General Construction of Gaming System
The gaming system can take a number of different forms. In a first form, a standalone gaming machine is provided wherein all or most components required for implementing the game are present in a player operable gaming machine.
In a second form, a distributed architecture is provided wherein some of the components required for implementing the game are present in a player operable gaming machine and some of the components required for implementing the game are located remotely relative to the gaming machine. For example, a “thick client” architecture may be used wherein part of the game is executed on a player operable gaming machine and part of the game is executed remotely, such as by a gaming server; or a “thin client” architecture may be used wherein most of the game is executed remotely such as by a gaming server and a player operable gaming machine is used only to display audible and/or visible gaming information to the player and receive gaming inputs from the player.
However, it will be understood that other arrangements are envisaged. For example, architecture may be provided wherein a gaming machine is networked to a gaming server and the respective functions of the gaming machine and the gaming server are selectively modifiable. For example, the gaming system may operate in standalone gaming machine mode, “thick client” mode or “thin client” mode depending on the game being played, operating conditions, and so on. Other variations will be apparent to persons skilled in the art.
Referring to FIG. 1, the gaming system 1 has several core components. At the broadest level, the core components are a player interface 50 and a game controller 60. The player interface 50 enables manual interaction between a player and gaming system 1, and for this purpose includes input/output components required for the player to enter instructions to play a game and observe game outcomes.
Components of the player interface may vary from embodiment to embodiment but will typically include a credit mechanism 52 to enable a player to input credits. For example, in some embodiments, credit mechanism 52 may include a credit input mechanism 52.1 to receive a physical item representing a monetary value for establishing a credit balance. The credit balance may be increasable and decreasable based on wagering activities. Based on the established credit balance, the gaming system 1 initiates a game. In some embodiments, the credit mechanism 52 also includes a payout mechanism 52.2 to cause a payout associated with the credit balance. The player interface may also include one or more displays 54, a game play mechanism 56 including one or more input devices that enable a player to input game play instructions (e.g. to place a wager), and one or more speakers 58. In some embodiments, each of the displays 54 includes a plurality of display positions. In other embodiments, each of the displays 54 includes a plurality of display areas. Each of the display areas includes a plurality of display positions. In the embodiment shown, the display 54 also includes a credit meter 54.1. In some embodiments, credit meter 54.1 displays credits available, credits bet, and/or credits won.
Game controller 60 is in data communication with player interface 50 and typically includes a processor 62 that processes game play instructions in accordance with game play rules and outputs game play outcomes to the display(s) 54. Typically, the game play rules are stored as program code in a memory 64 but can also be hardwired. In some embodiments, the memory 54 may also store data indicative of a plurality of symbols, pay tables, images, and other information to be used in games. Herein the term “processor” is used to refer generically to any device that can process game play instructions in accordance with game play rules and may include: a microprocessor, microcontroller, programmable logic device or other computational device, a general purpose computer (e.g. a PC) or a server. That is, a processor may be provided by any suitable logic circuitry for receiving inputs, processing them in accordance with instructions stored in memory and generating outputs (for example on the display). Such processors are sometimes also referred to as central processing units (CPUs). Most processors are general purpose units, however, it is also known to provide a specific purpose processor using an application specific integrated circuit (ASIC) or a field programmable gate array (FPGA).
Referring to FIG. 2, a gaming system in the form of a standalone gaming machine 10 includes a console 12 having a display 14 on which are displayed representations of a game 16 that can be played by a player. Mid-trim 20 of the gaming machine 10 houses a bank of buttons 22 for enabling a player to interact with the gaming machine, in particular during game play. The mid-trim 20 also houses a credit input mechanism 24 (similar to credit input mechanism 52.1 of FIG. 1) which in this example includes a coin input chute 24A and a bill collector 24B. Other credit input mechanisms may also be employed, for example, a card reader for reading a smart card, debit card or credit card. Other gaming machines may be configured to accept a ticket such that the credit input mechanism 24 may have a ticket reader (not shown) for reading tickets having a value and crediting the player based on the face value of the ticket.

In the embodiment, memory 64 also includes a game rule memory module 64.4 that stores a plurality of game rules.
Persons skilled in the art will appreciate that some or all of the components of the game controller 60 could be alternatively implemented. For example, in some embodiments, the game controller 60 and its components are implemented in the form of a dedicated circuit, or an individual application-specific-integrated-circuit (ASIC). In other embodiments, game controller 60 and its components is implemented as an individual ASIC. In other embodiments, some or all of the game controller components may be individually or collectively implemented as software modules, controllers, and/or circuitries.
In the embodiment, game controller 60 includes a display controller 621 which is configured to control display 54, a random number generator (RNG) 622 configured to generate a random number, and a timer/counter 623 configured to time and/or count an amount of time and/or a number of games that a base game has been played, for example, without a win, an upgrade, and/or a trigger event. The timer/counter 623 may also count a number of free spins in a feature game. Game controller 60 also includes an optional meter controller 624 configured to generate meter data, for example, for display or storage based on game play, and/or to read meter data from the meter memory 64.2.
Referring back to FIG. 6, the symbol memory module 64.1 further includes data for a plurality of anticipation states 64.5 of a predetermined symbol to be used in a base game, and data for a plurality of free spin states 64.6 of the predetermined symbol to be used a feature game. An exemplary feature game is a plurality of free re-spins of the base game.
FIG. 7A illustrates a first exemplary base game 700 that presents a predetermined symbol 702, and symbols 704, 706 landed on a pay line 708. The base game 700 also shows a pay line text indicator 710 and a siren indicator 712. The base game 700 also shows a number of credit meters, including a bet meter 714, a win meter 716, and a credit meter 718, and a denomination value 720. As shown, the base game 700 includes three spinning reels, 721, 722, 723, and one pay line 708. Each of the spinning reels 721, 722, 723 displays one symbol on the one pay line 708. In other embodiments, however, other numbers of spinning reels and pay lines may be used. In addition, spinning reels 721, 722, 723 may display no symbol on pay line 708, where selected symbols may fall above or below pay line 708 although the selected symbols may be partially or fully seen above or below the pay line 708.
FIG. 7B illustrates a second exemplary base game 730 that presents a plurality of symbols 731, 733, 735 landed on pay line 708 in reels, 721, 722, 723, respectively. In this embodiment, the displayed symbols 731, 733, 735 do not form any winning combination. As such, the pay line text indicator 710 and the siren indicator 712 are not actuated. Like the base game 700 of FIG. 7A, the second exemplary base game 730 also shows bet meter 714, win meter 716, credit meter 718, and denomination value 720.
FIG. 7C illustrates a third exemplary base game 740 that presents predetermined symbol 741 and a one-bar symbol 745 landed on pay line 708 in reels 721, 723, respectively. In this embodiment, the displayed predetermined symbol 741 and the displayed one-bar symbol 745 form a winning combination. As such, the pay line text indicator 710 indicates a “WIN” condition, but the siren indicator 712 is not actuated because the predetermined symbol 741 does not transition into a feature game. FIG. 7D illustrates a continuation of the third exemplary base game 740 in which the “WIN” condition of the pay line text indicator 710 begins to glow.
FIG. 7E illustrates a fourth exemplary base game 750 that presents a two-bar symbol 751 and a predetermined symbol 753 landed on pay line 708 in reels 721 and 722, respectively. In this embodiment, the displayed symbols 751, 753 form a winning combination. As such, the pay line text indicator 710 indicates a “WIN” condition, but the siren indicator 712 is not actuated because the predetermined symbol 741 does not transition into a feature game.
Referring now to FIG. 8A, which illustrates an exemplary predetermined symbol 800 (similar to the predetermined symbol 741 of FIG. 7C) in a first anticipation state 801 of the base game 700 (of FIG. 7C). In some embodiments, the predetermined symbol 800 is also a wild symbol. The predetermined symbol 800 includes a plurality of doors 802, symbol text 804, and a siren 806. During the base game 700 (of FIG. 7C), the doors 802 open or partially close, and sandwich the symbol text 804, and the siren 806 flashes or turns off, as discussed above, and hereinafter.
FIG. 8B illustrates an exemplary predetermined symbol 820 in a free-spin state 822 during play of a feature game, or a plurality of free-spin games (of FIG. 8D). When a feature game is initiated, display controller 621 animates the predetermined symbol 820 on the display 54 as described below. For example, display controller 621 may animates that the doors 802 are closed behind the symbol text 804, and the siren 806 is lit.
In some embodiments, the predetermined symbol 800 has a plurality of anticipation states 830 as shown in FIG. 8C. The anticipation states 830 include the first anticipation state 801, as discussed above, with respect to FIG. 8A. The anticipation states 830 also show a second anticipation state 832. When the predetermined symbol 800 lands on a pay line, the predetermined symbol 800 enters the second anticipation state 832, in which the symbol text 804 (“Lock Zone”) begins to separate, the siren 806 lights up, and a glow 833 begins to show in between the symbol text 804. The anticipation states 830 also show a third anticipation state 834. In the third anticipation state 834, the symbol text 804 remains separated, the siren 806 continues to light, the glow 833 continues to show in between the symbol text 804, and the doors 802 begin to partially close. In a fourth anticipation state 836, the symbol text 804 remains separated, the siren 806 continues to light, the glow 833 continues to show in between the symbol text 804, but the doors 802 begin to return to be open. Thereafter, the predetermined symbol 800 returns the first anticipation state 801.
In other words, during play of the base game 700 (of FIG. 7), when the predetermined symbol 800 is displayed, or when the predetermined symbol 800 lands on a pay line, the display 54 animates the predetermined symbol 800 in the anticipation states 830 sequentially. Thus, when a player sees the predetermined symbol 800, the player also sees the doors 802 opening and partially closing, the symbol text 804 separating and rejoining, the glow 833 appearing and disappearing, and the siren 806 flashing and turning off. In some embodiments, the display 54 repeatedly animates the anticipation states 830 in a predetermined amount of time, until a subsequent play of the base game 700 commences, or when an amount of credits have been added to the win meter 716 (of FIG. 7A). Further, in some of embodiments, the display 54 may present the anticipation states 830 as a series of continuous actions depicting movements of the doors 802 and the symbol text 804, appearances of the glow 833, and actuations of the siren 806. However, in other embodiments, the display 54 may present the anticipation states 830 as a series of discrete pictures of movements of the doors 802 and the symbol text 804, appearances of the glow 833, and actuations of the siren 806.
Referring back to FIG. 6, a symbol selection controller 625a selects a plurality of symbols from the symbol data memory module 64.1 for display in the base game 700. The processor 62 also includes a feature controller 625b to determine whether to award a feature game. In some embodiments, the feature award controller 625b randomly determines whether to award a feature game. In other embodiments, the feature controller 625b determines whether to award a feature game based on other criteria, such as, for example, wagers placed.
Referring back to FIG. 6, processor 62 also includes a trigger detection controller 625c to detect or determine if a trigger condition exists or occurs, and whether a feature game is awarded by the feature controller 625b. A trigger condition exists, for example, when the displayed symbols include the predetermined symbol 800 (of FIG. 8A). Another trigger condition exists when the displayed symbols include a predetermined symbol 800 (of FIG. 8A) and the predetermined symbol 800 lands on the pay line 708 (of FIG. 7C). Still another trigger condition exists when the feature controller 625b determines that a feature game is to be awarded and when the displayed symbols include the predetermined symbol 800 (of FIG. 8A). Yet another trigger condition exists when the feature controller 625b determines that a feature game is to be awarded, when the displayed symbols include the predetermined symbol 800 (of FIG. 8A), and when the predetermined symbol 800 lands on the pay line 708 (of FIG. 7E). In some embodiments, the trigger detection controller 625c communicates with the feature controller 625b that when the selected symbols for display include a predetermined symbol 800 (of FIG. 8A), or when the selected symbols for display include a predetermined symbol 800 landing on the pay line 708, such that the feature controller 625b may determine whether to award a feature game. In other embodiments, the trigger detection controller 625c may be configured to detect any or all of the trigger conditions discussed above.
Further, the processor 62 also includes an award controller 625d to communicate with the trigger detection controller 625c and to determine whether an award is to be awarded. For example, when the displayed symbols include a winning combination, the award controller 625d determines an award, or an amount of a prize, with respect to the winning combination. The award controller 625d also determines an award, for example, when the displayed symbols include the predetermined symbol 800 (of FIG. 8A), or when the displayed symbols include a predetermined symbol 800 and when the predetermined symbol 800 lands on the pay line 708. In such cases, when the displayed symbols include a predetermined symbol 800 (of FIG. 8A), or when the displayed predetermined symbol 800 lands on the pay line 708, the award controller 625d determines a number of free-spins of the base game 700 to be awarded. The award controller 625d also awards a prize for the displayed predetermined symbol 800 landing on the pay line 708 in the base game. In such cases, instead of displaying “PAYLINE” in the pay line text indicator 710, the pay line text indicator 710 displays “WIN,” as discussed below. The award controller 625d also determines to award winnings associated with the feature game.
In some embodiments, during the animation of the anticipation states 830, the feature controller 625b may dynamically determine whether to award a feature game. In other embodiments, the feature controller 625b may predetermine whether to award a feature game before the base game 700 (of FIG. 7E) is initiated.
When the feature controller 625b determines a feature game is to be awarded, instead of proceeding to the fourth anticipation state 836, the display controller 621 may control the display 54 to animate the predetermined symbol 800 transitioning into a plurality of free-spin states. In some embodiments, an animation of the anticipation states 830 may last as long as credits are being added to the win meter 716 for an award due for the predetermined symbol 800 landing on the pay line 708. For example, an animation of the anticipation states 830 for a 200-credit win takes longer than an animation of the anticipation states 830 for a 2-credit win. In some embodiments, a player may use the game play mechanism 56 to advance the win meter 718 to display a win total, instead of repeatedly animating the plurality of anticipation states 830 while intermediately incrementing the win meter 718.
FIG. 8D illustrates a plurality of free-spin states 850, when the feature controller 625b determines to award a number of free-spins. The free-spin states 850 include a first free-spin state 851, similar to the first anticipation state 801 (of FIG. 8A). In the first free-spin state 851, the predetermined symbol 800 includes doors 802, symbol text 804, and siren 806. During the transition, the doors 802 are initially open and sandwich the symbol text 804, and the siren 806 is not lit. The free-spin states 850 also show a second free-spin state 852 (similar to the second anticipation state 832), in which the symbol text 804 (“Lock Zone”) begins to separate, the siren 806 lights up, and the glow 833 begins to show between the symbol text 804. In a third free-spin state 853 (similar to the third anticipation state 834), the symbol text 804 remains separated, the siren 806 continues to light, the glow 833 continues to show in between the symbol text 804, and the doors 802 begin to partially close. In a fourth free-spin state 854, the symbol text 804 remains separated, the siren 806 continues to light, but the doors 802 are shut behind the symbol text 804 and the glow 833 is shut behind the doors 802. In a fifth free-spin state 855, the symbol text 804 rejoins, the siren 806 continues to light, and the doors 802 remain shut behind the symbol text 804. Thereafter, a feature game commences, detailed hereinafter.
In short, during play of the base game 700 (of FIG. 7E), when the predetermined symbol 800 lands on a pay line and the feature controller 625b determines that a feature game is to be awarded, the display 54 animates the predetermined symbol 800 in the anticipation states 830, and transitions to animate the free-spin states 850. During the animation of the free-spin states 850, the doors 802 open, partially close, and completely close, the symbol text 804 separates and rejoins, the glow 833 appears and disappears, and the siren 806 lights and turns off.
Referring back to FIG. 6, the feature controller 625b also manages how a feature game is played. FIG. 9A shows a commencement of a feature game 900 that includes a plurality of free spins of the base game 700 with a predetermined symbol 901 (similar to the predetermined symbol 800 in the third free-spin state 853) on the pay line 708. The display 54 displays the predetermined symbol 901 in the third free-spin state 853 where the predetermined symbol 901 lands on pay line 708. The pay line text indicator 710 displays “WIN” indicative of a feature game having been awarded, and the siren 806 flashes. The display 54 displays a banner 908 having an exemplary message “WIN UP TO 20000 CREDITS AT MAX BET” indicative of the base game is being played. The display 54 also displays an original background 912 indicative of the base game 700 being played. Note that the predetermined symbol 901 is now transitioning from the anticipation states 830 to the free-spin states 850, in which doors 904 are closing, and all other symbols visible that are not on pay line 708 remain unchanged.
FIG. 9B shows an animation 920 of the fifth free-spin state 854 that includes a predetermined symbol 901 on the pay line 708. However, the symbol text indicator 708 is not separated and the doors 904 are shut.
FIG. 9C shows an animation 930 of the fifth free-spin state 854 that includes a first chain 932 and a second chain 934 in a process of locking the predetermined symbol 901 on the pay line 708. In some embodiments, the first chain 932 locks the predetermined symbol 901 first. In other embodiments, the second chain 934 locks the predetermined symbol 901 first. Still in other embodiments, the first chain 932 and the second chain 934 lock the predetermined symbol 901 simultaneously. The siren 712 also begins to flash, while the background 912 also begins to change color to indicate that a feature game 936 has been initiated. Further, the banner 908 has also been changed to reflect that the feature game 936 has been initiated with “LOCK ZONE.” In the embodiment shown, two additional predetermined symbols 937, 938 are displayed, with respective doors opened.
FIG. 9D shows an animation 940 of the fifth free-spin state 854 of the feature game 936. In the embodiment shown, the doors of the two additional predetermined symbols 937, 938 are now closed behind the “LOCK ZONE” text, and the sirens 942, 944 begin to flash. However, only the predetermined symbol 901 remains locked to the pay line 708, while reels 722, 723 are free to spin.
FIG. 9E shows an animation 950 of the fifth free-spin state 854 of the feature game 936. In the embodiment shown, a first three-bar symbol 952 and a second three-bar symbol 954 are selected for display. In the embodiment shown, the display controller 621 may animate an attempt to remove the chains 932, 934 by tugging the locked predetermined symbol 901 of FIG. 9D down. As shown in FIG. 9E, the animation 950 begins with the locked predetermined symbol 800 of FIG. 9A being tugged down from the pay line 708. The animation 950 then returns the locked predetermined symbol 901 of FIG. 9A snapping back to the pay line 708.
In other embodiments, the feature controller 625b commences the feature game 900 when a player initiates the feature game 950 via the game play mechanism 56 (of FIG. 1). When the feature game 900 commences, the feature controller 625b also causes the display 54 to spin a plurality of reels for a predetermined amount of time, for example, 1 second. During the commencement, for another predetermined amount of time, for example, 2 seconds, the reels spin, and the siren 806 animates flashing while the background 912 changes color. The reels stop spinning after an amount of time, for example, 2.75 seconds, the free-spin feature game 950 starts. After the feature game is finished, the background 908 returns to its original color, the siren 712 stop flashing, and the banner 908 returns to a base game banner.
As discussed above, the feature game 950 is a plurality of free-spins of the base game 700 with the predetermined symbol 901 padlocked on the pay line 708. In this regard, the award controller 625d (of FIG. 6) determines the number of free-spins of the base game 700 to be awarded.
FIG. 10 illustrates a flow chart of an exemplary lock zone game process 1000. At block 1002, the base game 700 (of FIG. 7A) is played from which a feature game may be triggered. In some embodiments, when the credit input mechanism 52.1 (of FIG. 6) receives a physical item representing a monetary value for establishing a credit balance, the game controller 60 (of FIG. 6) may initiate the base game 700. The game controller 60 also selects symbols from the symbol memory module 64.1 for display. For example, the base game 700 may have three vertically spinning reels 721, 722, 723 which stop to display a 1 by 3 array of game symbols. Awards are achieved based on a symbol outcome shown in the 1×3 array.
The trigger detection controller 625c may determine at block 1004 if a special symbol (such as, for example, the predetermined symbol 800 of FIG. 8A) is displayed during the play of the base game 700. If the trigger detection controller 625c determines at block 1004 that a special symbol is not displayed, or not displayed on the pay line 708, the lock zone game process 1000 at block 1006 determines if another base game is to be played. If no additional base game is to be played, as determined at block 1006, the lock zone game process 1000 ends at block 1008. If an additional base game is to be played, as determined at block 1006, the lock zone game process 1000 returns to block 1002. If the trigger detection controller 625c determines at block 1004 that a special symbol is displayed, or displayed on the pay line 708, the trigger detection controller 625c determines that a trigger condition exists, and the lock zone game process 1000 proceeds to cause the display controller 621 to animate the plurality of anticipation states 830 at block 1010. At block 1012, the feature controller 625b randomly determines if a feature game is to be awarded.
At block 1014, the lock zone game process 1000 determines if a feature game is to be awarded. If the lock zone game process 1000 determines that a feature game is not awarded, the award controller 625d increases the credit balance based on the special symbol, or on the special symbol landed on the pay line 708, at block 1016. At block 1018, the pay mechanism 52.1 then provides a payout based on the credit balance.
However, if the lock zone game process 1000 determines that a feature game is to be awarded, the feature controller 625b at block 1020 causes the display 54 to animate a transition from the plurality of anticipation states 830 to the plurality of free-spin states 850, as discussed above. The lock zone game process 1000 also determines a number of free spins being awarded, and commences a feature game (similar to the feature game 900 of FIG. 9D) at block 1022. At block 1024, the feature controller 625b causes the reels 721, 722, 723 to visually spin, while padlocking any unlocked reels of reels 721, 722, 723 to visually spin, while padlocking the reel with the special symbol so that the padlocked reel does not spin to keep the special symbol locked on the pay line 708. After spinning the unlocked reels of reels 721, 722, 723, the award controller 625d awards a winning, and increases the credit balance based on the winning. In some embodiments, the winning for a subsequent spin is at least equal to the winning for a previous spin. For example, if the winning for a current spin awards 6 credits, the winning for a subsequent spin awards at least 6 credits. For example, if the winning for a current spin will award 6 credits, the winning for a subsequent spin awards at least 6 credits for a total feature game award of 12 credits. Thus, the feature game 900 guarantees a winning in each spin, and increases a total winning as each additional spin is awarded.
Table I below lists an exemplary pay table for the feature game 900 based on wagers placed. For example, when the special symbol is a wild symbol, and when a wager of 2 credits is placed, a combination of 1 wild and a Red 7 pays a 1 Wild win (2× bet), which is 4 credits.

Referring back to FIG. 10, at block 1026, the lock zone game process 1000 determines if the spin at block 1024 is the last spin. If the spin at block 1024 is the last spin, the pay mechanism 52.1 then provides a payout based on the credit balance at block 1018. If the spin at block 1024 is the last spin, the lock zone game process 1000 moves to a next spin at block 1028 and repeats block 1024. If an additional special symbol is displayed on the display 54, the displayed additional special symbol is also padlocked with chains 904. Further, U.S. application Ser. Nos. 29/608,103 and 29/608,104, Attorney Docket Nos. 61807US01 and 61808US01, are incorporated herein by reference.
