symbol collection area 330 and the boost enhancement is ready to apply but is blocked by the extra-row symbol collection area; and (3) one double-up symbol has been accumulated in the new double-up symbol collection area 310A.

FIG. 3P shows the plurality of reels 210, 220, 230, 240, and 250 for the symbol accumulation sequence for a seventh activation of the reels for the symbol accumulation sequence. FIG. 3P shows that two additional award symbol 257 and 258 occurred on reels for the symbol accumulation sequence. FIG. 3P shows the quantity of activations reset to 3 for the symbol accumulation sequence because these additional award symbols have been accumulated in this activation of the reels. FIG. 3P shows that the extra-row symbol 323 has occurred on the first secondary reel 322 and has been accumulated in the extra-row symbol collection area 320. FIG. 3P also shows that the double-up symbol 315 has occurred on the secondary reel 314 and has been accumulated in the double-up symbol collection area 310A. FIG. 3P thus shows at this point in the symbol accumulation sequence that: (1) three extra-row symbols have been accumulated in the extra-row symbol collection area 320 and the extra-row enhancement is ready to apply; (2) three boost symbols have been accumulated in the boost symbol collection area 320 and the boost enhancement is ready to apply; and (3) two double-up symbols have been accumulated in the double-up symbol collection area 310A.

FIGS. 3Q and 3R show that since three extra-row symbols have been accumulated in the extra-row symbol collection area 320, the EGM now applies this extra-row enhancement feature to the reels in the symbol accumulation sequence. FIG. 3R shows this extra row 290. FIGS. 3Q and 3R shows that since three boost symbols have been accumulated in the boost symbol collection area 330 that is no longer at this point blocked by the extra-row symbol collection area 320, the EGM now applies this boost enhancement feature to the accumulated award symbols in the symbol accumulation sequence. Specifically, the EGM adds a randomly determined amount to each of the values of all of the award symbols accumulated on the reels in the symbol accumulation sequence as best shown in FIG. 3S. In this example, a plurality of the added amounts are different, although two or more of the added values can be the same in accordance with the present disclosure. FIGS. 3R and 3S show that since three extra-row symbols have been accumulated in the extra-row symbol collection area 320, the EGM now adds a new extra-row symbol collection area 320A in the symbol accumulation sequence. FIG. 3S also shows that since three boost symbols have been accumulated in the boost symbol collection area 330, the EGM now adds a new boost symbol collection area 330A in the symbol accumulation sequence.

FIG. 3T shows that the boost symbol 335 has occurred on the secondary reel 334 and has been accumulated in the boost symbol collection area 330A. FIG. 3T thus shows at this point in the symbol accumulation sequence that: (1) two double-up symbols have been accumulated in the double-up symbol collection area 310A; (2) zero extra-row symbols have been accumulated in the extra-row symbol collection area 320A; and (3) one boost symbol has been accumulated in the boost symbol collection area 330A.

FIG. 3U shows the plurality of reels 210, 220, 230, 240, and 250 for the symbol accumulation sequence for a ninth activation of the reels for the symbol accumulation sequence. FIG. 3U shows two additional award symbols 259 and 260 occurred on reels for the symbol accumulation sequence. Specifically, these two award symbols have occurred and been accumulated in the extra row 290. FIG. 3U shows the quantity of activations reset to 3 for the symbol accumulation sequence because these additional award symbols have been accumulated in this activation of the reels. FIG. 3U shows that no additional boost, double-up, or extra-row symbols have occurred in this activation. FIG. 3U thus shows at this point in the symbol accumulation sequence that: (1) two double-up symbols have been accumulated in the double-up symbol collection area 310A; (2) zero extra-row symbols have been accumulated in the new extra-row symbol collection area 320A; and (3) one boost symbol has been accumulated in the boost symbol collection area 330A.

FIG. 3W shows the plurality of reels 210, 220, 230, 240, and 250 for the symbol accumulation sequence for an eleventh activation of the reels for the symbol accumulation sequence. FIG. 3W shows no additional award symbols occurred on reels for the symbol accumulation sequence. FIG. 3W shows the quantity of activations as 1 for the symbol accumulation sequence. FIG. 3W shows that one additional double-up symbol 317 have occurred in this activation. FIG. 3W shows that one extra-row symbol 323 has occurred in this activation. FIG. 3W thus shows at this point in the symbol accumulation sequence that: (1) three double-up symbols have been accumulated in the double-up symbol collection area 310A and that this enhancement feature is ready to apply to the accumulated award symbols; (2) one extra-row symbol has been accumulated in the extra-row symbol collection area 320A; and (3) one boost symbol has been accumulated in the boost symbol collection area 330A.

FIGS. 3X and 3Y show that since three double-up symbols have been accumulated in the double-up symbol collection area 310A, the EGM now applies this double-up enhancement feature (again) to the award symbols accumulated on the reels in the symbol accumulation sequence. Specifically, the EGM doubles the values of all of the award symbols accumulated on the reels in the symbol accumulation sequence. FIG. 3Y also shows that since three double-up symbols have been accumulated in the double-up symbol collection area 310A, the EGM now adds a new double-up symbol collection area 310B in the symbol accumulation sequence. FIG. 3Y also shows that the extra-row symbol collection area 320A and the boost symbol collection area 330A have both moved downwardly toward the reels.

FIG. 3Z shows the plurality of reels 210, 220, 230, 240, and 250 for the symbol accumulation sequence for a twelfth activation of the reels for the symbol accumulation sequence. FIG. 3Z shows no additional award symbols occurred on reels for the symbol accumulation sequence. FIG. 3Z shows an indication that the quantity of activations is 0 for the symbol accumulation sequence and thus there are no remaining activations of the reels for the symbol accumulation sequence. FIG. 3Z shows that no additional boost, double-up, or extra-row symbols have occurred in this activation. FIG. 3Z thus shows at this point in the symbol accumulation sequence that: (1) one extra-row symbol has been accumulated in the extra-row symbol collection area 320A; (2) one boost symbol has been accumulated in the boost symbol collection area 330A; and (3) no double-up symbols have been accumulated in the double-up symbol collection area 310B. FIG. 3Z shows that the total award as 4700 credits which is the sum values of the accumulated award symbols.

FIG. 3AA shows an alternative embodiment where after an enhancement feature is used one or more times, it does not reappear. In this example, the double-up symbol collection area 310B does not reappear after it is used the second time.

FIG. 3BB shows an alternative embodiment including alternative enhancement features and specifically alternative collection areas such as compress collection area 350 and jackpots collection area 360. The compress collection area 350 is associated with a compression enhancement feature and the jackpots collection area 360 is associated with a jackpot enhancement feature.

FIGS. 3CC, 3DD, and 3EE show for this alternative embodiment of FIG. 3BB that that since three compress symbols (not labeled) have been accumulated in the compress symbol collection area 350, the EGM applies the compress enhancement feature to the award symbols accumulated on the reels in the symbol accumulation sequence. Specifically, for each column, the EGM adds all the values of all of the award symbols accumulated on the reels in that column and displays a new award symbol at the bottommost symbol display position. The EGM displays the new award symbol indicating the sum of such values (or at least the sum of such values). The EGM also removes each of the other award symbols in each of the columns. In this example, (1) for the first column of symbol display positions, the EGM uses the values 200 and 75 respectively associated with the accumulated award symbols 271 and 272 to determine the value of 275 associated with the displayed new award symbol 281 (and removes the award symbols 271 and 272 from the display); (2) for the second column of symbol display positions, the EGM uses the values 100 and 200 respectively associated with the accumulated award symbols 273 and 274 to determine the value of 300 associated with the displayed new award symbol 282 (and removes the award symbols 273 and 274 from the display); (3) for the third column of symbol display positions, the EGM uses the values 75 and 50 respectively associated with the accumulated award symbols 275 and 276 to determine the value of 125 associated with the displayed new award symbol 283 (and removes the award symbols 275 and 276 from the display); (4) for the fourth column of symbol display positions, the EGM uses the values 100 and 100 respectively associated with the accumulated award symbols 277 and 278 to determine the value of 200 associated with the displayed new award symbol 284 (and removes the award symbols 277 and 278 from the display); and (5) for the fifth column of symbol display positions, the EGM uses the values 100 and 200 respectively associated with the accumulated award symbols 279 and 280 to determine the value of 300 associated with the displayed new award symbol 285 (and removes the award symbols 279 and 280 from the display). The EGM also removes the jackpot symbol collection area 360 for the rest of the sequence in this example embodiment (as shown in FIG. 3FF). In various embodiments, the EGM can apply this compression feature on less than all of the columns. In various other embodiments, the EGM can apply this compression feature to one or more of the rows of the symbol display positions. In various other embodiments, the EGM can apply this compression feature to one or more of the columns and to one or more of the rows of the symbol display positions. In various other embodiments, the EGM displays the multiple award symbols compressing into the single award symbol in any suitable manner.

Although not shown, the EGM can provide a collect symbol collection area that is associated with a collect enhancement feature that can apply to the award symbols accumulated on the reels in the symbol accumulation sequence. For the collect enhancement feature, the EGM adds all the values of all of the award symbols accumulated on all of the reels and displays and provides that total value to the player without changing any of the award symbols at the symbol display positions. The EGM thus continues to display the award symbol in each of the rows and columns. In various other embodiments, the EGM can apply this collect feature to less than all of the rows and/or columns.

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 in which 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 before delivery to a gaming establishment or before being provided to a player; and (b) a changeable EGM in which computerized game programs executable by the EGM for controlling any primary games and/or secondary games displayed by the EGM are downloadable or otherwise transferred to the EGM through a data network or remote communication link; from a USB drive, flash memory card, or other suitable memory device; or in any other suitable manner 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. Examples of this type of award evaluation are described in U.S. Pat. No. 7,470,183, entitled “Finite Pool Gaming Method and Apparatus”; U.S. Pat. No. 7,563,163, entitled “Gaming Device Including Outcome Pools for Providing Game Outcomes”; U.S. Pat. No. 7,833,092, entitled “Method and System for Compensating for Player Choice in a Game of Chance”; U.S. Pat. No. 8,070,579, entitled “Bingo System with Downloadable Common Patterns”; and U.S. Pat. No. 8,398,472, entitled “Central Determination Poker Game,” which are incorporated herein by reference.

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. Examples of this type of award determination are described in U.S. Pat. No. 7,753,774, entitled “Using Multiple Bingo Cards to Represent Multiple Slot Paylines and Other Class III Game Options”; U.S. Pat. No. 7,731,581, entitled “Multi-Player Bingo Game with Multiple Alternative Outcome Displays”; U.S. Pat. No. 7,955,170, entitled “Providing Non-Bingo Outcomes for a Bingo Game”; U.S. Pat. No. 8,070,579, entitled “Bingo System with Downloadable Common Patterns”; and U.S. Pat. No. 8,500,538, entitled “Bingo Gaming System and Method for Providing Multiple Outcomes from Single Bingo Pattern,” which are incorporated herein by reference.

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 configured to store player profiles, (b) a player tracking module configured to track players (as described below), and (c) a credit system configured to provide automated transactions. Examples of such accounting systems are described in U.S. Pat. No. 6,913,534, entitled “Gaming Machine Having a Lottery Game and Capability for Integration with Gaming Device Accounting System and Player Tracking System,” and U.S. Pat. No. 8,597,116, entitled “Virtual Player Tracking and Related Services,” which are incorporated herein by reference.

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 2000b shown in FIG. 5B 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. Examples of ways to win award determinations are described in U.S. Pat. No. 8,012,011, entitled “Gaming Device and Method Having Independent Reels and Multiple Ways of Winning”; U.S. Pat. No. 8,241,104, entitled “Gaming Device and Method Having Designated Rules for Determining Ways To Win”; and U.S. Pat. No. 8,430,739, entitled “Gaming System and Method Having Wager Dependent Different Symbol Evaluations,” which are incorporated herein by reference.

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. Examples of progressive gaming systems are described in U.S. Pat. No. 7,585,223, entitled “Server Based Gaming System Having Multiple Progressive Awards”; U.S. Pat. No. 7,651,392, entitled “Gaming Device System Having Partial Progressive Payout”; U.S. Pat. No. 7,666,093, entitled “Gaming Method and Device Involving Progressive Wagers”; U.S. Pat. No. 7,780,523, entitled “Server Based Gaming System Having Multiple Progressive Awards”; and U.S. Pat. No. 8,337,298, entitled “Gaming Device Having Multiple Different Types of Progressive Awards,” which are incorporated herein by reference.

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). 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. 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 providing 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. Examples of group gaming systems are described in U.S. Pat. No. 8,070,583, entitled “Server Based Gaming System and Method for Selectively Providing One or More Different Tournaments”; U.S. Pat. No. 8,500,548, entitled “Gaming System and Method for Providing Team Progressive Awards”; and U.S. Pat. No. 8,562,423, entitled “Method and Apparatus for Rewarding Multiple Game Players for a Single Win,” which are incorporated herein by reference.

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 mobile 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. Examples of player tracking systems are described in U.S. Pat. No. 6,722,985, entitled “Universal Player Tracking System”; U.S. Pat. No. 6,908,387, entitled “Player Tracking Communication Mechanisms in a Gaming Machine”; U.S. Pat. No. 7,311,605, entitled “Player Tracking Assembly for Complete Patron Tracking for Both Gaming and Non-Gaming Casino Activity”; U.S. Pat. No. 7,611,411, entitled “Player Tracking Instruments Having Multiple Communication Modes”; U.S. Pat. No. 7,617,151, entitled “Alternative Player Tracking Techniques”; and U.S. Pat. No. 8,057,298, entitled “Virtual Player Tracking and Related Services,” which are incorporated herein by reference.

Web-Based Gaming

In various embodiments, the gaming system includes one or more servers configured to communicate with a personal gaming device—such as a smartphone, a tablet computer, a desktop computer, or a laptop computer—to enable web-based game play using the personal gaming device. In various embodiments, the player must first access a gaming website via an Internet browser of the personal gaming device or execute an application (commonly called an “app”) installed on the personal gaming device before the player can use the personal gaming device to participate in web-based game play. In certain embodiments, the one or more servers and the personal gaming device operate in a thin-client environment. In these embodiments, the personal gaming device receives inputs via one or more input devices (such as a touch screen and/or physical buttons), the personal gaming device sends the received inputs to the one or more servers, the one or more servers make various determinations based on the inputs and determine content to be displayed (such as a randomly determined game outcome and corresponding award), the one or more servers send the content to the personal gaming device, and the personal gaming device displays the content.

In certain such embodiments, the one or more servers must identify the player before enabling game play on the personal gaming device (or, in some embodiments, before enabling monetary wager-based game play on the personal gaming device). In these embodiments, the player must identify herself to the one or more servers, such as by inputting the player's unique username and password combination, providing an input to a biometric sensor (e.g., a fingerprint sensor, a retinal sensor, a voice sensor, or a facial-recognition sensor), or providing any other suitable information.

Once identified, the one or more servers enable the player to establish an account balance from which the player can draw credits usable to wager on plays of a game. In certain embodiments, the one or more servers enable the player to initiate an electronic funds transfer to transfer funds from a bank account to the player's account balance. In other embodiments, the one or more servers enable the player to make a payment using the player's credit card, debit card, or other suitable device to add money to the player's account balance. In other embodiments, the one or more servers enable the player to add money to the player's account balance via a peer-to-peer type application, such as PayPal or Venmo. The one or more servers also enable the player to cash out the player's account balance (or part of it) in any suitable manner, such as via an electronic funds transfer, by initiating creation of a paper check that is mailed to the player, or by initiating printing of a voucher at a kiosk in a gaming establishment.

In certain embodiments, the one or more servers include a payment server that handles establishing and cashing out players' account balances and a separate game server configured to determine the outcome and any associated award for a play of a game. In these embodiments, the game server is configured to communicate with the personal gaming device and the payment device, and the personal gaming device and the payment device are not configured to directly communicate with one another. In these embodiments, when the game server receives data representing a request to start a play of a game at a desired wager, the game server sends data representing the desired wager to the payment server. The payment server determines whether the player's account balance can cover the desired wager (i.e., includes a monetary balance at least equal to the desired wager).

If the payment server determines that the player's account balance cannot cover the desired wager, the payment server notifies the game server, which then instructs the personal gaming device to display a suitable notification to the player that the player's account balance is too low to place the desired wager. If the payment server determines that the player's account balance can cover the desired wager, the payment server deducts the desired wager from the account balance and notifies the game server. The game server then determines an outcome and any associated award for the play of the game. The game server notifies the payment server of any nonzero award, and the payment server increases the player's account balance by the nonzero award. The game server sends data representing the outcome and any award to the personal gaming device, which displays the outcome and any award.

In certain embodiments, the one or more servers enable web-based game play using a personal gaming device only if the personal gaming device satisfies one or more jurisdictional requirements. In one embodiment, the one or more servers enable web-based game play using the personal gaming device only if the personal gaming device is located within a designated geographic area (such as within certain state or county lines or within the boundaries of a gaming establishment). In this embodiment, the geolocation module of the personal gaming device determines the location of the personal gaming device and sends the location to the one or more servers, which determine whether the personal gaming device is located within the designated geographic area. In various embodiments, the one or more servers enable non-monetary wager-based game play if the personal gaming device is located outside of the designated geographic area.

In various embodiments, the gaming system includes an EGM configured to communicate with a personal gaming device—such as a smartphone, a tablet computer, a desktop computer, or a laptop computer—to enable tethered mobile game play using the personal gaming device. Generally, in these embodiments, the EGM establishes communication with the personal gaming device and enables the player to play games on the EGM remotely via the personal gaming device. In certain embodiments, the gaming system includes a geo-fence system that enables tethered game play within a particular geographic area but not outside of that geographic area. Examples of tethering an EGM to a personal gaming device and geo-fencing are described in U.S. Patent Appl. Pub. No. 2013/0267324, entitled “Remote Gaming Method Allowing Temporary Inactivation Without Terminating Playing Session Due to Game Inactivity,” which is incorporated herein by reference.

Social Network Integration

In certain embodiments, the gaming system is configured to communicate with a social network server that hosts or partially hosts a social networking website via a data network (such as the Internet) to integrate a player's gaming experience with the player's social networking account. This enables the gaming system to send certain information to the social network server that the social network server can use to create content (such as text, an image, and/or a video) and post it to the player's wall, newsfeed, or similar area of the social networking website accessible by the player's connections (and in certain cases the public) such that the player's connections can view that information. This also enables the gaming system to receive certain information from the social network server, such as the player's likes or dislikes or the player's list of connections. In certain embodiments, the gaming system enables the player to link the player's player account to the player's social networking account(s). This enables the gaming system to, once it identifies the player and initiates a gaming session (such as via the player logging in to a website (or an application) on the player's personal gaming device or via the player inserting the player's player tracking card into an EGM), link that gaming session to the player's social networking account(s). In other embodiments, the gaming system enables the player to link the player's social networking account(s) to individual gaming sessions when desired by providing the required login information.

For instance, in one embodiment, if a player wins a particular award (e.g., a progressive award or a jackpot award) or an award that exceeds a certain threshold (e.g., an award exceeding $1,000), the gaming system sends information about the award to the social network server to enable the server to create associated content (such as a screenshot of the outcome and associated award) and to post that content to the player's wall (or other suitable area) of the social networking website for the player's connections to see (and to entice them to play). In another embodiment, if a player joins a multiplayer game and there is another seat available, the gaming system sends that information to the social network sever to enable the server to create associated content (such as text indicating a vacancy for that particular game) and to post that content to the player's wall (or other suitable area) of the social networking website for the player's connections to see (and to entice them to fill the vacancy). In another embodiment, if the player consents, the gaming system sends advertisement information or offer information to the social network server to enable the social network server to create associated content (such as text or an image reflecting an advertisement and/or an offer) and to post that content to the player's wall (or other suitable area) of the social networking website for the player's connections to see. In another embodiment, the gaming system enables the player to recommend a game to the player's connections by posting a recommendation to the player's wall (or other suitable area) of the social networking website.

Differentiating Certain Gaming Systems from General Purpose Computing Devices

Certain of the gaming systems described herein, such as EGMs located in a casino or another gaming establishment, include certain components and/or are configured to operate in certain manners that differentiate these systems from general purpose computing devices, i.e., certain personal gaming devices such as desktop computers and laptop computers.

For instance, EGMs are highly regulated to ensure fairness, and, in many cases, EGMs are configured to award monetary awards up to multiple millions of dollars. To satisfy security and regulatory requirements in a gaming environment, hardware and/or software architectures are implemented in EGMs that differ significantly from those of general purpose computing devices. For purposes of illustration, a description of EGMs relative to general purpose computing devices and some examples of these additional (or different) hardware and/or software architectures found in EGMs are described below.

At first glance, one might think that adapting general purpose computing device technologies to the gaming industry and EGMs would be a simple proposition because both general purpose computing devices and EGMs employ processors that control a variety of devices. However, due to at least: (1) the regulatory requirements placed on EGMs, (2) the harsh environment in which EGMs operate, (3) security requirements, and (4) fault tolerance requirements, adapting general purpose computing device technologies to EGMs can be quite difficult. Further, techniques and methods for solving a problem in the general purpose computing device industry, such as device compatibility and connectivity issues, might not be adequate in the gaming industry. For instance, a fault or a weakness tolerated in a general purpose computing device, such as security holes in software or frequent crashes, is not tolerated in an EGM because in an EGM these faults can lead to a direct loss of funds from the EGM, such as stolen cash or loss of revenue when the EGM is not operating properly or when the random outcome determination is manipulated.

Certain differences between general purpose computing devices and EGMs are described below. A first difference between EGMs and general purpose computing devices is that EGMs are state-based systems. A state-based system stores and maintains its current state in a non-volatile memory such that, in the event of a power failure or other malfunction, the state-based system can return to that state when the power is restored, or the malfunction is remedied. For instance, for a state-based EGM, if the EGM displays an award for a game of chance but the power to the EGM fails before the EGM provides the award to the player, the EGM stores the pre-power failure state in a non-volatile memory, returns to that state upon restoration of power, and provides the award to the player. This requirement affects the software and hardware design on EGMs. General purpose computing devices are not state-based machines, and a majority of data is usually lost when a malfunction occurs on a general purpose computing device.

A second difference between EGMs and general purpose computing devices is that, for regulatory purposes, the software on the EGM utilized to operate the EGM has been designed to be static and monolithic to prevent cheating by the operator of the EGM. For instance, one solution that has been employed in the gaming industry to prevent cheating and to satisfy regulatory requirements has been to manufacture an EGM that can use a proprietary processor running instructions to provide the game of chance from an EPROM or other form of non-volatile memory. The coding instructions on the EPROM are static (non-changeable) and must be approved by a gaming regulators in a particular jurisdiction and installed in the presence of a person representing the gaming jurisdiction. Any changes to any part of the software required to generate the game of chance, such as adding a new device driver used to operate a device during generation of the game of chance, can require burning a new EPROM approved by the gaming jurisdiction and reinstalling the new EPROM on the EGM in the presence of a gaming regulator. Regardless of whether the EPROM solution is used, to gain approval in most gaming jurisdictions, an EGM must demonstrate sufficient safeguards that prevent an operator or a player of an EGM from manipulating the EGM's hardware and software in a manner that gives him an unfair, and in some cases illegal, advantage.

A third difference between EGMs and general purpose computing devices is authentication-EGMs storing code are configured to authenticate the code to determine if the code is unaltered before executing the code. If the code has been altered, the EGM prevents the code from being executed. The code authentication requirements in the gaming industry affect both hardware and software designs on EGMs. Certain EGMs use hash functions to authenticate code. For instance, one EGM stores game program code, a hash function, and an authentication hash (which may be encrypted). Before executing the game program code, the EGM hashes the game program code using the hash function to obtain a result hash and compares the result hash to the authentication hash. If the result hash matches the authentication hash, the EGM determines that the game program code is valid and executes the game program code. If the result hash does not match the authentication hash, the EGM determines that the game program code has been altered (i.e., may have been tampered with) and prevents execution of the game program code. Examples of EGM code authentication are described in U.S. Pat. No. 6,962,530, entitled “Authentication in a Secure Computerized Gaming System”; U.S. Pat. No. 7,043,641, entitled “Encryption in a Secure Computerized Gaming System”; U.S. Pat. No. 7,201,662, entitled “Method and Apparatus for Software Authentication”; and U.S. Pat. No. 8,627,097, entitled “System and Method Enabling Parallel Processing of Hash Functions Using Authentication Checkpoint Hashes,” which are incorporated herein by reference.

A fourth difference between EGMs and general purpose computing devices is that EGMs have unique peripheral device requirements that differ from those of a general purpose computing device, such as peripheral device security requirements not usually addressed by general purpose computing devices. For instance, monetary devices, such as coin dispensers, bill validators, and ticket printers and computing devices that are used to govern the input and output of cash or other items having monetary value (such as tickets) to and from an EGM have security requirements that are not typically addressed in general purpose computing devices. Therefore, many general purpose computing device techniques and methods developed to facilitate device connectivity and device compatibility do not address the emphasis placed on security in the gaming industry.

To address some of the issues described above, a number of hardware/software components and architectures are utilized in EGMs that are not typically found in general purpose computing devices. These hardware/software components and architectures, as described below in more detail, include but are not limited to watchdog timers, voltage monitoring systems, state-based software architecture and supporting hardware, specialized communication interfaces, security monitoring, and trusted memory.

Certain EGMs use a watchdog timer to provide a software failure detection mechanism. In a normally operating EGM, the operating software periodically accesses control registers in the watchdog timer subsystem to “re-trigger” the watchdog. Should the operating software fail to access the control registers within a preset timeframe, the watchdog timer will timeout and generate a system reset. Typical watchdog timer circuits include a loadable timeout counter register to enable the operating software to set the timeout interval within a certain range of time. A differentiating feature of some circuits is that the operating software cannot completely disable the function of the watchdog timer. In other words, the watchdog timer always functions from the time power is applied to the board.

Certain EGMs use several power supply voltages to operate portions of the computer circuitry. These can be generated in a central power supply or locally on the computer board. If any of these voltages falls out of the tolerance limits of the circuitry they power, unpredictable operation of the EGM may result. Though most modern general purpose computing devices include voltage monitoring circuitry, these types of circuits only report voltage status to the operating software. Out of tolerance voltages can cause software malfunction, creating a potential uncontrolled condition in the general purpose computing device. Certain EGMs have power supplies with relatively tighter voltage margins than that required by the operating circuitry. In addition, the voltage monitoring circuitry implemented in certain EGMs typically has two thresholds of control. The first threshold generates a software event that can be detected by the operating software and an error condition then generated. This threshold is triggered when a power supply voltage falls out of the tolerance range of the power supply but is still within the operating range of the circuitry. The second threshold is set when a power supply voltage falls out of the operating tolerance of the circuitry. In this case, the circuitry generates a reset, halting operation of the EGM.

As described above, certain EGMs are state-based machines. Different functions of the game provided by the EGM (e.g., bet, play, result, points in the graphical presentation, etc.) may be defined as a state. When the EGM moves a game from one state to another, the EGM stores critical data regarding the game software in a custom non-volatile memory subsystem. This ensures that the player's wager and credits are preserved and to minimize potential disputes in the event of a malfunction on the EGM. In general, the EGM does not advance from a first state to a second state until critical information that enables the first state to be reconstructed has been stored. This feature enables the EGM to recover operation to the current state of play in the event of a malfunction, loss of power, etc. that occurred just before the malfunction. In at least one embodiment, the EGM is configured to store such critical information using atomic transactions.

Generally, an atomic operation in computer science refers to a set of operations that can be combined so that they appear to the rest of the system to be a single operation with only two possible outcomes: success or failure. As related to data storage, an atomic transaction may be characterized as series of database operations which either all occur, or all do not occur. A guarantee of atomicity prevents updates to the database occurring only partially, which can result in data corruption.

To ensure the success of atomic transactions relating to critical information to be stored in the EGM memory before a failure event (e.g., malfunction, loss of power, etc.), memory that includes one or more of the following criteria be used: direct memory access capability; data read/write capability which meets or exceeds minimum read/write access characteristics (such as at least 5.08 Mbytes/sec (Read) and/or at least 38.0 Mbytes/sec (Write)). Memory devices that meet or exceed the above criteria may be referred to as “fault-tolerant” memory devices.

Typically, battery-backed RAM devices may be configured to function as fault-tolerant devices according to the above criteria, whereas flash RAM and/or disk drive memory are typically not configurable to function as fault-tolerant devices according to the above criteria. Accordingly, battery-backed RAM devices are typically used to preserve EGM critical data, although other types of non-volatile memory devices may be employed. These memory devices are typically not used in typical general purpose computing devices.

Thus, in at least one embodiment, the EGM is configured to store critical information in fault-tolerant memory (e.g., battery-backed RAM devices) using atomic transactions. Further, in at least one embodiment, the fault-tolerant memory is able to successfully complete all desired atomic transactions (e.g., relating to the storage of EGM critical information) within a time period of 200 milliseconds or less. In at least one embodiment, the time period of 200 milliseconds represents a maximum amount of time for which sufficient power may be available to the various EGM components after a power outage event has occurred at the EGM.

As described previously, the EGM may not advance from a first state to a second state until critical information that enables the first state to be reconstructed has been atomically stored. After the state of the EGM is restored during the play of a game of chance, game play may resume, and the game may be completed in a manner that is no different than if the malfunction had not occurred. Thus, for example, when a malfunction occurs during a game of chance, the EGM may be restored to a state in the game of chance just before when the malfunction occurred. The restored state may include metering information and graphical information that was displayed on the EGM in the state before the malfunction. For example, when the malfunction occurs during the play of a card game after the cards have been dealt, the EGM may be restored with the cards that were previously displayed as part of the card game. As another example, a bonus game may be triggered during the play of a game of chance in which a player is required to make a number of selections on a video display screen. When a malfunction has occurred after the player has made one or more selections, the EGM may be restored to a state that shows the graphical presentation just before the malfunction including an indication of selections that have already been made by the player. In general, the EGM may be restored to any state in a plurality of states that occur in the game of chance that occurs while the game of chance is played or to states that occur between the play of a game of chance.

Game history information regarding previous games played such as an amount wagered, the outcome of the game, and the like may also be stored in a non-volatile memory device. The information stored in the non-volatile memory may be detailed enough to reconstruct a portion of the graphical presentation that was previously presented on the EGM and the state of the EGM (e.g., credits) at the time the game of chance was played. The game history information may be utilized in the event of a dispute. For example, a player may decide that in a previous game of chance that they did not receive credit for an award that they believed they won. The game history information may be used to reconstruct the state of the EGM before, during, and/or after the disputed game to demonstrate whether the player was correct or not in the player's assertion. Examples of a state-based EGM, recovery from malfunctions, and game history are described in U.S. Pat. No. 6,804,763, entitled “High Performance Battery Backed RAM Interface”; U.S. Pat. No. 6,863,608, entitled “Frame Capture of Actual Game Play”; U.S. Pat. No. 7,111,141, entitled “Dynamic NV-RAM”; and U.S. Pat. No. 7,384,339, entitled, “Frame Capture of Actual Game Play,” which are incorporated herein by reference.

Another feature of EGMs is that they often include unique interfaces, including serial interfaces, to connect to specific subsystems internal and external to the EGM. The serial devices may have electrical interface requirements that differ from the “standard” EIA serial interfaces provided by general purpose computing devices. These interfaces may include, for example, Fiber Optic Serial, optically coupled serial interfaces, current loop style serial interfaces, etc. In addition, to conserve serial interfaces internally in the EGM, serial devices may be connected in a shared, daisy-chain fashion in which multiple peripheral devices are connected to a single serial channel.

The serial interfaces may be used to transmit information using communication protocols that are unique to the gaming industry. For example, IGT's Netplex is a proprietary communication protocol used for serial communication between EGMs. As another example, SAS is a communication protocol used to transmit information, such as metering information, from an EGM to a remote device. Often SAS is used in conjunction with a player tracking system.

Certain EGMs may alternatively be treated as peripheral devices to a casino communication controller and connected in a shared daisy chain fashion to a single serial interface. In both cases, the peripheral devices are assigned device addresses. If so, the serial controller circuitry must implement a method to generate or detect unique device addresses. General purpose computing device serial ports are not able to do this.

Security monitoring circuits detect intrusion into an EGM by monitoring security switches attached to access doors in the EGM cabinet. Access violations result in suspension of game play and can trigger additional security operations to preserve the current state of game play. These circuits also function when power is off by use of a battery backup. In power-off operation, these circuits continue to monitor the access doors of the EGM. When power is restored, the EGM can determine whether any security violations occurred while power was off, e.g., via software for reading status registers. This can trigger event log entries and further data authentication operations by the EGM software.

Trusted memory devices and/or trusted memory sources are included in an EGM to ensure the authenticity of the software that may be stored on less secure memory subsystems, such as mass storage devices. Trusted memory devices and controlling circuitry are typically designed to not enable modification of the code and data stored in the memory device while the memory device is installed in the EGM. The code and data stored in these devices may include authentication algorithms, random number generators, authentication keys, operating system kernels, etc. The purpose of these trusted memory devices is to provide gaming regulatory authorities a root trusted authority within the computing environment of the EGM that can be tracked and verified as original. This may be accomplished via removal of the trusted memory device from the EGM computer and verification of the secure memory device contents is a separate third party verification device. Once the trusted memory device is verified as authentic and based on the approval of the verification algorithms included in the trusted device, the EGM is enabled to verify the authenticity of additional code and data that may be located in the gaming computer assembly, such as code and data stored on hard disk drives. Examples of trusted memory devices are described in U.S. Pat. No. 6,685,567, entitled “Process Verification,” which is incorporated herein by reference.

In at least one embodiment, at least a portion of the trusted memory devices/sources may correspond to memory that cannot easily be altered (e.g., “unalterable memory”) such as EPROMS, PROMS, Bios, Extended Bios, and/or other memory sources that are able to be configured, verified, and/or authenticated (e.g., for authenticity) in a secure and controlled manner.

According to one embodiment, when a trusted information source is in communication with a remote device via a network, the remote device may employ a verification scheme to verify the identity of the trusted information source. For example, the trusted information source and the remote device may exchange information using public and private encryption keys to verify each other's identities. In another embodiment, the remote device and the trusted information source may engage in methods using zero knowledge proofs to authenticate each of their respective identities.

EGMs storing trusted information may utilize apparatuses or methods to detect and prevent tampering. For instance, trusted information stored in a trusted memory device may be encrypted to prevent its misuse. In addition, the trusted memory device may be secured behind a locked door. Further, one or more sensors may be coupled to the memory device to detect tampering with the memory device and provide some record of the tampering. In yet another example, the memory device storing trusted information might be designed to detect tampering attempts and clear or erase itself when an attempt at tampering has been detected. Examples of trusted memory devices/sources are described in U.S. Pat. No. 7,515,718, entitled “Secured Virtual Network in a Gaming Environment,” which is incorporated herein by reference.

Mass storage devices used in a general purpose computing devices typically enable code and data to be read from and written to the mass storage device. In a gaming environment, modification of the gaming code stored on a mass storage device is strictly controlled and would only be enabled under specific maintenance type events with electronic and physical enablers required. Though this level of security could be provided by software, EGMs that include mass storage devices include hardware level mass storage data protection circuitry that operates at the circuit level to monitor attempts to modify data on the mass storage device and will generate both software and hardware error triggers should a data modification be attempted without the proper electronic and physical enablers being present. Examples of using a mass storage device are described in U.S. Pat. No. 6,149,522, entitled “Method of Authenticating Game Data Sets in an Electronic Casino Gaming System,” which is incorporated herein by reference.

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.
